Abstract
The utility model discloses an apparatus for producing biaxially oriented plastic film, which comprises a film extruding apparatus, a pulling tow attachment, a cooling means, a platform wrap-up and an electrical control gear. The apparatus is characterized in that the upper part of the pulling tow attachment is provided with a rotating heating apparatus for biaxially orienting film; therefore, the pipe film is first heated to the stretchable temperature at high springy type and the pipe tube shape film is charged with compression air by pipe film blow swollen method. With a larger blow swollen ratio the lengthwise and transverse pulling and forming of the film are conducted. The transverse pulling treatment and the transverse pulling apparatus are saved; therefore, the producing art is simplified and the apparatus price is reduced.
Description
Technical field
The utility model relates to technical field of plastic, more specifically to a kind of equipment of producing bidirectional stretching plastic film.
Background technology
Existing bidirectional stretching plastic film, after blowing or curtain coating obtain certain thickness sheet film, make film carry out abundant cross directional stretch, this equipment price costliness, complex process, product cost height through the cross directional stretch device.
Summary of the invention
The purpose of this utility model provides the equipment that a kind of technology is simply produced bidirectional stretching plastic film.
The equipment of production bidirectional stretching plastic film provided by the utility model is design like this: it comprises the film extrusion device, stretching and drawing device, cooling device, platform wrap-up and electrical control gear etc. is characterized in that: be provided with the rotatable heater that is used for the film biaxial tension on stretching and drawing device top.
The utility model is owing to be provided with the rotatable heater that is used for the film biaxial tension on stretching and drawing device top, but therefore can make periosteum be heated to the draft temperature of elastomeric state earlier, use the periosteum inflation method then, in socket shape film, charge into compressed air, with bigger blow-up ratio, make film carry out vertical and horizontal and stretch, finalize the design.No longer need cross directional stretch to handle, also no longer need original cross directional stretch device, therefore simplified production technology, reduced equipment price.

The specific embodiment
The equipment of production bidirectional stretching plastic film provided by the utility model is design like this, it comprises film extrusion device, stretching and drawing device, cooling device, platform wrap-up and electrical control gear etc., it is characterized in that: be provided with the biaxial tension rotatable heater 11,12 that is used for the film biaxial tension on stretching and drawing device top.
Below in conjunction with accompanying drawing use of the present utility model is described further:
After stock was entered by hopper 1, through extruder 2 fusings, extrusion plastic, the film head connect the plastics introduction bubble pipe die head 4 that cover 3 mixes the extruding machine fusing, and bubble pipe die head 4 is the film tubulose with the molten plastic extrusion molding.By the first folder rod 6 the plastic foil pipe is drawn by die head, and control thickness, quicken film pipe cooling and shaping through vane 5 coolings and cooling water tank 7, then through carrying roller 8,9 press from both sides rod 10 by second draws to pylon top, again by rotatable heater 11, but 12 are heated to the draft temperature of elastomeric state, this moment is by charging into an amount of air in the periosteum, stretch through the anxious step by step speedup of longitudinal traction roller 17, and outwards stretch by horizontal both sides at same space-time, and control vacuolar membrane thickness, rotation cooling vane 13,14 make the evenly cooling of film bubble, typing, sizing dish 15 stable bubble diameters, guiding clamping plate 16 stable bubble shapes, the film bubble is flattened along certain angle, introduce traction nip rolls 17, enter thermal finalization then, cutting edge film breaking unit 18 breaks the film bubble and is diaphragm, or cut out whole film limit, auxiliary nip rolls 21 increases cutting edge tension force, make the edge after cutting smooth, diaphragm is respectively through carrying roller 19,20 are sent to wrap-up 22, and wrap-up 22 batches plastic sheeting, and cutting edge blower 23 blows away the cutting edge cutter and carries the featheredge of cutting.
Also can on hauling machine support 25, establish a rotary platform 24, transmission device by rotary platform 24 belows makes rotary platform 24 slowly with 360 degree rotations, thereby drives clamping plate, nip rolls and wrap-up rotation, makes the film cooling evenly, can when batching plastic sheeting, batch smooth.
Claims (2)
