[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] As attached Figure 1 -Attached Figure 4As shown, a tension adjustment device for a large circular knitting machine comprises a base 1, a groove 2 is provided in the middle position of the base 1, a lifting mechanism 3 is arranged in the groove 2, a lifting plate 4 is drivingly connected to the lifting mechanism 3, a rotating seat 1 5 is arranged on the upper part of the lifting plate 4, an adjusting wheel 6 is rotatably arranged on the rotating seat 1 5, a rotating seat 2 8 is respectively arranged at the positions on the left and right sides of the groove 2 on the base 1, a guide wheel 9 is rotatably arranged on the rotating seat 2 8, and the guide wheels 9 on both sides are responsible for guiding the yarn into the adjusting wheel 6 and guiding the yarn out of the adjusting wheel 6 respectively.

[0019] As attached Figure 2 As shown, the lifting mechanism 3 includes a mounting block 11, a vertical slot 14 and a plurality of limit slots 15 are provided on the front side of the mounting block 11, the left end of the limit slot 15 is connected to the vertical slot 14, a lifting column 12 is provided inside the mounting block 11, a limit rod 13 is connected to the front side of the lifting column 12, and the upper end of the lifting column 12 is rotatably connected to the lifting plate 4. The lifting column 12 can rotate in the mounting block 11, so that the limit rod 13 can move in the vertical slot 14 and the limit slot 15, and the height of the lifting column 12 can be adjusted by inserting the limit rod 13 into the limit slots 15 of different heights, and then adjusting the height of the adjusting wheel 6 to tension the yarn.

[0020] A baffle 16 is provided at the front side of the mounting block 11 at the side of the vertical slot 14, a guide block 17 is connected to the front side of the mounting block 11, the baffle 16 is slidably provided in the guide block 17, a support arm 18 is connected to the front side of the mounting block 11, a positioning hole 1 20 and a positioning hole 2 21 are provided on the baffle 16, a fixing pin 26 is provided on the support arm 18, and the fixing pin 26 can be inserted into the positioning hole 1 20 or the positioning hole 2 21. When the baffle 16 completely covers the vertical slot 14, the fixing pin 26 can be inserted into the positioning hole 1 20, and at this time, the baffle 16 abuts against the limiting rod 13 located in the limiting slot 15, so that the limiting rod 13 cannot be separated from the limiting slot 15, thereby ensuring that the position of the adjusting wheel 6 will not change. When the baffle 16 completely leaves the vertical slot 14 , the fixing pin 26 can be inserted into the second positioning hole 21 , and the limiting rod 13 can be rotated out of the limiting slot 15 , so that the limiting rod 13 can adjust its position, and then adjust the height of the adjusting wheel 6 .

[0021] As attached Figure 3As shown, a sleeve 22 is provided on the upper part of the support arm 18, a fixing pin 26 is passed through the sleeve 22, a mounting groove 23 is provided in the sleeve 22, a positioning ring 24 is connected to the part of the fixing pin 26 located in the mounting groove 23, a spring 25 is connected to the upper part of the positioning ring 24, the upper end of the spring 25 is connected to the top of the mounting groove 23, and a stopper 19 is connected to the part of the fixing pin 26 passing through the sleeve 22. The spring 25 acts on the positioning ring 24, so that the fixing pin 26 has a tendency to move downward, so that the fixing pin 26 is not easy to be separated after being inserted into the positioning hole 1 20 or the positioning hole 2 21. When the fixing pin 26 needs to be pulled out from the positioning hole 1 20 or the positioning hole 2 21, the stopper 19 needs to be used to drive the fixing pin 26 to rise.

[0022] Vertical guide rods 7 are arranged on both sides of the groove 2. The guide rods 7 pass through the lifting plate 4 to guide the movement of the lifting plate 4 to ensure the vertical lifting of the lifting plate 4 and avoid the adjustment wheel 6 from deflecting and affecting the tensioning effect.

[0023] As attached Figure 1 , Attachment Figure 4 As shown, at least one rotating seat 28 is installed on the base 1 through an adjusting mechanism 10, and the adjusting mechanism 10 includes a support frame 27 installed on the base 1, a threaded sleeve 28 is installed on the support frame 27, and an adjusting screw 29 is connected to the inner thread of the threaded sleeve 28. A support block 30 is connected to the side of the rotating seat 28, and the upper end of the adjusting screw 29 is rotatably connected to the support block 30. By rotating the adjusting screw 29, the support block 30 is driven to descend, so that the height of the guide wheel 9 is lowered, and the height difference between the guide wheel 9 and the adjusting wheel 6 is changed, so that the yarn can be tensioned.

[0024] A receiving groove 31 is provided on the base 1 corresponding to the lower portion of the rotating seat 2 8 installed by the adjusting mechanism 10. When the height of the rotating seat 2 8 is adjusted by the adjusting mechanism 10, the lower end of the rotating seat 2 8 can be lowered into the receiving groove 31, thereby increasing the distance that the rotating seat 2 8 can be lowered, thereby achieving a better tensioning effect on the yarn.
