Specific embodiment:
With specific embodiment, the invention will be further described below, referring to Fig. 1-4:
A kind of sewing machine, including casing 1, are provided with governor seat 2 on casing 1, are provided on energy on governor seat 2
The pull rod 3 of lower slider, the both ends of pull rod 3 are stretched out except governor seat 2, are arranged on the pull rod 3 being located above governor seat 2
There is upper limit 4, is provided with lower limit 5 on the pull rod 3 being located at below governor seat 2, upper limit 4 of the present invention, lower limit
Position 5 is retaining ring or circlip etc..In addition, one of upper limit 4, lower limit 5 can also be the limit with 3 integrated formed structure of pull rod
The structure of position convex edge.Spring 6 is arranged with outside pull rod 3, one end of spring 6 is held out against on upper limit 4, and the other end, which is held out against, to be adjusted the speed
On device seat 2, it is provided with magnet 7 on pull rod 3, Hall is additionally provided on governor seat 2, the Hall is linear Hall 8.
The linear Hall 8 is oppositely arranged with magnet 7, and the linear Hall 8 is connect with controller.Pull rod 3 under the effect of external force on
Lower slider band moving magnet 7 moves up and down, to make that relative displacement occurs between linear Hall 8 and magnet 7, exports different voltage
Value, has the function that speed regulation.Magnet 7 of the invention is embedded on pull rod 3, is also possible to that mounting hole, magnet are arranged on pull rod 3
7 are fixed in mounting hole by glue.
Specifically, the linear Hall 8 is arranged on governor seat 2 by Hall support 9.
Its axis is provided with straight trough mouth 10 on pull rod 3 of the present invention, is provided with guide plate on governor seat 2
11, one end of guide plate 11 is arranged in straight trough mouth 10.During pull rod 3 is up and down, through guide plate 11 on pull rod 3
Straight mouth slot 10 in opposite move up and down, it is ensured that axial rotation does not occur for pull rod 3, and stable speed is kept to adjust, meanwhile, also have
There is guiding.
Further, it is provided in the lower limit 5 with 10 corresponding position of straight trough mouth and to pass through for one end of guide plate 11
Open slot, the guide plate 11 are installed on the baseplane of governor seat 2.
Certainly, guide plate 11 of the invention can also use zigzag configuration, and the part in straight trough mouth 10 is located on guide plate 11
Lower than the part on the baseplane for being fixed on governor seat 2, and be located at straight trough mouth 10 in part be fixed on governor seat 2
The distance between part on baseplane is greater than the difference of 3 high-low limit position of pull rod, guarantees between guide plate 11 and lower limit 5 not
Generate interference.
In order to facilitate the installation of, governor seat 2 of the present invention is L-shaped, and the vertical plate 12 of governor seat 2 is fixed on casing
On 1, pull rod 3 is arranged on level board 13.Corresponding Hall support 9 is also disposed on level board 13.
Governor seat 2 of the present invention is arranged on the side for installing controller on casing 1, and the governor seat 2 is drawn
In the chamber that bar 3, Hall 8, magnet 7 are located at the housing 14 of controller and casing 1 is formed, and control is stretched out in the lower end of the pull rod 3
Except the housing 14 of device processed, the Hall 8 is electrically connected with the circuit board 15 in controller.
Governor is incorporated into controller by the present invention, realize the integrated structure of complete machine, it is easy for assemble or unload, save at
This.
The working principle of the invention:
Pull rod 3 slides up and down under the effect of external force, and band moving magnet 7, which synchronizes, to be slided up and down.Pass through the upper limit 4 of pull rod 3
Compressed spring 6, the decrement of spring 6 is controlled by governor seat 2, so that magnet 7 be made to be slided in a certain range, is oriented to
The straight trough mouth 10 that is arranged on pull rod 3 is arranged in prevent pull rod 3 from being rotated in one end of plate 11, and lower limit 5 controls pull rod 3 and springs back
Position, Hall 8 is oppositely arranged with the magnet 7 on pull rod 3.
When no external force is on pull rod 3, pull rod 3 is in upper limit position, that is, under the action of spring 6, pull rod 3
On lower limit 5 be connected on governor seat 2, magnet 7 with respect to Hall 8 farther out, Hall 8 cannot sense magnet 7, not export
For voltage value signal to controller, controller does not issue signal instruction, motor stopping；
When having external force on pull rod 3, from upper limit position to lower limit position movement, (magnet 7 is driven in drawing to pull rod 3
Bar 3), at this point, spring 6 is compressed, pull rod 3 is moved down, and magnet 7 is moved closer to relative to the distance of Hall 8, and Hall 8 exports
Voltage value be gradually increased from zero, export linear increased voltage value to controller, controller control motor is ramped up,
After reaching upper limit site, magnet 7 and linear Hall 8 are apart from minimum, and magnet 7 and 8 relative position of linear Hall are kept constant at this time,
Linear Hall 8 exports greatest limit voltage value to controller, and motor reaches maximum speed, constant operation.
Above-described embodiment is only one of presently preferred embodiments of the present invention, and but not intended to limit the scope of the present invention, therefore:
The equivalence changes that all shape, structures under this invention, principle are done, should all be covered by within protection scope of the present invention.
