A film automatic roll changing film feeding device

Abstract

The invention discloses a film automatic roll-changing and film-feeding device, which belongs to the field of film conveying machinery and equipment. The film roll feeding mechanism, film unwinding mechanism and film pulling guide mechanism of the invention are fixedly arranged on the upper side of the film conveying base in sequence along the horizontal direction, the unwinding fixed bracket is fixedly arranged on the upper side of the unwinding translation guide plate, and the unwinding fixed bracket The upper side is horizontally rotatable and connected with a roll changing shaft. The unwinding and feeding bracket is set on the upper side of the rotating adjustment bracket. The output end of the film roll feeding cylinder is fixedly connected with the lower side of the unwinding and feeding bracket. The film pulling guide bracket is fixed vertically. On the upper side of the film conveying base on the side of the film unwinding mechanism, the horizontal film pulling mechanism and the pressing film guiding mechanism are fixedly arranged on the film pulling and conveying support in sequence from top to bottom. The invention has a reasonable structural design, can efficiently and smoothly realize automatic roll changing of the film, can pull and feed the end of the film stably and accurately, improves the automation degree of film transmission, and meets the needs of production and use.

Description

technical field [0001] The invention belongs to the field of film conveying machinery and equipment, and in particular relates to a film automatic roll-changing and film-feeding device, which is mainly used in the field of continuous conveying and processing of films. Background technique [0002] A film is a thin and soft transparent sheet, mainly made of plastic, adhesive, rubber or other materials. The scientific explanation of the film is: a two-dimensional material formed by depositing atoms, molecules or ions on the surface of the substrate. The film Material refers to a thin metal or organic layer with a thickness ranging from a single atom to a few millimeters. Thin films are widely used in electronics, machinery and printing industries, among which electronic semiconductor functional devices and optical coatings are the main applications of thin film technology. According to the classification of raw materials used, film materials can be divided into: polyethylene f...

AI Technical Summary

Problems solved by technology

During the production and processing of the existing film, as the film is unwound and conveyed, after all the film wound on the film roll placed at the unwinding station is unwound and conveyed, the new film roll needs to be rewound. Placed at the unwinding station for transmission, the existing entire film roll replacement process is manually operated, with a low degree of automation, and due to the large volume and heavy weight of the film roll, the labor intensity of the workers is relatively high. During the replacement process, it is also very easy to cause scratches and damages on the surface of the film roll, which affects the subsequent processing quality of the film roll. The end of the roll is pulled and sent, so that the head end of the newly replaced film roll can be pulled and conveyed smoothly and accurately until it overlaps with the tail end of the previous film roll that has been unwound and conveyed, so that the two rolls of film can be continuously conveyed after overlapping and bonding , the existing film end pulling and conveying is mainly carried out manually. It is extremely inconvenient for workers to pull and convey the film. The efficiency of film pulling and conveying is low, and in the process of manually pulling and conveying the film, It is difficult to achieve a stable and orderly pulling and conveying of the end of the film as a whole, and it is easy to cause local over-drawing of the film during the pulling and conveying process of the film, resulting in twisting and damage of the film, and manual pulling and conveying of the film is also easy to cause subsequent film damage. The overlapping and bonding process cannot be carried out smoothly and orderly, and it is difficult to realize the smooth and continuous high-tech transmission of the film, which cannot meet the needs of production, processing and use.
