Loop transfer needles capable of being automatically restored and loop transfer mechanism with loop transfer needles

Abstract

The invention relates to loop transfer needles capable of being automatically restored and a loop transfer mechanism with the loop transfer needles. Each loop transfer needle comprises a needle body,one side of each needle body is provided with needle selection butts and a limiting groove, and a restoring spring piece is connected to the other side of each needle body; each needle body is dividedinto a rear part, a middle part and a front part; the needle selection butts are located at the rear parts of the needle bodies; the limiting grooves are located in the portions, close to the front parts, of the middle parts of the needle bodies, and when the loop transfer needles move forwards to the extreme position along needle grooves, limiting steel wires installed on loop transfer needle beds are clamped in the limiting grooves. The loop transfer mechanism comprises the loop transfer needle beds, loop transfer needle boards and the loop transfer needles. According to the loop transfer needles capable of being automatically restored and the loop transfer mechanism with the loop transfer needles, through the cooperation of the limiting grooves and the limiting steel wires, the loop transfer needles can be prevented from sliding out of the loop transfer needle beds, and the working reliability of the loop transfer needles is guaranteed; the restoring spring pieces replace restoringcams, the corresponding installing structure of the restoring cams is reduced, and the loop transfer mechanism can be simplified as a whole, so that the whole loop transfer mechanism is miniaturizedand compacted. A two-stage needle selection device is adopted as the needle selection device, random needle selection can be achieved, and the needle selection precision is high.

Description

technical field [0001] The invention relates to the field of knitting flat knitting machines, in particular to a loop transfer needle capable of automatic reset and a loop transfer mechanism with the loop transfer needle. Background technique [0002] When knitting knitted fabrics, because of the needs of the pattern, the coils often need to be transferred alternately on the two needle beds, and in order to transfer the coils between the two needle beds, there must be empty needles on the other needle bed, so usually on the two needle beds The transfer needle is arranged above the needle bed to temporarily catch the loop, thereby assisting the knitting needle to complete the normal knitting process. [0003] The existing loop transfer needles are usually provided with a selection heel and a reset needle butt. When participating in knitting, the needle selection heel is exposed from the loop transfer needle bed, so that it can move forward or backward under the drive of the l...

Problems solved by technology

[0003] The existing loop transfer needles are usually provided with a selection heel and a reset needle butt. When participating in knitting, the needle selection heel is exposed from the loop transfer needle bed, so that it can move forward or backward under the drive of the loop transfer mountain plate. The loop-transfer needles involved in knitting are selected by the needle selector, and the loop-transfer needles are pressed into the loop-transfer needle bed. When the loop-transfer needles pressed into the needle bed need to be reset, the reset triangle usually needs to be used. Setting the reset triangle increases the The complexity of the entire loop transfer mechanism, for a precision machine such as a flat knitting machine, the higher the complexity, the more prone to failure, so it is necessary to improve and optimize the existing loop transfer needle and the loop transfer mechanism
