Description

Technical Field

[0001] This utility model relates to the field of fabric production technology, and in particular to an electronic jacquard machine for fabric production. Background Technology

[0002] An electronic jacquard machine for fabric production is a type of textile equipment that uses computer information processing technology to convert the pattern information of jacquard fabrics into control information for the jacquard machine. The electromagnetic needle selection mechanism of the electronic jacquard machine is controlled by a computer program and coordinated with the mechanical movement of the textile machine to achieve jacquard weaving of the fabric.

[0003] Traditional electronic jacquard machines used in fabric production are prone to noise when lifting the blade at high speeds. Frequent lifting and lowering of the blade can cause yarn vibration due to inertia, and the increased friction between the yarn and the edge of the blade's limiting groove can easily lead to fuzz or even yarn breakage. Furthermore, when it is necessary to lift the blade at an angle, the yarn is prone to instantaneous tension changes, which can also cause yarn breakage. Utility Model Content

A fixing block 9 is fixedly connected to the bottom of the sliding plate 10. A first universal ball 18 is movably connected to the inner wall of the fixing block 9. When the first universal ball 18 causes the lifting knife 8 to vibrate or the yarn to stretch, the lifting knife... 8.

The lifting knife 8 is fixedly connected to the bottom of the square plate 17. The buffer mechanism is set outside the fixed block 9. The buffer mechanism is used to buffer the lifting knife 8. In specific use: the sliding plate 10 drives the lifting knife 8 to reciprocate and raise and lower to control the raising and lowering of the warp yarn. During this process, the lifting knife 8 generates an impact, which drives the first universal ball 18 to rotate. The buffer mechanism reduces the noise of the lifting knife 8 and slows down the yarn vibration.
