Description

Technical Field

[0001] The utility model relates to an air cooling device for plastic film, in particular to an air cooling device for discharging plastic film, and belongs to the technical field of plastic film processing devices. Background Art

[0002] Plastic film, also known as plastic film, is a widely used packaging material. It is primarily made of polymers such as polyethylene (PE), polyvinyl chloride (PVC), and polypropylene (PP), and is processed into a film through a series of processes.

[0003] During the processing of plastic film, a plastic film unloader is needed for processing. The plastic film unloader is a device widely used in the field of plastic film processing. Its main function is to unload the rolled plastic film smoothly and accurately for use in subsequent processes.

[0004] After the plastic film is blown out by the film blowing machine, it is a continuous long strip and is discharged with high temperature. The high-temperature plastic film cannot be directly reeled up without cooling when it is discharged. The existing cooling method mostly uses an air cooling device to cool it. The existing air cooling device is usually fixed at the film discharge end of the plastic film unloader, and uses a fan to blow and cool the plastic film. However, during the air cooling, since the plastic film is soft and thin, strong wind may blow the plastic film into shape and affect the later collection. At the same time, the plastic film may also be blown to pieces. Utility Model Content

[0007] Furthermore, the drum is a hollow drum, and the air cooling assembly includes a connecting ring threadedly connected to one end of the drum, a support rod arranged in the connecting ring, and a cooling fan supported and fixed by the support rod.

[0008] Furthermore, the ventilation hole is a trumpet-shaped structure, and the large-diameter opening of the ventilation hole is located on the surface of the drum; auxiliary handles are provided on both sides of the support rod, and a sealing plate is magnetically adsorbed by the connecting ring.

[0009] Furthermore, handles are provided on both sides of the outer surface of the sealing plate, a plurality of foreign matter filtering holes are provided on the sealing plate, a magnetic hole is provided on the connecting ring, and a magnetic rod is provided on the sealing plate to be magnetically attracted to the magnetic hole.

[0010] Furthermore, the driving mechanism includes two first gears arranged at one end of the two rollers and a second driving motor arranged on the outside of the support frame, the two first gears are meshed and connected, and the output end of the second driving motor is provided with a second gear meshed and connected to the first gear.

[0011] Furthermore, a slide groove is vertically opened on the support frame, a slider is slidably connected in the slide groove, and both ends of the tensioning roller are rotatably connected to the two sliders respectively.

[0012] Furthermore, a third drive motor is provided on the upper end surface of one of the support frames, and an output end of the third drive motor passes through the slide groove and is connected to a screw rod threadedly connected to the slider.

[0013] Compared with the prior art, the present invention has the following beneficial effects:
