Filtering molding face A down progresses into slurries liquid level below, forwards to from wet base transfer station L and inhales slurry station S; And filtering molding face B up exposes the slurries liquid level gradually, exposes the slurries liquid level fully until the filtering molding mould and arrives wet base transfer station L; The B face that exposes liquid level stays wet base in die cavity, water in the wet base is further siphoned away, after reaching the moisture content of regulation, the die cavity dewatering hole is closed towards the control valve of negative pressure device, dewatering hole and described negative pressure device disconnect, and finish wet blank molding, and then wet base shifts the mobile wet base of B face of taking away under the mould 7a, filtering molding mould B face die cavity is in sky and closes state, waits for that enter slurries carries out filtering molding next time.Have one or more die cavities and be in the filtering molding face A that inhales on the slurry station S, the die cavity dewatering hole is opened towards the control valve of negative pressure device, dewatering hole is communicated with described negative pressure device, water in the part slurries is discharged the dewatering hole in the die cavity of filtering molding mould A face under the effect of negative pressure and is taken away, fiber is attracted on the woven wire in the die cavity of filtering molding mould A face and begins to form described wet base, is the wet base of A face.
After filtering molding face A reaches the wet base adsorption time of regulation, filtering molding face B with filtering molding face A around horizontal rotating shaft by with the side of last Rotate 180 degree Rotate 180 degree in the opposite direction, shown in Fig. 4-6,4-7,4-8,4-9: filtering molding face B down progresses into slurries liquid level below, forwards to from wet base transfer station L and inhales slurry station S; And filtering molding face A up exposes the slurries liquid level gradually, exposes the slurries liquid level fully until the filtering molding mould and arrives wet base transfer station L; Filtering molding face B, beginning filtering molding make the wet base (shown in Fig. 4-9 or Fig. 4-1) of B face.Filtering molding face B has one or more die cavities, the die cavity dewatering hole is opened towards the control valve of negative pressure device, dewatering hole is communicated with described negative pressure device, water in the part slurries is discharged the dewatering hole in the die cavity of filtering molding mould B face under the effect of negative pressure and is taken away, fiber is attracted on the woven wire in the die cavity of filtering molding mould B face and begins to form described wet base, is the wet base of B face.And the A face that has exposed liquid level stays wet base in die cavity, water in the wet base is further siphoned away, after reaching the moisture content of regulation, the die cavity dewatering hole is closed towards the control valve of negative pressure device, dewatering hole and described negative pressure device disconnect, and finish wet blank molding, and then wet base shifts the mobile wet base of A face of taking away under the mould 7a, filtering molding mould A face die cavity is in sky and closes state, waits for that enter slurries carries out filtering molding next time.Get back to the B face that slurries liquid level below has also begun filtering molding again, begin to make the wet base of B face again, enter next circulation, so move in circles, filtering molding face A and filtering molding face B alternately make wet base, and wet base transfer device 7 alternately is sent to the wet base of the A face on the wet base transfer station L and the wet base of B face in the hot pressing die of left thermocompression forming device 3 and right thermocompression forming device 4.
Because filtering molding die face B(or A face) form in the process of wet base and the filtering molding mould is turning in the process of turnback at adsorbing fiber, filtering molding face on the filtering molding mould is down or (shown in Fig. 4-1,4-2,4-3,4-4,4-6,4-7, the 4-8) that tilt, so do not have residual slurries phenomenon at the depression position of filtering molding mould, so the wet base wall ratio that forms is more even.The filtering molding mould that exposes liquid level stays wet base in die cavity, the water in the wet base is further siphoned away, reach the moisture content of regulation after, filtering molding finishes, finish wet blank molding, this method filtering molding mould spins upside down around axle, is called convertible " dragging for the slurry method " filtering molding.
" slip casting method " filtering molding and " dragging for the slurry method " filtering molding all are the methods that forming device is made wet base.String or paper pulp are made wet base through filtering molding earlier, again wet base alternately is sent in the hot pressing die of left thermocompression forming device 3 and right thermocompression forming device 4, has accepted the hot pressing die matched moulds of the left thermocompression forming device of wet base or right thermocompression forming device and wet base is carried out the hot-pressing drying typing.Be that example describes with two thermocompression forming device patterns now.Concrete action can be like this, after wet base is in wet base transfer station L and finishes wet blank molding, wet base transfer mould 7a vertically is moved to reach on the filtering molding mould 2c wet base is picked up, wet base is followed wet base and is shifted mould 7a and upwards promote and put in place, follow left hot pressing counterdie 3c (or right hot pressing counterdie 4c) be moved horizontally to wet base shift mould 7a under.Wet base transfer mould 7a moves down wet base is transplanted on left hot pressing counterdie 3c (or right hot pressing counterdie 4c), and wet base shifted mould 7a rising after wet base shifted and finishes; Left side hot pressing counterdie 3c (or right hot pressing counterdie 4c) is being with wet base level to turn back to original position, descending and the left hot pressing counterdie of left side hot pressing patrix 3a 3c matched moulds, or the descending and right hot pressing counterdie of right hot pressing patrix 4a 4c matched moulds carry out the hot-pressing drying typing to wet base, make dried product, goods just to be cut edge.
When wet base in the hot pressing die of left thermocompression forming device 3, after the heat drying typing, move on to the position on left hot pressing patrix 3a die sinking and the absorbent articles.Left side hot pressing counterdie 3c moves to right, and location, a left side connects material and asks 5.1 also to move to right with left hot pressing counterdie.When left hot pressing counterdie 3c move on to wet base shift mould under the time, stop mobile, admittance is shifted mould from wet base and is shifted the wet base of coming, left side location connect material holder 5.1 just in time be positioned at left hot pressing patrix 3a under, goods on the left side hot pressing patrix 3a drop on a left side correspondingly and locate in the holder 5.1 that connects material, after this along with moving to left of left hot pressing counterdie resets, the holder 5.1 that connects material of location, a left side also moves to left and gets back to original position; Equally, move on to the position on right hot pressing patrix 4a die sinking and the absorbent articles, right hot pressing counterdie 4c moves to left, and right location connects material and asks 6.1 also to move to left with right hot pressing counterdie.When right hot pressing counterdie 4c arrive wet base shift mould under the time, stop mobile, admittance is shifted mould from wet base and is shifted the wet base of coming, right location connect material holder 6.1 just in time arrive right hot pressing patrix 4a under, goods on the right hot pressing patrix 4a drop on right the location in the holder 6.1 that connects material correspondingly, after this along with moving to right of right hot pressing counterdie resets, the holder 6.1 that connects material of right location also moves to right and gets back to original position.
