[0019] 3. By using a hysteresis clutch that can adjust the torque in real time on the wrapping machine to control the winding tension, it is ensured that the positions of the core wire and the ground wire do not change during high-speed wrapping, and the tension of the wrapping tape is kept stable during high-speed wrapping, ensuring that the pitch of the wrapping tape is stable and the tightness is consistent, thereby making the cable performance more stable.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-2 , FIG. 1 is a preferred embodiment of the present invention, a taping head for a taping machine, comprising a taping machine body, the taping machine body being provided with a material changing mechanism and a fixing mechanism;

[0025] The material changing mechanism includes two groups of tape guide arms 12, one end of each group of tape guide arms 12 is rotatably connected to a movable arm 13, a tape guide arm spring 15 is provided at the outer wall between the tape guide arm 12 and the movable arm 13, both ends of the tape guide arm spring 15 are respectively fixedly mounted on the outer walls of the tape guide arm 12 and the movable arm 13, a material tape guide wheel 16 is provided on the inner side of the tape guide arm 12 and the movable arm 13, and the material tape guide wheel 16 is mounted on the inner side of the tape guide arm 12 and the movable arm 13 through a movable pin 14;

[0026] The material changing mechanism also includes a wrapping head material tape seat 6, one end of which is movably mounted with a material tray slot 7, and a support spring is arranged at the lower end of the material tray slot 7;

[0027] The fixing mechanism comprises a wrapping threading tube 18 , the outer wall of which is provided with a material discharge groove and a material threading seam. The wrapping threading tube 18 is a hollow metal tube, and a wrapping guide rod 17 is arranged at one end of the wrapping threading tube 18 .

[0028] Specifically, the main body of the wrapping machine includes a hollow main shaft 1, and a tensioner mounting seat 5 is arranged on the outer side of the hollow main shaft 1. An over-current slip ring 2 and an over-current carbon brush 3 are installed at one end of the tensioner mounting seat 5. The over-current slip ring 2 and the over-current carbon brush 3 provide a power supply with adjustable tension for the hysteresis clutch 4. During the wrapping process, the suction force between the inner and outer rings of the hysteresis clutch 4 can be adjusted according to the cable process requirements and the real-time tape tension changes, thereby achieving the purpose of adjusting the tape tension.

[0029] Among them, a hysteresis clutch 4 is arranged on the inner side of the tensioner mounting seat 5, and the winding head assembly disk 8 is installed on the outer ring of the hysteresis clutch 4 through the tensioner mounting seat 5. A winding head tape seat 6 and a rotating disc 9 are installed on one side of the hysteresis clutch 4. The winding head assembly disk 8 is fixed on the hollow main shaft 1, and the rotating disc 9 and the winding head tape seat 6 are connected to the inner ring of the hysteresis clutch 4. A tape arc guide wheel is also installed on the outer side of the winding head tape seat 6.

[0030] It can be understood that a rolling guide rod 10 and a double-sided material tape guide arm 11 are fixedly mounted on one end of the wrapping head material tape seat 6 , and a tape guide arm 12 is fixedly mounted on one end of the double-sided material tape guide arm 11 .

[0031] In the prior art, since high-frequency data lines have very strict shielding requirements for aluminum foil or copper foil, unstable tension in any link during the wrapping process will cause fluctuations in the wrapping pitch and changes in the relative positions of the core wire and the ground wire. In addition, the wrapping tape will float up due to wind resistance when rotating at high speed, resulting in unstable pitch of the wrapping tape after wrapping and inconsistent tightness, thereby affecting the transmission performance of the high-frequency data line.

[0032] The present invention controls the winding tension by adopting a hysteresis clutch 4 which can adjust the torque in real time on the wrapping machine, thereby ensuring that the positions of the core wire and the ground wire do not change during high-speed wrapping, and maintaining the tension of the wrapping tape stable during high-speed wrapping, ensuring that the pitch of the wrapping tape is stable and the tightness is consistent, thereby making the cable performance more stable.

[0033] It should be added that, in the present embodiment, the winding threading tube 18 is made of a hollow metal tube with a length of 150mm-250mm, the outer diameter of the threading tube is 10-20mm, and the inner wall diameter is 5-10mm; a 50-100mm long material discharge trough is opened at the front for manual wrapping; a 50-100mm long material threading seam is opened on the back to fix the position of the wrapping tape and the wire during wrapping; it is assembled with the winding head main shaft through a welded connecting sleeve.

[0034] It should be noted that, in the figure, the function of the hollow spindle 1 is to transmit the motor power to the winding head assembly disk, the wire passes through the spindle to reach the winding threading tube 18, the function of the over-current slip ring 2 is to supply power to the hysteresis clutch during rotation, the function of the over-current carbon brush 3 is fixedly installed, and supplies power to the over-current slip ring 2 during rotation, and the function of the hysteresis clutch 4 is to change the magnetic force between the inner ring (material disk) and the outer ring (winding head assembly disk 8) through an adjustable voltage. The change in magnetic force will change the relative speed of the spindle and the material disk, thereby changing the tension of the material strip at the winding point. When the magnetic force is maximum, the spindle and the material disk are basically synchronized, and the function of the tensioner mounting seat 5 is to connect the spindle and the outer ring of the hysteresis clutch 4 and the winding The head assembly disk 8, the winding head material tape seat 6 is used to install the material tape disk, the material tape slot 7 is used to prevent the material tape disk from sliding out, and the material disk can be quickly changed. The winding head assembly disk 8 is used to install the rolling guide rod 10 and the material tape guide arm 11 and the movable arm 13 components. The rotating faceplate 9 is used to connect the winding head material tape seat 6 and the inner ring of the hysteresis clutch 4. The rolling guide rod 10, the double-sided material tape guide arm 11, the material tape guide wheel 16, and the winding guide rod 17 are used for guiding the material tape. When the material tape is processed, the moving path is the material disk, the rolling guide rod 10, the double-sided material tape guide arm 11, the guide arm 12, the movable arm 13, the material tape guide wheel 16, the winding guide rod 17, and the winding threading tube 18 in sequence.
