Abstract

The utility model discloses a mixing and stirring shaft structure of a rubber machine, which is mainly characterized in that two stirring shafts are disposed in a mixing tank of the rubber machine, main blades and secondary blades are formed on each of the two stirring shafts, a plurality of convex-concave blade wings are formed on each main blade, and the two stirring shaft are disposed in opposite directions. Therefore, by the aid of staggered stirring and cutting faces formed by the main blade wings and the secondary blades of the two stirring shafts, raw rubber materials and additives passing through the two stirring shafts can be cut and scattered fine prior to being stirred and kneaded, accordingly the effect of quickly and uniformly mixing the raw rubber materials and the additives is achieved.

Description

The rubber machine shaft structure of mixing

Technical field

The utility model relates to a kind of rubber machine, refers to a kind of rubber machine of mediating of rubber raw materials and additive can being mixed fast and evenly shaft structure of mixing especially.

Background technology

The rubber machine mainly utilizes two shafts when rotation, rubber (or plastics) raw material is injected between two shafts, continue it, again additives such as colorant are sneaked in this rubber raw materials and stir jointly, so that rubber raw materials fully mixes with additive, and make the elastomeric material of different colours or character.

See also Figure 6 and Figure 7, existing rubber machine 5 mainly is provided with two shafts 52 in it mixes groove 51, and be provided with relative cam-like blade 53 in two shafts 52, by this, when shaft 52 rotates, blade 53 can and then rotate simultaneously, mixes with additives such as the rubber raw materials that will be contained in the groove 51 that mixes and colorants.

Because the blade 53 of existing its two shaft 52 of rubber machine is when stirring, only can reach the effect that drives rubber raw materials and additive upset stirring, and the additive of rubber raw materials and adding can't be cut off, disperse to mediate again, therefore, its effect extreme difference that mixes mixes more fully for rubber raw materials and additive are stirred, and the existing practice increases the time of stirring kneading, in the hope of with longer mixing time, reach rubber raw materials is improved the effect of mixing with additive.

But growth along with mixing time, rubber raw materials can generate heat because of continuous agitating friction, causing rubber raw materials easily is because temperature is too high in stirring in the process of mediating with additive, and sclerosis typing ahead of time, so that this rubber raw materials is difficult to provide the use of making finished product.

The specific embodiment

Be the effect that makes technological means of the present utility model and can reach, can have more complete and clearly exposure, be described in detail as follows now, see also the accompanying drawing and the figure number of exposure:

At first, see also Fig. 1 to shown in Figure 3, be the rubber machine of the present utility model shaft structure of mixing, in the groove 11 that mixes of rubber machine 1, the shaft 2 that two rightabouts are set up is set, on shaft 2, be formed with again by the primary blades 3 of shaft 2 one end screw windings to shaft 2/2nds three strong points, and make and be formed with several sections concavo-convex alternate wings 31 on this primary blades 3, and make every section wing 31 form the type shape of isometric not uniform thickness, make shaft 2 other ends be provided with time blade 4 being positioned at 3 of two primary blades again, set up and make primary blades 3 and time blade 4 be staggered, other makes time blade 4 be spirally extended to 1/3rd length of shaft 2 by shaft 2 other ends, and makes blade 4 formation different-thickness each time.

See also Fig. 3 to shown in Figure 5, be main enforcement structure of the present utility model, three primary blades 3 mainly are shaped on a shaft 2, and be provided with different three sections concavo-convex alternate wings 31 of arranging in each primary blades 3, and make three sections wings 31 form identical length and big, in, the arrangement of little different-thickness D1 is set up, make shaft 2 other ends between two primary blades 3, respectively be provided with primary vane 4 again, and form big altogether, in, the inferior blade 4 of little three different-thickness D2, make another shaft 2 be rightabout again and set up, so that the inferior blade 4 of two shafts 2 is corresponding with the primary blades 3 of another shaft 2 respectively.

In view of the above, when desire is mixed additives such as rubber raw materials and colorant mutually, please consult Figure 1 and Figure 2 again, rubber raw materials and additive are inserted in the groove 11 that mixes of rubber machine 1, continue it, drive two shafts, 2 constant speed rotation start.

At this moment, please consult Fig. 3 more in the lump to shown in Figure 5, be located at primary blades 3 and time blade 4 on the shaft 2, and then shaft 2 rotates simultaneously, stir with the rubber raw materials that will be contained in the groove 11 that mixes and additive and to mix, when primary blades 3 and time blade 4 stirring rubber raw materials and additive, rubber raw materials and additive can be in primary blades 3 and time 4 stirrings of blade of two shafts 2, and be rightabout dislocation by the primary blades 3 of two shafts 2 and time blade 4 and set up, and make the primary blades 3 of two

shafts

2 and 4 in time blade form the good tangent plane that stirs, with with rubber raw materials and be added into additive in the rubber raw materials when 4 in the primary blades by two shafts 23 and time blade, cut off, disperse, continue it, to cut off again, disperse and distinctly be attached to the rubber raw materials of two shafts 2 and the additive of adding, upset on shaft 2, in to two shafts, 2 upsides the time, mediate again, thereupon, cut off again after turning to 2 of two shafts, disperse, according to this, with rubber raw materials and add additive in it, in cut-out, after the dispersion, the action that different tangent planes is mediated mutually through upset again, rubber raw materials and additive are mixed evenly fast, and the feasible time of mediating of mixing significantly shortens, avoid the long stirring time of mixing to cause the rubber raw materials frictional heat, and the situation of the typing of slaking ahead of time, simultaneously, under the minimizing of the time of mixing, more can save the consumption of the energy, and the output in the unit interval is increased.

By this, the primary blades of two shafts and time blade be oppositely set up, rubber raw materials and additive are formed between two shaft primary blades wings when stirring in the space, rubber raw materials and additive are in whipping process, being subjected to primary blades wing and time blade stirs fully, do not have and stir the generation of ground, dead angle, moreover, with every section wing of primary blades and each time blade form different thickness so that the master of two shafts, form the staggered tangent plane that stirs between inferior blade, according to this, when the additive of rubber raw materials and adding is passed through between two shafts, the master who promptly is subjected to two shafts, inferior blade cuts off, disperse, afterwards, stir again and mediate, according to this, the two mixes evenly fast just can to make rubber raw materials and additive, avoids long stirring to mix the time, cause the rubber raw materials frictional heat, the situation of the typing of slaking ahead of time.

The above only is the schematic specific embodiment of the utility model, is not in order to limit scope of the present utility model.Any those skilled in the art, equivalent variations of having done under the prerequisite that does not break away from design of the present utility model and principle and modification all should belong to the scope that the utility model is protected.
