Description

Technical Field

[0001] The present invention belongs to the technical field of plastic recycling equipment, and in particular relates to a plastic waste recycling and processing device and a method thereof. Background Art

[0002] Plastic is a high-molecular compound formed by polymerization of monomers through addition or condensation reactions. Microplastics can harm human health. Its deformation resistance is medium, between that of fiber and rubber. It is composed of synthetic resin and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. Plastic products are made of plastic, a high-molecular compound formed by addition or condensation reactions, commonly known as plastics or resins, which can freely change their composition and shape. The production of plastic products will produce more waste leather pads, and the waste of plastic products can be crushed for recycling.

[0003] In the prior art, in order to improve the reuse effect of reusable resources, the existing plastic recycling and reuse process first needs to recycle the plastic waste, and then facilitate the subsequent processing of the plastic waste in different directions according to actual processing needs. In the actual collection process of plastic waste recycling, only the movement and transfer of the plastic waste storage position is achieved. At the same time, due to the irregular structure of the plastic waste in the actual collection process, the plastic waste is prone to cause excessive space waste in the stacking process, resulting in the need to transfer and place the plastic waste multiple times, which prolongs the time of plastic waste recycling and reduces the actual recycling efficiency. At the same time, it is not convenient for the subsequent processing of plastic waste, resulting in poor actual use effect of the existing plastic waste recycling equipment. Summary of the invention

[0016] A method for recycling plastic waste comprises the following steps:

[0017] S1. Connecting with the existing transport device: Connecting the mobile frame with the existing transport device through the connecting seat, so that the existing transport device can pull the mobile frame to move under the support of the moving wheels, and the moving wheels will rotate in the process of supporting the movement of the mobile frame, so that the two moving wheels respectively drive the linkage shaft and the conveying shaft to rotate;

[0018] S2, preliminary treatment: inject a proper amount of water into the storage space formed between the side frame, the extension frame and the adjustment frame, so that the water level submerges the lowest point of the inner wall of the installation circle. At this time, the relatively clean plastic waste is injected into the side frame through the injection frame, and the plastic waste with more foreign matter is injected into the rotating frame through the guide pipe. Then, driven by the conveying shaft, the filter rod can clean and separate the plastic waste and foreign matter. Finally, the floating plastic waste is gradually pushed into the cutting circle by the pushing action of the conveying shaft.

[0019] S3, recycling and cutting process: the rotating linkage shaft drives the elastic linkage tube to rotate, and at the same time, under the extrusion of the counterweight component, part of the inner wall of the cutting ring can be closely attached to the inner wall of the first limiting groove, so that the rotating elastic linkage tube can drive the cutting ring to rotate along the inner wall direction of the second limiting groove, so that a shearing effect is formed at the joint of the outer wall of the cutting ring and the inner wall of the second limiting groove, and at the same time, a shearing effect is formed at the joint of the inner wall of the third limiting groove and the inner wall of the cutting ring, and there is also a shearing effect between the outer surface of the counterweight tube and the outer surface of the cutting strip, and between the outer surface of the cutting strip and the inner wall of the side frame;

[0020] S31, external transverse and longitudinal cutting processing: when the plastic waste is injected into the side frame through the injection frame or pushed into the inside of the side frame through the conveying shaft, when the plastic waste falls between the outer surface of the cutting ring and the inner wall of the side frame, the rotating cutting ring will perform longitudinal cutting processing on the plastic waste, and the plastic waste will be transversely cut by squeezing the outer surface of the cutting strip and the inner wall of the side frame;

[0021] S32. Internal cutting and processing: When the plastic waste is pushed into the cutting circle through the conveying shaft, the outer wall of the counterweight tube cooperates with the inner wall of the cutting circle and the outer wall of the cutting strip, thereby realizing efficient cutting and processing of the plastic waste. The irregular plastic waste is gradually squeezed and then cut into smaller and more regular fragments. The rotating adjustment frame changes its angle, and finally the smaller and more regular fragments are transferred to the interior of the existing transportation device.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] (1) In the present invention, when in use, the mobile frame is connected to the existing transport device through the connecting seat, so that the existing transport device can pull the mobile frame to move its position under the support of the mobile wheels. At the same time, the mobile wheels will rotate during the movement of the supporting mobile frame, thereby causing the two mobile wheels to respectively drive the linkage shaft and the conveying shaft to rotate, and at the same time, inject a proper amount of water resources into the storage space formed between the side frame, the extension frame and the adjustment frame, so that the water resource liquid level submerges the lowest point of the inner wall of the installation circle. At this time, the relatively clean plastic waste is injected into the side frame through the injection frame, and the plastic waste with more adhered foreign matter is injected into the rotating frame through the guide pipe. Then, under the drive of the conveying shaft, the filter rod can clean and separate the plastic waste and foreign matter. Through the pushing action of the conveying shaft, the floating plastic waste is finally gradually pushed into the cutting circle, and then the plastic waste can be efficiently pre-processed before being collected and sent to the processing site, which is convenient for subsequent processing after arriving at the processing site, thereby improving the overall recycling efficiency of the plastic waste.

[0024] (2) In the present invention, when in use, the rotating linkage shaft drives the elastic linkage tube to rotate, and at the same time, under the extrusion of the counterweight component, part of the inner wall of the cutting ring can be closely fitted to the inner wall of the first limiting groove, so that the rotating elastic linkage tube can drive the cutting ring to rotate along the inner wall direction of the second limiting groove, so that a shearing effect is formed at the joint of the outer wall of the cutting ring and the inner wall of the second limiting groove, and at the same time, a shearing effect is formed at the joint of the inner wall of the third limiting groove and the inner wall of the cutting ring, and there is also a shearing effect between the outer surface of the counterweight tube and the outer surface of the cutting strip, and between the outer surface of the cutting strip and the inner wall of the side frame. When the plastic waste is injected into the side frame through the injection frame or pushed into the inside of the side frame through the conveying shaft, when the plastic waste falls between the outer surface of the cutting ring and the inner wall of the side frame, the rotating cutting ring will longitudinally cut the plastic waste. During the cutting process, the outer surface of the cutting strip and the inner wall of the side frame are squeezed to perform transverse cutting of the plastic waste. When the plastic waste is pushed into the cutting circle through the conveying shaft, the outer wall of the counterweight tube cooperates with the inner wall of the cutting circle and the outer wall of the cutting strip to perform efficient cutting of the plastic waste, thereby gradually squeezing and cutting the irregular plastic waste into smaller and more regular pieces. At this time, the more regular plastic waste fragments can be transferred to the existing transportation device by rotating the adjustment frame using an angle, thereby effectively completing the recycling of the plastic waste and facilitating the subsequent directional processing of the plastic waste, and enabling the existing transportation device to collect and transfer more plastic waste, effectively reducing the number of centralized collection times and improving the actual recycling efficiency.

Connecting to an existing transport device: connecting the mobile frame (101) to the existing transport device via a connecting seat (102), so that the existing transport device can pull the mobile frame (101) to move under the support of the moving wheels (103), and the moving wheels (103) will rotate in the process of supporting the movement of the mobile frame (101), thereby causing the two moving wheels (103) to respectively drive the linkage shaft (104) and the conveying shaft (106) to rotate; S2, preliminary treatment: injecting an appropriate amount of water into the storage space formed between the side frame (108), the extension frame (301) and the adjustment frame (302) so that the water level submerges the lowest point of the inner wall of the installation circle (111); at this time, relatively clean plastic waste is injected into the side frame (108) through the injection frame (109); plastic waste with a large amount of adhered foreign matter is injected into the interior of the rotating frame (110) through the guide pipe (303); and then, driven by the conveying shaft (106), the filter rod (112) is able to clean and separate the plastic waste and foreign matter; and finally, the floating plastic waste is gradually pushed into the interior of the cutting circle (202) through the pushing action of the conveying shaft (106); S3, recycling and cutting process: the rotating linkage shaft (104) drives the elastic linkage tube (105) to rotate, and at the same time, under the pressure of the counterweight component, part of the inner wall of the cutting ring (202) can be closely attached to the inner wall of the first limiting groove, so that the rotating elastic linkage tube (105) can drive the cutting ring (202) to rotate along the inner wall of the second limiting groove, so that a shearing effect is formed at the joint between the outer wall of the cutting ring (202) and the inner wall of the second limiting groove, and at the same time, a shearing effect is formed at the joint between the inner wall of the third limiting groove and the inner wall of the cutting ring (202), and a shearing effect is also formed between the outer surface of the counterweight tube (203) and the outer surface of the cutting strip (201), and between the outer surface of the cutting strip (201) and the inner wall of the side frame (108); S31, external transverse and longitudinal cutting processing: when the plastic waste is injected into the side frame (108) through the injection frame (109) or pushed into the inside of the side frame (108) through the conveying shaft (106), when the plastic waste falls between the outer surface of the cutting ring (202) and the inner surface wall of the side frame (108), the rotating cutting ring (202) will perform longitudinal cutting processing on the plastic waste, and the plastic waste will be cut transversely by squeezing the outer surface of the cutting strip (201) and the inner wall of the side frame (108); S32, internal cutting processing: When the plastic waste is pushed into the cutting ring (202) through the conveying shaft (106), the outer wall of the counterweight tube (203) cooperates with the inner wall of the cutting ring (202) and the outer wall of the cutting strip (201), thereby realizing efficient cutting processing of the plastic waste. The irregular plastic waste is gradually squeezed and then cut into smaller and more regular fragments. The rotating adjustment frame (302) changes its angle, and finally the smaller and more regular fragments are transferred to the interior of the existing transportation device.
