[0053] In the loop-forming process of the warp knitting machine, the accessories such as the knitting needle, the knock-over, the guide needle and the sinker generate heat in the process of knitting yarn. After long-time operation of the machine, the temperature of the loop-forming accessories will be increased, which will cause the pitch of the knitting needle and the guide needle to change, the loop-forming accessories to interfere with each other, and thus affect the quality of the fabric and the production efficiency of the machine.

[0054] Part of the warp knitting machine sets a fan, arranges the air supply pipe at the warp knitting machine, and sets a plurality of air outlets on the air supply pipe, so as to cool the loop-forming accessories.

[0055] Therefore, the present application provides a constant temperature unit 1 for loop-forming accessories of a warp knitting machine, which is used for cooling the loop-forming accessories to ensure that the loop-forming accessories can be kept at a relatively suitable temperature, and has the effects of small noise, low cost, small space occupation, large air volume and good cooling effect.

[0056] Please refer to Figure 1 and Figure 2 In specific embodiments, the constant temperature unit 1 for loop-forming accessories of a warp knitting machine includes an angle adjusting support and a cooling fan 12. The angle adjusting support includes a bottom plate 10, a support plate 11 and a locking structure. The bottom plate 10 is connected with the bar slot steel 2 of the warp knitting machine. The support plate 11 is arranged towards the loop-forming accessories 3 of the warp knitting machine, and is hinged to the bottom plate 10 and can be flipped relative to the bottom plate 10. The locking structure is used for locking the position of the bottom plate 10. The cooling fan 12 is arranged at the support plate 11 and faces the loop-forming accessories.

[0057] The constant temperature unit 1 of the warp knitting machine's loop-forming accessories uses a cooling fan 12 to replace the air outlet of the existing air duct to cool the loop-forming accessories. This reduces the noise of the airflow, increases the air volume, and significantly improves the cooling effect. It solves the problem of needle pitch changes caused by heat in the loop-forming accessories, avoids interference between them, and maintains a constant and stable temperature during long-term operation, ensuring product quality and machine efficiency. Furthermore, it occupies less space compared to fans and ductwork. The cooling fan 12 is mounted on the channel steel 2 of the warp knitting machine's counter via an angle-adjustable bracket. The support plate 11 of the angle-adjustable bracket faces the loop-forming accessories 3 and is hinged to the base plate 10.
