Problems solved by technology

In the acid pouring process, the electrode plate passes through the acid pouring roller, which provides pre-pressure through the compression spring, and squeezes the lead paste on the electrode plate passing through the acid pouring roller, so as to control the density and polarity of the lead paste. The thickness of the plate; however, the consistency of the lead paste density, plate thickness, and plate weight of the plate produced by the current coating process is not good, resulting in poor consistency of the performance parameters of the single battery, which affects the use of the battery pack life

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0026] Such as figure 1 , figure 2 As shown, a device for accurately controlling the pickling pressure roller includes a frame, a pressure adjusting device 4, a balanced pressure roller support device, a plate conveyor belt 1, a pickling pressure roller 2 located above the plate conveyor belt, and Support roller 3 under the plate conveyor belt. The supporting roller is rotatably arranged on the frame. The support roller is located directly below the acid-leaching roller. The pickling roller includes a roller shaft 2.1 and a roller 2.2 rotating on the roller shaft. The roller is set horizontally. The shaft of the support roller is set horizontally. The roller shaft is parallel to the rotating shaft of the support roller. The pickling roller is in contact with the upper surface of the plate conveyor belt, and the support roller is in contact wit...

Abstract

The invention discloses a device for accurately controlling an pickling roller, and aims at providing the device for accurately controlling the pickling roller, which can effectively control consistency of pole plate lead plaster density, pole plate thickness and pole plate weight, and improve consistency of single accumulator parameters. The device comprises a rack, a pressure adjustment device, a balanced roller support device, a pole plate conveyor belt, a pickling roller positioned above the pole plate conveyor belt, and a support roller positioned under the pole plate conveyor belt. The pickling roller comprises a roll shaft and a roller rotationally arranged on the roll shaft. The balanced roller support device comprises two support mechanisms. Each support mechanism comprises a vertical support cylinder arranged on the rack, a support piston arranged in the vertical support cylinder in a sliding manner and a vertical support rod arranged on the lower end face of the support piston. The lower end of the vertical support rod of one support mechanism is connected with one end of the roll shaft, while the lower end of the vertical support rod of the other support mechanism is connected with the other end of the roll shaft.

Description

Technical field [0001] The invention relates to the field of paste coating of battery plates, and in particular to a device for accurately controlling acid-sprinkling pressure rollers. Background technique [0002] In the field of power batteries, in order to meet the needs of power and cruising range, multiple batteries are usually connected in series to form a battery pack. In the power battery pack, the consistency of the performance parameters of each single battery determines the service life of the entire battery, and the consistency of the plate parameters is the most important factor affecting the consistency of the single battery. [0003] The current coating process usually involves coating the wet plate with paste, and then performing acid showering. During the acid showering process, the electrode plate passes through the acid shower roller, and the acid shower roller provides pre-pressure through a compression spring to squeeze the lead paste on the electrode plate pa...
