Application examples
Referring to Fig. 2,
Get the device of embodiment 1 gained, be installed in the corresponding site of existing blown film unit, filter plate (91) and filter screen (92) are set in head (1), the barrel (94) that will have screw rod (93) is fixedly mounted on the head (1).
The motor of driven rotary die head is fixedly mounted on the ground, be connected with rotating shaft (26) by gear.
To descend the blast pipe (63) of vane fixedly to make it motionless with iron wire, and put rubber tube at the air intake of blast pipe (63), the other end of rubber tube is enclosed within the air outlet of the bellows that link to each other with cooling air blower.
Above-mentioned steps then obtains having the blown film unit of spinfunction.
When the blown film unit uses first, energising makes the electrothermal wire heating who is coated on barrel (94) outer end, on gas tube (34), put the other end and be connected in rubber tube on the air pump, start air blast, start the motor that drives screw rod again, this motor drives screw rod by reductor and rotates, polyethylene from high pressure process pellet input is connected in the hopper on the barrel, pellet under the promotion of screw rod (93) to head motion, and in barrel, be heated fusing, material is pushed in head (1) inner chamber after filter screen (92) and filter plate (91) enter the center-aisle of linker hypomere (211) by screw rod (93), and enter the inner chamber runner of die head and be extruded from die orifice through the center-aisle of linker epimere (212), become film through the air cooled and solidified that air blast roused, film manually is drawn out to the traction rolling-up mechanism makes it to be tensioned.Starting air pump expands until the film cylinder that becomes required size film, and film is drawn in by the collapser of traction rolling-up mechanism, clamp through pinch upper roll, and cut edge through the cutter of knife rest and to become two-layer single thin film, turn to pinch under roll by the passageway cylinder again, be divided into two width of cloth, respectively by coiling rolling and lower mandrel member rolling.
At this moment end air-pump inflating, the rubber tube that will be enclosed within on the gas tube (34) takes off, and with the valve closing on the gas tube (34), accelerates hauling speed till make film thickness satisfy required size.Start the motor of driven rotary die head, the direction of rotation of control motor changed once in per 5 minutes, making the rotating speed of die head (3) through reducing gear is to rotate a circle in per 2～3 minutes, when die head (3) rotates, vane in the drive (4) reaches down, and vane (5) together rotates, blast pipe (63) is so motionless because of there being iron wire to fix, and fixed head (62) and sealing plate (61) are also motionless, but between the lower surface of the upper surface at the following invagination edge (51) of vane (5) and sealing plate (61) relative frictional rotation is arranged.Because the rotation of die head (3), when making die orifice extrusion film, discharging is even, be 0.6～1.8 ultra-thin miniature thin-film so can make thickness, and thickness is even, can not produce sudden and violent muscle.When die head (3) rotates, relatively rotate between ring flange (211a) upper surface of ring flange (212a) lower surface of linker epimere (212) and linker hypomere (211), because of between contacted two end faces very little space being arranged, so the molten state material is full of these gaps, coefficient of friction between the ring flange is reduced greatly, make this device longer service life.
When the blown film unit reuses, then earlier fuselage, head and die head are heated to 150 ℃～200 ℃ material meltings that make wherein condensation, press the operation of aforesaid operations step again and get final product.
