[0030] 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.

[0031] See also Figure 1-8 The utility model provides a technical solution: an oil-coated steel rolling mill, comprising a roller body 1, conveyor belts 2 are installed at the inlet and outlet of the roller body 1, and an oiling mechanism is installed on the conveyor belt 2 at the feed end, and the oiling mechanism is used to apply grease to the steel plate entering the roller body 1.

[0032] Specifically, the oiling mechanism includes a bracket 3 installed on the conveyor belt 2, a cylinder 4 is installed on the upper end of the bracket 3, the piston end of the cylinder 4 is connected to the connecting sleeve 5, a double-layer mounting plate 6 is installed in the connecting sleeve 5, and an oiling roller brush 10 is rotatably provided at the lower end of the double-layer mounting plate 6. After the cylinder 4 pushes the double-layer mounting plate 6 downward, the oiling roller brush 10 is fitted with the upper surface of the steel plate to apply grease to the steel plate.

[0033] In order to store grease on the oiling roller brush 10, a delivery pipe 7 is installed at the upper end of the double-layer mounting plate 6. The oil inlet end of the delivery pipe 7 is connected to the oil tank 8 through an oil pipe. A delivery pump 9 is installed on the oil pipe. The delivery pump 9 is used to deliver the grease in the oil tank 8 to the delivery pipe 7. A distance is left between the oil outlet of the delivery pipe 7 and the oiling roller brush 10, so that the grease can be delivered from the delivery pipe 7 to the oiling roller brush 10, making it convenient to oil the steel plate.

[0034] Furthermore, an oil balancing mechanism is installed on one side of the oiling mechanism, and the oil balancing mechanism includes a pair of limit rails 11, the limit rails 11 are connected to the bracket 3, a top plate 13 is slidingly arranged in the limit rails 11, a slide plate 14 is symmetrically arranged on the lower side of the top plate 13, a hollow sleeve 15 is slidingly arranged on the outer side of the slide plate 14, and an oil balancing roller brush 16 is rotatably arranged between the two hollow sleeves 15. According to the thickness of the steel plate, the top plate 13 is slid downward in the limit rails 11 so that the oil balancing roller brush 16 contacts the upper surface of the steel plate, and the grease on the steel plate is evenly spread twice to ensure the uniformity of the grease.

[0035] A screw rod 12 is rotatably provided in each of the two limit rails 11. The two screw rods 12 are respectively threadedly connected to the two ends of the top plate 13. The two screw rods 12 are driven by a motor. When the two screw rods 12 rotate, the top plate 13 can be automatically slid, thereby improving the stability of the oil-distributing roller brush 16.

[0036] A steel plate limiting mechanism is installed on the lower side of the oil balancing mechanism. When the oil balancing mechanism descends, the two ends of the steel plate limiting mechanism are forced to move closer to each other and limit according to the width of the steel plate.

[0037] Among them, the limiting mechanism includes a screw rod 21 rotatably arranged on the two side frames of the conveyor belt 2, one end of the screw rod 21 is connected to a bevel gear 20, and the lower ends of the two screw rods 12 are connected to a bevel gear 19, which meshes with the bevel gear 20, and a telescopic sleeve 22 is threadedly connected to the screw rod 21, and a telescopic rod 23 is slidably arranged in the telescopic sleeve 22, and a positioning plate 24 is fixedly arranged at one end of the telescopic rod 23. Therefore, when the screw rod 12 rotates, the screw rod 21 is prompted to rotate together. According to the meshing state of the two sets of bevel gears 19 and bevel gears 20, the thread directions of the two screw rods 21 can be set in reverse, so that the two telescopic sleeves 22 are close to or away from each other when the screw rod 21 rotates, thereby prompting the two positioning plates 24 to be located on both sides of the steel plate to limit it, thereby improving the stability of the steel plate.

[0038] Grooves 26 are provided on both side frames of the conveyor belt 2 , and the bottom of the telescopic sleeve 22 is slidably connected to the grooves 26 to limit the moving direction of the telescopic sleeve 22 .

[0039] It is worth noting that the positioning plate 24 is connected to the bottom of the telescopic rod 23 through spring 25, and a spring 18 is provided in the hollow sleeve 15. The upper end of spring 18 is connected to the lower end of the slide plate 14. Through the elastic action of spring 18 and spring 25, the descending stroke of the oil-equalizing roller brush 16 is adapted to the moving stroke of the positioning plate 24. When the width or thickness of the steel plate is different, the oil-equalizing roller brush 16 and the positioning plate 24 can realize their functions by squeezing or releasing spring 18 and spring 25.

[0040] In addition, sliding grooves 17 are provided on both sides of the hollow sleeve 15 , and the protrusions on both sides of the slide plate 14 are slidably connected to the sliding grooves 17 , thereby improving the stability of the slide plate 14 .

[0041] In summary, the working principle of an oil-coated steel rolling mill of an embodiment of the present invention is as follows: before the steel plate enters the rolling mill body 1, the oiling mechanism oils the steel plate, and at the same time, the motor drives the screw 12 to make the top plate 13 with the oil-equalizing roller brush 16 descend and contact the upper surface of the steel plate, so as to apply the grease on the steel plate for the second time, and while the screw 12 rotates, the bevel gear 19 and the bevel gear 2 20 are engaged, so that the two telescopic sleeves 22 bring the two positioning plates 24 closer to each other to limit the steel plate according to the width of the steel plate, and the elasticity of the spring 18 and the spring 2 25 is used to make the descending stroke of the oil-equalizing roller brush 16 match the moving limit stroke of the positioning plate 24, so as to meet the situation where the oil-equalizing roller brush 16 and the positioning plate 24 move at the same time.

[0042] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
