detailed description

In order to have a further understanding of the technical solution and beneficial effects of the present invention, the technical solution of the present invention and its beneficial effects will be described in detail below with reference to the accompanying drawings.

Fig. 1 and Fig. 2 are respectively the side view schematic diagram and the three-dimensional structure schematic diagram of the present invention, as shown in Fig. 1 and Fig. 2: the present invention provides a kind of vertical vacuum packaging machine, comprises feeding hopper 10, unloading column 20, Packaging system 30, film feeding system 40, vacuum mechanism 50 and control system 60, specifically:

The feeding hopper 10 is located at the top of the vertical vacuum packaging machine, and is used for receiving materials and transporting materials downward.

The feeding column 20 is an internal hollow structure, which is integrally formed under the feed hopper 10. Since the bottom outlet of the feeding column 20 is connected to the opening of the packaging bag when packaging materials, in order to achieve vacuuming , it is necessary to form a closed space between the blanking column 20 and the packaging bag. The present invention chooses to divide the blanking column 20 into a material cylinder 21 and a sealed chamber 22, which is realized by a sealing block assembly 23 set at a suitable height in the middle of the blanking column 20. In this division, the upper part of the sealing block assembly 23 is the barrel 21, the lower part of the sealing block assembly 23 is the sealing chamber 22, and the sealing block assembly 23 is two plate structures on both sides of the feeding column 20; During the cycle, the two plate-shaped structures are in a separated state, the feed hopper 10, the barrel 21 and the sealed chamber 22 are connected inside, and the material falls into the sealed chamber 22 from the feed hopper 10; when the vacuum packaging machine is in the vacuum cycle, the two The plate-shaped structure is in a closed state, the sealing chamber 22 is not connected to the inside of the material barrel 21 and the feeding hopper 10, and a sealed space is formed between the sealing chamber 22 and the packaging bag, so that the vacuuming operation can be completed.

The vacuum mechanism 50 is arranged on one side of the feed hopper 10, communicates with the inside of the feeding column 20 through a vacuum tube 51, and is used to vacuumize the packaging bag when packaging materials;

Specifically, the vacuum packaging machine of the present invention also includes a braking mechanism 52, which is fixedly connected to the vacuum tube 51, and is used to drive the vacuum tube 51 to move up and down under the control of the control system 60, so as to match the movement of the feeding column 20. The packaging cycle realizes vacuuming in the feeding column 20 . For example: when the vacuum packaging machine is in the vacuum packaging cycle, the brake mechanism 52 drives the vacuum tube 51 to move downward, so that the lower end port of the vacuum tube 51 is located in the sealed chamber 22 to help the sealed chamber 22 to achieve vacuuming, and the vacuuming cycle ends Finally, the brake mechanism 52 drives the vacuum tube 51 to move upward, so that the lower port of the vacuum tube 51 is separated from the sealed chamber 22 . In order to cooperate with the movement of the vacuum tube 51 , a perforation matched with the structure of the outer diameter of the vacuum tube 51 can be provided on one of the plates of the sealing block assembly 23 .

The packaging system 30 is arranged under the feeding column 20, and is used to accept the materials in the feeding column 20 and pack them into shape; specifically, the packaging system 30 may further include a manufacturing system for forming packaging bags of a predetermined size and shape. The bag mechanism 31, the heat-sealing mechanism 32 used to seal the packaging bag after vacuuming is completed, and the cutting mechanism 33 used to cut off the formed packaging bag after a packaging cycle ends. The structures, principles and working methods of the bag-making mechanism 31, the heat-sealing mechanism 32 and the cutting mechanism 33 can be understood by those skilled in the art, and the present invention will not be repeated here.

The film feeding system 40 is arranged at the rear of the vertical vacuum packaging machine, and is used to provide the packaging materials required by the packaging system 30; Those skilled in the art can understand that the present invention will not be described in detail here.

The control system 60 is used to control the operation of the feeding hopper 10 , the feeding column 20 , the packaging system 30 , the film feeding system 40 and the vacuum mechanism 50 . The control system 60 of the present invention realizes high-efficiency and high-quality vacuuming by controlling the pumping speed and pumping volume of the vacuum mechanism 50 and the precise cooperation with the packaging system 30 through the microcomputer according to the PLC programming control system instructions; During the vacuum process, the time gap between vacuuming operation and heat sealing, as well as the speed of vacuuming and the amount of air pumping are all important factors affecting the results of vacuum packaging. The optimal working parameters of the vacuum pumping mechanism 50 and the control system 60 of the invention are: in each vacuum packaging cycle, the vacuum degree in the packaging bag is between 800-1400Pa; the working time of each vacuum packaging cycle is between 3-10 seconds, more preferably, the working time of each vacuum packaging cycle is 5 seconds.

In the present invention, the diameter of the vacuum tube 51 that cooperates with the vacuum mechanism 50 is between 18 cm and 22 cm.

In the present invention, the braking structure 52 can preferably be a piston rod.

In the present invention, in order to form a more airtight and more suitable space for vacuuming between the packaging bag and the sealing chamber 22, it is preferable to treat the outer surface of the sealing chamber so that the surface roughness reaches 0.012. It has been proved by many experiments that this roughness is used with the composite film, and the sealing performance is the best.

A complete technological process of the vertical vacuum packaging machine provided by the present invention is as follows: open the discharge valve (not shown in the figure) → the material with a rated weight enters the feed hopper 10 → close the discharge valve → start the vacuum mechanism 50 → seal the chamber Vacuum is formed in 22 → vacuum mechanism 50 is closed → heat sealing mechanism 32 heat seals → cutting mechanism 33 cuts off → packaging is completed.

Specifically: the material falls into the feeding column 20 through the feeding hopper 10. At this time, the control system 60 controls the action of the cylinder (not shown in the figure). The system 60 controls the sealing block assembly 23 to close, the sealing chamber 22 and the packaging bag form a closed space, the vacuuming mechanism 50 starts to work, and after the vacuuming is completed, the heat sealing mechanism 32 and the cutting mechanism 33 perform heat sealing and cutting respectively to complete a vacuum. During the packaging process, the sealing block assembly 23, the heat sealing mechanism 32 and the vacuum tube 51 are all reset, and the vacuuming mechanism 50 stops working, waiting for the next vacuum packaging cycle.

To sum up, the vertical vacuum packaging machine provided by the present invention integrates the advantages of continuous packaging of the vertical packaging machine and vacuuming of the vacuum packaging machine, realizes continuous vacuum packaging, greatly improves work efficiency, and saves labor costs .
