Description

Technical Field

[0001] This invention relates to the field of plastic waste recycling technology, specifically to a plastic waste recycling and utilization equipment. Background Technology

[0002] Plastic materials, with their advantages of being lightweight, corrosion-resistant, inexpensive, and easy to mold, are widely used in many fields such as industrial production, daily life, packaging, and logistics. As a result, the amount of plastic waste generated has been increasing year by year. Plastic waste has an extremely long natural degradation cycle, and indiscriminate disposal will cause soil and water pollution, leading to serious ecological and environmental problems. At the same time, plastic is a recyclable resource. Recycling and reusing waste plastics can reduce environmental pollution, save virgin plastic raw materials, and reduce production energy consumption, which is in line with the development concept of green environmental protection and circular economy. Therefore, plastic waste recycling and processing equipment has become a key supporting equipment in the plastic products industry chain. Existing plastic waste recycling equipment still has the following shortcomings in actual use: 1. Low crushing efficiency and easy clogging: When traditional crushers process lightweight, thin-walled plastic waste (such as plastic bottles and sheets), the material is prone to accumulate and bridge above the crushing roller, resulting in poor material feeding or even clogging. In addition, existing equipment lacks an effective pressing mechanism, and the waste material does not make sufficient contact with the crushing roller, which easily leads to "virtual crushing" and affects the normal crushing process. 2. Poor cleaning effect: Broken plastic fragments often have impurities such as mud, sand and oil adhering to their surface. Existing cleaning tanks mostly use static soaking or simple stirring, which makes it difficult to fully wet the lightweight plastic fragments floating on the water surface and cannot effectively remove the stubborn stains attached to their surface, resulting in incomplete cleaning. 3. Simple feeding structure, prone to secondary pollution: During the retrieval process, wet waste after washing is easily stuck to the filter screen due to surface tension and electrostatic adsorption, resulting in poor feeding. At the same time, traditional equipment usually uses continuous overflow or simple retrieval methods, which cannot effectively achieve solid-liquid separation, resulting in a large amount of water being carried out, which not only wastes water resources, but also easily causes on-site environmental pollution, making it difficult to meet actual use needs. Summary of the Invention

[0003] The purpose of this invention is to provide a plastic waste recycling device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a plastic waste recycling device, including a support frame, a cleaning tank fixed on the support frame, a drain valve installed on the left side of the cleaning tank, a crushing box fixed on the left side of the upper end face of the cleaning tank, a crushing mechanism installed on the crushing box, the crushing mechanism being used for crushing plastic waste and assisting in pressing the material, a cleaning component for cleaning plastic waste installed on the cleaning tank, and a feeding component installed on the right side of the cleaning component on the cleaning tank, the feeding component being used to achieve intermittent feeding of plastic waste.

[0005] Preferably, inclined guide plates are symmetrically fixed inside the crushing box, and a fixing plate is fixed at the top of the crushing box. The inclined guide plates can guide the plastic waste, thus providing a basic guarantee for the subsequent crushing of plastic waste.

[0006] Preferably, the crushing mechanism includes a bracket fixed to the washing tank, and a first motor is fixed on the bracket. The output end of the first motor is fixed with a drive gear, and the drive gear is meshed with one of the driven gears. The driven gears are symmetrically fixed on the crushing rollers, and the crushing roller bearings are connected inside the crushing box. The driven gears at the ends of the two crushing rollers are meshed. The crushing rollers are located below the guide plate. The first motor drives the drive gear to rotate. With the meshing transmission between the drive gear and the driven gear and the meshing transmission between the two driven gears, the two crushing rollers can rotate in opposite directions, thereby crushing the plastic waste guided by the guide plate.

[0007] Preferably, a cam shaft is also fixed on the driven gear, and the cam shaft is slidably connected to the slide plate. The slide plate is symmetrically fixed on the movable frame, and slide rods are symmetrically fixed on the movable frame. The slide rods are slidably connected to the fixed plate. The driven gear drives the cam shaft to rotate. With the sliding connection between the cam shaft and the slide plate, the slide plate can move up and down in an orderly manner. With the sliding guide effect between the slide rod and the fixed plate, the stability of the slide plate movement can be ensured.

[0008] Preferably, a cylinder is fixed to the lower end face of the slide bar, and a crossbar is fixed on the cylinder. Material-pulling plates are fixed at equal intervals on the crossbar. The slide bar is driven to move up and down by the sliding groove plate, which can synchronously drive the cylinder, crossbar and material-pulling plates to move up and down in an orderly manner. Through the action of the material-pulling plates, the plastic waste accumulated in the crushing box can be disturbed, thereby avoiding the accumulation of plastic waste and affecting the normal feeding function.

[0009] Preferably, the cylinder and the vertical rod are slidably connected, and one end of the vertical rod is connected to the cylinder by a spring, while the other end of the vertical rod is fixed with a pressure plate. The upper surface of the pressure plate has an inverted "V" shape. The pressure plate is located directly above the middle position of the two crushing rollers. When the cylinder moves up and down, it synchronously drives the vertical rod and the pressure plate to move up and down. Through the action of the pressure plate and the elasticity of the spring, the pressure plate can generate a downward flexible squeezing force on the plastic waste below, so that the plastic waste can better contact the crushing rollers for crushing and ensure the crushing quality of the plastic waste.

[0010] Preferably, the cleaning assembly includes a second motor fixed to the cleaning tank, and a circular roller is fixed to the output end of the second motor. The circular roller bearing is connected inside the cleaning tank. At the same time, horizontal plates are fixed at equal intervals on the circular roller. The second motor can drive the circular roller and the horizontal plates to rotate. Through the rotation of the horizontal plates, a turbulence effect can be achieved, and the suspended plastic waste can be pressed down into the water, thereby effectively improving the cleaning effect of the plastic waste.

[0011] Preferably, the horizontal plate is symmetrically fixed with protruding plates at the front and back, and the protruding plates are slidably connected to the lever. The lever is symmetrically fixed on the rotating shaft at the front and back, and the rotating shaft is rotatably connected to the cleaning tank. A torsion spring is connected between the rotating shaft and the cleaning tank, and striking plates are fixed at equal intervals on the rotating shaft. The rotation of the horizontal plate can drive the protruding plates to rotate. Combined with the sliding action between the protruding plates and the lever and the elastic action of the torsion spring, the rotating shaft can be made to swing back and forth, thereby driving the striking plates to swing back and forth. Through the swinging action of the striking plates, the plastic waste suspended on the water surface can be struck, thereby effectively removing the mud and debris and other impurities adhering to the surface of the plastic waste, thus effectively ensuring the cleaning quality of the clinker waste.

[0012] Preferably, the feeding assembly includes a feeding frame with a mesh opening on its lower end face that is rotatably connected to the cleaning tank. A torsion spring connects the feeding frame to the cleaning tank, and symmetrically fixed front and rear paddle plates are fixed on the feeding frame. The paddle plates are slidably connected to the convex plates. An arc panel is fixed on the lower side of the feeding frame and is slidably connected to the baffle plate. The baffle plate is fixed inside the cleaning tank. Through the sliding action between the paddle plates and the convex plates and the elastic action of the torsion spring, the feeding frame can be reciprocated. Through the oscillation action of the feeding frame, the intermittent feeding of plastic waste can be achieved. Furthermore, through the sliding action between the arc panel and the baffle plate, the plastic waste can be prevented from entering the right side of the baffle plate and affecting the normal feeding of subsequent materials.

[0013] Preferably, the feeding frame and the pusher plate are slidably connected, and counterweights are fixed on the pusher plate at equal intervals. The pusher plate and the guide rod are also slidably connected, and the guide rod is symmetrically fixed on the feeding frame. When the feeding frame swings back and forth, the counterweights can cause the pusher plate to move left and right in an orderly manner on the feeding frame. Combined with the sliding guidance between the pusher plate and the guide rod, the stability of the pusher plate's movement can be ensured. Through the movement of the pusher plate, it can both block the plastic waste when the feeding frame is carrying it, ensuring the normal retrieval of the plastic waste by the feeding frame, and push the plastic waste on the feeding frame when the feeding frame is tilted, ensuring the normal feeding of the plastic waste.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This plastic waste recycling equipment adopts a linkage crushing mechanism. The driven gear rotates to drive the cam shaft and slide plate to move up and down, which in turn drives the movable frame and slide rod to move synchronously. The pushing plate can continuously disturb the plastic waste accumulated in the crushing box, breaking up material accumulation and bridging, and ensuring that the material falls evenly and orderly. The inverted V-shaped pressure plate, with the elasticity of the spring, can flexibly press down the falling material, allowing the plastic waste to fully fit the crushing roller, avoiding the problem of material suspension and incomplete crushing. At the same time, the crushing structure with the double crushing rollers meshing and rotating in opposite directions can achieve efficient and fine crushing of plastic waste, completely solving the problems of incomplete crushing, machine jamming and poor operation continuity of traditional equipment, and greatly improving the stability of crushing and processing and the qualified rate of finished products. 2. This plastic waste recycling equipment uses a cleaning component that achieves a dual function through the rotation of a horizontal plate. First, the horizontal plate presses the floating plastic into the water, ensuring complete immersion of the material and increasing the water-material contact area. Second, the convex plate on the horizontal plate works in conjunction with the lever on the rotating shaft to drive the striking plate to oscillate at high frequency. The striking action generates a strong water shock wave, effectively removing stubborn impurities such as mud and sand adhering to the plastic surface. This effectively solves the technical problem of lightweight plastics being difficult to immerse and clean. 3. This plastic waste recycling equipment features a feeding component linked to the cleaning assembly. The feeding frame oscillates periodically thanks to the rotational power of the convex plate, eliminating the need for an additional drive mechanism. This results in lower energy consumption and a more streamlined structure. The feeding frame automatically switches between left and right tilt positions. Combined with the limiting and blocking functions of the arc panel and baffle plate, it accurately collects the cleaned plastic granules, preventing material spillage. Simultaneously, the pusher plate with counterweight automatically slides according to the feeding frame's posture, automatically pushing material out when tilted and automatically returning to its original position when reset. This effectively solves the problem of wet plastic granules adhering to the feeding structure and clogging the discharge port. The entire process achieves intermittent automatic material retrieval, pushing, and discharge without manual intervention, significantly reducing maintenance costs and improving the equipment's automation level and continuous operation capability.

[0017] 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.

[0018] Please see Figures 1-7 The present invention provides a technical solution: a plastic waste recycling device, including a support frame 1, a washing tank 2 fixed on the support frame 1, a drain valve port 3 installed on the left side of the washing tank 2, a crushing box 4 fixed on the left side of the upper end face of the washing tank 2, a crushing mechanism 5 installed on the crushing box 4, the crushing mechanism 5 is used for crushing plastic waste and assisting in pressing the material, a washing component 6 for washing plastic waste is installed on the washing tank 2, and a feeding component 7 installed on the right side of the washing component 6 is provided on the washing tank 2, the feeding component 7 is used to realize the intermittent feeding of plastic waste.

[0019] Inside the crushing box 4, inclined guide plates 401 are symmetrically fixed on the left and right sides, and a fixing plate 402 is fixed at the upper end of the crushing box 4; the crushing mechanism 5 includes a bracket 501 fixed on the washing tank 2, and a first motor 502 is fixed on the bracket 501. A drive gear 503 is fixed at the output end of the first motor 502, and the drive gear 503 is meshed with one of the driven gears 504. The driven gears 504 are symmetrically fixed on the crushing rollers 505, and the bearings of the crushing rollers 505 are connected inside the crushing box 4. The driven gears 504 at the ends of the two crushing rollers 505 are meshed, and the crushing rollers 505 are located below the guide plates 401; a cam shaft 506 is also fixed on the driven gear 504, and the cam shaft 506 is connected to... The chute plates 507 are slidably connected and are symmetrically fixed to the movable frame 508. The movable frame 508 is also symmetrically fixed with sliding rods 509. The sliding rods 509 are slidably connected to the fixed plate 402. A cylinder 510 is fixed to the lower end of the sliding rod 509. A horizontal bar 511 is fixed to the cylinder 510, and a material-pulling plate 512 is fixed at equal intervals on the horizontal bar 511. The cylinder 510 is slidably connected to the vertical rod 513. One end of the vertical rod 513 is connected to the cylinder 510 through a spring 514. The other end of the vertical rod 513 is fixed with a pressure plate 515. The upper end of the pressure plate 515 has an inverted "V" shaped structure. The pressure plate 515 is located directly above the middle position of the two crushing rollers 505. When using this plastic waste recycling equipment, such as Figures 1-7As shown, water is first injected into the washing tank 2 to clean the crushed plastic waste. Then, the plastic waste to be processed is put into the crushing box 4. Through the guiding action of the guide plate 401, the plastic waste can come into contact with the two crushing rollers 505. By starting the first motor 502, the drive gear 503 is driven to rotate counterclockwise. With the meshing transmission between the drive gear 503 and the driven gear 504 and the meshing transmission between the driven gears 504 at the ends of the two crushing rollers 505, the two crushing rollers 505 can rotate in opposite directions. Through the cooperation of the two crushing rollers 505, the plastic waste can be crushed and processed. When the driven gear 504 rotates, it synchronously drives the cam shaft 506 to rotate. Combined with the sliding action between the cam shaft 506 and the slide plate 507, the slide plate 507, the movable frame 508, and the slide rod 509 can move up and down in an orderly manner. Combined with the sliding guide action between the slide rod 509 and the fixed plate 402, the stability of the movable frame 508's up and down movement can be ensured. Through the movement of the slide rod 509, the cylinder 510, the crossbar 511, and the material-pushing plate 512 can be synchronously driven to move up and down in an orderly manner. Through the up and down movement of the material-pushing plate 512, the accumulated plastic waste in the crushing box 4 can be processed. The material is disturbed, which effectively prevents the accumulation of plastic waste in the crushing box 4 from affecting the normal feeding, thus ensuring the normal crushing of plastic waste. When the cylinder 510 moves up and down in an orderly manner, it can synchronously drive the pressure plate 515 to move up and down in an orderly manner. With the sliding action between the vertical rod 513 and the cylinder 510 and the elastic action of the spring 514, the pressure plate 515 can generate a flexible downward pressure force on the plastic waste below the pressure plate 515 each time it moves down, so that the plastic waste can better contact the crushing roller 505 for crushing, thus effectively ensuring the normal crushing of plastic waste. The cleaning assembly 6 includes a second motor 601 fixed to the cleaning tank 2, and a circular roller 602 is fixed to the output end of the second motor 601. The circular roller 602 is connected to the cleaning tank 2 by a bearing. At the same time, horizontal plates 603 are fixed at equal intervals on the circular roller 602. Convex plates 604 are symmetrically fixed on the horizontal plates 603. The convex plates 604 are slidably connected to the lever 605. The lever 605 is symmetrically fixed on the rotating shaft 606. The rotating shaft 606 is rotatably connected to the cleaning tank 2. A torsion spring is connected between the rotating shaft 606 and the cleaning tank 2. A striking plate 607 is fixed at equal intervals on the rotating shaft 606. like Figures 1-7As shown, the plastic waste crushed by the crushing mechanism 5 enters the washing tank 2 through the opening at the lower end of the crushing box 4. The second motor 601 drives the roller 602 to rotate counterclockwise, which in turn drives the horizontal plate 603 to rotate counterclockwise. The rotation of the horizontal plate 603 agitates the water in the washing tank 2, causing the crushed plastic waste to float and disperse from left to right within the washing tank 2. Simultaneously, the horizontal plate 603 rotates, driving the convex plate 604 to rotate. When the convex plate 604 contacts and slides against the lever 605, the rotating shaft 606 is forced to swing clockwise, causing the striking plate 607 to swing clockwise upwards. When the convex plate 604 separates from the lever 605, the torsion spring causes the rotating shaft 606 to swing clockwise upwards. The shaft 606 and the striking plate 607 rotate counterclockwise to reset. By swinging counterclockwise, the plastic waste suspended on the water surface in the cleaning tank 2 can be struck. The striking action can effectively remove foreign objects such as mud and sand adhering to the surface of the plastic waste, thereby effectively ensuring the cleaning quality of the plastic waste. During the rotation of the horizontal plate 603, when the horizontal plate 603 comes into contact with the plastic particles suspended on the liquid surface in the cleaning tank 2, the suspended plastic particles are pressed down to make the plastic particles completely immersed in the water. The horizontal plate 603 moves to the right side of the round roller 602 to facilitate subsequent feeding. By completely immersing the plastic particles in the water, the contact area between the plastic particles and the water can be effectively increased, further enhancing the cleaning effect of the plastic particles. The feeding assembly 7 includes a feeding frame 701 with a mesh opening on its lower end face that is rotatably connected to the cleaning tank 2. A torsion spring connects the feeding frame 701 to the cleaning tank 2. A lever 702 is symmetrically fixed on the feeding frame 701. The lever 702 is slidably connected to the protruding plate 604. An arc panel 706 is fixed on the lower side of the feeding frame 701. The arc panel 706 is slidably connected to the baffle plate 707, and the baffle plate 707 is fixed inside the cleaning tank 2. The feeding frame 701 is slidably connected to the pusher plate 703. A counterweight 704 is fixed at equal intervals on the pusher plate 703. The pusher plate 703 is slidably connected to the guide rod 705. The guide rod 705 is symmetrically fixed on the feeding frame 701. like Figures 1-7 As shown, the cleaned plastic granules move to the right side of the roller 602. Due to the blocking effect of the arc panel 706 and the baffle plate 707, the plastic granules are prevented from moving to the right side of the feeding frame 701 end face, ensuring the normal operation of subsequent feeding. Figures 1-7As shown, at this time, the feeding frame 701 is tilted with the left side lower than the right side, and the left end of the feeding frame 701 and the pusher plate 703 are completely submerged in water to ensure the normal retrieval and feeding of plastic waste after cleaning. During the counterclockwise rotation of the convex plate 604, when the convex plate 604 contacts and slides with the pusher plate 702, the feeding frame 701 is subjected to force and swings clockwise, thereby driving the pusher plate 703 to swing. Through the swinging of the feeding frame 701 and the pusher plate 703, the suspended plastic waste in the cleaning tank 2 can be retrieved. In addition, with the blocking effect of the pusher plate 703, the retrieved plastic particles can be prevented from slipping back into the cleaning tank 2. During the continuous swinging of the feeding frame 701, the current When the material frame 701 swings to a left-high, right-low position, the counterweight 704 causes the pusher plate 703 to slide to the right side of the material frame 701, thus pushing the plastic waste collected on the material frame 701 to the right for discharge and collection. This achieves automatic feeding of plastic waste and prevents wet plastic waste from sticking to the material frame 701 and affecting the normal feeding process. When the convex plate 604 separates from the pusher plate 702, the torsion spring causes the material frame 701 to swing back to a left-low, right-high tilted state. At this time, the pusher plate 703 automatically moves to the leftmost side of the material frame 701 under the gravity of the counterweight 704 to facilitate the next feeding.
