[0015] The beneficial effects of the present invention are:

[0016] By setting a control device, when sewing the toes of the socks, the first motor is started first, the rotating shaft drives the rotating rod to rotate, and the rotating rod drives the rotating disk to rotate until the squeezing rod squeezes the sliding rod. At this time, the fixed plate squeezes the starting switch, the delay switch and the stop switch. The stop switch controls the first motor to stop, so that the rotating disk no longer rotates, and the starting switch starts the second motor, so that the rotating shaft drives the rolling rod to rotate, so that the bottom sock on the inclined platform is rolled and falls onto the rotating disk. The delay switch controls the cylinder and the electric telescopic rod to start after a short delay. When the electric telescopic rod starts, the pressing piece is controlled to press the lower sock, and the cylinder drives the syringe to move up and down, so that the needle on the syringe sews the lower sock, and then restarting the first motor can sew the next sock, thereby achieving the effect of convenient loading and saving time.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3A single-needle sewing device for the toe of a hosiery machine comprises a hosiery machine 1. In order to facilitate the automatic sewing of the toe of the socks, a control device is arranged inside the hosiery machine 1. The control device comprises a first motor 2, a rotating rod 3, a rotating disk 4, a squeezing rod 5, a sliding rod 6 and a stop switch 7. When the first motor 2 is started, the rotating shaft drives the rotating rod 3 and the rotating disk 4 to rotate, the rotating disk 4 drives the squeezing rod 5 to make a circular motion to squeeze the sliding rod 6, and the sliding rod 6 slides to squeeze the stop switch 7 to stop the first motor 2.

[0023] In order to ensure that the rotating rod 3 maintains stable rotation, the first motor 2 is fixedly installed at the lower end of the inner part of the hosiery machine 1 body, the rotating rod 3 is fixedly installed on the rotating shaft of the first motor 2, the rotating disk 4 is fixedly installed on the upper surface of the rotating rod 3, and the outer surface of the rotating rod 3 is fixedly installed with a fixed circular plate 31. The outer surface of the fixed circular plate 31 is connected to the internal rotation of the hosiery machine 1, and the squeezing rod 5 is fixedly installed on the side surface of the rotating disk 4. When the first motor 2 is started, the rotating shaft drives the rotating rod 3 to rotate, the rotating rod 3 drives the rotating disk 4 to rotate, and the fixed circular plate 31 is stuck in the hosiery machine 1 and rotates, ensuring that the rotating rod 3 maintains stable rotation.

[0024] In order to ensure that the sliding rod 6 can slide stably in the hosiery machine 1, a slide groove 11 is opened at the right end inside the hosiery machine 1, and the sliding rod 6 is slidably inserted into the inside of the hosiery machine 1. A fixing plate 61 is fixedly installed on the right end surface of the sliding rod 6, and the fixing plate 61 is slidably inserted into the inside of the slide groove 11. The fixing plate 61 slides in the slide groove 11, ensuring that the sliding rod 6 can slide stably in the hosiery machine 1.

[0025] In order to facilitate the automatic control of the start switch 12 and the delay switch 13, a spring 62 is fixedly installed on the right end surface of the fixed plate 61, and the right end surface of the spring 62 is fixedly connected to the inside of the slide groove 11. The inside of the slide groove 11 is respectively fixedly installed with the start switch 12 and the delay switch 13. The start switch 12 is located above the delay switch 13. The spring 62 squeezes the fixed plate 61 so that the left end of the sliding rod 6 can keep extending out of a part of the outside of the hosiery machine 1. The fixed plate 61 squeezes the start switch 12 and the delay switch 13 to start the two switches.

[0026] In order to facilitate automatic loading, the stop switch 7 is fixedly installed inside the slide 11, the stop switch 7 is located below the spring 62, the stop switch 7 is electrically connected to the first motor 2 through a wire, the interior of the hosiery machine 1 is located above the rotating disk 4 and a barrel 14 is fixedly installed, an inclined platform 15 is fixedly installed inside the barrel 14, a fixed column 16 is fixedly installed on the right end of the inclined platform 15, a time relay 17 is fixedly installed inside the barrel 14, the time relay 17 is electrically connected to the start switch 12 through a wire, and the stop switch 7 can control the first motor 2 to stop when it is started. Socks to be sewn are placed in the barrel 14, and the socks are located above the inclined platform 15. The time relay 17 allows the start switch 12 to stop after rotating for the same time each time, so that the rolling rod 19 can just roll down the bottom socks each time.

[0027] In order to facilitate the compression and sewing of the socks, a second motor 18 is fixedly installed inside the barrel 14, and a rolling rod 19 is fixedly installed on the rotating shaft of the second motor 18. The second motor 18 is electrically connected to the starting switch 12 through a wire, and a cylinder 110 and an electric telescopic rod 111 are fixedly installed above the rotating disk 4 inside the hosiery machine 1, and a needle cylinder 112 is fixedly installed at the lower end of the cylinder 110. The cylinder 110 and the electric telescopic rod 111 are electrically connected to the delay switch 13 through a wire, and a pressing piece 113 is fixedly installed at the lower end of the electric telescopic rod 111. When the second motor 18 is started, the rotating shaft drives the rolling rod 19 to rotate, and the cylinder 110 drives the needle cylinder 112 to move up and down. When the electric telescopic rod 111 is started, the pressing piece 113 is controlled to compress the socks below.

[0028] By setting a control device, when sewing the toes of the socks, the first motor 2 is started first, the rotating shaft drives the rotating rod 3 to rotate, and the rotating rod 3 drives the rotating disk 4 to rotate until the squeezing rod 5 squeezes the sliding rod 6. At this time, the fixed plate 61 squeezes the starting switch 12, the delay switch 13 and the stop switch 7. The stop switch 7 controls the first motor 2 to stop, so that the rotating disk 4 no longer rotates, and the starting switch 12 starts the second motor 18, so that the rotating shaft drives the rolling rod 19 to rotate, so that the bottom sock on the inclined platform 15 is rolled and falls onto the rotating disk 4. The delay switch 13 controls the cylinder 110 and the electric telescopic rod 111 to start after a short delay. When the electric telescopic rod 111 is started, the pressing piece 113 is controlled to press the lower sock, and the cylinder 110 drives the syringe 112 to move up and down, so that the needle on the syringe 112 sews the lower sock, and then restarting the first motor 2 can sew the next sock, thereby achieving the effect of convenient feeding and saving time.

[0029] Working principle: when sewing the toes of socks, first start the first motor 2, let the rotating shaft drive the rotating rod 3 to rotate, and the rotating rod 3 drives the rotating disk 4 to rotate until the squeezing rod 5 squeezes the sliding rod 6. At this time, the fixed plate 61 squeezes the starting switch 12, the delay switch 13 and the stop switch 7. The stop switch 7 controls the first motor 2 to stop, so that the rotating disk 4 no longer rotates, and the starting switch 12 starts the second motor 18, so that the rotating shaft drives the rolling rod 19 to rotate, so that the bottom sock on the inclined platform 15 is rolled and falls onto the rotating disk 4. After a short delay, the delay switch 13 controls the cylinder 110 and the electric telescopic rod 111 to start. When the electric telescopic rod 111 is started, the pressing piece 113 is controlled to press the lower socks, and the cylinder 110 drives the syringe 112 to move up and down, so that the needle on the syringe 112 sews the lower socks, and then restarts the first motor 2 to sew the next sock.
