Convenient-to-use efficient crushing device for glass fiber powder production

Abstract

The invention relates to the technical field of crushing processing for glass fiber powder production, and discloses a convenient-to-use efficient crushing device for the glass fiber powder production. The crushing device comprises a working box, wherein the top of the working box communicates with a feeding hopper, the feeding hopper extends into the working box, and the inner side wall of the working box is fixedly connected with a glass fiber guide block; and a motor is fixedly connected to the top of the working box, a rotating shaft is fixedly connected to the output end of the motor, thebottom end of the rotating shaft penetrates through the top of the working box and extends into the working box, and three crushing cutters are fixedly connected to the outer circle face of the rotating shaft at equal intervals. The convenient-to-use efficient crushing device for the glass fiber powder production solves the problems that the time for crushing glass fibers is short, the crushing effect is poor, the needed length is difficult to achieve and the crushing uniformity cannot be guaranteed due to the fact that most existing crushing devices enable glass fibers to be crushed throughone or more crushing procedures under the action of self-gravity.

Description

technical field [0001] The invention relates to the technical field of crushing processing for glass fiber powder production, in particular to an easy-to-use high-efficiency crushing device for glass fiber powder production. Background technique [0002] Glass fiber powder is a product obtained by crushing and sieving chopped fiberglass fiber. It can significantly enhance various properties of the product, such as enhancing the hardness and tear resistance of the product, and can be used in friction materials. Reduce the wear of friction materials, change the friction performance, improve the friction effect, etc. [0003] Since the chopped glass fiber is to be crushed into powder, the requirements for the crushing device are very high, and most of the existing crushing devices put the glass fiber into the crushing device, and then the glass fiber is crushed under the action of its own gravity. After one to several crushing processes, it is then discharged from the discharg...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an easy-to-use high-efficiency crushing device for the production of glass fiber powder, which solves the problem that most of the existing crushing devices allow the glass fiber to go through one to several stages of crushing under the action of its own gravity. The process is crushed, so that the time for the glass fiber to be crushed is short, the crushing effect is not good, it is difficult to reach the required length, and the crushing uniformity cannot be guaranteed.
