A film transfer device for changing rolls

Abstract

The invention discloses a film roll changing conveying device, which belongs to the field of film conveying machinery and equipment. The film roll feeding mechanism, film unwinding mechanism and film bonding mechanism of the invention are fixedly arranged on the upper side of the film conveying base in sequence along the horizontal direction, and the two sides of the rolling plate above the unwinding fixed bracket are respectively provided with unwinding slots The rotation adjustment cylinder is installed obliquely upward between the rotation adjustment bracket and the film conveying base, the unwinding and feeding bracket is set on the upper side of the rotation adjustment bracket, and the film bonding mechanism includes a film bonding bracket, a film pressing mechanism, a gluing mechanism and a pulling mechanism. In the film crimping mechanism, a film bonding bearing plate is fixed horizontally between the film inlet guide roller and the film outlet guide roller of the film bonding support. The structure design of the invention is reasonable, the film can be changed automatically, and the ends of two rolls of film that are conveyed in sequence can be bonded quickly and efficiently, so that the film can be smoothly and continuously conveyed, the degree of automation of film conveying can be improved, and the needs of production and use can be met. .

Description

technical field [0001] The invention belongs to the field of film conveying machinery and equipment, and in particular relates to a film roll changing conveying 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 film, polypropylen...

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. During the transfer of the existing film roll, in order to ensure the continuity of the film transfer process, it is necessary to complete the unwinding process. The tail end of the conveyed film roll is bonded to the head end of the newly replaced film roll. The bonding between the existing two rolls of film is done manually. It is necessary to pull the end of the newly replaced film roll smoothly so that The ends of two rolls of film are superimposed and bonded. The existing film bonding is manually operated. The operation efficiency of film bonding is low, and it is difficult to achieve efficient and stable film bonding. The bonding process is complicated. It takes a long time for the side ends to be bonded, resulting in the need to stop the operation of the film roll replacement process, which reduces the efficiency of film production and processing, and the bonding of the ends of the film on both sides is manually operated, and the quality of film bonding is difficult to be guaranteed. , it is easy to produce skewed wrinkles during the bonding process of the film, it is difficult to achieve smooth and accurate bonding and continuous transmission of the film, and it cannot meet the needs of production, processing and use
