Abstract

The utility model discloses a copper foil slitting device, which belongs to the technical field of copper foil slitting. The technical scheme includes that the copper foil slitting device comprises a framework, a driving roll and a driven roll are disposed on the framework, an upper slitter and a lower slitter which correspond to each other are arranged on the framework and positioned between the driving roll and the driven roll, the upper slitter and the lower slitter are in linkage with the driving roll by a synchronous transmission mechanism, and the driving roll, the driven roll and the lower slitter match with each other so that an angle of a copper foil on the lower slitter ranges from 10 degrees to 15 degrees. The copper foil slitting device is reasonable in structure and good in slitting effect, and is used for slitting copper foils.

Description

The Copper Foil cutting device

Technical field

The utility model relates to a kind of cutting device, more particularly, relates in particular to a kind of Copper Foil cutting device.

Background technology

Cutting machine is very widely in sector applications such as Copper Foil, papermaking, plastic films.How cut out the product branch and satisfy customer requirement, high especially to requirement of products the Copper Foil industry customer especially, that want on the limit is neat, no burr, copper powder etc. can not be arranged.And existing cutting knife, the following shortcoming of ubiquity when cutting: the cornerite design of (1) Copper Foil and lower cutter is unreasonable, and is excessive like cornerite; Then cause the CONTACT WITH FRICTION arc length long; Copper Foil and lower cutter friction increase, and abrasion mark often appears in Copper Foil, cause the copper foil surface anti oxidation layer to destroy; Too small or do not have cornerite like cornerite, can't shear effectively between the then upper and lower cutting knife, quality problems such as the out-of-flatness of limit portion, zigzag, burr appear in the Copper Foil marginal portion; (2) knife edge angle design of upper and lower cutting knife is unreasonable, causes the excessive wear or the processing difficulties of the cutting knife knife edge; Cause cutting knife shortening in service life and increase production cost, also influence the effect of cutting Copper Foil simultaneously; (3) mesh degree of upper cutter and lower cutter is unreasonable, mainly is that the distance of engagement is excessive, causes the abrasion aggravation of cutting knife and the heating phenomenon occurs, influences the service life of cutting knife, has further increased production cost.

The utility model content

The purpose of the utility model is the deficiency to above-mentioned prior art, provide a kind of rational in infrastructure, cut effect preferably Copper Foil cut and use cutting device.

The technical scheme of the utility model is achieved in that a kind of Copper Foil cutting device; Comprise frame; On frame, be provided with drive roll and driven voller; On the frame between drive roll and the driven voller, be provided with corresponding upper cutter and lower cutter, upper cutter and lower cutter are through synchronous drive mechanism and drive roll interlock, and it is 10～15 ° that wherein said drive roll, driven voller and lower cutter cooperation make the angle of Copper Foil on lower cutter.

In the above-mentioned Copper Foil cutting device, the knife edge angle of described upper cutter and lower cutter is 5～8 °.

In the above-mentioned Copper Foil cutting device, described upper cutter is 0.3～1mm with the engagement distance of being sure to down.

After the utility model adopts said structure; Position through appropriate design drive roll, driven voller and lower cutter; The cornerite angle of Copper Foil on lower cutter is controlled in 10～15 ° of scopes; Make copper foil surface scratch can not occur, also edge out-of-flatness or problems such as zigzag, burr occur can not occur, guarantee the Copper Foil quality; Further; The knife edge angle of upper and lower cutting knife is arranged on 5～8 °, and the engagement distance of regulating upper and lower cutting knife simultaneously is 0.3～1mm, has reduced wearing and tearing and the heating phenomenon of cutting knife in cutting process widely; Prolong the service life of cutting knife, reduced production cost.

Description of drawings

Below in conjunction with the embodiment in the accompanying drawing the utility model is done further to specify, but do not constitute any restriction the utility model.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the structural representation of the utility model cutting knife knife edge;

Fig. 3 is the user mode sketch map of the utility model;

Fig. 4 is the local enlarged diagram at A place among Fig. 3.

Among the figure: frame 1, drive roll 2, driven voller 3, upper cutter 5, lower cutter 4, cornerite angle [alpha], knife edge angle beta, engagement distance L.

The specific embodiment

Consult Fig. 1 to shown in Figure 4; A kind of Copper Foil cutting device of the utility model; Comprise frame 1; On frame 1, be provided with drive roll 2 and driven voller 3, on the frame 1 between drive roll 2 and the driven voller 3, be provided with corresponding upper cutter 5 and lower cutter 4, the rotation of upper cutter 5 and lower cutter 4 is to be driven by drive roll 2 through synchronous belt and gear; It is 10～15 ° that drive roll 2, driven voller 3 and lower cutter 4 cooperations make the cornerite angle [alpha] of Copper Foil on lower cutter 4; This structure makes copper foil surface scratch can not occur, also edge out-of-flatness or problems such as zigzag, burr occur can not occur, guarantees the Copper Foil quality; The knife edge angle beta of upper cutter 5 and lower cutter 4 is 5～8 ° simultaneously; And upper cutter 5 is 0.3～1mm with following 4 engagement distance L earnestly; This structure has reduced wearing and tearing and the heating phenomenon of cutting knife in cutting process widely, has prolonged the service life of cutting knife.When the utility model used, Copper Foil up passed through lower cutter 4 backs to drive roll 2 places by driven voller 3 places under the traction of drive roll 2, through lower cutter 4 places the time, cooperate cutting of completion Copper Foil through upper cutter 5, lower cutter 4.
