A bearing seat 44 is locked to the position of the through hole 42 corresponding to the through hole 42 respectively. The bearing seat 44 can be fitted into the through hole 42. The bearing seat 44 is provided with a bearing 45, a spindle 5 and two support rods. The two ends of the bearing shaft 7 and the two supporting rods 7 are respectively pivoted on the two bearing plates 4 by bearings 45, so that the mandrel 5 and the two supporting rods 7 can be Rotate smoothly. Screw holes 51, 71 may be respectively disposed at two ends of the spindle 5 and the support rod 7, and the screw holes 51, 71 are respectively screwed with a locking screw 46, and the locking screw 46 can be tightly locked with the inner ring of the bearing 45. After the locking screws 46 at both ends are locked, the mandrel 5, the support rod 7 and the two bearing plates 4 can be integrated into one body.

The pulley set 8 is connected between the two support rods 7 and the spindle 5, and the pulley set 8 can be disposed on one side thereof, and the support rod 7 is rotated in a belt transmission manner to make the elastic yarn wheel placed on the support rod 7. 10 can send the yarn out at a constant speed. In this implementation For example, the pulley set 8 is disposed on the outer side of one of the carriers 4, and the pulley set 8 can include a first pulley 81, a second pulley 82, and a third pulley 83. The first pulley 81 and the second pulley 82 The third pulley 83 is fixed to one end of the spindle 5 and the two support rods 7, respectively, and a belt 84 is disposed between the first pulley 81, the second pulley 82 and the third pulley 83. An outer cover 9 can be further disposed on the outer side of the pulley set 8. The outer cover 9 is fixed to the carrier plate 4 by screwing or the like, and the outer cover 9 can cover members such as the pulley set 8 to have better dustproof effect. . Therefore, the driving wheel 2 can drive the mandrel 5 to rotate through the transmission shaft 3 and the gear set 6, and rotate the two supporting rods 7 through the pulley set 8, so that the elastic yarn wheel 10 disposed on the two supporting rods 7 is driven to operate. The rubber yarn can be fed into the knitting machine.

At present, most of the rubber yarn feeders available on the market drive four elastic yarn wheels for one yarn feeder, but only one driving wheel, so only all the rubber yarns can be fed at the same speed during weaving. In order to improve the characteristics of the fabric, the rubber yarns are required to be divided into two or more yarn feeding speeds to meet the requirements of the fabric. To this end, the creation of a single-line elastic yarn feeder, each yarn feeder drives an elastic yarn wheel 10, and set 2-4 drive wheels 2 and clutch 40 on the transmission shaft 3, so that we can The demand for cloth is divided into 2-4 kinds of yarn feeding speeds.

The single-line elastic yarn feeder of the present invention has a support rod disposed between the two support plates, and two ends of the support rod are pivotally disposed on the two support plates, so that both ends of the support rod are supported by two support plates, and both ends of the support rod are supported. With support points, the support strength is better, the support rod is not easy to shake, the yarn output tension is stable, and the thickness of the two side plates can be reduced to meet the requirements of thinning and light weight. Furthermore, the single-line elastic yarn feeder of the present invention can be made thinner, and when it is placed on the iron ring of the knitting machine, it does not occupy a space, so that the overall size of the knitting machine can be reduced.

However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of patent protection of the present invention. Therefore, the equivalent changes of the present specification and the contents of the drawings are all included in the protection of the present invention.
