Abstract

The utility model discloses a shearing machine slitter. The slitter is a flat circular knife, namely, a slitter body is a circular ring shape blade. Cutting edges are located on the outer ring of the slitter body, and the angle of the cutting edges is 30-40 degrees. Through the adoption of the shearing machine slitter with the structure, shape degree of the cutting edges of the slitter can be promoted; and the ensuring of service life of the slitter, reduction of replacement of the slitter, and frequency reduction of repairing and polishing are achieved, and the problem that in the prior art, burrs are easy to generate when pole pieces with a high density are grinded and sheared can be solved at the same time.

Description

A kind of cutter cutting knife

Technical field

The utility model relates to a kind of lithium ion battery production process equipment, especially a kind of cutter cutting knife.

Background technology

Lithium ion battery have voltage height, specific energy high, recycle often, the advantage such as memory time is long, not only on portable electric appts, be used widely such as mobile phone, DV and laptop computer, and be widely used in the big-and-middle-sized electrical equipment aspects such as electric automobile, electric bicycle and electric tool, therefore more and more higher to the safety requirements of lithium ion battery.

In the lithium ion battery production process, in cutting operation, need by cutter pole piece to be cut into suitable width.

Fig. 1 is the side view of cutter cutting knife in the prior art.As shown in Figure 1, cutter cutting knife of the prior art is generally flat dise knife, and namely its body 1 is circular blade, and blade 2 is positioned on the outer shroud of cutter body; And described cutter cutting knife is Knife with one blade.The angle A of knife edge part has significant impact to the cutting effect of cutting knife, and angle is excessive, then easily produces easily burr when rolling, shearing the high pole piece of density, and cutting knife is not sharp; Angle is less, and then cutting blade abrasion is very fast, need to cutting knife in use frequently change, reconditioning.

The utility model content

The purpose of this utility model is to overcome defective of the prior art, provides a kind of and is guaranteeing to avoid cutting knife, in the situation of wearing and tearing faster, makes blade comparatively sharp, thus avoid when rolling, shearing the high pole piece of density, producing burr the cutter cutting knife.

For addressing the above problem, a kind of cutter cutting knife of the present utility model, described cutting knife is flat dise knife, and namely its body is circular blade, and blade is positioned on the outer shroud of cutter body; The angle of described blade is 30～40 °.

The angle of described blade is 35 °.

Described cutter cutting knife is Knife with one blade.

The external diameter of described cutter body is 100mm, and internal diameter is 60mm.

Adopt the cutter cutting knife of the utility model structure, can promote the sharpness of cutting knife blade, in the service life that guarantees cutting knife, reduce that cutting knife is changed, when the frequency of reconditioning, can solve in the prior art problem that when rolling, shearing the high pole piece of density, produces easily burr.

The specific embodiment

In order to make those skilled in the art person understand better technical solutions of the utility model, the utility model is described in further detail below in conjunction with drawings and embodiments.

Shown in Fig. 2 to 4, a kind of cutter cutting knife of the present utility model, described cutting knife is flat dise knife, and namely its body 1 is circular blade, and blade 2 is positioned on the outer shroud of cutter body 1; The angle of described blade is 30～40 °, is preferably 35 °.

Described cutter cutting knife is Knife with one blade.

The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
