1-3, an embodiment of the present invention provides a method for processing a water meter cable, which is applied to a processing device for a water meter cable. The processing device for the water meter cable includes a stranding device and an injection molding device. The stranding device includes a core twisting machine, a shield twisting machine and a pair twisting machine. The processing method for the water meter cable includes:

S101, using the core twisting machine to twist a plurality of tinned copper wires into a water meter cable core 5 of a first pitch;

S102, injecting the insulating layer 4 into the water meter cable core 5 through the injection molding device to obtain a water meter insulating cable core;

S103, using the twisting machine to simultaneously twist the plurality of water meter insulating cable cores, the plurality of water blocking yarns 6 and the water blocking tape 308 into a water meter secondary cable, wherein the water blocking tape 308 wraps the water meter insulating cable cores and the water blocking yarns 6;

S104, using the shield twisting machine to twist the shielding layer 2 of the water meter secondary cable to obtain a water meter shielded cable;

S105, injecting the sheath layer 1 on the water meter shielded cable through the injection molding device to obtain a water meter cable.

Specifically, the tinned copper wire of the embodiment of the present invention adopts tinned copper wire of Class 5 conductor (tinning can effectively prevent the copper wire from oxidation and blackening in high temperature and humidity, and improve solderability, reliability and heat resistance), which is not limited here. A plurality of tinned copper wires are twisted into a water meter cable core 5 of a first pitch by a core twisting machine. The first pitch is set according to specific needs. The first pitch is obtained by adjusting the twisting speed and forward speed of the tinned copper wire by the core twisting machine. The specific first distance is not limited here. Then, the water meter cable core 5 is injection molded with an insulating layer 4 by an injection molding mechanism to obtain a water meter insulating cable core. The insulating material can be high-density polyethylene HDPE, which is not limited in detail; by injection molding the insulating layer 4, the risk of wear and damage due to non-external forces and irresistible factors is reduced in terms of the mechanical strength of the cable, and the problem of its easy immersion in water is also effectively solved. It effectively protects other cable accessories associated with it and improves the power supply reliability of the entire transmission system. The water-blocking tape 308, multiple water meter insulation cable cores and multiple water-blocking yarns 6 are twisted into water meter cables by a twisting machine at the same time. Multiple water meter insulation cable cores are twisted into pairs (the twisting pitch is not greater than 8 times the outer diameter of the twisting), and the gaps between the pairs are tightly filled with water-blocking yarns 6, and a layer of double-sided insulating water-blocking tape 308 is overlapped and wrapped on the outside of the water meter insulation cable core and the water-blocking yarn 6, with an overlapping coverage rate of not less than 30%. The water-blocking tape 308 contains a preservative. After using the water-blocking tape 308, the various cable components can effectively block water, while protecting the safe use of the cable and increasing its service life. The shielding layer 2 of the water meter secondary cable is twisted by a shielding twisting machine to obtain a water meter shielded cable. The shielding layer 2 is wrapped with a double-sided plastic-coated copper tape (copper wire, etc. can also be used, and the specific details are not limited), and the overlapping coverage rate is not less than 25%. It effectively suppresses noise, crosstalk, data packet loss and other phenomena between cables caused by electromagnetic interference, thereby improving the stability of water meter cable transmission services. Block the electromagnetic radiation generated by high-frequency signals in the water meter cable, block the leakage of electromagnetic signals, and avoid coupling the carried electromagnetic signals to adjacent cables in the same weak current channel to cause information leakage. Finally, the water meter cable is obtained by injection molding the sheath layer 1 of the water meter shielding cable through an injection molding mechanism. The material of the sheath layer 1 is low-density polyethylene LDPE, so that the water meter cable has: high strength, high wear resistance, not easy to be mechanically damaged; high cold resistance, not easy to cause low-temperature brittle cracking when laid outdoors in high-cold areas; excellent environmental stress cracking resistance (ESCR), ensuring that in the use environment, its sheath layer 1 will not be eroded by surfactants and cracked on the surface, thereby reducing the service life; excellent oxidation resistance, slowing down the light and heat aging of the outer sheath in high temperature environment; halogen-free and non-toxic, ensuring the health and safety of drinking water.

The embodiment of the present invention adopts a high-speed servo motor 100 and a high-precision bearing seat, which can greatly improve the efficiency of stranding, and has high working stability and good stranding quality. When the first pitch needs to be adjusted, it is only necessary to select a pulley with a corresponding number of teeth according to the required first pitch, and then match it with a second take-up wheel 107 of different diameters, so as to further expand its pitch adjustment range, with fast adjustment speed, flexible matching, time-saving and labor-saving, effectively saving a lot of time and manpower, and high working efficiency, which not only shortens the entire production cycle, but also improves the quality of stranding and reduces production costs.
