Description

Technical Field

[0001] The utility model relates to the field of silk threads, and in particular to a silk thread tension regulating device. Background Art

[0002] Thread tension adjustment is a crucial part of the textile production process. It directly affects the quality and production efficiency of textiles. Thread tension adjustment can increase the stability of the thread throughout the production process and avoid problems such as breakage, rubbing and rollover.

[0003] At present, the adjustment of the wire tension is mostly carried out in the form of a tension roller. Specifically, the height of the tension roller is adjusted to change the force of resistance to the wire to adjust the tension. In actual applications, this type of adjustment is found to have a certain degree of slide rails in the height direction for sliding adjustment in order to meet the up and down sliding of the tension roller. As a result, the slide rails occupy a large area, resulting in a waste of space resources.

[0004] Therefore, we make improvements to this and propose a wire tension adjustment device. Utility Model Content

[0005] The utility model aims to provide a wire tension regulating device, which solves the problem that the existing wire tension regulating device easily causes waste of space resources when in use.

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

[0007] A wire tension adjustment device comprises a plate body and a first support arm and a second support arm rotatably arranged inside the plate body, wherein the plate body is further provided with an adjustment element for driving the first support arm and the second support arm to adjust a relative angle;

[0008] A tension roller group is fixed to the top of each of the support arms 1 and 2, a support seat is fixed to both sides of the plate body, a support rod is fixed to one side of the support seat, and an extension rod is hinged to the end of the support rod;

[0009] Wherein, a guide roller group is fixed to the outer end of the extension rod, and a fastening sleeve is threadedly assembled on the surfaces of the support rod and the extension rod.

[0010] As a preferred technical solution of the present application, the support arm 1 includes a main arm, a secondary arm and an adjustment arm;

[0011] The main arm and the auxiliary arm are respectively slidably sleeved on the two ends of the adjusting arm, and the surfaces of the main arm and the auxiliary arm are both threadedly provided with positioning bolts for forming abutment and fixing with the adjusting arm.

[0012] As a preferred technical solution of the present application, the main arm is movably connected to the inner wall of the plate body, and one end of the auxiliary arm is fixed to the tension roller group.

[0013] As a preferred technical solution of the present application, the structures of the support arm 1 and the support arm 2 are the same.

[0014] As a preferred technical solution of the present application, the adjusting element comprises a gear 1 and a gear 2 meshing with each other;

[0015] The gear 1 and the gear 2 are coaxially fixed to the corresponding main arms respectively;

[0016] A servo motor fixed to the plate body is also transmission-connected to one side of the gear 2.

[0017] As a preferred technical solution of the present application, the tops of both sides of the plate body are provided with storage grooves connected to the interior, and positioning rubber knobs are fixed in the storage grooves.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] In the scheme of this application:

[0020] By setting the support arm 1 and the support arm 2, the traditional tension adjustment is changed to be adjusted straight up and down, so that there is no need for a long sliding block for matching use. The relative angle adjustment of the support arm 1 and the support arm 2 can be achieved only by two relatively meshing gears, which satisfies the adjustment of the wire tension and effectively saves space resources. At the same time, through the retractable characteristics of the support arm 1 and the support arm 2 themselves, the tension adjustment strength can be increased by extending the height of the tension roller group during use, and the height of the tension roller group can be reduced after use to meet the folding requirements of storage;

[0021] At the same time, the guide roller groups located on both sides of the plate body can realize the guided conveying of the silk thread and can also be turned over and folded after use to further reduce the overall space occupied by the adjusting device. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] like Figure 1-Figure 5 As shown, this embodiment provides a wire tension adjustment device, comprising a plate body 1 and a support arm 11 and a support arm 2 12 rotatably arranged inside the plate body 1, and an adjustment element 2 for driving the two support arms 11 and 12 to adjust the relative angle is also provided inside the plate body 1;

[0039] A tension roller group 13 is fixed to the top of the support arm 11 and the support arm 2 12, and a support seat 14 is fixed to both sides of the plate body 1, a support rod 15 is fixed to one side of the support seat 14, and an extension rod 16 is hinged to the end of the support rod 15, wherein a guide roller group 17 is fixed to the outer end of the extension rod 16, and a fastening sleeve 18 is threadedly assembled on the surface of the support rod 15 and the extension rod 16;

[0040] The adjusting element 2 includes a gear 1 21 and a gear 2 22 meshing with each other. The gear 1 21 and the gear 2 22 are coaxially fixed to the corresponding main arm 110, and a servo motor 23 fixed to the plate body 1 is also transmission-connected to one side of the gear 2 22.

[0041] Start the servo motor 23 so that its output end drives the gear 1 21 and the gear 2 22 to rotate. Since the gear 1 21 and the gear 2 22 rotate in opposite directions, the support arm 1 11 and the support arm 2 12 connected thereto rotate accordingly. During the rotation of the support arm 1 11 and the support arm 2 12, the tension roller group 13 connected thereto has different points in the swinging process. Therefore, when the angle between the support arm 1 11 and the support arm 2 12 is smaller, the tension given to the silk thread is greater. Similarly, when the angle between the support arm 1 11 and the support arm 2 12 is larger, the tension given to the silk thread is smaller.

[0042] like Figure 1 and Figure 2 As shown, Figure 1 is a schematic diagram of the state where the support arm 1 11 and the support arm 2 12 are unfolded, Figure 2 is a schematic diagram of the storage state of the support arm 11 and the support arm 2 12. At the same angle, Figure 1 Relative to Figure 2As shown, the tension given to the silk thread is greater, so the length of the support arm 11 and the support arm 2 12 can be adaptively adjusted according to the actual tension situation;

[0043] After actual application, by shortening the support arm 11 and the support arm 2 12 to the minimum length, the support arm 11 and the support arm 2 12 can be effectively stored, thereby reducing the overall space occupied by the device;

[0044] The supporting arm 11 comprises a main arm 110, a secondary arm 111 and an adjusting arm 112. The main arm 110 and the secondary arm 111 are respectively slidably mounted on the two ends of the adjusting arm 112, and the surfaces of the main arm 110 and the secondary arm 111 are both threadedly provided with positioning bolts 113 for contacting and fixing with the adjusting arm 112.

[0045] The main arm 110 is movably connected to the inner wall of the plate body 1, one end of the auxiliary arm 111 is fixed to the tension roller group 13, and the structures of the support arm 1 11 and the support arm 2 12 are the same;

[0046] Take out the positioning bolt 113, adjust the main arm 110 and the auxiliary arm 111 on the surface of the adjusting arm 112, so that the adjusting arm 112 is exposed to different lengths, so as to adjust the effective supporting length of the corresponding supporting arm 11 and the supporting arm 2 12, and then rotate the positioning bolt 113 to lock it;

[0047] The tops of both sides of the plate body 1 are provided with receiving grooves 19 communicating with the interior, and positioning rubber knobs 190 are fixed in the receiving grooves 19;

[0048] like Figure 1 The figure shows the state where the wire is tensioned, at which time the tightening sleeve 18 covers the connection between the support rod 15 and the extension rod 16, so that the support rod 15 and the extension rod 16 are located on the same horizontal plane to achieve the guiding effect of the guide roller group 17 at the top thereof;

[0049] After the wire is tightened, the tightening sleeve 18 is rotated to move it onto the support rod 15, and then the extension rod 16 is flipped over to place it into the corresponding storage groove 19, so that it can be stored, further reducing the overall space occupied by the device.

[0050] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods.
