Description

The synthesis stone thin plate single lead screw ex truding briquetting machine

One, technical field

The utility model belongs to a kind of building material machinery, particularly a kind of synthesis stone thin plate single lead screw ex truding briquetting machine.

Two, background technology

Along with the building and the development of adnornment industry, the application of the microlite that synthetic stone is especially made with trickle stone grain and unsaturated polyester resin is increasingly extensive.The moulding process of synthetic stone mainly contains at present and adopts the vacuum vibration formation machine to carry out the moulding of three-dimensional waste material earlier, or adopts thin plate shaping apparatus block-by-block concora crush and one-time formed two kinds of methods.All there is certain deficiency in two kinds of moulding process, and its waste material moulding is must carry out sawing through saw after it solidifies, and its saw kerf will consume former, the auxiliary material and the instrument consumption of 25%～40% synthetic stone; The moulding of thin plate piecemeal be it with addition of amount of resin more relatively, and equipment manufacturing cost is also higher.The existing former with modulus of continuity plastics has screw extruder etc., Chinese patent for example, notification number is CN2584397Y, name is called " screw extrusion device of double-screw extrusion machine; " the material body that extruding is presented soft shape has certain advantage, but when being squeezed into thin sheet material with its synthetic building stones that trickle stone grain is accounted for main body, can only be with addition of the amount of resin more than 15% and set up milling roller and carry out sheet forming.

Three, summary of the invention

The purpose of this utility model is intended to the interrupted and whole molding mode of the synthetic stone of crystallite is changed into continuously and the molding mode of burst, parallel and the pushing step by step with the many spirals of its device specific, the material direction of flow is regulated and the pressure ring that prolongs of oscillatory type saves the sheet forming that carries out its continuation, it is reduced production costs in consuming significantly reducing former, supplementary product consumption and processing, and improve the quality and the artistry of its product.

The technical scheme that its technical problem that solves the utility model adopts is: the synthesis stone thin plate single lead screw ex truding briquetting machine, comprise motor, decelerator (1), porous neck bush (3), cylindrical shell (4), extrude and regulate cylinder (5), prolong depressor (6), vibrator (7), transport tape (8) and many spirals combination roller (2), it is characterized in that, described many spiral combination rollers are arranged in parallel by two to four propellers and form, to interlock the ratio of its fin helical pitch (distance between the helical wing plate) be 1: 1.2～2 or 1: 1.2～1.6: 1.8～2.4 screw-casing (9) in segmentation on the mandrel of its propellers, adopt the less number joint screw-casing of fin helical pitch from the exit of extruded stock, the bigger screw-casing of its helical pitch of connecting successively, compress with double nut after it all is series at mandrel, then be threaded onto in porous neck bush (3) and the cylindrical shell (4).These propellers also can adopt the technology of monoblock cast propellers, and it is made into the propellers that the fin helical pitch strengthens step by step.Extrusion place at the cylindrical shell of many propellers installs oval-shaped ring flange, and connects and extrude the adjusting cylinder.The described cylinder body of regulating cylinder (5) of extruding adopts corrosion resistant plate to make plane broadening and cylindrical shell that the diminishing total section of thickness reduces gradually gradually, and the inlet in from two to four holes seamlessly transits to the outlet of slit shape.The equipped in the middle transversely arranged two ends that are divided into two to ten rhombuses of two groups are the control valve of rotating shaft, every group of control valve controlled with a handwheel and gear, in the rotation of its handwheel, make the synchronous rotation in groups of control valve of its rhombus, change the flow direction that its material body is extruded with the catch rotation formula.The described troughing plate (10) that prolongs depressor (6) bottom is installed in the exit of extruding cylinder with bolt, it is divided into forward and backward two sections upper flat plate, the feed side of its leading portion is connected in rotating shaft and extrudes the cylinder exit, altogether the exit side of leading portion (11) can be connected as one with rotating shaft and horizontally disposed back segment (12) feed side, or the upper flat plate of leading portion, back segment is fixedly connected with rotating shaft at its feed side separately, but all pull-ups and make closed action of two rear side.This prolong the troughing plate of depressor bottom following heavy 30 °～60 ° of modes arrange and become the trough plate of downslide that its lower end is mutually close with the flat board on the transport tape.But to 20～60 the round roller bars of arranging, also this can be justified the space that the bending of roller bar enter back segment upper board and retainer flat board in its centre following current of prolonging the upper and lower part steel plate sealing that depressor glides.

Operation principle of the present utility model is: adopt a plurality of propellers (2), can utilize its corresponding lining to lead to and the synchronous propelling of a plurality of spirals, make it be easy to evenly advance and to the thin plate transition; The way of utilizing the helical pitch segmentation of helical wing plate to reduce can make helical wing plate progressively increase axial advance component, makes the axial advance component of its charging and extruding and discharging harmonious; Adopt the bat pressure and vibrate the depressor that prolongs that combines, can utilize vibrator to carry out reciprocal bat pressure and vibration processes, finish the operation that it gets rid of bubble and further compacting; That adopts that its porous inlet becomes the slit mouth extrudes cylinder (5), and is provided with in the middle with rotating manner and rotates the rhombus control valve, can be beneficial to and extrude the uniform thin plate of density in its flow direction that is divided into two groups be regulated; Be positioned at the transport tape of forward arranging (8) that prolongs depressor and main frame downside, can its with electric or mechanical speed governing in, the flat board of laying on its lamellar material body extruded and the transport tape is synchronously moved, finish the subsequent handling of extrusion modling with continuous fit system.
