Walk-needle control mechanism of computer transversal knitting machine

Abstract

The invention relates to a walk-needle control mechanism of a computer transversal knitting machine, provided with a needle bed and a plurality of needle slots transversally arranged on the needle bed. Each needle slot is internally provided with a knitting needle component and a triangular soleplate, wherein the knitting needle component can longitudinally move; the triangular soleplate is arranged above the needle bed and matched with the knitting needle component; each knitting needle component comprises a knitting needle, a needle-pushing sheet and a needle-selecting sheet which are sequentially arranged; the triangular soleplate is provided with a needle selector; a needle heel is arranged at the lower part of the knitting needle; the triangular soleplate is provided with a knitting needle control component, a needle-pushing control component and a needle-selecting control component; the knitting needle control component controls the moving track of the knitting needle; the needle-pushing control component controls the moving track of the needle-pushing sheet; and the needle-selecting control component controls the moving track of the needle-selecting sheet. The walk-needle control mechanism of the computer transversal knitting machine can singly control the movement of the knitting needle, the needle-pushing sheet and the needle-selecting sheet, radically solves the problems of overlong motion distances of the needle-pushing sheet and the needle-selecting sheet, lessens the unnecessary abrasion of the needle-selecting sheet and the needle-pushing sheet, effectively prolongs the service life, simplifies the control problem of the triangular soleplate and has stronger walk-needle track controllability, high working stability and reasonable design.

Description

technical field [0001] The invention relates to a computerized flat knitting machine, in particular to a needle movement control mechanism of the computerized flat knitting machine. Background technique [0002] Computerized flat knitting machine is currently the most commonly used processing equipment for sweater manufacturers. Computerized flat knitting machine can be divided into semi-automatic looms and fully automatic looms. Semi-automatic looms can be equipped with hand-operated flat knitting machines to realize automatic needle placement. The function reduces the labor intensity of the operator to a certain extent. However, in the process of weaving products, there are a lot of narrowing besides the needle setting, and the narrowing of the semi-automatic loom is still done by a large number of manual operations. Therefore, , automatic weaving cannot be realized, so that the weaving efficiency cannot be really improved; the needle movement control of the automatic loom...

[0002] Computerized flat knitting machine is currently the most commonly used processing equipment for sweater manufacturers. Computerized flat knitting machine can be divided into semi-automatic looms and fully automatic looms. Semi-automatic looms can be equipped with hand-operated flat knitting machines to realize automatic needle placement. The function reduces the labor intensity of the operator to a certain extent. However, in the process of weaving products, there are a lot of narrowing besides the needle setting, and the narrowing of the semi-automatic loom is still done by a large number of manual operations. Therefore, , automatic weaving cannot be realized, so that the weaving efficiency cannot be really improved; the needle movement control of the automatic loom is guided by the needle movement track of the triangular bottom plate and the cooperation of the knitting needle components, and the automatic control of the weaving machine is realized through computer program control; The knitting needle assembly of the current automatic loom generally includes several knitting needles and needle selectors. Each needle selector corresponds to a knitting needle as a group and is arranged in a needle groove of the needle bed. Through the needle selector, select whether the selector is working or not. Once the selector is selected to work, the selector will move up and down according to the track of the triangular bottom plate, and at the same time push the knitting needle to the set position, and then the knitting needle will Move up and down according to the triangular bottom plate circuit to complete different tasks such as knitting, tucking, transfer, and connecting rings. However, since the knitting needle assembly in the prior art only has knitting needles and needle selectors, the walking of the needle selectors The longer track line increases the probability of failure; although there are also knitting components composed of three parts: knitting needles, pusher jacks, and needle selection jacks, such as a computerized flat knitting machine with knitting and transfer systems disclosed in Chinese patent 200810196755.8 The triangle mechanism of the knitting machine, and the knitting assembly disclosed in the knitting needle assembly of a computerized flat knitting machine disclosed in Chinese patent 200820034322. Joint-like cooperation is adopted between the pieces, and the movement of the knitting needle is completely controlled by the pusher piece, so in fact, the movement of the knitting needle is transferred to the pusher piece for control, and due to knitting, tucking, transfer, and connection Different tasks such as ringing are completed by the two parts of the pusher and the selector. The walking route of the selector and the pusher has not changed, and the stroke is still long, so the relative wear of the selector and the pusher is relatively serious. , the controllability of the needle trajectory is also poor, and since the needle movement line is only controlled by the two parts of the needle selector and the pusher, it can only be controlled by a more complicated triangular bottom plate, which increases the complexity and complexity of the triangular bottom plate.
