Embodiment

[0038] A horizontal lithium battery pole piece slitting machine is used for cutting battery pole pieces during the lithium battery production process. The specific structure and working principle of the slitter will be described in detail below.

[0039] Such as Figure 1 to Figure 4 As shown, the slitting machine includes a frame 1, a cutting device 2, an alcohol wiping device 3 and a negative pressure dust removal device. The frame 1 includes a bottom plate 14, a base, a pressing plate, a top plate and side plates. Wherein, the bottom plate 14 is arranged at the bottom of the slitting machine, and is a rectangular structure. The base is a "concave" structure with grooves, and has two, the bottom width of which is consistent with the bottom width of the bottom plate 14, which are respectively arranged at the front and rear ends of the bottom plate 14. closed above. The side plates are arranged on both sides of the bottom plate 14 in the width direction, and respectively co...

Abstract

The invention discloses a horizontal lithium battery pole piece splitting machine, and belongs to the field of lithium battery manufacturing. The horizontal lithium battery pole piece splitting machine comprises a machine frame, wherein a cutting device is arranged in the machine frame, and comprises a pair of rotating shafts arranged in the horizontal direction; the rotating shafts are sleeved with annular blades; a feeding port is formed in the position, above a gap between the pair of rotating shafts, of the machine frame; and a discharging port is formed in the position, below the gap, of the machine frame. According to the horizontal lithium battery pole piece splitting machine provided by the invention, the distance between the rotating shafts can be conveniently adjusted, so that the probability that burrs and wavy edges appear on a slit lithium battery pole piece is reduced.

Description

technical field [0001] The invention belongs to the technical field of lithium battery manufacturing, and more specifically relates to a lithium battery pole piece cutting machine. Background technique [0002] Lithium batteries have the characteristics of high energy, environmental protection, long service life, and easy to carry. With the increasing demand for lithium batteries and more and more styles for different application fields, the production capacity of lithium batteries is also gradually increasing to meet various forms of demand. The production and manufacture of lithium battery pole pieces is a key process in the production process of lithium batteries, including slurry preparation, pole piece coating and drying, pole piece roll compaction and pole piece die-cutting. [0003] Among them, the die-cutting of the pole piece is to use a die-cutting machine to die-cut the large-sized pole piece strip into multiple smaller-sized pole piece strips according to the va...
