Description of drawings
Fig. 1 is an apparatus structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing to structure of the present utility model with help and inhale principle and be described further.
As shown in Figure 1, a kind of absorption-asssisting equipment of shedding selection mechanism, left side swing hook 3 that comprise housing 1, be arranged on the electromagnet 2 of housing 1 inner upper end, two activities is fixed on electromagnet 2 both sides and right side swing hook 4 and two left sides that move up and down in housing 1 inboard are carried through hook 5 and right side and being carried through hook 6; Swing hook 3 outsides, left side are to the inclined-plane, left side 7 of the inboard inclination of housing, and the outside, right side swing hook 4 lower ends is the inclined-plane, right side 8 that tilts to housing; Swing hook 3 lower ends, left side are provided with left side hook 9 to the inside, and swing hook 4 lower ends in right side are provided with right side hook 10 to the inside; The right side is carried through hook 6 upper end bifurcateds and is inboard hook 11 and outside boosting arm 12, and the left side is carried having with the right side through hook 5 and carried through the inverse structure of hook 6 along the center line symmetry; Outside boosting arm 12 closely contacts with inclined-plane 8, and right side hook 10 is optionally hung up with inboard hook 11 and separated.
The right side is carried and is stretched out housing 1 through hook 6 outsides and be provided with and hang arm 17, hangs arm 17 and hangs on the needle bar 18 that drives by mechanical external force, and needle bar 18 promotes right sides and carries through hook 6 and moving up and down in housing 1.
The right side is carried through hook 6 lower ends and is connected with chain wheel rope 19, and chain wheel rope 19 other ends are by assembly pulley, and assembly pulley is connected with steel and combines, and steel is combined and is connected with return spring, by the downward pulling force pulling right side of return spring carry through hook 6 in housing 1 to lower slider.Accompanying drawing middle pulley group and return spring omit, and be identical with the mode of using in the patent that is cited.
Outside boosting arm 12 has elasticity, helps contacting the inclined-plane 8 of swing hook 4 when up, infers swing hook 4 near electromagnet 2 suction nozzles.
The utility model is put down in writing carries and comprises through hook that the left side is carried through hook 5 and right side and carry through hook 6 that both have along the inverse structure of center line symmetry, and the swing hook of being put down in writing comprises left side swing hook 3 and right side swing hook 4, and both have along the inverse structure of center line symmetry.
The operation principle of the absorption-asssisting equipment of the utility model shedding selection mechanism is as follows, and the motion of carrying through hook 6 with the right side is an example, and the left side is carried through the motion of hook 5 identical with it.As follows:
(1) promotes needle bar 18 by external force and drives the right side to carry through hook 6 and moving upward, apply a boosting power F1 who points to side direction in the housing 1 for when outside boosting arm 12 upwards slips over inclined-plane 8, right side right side swing hook 4, make right side swing hook 4 side direction swing in housing 1, and with the right-hand member adhesive of suction nozzle 13;
(2) at this moment, if electromagnet 2 energisings then produce magnetic force F2, attract right side swing hook 4 by suction nozzle 13; Carry through bar 18 descending, return spring is carried through hook 6 pulling downwards the right side descending by chain wheel rope 19, right side hook 10 and inboard hook 11 are hung up, and carry through bar 18 disengaging right sides and carrying through hook 6, and the right side is carried through hook 6 and is in suspended state (left side is put forward through hook 5 residing states in suspended state such as the accompanying drawing 1);
(3) at this moment, if electromagnet 2 no powers then do not produce magnetic force F2, then right side swing hook 4 can not held by suction nozzle 13; Carry through bar 18 descending, then return spring is carried through hook 6 pullings the right side descending, the be reset elastic force F3 of spring 16 of right side swing hook 4 pushes open, right side hook 10 separates with inboard hook 11 dislocation, the right side is carried through hook 6 and is continued to move downward, and boosting power F1 fades away, and the elastic force F3 of back-moving spring 16 carries the right side through hook 6 and pushes open to housing 1 lateral direction, the right side is carried through hook 6 and 4 dislocation of right side swing hook, and the right side is carried and can be continued descending through hook 6 descending not hooking.
(4) when the right side was carried through hook 6 place suspended states, the right side was carried through hook 6 and being moved upward for the second time, if electromagnet 2 is still switched on, then the right side is carried through hook 6 and still is in suspended state; If electromagnet 2 no powers, then magnetic force F2 disappears, and boosting power F1 fades away, and the elastic force F3 of back-moving spring 16 pushes right side swing hook 4 open to housing 1 lateral direction, and the right side is carried and is in free movement state through hook 6 and continues to move downward; And so forth.
The utility model is not limited to carry the hang-up and the freely-movable state that will form through the hook motion, and all realize that by carrying through the identical absorption-asssisting equipment of the structure of hook and swing hook with the utility model record the device that shedding forms all falls within the scope that the utility model is asked for protection.
