Description

Automatic splicer cutter

Technical field:

The utility model relates to the technical field of automatic paper splicing machines, in particular to automatic paper splicing machine cutters.

Background technique:

In the process of paper material processing, it is often necessary to replace the roll material. For example, when the previous roll material is about to run out, the next roll material must be prepared. In order to make the replacement of the roll material not affect the normal paper material processing, You need to use an automatic paper splicer. The main working principle of the automatic paper splicer is to cut off the previous roll material that is about to run out on the feed side, and join the cut feed paper with the feed front end of the next roll material. For the automatic paper splicer, its cutter for cutting the paper is more important. The knife of the automatic paper splicer includes a fixed knife body and a moving knife body. The paper passes between the fixed knife body and the moving knife body, and the moving knife body moves to the side of the fixed knife body. The moving knife body and the fixed knife body form a shear Cutting action to cut the paper. In general automatic paper splicing machines, both the fixed knife body and the moving knife body use rectangular iron blocks, and the paper is cut off by using the friction between the moving knife body and the fixed knife body. However, this kind of knife structure has limitations, such as , sometimes the distance between the moving knife body and the fixed knife body is not adjusted well, it is easy to cause the paper material to be partially not cut or even not cut at all, and the existing knives are used when processing kraft paper and other thicker paper materials. , the processing effect is very unsatisfactory.

Utility model content:

The purpose of the utility model is to provide an automatic paper splicer cutter for the deficiencies of the prior art, which can quickly and effectively cut paper materials, and can also quickly cut thicker paper materials, with simple structure and better use effect.

In order to achieve the above object, the utility model adopts the following technical solutions:

It includes a fixed knife body and a moving knife body; the fixed knife body is long and has a plurality of serrations formed on the upper end; the moving knife body is long and has serrations on the lower end; Corresponding to the serrations of the movable cutter body, the gap between adjacent serrated teeth on the movable cutter body corresponds to the serrations of the fixed cutter body.

The beneficial effect of the utility model is that, through the cooperation of the saw teeth of the fixed knife body and the movable knife body, the paper material can be cut very quickly and effectively, and the thick paper material can also be cut quickly, and the use effect is obvious.

Description of drawings:

Fig. 1 is a structural representation of the utility model

Fig. 2 is the enlarged side view of the fixed knife body of the utility model

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described.

The following descriptions are only preferred embodiments of the present utility model, and therefore do not limit the protection scope of the present utility model.

See accompanying drawings 1 and 2, the utility model includes: a fixed cutter body 10, a movable cutter body 20; the movable cutter body 20 is provided with a mounting hole 23, through which the movable cutter body 20 can be installed on the splicing paper On the mobile device of the machine; the fixed cutter body 10 is elongated and has a plurality of sawtooth 11 formed on the upper end; the movable cutter body 20 is elongated and has a sawtooth 21 formed on the lower end; The gap 12 corresponds to the sawtooth 21 of the movable cutter body 20, and the gap 22 between the adjacent sawtooth 21 on the movable cutter body 20 corresponds to the sawtooth 11 of the fixed cutter body 10; When the movable knife body 20 moves to the fixed knife body 10, the sawtooth cooperation between the fixed knife body 10 and the movable knife body 20 can cut the paper material very quickly and effectively, and the use effect is obvious.

In order to increase the use effect, especially in order to quickly and effectively cut thicker paper materials, the following structure is specially adopted: in the width direction of the fixed knife body 10, the length of the top of the sawtooth 11 on the fixed knife body 10 is greater than the length of the bottom of the sawtooth 11; As can be clearly seen from Fig. 2, the sides of the sawtooth 11 of the fixed cutter body 10 are trapezoidal with a large upper part and a smaller lower part; The top of the top first pierces the paper material, and the moving knife body 20 continues to move to the fixed knife body 10, then the extrusion to the paper material can be completed, therefore, the thicker paper material can be cut off very conveniently.

In addition, both ends of the top of the sawtooth 11 of the fixed knife body 10 of the present utility model extend to the outer body of the fixed knife body 10. On the one hand, the sawtooth 11 can be used to pierce the paper; A moving knife body 20 is used to coordinate the coil feeding with different positions.

The utility model has the advantages of simple structure and better use effect.
