Description

Technical Field

[0001] This application relates to the field of plastic crusher technology, and particularly to a high-power plastic crusher. Background Technology

[0002] A crusher is a machine that crushes large solid raw materials to the required size. The external forces applied to the solid during the crushing process include shearing, impact, crushing, and grinding. Shearing is mainly used in coarse crushing and pulverizing operations, and is suitable for crushing or pulverizing tough or fibrous materials and large pieces.

[0003] A search revealed a patent document with authorization announcement number CN110978334B disclosing a high-powered pulverizer for plastic materials, comprising a frame, a power mechanism, a feeding mechanism, a pulverizing mechanism, and a discharge mechanism. The feeding mechanism includes a hopper, an extension plate, and a top cover. The hopper is shaped like a bucket, wider at the top and narrower at the bottom. The extension plate extends obliquely, and the top cover is hinged to the hopper, allowing partial closure of the hopper's inlet. The pulverizing mechanism includes a processing box, a main shaft, a drive wheel, blades, bearing seats, and a filter screen. The discharge mechanism includes a discharge hopper, a transition pipe, a sieve plate, a fan, a waste bin, and a discharge box. The discharge hopper is connected to the bottom of the processing box of the pulverizing mechanism. The transition pipe is horizontally positioned and, after connecting to the discharge hopper, feeds the pulverized plastic particles into the discharge box. A sieve plate is located at the bottom of the transition pipe, and a fan is located on the side of the waste bin, directing the airflow towards the discharge box. The size of the feed inlet is adjustable and can remove metal debris, preventing damage to the injection molding machine.

[0004] In practical use, it has been found that existing equipment, due to the narrow internal space of the feeding pipe, is prone to clogging when the crushed plastic granules fall under gravity, caused by friction between the granules, electrostatic adsorption, or moisture adhesion. Once clogging occurs, not only is manual disassembly and cleaning required, but forced operation may also damage the internal structure of the equipment, increasing maintenance costs and equipment failure rate. Therefore, we have proposed a high-powered plastic pulverizer to solve the above problems. Utility Model Content

A first transmission mechanism is provided between the reciprocating lead screw 102 and the output shaft of the motor 101.

[0038] Specifically, the first transmission mechanism includes a first transmission wheel 7, a second transmission wheel 701, and a first transmission belt 702. The first transmission wheel 7 is fixedly sleeved on the output shaft of the motor 101 and is located inside the function box 1. The second transmission wheel 701 is fixedly sleeved on the reciprocating lead screw 102 and is located on the left side of the lead screw seat 103. The first transmission wheel 7 and the second transmission wheel 701 are connected by the same first transmission belt 702. The diameter of the first transmission wheel 7 is smaller than the diameter of the second transmission wheel 701.

[0039] Specifically, the conveying mechanism includes a conveying shaft 401 and a spiral blade 402. The same conveying shaft 401 is rotatably mounted on the inner left side of the functional box 1 and the inner right side of the conveying chamber 4.

[0041] Specifically, the unblocking mechanism includes a slide rod 501 and a lever 502. The slide rod 501 is fixedly installed on the right side of the screw seat 103. The right end of the slide rod 501 extends into the discharge pipe 5. The lever 502 is fixedly installed on the top of the slide rod 501 and is located inside the discharge pipe 5.

[0042] Specifically, a material collection box 8 is provided below the conveying bin 4, and a discharge pipe 9 is provided at the bottom of the conveying bin 4. The discharge pipe 9 is compatible with the material collection box 8.

[0043] Specifically, a controller is installed on the front side of the function box 1, and the controller is electrically connected to the motor 101.

[0044] Specifically, the same guide plate 10 is provided on the inner wall of the right side and the inner wall of the bottom of the crushing chamber 2, and the guide plate 10 is adapted to the discharge pipe 5.

[0045] In this application, during operation, the controller first starts the motor 101, and its output shaft can drive the crushing roller 201 to rotate at high speed. The crushing blade 202 fixed on the crushing roller can form a high-speed rotating cutting surface, which can powerfully cut and impact crush the plastic raw materials falling from the hopper 3 through the feed pipe 301. By utilizing the sharp edge of the blade and the high-speed rotational kinetic energy, large pieces of plastic can be decomposed into fine particles to meet the needs of subsequent processing. The crushed material gathers at the bottom of the crushing chamber 2 along the guide plate 10 under the action of gravity. The inclined design of the guide plate 10 can ensure that the material slides smoothly to the inlet of the discharge pipe 5 and avoids being stuck in the dead corner of the chamber wall.

[0046] While the motor 101 drives the crushing mechanism, its output shaft can transmit power to the reciprocating screw 102 through the first transmission mechanism composed of the first transmission wheel 7, the first transmission belt 702, and the second transmission wheel 701. Since the diameter of the first transmission wheel 7 is smaller than that of the second transmission wheel 701, a speed reduction transmission can be formed, enabling the reciprocating screw 102 to rotate at a suitable speed. This drives the screw seat 103 to make left and right reciprocating linear motion along the axis of the reciprocating screw 102. It can also drive the slide bar 501 and the lever 502 to move synchronously with the screw seat 103, enabling the lever 502 to move left and right reciprocally within the feed pipe 5. This can prevent the crushed material from accumulating or adhering to the inner wall of the feed pipe, especially for plastic particles with high humidity or stickiness. This can effectively break up lumps, unclog the pipes, ensure smooth feeding, avoid downtime due to blockage, and improve the continuous operation capability of the equipment.

[0047] In addition, the reciprocating screw 102 can transmit power to the conveying shaft 401 through the second transmission mechanism composed of the third transmission wheel 703 and the second transmission belt 704; the spiral blades 402 on the conveying shaft rotate with the shaft, which can generate a spiral pushing force, and can realize the material falling from the discharge pipe 5 from one end of the conveying bin 4 to the other end; it can ensure that the material moves evenly and stably towards the discharge pipe 9, and finally falls into the collection box 8 for collection, and can achieve the purpose of reducing material dust flying.
