Description

Technical Field

[0001] The invention relates to the field of cable manufacturing, and in particular to a multi-layer winding integrated taping machine. Background Art

[0002] The wrapping machine is used for wrapping the insulating core wires of electric wires, power cables, control cables, optical cables, etc. It is divided into single-layer, double-layer and triple-layer wrapping. The wrapping tape made of mica tape, cotton paper tape, aluminum foil, polyester film, etc. is rotated on the turntable and wrapped on the core wire. It is mainly used for wrapping the insulating core wires of electric wires, power cables, control cables, optical cables, etc.

[0003] At present, the longitudinal double-layer integrated taping machine has very strict shielding requirements for aluminum foil or copper foil for high-frequency data cables. Unstable tension in any link during the taping process will cause fluctuations in the taping pitch and changes in the relative positions of the core wire and the ground wire. In addition, the tape will float up due to wind resistance when rotating at high speed, resulting in unstable pitch and inconsistent tightness after taping, which affects the transmission performance of high-frequency data cables. For this reason, we propose a multi-layer winding integrated taping machine. Summary of the invention

[0004] The object of the present invention is to provide a multi-layer winding integrated taping machine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, a multi-layer winding integrated taping machine includes a multi-head power pay-off device, a first wrapping machine, a wire crimping die, a second wrapping machine, a coding device, a third wrapping machine, a heating duct oven, a cold air gun, a cable diameter gauge, a traction machine and a shaft row take-up device, which are sequentially arranged along the forward direction of the cable, and a tension adjustment device is arranged in the multi-head power pay-off device;

[0006] A multi-head power pay-off device, which is used as a sensor to detect the pay-off tension;

[0007] The tension regulating device uses the pay-off tension data detected by the multi-head power pay-off device to control and adjust the winding tension during pay-off.

[0008] The multi-head power pay-off device is provided with a core wire tension detection sensor and a real-time tension digital display in sequence along the threading direction. The tension detection sensor and the real-time tension digital display form a tension control closed loop with the counterweight on the tension adjustment device.

[0009] The tension adjustment device includes a counterweight, a balance bar and a guide wheel. One end of the balance bar is rotatably connected to the multi-head power pay-off device, the outer surface of the balance bar is slidably connected with the counterweight, and the other end of the balance bar is provided with a guide wheel.

[0010] Further: the first wrapping machine, the second wrapping machine and the third wrapping machine are provided with a wrapping head, and the wrapping head includes a hollow main shaft, a power-receiving slip ring, a power-receiving carbon brush, a hysteresis controller and a hysteresis clutch, a clutch mounting seat, a wrapping head material seat, a wrapping head assembly disk, a rotating faceplate, a rolling guide rod, a double-sided material guide arm, a double-sided material guide arm, and a material arc guide wheel. The power-receiving slip ring and the power-receiving carbon brush provide a power supply with adjustable tension for the hysteresis clutch.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In the present invention, the pay-off tension is controlled by a sensor and a tension adjustment device on the pay-off device, and at the same time, a hysteresis clutch capable of adjusting the torque in real time is used on the wrapping machine to control the winding tension, thereby ensuring that the positions of the core wire and the ground wire do not change during high-speed wrapping, and maintaining a stable tension of the wrapping tape during high-speed wrapping, thereby ensuring a stable pitch of the wrapping tape and consistent tightness, thereby making the cable performance more stable.

DETAILED DESCRIPTION

[0016] 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.

[0017] See also Figure 1-2 , the figure shows a preferred embodiment of the present invention, including a multi-head power pay-off device 1, a first wrapping machine 3, a crimping die 4, a second wrapping machine 5, a coding device 6, a third wrapping machine 7, a heating duct oven 8, a cold air gun 9, a cable diameter gauge 10, a traction machine 11 and a shaft row take-up device 12, which are arranged in sequence along the forward direction of the cable. A tension adjusting device 2 is provided in the multi-head power pay-off device 1;

[0018] A multi-head power pay-off device 1 is provided with a core wire tension detection sensor 13 and a real-time tension digital display 14 in sequence along the threading direction. The tension detection sensor 13 and the real-time tension digital display 14 form a tension control closed loop with a counterweight 15 on the tension adjustment device 2;

[0019] The tension adjustment device 2 includes a counterweight 15, a balance rod 36 and a guide wheel 37. One end of the balance rod 36 is rotatably connected to the multi-head power line-releasing device 1, the outer surface of the balance rod 36 is slidably connected to the counterweight 15, and the other end of the balance rod 36 is provided with a guide wheel 37.

[0020] Among them, the first wrapping machine 3, the second wrapping machine 5 and the third wrapping machine 7 are provided with a wrapping head, which includes a hollow main shaft 21, a power-receiving slip ring 22, a power-receiving carbon brush 23, a hysteresis controller 24 and a hysteresis clutch 25, a clutch mounting seat 26, a wrapping head tape seat 27, a wrapping head assembly disk 28, a rotating disc 29, a rolling guide rod 30, a double-sided tape guide arm 31, a double-sided tape guide arm 32, and a tape arc guide wheel 33. The power-receiving slip ring 22 and the power-receiving carbon brush 23 provide a power supply with adjustable tension for the hysteresis clutch 25.

[0021] In this embodiment, the winding head assembly disk 28 is installed on one side of the hollow main shaft 21, and the powered slip ring 22 and the powered carbon brush 23 provide a power supply with adjustable tension for the hysteresis clutch 25. The tension detection sensor 13 and the real-time tension digital display 14 and the counterweight 15 on the tension adjustment device 2 form a tension control closed loop. During the winding process, the suction force between the inner and outer rings of the hysteresis clutch 25 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.

[0022] It should be added that, in the present embodiment, the wrapping threading tube (not shown in the figure) used by the wrapping machine 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 wrapping head main shaft through a welded connecting sleeve.

[0023] Working principle: Place multiple core wire reels 34 or ground wire reels on the corresponding multi-head power pay-off shaft 35. When the wire passes through the guide wheel 37, the position of the counterweight 15 on the balance bar 36 can be manually adjusted, and then the guide wheel 37 is used to apply pressure to the wire to adjust the tension on the wire. At the same time, the tension is detected in real time by the tension detection sensor 13 and the real-time tension digital display 14 and the value is displayed. When each wire passes through the last guide wheel of the pay-off machine, it is gathered into strands and then enters the first wrapping machine 3 for the first wrapping, usually shielding materials such as aluminum foil or copper foil. The wrapping method is also divided into longitudinal wrapping or wrapping. After the wrapping is completed, the wire passes through the wire pressing mold 4 and enters the second wrapping machine 5 to wrap the Mylar or other insulating tape materials around the shielded wire. After the second wrapping is completed, the wire passes through the coding device 6 (Printer Mx1Pro) prints the words and marks according to customer requirements, and then enters the third wrapping machine 7 to wrap the wire again to achieve the purpose of strengthening the linear structure. After the third wrapping, the wire enters the heating duct oven 8 for heat shrinkage and drying to obtain the finished wire. Then the cable diameter gauge 10 (LST-25 / JIIB) performs real-time detection of the outer diameter parameters of the finished wire to see if they meet the appearance requirements. The traction machine 11 is composed of a traction wheel and a belt driven by a motor, which effectively ensures that the number of bending times of the wire is minimized during the traction process. Finally, the shaft-arranged wire-taking device 12 uses a servo-driven wire-taking shaft and an electric slide to achieve precise control of the wire-taking drum width and spacing.
