Technical Field
The application relates to the technical field of adhesive die cutting, in particular to a die cutting method and a die cutting system of easy-to-draw adhesive for a battery.
Background
The battery glue is typically composed of five layers of material, from top to bottom, PET release paper, first mailer, yi Lajiao, second mailer, and base paper. Among them, yi Lajiao, also called a stretch adhesive tape, is to reduce the tackiness of the adhesive tape by stretching so that it can be peeled from an object. The easy-to-pull adhesive is light and thin, but still retains toughness.
When the battery glue is manufactured, the easy-to-pull glue is generally required to be distributed on the carrier film according to a preset jump distance to form an easy-to-pull tape roll, so that the subsequent automatic production is facilitated. Aiming at a wide jump distance of more than 10mm, the traditional full-paste process is adopted to drain the part of the space as waste, so that the utilization rate of the material is less than 50%, and the cost of the easy-to-pull adhesive material is higher, thereby being unfavorable for reducing the cost.
In order to reduce excessive waste generated during production, chinese patent 201610325865.4 discloses an asynchronous die cutting method and a die cutting machine for realizing the method, wherein the method comprises the following steps of attaching a die cutting layer to an auxiliary feeding layer; cutting the bonded die-cut layers, and sequentially cutting off the die-cut layers; separating the cut die-cutting layer from the auxiliary feeding layer, and rolling the separated auxiliary feeding layer; the base layer is fed to be attached to the separated die-cutting layer, the conveying speed of the base layer is faster than that of the auxiliary material feeding layer, and die-cutting raw materials distributed on the base layer at equal intervals are formed on the die-cutting layer; the die cutting machine for realizing the method comprises a die cutting host machine, a frame, a discharging shaft, a laminating mechanism, a die cutting layer cutting mechanism, a die cutting layer and auxiliary feeding layer separating mechanism and a material collecting shaft.
The technical scheme avoids waste materials between two adjacent die-cut products to a certain extent.
