Description

TECHNICAL FIELD

[0001] The utility model relates to an improvement of a transverse supporting rod used on a herringbone plate or an inserted edge plate of a film blowing machine, in particular to a rolling conveying supporting roller for a film blowing machine and a special ABS roller, which is suitable for being installed on a herringbone plate, an inserted edge plate or a bubble stabilizer of a film blowing machine. BACKGROUND

[0002] The film blowing machine is a general machine for producing film, which comprises a frame, an extruder, a blower, a die head, a bubble stabilizer, a traction device, a herringbone plate and a winding device. The film blowing machine melts plastic particles, blows out a cylindrical film through the die head and the air ring of the film blowing machine, and then the film is pulled and flattened by the herringbone plate of the traction device, so that the film changes from a cylindrical shape to a sheet shape. Finally, the film is wound by the winding device. If the film with an inner folded edge is produced, an inserted edge plate is installed on the side of the herringbone plate. The inserted edge plate pushes into the center of the film to form an inward folded edge structure. In this way, the flattened and wound film with an inner folded edge structure is obtained in cooperation with the herringbone plate. In the herringbone plate, the inserted edge plate or the bubble stabilizer of the film blowing machine, a supporting frame and a transverse supporting rod are provided. The transverse supporting rod is evenly arranged between the vertical fixed rods of the supporting frame, so as to stabilize the shape of the film and smoothly convey the film. The transverse supporting rod is a smooth straight rod, the two ends of which are fixed on the supporting frame, and the outer wall of the film is attached to the outer wall side of the transverse supporting rod for upward conveying. However, the sliding friction between the transverse supporting rod and the film generates a large friction force, which makes the film not smooth and uniform, and causes the film to shake. In the subsequent film traction, the winding is not beautiful, the product quality is reduced, and the film is prone to wrinkles and unevenness, which leads to poor product appearance and low yield. In order to solve this problem, a sleeve is provided on the transverse supporting rod. Although the sleeve can reduce the friction force, the sleeve is relatively long, the film is in a cylindrical shape, and the friction force between the sleeve and the film is not uniform in the axial direction, which still causes the film to have wrinkles and unevenness during the winding process.
