Abstract
The invention discloses a kind of screw extrusion apparatus, including blanking seat, barrel, driving screw and sub-screw, described barrel connects with blanking seat, one end of described driving screw be positioned at barrel with, its other end is positioned at blanking seat, described sub-screw is positioned at blanking seat, and is installed in parallel in the top of side with driving screw direction of rotation, tabletting is distributed on described sub-screw.The present invention uses length twin screw to combine, driving screw uses helicitic texture, sub-screw uses tabletting structure, utilizes the tabletting of sub-screw that melt is pressed into the screw thread of driving screw, driving screw rotarily drives melt and forward, various melts can be realized quick feeding, simultaneously as driving screw is solely subjected to axial force, sub-screw is solely subjected to side force, in the support of driving screw and sub-screw more convenient, save the cost of whole device.
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 Single screw extrusion device and double screw extruder two kinds.Melt is filled in screw flight by Single screw extrusion device, utilize the frictional force between screw thread and melt will be pushed ahead by melt in screw rod rotation process, this Single screw extrusion device can bear bigger extrusion pressure, realize high-power charging, but its shortcoming is: the melts such as bigger plastics are difficult to fill in screw thread, cause charging difficulty, it is not easy to sent out by melt.Double screw extruder is then to be rotated in by melt between two engagement screws, utilize two screw rods to nibble the extruding force taken to be forwarded by melt when screw rod rotates, solid melt can be sent out by this double screw extruder, but its shortcoming is: transmit for aqueous melt is more difficult, simultaneously because be to utilize extruding force to be sent out by melt between two screw rods, two screw rods can bear axial force and side force simultaneously, and this will increase support bearing on equipment, increase equipment cost.
Summary of the invention
The deficiency that the present invention exists to overcome prior art, it is provided that the screw extrusion apparatus of a kind of simple in construction.
The present invention can be achieved by taking techniques below scheme:
A kind of screw extrusion apparatus, including blanking seat, barrel, driving screw and sub-screw, described barrel connects with blanking seat, one end of described driving screw be positioned at barrel with, its other end is positioned at blanking seat, described sub-screw is positioned at blanking seat, and is installed in parallel in the top of side with driving screw direction of rotation, tabletting is distributed on described sub-screw.
On above-mentioned basis, tabletting of the present invention is uniformly distributed in dislocation on sub-screw, the width of described tabletting is equal with the pitch of driving screw, described tabletting is along the inclined distribution in sub-screw surface, its inclination angle is equal with the lead angle of driving screw, when sub-screw and driving screw can be made to rotate, material can be got in the screw thread of driving screw by tabletting effectively.
Compared with prior art, the invention has the beneficial effects as follows: the present invention uses length twin screw to combine, driving screw uses helicitic texture, and sub-screw uses tabletting structure, melt is pressed into the screw thread of driving screw by the tabletting utilizing sub-screw, rotarily driven melt by driving screw to forward, various melts can be realized quick feeding, simultaneously, owing to driving screw is solely subjected to axial force, sub-screw is solely subjected to side force, more convenient in the support of driving screw and sub-screw, saves the cost of whole device.
Accompanying drawing explanation
Fig. 1 is the structural representation of the screw extrusion apparatus of the present invention；
Fig. 2 is the sectional view in the A-A direction in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, highly preferred embodiment of the present invention is described in detail.
nullAs 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，Described barrel 2 is in long tubular，Blanking seat 1 is in barrel-shaped，Described barrel 2 connects with the side of blanking seat 1，Described main spiral shell 3 bar uses helicitic texture，One end of described driving screw 3 is positioned at barrel 2，Its other end is positioned at blanking seat 1，Described sub-screw 4 is positioned at blanking seat 1，And it is installed in parallel in the top of side with driving screw 3 direction of rotation，Tabletting 5 is distributed on described sub-screw 4，Even driving screw 3 is when external rotation，Sub-screw 4 is then arranged on the front upper place of driving screw 3，If driving screw 3 inwardly rotates，Sub-screw 4 is then arranged on the back upper place of driving screw 3，When so facilitating melt to fall above blanking seat 1，Melt can be got into rapidly in the screw thread of driving screw 3 by sub-screw 4 by the tabletting 5 above it.In order to make sub-screw 4 preferably be arranged in blanking seat 1, one end of the sub-screw 4 of the present invention is the top of the barrel 2 and connectivity part of blanking seat 1 side being fixed in blanking seat 1 by support bearing, its other end then support is at the opposite side of blanking seat 1, and stretches out blanking seat 1 mechanism incoming with power and be connected.Synchronizing to make driving screw 3 and sub-screw 4 rotate, the incoming end of power at driving screw and sub-screw can connect synchronous motor or synchronous gear wheel group structure etc..
Tabletting 5 of the present invention is uniformly distributed in dislocation on sub-screw 4, the width of described tabletting 5 is equal with the pitch of driving screw 3, described tabletting 5 is along the inclined distribution in sub-screw 4 surface, its inclination angle is equal with the lead angle of driving screw 3, when sub-screw 4 and driving screw 3 can be made to rotate, material can be got in the screw thread of driving screw 3 by tabletting 5 effectively.
Only as described above, it is only the preferred embodiments of the invention, when the scope that can not limit present invention enforcement with this, the most generally according to equivalence change simple done by the content described in the claims in the present invention and description of the invention and modification, all it is still covered by the claims of the invention.Additionally, summary part and title are intended merely to assist patent document search to be used, not it is used for limiting the interest field of the present invention.
