[0005] To achieve the above purpose, the utility model provides the following technical solution: a film pressing device for a bag making machine, comprising:

[0006] An equipment box, wherein a pressing platform is provided on the top of the equipment box;

[0007] A first hydraulic rod, wherein the first hydraulic rod is installed on both sides of the top of the equipment box, and the movable end of the first hydraulic rod is fixedly connected to a mounting frame, and a hollow structure is opened inside the mounting frame;

[0008] Moving blocks are slidably installed on both left and right sides of the mounting frame, and a pressing frame is slidably installed up and down inside the moving blocks.

[0009] Preferably, an adjusting rod is rotatably mounted inside the mounting frame, and an outer surface of the adjusting rod is a bidirectional threaded structure.

[0010] Preferably, the connection between the adjusting rod and the moving block is a threaded connection, and a spring for returning the pressing frame downward is provided at the bottom of the moving block.

[0011] Preferably, a second hydraulic rod is installed on the bottom side of the top of the equipment box, and a hot pressing plate is installed on the movable end of the second hydraulic rod.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the film pressing device of the bag making machine is convenient for adjusting the position of the pressing structure, so as to facilitate pressing of films of different sizes, and the device has strong flexibility;

[0013] Place the film on the pressing table, adjust the position of the pressing frame according to the size of the film, turn the adjusting rod to drive the moving block to move left and right, so that the moving block drives the pressing frame to adjust the position. After the position of the pressing frame is adjusted, the first hydraulic rod drives the mounting frame to move downward so that the pressing frame squeezes and fixes the film. The spring is set to make the pressing frame have a buffering property to prevent the pressing frame from squeezing and damaging the film. After the film is fixed, the second hydraulic rod drives the hot pressing plate to move downward to hot-press the film. The hot pressing plate can be replaced according to the size of the film.
