Abstract
The utility model discloses a dead knife of a rewinding machine, which is used in papermaking industry, and has the characteristic of reduced use cost. The dead knife comprises a knife body and a knife edge which are in a split structure, wherein the knife edge is connected onto the knife body. In the utility model, as the knife body and the knife edge which are in the split structure are adopted, i.e., the knife body and the knife edge are respectively manufactured, in such a way, after the dead knife is used for a long time, and is damaged, only the knife edge is replaced, while the knife body can be continuously used, and further, the use cost is greatly reduced. The dead knife disclosed by the utility model is particularly suitable to be popularized and applied in the papermaking industry.
Description
Technical field
The utility model relates to a kind of cutter, is specifically related to the rewinding machine bed plate that uses in a kind of paper industry.
Background technology
At present, the rewinding machine bed plate is used for papermaking more, paper and relevant industries. in paper industry, cut the blade on the cutting machines such as various craft papeies, white board, newsprint, cigarette paper, characteristic such as require to have the precision height, sharp, durable.
The rewinding machine bed plate mainly adopt material such as 9CrSi, GCr15, T10, but it is durable relatively poor early mainly based on integral structure.Along with the cemented carbide industry develop rapidly, the bed plate of part with the whole hard alloy material appearred, because therefore its too high making tooling cost and material cost is not used widely in industry; Its major cause is that whole cutter is also just scrapped, and has increased use cost greatly after blade damages.
The utility model content
Technical problem to be solved in the utility model provides a kind of rewinding machine bed plate that reduces use cost.
The technical scheme that its technical matters that solves the utility model adopts is: the rewinding machine bed plate, comprise the cutter hub and the blade of branch body structure, and described blade is connected on the cutter hub.
Further be that described blade adopts Hardmetal materials to make.
Further be that described cutter hub adopts the 2Cr13 material.
Further be that described blade is connected on the cutter hub by adhesive layer.
The beneficial effects of the utility model are: owing to adopted cutter hub and the blade that divides body structure, be that cutter hub and blade are made respectively, like this, when after long-term use, causing blade to damage, only changing blade gets final product, and cutter hub still can continue to use, thereby greatly reduces use cost, is particluarly suitable for applying on the rewinding machine bed plate of paper industry.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the local enlarged diagram at A place among Fig. 1.
Be labeled as among the figure: cutter hub 1, blade 2, adhesive layer 3.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Shown in Figure 2 as Fig. 1, rewinding machine bed plate of the present utility model comprises the cutter hub 1 and blade 2 of branch body structure, and described blade 2 is connected on the cutter hub 1.Because adopted the cutter hub 1 and blade 2 that divide body structure, promptly cutter hub 1 is made respectively with blade 2, like this, when after long-term use, causing blade 2 to damage, only change blade 2 and get final product, and cutter hub 1 still can continue to use, thereby greatly reduce use cost.
In the above embodiment, cutter hub 1 and blade 2 can be linked together by screw, or directly link together by interference fit.As preferred mode, as shown in Figure 2, described blade 2 is connected on the cutter hub 1 by adhesive layer 3, and this mode can finely prevent that in use blade 2 breaks away from cutter hub 1; Certainly, on the basis of this mode,, then more can guarantee the connection reliability between cutter hub 1 and the blade 2 if again blade 2 is interference fitted on the cutter hub 1.
Claims (4)
