Description

Technical Field

[0001] The utility model relates to the technical field of foil production machines, in particular to an automatic foil feeding device for pressing ear materials. Background Art

[0002] Copper foil is an indispensable material in the current lithium battery production, and acts as the negative electrode material in lithium batteries. In the production process of copper foil, the copper foil produced from the edge of the cathode roller is prone to burrs and is thick, which affects the quality of the copper foil product, so it is necessary to use a cutter to trim it. The cut ear material is reeled in separately by the reeling mechanism. During the reeling process, it is a common phenomenon that the ear material is torn and broken. When the edge is torn, the ear material may start to swing irregularly from the cutter. If it is not handled in time, it will seriously affect the production of copper foil. In serious cases, it will fall into the anode tank and even cause an accident.

[0003] For example, Chinese invention patent publication number CN114084714A discloses an automatic collection and reuse device for ear materials of a raw foil machine, comprising: a bottom box, sliding openings are opened on the left and right sides of the upper end surface of the bottom box, a first slider is slidably connected inside the sliding opening, a first double-axis motor is installed inside the bottom box, the upper end surface of the first slider is connected to a support plate, a mounting plate is connected to the middle of the upper end surface of the bottom box, a second double-axis motor is installed on the upper end surface of the mounting plate, first clamping covers are connected to the output ends of both sides of the second double-axis motor, second clamping covers are rotatably connected to the opposite sides of the left and right support plates, an ear material collecting roller is tightly connected between the first clamping cover and the second clamping cover, and the device is only used to collect ear materials and does not involve the problem of irregular swinging of torn edges of ear materials.
