[0038] Combine Figures 1 to 5As shown, according to a specific embodiment of the present application, a feeding device is provided.

[0039] Specifically, if Figure 1 As shown, the feeding device includes: a box body 10 and a screw conveying mechanism 20. The box body 10 has a receiving chamber 11 and a discharge port 12. The screw conveying mechanism 20 is disposed in the receiving chamber 11. A material space is formed between the screw conveying mechanism 20 and the side wall of the receiving chamber 11. The discharge port 12 is connected to the material space. The screw conveying mechanism 20 has a working state of rotating about its own central axis to transport the material in the material space along the axial direction of the screw conveying mechanism 20 to the discharge port 12. Along the axial direction of the screw conveying mechanism 20, the pitch of at least part of the screw conveying mechanism 20 is arranged to gradually decrease.

[0040] In an embodiment of the present application, the feeding device includes: a box body 10 and a spiral conveying mechanism 20, and the box body 10 has a accommodating chamber 11 and a discharge port 12. The spiral conveying mechanism 20 is installed in the accommodating chamber 11, and a material space is formed between the spiral conveying mechanism 20 and the side wall of the accommodating chamber 11, and is connected to the space through the discharge port 12. When the spiral conveying mechanism 20 rotates, the material is pushed to move along the spiral shape of the spiral mechanism and gradually transported to the discharge port 12. Along the axial direction of the spiral conveying mechanism 20, the pitch of the spiral conveying mechanism 20 is gradually reduced. The design of gradually decreasing pitch can ensure that the material is subjected to more uniform thrust during the transportation process, reducing the risk of possible blockage or uneven transportation. The design of the above-mentioned feeding device effectively reduces the accumulation and blockage of materials, ensuring that the material is smoothly transported to the discharge port 12. While improving production efficiency, it ensures the stability and continuity of material transportation.

[0041] In an exemplary embodiment of the present application, the spiral conveying mechanism 20 has a first end close to the discharge port 12, and the spiral conveying mechanism 20 has a second end away from the discharge port 12. Along the direction from the second end to the first end, the pitch of at least part of the spiral conveying mechanism 20 is arranged to gradually decrease.

[0042] Specifically, the screw conveying mechanism 20 has a first end and a second end, wherein the first end is close to the discharge port 12 and the second end is farther away from the discharge port 12. The pitch of the screw conveying mechanism 20 gradually decreases from the second end to the first end. As the material moves toward the discharge port 12, the pitch needs to be gradually reduced to accommodate the material's propulsion requirements, thereby ensuring smooth and stable material delivery to the discharge port 12. This design ensures that the material receives a more uniform thrust during the conveying process, reducing the risk of possible blockage or uneven delivery, ensuring continuous and stable material delivery, and thus improving production efficiency.

[0043] Furthermore, the spiral conveying mechanism 20 has a first end close to the discharge port 12, and the spiral conveying mechanism 20 has a second end away from the discharge port 12. Along the direction from the second end to the first end, the outer diameter of at least part of the spiral conveying mechanism 20 is gradually reduced.

[0044] Specifically, the screw conveyor 20 is configured with a gradually decreasing outer diameter, with a first end proximal to the discharge port 12 and a second end distal to the discharge port 12. The outer diameter of the screw conveyor 20 gradually decreases from the second end toward the first end. This design primarily adjusts the outer diameter of the screw conveyor 20 based on changing material conveying requirements, ensuring uniform thrust during material conveyance and reducing the risk of possible blockage or uneven conveying. This design principle aims to adapt to changing material conveying requirements by improving conveying uniformity and efficiency through a gradually decreasing outer diameter.

[0045] Furthermore, the spiral conveying mechanism 20 includes a first conveying section 21 and a second conveying section 22. The first conveying section 21 is located on the side of the accommodating cavity 11 away from the discharge port 12. The first conveying section 21 is rotatably connected to the box body 10. One end of the second conveying section 22 is connected to the first conveying section 21, and the other end of the second conveying section 22 extends into the discharge port 12. The outer diameter of the first conveying section 21 remains unchanged along the direction from the second end to the first end, and the outer diameter of the second conveying section 22 is gradually reduced along the direction from the second end to the first end.

[0046] Specifically, if Figure 2 As shown, the design structure of the spiral conveying mechanism 20 includes a first conveying section 21 and a second conveying section 22, wherein the first conveying section 21 is located on the side of the accommodating chamber 11 away from the discharge port 12, and the second conveying section 22 extends into the discharge port 12. The outer diameter of the first conveying section 21 remains unchanged, while the outer diameter of the second conveying section 22 gradually decreases along the conveying direction to more evenly push the material toward the discharge port. Through this design, the first conveying section 21 remains stable, and the gradually decreasing outer diameter of the second conveying section 22 helps to ensure that the material is subjected to uniform thrust during the conveying process, reducing the risk of blockage or uneven conveying. Overall, this structural design effectively improves the stability and adaptability of the spiral conveying mechanism 20, ensures that the material is continuously and evenly conveyed to the discharge port 12, thereby improving production efficiency and reducing possible conveying problems, thereby improving the overall material conveying efficiency.

[0047] Furthermore, along the direction from the second end to the first end, the heights of the bottom planes of the box body 10 at positions corresponding to the first conveying section 21 are gradually increased.

[0048] Specifically, in this design, the bottom plane of the box body 10 gradually increases in height from the second end to the first end, corresponding to the location of the first conveying section 21. This provides more space for material conveying, reduces the risk of blockage, and ensures smooth material flow. This gradual increase in the bottom plane height improves conveying efficiency and stability, while maintaining a secure connection between the box body 10 and the first conveying section 21 and enhancing sealing. This design helps ensure continuous and stable material conveying, reduces the risk of blockage and obstruction, and improves production efficiency and reliability.

[0049] Furthermore, the discharge port 12 is protrudingly provided on a side wall of the box body 10 , a discharge channel is formed inside the discharge port 12 , and one end of the spiral conveying mechanism 20 close to the discharge port 12 extends into the discharge channel.

[0050] Specifically, the discharge port 12 protrudes from a side wall of the box body 10, forming a discharge channel within the box body. The end of the screw conveyor mechanism 20 near the discharge port 12 extends into the discharge channel. This design facilitates the smooth discharge of materials, allowing them to flow smoothly along the discharge channel and be effectively conveyed by the screw conveyor mechanism 20. Through this connection, the screw conveyor mechanism 20 can directly convey materials to the discharge port 12, improving the efficiency and smoothness of discharge, ensuring the continuity and stability of the production process, and thus improving overall production efficiency and quality.

[0051] Furthermore, the screw conveying mechanism 20 includes a screw 23 and blades 24 . The screw 23 is rotatably connected to the box body 10 . The blades 24 are spirally arranged on the outer peripheral surface of the screw 23 along the axial direction of the screw 23 .

[0052] Specifically, the screw conveying mechanism 20 consists of a screw 23 and blades 24, with the screw 23 being flexibly rotatably connected to the box body 10. The blades 24 are arranged spirally on the outer surface of the screw 23 along the axis. This design structure enables the screw conveying mechanism 20 to propel the material axially to the target location through the blades 24 as the screw 23 rotates. Through this mechanism, the screw conveying mechanism 20 can efficiently convey materials and ensure stable material transportation. This design not only improves conveying efficiency but also enhances the smoothness and stability of the production process.

[0053] In another embodiment of the present application, the screw 23 is a hollow rod-shaped structure with a through hole on the inner side. A plurality of ribs 231 are arranged at intervals along the circumferential direction on the inner side wall of the screw 23 , and the extension direction of the ribs 231 is parallel to the axial direction of the screw 23 .

[0054] Specifically, if Figure 4As shown, the screw 23 is a hollow rod-shaped structure with a through hole on the inner side, and a plurality of ribs 231 are arranged at intervals along the circumferential direction on the inner wall, and the extension direction of these ribs 231 is parallel to the axial direction of the screw 23. The function of this design structure is to increase the strength and stability of the screw 23, so that it can withstand greater torsional forces and pressures. By providing the ribs 231 on the inner wall of the screw 23, the screw 23 can be effectively prevented from being deformed or damaged during the conveying process, ensuring that it pushes the material stably. The parallel extension direction of the ribs 231 enables the screw 23 to transmit torque evenly during rotation, thereby improving the efficiency and stability of the conveying. Overall, this design helps to improve the service life and conveying performance of the screw 23, ensuring the smooth conveying of materials and the smooth progress of the production process.

[0055] Furthermore, the feeding device also includes an end cover 30. A mounting hole is provided on the other side wall of the box body 10 opposite to the side wall where the discharge port 12 is located. Part of the end cover 30 is located in the mounting hole, and the end cover 30 is detachably connected to the box body 10.

[0056] Specifically, the feeding device also includes an end cap 30, wherein a mounting hole is provided on the other side wall of the box body 10 at a position opposite the discharge port 12. A portion of the end cap 30 is installed in the mounting hole, and the end cap 30 can be detachably connected to the box body 10. Through the mounting hole and detachable connection, the end cap 30 can be easily removed to clean, maintain, or replace parts inside the feeding device. This not only facilitates maintenance work for operators, but also helps maintain the normal operation of the feeding device and extend the service life of the equipment. Therefore, the provision of the end cap 30 and the detachable connection design improve the ease of use and maintenance efficiency of the feeding device.

[0057] Furthermore, a sealing groove is provided on the outer peripheral surface of the portion of the end cover 30 located in the mounting hole, and a sealed space is formed between the hole wall of the mounting hole and the sealing groove, and a sealing member 70 is provided in the sealed space.

[0058] Specifically, a sealing groove is provided on the outer peripheral surface of the portion of the end cover 30 located in the mounting hole, and a sealed space is formed between the hole wall of the mounting hole and the sealing groove, and a sealing member 70 is provided in the sealed space. The function of this design structure is to ensure the sealing between the mounting hole and the end cover 30, and to prevent materials or liquids from leaking from the mounting hole. By providing a sealing groove and installing the sealing member 70, it is possible to effectively prevent external substances from entering the feeding device or internal materials from overflowing, thereby keeping the working environment of the feeding device clean and safe. This sealing design not only helps to protect the interior of the feeding device from external influences, but also reduces the entry of impurities, thereby improving the stability and reliability of the entire system. Therefore, the provision of the sealing groove and the sealing member 70 effectively improves the sealing performance and working efficiency of the feeding device.

[0059] Furthermore, the screw 23 is passed through the mounting hole and is located inside the end cover 30 . The feeding device further includes a limiting ring 40 . Along the radial direction of the screw 23 , the limiting ring 40 is located between the screw 23 and the end cover 30 .

[0060] Specifically, the screw 23 is passed through the mounting hole and is located on the inner side of the end cover 30. The limiting ring 40 is arranged along the radial direction of the screw 23 and is located between the screw 23 and the end cover 30. It limits the position of the screw 23 in the mounting hole and prevents it from excessive movement or swinging during operation. By setting the limiting ring 40, the position of the screw 23 in the mounting hole can be ensured to be stable, and unnecessary shaking or deviation of the screw 23 when conveying materials can be avoided, thereby ensuring the normal operation of the feeding device. The radial setting of the limiting ring 40 also helps to fix the distance between the screw 23 and the end cover 30, ensuring the stability and reliability of the entire device. Therefore, the setting of the limiting ring 40 effectively improves the working efficiency and safety of the feeding device.

[0061] Furthermore, a connecting portion is provided inside the end cover 30 , in which a magnetic body 50 is installed. The magnetic body 50 is in an adsorbed state with another magnetic structure on the installation base, so that the feeding device is connected to the installation base.

This design allows the feeding device to be conveniently connected to the installation base without the need for traditional fixed or bolted connection methods. Through the adsorption state of the magnetic body 50, the feeding device can be quickly and conveniently connected to or disassembled from the installation base structure, thereby improving the efficiency of installation and maintenance. This magnetic connection method not only simplifies the operating process, but also reduces the cost of installation and maintenance, while ensuring the reliability and stability of the connection. Therefore, the design of the magnetic body 50 effectively improves the installation convenience and use efficiency of the feeding device.

[0063] Furthermore, the feeding device further includes: a driving part, which is connected to the screw conveying mechanism 20 and is used to drive the screw conveying mechanism 20 to rotate along its own axis.

[0064] Specifically, the drive unit is connected to the spiral conveying mechanism 20 and is used to drive the spiral conveying mechanism 20 to rotate along its own axis. This means that the drive unit is responsible for providing power so that the spiral conveying mechanism 20 can rotate smoothly, thereby pushing the material to be transported along the axis of the spiral conveying mechanism 20. Through the connection between the drive unit and the spiral conveying mechanism 20, precise control and adjustment of the spiral conveying mechanism 20 can be achieved, ensuring that the material can be effectively and stably transported to the designated position. This design ensures the normal operation of the feeding device, improves production efficiency and the smoothness of the process.

[0066] Specifically, if Figure 3 As shown, the discharge nozzle assembly 60 is detachably connected to the discharge port 12 to guide the material discharged through the discharge port 12 to the target position. The design of the discharge nozzle assembly 60 allows it to be easily connected to or disassembled from the discharge port 12, thereby facilitating cleaning, maintenance or replacement. Through the discharge nozzle assembly 60, the flow direction of the material can be effectively controlled and guided to ensure that the material is smoothly transported to the target position. This design not only facilitates maintenance work for operators, but also helps to maintain the normal operation of the feeding device and extend the service life of the equipment. The setting of the discharge nozzle assembly 60 enables the material to be discharged to the target position accurately and orderly, improves the accuracy and stability of the feeding device, and thus improves production efficiency and quality.
