Detailed Description
The drawings are for illustrative purposes only and are not to be construed as limiting the patent; for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted. The positional relationships depicted in the drawings are for illustrative purposes only and are not to be construed as limiting the present patent.
Referring to fig. 1 to 4, a structure diagram of the needle plate adjusting driving assembly of the present invention includes: drive seat, step motor, faller slide bar, lead screw and lead screw connecting seat, step motor install on the drive seat, two lead screws are horizontal symmetry and install on the drive seat, step motor passes through synchronizing wheel and brings the drive lead screw in step and rotates, two lead screw connecting seats are installed respectively on the lead screw and are made along the lead screw and come and go linear displacement, the faller slide bar passes through the regulating block and installs on the lead screw connecting seat.
According to the scheme, the driving seat is provided with the sensor fixing seat, the sensor fixing seat is located on one side of the screw rod connecting seat, the U-shaped zero position sensor and the U-shaped displacement sensor are arranged on the sensor fixing seat, the sensing piece is arranged on the screw rod connecting seat, and the sensing piece moves back and forth between the U-shaped zero position sensor and the U-shaped displacement sensor. Needle board slide bar one end fix at the regulating block, the needle board slide bar other end is equipped with three and keeps off the adjustment tank, three keep off the adjustment tank inboard and be equipped with inside arch and form high section, middle section and the three slope of low section, chew a mouthful distance through high section, middle section and the three slope of low section adjustment needle board.
Example 1
According to the scheme, the driving seat is provided with the two-step motor, one end of each of the two screw rods is connected with the synchronizing wheel, and the two-step motor controls the synchronizing wheel to rotate through the two synchronous belts separately. Each stepping motor can independently control a screw rod to rotate, so that the horizontal displacement of the sliding rod of the needle plate is separately controlled, and the front needle plate and the rear needle plate are independently controlled.
