Background
The computerized flat knitting machine is operated by the knitting needles to perform regular lifting motions, so as to realize the actions of yarn backing, closing, loop, slashing, loop forming and the like, thereby completing the knitting of the fabric. In the process of raising the knitting needle, the loop gradually withdraws from the needle hook, opens the needle tongue, and withdraws from the needle tongue to be hung on the needle bar; in the process of descending the knitting needles, the needle hooks hook the newly laid yarn and pull and bend the yarn into loops, meanwhile, the original loops are separated from the needle hooks, the new loops pass through the old loops and are connected with the old loops in series, and a plurality of loops formed by knitting a plurality of knitting needles are connected with each other, so that the knitting of the fabric is finally completed.
Because the machine head frequently drives the cam system to slide left and right in the knitting process, the stitch of the spring needle below the knitting needle which does not participate in the knitting work is always tightly attached to the non-knitting sheet, and after long-time sliding friction contact, abrasion is generated between the stitch and the non-knitting sheet, so that the preset height between the stitch becomes low, the phenomenon of firing pin or needle selection error frequently occurs when the machine head drives the cam system to slide left and right, the failure rate of the computerized flat knitting machine in the working process is increased, the maintenance and maintenance cost is improved, and the working hours are prolonged.
In addition, in the sliding friction process of the knitting needles which do not participate in knitting and the non-woven pressing sheet, the stitch on the spring needle below the knitting needles is tightly pressed on the non-woven pressing sheet by means of self elastic force, when the number of the knitting needles which do not participate in knitting is large, the elastic pushing force combined together is very large, after the elastic pushing force is applied to the machine head, the load of the machine head is additionally increased, and the machine head becomes very heavy when walking left and right.
Therefore, the applicant applies for a Chinese patent application number 2023105993289, named as a novel computerized flat knitting machine mountain plate and a crochet machine, on the premise of meeting the action of the existing fabric in the process of knitting the fabric, the utility model fully reduces the failure rate in working, lightens the load of the machine head in working, simplifies the whole structure, greatly saves the production and manufacturing cost, and effectively solves the technical problems.
Later, the applicant carries out new structural design on the product of the patent application of the utility model in the actual production process so as to further effectively save the production and manufacturing cost, thereby additionally applying for an utility model patent.
