[0024] Detection mechanism 3 includes support 31 and sliding slot 32, sliding slot 32 is opened in the top of support 31, the inner wall of sliding slot 32 is slidably connected with sliding block 33, the top of sliding block 33 is installed with second bearing 34, the inner wall of second bearing 34 is fixedly connected with second shaft 35, roller two 4 is installed on the outer wall of second shaft 35, and the side of sliding block 33 and the side of the inner wall of sliding slot 32 are fixedly connected with spring 37.

[0025] The sliding block 33 is installed through the detection of the sliding groove 32 in the inner wall of the support 31. The top of the sliding block 33 is provided with the second bearing 34, the inner wall of the second bearing 34 is fixedly connected with the second shaft rod 35, and the second roller 4 is installed on the outer wall of the second shaft rod 35. When the tension of the covering wire changes, the covering wire will exert pressure on the second roller 4, the sliding block 33 will compress the guide rod 36, and the second shaft rod 35 and the second roller 4 will move left and right along the sliding groove 32. At this time, the position of the second roller 4 in the sliding groove 32 can be observed to monitor the tension change of the covering wire.

[0026] Referring to Figure 3 , Figure 4 , the inner wall of the sliding groove 32 is provided with a pressure sensor 10 on one side, one side of the sliding block 33 is fixedly connected with a pressing rod 11, the pressing rod 11 is horizontal with the pressure sensor 10, the inside of the sliding groove 32 is fixedly connected with two guide rods 36, and the inside of the sliding block 33 is provided with two through holes 38 with the same outer diameter as the guide rods 36, and the two guide rods 36 are slidingly connected in the through holes 38.

[0027] The pressure sensor 10 is installed through the sliding groove 32. One side of the sliding block 33 is fixedly connected with the pressing rod 11. When the tension of the covering wire changes, the covering wire will exert pressure on the second roller 4, so that the sliding block 33 compresses the guide rod 36 and drives the second shaft rod 35 and the second roller 4 to move left and right along the sliding groove 32. At this time, the sliding block 33 pushes the pressing rod 11 to move in the sliding groove 32, and the pressure sensor 10 monitors the pressure of the pressing rod 11. When the pressure sensor 10 detects that the pressure is lower than the preset value, the servo motor 8 drives the third roller 7 to move forward and backward along the inner wall of the adjusting mechanism 5. Under the elastic action of the guide rod 36, the third roller 7 drives the sliding block 33 and the second roller 4 to slide along the sliding groove 32 and the two guide rods 36, so as to adjust the tension of the covering wire.

[0028] Referring to Figure 1 , Figure 2 , the adjusting mechanism 5 comprises a support 51 and a third bearing 52. The third bearing 52 is installed on one side of the inner wall of the support 51. The inner wall of the third bearing 52 and the inside of the support 51 are provided with a screw rod 53. The output end of the servo motor 8 is fixedly connected with the screw rod 53. The outer wall of the screw rod 53 is sleeved with a rectangular block 54. The rectangular block 54 is slidingly connected to the inner wall of the support 51. The third roller 7 is rotationally connected to the top of the rectangular block 54.

[0029] The third bearing 52 and the screw 53 can be installed through the support 51 in the adjustment mechanism 5. Since the output end of the servo motor 8 is fixedly connected to the screw 53, when the tension of the covering wire needs to be adjusted, the servo motor 8 is started to drive the screw 53 to rotate. Under the action of the screw, the rectangular block 54 drives the roller 7 to move back and forth along the inner wall of the support 51. At this time, under the elastic action of the guide rod 36, the slider 33 is pushed to drive the roller 4 to slide along the groove 32, which can adjust the tension of the covering wire.

[0030] See Figure 1 , Figure 2 Both the inner wall of the slide 32 and the inner wall of the support 51 are equipped with bellows covers 9.

[0031] The bellows cover 9 prevents dust, oil, and other contaminants from entering the chute 32 and the support 51 and coming into contact with the two guide rods 36, the two springs 37, and the rectangular block 54, thus reducing the frequency of equipment failures and maintenance.

[0032] During operation, rollers 2, 4, and 7 can be installed via the first shaft 22, roller 1, and adjustment mechanism 5. Since the output end of the servo motor 8 is fixedly connected to the adjustment mechanism 5, the coating wire is wound between rollers 2, 4, and 7. When the tension of the coating wire changes, the coating wire will apply pressure to roller 4, causing it to move left and right along the detection mechanism 3. At this time, roller 4 can be observed, and the tension change of the coating wire can be monitored. At the same time, the servo motor 8 is started, pushing roller 7 to move back and forth along the inner wall of the adjustment mechanism 5, so that roller 4 slides left and right along the detection mechanism 3, thereby adjusting the tension of the coating wire.

[0033] The slider 33 can be installed through the groove 32 opened on the inner wall of the bracket 31 in the detection mechanism 3. Since the top of the slider 33 is equipped with a second bearing 34, and the inner wall of the second bearing 34 is fixedly connected to a second shaft 35, and the roller 4 is installed on the outer wall of the second shaft 35, when the tension of the coated yarn changes, the coated yarn will apply pressure to the roller 4. The slider 33 will compress the guide rod 36 and drive the second shaft 35 and the roller 4 to move left and right along the groove 32. At this time, the position of the roller 4 in the groove 32 can be observed to monitor the tension change of the coated yarn.

[0034] The pressure sensor 10 is installed through the sliding groove 32. Since one side of the sliding block 33 is fixedly connected with the pressure rod 11, when the covering wire tension changes, the covering wire will exert pressure on the second roller 4, so that the sliding block 33 compresses the guide rod 36 and drives the second shaft rod 35 and the second roller 4 to move left and right along the sliding groove 32. At this time, the sliding block 33 pushes the pressure rod 11 to move in the sliding groove 32, and the pressure sensor 10 monitors the pressure of the pressure rod 11. When the pressure sensor 10 detects that the pressure is lower than the preset value, the servo motor 8 is driven to push the third roller 7 to move forward and backward along the inner wall of the adjusting mechanism 5. Under the elastic action of the guide rod 36, the sliding block 33 drives the second roller 4 to slide along the sliding groove 32 and the two guide rods 36, so as to adjust the tension of the covering wire.

[0035] The third bearing 52 and the screw rod 53 are installed through the support 51 in the adjusting mechanism 5. Since the output end of the servo motor 8 is fixedly connected with the screw rod 53, when the tension of the covering wire needs to be adjusted, the servo motor 8 is started to drive the screw rod 53 to rotate. Under the action of the screw thread, the rectangular block 54 drives the third roller 7 to move forward and backward along the inner wall of the support 51. At this time, under the elastic action of the guide rod 36, the sliding block 33 drives the second roller 4 to slide along the sliding groove 32, so as to adjust the tension of the covering wire.

[0036] In summary, the device adjusts the tension of the covering wire by the servo motor 8 pushing the third roller 7 to move forward and backward along the inner wall of the adjusting mechanism 5, so that the second roller 4 slides left and right along the detection mechanism 3, thereby avoiding the uneven situation of over-loose or over-tight during the covering of the yarn core.
