Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Examples: as shown in fig. 1-3, a film positioning mechanism for a film laminating machine comprises two supporting pieces 20, wherein a connecting rod 21 is arranged between the two supporting pieces 20, at least two sliding blocks 22 which are in sliding connection with the connecting rod 21 are arranged on the connecting rod 21, positioning devices 23 are arranged at the front ends of the outer sides of the two sliding blocks 22, the positioning devices 23 are rotatably connected to the side walls of the sliding blocks 22, and a channel 24 for conveying films is formed between the positioning devices 23 and the sliding blocks 22; the positioning device is matched with the compressor for use, so that the processed products are accurately positioned, and the distance between the sliding blocks can be adjusted for positioning when the processed products with different specifications are processed; the positioning stability of the processed product is improved, the film pasting standard is ensured, the qualification rate of the processed product is improved, and the production cost is saved.
