Description

Technical Field

[0001] The invention belongs to the technical field of electrode roll forming equipment, and in particular relates to a roll forming equipment with a cooling structure. Background Art

[0002] Dry electrode is an electrode preparation method used in lithium-ion battery production. Its main feature is that no solvent is used in the electrode preparation process, and the electrode material is prepared into sheets by drying and pressing. The dry electrode rolling equipment is mainly used to compound the dry powder electrode active material with the current collector to form an electrode membrane. A large amount of heat is generated during the rolling process. In order to ensure the molding and processing quality of the dry electrode, the equipment needs to be cooled.

[0003] For example, Chinese patent document (CN119502437A) discloses a dry-process electrode rolling device with controllable pressure roller gap, comprising a pressure roller having an inner cavity, at least two pressure rollers, and a roller gap between the two pressure rollers; a first touch member is arranged in the inner cavity and is separate from the pressure roller, the first touch member has a first touch portion, the first touch portion touches the inner wall of the inner cavity, the first touch portion and the roller gap are respectively located on the inner and outer sides of the roller wall of the pressure roller. Through the above technical solution, the problem of uneven distribution of dry powder material in the prior art is solved, which causes deformation of the pressure roller, reduces the gap between adjacent pressure rollers, affects the quality of the electrode diaphragm after forming, and may cause uneven thickness, uneven surface, etc. However, during use of the equipment, its mechanical energy will be converted into heat energy during rolling. If the heat accumulates, the temperature of the electrode diaphragm and the pressure roller will increase, and the thermal expansion of the material will cause the roller gap to change, which in turn affects the forming quality of the electrode diaphragm. Therefore, improvement is needed. Summary of the Invention

A feed port 4 is set on one side of the top of the pressure roller unit 3, and the feed port 4 is set on the side away from the center of the shell 1. The pressure roller unit 3 is provided with a winding unit 6 on both the upper and lower sides. The winding unit 6 is located at the center of the pressure roller drive unit 2, and one side of the winding unit 6 is fixedly connected to the inner wall of the shell 1;

[0055] The roller unit 3 is composed of multiple rollers, and a hollow shaft 5 is provided on both sides of the rollers.

[0056] Specifically, the device is placed in a suitable position, the water inlet 702 is connected to the external liquid supply device, and a finished product winding unit is set on one side of the shell 1 according to actual needs. When the feed port 4 conveys the material to the inside of the pressure roller unit 3, the pressure roller unit 3 will convey the electrode membrane after roller forming to the composite gap, and after passing through the composite gap, it is wound inside the winding unit 6. When it is necessary to perform single-sided bonding between the electrode and the membrane, the electrode roll is wound inside the winding unit 6 on the other side so that it can be rolled with the pressure roller unit 3 on one side. The electrode membrane is bonded at the composite gap, and then the bonded single-sided electrode is wound around the outer periphery of the winding unit 6 on the other side. When the electrode and the membrane need to be double-sided bonded, the electrode is wound inside the winding unit 6 on the other side so that it can be bonded to the electrode membrane after being rolled by the pressure roller units 3 on both sides at the composite gap at the same time.
