Description

Technical Field

[0001] This utility model relates to the field of roller coating machine technology, specifically to an automatic deviation correction device for a roller coating machine. Background Technology

[0002] Adjustable coating rollers (or rubber roller connection structures) in roller coaters have weaker connection strength and stability than fixed rollers. Over long periods of rotation, they are prone to deflection due to wear and vibration. This deflection is difficult to detect visually, but it will cause abnormal roller operation. If not corrected, continued operation may accelerate component wear and trigger a chain reaction of problems in other parts of the equipment, affecting its overall service life.

[0003] The existing Chinese utility model patent with publication number CN210522949U discloses a roller coating machine, relating to the technical field of coating equipment. It solves the problem that while the lifting device of existing roller coating machines can correct vertical deviations of the roller to a certain extent, it cannot correct horizontal deviations. Horizontal deviations cause the roller to wobble during use, affecting the coating of steel plates. The invention includes a conveying device, a roller, a rotating rod, and a paint supply device. The paint supply device is positioned above the roller, which is horizontally positioned above the conveying device. The roller is sleeved and fixedly connected to the rotating rod, which has a limiting member to restrict its sliding. Adjustment devices are provided at both ends of the rotating rod. This utility model can correct deviations in the rotating rod and simultaneously prevent further deviations.

[0004] The aforementioned roller coating machine corrects the transmission rod by adjusting the devices at both ends of the transmission rod. The correction direction is vertical and horizontal, which cannot limit the axial displacement of the transmission rod. At the same time, without a monitoring structure, it cannot quickly match the displacement of the transmission rod during adjustment. The adjustment is done manually, which is prone to errors. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic deviation correction device for a roller coating machine, which solves the problems of the inability to correct axial deviation and the errors that easily occur during manual adjustment.

Limiting springs are inserted through the outer sides of the movable rods. A roller is movably mounted on one end of the movable rod. Laser ranging modules are fixedly mounted on both ends of the limiting frame.

[0008] Adjustment components, located at both ends of the coating roller, are used to adjust the position of the coating roller.

[0009] Preferably, the movable rod and the limiting frame are connected in a sliding manner. There are two movable rods in total. The movable rod is installed vertically on the left side of the limiting frame and horizontally below the limiting frame, and the movable rod points to the center of the coating roller cross-section.

[0010] Preferably, the roller and the movable rod are rotatably connected, the roller is in contact with the surface of the coating roller, and a disc-shaped limiting structure is installed at the top of the movable rod through a threaded structure. The laser ranging module points to the corresponding disc-shaped limiting structure at the top of the movable rod.
