Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to an oiling device for cold-rolled strip steel. Background Technology

[0002] The oiling device for cold-rolled strip steel is a device used to uniformly coat the surface of cold-rolled strip steel with anti-rust oil, aiming to improve the quality and efficiency of oiling while reducing manual operation and missed coating.

[0003] When applying oil to protect cold-rolled steel strips, the traditional method is to directly apply the oil to the surface of the steel strip and then recover the excess protective oil. However, during spraying, the oil can only be applied to the upper surface of the steel strip, and it is not possible to automatically spray the oil using the driving force of the conveyor. To solve the above problems, an oiling device for cold-rolled steel strips is needed. Utility Model Content

[0007] Preferably, the pouring mechanism includes a connecting plate fixedly connected to the surface of the oil storage tank, a rotating disk rotatably connected to the inner wall of the connecting plate, a first bevel gear fixedly connected to the output end surface of the motor, a second bevel gear fixedly connected to one end of the rotating disk, the first bevel gear meshing with the second bevel gear, a first gear fixedly connected to the surface of the upper friction roller, and a second gear fixedly connected to the surface of the lower friction roller, the first gear meshing with the second gear.

[0008] Furthermore, an oil tank is fixedly connected to the inner bottom wall of the oil storage tank, and a sliding rod is slidably connected to the inner wall of the oil tank. One end of the sliding rod penetrates the outer surface of the oil storage tank, and a U-shaped rack is fixedly connected to the upper surface of the sliding rod.

[0009] Preferably, a spiral plate is rotatably connected to the surface of the connecting plate, a sector toothed plate is fixedly connected to the lower surface of the spiral plate, the sector toothed plate meshes with a U-shaped rack, a convex shaft is fixedly connected to the surface of the rotating disk, the convex shaft is eccentrically installed with the center of the rotating disk, and the convex shaft is installed inside the spiral plate.

[0010] Furthermore, a piston plate is fixedly connected to one end of the sliding rod, the outer surface of the piston plate is adapted to the inner wall of the oil tank, and an oil replenishment pipe is fixedly connected to the inner wall of the oil tank.

When the piston plate slides away from the oil replenishment pipe, the oil replenishment pipe pumps the liquid in the oil storage tank into the oil tank. When the piston plate moves towards the oil replenishment pipe, the piston plate pushes the liquid in the oil tank into the oil supply pipe and then into the oil spraying pipe to spray out the oil onto the upper surface of the steel strip. Part of the surface of multiple oil-adhesive rollers is immersed in the oil in the oil storage tank. After contacting the moving steel strip surface, they rotate and coat the oil on their surface onto the lower surface of the steel strip. The advantage of this is that the oiling operation on the upper and lower surfaces of the steel strip is automatically performed by conveying driving force. Attached Figure Description

[0023] By setting motor 6, the upper friction roller 4 is driven to rotate, and by setting first bevel gear 12, the second bevel gear 11 is driven to rotate.

[0024] In this utility model, reference Figure 3 and Figure 4 An oil tank 20 is fixedly connected to the inner bottom wall of the oil storage tank 1. A sliding rod 19 is slidably connected to the inner wall of the oil tank 20. One end of the sliding rod 19 passes through the outer surface of the oil storage tank 1. A U-shaped rack 17 is fixedly connected to the upper surface of the sliding rod 19.

[0025] By setting the sliding rod 19, the connected piston plate 25 is driven to reciprocate. By setting the U-shaped rack 17, the sliding rod 19 is driven to move.

[0026] In this utility model, reference Figure 3 A spiral plate 15 is rotatably connected to the surface of the connecting plate 9. A fan-shaped toothed plate 18 is fixedly connected to the lower surface of the spiral plate 15. The fan-shaped toothed plate 18 meshes with the U-shaped rack 17. A convex shaft 16 is fixedly connected to the surface of the rotating disk 10. The convex shaft 16 is eccentrically installed with the center of the rotating disk 10. The convex shaft 16 is installed inside the spiral plate 15.

[0027] By setting the convex shaft 16, the spiral plate 15 and the sector toothed plate 18 are driven to swing back and forth as a whole. By setting the sector toothed plate 18, the U-shaped rack 17 is driven to move back and forth.

[0029] By setting the piston plate 25, when the piston plate 25 moves toward the oil replenishment pipe 23, it squeezes the oil in the oil tank 20 to the oil supply pipe 21. When the piston plate 25 moves away from the oil replenishment pipe 23, it pumps the oil in the oil storage tank 1 to the oil tank 20 through the oil replenishment pipe 23.

[0030] In this utility model, reference Figure 3 and Figure 4 The inner wall of the oil tank 20 is fixedly connected to the oil supply pipe 21, the top end of the oil supply pipe 21 is fixedly connected to the inner wall of the oil spray pipe 3, the surface of the oil replenishment pipe 23 is fixedly connected to the first one-way valve 24, and the surface of the oil supply pipe 21 is fixedly connected to the second one-way valve 22.

The upper friction roller 4 drives the first gear 13 to rotate, and the first gear 13 drives the second gear 14 and the lower friction roller 5 to rotate as a whole, so that the upper friction roller 4 and the lower friction roller 5 rotate in opposite directions, thus conveying the cold-rolled steel strip. The output of the motor 6 drives the first bevel gear 12 to rotate, and the first bevel gear 12 drives the second bevel gear 11 to rotate. The second bevel gear 11 drives the rotating disk 10 to rotate, and the rotating disk 10 drives the eccentrically mounted cam shaft 16 to rotate, which in turn drives the oscillating plate 15 and the fan-shaped toothed plate 18 to swing. The movement of the fan-shaped toothed plate 18 drives the U-shaped toothed plate to swing. The U-shaped rack 17 reciprocates, and the sliding rod 19 moves. The sliding rod 19 drives the piston plate 25 to slide back and forth. When the piston plate 25 slides away from the oil replenishment pipe 23, the oil replenishment pipe 23 pumps the liquid in the oil storage tank 1 into the oil tank 20. When the piston plate 25 moves closer to the oil replenishment pipe 23, the piston plate 25 pushes the liquid in the oil tank 20 into the oil supply pipe 21. The oil supply pipe 21 sends the oil to the oil spraying pipe 3 to spray out, and performs oiling operation on the upper surface of the steel strip. Part of the surface of multiple oil-sticking rollers 2 is immersed in the oil in the oil storage tank 1. After contacting the moving steel strip surface, they rotate and coat the oil on their surface onto the lower surface of the steel strip.
