Description

Technical Field

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

[0002] In the flour processing industry, flour purifiers are key equipment for flour grading, and their structural design and functionality directly affect processing efficiency and product quality. However, flour purifiers currently on the market still have many technical defects in practical applications. These problems not only affect the service life of the equipment but also reduce production efficiency.

[0003] The primary problem is the insufficient stability of the discharge pipe. Existing powder cleaning machines have significant defects: First, the vibration and throwing generated during operation cause the machine body to move back and forth continuously, affecting the stability of the equipment; second, the discharge pipe resonates with the vibration of the machine body, increasing the risk of pipe detachment. Frequent vibration may also cause wear and damage at the pipe joints. This structural design deficiency not only affects the reliability of the equipment but may also lead to safety hazards and increased maintenance costs.

[0004] More notably, the lack of airflow conveying speed adjustment function presents significant problems with existing powder cleaning machines: First, the airflow speed generated by the fan is usually a fixed value and cannot be adjusted according to different needs; second, a single conveying speed is difficult to adapt to the conveying needs of materials with different fineness; third, a fixed airflow speed may lead to low conveying efficiency or material loss. This design deficiency not only limits the applicability of the equipment but may also affect product quality.

[0005] Most critically, the speed regulation structure lacks reliability. Although some improved powder cleaning machines have added speed regulation functions, their structures have obvious defects: First, the simple speed regulation structure is easily affected by air pressure impact and becomes loose. Second, equipment vibration may cause the speed regulation device to shift, affecting the speed regulation effect. Loose structure will cause the preset conveying speed to change, affecting production stability. This structural design deficiency not only affects the reliability of the equipment but also increases the maintenance frequency. Utility Model Content

[0019] Beneficial effects:

[0020] 1. The conveying device constructs a stable conveying system through the precise coordination of the conveying pipe, output pipe, connecting pipe and fan.

[0033] Please see Figures 1-6 A flour purifying machine includes a purifying machine 1. A conveying device is installed on the lower side of the purifying machine 1. The conveying device includes a conveying pipe 2, an output pipe 3, a connecting pipe 4, and a fan 5. The output pipe 3 is fixedly connected to the bottom end of the purifying machine 1, and the connecting pipe 4 is fixedly connected to the top of the conveying pipe 2, with the bottom end of the output pipe 3 slidingly inserted into the connecting pipe 4. The fan 5 is installed on one side of the purifying machine 1. A regulating device is provided at one end of the conveying pipe 2. The regulating device includes an installation pipe 6, sliding blocks 7, a connecting rod 8, a control sleeve 9, a control rod 10, a control sleeve 11, a moving spring 12, a fixed block 13, a moving groove 14, and a pusher 15. The installation pipe 6 is connected to the output end of the fan 5. Multiple sliding blocks 7 are slidably installed inside the installation pipe 6. The control sleeve 9 is fixedly connected to the control sleeve 11 through the connecting rod 8. The control rod 10 is fixedly connected to one end of the pusher frame 15. The control sleeve 9 is movably sleeved on the outside of the control rod 10 via threads. The two ends of the control sleeve 11 are rotatably connected to the conveying pipe 2 and the installation pipe 6, respectively. The two ends of the moving spring 12 are connected to the inner walls of the fixed block 13 and the moving groove 14, respectively. The fixed block 13 is fixedly installed inside the installation pipe 6. The moving groove 14 is opened on one side of the sliding block 7. A locking mechanism is installed on the outside of the conveying pipe 2. The locking mechanism includes a push sleeve 16, a longitudinal plate 17, a support block 18, a support plate 19, a rotating plate 20, and a rotating groove 21. The push sleeve 16 is slidably installed on the outside of the conveying pipe 2. The longitudinal plate 17 is fixedly connected to one side of the push sleeve 16. The support plate 19 and the support block 18 are fixedly installed on one side of the longitudinal plate 17. The rotating plate 20 is rotatably sleeved on the outside of the conveying pipe 2. The rotating groove 21 is opened on the rotating plate 20.

[0034] A base 22 is provided below the powder cleaning machine 1. A damper 23 is detachably provided on the base 22. A piston rod 24 is connected to the output end of the damper 23. A connecting frame 25 is installed below the powder cleaning machine 1. The top end of the piston rod 24 is detachably connected to the connecting frame 25. A spring 26 is sleeved on the outside of the damper 23 and the piston rod 24. The two ends of the spring 26 are connected to the base 22 and the connecting frame 25 respectively.

[0035] The base 22 is detachably provided with a mounting seat 27, which is installed on the outside of the delivery pipe 2.

[0036] In this embodiment, when the equipment is in use, the cleaning machine 1 will vibrate up and down, causing the cleaning machine 1 to drive the conveying pipe 2 connected to the lower end to slide up and down along the inner wall of the connecting pipe 4. This prevents the conveying pipe 2 and other components from vibrating up and down with the cleaning machine 1, reducing damage to the conveying pipe 2. At the same time, the cleaning machine 1 drives the piston rod 24 to move through the connecting frame 25. During the movement of the piston rod 24, the hydraulic oil is squeezed, and the oil is forced to flow through the throttle orifice, thereby generating a damping force. At the same time, the movement of the piston rod 24 also causes the connecting frame 25 and the base 22 to cooperate in compressing the spring 26 and storing energy in the spring 26, thus generating a damping force. The presence of the spring 26 can effectively control the speed of the entire motion. When the external force disappears, the compressed spring 26 begins to release the stored energy. The spring 26 pushes the piston rod 24 back to its original position. During the return process, the return oil needs to pass through the throttling channel. The damping force generated ensures that the piston rod 24 can return to its original position smoothly, and finally restores the entire system to its initial state. In practical applications, the system can continuously withstand reciprocating motion, continuously convert energy, always maintain a good shock absorption effect, maintain a stable working state, achieve reliable protection of the equipment, and reduce the impact of vibration on the output pipe 3 and the connecting pipe 4, thereby reducing wear.

[0037] Please see Figures 3-6 As a further implementation of the overall device: the sliding block 7 is provided with multiple moving holes 28.

[0038] A push plate 29 is fixedly provided on the outer side of the push sleeve 16.

[0039] A push spring 30 is connected to one side of the push sleeve 16, and a bearing 31 is detachably provided on one side of the rotating plate 20. The other end of the push spring 30 is connected to the bearing 31, which is a thrust bearing 31.

[0040] Multiple sliders 32 are fixedly provided on the outer side of the pusher frame 15, and multiple grooves 33 are provided on the inner wall of the mounting tube 6, with the sliders 32 slidably disposed in the grooves 33.

[0041] Multiple locking grooves 34 are provided on the outer side of the conveying pipe 2, and multiple locking rods 35 are slidably provided on the side wall of the control sleeve 11. A return spring 36 is provided on the outer side of the control sleeve 11. One end of the locking rod 35 is inserted into the locking groove 34, and the other end of the locking rod 35 is connected to the outer wall of the control sleeve 11 through the return spring 36.

[0042] More specifically, when the airflow delivery speed needs to be flexibly adjusted according to requirements, firstly, the rotating plate 20 is rotated, causing the bearing 31 mounted on one side to rotate. Simultaneously, the rotating plate 20 moves the rotating groove 21. When the rotating groove 21 moves to the position corresponding to the support plate 19 and the support block 18, the push plate 29 pushes the push sleeve 16 to slide. The push sleeve 16 and the bearing 31 cooperate to compress the push spring 30. Simultaneously, the push sleeve 16 drives the support plate 19 and the support block 18 to slide through the longitudinal plate 17, causing the support block 18 to slide into the rotating groove 21. When the push spring 30 is compressed to its limit, the support block 18 completely passes through the rotating groove 21 and moves to the other side of the rotating plate 20. Then, the rotating plate 20 is rotated again, causing it to move the rotating groove 21 to a position where it no longer intersects with the support block 18 and the support plate 19. At the corresponding position, the longitudinal plate 17 and the support block 18 cooperate to limit the push sleeve 16 to one side of the rotating plate 20, so that the push sleeve 16 no longer limits the locking rod 35. Then, the control sleeve 11 is rotated in the forward direction, so that the control sleeve 11 drives the multiple locking rods 35 slidably set on the side wall to move. Then, the inner wall of the locking groove 34 presses against one end of the locking rod 35. Due to the rounded corner design at the end of the locking rod 35 and the edge of the inner wall of the locking groove 34, one end of the locking rod 35 slides out of the locking groove 34, and the other end drives the return spring 36 to stretch. At the same time, the control sleeve 11 drives the control sleeve 9 to rotate in the forward direction through the connecting rod 8. Since the control sleeve 9 and the control rod 10 are connected by threads, and the slider 32 and the sliding groove 33 limit the push frame 15, the push frame 15 and the control rod 10 will not rotate. The control rod 10 drives the pusher 15 to slide, causing the slider 32 to slide along the groove 33. The pusher 15 has a unique conical design. Then, the pusher 15 pushes multiple sliding blocks 7 outwards simultaneously, causing the sliding blocks 7 to drive the movable groove 14 on one side to slide along the fixed block 13. This causes the inner wall of the movable groove 14 to stretch the movable spring 12. Simultaneously, the sliding blocks 7 drive multiple movable holes 28 to move outwards. The movement of the sliding blocks 7 and the movable holes 28 changes the flow area at corresponding positions inside the mounting tube 6, thereby adjusting the airflow delivery speed. After proper adjustment, the control sleeve 11 stops rotating, and the reset spring 36 drives the locking rod 35 to slide into the corresponding locking groove 34. Then, the rotating plate 20 is rotated again, causing the rotating plate 20 to... The rotating groove 21 and bearing 31 rotate. When the rotating groove 21 moves again to the position corresponding to the support block 18 and support plate 19, the push spring 30 pushes the push sleeve 16 to slide the push plate 29 back to its original position. The push sleeve 16 will also drive the support plate 19 and support block 18 to slide back to their original position via the longitudinal plate 17. After the push spring 30 is fully reset, the support block 18 and support plate 19 are respectively on both sides of the rotating plate 20. Then the rotating plate 20 continues to rotate, causing the rotating groove 21 to move to a position that does not correspond to the support block 18 and support plate 19. Then the support plate 19 and support block 18, together with the longitudinal plate 17, limit the push sleeve 16 to one side of the rotating plate 20, so that the inner wall of the push sleeve 16 again limits the outer end of the locking rod 35. Then the locking rod 35 and the locking groove 34 cooperate to lock the control sleeve 11, preventing the control sleeve 11 from rotating.This ensures structural stability after the airflow speed is adjusted, thereby guaranteeing stable equipment operation.

[0043] In summary, during the use or operation of the overall equipment: When the equipment is in use, the cleaning machine 1 will vibrate up and down, causing the lower connected conveying pipe 2 to slide up and down along the inner wall of the connecting pipe 4. This prevents the conveying pipe 2 and other components from vibrating up and down with the cleaning machine 1, reducing damage to the conveying pipe 2. At the same time, the cleaning machine 1 drives the piston rod 24 to move through the connecting frame 25. During the movement of the piston rod 24, the hydraulic oil is squeezed, and the oil is forced to flow through the throttle orifice, thereby generating a damping force. At the same time, the movement of the piston rod 24 also causes the connecting frame 25 and the base 22 to cooperate in compressing the spring 26 and storing energy in the spring 26. The presence of damping force can effectively control the speed of the entire motion. When the external force disappears, the compressed spring 26 begins to release the stored energy. The spring 26 pushes the piston rod 24 back to its original position. During the return process, the return oil needs to pass through the throttling channel. The generated damping force ensures that the piston rod 24 can return to its original position smoothly, and finally restores the entire system to its initial state. In practical applications, the system can continuously withstand reciprocating motion, continuously convert energy, always maintain a good shock absorption effect, maintain a stable working state, achieve reliable protection of the equipment, and reduce the impact of vibration on the output pipe 3 and the connecting pipe 4, thereby reducing wear.

[0044] When the airflow delivery speed needs to be flexibly adjusted according to requirements, first rotate the rotating plate 20, causing the bearing 31 mounted on one side to rotate. Simultaneously, the rotating plate 20 moves the rotating groove 21. When the rotating groove 21 moves to the position corresponding to the support plate 19 and the support block 18, the push plate 29 pushes the push sleeve 16 to slide. The push sleeve 16 and the bearing 31 cooperate to compress the push spring 30. At the same time, the push sleeve 16 drives the support plate 19 and the support block 18 to slide through the longitudinal plate 17, causing the support block 18 to slide into the rotating groove 21. When the push spring 30 is compressed to its limit, the support block 18 completely passes through the rotating groove 21 and moves to the other side of the rotating plate 20. Then, continue rotating the rotating plate 20, causing it to move the rotating groove 21 to a position no longer corresponding to the support block 18 and the support plate 19. Then, the longitudinal plate 17 and the support block 18 cooperate to limit the push sleeve 16 to one side of the rotating plate 20, so that the push sleeve 16 no longer limits the locking rod 35. Then, the control sleeve 11 is rotated in the forward direction, so that the control sleeve 11 drives the multiple locking rods 35 slidably set on the side wall to move. Then, the inner wall of the locking groove 34 presses against one end of the locking rod 35. Due to the rounded corner design at the end of the locking rod 35 and the edge of the inner wall of the locking groove 34, one end of the locking rod 35 slides out of the locking groove 34, and the other end drives the return spring 36 to stretch. At the same time, the control sleeve 11 drives the control sleeve 9 to rotate in the forward direction through the connecting rod 8. Since the control sleeve 9 and the control rod 10 are connected by threads, and the slider 32 and the slide groove 33 limit the push frame 15, the push frame 15 and the control rod 10 will not rotate. Then the control rod 1 The pusher 15 slides, causing the slider 32 to slide along the groove 33. The pusher 15 has a unique conical design. Then, the pusher 15 pushes multiple sliding blocks 7 outwards simultaneously, causing the sliding blocks 7 to slide along the fixed block 13 via the movable groove 14 on one side. This causes the movable spring 12 to stretch along the inner wall of the movable groove 14. Simultaneously, the sliding blocks 7 cause multiple movable holes 28 to move outwards. The movement of the sliding blocks 7 and the movable holes 28 changes the flow area at corresponding positions inside the mounting tube 6, thereby adjusting the airflow delivery speed. After proper adjustment, the control sleeve 11 stops rotating, causing the reset spring 36 to slide the locking rod 35 into the corresponding locking groove 34. Then, the rotating plate 20 is rotated again, causing the rotating plate 20 to... The rotating groove 21 and bearing 31 rotate. When the rotating groove 21 moves again to the position corresponding to the support block 18 and support plate 19, the push spring 30 pushes the push sleeve 16 to drive the push plate 29 to slide back to its original position. The push sleeve 16 will also drive the support plate 19 and support block 18 to slide back to their original position through the longitudinal plate 17. After the push spring 30 is fully reset, the support block 18 and support plate 19 are respectively on both sides of the rotating plate 20. Then the rotating plate 20 continues to rotate, causing the rotating groove 21 to move to a position that does not correspond to the support block 18 and support plate 19. Then the support plate 19 and support block 18, together with the longitudinal plate 17, limit the push sleeve 16 to one side of the rotating plate 20, so that the inner wall of the push sleeve 16 again limits the outer end of the locking rod 35. Then the locking rod 35 and locking groove 34 cooperate to lock the control sleeve 11, preventing the control sleeve 11 from rotating.This ensures structural stability after the airflow speed is adjusted, thereby guaranteeing stable equipment operation.
