Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6A traction mechanism for a warp knitting machine includes two upright plates 1. Square grooves 2 are provided on the outer sides of both upright plates 1. A second traction assembly 4 is installed on the outer sides of the two upright plates 1. The second traction assembly 4 includes a fixed plate 41 installed on the outer sides of the two upright plates 1. Two side plates 42 are connected to one side of the fixed plate 41. A first roller 43 is rotatably connected between the side plates 42. A drive motor 44 is installed on the outer side of one side plate 42. A pulley 45 is installed on the output end of the drive motor 44 and one end of the first roller 43. A belt 46 is sleeved on the outer side of the pulley 45.

[0025] The output of the drive motor 44 drives a pulley 45 to rotate, and this pulley 45 drives another pulley 45 and the first roller 43 in its inner cavity to rotate via a belt 46. This serves as a power source for traction of the warp-knitted fabric. Furthermore, by bringing the two second rollers 310 of the first traction assembly 3 into contact with the other end of the warp-knitted fabric, the rotation of the first roller 43 facilitates friction between the warp-knitted fabric and the second rollers 310, enabling the warp-knitted fabric to be tractioned and transported.

[0026] The inner cavities of the two square slots 2 are jointly equipped with a first traction assembly 3. The first traction assembly 3 includes a movable column 33 installed in the inner cavities of the two square slots 2. A movable seat 32 is slidably connected to the outer side of the movable column 33. A fixed cover 31 is connected to one side of each movable seat 32. A moving groove 38 is provided on the corresponding side of each fixed cover 31. Two sliders 39 are provided in the inner cavity of each fixed cover 31. A second roller 310 is rotatably connected between each pair of sliders 39. A servo motor 312 is installed on the outer side of one of the fixed covers 31. The output end of the servo motor 312 passes through the fixed cover 31 and is connected to a rotating shaft 318. A gear 313 is installed on the outer side of the rotating shaft 318. Two toothed plates 315 mesh on the outer side of the gear 313. A connecting block 314 is connected to one side of each toothed plate 315. One end of each connecting block 314 is connected to a slider 39. The first roller 43 is located between the two second rollers 310.

[0027] The outer side of the movable column 33 is screwed with a first threaded sleeve 34 and a second threaded sleeve 35. The outer side of the first threaded sleeve 34 is connected to a baffle 36. A spring 37 is connected to one side of the movable seat 32. The spring 37 is movably sleeved on the outer side of the movable column 33. One end of the spring 37 is in contact with the baffle 36. Two limiting sleeves 311 are installed on the outer side of the second roller 310. One side of each of the two sliders 39 is connected to a slide block 316. A limiting post 317 is installed in the inner cavity of a fixed cover 31. The slide block 316 is movably sleeved with the limiting post 317.

[0028] Depending on the thickness of the warp-knitted fabric, the vertical distance between the two second rollers 310 and the first roller 43 of the first traction assembly 3 is adjusted. This is achieved by the output of the servo motor 312 driving the rotating shaft 318 to rotate. Simultaneously, the rotating shaft 318 drives the gear 313 on its outer side to rotate, and the gear 313 simultaneously drives the toothed plates 315 on both sides to move in opposite directions. The two toothed plates 315, through the connecting block 314, drive the slider 39 and the second rollers 310 to move in the same or opposite directions, thereby adjusting the vertical distance between the second rollers 310 and the first roller 43. This allows for stable traction operations to accommodate warp-knitted fabrics of different thicknesses. Simultaneously, the other slider 39 at one end of the second roller 310 slides stably up and down on the outside of the limiting post 317 via the sliding block 316, effectively improving the positioning of the second roller 310. The stability is adjusted by the installation of the limiting sleeve 311. The length of the first roller 43 is the same as the distance between the two second rollers 310, which avoids left and right deviation during the traction of the warp-knitted fabric and affects the subsequent winding operation. When it is necessary to adjust the traction tension of the warp-knitted fabric, the first threaded sleeve 34 and the second threaded sleeve 35 are rotated to move the first threaded sleeve 34 and the second threaded sleeve 35 away from the movable seat 32. Then, by moving the movable seat 32 and the entire first traction assembly 3 outside the movable column 33, the two second rollers 310 of the first traction assembly 3 are moved left and right for slight adjustment, so as to adjust the position angle between the second roller 310 and the first roller 43, which facilitates the adjustment of the tension force during the traction of the warp-knitted fabric. Then, by adjusting the two second rollers 310 to move in the same direction, the first roller 43 can jointly squeeze the warp-knitted fabric, which is convenient for traction and transportation.

[0029] Working Principle: This invention uses an external controller connected to a servo motor 312 and a drive motor 44. Depending on the thickness of the warp-knitted fabric, the output of the servo motor 312 drives the rotating shaft 318 to rotate. The rotating shaft 318 simultaneously drives the gear 313 on its outer side to rotate, and the gear 313 simultaneously drives the toothed plates 315 on both sides to move in opposite directions. The two toothed plates 315, through a connecting block 314, drive the slider 39 and the second roller 310 to move in the same direction, thereby adjusting the vertical distance between the two second rollers 310 and the first roller 43 to accommodate warp-knitted fabrics of different thicknesses and provide stable tension. In the operation, when it is necessary to adjust the tension of the warp-knitted fabric, the first threaded sleeve 34 and the second threaded sleeve 35 are rotated to move them away from the movable seat 32. Then, by moving the movable seat 32 and the entire first pulling assembly 3 on the outside of the movable column 33, the two second rollers 310 of the first pulling assembly 3 are moved left and right for slight adjustment, so as to adjust the position angle between the second roller 310 and the first roller 43, which facilitates the adjustment of the tension of the warp-knitted fabric during traction. Subsequently, by adjusting the two second rollers 310 to move in the same direction, the first roller 43 can jointly squeeze the warp-knitted fabric, which is convenient for traction and transportation.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
