[0019] Specifically, the arc-resistant layer is made of methyl vinyl silicone rubber to improve the arc-resistant performance of the fireproof belt.

[0020] Specifically, a rotation groove 4 is opened on the opposite side of the two side plates 32, and the winding shaft 2 is rotatably arranged in the rotation groove 4. A threaded hole 5 connected to the rotation groove 4 is opened on the outer wall of one side plate 32. The diameter of the threaded hole 5 is larger than the diameter of the rotation groove 4. A cover plate 6 is threadedly connected to the threaded hole 5. By unscrewing the cover plate 6, the winding shaft 2 can be pulled out of the rotation groove 4. When installing a new fire belt, the fire belt can be rolled between the two side plates 32. After the winding shaft 2 passes through the rotation groove 4 and passes through the center of the fire belt roll until it contacts the rotation groove 4 on the other side, the cover plate 6 is screwed on the threaded hole 5 for limiting the position, so that the fixing frame 3 can be reused after the fire belt is used up.

[0021] Specifically, a slot 7 is provided at one end of the winding shaft 2 near the threaded hole 5, and an insert block 8 rotatably connected to the slot 7 is fixedly provided on the cover plate 6 to improve the installation stability of the winding shaft 2. A protrusion 9 is fixedly provided on the side of the cover plate 6 away from the insert block 8, and the cover plate 6 can be rotated conveniently through the protrusion 9.

[0022] Specifically, a lower cutting blade groove 10 is opened on the top frame 12, and the lower cutting blade 11 is arranged in the lower cutting blade groove 10 and does not protrude from the lower cutting blade groove 10, so that the fireproof belt 1 can slide along the surface of the main frame 31, avoiding the lower cutting blade 11 from scratching the fireproof belt when the fireproof belt 1 is still moving and pulled out.

[0023] Specifically, a threaded groove 17 is provided at one end of the moving block 16 located in the moving block groove 15, and a screw 18 is threadedly connected to the threaded groove 17. The screw 18 passes through the top frame 12 and is fixedly connected to the knob 19. Turning the knob 19 drives the screw 18 to rotate. Through the threaded connection between the screw 18 and the threaded groove 17, the moving block 16 moves in the moving block groove 15, and the moving block 16 drives the upper cutting piece 14 to move in the upper cutting piece groove 13, so that the upper cutting piece 14 and the lower cutting piece 11 cut the fireproof belt 1. A limit ring 20 is fixedly sleeved on the outer wall of the screw 18 to be rotatably connected to the top frame 12. The limit ring 20 is limited to prevent the screw 18 from axial movement.

[0024] A specific application example of this embodiment is:

[0025] When the device is in use, when using the fireproof belt 1, the fireproof belt 1 is pulled out from the fireproof belt roll and passed around the top of the main frame 31. After the fireproof belt 1 reaches the required length, the knob 19 is turned to drive the screw 18 to rotate, and the screw 18 is threadedly connected with the threaded groove 17, so that the moving block 16 moves down in the moving block groove 15, and the moving block 16 drives the upper cutting piece 14 to move in the upper cutting piece groove 13, so that the sharp ends of the upper cutting piece 14 and the lower cutting piece 11 fit together to cut the fireproof belt 1, which is easy to operate and convenient for cutting. After the fireproof belt is used up, the cover plate 6 is unscrewed, and the winding shaft 2 can be pulled out from the rotation groove 4. When installing a new fireproof belt, the fireproof belt roll can be placed between the two side plates 32, and the winding shaft 2 is passed through the rotation groove 4 and through the center of the fireproof belt roll until it contacts the rotation groove 4 on the other side, and then the cover plate 6 is screwed on in the threaded hole 5 for limiting, so that the fixing frame 3 can be reused after the fireproof belt is used up to avoid material waste.
