Fixed-length drawing composite technology and equipment

Abstract

The invention discloses a fixed-length drawing composite technology and equipment. The fixed-length drawing composite technology can achieve fixed-length drawing of a laser film before composition and laser paper after stripping, so that control of laser graphic plate length on the laser film before the composition and laser graphic plate length on the laser paper after the stripping. A laser film fixed-length drawing system and a laser paper fixed-length drawing system are further arranged on a rack of the fixed-length drawing composite equipment; the laser film fixed-length drawing system carries out the fixed-length drawing on the laser film before the composition by controlling the conveying speed of the laser film before the composition to achieve the same laser graphic plate length after the composition; the laser paper fixed-length drawing system carries out the fixed-length drawing on the laser paper formed after the stripping by controlling the conveying speed of the laser paper formed after the stripping. Therefore, the fixed-length drawing composite technology and the equipment can produce the laser paper in the same laser graphic plate length, and smooth subsequent processing of the laser paper is ensured.

Description

technical field [0001] The invention relates to a composite process and its equipment, more specifically, the invention relates to a fixed-length stretching composite process and its equipment. Background technique [0002] The existing composite equipment generally includes a frame and a film unloading device, a paper unloading device, a gluing device, a composite device, a drying device, a stripping device, a laser film recovery device, and a finished product winding device respectively arranged on the frame; The above-mentioned film releasing device, gluing device, composite device, drying device, stripping device and laser film recovery device are arranged in sequence along the conveying direction of the laser film, and the above-mentioned paper releasing device, compound device, drying device, stripping device and finished product collection The roll device is arranged sequentially along the conveying direction of the paper tape, and the above-mentioned composite device...

AI Technical Summary

Problems solved by technology

[0004]Although the existing composite equipment can transfer the laser graphics on the laser film to the paper tape to make laser paper products, due to the existing laser Due to the limitation of the film production process, the laser film itself will have a laser graphic version length error during the production process; at the same time, in the process of producing laser paper products with composite equipment, after the laser film is stretched, heated and dried, the laser film The length of the laser graphic version will fluctuate, so that the error of the laser graphic version of the laser film will be further expanded; after the paper tape is stretched, heated and dried, the length of the paper tape will also change, and the laser film It is different from the change in the length of the paper tape during the stretching, heating and drying process, resulting in inconsistent lengths of the laser graphics and texts composited on the paper tape. Therefore, the length of the laser graphics and texts transferred to the paper tape will be even more inconsistent. , which will bring great difficulties to the subsequent processing of laser paper products (such as die-cutting, printing, etc.), and sometimes even cause the subsequent processing of laser paper products to fail to proceed smoothly
