The zigzag sewing mechanism of the sewing machine has the advantages that the structure is simple, using is convenient, the sector gear enables rotational motion of the stepping motor to be converted into reciprocating motion which is transmitted to the needle bar support through the inducing plate, the needle bar support drives the needle bar and the machine needle to swing left and right and is in movement coupling with the vertical direction of the machine needle, zigzag sewing of stitches can be achieved, the function is complete, production cost can be lowered, the using effect is good, and popularization is facilitated.
Description
Technical field
The utility model relates to a kind of Sewing machines, the tortuous seam of especially a kind of Sewing machines mechanism.
Background technology
At present, the multi-purpose sewing machine used towards family circulated on market, structurally generally include main motor, main shaft, cam etc., its bent FELL STITCH forms mechanism and is comprised of a series of cams, when needs are made certain stitching pattern, rotate the stitching pattern and select button, corresponding cam is connected with main shaft, when making the stitching pattern, main motor driving main shaft rotation, cam rotates thereupon, the concavo-convex trail change of cam is changed to realize by the eedle oscillating quantity of eedle swing mechanism, change the concavo-convex trail change of cam into the stitching pattern thus, due to the corresponding a kind of stitching pattern of each cam, and the Sewing machines inner space is limited, too much cam can not be installed, within the stitching pattern that can make like this just is limited at some, at most also can only reach tens kinds of stitching patterns, and cam need to adopt complicated stitching clutch with being connected of main shaft, therefore need higher technology and more labour to assemble Sewing machines, this has just increased the production cost of Sewing machines.
The utility model content
The utility model will solve the problem that above-mentioned prior art exists, and the tortuous seam of a kind of Sewing machines mechanism is provided, rational in infrastructure, easy to use, is convenient to assembling and debugging, and the stitching pattern kind that can make is many, multiple functional, has met people's demand.
The utility model solves the technical scheme that its technical problem adopts: the tortuous seam of this Sewing machines mechanism, comprise needle bar bracket, the lower end of needle bar bracket is fixed with shank, the lower end of shank is connected with eedle, and the top of shank is provided with the ductor be fixed on needle bar bracket, an end connecting needle shaft bar of ductor, the other end of ductor is connected with sector gear, be engaged with the motor-driven gear on sector gear, on the motor-driven gear, be connected with stepper motor, stepper motor is fixed on needle bar bracket.After arranging like this, rational in infrastructure, easy to use, during use, stepper motor drives the electric transmission gear movement, the motion of electric transmission gear driven sector gear, sector gear is transformed to reciprocating motion by rotatablely moving of stepper motor and passes to needle bar bracket by ductor, needle bar bracket drives shank and eedle swings, and with the coupling of eedle movement in vertical direction, realizes bent FELL STITCH.
On stepper motor, be connected with for sending the master controller of trace data.After arranging like this, different types of stitching can be stored in master controller, master controller sends to stepper motor for stepper motor can be rotated according to required angle and direction the trace data of needs, owing in master controller, can storing a large amount of trace datas, so just can make a large amount of stitching pattern kinds, increased considerably the stitching pattern of Sewing machines, multiple functional, result of use is good.
Be connected with the main shaft for the motion of driving needle shaft bar on needle bar bracket.After arranging like this, main shaft is for the motion of driving needle shaft bar.
Ductor is fixed on needle bar bracket by bolt one.After arranging like this, adopt the fixing ductor of bolt one to be convenient to installation and maintenance.
Sector gear is fixed on needle bar bracket by bolt two.After arranging like this, adopt the fixing sector gear of bolt two to be convenient to installation and maintenance.
The effect that the utility model is useful is: the tortuous seam of Sewing machines of the present utility model mechanism, rational in infrastructure, easy to use, sector gear is transformed to reciprocating motion by rotatablely moving of stepper motor and passes to needle bar bracket by ductor, needle bar bracket drives shank and eedle swings, with the eedle movement in vertical direction, be coupled, realize bent FELL STITCH, different types of stitching can be stored in master controller, master controller sends to stepper motor for stepper motor can be rotated according to required angle and direction the trace data of needs, owing in master controller, can storing a large amount of trace datas, so just can make a large amount of stitching pattern kinds, increased considerably the stitching pattern of Sewing machines, multiple functional, can reduce production costs, result of use is good, be beneficial to popularization.
