[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0026] like Figure 1As shown, an embodiment of the utility model provides a cleaning device for cleaning a steel stamp 51 installed on a steel stamp seat 5, comprising: a mounting shaft 1, a brush roller 2, a first limit member 3 and a second limit member 4.
[0027] Specifically, the shaft 1 is installed along a first direction (such as Figure 1 The mounting shaft 1 extends in the X direction as shown, and one end of the mounting shaft 1 is connected to the steel stamp seat 5.
[0028] The brush roller 2 is sleeved on the mounting shaft 1 and can slide on the mounting shaft 1 along the first direction. The circumferential surface of the brush roller 2 is provided with bristles 21, and the bristles 21 are in contact with the circumferential surface of the steel stamp 51. The length of the brush roller 2 along the first direction is greater than the length of the steel stamp 51 along the first direction.
[0029] The first stopper 3 is disposed at one end of the brush roller 2 along the first direction. The first stopper 3 is used to block the brush roller 2 from moving along the side facing the first stopper 3 (such as Figure 1 Move in the X1 direction shown in FIG.
[0030] The second stopper 4 is disposed at the other end of the brush roller 2 along the first direction. The second stopper 4 is used to block the brush roller 2 from moving along the side facing the second stopper 4 (such as Figure 1 Move in the X2 direction shown in FIG.
[0031] The applicant has fully considered the problems that may arise when the cleaning device cleans the steel stamp 51. By setting the axial position of the brush roller 2 to be adjustable and limiting the axial position of the brush roller 2 using the first limit member 3 and the second limit member 4, the bristles 21 at different positions on the brush roller 2 can be brought into contact with the steel stamp 51 to clean the steel stamp 51, thereby making it possible for the bristles 21 at any position on the brush roller 2 to be fully utilized.
[0032] Specifically, when installing a new brush roller 2, firstly, the brush roller 2 is sleeved on the installation shaft 1, and the first limiter 3 and the second limiter 4 are used to limit the position of the brush roller 2 along the first direction, so that the bristles 21 on the brush roller 2 are in contact with the steel stamp 51. When the equipment is working, the steel stamp 51 rotates around its own axis, and the brush 21 rotates around the installation shaft 1 driven by the steel stamp 51, and cleans the circumferential surface of the steel stamp 51. When the bristles 21 on the brush roller 2 that are in contact with the steel stamp 51 are worn, the operator releases the limit lock of the brush roller 2 by the first limiter 3 and the second limiter 4, and then adjusts the position of the brush roller 21 along the first direction, so that the unworn bristles 21 on the brush roller 2 are in contact with the steel stamp 51. Subsequently, the operator uses the first limiter 3 and the second limiter 4 to limit the brush roller 2 again to prevent the brush roller 2 from moving along the installation shaft 1, so that the unworn bristles 21 clean the steel stamp 51. When the bristles 21 on the brush roller 2 that are in contact with the steel stamp 51 are worn again, the operator repeats the above operation until the bristles 21 on the entire brush roller 2 are all worn, and then replaces the brush roller 2.
[0033] Furthermore, the first stopper 3 and the second stopper 4 can both move along the first direction on the mounting shaft 1, and are used to adjust the position of the brush roller 2 along the first direction. When adjusting the position of the brush roller 2, the brush roller 2 is moved to a suitable position, and the first stopper 3 and the second stopper 4 also move with the brush roller 2, so that the unworn bristles 21 on the brush roller 2 are aligned with the steel stamp 51, and then the first stopper 3 and the second stopper 4 are fixed to the two ends of the brush roller 2, so that the position of the brush roller 2 can be adjusted.
[0034] The cleaning device of the utility model is configured such that the first limit member 3, the second limit member 4 and the brush roller 2 are all movable axially along the mounting shaft 1, and then the first limit member 3 and the second limit member 4 are used to limit the axial position of the brush roller 2 along the mounting shaft 1, thereby adjusting the relative position of the brush roller 2 and the steel stamp 51.
[0035] In specific implementation, the installation shaft 1 is a threaded shaft 11, and the second limiter 4 is an adjusting nut 41, which is located at the end of the brush roller 2 facing away from the steel stamp seat 5, and the adjusting nut 41 is threadedly connected to the threaded shaft 11. The adjusting nut 41 can limit the displacement of the brush roller 2 along the X2 direction.
[0036] The cleaning device of the utility model sets the installation shaft 1 as a threaded shaft 11 and the second limit member 4 as an adjusting nut 41, so that the adjusting nut 41 is threadedly connected to the threaded shaft 11. The position of the adjusting nut 41 on the threaded shaft 11 can be changed by rotating the adjusting nut 41, thereby changing the position of the brush roller 2 along the first direction, and the operation is simple.
[0037] Specifically, the first limit member 3 is a compression spring 31, which is sleeved on the mounting shaft 1 and located between the stamp seat 5 and the brush roller 2. The compression spring 31 can generate a thrust along the X2 direction on the brush roller 2 to limit the movement of the brush roller 2 along the X1 direction.
[0038] The utility model sets the first limiter 3 as a compression spring 31. When the position of the brush roller 2 needs to be adjusted, the brush roller 2 can be driven to move by adjusting the position of the adjustment nut 41. When the brush roller 2 moves along the X direction, the end of the compression spring 31 in contact with the brush roller 2 will automatically move with the brush roller 2 and continuously apply a thrust along the X2 direction to the brush roller 2. Therefore, there is no need to adjust the position of the first limiter 3, which is convenient for the operator to operate.
[0039] Furthermore, if Figure 2 and Figure 3 As shown, a sleeve 6 is provided between the threaded shaft 11 and the brush roller 2. The sleeve 6 is sleeved on the threaded shaft 11, and the brush roller 2 is sleeved on the outside of the sleeve 6. The two ends of the sleeve 6 are respectively in contact with the compression spring 31 and the adjusting nut 41.
[0040] Exemplarily, one end of the sleeve 6 close to the compression spring 31 is provided with a limiting ring 61 protruding from the circumferential surface of the sleeve 6 , one end of the compression spring 31 abuts against the stamp seat 5 , and the other end of the compression spring 31 abuts against the limiting ring 61 .
[0041] The cleaning device of the present invention can increase the contact area between the compression spring 31 and the sleeve 6 and improve the structural strength of the device by setting a sleeve 6 between the threaded shaft 11 and the brush roller 2, and providing a limiting ring 61 protruding from the circumferential surface of the sleeve 6 at one end of the sleeve 6 close to the compression spring 31.
[0042] In some embodiments, the mounting shaft 1 and the brush roller 2 both extend in the vertical direction, the compression spring 31 is disposed above the brush roller 2, and the adjusting nut 41 is disposed below the brush roller 2. The adjusting nut 41 can provide support for the brush roller 2 to prevent the brush roller 2 from sliding off the mounting shaft 1.
