Description

Technical Field

[0001] This invention relates to the field of thin film processing technology, specifically to a raw material conveyor for thin film processing. Background Technology

[0002] Film serves a protective packaging function, isolating oxygen, moisture, and microorganisms, thus extending the shelf life of food. It also provides cushioning and scratch protection, safeguarding the appearance and performance of electronic components, hardware, and other products. Films are widely used in packaging, agriculture, electronics, optics, and medical fields. High-molecular-weight resin granules are a crucial raw material in film production. The material and properties of these granules directly determine the film's basic mechanical properties, functionality, and applicable scenarios. The transportation of film raw materials takes place in automated storage and retrieval systems (AS / RS). These AS / RS are intelligent storage units for high-level storage of the resin granules, enabling automated inbound and outbound scheduling and ensuring orderly management and on-demand supply of raw materials. Screw conveyors connect the AS / RS to downstream processing equipment, serving as a material transport link between the AS / RS and external production lines or processes. They are a core device for achieving automated and continuous material transport in production lines, as illustrated by Chinese utility model patent application number 202223333024.8, filed on December 13, 2022. The first patent application, a screw conveyor, describes a screw conveyor whose operation involves controlling the rotation of the conveyor body along a shaft by retracting and extending ropes. This allows for adjustment of the conveying angle, facilitating connection to different equipment, simplifying assembly and adjustment, and offering greater flexibility and wide applicability. The second patent application, a Chinese utility model patent application (application number 202222379283.8, application date 2022-09-07), also describes a screw conveyor. Compared to traditional screw conveyors, it adds an air-assisted nozzle to the casing, enabling the conveyor to purge the material transport chamber. This effectively solves the technical problem of residual material between the casing and the screw blades, achieving fully automatic cleaning of the conveyor's interior, eliminating material mixing during product switching, and improving switching efficiency and product quality. Finally, the third patent application, a Chinese invention patent application (application number 202511308274.1, application date 2025-09-15), also describes a screw conveyor that solves the technical problem of solid-liquid separation and clogging when conveying high-viscosity materials. When a screw conveyor transports polymer resin particles, if the polymer resin particles clump together and the machine body is not equipped with an anti-clumping structure, it will lead to uneven feeding of the screw conveyor, fluctuations in machine speed, decreased quantitative conveying accuracy, and even material blockage and shutdown. Moreover, it will disrupt the material scheduling rhythm of automated warehouses and production lines. Therefore, we propose a raw material conveyor for film processing to solve the above-mentioned problems. Summary of the Invention

[0005] Preferably, the reversing component includes a fixed rod fixedly connected to the end of the long pin, and the surface of the fixed rod is provided with a guide groove, which is annular and wavy, and the long pin is connected to the working rod by a pulley.

[0006] Preferably, a limiting rod is fixedly connected to the inner wall of the hopper, and the end of the limiting rod is protruding. A movable plate is slidably provided on the surface of the limiting rod. A guide rod is fixedly connected to the inner wall of the movable plate, and the end of the guide rod is bent and located inside the guide groove.

[0007] Preferably, a rack is fixedly connected to the outer wall of the movable plate, a gear that meshes with the rack is fixedly connected to the surface of the connecting shaft, and a limit groove is opened inside the connecting shaft. Limiting blocks corresponding to the limit grooves are fixedly connected to both the left and right sides of the inner rod.

[0008] Preferably, the lifting component includes a connecting spring fixedly connected to the inner wall of the connecting shaft, and the other side of the connecting spring is fixedly connected to the end of the inner rod. A force-bearing block is fixedly connected to the upper surface of the long plate, and the striking rods are distributed at equal angles on the surface of the inner rod.

[0009] Preferably, a pushing block is fixedly connected to the lower surface of the inner plate, and the end of the pushing block and the end of the force-receiving block are both arc-shaped structures, and the pushing blocks are distributed at equal angles on the lower surface of the inner plate.

[0010] Preferably, the auxiliary barrel is a hollow frustum shape, the working plate is a frustum shape, and the surface of the working plate is provided with extrusion blocks at equal intervals, and the working plate is located inside the auxiliary barrel.

[0011] Preferably, the upper surface of the long plate is raised, the reciprocating component includes a return spring fixedly connected to the raised position on the upper surface of the long plate, and the other side of the return spring is fixedly connected to the inner wall of the wiping plate, and magnets are provided on the outer wall of the wiping plate and the inner wall of the hopper.

[0012] Preferably, the magnets are distributed at equal angles on the inner wall of the hopper, and the end magnetic poles of the magnets on the surface of the wiping plate are the same as the end magnetic poles of the magnets on the inner wall of the hopper.

[0013] Preferably, the surface of the airbag is in contact with the surface of the movable plate, and an air inlet pipe is fixedly connected to the upper surface of the airbag, and the lower surface of the airbag is connected to the inner rod through an air delivery hose, and a one-way valve is provided on the surface of the air delivery hose and the surface of the air inlet pipe, and nozzles are opened at equal angles on the surface of the working plate.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: Adopting a novel structural design, during operation, raw materials are fed into the hopper through the inlet. While the motor is running, the striking rod reciprocates inside the hopper, effectively breaking up the particles. Furthermore, the working plate is also in a multi-dimensional compression state of the particles, providing a secondary breaking-up effect. Consequently, the machine body has a multi-layered anti-caking structure, which does not affect the normal conveying of raw materials, improves work efficiency, and ensures the material scheduling rhythm of the automated warehouse and production line. The specific details are as follows: This film processing raw material conveyor feeds raw materials into the hopper through the feed inlet during operation. Then, the motor is started, and the motor drives the working rod and auger to complete the spiral conveying. While the motor is working, the connecting shaft and the striking rod will reciprocate inside the inner plate. The striking rod plays the role of breaking up the particles, thereby preventing the particles from clumping.

[0015] When the connecting shaft, inner rod, and long plate of this film processing raw material conveyor rotate, the inner rod drives the wiping plate and magnet to rotate synchronously. As the wiping plate rotates, it also makes a reciprocating linear motion on the surface of the long plate. The surface of the wiping plate is equipped with brushes. When the wiping plate works in multiple dimensions, it plays a role in preventing residue.

[0016] In this raw material conveyor for film processing, the inner rod rotates synchronously with the connecting shaft during operation. Simultaneously, under the action of the pushing block, the force-bearing block, and the connecting spring, it makes a reciprocating linear motion in the vertical direction. Consequently, the working plate and the extrusion block intermittently extrude the raw material. At this time, the working plate plays a secondary role in preventing agglomeration.

[0017] This raw material conveyor for film processing intermittently compresses the air bladder when the movable plate reciprocates in a horizontal linear motion. The air bladder then intermittently supplies air to the working plate and nozzles through the inner rod. At this time, the intermittent air jets from the nozzles can precisely impact the compressed particle clusters, break up agglomerates, and destroy the adhesion between particles, thus enhancing the anti-caking effect. At the same time, it blows the inner wall of the auxiliary barrel to remove adhering particles, remove frictional heat, and prevent material blockage and equipment overload.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-12 The present invention provides the following technical solution: a raw material conveyor for thin film processing.

[0022] Example 1: By using a reversing component, the connecting shaft 7 and the inner rod 9 can reciprocate inside the hopper 4, thereby enabling the striking rod 10 to strike and prevent clumping. Figures 1-7 as well as Figure 12 As shown, the machine includes a body 1, a motor 2 bolted to the side of the body 1, a working rod at the output end of the motor 2, a conveying auger on the working rod, and a discharge port at the end of the body 1; an auxiliary barrel 3 fixedly connected to the upper surface of the body 1, a discharge hopper 4 fixedly connected to the upper surface of the auxiliary barrel 3, a feed inlet on the discharge hopper 4, and a long pin 5 rotatably mounted inside the discharge hopper 4; an inner connecting plate 6 fixedly connected to the inner wall of the discharge hopper 4, a connecting shaft 7 rotatably mounted inside the inner connecting plate 6, and a reversing component between the long pin 5 and the connecting shaft 7.

[0023] The reversing component includes a fixed rod 11 fixedly connected to the end of the long pin 5, and a guide groove 12 is provided on the surface of the fixed rod 11. The guide groove 12 is annular and wavy. The long pin 5 is connected to the working rod through a pulley. A limit rod 15 is fixedly connected to the inner wall of the hopper 4. The end of the limit rod 15 is protruding. A movable plate 13 is slidably provided on the surface of the limit rod 15. A guide rod 14 is fixedly connected to the inner wall of the movable plate 13. The end of the guide rod 14 is bent and located inside the guide groove 12.

[0024] A rack 16 is fixedly connected to the outer wall of the movable plate 13, and a gear 19 that meshes with the rack 16 is fixedly connected to the surface of the connecting shaft 7. A limit groove 29 is opened inside the connecting shaft 7, and limit blocks 28 corresponding to the limit groove 29 are fixedly connected to both the left and right sides of the inner rod 9.

[0025] During operation, raw materials are fed into the feed hopper 4 through the feed inlet. Then, the motor 2 is started, which drives the working rod and the auger to complete the spiral conveying. When the motor 2 is working, the long pin 5 is driven to rotate inside the feed hopper 4 through the pulley. When the long pin 5 rotates, it drives the fixed rod 11 to rotate synchronously. At this time, the guide rod 14 and the movable plate 13 make reciprocating linear motion in the horizontal direction under the action of the guide groove 12 and the limit rod 15. At this time, the movable plate 13 drives the connecting shaft 7 to reciprocate inside the inner plate 6 through the rack 16 and the gear 19. The connecting shaft 7 drives the inner rod 9 to rotate synchronously through the limit block 28 and the limit groove 29. At this time, the striking rod 10 rotates synchronously, and the striking rod 10 plays the role of breaking up materials and preventing them from clumping.

[0026] Example 2: Unlike Example 1, the addition of a lifting component increases the working dimensions of the inner rod 9 and the striking rod 10, improving the dispersing effect. Figures 9-11 As shown, the inner shaft 7 is connected to the inner rod 9 through a lifting component, and the surface of the inner rod 9 is fixedly connected to a striking rod 10. The lower surface of the inner rod 9 is fixedly connected to a working plate 8. The lifting component includes a connecting spring 30 fixedly connected to the inner wall of the connecting shaft 7, and the other side of the connecting spring 30 is fixedly connected to the end of the inner rod 9. The upper surface of the long plate 23 is fixedly connected to a force-bearing block 24, and the striking rods 10 are evenly distributed on the surface of the inner rod 9.

[0027] The lower surface of the inner plate 6 is fixedly connected to a push block 22, and the end of the push block 22 and the end of the force block 24 are both arc-shaped structures. The push blocks 22 are distributed at equal angles on the lower surface of the inner plate 6. The auxiliary barrel 3 is a hollow frustum shape, the working plate 8 is a frustum shape, and the surface of the working plate 8 is provided with pressing blocks 20 at equal intervals. The working plate 8 is located inside the auxiliary barrel 3.

[0028] When the inner rod 9 is working, it rotates synchronously with the connecting shaft 7. At the same time, the inner rod 9 will drive the long plate 23 to rotate synchronously. When the long plate 23 rotates, the pushing block 22 will intermittently push the force block 24. When the force block 24 is pushed, the force block 24 will drive the inner rod 9 to descend inside the connecting shaft 7. At this time, the connecting spring 30 is stretched. When the force block 24 is not pushed, the inner rod 9 rises under the action of the connecting spring 30. That is, the inner rod 9 and the striking rod 10 make reciprocating linear motion in the vertical direction. At this time, the striking rod 10 can more efficiently disperse the material.

[0029] The inner rod 9 is fixedly connected to the working plate 8. When the inner rod 9 moves, it drives the working plate 8 and the extrusion block 20 to move synchronously. At this time, the extrusion block 20 is also in a multi-dimensional working state. The extrusion block 20 will efficiently break up the raw materials. At this time, the working plate 8 and the extrusion block 20 play a secondary role in preventing agglomeration.

[0030] Example 3: Unlike Example 2, the reciprocating component allows the wiping plate 25 to slide on the surface of the long plate 23, thereby efficiently wiping the inner wall of the hopper 4 without leaving material residue. Figure 10 and Figure 11 As shown; a long plate 23 is fixedly connected to the surface of the inner rod 9, and a wiping plate 25 is movably connected to the long plate 23 through a reciprocating component; the upper surface of the long plate 23 is convex, and the reciprocating component includes a return spring 27 fixedly connected to the convex position on the upper surface of the long plate 23, and the other side of the return spring 27 is fixedly connected to the inner wall of the wiping plate 25, and magnets 26 are provided on both the outer wall of the wiping plate 25 and the inner wall of the hopper 4. The magnets 26 are evenly distributed on the inner wall of the hopper 4, and the end magnetic poles of the magnets 26 on the surface of the wiping plate 25 are the same as the end magnetic poles of the magnets 26 on the inner wall of the hopper 4.

[0031] The surface of the wiping plate 25 is equipped with brushes. When the connecting shaft 7, the inner rod 9, and the long plate 23 rotate, the magnets 26 on the surface of the wiping plate 25 will intermittently approach the magnets 26 on the inner wall of the hopper 4. When the magnets 26 approach, the wiping plate 25 moves towards the direction of the compression return spring 27 under the action of mutual repulsive magnetic force. When the magnets 26 move away from each other, the wiping plate 25 returns to its original position under the action of the return spring 27. Repeating the above process, the wiping plate 25 will also make reciprocating linear motion on the surface of the long plate 23. Thus, when the wiping plate 25 works in multiple dimensions, it plays an efficient role in preventing residue.

[0032] Example 4: Unlike Example 2, the airbag 17 serves to remove heat and assist in dissipating it, such as... Figure 5 and Figure 9 As shown; An airbag 17 is bonded to the inner wall of the hopper 4; the surface of the airbag 17 is in contact with the surface of the movable plate 13, and an air inlet pipe is fixedly connected to the upper surface of the airbag 17. The lower surface of the airbag 17 is connected to the inner rod 9 through an air delivery hose 18. One-way valves are provided on the surface of the air delivery hose 18 and the surface of the air inlet pipe. Nozzles 21 are opened at equal angles on the surface of the working plate 8.

[0033] When the movable plate 13 reciprocates in a straight line in the horizontal direction, it will intermittently compress the airbag 17. When the airbag 17 is compressed, the airbag 17 supplies air to the inner rod 9, the working plate 8, and the nozzle 21 through the air supply hose 18. When the airbag 17 is not compressed, the airbag 17 inhales and expands through the air inlet pipe. That is, the airbag 17 will intermittently supply air to the working plate 8 and the nozzle 21 through the inner rod 9. At this time, the nozzle 21 intermittently sprays air, which can accurately impact the compressed particle clusters and enhance the anti-caking effect; at the same time, it blows the inner wall of the auxiliary barrel 3 to remove the adhering particles and remove frictional heat.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
