Description

Technical Field

[0001] The utility model relates to the technical field of flour processing, and more particularly to a screening device for flour processing. Background Art

[0002] Flour is a common food ingredient, mainly made from wheat, but can also be made from other grains such as barley, rye, corn, etc. Flour is an important source of carbohydrates for the human body, but it also loses some nutrients due to its processing methods (such as refining). Whole wheat flour contains more dietary fiber, B vitamins and minerals than refined flour.

[0003] When screening wheat, the existing screening device for flour production needs to screen out the granular impurities in the wheat to improve the quality of flour production. However, the existing screening device has a complex structure and a high failure rate. The hinged shaft is prone to friction loss during rotation, resulting in a low energy conversion rate during the screening process, prone to noise, and affecting the working environment.

The lubrication pipe 10 is provided with a movable ring 13 in the movable groove 11, and lubrication holes 14 are provided on the lubrication pipe 10 and the connecting sleeve 7. An oil filling pipe 15 is threadedly connected to the lubrication pipe 10, and an oil filling hole 16 is provided on the oil filling pipe 15. The driving device includes a driving motor 17, and pulleys 18 are provided on the motor shaft of the driving motor 17 and the driving rod 4. A transmission belt 19 is provided between the pulleys 18. Support pulleys 20 are symmetrically provided on the screening frame 2, and the screening net 8 is slidably set on the support pulley 20. A blanking plate 21 is provided on the screening frame 2.

[0030] In this embodiment, when in use, wheat for flour processing is placed on the screening net 8, and the drive motor 17 is started. The drive motor 17 drives the drive rod 4 to rotate through the cooperation of the pulley 18 and the transmission belt 19, and the eccentric rod 5 is driven to rotate by the drive rod 4. The rotation of the eccentric rod 5 drives the connecting rod 6 to rotate, and the screening net 8 is driven by the connecting rod 6 to reciprocate on the supporting pulley 20 to screen the wheat and filter out large particles of stones and other impurities. The wheat is recovered through the blanking plate 21.

[0031] See also Figure 3-Figure 5 As an implementation method of the oil filling pipe 15 and the lubrication pipe 10: a moving spring 22 is provided between the moving groove 11 and the moving ring 13, a piston rod 23 is provided on the oil filling pipe 15, a handle 24 is provided at one end of the piston rod 23, and a piston plate 25 is provided at the other end, an oil filling spring 26 is provided between the piston plate 25 and the oil filling pipe 15, and an exhaust hole 27 is provided on the oil filling pipe 15.

[0032] More specifically, during screening, the connecting rod 6 drives the connecting sleeve 7 to rotate on the connecting frame 9. When maintenance is required between the connecting frame 9 and the connecting sleeve 7, the lubrication tube 10 is pressed, and the lubrication tube 10 moves on the movable ring 13 and squeezes the movable spring 22, so that the lubrication hole 14 of the connecting sleeve 7 and the lubrication hole 14 of the lubrication tube 10 are aligned. Subsequently, the lubricating oil flows out through the lubrication tube 10 to between the connecting sleeve 7 and the connecting frame 9 under the pressure in the oil filling tube 15, lubricating the connecting frame 9 and the connecting sleeve 7. After loosening the lubrication tube 10, the lubrication tube 10 is reset under the elastic force of the movable spring 22, so that the lubrication hole 14 of the connecting sleeve 7 and the lubrication tube 10 are lubricated. The sliding holes 14 are staggered to prevent the lubricating oil from leaking. The oil filling pipe 15 is threadedly connected to the lubricating pipe 10. When adding oil to the lubricating pipe 10, after taking out the oil filling pipe 15, extend the oil filling hole 16 of the oil filling pipe 15 into the oil barrel, pull the handle 24 and the piston rod 23 outward, and refer to the principle of the syringe to draw the lubricating oil into the oil filling pipe 15 under negative pressure, and squeeze the oil filling spring 26 through the piston plate 25. The air between the piston plate 25 and the oil filling pipe 15 is discharged through the exhaust pipe, and then the oil filling pipe 15 is reinstalled on the lubricating pipe 10. Since the oil filling spring 26 is in a compressed state, the piston plate 25 has the elastic force to move toward the side of the lubricating hole 14, pressurizing the lubricating oil to facilitate oil filling.

[0033] In summary, when the overall equipment is in use or running: when in use, the wheat for flour processing is placed on the screening net 8, and the drive motor 17 is started. The drive motor 17 drives the drive rod 4 to rotate through the cooperation of the pulley 18 and the transmission belt 19, and the eccentric rod 5 is driven to rotate through the drive rod 4. The rotation of the eccentric rod 5 drives the connecting rod 6 to rotate, and the screening net 8 is driven by the connecting rod 6 to reciprocate on the support pulley 20 to screen the wheat and filter out large particles of stones and other impurities. The wheat is recovered through the blanking plate 21.

[0034] During screening, the connecting rod 6 drives the connecting sleeve 7 to rotate on the connecting frame 9. When maintenance is required between the connecting frame 9 and the connecting sleeve 7, the lubrication tube 10 is pressed, and the lubrication tube 10 moves on the movable ring 13 and squeezes the movable spring 22, so that the lubrication hole 14 of the connecting sleeve 7 and the lubrication hole 14 of the lubrication tube 10 are aligned. Then, the lubricating oil flows out through the lubrication tube 10 to between the connecting sleeve 7 and the connecting frame 9 under the pressure in the oil filling tube 15, lubricating the connecting frame 9 and the connecting sleeve 7. After loosening the lubrication tube 10, the lubrication tube 10 is reset under the elastic force of the movable spring 22, so that the lubrication hole 14 of the connecting sleeve 7 and the lubrication hole of the lubrication tube 10 are aligned. 14 are staggered to prevent lubricating oil leakage. The oil filling pipe 15 is threadedly connected to the lubricating pipe 10. When adding oil to the lubricating pipe 10, after taking out the oil filling pipe 15, extend the oil filling hole 16 of the oil filling pipe 15 into the oil barrel, pull the handle 24 and the piston rod 23 outward, and refer to the principle of the syringe to draw the lubricating oil into the oil filling pipe 15 under negative pressure, and squeeze the oil filling spring 26 through the piston plate 25. The air between the piston plate 25 and the oil filling pipe 15 is discharged through the exhaust pipe, and then the oil filling pipe 15 is reinstalled on the lubricating pipe 10. Since the oil filling spring 26 is in a compressed state, the piston plate 25 has the elastic force to move toward the side of the lubricating hole 14, which pressurizes the lubricating oil and facilitates oil filling.
