A film blowing machine with stable tension function

Abstract

The invention provides a film blowing machine with a tension stabilizing function. A foam stabilizing device capable of moving up and down and a tension stabilizing device are arranged above a film blowing device; a foam stabilizing frame comprises a support; a foam stabilizing framework is fixed to the inner wall of the support; the support is provided with a guiding column; the foam stabilizing framework moves up and down along the guiding column; a traction device sequentially comprises an inverted-Y-shaped frame and a traction roller from bottom to top; and the lower ends of two side wings of the inverted-Y-shaped frame can oppositely move and are located above the foam stabilizing framework. The tension stabilizing device guarantees that winding is compact. Compared with the prior art, by arranging the foam stabilizing frame capable of moving up and down and arranging a baffle capable of adjusting the distance in the horizontal direction on the foam stabilizing frame, film foam of different heights and diameters can be stabilized and limited; by means of the guiding column and a horizontal threaded rod, movement of the foam stabilizing frame and the baffle is easily achieved, and operation is convenient and easy; and in order to adapt to foam stabilizing frames of different sizes, the two side wings of the inverted-Y-shaped frame of the film blowing machine with the tension stabilizing function can also move, and therefore the film foam of different diameters can be extruded.

Description

technical field

[0001] The invention relates to the technical field of plastic film production, in particular to a film blowing machine with a stable tension function. Background technique

[0002] At present, packaging bags are widely used in daily life and work due to their convenience and simplicity in use and carrying. Plastic products include polyethylene plastic products, polypropylene plastic products and polyvinyl chloride plastic products. These plastic products can not only protect products and facilitate transportation, but also promote sales and beautify products.

[0003] The plastic film production equipment of prior art is basically blown film, printing, mutually independent machine. In the production process, the process is complicated, and the film roll will be deformed or damaged during the handling process, resulting in unnecessary waste. The obsolescence of equipment functions leads to defects in low production efficiency and poor film quality. Conte...
