Problems solved by technology

[0002] The existing thermal gluing process of door panels and core panels mostly adopts the method of overall cold pressing or hot pressing gluing. The quality of door panel gluing is affected by the external environment. Changes in temperature and humidity will affect the instability of gluing quality. When cold pressing or hot pressing is glued together, the door will be deformed, seriously affecting the quality of the product, and the hot pressing cycle is long, the output is low, and the production cost is high

Abstract

The invention provides a hot-gluing processing process capable of preventing a door surface from deforming, which belongs to a door panel hot-gluing process. The hot-gluing processing process comprises the following process steps: coating assembly glue on the two surfaces of a core board; fitting the door panel to the core board; and sealing the door panel to be a to-be-glued door, firstly introducing the to-be-glued door into a plate feeding machine, then conveying the to-be-glued door to a glued plate hot press through a pressing conveying device, introducing the to-be-glued door to a gluedplate cold press through a pressing conveying device, and unloading the glued door plate through a plate unloading machine after passing through the pressing conveying device. The pressing conveying device comprises a bracket, a first pressing plate and a second pressing plate, wherein the second pressing plate can be arranged on the bracket in a lifting mode; and the first pressing plate and thesecond pressing plate can get close or away from each other. The hot-gluing processing process has the beneficial effects of preventing the door plate from deforming, guaranteeing stability of gluingquality, increasing the yield and reducing the production cost.
