Single-point supporting film rolling mill capable of displaying roller gap

Abstract

The invention discloses a single-point supporting film rolling mill capable of displaying a roller gap. The film rolling mill comprises a frame type bracket, an upper roller, an upper roller bearing, an upper roller bearing block, a lower roller, a lower roller bearing, a lower roller bearing block, an inverted prismatic table supporting seat, a roller gap change on-line sensing display, a slant wedge set, an oil cylinder, a driven gear pair, a driven gear, a main gear, a speed reduction motor, a base, an upper seat beam, a lower seat beam, a bolt, a bottom bolt, and the like. Compared with the prior art, the film rolling mill solves the problem of imbalance of supporting points at two ends, thus the problem of nonuniform thickness of a rolled lithium ion battery pole piece is solved; and the gap between two rollers can be displayed on line, and gap changes can be instantly corrected in a film rolling process so that the problem that the compactedness of the rolled roll lithium ion battery pole piece is nonuniform is solved.

Description

technical field [0001] The invention relates to a coating compaction and rolling equipment for positive and negative pole pieces of lithium ion batteries, in particular to a single-point support film rolling machine showing the gap between rolls. Background technique [0002] The existing lithium-ion battery positive and negative pole piece coating compaction rolling equipment is mainly composed of upper and lower rolls, frame, sliding bearing housing, reduction motor, transmission gear, the sliding bearing housing supports a roll, and the sliding bearing The two ends of the seat are respectively supported by the oil cylinder or the inclined pad. Adjusting the support of the oil cylinder or the inclined pad can change the gap between the roll supported by the sliding bearing seat and the other roll. The positive and negative pole pieces are coated by the gap between the two rolls. The layer is compacted by two rollers. The practice found that the main problem is that the oil...

Problems solved by technology

[0005] The task of the present invention is to overcome the problem that the motions of the sliding bearing housings supporting the oil cylinders at both ends of the lower roll are not synchronized, resulting in the inconsistency of the two ends of the roll gap, and to realize the visualization of the online change of the roll gap, so as to avoid the occurrence of uneven thickness in the rolling process. Unnecessary losses caused by timely detection, providing a
