[0002] In the leather processing industry, oiling is a crucial finishing process. By uniformly applying fatliquoring agents, waterproofing oils, and other treatment agents to the leather surface, the softness, fullness, feel, and physical properties of the leather can be significantly improved. Therefore, oiling equipment is one of the essential devices in leather processing.

[0003] Existing oil rolling devices have a complex structure and an unreasonable design. During the high-speed continuous coating process, a large amount of excess oil will drip from the edge of the leather or be squeezed and splashed between the rollers. Therefore, an oil drain pipe is designed to collect the oil. However, the filter plate for filtering impurities is located at the top of the oil drain pipe, which greatly increases the difficulty of cleaning the filter plate. To address this problem, the inventors designed an oil rolling device for leather processing. Utility Model Content

[0019] Please see Figures 1 to 4 The present invention provides an embodiment of a leather processing oil rolling device, which includes a frame 1, an inclined frame 2, an oil drain pipe 9, and a filter element 10. The inclined frame 2 is disposed inside the frame 1 and has a hollow cavity structure. The oil drain pipe 9 is inserted into the interior of one side of the inclined frame 2, and the filter element 10 is disposed at the bottom of the oil drain pipe 9. The filter element 10 includes a filter box 101, a filter plate 102, a limiting plate 103, and a guide plate 104. The filter box 101 is fixed to the outer wall at the bottom of the oil drain pipe 9. The filter plate 102 is snapped into the bottom of the filter box 101. The cross-sectional view of the filter plate 102 is convex. The limiting plate 103 is snapped into the inside of the filter box 101, and the surface of the limiting plate 103 abuts against the surface of the filter plate 102. The guide plate 104 is fixed to the surface of the limiting plate 103.

[0020] The frame 1 is the basic support structure of the entire equipment. The inclined frame 2 provides an inclined plane to support and guide the leather into the coating area. The oil drain pipe 9 is the channel for oil recovery, which guides the excess oil collected in the inclined frame 2 into the filter element 10 below. The filter box 101 is a container for the filtration process, receiving waste oil from the oil drain pipe 9. The core function of the filter plate 102 is to intercept and adsorb the leather fibers, dust and impurities contained in the recovered oil, preventing these impurities from re-entering the coating system and affecting the coating quality or damaging the equipment. The "U"-shaped cross-section design allows the filter plate 102 to be firmly locked in the filter box 101. The main function of the limiting plate 103 is to press the filter plate 102 from above to prevent it from shifting or loosening under the impact of oil. The guide plate 104 facilitates the fixed installation of the limiting plate 103 in the required position.

[0021] A notch 105 is provided on one side of the guide plate 104, and a guide post 106 is fixed on the outer wall of the filter box 101 near the notch 105. The guide post 106 is located inside the notch 105.

[0022] The notch 105 facilitates the quick and easy positioning of the guide plate 104 on the outside of the guide post 106, which in turn restricts the guide plate 104 to the desired position.

[0023] The guide post 106 has an internal threaded connection to a threaded post 107, one side of which is inserted into the inside of the guide plate 104.

[0024] The threaded post 107 is used to connect the guide post 106 to the guide plate 104, thereby fixing the guide plate 104 in the desired position.

[0025] A guide block 108 is fixed to the surface of the threaded column 107. The surface of the guide block 108 is in contact with the surface of the guide plate 104. A connecting pipe 11 is connected through the bottom of the filter box 101.

[0026] The guide block 108 is an operating handle, which makes it easy to rotate the threaded post 107 to the desired position. The connecting pipe 11 is used to discharge the filtered clean oil.

[0027] The frame 1 is equipped with a conveyor roller 3 and a coating roller 4. The conveyor roller 3 and the coating roller 4 are on the same vertical horizontal line, and the coating roller 4 is located inside the inclined frame 2.

[0028] The conveyor roller 3 is the active roller, responsible for pulling the leather so that it passes through the coating area smoothly and continuously. The coating roller 4 is a roller that comes into direct contact with the leather. Its surface carries a certain amount of oil and evenly coats the leather surface with oil as it passes through.

[0029] The frame 1 is equipped with a metering roller 5 and an oil leveling roller 6. The metering roller 5 is located between the coating roller 4 and the oil leveling roller 6.

[0030] Metering roller 5 and coating roller 4 are closely fitted to form a precise gap. Its function is to accurately control the thickness of the oil film transferred to coating roller 4. It is a key component to ensure coating uniformity and accurate dosage. Oil leveling roller 6 is partially immersed in oil. By rotating, it lifts the oil in oil tank 7 and initially evens it, and then transfers it to metering roller 5 to ensure that the supplied oil is foam-free and uniform.

[0031] The frame 1 is equipped with an oil storage tank 7. The bottom of the oil distribution roller 6 is located inside the oil storage tank 7. The oil storage tank 7 is fixed with a conveying pipe 8 on the side away from the oil discharge pipe 9.

[0032] The oil storage tank 7 is used to store and supply the oily treatment agent required for coating. The delivery pipe 8 is connected to an external oil supply system to continuously replenish the oil storage tank 7 with new oil and maintain a stable liquid level.

[0033] Working principle: When oiling is required, the leather is placed on the inclined frame 2. Under the design of the transmission mechanism, the drive roller 3 is rotated, so that the leather moves on the inclined frame 2. When the leather passes between the coating roller 4 and the metering roller 5, which precisely control the amount of oil, the oiling operation of the leather is completed. At the same time, under the action of the conveying pipe 8, oil is continuously conveyed into the oil storage tank 7, so that the oil coating roller 6 is coated with oil. Then, through the metering roller 5, the oil is continuously conveyed to the coating roller 4. Excess oil is conveyed to the filter box 101 through the oil drain pipe 9. Under the action of the filter plate 102, impurities are left inside the filter box 101. Finally, the filtered oil is discharged through the connecting pipe 11. When the filter plate 102 needs to be replaced, a rotational force is applied to the guide block 108, causing the threaded post 107 to disengage from the guide plate 104. Then, a pulling force is applied to the guide plate 104, causing the limiting plate 103 to be pulled out from the filter box 101. The filter plate 102 is then removed from the filter box 101, and the new filter plate 102 is placed inside the filter box 101. The limiting plate 103 is then inserted into the filter box 101. During this process, the guide plate 104 can be precisely positioned and installed to the required position by the notch 105. Finally, a rotational force is applied to the guide block 108, causing the threaded post 107 to be inserted into the guide plate 104, and the guide block 108 to fit against the surface of the guide plate 104.

[0034] It should be noted that the transmission mechanism is existing technology, so it will not be discussed in detail here.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
