Abstract
The utility model relates to an electronic control apparatus for the stitch length of a sewing machine. An executing motor, a screw rod, a positioning track and a sensor are arranged on a bracket body. The position of an oscillating arm of a connecting shaft is transferred to the sensor through a transforming mechanical structure. A shaft of the executing motor is mechanically connected with the screw rod, and a screw nut in a stop block of the oscillating arm is connected with the screw rod in a slide fit way. One side of the stop block of the oscillating arm is connected with the positioning track in a slide fit way. An electronic controller is electrically connected with the sensor through a position signal connecting line, and simultaneously, the electronic controller is electrically connected with the executing motor through a control connecting line. The stop surface of the oscillating arm is in contact with the oscillating arm of the connecting shaft in a spacing way. After the signals of the required stitch length are inputted by a key of the electronic controller, the signals are converted into digits by the electronic controller and the digits and the patterns of the required stitch length are displayed by a display screen. Simultaneously, the electronic controller causes the executing motor to be rotated by the control connecting line and the rotation of the executing motor drives the screw rod to rotate. The stop block of the oscillating arm sheathed on the screw rod can move upwards or downwards, the position of the oscillating arm of the connecting shaft which is in contact with the stop block of the oscillating arm in a spacing way is changed simultaneously, thereby, the stitch length is changed. The current position of the oscillating arm of the connecting shaft is transferred to the sensor through the mechanical transformation by a linking mechanism, is converted into the electrical signals of the current position by the sensor and is conveyed to.
Description
Technical field
The utility model relates to a kind of device of Electronic Control sewing device needle gage.
Background technology
At present, control needle gage length in the sewing device machine, be that connecting shaft swing arm position by pay-off is determined, the variation of this position, be by manual adjustment knob or regulating handle, realize the connecting shaft swing arm position of drivening rod device change pay-off, it is a kind of mapping mode that relies on manual adjustment, it exists control needle gage length location ambiguity, error is big, observation is inconvenient, the connecting shaft swing arm position change that influenced by mechanical shock and make, and make needle gage length influence of change to product quality.
Summary of the invention
In order to overcome existing needle gage length location ambiguity, deficiency that error is big, the utility model provides a kind of device of Electronic Control sewing device needle gage length, this device can change above-mentioned shortcoming, simultaneously directly show needle gage length and figure by display screen, it has easy to operate, working stability, advantage such as directly perceived.
The technical scheme that its technical problem that solves the utility model adopts (1) is: actuating motor is installed on stake body, screw mandrel, positioning track, the axle and the screw mandrel mechanical connection of actuating motor, screw in the swing arm block and screw mandrel sliding connection, swing arm block one side and positioning track sliding connection, electronic controller is electrically connected with actuating motor by the control connection line, the block face of swing arm block contacts with the connecting shaft swing arm is spacing, after importing desired needle gage signal by the button of electronic controller, electronic controller converts thereof into numeral and demonstrates desired needle gage numeral and pattern by display screen, electronic controller rotates actuating motor by the control connection line simultaneously, the rotation of actuating motor has driven the rotation of screw mandrel, the swing arm block that is sleeved on the screw mandrel just can move up or down, make with the spacing connecting shaft swing arm position that contacts of swing arm block and change simultaneously, thereby needle gage length is changed, when needle gage length arrives desired value, electronic controller just stops operating actuating motor by the control connection line, at this moment it is constant that connecting shaft swing arm rests on current location, thereby make sewing device according to electronic controller the needle gage length on shown carry out continuous operation, reached the purpose of Electronic Control sewing device needle gage length.
The technical scheme that its technical problem that solves the utility model adopts (2) is: actuating motor is installed on stake body, screw mandrel, positioning track, sensor, connecting shaft swing arm position is delivered to sensor by mechanical structure, the axle and the screw mandrel mechanical connection of actuating motor, screw in the swing arm block and screw mandrel sliding connection, swing arm block one side and positioning track sliding connection, electronic controller is connected with sensor electrical by the position signalling connecting line, electronic controller is electrically connected with actuating motor by the control connection line simultaneously, the block face of swing arm block contacts with the connecting shaft swing arm is spacing, after importing desired needle gage signal by the button of electronic controller, electronic controller converts thereof into numeral and demonstrates desired needle gage numeral and pattern by display screen, electronic controller rotates actuating motor by the control connection line simultaneously, the rotation of actuating motor has driven the rotation of screw mandrel, the swing arm block that is sleeved on the screw mandrel just can move up or down, make with the spacing connecting shaft swing arm position that contacts of swing arm block and change simultaneously, thereby needle gage length is changed, connecting shaft swing arm current location is by mechanical conversion, be delivered to sensor through interlinked mechanism, convert the current location signal of telecommunication to through sensor, be sent to electronic controller by the position signalling connecting line, when the signal of telecommunication of sensor acquisition arrives desired value, electronic controller just stops operating actuating motor by the control connection line, at this moment it is constant that connecting shaft swing arm rests on current location, thereby make sewing device according to electronic controller the needle gage length on shown carry out continuous operation, reached the purpose of Electronic Control sewing device needle gage length.
