Description

Technical Field

[0001] The invention belongs to the technical field of plastic recycling, in particular to a degradable plastic recycling crusher. Background Art

[0002] Degradable plastic refers to a type of plastic that can degrade into environmentally friendly substances under natural conditions after use. In the process of recycling waste plastics, the plastic usually needs to be crushed. The crushed plastic particles are more convenient for subsequent use. At the same time, the volume of the crushed plastic is reduced, which not only reduces transportation costs but also saves storage space.

[0003] Patent No. CN218314631U discloses a crushing device for degradable plastics, comprising a material box, the bottom surface of which is fixedly connected to a transfer box, the inner top wall of which is fixedly connected to an electric push rod, the inner top wall of which is fixedly connected to a card plate, the inner slidable connection of the card plate to a baffle, the left side of the baffle being fixedly connected to the output end of the electric push rod, and the bottom surface of the transfer box being fixedly connected to a bottom plate. This crushing device for degradable plastics, through the cooperation of a drive motor and two gears in the frame, causes the roller in the material box to rotate and evenly crush the degradable plastics. Through the cooperation of the electric push rod, the card plate and the baffle, the crushed plastics can indirectly fall into the transfer box through the leakage at the bottom of the material box. Through the cooperation of the stepping motor and the conveying device in the transfer box, the plastics are conveyed out by a conveyor belt, which facilitates the operation of the staff and solves the problem that the crushed plastics are difficult to collect.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] When the biodegradable plastic is crushed in the material box, the fragments will fall into the conveyor box through the leakage at the bottom of the material box and be transferred out by the conveyor belt. Although this method is convenient for the staff to operate, since the specifications of the leakage at the bottom of the material box are fixed, the distribution range of the fragments when discharged from the leakage is also fixed. In some cases, a cylindrical collection bucket is used to collect the fragments. When the opening of the collection bucket is smaller than the leakage at the bottom of the material box, the fragments will fall to the outside of the collection bucket, affecting the normal collection work. In order to avoid this situation, the leakage is set too small, which will cause the fragments to fall slowly. When multiple collection buckets are needed to collect the fragments, if the material receiving speed is slow, it will affect the collection of the fragments by subsequent collection buckets, thereby reducing the overall collection efficiency.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The biodegradable plastic recycling crusher described in the present invention utilizes a radial material control mechanism and an expansion-type downward pressure mechanism. The crushed plastic will first fall into a funnel composed of an arc-shaped shell and a filling cloth. Under the limitation of the arc-shaped shell and the filling cloth, the crushed plastic will be concentrated and accurately fall into the collection bucket, thereby avoiding the situation where the crushed plastic falls outside the collection bucket due to the discharge range of the crushed plastic being larger than the opening of the collection bucket, thereby ensuring the normal collection of the crushed plastic. At the same time, the speed at which the collection bucket collects the crushed plastic depends on the size of its own opening. The collection speed of the scraps is greatly improved, and the collection efficiency of the scraps by multiple collection buckets is improved. When the collection bucket completes the scrap collection work, the edge of the filling cloth can be made to fit with the inner wall of the collection bucket under the action of the pressure plate and the filling cloth. Then the pressure plate and the filling cloth are driven into the collection bucket, and the pressure plate and the filling cloth can be used to squeeze the scraps in the collection bucket to compress the volume of the scraps. Moreover, since the edge of the stretched filling cloth fits with the inner wall of the collection bucket, the pressure plate and the filling cloth only need to be lowered once. The crushed materials in all directions can be squeezed out, which reduces the dead angle of squeezing and improves the squeezing efficiency. When the volume of the crushed materials is compressed, the collecting bucket is moved away to avoid the crushed materials in the collecting bucket being higher than the upper edge of the collecting bucket and the crushed materials falling out through the edge of the collecting bucket after the arc shell is away from the collecting bucket. Similarly, when the crushed materials fall into the collecting bucket, the pressure plate and the filling cloth 2 can be used to compress the crushed materials in the collecting bucket in real time to increase the storage space of the collecting bucket. In addition, multiple telescopic rods and sleeves can be lowered at the same time to adjust the filling cloth 2. The squeezing process makes the filling cloth 2 tight. When the filling cloth 2 contacts the scraps, the action of the telescopic rod and the sleeve can effectively reduce the depression of the filling cloth 2 caused by squeezing the scraps, further improving the compaction effect of the scraps. Moreover, after the squeezing work is completed, the sleeve and the telescopic rod can be driven to repeatedly squeeze the filling cloth 2 to promote the falling of the scraps adhering to its lower surface, thereby avoiding the situation where the filling cloth 2 carries scraps in the depression, and the scraps carried by the filling cloth 2 are mixed with the rest of the scraps when the filling cloth 2 is used later, thereby affecting the purity of the scraps.

[0023] 2. In the biodegradable plastic recycling crusher described in the present invention, the crushed debris will first fall onto the baffle, and the moisture therein will also slide through the baffle to the filter screen, flow into the water collecting box, and be discharged from the water outlet. After the moisture is separated from the debris, the motor six is ​​used to drive the threaded rod one to rotate, so that the debris continues to fall downward, thereby avoiding the situation where the crushed debris carries moisture, the debris floats in the collection bucket, and affects the squeezing effect of the pressure plate and the filling cloth two on the debris.

[0048] Specifically, in the prior art, after the biodegradable plastic is crushed in the material box, the crushed materials will fall into the conveyor box through the leakage hole at the bottom of the material box and be conveyed out by the conveyor belt. Although this method is convenient for the staff to operate, since the specifications of the leakage hole at the bottom of the material box are fixed, the distribution range of the crushed materials when discharged from the leakage hole is also fixed. In some cases, a cylindrical collection bucket is used to collect the crushed materials. When the opening of the collection bucket is smaller than the leakage hole at the bottom of the material box, the crushed materials will fall outside the collection bucket, affecting the normal collection work. In order to avoid this situation, the leakage hole is set too small, which will cause the crushed materials to fall slowly. When multiple collection buckets are needed to collect the crushed materials, if the material receiving speed is slow, it will affect the collection of the crushed materials by the subsequent collection buckets, thereby reducing the overall collection efficiency.

[0049] Therefore, in order to solve the above problems, when the present embodiment is in use, the cylindrical collecting buckets for collecting the crushed materials are placed one by one on the conveyor belt 4, and as the conveyor belt 4 runs, the collecting buckets are moved to the bottom of the crushing box 5, and according to the distance between the bottom of the arc shell 17 and the opening of the collecting bucket, the motor 4 36 drives the threaded rod 5 37 to rotate, so that the crushing box 5 moves downward until the bottom of the arc shell 17 extends into the inner cavity of the collecting bucket, and then the motor 5 39 drives the threaded rod 2 15 to rotate, so that the adjusting ring 13 moves longitudinally, and the multiple connecting rods 14 rotate at the same time, so that the multiple radial rods 16 move radially at the same time, and the filling cloth 18 is also stretched, so that the arc shell 17 contacts the inner wall of the collecting bucket, and the collecting bucket can be fixed by supporting the inner cavity wall of the collecting bucket by the multiple arc shells 17 at the same time, and then the motor 17 drives the crushing roller 6 on one side to rotate, under the action of the gear 35 The crushing rollers 6 on both sides rotate in different directions at the same time, and the plastic to be crushed is added to the crushing box 5. The two crushing rollers 6 are used to crush the plastic. The crushed plastic will first fall into the funnel composed of the arc shell 17 and the filling cloth 18, and under the limitation of the arc shell 17 and the filling cloth 18, the crushed plastic can be concentrated and accurately fall into the collection bucket, thereby avoiding the situation where the crushed plastic falls outside the collection bucket due to the discharge range of the crushed plastic being larger than the opening of the collection bucket, ensuring the normal collection of the crushed plastic. At the same time, the speed of the collection bucket for crushing the plastic depends on the size of its own opening, which maximizes the speed of collecting the plastic and improves the collection efficiency of multiple collection buckets for crushing the plastic. When a collection bucket completes the collection work, the arc shell 17 moves away from the inner wall of the collection bucket, loosens the collection bucket, and the collection bucket moves with the conveyor belt 4. The staff can remove the collection bucket containing the crushed plastic.

[0050] Although the above method ensures that the collection bucket can collect the debris smoothly, when the debris is inside the collection bucket, the debris may accumulate too high in the inner cavity of the collection bucket. This may be caused by too much debris or local accumulation of debris in the collection bucket. When the height of the debris accumulation exceeds the upper edge of the collection bucket, the arc shell 17 is away from the collection bucket, and the debris may fall out through the edge of the collection bucket, causing trouble. Therefore, in order to avoid this situation, after the collection bucket completes the debris collection work, according to the size of the collection bucket opening, the motor 21 is used to drive the threaded rod 3 25 to rotate, so that the threaded block 22 moves longitudinally, and the multiple connecting rods 2 43 are rotated at the same time, so that the multiple adjustment plates 28 can slide radially on the pressure plate 24 at the same time, and the multiple pressure blocks 27 are used to drive the edge of the filling cloth 26 to move, so that the filling cloth 26 is stretched, and under the action of the pressure plate 24 and the filling cloth 26, the edge of the filling cloth 26 is fit to the inner cavity wall of the collection bucket, and then the motor 7 41 drives the threaded rod 4 34 to rotate. In this way, the lifting rod 20 is lowered, and the pressure plate 24 and the second filling cloth 26 are extended into the collection bucket. The pressure plate 24 and the second filling cloth 26 can be used to squeeze the scraps in the collection bucket to compress the volume of the scraps. Moreover, since the edge of the stretched second filling cloth 26 fits the inner wall of the collection bucket, the pressure plate 24 and the second filling cloth 26 only need to be lowered once to squeeze the scraps in all directions, thereby reducing the extrusion dead angle and improving the extrusion efficiency. When the volume of the scraps is compressed, the collection bucket is moved away. This prevents the debris in the collection bucket from falling out of the edge of the collection bucket after the curved shell 17 is away from the collection bucket due to the debris in the collection bucket being higher than the upper edge of the collection bucket. In addition, since the shell 42 is conical, when the debris falls into the curved shell 17, it will slide down the inclined surface of the shell 42, and the debris will not accumulate on the shell 42. Similarly, when the debris falls into the collection bucket, the pressure plate 24 and the filling cloth 26 can be used to compress the debris in the collection bucket in real time, thereby increasing the storage space of the collection bucket.

[0051] Although the filling cloth 26 can be used to squeeze the debris in the collection barrel to reduce the volume of the debris, due to the elasticity of the filling cloth 26, when the filling cloth 26 contacts the debris, the filling cloth 26 will be depressed by the squeezing of the debris, resulting in some debris not being compacted. Moreover, when the debris is sticky, the plastic may adhere to the depression of the filling cloth 26, causing the filling cloth 26 to carry the debris. When the filling cloth 26 is used later, these carried debris may be mixed with the rest of the debris, thereby affecting the purity of the debris. Therefore, in order to avoid this situation, when the adjustment 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 the two adjacent adjustment plates 28. Then, the motor 3 29 is used to drive the threaded rod 6 44 to rotate, so that the connecting rod 32 on one side descends, and with the cooperation of multiple connecting rods 32, the sleeve 30, and the telescopic rod 31, The multiple telescopic rods 31 and sleeves 30 are lowered at the same time to squeeze the filling cloth 26, so that the filling cloth 26 is tightened. When the filling cloth 26 contacts the scraps, the action of the telescopic rods 31 and sleeves 30 can effectively reduce the depression of the filling cloth 26 due to squeezing the scraps, further improving the compaction effect of the scraps. Moreover, after the squeezing work is completed, the motor 3 29 can drive the threaded rod 6 44 to rotate forward and reversely, so that the sleeve 30 and the telescopic rods 31 repeatedly squeeze the filling cloth 26, promote the falling of the scraps adhering to its lower surface, and avoid the scraps carried by the depression of the filling cloth 26. When the filling cloth 26 is used later, these carried scraps are mixed with the rest of the scraps, thereby affecting the purity of the scraps.

[0052] In this embodiment, Figure 3 and Figure 8 As shown, a baffle 19 is inserted and slidably connected to one side of the crushing box 5, a filter screen 9 is provided on one side of the crushing box 5, and 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 provided at one end of the water collecting box 10.

[0053] One side of the baffle 19 is threadedly connected to a threaded rod 8, one end of the threaded rod 8 is rotatably set on the crushing box 5, and one side of the crushing box 5 is fixedly connected to a motor 6 40, and the output end of the motor 6 40 is fixedly connected to one end of the threaded rod 8.

[0054] Specifically, in the above embodiment, although the crushed materials in the collection barrel can be squeezed, when the plastic contains moisture, the crushed materials will carry the moisture into the collection barrel, causing the crushed materials in the collection barrel to float, thereby affecting the squeezing of the crushed materials by the pressure plate 24 and the filling cloth 26. Therefore, in order to avoid this situation, the crushed materials will first fall onto the baffle 19, and the moisture therein will also slide through 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 crushed materials, the motor 6 40 is used to drive the threaded rod 18 to rotate, so that the crushed materials continue to fall downward, thereby avoiding the situation where the crushed materials carry moisture and the crushed materials float in the collection barrel, affecting the squeezing effect of the pressure plate 24 and the filling cloth 26 on the crushed materials.

[0055] Working principle: The cylindrical collecting buckets for collecting crushed materials are placed one by one on the conveyor belt 4. As the conveyor belt 4 runs, the collecting buckets are moved to the bottom of the crushing box 5. According to the distance between the bottom of the arc shell 17 and the opening of the collecting bucket, the motor 4 36 drives the threaded rod 5 37 to rotate, so that the crushing box 5 moves downward until the bottom of the arc shell 17 extends into the inner cavity of the collecting bucket. Then, the motor 5 39 drives the threaded rod 2 15 to rotate, so that the adjusting ring 13 moves longitudinally, and the multiple connecting rods 14 rotate at the same time, so that the multiple radial rods 16 can move radially at the same time, and the filling cloth 18 will also be stretched, so that the arc shell 17 contacts the inner wall of the collecting bucket. The collecting bucket can be fixed by supporting the inner wall of the collecting bucket by multiple arc shells 17 at the same time. Then, the motor 17 drives the crushing roller 6 on one side to rotate, and the crushing rollers on both sides are driven by the gear 35. 6 rotates in different directions at the same time, and adds the plastic to be crushed into the crushing box 5, and uses two crushing rollers 6 to crush the plastic. The crushed plastic will first fall into the funnel composed of the arc shell 17 and the filling cloth 18, and under the limitation of the arc shell 17 and the filling cloth 18, the crushed plastic can be concentrated and accurately fall into the collection bucket, thereby avoiding the situation where the crushed plastic falls outside the collection bucket due to the discharge range of the crushed plastic being larger than the opening of the collection bucket, ensuring the normal collection of the crushed plastic. At the same time, the speed of the collection bucket for crushing depends on the size of its own opening, which maximizes the collection speed of the crushed plastic and improves the collection efficiency of multiple collection buckets for crushed plastic. When a collection bucket completes the collection work, the arc shell 17 moves away from the inner wall of the collection bucket, loosens the collection bucket, and the collection bucket moves with the conveyor belt 4 again. The staff can remove the collection bucket containing the crushed plastic.Although the above method ensures that the collection bucket can collect the debris smoothly, when the debris is inside the collection bucket, the debris may accumulate too high in the inner cavity of the collection bucket. This may be caused by too much debris or local accumulation of debris in the collection bucket. When the height of the debris accumulation exceeds the upper edge of the collection bucket, the arc shell 17 is away from the collection bucket, and the debris may fall out through the edge of the collection bucket, causing trouble. Therefore, in order to avoid this situation, after the collection bucket completes the debris collection work, according to the size of the collection bucket opening, the motor 21 is used to drive the threaded rod 3 25 to rotate, so that the threaded block 22 moves longitudinally, and the multiple connecting rods 2 43 are rotated at the same time, so that the multiple adjustment plates 28 can slide radially on the pressure plate 24 at the same time, and the multiple pressure blocks 27 are used to drive the edge of the filling cloth 26 to move, so that the filling cloth 26 is stretched, and under the action of the pressure plate 24 and the filling cloth 26, the edge of the filling cloth 26 is fit to the inner cavity wall of the collection bucket, and then the motor 7 41 drives the threaded rod 4 34 to rotate. In this way, the lifting rod 20 is lowered, and the pressure plate 24 and the second filling cloth 26 are extended into the collection bucket. The pressure plate 24 and the second filling cloth 26 can be used to squeeze the scraps in the collection bucket to compress the volume of the scraps. Moreover, since the edge of the stretched second filling cloth 26 fits the inner wall of the collection bucket, the pressure plate 24 and the second filling cloth 26 only need to be lowered once to squeeze the scraps in all directions, thereby reducing the extrusion dead angle and improving the extrusion efficiency. When the volume of the scraps is compressed, the collection bucket is moved away. This prevents the debris in the collection bucket from falling out of the edge of the collection bucket after the curved shell 17 is away from the collection bucket due to the debris in the collection bucket being higher than the upper edge of the collection bucket. In addition, since the shell 42 is conical, when the debris falls into the curved shell 17, it will slide down the inclined surface of the shell 42, and the debris will not accumulate on the shell 42. Similarly, when the debris falls into the collection bucket, the pressure plate 24 and the filling cloth 26 can be used to compress the debris in the collection bucket in real time, thereby increasing the storage space of the collection bucket.Although the filling cloth 26 can be used to squeeze the debris in the collection bucket to reduce the volume of the debris, the filling cloth 26 is elastic. Therefore, when the filling cloth 26 contacts the debris, the filling cloth 26 will be depressed by the squeezing of the debris, resulting in some debris not being compacted. Moreover, when the debris is sticky, the plastic may adhere to the depression of the filling cloth 26, causing the filling cloth 26 to carry the debris. When the filling cloth 26 is used later, these carried debris may be mixed with the rest of the debris, thereby affecting the purity of the debris. Therefore, in order to avoid this situation, when the adjustment 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 the two adjacent adjustment plates 28. Then, the motor 3 29 is used to drive the threaded rod 6 44 to rotate, so that the connecting rod 32 on one side descends, and with the cooperation of multiple connecting rods 32, the sleeve 30, and the telescopic rod 31, The multiple telescopic rods 31 and sleeves 30 are lowered at the same time to squeeze the filling cloth 26, so that the filling cloth 26 is tightened. When the filling cloth 26 contacts the scraps, the action of the telescopic rods 31 and sleeves 30 can effectively reduce the depression of the filling cloth 26 due to squeezing the scraps, further improving the compaction effect of the scraps. Moreover, after the squeezing work is completed, the motor 3 29 can drive the threaded rod 6 44 in a forward and reverse manner, so that the sleeve 30 and the telescopic rod 31 repeatedly squeeze the filling cloth 26, promote the falling of the scraps adhering to the lower surface, and avoid the depression of the filling cloth 26. The entrained debris and filling cloth 26 may mix with the remaining debris during subsequent use, affecting the purity of the debris. The crushed debris will first fall onto baffle 19, where the water in it will also slide through baffle 19 to filter screen 9, flow into water collection box 10, and be discharged through outlet 11. After the water is separated from the debris, motor 6 40 drives threaded rod 1 8 to rotate, allowing the debris to continue falling downward. This prevents the crushed debris from carrying water, causing the debris to float in the collection bucket and affect the crushing effect of pressure plate 24 and filling cloth 2 26 on the debris.
