Description

A traction trimming device for biaxial stretching heat shrinkable film processing

technical field

The utility model relates to the technical field of film edge trimming equipment, in particular to a traction edge trimming device for biaxial stretching heat shrinkable film processing.

Background technique

After the film is processed, the edge materials on both sides need to be cut and trimmed to make the edges of the material smooth and reach the required size specifications. During the film shearing process, trimming devices are usually installed on both sides of the film, and the cutting blade is in contact with the film. When the film moves forward with the rotation of the roller, the stationary cutter moves relative to the film to cut the film. Trimming work.

The traction edge trimming device in the prior art usually has unstable traction force and no tension cutoff, which easily causes the film to slide left and right, causing the film edge material to be rewound on the production roller, affecting production, and there is a certain amount of shaking when the cutter trims the film. The flatness cannot be guaranteed when cutting the edge, which reduces the quality of the film after slitting. Usually, a fixed knife holder is used, and the slitting can only be aimed at one size of film. In some cases where the film slitting size is required to be narrow, the distribution of slitting knives If it is more compact, the vibration generated during the cutting process of the film will increase, which will cause uneven cutting edges.
