Abstract

The utility model relates to a shearing device, in particular to a fiber cutter. The fiber cutter comprises a cutter seat, a cutter holder, a cutter holder right-angle positioning shaft, a shear knife and a shearing bed, wherein the cutter holder right-angle positioning shaft is arranged on the cutter seat and movably connected with the cutter holder; and the fiber cutter is characterized in that the shear knife is fixed on the cutter holder, and a shearing through hole at the center of the shearing bed is matched with the knife head part of the shearing knife. The fiber cutter can ensure two cutting surfaces of the shorn fiber sections to be neat, and does not cause squeezing or stretching. Moreover, fiber bundles can be shorn into fiber sections of fixed length. A guiding bulge is arranged at the knife head part of the shear knife, thus preventing the shear knife and the shearing bed from shifting in shearing process, leading the knife edges and the shearing bed to be matched accurately, and prolonging the service life of the shear knife and the shearing bed.

Description

Fibre cutter

Technical field

The utility model relates to a kind of shear, relates in particular to a kind of fibre cutter.

Background technology

Before the fiber to all kinds of textile materials such as cotton, fiber crops, hair, silk, chemical fibres carries out cloth specimen, need equably segment of fiber to be cut into suitable length.But fibre cutter in the market, its structure and principle and general paper knife are similar, and the segment of fiber length of shearing out is inhomogeneous, and the wearing and tearing easily of cutter head part, and service life is short.

Summary of the invention

The purpose of this utility model provides a kind of segment of fiber that can shear out even length, and long service life, the nonabradable fibre cutter of cutter head part.

The utility model is achieved in that fibre cutter, is made of tool rest, handle of a knife, handle of a knife right angle locating shaft, shear knife and Cut Block; Described handle of a knife right angle locating shaft places on the tool rest, and flexibly connects with handle of a knife; It is characterized in that: described shear knife is fixed on the handle of a knife, and the thickness of its cutter head part is H; Described Cut Block is positioned on the tool rest, and the shearing through hole at Cut Block center and the cutter head of shear knife partly match.

The cutter head of described shear knife partly is provided with guide protrusion.

The scope of the thickness H of described shear knife cutter head part is 0.8-1.8mm.

On the described tool rest, the below of handle of a knife is provided with a packing ring.

Described tool rest has at least two feets.

The utility model beneficial effect is: utilize the cutter head both sides of shear knife to cooperate the shearing force that produces with the shearing through hole both sides at Cut Block center, can guarantee that two fractures of the segment of fiber sheared are neat, do not have extruding, not have and stretch.Simultaneously, because the edge of a knife of shear knife has certain width, can smoothly, fiber beam cutting not become the segment of fiber of fixed length with having stretching.The utility model partly is provided with a guide protrusion at the shear knife cutter head, thereby prevents that shear knife and Cut Block are subjected to displacement in shear history, makes the edge of a knife and tool rest cooperate accurately, and shear knife and Cut Block are when cut-in without ball, and its edge of a knife does not does not wear and tear yet, not bias; Thereby prolonged the service life of shear knife and Cut Block.

Specific embodiment

Below in conjunction with drawings and Examples the utility model is elaborated:

Fibre cutter of the present utility model is to be made of tool rest 1, handle of a knife 2, handle of a knife right angle locating shaft 3, shear knife 4 and Cut Block 5.Described handle of a knife right angle locating shaft 3 places on the tool rest 1, and flexibly connects by a screw and handle of a knife 2, and handle of a knife 2 can be up and down in 90 degree scopes thus.Shear knife 4 of the present utility model is fixed on the handle of a knife 2 by screw, and the scope that its cutter head segment thickness is H is 0.8-1.8mm, can guarantee that thus the length of the segment of fiber sheared out is even, and be easy to cloth specimen.And described Cut Block 5 is positioned on the tool rest 1, and the cutter head of the shearing through hole 51 at Cut Block 5 centers and shear knife 4 partly matches; Press down handle of a knife 2, the cutter head part of shear knife 4 is embedded into fully to be sheared in the through hole 51, then the generation shearing force matches with two limits of shearing through hole 51 in the cutter head both sides of shear knife 4, this shearing force can will place the fibre bundle one on the Cut Block 5 to be divided into three, and middle segment of fiber falls from the shearing through hole 51 of Cut Block 5.

Be subjected to displacement when shearing in order to prevent that shear knife 4 from matching with Cut Block 5, the utility model partly is provided with guide protrusion 41 at the cutter head of described shear knife 4.Like this, when shear knife 4 pressed down, the guide protrusion 41 of its cutter head part was embedded into earlier in the shearing through hole 51 of Cut Block 5, thereby had played the effect of an orientation direction, made shear knife 4 and Cut Block 5 accurately to cooperate.

For preventing that handle of a knife 2 from pressing down wearing and tearing tool rest 1, the utility model is on described tool rest 1, and the below of handle of a knife 2 is provided with a packing ring 6.Simultaneously, the utility model has at least two feets 7 at described tool rest 1, places thereby reserve enough spaces, is used to accept to be sheared the container of the segment of fiber of getting off.

Operating process of the present utility model is as follows:

At first, a container that cleans is placed into tool rest 1 time, its opening is over against the shearing through hole 51 of Cut Block 5.One fibre bundle laterally is placed on the Cut Block 5, presses down shear knife 4 then and make its cutter head part be embedded into fully in the shearing through hole 51 of Cut Block 5; Fibre bundle is sheared into three sections owing to be subjected to the shearing force of shear knife both sides, middle one section along with the pressing down of shear knife 4, pass and shear through hole 51 and drop in the container of tool rest 1.Segment of fiber in the container can be placed into then and carry out cloth specimen in the fiber distributor.
