[0004] When the pulverizing device is in use, the pulverized plastic particles cannot be screened and can only be pulverized once each time.

If re-pulverization is required, the plastic particles in the collection box can only be manually poured back into the feed funnel for pulverization, which is time-consuming and labor-intensive.

[0005] The utility model provides a plastic particle crushing device, which aims to solve the problem that the existing crushing device cannot screen the crushed plastic particles when in use, can only perform a single crushing each time, cannot automatically screen out larger plastic particles and crush them again, and if crushing is required again, the plastic particles in the collection box can only be manually poured into the feeding funnel again for crushing, which is time-consuming and laborious. At the same time, if there are many plastic particles in the collection box, the fine plastic particles cannot smoothly pass through the filter screen to be collected, and the limitation is large. At the same time, the crushed plastic particles cannot be transported to other places for collection, and the practicality is not high.

[0006] An embodiment of the utility model provides a plastic particle crushing device, including a collecting box, which is installed on a supporting frame. A feeding mechanism is arranged in the collecting box, a supporting column is fixedly connected to the inner wall of the collecting box, a crushing mechanism is arranged on the supporting column, a screening mechanism is arranged outside the crushing mechanism, and a vibrating mechanism is also arranged on the collecting box.

[0007] Furthermore, the feeding mechanism includes an accommodation box fixedly connected to the outer wall of one side of the collecting box, a first motor is fixedly connected to the accommodation box, an auger is rotatably connected to the collecting box, one end of the auger is fixedly connected to the output end of the first motor, and the other end of the auger is connected to the inner wall of the collecting box via a bearing.

[0008] By adopting the above technical solution, the rotation of the first motor drives the auger to rotate, and then the auger transports the crushed plastic particles to the outside through the discharge port at the bottom of the collection box and collects them, preventing the plastic particles from accumulating in the collection box.

[0009] Furthermore, the crushing mechanism includes a crushing box fixedly connected to the support column, the crushing box is in a concave shape, a fixing ring is fixedly connected to the outer wall of the crushing box, a feeding channel is connected below the crushing box, the upper end of the feeding channel is connected to the internal cavity of the crushing box, and the lower end of the feeding channel faces the opening of the collecting box, two crushing rollers are rotatably connected in the feeding channel, the two crushing rollers are meshed with each other, a second motor is fixedly connected to the outer wall of the feeding channel, and the output end of the second motor extends into the feeding channel and is fixedly connected to one of the crushing rollers.

[0010] By adopting the above technical solution, the plastic particles to be crushed are poured into the crushing box. Since the crushing box is directly connected to the feeding channel, the plastic particles will directly fall into the feeding channel. Driven by the second motor, the two meshing crushing rollers in the feeding channel will crush the plastic particles.

[0011] Furthermore, the screening mechanism includes a convex edge rotatably connected to the outer peripheral wall of the fixed ring, a ring gear is fixedly connected to the outer peripheral wall of the convex edge, a third motor is fixedly connected to one side of the crushing box, a cylindrical gear is fixedly connected to the output end of the third motor, the cylindrical gear is meshed with the ring gear, a screening ring is fixedly connected to the side wall surface of the convex edge away from the support column, the screening ring and the convex edge are integrally formed, a plurality of evenly distributed screening holes are provided on the outer surface of the screening ring, and a plurality of equally spaced partitions are fixedly connected to the inner peripheral wall of the screening ring.

[0012] By adopting the above technical solution, under the driving cooperation of the third motor, the ring gear and the cylindrical gear, the convex edge will rotate on the surface of the fixed circle, and then the screening circle will also rotate synchronously, and a number of bearing areas will be formed between the inner wall of the screening circle and the partition plate. The bearing areas will carry the crushed plastic particles from the feeding channel. At the same time, the screening holes will filter the plastic particles that have been crushed small enough. The larger plastic particles that are not completely crushed and remain in the bearing area will fall back into the crushing box under the action of gravity and be crushed again during the rotation of the screening circle until they can pass through the screening holes.

[0013] Furthermore, the vibration mechanism includes a vibration plate fixedly connected to the top opening of the collection box, and a plurality of elastic metal sheets are fixedly connected to the top of the vibration plate. The top ends of the elastic metal sheets extend into the screening holes, and the number of the elastic metal sheets matches the number of the screening holes.

[0014] By adopting the above technical solution, during the rotation of the screening circle, the elastic metal sheet on the vibration plate will enter the next row of screening holes from the original screening holes, thereby achieving percussion and vibration of the screening circle during the rotation process, thereby improving the pass rate of fine plastic particles and effectively avoiding the situation where fine plastic particles cannot pass through the screening holes due to the accumulation of larger plastic particles.

[0015] Furthermore, the fixing ring, the convex edge and the screening ring are all circular, and the partitions are all arranged toward the center of the circle.

[0016] By adopting the above technical solution, the plastic particles that fall into the bearing area formed by the partition and the screening ring can smoothly fall back into the crushing box, avoiding falling to the outside.

[0017] Furthermore, a discharge port is provided at the bottom of the collecting box away from the first motor.

[0018] By adopting the above technical solution, the crushed plastic particles transported by the auger can be discharged in time, avoiding excessive accumulation in the collection box.

[0020] 1. The utility model sets a screening mechanism. Under the driving cooperation of the third motor, the ring gear and the cylindrical gear, the convex edge will rotate on the surface of the fixed circle, and then the screening circle will also rotate synchronously. A number of bearing areas will be formed between the inner circumferential wall of the screening circle and the partition plate. The bearing areas will carry the crushed plastic particles from the feeding channel. At the same time, the screening holes will filter the plastic particles that have been crushed small enough. The larger plastic particles that are not completely crushed and remain in the bearing areas will fall back into the crushing box under the action of gravity and be crushed again during the rotation of the screening circle until they can pass through the screening holes. This avoids the process of manually pouring the plastic particles in the collection box into the crushing box, saving time and effort.

[0021] 2. The utility model sets a vibration mechanism. During the rotation of the screening circle, the elastic metal sheet on the vibration plate will enter the next row of screening holes from the original screening holes, thereby achieving percussion vibration of the screening circle during the rotation, thereby improving the passing rate of fine plastic particles, effectively avoiding the situation where fine plastic particles cannot pass through the screening holes due to the accumulation of larger plastic particles, and greatly reducing limitations.

[0022] 3. The utility model sets a feeding mechanism and drives the auger to rotate through the rotation of the first motor, and then the auger transports the crushed plastic particles to the outside through the discharge port at the bottom of the collection box and collects them, thereby preventing the plastic particles from accumulating in the collection box, thereby greatly improving the practicality.

[0031] Reference Figure 1-Figure 4 The embodiment of the utility model proposes a plastic particle crushing device, including a collecting box 1, which is installed on a supporting frame 7. A feeding mechanism 2 is arranged in the collecting box 1, and the feeding mechanism 2 includes a placement box 21 fixedly connected to the outer wall of one side of the collecting box 1, and a first motor 22 is fixedly connected to the placement box 21. An auger 23 is rotatably connected in the collecting box 1, and one end of the auger 23 is fixedly connected to the output end of the first motor 22, and the other end of the auger 23 is connected to the inner wall of the collecting box 1 through a bearing. A discharge port is opened at the bottom of the collecting box 1 away from the first motor 22. The rotation of the first motor 22 drives the auger 23 to rotate, and then the auger 23 transports the crushed plastic particles to the outside through the discharge port at the bottom of the collecting box 1 and collects them, so as to prevent the plastic particles from accumulating in the collecting box 1.

[0032] Reference Figure 1-Figure 4A support column 3 is fixedly connected to the inner wall of the collecting box 1, and a crushing mechanism 4 is arranged on the support column 3. The crushing mechanism 4 includes a crushing box 41 fixedly connected to the support column 3, and the crushing box 41 is in a concave shape. A fixing ring 42 is fixedly connected to the outer wall of the crushing box 41. A feeding channel 43 is connected below the crushing box 41. The upper end of the feeding channel 43 is connected to the inner cavity of the crushing box 41, and the lower end of the feeding channel 43 faces the opening of the collecting box 1. Two crushing rollers 44 are rotatably connected in the feeding channel 43. The two crushing rollers 44 are meshed with each other, and a second motor 45 is fixedly connected to the outer wall of the feeding channel 43. The output end of the second motor 45 extends into the feeding channel 43 and is fixedly connected to one of the crushing rollers 44. The plastic particles to be crushed are poured into the crushing box 41. Since the crushing box 41 is directly connected to the feeding channel 43, the plastic particles will directly fall into the feeding channel 43. Driven by the second motor 45, the two meshing crushing rollers 44 in the feeding channel 43 will crush the plastic particles.

[0033] Reference Figure 1-Figure 4 A screening mechanism 5 is arranged outside the crushing mechanism 4, and the screening mechanism 5 includes a flange 54 rotatably connected to the outer peripheral wall of the fixed ring 42, and a ring gear 55 is fixedly connected to the outer peripheral wall of the flange 54. A third motor 56 is fixedly connected to one side of the crushing box 41, and a cylindrical gear 57 is fixedly connected to the output end of the third motor 56. The cylindrical gear 57 meshes with the ring gear 55. A screening ring 51 is fixedly connected to the side wall of the flange 54 away from the support column 3.

A plurality of evenly distributed screening holes 52 are provided on the outer surface of the screening ring 51, and a plurality of equally spaced partitions 53 are fixedly connected to the inner peripheral wall of the screening ring 51. The fixed ring 42, the flange 54 and the screening ring 51 are all circular, and the partitions 53 are all arranged toward the center of the circle. In cooperation with the drive of the cylindrical gear 57, the convex edge 54 will rotate on the surface of the fixed circle 42, and then the screening circle 51 will also rotate synchronously. A number of bearing areas will be formed between the inner wall of the screening circle 51 and the partition 53. The bearing areas will carry the crushed plastic particles from the discharge channel 43. At the same time, the screening holes 52 will filter the plastic particles that have been crushed to a small enough size. The larger plastic particles that are not completely crushed and remain in the bearing area will fall back into the crushing box 41 under the action of gravity and be crushed again during the rotation of the screening circle 51 until they can pass through the screening holes 52. At the same time, the partition 53 arranged toward the center of the circle can enable the plastic particles that fall into the bearing area to fall smoothly back into the crushing box 41, thereby avoiding falling to the outside.

During the rotation of the screening circle 51, the elastic metal sheets 62 on the vibration plate 61 will enter the next row of screening holes 52 from the original screening holes 52, thereby realizing the knocking and vibration of the screening circle 51 during the rotation, thereby improving the passing rate of fine plastic particles, and effectively avoiding the situation where fine plastic particles cannot pass through the screening holes 52 due to the accumulation of larger plastic particles.

[0035] The specific implementation method is as follows: when in use, the plastic particles to be crushed are poured into the crushing box 41. Since the crushing box 41 is directly connected to the feeding channel 43, the plastic particles will directly fall into the feeding channel 43. Under the drive of the second motor 45, the two meshing crushing rollers 44 in the feeding channel 43 will crush the plastic particles. The crushed plastic particles will fall from the feeding channel 43 into the bearing area formed by the inner wall of the screening circle 51 and the partition 53. At the same time, under the drive cooperation of the third motor 56, the ring gear 55 and the cylindrical gear 57, the convex edge 54 will rotate on the surface of the fixed circle 42, and then the screening circle 51 will also rotate synchronously. At the same time, the screening hole 52 will filter out the plastic particles that have been crushed small enough. The larger plastic particles that remain in the bearing area, that is, the incompletely crushed ones, will fall back into the screening circle 51 under the action of gravity during the rotation of the screening circle 51. The plastic particles in the crushing box 41 are crushed again until they can pass through the screening holes 52, avoiding the process of manually bringing the plastic particles in the collection box 1 into the crushing box 41, saving time and effort. During the rotation of the screening circle 51, the elastic metal sheet 62 on the vibration plate 61 will enter the next row of screening holes 52 from the original screening holes 52, thereby achieving the knocking and vibration of the screening circle 51 during the rotation, thereby improving the pass rate of fine plastic particles, and effectively avoiding the situation where fine plastic particles cannot pass through the screening holes 52 due to the accumulation of larger plastic particles, greatly reducing the limitations, and the plastic particles passing through the screening holes 52 will fall into the collection box 1, and at the same time, through the rotation of the first motor 22, the auger 23 is driven to rotate, and then the auger 23 transports the crushed plastic particles to the outside through the discharge port at the bottom of the collection box 1 and collects them, thereby preventing the plastic particles from accumulating in the collection box 1.
