Description

Technical Field

[0001] The utility model relates to the technical field of coating equipment, in particular to a coating roller anti-movement device for coating sheet materials. Background Art

[0002] In the sheet coating process, the stability of the coating roller directly affects the coating effect. Traditional coating roller devices often have axial displacement after long-term operation due to unreasonable structural design or improper material selection, which in turn affects the uniformity and thickness consistency of the coating layer. This not only reduces product quality, but also increases production costs and maintenance difficulty. In order to improve this phenomenon, a corresponding coating roller anti-displacement device is required.

[0003] Reference announcement number CN216447321U is a coating roll anti-movement device for producing BOPS sheets, which includes: a coating roller shaft, a bearing, a locking sleeve and a locking nut. The coating roller is sleeved on the outer ring of the bearing, and the inner ring of the bearing is sleeved on the coating roller shaft through the locking sleeve. The locking sleeve is annular, the outer ring of the locking sleeve is in contact with the inner ring of the bearing, and the inner ring of the locking sleeve is in contact with the coating roller shaft. The outer ring of the locking sleeve is a conical surface, and the inner ring of the locking sleeve is a cylindrical surface. A thread is provided on the outer ring of the locking sleeve. The locking nut is in contact with the side surface of the bearing and is tightened on the thread. This device can prevent the coating roller from moving axially and ensure the coating effect.
