[0002] The winding device of the existing warp knitting machine is shown in the Chinese utility model patent "Authorization Announcement Number: CN219906317U; Authorization Announcement Date: October 27, 2023; Name: A Winding Device for a Warp Knitting Machine": Its winding device includes a mounting frame (equivalent to left and right brackets) and two transmission rollers (equivalent to an active roller and a driven roller) and a winding roller arranged on the mounting frame. The two transmission rollers are rotatably mounted on the mounting frame in a fixed point form, and the winding roller is installed in a placement hole (equivalent to an inclined sliding strip opening) of the mounting frame. The placement hole is a strip opening with an opening obliquely facing upward. During use, as the thickness of the fabric wrapped by the winding roller increases, the winding drum will move obliquely upward along the placement hole, which will inevitably weaken the driving ability of the two transmission rollers on the winding roller, and there are defects.

[0031] Embodiment 1:

[0032] like Figures 1 to 3As shown, a winding mechanism of a warp knitting machine includes a left bracket 1, a right bracket 2, and a driving roller 3 and a driven roller 4 arranged between the left bracket 1 and the right bracket 2. The driving roller 3 is rotatably installed on the left bracket 1 and the right bracket 2 in a fixed-point form. The driven roller 4 is slidably arranged in the horizontal bar holes 10 of the left bracket 1 and the right bracket 2. The driven roller 4 can rotate freely in the horizontal bar holes 10. The tops of the left bracket 1 and the right bracket 2 are correspondingly provided with oblique sliding strip openings 6 for accommodating the winding roller 5. The oblique sliding strip openings 6 are inclined in the direction away from the driving roller 3 and the openings of the oblique sliding strip openings 6 face upward. The outer sides of the left bracket 1 and the right bracket 2 are provided with adjustment and support devices for adjusting and supporting the driven roller 4 and the winding roller 5. The left bracket 1 and the right bracket 2 are vertical plates, and the end rotating shafts of the winding roller 5 are respectively provided with positioning baffles to prevent the winding roller 5 from axially jumping. The top of the left bracket 1 and the right bracket 2 are also equipped with a pressure roller 7 for the winding roller 5. The pressure roller 7 is hinged on the outer bracket 8, and the outer bracket 8 is fixed on the outer side of the left and right brackets. The rotation of the active roller 3 is driven by a driving motor 9. The active roller 3 and the driven roller 4 are connected by a toothed chain. When the driven roller 4 is farthest away from the active roller 3, the toothed chain section on the lower side of the active roller 3 and the driven roller 4 is in a relaxed state or just in a tensioned state.

[0033] The adjusting support device includes an adjusting hydraulic cylinder 13, a driven roller adjusting rod 14 and a winding roller support 15 respectively hinged on the outer end of the telescopic rod of the adjusting hydraulic cylinder 13. The adjusting hydraulic cylinder 13 is located on the bisector of the angle between the horizontal bar hole 10 and the inclined sliding bar mouth 6. The telescopic rod of the adjusting hydraulic cylinder 13 faces the side where the horizontal bar hole 10 and the inclined sliding bar mouth 6 gradually approach each other. The lower end of the driven roller adjusting rod 14 is hinged with a sleeve 12, which is slidably arranged in a horizontal slideway 11 on the upper side of the horizontal bar hole 10. The sleeve 12 is sleeved on the end shaft of the driven roller 4, and the driven roller 4 can rotate freely in the sleeve 12. The upper end of the winding roller support 15 is provided with a buckle for rotatably connecting with the end shaft of the winding roller. The winding roller support 15 is an axial elastic support, which includes a large cylinder body and a small cylinder body that are sleeved with each other, and a support spring arranged between the sleeve body and the small cylinder body.

[0034] Principle of use: put the winding roller 5 into the opening of the inclined slide 6 and make it contact with the active roller 3 and the driven roller 4, evenly wind the cloth to be wound on the winding roller 5, then place the pressure roller 7 on the winding roller 5 to press the wound cloth, start the driving motor 9, and the numerous rollers 3 and the driven roller 4 drive the winding roller 5 to rotate to achieve the winding of the cloth. As the cloth wound by the winding roller 5 increases, the outer diameter of the winding roller 5 becomes larger and larger, and the hydraulic cylinder 13 is adjusted to pull back the telescopic rod, and the driven roller 4 is pulled outward while providing an upward push force for the winding roller 5, so as to keep the active roller 3 and the driven roller 4 to support the winding roller 5 well, which can effectively ensure that the active roller 3 and the driven roller 4 drive the winding roller 5 stably. At the same time, the elastic winding roller support 15 can provide support for the winding roller 5 on the one hand, and limit it to a certain extent to avoid jumping, etc., which can further ensure that the active roller 3 and the driven roller 4 drive the winding roller 5 stably.
