It can be seen that the prior art still needs to be improved and enhanced.

Utility model content

In view of the shortcomings of the prior art above, the purpose of this utility model is to provide a slitting mechanism, aiming at solving the technical problem of the complex structure of the slitting mechanism of the printing machine in the prior art.

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

A cutting mechanism, comprising a bottom plate and two side plates, the two side plates are horizontally connected with a first auxiliary roller, a working table and a second auxiliary roller; the first auxiliary roller, the working table and the second auxiliary roller The top of the top is flush; each side plate is provided with a mounting plate, and each mounting plate is respectively provided with a cylinder; above the workbench is provided with a cutter mounting frame, which is located above the workbench. The two ends of the knife mounting frame are respectively connected with the piston rod of the corresponding cylinder; several cutting knives are detachably arranged on the cutting knife mounting frame.

In the slitting mechanism, each cutter includes a knife handle and a blade arranged at the bottom of the knife handle respectively.

In the described cutting mechanism, the cutter mounting frame is provided with a first straight hole vertically along its length direction, and the cutter mounting frame is provided with a second straight hole horizontally along its length direction; each cutter is respectively passing through the first straight hole; the handle of each cutter is provided with a horizontal through hole, and a bolt is respectively inserted in the first straight hole corresponding to each cutter and passed through the corresponding horizontal through hole.

In the slitting mechanism, the cutter installation frame is provided with scale lines along its length direction.

In the slitting mechanism, a groove is formed vertically on the top of each side wall, and the two ends of the cutter mounting bracket are respectively inserted into the corresponding groove sink.

Beneficial effects: the utility model provides a slitting mechanism. Compared with the prior art, the slitting machine provided by the utility model has a simple structure. The actual production requires that the printed matter be cut into several strips. The cylinder drives the cutter mounting frame to move up and down, which is easy to operate and easy to maintain and repair later. Further, by setting the first straight groove and the second straight groove on the cutter installation frame, it is convenient to adjust the position of the cutter and meet the cutting requirements of different printed matter.

Detailed ways

The utility model provides a cutting mechanism. In order to make the purpose, technical solution and effect of the utility model clearer and clearer, the utility model will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Referring to Fig. 1 to Fig. 3, the utility model provides a cutting mechanism.

A kind of slitting mechanism, comprises bottom plate 11 and two side plates 12, and first auxiliary roller 21, workbench 20 and second auxiliary roller 22 are connected horizontally on two pieces of side plates (the workbench and workbench and the second auxiliary roller 22 cannot be seen from the viewing angle of Fig. 1 The second auxiliary roller), the tops of the first auxiliary roller, the workbench and the second auxiliary roller are flush; each side plate is respectively provided with a mounting plate 3, and each mounting plate is respectively provided with a cylinder 4; the workbench A cutter mount 5 is arranged above the top of the cutter mount, and the cutter mount is located above the workbench, and the two ends of the cutter mount 5 are respectively connected with the piston rod 41 of the corresponding cylinder; the cutter mount is detachably provided with Several cutting knives6.

Preferably, each cutting knife includes a handle 61 and a blade 62 arranged at the bottom of the handle, and a blade 600 is arranged at the bottom of the blade, and the blade is arranged obliquely upward. Typically, the blade and handle are connected by screws. When the blade is worn out, it can be easily replaced with a new one.

Preferably, the cutter mounting frame is provided with a first straight hole vertically along its length direction (not observed in the figure), and the cutter mounting frame 5 is provided with a second straight hole 502 horizontally along its length direction; Pass the cutting knife through the first straight hole respectively; the knife handle of each cutting knife is respectively provided with a horizontal through hole (observed in the figure), and a bolt 71 is respectively inserted in the first straight hole corresponding to each cutting knife and through the corresponding horizontal vias. In actual use, each cutter can be adjusted to a proper position, and then the nut 72 corresponding to the bolt is locked to fix the cutter.

Preferably, the cutter installation frame is provided with scale lines along its length direction, and an indicator line 611 can also be provided on the top of the knife handle, which is aligned with the edge of the bottom, so as to facilitate accurate adjustment of the position of the cutter and improve Slitting accuracy.

Further, a groove is vertically provided on the top of each side wall (not observed in the figure), and the two ends of the cutter mounting bracket are respectively inserted into the corresponding groove sink (as shown by the dotted line in Figure 2). ). The grooves on the side wall play a position-limiting effect on the two ends of the cutter mounting frame to avoid shaking when the cutter mounting frame moves up and down.

As shown in FIG. 3 , in actual operation, the printed matter 90 (such as composite paper) passes around the first auxiliary roller 21 , the working table 20 and the second auxiliary roller 22 after printing. The cylinder pushes the cutter mounting frame to move down, the blades 600 of the cutter are against the upper surface of the workbench 20, and the printed matter 90 is in contact with each blade 600 to realize slitting. In actual use, the number of cutters can be pre-determined for different printed materials and the position of each cutter can be adjusted to adjust the actual cutting position. By setting the first auxiliary roller and the second auxiliary roller, it is convenient for the printed matter to reach and leave the working table smoothly. It should be noted that in actual work, the printed matter is realized by the transmission and pulling mechanism (or winding mechanism, etc.) of the printing machine, and the paper pulling mechanism (or winding mechanism, etc.) itself is not within the scope of protection of the present utility model.

From the above analysis, it can be seen that the slitting machine provided by the utility model has a simple structure, and the printed matter can be slit into several strips according to actual production requirements by detachably arranging a plurality of cutters on the cutter mounting frame. The cylinder drives the cutter mounting frame to move up and down, which is easy to operate and easy to maintain and repair later.

It can be understood that those skilled in the art can make equivalent substitutions or changes according to the technical solution of the utility model and the utility model concept thereof, and all these changes or substitutions should belong to the protection scope of the utility model.
