Bottom rising device of knitting horizontal machine

Abstract

The invention relates to a lifting device of a flat knitting machine, which comprises a lifting plate, a driving device and a starting needle. The starting needle is installed on the lifting plate and driven by the driving device to move. Composed of rods, the yarn withdrawal rod is a slender sheet, and the crochet needle has a transparent groove in its longitudinal direction, which is matched with the yarn withdrawal rod. The yarn withdrawal rod is placed in the longitudinal groove of the hook needle and can slide up and down in the groove. The lower end of the crochet needle has a joint that fixes it on the bottom plate, and the lower end of the yarn withdrawal rod has a joint that fixes it with the yarn withdrawal lifting device; the hook and the yarn withdrawal rod have notches in the same direction at their front ends, The notch is composed of at least two surfaces; the surface near the notch at the top of the crochet hook is in the shape of an upward slope; and the surface near the notch at the top of the yarn withdrawal rod is hook-shaped; it has a simple structure, is easy to install, and reduces the number of threads Waste, improve work efficiency.

Description

technical field [0001] The invention belongs to the technical field of flat knitting machines, in particular to a bottoming device of a flat knitting machine. Background technique [0002] The flat knitting machine can complete the knitting of a complete garment piece. Generally, a complete garment piece is mainly composed of waste yarn, thread removal, bottoming, idling, rib, body and other parts; The pulling output process is to pull the formed knitted fabric out of the loop forming area, give the fabric a certain tension and then send it out. The pulling has a great influence on the loop forming process and product quality, and the following basic requirements should be met: due to the loop forming The process is continuous, and the pulling movement should be required to run continuously; the pulling tension acting on each coil should be stable, uniform, and consistent; and the pulling tension, the pulling amount per unit time and the loop forming process need Simultaneo...

[0002] The flat knitting machine can complete the knitting of a complete garment piece. Generally, a complete garment piece is mainly composed of waste yarn, thread removal, bottoming, idling, rib, body and other parts; The pulling output process is to pull the formed knitted fabric out of the loop forming area, give the fabric a certain tension and then send it out. The pulling has a great influence on the loop forming process and product quality, and the following basic requirements should be met: due to the loop forming The process is continuous, and the pulling movement should be required to run continuously; the pulling tension acting on each coil should be stable, uniform, and consistent; and the pulling tension, the pulling amount per unit time and the loop forming process need Simultaneously, because there is a certain distance between the mouth of the needle bed and the pulling device in the flat knitting machine, that is to say, it is impossible for the garment parts to be clamped by the pulling device immediately when they are woven. In normal weaving, the newly woven pieces (ie, the pieces not held by the rollers) are uneven due to lack of uniform pulling force, which affects the overall weaving effect of the pieces; in addition, when the machine needs to continuously knit V For garments such as collars or round necks, because the initial width of the garments is different, it is necessary to re-weave the waste yarn before weaving the next garment. It can be seen that the waste yarn must be used to realize the weaving of the garment before weaving. Integral weaving, which not only reduces the overall work efficiency, but also greatly wastes the use of yarn
