[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See Figures 1-4 As shown, it includes an oil purification frame 1, a bracket plate 2 is provided on one side of the oil purification frame 1, a support frame 3 is provided above the bracket plate 2, and a jet impurity removal structure is provided on the top of the support frame 3. An oiling frame 11 is provided in the middle above the oil purification frame 1, and arrays of opposite wire assemblies are respectively provided in the oiling frame 11 and the support frame 3, and a balanced driving structure is provided on the support frame 3; a circulating filtering structure is provided in the oiling frame 11 and the oil purification frame 1; and an oil pressure structure is provided on the end of the oiling frame 11 away from the bracket plate 2.

[0025] See Figures 1-4 As shown, the wire assembly includes a wire shaft 7 rotatably mounted in the support frame 3, and a plurality of wire wheels 8 are provided on the wire shaft 7 at equal intervals. There are two sets of wire assemblies on the support frame 3, and the two wire shafts 7 have the same height.

[0026] The balanced drive structure includes a drive motor 9 arranged on one side of the support frame 3, the rotating shaft of the drive motor 9 is connected to one of the wire rotating shafts 7, and a sprocket wheel assembly 10 is provided on the other side of the support frame 3, and the sprocket wheel assembly 10 is transmission-connected between the two wire rotating shafts 7 on the support frame 3.

[0027] As an optimization solution of the present invention, the two sets of conductor assemblies are kept rotating at the same speed by driving the motor 9 and the sprocket assembly 10, thereby ensuring that the linear speed of the fibers transported between the two sets of conductor assemblies remains balanced.

[0028] See Figures 1-4As shown in the figure, the jet impurity removal structure includes an air duct 5 and a fan 4 provided at the top of the support frame 3. The air outlet of the fan 4 is connected to the inside of the air duct 5 through a pipe. The air duct 5 is directly above the two wire rotating shafts 7 on the support frame 3. Several jet nozzles 6 are provided at the lower end of the air duct 5, and the jet nozzles 6 are inclined towards the side away from the clean oil frame 1.

[0029] As an optimized solution of the present utility model, a fan 4 is provided to blow the impurities attached to the fiber line downward through the jet nozzles 6. Moreover, due to the inclined setting, the blown impurities will move towards the side away from the clean oil frame 1 and will not enter the oil; the balanced drive structure keeps the shape of the fiber line stable and will not cause slack or jitter due to the air flow.

[0030] See Figures 1-4 As shown in the figure, the circulating filtration structure includes a filter screen 12 provided at the center of the bottom of the upper oil frame 11. The bottom center of the upper oil frame 11 is concave, and a hole is opened at the center of the bottom of the upper oil frame 11. The filter screen 12 is provided in the hole. An oil transfer pump 20 is provided outside the clean oil frame 1. The inlet end of the oil transfer pump 20 is connected to the bottom of the clean oil frame 1 through an upper oil pipe 21, and the outlet end of the oil transfer pump 20 is connected to the upper oil frame 11 through an outlet oil pipe 22.

[0031] As an optimized solution of the present utility model, an oil transfer pump 20 is provided to make the oil flow in the order of "upper oil frame 11 - clean oil frame 1 - upper oil frame 11". During the flow of the oil, the impurities deposited at the bottom of the upper oil frame 11 are filtered through the filter screen 12, thereby ensuring the purity of the oil in the clean oil frame 1. At the same time, the flow of the oil will cause the impurities to continuously accumulate at the filter screen 12 and will not float and adhere to the fiber line.

[0032] See Figures 1-4 As shown in the figure, the oil pressing structure includes an oil pressing support 13 provided on the upper oil frame 11. An oil pressing roller shaft II 15 is rotatably installed in the oil pressing support 13. Chute grooves 18 are respectively opened on both sides of the oil pressing support 13 above the oil pressing roller shaft II 15. Slide blocks 17 are respectively slidably installed in the two chute grooves 18. A spring 19 is provided at the top of each slide block 17. An oil pressing roller shaft I 14 is provided between the two slide blocks 17. Both ends of the oil pressing roller shaft I 14 are respectively connected with a rotating shaft 16, and the rotating shaft 16 is connected to the slide block 17 through a bearing.

[0033] As an optimized solution of the present utility model, a spring 19 is provided to drive the slide block 17 to press downward along the chute groove 18, so that the oil pressing roller shaft I 14 is continuously pressed against the oil pressing roller shaft II 15, thereby squeezing out the excess oil on the fiber line after oiling.

[0034] See Figures 1-4As shown in the figure, a liquid level gauge 23 is provided inside the oil feeding frame 11. The liquid level gauge 23 is electrically connected to the oil transfer pump 20 and is also connected to an external status monitoring device.

[0035] As an optimized solution of the present utility model, a liquid level gauge 23 is provided to monitor the height of the oil liquid inside the oil feeding frame 11 in real time. When it is found that the height of the oil liquid exceeds the set value, it indicates that the filter screen 12 is blocked. Thereby, the oil transfer pump 20 is stopped and an abnormal signal is sent until the user cleans the filter screen 12.

[0036] The usage process of the present utility model:

[0037] First, the fiber wire is passed through the array wire assembly in sequence, and then through the first oil pressing roller shaft 14 and the second oil pressing roller shaft 15, and led to the subsequent processing equipment to start the oiling device.

[0038] The impurities on the fiber wire are removed by the air flow blown out from the air jet head 6 first, and then enter the oil feeding frame 11 and are immersed in the oil liquid for oiling. At the same time, the circulating filtration structure continues to operate, and the impurities remaining on the surface of the fiber wire and entering the oil liquid are concentrated at the filter screen 12. The fiber wire after oiling can be output after oil pressing.

[0039] When the oil transfer pump 20 stops operating and the monitoring device detects an abnormality, the operator needs to check the filter screen 12, suspend production, clean the filter screen 12, and then resume the operation of the equipment.

[0040] It should be understood that the above specific embodiments of the present utility model are only used for exemplary illustration or explanation of the principle of the present utility model, and do not constitute a limitation to the present utility model. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present utility model shall be included within the protection scope of the present utility model. In addition, the appended claims of the present utility model are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
