Problems solved by technology
Most of the hot rolling devices in the prior art heat the roll indirectly through oil heating. This heating method not only takes a long time to heat the roll, but also has a short heating time and distance for the pole piece. , and due to the large heat dissipation of the pole piece itself, it is not enough to effectively improve the performance of the pole piece

Embodiment 1
[0034] Example 1 A hot rolling device for lithium battery pole pieces
[0035] Such as figure 1 As shown, a lithium battery pole piece hot rolling device is respectively provided at the feed inlet and the discharge port of the roller press, and the lithium battery pole piece hot rolling device can be arranged under the steel roller 10 on the roller press, or placed Above the lower steel roller 11 of the roller press. The hot rolling devices for lithium battery pole pieces in this embodiment are all placed under the steel roller 10 on the rolling machine. Two hot rolling devices for lithium battery pole pieces are arranged symmetrically on the front and rear sides of the lower steel roller 11 of the roller press respectively along the line connecting the center of the steel roller of the roller press. In this embodiment, the front side of the steel roller of the roller press is the feed mouth, and the rear side is the outlet.

The invention discloses lithium battery pole piece hot rolling devices. The lithium battery pole piece hot rolling devices are arranged on a feeding port and a discharging port of a rolling machine respectively, the lithium battery pole piece hot rolling devices comprise hot steel roller sets adopting electrical heating and pulling and leading mechanisms which are used for pulling pole pieces to enable the pole pieces to be wrapped in hot steel rollers while in a S shape, the pulling and leading mechanism on one side of the feeding port of the rolling machine pulls the pole pieces on the hot steel rollers to the feeding port of the rolling machine, the pulling and leading mechanism on one side of the discharging port of the rolling machine pulls the pole pieces to the hot steel rollers, and the pulling and leading modes of the pulling and leading mechanisms are any one of A an individual pulling and leading mode and B a combined pulling and leading mode. By means of the devices, the contact areas of the pole pieces and the hot steel rollers during heating can be increased, and the pole piece performance can be improved; the devices are suitable for a lithium battery pole piece processing plant and are used in a rolling technology in lithium battery pole piece production.
Description
technical field [0001] The invention belongs to the technical field of lithium battery production and manufacturing, and relates to a lithium battery pole piece processing device, in particular to a lithium battery pole piece hot rolling device. Background technique [0002] With the popularization of lithium battery applications in society, users have put forward higher requirements on the performance of battery pole pieces, such as lithium battery energy density, capacity, and service life. The manufacturing process of lithium battery pole pieces includes mixing, coating, rolling, slitting and tabs. The purpose of rolling is to make the combination of lithium battery active material and foil more firm and dense. Uniform thickness. The currently used cold rolling press, because at room temperature, the temperature of the roll and the pole piece is at natural temperature, the hole frame structure of the active material on the lithium battery pole piece is easily broken duri...
