Abstract
The utility model relates to a yarn take-up spring device for a sewing machine. The purpose of the utility model is to provide a yarn take-up oscillating device of a sewing machine, which can regulate the tightness degree of sewing yarns. The movement displacement of the sewing yarns are made stable, the sewing yarns are positioned accurately and the yarn disordered phenomenon or the yarn broken phenomenon is avoided. The utility model comprises a supporting frame, and a fixed plate is hinged with the supporting frame by a movable pin. A restoring spring is arranged between the fixed plate and the supporting frame. Both sides of the fixed plate are respectively provided with a yarn drawing lever and a yarn returning lever. The lower part of the supporting frame is provided with a yarn take-up lever, and the end of the yarn drawing lever, the end of the yarn returning lever and the end of the yarn take-up lever are provided with yarn penetrating holes. The utility model easily regulates the tightness of the sewing yarns of the sewing machine. The regulation is very convenient, and suitable elasticity can be easily regulated to, the positioning of the sewing yarns are accurate and the sewing machine operates in the optimum state.
Description
Technical field
The utility model relates to a kind of sewing machine parts, particularly relates to a kind of sewing machine take-up pendulous device that can conveniently reclaim suture.
Background technology
Sewing machine is by band linear slit pin suture to be passed the fabric that is sewn, and the reciprocating motion by suture needle drives suture and passes fabric repeatedly, by thread take-up mechanism the interlocking of suture pitch of the laps is realized sewing up again.Suture needle needs to make suture to keep certain force of strain in the process that comes and goes, so on sewing machine, be provided with thread take-up spring, spacing colluding, thread take-up spring is connected support with a spacing end that colludes, and its tie point makes suture keep guiding suture needle again into after the certain force of strain at a distance of certain distance.When joining ratio is thin, during fabric springy, the stitching mouth of fabric also needs certain rate of tension, when this just required the reciprocating motion drive suture of suture needle to pass fabric, suture needle startup inserting needle repeatedly, suture will have certain surplus line, made the stitching mouth certain rate of tension be arranged to cooperate elastic fabric.The thread take-up spring of existing sewing machine is fixedlyed connected with the support position, and by the location decision of regulating spring, the adjusting program bothers its elastic force very much, and is difficult for being adjusted to suitable degree, makes the needle sports instability, produces wire jumper, line of fall phenomenon fully.
Summary of the invention
The purpose of this utility model just provides a kind of sewing machine take-up pendulous device that can regulate the suture tightness, to overcome shortcoming above-mentioned in the prior art, makes the moving displacement of suture stable, and random line or broken string are avoided in the suture accurate positioning.
For reaching above-mentioned purpose, the utility model adopts following technical scheme:
A kind of sewing machine yarn take-up spring device includes support, and fixed head is by the removable pin hinge bracket, be provided with back-moving spring between fixed head and the support, both sides respectively are provided with stay rod, loop line bar on the fixed head, and the support bottom is provided with thread take-up tension lever, and stay rod, loop line bar, thread take-up tension lever end are provided with through wires hole.
The utility model utilize stay rod, loop line bar, thread take-up tension lever under normal conditions its separately the through wires hole top of end near linear, when the suture needle inlet wire, the suture pulling force drives fixed head and rotates, make that stay rod is low, loop line bar height, suture passes the through wires hole of stay rod, thread take-up tension lever, loop line bar, forms a triangle this moment; During thin, the springy fabric of joining ratio, suture will have certain surplus line when suture needle started inserting needle, make the stitching mouth certain rate of tension be arranged to cooperate elastic fabric, when suture needle starts inserting needle once more, back-moving spring drives the fixed head rotation and resets, and the suture of stay rod, thread take-up tension lever, loop line bar is replied from triangle and is near linear at this moment, and suture has certain surplus line, make suture that certain Zhang Du be arranged, avoid the suture wire jumper, sew up tight-lipped mistake.The utility model solves the difficult problem of regulating of suture elasticity that existing thread take-up mechanism exists, reach the effect of easy adjustment suture degree of tightness, not only regulate very conveniently, and be easy to be adjusted to suitable elastic force, the suture accurate positioning makes sewing machine be operated in optimum state.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the working state figure of the utility model embodiment.
Fig. 3 is the schematic perspective view of the utility model embodiment.
Fig. 4 is the use location figure of the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
The utility model parts comprise: stay rod 1, support 2, steady pin 3, thread take-up tension lever 4, removable pin 5, spring 6, fixed head 7, loop line bar 8, suture 9.
Fixed head 7 is provided with back-moving spring 6 by removable pin 5 hinge brackets 2 between fixed head 7 and the support 2, and both sides respectively are provided with stay rod 1, loop line bar 8 on the fixed head 7, and support 2 bottoms are provided with thread take-up tension lever 4, and stay rod 1, loop line bar 8, thread take-up tension lever 4 ends are provided with through wires hole.
Thread take-up tension lever 4 connects supports 2 by steady pin 3, and steady pin 3 can be regulated the angle direction of thread take-up tension lever 4, makes stay rod 1, loop line bar 8, thread take-up tension lever 4 its through wires hole top (as shown in Figure 1) near linear of end separately under normal conditions; Thread take-up tension lever 4 is provided with triangle through wires hole upwards away from steady pin 3 ends.A side sets firmly stay rod 1 on the fixed head 7, opposite side sets firmly loop line bar 8, stay rod 1 is provided with downward triangle through wires hole away from fixed head 7 ends, loop line bar 8 is provided with downward triangle through wires hole away from fixed head 7 ends, stay rod 1 and loop line bar 8 are gone back the available metal material and are integrated into stay rod 1 and loop line bar 8 by the metal material moulding.
Stay rod 1, thread take-up tension lever 4, loop line bar 8 be its through wires hole top (as shown in Figure 1) near linear of end separately under normal conditions, when suture needle 9 inlet wires, suture 9 pulling force drive fixed head 7 and rotate, make stay rod 1 low, loop line bar 8 height, suture 9 passes the through wires hole of stay rod 1, thread take-up tension lever 4, loop line bar 8, form a triangle (as shown in Figure 2) this moment, and stay rod 1 does not give a discount large bending needle when inlet wire.When suture needle starts inserting needle once more, back-moving spring 6 drives fixed head 7 rotations and resets, the suture 9 of stay rod 1, thread take-up tension lever 4, loop line bar 8 is replied from triangle and is near linear at this moment, this moment, suture 9 had certain surplus line, made suture 9 that certain Zhang Du be arranged, and avoided suture 9 wire jumpers, sewed up tight-lipped mistake, utilize sewing machine clamp degree of tightness machinery simultaneously, make suture 9 degrees of tightness freely, suture 9 conveying of keeping in balance, line is unimpeded.
