Description
Technical Field
The application relates to the technical field of rubber die cutting, in particular to a die cutting method and a die cutting system for easy-to-draw rubber for a battery.
Background
The battery glue is generally composed of five layers of materials, namely PET release paper, first Mylar, easy-to-draw glue, second Mylar and base paper from top to bottom. Among them, the easy-open adhesive, also called stretch adhesive tape, reduces the adhesiveness of the adhesive tape by stretching so that it can be peeled off from an object. The easy-pulling glue is characterized by lightness and thinness, but still retains toughness.
When the battery glue is manufactured, the easy-to-draw glue is generally required to be arranged on the carrier film according to a preset jump distance to form an easy-to-draw tape roll, so that the subsequent automatic production is facilitated. For the wide jump distance of more than 10mm, the traditional full-pasting process is adopted and the partial distance is used as waste to be discharged, so that the utilization rate of the material is less than 50%, the cost of the easy-to-draw adhesive material is high, and the cost is not reduced easily.
In order to reduce the generation of excessive waste materials during production, the Chinese patent 201610325865.4 discloses an asynchronous die cutting method and a die cutting machine for realizing the method, and the method comprises the following steps of attaching a die cutting layer to an auxiliary material feeding layer; cutting the attached die-cutting layer, and sequentially cutting off the die-cutting layer; separating the cut die-cutting layer from the auxiliary feeding layer, and rolling the separated auxiliary feeding layer; feeding the base layer and the separated die-cutting layer for attaching, wherein the conveying speed of the base layer is higher than that of the auxiliary material feeding layer, and forming die-cutting raw materials of the die-cutting layer distributed on the base layer at equal intervals; the die cutting method and the die cutting equipment have the advantages that the die cutting raw materials distributed on the die cutting layer on the base layer at equal intervals are fed into the die cutting host machine for die cutting, the die cutting machine for achieving the method comprises the die cutting host machine, a rack, a discharging shaft, a fitting mechanism, a die cutting layer cutting mechanism, a die cutting layer and auxiliary feeding layer separating mechanism and a material collecting shaft, and the method and the equipment are efficient and rapid, and save materials.
The technical scheme avoids the generation of waste materials between two adjacent die-cutting products to a certain extent. However, since the easy-to-draw adhesive is light, thin and soft and has strong toughness, when the easy-to-draw adhesive tape roll is manufactured by the technical scheme, the easy-to-draw adhesive is easy to stretch and deform, difficult to peel and wrinkle or deform after being pasted, and a qualified easy-to-draw adhesive tape roll cannot be manufactured.
