A fully automatic computerized jacquard machine color changing mechanism

Abstract

The invention provides a color change mechanism of a full-automatic computer jacquard machine. The color change mechanism comprises a base, a needle rod frame fixed to the base and a plurality of needle rods uniformly fixed to the needle rod frame in rows, wherein a moving mechanism for controlling the needle rod frame to stepwise move in a needle rod arrangement direction is arranged on one side of the upper part of the needle rod frame; an up-down driving mechanism for driving the needle rods to move up and down is arranged on one side, close to the needle rods, of the middle lower part of the needle rod frame; and both the moving mechanism and the up-down driving mechanism are in control connection with a controller. According to the technical scheme provided by the invention, the movement of the needle rod frame caused by vibration force generated in up-down movement of the needle rods can be avoided and the needle rods are ensured to be accurate and controllable in position, so that the needle rods before and after replacement are same in position and the tightness of stitch connection in color change is ensured; the time for locking and unlocking the needle rods is short; and the color change efficiency is improved.

Description

technical field [0001] The invention relates to an automatic production equipment for carpets, in particular to a color-changing mechanism for a fully automatic computerized jacquard machine. Background technique [0002] In the prior art, the carpet automatic jacquard machine can only realize flocking of a single color, and when the pattern is more complex, it can only be realized by manually stopping the machine to change the thread, which is inefficient and the stitches are not tightly connected when changing the thread. [0003] In the field of textiles, the color-changing knitting mechanism by moving the needle bar is widely used in embroidery machines. The processing defect of the color cam makes it happen that the color change is not in place or the color change is stuck during the color change process, resulting in low work efficiency. [0004] Moreover, in the prior art, the number of needle bars has increased from 3 to 15, and the burden on the needle bar frame is...

AI Technical Summary

Problems solved by technology

[0002] In the prior art, the carpet automatic jacquard machine can only realize the flocking of a single color. When the pattern is more complex, it can only be realized by manually stopping the machine and changing the thread. The efficiency is low, and the stitches are not tightly connected when changing the thread.

[0003] In the field of textiles, the color-changing knitting mechanism by moving the needle bar is widely used in embroidery machines. The processing defect of the color cam makes it happen that the color change is not in place or the color change is stuck during the color change process, resulting in low work efficiency

[0004] Moreover, in the prior art, the number of needle bars has increased from 3 to 15, and the burden on the needle bar frame is very heavy, which causes slow color change of the needle bar frame, wrong color change, easy damage to parts, etc., resulting in production efficiency. Low, so fully automatic use of jacquard machine using the needle bar color change mechanism of embroidery machine will increase the failure rate of jacquard machine head and shorten the service life
