Description

Technical Field

[0001] This application relates to the technical field of oiling machines, and more specifically, to an immersion oiling machine. Background Technology

[0002] Cables, including optical cables and electrical cables, often require the application of lubricating oil or grease to their surfaces during production, installation, or operation. The main purpose of lubrication is to reduce frictional resistance between the cable and other components, facilitating cable threading, and also providing some protection against moisture, corrosion, and sealing.

[0003] Currently, the most common cable oiling equipment in the industry mainly adopts the following two technical solutions:

[0004] Contact coating method: This method typically uses an oil roller or oil brush structure. As the cable passes through, it comes into contact with the oil roller or oil brush immersed in oil, thereby carrying the lubricant to its surface. The main drawbacks of this method are: poor oil uniformity, difficulty in precisely controlling the oil film thickness, and easy occurrence of too much or too little oil; poor coating effect for irregular or thin cables; and long-term contact and friction between the oil roller or oil brush and the cable can easily generate wear debris, contaminating the oil and cable surface.

[0005] Non-contact dripping oil method: This method uses a pump to drip or spray lubricating oil onto the cables it passes over. While this reduces contact wear on the cables, it still has significant drawbacks: a large amount of oil drips off due to ineffective adhesion, causing environmental pollution; uneven oiling also exists, with oil accumulating at the bottom of the cable while the top is insufficient; more importantly, the oil film on the cable surface after oiling is thick and oil droplets remain, making it impossible to proceed with subsequent processes immediately, requiring a long time to stand and drain, which seriously affects production efficiency.

[0006] Therefore, existing cable oiling equipment suffers from technical problems such as uneven oil application, significant lubricant waste, and low production efficiency. A new type of cable oiling machine is urgently needed. Utility Model Content

[0007] To address the problems of uneven oiling and low production efficiency in existing cable oiling equipment, this application provides an immersion oiling machine.

[0008] An immersion oiling machine includes a housing with a working chamber inside. The working chamber is divided by a partition into an oiling chamber for holding oil and an oil return chamber for treating residual oil. The housing has a first perforation on the wall of the oiling chamber and a second perforation on the wall of the oil return chamber. The partition has a third perforation. The centers of the first, second, and third perforations are on the same straight line to allow cables to pass through. A blower is installed inside the housing. The blower has an output pipe connected to its output end and an input pipe connected to its input end. The output pipe passes through the oil return chamber, with its opening aligned with the movement path of the cable for blowing air onto the cable. The input pipe also passes through the oil return chamber for drawing in oil from the oil return chamber and drawing in air to supply the blower.

[0009] Preferably, a first mesh box is installed on the partition, and a first sponge is installed inside the first mesh box. A first baffle is provided near the first perforation in the oil passage cavity. A second mesh box is provided on the side of the first baffle away from the partition, and a second sponge is installed inside the second mesh box. A second baffle is provided near the second perforation in the oil return cavity. A third mesh box is provided on the side of the second baffle away from the partition, and a third sponge is installed inside the third mesh box. The first sponge, the second sponge, and the third sponge are all provided with through holes for cables to pass through. The through holes are configured to control the thickness of the lubricating oil on the cable surface.

[0010] Preferably, an air inlet is provided on the wall of the oil return chamber, and an air inlet valve is provided at the air inlet to control the air intake to balance the air pressure in the oil return chamber.

[0011] Preferably, the input pipe is integrated with a filter assembly for filtering oil.

[0012] Preferably, the filter assembly includes a sealed cabinet fixed to the input pipe, the sealed cabinet dividing the input pipe into a first pipe segment and a second pipe segment, and a filter element for filtering oil is detachably disposed in the sealed cabinet between the first pipe segment and the second pipe segment of the input pipe.

[0013] Preferably, the sealing cabinet includes a cabinet body and a sealing plate. An opening is provided on one side of the cabinet body, and the sealing plate is fixed to the cabinet body with bolts to close the opening. Two spaced plates are provided on each of the opposite side walls inside the cabinet body. The two plates are located between the first and second pipe sections of the input pipe, and a slot is formed between the two plates. The opposite sides of the filter element are respectively inserted into the two slots to fix the filter element.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. By setting up an oil-filled chamber to completely immerse and coat the cable with oil, a uniform coating without dead angles is achieved in the circumferential direction, solving the problem of uneven coating caused by dripping or contact methods. The blower is equipped with an output pipe, whose orifice is aimed at the cable and blows air. The blowing action dries the cable after it leaves the oil-filled chamber, shortening or eliminating the settling and drying time, allowing the cable to immediately enter subsequent processes, significantly improving production efficiency. An input pipe is set at the blower's input end, which draws in the atomized or dripping oil in the return oil chamber for oil recovery, maintaining a dry environment in the return oil chamber and facilitating cable drying. At the same time, the output and input pipes are connected to the same chamber, forming a highly efficient, localized air and oil circulation loop. This loop allows the oil mist formed by the airflow from the output pipe and the oil to be recovered, reducing oil waste and pollution to the external environment, resulting in a cleaner working environment.

[0016] 2. Excess oil on the cable is scraped off by the sponge, and the amount of oil falling out of the casing through the perforation is reduced, so that the oil film thickness on the cable meets the requirements and the pollution of the external environment is reduced.

[0017] 3. Because the blower continuously draws air from the return oil chamber through the input pipe, the air pressure inside the chamber will decrease. Installing an air inlet valve allows for precise control of the amount of fresh air entering the return oil chamber. This prevents excessive negative pressure from forming inside the chamber, ensuring that the oil can flow smoothly back to the return oil chamber. It also guarantees a stable and sufficient air supply for the blower, making the airflow purging effect consistently reliable, and resulting in a more stable and efficient operation of the entire internal air-oil circulation system.

[0018] 4. The oil entering the input pipe is filtered through the filter assembly, achieving gas-liquid separation and preventing oil from entering the blower and causing damage. Simultaneously, the oil is recovered on the filter assembly. Furthermore, the design of the cabinet and sealing plate allows for filter element removal, facilitating filter element replacement, and the oil adhering to the filter element enables oil recovery.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Reference Figure 1 and Figure 2 An immersion oiling machine includes a housing 1. Inside the housing 1 is a working chamber, which is divided into an oiling chamber 3 and an oil return chamber 4 by a partition 2. The oiling chamber 3 is used to hold oil and immerse cables in the coating process, while the oil return chamber 4 is used to remove excess oil and dry the cables. The housing 1 has a first through-hole 11 on the wall of the oiling chamber 3 for the cable to enter, and a second through-hole 12 on the wall of the oil return chamber 4 for the cable to exit. The partition 2 has a third through-hole 21 for the cable to pass through. The centers of these three through-holes are on the same straight line, forming a through-channel for the cable.

[0026] Reference Figure 2 Inside the housing 1, there is a blower 5. The output end of the blower 5 is connected to an output pipe 51, and its input end is connected to an input pipe 52. The output pipe 51 passes through the oil return chamber 4, with its orifice facing the moving path of the cable, and is used to blow high-speed airflow onto the surface of the cable to dry the oil on the cable surface. The input pipe 52 also passes through the oil return chamber 4, and is used to simultaneously draw in the atomized oil and air in the oil return chamber 4, and deliver the mixed gas and liquid to the blower 5, realizing the recovery of oil and the supply of air.

[0027] Reference Figure 1A first mesh box 6 is installed on the side of the partition 2 facing the oil passage cavity 3, and a first sponge 61 is embedded inside it. A first baffle 7 is provided in the oil passage cavity 3 near the first perforation 11, and a second mesh box 8171 is installed on the side of the baffle away from the partition 2, in which a second sponge 711 is embedded. A second baffle 8 is provided in the oil return cavity 4 near the second perforation 12, and a third mesh box is installed on the side of the baffle away from the partition 2, in which a third sponge 811 is embedded. The first sponge 61, the second sponge 711 and the third sponge 811 are all provided with through holes for cables to pass through. These through holes are configured to scrape off excess lubricating oil from the surface of the cable, thereby controlling the thickness of the oil film on the surface of the cable and effectively preventing oil leakage from the through holes.

[0028] Reference Figure 4 The housing 1 also has an air inlet 13 on the cavity wall of the oil return chamber 4, and an adjustable air inlet valve 14 is provided at the air inlet 13. The air inlet valve 14 is existing technology and will not be described in detail in this application. The amount of fresh air entering the oil return chamber 4 is controlled by the cooperation of the air inlet 13 and the air inlet valve 14 to balance the negative pressure generated by the blower 5, ensure the stability of the air pressure in the oil return chamber 4, and ensure the stable supply of air source to the blower 5.

[0029] Reference Figure 2 and Figure 3 The input pipe 52 integrates a filter assembly 9, which includes a sealed cabinet 91 fixed to the input pipe 52. This cabinet divides the input pipe 52 into a first pipe section 511 and a second pipe section 512. The first pipe end passes through the oil return chamber 4, and the second pipe section 512 connects to the input end of the blower 5. Inside the sealed cabinet 91, between the first pipe section 511 and the second pipe section 512, is a removable and replaceable filter element 92. This filter element 92 is an oil separator filter element, allowing oil to adhere to it while gas passes through. It filters the sucked-in oil, achieving gas-liquid separation, preventing oil from entering the blower 5 and causing damage, and simultaneously enabling oil recycling. The oil separator filter element 92 is prior art and will not be described in detail in this application. The sealed cabinet 91 consists of a cabinet body 911 and a sealing plate 912. The cabinet body 911 has an opening on one side, and the sealing plate 912 is fastened to the cabinet body 911 with bolts to close the opening. On each of the two opposite side walls inside the cabinet body 911, there are two spaced-apart plates 913. A slot is formed between each pair of plates 913. The two sides of the filter element 92 are inserted into these two slots to fix it. The sealing plate 912 is removed by loosening the bolts, and the filter element 92 can be pulled out to replace it.
