Technical field:
The utility model is the device that is used to control the work feed gear on a kind of tack keyhole, belongs to sewing machine technique, particularly a kind of work feed gear automaton of straight buttonholing machine.
Background technology
Straight buttonholing machine is a kind of special mechanical in the Sewing machines, it is the cloth-pressing device that utilizes the feed mechanism drive machine of work feed gear, thereby drive the cloth motion, use the stitching of Sewing machines to form principle again, reach the purpose that on cloth, forms various keyhole stitch seam.At present, straight buttonholing machine is locked at the moment at cloth, often runs into because mechanical wear generation parking spot is forbidden situation, thereby causes the keyhole pattern in disorder, not attractive in appearance, even damage, and causes the waste of artificial and dress material; Moreover, produce very big noise because the feed mechanism of traditional work feed gear is by mechanical braking, bring very major injury to the operator.
Summary of the invention
The purpose of this utility model is in order to overcome the defective that existing work feed feed gearing mechanism parking spot is inaccurate, noise is big, invent a kind of work feed gear automaton of straight buttonholing machine, it can make lockstitch button holder when work, the accurate off-position of work feed gear, keyhole pattern neat appearance, and noise is low, long service life, easy to maintenance, high efficiency.
The purpose of this utility model realizes as follows: the work feed gear automaton of described straight buttonholing machine, comprise servomotor, servomotor is provided with axle, it is characterized in that: go up axle and be provided with worm screw, worm screw is connected with driving gear by worm gear, driving gear and driven gear engagement, driven gear is provided with vertical shaft, vertical shaft is provided with travelling gear, travelling gear and work feed gears engaged, the work feed gear is provided with cam path, and an end of feeding arm is located in the cam path, the other end of feeding arm is provided with the dial assembly, the dial assembly is connected with stock support by the feeding connecting rod, and stock support is provided with delivery sheet and feeding arm, and delivery sheet is provided with bracket, bracket is connected with the feeding arm by cloth feed collet support, decide sensing chip and be located at the edge of work feed gear by screw, moving sensing chip is being decided on the sensing chip by adjustment screw is superimposed, and it is adjustable making the relative position of deciding sensing chip and moving sensing chip, the sensing chip next door is provided with the inductor support, and the inductor support is provided with inductor.
Good effect of the present utility model is as follows: can be by regulating before and after the adjustment screw owing to decide the superimposed position of sensing chip and moving sensing chip, make and to enter the time of low speed and the length of slowtime has corresponding change, thereby guaranteed in different keyhole length, the stability that keeps machine, to adapt to different requirement down time of different keyhole length, make the stitching neat appearance of keyhole, increase work efficiency.
