Wherein, extrusion system-1, decelerator-2, spacer pin-3, Compress Spring-4, shaft coupling-5, motor-6, spacing hole-7, control stick-8, screw-9.
Detailed description of the invention
See Fig. 1, a kind of spinning screw extruder that the embodiment of the present invention provides, comprises extrusion system 1, transmission system, heating and cooling system and electric control system.Transmission system comprises the motor 6 of decelerator 2 as deceleration device and power set, and decelerator 2 is connected by shaft coupling 5 with motor 6.The function of decelerator 2 is slowed down by motor 6 output speed to reach output speed requirement needed for screw rod.Shaft coupling 5 comprises interconnective left half a coupler and right half a coupler, and left half a coupler is connected with the axle of decelerator 2, and right half a coupler is connected with the axle of motor 6.Between decelerator 2 and left half a coupler, be also provided with Compress Spring 4, left half a coupler and right half a coupler are engaged closely.The spinning screw extruder that the embodiment of the present invention provides, adopts shaft coupling 5 to carry out transmission, the power of motor 6 is directly transferred to decelerator 2, improves transmission efficiency, reduce cost simultaneously, decrease energy consumption.
Wherein, transmission system also comprises the mobile device of the axle axially-movable that left half a coupler can be made along decelerator, thus makes disconnect coupling.This mobile device comprises the control stick 8 be threaded with left half a coupler, as depicted in figs. 1 and 2.Control stick 8 also can be connected with the screw 9 that deboost axle 2 is arranged, as shown in Figure 4 and Figure 5.Transmission system also comprises fixture, and this fixture comprises the spacer pin 3 and spacing hole 7 that can cooperatively interact, and as shown in Figure 3, after shaft coupling 5 is thrown off, limits moving axially of left half a coupler.Spacer pin 3 is connected with the axle of decelerator 2, and spacing hole 7 is notched slotted holes, is arranged on left half a coupler, as shown in Figure 3.The mobile device that transmission system comprises and fixture, make at spinning screw extruder when breaking down, hand turning is very convenient.After disengagement shaft coupling 5, a left side half connection device moved toward Compress Spring 4 direction and is fixed with the axle of decelerator 2, and then rotating the axle of decelerator 2 by control stick 8, thus reaching the object of hand turning.
Below the operation principle of a kind of spinning screw extruder that the embodiment of the present invention provides:
See Fig. 1 and Fig. 3, when shaft coupling 5 engages, motor 6 starts, the key be fixed on its axle by jackscrew is connected drives right half a coupler to rotate, and meanwhile, left half a coupler is connected by key, under Compress Spring 4 impaction state, drive the run-in synchronism of decelerator 2 power shaft.By multi-stage gear decreasing transmission in decelerator 2, output speed is made to reach designing requirement.
See Fig. 4 and Fig. 5, because of maintenance of equipment requirement, when needs carry out hand turning, shaft coupling 5 is thrown off, threaded for control stick 8 end is screwed in the screw in left half a coupler, holds control stick 8 and move axially to Compress Spring 4 direction, to be moved to spacer pin 3 place, rotate the left half a coupler of having thrown off spacer pin 3 is coordinated with spacing hole 7, stop because Compress Spring 4 restoring force makes the oppositely movement of left half a coupler.Meanwhile, control stick 8 and screw 9 centering on reducer shaft, continue to screw in control stick 8, make it to link into an integrated entity with decelerator 2 power shaft, promotes control stick 8 and make it rotate, thus drive decelerator 2 internal gear to rotate, and thus reaches hand turning.
It should be noted last that, above detailed description of the invention is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to example to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
