Automatic coil change device for coiled materials

Abstract

The invention relates to the technical field of battery manufacturing, in particular to an automatic coil change device for coiled materials. The automatic coil change device comprises a machine table, a left unreeling device, a right unreeling device and a rotating cutting device, wherein a left auxiliary roller, a right auxiliary roller and a plurality of fixed rollers are arranged on the machine table; the rotating cutting device comprises a bearing block, a bearing, a rotating body, a rotating mechanism, a rotary mechanism and a driving mechanism, wherein the bearing arranged on the bearing block, the rotating body is arranged on the bearing, the rotating mechanism is used for driving the rotating body to rotate on the bearing block, and the rotary mechanism is used for driving the bearing block to rotate; the rotating body comprises an upper part and a lower part; a gap for allowing materials to pass through is formed between the upper part and the lower part; and the rotating body is provided with a pressing mechanism used for compressing the material and a cutting mechanism used for cutting off the material. By arranging the rotating body, the rotating mechanism, the rotarymechanism, the driving mechanism, the pressing mechanism and the cutting mechanism, and automatic exchange of the material belts of the left unreeling device and the right unreeling device is realized.

Description

Technical field [0001] The invention relates to the technical field of battery production, in particular to an automatic roll exchange device for roll materials. Background technique [0002] Domestic lithium-manganese battery manufacturers have always implemented manual operation in the automatic winding machine for lithium-manganese batteries. Under the increasing market demand, the efficiency of manual winding of lithium-manganese batteries is about one minute, which greatly hinders With the development of enterprises, automation of winding has become an urgent need for enterprises. [0003] In the unwinding process of the material roll of the automatic winder, when the material of a roll is finished, the machine needs to be stopped for the continuity of the material, and then the remaining material of the roll is manually cut, and the remaining material The material is pasted on the new roll, the work efficiency is low. Summary of the invention [0004] The purpose of the pres...

Problems solved by technology

[0002] Domestic lithium-manganese battery manufacturers have always been manually operating the lithium-manganese battery automatic winding machine process. Under the ever-increasing market demand, the efficiency of winding lithium-manganese batteries by skilled hands is about one minute, which greatly hinders With the development of enterprises, the automation of winding has become an urgent need for enterprises

[0003] During the unwinding process of the material roll of the automatic winding machine, when the unwinding of a material roll is completed, for the continuity of the material, it is necessary to stop the machine, and then manually cut off the remaining material of the material roll, and remove the remaining material. The material is pasted on a new roll, and the work efficiency is low
