Glass fiber cutting device

Abstract

The invention discloses a glass fiber cutting device. The glass fiber cutting device comprises a rack, a motor, a material collecting box and second knife holders, wherein a cutting box is arranged above the rack; two groups of second knife holders are symmetrically arranged on the left side and the right side inside the cutting box, and form a U-shaped cutting groove; a long shaft is horizontally and longitudinally arranged in the middle of the U-shaped cutting groove, and is connected to the motor in a driving mode; a first knife holder is fixedly arranged on the outer side of the long axis in a sleeving mode, wherein the long shaft and the first knife holder are respectively arranged in the cutting box; a plurality of groups of cutters are uniformly arranged on the circumference of the first knife holder at intervals; two groups of static cutters are respectively arranged in the middle of the side, close to the long axis, of the two groups of second knife holders; horizontal gaps are formed between the cutters and the static cutters; the lower outlet of the cutting box is connected to the material collecting box. The glass fiber cutting device is simple in structure, convenient to operate and low in use cost and maintenance cost, and a plurality of groups of knife holders and cutters are arranged, so that the cutting quality of glass fibers is improved, the discharging is more uniform through the arranged material collecting box, and materials are conveniently collected.

Description

technical field [0001] The invention relates to a cutting machine, in particular to a glass fiber cutting device. Background technique [0002] At present, chopped glass fibers are also called glass fiber chopped strands. Because glass fiber chopped strands have good cost performance, they are especially suitable for use as reinforcing materials for automobiles, trains, and ship shells in line with resins; they are used for high temperature resistant needles. Needle felt, car sound-absorbing sheet, etc., have a very wide range of uses. In production, chopped glass fiber is made by manual cutting or mechanical cutting of glass fiber filaments. The blades on the common guide rollers are only set on the long axis, which will affect the cutting quality of glass fibers. Contents of the invention [0003] The object of the present invention is to provide a glass fiber cutting device with simple structure and convenient operation, so as to solve the problems raised in the above-...
