Abstract
The invention discloses a sliding needle rod, which relates to the needle rod structure modification of a quilting machine or quilting machine. The invention aims at the problems and provides a sliding needle rod that the machine is not required to stop to compensate stitches when the stitch is broken, can not generate repeated stitches, and can control the pattern varieties at will. The invention comprises a needle rod sleeve, and has the structure key points that a needle rod hole and a pushing rod hole are respectively arranged at the both ends of the needle rod sleeve, a dump club is arranged on the inner wall of the needle rod hole side, a pushing rod groove, a deep groove, and a shallow groove are arranged on the inner wall of the pushing rod hole side, the ends of the deep groove and the shallow groove are equipped with skewed tooth; a spring is arranged between the end club and the inner wall dump club of the needle rod inside the needle rod hole, edges corresponding to the pushing rod groove of the needle rod sleeve are arranged on the excircle of the pushing rod inside the pushing rod hole; end surface teeth corresponding to the end surface teeth on the pushing rod are arranged on the inner circle of one side of a rotator arranged between the needle rod and the pushing rod, and the edges on the excircle of the rotator correspond to the deep groove and the shallow groove on the inner wall.
Description
Technical field:
The present invention relates to the improvement of quilting machines or needle bar of sewing machine structure.
Background technology:
The eedle of tradition quilting machines is fixed on the shank by screw, and eedle fixes on the pin chi by the shank clamping, and perhaps eedle directly is fixed on the pin chi with screw.In a word, the relative position of eedle, shank and pin chi is changeless.All eedles that the drive that moves up and down of pin chi is fixed on it move up and down simultaneously, realize the quilting operation of eedle to sewing.
In the real work of quilting machines, if break, cause and break to shutting down this section not formation of corresponding stitching on the sewing in the time because of the suture on a certain eedle, can only mend pin by manual type in this case.If sewing turns back to break point and mends pin by machine, because all eedles are finished identical operations, just all eedles all can remove to mend pin, cause unnecessary repetition stitching, are worthless in practical operation.
Quilting machines is to lean on row's pin combination dealing of pin to become style in real work in addition, and each style changes all needs manually to adjust eedle, can not arbitrarily control the variation of style.
Summary of the invention:
The present invention is exactly at the problems referred to above, and a kind of slide needle lever that breaks and need not shut down, can not produce the repetition stitching when mending pin, can arbitrarily control the style variation is provided.
The present invention adopts following technical scheme: the present invention includes the shank cover, its structural feature is that the two ends of shank cover are respectively arranged with needle bar hole, push-rod hole, the inwall of needle bar hole side is provided with boss, the distolateral inwall of push-rod hole is provided with push rod groove, deep trouth, shallow slot, and deep trouth, shallow slot end have helical teeth; Between the end platform of the shank in the needle bar hole and the inwall boss is spring, and the cylindrical of the push rod in the push-rod hole has the corresponding rib of push rod groove with the shank cover; Have with the corresponding end face tooth of push rod end face tooth on the circle in one side of the rotor between shank and the push rod, the rib on the cylindrical of rotor and the deep trouth of inwall, shallow slot are corresponding.
Beneficial effect of the present invention:
Shank of the present invention can be as required, any eedle is rested on work or the idle position (because shank of the present invention is slideable shank, slidably and be locked in one of a high position or two positions of low level, because eedle can not sting sewing when high-order, can not contact with end shuttle, can on sewing, not form stitching, so be off-position); Like this, just can make the work of a broken string eedle, and remaining eedle only moves and does not work, and has avoided the stitching that repeats, and has guaranteed crudy, and has reduced the waste of material.And can any eedle be rested on work or the idle position, arbitrarily arrange style to change.

The specific embodiment:
The present invention includes shank cover 12, the two ends of shank cover 12 are respectively arranged with needle bar hole 13, push-rod hole 1, the inwall of needle bar hole 13 sides is provided with boss 11, and push-rod hole 1 distolateral inwall is provided with push rod groove 16, deep trouth 15, shallow slot 17, and deep trouth 15, shallow slot 17 ends have helical teeth 18; Between the end platform 8 of the shank 10 in the needle bar hole 13 and the inwall boss 11 is spring 9, and the cylindrical of the push rod 2 in the push-rod hole 1 has the push rod groove 16 corresponding ribs 3 with shank cover 12; Have with push rod 2 end face teeth 4 corresponding end face teeth 5 on the circle in one side of the rotor 6 between shank 10 and the push rod 2, the rib 7 on the cylindrical of rotor 6 and the deep trouth 15 of inwall, shallow slot 17 are corresponding.
The cylindrical of shank 10 is provided with rib 20, and rib 20 is corresponding with the groove 19 on the needle bar hole 13; Can prevent to rotate in shank 10 runnings.
Below in conjunction with a description of drawings course of action of the present invention:
Push rod 2 under external force, the push rod groove 16 along the inwall of shank cover 12 moves from top to bottom, drives rotor 6 and shank 10 and moves downward; Then, the end face tooth 5 that spring 9 moved upward, promoted rotor 6 rotates along the end face tooth 4 of push rod 2, and at this moment, the rib 7 on rotor 6 cylindricals is fallen on the shallow slot 17 in the shank cover 12, and shank 10 is in the position on top.When external force promoted push rod 2 once more, push rod 2 moved along the inwall push rod groove 16 of shank cover 12, drove rotor 6 and shank 10 and moved downward; Then, the end face tooth 5 that spring 9 moved upward, promoted rotor 6 rotates forward along end face tooth 4 continuation of push rod 2, and at this moment, the rib 7 on rotor 6 cylindricals is fallen in the deep trouth 15 of shank cover 12, and shank 10 is in the position of bottom.The position on the top of shank 10 is exactly the off working state of shank 10, and promptly the eedle 14 of shank 10 breaks away from sewing; The lower position of shank 10 is exactly the duty of shank 10, and promptly 14 pairs of sewings of the eedle of shank 10 carry out quilting work.
