Anti-disorder needle withdrawing device of double-sided jacquard machine

Abstract

The invention provides an anti-disorder needle withdrawing device of a double-sided jacquard machine. The anti-disorder needle withdrawing device comprises a needle dial, a pattern bit, a needle selector and a damper, wherein the pattern bit is placed in a needle groove, the damper exerts force on the side wall of the pattern bit, so that the pattern bit has no moving relative to the needle grooveunder the condition that the pattern bit is not driven by the needle selector, then a knitting needle connected with the pattern bit is static, the damper comprises a barrel body, the barrel body isinstalled in a placement hole in the inner wall of the needle groove, a plug is installed at the top of the barrel body, the plug enables the barrel body to form a counter bore, a first spring is placed in the counter bore, a first steel ball is placed at an opening of the counter bore, a piston is movably arranged in the placement hole, the upper end of the piston abuts against the first steel ball, a polyurethane body is arranged at the lower end of the piston, and the lower end of the polyurethane body extends out of the placement hole, enters the needle groove and abuts against the side wall of the pattern bit. According to the anti-disorder needle withdrawing device, the phenomenon of disordered needle withdrawing caused by external vibration can be avoided.

Description

technical field

[0001] The invention relates to the technical field of jacquard machines, in particular to an anti-disorder needle ejection device for double-sided jacquard machines. Background technique

[0002] At present, with the rapid development of the textile industry, textile mechanical devices have developed rapidly. In the textile industry, double-sided jacquard machines are widely used. When double-sided jacquard machines are working, needle selectors are particularly important. Some abnormalities are prone to occur in the work, such as wrong flowers, random flowers and needles being stolen in the jacquard machine. These problems cause many product quality problems and cause high maintenance costs. In addition, in daily production, there are often phenomena of sudden random needle ejection, most of which are caused by the malfunction of jacquard sheets caused by external vibration interference.

[0003] In view of the above situation, those skilled in the art nee...
