[0002] A coating machine is a device used to evenly coat coatings on substrates such as paper and film. It is mainly used for producing various coated products. By adjusting the spacing between the rollers, the coating machine can improve the uniformity of winding and coating processing and can also meet different coating processing requirements.

[0003] Currently, there are still certain deficiencies in coating machines. For example, there is no working roller spacing adjustment device, and the spacing adjustment efficiency is low.

[0004] To overcome the low efficiency of roller spacing adjustment, a Chinese patent of the prior art (publication number: CN220072175U) discloses a coating machine with adjustable spacing of coating rollers. By setting the mutual cooperation among vertical plates, rotating motors, threaded rods, threaded blocks, bearing seats, adjusting rollers, sliding rods, and sliders, when it is necessary to adjust the spacing between the working roller and the adjusting roller, the rotating motor can be started through the control panel. The start of the rotating motor will drive the threaded rod to rotate, and the rotation of the threaded rod will drive the threaded block to move left and right. Furthermore, through the adjusting roller, the slider can slide on the surface of the sliding rod.

[0005] However, there are still certain deficiencies in the currently used coating machines. In the above document, the threaded rod drives one side of the adjusting roller. Although there is guidance, it is still prone to deviation, and there are jerks during operation, and the stability is insufficient. Secondly, the cloth on the coating machine may shift during operation, resulting in affecting the coating processing quality. Therefore, the existing structure needs to be improved.

The adjustment mechanism includes an external connection block 105, the external connection block 105 is symmetrically fixed on the side surface of the base 1, a movable frame 106 is slidably penetrated inside the external connection block 105, a connecting block 107 is fixed at the bottom of the movable frame 106, a first rotating block 108 is rotatably connected between the connecting block 107 and the guiding block 104, a rotating block 109 is fixed at the end of the movable frame 106, an extrusion roller 110 is rotatably connected inside the rotating block 109. When the coater winds the cloth, the rotating roller 2 is started through the control box 4 to wind the coating, and then the wound coating is guided by the connecting roller 3 to improve the processing effect. During the process, the output end of the motor can be started through the control box 4 to drive the threaded rod 103 to rotate. When the threaded rod 103 rotates, it can drive the guiding block 104 to perform threaded sliding. When the guiding block 104 performs threaded sliding, it can slide through the guiding groove 102.
