Abstract
A novel thin film transverse stretching machine comprises two rotary chain tracks; each rotary chain track is provided with a rotary chain, and each rotary chain is provided with clamps; each returning track section is provided with a dedusting cooling channel; each dedusting cooling channel is provided with a gas outlet and high-pressure gas nozzles stretching into the dedusting cooling channel and distributed in a matrix mode, a distance between each adjacent high-pressure gas nozzles is as wide as 1-2 clamps, the high-pressure gas nozzles are vertical to the clamps, and a distance between the high-pressure gas nozzles and the clamps is 2-5 cm. A dedusting cooling device is mounted on each returning track section, so that clamping chip dust adhering to the transverse stretching clamps and small molecules generated in a transverse stretching production process can be effectively removed; and at the same time, the device can effectively reduce a thin film unclamping phenomenon, rapidly lowers the temperature of the returning track section clamps, thereby being convenient for the clamps to perform film-clamping production again at a suitable temperature.
Description
Technical field
The present invention relates to a kind of film transverse stretching machine.
Background technology
Film transverse drawing mill comprises two revolution chain rails, and revolution chain rail is provided with circumversion chain, and circumversion chain is provided with fixture, and two relative rail sections of revolution chain rail are active section, and the rail section in the outside of two revolution chain rails is back rail section.When work, active section fixture can tightly be clamped two edges of sheet material, and be supported on the deflector roll of variable fabric width, by means of two chains folder in the same way, synchronous operation, first sheet material carries out preheating at the preheating section of amplification slightly, in having compared with the drawing zone of large expansion angle, carries out cross directional stretch.The fixture of active section enters back rail section afterwards.
On existing Biaxial Oriented Plastic Film Line, the horizontal folder bits dust that draws fixture clamping film and produce and the horizontal little Molecular Adsorption producing in production process of drawing of film are in fixture jaws, in continuous production situation, easily make contaminated fixture repeatedly pollute TDO, pollute the film of producing, and in follow-up traction wrapup procedure, cause film damage, have a strong impact on film apparent property and optical property; Also can reduce fixture clamping ability, cause the de-folder of film phenomenon, reduce production efficiency etc. simultaneously.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing film transverse stretching machine, the invention provides and a kind ofly can carry out to returning the fixture of rail section the novel thin film transverse stretching machine of cooling and dedusting.
The technical scheme that the present invention solves its technical problem is: a kind of novel thin film transverse stretching machine, bag
Draw together two revolution chain rails, described revolution chain rail is provided with circumversion chain, and described circumversion chain is provided with fixture, and two relative rail sections of revolution chain rail are active section, and the rail section in the outside of two revolution chain rails is back rail section;
In described returning in rail section, be provided with dedusting cooling duct, described dedusting cooling duct is provided with gas outlet, described dedusting cooling duct is provided with the high pressure valve that is matrix distribution stretching in described dedusting cooling duct, distance between adjacent high pressure valve is 1 ~ 2 fixture width, described high pressure valve and described fixture are perpendicular, and the distance between described high pressure valve and fixture is 2 ~ 5cm.
Beneficial effect of the present invention is: by returning rail section installation dust-cleaning and refrigerating mechanism, can effectively remove horizontal folder bits dust and the horizontal little molecule producing in production process that draws being stained with on fixture that draw, avoid repeatedly polluting TDO baking oven, pollute the film in producing, thereby alleviated the damage in packaging film feeding and wrapup procedure, improved the apparent property of film; This device can effectively reduce the de-folder of film phenomenon simultaneously, and reduces back rapidly the temperature of rail section fixture, is convenient to fixture and is producing in being applicable to again pressing from both sides film at temperature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
With reference to Fig. 1, a kind of novel thin film transverse stretching machine, comprises two revolution chain rails 1, described revolution chain rail 1 is provided with circumversion chain, it is active section that described circumversion chain is provided with 2, two relative rail sections of revolution chain rail 1 of fixture, and the rail section in the outside of two revolution chain rails 1 is back rail section;
In described returning in rail section, be provided with dedusting cooling duct 3, described dedusting cooling duct 3 is provided with gas outlet, described dedusting cooling duct 3 is provided with the high pressure valve 4 that is matrix distribution stretching in described dedusting cooling duct 3, distance between adjacent high pressure valve 4 is 1 ~ 2 fixture width, described high pressure valve 4 is perpendicular with described fixture 2, and the distance between described high pressure valve 4 and fixture 2 is 2 ~ 5cm.
The present invention is by returning rail section installation dust-cleaning and refrigerating mechanism, can effectively remove horizontal folder bits dust and the horizontal little molecule producing in production process that draws being stained with on fixture that draw, avoid repeatedly polluting TDO baking oven, pollute the film in producing, thereby alleviated the damage in packaging film feeding and wrapup procedure, improved the apparent property of film; This device can effectively reduce the de-folder of film phenomenon simultaneously, and reduces back rapidly the temperature of rail section fixture, is convenient to fixture and is producing in being applicable to again pressing from both sides film at temperature.
