Description

A kind of embroidery machine independence presser feet drive system
Technical field
The present invention relates to the embroidery machine field, relate in particular to a kind of embroidery machine independence presser feet drive system.
Background technology
Embroidery machine generally comprises frame, be arranged at head on the frame, lateral arrangement is in going up axle, can laterally be arranged at shank case on the head movably, can be arranged in some shanks, connection on the shank case up or down and drive the shank case and laterally move the needle bar drive device that the shank with the colour changing driving mechanism of selecting a shank job and connection driving selection moves up and down on the frame; Traditional embroidery machine presser feet all is attached on the shank; Back-up ring is set on shank; Presser feet can be arranged on the shank through supporting member up or down; Be arranged with the presser feet spring that is between back-up ring and the supporting member on the shank, shank is moved up and down by needle bar drive mechanism drives during work, and shank descends; Presser feet is pressed on the cloth, and pressure is provided by the presser feet spring; Shank is return, and presser feet reduces last presser feet gradually to the pressure of cloth and leaves cloth, because the presser feet spring force is less; Generally being only applicable to embroider approaches material, and when thick material of embroidery and leather, the frictional force of eedle and sewing is excessive; When reclaiming rising; The insufficient pressure of presser feet, lining can be taken up by eedle, thereby causes phenomenons such as bouncing pilotage, broken string, sewing positioning.To the problems referred to above; The at present existing patent No. is that 200910113690.0 the presser foot independent driving mechanism for embroidery machine and the patent No. are 200810082757.4 embroidery machine; Two patents all are to solve the problems referred to above through the presser feet drive; But the presser foot component of above-mentioned patent all is arranged on the shank case, and this has just determined each shank must be equipped with one group of presser foot component, so not only cost height but also complex structure.
Summary of the invention
The objective of the invention is deficiency, a kind of embroidery machine independence presser feet drive system simple in structure, with low cost is provided to prior art.
The object of the invention is realized through following technical scheme:
A kind of embroidery machine independence presser feet drive system; Be arranged on the embroidery machine head; Comprise axle; It is characterized in that: also comprise the presser bar that can be arranged in up or down on the head and connect the presser feet driving mechanism that the drive pressure foot lever moves up and down that said presser feet driving mechanism comprises being arranged at saidly to be gone up presser feet cam on the axle, be fixedly set in the drive block on the presser bar and be connected the transmission component that moves up and down that is used for rotatablely moving of presser feet cam is converted into drive block between presser feet cam and the drive block.
Further, said presser bar is provided with and is arranged with first spring that is compressed between back-up ring and the head on a back-up ring, the said presser bar.
Further; Said transmission component comprise can around swing arm that fixing point rotates, can around drive rod that fixing point rotates, be articulated in the first connecting rod between drive rod and the said drive block and be articulated in swing arm and drive rod between second connecting rod; Said presser feet cam outer peripheral face is formed with the track groove, and said swing arm is provided with the drive pin that matches with the track groove.
Further; Said transmission component also comprises height adjustment mechanism; Said height adjustment mechanism comprises motor, be arranged at eccentric wheel on the motor output shaft, can rotate and the cramp bar that fits with the eccentric wheel outer peripheral face, is connected second spring that is used to make cramp bar and eccentric wheel maintenance applying with cramp bar around fixing point, and the fixing point of said drive rod is arranged on the cramp bar.
Further, said height adjustment mechanism also comprises the grating that is connected with motor output shaft, the grating detector that matches with grating, but is arranged to the amount of feeding of grating detector response light gate signal with the control motor.
Further, said head is provided with on vertically arranged guide post, the said drive block and is formed with the gathering sill that matches with guide post.
The present invention has following beneficial effect:
Presser bar is arranged on the head; Match with the shank on the shank case; Colour changing drive mechanism shank case is laterally mobile to carry out colour changing to select a shank to cooperate with presser bar, so only needs a presser bar and some shanks that different colours embroidery line is set to cooperate and just can realize the polychrome embroidery, thereby reduce the quantity of presser bar; Practice thrift cost, simplified structure; Presser bar is by presser feet driving mechanism drive; Can increase the pressure of presser feet, prevent embroidery machine can be stitched embroider thick material and leather because of lining is taken up phenomenons such as the bouncing pilotage that causes, broken string, sewing positioning by eedle; Presser bar is by presser feet driving mechanism drive in addition; So just can not cause the active force influence, embroider the speed of doing, improve output thereby improve machine to needle bar drive device; First spring is set improves the pressure of presser bar and the speed of actions that improves presser bar; The presser feet driving mechanism is made up of presser feet cam, drive block and transmission component, has advantages such as simple in structure, that action is accurate; Height adjustment mechanism is set passes through to regulate the upper and lower stroke of the height of drive rod fixing point, thereby adapt to lining without thickness with the adjusting presser bar; Cooperate the amount of feeding of control height adjustment mechanism motor through grating and grating detector, thereby accurately regulate presser bar, improve the action accuracy of presser bar.
