Description

Technical Field

[0001] The present invention belongs to the technical field of plastic recycling, and specifically relates to a degradable plastic recycling crusher. Background Art

[0002] Degradable plastics refer to plastics that can degrade into environmentally harmless substances under natural environmental conditions after use. During the recycling process of waste plastics, it is usually necessary to crush the plastics. The crushed plastic particles are more convenient for subsequent utilization. At the same time, the volume of the crushed plastics is reduced, which not only reduces the transportation cost but also saves storage space.

[0003] The patent with the publication number CN218314631U discloses a crushing device for degradable plastics, including a material box. The bottom surface of the material box is fixedly connected with a transmission box. The inner top wall of the transmission box is fixedly connected with an electric push rod. The inner top wall of the transmission box is fixedly connected with a clamping plate. A baffle is slidably connected inside the clamping plate. The left side surface of the baffle is fixedly connected with the output end of the electric push rod. The bottom surface of the transmission box is fixedly connected with a bottom plate. In this crushing device for degradable plastics, through the cooperation of the driving motor and two gears in the frame, the hob in the material box rotates to evenly crush the degradable plastics. Through the cooperation of the electric push rod, the clamping plate and the baffle, the crushed plastics can indirectly fall into the transmission box through the leakage opening at the bottom of the material box. Through the cooperation of the stepping motor and the transmission device in the transmission box, it is transmitted by the conveyor belt, which facilitates the operation of the staff and solves the problem that the crushed plastics are not easy to collect.

[0004] However, the above technical solution still has the following deficiencies in actual application: When the degradable plastics are crushed in the material box, the shredded materials will fall into the transmission box through the leakage opening at the bottom of the material box and be transmitted by the conveyor belt. Although this method facilitates the operation of the staff, since the specification of the leakage opening at the bottom of the material box is fixed, the distribution range of the shredded materials when discharged from the leakage opening is also fixed. In some cases, a cylindrical collection bucket is used to collect the shredded materials. When the opening of the collection bucket is smaller than the leakage opening at the bottom of the material box, it will cause the shredded materials to fall outside the collection bucket, affecting the normal progress of the collection work. And when the leakage opening is set too small to avoid this situation, it will cause the shredded materials to fall slowly. When multiple collection buckets are needed to collect the shredded materials, if the material receiving speed is slow, it will affect the collection of the shredded materials by the subsequent collection buckets, thereby reducing the overall collection efficiency.

[0016] The beneficial effects of the present invention are as follows: 1. A degradable plastic recycling crusher according to the present invention utilizes a radial material control mechanism and an expandable downward pressing mechanism. After crushing, the plastic will first fall into the funnel formed by the arc-shaped shell and the filling cloth 1. Under the limitation of the arc-shaped shell and the filling cloth 1, the crushed materials can be concentrated and accurately fall into the collection bucket, thus avoiding the situation that the crushed materials fall outside the collection bucket due to the discharge range of the crushed materials being larger than the opening of the collection bucket, ensuring the normal collection of the crushed materials. At the same time, the speed at which the collection bucket collects the crushed materials depends on the size of its own opening, maximizing the collection speed of the crushed materials and improving the collection efficiency of multiple collection buckets for the crushed materials. When the collection bucket completes the collection work of the crushed materials, under the action of the pressing plate and the filling cloth 2, the edge of the filling cloth 2 can be made to fit the inner cavity wall of the collection bucket, and then the pressing plate and the filling cloth 2 are driven to extend into the collection bucket, and the crushed materials in the collection bucket can be squeezed by the pressing plate and the filling cloth 2, so that the volume of the crushed materials can be compressed. Moreover, since the edge of the stretched filling cloth 2 fits the inner wall of the collection bucket, the pressing plate and the filling cloth 2 only need to descend once to squeeze the crushed materials in all directions, reducing the squeezing dead angle and improving the squeezing efficiency. When the volume of the crushed materials is compressed, then the collection bucket is moved away, which can avoid the situation that the crushed materials in the collection bucket are higher than the upper edge of the collection bucket, and when the arc-shaped shell moves away from the collection bucket, the crushed materials fall out through the edge of the collection bucket. Similarly, when the crushed materials fall into the collection bucket, the pressing plate and the filling cloth 2 can also be used to compress the crushed materials in the collection bucket in real time to improve the storage space of the collection bucket. And multiple telescopic rods and sleeves can be simultaneously lowered to squeeze the filling cloth 2, making the filling cloth 2 taut. When the filling cloth 2 contacts the crushed materials, under the action of the telescopic rods and the sleeves, the depression of the filling cloth 2 caused by squeezing the crushed materials can be effectively reduced, further improving the compaction effect on the crushed materials. And after the squeezing work is completed, the sleeves and the telescopic rods can be driven to repeatedly squeeze the filling cloth 2 to promote the falling of the crushed materials adhering to its lower surface, avoiding the situation that the crushed materials carried by the depression of the filling cloth 2 are mixed with the remaining crushed materials when the filling cloth 2 is used subsequently, thus affecting the purity of the crushed materials.

[0017] 2. A degradable plastic recycling crusher according to the present invention, the crushed materials after crushing will first fall onto the baffle, and the moisture therein will also slide down the baffle to the filter screen and flow into the water collection box and be discharged from the water outlet. After the moisture is separated from the crushed materials, then the motor six is used to drive the screw rod one to rotate, and the crushed materials can continue to fall downward, thus avoiding the situation that the crushed materials carry moisture after crushing and float in the collection bucket, affecting the squeezing effect of the pressing plate and the filling cloth 2 on the crushed materials.

[0030] Specifically, in the prior art, when the degradable plastic is crushed in the material box, the crushed material will fall into the transfer box through the leak hole at the bottom of the material box and be conveyed out by the conveyor belt. Although this method facilitates the operation of the staff, however, since the specification of the leak hole at the bottom of the material box is fixed, the distribution range of the crushed material when it is discharged from the leak hole is also fixed. In some cases, a cylindrical collection bucket is used to collect the crushed material. When the opening of the collection bucket is smaller than the leak hole at the bottom of the material box, it will cause the crushed material to fall outside the collection bucket, affecting the normal progress of the collection work. And when the leak hole is set too small to avoid this situation, it will cause the crushed material to fall slowly. When multiple collection buckets are needed to collect the crushed material, if the material receiving speed is slow, it will affect the collection of the crushed material by the subsequent collection buckets, thereby reducing the overall collection efficiency. Therefore, to solve the above problems, during the use of this embodiment, the cylindrical collection barrels for collecting shredded materials are placed one by one on the conveyor belt 4. As the conveyor belt 4 operates, the collection barrels are moved to the lower part of the crushing box 5. According to the distance between the bottom of the arc-shaped shell 17 and the opening of the collection barrel, the motor four 36 drives the rotation of the threaded rod five 37, so that the crushing box 5 moves downward until the bottom of the arc-shaped shell 17 extends into the inner cavity of the collection barrel. Then, the motor five 39 drives the rotation of the threaded rod two 15, so that the adjusting ring 13 moves longitudinally, and multiple connecting rods one 14 rotate simultaneously, so that multiple radial rods 16 can move radially at the same time, and the filling cloth one 18 will also be stretched, making the arc-shaped shell 17 contact the inner wall of the collection barrel. In this way, the collection barrel can be fixed by the multiple arc-shaped shells 17 supporting the inner wall of the collection barrel at the same time. Then, the motor one 7 drives the rotation of the crushing roller 6 on one side. Under the action of the gear 35, the two crushing rollers 6 rotate in different directions at the same time, and the plastic to be crushed is added into the crushing box 5. The two crushing rollers 6 are used to crush the plastic. The crushed plastic will first fall into the funnel formed by the arc-shaped shell 17 and the filling cloth one 18. Under the limitation of the arc-shaped shell 17 and the filling cloth one 18, the shredded materials can be concentrated and accurately fall into the collection barrel, thus avoiding the situation that the shredded materials fall outside the collection barrel due to the discharge range of the shredded materials being larger than the opening of the collection barrel, ensuring the normal collection of the shredded materials. At the same time, the speed of the collection barrel for the shredded materials depends on the size of its own opening, which maximally improves the collection speed of the shredded materials and improves the collection efficiency of multiple collection barrels for the shredded materials; when a collection barrel completes the collection work, the arc-shaped shell 17 moves away from the inner wall of the collection barrel, releases the collection barrel, and the collection barrel moves with the conveyor belt 4 again. The staff can then remove the collection barrel filled with shredded materials; Although the above method ensures the smooth collection of shredded materials by the collection bucket, when the shredded materials are inside the collection bucket, there may be a phenomenon that the shredded materials accumulate too high inside the inner cavity of the collection bucket. This may be caused by too much shredded materials or local accumulation of shredded materials in the collection bucket. When the height of the shredded material accumulation exceeds the upper edge of the collection bucket, the arc-shaped shell 17 moves away from the collection bucket, and it is possible that the shredded materials fall out through the edge of the collection bucket, causing trouble. Therefore, to avoid this situation, after the collection bucket completes the collection of shredded materials, according to the size of the opening of the collection bucket, the second motor 21 drives the third threaded rod 25 to rotate, so that the threaded block 22 moves longitudinally, and multiple second connecting rods 43 rotate simultaneously, so that multiple adjusting plates 28 can slide radially on the pressure plate 24 at the same time. By driving the edges of the second filling cloth 26 with multiple pressing blocks 27, the second filling cloth 26 is stretched. Then, under the action of the pressure plate 24 and the second filling cloth 26, the edge of the second filling cloth 26 is attached to the inner cavity wall of the collection bucket. Then, by driving the fourth threaded rod 34 to rotate with the seventh motor 41, the lifting rod 20 descends, and the pressure plate 24 and the second filling cloth 26 extend into the collection bucket, so that the shredded materials in the collection bucket can be squeezed by the pressure plate 24 and the second filling cloth 26, and the volume of the shredded materials can be compressed. Moreover, since the edge of the stretched second filling cloth 26 is attached to the inner wall of the collection bucket, the pressure plate 24 and the second filling cloth 26 only need to descend once to squeeze the shredded materials in all directions, reducing the squeezing dead angle and improving the squeezing efficiency. After the volume of the shredded materials is compressed, the collection bucket is moved away, which can avoid the situation that the shredded materials in the collection bucket are higher than the upper edge of the collection bucket and the arc-shaped shell 17 moves away from the collection bucket, and the shredded materials fall out through the edge of the collection bucket. Moreover, since the housing 42 is conical, when the shredded materials fall into the arc-shaped shell 17, they will slide down along the inclined surface of the housing 42, and there will be no situation where the shredded materials accumulate on the housing 42. Similarly, when the shredded materials fall into the collection bucket, the pressure plate 24 and the second filling cloth 26 can also be used to compress the shredded materials in the collection bucket in real time to increase the storage space of the collection bucket; Although the filler cloth II 26 can be used to extrude the scraps in the collection cylinder to compress the volume of the scraps, however, due to the elasticity of the filler cloth II 26, when the filler cloth II 26 contacts the scraps, the filler cloth II 26 will be indented due to the extrusion of the scraps, resulting in some scraps not being compacted. Moreover, when the scraps are sticky, the plastic may adhere to the indentation of the filler cloth II 26, resulting in the filler cloth II 26 carrying the scraps. When the filler cloth II 26 is used subsequently, these carried scraps may be mixed with the remaining scraps, thus affecting the purity of the scraps. Therefore, to avoid this situation, when the adjusting plate 28 moves, the sleeve 30 and the telescopic rod 31 slide relative to each other, and the degree of relative sliding between the sleeve 30 and the telescopic rod 31 depends on the distance between two adjacent adjusting plates 28. Then, the motor III 29 drives the threaded rod VI 44 to rotate, causing the connecting rod 32 on one side to descend. With the cooperation of multiple connecting rods 32, sleeves 30, and telescopic rods 31, multiple telescopic rods 31 can descend simultaneously with the sleeves 30 to extrude the filler cloth II 26, making the filler cloth II 26 taut. When the filler cloth II 26 contacts the scraps, under the action of the telescopic rod 31 and the sleeve 30, the indentation of the filler cloth II 26 caused by extruding the scraps can be effectively reduced, further improving the compaction effect on the scraps. Moreover, after the extrusion work is completed, the sleeve 30 and the telescopic rod 31 can be used to repeatedly extrude the filler cloth II 26 by driving the threaded rod VI 44 to rotate forward and backward by the motor III 29, promoting the falling of the scraps adhering to its lower surface, avoiding the situation that the filler cloth II 26 carries scraps at the indentation and these carried scraps are mixed with the remaining scraps when the filler cloth II 26 is used subsequently, thus affecting the purity of the scraps.

[0031] In this embodiment, as Figure 3 and Figure 8 shown, a baffle 19 is inserted and slidably connected to one side of the crushing box 5. A filter screen 9 is arranged on one side of the crushing box 5. A water collecting box 10 is fixedly connected to one side of the left end face of the crushing box 5, and a water outlet 11 is arranged at one end of the water collecting box 10.

[0032] One side of the baffle 19 is threadedly connected with a threaded rod I 8. One end of the threaded rod I 8 is rotatably arranged on the crushing box 5. A motor VI 40 is fixedly connected to one side of the crushing box 5, and the output end of the motor VI 40 is fixedly connected to one end of the threaded rod I 8.

[0033] Specifically, in the above embodiments, although the shredded materials in the collection bucket can be extruded, when the plastic contains moisture, the shredded materials after crushing will carry this moisture into the collection bucket, resulting in the phenomenon that the shredded materials in the collection bucket float up, which in turn affects the extrusion of the shredded materials by the pressing plate 24 and the second filling cloth 26. Therefore, to avoid this situation, the shredded materials after crushing will first fall onto the baffle 19, and the moisture therein will also slide down the baffle 19 to the filter screen 9 and flow into the water collection box 10 and be discharged from the water outlet 11. After the moisture is separated from the shredded materials, the motor six 40 is used to drive the first threaded rod 8 to rotate, so that the shredded materials can continue to fall downward, thus avoiding the situation where the shredded materials carry moisture after crushing, causing the shredded materials to float in the collection bucket and affecting the extrusion effect of the pressing plate 24 and the second filling cloth 26 on the shredded materials.

[0034] Working principle: The cylindrical collection barrels for collecting shredded materials are placed on the conveyor belt 4 one by one. As the conveyor belt 4 operates, the collection barrels are moved to the lower part of the crushing box 5. According to the distance between the bottom of the arc-shaped shell 17 and the opening of the collection barrel, the motor four 36 drives the rotation of the threaded rod five 37, so that the crushing box 5 moves downward until the bottom of the arc-shaped shell 17 extends into the inner cavity of the collection barrel. Then, the motor five 39 drives the rotation of the threaded rod two 15, causing the adjusting ring 13 to move longitudinally, and multiple connecting rods one 14 to rotate simultaneously, so that multiple radial rods 16 can move radially at the same time. The filling cloth one 18 will also be stretched, making the arc-shaped shell 17 contact the inner wall of the collection barrel. In this way, the collection barrel can be fixed by simultaneously supporting the inner wall of the collection barrel by multiple arc-shaped shells 17. Then, the motor one 7 drives the rotation of the crushing roller 6 on one side. Under the action of the gear 35, the crushing rollers 6 on both sides rotate simultaneously in different directions, and the plastic to be crushed is added into the crushing box 5. The two crushing rollers 6 are used to crush the plastic. The crushed plastic will first fall into the funnel formed by the arc-shaped shell 17 and the filling cloth one 18. Under the limitation of the arc-shaped shell 17 and the filling cloth one 18, the shredded materials can be concentrated and accurately fall into the collection barrel, thus avoiding the situation where the shredded materials fall outside the collection barrel due to the discharge range of the shredded materials being larger than the opening of the collection barrel, ensuring the normal collection of the shredded materials. At the same time, the speed of the collection barrel for the shredded materials depends on the size of its own opening, maximizing the collection speed of the shredded materials and improving the collection efficiency of multiple collection barrels for the shredded materials; when a collection barrel completes the collection work, the arc-shaped shell 17 moves away from the inner wall of the collection barrel, releasing the collection barrel. The collection barrel then moves with the conveyor belt 4, and the staff can remove the collection barrel filled with shredded materials;Although the above method ensures the smooth collection of shredded materials by the collection bucket, when the shredded materials are inside the collection bucket, there may be a phenomenon that the shredded materials accumulate too high inside the inner cavity of the collection bucket. This may be caused by too much shredded materials or local accumulation of shredded materials in the collection bucket. When the height of the shredded material accumulation exceeds the upper edge of the collection bucket, the arc-shaped shell 17 moves away from the collection bucket, and it is possible that the shredded materials fall out through the edge of the collection bucket, causing trouble. Therefore, to avoid this situation, after the collection bucket completes the collection of shredded materials, according to the size of the opening of the collection bucket, the second motor 21 drives the third threaded rod 25 to rotate, so that the threaded block 22 moves longitudinally, and multiple second connecting rods 43 rotate simultaneously, then multiple adjusting plates 28 can slide radially on the pressure plate 24 at the same time. By driving the edges of the second filling cloth 26 with multiple pressing blocks 27, the second filling cloth 26 is stretched. Then, under the action of the pressure plate 24 and the second filling cloth 26, the edge of the second filling cloth 26 is attached to the inner wall of the collection bucket. Then, by driving the fourth threaded rod 34 to rotate by the seventh motor 41, the lifting rod 20 descends, and the pressure plate 24 and the second filling cloth 26 extend into the collection bucket. Thus, the shredded materials in the collection bucket can be extruded by the pressure plate 24 and the second filling cloth 26, so that the volume of the shredded materials is compressed. Moreover, since the edge of the stretched second filling cloth 26 is attached to the inner wall of the collection bucket, the pressure plate 24 and the second filling cloth 26 only need to descend once to extrude the shredded materials in all directions, reducing the extrusion dead angle and improving the extrusion efficiency. After the volume of the shredded materials is compressed, the collection bucket is moved away, which can avoid the situation that when the shredded materials in the collection bucket are higher than the upper edge of the collection bucket and the arc-shaped shell 17 moves away from the collection bucket, the shredded materials fall out through the edge of the collection bucket. Moreover, since the housing 42 is conical, when the shredded materials fall into the arc-shaped shell 17, they will slide down along the inclined surface of the housing 42, and there will be no situation where the shredded materials accumulate on the housing 42. Similarly, when the shredded materials fall into the collection bucket, the pressure plate 24 and the second filling cloth 26 can also compress the shredded materials in the collection bucket in real time to increase the storage space of the collection bucket;Although the filler cloth II 26 can be used to extrude the scraps in the collection bucket to compress the volume of the scraps, since the filler cloth II 26 is elastic, when the filler cloth II 26 contacts the scraps, the filler cloth II 26 will be indented due to the extrusion of the scraps, resulting in some scraps not being compacted. Moreover, when the scraps are sticky, the plastic may adhere to the indentation of the filler cloth II 26, causing the filler cloth II 26 to carry the scraps. When the filler cloth II 26 is used subsequently, these carried scraps may be mixed with the remaining scraps, affecting the purity of the scraps. Therefore, to avoid this situation, when the adjusting plate 28 moves, the sleeve 30 and the telescopic rod 31 slide relative to each other, and the degree of relative sliding between the sleeve 30 and the telescopic rod 31 depends on the distance between two adjacent adjusting plates 28. Then, the motor III 29 drives the threaded rod VI 44 to rotate, causing the connecting rod 32 on one side to descend. With the cooperation of multiple connecting rods 32, sleeves 30, and telescopic rods 31, multiple telescopic rods 31 can descend simultaneously with the sleeves 30 to extrude the filler cloth II 26, making the filler cloth II 26 tightened. When the filler cloth II 26 contacts the scraps, under the action of the telescopic rod 31 and the sleeve 30, the indentation of the filler cloth II 26 caused by extruding the scraps can be effectively reduced, further improving the compaction effect on the scraps. Moreover, after the extrusion work is completed, the sleeve 30 and the telescopic rod 31 can extrude the filler cloth II 26 repeatedly by driving the threaded rod VI 44 to rotate forward and backward by the motor III 29, promoting the falling of the scraps adhering to its lower surface, avoiding the situation that the filler cloth II 26 carries scraps at the indentation and these carried scraps are mixed with the remaining scraps when the filler cloth II 26 is used subsequently, affecting the purity of the scraps. The crushed scraps will first fall onto the baffle 19, and the moisture therein will also slide down the baffle 19 to the filter screen 9 and flow into the water collection box 10 and be discharged from the water outlet 11. After the moisture is separated from the scraps, the motor VI 40 drives the threaded rod I 8 to rotate, and the scraps can continue to fall downward, thus avoiding the situation that the crushed scraps carry moisture and float in the collection bucket, affecting the extrusion effect of the pressure plate 24 and the filler cloth II 26 on the scraps.
