Tri-roll press machine is that L-type tri-roll press machine is made up of three rollers, temperature control and speed regulation devices; Roller can be set to 113 ㎜ × length 366 ㎜ and 166 ㎜ × length 536 ㎜, two kinds of specifications.
Top roll 13 is the convex roller of swelling-waist shape, and convex surface is similar to the tread cap film cross sectional shape extruded.Home roll 12 and the spacing of top roll 13, regulated by top roll 13.Tread cap film is by after extruder extruder die, and it generally all has section and increases, and the crowding-out effect that width and length are then shunk, therefore, tread cap film section thickens, and especially middle part is more remarkable.So top roll mill is carved into the convex roller with certain radian, is adjusted, be substantially shaped to tread cap film semi-finished shape, between input side roller and home roll by the spacing of top roll and home roll.
Side roller 14 is plano-concave roller.Engraving makes the plano-concave roller of corresponding tread cap film cross sectional shape, dimensional standard.Side roller 14 forms two annular grooves 16 by 4 dividing plates 15.Dividing plate 15 thickness 0.6 ㎜, dividing plate 15 top and the surperficial flat face distance of side roller 14 1.6 ㎜, because of gradient bottom annular groove 16, the height of two corresponding dividing plates 15 is respectively 7.9 ㎜ and 6.9 ㎜.Embed after sizing material when annular groove 16 fills up, under the effect of roll extrusion, shape becomes rectangular-shaped embedding sizing material, embed, compound in tread cap film, the tyre surface cross section film simultaneously rolled out also reserves the tyre surface primer of 1.6 ㎜ thickness.The tyre surface primer of 1.6 ㎜ thickness is abrasion wear mark.
Embedding rubber extruding machine 17 is screw rod 45 ㎜ hot-feed extruder, can be arranged at
lon type three-roller calendaring machine or opposed, embed rubber extruding machine 17 die panel 168 ㎜ × thickness 20 ㎜, be carved with two circular embedding sizing material extruder dies, die diameter 12 ㎜ × thickness 5 ㎜, shape of the mouth as one speaks the inner mill is carved with the arc shape correction groove of long 100 ㎜ × wide 30 ㎜ indents.
