in the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Fig. 1 is a schematic diagram of a mask perforating device in the embodiment of the invention.

The invention provides a mask punching device (see figure 1), which controls the up-and-down reciprocating motion of an upper knife through a pneumatic control system, positions mask cups through the front side surface of a positioning block and two side surfaces of a boss on the positioning block, and further realizes the accurate punching of the breathing valves of the mask cups.

The cutting device comprises a rack 1, a cylinder 2, a connecting seat 3, an upper cutter 4, a fixed support 5, a guide shaft 6, a positioning block 7 and a lower cutter 8; install cylinder 2 on the frame 1, 2 head erection joint seats 3 of cylinder, install sword 4 on the connecting seat 3, and fixing support 5 installs in frame 1, and guiding axle 6 installs on fixing support 5, and locating piece 7 installs in frame 1, and lower sword 8 installs on locating piece 7.

In one embodiment of the present invention, the positioning device specifically comprises a positioning block 7 connected to the frame 1. The front side of the positioning block 7 and two side surfaces of the lug boss on the positioning block position the mask cup 9, and the accurate positioning of the mask cup 9 is ensured.

In one embodiment of the invention, a guide shaft 6 is mounted on the fixed support 5, which guide shaft functions specifically to guide the upper knife and also to eject the cut film.

The invention also provides 1 set of pneumatic control system, which is used for saving manpower for opening the breather valve of the mask cup 9.

The working process of the invention is as follows:

firstly, the opening of the breather valve of the mask cup 9 is placed on the lower knife 8, the pedal switch is stepped on, the piston rod of the cylinder 2 is ejected out, so that the upper knife 4 moves downwards to punch, then the piston rod of the cylinder 2 is retracted, and the cutting film is ejected out by the guide shaft. Thus, the process of opening the breather valve of the mask cup 9 is completed.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed.
