Process and device for coating film on glass

Abstract

The invention discloses a process and device for coating a film on glass. Glass film coating processing process flow steps include an earlier stage glass treatment procedure, a glass sheet loading procedure, a glass cleaning procedure, a spraying section procedure, a film-coated glass drying section procedure, a film-coated glass cooling procedure and a glass sheet unloading procedure. The entire glass film coating processing device designed by the invention consists of a sheet loading section (A), a cleaning section (B), spraying section (C), a drying section (D), a cooling section (E) and a sheet unloading section (F), wherein the bottom end of a glass support frame (27) is provided with a plurality of drying wheels (10) which are driven to bear and move glass sheets by using a controlled servo motor (23); and a spraying device in the spraying section (C) mainly comprises the glass support frame (27), a front storage box (7), an upper sealing cover at the spraying position of a coating recovering groove (15), and the like. Due to the adoption of the process and the device, the glass film coating quality is ensured, and the problem that the treatment requirement of surface coating on glass with a low-viscosity coating is difficult to meet is solved.

Description

technical field [0001] The invention relates to the technical field of a film coating process and device, in particular, to a process and device for coating glass. Background technique [0002] Devices and processes for surface coating treatment of glass, such as curtain drench machine, paint drench machine and their coating process are suitable for glass, panel furniture, flat doors, cabinet side panels, solid wood composite floors, handicrafts, bamboo and wood curtains, etc. Primer or topcoat by flow coating. The curtain drenching machine and paint drenching machine are supplied with paint through the defoaming pump, and the pressure of the pump creates a drenching curtain between two drenching knives with adjustable spacing, and the workpiece is conveyed by a speed-adjustable horizontal conveyor perpendicular to the drenching curtain. Pass through the curtain at a constant speed to form a uniform coating on the surface of the workpiece. The film thickness after treatmen...
