Abstract
The invention discloses an oblique stretching-manufacturing process of a film. The manufacturing process comprises the following steps: (1) fixing the film on a clip at an entrance of a stretching machine, and conveying the film by virtue of a chain transmission system; (2) conveying the clip along rails to drive the film to enter a preheating region, so as to preheat the film to an expected temperature; (3) moving the preheated film along the rails, obliquely stretching the film due to the difference between the rails on two sides when the rails begin to be bent and widened, conveying the stretched film into a shaping region, and carrying out stretching shaping on the film; (4) conveying the shaped film along the rails, simultaneously cooling the film, and opening the clip to release the film when arriving the terminals of the rails; and (5) introducing the released film to enter a subsequent procedure by virtue of a guiding roll, so as to finish the whole stretching-manufacturing process. The oblique stretching-manufacturing process has the advantages of high reliability, simple process, oblique stretching form, high production efficiency, high yield, few leftover materials, oblique tensile strength and the like.
Description
Technical field
The present invention relates to field of thin film fabrication, particularly relate to a kind of film oblique extension manufacturing process.
Background technology
Film stretching is a kind of common method of manufacturing film, lower than film fusing point, higher than under vitrification point to carrying out compared with thick film sheet laterally or longitudinal stretching, under tensioning state, carry out thermal finalization, cold formed processing, there is intensity high, shock-resistant, cold-resistant heat-resisting, improve transparency, improve aging and improve the advantages such as obstructing capacity, existing film cross directional stretch is to utilize track expansion to realize the stretching of film, longitudinal stretching utilizes the speed discrepancy between roller to realize film stretching, because cross directional stretch and longitudinal stretching make stretched film only have tensile strength at draw direction, often need draw and indulge and draw processing through horizontal simultaneously, cause production waste many, output is few, production stage is many, tensile strength is inhomogeneous.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of film oblique extension manufacturing process, by utilizing track bad student to produce oblique pull film, become the curved track that broadens by use and adapt to different Production requirements, have that reliability is high, technique is simple, oblique extension, production efficiency is high, output is large, leftover pieces are few, flat appearance, have the advantages such as oblique tensile strength.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of film oblique extension manufacturing process is provided, comprises: film is fixed on entering on clip of stretching-machine guide rail by (1), and by chain drive system transmission;
(2) clip is advanced along track, drives film to enter preheated zone, makes film be preheated to desired temperature;
(3) film after preheating moves along drawing trajectory, and when drawing trajectory starts bending while broadening, due to the travel distance difference of two siding tracks, film is by oblique extension, enters territory, shaping area after completing stretching, makes film complete drawing and setting;
(4) film after sizing, with drawing trajectory transmission, carries out coolingly simultaneously, and during to track terminal, folder is opened, and discharges film;
(5) film after release enters subsequent technique through deflector roll.
In a preferred embodiment of the present invention, described drawing trajectory corner is the curved track that broadens.
In a preferred embodiment of the present invention, described chain conveyor track has 2, and described chain conveyor track is annular.
The invention has the beneficial effects as follows: film oblique extension manufacturing process of the present invention is by utilizing track bad student to produce oblique pull film, become the curved track that broadens by use and adapt to different Production requirements, there is the advantages such as reliability is high, technique simple, oblique extension, production efficiency is high, output is large, leftover pieces are few, flat appearance.

Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of film oblique extension manufacturing process, comprising: film is fixed on to entering on clip of stretching-machine guide rail, and by chain drive system transmission; Clip is advanced along track, drives film to enter preheated zone, makes film be preheated to desired temperature; Film after preheating moves along drawing trajectory, and when drawing trajectory starts bending while broadening, due to the travel distance difference of two siding tracks, film is by oblique extension, enters territory, shaping area after completing stretching, makes film complete drawing and setting; Film after sizing is with drawing trajectory transmission, carries out coolingly simultaneously, during to track terminal, opens and closes folder and opens, and discharges film; Film after release enters subsequent technique through deflector roll.
Described drawing trajectory corner is the curved track that broadens, and ensures that draw direction angle is 45 °.
Described chain conveyor track has 2, and described chain conveyor track is annular, and chain is back and forth moved.
The beneficial effect of film oblique extension manufacturing process of the present invention is:
One, by utilizing track bad student to produce oblique pull film, production efficiency is high, operation is simple;
Two, become the curved track that broadens by use and adapt to different Production requirements;
Three, have that reliability is high, technique is simple, oblique extension, production efficiency is high, output is large, leftover pieces are few, flat appearance, has the advantages such as oblique tensile strength.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
