Description
Technical field
The utility model relates to a kind of extruder, particularly relates to a kind of single screw extrusion machine.
Background technology
At present, along with the development of science and technology, people require also more and more higher for the process equipment of plastics etc., can effectively reclaim and utilize resource, also get more and more as its effect of frequent the used extruder of processing plastic, the process of current employing extruder processing plastic goods adopts the single screw extrusion machine not with degassing function mostly, such processing method not only makes melt mixed even not, so that plastic products crystalline substance is put and bubble is more, and its energy consumption can be caused high in this process, cause unnecessary waste.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of single screw extrusion machine.
The utility model is taked following technical scheme to realize: a kind of single screw extrusion machine, and it comprises motor, screw rod, heater and discharging opening, and described motor output divides and is connected with decelerator; Described decelerator is connected with shaft coupling port; Described screw rod is matched with decelerator and motor by shaft coupling; Described charging aperture is arranged at the surface of barrel; Described charging aperture top is provided with agitator; Described screw rod is arranged in barrel; Described screw rod is provided with main thread and deputy thread; Some heaters are provided with outside described barrel; Described heater outer wrapping one layer of heat preservation layer; Described barrel outer end is provided with safty shield; The bottom of described single screw extrusion machine is provided with die head; Described discharging opening is arranged on the bottom of die head; Described filter course is arranged on the left side of discharging opening; Rectangle baffle plate is provided with in the middle of the die head of described screw extruder; Described screw rod is divided into the first feed zone and the second feed zone; Main thread external diameter on described screw rod is greater than the deputy thread external diameter that screw rod is arranged; Pitch between the main thread that described first feed zone is arranged is equal, and the different and pitch of pitch on described second feed zone between main thread and deputy thread reduces gradually; Described heater is heating wire or electric heating piece.
The utility model has following beneficial effect in sum: the utility model extruder has reasonable in design, easy to use and operating efficiency advantages of higher, and the change of pitch between described main thread and deputy thread, make material plastify completely and mix, make plastic products decrease brilliant point and bubble; Described heat-insulation layer can ensure the efficiency that solid material liquefies to improve operating efficiency.

Detailed description of the invention
As shown in Figure 1, a kind of single screw extrusion machine, it comprises motor 1, screw rod 7, heater 10 and discharging opening 5, and described motor output divides and is connected with decelerator 2; Described decelerator 2 is connected with shaft coupling 3 port; Described screw rod 7 is matched by shaft coupling 3, decelerator 2 and motor 1; Described charging aperture 5 is arranged at the surface of barrel 6; Described charging aperture 5 top is provided with agitator 4; Described screw rod 7 is arranged in barrel 6; Described screw rod 7 is provided with main thread 8 and deputy thread 9; Some heaters 10 are provided with outside described barrel 6; Described heater 10 outer wrapping one layer of heat preservation layer 11; Described barrel 6 outer end is provided with safty shield 12; The bottom of described single screw extrusion machine is provided with die head 18; Described discharging opening 17 is arranged on the bottom of die head 18; Described filter course 16 is arranged on the left side of discharging opening 17; Rectangle baffle plate 15 is provided with in the middle of the die head 18 of described screw extruder.
When this apparatus is used, transmission is carried out by the screw rod 7 in motor reducer 2 and shaft coupling 3 pairs of barrels 6; Described decelerator 2 effectively can improve the moment of torsion of rotation, decreases the loss of energy; Described screw rod 7 drives the material threadingly direction spiral advance in barrel 6; The agitator 4 arranged above described barrel 6 can be carried back and process raw material, effectively raises operating efficiency; The main thread 8 that described screw rod 7 is arranged is different with the pitch of deputy thread 9, and less the closer to pitch bottom screw rod 7, can realize the compression of material, make material plastify completely and mix; Gas in material can fully be discharged by the outer steam vent 19 arranged of described barrel 6 from the material of plasticizing, eliminates the moisture in material, reduces screw thread process defect; The outer heat-insulation layer 11 arranged of described heater 10 can effectively reduce the loss of heat, thus has saved cost; Described material extrude after through die head 18, the discharging opening 5 that die head 18 place is arranged can discharge material in time, the baffle plate 15 that die head 18 place is arranged is when there is blocking in one section of filter course 16, described baffle plate 15 is stressed and can rotates to the discharging opening 17 cut off, plastic melt can from opposite side discharging, also plastic melt can be made can not to flow in the chamber of breaking, thus improve operating efficiency greatly.
The above is the utility model embodiment, therefore all equivalences done according to structure, feature and the principle described in the utility model application range change or modify, and are included in the utility model patent claim.
