Abstract
The invention discloses a production process of an anti-seepage plate. A sheet is extruded by a screw, extruded and formed by a rotating die, leveled by a leveling roller and then is cut and rolled; and then a bonding agent is coated on the sheet which is bonded with non-woven fabric. A device for realizing the production process comprises a screw extruder, rotatable rollers on which a concave die and a terrace die are respectively fixed, a leveling roller and a cutting, winding and controlling device, wherein the sheet extruded by the screw extruder and the rotatable rollers are positioned at the same height; the rotatable rollers and the leveling roller are vertically arrayed; the rotatable rollers are provided with an upper roller and a lower roller; the concave die and the terrace die are respectively fixedly connected to the surfaces of an upper roller body and a lower roller body and provided with small holes communicated with the insides of the rotatable roller bodies; and negative pressure air is introduced to the rotatable roller bodies; and a cooling liquid is introduced to the rotatable rollers. The invention can realize the extrusion and the forming of the sheet by the rotating die and continuous production; the sheet is leveled by the leveling roller, so that the planeness can be improved; and the concave die and the terrace die can rotate along with the upper roller body and the lower roller body to realize the rotary forming, so that the production efficiency can be improved and 30 percent of labor consumption can be reduced.
Description
One, technical field
The present invention relates to barrier sheet, particularly relate to barrier sheet manufacturing process and device.
Two, background technology
The draining barrier sheet is made up of adhesive-bonded fabric permeatable filter layer and concave-convex substrate, adhesive-bonded fabric and waterproof superimposed substrate, the adhesive-bonded fabric permeable formation is integral by the convex surface and the waterproof substrate bonding of waterproof substrate, form drainage channel between the convex-concave surface of waterproof substrate and the adhesive-bonded fabric permeatable filter layer, the waterproof substrate is a plastics book plate, the waterproof substrate is by heat ductile forming, its manufacturing process is: plastics material grain is made sheet material by screw extruder, winding shaping, sheet material heats, is pressed into convex-concave surface by flat plate mold, reel through cooling, cutting edge, compound with adhesive-bonded fabric.
Its shortcoming is all will heat, cool off when making sheet material and sheet material compacting, and heating energy source consumption is big repeatedly, the manufacturing cost height; Can not produce continuously, recruitment is many.
At present, apparatus for manufacturing substrate is by dull and stereotyped hydraulic press, upper and lower heating platen, mould and draw-gear are formed, upper hot pressboard has electric heater unit that plastic sheet is heated, lower hot pressing board is connected with the air of certain vacuum degree by mould, mould is produced sheet material depress suction, thereby produce convex-concave surface.
Its shortcoming is that every batch of dull and stereotyped mold pressing can only a mould, can not produce continuously, and production efficiency is low.
Three, summary of the invention
The objective of the invention is provides a kind of barrier sheet continuous production processes technology and device in order to overcome above-mentioned weak point.
For solving the problems of the technologies described above, barrier sheet manufacturing process of the present invention adopts: the screw rod extrusion sheet, and through the rotary die extrusion molding, by smoothing drum rolling sheet material, cutting edge rolls, and external coating adhesive and nonwoven are bonding.
Compared with prior art, the present invention by to sheet material through the rotary die extrusion molding, can when the process of extrusion sheet, realize extrusion molding, realization continuity production; By smoothing drum rolling sheet material, improved the product flatness.
Barrier sheet manufacturing installation of the present invention, comprise screw extruder, be fixed with rotatable drum, smoothing cylinder, cutting edge, rolling and the control device of concave, convex mould respectively, the sheet material that screw extruder is extruded exports and has the rotatable drum gap of concave, convex mould at sustained height, swing roller is arranged above and below with the smoothing cylinder, respectively by driven by servomotor; Swing roller has up-down roller, and the concave, convex mould is fixedly connected respectively on upper and lower barrel surface, and the concave, convex die surface has in aperture and the swing roller body and communicates, and is connected with negative pressure air in the swing roller body; Swing roller is supported by axle, and the axle center is connected with cooling fluid.
The invention has the beneficial effects as follows that the concave, convex mould is fixedly connected respectively on upper and lower barrel surface, can follow upper and lower cylinder rotation, realize rotary forming, produce continuously, enhance productivity, reduce by 30% recruitment.

Five, the specific embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated.
Among Fig. 1, barrier sheet manufacturing process of the present invention adopts: screw extruder 1 extrusion plastic sheet material 2 is squeezed into concave, convex shape through rotatable mould, by smoothing cylinder 8 smoothing sheet materials 2, carry out cutting edge according to width dimensions, roll, external coating adhesive and nonwoven are bonding, make finished product.
2 outlets of sheet material that screw extruder 1 is extruded and the rotatable drum that has recessed 5, protruding 6 moulds are at sustained height, swing roller has last 3 times 4 cylinders, recessed 5, protruding 6 moulds are fixedly connected respectively on last 3,4 barrel surfaces down, recessed 5, protruding 6 die surfaces have in aperture and the swing roller body and communicate, and are connected with negative pressure air in the swing roller body; By axle 7 supportings, axle 7 centers are connected with cooling fluid respectively for rotation and smoothing cylinder 8, and swing roller 3,4 and smoothing cylinder 8 are arranged above and below, respectively by driven by servomotor.
