Independently mountable piezoelectric jacquard comb

Abstract

The invention relates to a piezoelectric jacquard comb capable of being installed independently. The piezoelectric jacquard comb comprises a base and a plurality of yarn guide needles fixed on the base and driven by a piezoelectric ceramic wafer. The piezoelectric jacquard comb is characterized by further comprising a housing, the housing comprises a top wall and two side walls connected with the top wall, each side wall is provided with at least one first fixing mechanism and limiting teeth located at the front end of the side wall, each of the two sides of the base is provided with a second fixing mechanism corresponding to the first fixing mechanism on the corresponding side wall of the housing, the first fixing mechanisms on the side walls are matched with the second fixing mechanisms on the base correspondingly to enable the housing to be fixed to the base so as to cover the portion, except the stretching-out portions of the yarn guide needles at the front end, of the piezoelectric jacquard comb after the housing is in place, and the limiting teeth at the front end of each side wall of the housing are matched with the front end of each side face of the base to limit the swing of the yarn guide needles on the outermost sides. Compared with the prior art, the piezoelectric jacquard comb has the advantages that independent installation can be achieved, and the jacquard effect of warp knitting fabric is improved.

Description

technical field [0001] The invention relates to a jacquard comb for weaving, in particular to a piezoelectric jacquard comb which can be installed independently. Background technique [0002] Existing jacquard comb 100 as figure 1 As shown, it generally includes a base 10 and a plurality of yarn guide needles 20 fixed on the base and driven by piezoelectric ceramic chips. Since the outermost yarn guide needles 201 and 2016 have no limit pin tooth protection, the piezoelectric ceramic chips are likely to be bent and damaged when they are stressed during transportation and installation, resulting in jacquard work failure. In addition, since the guide needle is exposed to the outside, it is easy to enter foreign matter during the work of the jacquard comb, resulting in damage to the jacquard. In addition, during jacquard assembly, the swing limit of the outermost yarn guide needle depends on the installation position of adjacent jacquard needles, which requires higher precisi...

Problems solved by technology

Since the outermost yarn guide needles 201 and 2016 have no limit pin tooth protection, the piezoelectric ceramic chips are likely to be bent and damaged when they are stressed during transportation and installation, resulting in Jacquard work failure

In addition, because the guide needle is exposed to the outside, it is easy to enter foreign matter during the work of the jacquard comb, resulting in damage to the jacquard

In addition, during jacquard assembly, the swing limit of the outermost yarn guide needle depends on the installation position of adjacent jacquard needles, which requires higher precision for jacquard assembly, and the outermost yarn guide needle during assembly. The position cannot be precisely controlled, which affects the jacquard effect
