Description

Staple-fibre cutting machine

The utility model belongs to a kind of chopping equipment, particularly a kind of fiber chopping machine that cuts various fibre bundles.

In the production and processing of glass fiber reinforced plastics product, usually need the precursor of rolling is cut into the short silk of certain-length sometimes, be blended in the fiberglass raw material as aggregate, to improve the intensity of glass fiber reinforced plastics product.The chopping machine of the various fibre bundles of existing cutting is reciprocating type chopping machine, it is mainly by frame, the transmission slewing equipment, wire feeder, knife rest, and on, lower cutter is formed, lower cutter is fixed on the frame, upper cutter is fixed on the knife rest, knife rest is connected with the transmission slewing equipment, doing under the drive of transmission slewing equipment, following reciprocating motion, upper cutter is last, tangent in the process of following motion with lower cutter, precursor is cut into the short silk of certain-length, reciprocating motion of the every do of the upper cutter of this chopping machine, just can finish once cutting, therefore, its production efficiency is very low, per hour chopping only is about 5 kilograms, is difficult to adapt to the actual needs of producing; In addition, this machine is to cut tow by the mutual shearing of upper and lower cutting knife, therefore, gap between the upper and lower cutting knife is most important, the gap is too small can damage cutting knife, excesssive gap then can't cut tow, particularly when the glass-cutting tow, because glass filament bundle is harder, in cutting process, cutting knife is quick-wearing very, and the gap between cutting blade abrasion or the upper and lower cutting knife not only can not cut when improper, also tow can be clipped between the upper and lower cutting knife, occur wired or cut continuous problem, what influence was produced normally carries out.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, provide a kind of fault few, not wired, can cut continuously, fiber chopping machine that production efficiency is high.

The utility model is achieved in that

It has a frame that is welded into angle steel and steel plate, and the transmission device of being made up of motor and driving belt is installed in frame; Two supporting side plates are installed on frame, a rotor and a rubber roll that matches with rotor that has several blades is installed on supporting side plate, described rotor links to each other with transmission device, and rubber roll rotates when rotor rotates thereupon; A pressure roller that matches with rubber roll also is installed on supporting side plate, and rotates, thereby fibre bundle is sent between rotor and the rubber roll with rubber roll, along with the rotation of rotor with its cut-out.

The utility model compared with prior art has following advantage:

1, the utility model adopts rotor to come the cutting fiber tow, when rotor rotates, and continuable the cutting; The linear velocity of rotor cutting is 140 meters/minute～190 meters/minute, and can cut 5 strands of precursor simultaneously, and output can reach 190 kilograms/hour～230 kilograms/hour, and production efficiency increases substantially; The spacing of corresponding adjusting blade and quantity also can cut out the short silk of 5～50 millimeters different length.

2, adopt rubber roll to match with rotor, during cutting, the wearing and tearing of blade are little, can not occur wired and the continuous problem of cutting.
