Description

The three-automatic upgrading apparatus that ring throstle is used

The utility model relates to the three-automatic upgrading apparatus that a kind of ring throstle is used.

The three-automatic upgrading apparatus of ring throstle mainly is made up of turbine and worm decelerator, sprocket wheel, ratchet, ratchet, tractive magnet, micromotor and travel switch at present, though this three-automatic upgrading apparatus can be finished the purpose that the ring rail level rises, it still exists following major defect: 1, easy burn-out micromotor.Because of the fault of tractive magnet, often cause electric fault and can not lift support claw, micromotor is transshipped when ring rail descends fast and burnt out; 2, because draw bar can not reset or mechanism itself can not prevent that reciprocal causes the spool of whole chassis to be shaped bad; Palpus one hand ring rail is played support claw on the other hand when 3, shunting, and cross-operation is very easy to hinder hand; 4, technology is adjusted inconvenience, when the change spinning count, needs to change the ratchet of the different numbers of teeth, because the ratchet kind is more, easily produces mistake during replacing, causes whole chassis yarn to scrap, and changes the ratchet inconvenience.

The purpose of this utility model provides a kind of do not have tractive magnet, easy burn-out micromotor and need not change ratchet and have the three-automatic upgrading apparatus that the ring throstle of anti-inversion performance is used not.

Task of the present utility model is achieved in that this three-automatic upgrading apparatus comprises reducing gear, the ratchet and pawl that is made of worm gear, worm and worm wheel worm screw seat, it also comprises hinge wheel, support, pusher dog, star-wheel pusher dog torsion spring, ratchet spring, swing arm, swing arm extension spring, curved cover plate, anti-down pawl, anti-down pawl torsion spring and freewheel clutch, hinge wheel, swing arm, pusher dog, star-wheel pusher dog torsion spring and freewheel clutch are contained on the axle of worm screw successively, and the hock of pusher dog is inserted in the freewheel clutch; Ratchet sleeve is contained on the outer shroud of freewheel clutch; The stiff end of ratchet is contained on the arm end of swing arm, and the crown end of its ratchet contacts with the flank of tooth of ratchet; Ratchet spring is sleeved between the arm end of the stiff end of ratchet and swing arm; One end of swing arm extension spring is contained in the bottom of swing arm, and the other end connects with the lower end of support; The stiff end of anti-down pawl is contained in the top of support, and its crown end contacts with the flank of tooth of ratchet; Anti-down pawl torsion spring is contained between the stiff end and support of anti-down pawl, and the one end is fixed on the support, and the other end is contained on the anti-down pawl; Curved cover plate is contained in the middle and upper part of support and covers ratchet number on a part of ratchet.

Above-mentioned freewheel clutch is made of roller, little spring, outer shroud and star-wheel, and star-wheel is contained in the central authorities of outer shroud, and little spring is contained in the spring eye that is provided with on the star-wheel, roller be located in the space that star-wheel and outer shroud form and be positioned at little spring above.

Because the utility model has adopted the freewheel clutch and the batch (-type) ratchet mechanism of one-way tape pusher dog, therefore compare with background technology, have following advantage:

1, owing to removed tractive magnet, can not produce electric fault, thereby easy burn-out micromotor not;

2, owing on the batch (-type) ratchet mechanism, added curved cover plate, the number of teeth of ratchet can be adjusted according to spinning count, need not change ratchet when therefore changing spinning count;

3, above ratchet, be provided with anti-down pawl, had anti-down function;

4, this apparatus structure is simple, compact, and flexible operation is reliable, is specially adapted to cotton, hair, the use of numb ring throstle.

The utility model will be further described below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is that B among Fig. 1 is to view.

As shown in Figure 1 and Figure 2, the utility model comprises reducing gear, ratchet 9 and the ratchet 10 that is made of worm gear 1, worm screw 2 and worm and gear seat 3, and it also comprises hinge wheel 4, support 5, pusher dog 6, star-wheel pusher dog torsion spring 8, ratchet spring 11, swing arm 12, swing arm extension spring 13, curved cover plate 14, anti-down pawl 15, anti-down pawl torsion spring 16 and freewheel clutch 17; Hinge wheel 4, swing arm 12, pusher dog 6, star-wheel pusher dog torsion spring 8 and freewheel clutch 17 are contained on the axle of worm screw 2 successively, and the hock of pusher dog 6 is inserted in the freewheel clutch 17; Ratchet 9 is sleeved on the outer shroud of freewheel clutch 17; The stiff end of ratchet 10 is contained on the arm end of swing arm 12, and the crown end of its ratchet 10 contacts with the flank of tooth of ratchet 9; Ratchet spring 11 is sleeved between the arm end of the stiff end of ratchet 10 and swing arm 12; One end of swing arm extension spring 13 is contained in the bottom of swing arm 12, and the other end connects with the lower end of support 5; The stiff end of anti-down pawl 15 is contained in the top of support 5, and its crown end contacts with the flank of tooth of ratchet 9; Anti-down pawl torsion spring 16 is contained between the stiff end and support 5 of anti-down pawl 15, and the one end is fixed on the support 5, and the other end is contained on the anti-down pawl 15; Curved cover plate 14 is contained in the middle and upper part of support 5 and covers ratchet number on a part of ratchet 9.

As shown in Figure 3, above-mentioned freewheel clutch 17 is made of roller 18, little spring 19, outer shroud 20 and star-wheel 7, star-wheel 7 is contained in the central authorities of outer shroud 20, and little spring 19 is contained on the star-wheel 7 in the spring eye that is provided with, roller 18 be located in the space that star-wheel 7 and outer shroud 20 form and be positioned at little spring 19 above.

The course of work of the present utility model is: micromotor drives the hinge wheel rotation when expiring yarn, the pusher dog that is connected by flat key also and then rotates, pusher dog is dallied on worm screw and promote three rollers and withdraw from the angle of wedge, star-wheel separates with ratchet, pusher dog makes star-wheel drive worm and gear make ring rail drop to the position of doffing fast by roller, when ring rail resets fast, pusher dog oppositely promotes star-wheel, roller is extruded the angle of wedge and ratchet is separated with star-wheel, and star-wheel makes ring rail be thus lifted to the beginning fast by worm and gear and spins the position.In spinning process, even if ratchet reversing, because roller can not be extruded in the angle of wedge and can not produce reversing this moment.
