As shown in fig. 2, in some embodiments of the present application, the discharge cartridge 202 and the receiving cartridge 10 are disposed along the first direction X, and the quantitative discharge device 1 further includes a moving assembly 40, the moving assembly 40 including a connection block 401 and a threaded rod 402. The connection block 401 is connected to the discharge cylinder 202, and a screw hole is provided in the connection block 401. The threaded rod 402 is screwed with the connection block 401, and the threaded rod 402 is disposed along the first direction X. One end of the threaded rod 402 is connected to the accommodating cylinder 10, and the threaded rod 402 rotates to drive the connecting block 401 to move along the first direction X relative to the accommodating cylinder 10.

Illustratively, the connection block 401 is a block-shaped entity that can be manufactured using metal, high strength organic materials, and the like. One end of the threaded rod 402 may be threadedly coupled with the receiving cylinder 10. The first direction X may be an axial direction of the accommodating tube 10.

The design of the threaded rod 402 is arranged along a first direction X, which may be a vertical direction perpendicular to the horizontal plane. One end of the threaded rod 402 is connected to the receiving cylinder 10, and the other end is tightly engaged with the connection block 401 by threads.

When the position of discharge tube 202 needs to be adjusted to control the discharge of material, the operator need only rotate threaded rod 402. Due to the self-locking nature and precise fit of the threads, rotation of the threaded rod 402 will drive the connection block 401 in the direction of the threaded rod 402. Since the connection block 401 is connected to the discharge cylinder 202, the discharge cylinder 202 moves accordingly, thereby realizing accurate adjustment of the discharge amount of the material.

According to the technical scheme, operators are allowed to realize accurate control of material discharge through simple mechanical operation under the condition of not directly contacting materials. This not only reduces material contamination and operator safety risks, but also improves work efficiency and accuracy. In addition, due to the stability and reliability of the threaded connection, the assembly can maintain good performance and accuracy during long-term use.

In some embodiments of the present application, the valve assembly 30 includes a piston 301 and a resilient member 302. A piston 301 is provided in the discharge tube 202, and the piston 301 is slidably connected to the discharge tube 202. The elastic member 302 is disposed in the discharge tube 202, and the elastic member 302 is disposed on a side of the piston 301 facing away from the accommodating chamber 101. The elastic member 302 can expand and contract along the first direction X to drive the piston 301 to move toward the feeding port 203. Alternatively, piston 301 may be a disk of a material having some elasticity, piston 301 being shaped to match the cross-sectional configuration of discharge tube 202, and piston 301 being sealingly connected to discharge tube 202. The elastic member 302 is a spring, one end of which abuts against the piston 301, and the other end of which abuts against the closed end of the discharge cylinder 202.

The sliding connection of piston 301 within discharge tube 202 provides a barrier or communication between inlet port 203 and outlet port 204. Acting as a barrier when piston 301 moves between inlet 203 and outlet 204, preventing uncontrolled discharge of material from outlet 204.

The elastic member 302 stretches and contracts in the first direction X, and can keep the piston 301 at a specific position above the discharge port 204 when no external force acts. The piston 301 can be quickly and accurately moved to the blocking position after the completion of the discharging, and simultaneously can provide a stable supporting force for the piston 301 during the feeding process, thereby preventing unexpected movement caused by material impact or vibration. Therefore, the risk of leakage of material from the discharge port 204 during the feeding process is reduced, and the stability and reliability of the whole system are improved.

Further, by precisely adjusting the strength and the expansion range of the elastic member 302, the control accuracy of the position of the piston 301 is improved, and the material can be accurately discharged from the discharge port 204 when reaching the preset condition.

In the above structure, the piston 301 and the elastic member 302 in the valve assembly 30 are designed to combine the functions of blocking, supporting and automatic control, so as to improve the precise control and stability of material feeding.

The limiting block 305 is disposed in the discharge tube 202, and the limiting block 305 is disposed between the discharge hole 204 and the supporting plate 303 to limit the movement of the supporting plate 303 towards the discharge hole 204.

A support plate 303 is provided within discharge tube 202 between piston 301 and resilient member 302. As a stable platform, it is capable of bearing the thrust from the piston 301 and transmitting such force to the underlying elastic member 302 or other fixed structure, improving the stability of the piston 301 during movement, the elastic member 302 being capable of operating smoothly when compressed or stretched, providing the necessary elasticity and return capability for the valve system.

The carrier rod 304 is mounted between the support plate 303 and the piston 301, forming a direct mechanical connection. When the piston 301 is externally driven, such as by pneumatic, hydraulic or mechanical forces, the force is transmitted to the support plate 303 via the ram 304, thereby controlling the flow of material. At the same time, the presence of the carrier rod 304 also enhances the strength of the connection between the piston 301 and the support plate 303, reducing the risk of loosening or failure due to vibration or shock.

The limiting block 305 is arranged between the discharge hole 204 and the supporting plate 303, and limits the maximum moving distance of the supporting plate 303 towards the discharge hole 204 in a physical manner, so that the maximum moving distance of the piston 301 connected with the ejector rod 304 towards the discharge hole 204 is limited, the unexpected removal of the piston 301 from the feed hole 203 during excessive movement is reduced, and the stability and reliability of the valve system under different working conditions are improved. By accurately designing the position and the size of the limiting block 305, the movement range of the piston 301 is accurately controlled, so that the stability and the control accuracy of the material feeding process are improved.

In the above-described structure, the cooperation among the support plate 303, the ejector rod 304 and the stopper 305 constitutes a core portion of the valve assembly 30. Together they improve the stability, accuracy and safety of the piston 301 during movement. Limiting block 305 is arranged to limit the moving range of supporting plate 303 and piston 301, so that the risk of piston 301 moving out of feed inlet 203 is reduced, and the controllability and reliability of the whole material feeding process are improved. This design allows the valve assembly 30 to operate stably under a variety of operating conditions and meets the precise control requirements for material flow and quality.

In some embodiments of the present application, the number of the jack rods 304 is plural, and the plurality of jack rods 304 are arranged at intervals along the circumferential direction of the piston 301.

As piston 301 moves within discharge tube 202, it may be subjected to forces from different directions, such as pressure, friction, and possibly vibration of the material. These forces, if not effectively balanced and supported, may cause the piston 301 to slosh or unstable during movement. By providing a plurality of carrier rods 304 and spacing them circumferentially around the piston 301, a uniform support network can be formed. This network is able to effectively disperse and balance the various forces acting on the piston 301, thereby ensuring that the piston 301 remains stationary and stable during movement.

In the design of the single jack 304, if the contact point of the jack 304 with the piston 301 is not on the central axis of the piston 301, or there is a deviation between the jack 304 and the piston 301 due to manufacturing, installation, etc., then tilting may occur during the movement of the piston 301. Such tilting may not only affect the smoothness of the material flow, but may also cause damage to the valve assembly 30. By employing a design in which a plurality of the jack rods 304 are arranged at intervals in the circumferential direction of the piston 301, it is ensured that each jack rod 304 can provide a uniform supporting force to the piston 301. Such uniform supporting force can effectively prevent the piston 301 from tilting during movement, thereby improving reliability and service life of the valve assembly 30.

In addition to improving the movement stability of the piston 301 and reducing the risk of tilting, the design of the plurality of carrier rods 304 spaced apart along the circumference of the piston 301 also improves the directional stability during movement of the piston 301. Since each of the carrier rods 304 is in close contact with the piston 301 and distributed along the circumferential direction thereof, they can collectively guide the piston 301 to move in a predetermined direction. The piston 301 can maintain accuracy of its moving direction even under the influence of external interference or internal friction, etc., so that the material flows in a desired manner.

As shown in fig. 4, in some embodiments of the present application, the quantitative discharging device 1 further includes a pushing assembly 50, and the pushing assembly 50 includes a driving plate 501 and a driving lever 502. The drive plate 501 is disposed in the accommodation chamber 101, and the drive plate 501 is disposed opposite to the quantitative push plate 201. The driving rod 502 is connected to a side of the driving plate 501 away from the quantitative push plate 201, and the driving rod 502 moves and drives the driving plate 501 to move along the first direction X, so as to push the material in the accommodating cavity 101 toward the direction of the discharge cylinder 202.

The drive plate 501 is arranged in the receiving chamber 101 and is arranged opposite the metering push plate 201, the drive plate 501 being able to act directly on the material in the receiving chamber 101. When the drive plate 501 is moved in the first direction X, i.e. towards the discharge vessel 202, it pushes the material towards the inlet of the discharge vessel 202, thereby initiating the discharge process of the material. The drive plate 501 may be designed to incorporate physical properties of the material, such as particle size, flowability, etc., so that it can effectively push the material without clogging or overcompression.

The drive rod 502 is a key component connecting the drive plate 501 with an external drive mechanism, which illustratively includes a motor or air cylinder, etc. One end of which is connected to the side of the drive plate 501 facing away from the quantitative push plate 201 and the other end is connected to the drive mechanism. When the driving mechanism is activated, it applies a pushing or pulling force to the driving plate 501 through the driving lever 502, thereby driving the driving plate 501 to move in a predetermined direction. This design allows an operator to indirectly control the movement of the drive plate 501 by controlling the drive mechanism, thereby achieving precise control of the material discharge process.

In the above-described structure, by providing the pushing assembly 50, the quantitative discharging device 1 can handle the material discharging task more efficiently. The direct pushing action of the drive plate 501 ensures a rapid and smooth transfer of material from the receiving chamber 101 into the discharge barrel 202. Meanwhile, the flexibility and controllability of the driving rod 502 enable an operator to adjust the speed and the amount of material discharge according to actual needs, so that different production requirements are met. In addition, the introduction of the pushing assembly 50 also simplifies the discharging process, reduces the dependence on manual operation, and improves the overall production efficiency and automation level.

In some embodiments of the present application, the pushing assembly 50 further includes a first drive motor 503, the first drive motor 503 being coupled to the drive rod 502. The first driving motor 503 may be a driving cylinder, for example.

And through carrying out accurate regulation to rotational speed, the steering and the moment of torsion of motor, can realize discharging speed and the accurate control of volume, satisfy different production demands.

In some embodiments of the present application, the quantitative discharging device 1 further comprises a scraping assembly 60, and the scraping assembly 60 comprises a scraping plate 601 and a scraping rod 602. The scraper 601 is disposed in the accommodating chamber 101, and the scraper 601 is disposed opposite to the discharge cylinder 202. The scraping rod 602 is connected to one side of the scraping plate 601 away from the discharge cylinder 202, and the scraping rod 602 moves and drives the scraping plate 601 to move towards the discharge cylinder 202, so as to extend the scraping plate 601 into the discharge cylinder 202 and push the material in the discharge cylinder 202 towards the direction of the discharge port 204.

Illustratively, the structure of the scraper 601 matches the structure of the common cross-section. Optionally, the scraping assembly 60 further includes a second sealing ring disposed between the scraping plate 601 and the discharge cylinder 202, and the second sealing ring is circumferentially disposed along the scraping plate 601.

The scraping assembly 60 mainly consists of a scraping plate 601 and a scraping rod 602. The scraper 601 is disposed in the accommodating chamber 101 as a portion directly contacting the material, and is disposed opposite to the discharge cylinder 202. The scraping plate 601 can contact the inner wall of the discharge cylinder 202, thereby effectively scraping off the material remaining thereon. The scraping rod 602 is connected to a side of the scraping plate 601 facing away from the discharge cylinder 202 as a power transmission member for driving the scraping plate 601 to move.

When it is desired to clean the residual material in the discharge barrel 202, the scraper bar 602 receives power from an external drive mechanism, such as a motor, cylinder or manual thrust, and moves in a predetermined direction. As the scraper bar 602 moves, it drives the scraper 601 towards the discharge cylinder 202 until the scraper 601 extends completely into the discharge cylinder 202. During this process, the scraping plate 601 slides against the inner wall of the discharge cylinder 202, scraping off the material attached thereto. The scraper 601 then continues to move axially along the discharge barrel 202 pushing scraped material in the direction of the discharge port 204. Finally, the material is smoothly discharged from the discharge port 204, and the whole cleaning process is completed.

In the above structure, the scraping plate 601 is arranged to clean the residual materials on the inner wall of the discharge cylinder 202 and discharge the materials from the discharge port 204, so that the accuracy of the material volume control is improved, and meanwhile, the material residues and waste are reduced.

In some embodiments of the present application, the driving plate 501 is concavely formed with a groove toward one side surface of the quantitative push plate 201, the groove being for accommodating the scraper 601.

The provision of the grooves creates a smooth transition region on the side facing the metering push plate 201, reducing the presence of protrusions or irregularities on the surface of the drive plate 501, thereby improving the overall flatness of the surface of the drive plate 501. The smooth surface of the driving plate 501 can reduce the friction resistance with the material when pushing the material, so that the material is easier to push, and the material moving efficiency is improved.

In some embodiments of the present application, the scraping assembly 60 further includes a second driving motor 603, and the second driving motor 603 is connected to the scraping bar 602. The second driving motor 603 may be a driving cylinder, for example.

The second driving motor 603 is used as a power source of the scraping assembly 60 to directly provide the linear motion power for the scraping rod 602. When the motor is started, it transmits power to the scraping rod 602, and thus drives the scraping plate 601 to move along the first direction X. The mechanized driving mode has higher efficiency and more stable performance compared with the traditional manual operation or simple mechanical device. The second driving motor 603 also indirectly improves the accuracy of the quantitative control by improving the efficiency of the scrap scraping. During the quantitative discharging process, if more material remains in the discharging barrel 202, the amount of the material actually discharged is affected in the next discharging process, thereby reducing the accuracy of quantitative control. And the second driving motor 603 can ensure that the residual materials in the discharging barrel 202 can be thoroughly scraped clean after each discharging, so that the accuracy of the material quantity in the next discharging process is improved.
