Description

SYNCHRONOUS LAMINATED-FILM CUTTING-OFF MACHINE

BACKGROUND

Technical Field

The present invention relates to a device for cutting off a laminated film on a gypsum board, and in particular to a synchronous laminated-film cutting-off machine.

Related Art

In the process of producing some boards such as gypsum boards, the boards need to be subjected to film lamination. When film lamination is performed on the boards, first continuous films need to adhere to the surfaces of the boards having been cut off, and then a cutting-off machine is adopted to cut off the continuous films. This process needs to be finished in the board conveying process, so as to execute a next process. At present, a method for synchronously cutting off a laminated film on a board comprises the steps of propelling the laminated film and the cutting-off machine by two independent power sources respectively, and adjusting the speeds of the two independent power sources through electrical devices to synchronize the laminated film and the cutting-off machine, so as to achieve the objective of making notches tidy. The method has the problems that 1 the two propulsion power sources are adopted for the board undergoing film lamination and the cutting-off machine and the speed regulation makes the synchronization subjected to precision limitation, so that the notches are not up to expectations, control complexity is also increased, and the stability of a device is reduced; and 2 the two power sources and corresponding electrical control devices also increase costs.
