Through the setting of a cleaning component, a dual-axis motor drives the rotating shaft to rotate. Under the rotation of the rotating shaft, the brush plate cleans the debris and impurities on the surface of the material. The gears rotate while the rotating shaft rotates, so that the gears drive the dual-axis motor to move in a straight line to one side, and then the water tank moves, so that the water tank drives the surface of the material to be cleaned in all directions. Through the cleaning action of the cleaning component, the surface of the material can be fully cleaned, while ensuring the cleaning effect of the surface of the material and improving the cleaning quality.

[0023] It should be noted here that: "the three supporting rollers are rotatably connected between the two double-sided racks 10 and the two groups of single-sided racks 13", and the meaning of group here is: the two single-sided racks 13 at the same setting position in the two protective members 3 are regarded as a group, the control component belongs to the existing mature technology, it can transmit electrical signals to each electric push rod 1 6 and electric push rod 2 26, so as to drive them to work, the cleaning effect of the cleaning brush assembly is consistent with the effect of the cleaning assembly in the comparative document mentioned in the background technology, and the cleaning effect of the cleaning brush assembly in the comparative document mentioned in the background technology is consistent with the cleaning effect of the cleaning brush ... Figure 2 and 7 This state corresponds to the initial state of the device of the present invention, that is, the state in which the leather has been installed but the operation has not started. In this state, the angle formed by the three support rollers is set to α, and α is an obtuse angle. When the cleaning operation starts, the cleaning brush assembly will clean the surface of the leather. After cleaning for a certain period of time, the control assembly will transmit an electrical signal to each electric push rod 1 6 and electric push rod 2 26. The output shaft of the electric push rod 2 26 extends and comes into contact with the leather, and then the leather is tightly pressed, similar to fixing the leather. The output shaft of the electric push rod 1 6 extends, and under the connection of the connecting rod 1 5, the connecting block 4 and the slider 1 11, the height of the double-sided racks 10 at both ends is simultaneously increased, thereby increasing the height of the support roller located in the middle position. It will pull the leather upwards, through the gear 12 and the two single-sided racks 13, which are affected by the meshing relationship with the double-sided rack 10, the upward movement of the double-sided rack 10 is fed back to the two single-sided racks 13, and the two single-sided racks 13 are displaced obliquely downward, thereby reducing the height of the other two supporting rollers. At this time, the two rollers lose contact with the leather. Since the contact part between the top of the leather and the supporting roller in the middle position is propped up, that is, α is reduced but still remains obtuse, the groove here becomes larger, and the dirt hidden in the groove is revealed, which is more conducive to subsequent comprehensive cleaning. The pre-pressing of the electric push rod 26 is to prevent the position dislocation caused when the top of the leather is propped up. The initial state of the pressing block 18 can be referred to the attached manual. Figure 6 , the rubber pad 19 at its bottom end presses the leather surface earlier than the rubber pad 19 on the pressing block 22, but in the above process, the position of the pressing block 18 is raised together with the cross block 17, and through the tooth column 25 and the two tooth plates, the upward movement of the pressing block 18 causes the pressing block 22 to move downward. It should be noted here that: the width of the pressing block 22 is greater than that of the pressing block 18, and the position where the pressing blocks 18 and 22 produce compression is defined as the pressing point, then the downward movement of the pressing block 22 is equivalent to the position of the pressing point being closer to the middle position of the leather, then the distance between the leather and the support platform 27 is reduced, and the leather is closer to the support rollers on both sides, which is convenient for subsequent cleaning operations. In addition, the lifting of the position of the pressing block 18 makes the part originally blocked by the pressing block 18 appear, which is beneficial for the cleaning brush assembly to complete a full range of cleaning of the leather later.

[0024] For example 3, please refer to Figures 1 to 11 On the basis of the second embodiment, the features of the mechanisms arranged on the tops of the two support platforms 27 are completely the same. An adjustment block 30 and an adjustment plate 32 are hingedly arranged on the top of the support platform 27. Through openings 29 are provided on the outer walls of both sides of the support platform 27. A connecting rod 28 is fixedly connected to the middle position of the outer wall of the connecting rod 1 5. The connecting rod 28 passes through the interior of the base block 2. Auxiliary grooves 31 with elliptical cross sections are provided on the outer walls of both sides of the adjustment block 30. One end of the connecting rod 28 is slidably connected to the inner wall of the auxiliary groove 31. The top of the adjustment block 30 is provided with a There is a slideway that is in a sliding connection with an adjustment plate 32. The length of the adjustment plate 32 is greater than the slideway. A rotating member 33 is fixedly connected to one end of the adjustment plate 32. A rectangular groove is provided at one end of the adjustment block 30. The interior of the rectangular groove is connected to the slideway and the external space. Adaptation grooves 37 are provided on the inner walls on both sides of the rectangular groove. A square slider 36 is slidably connected to the interior of the adaptation groove 37. A compensation plate 34 is fixedly connected between the two square sliders 36. A through-type inclined groove 35 is provided at one end of the compensation plate 34. The rotating member 33 is rotatably connected between the inner walls on both sides of the inclined groove 35.

[0025] It should be noted here that in the initial state, you can observe the Fig. 9 The top surfaces of the adjusting plate 32, the adjusting block 30 and the compensating plate 34 are flush with the supporting platform 27 and form a complete and regular geometric body with the supporting platform 27. In the process of raising the position of the connecting rod 1 5, the connecting rod 28 is displaced together and gradually disengaged from the inside of the opening 29. Through the auxiliary groove 31 provided on the outer wall of the adjusting block 30, the connecting rod 28 slides along the inside of the auxiliary groove 31, thereby causing the adjusting block 30 to flip along the hinge between itself and the supporting platform 27. At the same time, the adjusting plate 32 is also rotated along the hinge between itself and the supporting platform 27. The adjusting block 30 is turned over from the support platform 27 and the contact relationship with the leather is re-established. The compensation plate 34 is pushed out of the rectangular groove by the adjusting plate 32 and the rotating part 33 to further support the leather, which is equivalent to supporting the leather instead of the supporting rollers on both sides, thereby adapting to the entire adjustment process and facilitating the cleaning of dirt hidden in the grooves of the leather, thereby improving the cleaning effect.

[0026] In actual use, when the cleaning operation begins, the cleaning brush assembly will clean the surface of the leather. After cleaning for a certain period of time, the control assembly will then transmit electrical signals to each electric push rod 1 6 and electric push rod 2 26. The output shaft of the electric push rod 2 26 will extend and come into contact with the leather, and then the leather will be tightly pressed, similar to fixing the leather. The output shaft of the electric push rod 1 6 will extend, and under the connection of the connecting rod 1 5, the connecting block 4 and the slider 1 1 , the heights of the double-sided racks 10 at both ends will be simultaneously increased, thereby increasing the height of the support roller shaft in the middle position, which will pull the leather upward, and through the provided gear 12 and the two single-sided racks 13, affected by their meshing relationship with the double-sided rack 10, the upward movement of the double-sided rack 10 is fed back to the two single-sided racks 13, and the two single-sided racks 13 are displaced in an oblique downward direction, thereby reducing the height of the other two support roller shafts. At this time, the two roller shafts lose contact with the leather. Since the contact portion between the top of the leather and the support roller shaft in the middle position is propped up, that is, α is reduced but still forms an obtuse angle, then here The grooves become larger, and the dirt hidden in the grooves can be revealed, which is more conducive to subsequent comprehensive cleaning. In the process of raising the position of the connecting rod 1 5, the connecting rod 28 is displaced together and gradually disengaged from the inside of the opening 29. Through the auxiliary groove 31 opened on the outer wall of the adjusting block 30, the connecting rod 28 slides along the inside of the auxiliary groove 31, so that the adjusting block 30 is flipped along the hinge between itself and the support platform 27. At the same time, the adjusting plate 32 is also flipped along the hinge between itself and the support platform 27, and pushes the compensation plate 34 to disengage from the rectangular groove. Through the above-mentioned components, due to the reduction of the top α of the leather, the gap between the leather and the supporting rollers on both sides is filled by the adjusting block 30 and the compensation plate 34, and the adjusting block 30 is flipped out of the support platform 27 and re-contacts with the leather. The compensation plate 34 is pushed out of the rectangular groove by the adjusting plate 32 and the rotating member 33, and the leather is further supported, which is equivalent to replacing the supporting rollers on both sides to support the leather, thereby adapting to the entire adjustment process, which is conducive to cleaning the dirt hidden in the leather grooves, thereby improving the cleaning effect.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
