Piezoelectric ceramic jacquard comb

Abstract

The invention provides a piezoelectric ceramic jacquard comb. The piezoelectric ceramic jacquard comb comprises a main body and jacquard needles, wherein the main body comprises a base and a comb sheet head; the comb sheet head is provided with a plurality of comb sheets; a groove is formed in the base; a bulge is arranged on the corresponding comb sheet head; a weight reducing groove is further arranged at the lower end of the comb sheet head; and the comb sheet head is made of an alloy material. The piezoelectric ceramic jacquard comb provided by the invention adopts a structure that the jacquard comb main body is divided into the base and the comb sheet head, which are arranged by sections, and the comb sheet head is made of the alloy material with higher strength, so that the anti-collision and anti-deformation capabilities can be obviously improved and a limiting function of the jacquard needles is improved; and a phenomenon that the jacquard needles are excessively vibrated and are interfered with other knitting needles and then are broken is avoided; and the structure can be used for manufacturing NO.E36 or No.E40 jacquard combs with higher density.

Description

Technical field: [0001] The invention belongs to accessories in the field of warp knitting machinery, and in particular relates to a piezoelectric ceramic jacquard comb. Background technique: [0002] At present, the highest machine number of the existing warp knitting machine piezoelectric ceramic jacquard comb is only E32 jacquard comb. The machine number is E32 jacquard comb, which means that there are 32 jacquard needles in 1 inch. The current general-purpose E32 jacquard comb The material of the main body is an aluminum alloy cast in one piece. The head of the main body is provided with a plurality of combs, and the gap between the two combs is provided with Jacquard. The two sides of the Jacquard needle are provided with piezoelectric ceramics. The ceramics will be alternately elongated under the alternating drive of high-frequency current, so that the Jacquard needles will swing left and right. The Jacquard needles rely on the comb pieces for gearing, and the existing...

Problems solved by technology

[0002] At present, the highest machine number of the existing warp knitting machine piezoelectric ceramic jacquard comb is only E32 jacquard comb. The machine number is E32 jacquard comb, which means that there are 32 jacquard needles in 1 inch. The current general-purpose E32 jacquard comb The material of the main body is an aluminum alloy cast in one piece. The head of the main body is provided with a plurality of combs, and the gap between the two combs is provided with Jacquard. The two sides of the Jacquard needle are provided with piezoelectric ceramics. The ceramics will be alternately elongated under the alternating drive of high-frequency current, so that the Jacquard needles will swing left and right. The Jacquard needles rely on the comb pieces for gearing, and the existing structure of the Jacquard combs will be increased to 36 Jacquard needles per inch. The strength of the left and right limit combs will not be high enough, especially when the machine speeds up, it will not be able to effectively limit the swinging jacquard needles, resulting in inaccurate left and right swing positions of the jacquard needles driven by high-frequency current , often collide and cause broken needles, affecting the speed of the warp knitting jacquard machine and the stability of the machine

Due to the limited structural strength of the current aluminum alloy material, it is currently impossible to increase the number of combs by reducing the thickness of the limit combs, and cannot produce higher density E36 or E40 jacquard combs.
