Description

A sampling device for solid food detection and a sampling method thereof

Technical Field

The present invention relates to the technical field of food detection, and in particular to a sampling device for solid food detection and a sampling method thereof.

Background Art

Food safety means that food is non-toxic and harmless, meets the necessary nutritional requirements, and does not cause any acute, subacute or chronic harm to human health. During the food production process, it is necessary to sample and test food raw materials and finished products, and different sampling equipment is used for sampling of different forms of food.

For sampling of solids, such as soybean raw materials or wheat raw materials, sampling tubes are often used for sampling, which is convenient to operate. However, sampling with sampling tubes has the defect of inaccurate sampling. Therefore, the announcement number CN117686273B discloses a sampling device for solid food detection and a sampling method thereof, which includes a processing tube, an upper inner tube, a conveying tube and a lower inner tube; a cone is hinged at the bottom of the processing tube, and the cross-sectional shape of the cone is conical, a motor and a lifting frame are arranged above the processing tube, the motor is located at the axial position of the processing tube, and the cross-sectional shape of the lifting frame is U-shaped; a telescopic channel is milled on the circumference of the processing tube, a sampling barrel is telescopically moved in the telescopic channel, a sampling port is reserved on the top of the sampling barrel, and a bellows is arranged between the sampling barrel and the circumference of the conveying tube.

When sampling, the sampling device for solid food detection can sample different positions of solid food according to needs, and the sampling is more accurate. The sample detection results obtained are representative. However, during the specific operation of the sampling device for solid food detection, it is impossible to effectively sample fixed foods under special circumstances. For example, the fixed food contains a lot of water, which causes agglomeration inside the fixed food. Once agglomeration occurs, the sampling operation cannot be completed through the device. There are certain limitations in its use, and the samples obtained are stored together. The specific positions of the samples cannot be distinguished during detection, resulting in reduced detection accuracy.

Therefore, a novel sampling device and sampling method for solid food detection can be used to solve the shortcomings of the prior art.

The present invention also provides a sampling method for solid food detection, characterized in that it comprises the above-mentioned sampling device for solid food detection, and further comprises the following steps:

S1. A controller that cooperates with motor 1, motor 2, motor 3, motor 4 and an electric push rod is installed on the handle. The sampling tube and the material tube are inserted into the solid food by holding the handle, and then the insertion depth is adjusted by the electric push rod to facilitate sampling operations on solid foods at different depths.

S2, after the sampling tube and the material tube are inserted into the solid food, the controller controls the operation of the motor 2, the rotation of the driving end of the motor 2 will drive the screw to rotate, thereby driving the threaded sleeve to move on the screw, and the movement of the threaded sleeve will drive the two sampling tubes to move through two sets of rotating rods and two connecting parts, so that the two sampling tubes are separated, and then the sampling tube is pushed forward again by the electric push rod, and then the driving end of the motor 2 is controlled by the controller to reverse, and at this time the two sampling tubes move to the side close to each other, so that the solid food is wrapped in the two sampling tubes, which is suitable for solid foods of different particle sizes;

S3, after the solid food enters the sampling cylinder, the motor 1 drives the spiral lifting rod to rotate, and the solid food in the sampling cylinder is brought into the material barrel through the spiral lifting rod, and then the solid food is continuously lifted upward from the material barrel. If the sampled sample is agglomerated at this time, the spiral lifting rod will bring the agglomerated solid food out of the discharge pipe 2, into the docking box, and then into the corresponding collection cup through the discharge pipe;

S4. If the sample is dispersed solid food, the spiral lifting rod will take the dispersed solid food out of the discharge pipe 1, and bring the dispersed solid food into the sampling cup for storage through the docking pipe;

S5. After the sampling of the point is completed, the sampling cylinder is manually moved so that the sampling cylinder is located at a different position in the solid food. After each sampling is completed, the motor 3 drives the mounting plate to rotate, so that the sampling cup is rotated and replaced, and the solid food samples sampled at different points are stored separately. At the same time, during the rotation of the mounting plate, the motor 3 drives the gear to rotate, thereby driving the mounting ring to rotate through the meshing teeth, and the rotation of the mounting ring drives the collection cup to rotate, so that the collection cup is replaced;

S6. A sealing plug is installed on the threaded rotation of the collecting cup. When unloading, the sealing plug is removed to pour out the agglomerated solid food in the collecting cup. To take out the sample in the sampling cup, the entire sampling cup needs to be removed. The specific operation is: turn the screw rod, the nut will move on the screw rod, thereby moving the rotating rod, and the rotating rod will drive the stopper to slide on the mounting plate, so that the stopper is separated from the sampling cup. At this time, the sampling cup loses the limit of the stopper and can be removed from the fixed clamp.

Compared with the prior art, the present invention has the following advantages:

1. When sampling, the sampling device for solid food detection can not only perform sampling operations at different positions in the solid food, but also use the openable and closable sampling tube to preliminarily grab the sampled part to determine the sampled part, thereby preventing the solid food at the sampling position from being mixed with the solid food at other positions due to the collapse of the solid food during the sampling process, thereby improving the sampling accuracy. In addition, the grabbing can also dig out the agglomerated solid food, so that the agglomerated solid food can also be taken out, and the agglomeration situation inside the solid food can be observed. The device is not only suitable for dispersed solid food, but also for agglomerated solid food, and its scope of application is expanded.

2. When sampling, the sampling device for solid food detection uses a rotatable collection cup and a sampling cup to store samples collected at different points separately. The difference between samples at different points can be visually observed during later detection, and the storage of solid food can be adjusted based on the difference. Separate storage can also effectively reduce the deviation of detection and make the detection more accurate.

3. When sampling, the sampling device for solid food detection can automatically separate agglomerated solid food from dispersed solid food by utilizing the height difference between the discharge pipe 1 and the discharge pipe 2, so as to avoid the occurrence of detection deviation caused by the mixing of agglomerated solid food and dispersed solid food. At the same time, with the rotatable screening plate, solid food with different agglomeration degrees can be screened, which is suitable for the detection and sampling of solid food with different particle sizes.

In summary, the device can not only sample different positions in solid food, but also maintain the stability of the solid food around the sampling during the sampling process, avoid the surrounding solid food from affecting the solid food in the sampling part, and improve the accuracy of sampling. In addition, it can also sample both agglomerated and dispersed solid foods, and store the sampled samples separately, making the detection more accurate and intuitive.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Embodiment 1: Referring to Figures 1 to 10, a sampling device for solid food detection includes a material barrel 1 and a handle; a sampling part, used in conjunction with the material barrel 1, for sampling solid food, the sampling part includes a spiral lifting rod 22 rotatably installed inside the material barrel 1, and a driving assembly is installed between the spiral lifting rod 22 and the material barrel 1.

The spiral lifting rod 22 is an existing lifting component, which is composed of a spiral blade and a rod. Through the rotation of the rod and the spiral blade, the solid food at the bottom will be automatically lifted to the top. It is an existing structure and its principle will not be explained in detail. Here, the diameter of the spiral blade is the same as the inner diameter of the material barrel 1, which can reduce the omission of solid food.

The driving assembly includes an electric push rod 3 fixedly mounted on the handle, a connecting rod 2 is fixedly mounted on the driving end of the electric push rod 3, a pad 8 is fixedly mounted on the end of the connecting rod 2 away from the electric push rod 3, the pad 8 is fixedly connected to the belt barrel 1 through a plurality of pillars, a motor 10 is fixedly mounted on the pad 8, and the driving end of the motor 10 is fixedly connected to the spiral lifting rod 22;

The electric push rod 3 can drive the connecting rod 2 to move, thereby driving the barrel 1 to move, and is used to extend into solid foods of different depths; the function of the pad 8 is to prevent the driving end of the motor 10 from being subjected to a large bending moment, and can protect the driving end of the motor 10 to ensure the operating efficiency of the motor 10.

The rotation of the driving end of the motor 10 will drive the spiral lifting rod 22 to rotate, and the rotation of the spiral lifting rod 22 will bring the solid food located at the bottom of the belt barrel 1 to the top of the belt barrel 1, thereby realizing the feeding operation of the solid food.

The belt barrel 1 is fixedly connected with a discharge pipe 19, and the discharge pipe 19 is fixedly connected with a butt joint pipe 11, on which two sampling tubes 9 cooperating with the belt barrel 1 are installed through an opening and closing assembly.

For dispersed solid food, the solid food brought up from the bottom of the material barrel 1 will directly enter the docking tube 11 through the discharge tube 19. When sampling, the sampling barrel 9 is driven to move through the opening and closing components to dig and sample the solid food in the sampling part. This can avoid the collapse of the solid food around the sampling part, resulting in inaccurate sampling, thereby improving the accuracy of sampling.

The opening and closing assembly includes a mounting plate 12 fixedly mounted on the butt-jointed tube 11, a bracket fixedly mounted on the mounting plate 12, a motor 2 14 and a disc 13 fixedly mounted on the bracket, two groups of rotating rods rotatably mounted on the disc 13, a clamping jaw 17 rotatably mounted on each of the two groups of rotating rods, a threaded sleeve 15 commonly mounted on the two groups of rotating rods, the threaded sleeve 15 and the two groups of rotating rods are rotatably connected, a screw rod 16 matched with the threaded sleeve 15 is rotatably mounted on the disc 13, the two clamping jaws 17 are fixedly connected to the corresponding sampling tube 9 through a connecting piece 18, and the driving end of the motor 2 14 is fixedly connected to the screw rod 16;

The operation of motor 2 14 is controlled by a controller. The rotation of the driving end of motor 2 14 will drive the screw 16 to rotate, thereby driving the threaded sleeve 15 to move on the screw 16. The movement of the threaded sleeve 15 will drive the two sampling barrels 9 to move through two sets of rotating rods and two connecting parts 18, so that the two sampling barrels 9 are separated. At this time, the sampling barrel 9 is pushed forward again by the electric push rod 3, and then the driving end of motor 2 14 is reversed by the controller. At this time, the two sampling barrels 9 move to the side close to each other, thereby wrapping the solid food in the two sampling barrels 9 (the rotating rod here is an existing technical feature, and the specific operation is not explained here).

Embodiment 2: This embodiment is different from the technical solution of Embodiment 1 in that: referring to Figures 1-3 and 11-15, a first sample storage portion is installed on the butt-joint tube 11, and is used to store the obtained solid food samples. The sample storage portion includes a fixed plate 23 fixedly installed on the butt-joint tube 11, and a mounting plate 4 is rotatably mounted on the fixed plate 23. A plurality of sampling cups 6 are mounted on the mounting plate 4 through a locking assembly.

The locking assembly includes a plurality of arc-shaped fixing clamps 28 fixedly mounted on the mounting plate 4 and matched with the sampling cup 6, a screw 27 is rotatably mounted on the mounting plate 4, a nut 29 is threadedly rotatably mounted on the screw 27, a fixing ring 30 is fixedly mounted on the nut 29, a plurality of rotating rods 31 are rotatably mounted on the fixing ring 30, and a stop block 32 matched with the sampling cup 6 is rotatably mounted on one end of each rotating rod 31 away from the fixing ring 30, and each stop block 32 is slidably connected to the mounting plate 4;

Installation of the sampling cup 6: First, insert the sampling cup 6 into the fixed clamp 28. Since the fixed clamp 28 and the sampling cup 6 are connected by a damping clamp, the sampling cup 6 will not fall off the fixed clamp 28. Then rotate the screw 27, and the nut 29 will move on the screw 27, thereby moving the rotating rod 31. Under the action of the rotating rod 31, the stop block 32 will be driven to slide on the mounting plate 4, so that the stop block 32 will abut against the sampling cup 6, thereby locking the sampling cup 6.

Disassembly of the sampling cup 6: Rotate the screw 27 in the opposite direction, the nut 29 will move on the screw 27, thereby moving the rotating rod 31. The rotating rod 31 will drive the stop block 32 to slide on the mounting plate 4, so that the stop block 32 is separated from the sampling cup 6. At this time, the sampling cup 6 loses the limit of the stop block 32 and can be removed from the fixing clamp 28.

A rotating assembly matched with the mounting plate 4 is installed on the butt joint pipe 11, and the rotating assembly includes a motor 3 25 fixedly installed on the butt joint pipe 11, and a first driving end of the motor 3 25 passes through the fixed plate 23 and the mounting plate 4 and is fixedly connected, and the first driving end of the motor 3 25 is rotatably connected to the fixed plate 23;

After each sampling is completed, the motor three 25 will drive the mounting plate 4 to rotate, thereby rotating and replacing the sampling cup 6, so as to separately store the samples of solid food sampled at different points, which is convenient for more intuitive detection.

A screening disc 24 is rotatably mounted on the fixed disc 23, a motor 26 is fixedly mounted on the butt joint 11, a rubber wheel is fixedly mounted on the driving end of the motor 26, and a rubber ring matching the rubber wheel is fixedly mounted on the periphery of the screening disc 24; a plurality of discharge ports are provided on the screening disc 24, and screening nets with different mesh sizes are fixedly mounted on two of the discharge ports.

Motor 4 26 will drive the rubber wheel to rotate, thereby driving the screening disc 24 to rotate through the friction between the rubber ring, so as to change the angle of the screening disc 24. Different screening meshes on the screening disc 24 are selected according to the particle size of the solid food. The screening mesh is not installed on the discharge port in the middle, which is suitable for solid food with larger particle size.

Embodiment 3: This embodiment is different from the technical solution of Embodiment 2 in that: with reference to FIGS. 1-3 and 16-18, a second sample storage portion is installed on the belt barrel 1 for storing agglomerated solid food samples, and the second sample storage portion includes a discharge pipe 20 fixedly connected to the belt barrel 1, the discharge pipe 20 is fixedly connected to a docking box 33, a fixed cover 38 is fixedly installed on the docking box 33, a discharge pipe 36 is fixedly installed on the fixed cover 38, the discharge pipe 36 is connected to the docking box 33, a mounting ring 5 is rotatably installed on the fixed cover 38, a plurality of collecting cups 7 matching the discharge pipe 36 are fixedly installed on the mounting ring 5, and a driving component matching the mounting ring 5 is installed on the discharge pipe 20.

The driving assembly includes a shaft rotatably mounted on the discharge pipe 20, a gear 34 is fixedly mounted on the shaft, a plurality of meshing teeth matching the gear 34 are fixedly mounted on the mounting ring 5, and the second driving end of the motor 3 25 is connected to the gear 34 via a universal flexible shaft 35 (the universal flexible shaft 35 is a detachable design, which is not shown in Figures 1 to 3, so Figures 1 to 3 are schematic diagrams after the universal flexible shaft 35 is disassembled);

Each time the sampling cup 6 is rotated and replaced, the universal flexible shaft 35 will be driven to rotate through the motor 3 25, thereby driving the gear 34 to rotate, and driving the mounting ring 5 to rotate through the meshing teeth. The rotation of the mounting ring 5 will drive the collecting cup 7 to rotate, thereby replacing the collecting cup 7. When the spiral lifting rod 22 rotates, some agglomerated solid food will be broken up, and the agglomerated solid food will be divided into an agglomerated part and a non-agglomerated part. The agglomerated part will enter the collecting cup 7, and the non-agglomerated part will enter the sampling cup 6. In this way, the collecting cup 7 and the sampling cup 6 maintain synchronous operation, which can facilitate the corresponding solid samples at the same position in subsequent detection, avoid confusion, and improve detection accuracy.

The height of the discharge pipe 19 is lower than that of the discharge pipe 20 (as shown in FIG. 3 ), and a leakage cover 21 is fixedly installed inside the discharge pipe 19 , and the angle between the discharge pipe 19 and the material barrel 1 is seventy-five degrees. The purpose of this is to make the sampling cup 6 installed on the mounting plate 4 have a certain inclination angle, so that when the sampling cup 6 is removed, the probability of solid food in the sampling cup 6 falling is reduced. The specific angle can be determined according to the amount of sampling and is selected during the production process.

The specific operation steps of this device are as follows:

First, install the sampling cup 6: insert the sampling cup 6 into the fixed clamp 28. Since the fixed clamp 28 and the sampling cup 6 are connected by a damping clamp, the sampling cup 6 will not fall off the fixed clamp 28. Then rotate the screw 27, and the nut 29 will move on the screw 27, thereby moving the rotating rod 31. Under the action of the rotating rod 31, the stop block 32 will slide on the mounting plate 4, so that the stop block 32 will abut against the sampling cup 6, thereby locking the sampling cup 6.

A controller that cooperates with motor 1 10, motor 2 14, motor 3 25, motor 4 26 and electric push rod 3 is installed on the handle. The sampling tube 9 and the material tube 1 are inserted into the solid food by holding the handle, and then the insertion depth is adjusted by the electric push rod 3 to facilitate sampling operations on solid foods at different depths.

After the sampling tube 9 and the material tube 1 are inserted into the solid food, the controller controls the motor 2 14 to operate. The rotation of the driving end of the motor 2 14 will drive the screw 16 to rotate, thereby driving the threaded sleeve 15 to move on the screw 16. The movement of the threaded sleeve 15 will drive the two sampling tubes 9 to move through two groups of rotating rods and two connecting parts, so that the two sampling tubes 9 are separated. At this time, the sampling tube 9 is pushed forward again by the electric push rod 3, and then the driving end of the motor 2 14 is reversed by the controller. At this time, the two sampling tubes 9 move to the side close to each other, thereby wrapping the solid food in the two sampling tubes 9, which is suitable for solid foods of different particle sizes.

After the solid food enters the sampling barrel 9, the spiral lifting rod 22 is driven to rotate by the motor 10, and the solid food in the sampling barrel 9 is brought into the material barrel 1 through the spiral lifting rod 22, and then the solid food is continuously lifted upward from the material barrel 1. If the sample is agglomerated at this time, the spiral lifting rod 22 will bring the agglomerated solid food out of the discharge pipe 20, into the docking box 33, and then into the corresponding collection cup 7 through the discharge pipe 36.

If the sample is dispersed solid food, the spiral lifting rod 22 will bring the dispersed solid food out of the discharge pipe 19, and bring the dispersed solid food into the sampling cup 6 for storage through the docking pipe 11.

After the sampling of the point is completed, the sampling tube 9 is manually moved so that the sampling tube 9 is located at different positions in the solid food. After each sampling is completed, the motor three 25 will drive the mounting plate 4 to rotate, thereby rotating and replacing the sampling cup 6, and the samples of solid food sampled at different points will be stored separately. At the same time, during the rotation of the mounting plate 4, the motor three 25 will also drive the gear 34 to rotate, thereby driving the mounting ring 5 to rotate through the meshing teeth. The rotation of the mounting ring 5 will drive the collecting cup 7 to rotate, thereby replacing the collecting cup 7.

A sealing plug 37 is threadedly installed on the collecting cup 7. When unloading, the sealing plug 37 is removed to pour out the agglomerated solid food in the collecting cup 7. To take out the sample in the sampling cup 6, the entire sampling cup 6 needs to be removed. The specific operation is: rotate the screw 27, the nut 29 will move on the screw 27, so that the rotating rod 31 moves, and the rotating rod 31 will drive the block 32 to slide on the mounting plate 4, so that the block 32 is separated from the sampling cup 6. At this time, the sampling cup 6 loses the limit of the block 32 and can be removed from the fixing clamp 28.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

The sampling method of the sampling device for solid food detection according to any one of claims 1 to 9, characterized in that it comprises the following steps: S1. A controller that cooperates with motor 1 (10), motor 2 (14), motor 3 (25), motor 4 (26) and the electric push rod (3) is installed on the handle. The sampling tube (9) and the material tube (1) are inserted into the solid food by holding the handle, and the insertion depth is adjusted by the electric push rod (3) so as to facilitate sampling operations on solid food at different depths. S2, after the sampling tube (9) and the material tube (1) are inserted into the solid food, the controller controls the second motor (14) to operate, the driving end of the second motor (14) rotates to drive the screw (16) to rotate, thereby driving the threaded sleeve (15) to move on the screw (16), the movement of the threaded sleeve (15) drives the two sampling tubes (9) to move through the two sets of rotating rods and the two connecting members (18), so that the two sampling tubes (9) are separated, and then the sampling tube (9) is pushed again by the electric push rod (3), and then the driving end of the second motor (14) is controlled by the controller to reverse, and at this time, the two sampling tubes (9) move to the side close to each other, so that the solid food is wrapped in the two sampling tubes (9), which is suitable for solid food with different particle sizes; S3, after the solid food enters the sampling barrel (9), the motor 1 (10) drives the spiral lifting rod (22) to rotate, and the solid food in the sampling barrel (9) is brought into the material barrel (1) through the spiral lifting rod (22), and then the solid food is continuously lifted upward from the material barrel (1). If the sampled sample is agglomerated at this time, the spiral lifting rod (22) will bring the agglomerated solid food out of the discharge pipe 2 (20), into the docking box (33), and then into the corresponding collection cup (7) through the discharge pipe (36); S4. If the sample is dispersed solid food, the spiral lifting rod (22) will bring the dispersed solid food out of the discharge pipe (19) and bring the dispersed solid food into the sampling cup (6) for storage through the docking pipe (11); S5. After sampling at the point is completed, the sampling tube (9) is manually moved so that the sampling tube (9) is located at a different position in the solid food. After each sampling is completed, the motor three (25) drives the mounting plate (4) to rotate, thereby rotating and replacing the sampling cup (6), and storing the solid food samples taken at different points separately. At the same time, during the rotation of the mounting plate (4), the motor three (25) also drives the gear (34) to rotate, thereby driving the mounting ring (5) to rotate through the meshing teeth. The rotation of the mounting ring (5) drives the collection cup (7) to rotate, thereby replacing the collection cup (7); S6. A sealing plug (37) is installed on the collecting cup (7) by rotating the thread. When unloading, the sealing plug (37) is removed to pour out the agglomerated solid food in the collecting cup (7). The whole sampling cup (6) needs to be removed to take out the sample in the sampling cup (6). The specific operation is as follows: the screw rod (27) is rotated, and the nut (29) moves on the screw rod (27), thereby moving the rotating rod (31). Under the action of the rotating rod (31), the stopper (32) is driven to slide on the mounting plate (4), so that the stopper (32) is separated from the sampling cup (6). At this time, the sampling cup (6) loses the limit of the stopper (32) and can be removed from the fixing clamp (28).
