AI Technical Summary
Technical Problem
In existing cooling devices, dust in the air can easily adhere to the blown film in its molten state before it has fully cooled, leading to a decrease in film quality.
Method used
The dust removal assembly consists of an electrified rubber roller and a leather belt. It attracts dust by friction and charges it, and then cleans the dust with a cleaning component to prevent dust from adhering to the uncooled melt. At the same time, it uses cyclone airflow for uniform cooling.
Benefits of technology
This effectively prevents dust adhesion, improves film quality, and ensures uniform cooling and forming of the film.

Abstract
The application provides a packaging bag forming equipment, which comprises a rack, a winding assembly and a molten material device for hot-melt raw material, and further comprises a film blowing device, a dust removal assembly and a film winding device, the film blowing device is used for blowing and moving the plastic film upwards into the film winding device after the plastic slurry is extruded to form a ring-shaped plastic film; the dust removal assembly comprises a mounting frame, a cleaning assembly and rotating rollers, the rubber rollers are rotatably installed on the mounting frame, the rotating rollers are symmetrically arranged at the upper and lower ends of the mounting frame, the fur belts are arranged on the rotating rollers, the fur belts are in contact with the rubber rollers, and the first driving device for driving the mounting frame to overturn is arranged on the film blowing device; the application can solve the problem that the dust in the air is easily adhered to the film in the molten state which has not been completely cooled under the action of the cooling air flow when the cooling device in the prior art cools the film, thereby reducing the film production quality.
