Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

1-5, an efficient yarn feeding mechanism for a hosiery machine includes a pay-off frame 1 and a wiring assembly, wherein:

The board of the pay-off rack 1 includes a main body 101. The upper surface of the main body 101 is provided with a chute 102 and a sinker. The sinker is located at both ends of the chute 102. The chute 102 is slidably connected with a support. Block 103, and the upper surface of the support block 103 is rotatably connected with a shaft 104, the side wall of the shaft 104 is rotatably sleeved with a circular tube 13, and the side wall of the shaft 104 is fixedly sleeved with a disc 14. In this kind of In the design, due to the design of uninterrupted yarn feeding, during use, each yarn needs to be equipped with two shafts 104 for yarn feeding, and since the wiring assembly is immovable, for the convenience of use, a chute is used. 102 is matched with the sinker, wherein the cross-section of the chute 102 is T-shaped. After the user puts the yarn bobbin with yarn on the shaft 104, once the yarn on the bobbin is used up, move away from the knotter. Slide the support block 103 in the 8-direction, and remove the support block 103 from the sinker, then insert the support block 103 into the chute 102 from the chute 102 near the sinker in the 8-direction of the knotter, and replace with a new yarn Finally, pull out the yarn end on the new bobbin and put it into the knotter 8 for standby use, so that the addition of the bobbin can be completed when the sock knitting machine and the yarn feeding mechanism are running. Thereby, the downtime is reduced and the production efficiency is improved. In addition, the circular tube 13 is provided to facilitate the user to hold the shaft 104 and move the support block 103 and the shaft 104 when the shaft 104 rotates, while the circular disk 14 is provided for Avoid the rotating bobbin directly pressing on the user's hand.

The wiring assembly includes a support frame 2 that is fixedly connected to the pay-off frame 1. The support frame 2 is rotated upward and is provided with a pinch mechanism. The pinch mechanism includes two driving rollers 9 and two driven rollers 10. One end of the driving roller 9 is fixedly connected with a gear 11, and the two gears 11 are meshed with each other. Fixed connection, in which the driving roller 9 cooperates with the driving motor 12 to pull the yarn to the hosiery machine, and the driven roller 10 uses the friction between itself and the support frame 2 to make the driving roller 9 and the driven roller 10. After the yarn on the bobbin is used up and the end of the yarn passes through the driven roller 10, the yarn cannot support the pressing rod 3, and the pressing rod 3 will slide down at this time. The clamping block 6 and the pressing rod 3 are arranged between the driving roller 9 and the driven roller 10, and the supporting frame 2 is slidably connected to the side wall of the pinch mechanism, and the pressing rod 3 is slidably connected, and the supporting frame 2 is provided with a pressure sensor. 4. The upper surface of the support frame 2 is fixedly connected with a soft rubber pad, and the soft rubber pad and the pressure sensor 4 are arranged under the pressure rod 3. The pressure rod 3 cooperates with the pressure sensor 4 and can enter the driving roller 9 at the end of the yarn. After being between the driven roller 10 and the driven roller 10, the pressure rod 3 uses its own weight to trigger the pressure sensor 4, and then the pressure sensor 4 controls the operation of the pneumatic push rod 5 and the pause of the hosiery machine. The purpose of setting the soft rubber pad is to clamp the yarn. end, and prevent the pressure rod 3 from continuing to drive the yarn to move under the action of its own inertia (during the operation of the yarn feeding mechanism, the pressure rod 3 will rotate with the movement of the yarn), so that the clamping block 6 cannot clamp the yarn. Line, a pneumatic push rod 5 is fixedly connected on the support frame 2. In the textile production process, an air compressor needs to be set to drive some equipment, so the pneumatic push rod 5 is used to drive the clamping block 6. Of course, the pneumatic push rod The rod 5 can also be replaced by an electric push rod, and the driving end of the pneumatic push rod 5 is slidably connected with two clamping blocks 6. The side wall of the support frame 2 close to the clamping block 6 is provided with a guide groove 7, and the guide groove 7 is arranged in the guide groove 7. A slider is slidably connected, and the slider is fixedly connected with the clamp block 6. After the pneumatic push rod 5 drives the clamp block 6 to move, the guide groove 7 is used to cooperate with the slider to control the movement track of the clamp block 6, so that the clamp block 6 is moved. The yarn can be clamped and sent to the knotter 8, and then the end of the yarn and the head end of the next roll of yarn can be knotted and fixed into one yarn by the knotter 8, so as to achieve the purpose of uninterrupted feeding. A knotter 8 is also installed on the support frame 2 , the driven roller 10 is rotatably connected to the support frame 2 through a damping shaft, and the driving roller 9 and the driven roller 10 are provided with an inverted end near the knotter 8 . The chamfering is used to drive the yarn back to the initial position again after the knotting is completed, and ensure that the yarn can be clamped into the pinch mechanism. In this design, the user runs the yarn feeding mechanism. During the process, after the next roll of yarn to be used is placed on the pay-off frame 1, the first end of the yarn to be used can be inserted into the knotter 8. After the previous roll of yarn is used up, it can be used The knotting machine 8 is automatically wired, so as to achieve the effect of uninterrupted yarn feeding, no need for secondary threading, and no need for yarn replacement. The timing requirement is low, and the operation of replacing the bobbin can be completed at any time before the second roll of yarn is used up, which greatly facilitates the user's operation, and the entire yarn feeding mechanism is only required during the operation of the knotter 8. Stopping the hosiery machine greatly reduces the downtime of the hosiery machine and improves the production efficiency.

The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Equivalent replacement or modification of the new technical solution and its utility model concept shall be included within the protection scope of the present utility model.
