The terms "vertical", "horizontal", "left", "right" and the like used in this paper are only for illustrative purposes.

[0025] As Figures 1 to 3 shown, the plastic film blowing machine of the present application comprises: a box 1, a film collector 8 is fixedly installed in the box 1; a film blowing machine body 2 is fixedly installed on the box 1; a cleaning mechanism for cleaning the plastic film; a treatment mechanism for treating the gas generated by film blowing.

[0026] The cleaning mechanism comprises a lower extrusion roller 3 installed in the box 1 through a mounting bracket, an upper extrusion roller 4 arranged above the lower extrusion roller 3, a moving assembly for moving the upper extrusion roller 4, the moving assembly comprising a movable frame 6 slidingly installed on the box 1, a cylinder 7 for moving the movable frame 6, a movable plate 5 fixedly installed at the bottom of the movable frame 6, the upper extrusion roller 4 being installed at the bottom of the movable plate 5 through a mounting bracket II, and rubber layers being fixedly installed on the outer edges of the upper extrusion roller 4 and the lower extrusion roller 3.

[0027] When the film blowing machine body 2 is started to blow film, the cylinder 7 is started to contract, the movable frame 6 is moved downward by the cylinder 7, the movable plate 5 is moved downward by the movable frame 6, so that the upper extrusion roller 4 approaches the lower extrusion roller 3, thereby adjusting the film forming thickness according to the requirement, and the film can be wound by starting the film winding machine 8.

[0028] Since the rubber layers are fixedly installed on the outer edges of the upper extrusion roller 4 and the lower extrusion roller 3, the dust on the surface of the film can be adsorbed and cleaned, thereby ensuring the cleanliness of the film during winding.

[0029] The processing mechanism comprises a fixed shell 9 fixedly installed in the box 1, an air inlet opening arranged on the fixed shell 9, a sealing gasket 10 for sealing the air inlet opening, the sealing gasket 10 being fixedly installed on the top of the movable plate 5, an air outlet assembly for discharging the gas in the box 1, the air outlet assembly being provided with two groups which can be used alternately according to the requirement, a purification assembly for purifying the gas discharged from the box 1, the air outlet assembly comprising an air outlet pipe 15 plug-in installed on the box 1, the air outlet pipe 15 being a square pipe, a fan 16 and a dustproof net 17 fixedly installed in the air outlet pipe 15, the purification assembly comprising an activated carbon plate 18 for purifying the gas discharged from the air outlet pipe 15, the activated carbon plate 18 being slidingly installed in the air outlet pipe 15, and a mounting unit for mounting the activated carbon plate 18, a motor 11 fixedly installed on the box 1, a circular plate 12 fixedly installed on the output shaft of the motor 11, a circular opening arranged on the circular plate 12, an extrusion block 13 fixedly installed on the circular plate 12, a touch switch 14 fixedly installed in the fixed shell 9, and the touch switch 14 being electrically connected with the fan 16.

[0030] When the film blowing machine body 2 is not used or maintained, the sealing gasket 10 seals the air inlet opening, thereby avoiding the gas in the box 1 from escaping and polluting the environment.

[0031] When the movable plate 5 moves downward, the sealing gasket 10 is driven to move downward, so that the sealing gasket 10 no longer seals the air inlet opening. At this time, the motor 11 is started to drive the circular plate 12 to rotate. When the circular opening on the circular plate 12 is aligned with one of the air outlet pipes 15, the pressing block 13 presses the corresponding micro switch 14, so that the corresponding fan 16 is started. At this time, the fan 16 blows air upward, so that the gas in the box 1 is sequentially discharged through the air inlet opening, the circular opening and the air outlet pipe 15.

[0032] Through the setting of the activated carbon plate 18, the waste gas generated during film blowing can be purified, thereby achieving the effect of environmental protection and avoiding harm to the physical and mental health of the operator.

[0033] Through the setting of the dust screen 17, dust and other foreign matters are prevented from falling into the air outlet pipe 15, thereby preventing damage to the fan 16 and affecting use.

[0034] When the activated carbon plate 18 in one air outlet pipe 15 needs to be replaced after long-term use, the motor 11 is started to drive the circular plate 12 to rotate, so that the circular opening is aligned with another air outlet pipe 15, and the pressing block 13 presses the corresponding micro switch 14. At this time, the corresponding fan 16 is started, and the gas in the box 1 can be discharged through another air outlet pipe 15. At this time, the operator can replace the used activated carbon plate 18. Therefore, the application can switch the air outlet assembly for use according to the use condition, so that the activated carbon plate 18 can be replaced without stopping the machine, thereby improving the work efficiency.

[0035] It is supplemented here that when the film blowing machine body 2 is not used, the motor 11 drives the circular plate 12 to rotate, so that the circular opening is not aligned with any air outlet pipe. At this time, the circular plate 12 plays a role of closing the bottom end of the air outlet pipe 15, thereby preventing the gas from being discharged from the box 1 and polluting the environment.

[0037] When the activated carbon plate 18 is replaced, the sliding plate 22 is pulled to drive the plug-in rod 24 to move, so that the plug-in rod 24 is separated from the plug-in hole. At this time, the mounting plate 19 is pulled to drive the activated carbon plate 18 to move out of the air outlet pipe, so that the activated carbon plate 18 can be quickly replaced.

[0038] Compared with the bolt dismounting mode in the prior art, the mode of replacing the activated carbon plate 18 in the application is faster, simpler to operate, does not need special tools for dismounting, and improves the convenience of replacement.
