[0022] In addition, the pressure roller 5 of the utility model includes a sliding column 51 slidably connected to the inside of the sliding hole 22, and the top of the sliding column is provided with a limiting flange 54 for preventing the sliding column from detaching from the cross plate. The pressure roller 5 is rotatably connected to the bottom of the two sliding columns 51 and is passed between the heat sealing belts 4. The sliding column 51 is provided with a thrust spring 53 that presses the pressure roller 5 to the bottom. Under the action of the thrust spring 53, the roller column 52 of the pressure roller 5 can abut against the heat sealing belt 4, ensuring that during heat sealing, the heat sealing belt 4 can be in close contact with the heat sealing plate 7 under the action of the pressure roller 5, thereby effectively performing a heat sealing process on the film.
