Abstract
The invention discloses a screw used for a mixing mill. The screw comprises a screw body; the screw body is provided with a plurality of screw arrises; the screw is divided into a charging part, a material mixing part, and an material extruding part; distance between each two adjacent screw arrises on the charging part is uniform; distance between each two adjacent screw arrises on the material mixing part is uniform; distance between each two adjacent screw arrises on the material extruding part is uniform; the distance between each two adjacent screw arrises on the charging part is larger than the distance between each two adjacent screw arrises on the material mixing part; and the distance between each two adjacent screw arrises on the material mixing part is larger than the distance between each two adjacent screw arrises on the material extruding part. According to the screw, the distance between each two adjacent screw arrises on the material mixing part is increased, so that retention time of materials in the material mixing part is prolonged, and the materials are mixed uniformly; and in addition, the screw is provided with a material delivering blade I and a material delivering blade II, so that smooth discharging of the materials is ensured, stacking of the materials in a charging barrel is avoided, and mixing effects and product quality are improved.
Description
Technical field
The present invention relates to a kind of mixing roll screw rod, belong to rubber compounding process equipment.
Background technology
Existing mixing roll is single by the structure of screw rod, and the time that material stops in screw rod is shorter, and material must experience fiercer immixture in the short period of time just can obtain reasonable effect.And because screw rod is shorter, the batch mixing part of material is also shorter, the control ratio to mixing process while causing operating is more difficult.In addition, because the distance between the spiral shell rib on screw rod all equates, in mixing of materials process, easily occur pile up and stagnate, form stagnant area, affect effect and the quality of mixing of materials.Therefore, need a kind of new technical scheme to solve above-mentioned technical problem.
Summary of the invention
The object of this invention is to provide a kind of screw rod, it is arranged in the barrel of mixing roll.
The technical solution used in the present invention is:
A kind of mixing roll screw rod, comprise screw rod body, on described screw rod body, be provided with multiple spiral shell ribs, described screw rod is divided into feeding part, batch mixing part and material extrusion part, distance between the adjacent two spiral shell ribs on described feeding part equates, distance between the adjacent two spiral shell ribs in described batch mixing part equates, distance between the adjacent two spiral shell ribs in described material extrusion part equates, distance on described feeding part between adjacent two spiral shell ribs is greater than the distance between adjacent two spiral shell ribs in batch mixing part, distance in described batch mixing part between adjacent two spiral shell ribs is greater than again the distance between adjacent two spiral shell ribs in material extrusion part.
On screw rod body between described feeding part and batch mixing part, be provided with conveying lodicule I, on the screw rod body between described batch mixing part and material extrusion part, be provided with conveying lodicule II.
The helical angle of described conveying lodicule I is greater than conveying lodicule II.
In described conveying lodicule I and conveying lodicule II, be provided with the groove that shape differs.
The degree of depth of described groove is 1/8～1/2 of the spiral shell rib degree of depth.
Advantage of the present invention is: extend the time of staying of material in mixing part by strengthening the distance between adjacent two spiral shell ribs in batch mixing part, make material mixing evenly; But also on the screw rod body between feeding part and batch mixing part, be provided with conveying lodicule I, on the screw rod body between batch mixing part and material extrusion part, be provided with conveying lodicule II, can guarantee that like this material can successfully transfer out, avoid material in barrel, to produce accumulation, improved the quality of melting effect and product.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Wherein: 1, screw rod body, 2, spiral shell rib, 3, feeding part, 4, batch mixing part, 5, material extrusion part, 6, conveying lodicule I, 7, conveying lodicule II, 8, groove.
The specific embodiment
As shown in Figure 1, a kind of mixing roll screw rod, comprise screw rod body 1, on screw rod body 1, be provided with multiple spiral shell ribs 2, screw rod 1 is divided into feeding part 3, batch mixing part 4 and material extrusion part 5, the distance a that adjacent two spiral shell rib on feeding part 3 is 2 equates, the distance b that adjacent two spiral shell rib in batch mixing part 4 is 2 equates, the distance c that adjacent two spiral shell rib in material extrusion part 5 is 2 equates, on feeding part 3, the distance of 2, adjacent two spiral shell rib is greater than the distance between adjacent two spiral shell ribs in batch mixing part 4, in batch mixing part 4, the distance of 2, adjacent two spiral shell rib is greater than again the distance of 2, adjacent two spiral shell rib in material extrusion part 5, on the screw rod body 1 between feeding part 3 and batch mixing part 4, be provided with conveying lodicule I 6, on the screw rod body 1 between batch mixing part 4 and material extrusion part 5, be provided with conveying lodicule II 7, in order to improve conveying effect, the helical angle of conveying lodicule I 6 is greater than conveying lodicule II 7, in order to improve melting effect, in conveying lodicule I 6 and conveying lodicule II 7, be provided with the groove 8 that shape differs, and the degree of depth of groove 8 is 1/8～1/2 of spiral shell rib 2 degree of depth.
