[0016] 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.

[0017] Please see Figure 1-6 The present invention provides a technical solution: a release film waste recycling device, including a recycling bin 1. The recycling bin 1 is mainly composed of a bin body 2 and a support plate 3. The support plate 3 is fixedly installed in the upper middle area inside the bin body 2 to support the stirring component. The stirring component is set in the middle area of ​​the support plate 3. The stirring component is used to efficiently crush the release film in the bin body 2 to ensure that the fragments are uniform and fine. Release film waste enters the interior of chamber 2 through the top inlet and falls into the space below the support plate 3. After the stirring component is started, the waste is continuously crushed. After crushing, the fragments enter the subsequent recycling stage through the discharge outlet at the bottom of the chamber. The upper and middle areas of the support plate 3 provide ample space for the agitation components to crush materials, while preventing waste from directly impacting the support plate and causing damage. The uniform and fine fragments after efficient crushing can significantly improve the melting efficiency of subsequent recycling and reprocessing, and reduce energy consumption and impurity residues during the melting process. The stirring assembly includes a motor structure 4 fixedly mounted on the top of the support plate 3. The motor structure 4 adopts a shockproof design to ensure stable operation. Its output end faces downward and the stirrer 5 is fixedly mounted on it. After the motor structure 4 is powered on, the output shaft drives the agitator 5 to rotate at a set speed; the anti-vibration design controls the vibration amplitude of the motor during operation within a preset time, avoiding the vibration from being transmitted to the chamber body 2 and the support plate 3. The stirrer 5 includes a first stirring rod 6 fixedly installed at the output end of the motor structure 4. The first stirring rod 6 is a rigid structure, and a first motor 7 is fixedly installed at its end. The output end of the first motor 7 faces downward and a second stirring rod 8 is fixedly installed. Several second motors 9 are arranged sequentially from top to bottom on the side wall of the second stirring rod 8. A stirring plate 10 is fixedly installed at the output end of the second motor 9. The stirring plate 10 is made of wear-resistant material and crushes the release film at multiple angles through rotational motion. The motor structure 4 drives the first stirring rod 6 to rotate 360 ​​degrees, while the first motor 7 drives the second stirring rod 8 to rotate in the opposite direction. The second motor 9 drives the stirring plate 10 to rotate at multiple angles. Under the coordinated action of the three, the stirring plate 10 impacts, shears and grinds the release film in the chamber, achieving all-round crushing. In the mixing assembly, the first mixing rod 6 drives the second mixing rod 8 to rotate in the opposite direction. The mixing plate 10 on the second mixing rod 8 is driven by the second motor 9 to rotate at high speed at multiple angles. In this motion mode, the mixing plate 10 forms a high-frequency impact on the release film waste entering the chamber, directly breaking large, flexible release film into small fragments, preventing large pieces of film from getting tangled on the mixing rod due to their flexibility. The impact force generated by the impact can break up the initially gathered film sheets, preventing them from forming a tangled base around the mixing rod. The distribution of the stirring plates from top to bottom covers the side wall of the second stirring rod, and the impact range without dead angles ensures that the membrane in all areas is treated in a timely manner; The rotation direction of the stirring plate and the rotation direction of the stirring rod form a cross shearing force. When a small amount of debris begins to wrap around the stirring rod, the edge of the stirring plate will contact the wrapping point in a shearing posture, cutting or peeling off the wrapped debris. The second motor 9 drives the stirring plate to rotate independently at multiple angles. This dynamically adjusted shearing angle can cope with entanglement in different directions, further improving the peeling effect. The mixing plate is made of wear-resistant rigid material, which will not deform due to shear force, ensuring long-term stable peeling ability. The bottom of the chamber 2 is equipped with a drain pipe 11 for discharging the crushed release film fragments. A support frame 12 is fixedly installed at the bottom of the container 2. The support frame 12 is a steel structure that provides stable support. A fan 13 is installed inside the support frame 12. The air outlet of the fan 13 is connected to the first duct 14. The first duct 14 is connected to the lower drain pipe 11, and the end of the first duct 14 is connected to an external recovery structure. The fan 13 helps the debris enter the lower drain pipe 11 through negative pressure suction. The bottom middle area of ​​the chamber 2 is provided with a first lower discharge port 15, which is connected to the lower recovery component through a hose to ensure smooth transport of debris. A second discharge port 16 is provided at the bottom of the lower discharge pipe 11. The second discharge port 16 is connected to the lower recovery assembly through a hose and serves as an auxiliary discharge port. The lower recycling assembly includes a first support housing 17, and a first recycling box 18 is provided at the beginning region of the first support housing 17. The first recycling box 18 receives release film fragments discharged from the first lower discharge port 15 and the second lower discharge port 16 and performs preliminary collection. The crushed release membrane fragments fall to the bottom of the chamber 2 under the action of gravity and are discharged along the lower discharge pipe 11. If the release membrane fragments have been shredded to a preset degree, they are highly fragmented and lightweight, and are then recycled by the external recycling structure. The external recycling structure uses wind power to recycle and can only recycle release membrane fragments of a preset weight. Larger release membrane fragments enter the lower recycling component through the first lower discharge port 15 and undergo the crushing process again until they are recycled by the external recycling structure. The dual bottom discharge design increases the maximum processing capacity of the release film. Compared with repeated mixing and crushing, this method can obtain release film fragments of a preset quality, while also preventing equipment blockage caused by excessive flow. The presence of dual bottom discharge ports enhances the fault tolerance of the device, and even if a single outlet fails, it can still maintain some discharge function. The first support housing 17 is provided with an inclined first conveying assembly 38, which is a belt conveyor used to convey the fragments upward. The first recycling box 18 receives the fragments from the second lower discharge port 16 and sends the fragments into the first conveying assembly 38. The first recycling box 18 acts as a buffer to prevent debris from directly impacting the conveying components, reducing component wear; the preliminary collection function makes the debris flow more stable, improving the efficiency of subsequent conveying stages; the integrated design of the first support shell 17 enhances the structural strength of the lower recycling components. A first drive member 19 is provided on one side of the first conveying assembly 38. The first drive member 19 provides power. A first auxiliary assembly connected to the first drive member 19 is provided at the bottom end region of the first conveying assembly 38. The first auxiliary assembly includes a first roller 20 connected to the output end of the first drive member 19. Several first scrapers 21 are installed on the side wall of the first roller 20. The first scrapers 21 are used to sweep the release film fragments on the surface of the first conveying assembly 38 into the lifting chamber 22 provided on one side of the first conveying assembly 38 to ensure that the fragments are completely transferred. The conveyor belt of the first conveying assembly 38 operates at a set speed, conveying the fragments discharged from the first recycling box 18 downwards at an angle until they reach the bottom end area. The first driving member 19 simultaneously drives the first conveying assembly 38 and the first roller 20 to operate. The first roller 20 drives the first scraper 21 to rotate, sweeping the release film fragments on the surface of the conveyor belt into the slot 23 of the lifting chamber 22, so that the release film fragments enter the lifting chamber 22. The sweeping function of the first scraper 21 reduces the residual rate of the conveyor belt and improves the recycling rate. The unified drive component reduces the number of power sources, reduces energy consumption and maintenance costs. The synchronous operation of the first roller 20 ensures that the sweeping timing matches the conveying rhythm and avoids the scattering of fragments.

[0018] A slot 39 is provided at the connection between the lifting chamber 22 and the first conveying component 38 to facilitate the entry of fragments; The debris swept down by the first scraper 21 falls directly into the lower chamber 23 of the lifting chamber 22 through the slot 23. The size of the slot is adapted to the width of the scraper to ensure that all the debris enters. The precise positioning of the slot 23 prevents the debris from scattering outside the device, reduces material waste, and ensures smooth conveying. The lifting chamber 22 includes a lower chamber 23 and an upper chamber 24. A second conduit 25 is provided between the lower chamber 23 and the upper chamber 24. An intelligent valve 26 is installed inside the second conduit 25 to control the flow of fragments. A second drive unit 27 is provided on one side of the lower chamber 23. A pump 28 is provided at the bottom area of ​​the second conduit 25. The pump 28 is used to transport the release film fragments in the lower chamber 23 into the upper chamber 24 to achieve vertical lifting. A discharge pipe 29 facing the upward recycling component is provided on one side of the upper chamber 24. The discharge pipe 29 is connected to a third drive unit 30 provided on one side of the upper chamber 24. The third drive unit 30 controls the opening and closing of the discharge pipe 29 to ensure that the fragments are discharged as needed. After the fragments enter the lower chamber 23, the second drive unit 27 starts to transport the release film fragments in the lower chamber 23 to the upper chamber 24. The intelligent valve 26 is in the normally open state, and the pump 28 starts to transport the fragments to the upper chamber 24 through the second conduit 25. After the mass of release film fragments in the upper chamber 24 reaches the set amount, the third drive unit 30 controls the discharge pipe 29 to open, and the fragments enter the upper recycling component through the discharge pipe 29 to ensure the successful delivery of the release film fragments. The upper recycling component is positioned above the lower recycling component. The upper recycling component includes a second support housing 31, with a second recycling box 32 at its starting end. The second recycling box 32 receives release film fragments from the discharge pipe 29 and conveys them into the hopper 2 for recycling. An inclined second conveying component 33, a belt conveyor, is mounted on the second support housing 31 to lift the fragments to the top of the hopper 2. The fragments discharged from the discharge pipe 29 enter the second recycling box 32, and then enter the second conveying component 33. The second recycling box 32 buffers the fragment flow rate to prevent the upper conveying component from jamming due to excessive instantaneous flow. The box body is made of transparent material, which makes it easy to observe the fragment quantity in real time and adjust the operating parameters in a timely manner. A fourth drive member 34 is provided on one side of the second conveying assembly 33. The fourth drive member 34 provides power. A second auxiliary assembly connected to the fourth drive member 34 is provided at the bottom end region of the second conveying assembly 33. The second auxiliary assembly includes a second roller 35 connected to the output end of the fourth drive member 34. Several second scrapers 36 are installed on the side wall of the second roller 35. The second scrapers 36 are used to sweep the release film fragments on the surface of the second conveying assembly 33 into the chamber 2 provided on one side of the second conveying assembly 33, ensuring that the fragments completely enter the chamber 2. The conveyor belt of the second conveying component 33 operates at a preset speed, conveying the fragments in the second recycling box 32 upwards at an angle to the top of the bin 2. A discharge pipe 37 is installed at the top of the bin 2, and the discharge pipe 37 is connected to the top of the second recycling box 32, so that the fragments can flow back into the bin 2 for further processing or final collection. The fourth driving component 34 simultaneously drives the second conveying assembly 33 and the second roller 35 to operate; the second roller 35 drives the second scraper 36 to rotate, sweeping the debris remaining on the surface of the conveyor belt into the discharge pipe 37 at the top of the bin 2. The fragments return to the inside of the bin 2 through the feed pipe 37. If the fragment size does not meet the standard, it will re-enter the mixing component for secondary crushing. If it meets the standard, it will be discharged to the external recycling structure through the discharge pipe 11, forming a complete closed-loop recycling system, improving the intelligence level of the device. The cyclic processing ensures that the fragment qualification rate is high and meets the requirements, satisfying the requirements of high-end recycling and reuse.
