To achieve the above object, the method that the utility model uses is: a kind of single, double screw mixes Dual inoculation,
It is characterized in that: including double screw extruder, single screw extrusion machine, connecting tube；The double screw extruder and the single screw rod are squeezed
Machine vertical distribution out, and the feed inlet of the discharge port of the double screw extruder and the single screw extrusion machine is connected by connecting tube
Logical, the connecting tube is divided into connection outer tube and holds material inner tube two parts, and the connection outer tube encompasses appearance material inner tube wherein,
And holds material outer wall of inner tube and fitted closely with outer tube wall is connect.
As a kind of improvement of the utility model, the connection outer tube both ends have been respectively and fixedly connected with twin-screw connecting plate and single spiral shell
Bar connecting plate, the connection outer tube and to hold material inner tube be variable diameter round tube, partly without leave twin-screw one end of the connection board to single screw rod
One end of the connection board gradually becomes smaller.
As a kind of improvement of the utility model, the appearance material inner tube is equipped with limit close to one end of twin-screw connecting plate
Plate, the limit plate are embedded in the twin-screw connecting plate.
As a kind of improvement of the utility model, the connection outer pipe surface is equipped with heating ring.
As a kind of improvement of the utility model, the heating ring at least there are three, and be evenly arranged on the connection outer tube table
Face.
As a kind of improvement of the utility model, the connection outer tube passes through with double screw extruder, single screw extrusion machine
Bolt is detachably connected.
The utility model has the advantages that
A kind of single, double screw mixes Dual inoculation described in the utility model, single screw extrusion machine and twin-screw extrusion
It being connected together between machine by a connecting tube with inside and outside double-skin duct, fused materials only circulate in inner tube, even if
Connecting tube generation blocking, which also only needs to change inner tube, can be used continuously, and save the time of cleaning blocking material.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the sectional view of connecting tube.
Each component in figure are as follows:
1- double screw extruder, 2- single screw extrusion machine, 3- connecting tube, 301- connection outer tube, 302- hold material inner tube, 303-
Limit plate, 4- twin-screw connecting plate, 5- single screw rod connecting plate, 6- heat ring.
Specific embodiment
The utility model is further described below with reference to embodiment and referring to attached drawing, it should be understood that following specific embodiment parties
Formula is merely to illustrate the utility model rather than limitation the scope of the utility model.It should be noted that making in being described below
Word "front", "rear", "left", "right", "up" and "down" refer to that the direction in width figure, word "inner" and "outside" respectively refer to
Be directed towards or far from geometric center of specific component direction.
As Fig. 1 is described in the utility model: a kind of single, double screw mixes Dual inoculation, it is characterised in that: including twin-screw
Extruder 1, single screw extrusion machine 2, connecting tube 3；The double screw extruder 1 and 2 vertical distribution of single screw extrusion machine, and
The discharge port of the double screw extruder 1 is connected to the feed inlet of the single screw extrusion machine 2 by connecting tube 3, the connection
Pipe 3 divides for connection outer tube 301 and holds material 302 two parts of inner tube, and appearance material inner tube 302 is encompassed it by the connection outer tube 301
In, and hold material 302 outer wall of inner tube and fitted closely with 301 inner wall of outer tube is connect.
Working principle of the utility model is: the utility model is by connecting single, double screw rod with inside and outside double-skin duct
Extruder, when the feed blocking that connecting tube is consolidated, connecting tube need to only be disassembled, be replaced in the appearance material in connecting tube
Extruder can be made to continue to use after pipe, no longer need to shut down cleaning consolidation material.
As a kind of improvement of the utility model, 301 both ends of connection outer tube be respectively and fixedly connected with twin-screw connecting plate 4 with
