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.
The specific embodiment
Referring to Fig. 1, a kind of spinning screw extruder that the utility model embodiment provides, comprises extrusion system 1, transmission system, heating and cooling system and electric control system.Transmission system comprises as the decelerator 2 of deceleration device and the motor 6 of power set, and decelerator 2 is connected by shaft coupling 5 with motor 6.The function of decelerator 2 is that motor 6 output speeds are slowed down and reach the required output speed requirement of 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 utility model embodiment provides, adopts shaft coupling 5 to carry out transmission, and the power of motor 6 is directly transferred to decelerator 2, has improved transmission efficiency, has reduced cost simultaneously, has reduced energy consumption.
Wherein, transmission system also comprises can make the mobile device of left half a coupler along the axle axially-movable of decelerator, thereby makes disconnect coupling.This mobile device comprises the control stick 8 being threaded with left half a coupler, as depicted in figs. 1 and 2.Control stick 8 also can be connected with the screw 9 arranging on deboost axle 2, as shown in Figure 4 and Figure 5.Transmission system also comprises fixture, and this fixture comprises spacer pin 3 and the spacing hole 7 that can cooperatively interact, and as shown in Figure 3, after shaft coupling 5 is thrown off, the left half a coupler of restriction moves axially.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 in the time breaking down, and hand turning is very convenient.Throwing off after shaft coupling 5, a left side is partly joined to device and move and be fixed with the axle of decelerator 2 toward Compress Spring 4 directions, and then rotate the axle of decelerator 2 by control stick 8, thereby reach the object of hand turning.
Below the operation principle of a kind of spinning screw extruder of providing of the utility model embodiment:
Referring to Fig. 1 and Fig. 3, in the time that shaft coupling 5 engages, motor 6 starts, make the key being fixed on its axle by jackscrew connect to drive right half a coupler to rotate, meanwhile, left half a coupler connects by key, under Compress Spring 4 impaction states, drive decelerator 2 power shaft run-in synchronisms.By the transmission of the interior multi-stage gear reduction of speed of decelerator 2, make output speed reach designing requirement.
Referring to Fig. 4 and Fig. 5, because of maintenance of equipment requirement, in the time that needs carry out hand turning, shaft coupling 5 is thrown off, threaded control stick 8 end is screwed in the screw in left half a coupler, hold control stick 8 and move axially to Compress Spring 4 directions, spacer pin to be moved to 3 places, rotate the left half a coupler of having thrown off spacer pin 3 is coordinated with spacing hole 7, stop and oppositely move because Compress Spring 4 restoring forces make left half a coupler.Meanwhile, screw 9 centerings on control stick 8 and reducer shaft, continue to screw in control stick 8, make it to link into an integrated entity with decelerator 2 power shafts, promote control stick 8 and make its rotation, thereby drive decelerator 2 internal gears rotate, thereby reach hand turning.
