Description

Technical Field

[0001] This utility model relates to the field of plastic recycling technology, specifically to a crushing device for plastic recycling. Background Technology

[0002] Plastic recycling and crushing is the process of converting waste plastics into small particles or powders through physical treatments such as crushing and pulverizing. It aims to reduce environmental pollution, conserve resources and promote recycling. It typically involves steps such as collection, sorting, washing and crushing. The final product can be used as a recycled raw material to manufacture new plastic products or for other industrial uses.

[0003] In the existing technology, roller crushers are usually used to initially crush plastic raw materials. However, when the plastic raw materials occupy a large area, such as crushing plastic sheets, operators need to continuously support the plastic raw materials so that they are fed vertically into the roller crusher, which is quite labor-intensive. Therefore, a crushing device for plastic recycling is proposed to solve the above problems. Utility Model Content

[0016] 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.

[0017] like Figure 1-6 As shown, a plastic recycling crushing device includes a crusher 1, with a support mechanism 2 above the crusher 1. The support mechanism 2 includes two uprights 201. Each upright 201 has a support roller 202 rotatably connected to its upper and lower ends. A mounting rail 203 is fixedly connected to the lower end of the side of each upright 201 away from the support roller 202. The mounting rail 203 extends horizontally. An insert plate 204 is inserted into and slidably connected to the inner side of each mounting rail 203. A splash guard 205 is fixedly connected to the center of the surface of each insert plate 204. The other side of the splash guard 205 extends to the outside of the mounting rail 203. Figure 1 As shown, the splash guard 205 prevents shredded plastic fragments from flying out of the opening above the shredder 1.

[0018] Both uprights 201 have a first slider 206 fixedly connected to the bottom end on the same side. The surfaces of the two first sliders 206 respectively pass through and slide with pins 207, such as... Figure 4 As shown, each of the first sliders 206 has a through hole on its surface to accommodate the pin 207.

[0019] A second slider 208 is fixedly connected to the bottom surface of one of the uprights 201, at the end furthest from the first slider 206. Threaded shafts 210 are fixedly connected to both ends of the bottom surface of the second slider 208. A support plate 211 is connected through the outer sides of both threaded shafts 210. One side of the top surface of the support plate 211 abuts against the bottom surface of the second slider 208, and a groove 212 is formed on the other side of the top surface of the support plate 211. First nuts 213 are threaded onto the outer walls of the two threaded shafts 210, and the top surface of each first nut 213 abuts against the bottom surface of the support plate 211. Figure 6 As shown, after the first nut 213 is tightened on the outside of the threaded shaft 210, the first nut 213 supports the bottom of the support plate 211.

[0020] Another support 201 has a third slider 209 fixedly connected to its top surface and the end furthest from the first slider 206. A telescopic plate 214 is slidably connected through and slidably connected to the inner wall of the third slider 209. An elongated groove 215 is formed in the center of the surface of the telescopic plate 214. Both the telescopic plate 214 and the elongated groove 215 are aligned in the length direction. The telescopic plate 214 is L-shaped overall, and one end of the telescopic plate 214 extends to the outside of the third slider 209 and inserts into the inner side of the groove 212. Figure 6 As shown, the end of the telescopic plate 214 extends vertically downward, and the end of the telescopic plate 214 can be inserted into the groove 212.

[0021] A bolt 216 is connected through the top surface of the third slider 209, and the lower end of the bolt 216 is connected through the inner side of the elongated groove 215. A second nut 217 is threaded onto the outer wall of the bolt 216, and the top surface of the second nut 217 abuts against the bottom surface of the telescopic plate 214. Figures 5-6 As shown, the second nut 217, together with the third slider 209, clamps the telescopic plate 214.

[0022] The crusher 1 includes a crushing chamber 101. Servo motors 102 are fixedly installed at both ends of the outer wall of the crushing chamber 101. The output shafts of the servo motors 102 pass through the interior of the crushing chamber 101 and are fixedly connected to a crushing blade assembly 103. The crushing blade assembly 103 is supported and rotatably connected to the inner side of the crushing chamber 101. A discharge hopper 104 is fixedly installed on the bottom surface of the crushing chamber 101. Support legs 105 are fixedly connected to the outer side of the discharge hopper 104. A first extension rail 106 is fixedly connected to one side of the upper end of the outer wall of the crushing chamber 101, and a second extension rail 107 is fixedly connected to the other side of the upper end of the outer wall of the crushing chamber 101. Several positioning holes 108 are equidistantly opened on the top surface of the second extension rail 107. The inner side of the first extension rail 106 is slidably connected to a second slider 208 and a third slider 209, respectively. The inner side of the second extension rail 107 is slidably connected to both first sliders 206. Pins 207 are inserted into the inner side of the positioning holes 108. Figures 1-2 As shown, the crusher 1 can be a double-roll crusher in the prior art. The first extension rail 106 and the second extension rail 107 can be welded or fixed to both sides of the crusher housing by bolts.

[0023] The working principle of this utility model: When the device is in use, a large plastic sheet can be inserted from top to bottom between two uprights 201. Each support roller 202 clamps the plastic sheet. Then, the servo motor 102 is started, which drives the crushing blade assembly 103 to rotate towards the center of the crushing box 101. The crushing blade assembly 103 can then crush the lower end of the plastic sheet. The crushed plastic pieces are discharged through the discharge hopper 104. The operator only needs to push the plastic sheet downward to ensure that the crushing blade assembly 103 continues to contact and crush the lower end of the plastic sheet.

[0024] Secondly, when it is necessary to adjust the distance between the two uprights 201, first loosen the two lowering nuts 213. The support plate 211 falls under the action of gravity, and the groove 212 separates from the end of the telescopic plate 214. At this time, the second slider 208 and the third slider 209 can slide in different directions along the first extension rail 106, thereby adjusting the distance between the two uprights 201. Then loosen the lowering nut 217. The second nut 217 separates from the telescopic plate 214, and the telescopic plate 214 can slide horizontally along the third slider 209. The end of the telescopic plate 214 can move to the support plate 211. Above, when the first nut 213 is tightened again and lifted along the threaded shaft 210, the first nut 213 pushes the support plate 211 upward, and the groove 212 hooks the end of the telescopic plate 214. Finally, the second nut 217 is tightened, and the telescopic plate 214 and the third slider 209 are fixed relative to each other, and the position between the two uprights 201 is fixed. Then, the two uprights 201 are pushed, so that the first slider 206 moves along the second extension rail 107 until the gap between the uprights 201 is aligned with the middle of the crushing box 101. Then, the pin 207 is passed through the first slider 206 and inserted into the positioning hole 108 to complete the fixation.
