Description

Technical Field

[0001] The utility model belongs to the technical field of electronic jacquard machines, and more specifically, particularly relates to an automatic tensioning device for electronic jacquard machines. Background Art

[0002] Electronic jacquard machine uses the interweaving of warp and weft yarns of various colors to form fabrics with certain patterns. Due to its simple structure, high speed and good quality, it greatly improves labor productivity and has been widely used at home and abroad. The automatic tensioning device of electronic jacquard machine mainly refers to the need to adjust the tension of the silk being processed when the electronic jacquard machine is working. Only when the tension of the silk is appropriate can the silk be jacquard better;

[0003] There are various automatic tensioning devices for electronic jacquard machines on the market, but they are generally adjusted manually. Different batches of silk have different tension levels during processing, and it is very inconvenient to manually adjust the tensioning device. In order to achieve the ideal tension level, the jacquard machine needs to work (test the machine) to cooperate with the adjustment personnel to continuously fine-tune the tensioning device. The process is time-consuming and labor-intensive, and the existing automatic tensioning devices for electronic jacquard machines are relatively simple and cannot adjust the tension levels of different silks in the same batch differently.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an automatic tensioning device for an electronic jacquard machine is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an automatic tensioning device for an electronic jacquard machine to solve the above problems.

[0006] The purpose and effect of the automatic tensioning device of an electronic jacquard machine of the utility model are achieved by the following specific technical means:

[0007] An automatic tensioning device for an electronic jacquard machine comprises a box body, a sliding mechanism is installed in the inner cavity of the box body, a limiting shaft is installed between the sliding mechanisms, a plurality of tensioning mechanisms are evenly installed on the limiting shaft, and a wiring roller used in conjunction with the tensioning mechanism is also provided on the box body;

[0008] The tensioning mechanism comprises a T-shaped slide groove installed on the inner wall surface of the box body, a T-shaped slider is slidably installed in the inner cavity of the T-shaped slide groove, an electric telescopic rod is installed on the bottom surface of the T-shaped slider, and a hinge joint is installed on the telescopic end of the electric telescopic rod;

[0009] The tensioning mechanism also includes an annular block installed on the outer wall surface of the limiting shaft, an articulated rod is installed on the outer wall surface of the annular block, a connecting rod is also installed on the outer surface of the annular block, an articulated groove is installed at the other end of the articulated rod, the articulated head of the electric telescopic rod is installed in the articulated groove of the articulated rod, and a cylindrical block is installed at the other end of the connecting rod.

[0010] Furthermore, the two adjacent tensioning mechanisms are arranged crosswise and symmetrically.

[0011] Furthermore, the axis lines of the hinge rod and the connecting rod are colinear, and a plurality of annular grooves are evenly arranged on the outer wall surface of the cylindrical block.

[0012] Furthermore, the sliding mechanism includes a motor and a sliding rod, a screw rod is installed on the rotating end of the motor, a rectangular internal thread block is installed on the screw rod, a rectangular slider is slidably installed on the sliding rod, one end of the limiting shaft is installed and connected to the outer wall surface of the sliding rod, and the other end of the limiting shaft is installed and connected to the side wall surface of the rectangular slider.

[0013] Furthermore, two wiring rollers symmetrically arranged up and down are installed in the middle of the front and rear ends of the box, and the two ends of the wiring rollers are rotatably arranged in the inner cavity of the box.

[0014] Furthermore, rectangular slide grooves are provided in the middle of the left and right side walls of the inner cavity of the box body, the slide rod is installed in the left rectangular slide groove, and the screw rod is installed in the right rectangular slide groove.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. In the utility model, each silk is adjusted and inserted into the annular groove of the cylindrical block in turn, so that silks with the same tensioning degree are in the annular groove of a cylindrical block, and then silks with different tensioning degrees are on different cylindrical blocks. The electric telescopic rod is driven to retract according to the tensioning degree of different silks, and one end of the hinged rod is pulled to rotate with the axis of the annular block as the center of the circle. During the retraction process of the electric telescopic rod, the T-shaped slider at its upper end drives the electric telescopic rod to slide in the T-shaped slide groove, and then the connecting rod at the other end of the annular block rotates with the axis of the annular block as the center of the circle, and then the cylindrical block drives the silk to be distributed in a V shape between the wiring rollers and the cylindrical blocks at both ends. The smaller the tensioning angle, the higher the tensioning degree, and the shorter the electric telescopic rod is retracted, thereby realizing different adjustments to the tensioning degrees of different silks in the same batch.

[0017] 2. In the utility model, when it is necessary to adjust the tensioning point of the tensioned silk (i.e. the contact point position between the cylindrical block and the silk), the motor rotates to drive the screw rod to rotate, driving the rectangular internal thread block to slide on the screw rod, and at the same time driving the rectangular slider to slide on the slide rod, so that the limiting shaft installed between the slide rod and the rectangular slider drives the tensioning mechanism to slide as a whole, thereby realizing the adjustment of the silk tensioning point.
