Description

Comb device on no waste yarn

Technical Field

The utility model relates to a weaving equipment technical field, concretely relates to comb device on no waste yarn.

Background

A flat knitting machine needs to complete the knitting of a complete knitted piece, and generally, the complete knitted piece mainly comprises a starting waste yarn, a stitch removing, an upper comb, a cylinder (idle rotation), ribs, a big body and the like; the drawing-out process of the knitted fabric after the knitting is to apply certain traction force to the formed knitted fabric to draw the formed knitted fabric out of the knitting area. Because a certain distance exists between the needle bed opening and the traction device in the flat knitting machine, namely, the knitted fabric cannot be clamped by the traction device immediately when being knitted, if the normal knitting of the knitted fabric piece is directly carried out, the knitted fabric piece just knitted (namely, the knitted fabric piece which is not clamped by the high-position roller) floats upwards due to lack of uniform traction force, so that the knitted fabric piece is uneven, and the whole knitting effect of the knitted fabric piece is influenced; that is, the weaving of the fabric piece can be smoothly performed only in a pulled state. It is therefore necessary to knit the carding transition fabric before entering the formal knit fabric. The flat knitting machine equipped with a plate-setting device on a crochet needle uses elastic yarn to knit rib knitting head.

The flat knitting machine without the combing device needs to comb the transitional fabric with the weaving length of about 25-35mm, and after the transitional fabric is clamped by a high-position roller below a needle bed opening, a weaving piece can obtain certain traction force and then enter formal weaving. Therefore, each piece of knitted fabric needs to be knitted into a transition fabric with the thickness of 10-35mm for transition, and after the piece of knitted fabric is knitted, workers need to detach the transition fabric (waste yarn) on the piece of knitted fabric. Therefore, the conventional flat knitting machine needs to realize the integral knitting of the knitted fabric piece by waste yarn before starting knitting, so that the integral working efficiency is reduced, and the yarn is wasted.

The other carding mode of the hand-operated flat knitting machine is to utilize the main yarn upper carding tissue of the knitted piece to hand-knit one line of upper carding yarn, then the needle teeth of the threading plate are manually penetrated into the knitting hook to be hung on the upper carding coil rows of the front needle bed and the rear needle bed, a steel wire is manually penetrated and blocked, the upper carding is drawn before the next line of cylinder tissue is not knitted, a heavy object is hung below the threading plate to draw the knitted piece, and then the cylinder, the rib, the big body and the like are continuously hand-knitted. Although the method does not use waste yarn for carding, the knitted piece has loose, untight, non-smooth and non-beautiful starting opening, and can not meet the quality requirement of the current knitted piece.

Based on the above technical problems, the current situation is as follows: most manufacturers and users of the flat knitting machine are not practical for the carding of the knitted fabric by the carding method of the carding device, or continue to use the waste yarn traction method for the carding of the knitted fabric, and the effective scheme for designing and optimizing the carding device of the flat knitting machine is lacked in the industry.
