Abstract

The invention discloses a pole piece roller compression machine which comprises an unrolling mechanism, a delivery mechanism, a roller compression mechanism and a rolling mechanism. The roller compression mechanism comprises an upper compression roller and a lower compression roller which are oppositely arranged and a compression roller driving mechanism used for driving the upper compression roller and the lower compression roller to move relatively to conduct roller compression. The roller compression mechanism further comprises an inverse driving mechanism coupled to the upper compression roller and / or the lower compression roller. The inverse driving mechanism controllably applies action force with direction opposite to the compression roller drawing close direction on the upper compression roller and / or the lower compression roller to remove or weaken compression roller shock. The pole piece roller compression machine enables the two compression rollers to maintain stable in interval change, and avoids undesirable change in compression of pole pieces by rollers, so that the machine can improve roller compression quality and prolong service life of devices.

Description

Technical field

[0001] The invention relates to a battery pole piece production equipment, in particular to a roller press for rolling a coated pole piece. Background technique

[0002] The preparation of lithium battery pole pieces is generally to first coat a mixture of active materials and various additives on the substrate. The coated substrate is rolled to form pole pieces. The roll forming process of the pole pieces affects the thickness of the pole pieces. Uniformity and thickness, etc., in turn affect the performance of the battery, so higher requirements on the roller press. The industry's research on this technology has never stopped.

[0003] Chinese patent document 200810054790.6 discloses a hydraulic servo battery pole piece rolling mill, which adopts a hydraulic cylinder for pressing down on the bearing housing where the pressure roller is installed, and the bending hydraulic pressure for adjusting the gap between the two rollers is installed outside the bearing hous...
