Abstract

The utility model relates to a double-screw internal mixing discharge machine set which comprises an internal mixer and a rubber extruder; and the double-screw internal mixing discharge machine set is characterized in that a discharge opening of the internal mixer is connected with a feed opening of the rubber extruder, two parallel screw rods are installed in a machine barrel of the rubber extruder, and helical blades on the two screw rods are oppositely arranged. The series combination form that the internal mixer is vertically connected with the double screw extruder is adopted, and the configured rubber raw materials are internally mixed through the internal mixer and then secondarily internally-mixed and extruded through the double screw extruder, so that the continuous processing production of the internal mixer and the rubber extruder is realized, and the double-screw internal mixing discharge machine set is also favorable for improving product quality.

Description

Twin-screw banburying discharge unit
Technical field
The utility model relates to a kind of rubber product production equipment, specifically a kind of twin-screw banburying discharge unit.
Background technology
Internal rubber mixer (being called for short " banbury ") is mainly used in plasticating of rubber and mixing, and Rubber Extruder is with the sizing material extrusion molding after banbury control refining, to form the finished product or the semi-finished product of product.At present, banbury and Rubber Extruder all are discrete settings, separately processing respectively; And, because Rubber Extruder is all to adopt single screw rod push structure, the time that material stops in extruder is longer, makes the charging rate of Rubber Extruder not to be complementary with the discharging speed of banbury, therefore also just can not form the serialization processing of banbury and Rubber Extruder.
The utility model content
The purpose of this utility model just provides a kind of twin-screw banburying discharge unit, to solve the problem that banbury and Rubber Extruder can not form the serialization processing.
The utility model is achieved in that a kind of twin-screw banburying discharge unit, comprise banbury and Rubber Extruder, the discharging opening of described banbury is connected on the charging aperture of described Rubber Extruder, two parallel screw rods are housed in the machine barrel of described Rubber Extruder, and the helical blade on described two screw rods oppositely is provided with each other.
Connect to form two assemblys of upper and lower setting respectively by two described banburies and two described Rubber Extruders, wherein the charging aperture of the discharging opening of the described Rubber Extruder in the upper group zoarium and the described banbury in the lower set zoarium is oppositely arranged up and down.Like this, just can carry out mixingly more fully, the performance indications of finished product are significantly improved sizing material.
The utility model is owing to adopted the twin-screw push structure in Rubber Extruder, two relative inward turnings of screw rod, material is forced to advance in the twin-screw of interlock mutually carry, thereby make this twin-screw propulsive mechanism have the double action that material advances and material stirs, therefore transfer efficiency will improve much than single screw extrusion machine, the time of staying of material in Rubber Extruder can shorten over half, the charging rate of Rubber Extruder and the discharging speed of banbury are complementary, make the two organic being connected in series.And adopt the tandem compound form of this banbury and double screw extruder, the rubber raw materials that configures refines through the control of banbury earlier, mixing by the secondary of double screw extruder again, can become qualified sizing material and be extruded moulding, realize the purpose of the serialization processing of banbury and Rubber Extruder thus.
In addition, Rubber Extruder adopts the twin-screw propulsive mechanism, has also avoided material because of the long phenomenon that chemical change easily takes place of the time of staying in machine, has improved the stability of sizing material in extrusion, helps the raising of product quality.

The specific embodiment
Embodiment 1:
As shown in Figure 1, this twin-screw banburying discharge unit comprises a banbury 1 and a Rubber Extruder 2.Wherein, banbury 1 can use common banbury, Rubber Extruder 2 then is to adopt double screw extruder, two parallel screw rod 4(Fig. 2 promptly are housed) in the machine barrel 3 of Rubber Extruder 2, helical blade on two screw rods 4 oppositely is provided with each other, and two screw rods 4 are forms of motion of synchronous inward turning, so that sizing material is pushed with mixing.
Banbury 1 is positioned at the top of Rubber Extruder 2, and the charging aperture of the discharging opening of banbury 1 and Rubber Extruder 2 links together.In the discharging opening of banbury 1, still be provided with automatically controlled keying valve by traditional approach.Banbury 1 can adopt a common gear to drive with Rubber Extruder 2, to simplify complete machine structure, reduces equipment cost.
Embodiment 2:
As shown in Figure 3, this twin-screw banburying discharge unit is two assemblys that connected to form upper and lower setting by two banburies 1 and two double screw extruders 2 respectively.
In the present embodiment, the mould of not packing on the head of the Rubber Extruder 2 in the upper group zoarium, but be designed to a head form that lower discharge port is arranged, and this discharging opening also with the lower set zoarium in the charging aperture of banbury 1 become the relative up and down form that is provided with.
