A film roll inner folding device

Abstract

The invention provides a folding device for the inner side of a film roll. The folding device is simple in structure, suitable for folding the inner sides of tubular films of different sizes, improved in adaptability, simple in folding process, and high in folding efficiency. The folding device comprises a bracket. A film winding device corresponds to the bracket. The folding device is characterized in that supporting rods are respectively arranged on two sides of the bracket; a first cross rod and a second cross rod are respectively arranged on each supporting rod; the two ends of each first cross rod are connected through a first guide pillar respectively; the two ends of each second cross rod are connected through a second guide pillar respectively; first guide sleeves are respectively arranged at the two ends of each first guide pillar and each second guide pillar; the first guide sleeves are respectively connected with the first guide pillars and the second guide pillars in a sliding manner; the first guide sleeves are respectively connected with folding plates; the folding plates on the same side are movably hinged; the length of each second cross rod is greater than that of each first cross rod; the folding plates on the same side are triangular; and the widths of the upper ends of the folding plates are greater than those of the lower ends of the folding plates.

Description

technical field [0001] The invention relates to the technical field of film production equipment, in particular to an inner folding device for a film roll. Background technique [0002] In the film winding production process, it is necessary to fold the inner side of the tubular film. The existing folding method adopts manual folding, which is labor-intensive. The shape of the template is relatively fixed when folding. Folding needs to replace different folding templates, which makes the folding process complicated and the folding efficiency low. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a film roll inner folding device, which has a simple structure and is suitable for the inner folding of tubular films of different sizes, and improves the adaptability of the film roll inner folding device. The process is simple, so that the folding labor efficiency is high. [0004] In order to achieve the above object...
