Technical Field
[0001] This invention belongs to the field of plastic film recycling technology, and more specifically, relates to a plastic film waste recycling and compression device. Background Technology
[0002] Plastic film production and use generate a large amount of scrap and waste materials. These waste materials are thin and fluffy, and direct stacking not only occupies a lot of storage space but also hinders subsequent transportation and recycling. Therefore, the industry commonly uses compression devices to compact plastic film waste. Currently, the compression equipment used for plastic film waste recycling mainly relies on the pressure head to extrude and shape the waste material in the cavity. It is widely used in plastic product manufacturing enterprises, recycling sites, and other scenarios, and is an indispensable supporting equipment in the resource recycling process of plastic waste.
[0003] However, when unloading, the molded material blocks in current compression equipment tend to stick to the cavity wall and get stuck. Usually, workers need to manually pry them to complete the discharge, which increases labor intensity and poses safety risks. At the same time, the equipment relies on the lifting and lowering of the pressing component to open and close the compression cavity. During operation, it has been found that when some plastic film material is exposed, workers often clean up the exposed material by hand. When the pressing component is running, it can easily cause crushing accidents, making it difficult to guarantee the safety of the operation.
[0004] In view of this, the present invention is proposed. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.
[0020] like Figures 1 to 9As shown, a plastic film waste recycling and compression device includes a base 1, with support rods 2 connected to the four corners of the base 1, and two uprights 3 connected to the middle of the base 1. A top plate 4 is fixed to the top of the support rods 2 and the uprights 3. A pressing assembly 5 is slidably mounted on the top plate 4. A driven plate 6 is rotatably mounted between adjacent support rods 2 and uprights 3, and an active plate 7 is rotatably mounted between adjacent support rods 2. A partition 8 is connected between the two uprights 3. The active plate 7, driven plate 6, and partition 8 enclose and separate to form a first compression chamber 29 and a second compression chamber 30 arranged on the left and right. A gear assembly for synchronous rotation is assembled between the active plate 7 and driven plate 6. A discharge assembly is mounted on the base 1 below the first compression chamber 29 and the second compression chamber 30. A transmission mechanism is connected between the discharge assembly and the active plate 7. A pressure sensing component is arranged on the pressing assembly 5, and an electric push rod 26 for driving the pressing assembly 5 to move is mounted on the top plate 4. In this setup, a support frame is formed by the base 1, support rod 2, and upright rod 3. A dual compression station is formed by the partition plate 8, active plate 7, and driven plate 6. The electric push rod 26 drives the pressing component 5 to switch stations. The opening and closing of the plate is controlled by the gear assembly and transmission mechanism, and the unloading component is used to achieve unloading. Pressure sensing components ensure the safety of equipment compression and operation, realizing an integrated waste recycling compression operation with alternating compression at dual stations and automatic unloading.
[0021] like Figures 1 to 9 As shown, in a specific embodiment, the pressing assembly 5 includes a mounting plate 51, a first hydraulic cylinder 52, and a compression plate 53. A movable groove 41 is provided inside the top plate 4. Movable blocks 56 are connected to both sides of the mounting plate 51, and the movable blocks 56 are slidably embedded inside the movable groove 41. A connecting plate 27 is connected to the output end of the electric push rod 26, and the connecting plate 27 is connected to the mounting plate 51. In this configuration, the electric push rod 26 drives the mounting plate 51 through the connecting plate 27, causing the mounting plate 51 to slide laterally along the movable groove 41 of the top plate 4 with the help of the movable blocks 56 on both sides. This drives the entire pressing assembly 5 to switch positions, correspondingly aligning with the first compression chamber 29 or the second compression chamber 30, realizing alternating compression operations at two positions. The sliding cooperation between the movable groove 41 and the movable blocks 56 can limit the movement trajectory of the pressing assembly 5.
[0022] like Figures 1 to 9As shown, a first hydraulic cylinder 52 is vertically mounted in the middle of the mounting plate 51. The output end of the first hydraulic cylinder 52 is connected to a compression plate 53. A guide sleeve 54 is fixed on the mounting plate 51, and a guide rod 55 is vertically slidably mounted inside the guide sleeve 54. The lower end of the guide rod 55 is fixedly connected to the top surface of the compression plate 53. In this configuration, the first hydraulic cylinder 52 drives the compression plate 53 to move up and down, completing the compression operation of the plastic film waste inside the compression chamber. At the same time, through the vertical sliding cooperation between the guide sleeve 54 and the guide rod 55, the downward pressing and resetting actions of the compression plate 53 are guided, ensuring a smooth compression process and improving the regularity of the compressed waste.
[0023] like Figures 1 to 9 As shown, furthermore, a first pressure sensor 57 is embedded in the bottom surface of the compression plate 53, and an upper through-strip groove 59 is formed on the plate body of the compression plate 53. Second pressure sensors 58 are embedded in the left and right end faces of the mounting plate 51. In this configuration, when the compression plate 53 presses down to compress waste material, the first pressure sensor 57 on the bottom surface can detect the compression pressure, and the compression start / stop and pressure holding processes are controlled according to the pressure value to avoid insufficient pressure causing the material to loosen or excessive pressure damaging the equipment. Simultaneously, the second pressure sensors 58 on both sides of the mounting plate 51 can sense obstacles or human contact during the lateral movement of the pressing assembly 5, stopping the movement and providing a through-strip channel for binding the material in conjunction with the upper through-strip groove 59.
[0024] like Figures 1 to 9 As shown, the gear assembly further includes a driving helical gear 13 and a driven helical gear 12. A rotating shaft 11 is mounted in the driving plate 7, and a rotating shaft 10 is mounted in the driven plate 6. The rotating shafts 11 and 10 are rotatably mounted on the support rod 2 and the upright rod 3. Driving helical gears 13 are mounted at both ends of the rotating shaft 11, and driven helical gears 12 are mounted at the end of the rotating shaft 10. The driving helical gears 13 and the corresponding driven helical gears 12 mesh and transmit power. In this configuration, the driving plate 7 rotates within the support rod 2 via the rotating shaft 11. During rotation, the driving helical gears 13 at the shaft end rotate synchronously, driving the driven helical gears 12 and the corresponding rotating shafts 10 to rotate through gear meshing transmission. This, in turn, drives the driven plates 6 on both sides to open and close synchronously, achieving synchronized action between the driving plate 7 and the driven plates 6, ensuring that the entire cavity opens or closes synchronously.
[0025] like Figures 1 to 9 As shown, the gear assembly is further installed inside the support rod 2, and a cover plate 9 is installed at the top of the support rod 2. In this configuration, the gear assembly is completely housed inside the support rod 2, protecting the driving helical gear 13 and driven helical gear 12 in the meshing transmission. This prevents dust and waste debris from entering the gear meshing gap during operation, causing jamming and wear. At the same time, the top cover plate 9 provides sealed protection, facilitating the disassembly and maintenance of the gear assembly in the future, and ensuring the long-term stable operation of the transmission structure.
[0026] like Figures 1 to 9 As shown, the unloading assembly further includes a second hydraulic cylinder 20, an unloading plate 21, a telescopic sleeve 22, and a telescopic rod 23. The second hydraulic cylinder 20 is vertically mounted on the base 1, and the output end of the second hydraulic cylinder 20 is connected to the unloading plate 21. The telescopic sleeve 22 is also vertically fixed on the base 1, and the telescopic rod 23 is vertically slidably mounted inside the telescopic sleeve 22. The top end of the telescopic rod 23 is connected to the bottom surface of the unloading plate 21. The unloading plate 21 has a groove 28 for lowering the strip. In this configuration, the second hydraulic cylinder 20 drives the unloading plate 21 to move up and down, completing the unloading and support of the formed material block. At the same time, the sliding cooperation between the telescopic sleeve 22 and the telescopic rod 23 can guide and support the lifting action of the unloading plate 21, preventing the unloading plate 21 from tilting or shifting under force, and improving the lifting stability. The groove 28 for lowering the strip on the unloading plate 21 can cooperate with the upper stripping structure to form a path for binding and threading the material block.
[0027] like Figures 1 to 9 As shown, the transmission mechanism further includes a sliding rod 15, a sliding seat 16, a slider 19, and a cam 18. Two parallel sliding grooves 17 are provided on the active plate 7. The sliding seat 16 is slidably installed inside the sliding grooves 17, and the sliding rod 15 is connected to the sliding seat 16. In this configuration, during the lifting and lowering process of the unloading plate 21, the sliding rod 15 can be driven to move synchronously, causing the sliding seat 16 at the top of the sliding rod 15 to slide adaptively along the sliding grooves 17 of the active plate 7. The sliding cooperation between the sliding grooves 17 and the sliding seat 16 matches the displacement trajectory of the sliding rod 15, preventing transmission jamming and realizing the transmission of the lifting action of the unloading plate 21 to the rotation action of the active plate 7, providing transmission power for the opening and closing of the plate.
[0028] like Figures 1 to 9 As shown, the unloading plate 21 has two straight grooves 25, and the side wall of the support rod 2 has an inclined cam groove 24. The lower ends of the sliding rod 15 are connected to the cam 18 and the slider 19. The slider 19 is slidably embedded in the straight groove 25, and the cam 18 is slidably engaged in the cam groove 24. In this configuration, when the unloading plate 21 descends, it can drive the slider 19 to move through the straight groove 25. At the same time, the cam 18 at the lower end of the sliding rod 15 slides along the trajectory of the inclined cam groove 24 of the support rod 2, causing the sliding rod 15 to deflect. This displacement is then caused by the sliding block 16 to pull the active plate 7 to rotate, converting the vertical linear motion of the unloading plate 21 into the rotational motion of the active plate 7, thus realizing the mechanical linkage between the unloading action and the opening and closing action of the plate.
[0029] like Figures 1 to 9As shown, the driven plate 6 further includes a side-through groove 14, which, along with the upper through groove 59 and the lower through groove 28, forms a path for the strapping. In this configuration, the corresponding cooperation of the side-through groove 14 on the driven plate 6, the upper through groove 59 on the compression plate 53, and the lower through groove 28 on the unloading plate 21 allows for a wraparound strapping operation on the compressed plastic film block.
[0030] The implementation principle of the plastic film waste recycling and compression device in this embodiment is as follows: In use, the electric push rod 26 is first activated. The electric push rod 26, through the connecting plate 27, drives the pressing component 5 to move horizontally along the moving groove 41 inside the top plate 4 using the moving blocks 56 on both sides of the mounting plate 51. This moves the pressing component 5 above the second compression chamber 30, at which point the top of the first compression chamber 29 is completely open, allowing the operator to deposit the plastic film waste to be processed into the first compression chamber 29. After the first compression chamber 29 is filled, the electric push rod 26 is controlled to reverse its movement, pushing the pressing component 5 to slide directly above the first compression chamber 29. The top of the second compression chamber 30 then opens, allowing the second compression chamber 30 to be replenished with plastic film waste, achieving alternating feeding operations at two stations. During the movement of the pressing component 5, if it accidentally touches a person or foreign object on its side, the second pressure sensors 58 on both sides of the mounting plate 51 will trigger a signal, controlling the electric push rod 26 to stop, preventing pinching accidents.
[0031] After the pressing component 5 is positioned above the first compression chamber 29, the first hydraulic cylinder 52 is activated. The output end of the first hydraulic cylinder 52 pushes the compression plate 53 to move vertically downward. The guide sleeve 54 on the mounting plate 51 and the guide rod 55 cooperate to limit and guide the movement trajectory of the compression plate 53, ensuring that the downward pressure does not deviate. The compression plate 53 gradually squeezes the plastic film waste inside the first compression chamber 29. The first pressure sensor 57 on the bottom surface of the compression plate 53 detects the pressure value generated during the compression process. When the pressure reaches the preset value, the control system immediately shuts down the first hydraulic cylinder 52, and the compression plate 53 stops descending and maintains the current state to complete a short-term pressure holding, thereby improving the compactness of the material block.
[0032] After the pressure holding process is completed, the operator passes the strapping tape through the upper strapping groove 59 on the compression plate 53, the side strapping groove 14 on the driven plate 6, and the lower strapping groove 28 on the unloading plate 21 to wrap around the compressed material block. After the binding operation is completed, the first hydraulic cylinder 52 is controlled to retract, driving the compression plate 53 to return to its original position and detach it from the internal space of the first compression chamber 29. Then, the second hydraulic cylinder 20 on the base 1 is activated. The output end of the second hydraulic cylinder 20 pulls the unloading plate 21 downward as a whole. During the downward movement of the unloading plate 21, the telescopic sleeve 22 and the telescopic rod 23 on the base 1 cooperate with each other to support and guide the unloading plate 21, ensuring its vertical movement.
[0033] When the unloading plate 21 moves downward, the straight grooves 25 on both sides drive the internal slider 19 to move synchronously. The slider 19 then pulls the sliding rod 15 to move. The cam 18 at the lower end of the sliding rod 15 slides along the cam groove 24 inclined on the side wall of the support rod 2, causing the sliding rod 15 to deflect accordingly. At the same time, the slide block 16 connected to the top of the sliding rod 15 slides along the slide groove 17 on the active plate 7, thereby driving the active plate 7 to rotate outward around the rotation axis 11. During the rotation of the active plate 7, the active helical gears 13 at both ends of its rotation axis 11 operate synchronously, driving the driven helical gear 12 and the corresponding rotation axis 10 to rotate through the gear meshing relationship, ultimately driving the driven plate 6 to open outward synchronously with the active plate 7, releasing the wrapping and limiting of the material block. At this time, the compressed and bound plastic film block loses its enclosure constraint and falls together with the unloading plate 21, completing the unloading. During the compression, bundling, and unloading process in the first compression chamber 29, the second compression chamber 30 can continuously perform feeding operations. The two compression chambers alternately cycle to continuously complete the recycling and compression processing of plastic film waste.
[0034] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
