Technical Field
[0001] This utility model relates to the field of plastic recycling technology, specifically to a plastic fragment recycling device. Background Technology
[0002] Plastics are important organic synthetic polymer materials with a wide range of applications. Due to their non-biodegradability, plastics have become the number one enemy of mankind. Therefore, the classification, recycling and processing of plastics are of great importance to improve the environment. In the process of recycling plastics, large plastics need to be crushed, which requires the use of plastic crushing equipment.
[0003] Existing plastic crushing devices use a motor to drive the crushing rollers to rotate, causing two crushing rollers to rotate in opposite directions to crush the plastic. However, in actual use, the crushed plastic falls to the bottom of the crushing box and is then discharged uniformly. This method easily causes plastic fragments to clog the discharge port, leading to subsequent shutdowns for maintenance and affecting crushing efficiency. Therefore, a plastic fragment recycling device for plastic is proposed. Utility Model Content

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example: Please refer to the following: Figures 1-6This utility model provides a technical solution: a plastic fragment recycling device, including a crushing box 1, a cavity 2 formed on the outer right side of the crushing box 1, a conveyor 3 provided on the inner bottom surface of the crushing box 1, one end of the conveyor 3 extending to the cavity 2 outside the crushing box 1, support feet fixedly connected to the four corners of the bottom of the crushing box 1, a base plate 4 fixedly connected between the two support feet on the right side, two side plates symmetrically arranged on the top outer surface of the base plate 4 fixedly connected, a reciprocating screw 5 rotatably connected between the two side plates, a first motor 6 fixedly installed on the outer right side surface of the right side plate, the output end of the first motor 6 being connected to the reciprocating screw 5... The lead screw 5 is fixedly connected, and a threaded block is threadedly connected to the outer surface of the reciprocating lead screw 5. A placement plate 7 is fixedly connected to the top outer surface of the threaded block, and a receiving box 8 is placed on the top outer surface of the placement plate 7. Specifically, the crushed plastic falls onto the conveyor 3, which transports the crushed plastic to the receiving box 8. The first motor 6 drives the reciprocating lead screw 5 to rotate, which in turn drives the threaded block to move back and forth, causing the receiving box 8 to move back and forth. This ensures that the crushed plastic enters the receiving box 8 evenly, improving space utilization and allowing the plastic to be discharged simultaneously with the crushing process, thus preventing blockage at the discharge port.
[0025] Furthermore, a first gear 9 is rotatably connected to the front outer surface of the crushing box 1, and an L-shaped mounting plate is fixedly connected to the front outer surface of the crushing box 1. A second motor 10 is fixedly mounted on the outer surface of the L-shaped mounting plate, and the output end of the second motor 10 is fixedly connected to the first gear 9. Racks 11 are movably meshed on both the upper and lower outer surfaces of the first gear 9, and hook-shaped rods 12 are fixedly connected to the outer surfaces of both racks 11. Two top covers 13 are movably disposed on the top outer surface of the crushing box 1, and the two hook-shaped rods 12 are fixedly connected to the two top covers 13 respectively. Specifically, in... When the plastic is conveyed into the crushing chamber 1, the second motor 10 is turned on first. The second motor 10 drives the first gear 9 to rotate. The first gear 9 drives the rack 11 to move away from each other. The rack 11 drives the hook rod 12 to open the two top covers 13. After the material is unloaded, the second motor 10 rotates in the opposite direction. The second motor 10 drives the first gear 9 in the opposite direction, so that the first gear 9 drives the two racks 11 to move closer to each other, so that the top covers 13 are closed. This prevents plastic fragments from splashing out of the feed inlet and causing safety hazards during crushing.
[0026] Furthermore, four rotating shafts 14 are rotatably connected to the inner surface of the crushing box 1. A third motor 24 is fixedly installed on the rear outer surface of the crushing box 1. The output end of the third motor 24 is fixedly connected to the upper left rotating shaft 14. The four rotating shafts 14 are arranged in two pairs, one above the other. The outer surfaces of the two upper rotating shafts 14 are fixedly fitted with a winding roller 15. Several winding blades 16 are fixedly installed on the outer surface of the winding roller 15. Specifically, when the two upper rotating shafts 14 rotate, they drive the winding roller 15 and the winding blades 16 to rotate in opposite directions, thereby pre-crushing the plastic.
[0027] Furthermore, crushing rollers 17 are fixedly sleeved on the outer surfaces of the two lower rotating shafts 14, and several crushing blades 18 are fixedly arranged on the outer surfaces of the crushing rollers 17. Specifically, when the two lower rotating shafts 14 rotate, they drive the crushing rollers 17 and the crushing blades 18 to rotate in opposite directions, thereby crushing the plastic.
[0028] Furthermore, two support shafts are rotatably connected to the front outer surface of the crushing box 1. First transmission wheels 20 are fixedly sleeved on the outer surfaces of the two upper rotating shafts 14 and the two support shafts. First belts 22 are movably wound between the two left-side first transmission wheels 20 and between the two right-side first transmission wheels 20. Second transmission wheels 21 are fixedly sleeved on the outer surfaces of the two lower rotating shafts 14 and the two support shafts. Second belts 23 are movably wound between the two left-side second transmission wheels 21 and between the two right-side second transmission wheels 21. Specifically, the third motor 24 drives the rotating shaft 14 of its output shaft to rotate, causing the winding roller 15 and the first transmission wheels 20 on it to rotate. Under the action of the first belt 22, the first transmission wheels 20 on the support shaft rotate, thereby causing the second gear 19 to rotate. The second gear 19 drives another second gear 19 to rotate, causing the first transmission wheel 20 on another support shaft to rotate. The other winding roller 15 rotates under the left and right influence of the other first belt 22. When the two support shafts rotate, they respectively drive the second transmission wheels 21 on them to rotate. Under the action of the second belt 23, the two lower rotating shafts 14 rotate.
[0029] Furthermore, a second gear 19 is fixedly sleeved on the outer surface of both support shafts, and the outer surfaces of the two second gears 19 are movably meshed with each other. Specifically, the two second gears 19 mesh with each other, causing the two second gears 19 to rotate in opposite directions.
[0030] Furthermore, two sets of support blocks are fixedly connected to the front outer surface of the crushing box 1. Each set of support blocks consists of two blocks. A first sliding rod is fixedly connected to the outer surface of each pair of support blocks. A slider is fixedly connected to the outer surface of each rack 11. The two sliders are movably mounted on the outer surface of the two first sliding rods. Specifically, during the process of the first gear 9 driving the rack 11 to move, the two sliders slide on the outer surface of the two first sliding rods respectively, so that the rack 11 moves stably.
[0031] Furthermore, two fixing blocks are fixedly connected to the rear outer surface of the crushing box 1, and a second sliding rod is fixedly connected between the two fixing blocks. Inverted L-shaped plates are fixedly connected to the rear outer surfaces of the two top covers 13. The two inverted L-shaped plates are movably sleeved on the outer surface of the second sliding rod. Specifically, when the top cover 13 moves, the inverted L-shaped plates slide on the outer surface of the second sliding rod, so that the top cover 13 moves stably.
[0032] Working Principle: In use, the plastic to be crushed is conveyed into the crushing chamber 1. The third motor 24 is turned on, driving the rotating shaft 14 of its output shaft to rotate, causing the winding roller 15 and the first transmission wheel 20 on it to rotate. Under the action of the first belt 22, the first transmission wheel 20 on the support shaft rotates, thereby causing the second gear 19 to rotate. The second gear 19 drives another second gear 19 to rotate, causing the first transmission wheel 20 on another support shaft to rotate. The other winding roller 15 rotates under the influence of the other first belt 22, thus causing the two winding rollers 15 to drive the winding blades 16 to rotate in opposite directions, crushing the plastic. When the two support shafts rotate, they drive the second transmission wheels 21 on them to rotate. Under the action of the second belt 23, the two crushing rollers 17 drive the crushing blades 18 to rotate in opposite directions. The crushing blades 18 further crush the plastic. The crushed plastic falls onto the conveyor 3, which transports the crushed plastic to the receiving box 8. The first motor 6 drives the reciprocating screw 5 to rotate. The rotation of the reciprocating screw 5 drives the threaded block to move back and forth, causing the receiving box 8 to move back and forth. This allows the crushed plastic to enter the receiving box 8 evenly, improving space utilization. This allows the plastic to be discharged while being crushed, preventing blockage at the discharge port.
[0033] When the plastic is conveyed into the crushing chamber 1, the second motor 10 is turned on first. The second motor 10 drives the first gear 9 to rotate. The first gear 9 drives the rack 11 to move away from each other. The rack 11 drives the hook rod 12 to open the two top covers 13. After the material is unloaded, the second motor 10 rotates in the opposite direction. The second motor 10 drives the first gear 9 in the opposite direction, so that the first gear 9 drives the two racks 11 to move closer to each other, so that the top covers 13 are closed. This prevents plastic fragments from splashing out of the feed inlet and causing safety hazards during crushing.
