Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic processing equipment technology, and more specifically, to a plastic crushing, feeding, and weighing structure. Background Technology
[0002] Plastic crushing is the process of breaking waste plastics or scraps into fine particles using mechanical force. It typically includes pretreatment, coarse crushing, fine crushing, screening, and dust removal. First, after the plastics are sorted and cleaned to remove impurities, they are sent to a shredder for coarse crushing. Then, they are further refined by a high-speed rotating cutter head or hammer mill, and finally, they are graded by a vibrating screen to obtain uniform recycled plastic particles.
[0003] Traditional plastic crushers rely mainly on manual dumping for feeding. Operators manually move the plastic to the crusher inlet and pour it in. When feeding manually, operators need to be close to the high-speed rotating crushing blades, which poses a risk of hands or tools accidentally entering the feed inlet, easily leading to serious workplace accidents. Plastic fragments or dust may also fly, threatening workers' health. The manual handling, weighing, and dumping process is time-consuming, making it difficult to meet the needs of continuous production and resulting in low production efficiency. Utility Model Content

[0016] 3. Beneficial effects
[0017] Compared with existing technologies, this utility model provides a plastic crushing, feeding, and weighing structure, which has the following beneficial effects:
[0018] This plastic crushing and weighing structure weighs the plastic on a weighing device. Once the weight meets the process requirements, it pushes the carrier box so that the docking box is fully fitted onto the docking block. Then, the lifting threaded rod is controlled by a lifting motor to rotate, causing the lifting transmission block to rise. Two connecting rods then lift the tilting control box, raising the docking block and the carrier box to a specific height. The transmission threaded rod is then controlled by a feed motor to rotate, moving the feed transmission block. This moves the lifting control box, tilting control box, and carrier box above the inlet of the plastic crusher. The transmission worm is then controlled by a tilting motor to rotate the transmission worm wheel. The docking block, through the docking box, drives the carrier box to rotate, thus emptying all the plastic from the carrier box into the plastic crusher. The weighing device detects the plastic weight, ensuring that each feeding meets the process requirements. This automated feeding eliminates the need for manual dumping, preventing the risk of hands or tools accidentally entering the high-speed rotating crushing blades, reducing labor intensity, and significantly improving production efficiency.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

A transmission threaded rod 18 is rotatably connected between the inner walls of both sides of the feeding control box 4. A feeding transmission block 17 is threaded onto the transmission threaded rod 18. A lifting control box 5 is connected to the top of the feeding transmission block 17 via a fixed rod. A lifting threaded rod 14 is rotatably connected between the upper and lower inner walls of the lifting control box 5. A lifting transmission block 11 is threaded onto the lifting threaded rod 14. Two connecting rods 10 are fixedly connected to one outer surface of the lifting transmission block 11. A tilting control box 7 is fixedly connected to one end of each connecting rod 10. A transmission worm gear 13 is rotatably connected between the inner walls of both sides of the tilting control box 7. A docking block 8 is rotatably connected to one outer surface of the tilting control box 7 and is fixedly connected to the transmission worm gear 13. A transmission worm 12 is rotatably connected between the front and rear inner walls of the tilting control box 7 and meshes with the transmission worm gear 13.
[0030] Weighing device 2 is fixedly installed on the top of the base plate 1. A bearing box 3 is provided on the top of the weighing device 2. A docking box 6 is fixedly connected to one side of the outer surface of the bearing box 3. The docking box 6 is slidably sleeved on the docking block 8.
[0031] In a specific embodiment of this utility model, the inlets of commonly available plastic crushers are angled upwards. The bearing box 3 is used to hold the plastic to be crushed. After the weight of the plastic is measured on the weighing device 2 and it is determined that the weight meets the process requirements, the bearing box 3 is pushed so that the docking box 6 is completely fitted onto the docking block 8. Then, the lifting threaded rod 14 is controlled to rotate, driving the lifting transmission block 11 to rise. The two connecting rods 10 drive the tilting control box 7 to rise, so that the docking block 8 drives the bearing box 3 to rise to a specific height. Then, the transmission threaded rod 18 is controlled to rotate, driving the feeding transmission block 17 to move. The movement causes the lifting control box 5 to move the tilting control box 7 and the carrying box 3 to the inlet of the plastic crusher. Then, the transmission worm gear 12 is controlled to rotate, driving the transmission worm wheel 13 to rotate. The docking block 8 drives the carrying box 3 to rotate through the docking box 6, thereby pouring all the plastic inside the carrying box 3 into the plastic crusher. The weight of the plastic is detected by the weighing device 2 to ensure that each feeding meets the process requirements. At the same time, the feeding of plastic crushing is automated, eliminating the need for manual dumping of plastic, eliminating the risk of hands or tools accidentally entering the high-speed rotating crushing blades, reducing labor intensity and greatly improving production efficiency.

[0033] In this embodiment, the feed motor 20 is started by controlling the feed motor 20 to drive the transmission threaded rod 18 to rotate.
[0034] Specifically, two support rods 19 are fixedly connected between the inner walls of the two sides of the feed control box 4, and the feed transmission block 17 is slidably sleeved on the two support rods 19.

[0040] Specifically, a tilting motor 9 is fixedly installed on one outer surface of the tilting control box 7, and the output end of the tilting motor 9 is fixedly connected to the transmission worm gear 12.
[0041] In this embodiment, by controlling the tilting motor 9 to start, the transmission worm gear 12 can be driven to rotate.
[0042] Working principle: The bearing box 3 is used to hold the plastic to be crushed. After the weight of the plastic is weighed on the weighing device 2 and it is determined that the weight of the plastic meets the process requirements, the bearing box 3 is pushed so that the docking box 6 is completely fitted onto the docking block 8. Then, the lifting threaded rod 14 is controlled to rotate by the lifting motor 15, which drives the lifting transmission block 11 to rise. The two connecting rods 10 drive the tilting control box 7 to rise, so that the docking block 8 drives the bearing box 3 to rise to a specific height. Then, the transmission threaded rod 18 is controlled to rotate by the feed motor 20, which drives the feed transmission block 17 to move, so that the lifting control box 5 drives the tilting control box 7 and the bearing box 3 to move above the inlet of the plastic crusher. Then, the transmission worm gear 12 is controlled to rotate by the tilting motor 9, which drives the... The rotating worm gear 13 drives the docking block 8 to rotate the bearing box 3 via the docking box 6, thereby pouring all the plastic inside the bearing box 3 into the plastic crusher. The weight of the plastic is detected by the weighing device 2 to ensure that each feeding meets the process requirements. This achieves automated feeding of plastic crushing, eliminating the need for manual dumping of plastic and preventing the risk of hands or tools accidentally entering the high-speed rotating crushing blades. It reduces labor intensity and greatly improves production efficiency. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power component and the power supply are common knowledge in the field. Since this utility model is mainly used to protect the mechanical device, the control method and wiring layout will not be explained in detail.
