[0002] Application CN202322475863.1 discloses a lower film positioning mechanism for a three-dimensional transparent film packaging machine, which includes an air suction plate. Transparent film limiting pressure rollers are provided at both the upper and lower ends of the air suction plate. A transparent film limiting pressure roller fixing seat is provided on the air suction plate. The transparent film limiting pressure roller is connected to the transparent film limiting pressure roller fixing seat via a connector, and the transparent film limiting pressure roller is rotatably connected to the connector and abuts against the top surface of the air suction plate. In the above technical solution, the air suction plate is located on both sides of the transparent film and below the film knife assembly. The defect of this structure is that, due to the lack of fixation at the cutting point, the transparent film is not cut evenly during cutting, resulting in inaccurate sealing and vertical floating, thus causing defective packages.

The film blade roller is provided on the frame and is arranged opposite to the film fixing rod, and a rolling film is provided on the film blade roller. The rolling film blade and the fixed film blade cooperate to cut the transparent film.

[0006] In this application, the transparent film is output along the surface of the diaphragm blade guide plate. At the same time, air is drawn in by the vacuum generator, so that the transparent film can be adsorbed on the surface of the diaphragm blade guide plate and conveyed forward. During cutting, the cut end of the transparent film is fixed, thereby making the cut smoother and without deviation.

[0007] Preferably, the first suction port is connected to the vacuum generator via a flexible pipe.

[0008] Preferably, the flexible conduit is disposed on the rear end face of the blade fixing rod.

[0009] Preferably, a guide plate is also provided at the top of the blade film fixing rod.

[0010] Preferably, the diaphragm guide plate is fixed on the middle part of the diaphragm fixing rod.

[0011] Preferably, the rear end of the blade fixing rod is provided with three rear air intake channels, and the three rear air intake channels are connected to three front air intake channels to form a plurality of first air intake holes.

[0012] Preferably, the diaphragm blade guide plate is provided with three second suction holes that communicate with the suction pre-channel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In this application, the transparent film is output along the surface of the diaphragm blade guide plate. At the same time, air is drawn in by the vacuum generator, so that the transparent film can be adsorbed on the surface of the diaphragm blade guide plate and transported forward. When cutting, the cut end of the transparent film is fixed, which makes the cut smoother and does not deviate. Attached Figure Description
