[0037] Furthermore, the lifting mechanism includes a cylinder 22, the bottom end of the cylinder 22 is fixedly connected to the inside of the box 20, the top end of the cylinder 22 is fixedly connected to a connecting rod 23, the left and right sides of the connecting rod 23 are fixedly connected to a connecting frame 26, the top end of the connecting frame 26 is fixedly connected to a support seat 28, and two groups of support seats 28 are provided, and rotating rollers 29 are rotatably connected to the two groups of support seats 28, and the outer side of the rotating rollers 29 is sleeved with a rubber sleeve, the top end of the connecting frame 26 contacts the bottom end of the shell 55, and the inside of the shell 55 is rotatably connected to two groups of rotating cylinders 54, the top end portion of the rotating cylinder 54 is exposed to the outside of the shell 55, the top end of the rotating cylinder 54 contacts the bottom end of the rotating roller 29, the inside of the shell 55 is filled with a lubricant, and the rear end of the shell 55 fits with the connecting rod 23;

[0038] Through the structural design of the lifting mechanism, the cylinder 22 is started, and the cylinder 22 drives the rotating roller 29 to move upward until the rotating roller 29 extends from the inside of the box 20. At this time, the rotating roller 29 can contact the bottom end of the yarn, so that the lubricant is attached to the yarn. At this time, when the yarn passes through the conveying roller, the lubricant attached to the surface of the yarn is attached to the conveying roller, thereby completing the lubrication of the conveying roller and reducing the friction of the yarn during the conveying process, so as to reduce the wear on the yarn surface and reduce the risk of yarn breakage. When the rotating roller is not needed When the rotating roller 29 is in the box 20, the rotating roller 29 can be stored in the box 20 to reduce the interference of the external environment on the rotating roller 29, so as to facilitate the normal use of the rotating roller 29. When working, the cylinder 22 is started, the cylinder 22 drives the connecting rod 23 to move upward, and the connecting rod 23 drives the two sets of connecting frames 26 to move upward. The bottom end of the support seat 28 is fixed on the connecting frame 26, so the rotating roller 29 will move upward. When the rotating roller 29 extends from the box 20 and moves upward to the maximum height, the top end of the rotating roller 29 will contact the bottom end of the yarn, and the yarn will be in During the traction and conveying process, the rotating roller 29 is driven to rotate, and the bottom end of the rotating roller 29 contacts with the two sets of rotating cylinders 54, thereby driving the two sets of rotating cylinders 54 to rotate. Most of the bottom end of the rotating cylinder 54 is located inside the shell 55 and keeps in contact with the lubricant inside the shell 55. The lubricant inside the shell 55 will adhere to the surface of the rotating roller 29 as the rotating cylinder 54 rotates, and then the rotating roller 29 contacts with the yarn, and the lubricant adheres to the bottom end of the yarn. At this time, after the yarn is transported to the device body 1, the lubricant attached to the yarn will adhere to the lubricant inside the shell 55. The conveying roller of the device body 1 is attached to complete the lubrication of the conveying roller of the device body 1. Similarly, when the cylinder 22 is started again to drive the rotating roller 29 to move downward, the rotating roller 29 can be stored in the box body 20, wherein the outer side of the rotating roller 29 is provided with a rubber sleeve, so that the yarn can smoothly drive the rotating roller 29 to rotate, and the rotating roller 29 can also smoothly drive the rotating cylinder 54 to rotate. Due to the characteristics of the polyester yarn itself, even if the lubricant adheres to the bottom end of the yarn, part of the lubricant can penetrate to the other side of the yarn.

[0039] Furthermore, the moving mechanism includes two groups of moving plates 34, the left and right sides of the moving plates 34 are fixedly connected with fixed blocks 33, the fixed blocks 33 are inserted with fixed rods 31, the fixed rods 31 are T-shaped, the fixed rods 31 penetrate the fixed blocks 33, the fixed rods 31 are fixedly connected to the inner wall of the box body 20, a first spring 32 is sleeved on the fixed rod 31, the two sides of the first spring 32 are respectively fixedly connected to the fixed blocks 33 and the inner wall of the box body 20, the fixed blocks 33 are rotatably connected to the slider 36, the slider 36 is slidably connected to the inside of the movable groove 38, the bottom end of the slider 36 is fixedly connected to the second spring 37, the bottom end of the second spring 37 is fixedly connected to the inner wall of the movable groove 38, the movable groove 38 is provided on the pushing rod 40, the bottom end of the pushing rod 40 is rotatably connected to the connecting block 39, and the bottom end of the connecting block 39 is fixedly connected to the support seat 28;

[0040] Through the structural design of the moving mechanism, when the rotating roller 29 moves upward, the two groups of moving plates 34 will first move to both sides to avoid the rotating roller 29 from abutting against the two groups of moving plates 34 when moving, and ensure that the rotating roller 29 can normally extend from the inside of the box body 20. When the rotating roller 29 is stored in the box body 20, the two groups of moving plates 34 will approach each other, thereby shielding the through groove 35 to reduce the adhesion of external dust or debris on the surface of the rotating roller 29, which helps to keep the rotating roller 29 clean. During operation, when the cylinder 22 drives the connecting frame 26 to move upward through the connecting rod 23, the connecting block 39 will also move upward together, and the two groups of push rods 40 connected to the connecting block 39 will rotate, and the top of the push rod 40 will first push the fixed block 33 to slide on the fixed rod 31. The first spring 32 is compressed, and the fixed block 33 is fixed on the moving plate 34 to drive the moving plate 34 to move. The two groups of moving plates 34 will move away from each other so that the rotating roller 29 can extend normally from the inside of the box body 20. When the first spring 32 is compressed to the maximum limit, the push rod 40 continues to rotate and the second spring 37 will be compressed. The slider 36 slides in the movable groove 38 until the push rod 40 rotates to a horizontal state. At this time, the rotating roller 29 will also move upward to the maximum height, wherein the elastic force of the second spring 37 is greater than that of the first spring 32. The design of the slider 36 and the second spring 37 allows the push rod 40 to rotate to a horizontal state, so that when the rotating roller 29 moves upward, the push rod 40 will not be unable to continue to rotate due to the compression of the first spring 32 to the maximum limit.

[0041] Furthermore, the scraping mechanism includes an extension rod 27, which is fixedly connected to the connecting frame 26, and the extension rod 27 is slidably connected to the inside of the U-shaped groove 42.

The side of the extension rod 27 away from the connecting frame 26 is rotatably connected to the bottom end of the long rod 43, and the top end of the long rod 43 is rotatably connected to the top block 45. The side of the top block 45 away from the long rod 43 is fixedly connected to the limiting block 44, and the limiting block 44 is slidably connected to the limiting groove 46. The limiting groove 46 is opened on the box body 20, and the top end of the top block 45 abuts against the bottom end of the mounting plate 50. The top block 45 The mounting plate 50 and the mounting plate 50 are both trapezoidal in design. The mounting plate 50 is fixedly connected to the mounting rod 51. The bottom end of the mounting rod 51 is slidably connected to the support rod 48. The top and bottom ends of the support rod 48 are fixedly connected with a protrusion 49. The protrusion 49 is fixedly connected to the box body 20. A third spring 47 is sleeved on the support rod 48. The top end of the third spring 47 is fixedly connected to the protrusion 49. The bottom end of the third spring 47 abuts against the mounting rod 51. The mounting plate 50 and the mounting rod 51 are both fixedly connected to the scraper 56. The front end of the scraper 56 is close to the collecting tank 52. The bottom end of the collecting tank 52 is fixedly connected to the cover plate 21.

[0042] Through the structural design of the scraping mechanism, when the rotating roller 29 contacts the yarn, the scraper 56 will move upward and contact the bottom end of the yarn. The scraper 56 can scrape off the excess lubricant on the bottom end of the yarn to reduce the loss of the lubricant. At the same time, during the scraping process, the scraper 56 can also allow the lubricant to be evenly distributed on the yarn to improve the lubrication effect. Similarly, when the top block 45 moves in the direction away from the mounting plate 50, the mounting rod 51 will move downward under the action of the third spring 47, so that the scraper 56 no longer contacts the bottom end of the yarn.

[0043] Furthermore, a guide rod 24 is inserted into the connecting rod 23, and the top and bottom ends of the guide rod 24 are fixedly connected to the bottom end of the cover plate 21 and the inner wall of the box body 20 respectively;

[0044] During operation, the guide rod 24 is inserted in the middle position of the connecting rod 23. When the cylinder 22 drives the connecting rod 23 to move upward, the guide rod 24 can guide the movement of the connecting rod 23 to ensure the stable movement of the connecting rod 23, so that the rotating roller 29 can remain stable during movement.

[0045] Furthermore, the bottom end of the connecting frame 26 is fixedly connected to a supporting column 25, and the bottom end of the supporting column 25 contacts the inner wall of the box body 20;

[0046] During operation, the support column 25 is fixed to the bottom end of the connecting frame 26 . When the rotating roller 29 is stored in the box body 20 , the support column 25 contacts the inner wall of the box body 20 to provide support for the bottom end of the connecting frame 26 .

[0047] Furthermore, an extension plate 53 is fixedly connected to the inner wall of the box body 20 , and the size of the extension plate 53 matches the size of the shell 55 . A handle is fixedly connected to the front end of the shell 55 .

[0048] During operation, when the rotating roller 29 is located inside the box body 20, the handle fixed at the front end of the shell 55 is pulled to pull the shell 55 out of the box body 20 to add lubricant inside the shell 55. Since a rubber ring is provided on the outside of the rotating roller 29, the rotating cylinder 54 can move normally under the rotating roller 29 without abutting against the rotating roller 29.

When the cylinder 22 drives the rotating roller 29 to move upward, the two sets of push rods 40 push the moving plates 34 to move to both sides. When the first spring 32 is compressed to the maximum limit, the second spring 37 is gradually compressed to ensure that the two sets of push rods 40 can rotate to a horizontal state, so that the rotating roller 29 can smoothly extend from the inside of the box 20.

[0054] S2, the yarn passes through the rotating roller 29 and drives the rotating roller 29 to rotate, and the rotating roller 29 drives the two sets of rotating cylinders 54 at the bottom to rotate. When the rotating cylinder 54 rotates, the lubricant inside the shell 55 will adhere to the rotating roller 29, and the lubricant will adhere to the bottom of the yarn through the contact between the rotating roller 29 and the yarn;
