Detailed description of the invention
Embodiment: as it can be seen, a kind of fluorubber extruder, it includes that reduction box 7 is connected with reduction box 7
The head 1 of screw rod 4, the machine barrel being sleeved on outside screw rod 4 and Screw Extrusion end；The draw ratio of described screw rod 4
For 12:1, with the screw slenderness ratio of conventional rubber extruder at more than 8:1, maximum draw ratio 16:1 phase
Ratio, had both met the big L/D ratio required for cold feed rubber extrusion, had the most fully taken into account fluorubber heat big, screw rod
Unsuitable too long of feature；Hard for fluorubber material, the concrete condition that rigidity is big, the feeding end of screw rod 4 is 4
Head thread form, compared with conventional rubber extruder employing double thread form, the spiral shells of four arrangements that are mutually staggered
Rib is prone to smash sizing material, enhances the material feeding ability of screw rod, it is achieved quickly feed sizing material, reduces sizing material simultaneously and exists
The time of staying in machine barrel；The screw thread of screw rod 4 such as is at the deep Unequal distance, adds with the screw rod mechanism of conventional rubber extruder
The relatively simple form that equidistantly deepens of work is compared, and processes relative complex, but screw strength equilibrium, screw rod
Good to the self-cleaning of sizing material, substantially can empty extruded sizing material, in extrusion fluorubber glue is greatly reduced
The heat of material；Use requirement according to fluorubber goods, fluorubber goods purity wants height, for ensureing serviceability,
Head 1 porch arranges filter offset plate 2 and filter screen 3, according to product process requirement, filter screen 3 use 80 mesh,
The stainless steel cloth of the different meshes such as 100 mesh, the mesh number of filter screen is the biggest, its Kong Yue little, can stop sizing material
In small foreign particle, do not make its foreign particle enter goods, can ensure that the material of extruded product is pure, filter offset plate 2
After filter screen 3, filter offset plate 2 is uniformly arranged some filter openings, sustainable stainless steel filtering net 3, handle simultaneously
Sizing material is rotationally advancing motion in machine barrel, becomes straight ahead by the straight hole of filter offset plate 2 and moves, it is easy to protects
Hold the linear of extruded product, the setting of filter offset plate 2, produce back pressure and act on screw rod 4, improve screw rod 4
Plasticating capacity.The screw rod 4 of extruder and machine barrel all use the alloy steel material of wear-resisting high rigidity, are extruding
Cheng Zhong, it is necessary to machine is heated or cooled, to reach suitable extrusion temperature.Conventional rubber extruder machine
Body endoporus assembling steel alloy machine barrel, fuselage is then manufactured into sandwich, cools down with water flowing.Cooling water under
Side enters fuselage interlayer, flows out from top.This type of cooling, cooling water is practically in laminar condition, one layer
Layer water flows out, and the heat taken away is the most limited, and cooling effect is the best.There is small assembling in fuselage and machine barrel simultaneously
Gap, air therein also affects thermal conduction effect.Due to fluorubber extrusion temperature narrow range, and process warm
Spending much lower compared with the extrusion temperature of ordinary rubber, temperature controls to be that fluorubber realizes the good pass extruded accurately
Key, to this end, barrel design becomes the extruding zone machine barrel 8 one-piece auger water channel by alloy steel material and feeding section machine barrel
5 hole drilling type cooling water channel compositions, substantially increase the cooling effect of machine, and one end of extruding zone machine barrel 8 is arranged
Water inlet 9, the other end arranges delivery port 10, and the inwall of extruding zone machine barrel 8 arranges spiral channel 11, extrusion
Section machine barrel 8 directly processes spiral channel, and so, the first wall thickness of cooling water channel distance machine barrel endoporus is less,
The effect of cooling water cooling sizing material is obvious；Second, cooling water enters fuselage inner chamber from below, can only be along spiral
Water channel flows through machine barrel circumference successively, and cooling water channel is long, and cooling water is in the turbulent condition being continually changing direction, passes
Thermal effect increases substantially；Feeding section machine barrel 5 is owing to being provided with spout etc., and shape is more complicated, and traditional rubber squeezes
The feeding part going out machine does not the most set cooling structure.As used cooling water channel, then use casting method, cast out
Water stream channel, but casting surface capacity of heat transmission is very poor, and cooling effect is bad, and the application is at feeding section machine barrel 5
Along the circumference of machine barrel, some axial long holes 12 are uniformly got out in barrel, head and the tail connection between each elongated hole 12, formed
One continuous water channel, causes the cooling effect of cooling water to highlight, and this structure difficulty of processing is relatively big, but is an up
The cooling effect of feeding section；Design special reduction box 7, be equipped with variable-frequency motor and drive so that screw rod 4 turns
Speed turns for 0-25 per minute, it is achieved zero-speed starts, low-speed running, stepless time adjustment, specific adaptation fluorubber
Extrusion requirement, the screw speed that the rotating speed of 0-25 turns far below current Rubber Extruder 30-80, for current state
The screw speed that interior Rubber Extruder is minimum.Expensive in view of fluorubber, arrange and can facilitate open and close
Overall drawing-in device, this entirety drawing-in device is that the fuselage outside feeding section machine barrel 5 cuts with scissors by arranging bearing pin 13
Connecing feeding roller seat 6, feeding roller 14 is arranged on feeding roller seat 6, and the upper end of feeding roller seat 6 arranges unlatching and draws
Hand 15, fastens feeding roller seat 6, and feeding roller 14 is positioned at spout 16 side.Feeding roller seat 6 is by fuselage
Rotary pin shaft 13,15 can open with opening handle easily or close.Feeding roller seat 6 closes, with feed
Material section machine barrel forms a spout 16 closed, and puts into sizing material and produces；After production terminates, open and feed
Material roller seat 6, can clean feeding roller 14 and the side of spout 16 easily, clean and reclaim sizing material.
