Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a film absorbing mechanism of a digital printing machine. Background Art

[0002] In the thermal transfer process of the digital printing machine, the transferred transfer film needs to be cut off, and then the new transfer film is used for the transfer of the next batch of products. However, after the transfer is completed, the film clamping tensioning mechanism and the tensioning mechanism connecting the film roll will be loosened, but the film clamping tensioning mechanism only moves in the vertical direction, and the film loses the lateral tensioning force, but at this time the clamp on the film clamping tensioning mechanism is still in the clamping state, so the transfer film on the platform will not move in its length direction, but because the tensioning mechanism is loosened, the unwinding mechanism can move, that is, the transfer film between the platform and the unwinding mechanism may fall, and the film cutting device is set at this place to cut the transfer film. If the transfer film falls too much, it is not only inconvenient for the film cutting mechanism to cut, but also may cut off more untransferred film, resulting in greater waste. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a film suction mechanism of a digital printing machine, which can clamp the transfer film in the film cutting stage, ensure the smooth film cutting, and avoid the waste caused by cutting off unused transfer film.

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

[0005] A film suction mechanism for 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, the lifting mechanisms are provided with a suction cup fixing seat, and the suction cup fixing seat is provided with a suction cup for adsorbing a transfer film.

[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 suction cup fixing seat.

[0007] Preferably, it comprises a cylinder fixing seat, and the lifting mechanism is connected to the frame via the cylinder fixing seat.

[0008] Preferably, a support tube is connected between the two suction cup fixing seats.

[0009] Preferably, the support tube comprises a support surface, and the support surface is horizontal.

[0010] Preferably, the support tube is in the shape of a square column, and the upper surface of the support tube is the support surface.

[0011] Preferably, the suction cup fixing seat includes a connecting rod and a mounting rod, one end of the connecting rod is connected to the lifting mechanism, the other end of the connecting rod is connected to the support tube, one end of the mounting rod is connected to the middle part of one side of the connecting rod, and the suction cup is arranged at the other end of the mounting rod.

[0012] Compared with the prior art, the film suction mechanism of a digital printing machine in the embodiment of the utility model has the following beneficial effects: by arranging it between the unwinding mechanism and the film cutting mechanism, a lifting mechanism is arranged, and a suction cup fixing seat is arranged on the lifting mechanism, and a suction cup for adsorbing the transfer film is arranged on the suction cup fixing seat. When the transfer is completed and the film needs to be cut, the lifting mechanism drives the suction cup to move up and adsorb the transfer film. At the same time, under the action of the film clamping and tensioning mechanism, the film to be cut is completely tightened in the vertical direction, thereby avoiding the transfer film from falling at the position of the film cutting mechanism, ensuring the smooth film cutting, and avoiding the waste caused by cutting off the unused transfer film.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] like Figure 1 As shown, a film suction mechanism of a digital printing machine in a preferred embodiment of the utility model is arranged on the frame of the printing machine and is located between the unwinding mechanism and the film cutting mechanism, including a lifting mechanism relatively arranged on both sides of the frame, a suction cup fixing seat 2 is provided on the lifting mechanism, and a suction cup 5 for adsorbing the transfer film is provided on the suction cup fixing seat 2.

[0019] The film suction mechanism of the digital printing machine based on the above technical features is arranged between the unwinding mechanism and the film cutting mechanism, and at the same time, a lifting mechanism is arranged, and a suction cup fixing seat 2 is provided on the lifting mechanism, and a suction cup 5 for adsorbing the transfer film is provided on the suction cup fixing seat. When the transfer is completed and the film needs to be cut, the lifting mechanism drives the suction cup 5 to move up and absorb the transfer film. At the same time, under the action of the film clamping and tensioning mechanism, the film to be cut is completely tightened in the vertical direction, thereby avoiding the transfer film from falling at the position of the film cutting mechanism, ensuring the smooth film cutting, and avoiding the waste caused by cutting off unused transfer film.

[0020] After the cutting is completed, the suction cup 5 is separated from the transfer film and descends under the action of the lifting mechanism.

[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 suction cup fixing seat 2.

[0022] In this embodiment, in order to further clamp the transfer film and improve the film cutting effect, a support tube 4 is connected between the two suction cup fixing seats 2, that is, the two suction cups 5 adsorb the edges of the transfer film, and the support tube 4 supports the middle part of the transfer film, thereby preventing the transfer film from falling between the two suction cups 5, further ensuring the clamping effect, and thus improving the film cutting effect. At the same time, in order to prevent the support tube 5 from causing damage to the surface of the transfer film, the support tube 5 includes a support surface, and the support surface is horizontal. When specifically set, the support tube 5 can be set to a square column shape, and can be directly made of a square tube. The upper surface of the square tube is the support surface, and the support is simple and convenient. Of course, the support surface can also be set to an arc shape and directly made of a round tube.

[0023] In this embodiment, the suction cup fixing seat 2 includes a connecting rod 21 and a mounting rod 22, one end of the connecting rod 21 is connected to the lifting cylinder 1, the other end of the connecting rod 21 is connected to the support tube 4, and one end of the mounting rod 22 is connected to the middle of one side of the connecting rod 21, that is, the connecting rod 21 and the mounting rod 22 form a T shape. The suction cup 5 is arranged on the upper surface of the other end of the mounting rod 22.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
