Specific embodiments

[0027] In order to better understand the technical content of the present utility model, specific embodiments are hereby given and described in conjunction with the accompanying drawings as follows.

[0028] Combined with Figures 1-4 As shown, the present utility model provides a steel cord surface oiling device, which includes a collecting tray 1, an overflow tray 2 and an oil-absorbing felt 3.

[0029] The collecting tray 1 is arranged as a rectangular shell with openings at the top and both sides. The steel cord is introduced and led out through the openings on both sides of the collecting tray 1. The overflow tray 2 is arranged inside the collecting tray 1 and can store oil. The first end of the oil-absorbing felt 3 is arranged inside the overflow tray 2, and the second end of the oil-absorbing felt 3 extends to the surface of the steel cord, forming an oil delivery channel between the overflow tray 2 and the steel cord.

[0030] During the transportation of the steel cord, it rubs against the oil-absorbing felt 3, and a layer of oil is coated on the surface. However, this method cannot control the amount of oil applied and cannot meet the diverse production requirements.

[0031] Combined with Figure 1 As shown, a drip tube 4 is arranged above the collecting tray 1. The first end of the drip tube 4 extends into the collecting tray 1 and is directly above the second end of the oil-absorbing felt 3. Through the drip tube 4, oil can be delivered to the second end of the oil-absorbing felt 3, and a flow control valve 41 is arranged on the drip tube 4. By using the flow control valve 41 to control the dripping speed of the drip tube 4, when the transportation speed of the steel cord remains unchanged, the faster the dripping speed, the more the amount of oil applied, and the slower the dripping speed, the less the amount of oil applied, achieving the effect of accurately controlling the amount of oil applied.

[0032] Furthermore, the second end of the drip tube 4 is connected with a second oil storage bottle 42, and the second oil storage bottle 42 is fixed at a high position on the rack, so that the second oil storage bottle 42 can supply oil by gravity.

[0033] The excess oil can flow along the oil-absorbing felt 3 into the overflow tray 2, filling the overflow tray 2 with oil. When the flow control valve 41 is adjusted to the slowest dripping speed and still cannot meet the oil coating amount, the oil-absorbing felt 3 is used to absorb the oil in the overflow tray 2 for coating the steel cord.

[0034] Combined with Figure 3 and Figure 4 As shown, an oil-absorbing block 31 is provided at the second end of the oil-absorbing felt 3. An oil coating gap 301 for the steel cord to pass through is formed on the oil-absorbing block 31. The steel cord passes through the oil coating gap 301, which can wrap the steel cord and make the oil coating more uniform.

[0035] Furthermore, a V-shaped guiding port 302 for guiding the steel cord into the oil coating gap 301 is provided at the top of the oil coating gap 301. When adjusting the position of the oil-absorbing felt 3, the steel cord is introduced into the oil coating gap 301 along the guiding port 302, which is convenient for operation by personnel.

[0036] Combined with Figure 4 As shown, the inner side surface of the oil coating gap 301 is successively provided with a first oil coating area 311, a second oil coating area 312, and a third oil coating area 313 with gradually decreasing oil coating amounts from top to bottom. By adjusting the position of the oil-absorbing felt 3, the steel cord can pass through different oil coating areas, and when the steel cord passes through different oil coating areas, the oil coating amounts on the surface are different, increasing the oil coating amount control methods and improving the use flexibility.

[0037] In a specific embodiment, the first oil coating area 311, the second oil coating area 312, and the third oil coating area 313 are respectively composed of a plurality of hemispherical grooves arranged in an array. Under the same distribution density, the diameters of the hemispherical grooves in the first oil coating area 311, the second oil coating area 312, and the third oil coating area 313 gradually decrease. The oil storage amounts inside the hemispherical grooves with different diameters are different, so that when the steel cord passes through different oil coating areas, the oil coating amounts on the surface are also different.

[0038] In a preferred embodiment, the oil-absorbing block 31 is a sponge with a relatively high density. While meeting the oil absorption performance, hemispherical grooves can be formed on its side surface.

[0039] Combined with Figure 2 As shown, a bracket 5 for supporting the second end of the oil-absorbing felt 3 is provided on the overflow tray 2. A fixing member 6 for fixing the second end of the oil-absorbing felt 3 on the bracket 5 is connected to the bracket 5 to maintain the contact between the oil-absorbing felt 3 and the steel cord.

[0040] In a specific embodiment, the fixing member 6 is set as a magnet, and the bracket 5 is correspondingly set as a ferromagnetic material. Using the magnetic attraction of the magnet, the oil-absorbing felt 3 is clamped on the bracket 5, and the disassembly and assembly of the magnet are relatively convenient, which is beneficial to the position adjustment of the oil-absorbing felt 3.

[0041] Combined with Figure 1As shown in the figure, a first oil storage bottle 11 for collecting oil fluid is connected to the bottom of the collection tray 1. When the oil fluid in the overflow tray 2 is full, it overflows into the collection tray 1 and is collected by the first oil storage bottle 11.

[0042] In a preferred embodiment, the bottom of the collection tray 1 is arranged in a funnel-shaped structure, which can better concentrate and drain the oil fluid to the first oil storage bottle 11 for collection.

[0043] In a specific embodiment, the open ends of the first oil storage bottle 11 and the second oil storage bottle 42 are both provided with external thread ports of the same specification, and the bottom of the collection tray 1 and the second end of the drip oil pipe 4 are provided with internal thread ports of the same specification, so that the first oil storage bottle 11 and the second oil storage bottle 42 can be used interchangeably.

[0044] Combined with the above embodiments, by arranging a drip oil pipe 4 above the oil absorption felt 3 in contact with the steel cord, and a flow control valve 41 is provided on the drip oil pipe 4. The drip oil pipe 4 can convey oil fluid to the second end of the oil absorption felt 3, and a flow control valve 41 is provided on the drip oil pipe 4. The flow control valve 41 is used to control the dripping speed of the drip oil pipe 4. When the conveying speed of the steel cord remains unchanged, the faster the dripping speed, the more the amount of oil applied; the slower the dripping speed, the less the amount of oil applied, achieving the effect of accurately controlling the amount of oil applied.

[0045] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Those with ordinary knowledge in the technical field to which the present utility model belongs can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to what is defined by the claims.
