Description

Technical Field

[0001] This utility model relates to the field of air-coated yarn machines, and more specifically to a yarn transport mechanism for an air-coated yarn machine. Background Technology

[0002] The existing yarn transport mechanism of air-covered yarn machines can only achieve simple yarn transport and cannot adjust the yarn tension. Moreover, its transport mechanism is relatively rigid and the yarn feeder cannot be adjusted. Summary of the Invention

[0003] This utility model aims to provide a yarn transport mechanism for an air-coated yarn machine, the specific solution of which is as follows:

[0004] A yarn transmission mechanism for an air-coated yarn machine includes a frame, a support rod on the frame, and a plurality of transmission components on the support rod. Each transmission component includes a rotating arm and a central shaft. The rotating arm is rotatably connected to the support rod, and the central shaft is mounted on the frame. The rotating arm has a first rotating wheel and a second rotating wheel, and a belt is provided between the first rotating wheel and the second rotating wheel. A motor is mounted on the rotating arm, and the first rotating wheel is driven to rotate by the motor. The belt and the central shaft are configured to cooperate with each other.

[0005] There are two conveying components, and the two conveying components are in opposite directions. This arrangement is for better tensioning of the yarn.

[0006] The conveying assembly includes a sliding clamp that is slidably mounted on a support rod, and a rotating arm that is rotatably mounted at the other end of the sliding clamp. This design allows the conveying assembly to move along the support rod, thereby adjusting its position.

[0007] The frame is equipped with a crossbar, and a yarn holder is mounted on the crossbar. A yarn feeder is rotatably connected to the yarn holder. That is, the yarn feeder can also rotate for adjustment.

[0008] The crossbars are in two sets, one above and one below the conveying assembly.

[0009] This utility model discloses a yarn transmission mechanism for an air-coated yarn machine. The yarn passes between the belt and the intermediate shaft, or along the outside of the belt (the side facing away from the intermediate shaft). The rotating arm is rotatably connected to the support rod. When the yarn passes between the belt and the intermediate shaft, the pressure received by the yarn can be adjusted by rotating the rotating arm. When the yarn passes through the outside of the belt, the tension of the yarn can be adjusted by rotating the rotating arm. Attached Figure Description

[0015] The following is combined Figure 1-4 Further explanation:

[0016] A yarn transmission mechanism for an air-coated yarn machine includes a frame 1, a support rod 2 on the frame 1, and several transmission components 3 on the support rod 2. Each transmission component 3 includes a rotating arm 4 and a central shaft 5. The rotating arm 4 is rotatably connected to the support rod 2, and the central shaft 5 is mounted on the frame 1. The rotating arm 4 has a first rotating wheel 7 and a second rotating wheel 8, and a belt 9 is provided between the first rotating wheel 7 and the second rotating wheel 8. The rotating arm 4 has a motor 10, and the first rotating wheel 7 is driven to rotate by the motor 10. The belt 9 and the central shaft 5 are configured to cooperate with each other.

[0017] There are two conveying components 3, and the two conveying components 3 face opposite directions. This arrangement is for better tensioning of the yarn.

[0018] The conveying assembly 3 includes a sliding clamp 11, which is slidably mounted on the support rod 2, and a rotating arm 4 is rotatably mounted on the other end of the sliding clamp 11. This design allows the conveying assembly 3 to move on the support rod 2, thereby adjusting its position.

[0019] The frame 1 is equipped with a crossbar 12, and a yarn holder 13 is mounted on the crossbar 12. A yarn feeder 6 is rotatably connected to the yarn holder 13. That is, the yarn feeder 6 can also rotate, thereby allowing for adjustment.

[0020] The crossbars 12 are in two sets, located above and below the conveying assembly 3 respectively.

[0021] In this embodiment, there are two conveying components 3. When the yarn passes through the outside of the belt 9 in the upper conveying component 3, the tension of the yarn can be adjusted by rotating the rotating arm 4. When the yarn passes through the belt 9 and the central shaft 5 in the lower conveying component 3, the pressure received by the yarn can be adjusted by rotating the rotating arm 4. With this design, the lower conveying component 3 can clamp the yarn, while the upper conveying component 3 can better tension the yarn (because in reality, the yarn is conveyed from the bottom to the top).

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
