[0002] Flour mills are widely used in the powder processing of mineral products in the fields of metallurgy, building materials, chemical industry, mining, etc. According to the fineness of the materials to be ground and the fineness of the discharged materials, flour mills can be divided into six types: vertical swing flour mills, high-pressure hanging roller flour mills, high-pressure micro-powder flour mills, straight-through centrifugal flour mills, super-pressure trapezoidal flour mills, and three-ring medium-speed flour mills.
[0003] The existing flour mills generally use cylinders to drive the main grinding roll to rotate close to the secondary grinding roll, so as to achieve the purpose of crushing materials. However, only rotating the main grinding roll results in a slight gap between the main grinding roll and the secondary grinding roll, and the materials cannot be ground into fine powder, and the grinding effect is average.

Both ends of the main grinding roll are provided with bearing seats. A rotating ring is arranged at the upper end of the bearing seat, and a rotating shaft is arranged inside the rotating ring. A preliminary adjustment structure is arranged outside the bearing seat. Both ends of the secondary grinding roll are provided with bearing sleeves. A connecting piece is arranged at the upper end of the bearing sleeve. One end of the connecting piece is connected to the rotating shaft, and the other end of the connecting piece is connected to a fine adjustment structure. The fine adjustment structure contains a driving motor. Springs are arranged between the bearing seats and the bearing sleeves.
[0007] In the above solution, through the setting of the driving motor, the main grinding roll is first driven to rotate by the preliminary adjustment structure, so that the main grinding roll approaches the secondary grinding roll, and then the driving motor is used to finely adjust the slight gap between the main grinding roll and the secondary grinding roll to achieve the close contact between the main grinding roll and the secondary grinding roll, thus solving the problem of non-precise grinding.
[0008] The preliminary adjustment structure contains a cylinder. A fixed block is connected to the piston rod of the cylinder, and a rotating arm is fixedly connected between the fixed block and the rotating shaft.
[0009] In the above solution, through the setting of the cylinder, when the cylinder is started, the piston rod of the cylinder moves upward to drive the fixed block to move, and drives the rotating arm to rotate, so as to realize the rotation of the main grinding roll close to the secondary grinding roll.
[0010] The connecting member includes a front fork. The vertical segments arranged in parallel in the front fork are located on both sides of the vicinity of the edge of the rotating shaft. The rotating shaft is located inside the opening of the front fork, and both ends of the rotating shaft pass through the corresponding vertical segments and extend to the outside of the front fork. The other end of the front fork is connected to a rotating rod, and the front fork is rotatably connected to the rotating rod.
[0011] In the above solution, through the arrangement of the front fork and the rotating rod, the driving motor drives the rotating rod to move in the horizontal direction, so as to make a small adjustment to the secondary grinding roller.
[0012] The lead screw of the driving motor is connected to the rotating rod through a coupling. A plurality of disc springs are arranged on one side of the rotating rod close to the driving motor.

The fine adjustment structure includes a driving motor 7. Springs 8 are provided between the bearing seat 3 and the bearing sleeve 5. First, the preliminary adjustment structure drives the main grinding roller 1 to rotate, so that the main grinding roller 1 approaches the auxiliary grinding roller 2. Then, the driving motor 7 is used to finely adjust the minute gap between the main grinding roller 1 and the auxiliary grinding roller 2, realizing the close contact between the main grinding roller 1 and the auxiliary grinding roller 2, and greatly improving the fineness of grinding.
[0025] The preliminary adjustment structure includes a cylinder 9. A fixed block 10 is connected to the piston rod of the cylinder 9. A swing arm 11 is fixedly connected between the fixed block 10 and the rotating shaft 6. When the cylinder 9 is started, the piston rod of the cylinder 9 moves vertically upward, driving the fixed block 10 to move in the vertical direction and driving the swing arm 11 to rotate around the rotating shaft 6, thereby realizing the rotation of the main grinding roller 1 to approach the auxiliary grinding roller 2.
[0026] The connecting piece includes a front fork 12. The vertical sections arranged in parallel in the front fork 12 are located on both sides of the edge near the rotation axis 6.

The driving motor 7 drives the rotating rod 13 to move in the horizontal direction, driving the secondary grinding roller 2 to make small adjustments.
[0027] The lead screw of the driving motor 7 is connected to the rotating rod 13 through a coupling. A plurality of disc springs 14 are arranged on the side of the rotating rod 13 close to the driving motor 7.
[0028] First, start the cylinder 9. The piston rod of the cylinder 9 moves vertically upward, driving the fixed block 10 to move in the vertical direction, driving the swing arm 11 to rotate around the rotation axis 6, so as to realize the main grinding roller 1 rotating close to the secondary grinding roller 2. Then, fine-tune the fine gap between the main grinding roller 1 and the secondary grinding roller 2 through the driving motor 7. The lead screw of the driving motor 7 rotates, driving the rotating rod 13 to rotate along the direction of the lateral elongation of the lead screw, so that the secondary grinding roller 2 makes a small and precise movement, and finally realizes the close contact between the main grinding roller 1 and the secondary grinding roller 2.
