Abstract
The invention discloses a film-blowing, cooling and drawing device. The film-blowing, cooling and drawing device comprises a guide roller rack, a drawing clamping roller and a rotation rolling rack, and the above members are orderly connected. A film is gradually compressed by the guide roller rack so that air is discharged, and then is drawn by the drawing clamping roller, and then a film folded position is adjusted by rotation rolling rack adjustment so that air in the film is completely discharged.
Description
Technical field
The present invention relates to a kind of film blown film cooling tractor.
Background technology
Currently available technology, film main production has inflation method; Film laminated method mainly contains following three kinds: extrude compound, have solvent adhesive stick dry laminating, solventless adhesive compound.
For above several complex method, all there is no good hitch structure after film blowout, bring inconvenience to production.
Summary of the invention
For the shortcoming of prior art, the object of this invention is to provide a kind of film blown film cooling tractor.
For achieving the above object, technical scheme of the present invention is: a kind of film blown film cooling tractor, it comprises the guide roller stand, traction nip rolls and the rotation rolling frame that connect successively, film to gradually reduce exhaust through guide roller stand, again through the traction of traction nip rolls folder, then by rotating rolling frame adjustment film folding position, thus the gas in complete drained film.
Described guide roller stand is chevron shaped structure.This rotation rolling frame comprises the nip rolls of multiple distribution in stair staggered.
The present invention compared with prior art tool has the following advantages and beneficial effect:
The present invention adopts one-shot forming to make, and production technology is simple, and have compound fastness good, heat seal strength is high, the simple feature of structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1, a kind of film blown film cooling tractor, it comprises the guide roller stand 3, traction nip rolls 4 and the rotation rolling frame 5 that connect successively, film to gradually reduce exhaust through guide roller stand 3, traction is pressed from both sides again through traction nip rolls 4, then film folding position is adjusted by rotating rolling frame 5, thus the gas in complete drained film.
Described guide roller stand 3 is in chevron shaped structure.This rotation rolling frame 5 comprises the nip rolls of multiple distribution in stair staggered.
This preparation method comprises the following steps:
A. plastic raw materials melt extrudes by extruding unit, enters co-extrusion die head; Extrude the resin material that unit can use various blown film level, thus manufacture one to the different heat-sealable film of three-decker.
B. after melted material is extruded from co-extrusion die head, also upwards draw cooling form film by air inflation, film, after cooling tractor compression exhaust, is flattened by serial deflector roll and nip rolls cooling.
