The extruding machine comprises an upper threaded rod, a vacuum bin, a lower threaded rod, a duckbill nozzle and an extruding forming die. The extruding machine further comprises a flow stabilizing pipeline, one end of the flow stabilizing pipeline is connected with an outlet of the lower threaded rod, and the other end of the flow stabilizing pipeline is connected with an inlet of the duckbill nozzle. According to the extruding machine for the fiber cement boards, the flow stabilizing section is additionally arranged between the lower threaded rod and the duckbill nozzle, the flow stabilizing pipeline has a long pipeline space used for containing many materials, the material flow fluctuation is buffered, the finished product rate of sheets is increased, and waste of raw materials is reduced.
Description
Technical field
The utility model relates to a kind of extrusion molding apparatus, particularly, relates to a kind of extruder of fiber cement board.
Background technology
In the forming process of fibre cement sheet material, various raw material, according to formula requirement, after accurate weighing, add mixer fully to stir, and then enter kneader, muller is made homogeneous plasticity material piece, puts into extruder.As shown in Figure 1, extruder is divided into four parts from top to bottom by structure: upper screw rod 1, vacuum chamber 2, lower screw rod 3, duckbilled 4 and mould 5.Material piece first enters upper screw rod 1 by charging aperture 11, then sends into vacuum chamber 2, the vacuum of vacuum chamber 2 generally-below 0.08MPa, can fully discharge like this air in material piece.Then expect that piece passes through lower screw rod 3 and releases forward, through duckbilled 4 and the mould 5 extrusion molding mould shapes of extruder front end, form the sheet material of different cross section shape.
But at present extruding in the process of fibre cement sheet material, extrude duckbilled less with the distance between extrusion screw rod, screw rod is in use due to wearing and tearing, and extruding flow can change, make mould 5 in plate forming, cause defective sheet material, cause waste of raw materials phenomenon.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of extruder of fiber cement board, and can prevent from extruding flow can change, and makes mould in plate forming, cause defective sheet material, reduces waste of raw materials.
The utility model provides a kind of extruder of fiber cement board, comprise screw rod, vacuum storehouse, lower screw rod, duckbilled and extrusion molding mould, also comprise current stabilization pipeline, one end of described current stabilization pipeline is connected with the outlet of lower screw rod, and the other end is connected with the entrance of described duckbilled.
Preferably, the inwall of described current stabilization pipeline is provided with liner plate.
Preferably, described liner plate is provided with along the groove of described current stabilization pipeline axial direction.
Described current stabilization pipeline is spliced by polylith circular arc wall body.
Preferably, be provided with one or more water cooling chambers in the wall body of described current stabilization pipeline, described water cooling chamber is provided with water inlet and delivery port.
Preferably, while being provided with multiple described water cooling chamber in the wall body of described current stabilization pipeline, multiple described water cooling chambers are connected in series successively by pipeline.
Compared with prior art, the utility model embodiment beneficial effect is as follows:
1, the extruder of the fiber cement board of the utility model embodiment, by increased steady flow segment between lower screw rod and duckbilled, barretter road has one section of longer pipeline space, this segment pipe space holds more material, cushion the fluctuation of mass flow, improve the yield rate of sheet material, reduce waste of raw materials.
2, the extruder of the fiber cement board of the utility model embodiment, owing to being provided with water cooling chamber, can be by the heat of taking away material and producing in extrusion process, thereby avoid the problem that causes the material in duckbilled and mould to solidify because temperature of charge is too high, improve the yield rate of sheet material, reduce waste of raw materials.

Fig. 2 is the schematic diagram of the extruder of the fiber cement board in the utility model embodiment;
Fig. 3 is the generalized section of the current stabilization pipeline in the utility model embodiment;
The upper screw rod of Reference numeral: 1-, 11-charging aperture, 2-vacuum chamber, screw rod under 3-, 4-duckbilled, 5-mould, 6-current stabilization pipeline, 61-liner plate, 62-water cooling chamber, 63-water inlet, 64-delivery port,
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, hereinafter in connection with accompanying drawing, embodiment of the present utility model is elaborated.It should be noted that, in the situation that not conflicting, the feature in the present embodiment and embodiment can be combined mutually.
The extruder of the fiber cement board of the utility model embodiment is to realize like this, as shown in Figure 2, comprise screw rod 1, vacuum storehouse 2, lower screw rod 3, duckbilled 4 and extrusion molding mould 5, also comprise current stabilization pipeline 6, one end of described current stabilization pipeline 6 is connected with the outlet of lower screw rod 3, the other end is connected with the entrance of described duckbilled 4, descend like this screw rod not directly to be connected with duckbilled, lower screw rod material is out introduced into current stabilization pipeline, because barretter road has one section of longer pipeline space, this segment pipe space holds more material, cushion the fluctuation of mass flow, improve the yield rate of sheet material.
As shown in Figure 3, the inwall of described current stabilization pipeline 6 is provided with liner plate 61, and liner plate 61 can adopt wear-resisting high chromium cast copper, can improve like this wearability of current stabilization pipeline 6.Described liner plate 61 is provided with along the groove of current stabilization pipeline 6 axial directions, can play like this effect of current stabilization.Current stabilization pipeline 6 is spliced by polylith circular arc wall body.
In the wall body of current stabilization pipeline 6, being provided with can a water cooling chamber 62, water cooling chamber is provided with water inlet 63 and delivery port 64, water cooling chamber 62 can connect a water circulation cooling device like this, like this can be by the heat of taking away material and producing in extrusion process, thereby avoid the problem that causes the material in duckbilled 4 and mould 5 to solidify because temperature of charge is too high, improve the yield rate of sheet material, reduce waste of raw materials.
As shown in Figure 3, in another embodiment, because current stabilization pipeline 6 can be spliced by multiple circular arc wall bodies, at this moment can be provided with a water cooling chamber 62 in each circular arc wall body time, in the wall body of current stabilization pipeline 6, be provided with so multiple water cooling chambers 62.Cooling in order conveniently to carry out water circulation, multiple water cooling chambers 62 can be connected in series successively by pipeline, be that the outlet conduit of water circulation cooling device and the water inlet 63 of a water cooling chamber are connected, the delivery port 64 of this water cooling chamber is connected with the water inlet 63 of next water cooling chamber, the delivery port 63 of next water cooling chamber connects a water cooling chamber 6 again, until the delivery port 64 of last water cooling chamber is connected with the inlet channel of water circulation cooling device.
Although the disclosed embodiment of the utility model as above, the embodiment that described content just adopts for the ease of understanding the utility model, not in order to limit the utility model.Technical staff under any the utility model in technical field; do not departing under the prerequisite of the disclosed spirit and scope of the utility model; can do any amendment and variation what implement in form and in details; but scope of patent protection of the present utility model, still must be as the criterion with the scope that appending claims was defined.
