Description

Technical Field

[0001] The invention relates to the technical field of optical cable manufacturing, and in particular to an automatic grease weighing system and method. Background Art

[0002] The stranded optical cable is usually composed of a cable core, a sheath and a protective layer. The cable core is located in the center of the cable. The cable core contains a loose tube, and the loose tube contains optical fiber or optical fiber ribbon.

[0003] As we all know, water-blocking performance is an important performance indicator of optical cables. Moisture and water entering the optical cable may cause great damage to the optical fiber loss characteristics and static fatigue performance. At low temperatures, the optical fiber may break due to the freezing of water in the cable core, and water may corrode the metal body in the cable, which will damage the life of the optical cable.

[0004] Most manufacturers use the method of filling the cable core with optical cable jelly to block water longitudinally. During the cabling process, a jelly barrel is placed to apply jelly. If there is too much jelly in the existing jelly barrel, it will overflow to the ground, polluting the working environment. If there is too little jelly, no jelly will be applied and the cable core will seep water. Summary of the invention

[0005] The main technical problem solved by the present invention is to provide an automatic weighing system and method for grease, which can automatically replenish the grease online and automatically add grease to the cable core, thereby preventing the grease from overflowing and wasting when there is too much grease, polluting the working environment, and preventing the grease from being unable to be dispensed when there is too little grease, avoiding water seepage in the cable core, and reducing the workload of workers.

[0040] Furthermore, the automatic grease weighing system also includes a weighing control unit, which includes a weighing sensor 5 and a weight PLC controller 12 , and the weight PLC controller 12 is electrically connected to the diaphragm pump 3 and the weighing sensor 5 , respectively.

[0041] Specifically, the weighing sensor 5 is arranged on the frames on the left and right sides of the oil paste storage box 4.

[0045] Embodiment 2

[0046] An automatic ointment weighing method, using the automatic ointment weighing system in the first embodiment, includes the following control steps:

[0047] S1. When the weight of the paste in the paste storage box 4 changes, the weighing sensor 5 promptly senses the weight change on both sides of the paste storage box 4, and then converts it into an analog quantity through the weighing module transmitter 13 and outputs it to the weight PLC controller 12 inside the electric control box 8.
