Abstract
The utility model discloses a lace elasticity device for a sewing machine, which comprises a sewing machine control chip, a lace elasticity shaft and a sewing machine body, wherein a lace shaft fixing device, a transmission device and a lace elasticity rod are arranged on the lace elasticity shaft; the lace elasticity shaft is fixed on the sewing machine body through the lace shaft fixing device; and a driving motor is arranged at the tail end of the lace elasticity shaft. The lace elasticity device for the sewing machine, provided by the utility model, uses a stepper motor to replace transmission of an existing lace elasticity device with a connection rod of a sewing machine spindle, so that a transmission effect is improved; and an accurate device control effect through controlling the stepper motor by the chip is achieved, so that production efficiency and production quality are improved.
Description
Technical field
The utility model belongs to the Sewing machines field, particularly a kind of Sewing machines lace take-up.
Background technology
Lace take-up at Sewing machines is welcome by the user, the lace take-up of Sewing machines comprises lace degree of tightness axle on the market now, Sewing machines power connecting rod, the lace take-up of machine spindle and lace degree of tightness axle, wherein, lace degree of tightness axle is to connect machine spindle by Sewing machines power connecting rod, rotarily drive Sewing machines power connecting rod by machine spindle, and then drive lace degree of tightness axle carries out work, such equipment, because its mechanical connection, make Sewing machines noise when work very large, its dismounting is inconvenient, because its action and machine spindle synchronized movement are controlled inconvenience when making its work, cause easily poor product quality simultaneously, even directly cause the shortcomings such as product rejection, and in the former technology, the impeller set structure in its syndeton, this structure need to be added lubricant when work, caused inconvenience, its structure assembling is complicated simultaneously, efficient is low and very easily wear and tear and cause the shortcomings such as the life-span is short.
The utility model content
The purpose of this utility model provides and a kind ofly can guarantee the converted products quality, and cost is low, easy to operate Sewing machines lace take-up.
The purpose of this utility model is achieved through the following technical solutions:
A kind of Sewing machines lace take-up, comprise Sewing machines control chip, lace degree of tightness axle and sewing machine main body, be provided with lace shaft fixing device, transmission device and lace degree of tightness bar on the described lace degree of tightness axle, be fixed on the sewing machine main body by the lace shaft fixing device on the described lace degree of tightness axle, it is characterized in that described lace degree of tightness shaft end is provided with a drive motors.
In above-mentioned Sewing machines lace take-up, be provided with shaft coupling and motor mounting plate on the described lace degree of tightness axle, described shaft coupling is connected with lace degree of tightness axle, and described motor mounting plate is fixedly connected on the shaft coupling, and described motor is fixed on the motor mounting plate.
In above-mentioned Sewing machines lace take-up, described drive motors is stepper motor.
In above-mentioned Sewing machines lace take-up, described stepper motor is fixed on the sewing machine main body by fixed bar
In above-mentioned Sewing machines lace take-up, described stepper motor is connected with the Sewing machines control chip, directly controls motor by the Sewing machines control chip.
Compared with prior art, a kind of Sewing machines lace take-up of the present utility model utilizes stepper motor to replace in the former lace take-up and the connecting rod transmission of machine spindle, improved like this its transmission effect, reach accurately by the chip controls stepper motor simultaneously its device is controlled effect, improved its production efficiency and the quality of production.
Description of drawings:
Fig. 1 is the schematic diagram of the utility model Sewing machines lace take-up.Mark note among the figure: 100-lace degree of tightness axle 200-shaft coupling 300-motor mounting plate 400-stepper motor 500-motor fixed bar 600-sewing machine main body
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.
With reference to figure 1, Fig. 2: a kind of Sewing machines lace take-up, comprise Sewing machines control chip, lace degree of tightness axle 100 and sewing machine main body 600, be provided with lace shaft fixing device, transmission device and lace degree of tightness bar on the lace degree of tightness axle 100, be fixed on the sewing machine main body 600 by the lace shaft fixing device on the lace degree of tightness axle 100, wherein, lace degree of tightness axle 100 ends are provided with a stepper motor 400.
Wherein, stepper motor 400 is installed on the motor mounting plate 300, its motor mounting plate 300 is fixedly connected on the sewing machine main body 600 by fixed bar 500, its stepper motor 400 is by the work of chip (not marking among the figure) control step motor 400, drive shaft coupling 200 by stepper motor 400 and drive lace degree of tightness axle 100, its lace degree of tightness axle 100 is fixed on the sewing machine main body 600 by the lace shaft fixing device, rotarily drives 100 operations of lace degree of tightness axle at stepper motor 400 and comes and then drive lace degree of tightness bar to carry out work.
The above only is the utility model preferred embodiment; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
