Description

Technical Field

[0001] This utility model relates to the field of plastic filler recycling, and in particular to a uniform crushing device for plastic filler recycling. Background Technology

[0002] With the rapid development of the plastics industry, plastic products have been widely used in various fields. Plastic fillers, as key components for reinforcement, volume increase or to impart special properties, are added in large quantities to various plastic products. However, when these plastic products reach the end of their service life, a large amount of waste containing plastic fillers will be generated. If they are not properly recycled, it will not only cause a great waste of resources, but also cause serious pollution to the environment.

[0003] A uniform crushing device for recycling plastic fillers, disclosed in CN216609682U, includes a screening box, a crushing box, and a loading trolley. The crushing box is equipped with crushing rollers, etc. This device can remove iron filings from the recycled plastic fillers, thus avoiding affecting the recycling of plastic fillers. However, this device is difficult to automatically compress and feed plastic fillers of different specifications. It has insufficient constraint on the material during crushing, and the plastic fillers are easy to fall off. It requires manual holding and fixing for a long time or repeated picking and re-feeding for crushing. The operation is cumbersome, consumes manpower and time, and seriously affects the crushing efficiency.

[0004] Therefore, it is necessary to design a uniform crushing device for plastic filler recycling that can automatically clamp and compress plastic fillers of different specifications while crushing them, without the need to hold the material by hand, reduce the material volume, prevent the material from falling out, improve crushing efficiency, and reduce manual intervention. Utility Model Content

[0005] To overcome the shortcomings of the current device, such as difficulty in automatically compressing and feeding plastic fillers of different specifications, insufficient constraint on materials during crushing, easy loss of plastic fillers, and the need for manual handling for extended periods or repeated picking and refeeding, which is cumbersome, time-consuming, and severely affects crushing efficiency, this utility model provides a uniform crushing device for plastic filler recycling that can automatically clamp and compress plastic fillers of different specifications while crushing them, eliminating the need to hold the materials, reducing material volume, preventing material from falling out, improving crushing efficiency, and reducing manual intervention.

[0006] A uniform crushing device for recycling plastic filler includes a crushing and screening chamber, a first motor, a crushing head, a second motor, a rotating frame, a filter screen, a clamping assembly, a collecting assembly, and a moving assembly. Two first motors, one at the front and one at the back, are connected to the upper part of the crushing and screening chamber. The first motors and a processor are electrically connected via a control module. Crushing heads are rotatably connected to both the left and right sides of the crushing and screening chamber. The output shaft of the front first motor is connected to the right crushing head, and the output shaft of the rear first motor is connected to the left crushing head. A second motor is connected to the upper front part of the crushing and screening chamber. The second motor and the processor are electrically connected via a control module. A rotating frame is connected to the output shaft of the second motor, and the rotating frame is rotatably connected to the crushing and screening chamber. A filter screen is connected to the inner side of the lower part of the crushing and screening chamber. A clamping assembly for clamping and feeding the plastic filler is provided on the rotating frame. A collecting assembly for collecting the crushed plastic filler is provided at the lower part of the crushing and screening chamber. A moving assembly for moving and discharging the plastic filler is provided on the clamping assembly.

[0007] Furthermore, the clamping assembly includes a third motor, a bidirectional lead screw, connecting blocks, and clamping plates. The third motor is connected to the front right side of the rotating frame. The third motor and the processor are electrically connected through a control module. The output shaft of the third motor is connected to the bidirectional lead screw, which is rotatably connected to the rotating frame. Connecting blocks are threaded to both the front and rear ends of the bidirectional lead screw. The connecting blocks are slidably connected to the rotating frame. Clamping plates are connected to the connecting blocks, and the two clamping plates are slidably connected.

[0008] Furthermore, all the clamps are U-shaped.

[0009] Furthermore, the collection assembly includes a first collection frame, a second collection frame, an electric telescopic rod, and a scraper. The first collection frame is placed at the bottom of the crushing and screening chamber, and the second collection frame is slidably engaged at the lower left of the crushing and screening chamber. An electric telescopic rod is connected to the lower right side of the crushing and screening chamber. The electric telescopic rod and the processor are electrically connected through a control module. A scraper is connected to the telescopic end of the electric telescopic rod, and the scraper is slidably connected to the crushing and screening chamber.

[0010] Furthermore, the scraping frame is I-shaped.

[0011] Furthermore, the moving component includes a fourth motor and rollers. The lower part of each clamping plate is connected to the fourth motor. The fourth motor and the processor are electrically connected through a control module. Rollers are connected to the output shaft of each fourth motor, and the rollers are in contact with the adjacent clamping plates.

[0012] This utility model has the following advantages: 1. This utility model places the plastic filler on the clamping plate, then clamps the plastic filler by moving the clamping plate and compressing the plastic filler to reduce its volume. Then, the rotating frame rotates to make the clamping plate vertical, and the rollers rotate to drive the plastic filler to move and feed to contact the crushing head for crushing. This allows for the automatic clamping and compression of plastic fillers of different specifications while crushing them. There is no need to hold the material by hand, which reduces the material volume, prevents the material from falling out, improves crushing efficiency, and reduces manual intervention.

[0013] 2. This utility model separates plastic fillers by filtering them on a filter screen. Smaller plastic fillers fall into the first collection box for collection, while incompletely crushed plastic fillers remain on the filter screen. Then, a scraper pushes the incompletely crushed plastic fillers to fall into the second collection box for collection, and then pours them back into the crushing and screening chamber for crushing. This allows for screening while the plastic fillers are being crushed, and separates the incompletely crushed and crushed materials for collection, facilitating re-crushing and improving the uniformity of crushing.

[0022] A uniform crushing device for recycling plastic fillers, such as Figures 1-6 As shown, the device includes a crushing and screening chamber 1, a first motor 2, a crushing head 3, a second motor 4, a rotating frame 5, a filter screen 14, a clamping assembly, a collecting assembly, and a moving assembly. The upper part of the crushing and screening chamber 1 is connected to two first motors 2, one at the front and one at the back. The first motors 2 and the processor are electrically connected via a control module. Crushing heads 3 are rotatably connected to both the left and right sides of the crushing and screening chamber 1. The output shaft of the front first motor 2 is connected to the right crushing head 3, and the output shaft of the rear first motor 2 is connected to the left crushing head 3. The upper front part of the crushing and screening chamber 1 is connected to a second motor 4, which is electrically connected to the processor via a control module. The output shaft of the second motor 4 is connected to a rotating frame 5, which is rotatably connected to the crushing and screening chamber 1. A filter screen 14 is connected to the inner lower part of the crushing and screening chamber 1. The rotating frame 5 is equipped with a clamping assembly for clamping and feeding plastic fillers. The lower part of the crushing and screening chamber 1 is equipped with a collecting assembly for collecting the crushed plastic fillers. The clamping assembly is equipped with a moving assembly for moving and discharging the plastic fillers.

[0023] like Figure 1 , Figure 2 and Figure 5 As shown, the clamping assembly includes a third motor 6, a bidirectional lead screw 7, a connecting block 8, and a clamping plate 9. The third motor 6 is connected to the front right side of the rotating frame 5. The third motor 6 and the processor are electrically connected through a control module. The bidirectional lead screw 7 is connected to the output shaft of the third motor 6. The bidirectional lead screw 7 is rotatably connected to the rotating frame 5. The front and rear parts of the bidirectional lead screw 7 are threadedly connected to the connecting blocks 8. The connecting blocks 8 are slidably connected to the rotating frame 5. Each connecting block 8 is connected to a clamping plate 9. The two clamping plates 9 are slidably connected. The clamping plates 9 are all U-shaped to facilitate positioning.

[0024] like Figure 1 , Figure 3 and Figure 4As shown, the collection assembly includes a first collection frame 10, a second collection frame 11, an electric telescopic rod 12, and a scraper 13. The first collection frame 10 is placed at the lower part of the crushing and screening chamber 1. The second collection frame 11 is slidably engaged with the lower left part of the crushing and screening chamber 1. The electric telescopic rod 12 is connected to the lower right side of the crushing and screening chamber 1. The electric telescopic rod 12 and the processor are electrically connected through a control module. The scraper 13 is connected to the telescopic end of the electric telescopic rod 12. The scraper 13 is slidably connected to the crushing and screening chamber 1. The scraper 13 is I-shaped, which facilitates the scraping off of incompletely crushed plastic fillers.

[0025] like Figure 6 As shown, the moving component includes a fourth motor 15 and rollers 16. The lower part of each clamping plate 9 is connected to the fourth motor 15. The fourth motor 15 and the processor are electrically connected through a control module. Each output shaft of the fourth motor 15 is connected to a roller 16, and each roller 16 is in contact with the adjacent clamping plate 9.

[0026] When uniform crushing is required for plastic filler recycling, this device can be used. The crushing and screening chamber 1 is brought into contact with the ground, and the plastic filler is placed on clamping plates 9, which are U-shaped. The processor then starts the third motor 6 via the control module. The third motor 6 drives the bidirectional lead screw 7 to rotate, causing the connecting block 8 to move inward along the rotating frame 5 under the action of the screw thread. This, in turn, moves the clamping plates 9 to clamp and compress the plastic filler, reducing its volume. Then, the second motor 4 is started, driving the rotating frame 5 to rotate, making the clamping plates 9 vertical. Finally, the fourth motor 15 is started, driving the rollers 16 to rotate. Under the action of friction, the plastic filler is crushed... The material filler moves and contacts the crushing head 3. At the same time, the first motor 2 is started. The first motor 2 drives the crushing head 3 to rotate and crush the plastic filler. After crushing, the second motor 4 reverses the operation, causing the rotating frame 5 to rotate and reset. Then, the third motor 6 reverses the operation, causing the bidirectional lead screw 7 to rotate in the opposite direction. Under the action of the thread, the connecting block 8 and the clamping plate 9 move outward and reset at the same time. The above operation is repeated to continue to place the plastic filler on the clamping plate 9 for clamping, feeding and crushing. In this way, it can automatically clamp plastic filler of different specifications for compression and feeding while crushing. There is no need to hold the material, which reduces the material volume, prevents the material from falling out, improves crushing efficiency and reduces manual intervention. The crushed plastic filler falls onto the filter screen 14 for filtration and separation, causing smaller plastic fillers to fall into the first collection frame 10 for collection, while the incompletely crushed plastic fillers remain on the filter screen 14. Then, the electric telescopic rod 12 is activated, which drives the scraper 13 to move, pushing the incompletely crushed plastic fillers to fall into the second collection frame 11 for collection. The scraper 13 is I-shaped. The electric telescopic rod 12 then reverses its operation, causing the scraper 13 to move and reset. Next, the second collection frame 11 is moved and removed, and the incompletely crushed plastic fillers in the second collection frame 11 are poured into the crushing and screening chamber 1 for re-crushing. This allows for screening while the plastic fillers are being crushed, and separates the incompletely crushed and crushed materials for collection, facilitating re-crushing and improving crushing uniformity. The above operation is then repeated to continue clamping, feeding, crushing, screening, and classifying the plastic fillers until crushing is complete. Finally, the first motor 2, the second motor 4, the third motor 6, the electric telescopic rod 12, and the fourth motor 15 are turned off.
