It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.

As shown in fig. 1 and 2, an embodiment of the present utility model provides a label printing die-cutting mechanism, which comprises a base 1, a conveying device 2, a bracket 3, a cutter 4 and a blowing component 5.

The conveying device 2 is arranged on the upper surface of the base 1 and is used for conveying materials.

The support 3 is arranged on the base 1 and supports the cutter 4 and the blowing component 5.

The cutter 4 is slidably mounted in the bracket 3 and is located above the base 1, and the cutter 4 moves in the vertical direction to complete die cutting of materials.

In this embodiment, a specific air blowing component 5 is provided, so that when the cutter 4 cuts, the air blowing component 5 can be opened to blow the material, so as to provide a downward pressing power for the material, so that the material is separated from the cutter 4, and the subsequent die cutting effect is ensured.

Specifically, the blower assembly 5 includes a blower pipe 51, a blower plate 52, and a connector 53.

The air supply pipe 51 is arranged on the bracket 3; the blowing plate 52 is hinged inside the frame 3, is positioned at one side of the cutter 4, and has a through hole 521 in communication with the blast pipe 51.

The connecting piece 53 is disposed between the blower plate 52 and the cutter 4, and connects the cutter 4 and the blower plate 52 together, so as to control the movement of the blower plate 52 by driving the cutter 4, thereby making the blower pipe 51 blow or close.

Specifically, as shown in fig. 1, when the cutter 4 is pressed down, the blowing plate 52 is pulled to deflect to be communicated with the air supply pipe 51, so that air is sprayed onto the material, that is, the cutter 4 performs die cutting operation on the material at this time, and the blowing plate 52 blows air onto the material, so that the material cannot be bonded with the cutter 4, and the condition of poor die cutting effect caused by change of the material position can be avoided.

In addition, compare in publication number CN214323597U has proposed a self-adhesive label printing cross cutting device, and this application need not to realize the spacing to the material with the help of compression roller and material contact, realizes the spacing to the material through non-contact's mode promptly, can further prevent to lead to the poor condition of cross cutting effect to take place because of material and part bonding, reaches the purpose that promotes the cross cutting effect.

When the cutter 4 is reset, as shown in fig. 3, the blowing plate 52 is attached to the cutter 4 and seals the air supply pipe 51, i.e. the air is not sprayed out any more, so as to ensure that the material can move along with the conveyor 2.
