Description

Technical Field

[0001] The utility model relates to the field of textile machinery, in particular to a mounting structure and a piezoelectric jacquard device with the mounting structure. Background Art

[0002] A conventional single jacquard is composed of a base, a ceramic sheet and a yarn guide needle, and its structural focus is that a row of piezoelectric ceramic sheets are horizontally installed at specified intervals on a single base to form a jacquard.

[0003] The Chinese utility model patent (application number: 201520556751.1, publication number: CN204982273U) discloses a double jacquard warp knitting machine with a yarn pressure plate. At the application level, multiple jacquards are arranged horizontally and installed on the comb mounting part. Usually, a complete jacquard application consists of two comb mounting parts, and the jacquards on each comb mounting part correspond to odd and even needle positions. A set of complete yarn guide needle applications consists of odd and even rows of needles on two comb mounting parts. When installing, the odd rows and even rows are staggered by one needle, which constitutes a complete set of jacquard applications.

[0004] However, after the two rows of jacquards are installed on the guide bar mounting portion to form a jacquard unit, the positions of the odd-numbered needle rows and the even-numbered needle rows need to be adjusted. Utility Model Content

[0005] The utility model provides a mounting structure and a piezoelectric jacquard device with the mounting structure, the main purpose of which is to overcome the defect that after two rows of jacquards are mounted on a comb mounting part to form a jacquard unit, the positions of odd-numbered needle rows and even-numbered needle rows need to be adjusted.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A mounting structure and a piezoelectric jacquard device having the mounting structure, the piezoelectric jacquard device comprising at least one mounting structure, a plurality of first piezoelectric jacquard elements arranged on the upper surface of the mounting structure, and a plurality of second piezoelectric jacquard elements arranged on the upper surface of the mounting structure, the first piezoelectric jacquard element having at least one first yarn guide needle, the second piezoelectric jacquard element having at least one second yarn guide needle, the first yarn guide needle and the second yarn guide needle being arranged alternately with each other, when the first yarn guide needle is an odd-numbered needle row, the second yarn guide needle is an even-numbered needle row, and when the first yarn guide needle is an even-numbered needle row, the second yarn guide needle is an odd-numbered needle row.

[0008] Furthermore, the mounting structure includes at least one base and a plurality of first comb teeth and a plurality of second comb teeth, at least a portion of the first yarn guide needle is arranged in the corresponding first comb teeth, at least a portion of the second yarn guide needle is arranged in the corresponding second comb teeth, the first comb teeth and the second comb teeth are respectively arranged on the upper and lower sides of the base, and the first comb teeth and the second comb teeth are staggered with each other.

[0009] Compared with the prior art, the beneficial effects produced by the utility model are:

[0010] The utility model has a simple structure and strong practicality. A first yarn guide needle is arranged on the upper surface of the mounting structure, and a second yarn guide needle is arranged on the lower surface of the mounting structure. The first yarn guide needle and the second yarn guide needle are arranged alternately with each other. On the one hand, after the user installs the piezoelectric jacquard device, there is no need to perform secondary adjustments on the odd-numbered needle rows or the even-numbered needle rows. The piezoelectric jacquard device can be used directly after installation, and the overall structure is more compact. On the other hand, the error in the installation and debugging process of the odd-numbered needle rows and the even-numbered needle rows is reduced, thereby achieving the effect of killing two birds with one stone.

[0011] In the utility model, the first comb bar teeth and the second comb bar teeth are arranged in a staggered manner to meet the installation of odd-numbered needle rows and even-numbered needle rows, thereby more accurately limiting the swing of the first yarn guide needle and the second yarn guide needle.

[0012] In the utility model, by respectively arranging the first yarn guide needle and the second yarn guide needle on the first comb bar teeth and the second comb bar teeth, the integration of the piezoelectric jacquard device is improved, so that the piezoelectric jacquard device can be well adapted to the use requirements of a double jacquard warp knitting machine or a triple jacquard warp knitting machine.

[0017] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0018] Embodiment 1, refer to Figure 1A mounting structure and a piezoelectric jacquard device having the mounting structure, the piezoelectric jacquard device comprising at least one mounting structure 1, a plurality of first piezoelectric jacquard elements 2 arranged on the upper surface of the mounting structure 1, and a plurality of second piezoelectric jacquard elements 3 arranged on the upper surface of the mounting structure 1.

[0019] Reference Figure 1 The first piezoelectric jacquard element 2 includes a first substrate, a first piezoelectric ceramic sheet 21 wrapped on the first substrate, at least one first comb bar holding portion 22 arranged on the front of the first piezoelectric ceramic sheet 21, two first conductive sheets 23 respectively arranged on the tail of the first piezoelectric ceramic sheet 21 and at least one first yarn guide needle 4, the first yarn guide needle 4 is arranged on the front of the first comb bar holding end, the first substrate can be a glass fiber sheet, the second piezoelectric jacquard element 3 includes a second substrate, a second piezoelectric ceramic sheet 24 wrapped on the second substrate, at least one second comb bar holding portion 25 arranged on the front of the second piezoelectric ceramic sheet 24, two second conductive sheets respectively arranged on the tail of the second piezoelectric ceramic sheet 24 and at least one second yarn guide needle 5, the second yarn guide needle 5 is arranged on the front of the second comb bar holding end 26, and the second substrate can be a glass fiber sheet.

[0020] Reference Figure 1 and Figure 2 The first yarn guide needle 4 and the second yarn guide needle 5 are arranged alternately. When the first yarn guide needle 4 is an odd-numbered needle row, the second yarn guide needle 5 is an even-numbered needle row. When the first yarn guide needle 4 is an even-numbered needle row, the second yarn guide needle 5 is an odd-numbered needle row.

[0021] Reference Figure 1 and Figure 2 By arranging a first yarn guide needle 4 on the upper surface of the mounting structure 1 and a second yarn guide needle 5 on the lower surface of the mounting structure 1, the first yarn guide needle 4 and the second yarn guide needle 5 are arranged alternately with each other. On the one hand, after the user installs the piezoelectric jacquard device, there is no need to perform secondary adjustments on the odd-numbered needle columns or the even-numbered needle columns. The piezoelectric jacquard device can be used directly after installation, and the overall structure is more compact. On the other hand, the error in the installation and debugging process of the odd-numbered needle columns and the even-numbered needle columns is reduced, achieving the effect of killing two birds with one stone.

[0022] Reference Figure 1In this embodiment, the piezoelectric jacquard jacquard device combines the original odd and even jacquards into one jacquard, which is equivalent to integrating the functions of odd and even needles on one jacquard. Correspondingly, only one comb bar can accommodate this type of jacquard. Compared with the original set of complete jacquards composed of odd and even comb bars, it has the effect of reducing the space occupied by one comb bar and also reduces the number of corresponding transverse axes. For example, a conventional double jacquard requires 4 comb bars and a 4-axis transverse mechanism, while this type of jacquard only requires 2 comb bars and a 2-axis transverse mechanism, thereby saving the space for installing the jacquard and saving a part of the transverse structure required for installation, reducing the cost and increasing reliability.
