The discharging tube is connected to the quantitative push plate, and the discharging tube is provided with a feeding port and a discharging port, and the feeding port is connected to the receiving chamber. The valve assembly is arranged in the discharging tube, and the valve assembly is used to control the communication between the feeding port and the receiving chamber.

[0006] In the technical solution of the embodiment of the present application, the containing cylinder is used to contain materials for manufacturing batteries, and the materials can enter the containing cylinder from the feed port. The quantitative component is used to adjust the volume of the material in the containing cylinder. By moving the quantitative push plate in the containing cylinder to adjust the volume of the containing cylinder, the discharge cylinder can push the movement of the quantitative push plate, and the discharge cylinder is connected to the containing chamber and can also discharge the material in the containing cylinder from the discharge port, so as to achieve quantitative delivery of materials. The valve component is arranged in the discharge cylinder, which can control the opening and closing of the discharge cylinder. After the quantitative delivery of the material is completed, the valve component controls the discharge cylinder to open and release the material accurately, thereby improving the control efficiency and accuracy of the quantitative discharge of the material.

[0007] In some embodiments, the receiving tube is also provided with a discharge port. The receiving tube is provided with a discharge port, on the one hand, to discharge the air in the receiving tube when feeding at the feeding port, to maintain the air pressure balance in the receiving cavity, and to improve the efficiency of the feeding process. On the other hand, the discharge port can also discharge the excess material in time, to improve the accuracy of material quantification and the convenience of material control.

[0008] In some embodiments, the containing cylinder is provided with volume scale lines, which can directly observe the volume of the material in the containing cylinder, thereby improving the efficiency and convenience of material control.

The connecting block is connected to the discharge barrel, and a threaded hole is provided on the connecting block. The threaded rod is threadedly connected to the connecting block, and the threaded rod is arranged along the first direction. One end of the threaded rod is connected to the receiving barrel, and the rotation of the threaded rod drives the connecting block to move relative to the receiving barrel along the first direction. In the above structure, the connection of the discharge barrel is driven by setting a connecting block. One end of the threaded rod is connected to the receiving barrel, and the other end is threadedly connected to the connecting block. By rotating the threaded rod, the connecting block will move along the threaded rod, thereby driving the discharge barrel to move along the threaded rod. The threaded rod is connected to the receiving barrel to drive the discharge barrel to move relative to the receiving barrel. By rotating the threaded rod, the discharge barrel can be controlled to move relative to the receiving barrel along the first direction, thereby improving the efficiency and accuracy of the quantitative component control.

[0010] In some embodiments, the valve assembly includes a piston and an elastic member. The piston is disposed in the discharge barrel, and the piston is slidably connected to the discharge barrel. The elastic member is disposed in the discharge barrel, and the elastic member is disposed on the side of the piston away from the accommodating chamber. The elastic member can be retracted and retracted along a first direction to drive the piston to move toward the feed port. In the above structure, the piston can move in the discharge barrel, and when the piston moves between the feed port and the discharge port, the feed port and the discharge port are blocked, and the material cannot be discharged from the discharge port. When the piston moves below the discharge port, the feed port and the discharge port are connected, and the material can be discharged from the discharge port. By providing an elastic member, a supporting force is provided to the piston, and the piston is controlled above the discharge port, thereby reducing the risk of material leakage from the discharge port during the feeding process and improving the stability of the feeding process.

[0011] In some embodiments, the valve assembly further includes a support plate, a push rod, and a limit block. The support plate is disposed in the discharge barrel, and the support plate is disposed between the piston and the elastic member. The push rod is disposed between the support plate and the piston. The limit block is disposed in the discharge barrel, and the limit block is disposed between the discharge port and the support plate to limit the movement of the support plate toward the discharge port. In the above process, the movement of the support plate toward the discharge port is limited by setting the limit block, and the movement of the piston toward the accommodating chamber is also limited, thereby reducing the risk of the piston moving out of the feed port and improving the stability of the material feeding process and the accuracy of control.

[0012] In some embodiments, there are multiple push rods, and the multiple push rods are arranged at intervals along the circumference of the piston. The multiple push rods improve the stability of the piston during movement. The multiple push rods are arranged along the circumference of the piston to reduce the risk of the piston tilting and improve the directional stability of the piston during movement.

[0013] In some embodiments, the quantitative discharging device further includes a pushing assembly, which includes a driving plate and a driving rod. The driving plate is disposed in the accommodating chamber, and the driving plate and the pushing plate are disposed opposite to each other. The driving rod is connected to the side of the driving plate away from the quantitative pushing plate, and the driving rod moves and drives the driving plate to move along a first direction to push the material in the accommodating chamber toward the direction of the discharging cylinder. In the above structure, the driving plate is arranged to push the material in the accommodating cylinder and discharge the material from the accommodating cylinder, and the driving rod can drive the driving plate to move, which is convenient for operation and improves the discharging efficiency.

[0014] In some embodiments, the pusher assembly further comprises a first drive motor, and the first drive motor is connected to the drive rod. By providing the first drive motor, the efficiency of discharging is improved.

[0015] In some embodiments, the quantitative discharging device further includes a scraper assembly, which includes a scraper plate and a scraper rod. The scraper plate is disposed in the accommodating cavity, and the scraper plate is disposed opposite to the discharging barrel. The scraper rod is connected to the side of the scraper plate away from the discharging barrel, and the scraper rod moves and drives the scraper plate to move toward the discharging barrel, so that the scraper plate is extended into the discharging barrel and the material in the discharging barrel is pushed toward the discharge port.

[0016] In the above structure, the scraper plate is provided to clean the residual material on the inner wall of the discharge barrel and discharge it from the discharge port, thereby improving the accuracy of material volume control and reducing material residue and waste.

It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0039] In the production process of batteries, the quality of raw materials needs to be precisely controlled to ensure the qualified rate of products and improve production efficiency. Existing devices for controlling raw materials usually include a tank body with a discharge port. The discharge port is connected to a material pipe, and a solenoid valve for controlling the opening or closing of the discharge pipe is provided on the material pipe. The quality of the raw materials fed is controlled by controlling the opening and closing of the solenoid valve.

[0040] However, although the volume of material released can be roughly controlled by controlling the opening and closing of the solenoid valve, the flow rate cannot be accurately controlled, the precise quality of the material cannot be guaranteed, and the accuracy of quality control required by the existing production process cannot be met, which often results in large material delivery errors and reduced product qualification rates.

[0041] Based on the above problems, an embodiment of the present application provides a quantitative discharging device, in which a receiving cylinder is provided for accommodating materials for manufacturing batteries, and the materials can enter the receiving cylinder from the feed port. The quantitative component is used to adjust the volume of the material in the receiving cylinder. The volume of the receiving cylinder is adjusted by moving the quantitative push plate in the receiving cylinder. The discharging cylinder can push the movement of the quantitative push plate, and the discharging cylinder is connected to the accommodating chamber and can also discharge the material in the accommodating cylinder from the discharge port, so as to accurately control the quantitative delivery of the materials. The valve assembly is arranged in the discharging cylinder, and can control the opening and closing of the discharging cylinder. After the quantitative delivery of the materials is completed, the valve assembly controls the opening of the discharging cylinder to accurately release the materials, thereby improving the control efficiency and accuracy of the quantitative discharge of the materials.

[0042] Please refer to Figures 1 to 2 , Figure 1 This is a schematic diagram of the structure of a quantitative discharging device provided in some embodiments of the present application. Figure 2 A schematic diagram of the structure of a quantitative discharging device provided in some other embodiments of the present application.

[0043] As shown in the figure, the quantitative discharging device 1 provided in the embodiment of the present application includes a receiving tube 10, a quantitative component 20 and a valve component 30. The receiving tube 10 has a receiving chamber 101, and the receiving tube 10 is provided with a feed port 102 connected to the receiving chamber 101. The quantitative component 20 includes a quantitative push plate 201 and a discharging tube 202, and the quantitative push plate 201 is arranged in the receiving chamber 101 and is slidably connected to the receiving tube 10. The discharging tube 202 is connected to the quantitative push plate 201, and the discharging tube 202 is provided with a feed port 203 and a discharge port 204, and the feed port 203 is connected to the receiving chamber 101. The valve component 30 is arranged in the discharging tube 202, and the valve component 30 is used to control the communication between the feed port 203 and the receiving chamber 101.

[0044] The quantitative discharging device 1 described above can be used for the quantitative delivery of various materials in the battery production process. For example, it can be used for the quantitative delivery of positive and negative active materials on electrode plates, the quantitative delivery of conductive agents, the quantitative delivery of electrolytes in electrolytes, etc. It is understandable that, in addition to the battery production process, other production processes that require precise quantitative delivery can adopt the quantitative discharging device 1 provided in the embodiment of the present application, and no limitation is made here.

[0045] Optionally, the accommodating cylinder 10 has a cylindrical accommodating chamber 101, which is convenient for the flow and cleaning of materials. One end of the accommodating cylinder 10 can be closed to reduce the risk of impurities entering the accommodating chamber 101. A feed port 102 is provided on the side wall of the accommodating cylinder 10, and the feed port 102 can be connected to a feed pipe to facilitate the entry of materials into the accommodating cylinder 10. The other end of the accommodating cylinder 10 is provided with an opening, and is connected to a discharge cylinder 202, which is sealed and connected to the accommodating cylinder 10 to reduce the risk of material leakage.

[0046] The quantitative push plate 201 is disposed in the accommodating tube 10. The shape of the quantitative push plate 201 can be similar to the cross section of the accommodating chamber 101. For example, the quantitative push plate 201 is a circular or elliptical structure. The edge of the quantitative push plate 201 is attached to and sealed with the inner wall of the accommodating tube 10, which facilitates the movement of the quantitative push plate 201 in the accommodating tube 10 and reduces the residual material on the inner wall of the accommodating tube 10.

[0047] The quantitative push plate 201 is provided with a through hole, and one end of the discharge barrel 202 passes through the through hole and is connected to the quantitative push plate to drive the quantitative push plate 201 to move in the accommodating chamber 101. The other end of the discharge barrel 202 is closed to improve the sealing performance of the discharge barrel 202 and reduce the risk of material leakage. The feed port 203 of the discharge barrel 202 is set at one end facing the quantitative push plate 201, and the discharge port 204 is set on the side wall of the discharge barrel 202, and the discharge port 204 is set outside the accommodating barrel 10. The discharge barrel 202 has a material flow channel, and the material flow channel connects the feed port 203 and the discharge port 204.

[0048] The valve assembly 30 may be a piston 301 assembly or a ball valve assembly, etc. The valve assembly 30 is disposed in the sealing cavity to connect or block the feed port 203 and the discharge port 204 .

[0049] In the technical solution of the embodiment of the present application, the containing cylinder 10 is used to contain materials for manufacturing batteries, and the materials can enter the containing cylinder 10 from the feed port 102. The quantitative component 20 is used to adjust the volume of the material in the containing cylinder 10. By moving the quantitative push plate 201 in the containing cylinder 10 to adjust the volume of the containing cylinder 10, the discharge cylinder 202 can push the movement of the quantitative push plate 201, and the discharge cylinder 202 is connected to the containing chamber 101 and can also discharge the material in the containing cylinder 10 from the discharge port 204, so as to achieve quantitative delivery of materials. The valve component 30 is arranged in the discharge cylinder 202, and can control the opening and closing of the discharge cylinder 202. After the quantitative delivery of the materials is completed, the valve component 30 controls the discharge cylinder 202 to open and accurately release the materials, thereby improving the control efficiency and accuracy of the quantitative discharge of the materials.

[0050] In some optional embodiments, a first sealing ring is provided between the quantitative push plate 201 and the accommodating tube 10, and the first sealing ring is arranged around the circumference of the quantitative push plate 201. The above structure improves the sealing performance between the quantitative push plate 201 and the accommodating tube 10. In addition, during the movement of the quantitative push plate 201, the material remaining on the inner wall of the accommodating tube 10 can be scraped, reducing the material residue and improving the efficiency of material delivery.

[0051] In some embodiments of the present application, a discharge port 103 is further provided on the accommodating cylinder 10. Exemplarily, the discharge port 103 is provided on the side wall of the accommodating cylinder 10, and the discharge port 103 is substantially opposite to the feed port 102. The upper end of the discharge port 103 is lower than the lower end of the feed port 102, which is convenient for the discharge of materials.

[0052] In the above structure, during the feeding process, as the material continues to enter the containing tube 10, the air pressure in the tube will gradually increase. If the air is not exhausted in time, the feeding speed will be reduced, and even the material will block the feeding port 102. By providing a discharge port 103 on the containing tube 10, the gas in the tube can be discharged at the same time when feeding, and the air pressure in the containing chamber 101 can be kept balanced, thereby ensuring that the material can enter smoothly and quickly, thereby improving the efficiency of the feeding process. Alternatively, due to factors such as material properties, feeding speed or operating errors, the amount of material in the containing tube 10 may exceed the preset quantitative value. If these excess materials are not discharged in time, the quality and consistency of the final product will be affected.

[0053] By setting the discharge port 103, the excess material can be discharged in time during the process of adjusting the material volume in the quantitative component 20, thereby ensuring the accuracy of the material quantification. In actual applications, the demand and type of materials may change with the adjustment of the production plan. By setting the discharge port 103, the operator can flexibly adjust the input and discharge amounts of materials according to actual needs, thereby improving the convenience and flexibility of material control. During the use of the equipment, some residues or impurities may be generated. By setting the discharge port 103, these residues or impurities can be easily discharged, reducing the difficulty and cost of equipment cleaning and maintenance.

[0054] In some embodiments of the present application, volume scale lines are provided on the containing tube 10. Optionally, the containing tube 10 is made of metal materials such as stainless steel or aluminum alloy, and the volume scale lines can be concave-convex structures formed on the wall of the containing tube 10, or the containing tube 10 is made of high-strength glass, which can facilitate observation of the internal situation of the containing tube 10 and marking of scale lines on the containing tube 10. The precise mass of the material can be obtained by converting the volume with the density of the known material.

[0055] In the above structure, by clearly marking the volume scale lines on the outer wall of the containing cylinder 10, the operator can quickly and accurately determine the volume of the material in the cylinder. This intuitiveness eliminates the cumbersome process that may require the use of other measuring tools or estimates in traditional methods, thereby improving work efficiency. The volume scale lines are usually precisely designed and calibrated to improve the accuracy of the corresponding volume readings at different liquid levels. When adding or removing materials, the operator only needs to simply observe the scale lines to grasp the current material volume, without interrupting the workflow for additional measurements, making the operation process more convenient and efficient. Since the accuracy and efficiency of material control are improved, waste and losses caused by excessive or insufficient addition of materials can be reduced, which helps to reduce production costs and improve economic benefits.

[0056] like Figure 2 As shown, in some embodiments of the present application, the discharge barrel 202 and the receiving barrel 10 are arranged along the first direction X, and the quantitative discharge device 1 further includes a moving assembly 40, and the moving assembly 40 includes a connecting block 401 and a threaded rod 402. The connecting block 401 is connected to the discharge barrel 202, and a threaded hole is provided on the connecting block 401. The threaded rod 402 is threadedly connected to the connecting block 401, and the threaded rod 402 is arranged along the first direction X. One end of the threaded rod 402 is connected to the receiving barrel 10, and the threaded rod 402 rotates to drive the connecting block 401 to move relative to the receiving barrel 10 along the first direction X.

[0057] Exemplarily, the connection block 401 is a block-shaped entity and can be made of metal, high-strength organic material, etc. One end of the threaded rod 402 can be threadedly connected to the accommodating tube 10 . The first direction X can be the axial direction of the accommodating tube 10 .

[0058] The connection block 401 is used as an intermediate medium and is firmly connected to the discharge cylinder 202. A threaded hole is provided on the connection block 401, which provides accurate positioning and firm support for the threaded rod 402. The threaded rod 402 is designed to be arranged along a first direction X, which may be a vertical direction perpendicular to a horizontal plane. One end of the threaded rod 402 is connected to the receiving cylinder 10, and the other end is tightly matched with the connection block 401 through a thread.

[0059] When the position of the discharge barrel 202 needs to be adjusted to control the discharge of the material, the operator only needs to rotate the threaded rod 402. Due to the self-locking characteristics and precise fit of the thread, the rotation of the threaded rod 402 will drive the connecting block 401 to move along the direction of the threaded rod 402. Since the connecting block 401 is connected to the discharge barrel 202, the discharge barrel 202 will also move accordingly, thereby achieving precise adjustment of the material discharge amount.

[0060] The above technical solution allows operators to achieve precise control of material discharge through simple mechanical operations without direct contact with the material. 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 component can maintain good performance and accuracy during long-term use.

[0061] In some embodiments of the present application, the valve assembly 30 includes a piston 301 and an elastic member 302. The piston 301 is disposed in the discharge barrel 202, and the piston 301 is slidably connected to the discharge barrel 202. The elastic member 302 is disposed in the discharge barrel 202, and the elastic member 302 is disposed on the side of the piston 301 away from the accommodating chamber 101. The elastic member 302 can be retracted along the first direction X to drive the piston 301 to move toward the feed port 203. Optionally, the piston 301 can be a disc-shaped object made of a material with a certain elasticity, the shape of the piston 301 matches the cross-sectional structure of the discharge barrel 202, and the piston 301 is sealed and connected to the discharge barrel 202. The elastic member 302 is a spring, one end of the spring abuts against the piston 301, and the other end of the spring abuts against the closed end of the discharge barrel 202.

[0062] The piston 301 is slidably connected in the discharge barrel 202 to block or communicate between the feed port 203 and the discharge port 204. When the piston 301 moves between the feed port 203 and the discharge port 204, it acts as a barrier to prevent the material from being discharged from the discharge port 204 without control.

[0063] The elastic member 302 is retracted along the first direction X, and can keep the piston 301 at a specific position above the discharge port 204 when no external force is applied. The piston 301 can quickly and accurately move to the blocking position after the discharge is completed, and can provide a stable support force for the piston 301 during the feeding process to prevent accidental movement caused by material impact or vibration. Therefore, the risk of material leakage from the discharge port 204 during the feeding process is reduced, and the stability and reliability of the entire system are improved.

[0064] Furthermore, by precisely adjusting the strength and telescopic 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 the preset conditions are met.

[0065] 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, thereby improving the precise controllability and stability of material delivery.

[0066] like Figure 3In some embodiments of the present application, the valve assembly 30 further includes a support plate 303, a push rod 304 and a stop block 305. The support plate 303 is disposed in the discharge barrel 202, and the support plate 303 is disposed between the piston 301 and the elastic member 302. The push rod 304 is disposed between the support plate 303 and the piston 301. The stop block 305 is disposed in the discharge barrel 202, and the stop block 305 is disposed between the discharge port 204 and the support plate 303 to limit the movement of the support plate 303 toward the discharge port 204.

[0067] The support plate 303 is arranged in the discharge barrel 202, between the piston 301 and the elastic member 302. As a stable platform, it can withstand the thrust from the piston 301 and transmit this force to the elastic member 302 or other fixed structure below, thereby improving the stability of the piston 301 during movement. The elastic member 302 can work smoothly when compressed or stretched, providing the necessary elasticity and reset ability for the valve system.

[0068] The push rod 304 is installed between the support plate 303 and the piston 301, forming a direct mechanical connection. When the piston 301 is driven by an external force, such as air pressure, hydraulic pressure or mechanical force, the force is transmitted to the support plate 303 through the push rod 304, thereby controlling the flow of the material. At the same time, the presence of the push rod 304 also enhances the connection strength between the piston 301 and the support plate 303, reducing the risk of loosening or failure due to vibration or impact.

[0069] The limit block 305 is arranged between the discharge port 204 and the support plate 303, and physically limits the maximum moving distance of the support plate 303 toward the discharge port 204, thereby limiting the maximum moving distance of the piston 301 connected to the ejector rod 304 toward the discharge port 204, reducing the accidental movement of the piston 301 from the feed port 203 during excessive movement, and also improving the stability and reliability of the valve system under different working conditions. By accurately designing the position and size of the limit block 305, the movement range of the piston 301 is accurately controlled, thereby improving the stability of the material feeding process and the accuracy of control.

[0070] In the above structure, the cooperation between the support plate 303, the push rod 304 and the stop block 305 constitutes the core part of the valve assembly 30. Together, they improve the stability, accuracy and safety of the piston 301 during movement. By setting the stop block 305 to limit the movement range of the support plate 303 and the piston 301, not only the risk of the piston 301 moving out of the feed port 203 is reduced, but also the controllability and reliability of the entire material feeding process are improved. This design enables the valve assembly 30 to operate stably under various working conditions and meet the requirements for precise control of material flow and quality.

[0071] In some embodiments of the present application, there are multiple push rods 304 , and the multiple push rods 304 are arranged at intervals along the circumference of the piston 301 .

[0072] When the piston 301 moves in the discharge barrel 202, it may be subjected to forces from different directions, such as pressure, friction and possible vibration of the material. If these forces are not effectively balanced and supported, the piston 301 may be shaken or unstable during the movement. By providing multiple push rods 304 and distributing them at intervals along the circumference of the piston 301, a uniform support network can be formed. This network can effectively disperse and balance the various forces acting on the piston 301, thereby ensuring that the piston 301 remains stable and stable during the movement.

[0073] In the design of a single push rod 304, if the contact point between the push rod 304 and the piston 301 is not on the central axis of the piston 301, or there is a deviation between the push rod 304 and the piston 301 due to manufacturing, installation and other reasons, the piston 301 may tilt during its movement. This tilt not only affects the smoothness of material flow, but also may damage the valve assembly 30. By adopting a design in which multiple push rods 304 are arranged at intervals along the circumference of the piston 301, it can be ensured that each push rod 304 can provide uniform support force to the piston 301. This uniform support force can effectively prevent the piston 301 from tilting during movement, thereby improving the reliability and service life of the valve assembly 30.

[0074] In addition to improving the movement stability of the piston 301 and reducing the risk of tilting, the design of multiple push rods 304 arranged at intervals along the circumference of the piston 301 can also improve the directional stability of the piston 301 during movement. Since each push rod 304 is in close contact with the piston 301 and distributed along its circumference, they can jointly guide the piston 301 to move in a predetermined direction. Even under the influence of external interference or internal friction, the piston 301 can maintain the accuracy of its moving direction so that the material flows in the expected manner.

[0075] like Figure 4 As shown, 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 rod 502. The driving plate 501 is disposed in the accommodating chamber 101, and the driving plate 501 is disposed opposite to the quantitative pushing plate 201. The driving rod 502 is connected to a side of the driving plate 501 away from the quantitative pushing 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 chamber 101 toward the direction of the discharging cylinder 202.

[0076] The driving plate 501 is disposed in the accommodating chamber 101 and is disposed opposite to the quantitative push plate 201. The driving plate 501 can directly act on the material in the accommodating chamber 101. When the driving plate 501 moves along the first direction X, that is, toward the discharge barrel 202, it pushes the material toward the inlet of the discharge barrel 202, thereby starting the material discharge process. The design of the driving plate 501 can be combined with the physical properties of the material, such as particle size, fluidity, etc., so that it can effectively push the material without causing blockage or excessive compression.

[0077] The driving rod 502 is a key component connecting the driving plate 501 and the external driving mechanism. Exemplarily, the external driving mechanism includes a motor or a cylinder. One end of the driving rod 502 is connected to the side of the driving plate 501 away from the quantitative push plate 201, and the other end is connected to the driving mechanism. When the driving mechanism is started, it will apply a thrust or a pull to the driving plate 501 through the driving rod 502, thereby driving the driving plate 501 to move in a predetermined direction. This design allows the operator to indirectly control the movement of the driving plate 501 by controlling the driving mechanism, thereby achieving precise control of the material discharge process.

[0078] In the above structure, by providing the push assembly 50, the quantitative discharge device 1 can handle the material discharge task more efficiently. The direct pushing action of the drive plate 501 ensures that the material can be quickly and smoothly transferred from the accommodating chamber 101 to the discharge cylinder 202. At the same time, the flexibility and controllability of the drive rod 502 allow the operator to adjust the speed and amount of material discharge according to actual needs, thereby meeting different production needs. In addition, the introduction of the push assembly 50 also simplifies the discharge process, reduces the dependence on manual operation, and improves the overall production efficiency and automation level.

[0079] In some embodiments of the present application, the pusher assembly 50 further includes a first drive motor 503, and the first drive motor 503 is connected to the drive rod 502. Exemplarily, the first drive motor 503 may be a drive cylinder.

[0080] By setting the first drive motor 503, the discharge process is automatically controlled. The operator only needs to start the motor through the control panel or remote control system to realize the automatic discharge of the material, which reduces the labor intensity and improves the work efficiency. The first drive motor 503 can also provide continuous and stable power output to ensure that the drive rod 502 has sufficient thrust and speed when pushing the material, quickly discharges the material from the accommodating chamber 101, reduces the discharge time, and improves production efficiency. In addition, by accurately adjusting the speed, direction and torque of the motor, the discharge speed and amount can be accurately controlled to meet different production needs.

[0081] In some embodiments of the present application, the quantitative discharging device 1 further includes a scraper assembly 60, and the scraper assembly 60 includes a scraper plate 601 and a scraper rod 602. The scraper plate 601 is disposed in the accommodating chamber 101, and the scraper plate 601 is disposed opposite to the discharging barrel 202. The scraper rod 602 is connected to the side of the scraper plate 601 away from the discharging barrel 202, and the scraper rod 602 moves and drives the scraper plate 601 to move toward the discharging barrel 202, so as to extend the scraper plate 601 into the discharging barrel 202 and push the material in the discharging barrel 202 toward the direction of the discharge port 204.

[0082] Exemplarily, the structure of the scraper plate 601 matches the structure of the cross section of the scraper. Optionally, the scraper assembly 60 further includes a second sealing ring disposed between the scraper plate 601 and the discharge barrel 202 , and the second sealing ring is disposed around the scraper plate 601 circumferentially.

[0083] The scraper assembly 60 mainly consists of a scraper plate 601 and a scraper rod 602. The scraper plate 601, as the part that directly contacts the material, is arranged in the accommodating chamber 101 and is opposite to the discharge barrel 202. The scraper plate 601 can contact the inner wall of the discharge barrel 202, thereby effectively scraping off the material remaining on it. The scraper rod 602 is connected to the side of the scraper plate 601 away from the discharge barrel 202, and serves as a power transmission component for driving the scraper plate 601 to move.

[0084] When it is necessary to clean the residual material in the discharge barrel 202, the scraper rod 602 receives power from an external driving mechanism, such as a motor, a cylinder or manual thrust, and moves in a predetermined direction. As the scraper rod 602 moves, it drives the scraper plate 601 to move toward the discharge barrel 202 until the scraper plate 601 is fully inserted into the discharge barrel 202. In this process, the scraper plate 601 slides against the inner wall of the discharge barrel 202 and scrapes off the material attached thereto. Subsequently, the scraper plate 601 continues to move along the axial direction of the discharge barrel 202 and pushes the scraped material toward the discharge port 204. Finally, the material is discharged smoothly from the discharge port 204, completing the entire cleaning process.

[0085] In the above structure, the scraper plate 601 is provided to clean the residual material on the inner wall of the discharge barrel 202 and discharge it from the discharge port 204, thereby improving the accuracy of material volume control and reducing material residue and waste.

[0086] In some embodiments of the present application, a surface of one side of the driving plate 501 facing the quantitative push plate 201 is concave to form a groove, and the groove is used to accommodate the scraper plate 601 .

[0087] The groove is arranged on the side facing the quantitative push plate 201 to form a smooth transition area, which reduces the protrusions or uneven parts that may exist on the surface of the driving plate 501, thereby improving the overall flatness of the surface of the driving plate 501. The flat surface of the driving plate 501 can reduce the friction resistance with the material when pushing the material, making the material easier to be pushed, thereby improving the efficiency of material movement.

[0088] In some embodiments of the present application, the scraper assembly 60 further includes a second drive motor 603, and the second drive motor 603 is connected to the scraper rod 602. Exemplarily, the second drive motor 603 may be a drive cylinder.

[0089] The second drive motor 603 serves as the power source of the scraper assembly 60, and directly provides power for the scraper rod 602 to move in a straight line. When the motor is started, it transmits power to the scraper rod 602, thereby driving the scraper plate 601 to move along the first direction X. This mechanized driving method has higher efficiency and more stable performance than traditional manual operation or simple mechanical devices. By improving the efficiency of scraping off residual materials, the second drive motor 603 also indirectly improves the accuracy of quantitative control. During the quantitative discharge process, if there is a lot of material remaining in the discharge barrel 202, the actual amount of material discharged will be affected during the next discharge, thereby reducing the accuracy of quantitative control. The second drive motor 603 can ensure that the residual material in the discharge barrel 202 can be thoroughly scraped off after each discharge, thereby improving the accuracy of the material amount during the next discharge.
