Outstanding effect of the present utility model is:
Compared with prior art, it can carry out cleaning when carrying to the inwall of conveying housing and the powder of conveying can be broken up, and can not gather, thus prevent accumulation and the blocking of powder, ensure normally to carry, and its outer sleeve body period of service is of a specified duration, can provide for simple replacement of, the moment ensures the normal of conveying.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the part sectional view of output shaft of the present utility model and outer sleeve body.
Detailed description of the invention:
Embodiment, see as shown in Fig. 1 to 2, a kind of 3D prints and uses powder spiral feedway, comprise conveying housing 10, the top of described conveying housing 10 has inlet point 11, and the lower plane of one end of conveying housing 10 has discharging opening 12, the other end of conveying housing 10 is fixed with servomotor 20, be inserted with conveying axis 30 in conveying housing 10, the two ends of conveying axis 30 are hinged on the two ends of conveying housing 10, and the output shaft of servomotor 20 drives conveying axis 30 to rotate;
The middle part of described conveying axis 30 is spline shaft 31, the madial wall of outer sleeve body 32 has spline 33, spline shaft 31 sleeve is in spline 33, conveying axis 30 sleeve is in outer sleeve body 32, the outer wall of outer sleeve body 32 has conveying screw thread 34, outer sleeve body 32 between two threads in conveying screw thread 34 is fixed with hairbrush portion 35, and the end in hairbrush portion 35 is pressed against on the madial wall of conveying housing 10.
Further, the front end of described conveying housing 10 is fixed with and connects end cap 13, the front end of outer sleeve body 32 is connecting on end cap 13 by bearing hinge connection, the rear end of outer sleeve body 32 is fastened on one end of adapter shaft 36 by key, adapter shaft 36 is by bearing hinge connection in the rear end of conveying housing 10, and the output shaft of servomotor 20 is fixed in the rear end of adapter shaft 36.
