Description

Technical Field

[0001] This invention relates to the field of film recycling technology, specifically to a novel friction cleaning device for recycling plastic films. Background Technology

[0002] With the continuous development of technology and the rapid progress of society, the plastic film industry is experiencing a period of vigorous development. Plastic film is most widely used in the packaging field, for food packaging, electrical appliance packaging, daily necessities packaging, clothing packaging, and more. Due to its non-degradability, discarding used, dirty plastic film causes significant environmental damage and resource waste. Therefore, recycling used plastic film, through crushing and cleaning, allows for its reuse. Plastic film recycling friction cleaning equipment is a key piece of equipment in the waste plastic film recycling production line, mainly used to remove impurities such as mud, organic particles, and oil stains from the surface of the plastic film. Cleaning is necessary during the recycling of plastic film; therefore, cleaning equipment is required.

[0003] Currently, in existing methods of recycling and cleaning plastic film, the plastic film fragments tend to accumulate and stick together, making it difficult to remove impurities adhering to the surface of the plastic film fragments and affecting the cleaning effect. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: A novel friction cleaning device for recycling plastic film includes: A cleaning tank, and a hydraulic rod fixedly installed on the side of the surface of the cleaning tank, a drain pipe is installed on the side of the bottom of the cleaning tank, and a top cover is fixedly connected to the telescopic end of the hydraulic rod; A debris cleaning mechanism includes a first rotating shaft, a driver, and a second rotating shaft. The first rotating shaft is rotatably mounted on the side of the inner cavity of the top cover. The driver is fixedly mounted on the end of the surface of the top cover. The second rotating shaft is rotatably mounted in the middle of the top of the inner cavity of the top cover. A partition plate is fixedly connected to the outer circumference of the first rotating shaft, and the partition plates are evenly distributed on the outer circumference of the first rotating shaft. The partition plates are evenly distributed along the axial direction of the first rotating shaft. A pull hook is fixedly connected to the outer edge of the partition plate. An elastic brush is fixedly connected to the annular surface of the partition plate, and the elastic brush is evenly distributed on the annular surface of the partition plate. The second rotating shaft... A beater plate is fixedly connected to the outer circular surface of the shaft. A spray assembly is installed between the top of the top cover and the bottom of the surface of the cleaning tank. By contracting the extension end of the hydraulic rod, a pulling force can be applied to the top cover, which can cause the top cover to move the entire debris cleaning mechanism downward. The top cover is used to cover the top of the cleaning tank, sealing the opening at the top of the cleaning tank. When cleaning plastic film fragments, water will not splash out. By extending the extension end of the hydraulic rod, an upward pushing force can be applied to the top cover, which can cause the top cover to move the debris cleaning mechanism upward. The top cover separates from the top of the cleaning tank and is opened. The height of the top cover can be adjusted to facilitate feeding and removing materials from the cleaning tank.

[0005] The top cover is placed on top of the cleaning tank, with the bottom of the top cover matching the top of the cleaning tank. The separators are evenly distributed on the outer surface of the first rotating shaft, which separates the plastic film fragments floating on the liquid surface, making it less likely for a large number of film fragments to accumulate, and facilitating the subsequent cleaning of the film fragments.

[0006] Preferably, one end of the first rotating shaft, one end of the second rotating shaft, and the output end of the driver are fixedly installed via a coupling. The striking plates are evenly distributed on the outer circumference of the second rotating shaft, and the striking plates are made of rubber. By rotating the output end of the driver, the first rotating shaft can be driven to rotate, causing the separator to rotate along with the first rotating shaft. The rotation of the separator can drive the pull hook to rotate circumferentially, hooking up the plastic film fragments floating on the liquid surface, thus separating the plastic film fragments that are stuck together. Furthermore, since the pull hook is made of rubber, it has good flexibility, and the pull hook makes flexible contact with the plastic film fragments, making it less likely to damage the plastic film fragments.

[0007] Preferably, the actuating hooks are evenly distributed on the outer edge of the separator plate. The actuating hooks are arc-shaped and made of rubber. The separator plate is rotated by the first rotating shaft, which causes the elastic brush to rotate as well. The elastic brush brushes the surface of the plastic film fragments and, under the influence of friction, washes away the debris attached to the surface of the plastic film fragments, thereby achieving friction cleaning.

[0008] The second shaft is driven to rotate by the output of the driver, causing the beater to rotate along with the second shaft. The beater will beat on the plastic film fragments, which not only causes the plastic film fragments to vibrate and remove impurities from the surface of the plastic film fragments, but also breaks up the plastic film fragments that are piled together, which further helps to remove impurities and clean the plastic film fragments.

[0009] Preferably, the spray assembly includes a strip nozzle and a water pump. The strip nozzle is fixedly installed in the middle of the top of the top cover. The outlet of the bottom of the strip nozzle penetrates the top of the top cover and extends into it. The water pump is fixedly installed at the bottom of the surface of the cleaning tank. A right-angle pipe is installed at the water inlet at the bottom of the water pump. A flexible hose connects the water outlet at the top of the water pump and the strip nozzle. Using the suction of the water pump and connected by the right-angle pipe, some water inside the cleaning tank is drawn out and, connected by the flexible hose, enters the strip nozzle and is sprayed from the outlet of the strip nozzle into the interior of the top cover to wash the surface of the plastic film fragments.

[0010] Preferably, the liquid outlet at the bottom of the strip nozzle is conical, there are two strip nozzles, and the two strip nozzles are symmetrically installed along the central axis in the middle of the top cover. The end of the right-angle tube away from the water pump passes through the cleaning tank and extends into its interior.

[0011] Preferably, a film fragment pressing mechanism is installed on the side of the inner cavity of the cleaning tank. The film fragment pressing mechanism includes a support shaft and a power source. The two ends of the support shaft are rotatably installed on the inner wall of the cleaning tank. The power source is fixedly installed on the side of the surface of the cleaning tank. A rotating wheel is fixedly connected to the outer circular surface of the support shaft near the inner wall of the cleaning tank. A conveyor belt is installed on the surface of the rotating wheel. A pressing plate is hinged to the surface of the conveyor belt. A support spring is fixedly connected between the surface of the pressing plate and the surface of the conveyor belt. By rotating the output end of the power source, the support shaft can be driven to rotate. With the connection of the rotating wheel, the conveyor belt runs and drives the pressing plate to circulate. When the pressing plate reaches the top and the conveyor belt continues to run, the pressing plate moves downward in a horizontal state, pressing down the plastic film fragments floating on the liquid surface, so that the plastic film fragments are in full contact with the water, and the plastic film fragments can be soaked in the water.

[0012] Preferably, the support shaft is installed horizontally, one end of the support shaft passes through the cleaning tank and extends to its outside, and the end of the support shaft extending to the outside of the cleaning tank is fixedly installed to the output end of the power source through a coupling. There are four support shafts, and the four support shafts are evenly distributed on the side of the inner cavity of the cleaning tank.

[0013] As the conveyor belt drives the pressure plate to operate continuously, the pressure plate comes into contact with the water. As the pressure plate moves downward, it experiences the reverse resistance of the water, causing it to rotate and adjust its angle. The supporting spring is compressed, and the pressure plate tilts, which lifts the plastic film fragments that were originally below the pressure plate upward and allows them to be washed again by the elastic brush.

[0014] Preferably, the pressure plate is evenly installed on the surface of the conveyor belt, and the support spring is arc-shaped.

[0015] Preferably, an auxiliary mechanism is installed at the bottom of the inner cavity of the cleaning tank. This auxiliary mechanism includes a U-shaped support frame. The bottom of the U-shaped support frame is fixedly installed to the side of the bottom of the inner cavity of the cleaning tank using screws. A swing plate is rotatably installed on the top of the U-shaped support frame. The swing plate is installed at an angle, and its top extends to the bottom of the pressure plate. A mesh is fixedly connected to the middle of the surface of the swing plate, and a secondary plate is fixedly connected to the bottom of the surface of the swing plate. The pressure plate is continuously driven by a conveyor belt. As the pressure plate moves downward, it contacts the top of the swing plate, causing the top of the swing plate to be subjected to downward pressure. Supported by the U-shaped support frame, the swing plate drives the auxiliary plate to rotate and adjust its angle. The auxiliary plate moves obliquely upward, and the pressure plate separates from the top of the swing plate, causing the pressure on the swing plate to disappear. Utilizing the eccentric installation of the swing plate, and under the weight of the swing plate and the auxiliary plate, the swing plate drives the auxiliary plate to rotate in the opposite direction to reset. This reciprocating swinging motion agitates the water in the cleaning tank, keeping the water in a dynamic state. This facilitates the upward floating of plastic film fragments suspended in the water. When the swing plate swings, the water can pass through the mesh, reducing the resistance of the water to the swing plate and helping the swing plate drive the auxiliary plate to swing smoothly back and forth.

[0016] Preferably, there are two U-shaped support frames, and the two U-shaped support frames are symmetrically installed along the swing plate. The sub-plate is installed at an angle and is evenly distributed at the bottom end of the swing plate surface.

[0017] This invention provides a novel friction cleaning device for recycling plastic film. It has the following beneficial effects: I. This novel friction cleaning equipment for plastic film recycling utilizes the contraction of the hydraulic rod's telescopic end to apply a pulling force to the top cover, causing the top cover to move the entire debris cleaning mechanism downwards. The top cover seals the opening at the top of the cleaning tank, preventing water splashing during the cleaning of plastic film fragments. Furthermore, the extension of the hydraulic rod's telescopic end applies an upward pushing force to the top cover, causing it to move the debris cleaning mechanism upwards. The top cover then separates from the top of the cleaning tank, opening it. Adjusting the height of the top cover facilitates feeding and removing materials from the cleaning tank.

[0018] II. This novel friction cleaning equipment for recycling plastic film uses a top cover that fits the top of the cleaning tank. The bottom of the top cover matches the top of the cleaning tank. The separators are evenly distributed on the outer surface of the first rotating shaft, which separates the plastic film fragments floating on the liquid surface. This prevents the accumulation of a large number of film fragments and helps with subsequent cleaning of the film fragments.

[0019] III. This novel friction cleaning device for recycling plastic film utilizes the rotation of the driver output to drive the first rotating shaft to rotate, causing the separating disc to rotate along with the first rotating shaft. The rotation of the separating disc can drive the pull hook to rotate in a circle, hooking up the plastic film fragments floating on the liquid surface and separating the plastic film fragments that are stuck together. Furthermore, since the pull hook is made of rubber, it has good flexibility, and the pull hook makes flexible contact with the plastic film fragments, which is not likely to damage the plastic film fragments.

[0020] IV. This novel friction cleaning equipment for plastic film recycling utilizes a separator plate driven by a first rotating shaft to rotate, causing an elastic brush to rotate as well. The elastic brush brushes remove impurities from the surface of the plastic film fragments, and under the influence of friction, the impurities attached to the surface of the plastic film fragments are washed away, thereby achieving friction cleaning.

[0021] V. This novel friction cleaning equipment for recycling plastic film drives the second rotating shaft to rotate through the output end of the driver, causing the beating plate to rotate together with the second rotating shaft. The beating plate will beat on the plastic film fragments, which not only causes the plastic film fragments to vibrate and remove impurities from the surface of the plastic film fragments, but also breaks up the accumulated plastic film fragments, further facilitating the cleaning of the plastic film fragments.

[0022] VI. This novel friction cleaning equipment for recycling plastic film utilizes the suction of a water pump and, through a right-angle pipe connection, draws out some water from the cleaning tank. Through a hose connection, the water enters a strip nozzle and is sprayed from the nozzle's outlet into the top cover to wash the surface of the plastic film fragments.

[0023] VII. This novel friction cleaning equipment for recycling plastic film utilizes the rotation of the power source output to drive the support shaft to rotate. With the connection of the rotating wheel, the conveyor belt rotates and drives the pressure plate to circulate. When the pressure plate reaches the top, under the continuous operation of the conveyor belt, the pressure plate moves downward in a horizontal state, pressing down the plastic film fragments floating on the liquid surface. This allows the plastic film fragments to fully contact the water, thus soaking the plastic film fragments in the water.

[0024] 8. This new friction cleaning equipment for recycling plastic film involves a conveyor belt driving a pressure plate to operate continuously. The pressure plate comes into contact with water and moves downwards, causing it to be subjected to the reverse resistance of the water. This causes the pressure plate to rotate and adjust its angle, while the supporting spring is compressed, resulting in the pressure plate tilting. This allows the plastic film fragments that were originally below the pressure plate to float upwards and be brushed again by the elastic brush.

[0025] 9. This novel friction cleaning equipment for plastic film recycling utilizes a pressure plate to press down on a swing plate, causing the swing plate to rotate and adjust its angle. The swing plate moves obliquely upward, and as the pressure plate separates from the top of the swing plate, the pressing force on the swing plate disappears. Furthermore, the swing plate is eccentrically mounted, and under the weight of the swing plate and the swing plate itself, the swing plate drives the swing plate to rotate in the opposite direction to reset. This reciprocating swing agitates the water in the cleaning tank, keeping the water constantly dynamic. This facilitates the upward floating of plastic film fragments suspended in the water. When the swing plate is swinging, the water can pass through the mesh, reducing the resistance of the water to the swing plate and helping the swing plate drive the swing plate to swing smoothly back and forth.

[0028] 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.

[0029] First embodiment, such as Figures 1 to 6 As shown, the present invention provides a technical solution: A novel friction cleaning device for recycling plastic film includes: A cleaning tank 1, and a hydraulic rod 2 fixedly installed on the side of the surface of the cleaning tank 1. A drain pipe 3 is installed on the side of the bottom of the cleaning tank 1. A top cover 4 is fixedly connected to the telescopic end of the hydraulic rod 2. The operator activates hydraulic rod 2 to begin operation. By retracting the telescopic end of hydraulic rod 2, a pulling force is applied to the top cover 4, causing the top cover 4 to move the debris cleaning mechanism 5 downwards. The top cover 4 covers the top of the cleaning tank 1, sealing the opening at the top of the cleaning tank 1. This prevents water from splashing out when cleaning plastic film fragments. Furthermore, by extending the telescopic end of hydraulic rod 2, an upward pushing force is applied to the top cover 4, causing the top cover 4 to move the debris cleaning mechanism 5 upwards. The top cover 4 separates from the top of the cleaning tank 1 and is opened. The height of the top cover 4 can be adjusted to facilitate the feeding and retrieval of materials from the cleaning tank 1.

[0030] The debris cleaning mechanism 5 includes a first rotating shaft 51, a driver 52, and a second rotating shaft 53. The first rotating shaft 51 is rotatably mounted on the side of the inner cavity of the top cover 4. The driver 52 is fixedly mounted on the end of the surface of the top cover 4. The second rotating shaft 53 is rotatably mounted in the middle of the top of the inner cavity of the top cover 4. A separator plate 54 is fixedly connected to the outer circular surface of the first rotating shaft 51, and the separator plates 54 are evenly distributed on the outer circular surface of the first rotating shaft 51. The separator plates 54 are evenly distributed along the axial direction of the first rotating shaft 51. A toggle hook 55 is fixedly connected to the outer edge of the separator plate 54. The annular surface of the separator plate 54... An elastic brush 56 is fixedly connected to the first rotating shaft 51, and the elastic brush 56 is evenly distributed on the annular surface of the separator plate 54. A beater plate 57 is fixedly connected to the outer circular surface of the second rotating shaft 53. A spray assembly 58 is installed between the top of the top cover 4 and the bottom of the surface of the cleaning tank 1. The top cover 4 covers the top of the cleaning tank 1, and the bottom of the top cover 4 matches the top of the cleaning tank 1. The separator plate 54 is evenly distributed on the outer circular surface of the first rotating shaft 51, so that the separator plate 54 separates the plastic film fragments floating on the liquid surface, making it less likely for a large number of film fragments to accumulate, which helps to clean the film fragments later.

[0031] One end of the first rotating shaft 51, one end of the second rotating shaft 53, and the output end of the driver 52 are fixedly installed by a coupling. The striking plates 57 are evenly distributed on the outer surface of the second rotating shaft 53, and the material of the striking plates 57 is rubber.

[0032] The operator turns on the driver 52 to start operation. The rotation of the output end of the driver 52 drives the first rotating shaft 51 to rotate, so that the separator 54 rotates together with the first rotating shaft 51. The rotation of the separator 54 can drive the pull hook 55 to rotate in a circle, hooking up the plastic film fragments floating on the liquid surface, separating the plastic film fragments that are stuck together. Since the pull hook 55 is made of rubber, it has good flexibility and makes flexible contact with the plastic film fragments, so it is not easy to damage the plastic film fragments.

[0033] The lever hooks 55 are evenly distributed on the outer edge of the separator plate 54. The lever hooks 55 are arc-shaped and made of rubber.

[0034] The separator 54 is driven to rotate by the first rotating shaft 51, which causes the elastic brush 56 to rotate as well. The elastic brush 56 brushes away debris from the surface of the plastic film fragments, and under the influence of friction, the debris attached to the surface of the plastic film fragments is washed away, thereby achieving friction cleaning.

[0035] The second rotating shaft 53 is driven to rotate by the output of the driver 52, so that the beating plate 57 rotates together with the second rotating shaft 53. The beating plate 57 will beat on the plastic film fragments, which can not only make the plastic film fragments vibrate and remove the impurities on the surface of the plastic film fragments, but also break up the plastic film fragments that are piled together, which further helps to remove impurities and clean the plastic film fragments.

[0036] The spray assembly 58 includes a strip nozzle 581 and a water pump 582. The strip nozzle 581 is fixedly installed in the middle of the top of the top cover 4. The liquid outlet at the bottom of the strip nozzle 581 penetrates the top of the top cover 4 and extends into its interior. The water pump 582 is fixedly installed at the bottom of the surface of the cleaning tank 1. A right-angle pipe 583 is installed at the water inlet at the bottom of the water pump 582. A hose 584 connects the water outlet at the top of the water pump 582 and the strip nozzle 581. When the operator turns on the water pump 582, the suction force of the water pump 582, connected by the right-angle pipe 583, draws out some water from inside the cleaning tank 1. With the connection of the hose 584, the water enters the strip nozzle 581 and is sprayed from the liquid outlet of the strip nozzle 581 into the interior of the top cover 4 to wash the surface of the plastic film fragments.

[0037] The liquid outlet at the bottom of the strip nozzle 581 is conical and funnel-shaped. There are two strip nozzles 581, and the two strip nozzles 581 are symmetrically installed along the central axis in the middle of the top cover 4. The end of the right-angle tube 583 away from the water pump 582 passes through the cleaning tank 1 and extends into its interior.

[0038] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 8 As shown: A film fragment pressing mechanism 6 is installed on the side of the inner cavity of the cleaning tank 1. The film fragment pressing mechanism 6 includes a support shaft 61 and a power source 62. The two ends of the support shaft 61 are rotatably mounted to the inner wall of the cleaning tank 1. The power source 62 is fixedly installed on the side of the surface of the cleaning tank 1. A rotating wheel 63 is fixedly connected to the outer circumference of the support shaft 61 near the inner wall of the cleaning tank 1. A conveyor belt 64 is installed on the surface of the rotating wheel 63. A pressing plate 65 is hinged to the surface of the conveyor belt 64. A support spring 6 is fixedly connected between the surface of the pressing plate 65 and the surface of the conveyor belt 64. 6. The operator turns on the power source 62 to start working. The rotation of the output end of the power source 62 drives the support shaft 61 to rotate. With the connection of the rotating wheel 63, the conveyor belt 64 runs and drives the pressure plate 65 to run in a cycle. When the pressure plate 65 moves to the top, with the continuous operation of the conveyor belt 64, the pressure plate 65 moves downward in a horizontal state, which can press down the plastic film fragments floating on the liquid surface, so that the plastic film fragments are in full contact with the water and soaked in the water.

[0039] The support shaft 61 is installed horizontally. One end of the support shaft 61 passes through the cleaning tank 1 and extends to its outside. The end of the support shaft 61 extending to the outside of the cleaning tank 1 is fixedly installed to the output end of the power source 62 through a coupling. There are four support shafts 61, and the four support shafts 61 are evenly distributed on the side of the inner cavity of the cleaning tank 1. As the conveyor belt 64 drives the pressure plate 65 to rotate continuously, the pressure plate 65 comes into contact with the water. By continuously moving the pressure plate 65 downward, the pressure plate 65 is subjected to the reverse resistance of the water, which causes the pressure plate 65 to rotate and adjust its angle. The support spring 66 is compressed, and the pressure plate 65 is tilted. This allows the plastic film fragments that were originally below the pressure plate 65 to float upward and be brushed again by the elastic brush 56.

[0040] The pressure plate 65 is evenly installed on the surface of the conveyor belt 64, and the supporting spring 66 is arc-shaped.

[0041] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 1 to 9 As shown: An auxiliary mechanism 7 is installed at the bottom of the inner cavity of the cleaning tank 1. The auxiliary mechanism 7 includes a U-shaped support frame 71. The bottom of the U-shaped support frame 71 is fixedly installed to the side of the bottom of the inner cavity of the cleaning tank 1 by screws. A swing plate 72 is rotatably installed on the top of the U-shaped support frame 71. The swing plate 72 is installed at an angle, and the top of the swing plate 72 extends to the bottom of the pressure plate 65. A partition net 73 is fixedly connected to the middle of the surface of the swing plate 72. A sub-plate 74 is fixedly connected to the bottom of the surface of the swing plate 72. The pressure plate 65 is driven by the conveyor belt 64 to operate continuously. As the pressure plate 65 moves downward, it contacts the top of the swing plate 72, so that the top of the swing plate 72 is subjected to downward pressure. Supported by 1, the swing plate 72 drives the auxiliary plate 74 to rotate and adjust the angle. The auxiliary plate 74 moves obliquely upward. As the pressure plate 65 separates from the top of the swing plate 72, the pressing force on the swing plate 72 disappears. With the swing plate 72 being eccentrically installed, and under the action of the weight of the swing plate 72 and the auxiliary plate 74, the swing plate 72 drives the auxiliary plate 74 to rotate in the opposite direction to reset. By swinging back and forth in this way, the water in the cleaning tank 1 can be stirred, so that the water is always in a dynamic state, which makes it easier for the plastic film fragments suspended in the water to float upward. When the swing plate 72 is swinging, the water can pass through the partition net 73, reducing the resistance of the water to the swing plate 72 and helping the swing plate 72 to drive the auxiliary plate 74 to swing back and forth smoothly.

[0042] There are two U-shaped support frames 71, and the two U-shaped support frames 71 are symmetrically installed along the swing plate 72. The sub-plate 74 is installed at an angle and is evenly distributed on the bottom end of the surface of the swing plate 72.

[0043] In use, the extension of the telescopic end of the hydraulic rod 2 first applies an upward pushing force to the top cover 4, causing the top cover 4 to move the debris cleaning mechanism 5 upward, separating the top cover 4 from the top of the cleaning tank 1, opening the top cover 4, injecting an appropriate amount of clean water into the cleaning tank 1, and placing the plastic film to be cleaned into the cleaning tank 1. At this time, the staff will start the hydraulic rod 2 to work. By contracting the extension end of the hydraulic rod 2, a pulling force can be applied to the top cover 4, which will cause the top cover 4 to move the debris cleaning mechanism 5 downward as a whole. The top cover 4 will cover the top of the cleaning tank 1 to seal the opening at the top of the cleaning tank 1. Furthermore, by using the separator 54 evenly distributed on the outer surface of the first rotating shaft 51, the separator 54 separates the plastic film fragments floating on the liquid surface, making it less likely for a large number of film fragments to accumulate, which helps to clean the film fragments later. At the same time, the staff turns on the driver 52 to start working. The rotation of the output end of the driver 52 can drive the first rotating shaft 51 to rotate, so that the separator 54 will rotate together with the first rotating shaft 51. The rotation of the separator 54 can drive the pull hook 55 to rotate in a circle, hooking up the plastic film fragments floating on the liquid surface, so that the plastic film fragments stuck together are separated. Moreover, since the pull hook 55 is made of rubber, it has good flexibility. The pull hook 55 makes flexible contact with the plastic film fragments, and it is not easy to damage the plastic film fragments. The separator 54 is driven to rotate by the first rotating shaft 51, which causes the elastic brush 56 to rotate as well. The elastic brush 56 brushes away debris from the surface of the plastic film fragments, and under the influence of friction, the debris attached to the surface of the plastic film fragments is washed away, thereby achieving friction cleaning. The second rotating shaft 53 is driven to rotate by the output of the driver 52, so that the beater 57 will rotate together with the second rotating shaft 53. The beater 57 will beat on the plastic film fragments, which can not only make the plastic film fragments vibrate and cause the impurities on the surface of the plastic film fragments to fall off, but also break up the plastic film fragments that are piled together, which further helps to remove impurities and clean the plastic film fragments. The staff turned on the water pump 582 and used its suction power to draw out some water from the cleaning tank 1 through the connection of the right-angle pipe 583. Through the connection of the hose 584, the water entered the strip nozzle 581 and was sprayed from the outlet of the strip nozzle 581 into the interior of the top cover 4 to wash the surface of the plastic film fragments. The staff then turns on the power source 62. The rotation of the output end of the power source 62 drives the support shaft 61 to rotate. With the connection of the rotating wheel 63, the conveyor belt 64 rotates and drives the pressure plate 65 to circulate. When the pressure plate 65 reaches the top, it moves downward in a horizontal state under the continuous operation of the conveyor belt 64. This presses down the plastic film fragments floating on the liquid surface, allowing the plastic film fragments to fully contact the water and soak them.

[0044] As the conveyor belt 64 drives the pressure plate 65 to operate continuously, the pressure plate 65 comes into contact with the water. The pressure plate 65 moves downward continuously, causing the pressure plate 65 to be subjected to the reverse resistance of the water, which causes the pressure plate 65 to rotate and adjust its angle. The support spring 66 is compressed, and the pressure plate 65 is tilted. This allows the plastic film fragments that were originally below the pressure plate 65 to float upward and be washed again by the elastic brush 56. Furthermore, the pressure plate 65 is continuously driven by the conveyor belt 64. As the pressure plate 65 moves downward, it contacts the top of the swing plate 72, causing the top of the swing plate 72 to be subjected to downward pressure. Supported by the U-shaped support frame 71, the swing plate 72 drives the auxiliary plate 74 to rotate and adjust its angle. The auxiliary plate 74 moves obliquely upward. As the pressure plate 65 separates from the top of the swing plate 72, the pressure on the swing plate 72 disappears. Utilizing the eccentric installation of the swing plate 72, and under the weight of the swing plate 72 and the auxiliary plate 74, the swing plate 72 drives the auxiliary plate 74 to rotate in the opposite direction to reset. This reciprocating swinging motion agitates the water in the cleaning tank 1, keeping the water in a dynamic state. This facilitates the upward floating of plastic film fragments suspended in the water. When the swing plate 72 is swinging, the water can pass through the partition net 73, reducing the resistance of the water to the swing plate 72 and helping the swing plate 72 drive the auxiliary plate 74 to swing smoothly back and forth.
