Specific embodiment
In the following, in conjunction with example, property feature and advantage is further described for the essence of the present invention, but the present invention not office
It is limited to listed embodiment.
Referring to shown in Fig. 1-4, a kind of overedger speed regulation device, including：
Magnetic block 7 is mounted on the pulling plate 2 for connecting with pull rod 6 by mounting blocks 3, which is located at 1 side of box body
And connect with box body by fixing axle 9, which can rotate with the lifting of the pull rod and around the fixing axle 9, thus band
The magnetic block 7 is moved to go up and down；
Circuit board 8 is located at 1 other side of box body, sets sensing device 81 on the circuit board；The sensing device can by with
Different location incudes and circuit board is made to export different driving signal on the magnetic block, is respectively used to motor rotation control, lift pressure
Foot control system；
Limit assembly, for the rotational angle limit to the pulling plate 2, including upper torque spring 5 and lower torque spring 4；
Bumping post 11, lower bumping post 12 are set in the box body, upper torque arm 42, the lower torque arm 41 of the lower torque spring 4 are located at described
Upper 11 top of bumping post and lower 12 lower section of bumping post；The upper torque arm of the upper torque spring is in contact with the interior upper edge of the box body, under
Torque arm connects with the mounting blocks 3.
In the present invention, the upper bumping post 11, lower bumping post 12 are respectively used to the upper torque arm 42 to lower torque spring 4, lower torque arm
41 are limited.
In the present invention, the circuit board 8 is integrated with the functional circuit module and auto lifting pressure of existing overedger governor
Foot functional circuit module may be implemented to control motor speed and export automatic needle-foot-lifting driving signal.
The sensing device 81 is Magnetic Induction switch.
Wherein, the pull rod 6 connects pedal 10, when which is depressed downwards, keeps pulling plate 2 clockwise by pull rod 6
Rotation, and when pedal is depressed upwards, pulling plate 2 can be made to rotate counterclockwise.
As shown in figure 3, the upper torque arm 42 of lower torque spring 4, lower torque arm 41 after being installed in box body 1 by upper bumping post 11,
Lower bumping post 12 struts, and upper torque arm 42 is limited by upper bumping post 11, and lower torque arm 41 is limited by lower bumping post 12.The lower torsion of upper torque spring 5
Arm is pressed at the card slot of mounting blocks 3.
When pulling plate 2 is in equilibrium state (standby mode), pulling plate is by self gravity (including the drawing being connected on pulling plate
Bar 6 and pedal 10) and the resultant force of elastic force of upper torque spring 5 be pressed in the lower torque arm 41 of lower torque spring 4, this torsion at present
The elastic force of spring 4 is greater than above-mentioned resultant force, so pulling plate 2 not can rotate.This upper torque arm 42 of torque spring 4 and magnetic block at present
Mounting blocks 3 are contactless, no interaction force.
And when stepping on pedal downwards, pulling plate 2 rotates clockwise, and the mounting blocks 3 and magnetic block 7 being mounted on pulling plate are together
It moves, after the sensing element 81 on circuit board 8 detects movement, shown in Figure 4, sensing element 81 detects magnetic block 7
When upper area 72, the driving voltage of motor can be changed by the upper area 72 of magnetic block 7, transmitting control signal is to control
Case, control cabinet make the motor driven of packet sewing machine, machine run, and pedal steps on that amplitude is bigger, and the driving voltage variation of motor is got over
Greatly, motor speed is faster.When foot is detached from pedal 10, the elastic force of the lower torque arm 41 of lower torque spring 4 makes pulling plate 2 set back.
During setting back, since upper torque spring 5 has downward elastic force, pulling plate 2 will not be moved upwards because of inertia to
Generate maloperation.
And when stepping on pedal 10 upwards, pulling plate 2 rotates counterclockwise, the mounting blocks 3 and magnetic block 7 one being mounted on pulling plate
Movement is played, after the sensing element 81 on circuit board 8 detects movement, shown in Figure 4, sensing element 81 detects magnetic block 7
Lower area 71 when, can export the driving signal of automatic needle-foot-lifting device under automatic needle-foot-lifting mode, realize auto lifting pressure
Foot device be actuated for automatic needle-foot-lifting or under non-automatic presser foot lifter mode manual presser foot lifter realization；Pulling plate 2 turns counterclockwise
When dynamic, it can be detached from the effect of the lower torque arm 41 of lower torque spring 4, by upper torque spring 5 and lower torque spring 4 during this
The effect of upper torque arm 42.After foot is detached from pedal 10, pulling plate 2 sets back.
It should be noted that, when sensing element 81 detects the central region 70 of magnetic block 7, being drawn at this time in the present invention
Plate is in standby, i.e., detection zero-bit state, i.e. pulling plate 2 are not moved up, also do not move downward, and motor is standby not to be rotated.
Wherein, in specific implementation, the spring column sleeve of the lower torque spring 4 is mounted in the formation fixed shaft hole 13 of the box body
Outside cylinder.
Wherein, in specific implementation, spring mounting post (peace of the spring column sleeve of the upper torque spring 5 in the box body
Dress column have screw hole) on and with gasket 51 and screw 52 in axial lock.
Wherein, in specific implementation, the fixing axle 9 be mounted in the fixed shaft hole 13 after in radially with jackscrew 91 (Gu
Dead axle hole 13 is radially provided with top wire hole) locking, and with circlip 92 in the outer side lock of the pulling plate 2.
Wherein, in specific implementation, the mounting blocks 3 of the magnetic block and the pulling plate 2 31 (pulling plate of mounting blocks fixing screws
1 is equipped with the mounting hole of mounting blocks fixing screws 31) it is fixed.
Specifically, mounting blocks fixing screws 31 are two.
Wherein, in specific implementation, the lower torque arm of the upper torque spring 5 is stuck in the card slot on the mounting blocks 3, is such as schemed
Shown in 2, the right side of the mounting blocks 3 has magnetic block mounting groove, and upper and lower side has card slot, is used for upper and lower torque spring
Torque arm be stuck in this and be connected with the mounting block.
Wherein, in specific implementation, the circuit board 8 is connected and fixed with the box body 1 by circuit board attachment screw 82.
Using the above structure due to overedger speed regulation device of the invention, thus the speed regulation device structure is simple, thus can
To accomplish smaller size, therefore the overedger speed regulation device can be mounted on the body of sewing machine by the box body.
The object of the invention is also to provide a kind of overedgers, including the overedger speed regulation device.
The present invention realizes when pulling plate rotates clockwise or counterclockwise by above scheme, utilizes the sense on circuit board
It answers device to make the different control signals of circuit board output and incuding from different location on the magnetic block, is respectively used to motor turn
Dynamic control, presser foot lifter control, realize and realize motor rotation control and the control of presser foot lifter using motor speed control device, and tie
