Problems solved by technology
The gap between the coating head and the back roller has a great influence on the coating effect. Most of the existing coating machines use the straight top method of the screw or the wedge-shaped block driven by the screw to adjust the gap between the die head and the back roller, which has poor precision and Due to the large friction coefficient, it is difficult to adjust the gap online

The invention discloses a precise fine adjustment mechanism for optical film coating, and belongs to the field of parts of optical film coating machines. According to the technical scheme, the precisefine adjustment mechanism is characterized by comprising a mounting plate, side plates, a top plate, a bottom plate, a front supporting plate and a rear supporting plate, the side plates, the top plate, the bottom plate, the front supporting plate and the rear supporting plate form a box structure, and the box structure is mounted on the mounting plate; and a screw rod is rotatably connected in the box body structure, a nut is in threaded connection to the screw rod, a lower wedge-shaped block is fixed on the nut through a screw, an upper wedge-shaped block is movably arranged on the box bodystructure, and the lower inclined face of the upper wedge-shaped block is in contact with the upper inclined face of the lower wedge-shaped block. The precise fine adjustment mechanism has the advantage that the die head clearance can be adjusted online with high precision.
Description
technical field [0001] The invention relates to the field of optical film coating machine components, in particular to a precision fine-tuning mechanism for optical film coating. Background technique [0002] The application of optical film began in the 1930s. In modern times, optical films have been widely used in the fields of optics and optoelectronics technology to manufacture various optical instruments. The coating machine is mainly used for the surface coating process production of film, paper, etc. This machine is to coat the rolled substrate with a layer of glue, paint or ink with specific functions, and then wind it up after drying. It adopts a special multi-functional coating head, which can realize various forms of surface coating production. The winding and unwinding of the coating machine is equipped with a full-speed automatic film splicing mechanism, and the PLC program tension closed-loop automatic control. The gap between the coating head and the back rol...
