Abstract
The utility model relates to a jacquard machine technical field, in particular to last piece of lifting of bodkin jacquard weave. The jacquard sheet is a sheet-shaped body, the middle part of the jacquard sheet is a thinning part, the two ends of the jacquard sheet are thick section parts, one side surface of the jacquard sheet is inwards sunken to form the thinning part, the thinning part forms an arc-shaped bend, the thinning part is bent towards the direction with the sunken side, and the thick section parts are flat and straight. The requirement on the bending precision of the jacquard sheet is reduced by arranging the thinning part, and the production difficulty and cost are reduced; the thinning part is formed by removing the material from one side and is bent towards the direction of the sunken side, so that the influence of the arrangement of the thinning part on the normal work of the jacquard sheet is avoided.
Description
Technical Field
The utility model relates to a jacquard machine technical field, in particular to last piece of lifting of bodkin jacquard weave.
Background
In the upper plate jacquard mechanism for double-sided jacquard, the core part is an upper jacquard sheet, and the upper jacquard sheet is usually made into a sheet-shaped body with a certain radian, so that the upper jacquard sheet is inserted into the needle groove and then abuts against the needle groove to have certain resistance between the upper jacquard sheet and the needle groove, and the disorder of flowers caused by the automatic falling of the upper jacquard sheet due to gravity, vibration and the like is avoided, as shown in fig. 1 and 2.
When the needle pitch of the knitting machine is smaller, the sheet-shaped body is thinner, the change of the sliding resistance of the jacquard sheet in the needle groove caused by the bending degree is not obvious, and the resistance can not influence the normal work of the knitting triangle; however, when the needle pitch of the knitting machine is large, the thickness of the sheet-like body is thick, the change of the sliding resistance of the jacquard sheet in the needle groove is very large due to the bending degree, the problem that the jacquard sheet cannot be automatically dropped cannot be solved if the resistance is too small, the normal operation of the knitting cam is influenced if the resistance is too large, and the deformation of the inserting sheet is possibly caused by too large extrusion force on the inserting sheet. Therefore, the curvature of the sheet-shaped body needs to be accurately controlled, and the manufacturing cost is high and the difficulty is high.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects in the prior art, the utility model provides a low-cost upper jacquard sheet of a bodkin jacquard.
In order to achieve the above object, the utility model adopts the following technical scheme: a jacquard weave piece that lifts of thick needle jacquard weave, the jacquard weave piece is the platelike body, its characterized in that: the middle part of the jacquard sheet is a thinning part, two ends of the jacquard sheet are thick section parts, one side surface of the jacquard sheet is inwards sunken to form the thinning part, the thinning part forms arc-shaped bending, the thinning part is bent towards the direction with the sunken side, and the thick section parts are flat and straight.
Further, the thinning part has an arc transition between the concave side and the thick section part.
Further, the jacquard sheet is also provided with a needle selection foot, and the needle selection foot is positioned at the thinning part.
Further, the pattern piece is installed in the upper disc jacquard mechanism, and the concave side of the thinning portion faces the front of the upper disc jacquard mechanism in the rotating direction.
From the above description of the present invention, compared with the prior art, the pattern lifting piece of the bobbiner jacquard provided by the present invention has the advantages that the requirement for the bending precision of the pattern lifting piece is reduced by the thinning part, and the production difficulty and cost are reduced; the thinning part is formed by removing the material from one side and is bent towards the direction of the sunken side, so that the influence of the arrangement of the thinning part on the normal work of the jacquard sheet is avoided.

The labels in the figure correspond to the following: 1. the needle selection device comprises a thinning part, 11 recesses, 12 arc-shaped transitions, 2 thick sections and 3 needle selection feet.
Detailed Description
The present invention will be further described with reference to the following detailed description.
Referring to fig. 3 to 6, a jacquard sheet of a thick needle jacquard is a sheet-shaped body, the middle part of the jacquard sheet is a thinning part 1, two ends of the jacquard sheet are thick sections 2, one side surface of the jacquard sheet is inwards sunken to form the thinning part 1, the thinning part 1 is formed into an arc-shaped bend, the thinning part 1 is bent towards the direction with one side of the sunken part 11, the thick sections 2 are flat, the thinning part 1 is provided with an arc-shaped transition 12 between one side of the sunken part 11 and the thick sections, the jacquard sheet is further provided with needle selection feet 3, the needle selection feet 3 are positioned at the thinning part 1, the jacquard sheet is installed in an upper plate jacquard, and one side of the sunken part 11 of the thinning part 1 is towards the front of the rotation direction of the upper plate jacquard.
According to the upper jacquard sheet for the thick jacquard, the arc-shaped bent part is arranged at the thinning part 1 at the middle part, and the thickness of the position is thinner, so that the influence of the bending degree on the resistance is smaller, namely, the requirement on the bending amount precision is reduced, and the production difficulty is reduced; the thinning part 1 is formed by locally removing a material depression 11 from one side surface of the jacquard sheet, and the thinning part 1 is bent towards the direction of one side with the depression 11, so that the other side surface of the jacquard sheet is a flat cambered surface, the flat cambered surface is contacted with an insert sheet to bear force during installation, and the side, provided with the depression 11, of the thinning part 1 is not contacted with the insert sheet, so that the normal working action of the jacquard sheet cannot be influenced by the arrangement of the thinning part 1; the needle selection foot 3 is positioned at the thinning part 1, the jacquard sheet is arranged in the upper disc jacquard mechanism, one side of the dent 11 of the thinning part 1 faces the front of the rotating direction of the upper disc jacquard mechanism, therefore, the lateral force applied to the jacquard sheet by the needle selector during working is inward relative to one side of the dent 22, namely, the stressed part between the jacquard sheet and the insert sheet is always tightly attached to the insert sheet, and the stable operation of the device is ensured.
The above-mentioned only be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and all utilize this design right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
