Description
Technical field
The present invention relates to a kind of screw extrusion apparatus, belong to material extrusion device technical field.
Background technology
Existing melt extrusion device includes two kinds of Single screw extrusion device and double screw extruder.Single screw extrusion fills
It puts and fills in melt in screw flight, it will forward by melt using the frictional force between screw thread and melt in screw rod rotation process
It promoting, this Single screw extrusion device can bear larger extrusion pressure, realize high-power charging, but the drawback is that：Larger
The melts such as plastics are difficult to fill in screw thread, cause charging difficult, it is not easy to send out melt.And double screw extruder is then
Between melt is rotated in two engagement screws, the extruding force taken is nibbled using two screw rods when screw rod is rotated and forwards melt,
This double screw extruder can send out solid melt, but the drawback is that：It is transmitted for liquid melt is more difficult,
Simultaneously because being to be sent out melt using extruding force between two screw rods, two screw rods can bear axial force and lateral force simultaneously,
This will increase support bearing in equipment, increase equipment cost.
The content of the invention
The present invention provides a kind of screw extrusion apparatus simple in structure to overcome the shortcomings of the prior art.
The present invention can be by taking following technical scheme to be achieved：
A kind of screw extrusion apparatus, including blanking seat, barrel, driving screw and sub-screw, the barrel is connected with blanking seat, described
One end of driving screw is located at barrel in, and the other end is located in blanking seat, and the sub-screw is located in blanking seat, and parallel peace
Mounted in the top of the one side with driving screw direction of rotation, tabletting is distributed on the sub-screw.
On above-mentioned basis, tabletting of the present invention is uniformly distributed on sub-screw in dislocation, the width of the tabletting and master
The screw pitch of screw rod is equal, and along the inclined distribution in sub-screw surface, inclination angle is equal with the lead angle of driving screw for the tabletting,
When can make sub-screw and driving screw rotation, tabletting can effectively get into material in the screw thread of driving screw.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is combined using length twin-screw, driving screw
Using helicitic texture, sub-screw is used tabletting structure, melt is pressed into the screw thread of driving screw using the tabletting of sub-screw, by leading
Screw rod rotation drives melt to forward, and quick feeding can be realized to various melts, simultaneously as driving screw is solely subjected to axial direction
Power, sub-screw are solely subjected to lateral force, are more convenient in the support of driving screw and sub-screw, save the cost of whole device.
Description of the drawings
Fig. 1 is the structure diagram of the screw extrusion apparatus of the present invention；
Fig. 2 is the sectional view in the A-A directions in Fig. 1.
Specific embodiment
Highly preferred embodiment of the present invention is described in detail below in conjunction with attached drawing.
As shown in Figure 1, the screw extrusion apparatus of the present invention, including blanking seat 1, barrel 2, driving screw 3 and sub-screw 4, institute
Barrel 2 is stated in long tubular, blanking seat 1 is in barrel-shaped, and the barrel 2 is connected with the one side of blanking seat 1, and main 3 bar of spiral shell uses
Helicitic texture, one end of the driving screw 3 are located in barrel 2, and the other end is located in blanking seat 1, and the sub-screw 4 is located to fall
Expect in seat 1, and be installed in parallel in the top with the one side of 3 direction of rotation of driving screw, tabletting 5 is distributed on the sub-screw 4, i.e.,
If driving screw 3 outwards rotates, sub-screw 4 is arranged on the front upper place of driving screw 3, if driving screw 3 inwardly rotates, sub-screw
So that it is convenient to when melt is fallen above blanking seat 1, sub-screw 4 can be by above it for 4 back upper places for being arranged on driving screw 3
Tabletting 5 rapidly melt is got into the screw thread of driving screw 3.In order to which sub-screw 4 is made preferably to be arranged in blanking seat 1, this
One end of the sub-screw 4 of invention is to be fixed on the barrel 2 in blanking seat 1 and the connectivity part of 1 one side of blanking seat by support bearing
Top, the other end then in the opposite side of blanking seat 1, and stretch out blanking seat 1 and be passed to mechanism with power and be connected by support.In order to make
Driving screw 3 rotates synchronous with sub-screw 4, and synchronous motor or synchromesh gear can be connected by being passed to end in the power of driving screw and sub-screw
Group structure etc..
Tabletting 5 of the present invention is uniformly distributed on sub-screw 4 in dislocation, the width of the tabletting 5 and the spiral shell of driving screw 3
Away from equal, along the inclined distribution in 4 surface of sub-screw, inclination angle is equal with the lead angle of driving screw 3 for the tabletting 5, can be with
When making sub-screw 4 and the rotation of driving screw 3, tabletting 5 can effectively get into material in the screw thread of driving screw 3.
Only as described above, is only the preferred embodiments of the invention, when the model that implementation of the invention cannot be limited with this
It encloses, i.e., generally according to simple equivalent changes and modifications made by the content recorded in the claims in the present invention and description of the invention,
All it is still covered by the claims of the invention.It is searched in addition, summary part and title are intended merely to auxiliary patent document
It seeks and being used, be not used for limiting the interest field of the present invention.
