Abstract
The utility model discloses a single-drive twin-screw extruder which comprises a barrel, a first screw, a second screw and a drive device, wherein the first and second screws are arranged in the barrel. The single-drive twin-screw extruder is characterized in that the first screw is fixedly connected with the drive device, and the first and second screws are provided with transmission gears engaged to each other. According to the single-drive twin-screw extruder disclosed by the utility model, the two screws are provided with the transmission gears engaged to each other, so that the two screws are driven under a condition that just one screw is driven, and meanwhile, the equipment structure can be simplified by using a same drive device, so that the energy consumption is reduced. The rotary synchronism of the two screws is relatively high, and the condition that a screw flight and a kneading disc in a functional part are staggered to stress in a mutually leaning against manner is avoided, so that the screw flight and the kneading disc are protected well.
Description
Technical field
The utility model belongs to synthetic fiber spinning field, relates 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 comprehensive functions such as heating and the extruding forces 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 utility model provides a kind of single double screw extruder that drives.
The technical solution of the utility model 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 utility model; 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 utility model embodiment;
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 utility model is described in further detail.
As shown in Figure 1, a kind of embodiment of the present utility model, 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 drive part 5, travelling gear part 6 and funtion part 7 from drive unit 4 junctions, the second screw rod 3 is 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.
During the utility model work, 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 utility model, 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 utility model 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 utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
