Description
Technical field:
The invention belongs to processing of high molecular material field of mechanical technique, particularly be a kind of hydraulic-driven rubber dynamic plasticizing extrusion method and equipment.
Background technology:
Rubber Extruder is a kind of basic equipment of rubber industry, in the production process of tire and rubber, play very important effect.Rubber Extruder appears at the earliest 1851 is that Gu Tabo company plunger-type extruder by Britain manufactures submarine cable, abroad the development experience stages such as plunger-type extruder, screw type hot-feed extruder, common cold feed extruder, major-minor screw thread cold feed extruder, cold feeding vented extruder, pin cold-feed extruding machine, complex extruder of Rubber Extruder.Some rubber manufacturing machinery manufacturers domestic from the 1950's of China develop hot-feed extruder in succession, and from 1984, pin cold-feed extruding machine technology is studied, current pin cold feed extruder has become the leading products in extruder market.
Plasticating is an operation of rubber processing, refers to and adopts machinery or chemical method, reduces rubber relative molecular mass and viscosity to improve its plasticity, and obtains suitable mobility, to meet the needs of mixing and shaping further processing.Rubber Extruder is exactly utilize the method for machinery to plasticate to sizing material, the process that Rubber Extruder extrudes sizing material is generally divided into 3 sections: conveying section, fluxing zone, metering section, conveying section is positioned at hopper lower end and is responsible for sizing material to be transported to fluxing zone, fluxing zone is exactly made the molecular chain rupture of rubber by the effect of the mechanical shear stress between screw rod and machine barrel and high-temperature hot thus reduced the viscosity of sizing material and increase the mobility of sizing material, and metering section keeps the quantitative melt conveying sizing material of temperature of sizing material to head.Plastify homogenizing further also to the pressure that sizing material is certain at the head position sizing material of extruder, ensure the excellent of the closely knit quality of rubber.
For traditional extruder, it is plasticated to sizing material by the effect of shearing force between extruder screw and machine barrel, but when sizing material enters cross-head position the Mooney viscosity of sizing material still very large this just cause the difficulty of rubber-moulding to affect production efficiency.And compound viscosity large sizing material in head position is by just needing larger pressure when die extrusion, also likely cause rubber in the accumulation at head position, thus the temperature of the overlong time sizing material that sizing material is stopped at extruder screw position raise the too high quality causing glue to burn phenomena impair rubber.
Summary of the invention:
The object of the invention is to overcome the deficiencies in the prior art, seek design and provide a kind of hydraulic-driven rubber dynamic plasticizing extrusion method and equipment, this extrusion method and equipment effectively can reduce the Mooney viscosity of head position rubber and to provide certain pressure to make sizing material can have better mobility gained rubber more closely knit.
The present invention is different from traditional Rubber Extruder, and this rubber dynamic plasticizing extruder adds a dynamic plasticizing system on the basis of original Rubber Extruder, and its position is positioned at the end of cross-head feed end i.e. screw rod.This dynamic plasticizing system is completed by hydraulic-driven, it has two hydraulic cylinders to lay respectively at the two ends up and down of head, connecting rod hypomere in hydraulic cylinder is with a plasticizing block, realized the viscosity of the sizing material that the dynamic plasticizing of sizing material in extrusion makes macromolecular chain fracture reduce further with regard to enough reverse reciprocating operation by two hydraulic pressure, although because the effect of mechanical force reduces but mechanical force plays again strong activation and makes sizing material contact fully with oxygen when temperature is higher, thus make the lancing of rubber molecule hydroperoxides chance be cleaved into the very little molecule of relative molecular mass; And this extruding is back and forth returned sizing material and is provided certain pressure to make sizing material kneading again and the pressure that provides can contribute to the raising of extruding of sizing material and rubber quality.
A kind of rubber dynamic plasticizing extruder of the present invention, its agent structure comprises: head 1, hydraulic cylinder petroleum pipeline 2, hydraulic cylinder 3, hydraulic cylinder connecting rod 4, plasticizing block 5, fastening bolt 6, machine barrel 7, screw rod 8, drawing-in device 9, bearing 10, reduction box 11, pedestal 12, support 13; Link with fastening bolt 6 between head 1 with machine barrel 7, machine barrel 7 is arranged on drawing-in device 9, tandem type shaft is shaped with to circulating cooling runner in barrel wall, plasticizing block 5 is installed to the lower end of hydraulic cylinder connecting rod 4, screw rod 8 right-hand member is installed bearing 10 and is linked by pin and the gear in reduction box 11, head and machine barrel link with support 13, and support is fixed on pedestal 12, wholely constitute rubber dynamic plasticizing extruder.
Accompanying drawing illustrates:
Fig. 1 is rubber dynamic plasticizing extruder overall schematic
Fig. 2 is rubber dynamic plasticizing extruder partial sectional view
Fig. 3 is rubber dynamic plasticizing extruder head position sectional view
Wherein 1 is head, and 2 is hydraulic cylinder petroleum pipeline, and 3 is hydraulic cylinder, and 4 is hydraulic cylinder connecting rod, and 5 is plasticizing block, and 6 is fastening bolt, and 7 is machine barrel, and 8 is screw rod, and 9 is drawing-in device, and 10 is bearing, and 11 is reduction box, and 12 is pedestal, and 13 is support.
Detailed description of the invention:
Also the present invention is described further in conjunction with specific embodiments to contrast accompanying drawing below.
The present invention is to provide a kind of hydraulic-driven rubber dynamic plasticizing extrusion method and equipment, in the present invention, screw rod 8 is connected with the gear in reduction box 11 by key as shown in Figure 2, the head 1 of extruder is all be connected by fastening bolt with machine barrel, drawing-in device 9 with machine barrel and other junction, and plasticizing block 5 is installed to the lower end of hydraulic cylinder connecting rod.Opening power, the gear driven bolt rotary in reduction box; The logical oil of hydraulic cylinder, the connecting rod of hydraulic cylinder does the reciprocating motion of 2-10 time per second.Sizing material is added from drawing-in device, the conveying section of screw rod starts material feeding and transports sizing material toward fluxing zone, reduction rubber due to fluxing zone pitch starts to be squeezed and sizing material and barrel wall is produced and rubs, by frictional force sizing material sheared and heat thus reach the plastication to sizing material, sizing material enters into metering section by fluxing zone and then keeps the temperature of sizing material and be transported to head position, the plasticizing system at head position starts to carry out work to sizing material, by two hydraulic mechanism reciprocating extrusion, the secondary plasticizing effect of Mooney viscosity realization to sizing material that kneading reduces sizing material is carried out to sizing material, what the reciprocating of hydraulic mechanism returned that the certain pressure of sizing material makes sizing material be more prone to like this is extruded and the more closely knit better quality of the rubber of gained.
Instant invention overcomes the deficiencies in the prior art, devise a kind of hydraulic-driven rubber dynamic plasticizing extrusion method and equipment, the present invention devises dynamic plasticizing system when not changing conventional extruder agent structure at head position, structure simple effects is good, can apply widely in rubber plastic industry.
