Detailed description of the invention
1, being added in cold feed extruder by the tire tread glue that remanufactures containing chopped fiber, extruder is XJW60-200, screw rod
Rotating speed is set to 15 revs/min, by rotation and the shearing of screw rod, it is achieved remanufacture tire tread compound is extruded and processed into type；
2, remanufacturing tire tread compound and enter utility model device after the conveying of screw rod, sizing material first passes through a certain pore size
Filter plate, filter plate aperture need to be less than staple length, more than chopped fiber diameter, is optimal with 1.0 3.6mm, thus realizes short
The axial orientation of fiber, the most first smoothes out with the fingers chopped fiber directly.
3, by pressure in regulation excessive glue valve bolt regulation head, pressure is made to maintain 3-10MPa, to ensure sizing material quality and to set
Standby normal safe work.
4, then tread mix shunts through flow distribution plate, has saving design, it is ensured that flow distribution plate top has sufficiently below flow distribution plate
Sizing material flows, and regulating block can regulate gap, controls the flow clearance of sizing material, and its sizing material flow clearance is generally 3-8mm.
Above flow distribution plate, to be mainly used in fiber radial oriented for sizing material, and lower section sizing material in flow process due to throttling arrangement so that
Orientation filled in advance by top sizing material, and then lower section sizing material moves further along, thus slows down the existing fibre orientation degree of destruction,
Big guarantee fiber vertically, simultaneously below sizing material after throttling expansion, be radially oriented degree increase.
5, top sizing material is forced across alignment plate under extrusion pressure effect, it is achieved fiber radial oriented, meanwhile, through orientation
Chopped fiber sizing material is extrusion neck ring mold under the drive of flowing underneath sizing material.
6, after flow distribution plate shunts, top sizing material mainly realizes the radial oriented of fiber, and lower section sizing material is mainly through saving design
Realize radial oriented, finally under the effect of two stream co-extrusions, realize remanufacturing the extrusion molding of tire tread glue.
The radial oriented enhancing of fiber of this example remanufacture tire tread extrusion molding apparatus mainly by filter plate 1, alignment plate 8-1, point
Stream plate 8-2 and regulation part composition, its annexation is that flange 2 front end is connected by bolt with cross-head, rear end and runner
Plate 18 welds together, and has excessive glue valve 4 and excessive glue valve regulation bolt 3, regulation to be orientated the pressure in head above runner plate 18,
The pressure in aligning device, temperature sensor 5, pressure sensing is reduced by the excessive glue valve regulation bolt 3 of regulation when pressure is excessive
Device 17 is fixed in fixed plate 16, monitors the temperature and pressure in aligning device in real time, and sizing material flows through flow distribution plate 14
After be divided into upper and lower two streams, after upper sizing material is forced through alignment plate 8-1, fiber realizes radial oriented, and lower section sizing material is through shunting
Below plate after throttling arrangement, due to the extrusion swelling characteristic of high polymer thus realize the radial oriented of lower section chopped fiber, last two streams
Extrusion neck ring mold 12 under the effect of co-extrusion, it is achieved remanufacture the forming process of fibre orientation in tire tread glue.Runner plate opposite side
Having 6 screwed holes, be connected with stud 10, stud fixes fixed plate 16, intermediate plate 15, mouth template 9 successively finally by nut
11 fix.Mouth die 12 is fixed on mouth template.Runner plate 18 and mouth template 9 have cooling water hole simultaneously, fill in external temperature control
Put the lower temperature realizing aligning device to control.The operation principle of regulation part is: adjustable column 6 with intermediate plate 15 for threadeding,
It is threaded connection the up and down motion that can realize adjustable column, and is that pressured plate 13 realizes being connected between adjustable column 6 with regulating block 7,
Therefore the circumferential movement of screw thread is converted into the up and down motion of regulating block 7.
