Latch needle fixing device for warp knitting machine

Abstract

The invention discloses a latch needle fixing device for a warp knitting machine, and belongs to the technical field of warp knitting machine accessories. The latch needle fixing device comprises a female thrusting needle body, a latch needle embedding groove, a latch needle foot locating groove, a mounting and fixing hole and a needle pressing plate fixing hole are formed in the female thrusting needle body, and the latch needle fixing device is characterized in that a needle pressing plate is further included, a needle pressing plate screw hole and a mounting screw retreating hole are formed in the needle pressing plate, the needle pressing plate screw hole is fixedly connected with the needle pressing plate fixing hole, a needle pressing plate embedding flange cavity is formed in one end of the upper portion of the needle pressing plate, the other end of the upper portion of the needle pressing plate extends to form a needle pressing plate embedding flange, the needle pressing plate embedding flanges of the needle pressing plates of adjacent latch needle fixing devices are matched with the needle pressing plate embedding flange cavity, and position, on the female thrusting needle body, of the latch needle embedding groove and the latch needle foot locating groove faces the needle pressing plate. The needle pressing plate has the good effect of locating a latch needle, and needle replacement is convenient and fast. Other undamaged latch needles cannot be damaged in the needle replacement process, and the quality of fabric cannot be influenced. The good integrity and stability are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of warp knitting machine accessories, in particular to a latch needle fixing device for a warp knitting machine. Background technique [0002] The latch needle fixing device mentioned above is also called the latch needle seat or the latch needle female, and even called the latch needle bed assembly, which is used to set and fix the latch needles of the warp knitting machine, that is to say, fix the latch needles of the warp knitting machine On the latch needle fixing device, the latch needle fixing device is fixed on the needle bed of the warp knitting machine. [0003] In the prior art, the latch needles used for warp knitting machines are usually fixed in the latch needle slots of the pin female body of the latch needle fixing device in a pouring and fixing manner. The length of a pin female body is about 1-2 inches, and each inch The number of needle rows is about 22 pieces, so take the pin female body...

AI Technical Summary

Problems solved by technology

One of the self-evident shortcomings of this method of changing needles is troublesome operation, long cycle and high cost; the second is that when replacing the damaged latch needle 2, the process of melting the welding base 10 is substantially simultaneous to other intact latch needles. The latch needle 2 has been subjected to high-temperature annealing treatment, the hardness, strength and elasticity of the latch needle 2 will be affected, the more times the latch needle 2 is replaced, the greater the impact on the remaining intact latch needle 2

The current solution is: when changing needles, all latch needles 2 on the same pin female body 1 are all replaced, but this negative processing method has caused resource waste on the one hand, and increased the cost of warp knitting machine on the other hand. User's spare parts cost

[0005] In addition, as mentioned above, since hundreds of pin female bodies are arranged on the needle bed of a warp knitting machine, that is, hundreds of latch needle fixing devices are arranged, so it is difficult to make the latch needle fixing devices next to each other. And produce a good interlocking arrangement effect with each other
