The active block is driven by a crank to do upper and lower sports on a guide rod, and the needle bar is driven to work by impelling the connecting shaft. The utility model has the advantages of simple structure, convenient repair and use and low cost.
Description
The utility model relates to the garment machinery embroidery machine, particularly the shank replacing mechanism of embroidery machine head.
Existing computerized emboridering machine has single needle bar and spininess bar various ways.The single needle bar is only used a kind of line of color, and multicoloured floral designs are restricted to embroidering; And spininess bar (3,6,8 pins etc. are arranged) the multicoloured floral designs of can embroidering, but its transposing needle bar mechanism complexity, the computer of Pei Heing is also had relatively high expectations with it, and the manufacturing cost height keeps in repair numerous tired.
The purpose of this utility model provides a kind of shank replacing mechanism of manual spininess embroidery machine.
The purpose of this utility model is finished by following technical solution: it comprises head shell, panel, the shank that has spring bradyseism mechanism, in described head shell, be longitudinally set with a guide rod, this guide rod epimere is a circular shaft, handwheel from top to bottom is slidingly connected, runner and train wheel bridge, described handwheel, runner and train wheel bridge link successively to join and rotate, and between this runner and head shell, be provided with detent mechanism, the guide rod stage casing has guide-track groove, set loose piece on it, this loose piece is driven and can be moved up and down on described guide rod by transmission mechanism, the guide rod hypomere bottom plate that is slidingly connected, between described train wheel bridge and described bottom plate, be provided with needle bar frame, be provided with at least two above-mentioned shanks that have spring bradyseism mechanism in this needle bar frame, each shank is provided with the promotion connecting axle, and this promotion connecting axle matches with described loose piece lateral groove, can embed in this groove, also be provided with thread take-up tension lever on described head shell, this thread take-up tension lever also is provided with the threading hole with the shank similar number.
The epimere of above-mentioned guide rod and on handwheel, runner and train wheel bridge can be positioned at above-mentioned head shell (at this moment, the head shell windowing), also can be positioned at outside the head shell.If the epimere of guide rod stretches out outside the head shell, described handwheel and runner also are located at the outside of head shell, and this runner connects connecting rod, and the interior train wheel bridge of the deep-slotted chip breaker hole of this connecting rod by head shell and head shell connects.
Above-mentioned needle bar frame can have multiple shape, as long as can install the shank that has bradyseism mechanism, and it can be worked.Needle bar frame a kind of is shaped as three layers of horizontal stripe and vertically connects together at two ends, every horizontal stripe establish some holes (with pin at should).
The detent mechanism that is provided with between above-mentioned runner and the head shell is to establish arc groove on runner, also is provided with dark pit point in the groove, establishes the steel ball spring pin on head shell.This steel ball spring pin is in the cylinder spring to be housed, and the top card is established steel ball, and this steel ball is outwards outstanding under spring action, and power effect is outside inwardly compressed into.Detent mechanism also can have various ways.
Each above-mentioned shank can be provided with spacing collar; Between shank and above-mentioned loose piece, be provided with the guide plate of the above-mentioned promotion connecting axle of guiding activity.
The lower end of above-mentioned train wheel bridge, the termination of bottom plate can sheathedly tighten up circle.
Above-mentioned loose piece, handwheel, runner, train wheel bridge, bottom plate, head shell, needle bar frame etc. all can be by a plurality of assemblies of part in addition.Wherein above-mentioned loose piece is by a nested guide hole that passes through for above-mentioned guide rod of offering, and sets bearing shell in this guide hole, and this nested side is established above-mentioned groove, and opposite side Bao Gu tightens up frame, and this fixed frame is connected with above-mentioned crank.
The course of work of the present utility model is: if need be assigned a new job shank, stop the shank work activities, hand rotates handwheel, handwheel drives runner, and runner drives train wheel bridge, train wheel bridge rotates needle bar frame and shank, and shank is done circular motion, promotion connecting axle on a certain shank is embedded in the loose piece side groove (having changed another shank), simultaneously, also relevant work of the detent mechanism on the runner enters anchor point this moment.Then, crank drives loose piece and moves on guide rod, and loose piece promotes to connect the shank work that drives again.Cam driven thread take-up tension lever motion simultaneously matches with shank.
The utility model adopts runner to drive train wheel bridge and realizes the shank transposing, has solved former spininess bar and has changed the linkage complexity, the high problem of maintenance requirement.Simple in structure, to make more conveniently, cost is low, and the computer program that matches also simplifies greatly, has reduced production cost.Former board cost is 80,000 yuan; Now be 1.5 ten thousand yuan.Simultaneously, easy to maintenance, originally the technology operation to maintenance mans need to require six grades more than the pincers worker, and existing general three grades of pincers worker get final product.
If the outside that above-mentioned handwheel and runner are located at head shell, then hand is changed hands wheel conveniently, understands.
If above-mentioned detent mechanism adopts on the runner and establishes groove, pit point, establish the steel ball spring pin on the head shell, then simple in structure, easy to operate, positioning stablity guarantees that shank can not move when the operating position.
If above-mentioned shank is provided with spacing collar, then can adjust the distance that moves up and down of shank, guarantee shank work.
If be provided with guide plate between above-mentioned shank and the loose piece, then can rise the promotion connecting axle, the motion guide effect of shank, vertical precision when guaranteeing shank work can not produce skew.
If the degree of tightness that train wheel bridge and bottom plate are enclosed within guide rod then can be regulated in the lower end of above-mentioned train wheel bridge, and the sheathed circle that tightens up in bottom plate termination.
If above-mentioned loose piece adopts other part sub-assembly, then be convenient to processing, other part is changed in maintenance, sets bearing shell in guide hole, then helps lubricating, and is wear-resisting.
