The utility model aims at overcoming the problems of low work efficiency, time wasting and large labor intensity existing in the prior art. The utility model has the technical scheme that the utility model comprises a machine head and a knee-control lifting right lever. The utility model is characterized is that the utility model also comprises a servo motor, an electric magnet, an iron core, connecting parts, a link rod and a connecting rod, wherein the connecting rod is movably threaded on the side wall of a machine head; the connecting parts are respectively arranged inside and outside a rear cover plate of the machine head, and the end parts are respectively fixedly connected with both ends of the connecting rod; the other ends of the connecting parts are movably connected with the link rod connected with the knee-control lifting right lever; the other ends of the connecting parts are movably connected with the end of the iron core; the electric magnet is fixedly arranged on the machine head.
Description
Affiliated technical field:
The utility model relates to technical field of sewing equipment, is specifically related to the automatic presser foot lifter of a kind of double needle machine mechanism.
Background technology:
Common presser foot lifting device is that of Sewing machines forms mechanism, what use at present is knee control presser foot lifter mechanism, it finishes presser foot lifter action by a series of component of machine transmissions such as knee control push rods, and this mechanism makes moving from the operator to be needed to waste a large amount of time the process that presser feet lifts.Adopt this structure, the operator is easy to cause fatigue after working for a long time, and labour intensity is big.In sum, prior art exists inefficiency, loses time and problem that labour intensity is big.
Summary of the invention:
The utility model will provide the automatic presser foot lifter of a kind of double needle machine mechanism, to overcome inefficiency that prior art exists, to lose time and problem that labour intensity is big.
For overcoming the problem that prior art exists, the technical solution of the utility model is: the automatic presser foot lifter of a kind of double needle machine mechanism, comprise that head 7 and knee control promote right lever, its special character is: also comprise servomotor, electromagnet 1, iron core 2, connector 3,5, connecting rod 6 and connecting rod 4, these connecting rod 4 activities are arranged on the back shroud sidewall of head 7, connector 3,5 be arranged at respectively head 7 back shrouds inside and outside, the end is fixedly connected with the two ends of connecting rod 4 respectively, the other end of described connector 5 and 6 movable connections of connecting rod, connecting rod 6 promotes right lever with the knee control and connects; The other end of described connector 3 connects with iron core 2 ends of electromagnet 1 are movable, and electromagnet 1 is fixedly set on the head 7.
Above-mentioned connector the 3, the 5th, rotating crank.
Compared with prior art, the utility model has the advantages that:
1, save time, increase work efficiency: servomotor momentary connection electromagnet, provide signal from the workman and lift to presser feet, almost be simultaneous, saved a large amount of time like this, also improved operating efficiency greatly.
2, reduce labor intensity: owing to adopted automaton, the action of presser foot lifter is finished by electromagnet, alleviated working strength of workers greatly.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Description of reference numerals is as follows:
The 1-electromagnet, 2-iron core, 3, the 5-connector, 4-connecting rod, 6-connecting rod, 7-head.
The specific embodiment:
Referring to accompanying drawing, the utility model comprises head 7, servomotor, and electromagnet 1, iron core 2, the knee control promotes right lever, connector 3,5, connecting rod 6 and connecting rod 4, these connecting rod 4 activities are arranged on the back shroud sidewall of head 7. Connector 3,5 is two rotating cranks, they be arranged at respectively head 7 back shrouds inside and outside, the end is fixedly connected with the two ends of connecting rod 4 respectively, the other end of connector 5 and 6 movable connections of connecting rod, the other end of connecting rod 6 promotes right lever with the knee control and connects, the other end of connector 3 connects with iron core 2 ends of electromagnet 1 are movable, and electromagnet 1 is fixedly set on the head 7.
During work, the operator touches the servomotor switch, servomotor is given electromagnet 1 signal, electromagnet 1 is started working, iron core 2 horizontal movements in the electromagnet 1, the rotating crank of drive and its flexible connection is that an end of connector 3 moves, the other end of rotating crank drives connecting rod 4 and rotates, another rotating crank that is connected in casing inside, with the connecting rod other end is that connector 5 drivening rods 6 are done horizontal movement, connecting rod 6 pulling knee controls promote right lever lifts presser feet, finishes the action of presser foot lifter.
