Detailed description of the invention
With the following Examples the invention is further described.
A kind of coating machine for coated thin film of the invention, for coated thin film 8, this coating machine comprises unwinding device, apparatus for coating, drying unit, flattening-out device, shaping equipment, cooling device and wrap-up successively along film 8 moving directions.
Drying unit comprises baking oven 1, and baking oven 1 operated by rotary motion has some joints.
Baking oven 1 rear side is flattening-out device, flattening-out device comprises flattening-out deflector roll 2, flattening-out adjustment roller 3 and heater 5, flattening-out deflector roll 2 and flattening-out are adjusted roller 3 and are be arranged in parallel side by side, flattening-out adjustment roller 3 is specifically arranged at the top of flattening-out deflector roll 2, flattening-out deflector roll 2 is drive roll, it is driven voller that flattening-out is adjusted roller 3, and flattening-out deflector roll 2 and flattening-out are adjusted between roller 3 and be provided with a gap, and film 8 passes from this gap.Heater 5 is for heating flattening-out deflector roll 2, or adjusts roller 3 for flattening-out, also can heat flattening-out deflector roll 2 and flattening-out simultaneously and adjust roller 3.
Preferably, flattening-out deflector roll 2 adopts a deflector roll of the caudal end of final section baking oven 1, and 1, baking oven heats flattening-out deflector roll 2 as heater 5, and flattening-out is adjusted 3, roller and is preferably rubber roll.Utilize baking oven 1 heat own to heat flattening-out deflector roll 2,2 of flattening-out deflector rolls do not need additional heat, can save the energy, but, for some thicker films, only heat with baking oven 1, the heat of flattening-out device perhaps can be not enough, at this moment can heat it by heater 5 being set on flattening-out adjustment roller 3, think that flattening-out device provides enough heats.
Flattening-out device also comprises for regulating flattening-out deflector roll 2 and flattening-out to adjust the control valve 4 of the chinky altitude between roller 3, because flattening-out deflector roll 2 preferably adopts the deflector roll of the tail ends of final section baking oven 1, therefore 4, control valve is for regulating flattening-out to adjust roller 3.
Film 8 is carried out before flattening-out, adjust the chinky altitude between flattening-out deflector roll 2 and flattening-out adjustment roller 3 by control valve 4, make chinky altitude be less than or equal to the thickness of film 8, or directly adjusting flattening-out adjustment roller 3 fits with flattening-out deflector roll 2, in the time that film 8 passes gap, film 8 is heated and is extruded, and film 8, by rapid flattening-out, recovers smooth.
Flattening-out is adjusted the control valve 4 of roller 3 and is installed on baking oven 1 outside, is convenient to regulate at any time flattening-out to adjust roller 3 pressure at two ends, revises in time film 8 flatness, the screw thread of control valve 4 must be fine and closely woven accurately, guarantee that flattening-out is adjusted the stroke that roller 3 moves up and down accurate.
Because flattening-out adjustment roller 3 is set in parallel in flattening-out deflector roll 2 tops side by side, in the time that flattening-out deflector roll 2 adopts baking oven 1 to heat, baking oven 1 internal temperature is up to 150 DEG C, is preferably high temperature resistant 200 DEG C of above colloid flattening-outes adjustment rollers therefore flattening-out is adjusted roller 3.
Film 8 is after flattening-out, and before cooling, deformation occurs film 8 very easily again, therefore shaping equipment is set at flattening-out device rear.Shaping equipment comprises two setting rolls 6 that are set up in parallel, and is respectively setting roll and lower setting roll, and film 8 is through described upper setting roll and lower setting roll.Upper setting roll and lower setting roll are all preferably minute surface setting roll, and the diameter of section of setting roll 6 is preferably greater than or equal to 0.5m.In the time that film 8 passes through shaping equipment, large diameter setting roll 6 can carry out pre-cooled to film 8.
After sizing, film 8 enters cooling device immediately, because the extrusion film 8 that is heated is without cooling and shaping, now, there is deformation in film 8 very easily again, therefore entering before cooling device, the deflector roll that drives film 8 to advance must change to minute surface guide wheel by aluminum deflector roll, between flattening-out device and cooling device, be minute surface deflector roll for promoting the deflector roll that film 8 advances, to reduce frictional force and to keep flatness, the bearing of minute surface deflector roll needs perfect lubrication.The water temperature of cooling device must remain on 18 DEG C, after apparatus for supercooling, can enter wrap-up.
For saving cost, shaping equipment and cooling device can be arranged to one, cooling in sizing, can save a covering device.
Finally should be noted that; above embodiment is only in order to illustrate the technical scheme of the invention; but not restriction to the invention protection domain; although the invention has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical scheme of the invention, and not depart from essence and the scope of the invention technical scheme.
