[0023] refer to Figure 1-2As shown, an embodiment of the present utility model is:

[0024] A steam seal sheet rolling device includes a base 1, a gear box 2 is provided on the base 1, a driving shaft 3, an intermediate shaft 4, and a driven shaft 5 are provided in parallel on the gear box 2, the driving shaft 3 is connected to an external drive motor through a coupling, and the driving shaft 3 and the driven shaft 5 are both provided with an adjustable roller 6 at one end outside the gear box 2. The driving shaft 1, the intermediate shaft 4, and the driven shaft 5 are meshed through a gear 7 in the gear box 2, and a rolling shaft 8 is provided on the gear box 2 above the intermediate shaft 4. The rolling shaft 8 is provided with a rolling roller 9 adapted to the adjustable roller 6 at one end outside the gear box 2, and the gear box 2 is provided with a driving mechanism for driving the rolling shaft 8 to move up and down.

[0025] Specifically, the driving mechanism includes an adjusting screw 10 threadedly mounted on the upper end cover plate of the gear box 2, a lifting port 11 is provided on the side wall of the gear box 2, a guide rail 12 is provided on the side wall of the lifting port 11, a lifting block 13 is slidably mounted on the guide rail 12, the winding shaft 8 is rotatably connected to the lifting block 13, the adjusting screw 10 is rotatably connected to the lifting block 13, and a driving handwheel 14 is provided at the upper end of the adjusting screw 10.

[0026] Based on the thickness of the profile, the lifting screw 10 is adjusted to match the thickness of the profile with the spacing between the winding roller 9 and the adjustable roller 6. The profile is then fed through the gap between the winding roller 9 and the adjustable roller 6. Driven by an external motor, the rollers rotate accordingly, and the profile is rolled into a steam seal blank. Furthermore, the size of the winding roller 9 can be changed to produce steam seals of different specifications.

[0027] The adjustable roller 6 includes a first fixed roller 15, and the first fixed roller 15 is provided with at least one first adjusting roller group outwardly. The first adjusting roller group includes a first adjusting pad 16 and a first detachable roller 17 arranged in sequence, and the diameter of the first adjusting pad 16 is smaller than the diameters of the first fixed roller 15 and the first detachable roller 17;

[0028] The winding roller 9 includes a second fixed roller 18, and the second fixed roller 18 is provided with at least one second adjusting roller group outward. The second adjusting roller group includes a second adjusting pad 19 and a second detachable roller 20 arranged in sequence, and the diameter of the second adjusting pad 19 is smaller than the diameter of the second fixed roller 18 and the second detachable roller 20.

[0029] refer to Figure 1As shown, during implementation, the second adjustment pad and the first adjustment pad are kept the same width and located on the same vertical plane to ensure rolling quality. Adjustment pad widths on different vertical planes can be adjusted based on actual processing needs, such as the commonly used 1.6mm and 2.4mm. During assembly, the removable wheel assembly is secured with a threaded connection for easy replacement and maintenance.

[0030] To facilitate the installation and debugging of the equipment, a connecting block 21 extending into the interior of the gear box 2 is provided at the rear end of the lifting block 13 , and the connecting block 21 is rotatably connected to the adjusting screw 10 .

[0031] Furthermore, since the position of the winding roller 9 directly affects the bending radius of the steam sealing sheet, and its position is manually adjusted by the adjusting screw 10, in actual processing, the staff mainly relies on experience to judge the corresponding relationship between the position of the winding roller 9 and the bending radius of the steam sealing sheet. In order to ensure that the bending amplitude of the steam sealing sheets of the same batch is consistent, the staff needs to frequently debug, which affects work efficiency. Therefore, in this embodiment, a size calibration rod 22 is provided on the upper end cover plate behind the driving hand wheel 14, and the size calibration rod 22 is provided with a scale line. A slider 23 is slidably mounted on the size calibration rod 22, and a horizontal positioning rod 24 is provided on the side wall of the slider 23. The end of the horizontal positioning rod 24 is integrally formed with a U-shaped positioning groove, and the edge of the driving hand wheel 14 is located in the U-shaped positioning groove.

[0032] By placing the edge of the driving handwheel 14 in the U-shaped positioning groove, the slider will move accordingly on the size calibration rod 22 during the up and down movement of the driving handwheel. Combined with the reading at this time and the bending radius of the processed steam sealing piece, a corresponding relationship between the scale reading and the bending radius can be formed. The staff can know the bending radius of the rolled steam sealing piece by observing the position of the slider 23 on the size calibration rod 22, thereby reducing the staff's debugging frequency and improving processing efficiency.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
