Abstract
The present invention relates to the needle gage regulating mechanisms and its working method of a kind of sewing machine, using a kind of sewing machine of the invention needle gage regulating mechanism metering needle away from when, the rotation of the second connecting lever is driven by driving device, second connecting lever drives rotation connecting lever rotation by fourth link, rotates the position that connecting lever drives third connecting rod movement and adjusts the first pin shaft；Because the position of the first pin shaft is adjusted, so the drive connection between first connecting rod and second connecting rod is just adjusted, in this way, the rotation amplitude for being transmitted to the first connecting lever and feed spool in universal connecting shaft rotation is just adjusted, therefore the needle gage of sewing machine is just adjusted.Rotation position locating for second connecting lever determines the position of the second pin shaft, to determine that universal connecting shaft is transmitted to the drive connection on feed spool, and then determines the size of needle gage.Therefore, the rotation position for adjusting the second connecting lever can adjust the needle gage of sewing machine.
Description
Technical field
The present invention relates to the needle gage regulating mechanisms and its working method of a kind of sewing machine.
Background technique
It is as shown in Figure 1 three step feeder of traditional roller sewing machine, traditional three step feeder of roller sewing machine is by upper roller
Feeding mechanism 2, bottom roller feeding mechanism 4,3 three parts of needle feeding mechanism composition, and the feeding mechanism of each section be all by
Stepper motor 1 independently carries out driving feeding；This feeding mechanism needs to use three stepper motors 1, in automatically controlled control, by electricity
The control carried out on software to stepper motor 1 is controlled, guarantees the harmony and synchronism of three stepper motors 1, in this way in feeding
When be just not in mistake on action sequence, in metering needle away from needing the cooperation of three stepper motors 1 could be complete
At.
Although three step feeder of roller sewing machine is upper more convenient in feeding adjusting, due to having used three stepping electricity
Machine causes the automatically controlled control requirement for stepper motor just very high, automatically controlled to need to control stepper motor and keep same in the feeding process
Step property and harmony.If will lead to stepper motor using inexpensive control program to be possible to will appear mistake in use
The phenomenon that step, causes existing a whole set of controller cost excessively high, control so control program uses complicated control program substantially at present
The cost of device processed is far longer than complete machine cost, is difficult in marketing application.
Summary of the invention
In view of the foregoing deficiencies of prior art, the purpose of the present invention is to provide a kind of needle gages of sewing machine to adjust machine
Structure and its working method can be conveniently adjusted the suture needle needle gage of sewing machine, and structure is simple, and cost is relatively low.
To achieve the above object, the present invention provides a kind of needle gage regulating mechanism of sewing machine, adopts the following technical scheme that one
The needle gage regulating mechanism of kind of sewing machine, including rack, universal connecting shaft and feed spool for driving the needle sports of sewing machine,
Be connected with eccentric cam on universal connecting shaft, the first connecting lever be connected on feed spool, from the first connecting lever between eccentric cam according to
Secondary to be hinged with first connecting rod and second connecting rod, one end of first connecting rod and the first connecting lever are hinged, and the other end of first connecting rod passes through
First pin shaft is hinged with second connecting rod, and second connecting rod is hinged on eccentric cam；The universal connecting shaft rotates and drives feeding
Axis rotation, to drive the needle sports of sewing machine；
It further include the first connecting shaft and the rotation connecting lever being hinged in the first connecting shaft, rotation connecting lever includes the first arm and the
Two arms；One end of first arm and third connecting rod is hinged by the second pin shaft, and the other end of third connecting rod is hinged on first pin
On axis；One end of second arm and fourth link is hinged, and the other end of fourth link is hinged on the second connecting lever, and the second connecting lever is by driving
Dynamic device drives and rotates.
Preferably, the eccentric cam is cylindrical, and the second connecting rod covers on the external cylindrical surface of eccentric cam.
Preferably, first connecting shaft is rotatably connected in rack.
Preferably, first arm and the second arm are separately fixed at the both ends of the first connecting shaft.
Preferably, the driving device is stepper motor, and stepper motor is connect with control device.
Preferably, the universal connecting shaft, feed spool, the first connecting shaft axial location immobilize.
Preferably, the driving device is fixed on the rack.
Correspondingly with the needle gage regulating mechanism of sewing machine of the invention a kind of, the present invention also provides a kind of needle gages of sewing machine
The working method of regulating mechanism utilizes the needle gage tune of sewing machine described in above-mentioned technical proposal or its any preferred technical solution
It saves mechanism and carries out operation, including following work step:
1) metering needle away from, comprising:
