Novel film applicator

Abstract

The invention relates to a novel film coating machine, comprising a machine frame, a work-table, two guide rails, two hanging plates, a lead screw and an electric motor. The work-table is fixed on the machine frame; the guide rails are respectively arranged on both sides of the work-table, and the hanging plates are arranged at both ends of the work-table; the two hanging plates are connected with the two ends of by a bearing; a bearing housing is coated on the bearing, and the right end of the lead screw is connected with a belt wheel; the electric motor is fixed on the lower part of the right hanging plate, the belt wheel on the electric motor is connected with the belt wheel arranged at the right end of the lead screw, and the lead screw is coated in the nut; the film costing device comprises a riser, a slider, a fixing guide rail, an optical axis, a rubber shaft, frame strips, a connect plate, a nut, a linear bearing and an electric motor. The invention has the advantages of that the picture is fixed, the method that the rubber shaft moves horizontally and rolls for film coating in the inverse direction is adopted; the stability of film costing is enhanced and the film coatingquality is improved; the gap between the rubber shaft, the movement speed of the rubber shaft and the rolling speed is adjustable; the film coating quality is ensured and the thickness of the film coat is controlled.

Description

technical field [0001] The invention relates to a novel coating machine. Background technique [0002] Existing film coating equipment mainly includes rubber shafts, worktables, etc. During processing, the picture is fixed flat on the workbench, and the movement of the worktable drives the picture to pass through the rubber shaft on the upper part of the film coating equipment, so that The paint is covered on the surface of the picture to complete the film coating; during the film coating process, the glue shaft rolls synchronously with the movement of the picture, and the paint on the glue shaft is continuously replenished. However, there are serious defects in this common film coating method. Since the rubber shaft is passively rolled along with the movement of the picture during film coating, the uniformity of the film coating and the firmness of the adhesion are relatively poor, which affects the overall coating of the picture. Film quality; and this coating method can ...
