Abstract

The invention discloses a shearing roll device for drawing films. The device comprises a left shearing roll, a right shearing roll and a supporting frame; the left shearing roll and the right shearing roll are mounted on the supporting frame; the left shearing roll and the right shearing roll both comprise upper rolls, lower rolls, upper roll supporting rods, fixed supports and rotary cylinders; the upper rolls are fixed on rotating shafts of the rotary cylinders through the upper roll supporting rods; the lower rolls are fixed on the fixed supports; the rotary cylinders are mounted on the fixed supports. The shearing roll device for drawing the films, disclosed by the invention, is applied to flattening films in the drawing or pulling process of plastic films, has the advantages that multiple defects are overcome through the invention of the shearing roll and the labor intensity is reduced and also has the advantages of simple structure, easy machining and manufacturing, low manufacturing cost, simple and convenient operation, long service life and simple operation.

Description

The cut roll device of oriented film

Technical field

The present invention relates to a kind of cut roll device of oriented film.

Background technology

Prior art, in plastics machinery evolution, plastic tensile film occupies an important position always, and the flattening of plastic tensile film uses with certain medium-altitude spread rolls or roller (guide) apron always, its complex structure, and installation weight is large, and operation regulates inconvenient.

Summary of the invention

The object of this invention is to provide a kind of being suitable between film thickness 0.01 ~ 0.12mm, the cut roll device of the oriented film stretching or draw can be realized.

The technical scheme that the present invention is adopted for achieving the above object is: a kind of cut roll device of oriented film, comprise left cut roll, right cut roll and bracing frame, described left cut roll and right cut roll are arranged on bracing frame, described left cut roll and right cut roll include top roll, lower roll, top roll pole, fixed bearing and rotary cylinder, described top roll is fixed in the rotating shaft of rotary cylinder by top roll pole, described lower roll is fixed on fixed bearing, and rotary cylinder is arranged on fixed bearing.

Composition folder film gap between described top roll and lower roll.

Described top roll and lower roll include roll surface, antifriction-bearing box and center shaft, are supported between described roll surface and center shaft by antifriction-bearing box.

Described roll surface is the roll surface of axial-rotation.

Described roll surface adopts quality of rubber materials.

The cut roll device of a kind of oriented film of the present invention, the film be applied in the stretching of plastic sheeting or distraction procedure flattens function, the invention of cut roll overcomes shortcomings, its structure is simple, and processing and manufacturing is easy, low cost of manufacture, easy and simple to handle, reduce labour intensity, long service life, simple to operate.

Detailed description of the invention

As shown in Figures 1 to 4, the cut roll device of oriented film, comprise left cut roll 1, right cut roll 2 and bracing frame 3, left cut roll 1 and right cut roll 2 are arranged on bracing frame 3, left cut roll 1 and right cut roll 2 include top roll 4, lower roll 5, top roll pole 6, fixed bearing 7 and rotary cylinder 8, top roll 4 is fixed in the rotating shaft of rotary cylinder 8 by top roll pole 6, lower roll 5 is fixed on fixed bearing 7, rotary cylinder 8 is arranged on fixed bearing 7, the cut roll device of oriented film of the present invention, left cut roll 1 and right cut roll 2 are arranged on bracing frame 3, the film of coming from upstream is by reaching the effect of flattening after left cut roll 1 and right cut roll 2, enter upstream device, top roll 4 is fixed in the rotating shaft of rotary cylinder 8 by top roll pole 6, and lower roll 5 is fixed on fixed bearing 7 motionless, and the axis of rotation of rotary cylinder 8 drives top roll 4 action, completes the adjustment of opening between top roll 4 and lower roll 5, closed and roll gap size, when the film that upstream is come enters into cut roll, top roll 4 is in open mode, after film enters roll gap, rotary cylinder 8 action, top roll 4 is pressed onto on the roll surface of lower roll 5, then adjusts the air pressure of rotary cylinder, make film obtain certain spreading in stretching or distraction procedure, because roll surface 9 adopts top-quality rubber material, have certain elasticity and degree of finish, and adopt antifriction-bearing box 10 to support between roll surface 9 and center shaft 11, roll surface 9 has the function of axial-rotation, and film during downstream transport, does not damage film between roll gap, this construction profile is small and exquisite, and processing and fabricating is easy, obvious to the flattening function of film, the present invention relates to plastic sheeting industry, the film be applied in the stretching of plastic sheeting or distraction procedure flattens function, and the invention of cut roll overcomes shortcomings, and its structure is simple, processing and manufacturing is easy, low cost of manufacture, easy and simple to handle, reduce labour intensity, long service life, simple to operate.
