Combined shearing tool for plastic granulator

Abstract

The invention provides a combined shearing tool for a plastic granulator. The combined shearing tool comprises a hollow cutter base, blades, a cutter shaft and limiting blocks. The hollow cutter base is connected with the blades and the cutter shaft. The outer edge of the hollow cutter base is of a sawtooth shape. Wheel teeth of the hollow cutter base are conical teeth. Each blade comprises a cutting edge mechanism, a connecting block and a locating block. Each cutting edge mechanism is provided with a first protruding block and a first screw hole. Each connecting block is provided with a first screw hole, a second protruding block and a first groove corresponding to the first protruding block. Each locating block is provided with a first screw hole, a third screw hole and a second groove corresponding to the second protruding block. The blades are fixed through the limiting blocks. Each limiting block is provided with a second screw hole. The hole diameter of each second screw hole is the same as that of each first screw hole. The shearing tool is of a combination type, the length of the blades is determined conveniently according to actual use, and meanwhile the interval between the blades can be adjusted. The combined shearing tool is reasonable in design, flexible and convenient to use and beneficial for improving production efficiency.

Description

technical field [0001] The invention relates to the technical field of plastic pelletizers, in particular to a combined shearing tool of a plastic pelletizer. Background technique [0002] In the process of producing plastic particles, it is necessary to use a pelletizer to cut the strips produced by the extruder, so as to facilitate packaging and secondary processing. The role of the pelletizer is to cut the resin extruded from the template into pellets of a specific shape. The granulator is mainly composed of three parts: the motor that drives the cutter to rotate, the hydraulic unit that controls the movement of the granulation trolley, and the hydraulic unit that controls the distance between the cutter and the template. [0003] The pelletizing cutter is generally set up vertically or rollingly, and one end sends the raw material that is initially formed through a conveyor belt or other conveying device, and the motor drives the cutter to move repeatedly or roll to cut...

AI Technical Summary

Problems solved by technology

In the prior art, the granulator cuts the granules with standard specifications, and the cutting tool specifications are fixed. When it is necessary to process materials with different specifications, it is very inconvenient to replace the granulator for processing.

During the long-term use of the granulator, the cutter teeth of the cutter are worn due to collision with the material, and often need to be replaced. However, when only a few cutter teeth are worn, the entire cutter must be replaced, which is costly and has low effective utilization. High, it is troublesome to disassemble the tool holder, which is not conducive to the disassembly of the maintenance personnel
