Technical field
The utility model relates to a kind of Sewing machines, especially a kind of sewing machine cloth feeding governor motion.
Background technology
At present, the multi-purpose sewing machine used towards family circulated on market, normally comprise driving shaft on cloth feeding structure, cam and cloth conveying teeth, when eedle penetrates sewing, feed dog descends, when eedle exits sewing, feed dog rises and travels forward, sewing is driven forward, control moving up and down of cloth conveying teeth by cam, but this structural joint is made the length of the common needle tracking of cloth come and is all fixed, function singleness, can not regulate, when making different stitch lengths, needs just need different Sewing machiness to realize, increased production cost, reduced operating efficiency, use very inconvenience.
The utility model content
The utility model will solve the problem that above-mentioned prior art exists, and a kind of sewing machine cloth feeding governor motion is provided, rational in infrastructure, length easy to use, as can to regulate as required needle tracking, diverse in function, can reduce production costs, can increase work efficiency, meet people's demand.
The utility model solves the technical scheme that its technical problem adopts: this sewing machine cloth feeding governor motion, comprise driving shaft, the output of driving shaft is provided with cloth conveying teeth and cloth conveying teeth props up platform, cloth conveying teeth is arranged on cloth conveying teeth and props up on platform, the end that cloth conveying teeth props up platform is connected with upper and lower wrist, be connected with the cam up and down be fixed on driving shaft on upper and lower wrist, the other end that cloth conveying teeth props up platform is connected with the work feed wrist, work feed wrist and cloth conveying teeth prop up between the end of platform and are connected with two fork arms, the bottom of two fork arms is connected with the horizontal feed eccentric be fixed on driving shaft, one end of two fork arms connects the work feed wrist and cloth conveying teeth props up platform, the other end of two fork arms is connected with the work feed chute, be connected with stepper motor on the work feed chute, stepper motor is arranged on driving shaft.After arranging like this, rational in infrastructure, during use, horizontal feed eccentric, two fork arms, the work feed chute has formed cam rocker arm mechanism, rotatablely moving of driving shaft is transformed to oscillating motion, and prop up platform by cloth conveying teeth oscillating motion is passed to cloth conveying teeth, form horizontal work feed motion, simultaneously, being fixed on cam up and down on driving shaft promotes upper and lower wrist and swings in the vertical direction, and prop up platform by cloth conveying teeth and drive cloth conveying teeth and realize that with horizontal work feed sports coupling work feed moves, stepper motor drives the work feed runner movement, the angle of adjusting like this work feed chute can obtain the needle tracking of different length, so just do not need many Sewing machiness to make the needle tracking of different length, can reduce production costs, can increase work efficiency, result of use is good.
On stepper motor, be connected with for sending the master controller of trace data.After arranging like this, master controller can send to stepper motor to the stitching position data be stored in master controller, and stepper motor drives the work feed runner movement to obtain the stitch length needed according to the stitching position data.
On driving shaft, be connected with for driving the main shaft of driving shaft motion.After arranging like this, main shaft is for driving the driving shaft motion.
The effect that the utility model is useful is: sewing machine cloth feeding governor motion of the present utility model, rational in infrastructure, easy to use, horizontal feed eccentric, two fork arms, work feed chute have formed cam rocker arm mechanism, and stepper motor stitch length as required drives the work feed runner movement to form the stitch length needed, and just can realize like this sewing of different needle trackings on the separate unit Sewing machines, can reduce production costs, can increase work efficiency, result of use is good, is beneficial to popularization.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment;
