[0023] In one embodiment, the bottom of the support plate 407 is provided with a slider 408, and the top of the winding frame 1 is provided with a slide rail 102 that matches the slider 408. The slide rail 102 is perpendicular to the adjusting roller 405.

[0026] The working principle of this utility model:

[0027] Refer to the instruction manual appendix Figures 1-4 This utility model comprises a winding assembly 2, a guide roller assembly 3, an adjusting roller assembly 4, a roller frame 401, a first swing arm 402, a second swing arm 404, and an adjusting roller 405. The winding frame 1 provides overall support for the winding assembly 2, the guide roller assembly 3, and the adjusting roller assembly 4. The guide roller assembly 3 provides auxiliary guidance to the winding material before the winding assembly 2. The winding assembly 2 winds up the material. The adjusting roller assembly 4 provides automatic adjustment assistance to the material outside the winding assembly 2, resulting in a tighter and more stable winding. The roller frame 401 provides rotational support for the first swing arm 402, which in turn provides rotational support for the second swing arm 404. The second swing arm 404 provides rotational support for the adjusting roller 405. The adjusting roller 405 makes rolling contact with the surface of the material on the winding assembly 2. The support shaft 406 provides rotational support for the second swing arm 404. 4. The second swing arm 404 can rotate along the support shaft 406. The torsion spring provides elastic torsional support along the support shaft 406. When the second swing arm 404 rotates along the support shaft 406, the torsion spring provides elastic torsional support, which can effectively achieve elastic support for the second swing arm 404. When the adjusting roller 405 contacts and rolls with the surface of the roll material, it can automatically adjust with the change of the roll diameter during roll winding. The operation is convenient and quick. The adjusting roller 405 always rolls in close contact with the surface of the roll material, which can effectively ensure the tightness and stability of the roll winding. Moreover, the two sets of adjusting rollers 405 distributed vertically can provide rolling assistance to the roll material at the upper and lower positions during roll winding, which can further improve the tightness and stability of the roll winding. At the same time, the adjusting roller 405 directly rolls and presses the surface of the roll material, which can effectively ensure and improve the tightness and stability of the roll winding, and can effectively avoid damage caused by increased force on the surface of the roll material.

[0028] The telescopic movement of cylinder 403 can drive one end of the first swing arm 402 to swing, allowing the second swing arm 404 at the other end of the first swing arm 402 to swing as a whole. This can further improve the adjustment range of the adjusting roller 405 on the second swing arm 404, making the adjusting roller 405 adaptable to a wider range of the winding diameter of the coil material during automatic adjustment. The support plate 407 supports the bottom of the roller frame 401. The telescopic adjustment of hydraulic cylinder 101 can effectively drive the support plate 407 to perform horizontal displacement adjustment, thereby adjusting the horizontal displacement of the roller frame 401. This achieves overall horizontal displacement adjustment of the first swing arm 402, the second swing arm 404, and the adjusting roller 405, further improving the adjustment range of the adjusting roller 405 on the second swing arm 404, making the adjusting roller 405 adaptable to a wider range of the winding diameter of the coil material during automatic adjustment.
