Description

Technical Field

[0001] This utility model relates to the field of flour cleaning machine technology, and more specifically, it relates to a flour cleaning machine for flour processing. Background Technology

[0002] Existing flour purifiers typically employ fixed or simple adjustment mechanisms, lacking precise fine-tuning capabilities. These mechanisms often use simple bolt fixation or crude slide groove designs, requiring the fixing device to be loosened, the component manually moved, and then re-locked during adjustment. This process is cumbersome and makes precise positioning difficult. In particular, in flour processing environments, the equipment surface is often covered with dust, causing the adjustment components to slide poorly and further increasing the difficulty of adjustment.

[0003] Traditional dust collectors typically use multi-point bolt fixing or complex snap-fit ​​structures for their collection boxes. The installation and disassembly process requires operation of multiple connection points. This design not only increases operation time but also makes it easy for operational errors to lead to incomplete connections or damage to connecting parts. In dusty working environments, the connection structure is also easily contaminated, further increasing the difficulty of operation.

[0004] Frequent adjustments and disassembly accelerate the wear and tear of equipment components, increasing maintenance frequency and parts replacement costs. Unplanned downtime caused by poor equipment stability also increases the workload of maintenance personnel and raises labor costs. Utility Model Content

[0030] Please see Figures 1-5A flour cleaning machine for flour processing includes a lifting plate 1, a horizontal adjustment mechanism, a housing locking mechanism, and a locking auxiliary mechanism. The horizontal adjustment mechanism includes a moving plate 2, a threaded block 3, a lead screw 4, a handle 5, a guide rod 6, and a guide sleeve 7. The guide rod 6 is fixedly installed at the top end of the lifting plate 1, and the guide sleeve 7 is installed at the bottom end of the moving plate 2, sliding and guiding the guide rod 6. The lead screw 4 is rotatably installed at the top of the lifting plate 1, and the threaded block 3 is installed at the bottom end of the moving plate 2, with the lead screw 4 threadedly connected to the threaded block 3. The handle 5 is installed at one end of the lead screw 4, and the housing locking mechanism... The mechanism includes a collection box 8, a side plate 9, a support plate 10, a locking tube 11, a locking rod 12, a rotating sleeve 13, a rotary push groove 14, an extension rod 15, and a slot 16. The side plate 9 is installed on the side of the collection box 8, the support plate 10 is installed on the side of the moving plate 2, the locking tube 11 is installed on the side plate 9, the locking rod 12 is installed on the support plate 10, the rotating sleeve 13 is rotatably limited and installed on the outer wall of the locking tube 11, and the extension rod 15 is installed on the side wall of the locking tube 11. The rotary push groove 14 on the inner wall of the rotating sleeve 13 pushes the extension rod 15 into the slot 16.

[0031] In this embodiment, the operator rotates the handle 5, causing the lead screw 4 to rotate. The threaded block 3 moves along the thread as the lead screw 4 rotates, pushing the moving plate 2 to slide on the guide rod 6. The guide sleeve 7 plays a guiding role on the guide rod 6, ensuring that the moving plate 2 moves smoothly laterally. By adjusting the rotation direction and angle of the handle 5, the lateral position of the moving plate 2 can be precisely controlled, thereby adjusting the working position of the powder cleaning machine. When the collection box 8 needs to be connected to the moving plate 2, the snap-fit ​​rod 12 is aligned with the snap-fit ​​tube 11, and the rotating sleeve 13 is rotated. The inner wall's rotary push groove 14 pushes the extension rod 15 to move, so that the extension rod 15 extends into the snap-fit ​​groove 16 on the snap-fit ​​rod 12, forming a mechanical lock. The connecting plate 30 enhances the connection stability between the snap-fit ​​tube 11 and the side plate 9, ensuring that the structure will not loosen during the snap-fit ​​process. The rotating sleeve 13 is rotated in the opposite direction, and the counter-push spring 31 pushes the extension frame away from the snap-fit ​​groove 16.

[0032] The snap-fit ​​auxiliary mechanism includes a rotating block 17, a rotating ring 18, a fixed frame 19, a pressure spring frame 20, and a pressure groove 21. The rotating block 17 is installed on the top end of the rotating sleeve 13, the rotating ring 18 is installed on the rotating block 17, the pressure groove 21 is set on the rotating ring 18, the fixed frame 19 is installed on the outer wall of the snap-fit ​​tube 11, and the pressure spring frame 20 is installed on the fixed frame 19. The pressure spring frame 20 extends into the pressure groove 21 step by step, so that the rotating block 17 and the rotating sleeve 13 rotate stably.

[0033] In this embodiment, when the rotating sleeve 13 rotates, it drives the rotating block 17 and the rotating ring 18 at the top to rotate together. The pressure groove 21 on the rotating ring 18 cooperates with the compression spring frame 20 on the fixed frame 19. The compression spring frame 20 extends into the pressure groove 21 step by step to form a stepped positioning mechanism, so that the rotating sleeve 13 can stay stably at a specific angle, preventing accidental rotation caused by vibration and ensuring the reliability of the snap-fit ​​state.

[0034] Please see Figures 1-5 As a supplementary embodiment of a flour cleaning machine for flour processing, which includes a horizontal adjustment mechanism, a box locking mechanism, and a locking auxiliary mechanism: A scissor frame assembly 22 is installed at the bottom end of the lifting plate 1, and a base plate 23 is installed at the bottom end of the scissor frame assembly 22. Bottom wheels 24 are installed at the four ends of the bottom end of the base plate 23. A push handle 25 is installed on the side of the base plate 23. An inclined cavity hopper 26 is installed at the top end of the moving plate 2. One end of the inclined cavity hopper 26 is connected to the box, and a fan assembly 27 is installed at one end of the inclined cavity hopper 26. A hose 28 is installed on one side of the fan assembly 27, and a powder suction hopper 29 is installed at one end of the hose 28. A connecting plate 30 is installed at the bottom end of the side wall of the locking pipe 11, and the connecting plate 30 is installed on the side plate 9. A push spring 31 is installed inside the locking groove 16, and the extension frame extends into the locking groove 16 to compress the push spring 31.

[0035] More specifically, the operator pushes the device to the appropriate position using the push handle 25. The bottom wheel 24 provides convenient movement. According to processing needs, the operator rotates the handle 5 to adjust the lateral position of the moving plate 2 so that the inclined cavity hopper 26 is aligned with the box body. The collection box 8 is connected to the moving plate 2 through the box body locking mechanism. The rotating sleeve 13 drives the extension rod 15 to lock into the slot 16. The locking auxiliary mechanism ensures a stable connection. The fan assembly 27 is started, and negative pressure is generated through the hose 28 and the powder suction hopper 29 to suck impurities and powder in the flour into the collection box 8 through the inclined cavity hopper 26. The height of the lifting plate 1 is adjusted by the scissor frame assembly 22 as needed to adapt to different processing requirements. After the powder cleaning is completed, the rotating sleeve 13 rotates in the opposite direction to release the extension rod 15 and disassemble the collection box 8 for cleaning.

[0036] In summary, when the overall equipment is in use or running: when the lateral adjustment mechanism needs to be running, the operator turns the handle 5, which drives the lead screw 4 to rotate. The threaded block 3 moves along the thread as the lead screw 4 rotates, pushing the moving plate 2 to slide on the guide rod 6. The guide sleeve 7 plays a guiding role on the guide rod 6, ensuring that the moving plate 2 moves smoothly laterally. By adjusting the rotation direction and angle of the handle 5, the lateral position of the moving plate 2 can be precisely controlled, thereby adjusting the working position of the powder cleaning machine.

[0037] When the box locking mechanism is in operation, when the collection box 8 needs to be connected to the moving plate 2, the locking rod 12 is aligned with the locking tube 11, the rotating sleeve 13 is rotated, and the inner wall's rotary push groove 14 pushes the extension rod 15 to move, so that the extension rod 15 extends into the locking groove 16 on the locking rod 12, forming a mechanical lock. The connecting plate 30 enhances the connection stability between the locking tube 11 and the side plate 9, ensuring that the structure will not loosen during the locking process. The rotating sleeve 13 is rotated in the opposite direction, and the counter-push spring 31 pushes the extension frame away from the locking groove 16.

[0038] When the locking auxiliary mechanism is in operation, the rotating sleeve 13 rotates, causing the top rotating block 17 and rotating ring 18 to rotate together. The pressure groove 21 on the rotating ring 18 cooperates with the compression spring frame 20 on the fixed frame 19. The compression spring frame 20 extends into the pressure groove 21 step by step to form a stepped positioning mechanism, so that the rotating sleeve 13 stays stably at a specific angle, preventing accidental rotation caused by vibration and ensuring the reliability of the locking state.

[0039] The operator pushes the device to the appropriate position using the push handle 25. The bottom wheel 24 provides convenient movement. According to the processing needs, the operator rotates the handle 5 to adjust the lateral position of the moving plate 2 so that the inclined cavity hopper 26 is aligned with the box body. The collection box 8 is connected to the moving plate 2 through the box body locking mechanism. The rotating sleeve 13 drives the extension rod 15 to lock into the slot 16. The locking auxiliary mechanism ensures a stable connection. The fan assembly 27 is started, and negative pressure is generated through the hose 28 and the powder suction hopper 29 to suck impurities and powder in the flour into the collection box 8 through the inclined cavity hopper 26. The height of the lifting plate 1 is adjusted by the scissor frame assembly 22 as needed to adapt to different processing requirements. After the powder cleaning is completed, the rotating sleeve 13 rotates in the opposite direction to release the extension rod 15 and disassemble the collection box 8 for cleaning.
