[0023] like Figure 1-Figure 3 As shown, a winding device for magnetic powder tension braking of absorbing materials includes a frame 1 and a clamping assembly 3. High-temperature film reels 2 are obliquely arranged on both sides of the top of the frame 1. The clamping assembly 3 for facilitating clamping and winding of the absorbing material is installed in the middle of the frame 1. The clamping assembly 3 includes an absorbing material reel 301, a clamping slot 302, a connecting block 303, a torsion spring shaft 304 and a pressure plate 305. The top of the absorbing material reel 301 is provided with a clamping slot 302, and connecting blocks 303 are fixedly installed on both sides of the rear end of the clamping slot 302. A torsion spring shaft 304 is rotatably installed inside the connecting block 303, and a pressure plate 305 is fixedly installed on the end of the torsion spring shaft 304 away from the connecting block 303.

[0024] By adopting the above technical solution, one end of the wound material is placed into the slot 302, and then the rotational elastic force generated by the torsion spring shaft 304 rotates the pressure plate 305 counterclockwise with the connecting block 303 as the center, and the material inside the slot 302 is tightly clamped and fixed to prevent the material from sliding during winding, which affects the winding effect.

[0025] like Figure 4 As shown, the docking hole 4 is arranged in a "square" shape as a whole, and a transmission shaft 5 is inserted into the interior of the docking hole 4.

[0026] By adopting the above technical solution, the transmission shaft 5 provides power for the rotation of the wave-absorbing material reel 301 .

[0027] Furthermore, the end of the transmission shaft 5 is connected to a cycloid reducer 6 , and the bottom of the cycloid reducer 6 is fixed to the frame 1 .

[0028] By adopting the above technical solution, the cycloid pinwheel reducer 6 provides power for the winding drum.

[0029] Furthermore, a slide groove 7 is longitudinally opened on the left side of the frame 1 , and a fixing seat 8 is fixedly installed on the top of the inner wall of the slide groove 7 .

[0034] Working principle: When using the winding device for the absorbing material with magnetic powder tension braking, firstly, the absorbing material is physically passed around the support wheel 12 and wound onto the corresponding absorbing material winding 301.

[0035] Example 1: Place one end of the wound material into the slot 302, and then rotate the pressure plate 305 counterclockwise with the connecting block 303 as the center through the rotational elastic force generated by the torsion spring shaft 304, and tightly clamp the material inside the slot 302 to prevent the material from sliding when it is wound.

[0036] Embodiment 2: The spring 10 pushes the connecting seat 11 to separate from the fixed seat 8, and the connecting seat 11 pushes the supporting wheel 12 to apply thrust to the material passing through its bottom, and keeps the passing material in a straight state at all times, which has helped the wound material to remain straight and reduce wrinkles caused by loose materials. This is the working principle of the winding device for absorbing materials using magnetic powder tension braking.
