Description

Driving structure for switching left needle and right needle of one-groove double-needle plate

Technical Field

The utility model relates to the technical field of knitting of computerized flat knitting machines, in particular to a driving structure for switching left and right needles of a one-groove double-needle plate.

Background

It is known that knitting needle assemblies in computerized flat knitting machines are typically mounted within needle grooves of a needle plate, which are defined by adjacent blades inserted into the needle plate. When the computerized flat knitting machine works, the knitting needle component is driven by the triangular mechanism to continuously stretch and retract along the needle groove, so that the knitting work of the fabric is completed.

For a general knitted fabric, the denser the knitting, the better. Therefore, most manufacturers at present begin to reduce the distance between two adjacent inserting sheets by increasing the number of inserting sheet grooves per inch along the length direction (transverse direction) of the needle plate, so as to achieve the purpose of reducing the needle pitch (the distance between two adjacent knitting needles), or further, a containing groove is formed on the side wall of the inserting sheet corresponding to the knitting needles, and a part of the width of the knitting needles is hidden in the containing groove to increase the number of knitting needle assemblies per inch as much as possible.

For example, patent number ZL 202123446064.9, named "computerized flat knitting machine ultra-dense needle inserting sheet combined structure" is that symmetrical abdication grooves are milled on two side walls of the front part of the inserting sheet respectively, and a part of the width of the knitting needles is contained by the abdication grooves, so that the number of the knitting needles per inch on a needle plate is increased, and the aim of shortening the needle pitch is achieved.

For example, in the chinese patent No. ZL2022217977216, entitled "improved structure of needle insertion sheet of computerized flat knitting machine", the product of this patent is that two elongated slots are formed along the upper side wall of the insertion sheet, so that the difficulty in milling or grinding can be sufficiently reduced during the production and processing of the insertion sheet, the overall manufacturing accuracy of the insertion sheet can be effectively ensured, and the final purpose is to provide enough space for additionally adding knitting needle assemblies.

Although the number of knitting needles per inch is increased by the continuous innovation of the technology of some existing manufacturers, the number of knitting needles per inch is limited by the prior art, and can only reach 32 at most, so the number is the industry limit, and the increase of the number of knitting needles per inch is generally at the cost of sacrificing the thickness of the inserting sheet and the knitting needle assembly, and the thickness of the inserting sheet and the knitting needle assembly is known to be thinner, so that the workability of knitting of the knitting needles is affected directly, and therefore, the method is one of technical problems which are urgent to be solved by the technicians in the field.
