[0023] Reference Figures 1 to 5This utility model provides a method for easily fixing fireproof cotton strips: it includes a cotton strip roll 1, a fixing post 2, and a telescopic cylinder 3. The fixing post 2 and the telescopic cylinder 3 are respectively inserted into the interior of both ends of the cotton strip roll 1.

[0024] To fix fireproof cotton strips of different widths, a threaded rod 4 is rotatably connected to one end of the fixing post 2, and a rotating plate 5 is fixedly installed at the end of the threaded rod 4 away from the fixing post 2.

A limiting block 8 is fixedly installed on the outer wall of the fixed cylinder 7 away from the fixing post 2, and a limiting groove that matches the limiting block 8 is opened on the inner wall of the telescopic cylinder 3.

[0025] By setting up cotton roll 1, fixing post 2, telescopic cylinder 3, threaded rod 4, rotating plate 5, connecting cylinder 6, fixing cylinder 7, limiting block 8, sliding sleeve 9, slider 10, fixing bolt 11, rotating sleeve 12, limiting bolt 13, fixing frame 14, pressure plate 15, guide frame 16, screw rod 17, and rotating block 18, the function of pressing and fixing the remaining cotton roll 1 after use is realized.

At the same time, the two fixing frames 14 can be rotated by rotating sleeve 12, thereby improving the fixing accuracy of cotton roll 1. The fixing process is convenient and simple, saving time and effort, and improving the ease of use of fireproof cotton strips.

[0026] A pressing assembly is provided on the lower surface of the pressure plate 15. The pressing assembly includes a pressing block 19, which is located on the lower surface of the pressure plate 15. A rubber pad 20 is fixedly installed on the arc-shaped inner wall of the pressing block 19. A locking block 21 is fixedly installed on the lower surface of the pressure plate 15. A locking groove 22 is opened on the upper surface of the pressing block 19. Both the locking block 21 and the locking groove 22 are T-shaped. The locking block 21 and the inner wall of the locking groove 22 are slidably connected. A mounting bracket 23 is fixedly installed on the upper surface of the pressure plate 19. The mounting bracket 23 is sleeved on the outer surface of the pressure plate 15. A mounting bolt 24 is threadedly connected to the outer surface of the mounting bracket 23. The mounting bolt 24 penetrates the outer surface of the mounting bracket 23. A mounting hole for insertion of the mounting bolt 24 is opened through the upper surface of the pressure plate 15.

[0027] By setting up the pressure block 19, rubber pad 20, locking block 21, locking groove 22, mounting bracket 23 and mounting bolt 24, the function of improving the fixing effect of the tampon roll 1 is realized. By installing the pressure block 19 with the arc-shaped bottom surface to be in contact with the outer ring of the tampon roll 1, the fixing area of ​​the tampon roll 1 is increased. At the same time, the rubber pad 20 is used to prevent the tampon roll 1 from slipping. On the original basis, the fixing effect of the tampon roll 1 is further improved.

[0028] Working principle: Before fixing the fireproof cotton strip, first bring the pressure block 19 close to the pressure plate 15, so that the locking block 21 is aligned with the locking groove 22 and the mounting bracket 23 is aligned with the pressure plate 15. Then move the pressure block 19 so that it slides against the lower surface of the pressure plate 15 and the locking block 21 slides inside the locking groove 22. When the locking block 21 slides to the end of the locking groove 22, the mounting bracket 23 is fitted onto the outer surface of the pressure plate 15. Then tighten the mounting bolt 24 so that the mounting bolt 24 extends towards the mounting bracket 23. When the mounting bolt 24 penetrates the outer surface of the mounting bracket 23 and is screwed into the mounting hole, the mounting bracket 23 is fixed and the pressure block 19 is fixed at the same time, completing the installation of the pressure block 19. Repeat the above operation to install another pressure block 19 onto another pressure plate 15; reverse the above operation to disassemble the pressure block 19 for easy replacement.

[0029] When fixing the fireproof cotton strip, first adjust the distance between the telescopic cylinder 3 and the fixing post 2 according to the width of the cotton strip roll 1. Rotate the rotating plate 5, which drives the threaded rod 4 to rotate. During the rotation of the threaded rod 4, the threaded groove drives the connecting cylinder 6 to move, thereby causing the telescopic cylinder 3 to move on the outer surface of the fixing cylinder 7. Under the action of the limiting block 8, the connecting cylinder 6 slides along the outer surface of the threaded rod 4, the telescopic cylinder 3 slides on the outer surface of the fixing cylinder 7, and the limiting block 8 slides inside the limiting groove. When the telescopic cylinder 3 and the fixing post 2 reach a suitable distance, stop rotating the rotating plate 5 to fix the telescopic cylinder 3. Then, put the cotton strip roll 1 onto the outer surface of the fixing post 2 and the telescopic cylinder 3. Next, bring the sliding sleeve 9 close to the telescopic cylinder 3 so that the slider 10 is aligned with the sliding groove. Move the sliding sleeve 9 so that the sliding sleeve 9 moves in the telescopic groove. The outer surface of the cylinder 3 slides, and the slider 10 slides inside the slide groove. When the sliding sleeve 9 is fitted onto the outer surface of the telescopic cylinder 3, the fixing bolt 11 is rotated so that the fixing bolt 11 penetrates the outer surface of the sliding sleeve 9 and is screwed into the outer surface of the telescopic cylinder 3 to fix the sliding sleeve 9. At this time, the cotton roll 1 is between the two fixing frames 14. Then, the rotating block 18 on the two fixing frames 14 is rotated, which drives the two lead screws 17 to rotate. When the lead screws 17 rotate, the lead screws 17 extend towards the fixing frames 14, thereby driving the pressure plate 15 to move, so that the guide frame 16 slides inside the guide groove. During the movement of the pressure plate 15, the pressure block 19 moves towards the direction of the cotton roll 1. When the pressure block 19 contacts the cotton roll 1, it presses and fixes the cotton roll 1. The above operation is reversed to release the fixation of the cotton roll 1.

[0030] During the process of fixing the cotton roll 1, first rotate the limiting bolt 13 so that the limiting bolt 13 extends away from the rotating sleeve 12. After the limiting bolt 13 is unscrewed from the inside of the limiting hole, the fixing of the rotating sleeve 12 is released. At this time, pull the fixing frame 14, which will drive the two rotating sleeves 12 to rotate on the outer surfaces of the fixing column 2 and the sliding sleeve 9 respectively. At the same time, it will drive the two sets of pressure plates 15 and pressure blocks 19 to move. After the pressure plates 15 and pressure blocks 19 move to the break point of the fireproof cotton strip, rotate the limiting bolt 13 in the opposite direction so that the limiting bolt 13 is screwed back into the inside of the limiting hole, fixing the rotating sleeve 12 and the fixing frame 14. At this time, the break point of the cotton roll 1 can be accurately fixed.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
