Description
Technical Field
The utility model belongs to the technical field of sewing equipment, a three-wire machine leads yarn device is related to.
Background
The overedger is also called as a hemming machine, is divided into three-line machine, four-line machine and five-line machine, the overedger part of the three-line machine has higher strength, and is used for sewing a garment piece or closing a shoulder and a sleeve in the production process of an operating coat, the working process of the three-line machine is intermittently performed, a plurality of yarns need to be respectively provided with a tensioner for tensioning and traction, the problems of yarn running and yarn breakage are easily caused in the starting and stopping process, and the yarns are difficult to keep synchronous.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned problem that prior art exists, provide a three-way quick-witted yarn device of leading, the utility model aims to solve the technical problem how realize the synchronous of many yarns and pull and the tensioning.
The purpose of the utility model can be realized by the following technical proposal: the yarn guiding device of the three-wire machine is characterized by comprising a mounting seat and two mounting plates fixed on the mounting seat, wherein the two mounting plates are parallel to each other, an even number of connecting pins are fixedly arranged between the two mounting plates, an oval yarn guiding wheel is rotatably connected onto the connecting pins through torsional springs, the adjacent yarn guiding wheels can be mutually compressed, and every two yarn guiding wheels are a threading group.
Furthermore, the inner side surface of the mounting plate is provided with a notch, and the end part of the yarn guide wheel is inserted into the notch.
Furthermore, the number of the yarn guide wheels is six.
The threading mode of the yarn is as follows: two guide wheels are a set of, and the yarn is the S type in the shape of wearing to establish between two guide wheels, and when yarn tension was less, the major axis end of adjacent guide wheel supported each other and leaned on, made the yarn that passes compressed tightly, and when the yarn received certain pulling force, the guide wheel took place to twist reverse, made to link to each other and had the clearance between the guide wheel, did benefit to the yarn and smoothly passed through.
The device not only can realize the simultaneous traction and the guide of a plurality of yarns, but also can provide a certain tension force, and can immediately clamp the yarns when the machine is stopped, thereby avoiding yarn running and yarn breaking and ensuring the synchronization of the yarns.
Drawings
Figure 1 is a schematic structural diagram of the yarn guide device.
Figure 2 is a schematic structural diagram of the yarn guiding device when the yarn tension is small.
Figure 3 is a schematic structural view of the yarn guiding device when the yarn tension is large.
In the figure, 1, a mounting seat; 2. mounting a plate; 3. a connecting pin; 4. a yarn guide wheel; 5. a recess.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 to 3, the yarn guide device comprises a mounting base 1 and two mounting plates 2 fixed on the mounting base 1, wherein the two mounting plates 2 are parallel to each other, an even number of connecting pins 3 are fixedly arranged between the two mounting plates 2, an oval yarn guide wheel 4 is rotatably connected to the connecting pins 3 through torsion springs, the adjacent yarn guide wheels 4 can be mutually compressed, and every two yarn guide wheels 4 are a threading group.
The inner side of the mounting plate 2 has a recess 5, and the end of the thread-guide wheel 4 is inserted in the recess 5.
As thinning, six yarn guide wheels 4 are arranged, and every two yarn guide wheels are in a group.
The threading mode of the yarn is as follows: two thread guide wheels 4 are a set of, and the yarn is the S type in the shape of wearing to establish between two thread guide wheels 4, and when yarn tension was less, the major axis end of adjacent thread guide wheel 4 supported each other and leaned on, made the yarn that passes compressed tightly, and when the yarn received certain pulling force, thread guide wheel 4 took place to twist reverse, made to have the clearance between the continuous thread guide wheel 4, did benefit to the yarn and smoothly passed through.
The device not only can realize the simultaneous traction and the guide of a plurality of yarns, but also can provide a certain tension force, and can immediately clamp the yarns when the machine is stopped, thereby avoiding yarn running and yarn breaking and ensuring the synchronization of the yarns.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
