Description

Technical Field

[0001] The utility model relates to the technical field of cable production equipment, and more specifically, to a quick-heating grease tank of a cable grease machine. Background Art

[0002] During the production of cables, it is necessary to coat a layer of grease on the surface of the core wire to reduce the erosion of external water vapor on the internal conductor and improve the service life of the cable. Since the grease is in a solidified state at room temperature and the coating effect is poor, the grease machine basically heats the grease into a liquid state before coating.

[0003] In the prior art, the heating of the grease mainly uses methods such as electric heating tubes and resistance wires to directly heat the grease in the grease tank. The defects are as follows: the grease near the electric heating tube and the resistance wire melts quickly, and then the melted grease needs to be used to heat the unmelted grease, so the overall melting speed is slow. In addition, there is also a risk of electric leakage. Other heating methods, such as setting up an independently heated grease barrel and then transporting the grease through a circulating pump, have the following defects: the grease in the grease barrel melts quickly, but the solidified grease remaining in the pumping pipeline takes a long time to melt. The above problems need to be solved urgently. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the above background art and provide a quick-heating grease tank of a cable grease machine.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A quick-heating grease tank of a cable grease machine includes a grease tank body and a heating device. The heating device is arranged at the bottom of the grease tank body and includes a high-frequency induction coil and its controller. The high-frequency induction coil is not in direct contact with the grease tank body, and the bottom plate of the grease tank body is heated by electromagnetic induction.

[0007] On the top surface of the bottom plate of the grease tank body, there are a number of heat transfer fins. These heat transfer fins are all located in the inner cavity of the grease tank body and avoid the areas where the core wire passes through and the installation area of the coating component of the grease machine.

[0008] In a further embodiment, the heating device further includes a housing. The high-frequency induction coil is fixed in the inner cavity of the housing. The top surface of the housing is a microcrystalline plate, and the microcrystalline plate is located between the high-frequency induction coil and the bottom plate of the grease tank body.

[0009] In a further embodiment, the bottom of the housing is provided with air inlet holes, and the side surface of the housing is provided with heat dissipation holes. A heat dissipation fan is installed at the air inlet holes, and the heat dissipation fan is arranged facing the high-frequency induction coil.

[0010] In a further embodiment, a retaining ring extending outward is provided on the side walls around the ointment pool body.

[0011] In a further embodiment, the thickness of the bottom plate of the ointment pool body is greater than the thickness of the surrounding side walls.

[0012] The beneficial effects of the present utility model are as follows:

[0013] The present utility model uses a high-frequency induction coil to heat the bottom plate of the ointment pool body by electromagnetic induction, without direct contact with the ointment pool body, which can reduce the risk of electric leakage.

[0014] After the bottom plate of the ointment pool body is heated, the heat can be transferred to the surrounding side walls and also to the inner cavity of the ointment pool body through heat transfer fins, realizing heating the ointment from multiple positions and quickly melting it.

[0015] Since the temperature of the bottom plate of the ointment pool body is relatively high, the microcrystalline plate can isolate a part of the infrared radiation to the high-frequency induction coil and reduce the influence on the high-frequency induction coil.

[0016] The additional aspects and advantages of the present utility model will be partially given in the following description, partially become obvious from the following description, or be understood through the practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0023] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0024] As Figure 1 shown, this embodiment provides a rapid heating grease tank for a cable grease machine, including a grease tank body 1 and a heating device. The grease tank body 1 is open upward and is made of a metal material such as iron or steel that can generate electromagnetic induction. The heating device is arranged at the bottom of the grease tank body 1 and includes a housing 5, a high-frequency induction coil 4 fixedly installed in the inner cavity of the housing 5, and a controller 11 fixed on the housing 5. The controller 11 is used to control the power and duration of the high-frequency induction coil 4. The high-frequency induction coil 4 is laid flat under the bottom plate of the grease tank body 1 and is not in direct contact with the grease tank body 1, and is separated by a glass-ceramic plate 3 at the top of the housing 5. The bottom plate of the grease tank body 1 is heated by the high-frequency electromagnetic induction generated by the high-frequency induction coil 4. The glass-ceramic plate 3 and the controller 11 are both existing mature components and can be commercially obtained.

[0025] In order to accelerate the melting of the grease in the middle of the inner cavity of the grease tank, a plurality of heat transfer fins 2 that protrude upward are fixed on the top surface of the bottom plate of the grease tank body 1. A certain distance is maintained between the heat transfer fins 2. As Figure 2 shown, these heat transfer fins 2 are all located in the inner cavity of the grease tank body 1 and avoid the area where the core wire passes and the installation area 10 of the coating assembly of the grease machine. The coating assembly can adopt the form of a guide roller to press the core wire into the liquid grease. This is an existing structure and will not be introduced in detail here.

[0026] The thickness of the bottom plate of the ointment pool body 1 is greater than that of the surrounding side walls. After the bottom plate is heated by the high-frequency induction coil 4, the heat is transferred to the side walls and the heat transfer fins around the ointment pool, heating the ointment from the surroundings and inside.

[0027] In order to cool down the high-frequency induction coil 4, an air inlet hole 7 is provided at the bottom of the housing 5, and a heat dissipation hole 6 is provided on the side of the housing 5. A heat dissipation fan 8 is installed at the air inlet hole 7. The heat dissipation fan 8 is arranged facing the high-frequency induction coil 4. After being started, it blows cold air to cool down the high-frequency induction coil 4, and the hot air is then blown out through the heat dissipation port. The heat dissipation fan 8 is controlled by the controller 11.

[0028] Since the core wire may carry out some ointment when advancing, resulting in its adhesion to the outer wall of the ointment pool body 1, in order to prevent the ointment from affecting the air outlet of the heat dissipation hole 6, in this embodiment, the side walls around the ointment pool body 1 are provided with outwardly extending retaining rings 9, so as to prevent the ointment from flowing to the bottom of the ointment pool body 1.

[0029] During the operation of this embodiment, the controller 11 controls the high-frequency induction coil 4 to work. The bottom plate of the ointment pool is quickly heated, and the heat is gradually transferred to the side walls and the heat transfer fins around the ointment pool. Since the contact area with the ointment is increased, that is, the heating area is increased, the melting speed of the ointment can be improved. After the ointment melts, the controller 11 can keep the ointment in a liquid state by controlling the power of the high-frequency induction coil 4, which is convenient for the coating assembly to coat the core wire.

[0030] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
