Description
Technical field
It the utility model is related to a kind of accessaries of sewing machine, and in particular to a kind of middle presser foot drive of sewing machine.
Background technology
Middle presser feet is mainly used in some special sewing machine fields, such as pattern sewing machine, bar tacking machine, template machine etc., is a kind of
Very important moving component on sewing machine.Presser feet is made up and down during existing middle presser foot device drives generally by mechanical cam
Motion.This mechanism is relative complex, and adjustment is cumbersome, and high and low position is difficult to control.
Also a kind of middle presser foot device is to drive presser feet to move up and down by motor, but needs crank, connecting rod etc. zero
For part as transmission mechanism, structure is relative complex, and is easily failed during high-speed motion or occur mechanical breakdown.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of middle presser foot drive of sewing machine, and it can letter
Change structure.
In order to solve the above technical problems, the technical solution of the middle presser foot drive of the utility model sewing machine is：
Including stepper motor 2, shaft coupling 3, screw rod 4, nut 5, depression bar joint 6, connecting rod 7, depression bar 9, the electricity of stepper motor 2
One end that arbor 21 passes through the connecting screw 4 of shaft coupling 3；Nut 5 is provided with screw rod 4；Nut 5 is fixedly connected with the upper end of connecting rod 7,
The lower end of connecting rod 7 is fixedly connected with depression bar joint 6；Depression bar joint 6 is fixedly connected with the upper end of depression bar 9, is pressed in the lower end connection of depression bar 9
Pin.
The stepper motor 2 is fixedly installed on the top of head 1.
Depression bar set 8 is arranged with the depression bar 9.
What the utility model can reach has the technical effect that：
The principle that screw rod moves along a straight line is used in the drive mechanism of middle presser feet by the utility model, and stepper motor can pass through
Controller realizes accurate control, the height that presser feet moves up and down in convenient adjustment.
The utility model structure is simplified, easy for installation, and control is simple, and precision is accurate, can accurately be controlled in sewing process
The high and low position of middle presser feet, and control accuracy is higher, so as to adapt to the sewing of different-thickness sewing.

Nut 5 is provided with screw rod 4；Nut 5 is fixedly connected with the upper end of connecting rod 7, and the lower end of connecting rod 7 is fixedly connected with depression bar and connect
First 6；
Depression bar joint 6 is fixedly connected with the upper end of depression bar 9, and depression bar set 8 is arranged with depression bar 9；Pressed in the lower end connection of depression bar 9
Pin.
Operation principle of the present utility model is as follows：
The motor shaft 21 of stepper motor 2 is reciprocating, drives nut 5 reciprocating by screw rod 4, so as to pass through pressure
Presser feet is realized and pumped during bar 9 drives；
The up and down motion amount of the motor shaft 21 of stepper motor 2 is adjusted by controller, you can the fortune up and down of presser feet in adjustment
Momentum, without adjusting mechanical location.
Although embodiment of the present utility model is hereinbefore described in detail, come for those skilled in the art
Say it is readily apparent that various modifications and variations can be carried out to these embodiments.However, it is understood that this modification and change
Change is belonged within the scope of the utility model and spirit described in claims.Moreover, described herein practicality is new
Type can have other embodiments, and can be practiced or carried out in several ways.
