[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0028] like Figures 1 to 7 As shown, the calender roll inner hole cleaning device includes a base 1, a brush seat 2 on the base 1, a fixed shaft 3 on the brush seat 2, a brush head 4 at the end of the fixed shaft 3, and an angle adjustment mechanism connected to the brush head 4.

[0029] like Figures 5 to 7As shown, the angle adjustment mechanism includes a spindle 41, which is located inside a fixed shaft 3. The end of the spindle 41 extends out of the fixed shaft 3 and is hinged to a connecting rod 42. A spherical bearing 43 is provided at the end of the fixed shaft 3, and the connecting rod 42 passes through the spherical bearing 43. A brush head 4 is located at the end of the connecting rod 42. A fixing ring 31 is fitted on the fixed shaft 3. A first fixing seat 35 and a second fixing seat 36 are fixedly connected to both sides of the fixing ring 31 on the fixed shaft 3. A waist groove 33 is provided on the fixed shaft 3, and a pin 32 is provided on the fixing ring 31. The pin 32 passes through the fixing ring 31, the spindle 41, and the waist groove 33. The outer ring of the spherical bearing 43 is fixed to the fixed shaft 3. The connecting rod 42 passes through the inner ring of the spherical bearing 43. The extension and retraction of the spindle 41 drives the connecting rod 42 to rotate. Due to the aforementioned spherical bearing 43, the angle of the brush head 4 located at the end of the connecting rod 42 can be adjusted. The spindle 41 is connected to the fixed ring 31 through the pin 32. Therefore, only the movement of the fixed ring 31 needs to be controlled to drive the spindle 41 to move axially, thereby achieving the purpose of adjusting the angle of the brush head 4. This ensures that the brush head 4 can contact the inner wall of the calender roll's inner hole and also meets the cleaning needs of calender rolls with different inner diameters or the same type of calender rolls (large inner hole, small spindle head), making it widely applicable. The maximum movement distance of the fixed ring 31 is the length of the waist groove 33. A self-lubricating bearing 34 is provided between the inner side of the fixed shaft 3 end and the spindle 41 to reduce resistance when the spindle 41 is extended and retracted.

[0030] like Figure 6 and Figure 7As shown, a first retaining ring 352 and a first spring 353 are provided between the fixing ring 31 and the first fixing seat 35, and a second retaining ring 362 and a second spring 363 are provided between the fixing ring 31 and the second fixing seat 36. The two sides of the fixing ring 31 contact the first spring 353 and the second spring 363 respectively. A first adjusting bolt 351 is threadedly connected to the first fixing seat 35, and a second adjusting bolt 361 is threadedly connected to the second fixing seat 36. The first adjusting bolt 351 and the second adjusting bolt 361 are arranged opposite to each other. The end of the first adjusting bolt 351 contacts the first retaining ring 352, and the first retaining ring 352 presses against the first spring 353. The end of the second adjusting bolt 361 contacts the second retaining ring 362, and the second retaining ring 362 presses against the second spring 363. The first retaining ring 352, the first spring 353, the second retaining ring 362, and the second spring 363 are all sleeved on the fixed shaft 3. To ensure that the mandrel 41 is fixed in position relative to the fixed shaft 3 after extension and retraction, and to ensure the reliable cleaning effect of the brush head 4, the first adjusting bolt 351 is turned or loosened to press against the first retaining ring 352, thereby compressing or restoring the length of the first spring 353. The second adjusting bolt 361 controls the position of the second retaining ring 362 to adjust the length of the second spring 363. The first spring 353 and the second spring 363 adjust the compression length accordingly to change the position of the fixed ring 31, thereby realizing the movement of the fixed ring 31 on the fixed shaft 3. The purpose of the fixed ring 31 is changed by adjusting the bolt according to the size of the inner hole of the calender roller to be cleaned, so that the unfolding angle of the brush head 4 is adapted to the inner hole diameter of the calender roller. When the two springs squeeze the fixed ring 31 and reach force balance, the position of the fixed ring 31 is fixed, and the angle adjustment of the brush head 4 is completed. Because the pin 32 passes through the spindle 41 and the waist groove 33, the relative position of the spindle 41 and the fixed shaft 3 is fixed. The fixed shaft 3 and the spindle 41 will not rotate relative to each other, and the spindle 41 will not have axial displacement within the fixed shaft 3. During the cleaning process of the brush head 4, the brush head 4 will not shrink due to the resistance of scale, resulting in poor cleaning effect. It can also prevent the connecting rod 42 from becoming loose or breaking.

[0031] like Figures 1 to 4As shown, the brush holder 2 includes a central support 21 and end supports 22, with the end supports 22 located on both sides of the central support 21. A lead screw 11 is mounted on the machine base 1, and a lead screw nut 24 is mounted at the bottom of the central support 21, cooperating with the lead screw 11. A guide rail 13 is mounted on the machine base 1, and a slider 25 is mounted at the bottom of the end supports 22, cooperating with the guide rail 13. The guide rails 13 are arranged in pairs. This structure, with the central support 21 positioned in the middle of the brush holder 2, improves the stability of the components on the brush holder 2, thereby maintaining the horizontal orientation of the fixed shaft 3. The central support 21 achieves linear movement of the brush holder 2 through the lead screw 11 transmission mechanism, while the end supports 22, through the cooperation of the slider 25 and the guide rail 13, provide movement and support for the brush holder 2. The paired arrangement improves the guiding accuracy of the brush holder 2. The use of the lead screw 11 transmission mechanism to control the movement of the brush head 4 within the inner hole of the calender roll ensures stable movement without significant impact, preventing damage to the inner hole of the calender roll.

[0032] like Figure 2 As shown, the brush holder 2 is equipped with bearing seats 23, and the fixed shaft 3 is mounted on the bearing seats 23. There are two bearing seats 23. The brush holder 2 is also equipped with a motor 26. The output end of the motor 26 is equipped with a driving gear 27, and the end of the fixed shaft 3 is fixedly connected to a driven gear 28, which meshes with the driving gear 27. The rotation of the fixed shaft 3 is powered by the motor 26. The motor 26 drives the fixed shaft 3 to rotate through a pair of gears, which in turn drives the brush head 4 to rotate, achieving uniform cleaning of the inner wall of the calender roll. The two bearing seats 23 facilitate the rotation of the fixed shaft 3 and help maintain its horizontal stability.

[0033] like Figure 5 As shown, the brush heads 4 are symmetrically arranged about the axis of the fixed shaft 3. Using multiple brush heads 4 can improve cleaning efficiency.

[0034] like Figure 6 As shown, the first adjusting bolt 351 and the second adjusting bolt 361 are both equally spaced along the circumference. Multiple adjusting bolts ensure that the retaining ring is evenly stressed, preventing skewing and ensuring the stability of the fixed ring 31 under stress.

[0035] like Figure 1 As shown, a handwheel 12 is fixedly connected to the end of the lead screw 11. The handwheel 12 facilitates the operator's control of the movement and feed of the brush head 4, making manual operation easier and reducing the complexity of the equipment.

[0036] like Figure 1 As shown, the base 1 is equipped with rollers 14 at its bottom. The rollers 14 facilitate the movement of the entire device and improve ease of use.

[0037] like Figure 3 and Figure 4As shown, a mounting base 5 is provided on one side of the machine base 1, and the calendering roll is mounted on the mounting base 5. The calendering roll is set horizontally, and the fixed shaft 3 is on the same axis as the calendering roll. The mounting base 5 is provided with a mounting mechanism to fix the calendering roll in a stable horizontal position. When the fixed shaft 3 is collinear with the calendering roll, the device can be started. The position of the brush holder 2 is adjusted, and the fixed shaft 3 and the brush head 4 are inserted into the inner hole of the calendering roll to carry out the cleaning process.

[0038] Traditional methods for cleaning inner holes include manual polishing and grinding, or soaking in chemical agents, which are effective. The brush head 4 in this application is rotatable, has an adjustable unfolding angle, and can move axially, providing a complete cleaning effect on the inner hole of the calender roll. It is suitable not only for roller-type workpieces with uniform inner diameter, but also for roller-type workpieces with shaft head inner holes smaller than the roller body and small shaft head size, which are not suitable for manual operation or cannot be soaked in chemicals.

[0039] The operation of the calender roll inner hole cleaning device is as follows: Place the calender roll to be cleaned on the mounting base 5 and fix it in place, so that the axis of the calender roll is collinear with the axis of the fixed shaft 3. Adjust the unfolding angle of the brush head 4 according to the size of the inner hole diameter of the calender roll. Specifically, the adjusting bolts and retaining rings on the fixed shaft 3 apply pressure to the springs. The position of the fixing ring 31 on the fixed shaft 3 is adjusted by the compression of the two springs. The fixing ring 31 drives the mandrel 41 to extend and retract within the fixed shaft 3 through the pin 32. The extension and retraction of the mandrel 41 adjusts the unfolding angle of the brush head through the connecting rod 42 and the spherical bearing 43. Then, the motor 26 starts and drives the brush head 4 on the fixed shaft 3 to rotate through the gear. The operator turns the handwheel 12, and the brush seat 2 moves along the guide rail 13 under the transmission of the screw 11 transmission module, so that the fixed shaft 3 and the brush head 4 extend into the inner hole of the calender roll. Through the rotation of the fixed shaft 3 and the linear movement of the brush seat 2, the brush head 4 can achieve uniform and effective cleaning of the inner hole of the calender roll.

[0040] This calender roll inner hole cleaning device uses a brush head 4 to clean the scale in the inner hole of the calender roll. The brush head 4 is connected to a mechanism that can control its unfolding angle, which can be adjusted according to the size of the inner hole of the calender roll to meet the cleaning needs of inner holes of multi-diameter or multi-type roll workpieces. It is equipped with a movable brush seat 2 and a motor 26 that can drive the brush head 4 to rotate, so as to achieve a thorough cleaning of the inner hole of the calender roll. Compared with the existing technology that uses circulating water or descaling agents, it has a more reliable cleaning effect.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
