Description
Technical field
The present invention stablizes the drawing lines mechanism of suture location about a kind of sewing machine headstock part that is positioned at, and has the sewing machine of plural needle bar when carrying out needle bar switching especially for a kind of, is used for stable plural number bar suture drawing lines mechanism of length in drawing lines.
Background technology
Press, general sewing machine must configure the relative lower horn of horn and lower section and needle plate, synchronize to drive Yarn taking-up mechanism and crankshaft arrangement with main shaft inside upper horn, to drive the needle bar mechanism of headstock part, and lower horn is provided with hook line apparatus in being provided with below cloth feeding mechanism and needle plate, drive to be sewn under line by the suture needle of needle bar mechanism and back and forth puncture cloth, and coordinate Yarn taking-up mechanism and the correct operation sequential hooking line apparatus to carry out folding and unfolding suture, to carry out sewing operation.
Wherein, Yarn taking-up mechanism is the most all positioned at above needle bar mechanism to guarantee the tension force of suture, and reduce the suture resistance through Yarn taking-up mechanism, and the most on the market in addition to a kind of spininess bar type embroidery machine, fresh have the sewing facility that can directly carry out needle bar switching less, but because general spininess bar type embroidery machine still has the shortcoming that bulky and driving means feeding table top movement travel must lengthen, therefore, it is necessary that innovative design goes out in fact a kind of in the case of sewing datum mark and bottom platform invariant position, the different needle bar of directly switching can be needed to carry out the sewing machine sewed according to sewing.
But, once sewing locomotive head position is devised ring-type needle bar casket and switch plural number needle bar, and Yarn taking-up mechanism also must process several sutures many simultaneously, if so suture not being worn path to be controlled by, after needle bar switches, can cannot stablize plural number suture length in drawing lines so that the tension change of plural number suture, and then affect sewing operation.
Summary of the invention
The main object of the present invention, aim to provide and a kind of carry out plural number bar suture for convertible needle bar held sewing machine and stablize the drawing lines mechanism of line taking, make the length of plural number suture after the string holes of thread take-up tension lever and the pin hole of eedle, will not change because of after sewing machine switching needle bar.
The secondary objective of the present invention is between the pin hole of the string holes of thread take-up tension lever, eedle have a clamp design further, when allowing sewing machine sew, releasable use in suture clamp untapped suture simultaneously, it is to avoid plural number suture departs from from eedle pin hole.
After another object of the present invention is to thread take-up tension lever cooperation wire-threading device use, the position of thread take-up tension lever can be allowed to be no longer limited by directly over needle bar, facilitate the configuration design of whole sewing machine table.
For reaching described purpose, the drawing lines mechanism of needle changeable sewing machine of the present invention mainly comprises a thread take-up tension lever, a ring-type needle bar casket and plural number bar suture, above-mentioned thread take-up tension lever has a swinging end and a take-up end, above-mentioned swinging end is in order to drive above-mentioned take-up end upper and lower displacement, and above-mentioned take-up end has a plurality of string holes；Above-mentioned ring-type needle bar casket has an axis of rotation and the needle bar hole set is arranged at a plurality of interval, and in being internally formed a perforative space from top to bottom, above-mentioned distance between each needle bar hole and above-mentioned axis of rotation is the most identical, and be installed with a needle bar with eedle respectively in each needle bar hole, and each eedle has a pin hole；And above-mentioned suture is sequentially through the drawing lines path collectively formed by the string holes of above-mentioned thread take-up tension lever, the above-mentioned perforative space of ring-type needle bar casket and the pin hole of above-mentioned eedle.
In a preferred embodiment, the present invention is provided with a location dish bottom above-mentioned ring-type needle bar casket, above-mentioned location dish has a plurality of through wires hole around around above-mentioned axis of rotation, penetrates for above-mentioned a plurality of sutures, and above-mentioned location tray bottom is further provided with a wire-clamping device.
Above-mentioned wire-clamping device is provided with a clamp piece being covered in dish a plurality of through wires hole one end, above-mentioned location, above-mentioned clamp piece has a clamp face that can cover above-mentioned a plurality of through wires hole, and on above-mentioned clamp face, offer a breach, with one of them of corresponding above-mentioned a plurality of through wires holes.
In a possible embodiments, above-mentioned wire-clamping device is further provided with a shaft member, a spring and a nut and jointly coordinates above-mentioned clamp piece formation one to clamp suture means.The most also a driving shaft can be designed to coordinate above-mentioned clamp piece to form release suture means.
Furthermore, in another embodiment, the present invention also can be directly provided with a thread clamping mechanism between above-mentioned thread take-up tension lever and ring-type needle bar casket, the most above-mentioned thread clamping mechanism is provided with a pressing line disk, above-mentioned pressing line disk has the press fixing piece of a plurality of concatenation, and above-mentioned a plurality of press fixing piece side is provided with a loose ends unit and and elapses the driver element of above-mentioned loose ends unit, above-mentioned loose ends unit is provided with a fulcrum, and it is pivoted with a plurality of with above-mentioned press fixing piece correspondence position thread tension releasing disc on above-mentioned fulcrum, and above-mentioned driver element optionally pushes against between the two of which that one of them of above-mentioned a plurality of thread tension releasing disc is cut into a plurality of press fixing piece, with the suture that release is selected.
