Description
Technical field
The present invention relates to industrial extruders field, more particularly to a kind of active net belt net-changing device.
Background technology
Extruder is that plastic heating and shearing are compressed to molten condition, by the machine of its injection material chamber.Plastics are in material chamber
Middle heating, molten state is ultimately become from glassy state via elastomeric state, simultaneously injection material chamber is transported by screw rod.It is miscellaneous due to having in plastics
Matter, thus the plastics of molten state before injection material chamber, it is necessary to use the screen pack removal of impurity, after screen pack uses a period of time,
Because impurity is deposited, it is necessary to draping.Traditional extruder screen is controlled with the heater that draping is exported by water-stop section
The replacing of screen belt processed, it is unstable to walk net length during draping, easily skew, leakage etc., reduces the operating efficiency of draping.
The content of the invention
For the above situation, to overcome the defect of prior art, the purpose of the present invention is just to provide a kind of active net belt
Net-changing device, can effectively solve the problems, such as extruder draping hour offset and leakage in continuous flow procedure, and make up elastic drive
The power problem on the weak side of dynamic device.
Its technical scheme solved is, a kind of active network band net-changing device is included by the first cooling chamber, the first heating chamber and the
The die cavity that two cooling chambers are formed, the interior material chamber, die cavity or so that is provided with of the first heating chamber is through there is chamber groove, and chamber groove is vertical with material chamber, chamber
Activity is placed with screen belt in groove, and cavity is provided with the second cooling chamber, and cavity communicates with material chamber, the second cooling chamber right hand external
Provided with fluid pressure drive device, fluid pressure drive device is connected with screen belt.
Clever structure of the present invention, manufacturing process is simple, easy to use, and automatic draping, sealing are realized without manual operation
Can be good.
Brief description of the drawings
Fig. 1 is structural representation front sectional view of the present invention.
Fig. 2 is structural representation top view of the present invention.
Embodiment
It is described in further details below in conjunction with 1,2 pair of embodiment of the invention of accompanying drawing.
From Fig. 1,2, a kind of active net belt net-changing device includes cold by the first cooling chamber 3, the first heating chamber 4 and second
But the die cavity 1 that room 5 is formed, 4 interior be provided with of the first heating chamber expect chamber 9, and die cavity 1 or so is through there is chamber groove 2, and chamber groove 2 is with expecting that chamber 9 hangs down
Directly, activity is placed with screen belt 10 in chamber groove 2, and cavity is provided with the second cooling chamber 5, and cavity communicates with material chamber 9, the second cooling
The right hand external of room 5 is provided with fluid pressure drive device 13, and fluid pressure drive device 13 is connected with screen belt 10.
The first described cooling chamber 3 among the first heating chamber 4, the first heating chamber 4 is among the second cooling chamber 5 with being equipped with
Heat insulation slot 14.
Water channel 7 is provided with described the first cooling chamber 3, the second cooling chamber 5.
Heating tube 8 is provided with the first described heating chamber 4.
The described right hand external of the second cooling chamber 5 is provided with Sealing shield ring 6, and Sealing shield ring 6 includes being fixed on the right-hand member of die cavity 1
Fixed back-up ring and the movable back-up ring for being movably connected in the right-hand member of die cavity 1, movable back-up ring control through hydraulic cylinder.
The described rear side of 9 filtering net band of material chamber 10 is provided with porous plate 11.
In the use of the present invention,
Expect the molten state plastics in chamber 9, major part after being filtered by screen belt 10 by the injection material chamber of porous plate 11.A part is entered
Enter the cavity of the second cooling chamber 5, in the presence of water channel 7, rapid cooled and solidified forms a material plug 12, seals, prevents
Only plastic leakage.A part of plastics enter chamber groove 2, and in the presence of water channel 7, quickly solidify and be attached to stainless steel filtering net
On, seal, prevent plastic leakage.Screen belt 10 has rigidity well using the stainless (steel) wire band of establishment synthesis
And tensile resistance, it can effectively filter the impurity in molten state plastics.
When depositing contaminants are excessive before expecting the screen belt 10 in chamber 9, the flowing of molten state plastics is not smooth, before screen belt 10
Pressure rise.Electrical control gear senses change in pressure, water channel 7 is cut off, so that material plug 12 is changed into partly melting state and may move, together
When opening activity back-up ring.Now electrical control gear can start drive device 13, drive screen belt 10 to move, drive device 13
It can ensure that filter screen band 10 operates steadily according to stressing conditions automatic driving-force adding.
After screen belt 10 moves a certain distance, pressure declines before screen belt 10, and electrical control gear stops driving
Device 13 and closing activity back-up ring, while water channel 7 is opened, material plug 12 is stopped mobile and solidify again, wherein heating design is
Independent floating heating design, so that the formation of material plug 12 has more perfect condition.Auxiliary drive 13 is pressure activation bullet
Property drive device, can be according to working condition automatic driving-force adding.
The present invention improves guipure and walks net control mechanism, makes to walk network control system more stable.Optimization design floating heating system,
Floating heating can be carried out according to temperature requirements, material plug is had more perfect condition.The exchange interlocking work(of draping action control can be achieved
Can, so as to realize that the function of cooling water, heating and process auxiliary drive replaces, even if guipure, which is walked, netted the leakage that mostly occurs, sealing baffle
Also the generation of seal section prevent leakage can be blocked rapidly, it is ensured that guipure walks the automaticity of net and the reliability of sealing.With connecting automatically
Continuous draping is without manual operation, draping process stabilization, and stream is without fluctuation, the advantages that product quality is stable.Be applicable to PP, PE,
The wire drawing of the plastic melts such as ABS, PS, it is granulated, film, sheet material, sheet material, the production of fiber etc..
