Description

Packaging film conveying mechanism Technical Field The utility model relates to the technical field of packaging film conveying, in particular to a packaging film conveying mechanism. Background The packaging film conveying mechanism is a mechanical device for conveying packaging films in the packaging process, and mainly aims to smoothly and continuously convey the packaging films from a reel or other supply sources to a packaging position so as to package products; The device has the following defects found in practical use: If the prior art protects the film transmission mechanism (CN 218931213U), when the device is started, the rear end of the film is stressed, and the front end drives the first moving rod and the second moving rod to move in opposite directions under the action of the tensile force, so that the film tensioning process is buffered, the situation that the film is suddenly pulled to cause the instant stress at the two ends of the film, and the film is instantaneously broken is effectively avoided, and the safety of the film is improved. As shown in the above document, the present film conveying device generally adopts a design of cooperation of a plurality of traction rollers and guide rollers, in which the traction rollers on both sides are generally firmly fixed on a mounting frame, resulting in that the distance between the traction rollers on both sides is kept constant, and the design of the fixed distance has a certain limitation in laying the packaging film, namely, it is difficult to regulate the conveying tension of the packaging film by flexibly regulating the distance between the traction rollers on both sides. Accordingly, the present application provides a packaging film transport mechanism to meet the need.
