Polymer battery pole piece ball milling device

Abstract

The invention relates to the technical field of polymer batteries, and discloses a polymer battery pole piece ball-milling device which comprises a transmission shaft, a rotating disc is fixedly connected to the top end of the transmission shaft, a collecting ring is fixedly connected to the outer side of the bottom end of the rotating disc, and a movable groove I is formed in the center of the top of the rotating disc; one end of the movable groove I is fixedly connected with strong springs which are evenly distributed, and the other end of each strong spring is fixedly connected with a movable plate. Through the designed moving plate and the fixed plate, when the amount of materials added into the ball milling tank is larger, the overall weight of the ball milling tank pushes the moving plate to move, so that the ball milling tank is gradually inclined relative to the center line, the materials are obliquely spread, the space at the top of the ball milling tank is utilized, more materials can be put into the ball milling tank at a time, and the service life of the ball milling tank is prolonged. And the condition that the impact force and the extrusion force of a single grinding body on the materials are shared by more materials during high-speed rotation of the ball-milling tank is avoided.

Description

technical field [0001] The invention relates to the technical field of polymer batteries, in particular to a ball milling device for pole pieces of polymer batteries. Background technique [0002] In the preparation of polymer batteries, the manufacture of pole pieces requires five processes: slurry preparation, slurry coating, pole piece rolling, pole piece cutting, and pole piece drying. For the preparation of slurry, it is necessary to use The planetary high-energy ball mill crushes and mixes the materials. The planetary high-energy ball mill is equipped with several ball mill tanks that revolve with the turntable and perform high-speed self-propagation on the circumference of the rotating disc. The balls in the ball mill tank are under the action of inertial force. The material forms a large high-frequency impact and friction for rapid and fine grinding. [0003] Due to the vertical placement of the ball mill tank in the existing planetary high-energy ball mill, the mat...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing battery pole piece ball milling device proposed in the background technology, the present invention provides a polymer battery pole piece ball milling device, which has the functions of eccentric rotation of the ball milling tank, automatic tilting of the ball milling tank, and automatic rotation of the ball milling tank. The advantages of reciprocating tilting motion and constantly changing shaking degree of the ball mill solve the problems in the above-mentioned background technology that the backlog of materials in the ball mill causes the impact force of the grinding body to be shared, the utilization rate of the inner space of the ball mill is low, and the crushing efficiency of the ball mill is low.
