[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a flour milling machine for flour production, which has the following features:

[0017] Beneficial effects:

[0018] 1. In flour production, the design of the grinding mechanism enables wheat to be effectively pulverized into flour when passing through the mill. Driven by a motor, the rotating plate drives the rotating disc to rotate, which in turn drives the inner grinding blocks to rotate at high speed. This allows for efficient friction and compression of the raw materials, gradually turning the wheat into fine powder. The multi-group design of the grinding blocks ensures the uniformity and stability of the pulverization process, thereby controlling the particle size and ensuring the fineness of the final flour. In addition, the powder can be quickly passed through and discharged through the filter plate, effectively improving production efficiency and reducing time waste.

[0019] 2. The quick-release mechanism provides significant convenience when cleaning or replacing filter plates. Through the cooperation of the fixing rod and the fixing sleeve, along with the rotating limit sleeve, the locking block can smoothly slide out of the slot, thereby releasing the filter plate from its fixation. The arc-shaped design of the locking block matches the slot, making the disassembly operation smoother and avoiding the disadvantages of difficult and time-consuming disassembly in traditional equipment. When replacing the filter plate, the insertion of the fixing rod and the filter plate, as well as the action of the push spring, ensure that the locking block slides smoothly into the slot and is firmly fixed, greatly improving the speed and ease of filter plate replacement, thereby improving the operating efficiency of the entire production line.

[0020] 3. The beneficial effect of the positioning mechanism is to ensure the precise coordination and stable operation of each component. Through the design of the positioning block and positioning hole, the positioning mechanism can accurately control the rotation and positioning of the limit sleeve, avoiding loosening or displacement of the equipment during operation. The cooperation between the compression spring and the positioning block makes the positioning process smooth and reliable, ensuring the rapid installation and fixing of the filter plate. Through the rotation of the limit sleeve, the arc design of the positioning plate and positioning hole can ensure that the positioning block slides in smoothly, making the positioning more accurate, reducing equipment failures caused by improper installation, and improving the stability and service life of the equipment.

The system includes a groove 11, a rotating rod 12, a locking block 13, a locking groove 14, a limiting sleeve 15, an outer sleeve 16, a push spring 17, and a positioning mechanism. The fixing rod 9 is inserted into the filter plate 8 and the outer shell 2. The fixing sleeve 10 is located at the top of the fixing rod 9. Multiple sets of mounting grooves 11 are distributed on the outer wall of the fixing sleeve 10. The rotating rod 12 rotates within multiple sets of mounting grooves 11. The locking block 13 is located at the bottom of multiple sets of locking blocks 13. Multiple sets of locking grooves 14 are distributed on the outer wall of the fixing rod 9.

The push spring 17 is installed on the top surface of multiple sets of locking blocks 13 and connected to the inner wall of the outer sleeve 16.

[0031] The positioning mechanism includes movable holes 18, movable blocks 19, positioning blocks 20, compression springs 21, positioning plates 22, and positioning holes 23. Multiple sets of movable holes 18 are provided on the outer wall of the fixed sleeve 10. Movable blocks 19 slide within multiple sets of movable holes 18. Positioning blocks 20 are installed on the top of multiple sets of movable blocks 19. Compression springs 21 are installed on the inner side of multiple sets of positioning blocks 20 and connected to the outer wall of the fixed sleeve 10. Multiple sets of positioning plates 22 are provided on the bottom surface of the limiting sleeve 15. Positioning holes 23 are distributed on multiple sets of positioning plates 22.

[0032] A rotating frame 24 is provided on one side of the outer casing 2, and a rotating plate 25 is connected to the rotating frame 24. The arrangement of the rotating frame 24 and the rotating plate 25 allows the rotating plate to rotate flexibly, which is convenient for adjustment and operation, and improves the adaptability and stability of the equipment.

[0033] A material box 26 is installed on the rotating plate 25. A conveying groove 27 is opened on the inner side of the material box 26. The conveying groove 27 is connected to the outer shell 2. The design of the material box 26 and the conveying groove 27 ensures that the material can smoothly enter the inner shell 2 from the material box and flow through the conveying groove 27, thus ensuring the effective conveying of the material.

[0034] A discharge pipe 28 is installed on the outside of the outer shell 2. The discharge pipe 28 is located around the filter plate 8. The discharge pipe 28 can efficiently guide the processed material out of the outer shell 2, avoiding material accumulation or blockage and improving work efficiency.

[0035] The top inner surface of the fixed sleeve 10 is provided with a positioning rod 29, and the top end of the fixed rod 9 is provided with a positioning groove 30. Both the positioning rod 29 and the positioning groove 30 are polygonal. The polygonal design of the positioning rod 29 and the positioning groove 30 ensures the accuracy of positioning, prevents the loosening or misalignment of parts, and improves the stability of the equipment.

[0036] The outer wall of the limiting sleeve 15 is provided with a clearance groove 31. There are multiple sets of clearance grooves 31, and the number is the same as the number of sets of locking blocks 13. The design of clearance grooves 31 and locking blocks 13 makes the disassembly and installation of the equipment more convenient. The operation process is simplified by cooperating with the same number of locking blocks and clearance grooves.

[0037] The outer sides of the multiple sets of positioning blocks 20 and positioning holes 23 are all set in an arc shape. The arc-shaped design of the positioning blocks 20 and positioning holes 23 improves the fitting accuracy of the parts, ensures a smoother installation and disassembly process, and increases the reliability and durability of the equipment.

[0038] In this embodiment, the motor 3 is fixed to one side of the outer casing 2. The motor 3 is connected to the outer casing 2 via a drive shaft 4. The output end of the motor 3 directly drives the drive shaft 4 to rotate. The rotation of the drive shaft 4 causes the mounting plate 5 to rotate. Multiple sets of rotating plates 6 are distributed on the mounting plate 5. The rotation of the rotating plates 6 causes the grinding blocks 7 to rotate as well. The grinding blocks 7 are multiple sets of crushing elements installed inside the outer casing 2. When the rotating plates 6 drive the grinding blocks 7 to rotate, the raw material is gradually compressed, rubbed, and crushed. Through continuous friction and pressure, the raw material is ground into powder. The powder will eventually be screened and discharged through the filter plate 8 inside the outer casing 2. The design of the grinding mechanism can effectively grind the raw material and control the particle size of the powder, ensuring the fineness of the flour. When it is necessary to clean or replace the filter plate 8, the rotating limit sleeve 15 rotates the multiple sets of clearance grooves 31 into multiple sets of locking... The outer side of block 13 is removed, thereby releasing the contact between the limiting sleeve 15 and the top surface of the multiple sets of locking blocks 13. Then, the fixing rod 9 is pulled out of the fixing sleeve 10. Through the arc design of the multiple sets of locking blocks 13 and the slot 14, the locking blocks 13 slide smoothly out of the slot 14. Then the filter plate 8 can be disassembled. When the filter plate 8 needs to be installed, the fixing rod 9 is inserted into the filter plate 8 and the outer shell 2. The fixing sleeve 10 is inserted into the top of the fixing rod 9. The inclined surface at the top of the rod pushes the multiple sets of locking blocks 13 outward. The rotating rod 12 rotates and squeezes the push spring 17. When the locking block 13 moves into the slot 14, the push spring 17 pushes the locking block 13 into the slot 14. Then, the limiting sleeve 15 is rotated so that the multiple sets of relief grooves 31 are disengaged from the outer side of the locking block 13. The inner side of the limiting sleeve 15 abuts against the outer wall of the locking block 13, completing the installation.

[0039] More specifically, when the limiting sleeve 15 rotates, multiple sets of positioning plates 22 move simultaneously. Through the arc design of multiple sets of positioning holes 23 and the outer side of the positioning block 20, the positioning block 20 can squeeze the compression spring 21 under a certain force, causing the positioning block 20 to disengage from the positioning hole 23, and causing the next set of positioning blocks 20 to slide into the positioning hole 23, so that the limiting sleeve 15 can rotate for positioning.

[0040] In summary, during the use or operation of the overall equipment: Motor 3 is fixed to one side of the outer casing 2. Motor 3 is connected to the outer casing 2 via drive shaft 4. The output end of motor 3 directly drives drive shaft 4 to rotate. The rotation of drive shaft 4 drives mounting plate 5 to rotate. Multiple sets of rotating plates 6 are distributed on mounting plate 5. The rotation of rotating plates 6 causes grinding blocks 7 to rotate as well. Grinding blocks 7 are multiple sets of pulverizing elements installed inside the outer casing 2. When rotating plates 6 drive grinding blocks 7 to rotate, the raw material is gradually compressed, rubbed, and pulverized. Through continuous friction and pressure, the raw material is ground into powder. The powder will eventually be screened and discharged through filter plate 8 inside the outer casing 2. The design of the grinding mechanism can effectively grind the raw material and control the particle size of the pulverized powder, ensuring the fineness of the flour. When it is necessary to clean or replace filter plate 8, rotating limit sleeve 15 will rotate multiple sets of clearance grooves 31. Move the multiple sets of locking blocks 13 to the outside, thereby releasing the contact between the limiting sleeve 15 and the top surface of the multiple sets of locking blocks 13. Then, pull out the fixing rod 9 from the fixing sleeve 10. Through the arc design of the multiple sets of locking blocks 13 and the slot 14, the locking blocks 13 slide smoothly out of the slot 14. Then the filter plate 8 can be disassembled. When the filter plate 8 needs to be installed, insert the fixing rod 9 into the filter plate 8 and the outer shell 2, and insert the fixing sleeve 10 into the top of the fixing rod 9. The inclined surface set at the top of the rod pushes the multiple sets of locking blocks 13 to move outward. By rotating the rotating rod 12 and pressing the push spring 17, when the locking block 13 moves into the slot 14, the push spring 17 pushes the locking block 13 to engage in the slot 14. Then rotate the limiting sleeve 15 so that the multiple sets of clearance slots 31 disengage from the outside of the locking block 13 and abut against the outer wall of the locking block 13 through the inner side of the limiting sleeve 15, thus completing the installation.

[0041] When the limiting sleeve 15 rotates, multiple sets of positioning plates 22 move simultaneously. Through the arc design of multiple sets of positioning holes 23 and the outer side of the positioning block 20, the positioning block 20 can squeeze the compression spring 21 under a certain force, causing the positioning block 20 to disengage from the positioning hole 23, and causing the next set of positioning blocks 20 to slide into the positioning hole 23, so that the limiting sleeve 15 can rotate for positioning.

[0042] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.

The scope of this utility model is defined by the appended claims and their equivalents.
