Description

Sewing-machine foot hoisting mechanism
Technical field
The utility model relates to sewing machine technique, specifically a kind of sewing-machine foot hoisting mechanism.
Background technology
Automatic needle-foot-lifting mechanism is all have employed in industrial sewing machine, to alleviate the labour intensity of operating personnel, raise labour efficiency, existing automatic needle-foot-lifting mechanism is generally driven by electromagnet, if Chinese patent notification number is that CN203159869U discloses a kind of built-in automatic needle-foot-lifting mechanism for Sewing machines, comprise with lower component: casing, described casing comprises a uprights, is provided with a cavity in described uprights; Linear actuator is fixedly mounted in described cavity, described linear actuator comprises one can the draw bar of straight reciprocating motion, after having one, the rear end of lever is connected with the end of draw bar, the front end of rear lever comprises two pin-and-holes, wherein pin-and-hole is rotatably connected on casing by bearing pin before first, before rear lever rear end to first, the distance of pin-and-hole is greater than the distance of pin-and-hole before pin-and-hole to first before second, front lever comprises three pin-and-holes, and the first pin-and-hole is rotatably connected on casing by bearing pin; Second pin-and-hole and presser feet lifter plate are hinged; Before having second of the rear end of a pull bar and rear lever, pin-and-hole is hinged, and the front end of pull bar and the 3rd pin-and-hole of front lever are hinged; Presser bar lifting mechanisms is arranged enclosure interior by this mechanism, is amplified the active force of linear actuator by lever, and plays commutation effect, and make structure compacter, structure is more reasonable; But this automatic presser bar lifting mechanisms is once break down, and Sewing machines just cannot normally work, and makes troubles to production, its reliability need to improve; In addition because the draw bar of linear actuator and rear lever are hinged, rear lever rear end movement locus is camber line, and the movement locus of linear actuator is straight line, therefore exports when draw bar and rear lever in driving process and be affected, sometimes also there will be distortion or stuck phenomenon.
Utility model content
The purpose of this utility model is to provide a kind of sewing-machine foot hoisting mechanism, linear actuator is controlled push rod end and fore-set is set, in the rear end of rear lever, the position of corresponding fore-set arranges roller screw, roller screw is socketed plastics roller, adopt fore-set to coordinate with plastics roller and ensure the smooth and easy and stable of presser bar lifting mechanisms work, and play the effect of noise reduction, the utility model is equipped with artificial riding simultaneously and controls push rod in the middle of rear lever, once linear actuator fault, Artificial Control can be adopted, both do not interfere with each other, the utility model has rational in infrastructure, the feature of good reliability.
For achieving the above object by the following technical solutions:
A kind of sewing-machine foot hoisting mechanism, lever after linear actuator, pull bar and L-type, after pull bar and L-type, lever front end is hinged, after L-type, its intermediate part is hinged on Sewing machines housing, it is characterized in that: described linear actuator controls push rod is provided with fore-set, fore-set is fixed on by screw and rubber sheet gasket the top that linear actuator controls push rod, and the diameter of fore-set is greater than the diameter controlling push rod; After described L-type, the position of the corresponding fore-set of lever rear end arranges roller screw, roller screw is socketed plastics roller, also hinge hole is offered between its intermediate part articulated section and rear end after described L-type, have the artificial foot-operated push rod upper end that controls to be movably connected in hinge hole, the artificial foot-operated push rod lower end that controls is connected with artificial foot pedal apparatus.
The top that the utility model controls push rod at linear actuator arranges fore-set, and the area of the fore-set end face strengthened, fore-set and plastics roller fit system, can Free-rolling when plastics roller can be made to contact with fore-set end face, linear actuator Power output can be made full use of, and there will not be distortion and stuck phenomenon, sewing-machine foot promotes more smooth and easy; The utility model is also provided with artificial riding and controls push rod after L-type between its intermediate part articulated section and rear end in addition, when electronic linear actuator cannot normally work, artificial foot-operated mode can also be adopted to control the lifting of presser feet, ensure the ground work of sewing function normal reliable, the utility model has feature that is rational in infrastructure, good reliability.
Accompanying drawing explanation
Fig. 1 is that the utility model drives the structural representation of pressure foot lifting by footstep mechanism.
Detailed description of the invention
As shown in Figure 1, a kind of sewing-machine foot hoisting mechanism, lever 3 after linear actuator 1, pull bar 2 and L-type, after pull bar 2 and L-type, lever 3 front end is hinged, be hinged in the middle part of lever 3 on Sewing machines housing after L-type, it is characterized in that: described linear actuator 1 controls push rod 11 is provided with fore-set 5, fore-set 5 is fixed on by screw 6 and rubber sheet gasket 7 top that linear actuator controls push rod 11, and the diameter of fore-set 5 is greater than the diameter controlling push rod 11; After described L-type, the position of the corresponding fore-set 5 in lever 3 rear end arranges roller screw 8, roller screw 8 is socketed plastics roller 9, hinge hole 10 is also offered between articulated section and rear end in the middle part of lever 3 after described L-type, have artificial foot-operated push rod 12 upper end that controls to be movably connected in hinge hole, artificial foot-operated push rod 12 lower end that controls is connected with artificial foot pedal apparatus.
The top that the utility model controls push rod at linear actuator arranges fore-set, and the area of the fore-set end face strengthened, when fore-set coordinates with plastics roller, plastics roller can at fore-set end face Free-rolling, can make full use of linear actuator Power output like this, and there will not be distortion and stuck phenomenon, sewing-machine foot promotes more smooth and easy; The utility model is also provided with artificial riding and controls push rod after L-type between its intermediate part articulated section and rear end in addition, when electronic linear actuator cannot normally work, artificial foot-operated mode can also be adopted to control the lifting of presser feet, ensure the ground work of sewing function normal reliable, the utility model has feature that is rational in infrastructure, good reliability.
