Description

Technical Field

[0001] The utility model relates to the technical field of plastic film blowing machines, in particular to a plastic film blowing machine with a waste material recycling mechanism. Background Art

[0002] Plastic film blowing machine is a kind of equipment that heats and melts plastic particles and then blows them into thin films. This kind of film can be widely used in light and heavy packaging of various fresh fruits, meat products, pickles, fresh milk, liquid beverages and medical supplies due to its good barrier properties, freshness preservation, moisture resistance, frost resistance, oxygen isolation and oil resistance.

[0003] Although the traditional plastic film blowing machine has achieved certain results in the production process, there are still some problems. First, a large amount of waste will be generated in the production process. These wastes not only waste resources but also increase production costs.

No less than ten air outlet holes are provided on the cooling pipe. The collecting roller is located on the right side of the cooling pipe, and a collecting motor is provided on the collecting roller.

[0015] Through the above technical solution, the opening of the air outlet makes it easy to discharge the cold air in the cooling tube, so as to cool down the finished plastic film on the surface of the cooling tube. By starting the receiving motor, the receiving roller can be driven to rotate to realize the winding of the plastic film.

[0016] Compared with the prior art, the beneficial effects achieved by the utility model are:

Under the action of the air holes and the vent pipe, the waste in the rectangular cover can be sucked into the recycling box and fall into the drawer in the recycling box. By pulling out the drawer, the waste in the plastic film blowing process can be recycled.

[0018] Second, the utility model winds the finished plastic film on the surfaces of two cooling tubes in sequence, and finally winds it on a receiving roller for winding. During the winding process, the air cooler is turned on, and cold air is poured into the cooling tube through the connection of the connecting tube, and discharged through the air outlet holes on the cooling tube, so as to cool down the plastic film on the surface of the cooling tube, which is beneficial to the subsequent winding of the plastic film.
