Abstract
The invention discloses a single-drive double-screw extruder. The single-drive double-screw extruder comprises a barrel body, a first screw, a second screw and a driving device, wherein the first screw and the second screw are arranged in the barrel body. The single-drive double-screw extruder is characterized in that the first screw is fixedly connected with the driving device; the first screw and the second screw are provided with transmission gears which are mutually meshed. The single-drive double-screw extruder disclosed by the invention has the advantages that due to the mutually-meshed transmission gears arranged on the two screws, the purpose that the other screw can also be driven when one screw is driven can be realized; by adoption of the same driving device, the structure of the equipment can be simplified, the energy consumption can be reduced, the rotating synchronization of the two screws is also high, the condition that screw edges of the functional part and a kneading disc are staggered and are butted mutually in a stressing manner can not occur, and the screw edges and the kneading disc are well protected.
Description
Technical field
The invention belongs to synthetic fiber spinning field, relate in particular to a kind of single double screw extruder that drives.
Background technology
Screw extruder can join screw portion through charging aperture by solid materials such as macromolecule pellet or sheet stocks, is molten condition, with standby through heating and the comprehensive functions such as extruding force of screw rod by high polymer material plasticizing.Existing screw extruder is mainly divided into single screw extrusion machine and double screw extruder, particularly double screw extruder can meet different Raw material processing demands, in prior art, double screw extruder adopts two cover drive units to two bolt rotaries, but it is asynchronous to there will be two covers to drive, the situations such as discontinuity, and cause its complex structure, the result that energy consumption is higher.
Summary of the invention
In order to overcome this problem, the invention provides a kind of single double screw extruder that drives.
Technical scheme of the present invention is to provide a kind of single double screw extruder that drives, comprise: cylindrical shell, the first screw rod, the second screw rod and drive unit, described the first screw rod and the second screw rod are arranged in described cylindrical shell, it is characterized in that, described the first screw rod is fixedly connected with described drive unit, and described the first screw rod and the second screw rod are provided with intermeshing travelling gear.
Preferably, described the first screw rod is provided with drive part, travelling gear part and funtion part successively, described the second screw rod is provided with travelling gear part and funtion part successively, and travelling gear part and the funtion part of described first, second screw rod are mated mutually, symmetrical configuration.
Preferably, the drive part of described the first screw rod is fixedly connected with described drive unit.
Preferably, described the first screw rod and the second screw axis are parallel to each other, and the teeth groove direction of described travelling gear is parallel with the axis of described travelling gear part.
Preferably, described the first screw rod and the second screw rod are taper, its Axis Cross, and the teeth groove direction of described travelling gear is consistent with the bearing of trend of the outer surface of described travelling gear part.
Preferably, described travelling gear part external diameter is more than or equal to funtion part external diameter.
Single double screw extruder that drives of the present invention; the intermeshing travelling gear that two screw rods is provided with can be realized to be only had in a driven situation of screw rod; two screw rods can both be driven; adopt the same drive unit can simplified apparatus structure simultaneously; reduce energy consumption; the rotational synchronization of two screw rods is also higher, there will not be that the spiral shell rib of funtion part and kneading disk are staggered props up mutually stressed situation, has well protected spiral shell rib and kneading disk.
Accompanying drawing explanation
Fig. 1 is the parallel structural representation of two screw rods axis of the embodiment of the present invention;
In figure: 1. cylindrical shell, 2. the first screw rod, 3. the second screw rod, 4. drive unit, 5. drive part, 6. travelling gear part, 7. funtion part.
The specific embodiment
Below the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, a kind of embodiment of the present invention, what the first screw rod 2 was parallel with the second screw rod 3 is placed in cylindrical shell 1, the first screw rod 2 is fixedly connected on drive unit 4, the first screw rod 2 and the second screw rod 3 are all fixed on the thrust bearing of each self-configuring (not shown), the first screw rod 2 once comprises from drive unit 4 junctions that drive part 5, travelling gear part 6 and funtion part 7, the second screw rods 3 are provided with the first screw rod 2 and mutually mates, the travelling gear part 6 of symmetrical configuration and funtion part 7.Travelling gear part 1 external diameter of screw rod is not less than the funtion part 7 of screw rod, can guarantee that like this screw thread of two screw rods funtion part 7 and kneading disk each other can be normally mutual.
When the present invention works, drive unit 4 drives the first screw rod 2 to rotate, because the travelling gear part 6 of two screw rods part is intermeshing, now the first screw rod 2 drives the second screw rod 3 to rotate, two screw rods direction of rotation, because two screw rods is all arranged on thrust bearing, can freely rotate, screw rod is in the interior molten condition that macromolecule material extruding is mixed and plastified through adding thermosetting of cylindrical shell 1.
In another embodiment of the present invention, the first screw rod 2 and the second screw rod 3 are pyramidal structure, and travelling gear part 6 is also pyramidal structure.
The travelling gear part 6 that the present invention arranges on screw rod can perfectly offer two screw rods by power; the transmission structures of double screw extruder is simplified; reduce by a drive motors; reduced energy consumption; two screw rods is better in transmission process synchronism; there will not be that the spiral shell rib of funtion part and kneading disk are staggered props up mutually stressed situation, well protected spiral shell rib and kneading disk.
Above embodiment is only the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
