Controller for yarn changer

Abstract

The invention relates to a knitting machine and particularly relates to a controller for a yarn changer. The controller comprises a controller skeleton arranged on an outer plate of a yarn changer main body, a transfer bar, a digital circuit and a drive mechanism for driving the transfer bar to carry out linear motion, wherein the transfer bar is connected with the controller skeleton in a sliding manner; the transfer bar drives a yarn clamping and shearing device of the yarn changer to complete yarn selecting and yarn guiding actions while carrying out linear motion; the digital circuit and the drive mechanism are arranged on the controller skeleton separately; and the digital circuit is electrically connected with a drive mechanism. External drive is not needed, and the drive mechanism can be controlled to drive the transfer bar to carry out linear motion by virtue of the digital circuit, so that the transfer bar drives the yarn clamping and shearing device to complete the yarn selecting and yarn guiding actions, and independent control on yarn selecting and yarn guiding of the yarn changer is achieved; and the controller is small in impact vibration, high in applicability, stable in working, simple in structure and beneficial to improvement of the production stability of the knitting machine.

Description

technical field [0001] The invention relates to a knitting machine, in particular to a controller used on a thread changer. Background technique [0002] The thread changer is used for circular knitting machines. Each thread changer installed in the circular machine is equipped with several colored yarns. During the weaving process, the thread changer makes the colored yarns participate in the weaving according to the requirements of the knitting process, and weaves multi-color horizontal For a piece of fabric, the controller of the existing thread changer drives the internal yarn selection knife to swing after receiving the system signal, and selects the yarns involved in weaving. After selection, it needs to cooperate with the triangle of the knitting machine to drive the push-pull rod of the thread changer The clamping and cutting yarn driven by the thread changer leads the yarns participating in the weaving to the weaving area. In actual use, there are usually large shoc...

[0002] The thread changer is used for circular knitting machines. Each thread changer installed in the circular machine is equipped with several colored yarns. During the weaving process, the thread changer makes the colored yarns participate in the weaving according to the requirements of the knitting process, and weaves multi-color horizontal For a piece of fabric, the controller of the existing thread changer drives the internal yarn selection knife to swing after receiving the system signal, and selects the yarns involved in weaving. After selection, it needs to cooperate with the triangle of the knitting machine to drive the push-pull rod of the thread changer The clamping and cutting yarn driven by the thread changer leads the yarns participating in the weaving to the weaving area. In actual use, there are usually large shocks and vibrations, it is difficult to install and debug the push-pull rod of the thread changer and the triangle of the knitting machine, and the controller is unstable. In some cases, it is easy to cause control errors and affect production, and the structure is complicated, and it is impossible to realize the independent control of yarn selection and yarn introduction of the thread changer
