Continuous asynchronous transfer-paste film cutting technology

Abstract

The invention relates to a continuous asynchronous transfer-paste film cutting technology, thus improving cutting product material utilization rate, and realizing seamless connection; the film cutting technology comprises raw material cutting, splicing and shaping cutting a splicing overlapping portion; the raw material cutting step comprises an asynchronous cutting device including a cutting roller set and an absorption roller set; the cutting roller set comprises a knife mold and a knife mold bottom roller in a lower position; the knife mold is connected with a first servo motor; the absorption roller set comprises a hollow roller and is driven by a second servo motor; absorption holes are uniformly arranged on a periphery of the hollow roller; a plug-hole sector pad is arranged in the hollow roller and connected with a negative pressure inhalation device; one side of the absorption roller set is provided with a triangle separating piece; the second servo motor has bigger speed than that of the first servo motor, and a speed proportion is adjustable. The continuous asynchronous transfer-paste film cutting technology saves cost and knife resources, and is applied to electronic product outer film cutting technology.

Description

technical field [0001] The invention relates to a die-cutting process, more specifically, relates to a die-cutting process for continuous and asynchronous transfer of membrane products. Background technique [0002] At present, precision equipment is required to die-cut thin products such as mobile phone protective film, computer protective film, electronic printing products, double-sided stickers, and aviation equipment. At present, there are various die-cutting products on the market, and the demand of the industry is very large. However, although some existing die-cutting machines are equipped with multiple stations, each station performs the same processing action, that is, the The processed strips are die-cut with one knife. This die-cutting machine is suitable for processing a single product. For some products that require large product size and not very strict precision requirements, they are still die-cut as a whole set at present, which brings certain advanta...
