Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in figure 1, the invention provides the radial oriented enhancing tread rubber extrusion molding apparatus of chopped fiber, including be connected to
Entrance together, changeover portion, orientation section and mouth template 8, entrance set one along the filter plate 1 for extruding direction carded staple,
Continuous resistance dam structure 7 is set in orientation section so that chopped fiber in sizing material overturns with the compression-expansion of sizing material, in mouth mold
Section sizing material is shaped, and final chopped fiber is to be orientated in rubber matrix perpendicular to extrusion direction with radial direction.
Continuous resistance dam structure is the symmetrical not contour dual waves wave structure of minute surface, 2 sections of resistance dam first paragraph a length of 30mm, second
Segment length is 25mm, and every section of resistance dam peak value reduces step by step, the ultimate range between two peak values of specular be respectively 50mm and
40mm, valley increases step by step, and the ultimate range between two valleies of specular is respectively 30mm, 20mm and 10mm, mouth mold
The sizing material Way out of centre is arranged on, the runner for being orientated section is formed by the symmetrical continuous resistance dam structure of minute surface, continuous resistance dam is adjusted
Locking nub outside connects the one end of adjustable column 6 by pressing plate, and the other end of adjustable column 6 is connected through a screw thread intermediate plate 14, intermediate plate 14, mouth
The fixed plate 15 of template 8 and changeover portion passes through Stud connection, as shown in figure 3, the Wave crest and wave trough of the device specular by inventing
Glue stuff compounding can be seen that this apart from most very much not contour parallel to the electron microscopic picture of extrusion direction cross section under different size ratio
Under dual waves wave structure ratio, chopped fiber die swell ability is maximum, extrudes the radial oriented degree highest of adhesive tape chopped fiber.
Entrance is a flange 2, and the center of the flange 2 is sizing material entrance, and sizing material entrance passes through filter plate 1 and changeover portion
Runner communicate, filter plate 1 be a perforated plate, aperture be less than staple length, more than chopped fiber particle diameter, preferably 1.0-3.6mm.
The runner of entrance is gradually tapered up, and entrance top sets the excessive glue device of connection runner, and excessive glue device includes overflowing
Glue valve 4 and matched regulating bolt 3.
Changeover portion includes fixed plate 15 and the runner formed by the inner side of fixed plate 15, and the outside of fixed plate 15 is equipped with TEMP

Potential energy increase when chopped fiber moves to trough with sizing material after continuous resistance dam alignment plate 8, then passes through crest section and obtains bigger stretching
Stress, flows through chopped fiber and overturns degree in the presence of shearing and elongation flow field after multistage resistance dam and further increase, and realizes again
The forming process of fiber-wall-element model in manufacture tire tread glue.Runner plate opposite side has 6 screwed holes, is connected with stud 10, stud
Fixed plate 15, intermediate plate 14, mouth template 8 is fixed successively finally to be fixed by nut 9.Mouth mold 12 is fixed on mouth template.Flow simultaneously
Guidance tape 17 and mouth template 8 are provided with cooling water hole, and the temperature control of aligning device is realized under external attemperating unit.Regulation part
Operation principle is：Adjustable column 6, to be threadedly coupled, is connected through a screw thread the up and down motion that can realize adjustable column with intermediate plate 14,
And be that pressured plate 13 realizes connection between adjustable column 6 and continuous resistance dam regulating block 7, therefore the circumferential movement of screw thread is converted into connect
The up and down motion of continuous resistance dam regulating block 7.
As shown in Fig. 2 apparatus of the present invention orientation principle：Through expecting entrance filter plate with holes, filter version aperture is less than chopped fiber to glue
Length, more than chopped fiber particle diameter so that chopped fiber is orientated along extrusion direction, after being flowed into orientation section, chopped fiber is transported with sizing material
Trough section potential energy increase is moved, to obtain bigger tensile stress when by crest section, due to continuous resistance dam structure resistance dam
Crest reduces step by step, valley increases step by step, chopped fiber is overturn in the presence of shearing and elongation flow field after flowing through multistage resistance dam
Degree is further increased, extrusion neck ring mold, realizes the radial oriented of chopped fiber.It should be noted that the device withCold feeding
Pin extruder is supporting.
Fiber reinforcement of the present invention remanufactures comprising the concrete steps that for tire tread radial extruding forming will first contain short fibre
Remanufacturing during tire tread glue is added to extruder for dimension carries out extrusion plasticizing by screw rod, the screw rod end in extruder barrel
End, the tire tread glue that remanufactures after extruding processing is squeezed into filter plate, realizes axial orientation of the chopped fiber in sizing material；Glue
Material flows through the continuous resistance dam of gradually gap shrinks in extrusion pressure, it is ensured that while the abundant flowing of sizing material, increases rubber
Potential energy, flow through chopped fiber and overturn degree in the presence of shearing and elongation flow field after multistage resistance dam and further increase so that
Realize that chopped fiber is radial oriented, the experiment proved that, under ratio of the invention and size condition, its radial oriented degree highest.
The expressing technique flow that the radial oriented enhancing of the chopped fiber remanufactures tire tread extrusion molding apparatus is as follows：
1st, the tire tread glue that remanufactures containing chopped fiber is added in cold feed extruder, extruder is XJW60-200,
Screw speed is set to 15 revs/min, and by rotation and the shearing of screw rod, realization remanufactures the extrusion processing of tire tread compound
Shaping；
2nd, remanufacture tire tread compound and pass through a certain pore size by entering invention device, sizing material after the conveying of screw rod
Filter plate 1, chopped fiber is smoothed out with the fingers directly；
3rd, pressure in head is adjusted by adjusting excessive glue valve bolt 3, pressure is maintained 3-10MPa, to ensure sizing material matter
The normal safe work of amount and equipment；
4 then tread mix reach orientation section through changeover portion, the continuous resistance dam structure of continuous resistance dam regulating block 7 can protect
Sufficient sizing material flowing is demonstrate,proved, sizing material is through overcompression, extrusion swelling after continuous resistance dam regulating block 7 for sizing material, and chopped fiber is radially oral
The extruder head of mould 12；
Embodiments above is merely to illustrate the technical scheme being not intended to limit the present invention, and does not depart from any of spirit of the present invention
