Embodiment Construction

[0023] In order to make the technical solutions and advantages of the present invention clearer, the exemplary embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all implementations. Exhaustive list of examples. And in the case of no conflict, the embodiments and the features in the embodiments of the present invention can be combined with each other.

[0024] The inventor noticed in the course of the invention that the existing roller presses are generally equipped with bulky frames with complex structures, large equipment weights, large footprints, and long stress loops. In addition, the mechanism for adjusting the roll gap contains a large number of parts, the operation is cumbersome, and the accuracy is low. As a result, during rolling, the pole pieces are not well stressed and the rolling precision ...

Abstract

The invention provides a short stress line type pole piece rolling press. The short stress line type pole piece rolling press comprises an upper roller mechanism, a lower roller mechanism, an upper bearing seat, a lower bearing seat and a roller gap adjustment mechanism; the upper roller mechanism is connected with the upper bearing seat; the lower roller mechanism is connected with the lower bearing seat; the upper bearing seat is connected with the lower bearing seat through a guide shaft; the roller gap adjustment mechanism is connected with the upper roller mechanism and is used for adjusting a roller gap between the upper roller mechanism and the lower roller mechanism. The short stress line type pole piece rolling press is simpler and more reliable in structure; a stress loop line is shorter when a pole piece is rolled and pressed; the rolling and pressing precision and the rolling and pressing quality can be improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery pole piece manufacturing equipment, in particular to a pole piece rolling machine, in particular to a short stress line type pole piece rolling machine. Background technique [0002] In the manufacturing process of lithium batteries, the slurry is coated on copper foil, aluminum foil and other current collectors, and after drying, it needs to be compacted with a roller press to make the joint between the active material and the current collector more solid and dense, and the thickness is uniform. , thereby increasing the energy density of the battery. [0003] In the prior art, a roller press is often used. The main working principle of the roller press is to compact the electrode material of the lithium battery pole piece through the relative movement of the upper and lower roller bodies to generate pressure. At present, the existing pole piece rolling machine, such as a lithium battery...
