Problems solved by technology

The rewinding and unwinding spindle of the existing rewinding and unwinding device is usually driven by a chain drive. However, the speed of the chain drive is not uniform, and it is difficult to control the tension. When the chain drive is doing acceleration and deceleration, it is easy to produce Start and stop impact, at the same time, the structural design is complex, the transmission is two-stage transmission, assembly and maintenance are difficult, and the winding and unwinding accuracy is low

Abstract

The invention discloses a direct-connection cantilever-type self-reel-changing reeling and unreeling device. The direct-connection cantilever-type self-reel-changing reeling and unreeling device comprises a rotary disc; two unreeling spindles are symmetrically arranged on a first side surface of the rotary disc; servo motors which are connected to the two unreeling spindles are arranged on a second side surface of the rotary disc; a rotary spindle is coaxially connected to the center of the second side surface of the rotary disc; the other end of the rotary spindle is connected to a rotation driving mechanism; a bearing seat is additionally arranged between the rotary disc and the rotation driving mechanism; the rotary spindle is inserted into the bearing seat; two conical roller bearingsused for supporting the rotary disc are symmetrically arranged on the bearing seat; the two conical roller bearings are slidably resisted against the side surfaces of the rotary disc; and the direct-connection cantilever-type self-reel-changing reeling and unreeling device further comprises a material cutting component used for cutting off materials and a material pressing component. The by adopting the technical scheme of the invention, a transmission mode of a current reeling and unreeling device is improved; structural design is simplified; assembling and maintaining are facilitated; and the reeling and unreeling precision is enhanced.

Description

technical field [0001] The invention relates to the technical field of rewinding and unwinding of lithium battery pole pieces, in particular to a direct-connected cantilever type self-changing rewinding and unwinding device. Background technique [0002] During the production and processing of lithium batteries, it is necessary to discharge and cut off the entire plate of pole pieces. Therefore, it is necessary to use a winding and unwinding device to achieve this purpose. The rewinding and unwinding spindle of the existing rewinding and unwinding device is usually driven by a chain drive. However, the speed of the chain drive is not uniform, and it is difficult to control the tension. When the chain drive is doing acceleration and deceleration, it is easy to produce Start and stop impact, at the same time, the structural design is complex, the transmission is two-stage transmission, assembly and maintenance are difficult, and the winding and unwinding accuracy is low.
