[0001] This utility model belongs to the field of polyamide recycling technology, and in particular relates to a device for recycling polyamide waste. Background Technology

[0002] Polyamide is a widely used high-performance plastic, commonly used in textiles, automobiles, and electronics. With the increasing use of polyamide products, the amount of waste generated is also increasing. If this waste is not treated properly, it will have a serious impact on the environment.

[0003] When waste is collected after being crushed, large and small pieces of waste are usually mixed together, which leads to inefficiency in subsequent recycling and waste of resources. At the same time, larger particles may hinder the further processing of smaller particles and reduce the overall recycling rate. To address this, we provide a device for recycling polyamide waste. Utility Model Content

[0004] The purpose of this invention is to provide a device for recycling polyamide waste. An eccentric wheel squeezes the filter plate, and then a telescopic spring resets the filter plate, causing it to shake continuously. This solves the problem that in existing waste collection methods, large and small pieces of waste are often mixed together after the waste has been fully crushed, which leads to inefficient subsequent recycling processes.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a device for recycling polyamide waste, including a box, a screening mechanism inside the box, and a multi-stage crushing mechanism inside the box.

[0007] The screening mechanism includes a first motor, the inner wall of the first motor is fixedly connected to the outer wall of the box, the bottom output shaft of the first motor is fixedly connected to a first rotating shaft through a coupling, an eccentric wheel is fixedly connected to the outer surface of the first rotating shaft, and a protective box is rotatably connected to the outer surface of the first rotating shaft.

[0008] A fixed shaft is fixedly connected to the outer wall of the protective box, and the outer wall of the fixed shaft is fixedly connected to the inner wall of the box. A second rotating shaft is rotatably connected inside the protective box. A second bevel gear is fixedly connected to the outer surface of the second rotating shaft. A scraper is fixedly connected to the bottom of the second rotating shaft. A first bevel gear is fixedly connected to the outer surface of the first rotating shaft. A fixed block is fixedly connected to the inner wall of the box. A telescopic rod is fixedly connected to the top of the fixed block. A telescopic spring is sleeved on the outer surface of the telescopic rod. A filter plate is fixedly connected to the top of the telescopic spring.

[0009] Furthermore, there are two eccentric wheels, the bottom of the filter plate is fixedly connected to the bottom of the telescopic rod, the first bevel gear meshes with the second bevel gear, the outer surface of the filter plate is slidably connected to the inner wall of the box, and the outer surface of the scraper is slidably connected to the top of the filter plate.

[0010] Furthermore, the multi-stage crushing mechanism includes a second motor, the inner wall of which is fixedly connected to the outer wall of the housing.

[0011] Furthermore, the bottom output shaft of the second motor is fixedly connected to a first rotating shaft via a coupling, and a first gear is fixedly connected to the outer surface of the first rotating shaft.

[0012] Furthermore, there are two first gears, which mesh with each other. A first crushing wheel is fixedly connected to the outer surface of the first rotating shaft, and a first pulley is fixedly connected to the outer surface of the first rotating shaft.

[0013] Furthermore, a belt is driven to the inner wall of the first pulley, and a second pulley is driven to the inner wall of the belt away from the first pulley. A second rotating shaft is fixedly connected to the inner wall of the second pulley.

[0014] Furthermore, a second gear is fixedly connected to the outer surface of the second rotating shaft. There are two second gears in total, and the two second gears mesh with each other. A second crushing wheel is fixedly connected to the outer surface of the second rotating shaft.

[0015] Furthermore, a first guide block is fixedly connected to the inner wall of the box, a second guide block is fixedly connected to the inner wall of the box, and a feed frame is fixedly connected to the top of the box.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting up eccentric wheels, allows waste material to fall onto the filter plate surface after secondary crushing. Then, the first motor is started, and the first rotating shaft drives the eccentric wheels on both sides to rotate in a circular motion. As the eccentric wheels rotate, the longer end of the eccentric wheel presses down on the filter plate. When the longer end of the eccentric wheel reaches the top, the telescopic spring drives the filter plate to reset. This process repeats, continuously shaking the waste material. Simultaneously, the rotation of the first rotating shaft also drives the first bevel gear to rotate, which in turn drives the scraper to rotate. Larger pieces of waste are left on the filter plate surface, while smaller pieces remain at the bottom of the chamber, thus achieving efficient waste separation, optimizing the waste treatment process, increasing resource recovery rate, reducing the need for manual intervention, and ultimately improving overall processing efficiency.

[0018] 2. This utility model, by setting up crushing wheels, allows for efficient graded crushing of waste materials. First, the second motor is started, causing the first rotating shaft to drive the first gear on its surface to rotate. This first gear then drives the adjacent first gear to rotate, and the two rotating shafts on both sides drive the first crushing wheels on their surfaces to rotate. A belt then drives the second pulley to rotate, which in turn drives the second rotating shaft to rotate. The second rotating shaft then drives the second gear on its surface to rotate, and the two rotating shafts on both sides drive the second crushing wheels on their surfaces to rotate. Waste materials can then be poured into the feed frame. The waste materials are then limited by the first guide block and fall into the center point of the two first crushing wheels on both sides for crushing. After the first crushing, the waste materials fall and are limited by the second guide block, falling into the center point of the two second crushing wheels on both sides for further crushing. This achieves efficient graded crushing of waste materials, ensuring that the waste materials are fully crushed at each stage, improving crushing efficiency, optimizing the overall operation process, and enhancing the operational reliability of the equipment.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 As shown, this utility model is a polyamide waste recycling device, including a box 101, a screening mechanism 1 inside the box 101, and a multi-stage crushing mechanism 2 inside the box 101.

[0030] The screening mechanism 1 includes a first motor 108. Starting the first motor 108 drives the first rotating shaft 107 to rotate. The first rotating shaft 107 then drives two eccentric wheels 106 on its surface to rotate in a circular motion. During this rotation, the eccentric wheels 106 regularly squeeze the filter plate 103, causing it to move downwards. When the eccentric wheels 106 leave the surface of the filter plate 103, the telescopic spring 114 pushes the filter plate 103 back to its original position. This process repeats continuously, causing the filter plate 103 to vibrate continuously. This effectively prevents clogging by polyamide waste, promotes full contact between the waste and the filter material, and enhances filtration efficiency. The inner wall of the first motor 108 is fixedly connected to the outer wall of the housing 101. The bottom output shaft of the first motor 108 passes through… A first rotating shaft 107 is fixedly connected via a coupling. An eccentric wheel 106 is fixedly connected to the outer surface of the first rotating shaft 107. A protective box 105 is rotatably connected to the outer surface of the first rotating shaft 107. The protective box 105 protects the first bevel gear 110 and the second bevel gear 111 inside from damage and jamming by waste materials. A fixed shaft 104 is fixedly connected to the outer wall of the protective box 105. The outer wall of the fixed shaft 104 is fixedly connected to the inner wall of the box body 101. A second rotating shaft 112 is rotatably connected inside the protective box 105. A second bevel gear 111 is fixedly connected to the outer surface of the second rotating shaft 112. A scraper 109 is fixedly connected to the bottom of the second rotating shaft 112. The first bevel gear 110 is fixedly connected to the outer surface of the first rotating shaft 107. The first bevel gear 110 rotates along with the first rotating shaft 107, thereby driving the second bevel gear 111 to rotate. This, in turn, causes the scraper 109 to continuously scrape the surface of the filter plate 103, effectively removing impurities and waste adhering to the filter plate 103, keeping the surface of the filter plate 103 clean, preventing clogging, and thus improving filtration efficiency. A fixing block 113 is fixedly connected to the inner wall of the housing 101, and a telescopic rod 115 is fixedly connected to the top of the fixing block 113. The telescopic rod 115 can limit the telescopic spring 114 to prevent displacement. The telescopic spring 114 is sleeved on the outer surface of the telescopic rod 115, and the filter plate 103 is fixedly connected to the top of the telescopic spring 114. The filter plate 103 can... Waste is screened to separate large and small pieces of waste for collection, thereby improving the efficiency of subsequent processing. A sliding door 102 is slidably connected to the inner wall of the housing 101. Through the two sliding doors 102 inside the housing 101, waste on the top of the filter plate 103 and waste at the bottom of the housing 101 can be collected. Two eccentric wheels 106 are provided. The bottom of the filter plate 103 is fixedly connected to the bottom of the telescopic rod 115. The first bevel gear 110 and the second bevel gear 111 mesh. The outer surface of the filter plate 103 is slidably connected to the inner wall of the housing 101. The outer surface of the scraper 109 is slidably connected to the top of the filter plate 103. The multi-stage crushing mechanism 2 includes a second motor 202. The inner wall of the second motor 202 is fixedly connected to the outer wall of the housing 101.

[0031] The bottom output shaft of the second motor 202 is fixedly connected to the first rotating shaft 203 via a coupling. The second motor 202 drives the first rotating shaft 203 to rotate, which in turn drives the first gear 209 on its surface to rotate. At this time, the first gear 209 drives another first gear 209 to rotate synchronously in the opposite direction. Subsequently, the two first rotating shafts 203 drive the first crushing wheel 205 on its surface to rotate, thereby crushing the waste material. The outer surface of the first rotating shaft 203 is fixedly connected to the first gear 209. There are two first gears 209 in total. The wheels 209 mesh with each other. The first crushing wheel 205 is fixedly connected to the outer surface of the first rotating shaft 203. The first pulley 210 is fixedly connected to the outer surface of the first rotating shaft 203. The inner wall of the first pulley 210 is connected to a belt 211. When the first rotating shaft 203 rotates, the belt 211 drives the first pulley 210 to rotate, thereby driving the second rotating shaft 207 to rotate synchronously. The end of the inner wall of the belt 211 away from the first pulley 210 is connected to a second pulley 212. The inner wall of the second pulley 212 is fixedly connected to the second rotating shaft 207.

[0032] A second gear 213 is fixedly connected to the outer surface of the second rotating shaft 207. The second rotating shaft 207 is driven by the belt 211, which causes the second rotating shaft 207 to drive the second gear 213 to rotate. At this time, the second gear 213 will drive the second gear 213 on the side to rotate in the opposite direction, thereby driving the second crushing wheels 208 on the surface of the second rotating shaft 207 on both sides to rotate, thus performing secondary crushing. There are two second gears 213, which mesh with each other. The second crushing wheels 208 are fixedly connected to the outer surface of the second rotating shaft 207. A first guide block 204 is fixedly connected to the inner wall of the box 101. The first guide block 204 and the second guide block 206 can limit the waste material, so that it always falls into the center point of the two first crushing wheels 205, thereby improving the crushing efficiency. The second guide block 206 is fixedly connected to the inner wall of the box 101. A feed frame 201 is fixedly connected to the top of the box 101.

[0033] One specific application of this embodiment is:

[0034] When waste needs to be crushed, the second motor 202 is started first. The second motor 202 then drives the first rotating shaft 203 to rotate, which in turn drives the first gear 209 on the surface to rotate. This first gear 209 then drives another first gear 209 to rotate, and the two first gears 209 rotate in opposite directions. Simultaneously, the rotation of the first rotating shafts 203 drives the first crushing wheel 205 on the surface to rotate. The rotation of the first rotating shafts 203 also drives the first pulley 210 on the surface to rotate, which in turn drives the belt 2 on the surface. 11 rotates, then belt 211 drives second pulley 212 to rotate, which in turn drives second rotating shaft 207 to rotate. Second rotating shaft 207 then drives second gear 213 on the surface to rotate. The two second gears 213 then rotate in opposite directions. At this time, the second rotating shafts 207 on both sides drive the second crushing wheels 208 on the surface to rotate. Waste material can then be poured into the feed frame 201. The waste material is then limited by first guide block 204 and falls into the center point of the first crushing wheels 205 on both sides for crushing. After the first crushing, the waste material falls and is limited by second guide block 206. The waste material falls into the center point of the second crushing wheel 208 on both sides for crushing. After the waste material is crushed for the second time, it falls onto the surface of the filter plate 103. Then, the first motor 108 is started, which drives the first rotating shaft 107 to rotate. The first rotating shaft 107 drives the eccentric wheels 106 on both sides to rotate in a circle. As the eccentric wheels 106 rotate, the longer end of the eccentric wheel 106 will press the filter plate 103 downward, and the telescopic spring 114 will be compressed. The telescopic rod 115 is responsible for limiting the movement. When the longer end of the eccentric wheel 106 moves to the top, the telescopic spring 114 will drive the filter plate 103 to return to its original position. In this process, the filter plate 103 continuously shakes the waste material. When the first rotating shaft 107 rotates, it also drives the first bevel gear 110 to rotate. Then, the first bevel gear 110 drives the second bevel gear 111 to rotate. Then, the second bevel gear 111 drives the second rotating shaft 112 to rotate. At this time, the second rotating shaft 112 drives the scraper 109 to rotate. When the filter plate 103 is reset, the scraper 109 scrapes its surface. Then, large pieces of waste are left on the surface of the filter plate 103, while small pieces of waste are at the bottom of the box 101. Then, the two sliding doors 102 can be opened to collect them.
