DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Please refer to Figures 1-4 The rotary tension guide yarn assembly of the composite coated wire provides one technical scheme:

[0024] The first embodiment: including support 1, support 1 is provided with tension fine adjustment assembly 2, tension fine adjustment assembly 2 and the right side of support 1 are provided with wear-resistant guide wheel assembly 4;

[0025] The tension adjustment component 2 includes a slide groove 21 on the bracket 1. A rotating seat 22 is slidably connected to the inner surface of the slide groove 21. A detachable detection component 3 is installed inside the rotating seat 22. Two fixed seats 23 are fixedly connected to the left side of the slide groove 21. A lead screw 24 is rotatably connected between the opposite sides of the two fixed seats 23. The rotating seat 22 is threadedly connected to the surface of the lead screw 24 through a connecting block. The detachable detection component 3 detects the pressure on the wear-resistant guide wheel assembly 4 through a pressure sensor 34 and adjusts the tension of the covering wire through the lead screw 24. A drive motor 25 is fixedly connected to the top of the upper fixed seat 23. The output end of the drive motor 25 is fixedly connected to one end of the fixed seat 23. A controller 26 is fixedly installed on the drive motor 25. The pressure sensor 34 is wirelessly connected to the controller 26.

[0026] The detachable detection component 3 includes a mounting groove 31 at the bottom of the rotating seat 22. The top of the inner wall of the mounting groove 31 has two threaded holes and a groove 32, and the threaded holes and the groove 32 are concentric. A mounting block 33 is inserted into the inside of the mounting groove 31. A pressure sensor 34 is embedded in the mounting block 33. The mounting block 33 is fixed inside the mounting groove 31 by two hexagonal socket head cap screws 35. A return spring 36 is sleeved on the surface of the hexagonal socket head cap screws 35 located in the groove 32.

[0027] The covering yarn passes over the guide wheel and the pressure is detected by the pressure sensor 34. When the pressure decreases, the tension of the covering yarn is precisely adjusted by rotating the lead screw 24, which improves the practicality of the device.

[0028] The second embodiment differs from the first embodiment in that: the wear-resistant guide wheel assembly 4 includes a rotating rod 41, which is rotatably connected to the lead screw 24. A fixed wheel 42 is fixedly connected to the surface of the rotating rod 41. A ceramic sleeve 43 is sleeved on the outside of the fixed wheel 42. Multiple positioning strips 44 are fixedly connected at equal intervals on the surface of the fixed wheel 42. Multiple positioning grooves that cooperate with the positioning strips 44 are opened on the inner surface of the ceramic sleeve 43. A pressure plate 45 is sleeved on the surface of the rotating rod 41. A locking bolt 46 is threadedly connected to the surface of the rotating rod 41. The locking bolt 46 is tightened to press the pressure plate 45 to one side of the fixed wheel 42 and the ceramic sleeve 43.

[0029] The guide wheel in the wear-resistant guide wheel assembly 4 is covered with a ceramic sleeve, which increases the wear resistance of the guide wheel. The ceramic sleeve can be disassembled for easy replacement, which is beneficial to the long-term use of the guide assembly.

[0030] In use, the composite coated yarn is passed around from below the lower wear-resistant guide wheel assembly 4 and from above the upper wear-resistant guide wheel assembly 4. The coated yarn presses against the upper wear-resistant guide wheel assembly 4, and the pressure sensor 34 detects the pressure on the wear-resistant guide wheel assembly 4. When the coated yarn moves, if the pressure sensor 34 detects a decrease in pressure, the pressure sensor 34 transmits a signal to the controller 26, and the controller 26 controls the drive motor 25 to start. The drive motor 25 starts and causes the lead screw 24 to rotate. The rotation of the lead screw 24 causes the wear-resistant guide wheel assembly 4 to move upward, thereby increasing the tension of the coated yarn. In addition, when the ceramic sleeve 43 is severely worn after long-term use, the locking bolt 46 is unscrewed and the pressure plate 45 is removed. At this time, the ceramic sleeve 43 can be removed and replaced.
