[0002] Computer embroidery machines have been widely used in the textile industry. During the operation of computer embroidery machines, a thread clamp is needed to clamp the embroidery thread, so that the embroidery thread has a certain tension, which can make the embroidery thread work more stably and improve the processing effect of the embroidery thread.

[0003] However, when the existing tension-adjustable embroidery machine thread clamp is put into use, the compression spring drives the clamping block to limit the embroidery thread, so that the embroidery thread processing is more stable. However, after the existing thread clamp is finished working, the staff needs to maintain and clean the guide block on one side of the clamping block. The staff needs to compress the compression spring with one hand and hold the tool for cleaning with the other hand, which increases the staff's workload. At the same time, the staff needs to maintain and repair more embroidery machines at a time, and there are more thread clamps on one embroidery machine. Since the staff can only clean one thread clamp at a time, the staff's maintenance and cleaning speed is reduced, and the labor intensity is relatively high. Utility Model Content

[0022] See also Figure 1-5As shown, a tension-adjustable embroidery machine thread clamp comprises a support frame 1, which can support the thread clamp, a clamping block 2 is provided on one side of the support frame 1, and the clamping block 2 can clamp the thread on one side of the support frame 1, a fixed block 3 is provided on one side of the clamping block 2, and the tension of the thread can be adjusted under the cooperation of the fixed block 3 and the clamping block 2, and the top of the clamping block 2 is fixedly connected to a connecting rod 4, and a limiting mechanism 5 is provided on one side of the connecting rod 4, and under the cooperation of the limiting mechanism 5 and the connecting rod 4, the clamping block 2 can be moved away from one side of the support frame 1, so as to be able to It is convenient for the staff to clean the guide rod connecting the clamping block 2 and the support frame 1, and the staff does not need to move the clamping block 2 all the time, thereby reducing the workload of the staff and increasing the practicality of the device. One side of the support frame 1 is bolted with an electric telescopic rod 6, and the output shaft of the electric telescopic rod 6 is fixed with a second connecting block 7. Under the action of the electric telescopic rod 6, the second connecting block 7 can be moved on one side of the support frame 1. A rotating mechanism 8 is provided on one side of the second connecting block 7. The surface of the second connecting block 7 is bolted with a fixed sleeve 10, and the inner cavity of the fixed sleeve 10 rotates It is connected with a rotating rod 9, and the rotating mechanism 8 and the rotating rod 9 cooperate with each other. Under the action of the rotating mechanism 8, the rotating rod 9 can be rotated in the inner cavity of the fixed sleeve 10. One end of the rotating rod 9 is fixedly connected to a turntable 11, and the other side of the turntable 11 is bolted with a fixed rod 12. The other end of the fixed rod 12 is bolted with an arc plate 13. The cross-sectional shape of the arc plate 13 is a semicircular design. The number of arc plates 13 is several and corresponds to the number of clamping blocks 2. The inner cavity of the arc plate 13 is equipped with a brush 14. Under the cooperation of the rotating rod 9 and the fixed sleeve 10, the rotating rod 9 can be rotated. The disk 11 drives the arc plate 13 to rotate through the fixed rod 12, so that the brush 14 in the inner cavity of the arc plate 13 can clean the guide rod where the clamping block 2 and the support frame 1 intersect, and can, depending on the number of brushes 14, clean multiple guide rods at the same time, reducing the workload of the staff and speeding up the staff's maintenance and servicing of the wire clamp, thereby increasing the use effect of the wire clamp, and with the cooperation of the electric telescopic rod 6 and the second connecting block 7, the brush 14 can be moved downward, allowing the clamping block 2 and the fixed block 3 to work.

[0023] The limiting mechanism 5 includes a first connecting block 51, one side of the first connecting block 51 is bolted to one end of the connecting rod 4, the inner cavity of the first connecting block 51 is rotatably connected to the limiting rod 52, and the top of the fixed block 3 is bolted to the limiting block 53. There is a recessed area on the surface of the limiting rod 52 and corresponds to the surface of the limiting block 53. With the cooperation of the connecting rod 4 and the first connecting block 51, the limiting rod 52 can be rotated. Then the staff uses the clamping block 2 to make the connecting rod 4 drive the limiting rod 52 to move. The rotating limiting rod 52 can correspond to the surface of the limiting block 53, preventing the spring between the clamping block 2 and the fixed block 3 from rebounding, thereby facilitating the staff to clean the guide rod on the clamping block 2 and the support frame 1 side, reducing the workload of the staff.

[0024] The rotating mechanism 8 includes a hand-turning block 81 arranged on one side of the second connecting block 7, and a rotating shaft 82 is fixed to one side of the hand-turning block 81.

A bevel gear set 83 is fixed to the surface of the rotating shaft 82, and the other side of the bevel gear set 83 is fixedly connected to one end of the rotating rod 9. The bevel gear set 83 is composed of two bevel gears meshing with each other. With the cooperation of the hand-turning block 81 and the rotating shaft 82, the bevel gear set 83 can drive the rotating rod 9 to rotate in the inner cavity of the fixed sleeve 10, so that the brush 14 can clean the guide rod, thereby speeding up the staff's cleaning rate of the wire clamp.

[0025] Working principle: When the staff needs to clean the wire clamp, the staff first rotates the limit rod 52 to make the limit rod 52 and the limit block 53 intertwine with each other, and drives the connecting rod 4 to move the first connecting block 51 through the clamping block 2, and the first connecting block 51 drives the limit rod 52 to move to the other side of the limit block 53. Under the action of the compression spring rebound between the clamping block 2 and the fixed block 3, the limit rod 52 and the surface of the limit block 53 can be brought into contact with each other, so that the clamping block 2 and the guide rod on one side of the support frame 1 can be released, and then the electric telescopic rod is used. 6 makes the second connecting block 7 drive the rotating shaft 82 to move, so that the brush 14 moves to the surface of the guide rod. The staff drives the rotating shaft 82 to rotate through the hand-turning block 81. The rotating shaft 82 causes the rotating rod 9 to rotate in the inner cavity of the fixed sleeve 10 through the bevel gear set 83. The rotating rod 9 causes the fixed rod 12 to drive the arc plate 13 to rotate through the turntable 11. The arc plate 13 drives the brush 14 to clean the surface of the guide rod. After cleaning, the staff moves the brush 14 downward through the electric telescopic rod 6 to enable the wire clamp to work.
