Description

Technical Field

[0001] The utility model relates to the technical field of plastic woven bag processing, in particular to a multi-stage crushing device for plastic woven bag raw materials. Background Art

[0002] The raw materials used in the processing of plastic woven bags are mostly recycled waste plastic products. When processing plastic products, the raw materials need to be crushed, so corresponding crushing devices are needed;

[0003] In the actual use process of the existing raw material crushing device of plastic woven bags, a motor is used to drive the crushing roller to rotate, so as to crush the plastic by the crushing roller. However, in the crushing process, the presence of large plastic pieces will consume a lot of the crushing blades, which will cause certain damage to the blades, affecting the service life of the blades, and there is a situation of incomplete crushing. Therefore, we propose a multi-stage crushing device for plastic woven bag raw materials. Utility Model Content

[0004] The utility model aims to provide a multi-stage crushing device for plastic woven bag raw materials, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a multi-stage crushing device for plastic woven bag raw materials, comprising a box body, crushing rollers are rotatably installed on both sides of the inner cavity of the box body, a crushing motor is fixed at the end of the crushing roller on the outer wall of the box body corresponding to the end of the crushing roller, and the transmission shaft of the crushing motor passes through the box body and is fixedly connected to the end of the crushing roller, a crushing roller is rotatably installed on the lower side of the two crushing rollers, a crushing motor is fixed at the outer wall of the box body corresponding to the crushing roller, the transmission shaft of the crushing motor passes through the box body and is fixedly connected to the crushing roller, a plurality of evenly distributed crushing blades are fixed on the outer wall of the crushing roller, and a screen is fixed on the lower side of the inner cavity of the box body near the crushing blades.

[0006] By adopting the above technical solution, in the actual use process, the material is introduced into the inner cavity of the box body, and the plastic raw materials are initially crushed by two crushing rollers. After the crushing is completed, the crushed material will continue to fall and fall onto the crushing roller. The crushing motor is used to drive the crushing roller to rotate, so that the crushing blade is used to crush the material. The crushed material will be screened through the screen, so that qualified particles are discharged, and plastic pieces with larger particles will be crushed repeatedly to ensure the thoroughness of the crushing.

[0007] As a preferred embodiment of the utility model, a feed hopper is fixedly connected to the middle of the top of the box body, guide plates are hinged on both sides of the inner cavity of the box body, an electric push rod is hinged on one side wall of the guide plate, and the outer end of the electric push rod is fixedly connected to the inner wall of the box body.

[0008] By adopting the above technical solution, when there is no continuous material introduction, the electric push rod will drive the material guide plates on both sides to close, thereby preventing debris from flying.

[0009] As a preferred embodiment of the utility model, an infrared radiation switch is fixed to the inner wall of the feed hopper.

[0010] By adopting the above technical solution, the material is introduced into the hopper. At this time, the falling material will trigger the infrared radiation switch, thereby starting the electric push rod to drive the guide plates on both sides to open.

[0011] As a preferred embodiment of the present invention, a base is fixed to the bottom of the box.

[0012] By adopting the above technical solution and setting the base, the overall placement of the device is highly stable.

[0013] As a preferred embodiment of the present utility model, a material guide block is fixed at the bottom of the inner cavity of the box body, and a material outlet is opened at the tail end of the material guide block corresponding to the box body.

[0014] By adopting the above technical solution, the qualified materials after crushing fall onto the surface of the guide block, and then are guided out of the box along the inclined surface of the guide block, thereby realizing material discharge.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The multi-stage crushing device for plastic woven bag raw materials of the technical solution of the present application performs preliminary crushing of the recycled plastic products by crushing rollers, crushing them into smaller plastic pieces, and then crushing them by crushing blades, thereby significantly improving the crushing effect, and at the same time greatly reducing the consumption of the blades, playing an effect of protecting the blades and extending the service life of the blades;

[0017] The guide plates on both sides can be used to drive the electric push rod to close when the material is introduced, thereby preventing debris from flying to the outside of the equipment and polluting the surrounding environment, and also preventing the scale from splashing onto the staff and causing harm to them. In addition, the infrared beam switch is used to automatically control the electric push rod, thereby improving the convenience of using the device. BRIEF DESCRIPTION OF THE DRAWINGS
