Description

Technical Field

[0001] The utility model relates to the technical field of crushers, and particularly to a feeding mechanism for a crusher. Background Art

[0002] During the processing of plastic products, it is usually to first make complete plastic sheets, plastic films or plastic pipes, etc., and then cut and process them into several single plastic products of the required specifications. Among them, a large amount of plastic waste will be generated during the cutting and processing, and these wastes can be recycled by reheating and remelting.

[0003] Based on the above processing process, when recycling the plastic waste after cutting, it is necessary to first perform crushing treatment to make it into small volume particles with uniform fineness for subsequent hot melting. For the production of plastic cups, that is, after cutting the bagged coil materials, the remaining waste is also in the form of coils, so it needs to go through multi-stage crushing treatment, first broken into loose blocks, and then processed into granular by a crusher.

[0004] However, in industrial production, due to the large processing volume, in the process of sending the broken coils into the crusher after breaking them into blocks, the current processing method is to use a suction device to send the block waste into the crusher at a constant speed. However, due to the irregular shape of the waste itself, it is very easy to cause the problem of blockage of the suction device, which is not only difficult to repair, but also greatly affects the production efficiency. Summary of the Utility Model

After the block waste falls onto the surface of the conveying table through the discharge port, under the action of a spiral push rod and a stepped conveyor belt body, the materials can be sent into the crusher evenly and at a constant speed. The feeding mechanism has a simple structure and is convenient to dredge in case of congestion.

[0030] Among them, the crusher 3 uses a common crusher for plastic shredding at present. Most of them convey materials from top to bottom, that is, the materials are fed into the feeding port at the top of the crusher 3, and under the action of gravity, they are conveyed downward in the vertical direction. During the falling process, they pass through the treatment of the crushing mechanism in turn, and finally the finely crushed uniform granular materials can be sent out from the bottom of the crusher 3.

The control module 62 is a controller, and the controller can be selected from a single-chip microcomputer (such as 8051 series single-chip microcomputers, STM32 series single-chip microcomputers). The pressure sensor 61 is used to monitor the overall situation of the material quantity on the stepped conveyor belt body 5, and adjust the rotation speed of the spiral push rod 4 according to the amount of the material, so as to adjust the conveying rate of the material. The power supply module 64 can be an industrial power supply that provides power for the above-mentioned devices. The specific selected models, installation positions, etc. of the above-mentioned devices can be selected by those skilled in the art according to the convenience of actual production by using conventional technical means.
