The guide component 54 can have multiple, and four guide components 54 are shown in the figure to stably guide the pushing component 53.

[0043] In some embodiments, the driving component 52 can drive the pushing component 53 to move in the horizontal direction, and the pushing component 53 can drive the coating die assembly 3 to move in the horizontal direction. Specifically, the coating die assembly 3 can be slidingly connected with the rack 1 in the horizontal direction through a slide rail, the guide column 541 is arranged in the horizontal direction, and the piezoelectric ceramic 521 can deform in the horizontal direction.

The first inclined surface and the second inclined surface are both inclined surfaces, and the relative sliding of the two can drive the coating die assembly 3 to move. When a large range adjustment of the coating die assembly 3 is required, the driving member 532 is used to drive the sliding block 533 to move the coating die assembly 3, for example, when the distance to be moved by the coating die assembly 3 is greater than the stroke range of the piezoelectric ceramic 521 or greater than a preset range, the controller controls the driving member 532 to act.

The mounting base 41 is fixedly mounted on the frame 1, and the detection mechanism 4 is located above one end of the coating roller 2. The detector 43 can be a laser sensor, which obtains the radial runout of the coating roller 2 by non-contact detection of the outer circumferential surface of the coating roller 2.

The adjustment platform 44 can be manually adjusted using a knob to adjust the positions of the support member 42 and the detector 43, for example, their horizontal and vertical positions, so that the detection position of the detector 43 is within the optimal range.

[0053] In summary, the embodiment of the present application provides an adjusting device for a coating machine. The jump of the coating roller 2 is monitored in real time by the detection mechanism 4. The detection data is fed back to the controller. The controller gives an instruction output to the piezoelectric ceramic 521 according to the detection data. The piezoelectric ceramic 521 drives the pushing component 53 to move. At this time, the guide component 54 guides the movement of the pushing component 53, so that the movement direction of the pushing component 53 is a straight line coaxial with the piezoelectric ceramic 521. Thus, the pushing component 53 drives the coating die assembly 3 to move. The change of the position of the coating die assembly 3 can compensate the influence of the jump of the coating roller 2 on the coating distance. The compensation effect can be monitored and fed back by the detection mechanism 4, so as to realize closed-loop control. Thus, the influence of the jump of the main roller of the existing coating machine on the stability of the equipment is completely solved. The performance bottleneck of the coating machine is broken, and the efficient and stable operation of the coating machine is ensured. Based on the above compensation mode of the jump of the coating roller 2, the coating machine can use a coating roller 2 with lower installation and processing precision, and the jump of the coating roller 2 is allowed to be larger. Since the closed-loop control is realized, the influence of the jump of the coating roller 2 can be eliminated, so that the installation and processing precision requirements of the coating roller 2 can be reduced, thereby reducing the equipment cost, facilitating equipment maintenance, and ensuring equipment production.
