Optionally, not shown, the strip pattern interrupted rolling mill further comprises a pressure feedback system, the pressure feedback system being connected to the controller. The pressure feedback system is used for acquiring the rolling pressure between the pattern roller 60 and the supporting roller 20, so that the controller can adaptively adjust the deflection angle of the first driving motor according to the rolling pressure, and further the automation degree of the strip pattern intermittent rolling equipment and the precision of different pattern rolling depths are improved.

In this alternative, in the first embodiment of the pressure feedback system, the pressure feedback system includes a strain gauge disposed in the pattern roller 60 or the back-up roller 20, and a converter for converting the resistance change of the strain gauge into a corresponding strain value, the converter is connected to the controller, and the controller correspondingly controls the first driving motor according to the received strain value, so that the first driving motor correspondingly controls the deflection angle of the abutting cam 30, thereby adjusting the rolling pressure, and the pressure adjustment precision is high, and the pattern rolling quality is good.

In this alternative, the pressure feedback system of the second embodiment includes a pressure sensor connected to the first roller shaft of the back-up roller 20, and the pressure sensor is connected to the controller for acquiring the rolling pressure applied by the pattern roller 60 after abutting against the second roller shaft of the pattern roller 60; when the patterned roller 60 is pressed down, the second roller shaft top of the patterned roller is abutted against the pressure sensor, the pressure sensor acquires the rolling pressure applied by the patterned roller 60 and transmits the rolling pressure value to the controller, the controller correspondingly controls the first driving motor according to the received rolling pressure value, and then the first driving motor correspondingly controls the deflection angle of the abutting cam 30, so that the rolling pressure is adjusted, the pressure adjusting precision is high, and the patterned rolling quality is good.

The strip pattern discontinuous rolling installation of the invention works for example as follows:

example 1: controlling a servo motor connected with the supporting roller 20 through an operation screen and a PLC (programmable logic controller), so that the linear speed (namely the pattern rolling advancing speed of the strip) of the supporting roller 20 is 0.05m/s, at the moment, the propping cam 30 is propped against and contacts with the roller 70 for pattern rolling, the servo motor propping the cam 30 is started to rotate reversely after 10s, the loosening is completed within 3s through the rotation speed control and is kept to be loosened for 5s, and then the servo motor propping the cam 30 rotates forwards and completes the propping and locking within 2 s; after 10s, the servomotor against the cam 30 starts the reverse rotation and completes the aforesaid action in the same time, after which the action is repeated regularly, with the rolling strip obtained being: regular strips with the length of the ginning section of 0.05x10 equal to 0.5m, the length of the non-ginning section of 0.05x (3+5+2) equal to 0.5m, and the distance between the ginning section and the non-ginning section equal.

Example 2: the supporting roller 20 is connected with a servo motor through an operation screen and a PLC (programmable logic controller), so that the linear speed (namely the pattern rolling advancing speed of the strip) of the supporting roller 20 is 0.05m/s, the supporting cam 30 is abutted against the roller 70 for pattern rolling at the moment, the servo motor abutting against the cam 30 is started to rotate reversely after 20s, the loosening is completed within 3s through the rotation speed control, the loosening is kept for 3s, the servo motor abutting against the cam 30 rotates forwards, and the supporting roller 20 is abutted against and locked within 2 s; after 20s, the servomotor against the cam 30 starts the reverse rotation and completes the aforesaid action in the same time, after which the action is repeated regularly, with the rolling strip obtained being: regular strip material with the length of an embossed section of 0.05x20 equal to 1m, the length of an unembossed section of 0.05x (3+3+2) equal to 0.4m and unequal spacing between the embossed section and the unembossed section.
