Abstract
High speed sewing machine automatic needle-foot-lifting mechanism, comprise the electromagnet be arranged in head shell, the draw bar of electromagnet connects rear lever, rear lever cylinder lever connecting rod, pull bar connects presser feet system, described presser feet system comprises presser feet, presser feet there is depression bar, depression bar is installed pilot frame, described pilot frame arranges connecting hole, connecting hole connects riser through hold-down screw, lever before riser is installed, front lever is shaped with pull bar steady pin, one end cylinder lever connecting rod steady pin of pull bar, axial screw installed by described rear lever, the other end of pull bar connects axial screw.During work, the draw bar of electromagnet drives rear lever, and rear lever pulls pull bar, and pull bar pulls front lever again, by front lever drives pilot frame and depression bar, presser feet is lifted or depresses, compared with the prior art, after having had front lever, the pull bar actuation that electromagnet is driven is more stable, presser feet lifts or depresses reliably, avoids fault, enhances productivity.
Description
Technical field
The utility model relates to a kind of automatic needle-foot-lifting mechanism for high speed sewing machine, belongs to sewing machine field.
Background technology
The presser feet of traditional industrial high-speed Sewing machines adopts mostly manually lifts pressure, not only troublesome poeration, improve the operation easier of staff, and labour intensity is high, efficiency is low, therefore, in recent years, be developed automatic needle-foot-lifting mechanism, but, unreasonable due to what design, the power of its auto lifting pressure presser feet generally adopts bulky electromagnet, cannot be arranged in the head shell of Sewing machines, the i.e. external head shell outer wall at Sewing machines, shortcoming is: the drive mechanism between electromagnet and presser feet is complicated, action is unstable, sometimes presser feet can not lift or depress, have a strong impact on production efficiency, bulky electromagnet price is high, add cost investment, and affect outward appearance, external electromagnet impact packaging, particularly during work of electromagnet, noise is larger, staff is impacted.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art, and provide a kind of and be placed in head shell by little for electromagnet volume, transmission is simple, and reliable in action, cost is low, the high speed sewing machine automatic needle-foot-lifting mechanism that production efficiency is high.
The technical scheme of the utility model high speed sewing machine automatic needle-foot-lifting mechanism is: comprise the electromagnet be arranged in head shell, the draw bar of electromagnet connects rear lever, rear lever cylinder lever connecting rod, pull bar connects presser feet system, described presser feet system comprises presser feet, presser feet there is depression bar, depression bar is installed pilot frame, it is characterized in that described pilot frame arranges connecting hole, connecting hole connects riser through hold-down screw, lever before riser is installed, front lever is shaped with pull bar steady pin, one end cylinder lever connecting rod steady pin of pull bar, axial screw installed by described rear lever, the other end of pull bar connects axial screw.
High speed sewing machine automatic needle-foot-lifting mechanism of the present utility model, main feature arranges connecting hole on described pilot frame, connecting hole connects riser through hold-down screw, lever before riser is installed, during work, the draw bar of electromagnet drives rear lever, rear lever pulls pull bar, pull bar pulls front lever again, by front lever drives pilot frame and depression bar, presser feet is lifted or depresses, compared with the prior art, after having had front lever, the pull bar actuation that electromagnet is driven is more stable, presser feet lifts or depresses reliably, avoid fault, enhance productivity.
High speed sewing machine automatic needle-foot-lifting mechanism of the present utility model, pressure guide hole is shaped with in described pilot frame, pilot bar is installed in pressure guide hole, pressure spring installed by pilot bar, and fixed by pressure regulating screw and look nut, regulated by the pressure of pressure spring to presser feet, make presser feet compress cloth.Be shaped with waist-shaped hole in described front lever, lever threaded before installing in waist-shaped hole, front lever threaded installs loose ends top board, easy for installation.The middle part presser foot lifter push rod of described rear lever, presser foot lifter push rod passes the housing of head, after electromagnet breaks down, can pull with hand presser foot lifter push rod, thus after driving, lever and pull bar pull presser feet.
Accompanying drawing explanation
Fig. 1 is the utility model high speed sewing machine automatic needle-foot-lifting mechanism exploded perspective view;
Fig. 2 is the utility model high speed sewing machine automatic needle-foot-lifting Mechanism Combination schematic diagram.
Detailed description of the invention
The utility model relates to a kind of high speed sewing machine automatic needle-foot-lifting mechanism, as Fig. 1, shown in Fig. 2, comprise the electromagnet 1 be arranged in head shell, the draw bar 2 of electromagnet connects rear lever 3, rear lever cylinder lever connecting rod 4, pull bar connects presser feet system, described presser feet system comprises presser feet 5, presser feet there is depression bar 6, depression bar is installed pilot frame 7, described pilot frame 7 arranges connecting hole 8, connecting hole connects riser 10 through hold-down screw 9, lever 11 before riser is installed, front lever is shaped with pull bar steady pin 12, one end cylinder lever connecting rod steady pin 12 of pull bar 4, axial screw 13 installed by described rear lever 3, the other end of pull bar 4 connects axial screw 13.The main feature of this programme arranges connecting hole 8 on described pilot frame 7, connecting hole connects riser 10 through hold-down screw 9, lever 11 before riser is installed, during work, the draw bar 2 of electromagnet 1 drives rear lever 3, rear lever 3 pulls pull bar 4, pull bar 4 pulls front lever 11 again, drives pilot frame 7 and depression bar 6, lift presser feet 5 or depress by front lever 11, compared with the prior art, after having had front lever, the pull bar actuation that electromagnet is driven is more stable, and presser feet lifts or depress reliably, avoid fault, enhance productivity.Be shaped with pressure guide hole 15 in described pilot frame 7, pilot bar 16 is installed in pressure guide hole, pilot bar is installed pressure spring 17, and fixed by pressure regulating screw 18 and look nut 19, regulated by the pressure of pressure spring to presser feet, make presser feet compress cloth.Be shaped with waist-shaped hole 20 in described front lever 11, lever threaded 21 before installing in waist-shaped hole, front lever threaded installs loose ends top board 22, easy for installation.The middle part presser foot lifter push rod 23 of described rear lever 3, presser foot lifter push rod passes the housing of head, after electromagnet breaks down, can pull with hand presser foot lifter push rod, thus after driving, lever and pull bar pull presser feet.
