Problems solved by technology

[0002] At present, in computerized flat knitting machines, because the position of the yarn feeder is far away from the knitting area, there is a certain distance between the floating thread and the needle hook. During knitting, it is easy for the knitting needle to hook the thread unstable or even the needle cannot hook the yarn. , affecting fabric quality and reducing production efficiency

Embodiment 1

[0024] see figure 1 , figure 2 , the present embodiment provides a crimping device for a flat knitting machine, which is installed on the triangular carriage of the flat knitting machine, including a bracket 1, a brush seat 4 and a brush 5, and the bracket 1 is fixed on the triangular carriage ; The brush 5 is fixed on the brush seat 4 by a brush clip, and the brush 5 is a replaceable part to reduce costs; the brush seat 4 is connected to the support 1 movable relative to the support 1 , the bracket 1 is equipped with an actuator that can drive the brush seat to move up and down. When the needle hook of the flat knitting machine needs to hook the thread, the actuator drives the brush seat 4 to move down. At this time, the brush 5 presses down the yarn. When the needle hook of the flat knitting machine does not need to hook the thread, the actuator drives the brush seat 4 to move upwards, and the brush 5 resets now. In the present invention, by installing a pressing device o...

Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is that the actuator described in this embodiment is an electromagnet, the electromagnet is fixed on the bracket 1, and the electromagnet is connected to the brush holder 4 by adsorption. When the power is turned on, the brush holder 4 moves up and resets under the action of the electromagnet, and when the electromagnet is powered off, the brush holder 4 moves down under its own weight or elastic structure. When the knitting needle enters the knitting area, according to the needs of knitting, the brush 5 is controlled to move up and down. When the needle hook needs to hook the thread, the electromagnet is powered off, and the brush seat 4 moves down to drive the brush 5 to move down to lower the yarn to ensure The knitting needle hooks the yarn smoothly; when the needle hook does not need to hook the thread, the electromagnet is powered on, the electromagnet picks up the brush holder 4, and resets to drive the brush...

Abstract

The invention discloses a yarn pressing device of a flat knitting machine. The yarn pressing device is mounted on a carriage and comprises a support, a brush base and a brush, the brush is fixed to the brush base, and the brush base can be movably connected with the support relative to support; an executing part which can drive the brush base to move up and down is mounted on the support, when a hook of a flat knitting machine needs to conduct hooking, the executing part drives the brush base to move down, and at this moment, the brush depresses yarn; when the hook of the flat knitting machinedoes not need to conduct hooking, the executing part drives the brush base to move up, and at this moment, the brush resets. The yarn pressing device is additionally arranged on the carriage of the flat knitting machine and controls the brush to move up and down according to knitting requirements, when the hook needs to conduct hooking, the executing part drives the brush to move down to depressthe yarn, and thus it is guaranteed that a knitting needle successfully hooks the yarn; when the hook does not need to conduct hooking, the executing part resets and drives the brush to exit a workingposition. By cooperating with the yarn pressing movement, the yarn pressing machine can make the knitting needle hook the yarn, the hooking stability is improved, and thus the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of knitting machinery, and in particular relates to a thread pressing device of a flat knitting machine. Background technique [0002] At present, in computerized flat knitting machines, because the position of the yarn feeder is far away from the knitting area, there is a certain distance between the floating thread and the needle hook. During knitting, it is easy for the knitting needle to hook the thread unstable or even the needle cannot hook the yarn. , affecting fabric quality and reducing production efficiency. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a crimping device for a flat knitting machine that improves production efficiency and ensures stable thread hooking. [0004] The technical scheme adopted in the present invention is: [0005] A crimping device for a flat knitting machine, which is installed on the trian...
