Detailed description of the invention
First, composition graphs 1 to Fig. 3 illustrates the presser foot of embroidery machine height automatic regulating apparatus in the present invention, a driving shaft 151 is horizontally disposed with in presser feet 165 side, presser feet 165 drives adjustment height by a presser feet drive block 163, the hinged presser feet drive link 169 of described presser feet drive block 163, described presser feet drive link 169 is hinged with one end of presser feet lever 162, the other end of described presser feet lever 162 is driven by eccentric cam 157, described eccentric cam 157 is installed on a presser feet and drives on hinge pin 155, described driving shaft 151 is driven by motor 156, described driving shaft 151 drives presser feet to drive hinge pin to rotate by cam link mechanism.
Described cam link mechanism comprises and is fixed on the hinged first connecting rod 152 of driving cam 168 on driving shaft and one end and driving cam, the other end of first connecting rod and one end of second connecting rod 153 hinged, the other end of second connecting rod 153 and presser feet drive hinge pin 155 to fix.The output shaft of described motor is provided with driving gear 150, described driving shaft is provided with driven gear 154, described driving gear and driven gear engaged transmission.
The operation principle of this presser foot of embroidery machine height automatic regulating apparatus is:
Motor 156 is by output shaft output torque, driving gear 150 engages with driven gear 154 and realizes deceleration, driven gear 154 drives driving shaft 151 to rotate, driving shaft 151 drives driving cam 168 to rotate respective angles, then, first connecting rod 152, second connecting rod 153 and presser feet drive hinge pin 155 action in turn, and eccentric cam 157 is by regulating the center of presser feet lever 162 circular motion; Change eccentric center, thus the height of presser feet 165 is changed.
Described driving cam 168 side is provided with the set square 158 of an isosceles triangle, and bottom described set square, one jiao is rotationally connected with on driving shaft, and presser feet drives hinge pin to be rotationally connected with bottom set square on another angle.This set square is relatively-stationary, but driving shaft and presser feet drive hinge pin all can rotate relative to this set square.
The other end of described presser feet lever is provided with circular hole, and described eccentric cam 157 is located in described circular hole.As shown in Figure 4, when eccentric cam 157 rotates, the center of rotation A of eccentric cam is constant, but the center of rotation B of presser feet lever changes, in this process, the center of rotation A of eccentric cam and the line of center of rotation B of presser feet lever and the angle of horizontal plane are changed to D by U, and the height of two state presser feets produces a presser feet difference in height simultaneously, thus regulate the height of presser feet.
Described presser feet drive block 163 comprises cylindrical body, and the bottom faces of described cylindrical body is provided with the lower convex platform protruded to presser feet direction to presser feet side, the top surface of described cylindrical body is provided with convex platform to presser feet drive link side, described convex platform and presser feet drive link hinged.Described presser feet lever is provided with the side protuberance vertical with presser feet lever at adjacent eccentric cam end, and the fulcrum of presser feet lever is located at protuberance end, side.Protuberance end, side is by a hinge on a cam 161, and this cam is installed on a camshaft 160.
In addition, motor 156 is provided with inductor 166 detect the anglec of rotation of output shaft and feed back to the controller of motor.
The highly automated method of adjustment of presser foot of embroidery machine is illustrated below in conjunction with Fig. 4, on the controller according to the difference input corresponding setting presser feet height of shank, when colour changing and when changing shank, controller controls the rotational angle of motor 156 corresponding to setting presser feet height and rotates, and driving shaft 151 is rotated, then, cam link mechanism and presser feet drive hinge pin 155 to link, when presser feet drives hinge pin to rotate, eccentric cam 157 fixed thereon rotates, the centre of motion of presser feet lever 162 is changed simultaneously, thus drive presser feet drive link 169 and presser feet drive block 163 to regulate the height of presser feet 165.
Controller controls the rotation that motor carries out just (+) anti-(-) direction, in motor 156 course of work, the inductor 166 that motor is installed detects the anglec of rotation of output shaft and feeds back to controller, after output shaft rotates to the angle of setting, controller controls motor 156 and stops operating.
