The following explains the working principle of the follow-up roll cleaning device provided by the embodiment of the invention:
when the cleaning device is used, the adjusting mechanism 1 drives the cleaning roller 5 to be close to or far away from the working roller, and the pressing force of the cleaning roller 5 and the working roller can be accurately controlled. The cleaning roller 5 is driven by the play mechanism 2 to move along the axial direction of the working roller, the axial play of the cleaning roller 5 is completed, and the roller cleaning area is adjusted. When the cleaning roller 5 is replaced, the moving parts of the adjusting mechanism 1, the shifting mechanism 2 and the quick-change mechanism 3 move out along with the cleaning roller 5, and after the replacement is finished, the moving parts of the adjusting mechanism 1, the shifting mechanism 2 and the quick-change mechanism 3 move integrally until the moving parts are inserted into the fixed part.

The following provides a detailed description of the components of the follow-up roll cleaning device and the working principle thereof:
in the embodiment of the present invention, as shown in fig. 3 and fig. 4, the adjusting mechanism 1 is used to drive the cleaning roller 5 to move close to or away from the working roller, so as to achieve precise control of the pressing force, and as an example, the adjusting mechanism 1 includes: a fixed seat 101, a bearing seat assembly 102, a cylinder seat 103, an adjusting cylinder 104, a damping piece 105 and a connecting rod 106; the cylinder base 103 is fixed on the fixed base 101, the adjusting cylinder 104 is fixed on the cylinder base 103, and a piston rod of the adjusting cylinder 104 is hinged to the connecting rod 106 at a first hinge point; one end of the damping piece 105 is fixed on the cylinder base 103, and the other end is hinged with the connecting rod 106 at a second hinge point for tensioning the connecting rod 106; the two ends of the cleaning roller 5 are limited in the bearing seat assembly 102, the bearing seat assembly 102 and the cleaning roller 5 are hinged to the third hinged point, and the first hinged point is located between the second hinged point and the third hinged point.
In this arrangement, the damping element 105 is hinged to the connecting rod 106 at a second hinge point, which can be regarded approximately as a fixed point. The adjusting cylinder 104 acts to push the connecting rod 106 to rotate around the second hinge point, and the bearing seat assembly 102 rotates along with the connecting rod 106, so that the distance between the bearing seat assembly 102 and the working roll is changed. The two ends of the cleaning roller 5 are limited in the bearing seat assembly 102 and move along with the bearing seat assembly 102, so that the distance between the cleaning roller 5 and the working roller is adjustable, and the pressing force is adjusted. Further, by using the damper 105 as one end of the fixed link 106, the damping of the damper 105 is controlled at: during normal roll cleaning operation, the damping member 105 can generate enough pulling force to maintain a preset pressing force between the cleaning roll 5 and the working roll. When the resistance between the cleaning roller 5 and the working roller exceeds the normal range, the damping piece 105 plays a role in buffering to enable the cleaning roller 5 and the working roller to be relatively far away, and damage to the cleaning roller 5 and the working roller is avoided.
It can be understood by those skilled in the art that the bearing seat assembly 102 may be an assembly formed by assembling one or more parts, and the bearing seat assembly 102 is used for the summary in the implementation of the present invention, and the specific structure thereof is not limited.
In the embodiment of the present invention, by providing the damping member 105, a buffering effect can be provided to protect the work roller and the cleaning roller 5 from being damaged easily when an unexpected situation such as jamming occurs, for example, as shown in fig. 5, the damping member 105 includes: a cylinder 1051, a disc spring 1052, a nut cover 1053 and a pull rod 1054; one end of the cylinder 1051 is open, the disc spring 1052 is located in the cylinder 1051, one end of the nut cover 1053 passes through the opening of the cylinder 1051 to be connected with the disc spring 1052, the other end of the nut cover 1053 is connected with the pull rod 1054, and the pull rod 1054 is hinged with the connecting rod 106 at the second hinge point. So set up, elastic force through dish spring 1052 plays damping cushioning effect.
Further, the end of the nut cover 1053 within the cylinder 1051 is larger in size than the opening of the cylinder 1051, limiting the pull-out stroke of the damping member 105. With this arrangement, when the piston rod of the adjusting rod is extended, the nut cover 1053 is restricted by the cylinder 1051 and does not move downward, so that a sufficient pressing force can be maintained between the cleaning roller 5 and the work roller. In the process of cleaning the roller after the adjustment is finished, the position of a piston rod of the adjusting cylinder 104 is not moved as a fulcrum, the elastic force of the disc spring 1052 and the reaction force of the pressing force are respectively applied to a second hinge point and a third hinge point on the connecting rod 106, and when the cleaning roller 5 meets the resistance with the working roller, the disc spring 1052 is compressed to enable the cleaning roller 5 to bounce for a short time to skip over a resistance meeting area, so that the surface of the working roller and the surface of the cleaning roller 5 are prevented from being damaged due to overlarge pressure.
