Wherein, barrier film is connected to chemical material dip-coating district by unreeling parts, and through vertical mode by baking zone, secondary baking district, finally close at the rolling parts.
Further, one time baking zone is relative shallow trench isolation with the secondary baking district, and temperature is independent adjustable.But two baking zones respectively include two baking boxes at barrier film left and right sides vertical distribution, and two baking box blowing mouths carry out heated-air drying over against the barrier film two sides.
Further, described baking box blowing mouth is distributed as baking box and distributes over against whole diaphragm area.
Further, chemical material dip-coating parts comprise that being installed on soaking of a baking zone bottom expects the pond, soak in the material pond roller is installed, and this roller is positioned at the position of center line of two baking box spacings of a baking zone.
Described barrier film coating machine also includes outside hot air source.
Described barrier film coating machine also includes electrostatic treatment devices.
By the barrier film coating machine that as above part of appliance and structure are made, its beneficial effect comprises: barrier film coating chemical material adopts vertical to rise, descend, can be so that the liquid chemical material evenly distributes on the barrier film two sides; Adopt two bake region simultaneously, and in two bake region, each adopts at the baking box of setting up about barrier film, makes barrier film two sides uniform drying.
Description of drawings

Fig. 2 is the side view of the utility model barrier film coating machine
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The specific embodiment
The utility model barrier film coating machine as shown in Figure 1, its structure includes as follows:
Unreeling structure: as shown in Figure 1, form by unwinding rack 1, bearing 1 ', inflatable axle 2.Web-like barrier film 3 is installed on the inflatable axle 2, and inflatable axle 2 inflation back web-like barrier films 3 will be subjected to expansive force fixedly on the inflatable axle 2.Inflatable axle 2 two end axles are placed on the two bearings 1 ', and can roll between bearing 1 ' in inflatable axle 2 two ends when barrier film is subjected to the pulling of back mechanism.
Dip-coating mechanism: by soak material pond 5, roller 6, magnetic stirring apparatus 7 is formed.Distribution baking box 8 spacing position of center line about wherein the utility model roller 6 is preferably and is positioned at.During work, the solvent that 7 pairs of magnetic stirring apparatus soak material pond 5 stirs, and when barrier film passed roller 6, the barrier film two sides will be coated with chemical material.
Baking components: when barrier film arrives a baking zone by soaking after coming out in material pond 5, baking zone includes two baking boxes 8 at barrier film left and right sides vertical distribution, two baking boxes 8 are toward middle spacer film blowing hot-air, and the hot blast of baking box 8 is provided by the heating box of machine outside.The secondary baking parts: enter the secondary baking district after barrier film is through a baking zone, as shown in Figure 1, the secondary baking district also is made up of two baking boxes 11 at barrier film left and right sides vertical distribution.
Actuating unit: power section is made up of the driving wheel 13 that is positioned at the secondary baking lower box part, pinch roller 14, cylinder 15, motor 2 ' etc.Power section produces the pulling force of front operation.Be specially: when machine begins barrier film via unreeling structure, soak material pond 5, baking zone and pass again between driving wheel 13 and the pinch roller 14, pinch roller 14 promotes to compress barrier film by cylinder 15, motor 2 ' drives driving wheel 13 and produces pulling force and at the uniform velocity spur barrier film.
Rolling-up mechanism: rolling part is by rolling frame 18, inflatable axle 17, the device 19 of rectifying a deviation, the device of rectifying a deviation probe 16, torque motor 2 " etc. form.After barrier film is through front multistage operation, just it is carried out rolling by rolling-up mechanism.Be specially: barrier film is fixed on the rolling inflatable axle 17 fixing, by torque motor 2 " and synchronizing wheel be with mechanism to drive inflatable axle 17 synchronously to rotate barrier film is carried out rolling; carry out left and right sides sideslip by the 16 pairs of barrier films of device probe of rectifying a deviation in the wrapup procedure and detect, and the 19 pairs of barrier films of Deviation rectifier below the control rolling frame are rectified a deviation about carrying out.
The overall work step that the utility model uses is:
Web-like barrier film 3 without dip-coating is contained on the inflatable axle 2 of unwinding rack, produces pulling force pulling barrier film through soaking material pond 5 dip-coatings by power wheel 13, carries out rolling through entering rolling-up mechanism after two bake region again.Be specially: when device start, driving wheel 13 drives pinch roller 14 by cylinder 15 and compresses barrier film, and driving wheel will spur barrier film when rotating, the pulling adjustable-speed.Barrier film enters through accessory drive wheel 4 and soaks material pond 5.Soak the inside, material pond solvent is housed, and as shown in Figure 1 roller 6 is installed, barrier film up arrives baking box 8 again after soaking material pond 5 process solvent-saturated, baking box 8 by respectively by about two vertical install and form toward the casings of middle spacer film passage blowing hot-airs, again through accessory drive wheel 9, accessory drive wheel 10 arrives baking box 11 to barrier film after tentatively toasting through baking box 8.Baking box 11 equally also respectively by about two vertical install and form toward the casings of middle blowing hot-airs, the temperature of two baking boxs is independently adjustable.Through after the baking of baking box 11, barrier film parches fully.Barrier film arrives driving wheel 13 through accessory drive wheel 12 again, carries out rolling by rolling-up mechanism 18 at last.Rolling-up mechanism is mainly by torque motor 2 " and synchronizing wheel, the band transmission formed of band, inflatable axle 17 synchronously form.The rolling frame is equipped with the device probe 16 of rectifying a deviation as shown in Figure 1, and Deviation rectifier 19, can carry out automatic deviation correction when about membrane unwinding deviation being arranged.When driving wheel 13 runnings, simultaneously accessory drive wheel 4, accessory drive wheel 9, accessory drive wheel 10, accessory drive wheel 12 are at motor 2 ', motor 2 ", drive down can the linear velocity running identical with driving wheel 13; thereby eradicate a mental barrier and the frictional force of each accessory drive between taking turns, avoid membrane surface to be scratched by drive.
