In order to solve the problem in the prior art that the conductive sheet is fixed on the inner wall of the sleeve, the conductive sheet will be worn after the sleeve is used for a long time, and the fixed conductive sheet is not convenient to replace, and can only be replaced together with the sleeve, resulting in a high maintenance cost.

An annular limiting groove is arranged on the upper end surface of the needle sleeve, and the upper end of each bar slot is connected to the annular limiting groove. The upper ends of multiple conductive strips extend to the inside of the annular limiting groove and are fixedly connected with a conductive ring. When the conductive strip is worn due to long-term use, the conductive strip can be replaced separately without replacing the entire needle sleeve, which not only reduces the maintenance cost, but also improves the maintainability and service life of the equipment.

Description

Technical Field

[0001] The utility model relates to the field of knitting machinery, in particular to a needle cylinder sleeve of a seamless underwear machine with a static electricity decoupling function. Background Art

[0002] The seamless knitting underwear machine is a molding production equipment specially used for the production of seamless knitwear. It uses high-speed rotating needles to interweave, rub, cut and other operations between yarn and elastic bands to achieve fast and efficient manufacturing of underwear. This machine is usually equipped with components such as a feeding device, a needle drive system, an auxiliary device and a discharging device. The seamless knitting underwear machine can directly use yarn as raw material to produce finished underwear (only simple cutting and sewing are required), without cutting and sewing the fabric to form clothing like other weaving or knitting machines. In addition, the seamless knitting underwear machine is also widely used in the production of various clothing categories such as swimwear and sportswear, showing strong production capacity and adaptability. When the seamless knitting underwear machine is working, the textile needs to be transmitted by negative pressure, and the textile is sucked out by the air in the syringe sleeve.

The needle sleeve for a seamless underwear machine is equipped with an anti-static component, and the static electricity on the inner wall can be transmitted to the conductive ring by using the conductive sheet, and the connecting line on the front of the conductive ring can be connected to the external metal bracket, and the static electricity directly generated by the connection is led out to the outside, avoiding the occurrence of static electricity accumulation and incomplete static electricity lead-out.

The fixed conductive sheet is not convenient to replace and can only be replaced together with the sleeve, resulting in high maintenance costs. Therefore, the market urgently needs to develop a seamless underwear machine needle sleeve with static electricity decoupling function to help people solve the existing problems.
