Cam design principle: this cam structure is designed with roller push rod, can reduce the friction between cam and push rod in cam rotary course, reduces abrasion. Shown in Fig. 5 a, for the Design of Cam Profiles schematic diagram of the present invention, Fig. 5 b show changeable screw baffle plate push rod and the theoretical position curve chart of cam contact point opposing cam axis, and wherein the maximum radius difference of camshaft ishA point is cam lofty perch, initial position is push rod roller and the cam A point cantact of changeable screw baffle plate 403, now the push rod roller of changeable screw baffle plate 403 is farthest relative to the distance of camshaft axis with camshaft contact point, at point corresponding for Fig. 5 b namely when corner �� is zero, L be camshaft least radius r0 with semidiameter h's and, now the screw conduits of screw pilot sleeve 5 is blocked by changeable screw baffle plate 403; Camshaft continues to rotate 45 degree counterclockwise, the now push rod roller of changeable screw baffle plate 403 and cam B point cantact, now closest relative to camshaft axis of the push rod roller of changeable screw baffle plate 403 and camshaft contact point, at point corresponding for Fig. 5 b namely when corner �� is 45 degree, L is camshaft least radius r0, now changeable screw baffle plate 403 is radially withdrawn, is stored in the screw in screw pilot sleeve 5 and can fall to station to be assembled along screw conduits smoothly; For ensureing smoothly completing of screw separation next time, camshaft needs to continue to rotate 45 degree counterclockwise, make the push rod roller of changeable screw baffle plate 403 and the camshaft contact point distance relative to camshaft axis by recently to farthest, so before upper once Screw feeding process starts, the screw conduits of screw pilot sleeve 5 is blocked by changeable screw baffle plate 403, so far, one screw is completed to multichannel band beat automatic feed dividing blanking process by single channel, and the blanking cycle is 90-degree rotation counterclockwise.
Operation principle is as follows:
Screw separation process is broadly divided into two parts: sleeve rotating feeding process, synchronizes blanking process, sleeve rotating feeding process, motor 1 is rotated clockwise by shaft coupling 2 drive cam shaft 4051, ratchet 4052 is driven to rotate clockwise, ratchet 11 is promoted to engage with ratchet 4052, screw pilot sleeve 5 up time is driven to rotate, owing to camshaft support chassis 404 is connected by screw is fixing with screw pilot sleeve 5, camshaft support chassis 404 is driven and rotates clockwise, so far whole feeding system rotates clockwise under the driving of motor, the screw of now single channel Screw feeding system conveying falls in the screw guide channel of screw pilot sleeve 5 of rotation successively, owing to the initial position of changeable screw baffle plate 403 is positioned at the peak of camshaft 4051, and whole rotate clockwise changeable screw baffle plate 403 in process zero is always for the relative velocity of camshaft 4051, therefore in this feeding process rotated clockwise, changeable screw baffle plate 403 is always positioned at the peak of camshaft 4051, after dextrorotation is circled, it is respectively arranged with one in the passage of screw pilot sleeve 5 and is hindered the screw that can not continue to fall by changeable screw baffle plate 403, now sleeve rotating feeding process completes,Synchronize blanking process, motor 1 is rotated counterclockwise by shaft coupling 2 drive cam shaft 4051, ratchet 11 is now promoted to separate with ratchet 4052 motion, camshaft 4051 no longer drives screw pilot sleeve 5 to rotate counterclockwise, but owing to promoting ratchet and ratchet 4052 CONTACT WITH FRICTION, therefore for ensureing that screw pilot sleeve 5 is avoided being promoted by frictional force rotating counterclockwise, add the design of locating snap ring herein, when camshaft 4051 rotates counterclockwise, it is positioned on screw pilot sleeve 5 detent 8 covered to contact with locating snap ring 9 engagement, therefore hinder screw pilot sleeve 5 and be likely to because of rotating counterclockwise that frictional force drives, it is connected owing to camshaft support chassis 404 and screw pilot sleeve 5 are fixed by screw, therefore camshaft support chassis 404 also remains stationary motionless, now system can be only done cam axle, changeable screw baffle plate 403 is driven to do reciprocating motion radially, when camshaft 4051 rotates counterclockwise 45 degree, changeable screw baffle plate 403 moves to camshaft 4051 minimum point, at this moment the screw in screw pilot sleeve 5 drops to the assembly station of setting simultaneously, camshaft 4051 continues to rotate 45 degree counterclockwise, changeable screw baffle plate 403 is re-moved to camshaft 4051 peak, now the synchronization blanking process of screw completes. for ensureing that changeable screw baffle plate 403 moves to camshaft 4051 minimum point process at camshaft 4051 lofty perch and can smoothly complete, it is provided with baffle plate restoring spring 401, ensure that changeable screw baffle plate 403 playbacks smoothly and arrive the minimum point of camshaft 4051, thus next screw can have been continued when passage to multichannel feeding separation process, baffle plate guide 402 ensure that changeable screw baffle plate 403 does radial alignment and moves back and forth, system dextrorotation three-sixth turn, rotates 90 counterclockwise and namely completes a screw sub-material blanking cycle.
