Control mechanism of yarns-transfer

Abstract

The invention relates to a control mechanism which changes yarns. The control mechanism which changes yarns is arranged on a circular knitting machine; when operating, the control mechanism is controlled by a pushing orbit and a needle selector to lead knitting cloth to obtain different secondary color effects. The control mechanism which changes yarns is formed by the method that a doffing piecein a weft selecting control part is provided with a socket and a capacity slot is arranged at a driving piece; an upper positioning snug and a lower positioning snug of a swing piece are respectivelyconnected with the socket and the capacity slot to lead that when in movement, a web selection jack realizes precision contraposition to reduce the friction drag and prolong the service life of the web selection jack; and the bottom end of a lifting board in a coupling part is provide with a socket, while the snug which is arranged at one end of the coupling bar is arranged in the socket, and thedesign of coupling type at the two sides is adopted so that when the lifting board drives the schlagblech to do the operation of changing yarns, the mechanism saves labor, and the operation is smooth, thus not leading to the motion beat owing to timeliness abrasion. The mechanism is provided with a trip piece on an upper end device part which is matched with an elastic piece and can be rapidly fixed on or breaks away a fixed seat of the stander so that the dismounting and mounting of the mechanism is more rapid and easier.

Description

technical field [0001] The invention relates to a control mechanism for changing yarns. Background technique [0002] When the known knitting machine (circular knitting machine) weaves cloth, if the cloth needs to be knitted with patterns of different colors, a control mechanism or a color-changing head for changing yarns will be installed at the yarn feeding port of the knitting machine. During the process, the mechanism will timely bring the colored yarn to the yarn feeding port for the knitting needle to hook the yarn, so that the colored yarn is woven together, so that the woven fabric has a second-color pattern effect. In order to achieve the above effect, the mechanism The design of the knitting machine is relatively complicated.

[0002] When the known knitting machine (circular knitting machine) weaves cloth, if the cloth needs to be knitted with patterns of different colors, a control mechanism or a color-changing head for changing yarns will be installed at the yarn feeding port of the knitting machine. During the process, the mechanism will timely bring the colored yarn to the yarn feeding port for the knitting needle to hook the yarn, so that the colored yarn is woven together, so that the woven fabric has a second-color pattern effect. In order to achieve the above effect, the mechanism The design of the knitting machine is relatively complicated. Compared with the known yarn-changing control mechanism or color-changing head, the combination and interlocking mode of the internal parts mostly adopts an open interlocking design. Although this method is relatively simple, it needs to be In high-speed operation and fast movement, the cooperation and linkage of each part must be very precise and precise, and the control is not easy. Therefore, it is often difficult to move due to a slight error in the cooperation between the parts or due to time-related wear and tear. And it will cause malfunction, which will lead to the error of changing the color of the yarn, causing serious losses to the industry, which is very unsatisfactory.
