When the vacuum chuck 2 drives the material to be cut to move transversely along the movable template 6, so that the material to be cut enters the groove of the second positioning protrusion 12 and abuts against the bottom of the groove, the pressure sensing part 13 measures the pressure generated by the abutment; when the set value is reached, the pressure sensing element 13 signals the drive motor 31 to stop.
The implementation principle of the positioning mechanism of the die cutting machine provided by the embodiment of the application is as follows:
the positions of the first and second positioning protrusions 11 and 12 are first adjusted by rotating the second screw rod 42.
The die cutting machine is started, and the movable template 6 swings towards the fixed template. Placing the material to be cut on the front surface of the movable template 6 from top to bottom in a state that the movable template 6 is inclined; the bottom edge of the material to be cut smoothly enters the groove of the first positioning protrusion 11 under the coordination of gravity and is completely attached to the bottom of the groove, so that the material to be cut is successfully positioned.
The vacuum chuck 2 is started to suck the material to be cut and drive the material to be cut to move along the transverse direction of the movable template 6, so that the side edge of the material to be cut smoothly enters the groove of the second positioning protrusion 12 and is completely attached to the bottom of the groove. Therefore, the material to be cut is accurately placed at the preset position, the problem of material positioning deviation caused by non-fitting or incomplete fitting of the material to be cut and the second positioning protrusion 12 during manual placement is solved, the material to be cut is enabled to obtain a more accurate positioning effect, and the material cutting quality is improved. The pressure sensing part 13 measures the pressure generated by the fitting; when the set value is reached, the pressure sensing piece 13 sends a signal, the driving motor 31 stops running, and the problem that the material to be cut is damaged because the vacuum chuck 2 continuously drives the material to be cut to move even though the side edge of the material to be cut is attached to the bottom of the groove of the second positioning protrusion 12 is solved.
The movable mould plate 6 continues to swing, the position of the material to be cut is fixed due to the adsorption of the vacuum chuck 2, and the situation that the material is displaced due to the swing of the movable mould plate 6 is reduced, so that the accuracy of material positioning during cutting can be improved, and the cutting quality is improved. In addition, the production of waste products can be reduced, so that not only are resources and cost saved, but also the pollution of waste materials to the environment is reduced.
After cutting, the movable template 6 is turned over again, and the vacuum chuck 2 stops adsorbing, so that the cut materials can be conveniently removed.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
