Description

Technical Field

[0001] The utility model relates to the technical field of film blowing machines, in particular to a roller cleaning mechanism and a film blowing machine with the same. Background Art

[0002] Film blowing machines heat and melt plastic pellets before blowing them into thin films. There are many types of film blowing machines, including those for PE, POF, and PVC. Using fresh pellets produces fresh material with uniform color, clean texture, and excellent bag stretch. The process involves melting the plastic pellets, filtering the molten plastic through the die to remove impurities, then exiting the die head, cooling it through an air ring, inflating it, passing it through a herringbone frame, pulling rollers, and finally winding it up, completing the entire process from plastic pellets to film.

[0003] The Chinese patent with announcement number CN213972558U discloses a new type of film blowing machine that is easy to clean. A cooling box is fixedly welded between the two groups of connecting columns. A gap is opened on the outer wall of one side of the film blowing machine body for film to pass through. A first support seat and a second support seat are respectively provided on the surface of the other side of the base. A guide roller is rotatably mounted on the first support seat, and a collecting roller is rotatably mounted on the second support seat. A fan is fixedly mounted on the lower surface of one side of the base, and the air outlet of the fan is respectively connected to a first duct and a second duct. One end of the first duct and the second duct both pass through the base and extend to the bottom of the guide roller and the bottom of the collecting roller respectively. The upper end of the first duct and the upper end of the second duct are both fixedly connected to the main air pipe, and a nozzle is fixedly mounted on the outer wall of the main air pipe. The utility model cleans the equipment more evenly without causing damage to the equipment, thereby extending the service life of the equipment and ensuring production quality.

[0004] However, the above technical solution has the following shortcomings: the surface of the guide roller is cleaned by high-pressure airflow, and the foreign matter blown off is diffused in the air around the equipment and cannot be collected and processed, which not only affects the environment of the workplace, but also the foreign matter falls on the film and easily affects the quality of the finished film.
