Kind Code:
A1
Abstract:
A process for applying a thin film to an inner wall of a barrel. The process comprises the following steps: a, feeding a barrel body (30), which has been manufactured in a previous procedure, to a stepping barrel-holding conveyor belt (10), and at this moment, a positional connection line of welded lugs on two sides being perpendicular to the conveying direction of the stepping barrel-holding conveyor belt (10); b, providing a first baking mechanism (20) at a start position area of the stepping barrel-holding conveyor belt (10), and heating and baking height areas of the welded lugs of the barrel body (30) by means of the first baking mechanism (20); c, conveying the barrel body (30) to a film-cutting and -application station (40) in a stepping manner, using a jacking-up mechanism (41) at the film-cutting and -application station (40) to jack up the barrel body, and at the film-cutting and -application station (40), applying cut-out profiling thin films to the areas of the welded lugs on an inner wall of the barrel body (30); d, conveying the barrel body (30) to a thin film pre-pressing station (50) in a stepping manner, and using a pre-pressing head (51) at the thin film pre-pressing station (50) to pre-press the thin films onto corresponding positions of the inner wall of the barrel body (30); e, a holding claw of the stepping barrel-holding conveyor belt (10) conveying the barrel body (30) to a continuous conveyor belt (60); and f, the barrel body (30), which has been subjected to press fitting, separating from the continuous conveyor belt (60) and entering the next procedure. By means of the process, thin films, which correspond to the positions of welded lugs, are applied to an inner wall of a barrel rapidly, conveniently and firmly.
