When one group of lubricating oil barrels 1 is injecting lubricating oil, another group of lubricating oil barrels 1 can replenish the lubricating oil, thereby avoiding the phenomenon of stopping the machine to replenish the lubricating oil, thereby improving the operating efficiency of the high-pressure roller mill.

[0028] Furthermore, an adjustment mechanism is provided on one side of the connecting plate 11, and the adjustment mechanism includes a mounting plate 3, the mounting plate 3 is arranged on one side of the connecting plate 11, a fixing block 31 is fixedly connected to the surface of the mounting plate 3, a second motor 32 is fixedly connected to the surface of the fixing block 31, a second reciprocating screw 33 is fixedly connected to the output shaft of the second motor 32, a square nut 34 is threadedly connected to the surface of the second reciprocating screw 33, and the square nut 34 is fixedly connected to the bottom of the connecting plate 11. The adjustment mechanism can change the position of the injection lubricating oil of the injection head 13, thereby improving the uniformity of the injection of the lubricating oil, and further improving the use effect of the lubricating oil.

[0029] Furthermore, two groups of lubricating oil barrels 1 are provided, and the two groups of lubricating oil barrels 1 are connected by a connecting plate 11 and a support rod 2, and a connecting pipe 12 is in a "human" shape. The lubricating oil inside the two groups of lubricating oil barrels 1 can be injected into the bearings and rollers of the high-pressure roller mill through the connecting pipe 12 and the injection head 13.

[0030] Furthermore, the first reciprocating screw 22 rotates between the support rod 2 and the connecting plate 11, and the first motor 21 drives the first reciprocating screw 22 to rotate through the output shaft. The first reciprocating screw 22 drives the adjusting nut 23 to slide and rise and fall on the surface of the lubricating oil barrel 1 through rotation. One side of the adjusting nut 23 is arc-shaped and is slidably connected to the surface of the lubricating oil barrel 1, so that the adjusting nut 23 can be stably lifted and lowered on the surface of the lubricating oil barrel 1.

[0031] Furthermore, two groups of first reciprocating screw rods 22 and adjusting nuts 23 are provided. The adjusting nuts 23 slide back and forth and rise and fall on the surface of the lubricating oil barrel 1. The adjusting nuts 23 drive the piston rod 26 to rise and fall through the movable rod 24 and the connecting rod 25.

The control switch 210 controls the switch of the solenoid valve 211. Two groups of connecting rods 25 are provided, and the two groups of connecting rods 25 correspond to the two groups of control switches 210 respectively. After the control switch 210 is pressed, the open solenoid valve 211 will be closed and the closed solenoid valve 211 will be opened.

The fixed block 31 drives the square nut 34 to slide on the surfaces of the connecting plate 11 and the mounting plate 3 through rotation. The position of the mounting plate 3 is relatively fixed, and the square nut 34 drives the connecting plate 11 to slide on the surface of the mounting plate 3 at this time.

[0035] Furthermore, the square nut 34 slides back and forth on the surfaces of the connecting plate 11 and the mounting plate 3.

When there is no lubricating oil inside the lubricating oil barrel 1, the connecting rod 25 will trigger the control switch 210 on the connecting pipe 12. At this time, the control switch 210 will close the open solenoid valve 211 and open the closed solenoid valve 211. At this time, the lubricating oil on another group of lubricating oil barrels 1 can be injected, and then the lubricating oil barrel 1 that has run out of lubricating oil can be replenished with lubricating oil through the replenishing pipe 28. There is no need to shut down the high-pressure roller mill, which improves the operating efficiency of the high-pressure roller mill.

[0037] The output shaft of the second motor 32 drives the second reciprocating screw 33 to rotate on the fixed block 31. The second reciprocating screw 33 drives the square nut 34 to slide on the surface of the mounting plate 3 through rotation. The square nut 34 drives the connecting plate 11 to slide on the surface of the mounting plate 3. The connecting plate 11 drives the connecting pipe 12 and the injection head 13 to slide through the lubricating oil barrel 1, thereby changing the position of the injection lubricating oil of the injection head 13. The injection head 13 ensures the uniformity of the lubricating oil injection through reciprocating movement, thereby ensuring the use effect of the lubricating oil.
