Problems solved by technology

like figure 1 As shown, the overall size of the scissor blades (1) of all models of the automatic shearing and turning-up towel machine commonly used at home and abroad is unreasonable, and it forms a thick "wall" together with the lower raw gram sheet (2).
It blocks the compressed air ejected from the dedusting nozzle (3) from penetrating through the gap in the "wall" in a limited space while it moves with the lower gram sheet (2) to generate a shearing effect, thereby The lint that adheres to its gap cannot be removed
The remaining cotton dust will in turn affect the cutting edge of the scissors, leading to unfavorable shearing, thus forming a vicious circle, which will greatly shorten the service life of the scissors and cause unstable cloth quality

Embodiment 1

[0011] Such as figure 1 , figure 2 As shown, the scissors device of the turned-up towel machine is installed on the automatic shearing and turned-up towel machine, and consists of a scissors 1 and a lower raw gram 2 tangent to the scissors 1. The scissors 1 are arranged in the syringe 11 On the upper part, it is fixed on the gram triangle 12 and can move left and right. The gram triangle 12 is provided with an upper cutting block 13, and the lower gram piece 2 is arranged on the inner side of the dial 21, and is overlapped with the scissors 1. It can move up and down, and the top right of the scissors blade 1 is provided with a gap 16 . The present invention adopts a new type of shape for the scissors of all machine sizes of the automatic hair-shearing and turning-up towel machine, and removes the material of the non-working position of the scissors as much as possible without affecting the working strength of the scissors. That is: a larger gap of the same size is dug out ...

Embodiment 2

[0013] Such as figure 2 As shown, the scissors device of the turned-up towel machine is installed on the automatic shearing and turned-up towel machine, and consists of a scissors 1 and a lower raw gram 2 tangent to the scissors 1. The scissors 1 are arranged in the syringe 11 On the upper part, it is fixed on the gram triangle 12 and can move left and right. The gram triangle 12 is provided with an upper cutting block 13, and the lower gram piece 2 is arranged on the inner side of the dial 21, and is overlapped with the scissors 1. Can move up and down, the top right of the scissor blade 1 is provided with a gap 16, in order to increase the air pressure, the gap 16 is provided with a dust removal nozzle 3, and the dust removal nozzle 3 faces the shearing place. The pressure of the air is strong, and it is easier to remove cotton waste. The notch 16 is at right angles, and the corners are arc transitioned. The lower right-angled side of the notch 16 is on the same level as th...

Abstract

The invention relates to the field of circular knitting machines, in particular to a shear blade device for an automatic shearing velour knitting machine, which is arranged on the automatic shearing velour knitting machine. The shear blade device comprises a shear blade, and a lower sinker tangent to the shear blade, wherein the shear blade is arranged on a needle cylinder, is clamped on a sinker triangle, and can move leftwards and rightwards; the sinker triangle is provided with an upper shearing block; the lower sinker is arranged on the inner side of a needle disk, is overlaid with the shear blade, and can be moved up and down; a notch is formed on the upper right side of the shear blade; the notch is provided with a dedusting air tap; and the dedusting air tap faces a shearing point. Sprayed compressed air removes cotton flocks when the shear blade device is operated; the notch has a right angle, and the corner has circular transition; the lower right-angle side of the notch and the upper end of the sinker triangle are on the same plane; and ventilating regions can be increased maximumly. Due to the structure, soft flocks adhered to the blade can be easily removed, a traditional fixed thinking model that the shape of the shear blade cannot be changed is broken, the shape of the shear blade is skillfully modified, and a series of defects are overcome to a great extent.

Description

technical field [0001] The invention relates to the field of circular knitting machines, in particular to a scissor blade device for an automatic shearing and turning-up towel machine. Background technique [0002] At present, the automatic shearing and turning-up towel machine is still a relatively high-end product in China. Its key technology is: a whole set of scissors is installed, which can cut every hair on each cloth surface while completing the weaving process of turning-up toweling. The circle is neatly cut. However, there is a serious defect in domestic and even domestic products in the world at present, that is: each set of scissors also produces a large amount of cotton dust when cutting the loops, and it is extremely difficult to be cleaned. Such as figure 1 As shown, the overall size of the scissor blades (1) of all models of the automatic shearing and turning-up towel machine commonly used at home and abroad is unreasonable, and it forms a thick "wall" toget...
