Metallized film breadth linearly adjustable type splitting machine and unit thereof

Abstract

The invention discloses a metallized film breadth linearly adjustable type splitting machine. the metallized film breadth linearly adjustable type splitting machine comprises a feeding mechanism, a splitting mechanism and a film rolling mechanism which are arranged sequentially from front to back according to the technological process. The splitting mechanism comprises a splitting cutter assembly and a movable locating mechanism. a film is conveyed between the splitting cutter assembly and the movable locating mechanism. a film pressing mechanism is arranged between the feeding mechanism and the splitting mechanism, and a film pressing mechanism is arranged between the splitting mechanism and the film rolling mechanism. each film pressing mechanism comprises a rocker. The upper end of the rocker is hinged to a rack. The lower end of the rocker extends to the upper portion of an adjusting plate and can make contact with the film. the metallized film breadth linearly adjustable type splitting machine has the advantages that operation is convenient, relative sliding between a cutter head and a shaft is prevented effectively, adjustment of the film splitting breadth is flexible and various, and the rotation angle of a splitting cutter is precise.

Description

technical field [0001] The invention relates to the technical field of metallized films, in particular to a linearly adjustable metallized film width slitting machine and its unit. Background technique [0002] The metallized film width adjustable linear slitting machine is a device that cuts the metallized film processed by the vacuum coating machine according to the width requirement. It includes a feeding mechanism, a cutting mechanism, and a film rolling mechanism. The feeding mechanism is used to feed the metallized film to be cut, the slitting mechanism is used to cut the fed metallized film, and the film rolling mechanism is used to The slit metallized film is wound. [0003] At present, the existing metallized film width linear adjustable slitting machine has the following disadvantages: [0004] (1) The knife head positioning device in the slitting mechanism is mostly like the structure of the knife head positioning device disclosed in the film slitting machine di...

AI Technical Summary

Problems solved by technology

[0004] (1) The knife head positioning device in the slitting mechanism is mostly like the structure of the knife head positioning device disclosed in the film slitting machine disclosed in the patent application 201420418295.X, specifically a film roll with cutting grooves. The knife head of this structure The positioning device makes the film width after slitting only a multiple of the width of the cutting groove, and the slitting of other width films cannot be realized; in addition, the film roll is a cylindrical structure, and the film passes between the film roll and the knife head. The stability of transmission and cutting is poor

[0005] (2) The existing slitting knife is in a fixed state during slitting. In actual slitting, due to mechanical vibration and other factors, the knife head will be offset, resulting in a decrease in cutting accuracy

When tightening, the structure fully uses the friction between the bolt and the shaft to fix the position of the cutter head, and there is a risk of loosening

[0006] (3) During the transmission process of the film, if the tension is uneven, phenomena such as floating and wrinkling will occur. In actual work, it has been found that the above phenomena cannot be prevented well only by setting the tension roller

However, after the speed of the motor-driven winding device reaches a certain value, continuing to increase the speed of the winding device will affect the unwinding effect of the feeding device, resulting in problems such as film slipping and twisting
