[0002] In the thermal transfer process of digital printing machines, the transferred film needs to be cut off, and then a new transfer film is used to transfer the next batch of products. The existing transfer film cutting mechanism must use a cutting knife, but because the transfer film will be tightened during the transfer process, the transfer film may be cracked when cut by a cutting knife, resulting in uneven cuts. When transferring again, the uneven part needs to be cut off first, which not only wastes the transfer film, but also affects the transfer efficiency. Utility Model Content

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A film cutting mechanism of a digital printing machine comprises two lifting mechanisms arranged opposite to each other, and the two lifting mechanisms are respectively used to be arranged on both sides of a frame of the digital printing machine, a heating wire fixing seat is provided on the lifting mechanism, and a heating wire is connected between the two heating wire fixing seats; the heating wire fixing seat is also provided with a tensioning mechanism for tensioning the heating wire.

[0006] Preferably, the lifting mechanism is a lifting cylinder, a cylinder barrel of the lifting cylinder is connected to the frame, and a telescopic rod of the lifting cylinder is connected to the heating wire fixing seat.

[0007] Preferably, the heating wire fixing seat comprises a connecting rod and a fixing rod connected vertically, the other end of the connecting rod is connected to the lifting mechanism, the heating wire is connected to the other end of the fixing rod, and the tensioning mechanism is arranged on the fixing rod.

[0008] Preferably, the fixing rod is provided with a mounting hole, and the heating wire is passed through the mounting hole.

[0009] Preferably, a connecting seat is provided at one end of the fixing rod connected to the connecting rod, and the heating wire is fixed through the connecting seat after passing through the two mounting holes.

[0010] Preferably, the tensioning mechanism is a tensioning spring, one end of the tensioning spring is connected to the fixing rod, and the other end of the tensioning spring is connected to the heating wire.

[0011] Preferably, the connecting rod includes a first connecting part and a second connecting part, the width of the first connecting part is greater than the width of the second connecting part, the thickness of the first connecting part is less than the thickness of the second connecting part, the lifting mechanism is connected to the lower surface of the first connecting part, and the other end of the second connecting part is connected to the fixing rod and has the same thickness as the fixing rod.

[0012] Compared with the prior art, the film cutting mechanism of a digital printing machine in the embodiment of the utility model has the following beneficial effects: a lifting mechanism is arranged on both sides of the frame, a heating wire fixing seat is arranged on the lifting mechanism, a heating wire is connected between the two heating wire fixing seats, and a tensioning mechanism for tensioning the heating wire is also arranged on the heating wire fixing seat. After installation, the horizontal tension state of the heating wire is ensured under the action of the tensioning mechanism.

Since the heating wire is melted and cut, the transfer film will not be torn during the film cutting process, thereby ensuring the neatness of the incision, thereby avoiding the waste caused by cutting uneven transfer film and ensuring the transfer efficiency.

After installation, the horizontal tension state of the heating wire 6 is ensured under the action of the tensioning mechanism. When die cutting is required, the heating wire 6 is first heated, and then the heating wire 6 is moved up by the lifting mechanism to cut the transfer film. Since the heating wire is melted and cut, the transfer film will not be torn during the film cutting process, thereby ensuring the neatness of the incision, thereby avoiding the waste caused by cutting uneven transfer film and ensuring the transfer efficiency.

[0021] In this embodiment, the lifting mechanism is preferably a lifting cylinder 1, the cylinder barrel of the lifting cylinder 1 is connected to the frame, and the telescopic rod of the lifting cylinder 1 is connected to the heating wire fixing seat 2. The heating wire fixing seat 2 includes a connecting rod 3 and a fixing rod 4 connected vertically, the other end of the connecting rod 3 is connected to the lifting mechanism, the heating wire 6 is connected to the other end of the fixing rod 4, and the tensioning mechanism is arranged on the fixing rod 4.

[0022] Specifically, the fixing rod 4 is provided with a mounting hole 41, and the heating wire 6 is inserted into the mounting hole 41.

Since the width of the first connecting portion 31 is large, the stability of the connection can be ensured. The other end of the second connecting portion 32 is connected to the fixing rod 4, and has the same thickness as the fixing rod 4, ensuring the aesthetics of the connection. At the same time, since the width of the second connecting portion 32 is small, the overall weight can be reduced.
