Description

Technical Field

[0001] The present invention relates to the technical field of cables, in particular to the technical field of cable oil passing devices. Background Art

[0002] Cable is a medium for transmitting electric energy or signals. It is usually in the shape of a rope made of several or several groups of cores twisted together. It has the characteristics of internal power supply and external insulation. During the use of cables, there are quantitative requirements for the sheath stripping rate (if the sheath layer and the center core wire are too tightly bonded, the sheath layer is not easy to strip off; if the sheath layer and the center core wire are too loosely bonded, the cable core structure is unstable. There are generally two ways to solve this problem. One is to pass the center core wire through a powder box to apply a layer of talcum powder on the surface (i.e., powdering process), and the other is to apply a layer of oil on the surface of the center core wire (i.e., oiling process).

[0003] The traditional manual pulling oiling method not only has the problem of low oiling efficiency, but also easily leads to uneven oiling. The existing oiling equipment mainly uses a rotating conveyor belt to circulate the oilcloth into the oil first, and then wipes the surface of the center core wire, such as a center core wire oiling device for wire and cable production with announcement number CN112435803B. However, the equipment cannot oil the center core wire in the entire circumference, and the liquid tank is also prone to gradually accumulate impurities after working for a period of time to affect the subsequent oiling effect. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the prior art and to provide a continuous cable oiling device which can ensure that the central core wire can be oiled stably and evenly in the entire circumference.

[0005] To achieve the above-mentioned purpose, the present invention proposes a continuous cable oil-passing device, including an oil-passing mechanism, an oil tank, a filter, an oil pump, a puller and a central controller. The oil-passing mechanism is composed of two detachable arc plates. The two arc plates are respectively spliced ​​together to form a threading channel for the center core wire to pass through and a spiral oil filling groove arranged around the threading channel. The spiral oil filling grooves are respectively connected to the oil inlet and oil outlet of the plate body equipped with a plate body joint through the oil filling hole of the plate body. A circulating oil circuit is formed between the oil-passing mechanism, the oil tank and the filter through the oil pump and the oil pipe. The oil-passing mechanism allows the center core wire to pass through the threading channel section by section through the puller. The central controller is electrically connected to the filter, the oil pump and the puller, respectively.

[0006] Preferably, the two halves of the arc plate are snap-jointed with each other and the joint surface is sealed by a plate sealing ring.

[0007] Preferably, the spiral oil injection groove is also filled with oil felt rope.

[0008] Preferably, the puller includes a static guide wheel, a dynamic guide wheel, a driving member and a support frame. The static guide wheel and the dynamic guide wheel are arranged opposite to each other and form a narrow gap for the central core wire to pass through. The dynamic guide wheel is driven by the driving member to move closer to or away from the static guide wheel to adjust the size of the gap. The static guide wheel and the driving member are respectively supported by the support frame.

[0009] Preferably, the filter comprises a base shaft, a filter membrane, a sleeve and a sealing end seat, the filter membrane is wrapped around the outside of the base shaft in circles and forms a membrane roll together with the base shaft, the membrane roll is placed in the sleeve along the cylinder channel and the longitudinal ends are respectively encapsulated by sealing end seats, and the cylinder wall of the sleeve is respectively provided with a cylinder oil inlet and a cylinder oil outlet with a cylinder joint, and the cylinder oil inlet and the cylinder oil outlet are respectively connected to the cylinder channel through the cylinder oil filling hole.

[0010] Preferably, the sealing end seat comprises an end seat and a positioning sleeve, the end seat having a socket for inserting a membrane roll, the sleeve supporting the end seat at the periphery of the socket, the sleeve and the end seat being sealed at the supporting surface by a seat body sealing ring, and the end seat being indirectly connected to the sleeve via the positioning sleeve.

[0011] Preferably, the socket is in a step shape and an annular groove is provided on the step surface. A gasket is installed in the socket, and the outer edge of the gasket extends into the annular groove.

[0012] Preferably, the sleeve and the end seat are respectively provided with outer threads of the sleeve and outer threads of the seat, and the sleeve and the end seat are connected together by being threadedly sleeved by the same sleeve.

[0013] Beneficial effects of the present invention: 1) The oil-passing mechanism is formed by using two arc plates that can be assembled to form a threading channel and a spiral oil injection groove, and the oil-passing mechanism is used in conjunction with an oil tank, a filter, an oil pump and a puller. Thus, while the puller drives the center core wire to pass through the oil-passing mechanism section by section along the threading channel, the oil tank, the filter and the oil pump are used to make the filtered oil circulate around the center core wire along the spiral oil injection groove, ultimately ensuring that the center core wire can be stably and evenly oiled in all directions; 2) By filling the spiral oiling groove with oil felt rope, the center core wire can be wiped section by section all around the center core wire instead of being directly immersed in oil section by section all around the center core wire, so that the oil film on the center core wire surface is more uniform and thin, and oil leakage can be avoided to a certain extent; 3) By wrapping the filter membrane around the base shaft in circles and forming a membrane roll together with the base shaft, the membrane roll is placed inside the sleeve along the cylinder channel and the longitudinal ends are respectively sealed by sealing end seats composed of end seats and positioning sleeves. Not only can the filter membranes arranged in layers be used to effectively filter the oil in a small space, but the membrane roll can also be easily disassembled and replaced; 4) By installing a seat body sealing ring at the adjacent surface of the end seat and the sleeve, and adding a gasket in the socket of the end seat for the membrane roll to be inserted, when the end seat and the sleeve are threadedly connected together by the same sleeve, the axial ends of the filter element composed of the membrane roll and the sleeve can be quickly sealed.
