Description

Film clamping mechanism of gypsum board winding film packaging machine Technical Field The invention relates to the technical field of gypsum board processing, in particular to a film clamping mechanism of a gypsum board winding film packaging machine. Background The plasterboard winding and packaging procedure is generally that a conveying chain plate drives a whole stack of plasterboards to slowly pass through a packaging station, a packaging machine drives a coiled winding film to circularly rotate and wind the plasterboards, and before winding, the free ends of the coiled winding film are generally clamped and fixed through a film clamping device so as to avoid the free ends to rotate along with the packaging machine. The conventional film clamping device is generally of a multi-clamping block serial structure, a gap is reserved between adjacent clamping blocks, an operator initially pulls the free end of a winding film on one side of a conveying chain plate, a packaging machine is controlled to drive the film to wind and move below the clamping blocks, a released film is attached to the bottom surfaces of the clamping blocks, the adjacent clamping blocks are controlled to be horizontally close, and the film is clamped and fixed between the gaps of the adjacent clamping blocks. If the winding film is not attached to the bottom surface of the clamping block in parallel and is in a single-side downward inclined state, when the clamping blocks are close to each other, the film on the inclined side cannot be clamped between the adjacent clamping blocks due to the fact that the film is far away from the working surface of the clamping block, and therefore the free end is easy to loosen and the clamping is not tight. Disclosure of Invention Therefore, the invention provides a film clamping mechanism of a gypsum board winding film packaging machine, which aims to solve the technical problem that a winding film in the prior art is not attached to the bottom surface of a clamping block in parallel, and one side far away from the clamping block cannot be clamped.
