Description

Technical Field

[0001] This invention relates to the field of biscuit processing equipment technology, and more specifically, to an online airflow uniformity and diversion device. Background Technology

[0002] With the development of the industry and the increasing demands of consumers for food safety and quality, the performance and hygiene of biscuit sorting devices have become particularly important. Most biscuit sorting devices use air blowing to achieve the sorting operation. Although this traditional method can achieve the sorting purpose to a certain extent, it has caused a series of serious drawbacks.

[0003] During the blowing process, crumbs from the biscuit surface will inevitably be blown everywhere. Once these crumbs spread, they will not only contaminate the overall environment of the production workshop, but also enter critical parts such as air nozzles, solenoid valves, and gaps in the slide rails. When crumbs accumulate in these places, they are very likely to breed bacteria, which seriously violates food hygiene requirements and poses a potential risk to consumers' health.

[0004] Because the airflow has a limited area of ​​contact, and the biscuits themselves have a high center of gravity and are thin, they are prone to tipping over, standing up, or even getting stuck in the chute when impacted by airflow. This not only causes uneven distribution of biscuits, affecting the continuity of the production process, but also requires frequent manual intervention for adjustment, increasing labor costs and reducing overall production efficiency.

[0005] In summary, existing biscuit diversion devices have significant shortcomings in terms of hygiene, reliability, and diversion efficiency, necessitating a novel device that can effectively address these issues. This device must not only meet food hygiene standards but also possess highly efficient and stable diversion performance to meet the stringent requirements of modern food production for both hygiene and high-efficiency manufacturing, ensuring the smooth operation of the biscuit production process and the steady improvement of product quality.

[0020] Furthermore, cable fittings are fixedly installed on the side of the mounting side plate, and protective side plates are fixedly installed on both sides of the guide plate.

[0021] By adopting the above technical solution, the protective side plate can shield and protect both sides of the guide plate.

The second negative pressure fan is connected to the first adsorption pipe and the second negative pressure fan on the upper side, respectively.

[0023] By adopting the above technical solution, the first and second adsorption tubes can be in a suction state by the second negative pressure fan, which facilitates the separation of biscuits.

[0024] Furthermore, a separation air pump is fixedly installed at the upper end of the upper frame, and the guide plate is provided with stepped plates on both sides of the isolation component.

[0032] like Figure 1 - Figure 8 As shown, the embodiment of the present invention provides: including a mounting base 4, a guide plate 5 fixedly mounted on the upper end of the mounting base 4, a plurality of exhaust pipes 21 fixedly mounted at equal intervals on the side of the mounting base 4, a plurality of dividing pieces 8 fixedly mounted at equal intervals on the upper side of the guide plate 5, a plurality of isolation pieces 501 staggered on the side of the dividing pieces 8, a first adsorption pipe 22 opened on the upper side of one side of the dividing piece 8, a first adsorption pipe 22 opened on the upper side of the dividing piece 8, a second adsorption pipe 24 opened in the middle of the upper side of the dividing piece 8, and a plurality of stepped grooves 23 opened on the side of the guide plate 5 located on the second adsorption pipe 24. The guide plate 5 is provided with an exhaust trough 28 on the lower side of the stepped groove 23. The guide plate 5 is rotatably provided with a rotating cover 31 between the two exhaust troughs 28. The lower end of the rotating cover 31 is provided with a rotating base 30. The lower side of the rotating base 30 is fixedly installed with a drive motor 29. Mounting base 4 has mounting frames 3 on both sides, mounting side plates 1 are fixedly mounted on the upper end of the mounting frames 3 on both sides, a detection plate 2 is rotatably mounted on the side of the mounting side plate 1, an upper frame 9 is fixedly mounted between the two mounting side plates 1, and a main control screen 7 is fixedly mounted on the front side of the upper frame 9. A flipping component 10 is fixedly installed on the side of the detection plate 2. An arc-shaped fixing groove is opened on the side of the detection plate 2. Several adjustment grooves 14 are equally spaced on the side of the flipping component 10. Several infrared detectors 17 are fixedly installed on the flipping component 10 at the position of the adjustment grooves 14. A connecting cable 18 is provided at the upper end of the infrared detector 17. The infrared detector 17 is electrically connected to the upper frame 9. The tilt angle of the detection plate 2 can be adjusted according to different types of biscuits so that the infrared detector 17 can be aligned with the biscuits passing below for easy detection. Mounting base 4 and mounting frame 3 are fixedly connected by mounting bracket 12. The side of mounting frame 3 is provided with arc groove. The operator can fix the mounting frame 3 in the middle of the device with bolts. The operator can adjust the tilt position of mounting frame 3 according to the angle of other devices to facilitate subsequent material feeding. A negative pressure plate 15 is fixedly installed on the side of the guide plate 5 near the first adsorption tube 22. A first negative pressure fan 16 is fixedly installed on the lower side of the guide plate 5 below the negative pressure plate 15. The lower side of the negative pressure plate 15 is fixedly connected to the exhaust end of the first negative pressure fan 16. When the biscuit passes the position of the negative pressure plate 15, the small airflow formed by the negative pressure plate 15 will make the biscuit stick to the position of the negative pressure plate 15, reduce shaking, and prevent it from being blown out by the airflow later. The upper ends of the exhaust ducts 28 are connected to the stepped ducts 23 respectively, the lower ends of the pairs of exhaust ducts 28 are connected to the side of the rotating cover 31, and the pairs of stepped ducts 23 are connected to the corresponding exhaust ducts 28, so that the adjacent stepped ducts 23 can be under negative pressure simultaneously, which facilitates the matching of the diversion pipe 6. The rotating cover 31 has an exhaust trough 34 on its side, and a rotating component 35 is fixedly installed at the lower end of the rotating cover 31. The upper middle part of the rotating base 30 has a ventilation trough 32, and the lower middle part of the rotating cover 31 has an annular groove corresponding to the ventilation trough 32. The upper end of the rotating base 30 has a rotating groove 33 corresponding to the rotating component 35. An exhaust pipe 3001 is fixedly installed on the side of the rotating base 30. The ventilation trough 32 is connected to the exhaust pipe 3001. A third negative pressure fan 27 is fixedly installed on the guide plate 5 at the air outlet end of the exhaust pipe 3001. The exhaust pipe 3001 can be connected to the middle part of the upper rotating cover 31 through the ventilation trough 32. When the rotating cover 31 is rotating, the exhaust pipe 3001 can always draw air from the internal space of the ventilation trough 32, so that the ventilation trough 32 and the middle part of the rotating cover 31 are always in a negative pressure state. A circular through slot is provided in the middle of the rotating base 30. The output end of the drive motor 29 passes through the circular through slot in the middle of the rotating base 30 and is fixedly connected to the rotating cover 31. The drive motor 29 can drive the upper rotating cover 31 to rotate, so that the exhaust duct 34 can be regularly aligned with the stepped duct 23 on the side. Cable fittings 11 are fixedly installed on the side of the mounting side plate 1, and protective side plates 13 are fixedly installed on both sides of the guide plate 5. The protective side plates 13 can shield and protect both sides of the guide plate 5. A sealing frame 19 is fixedly installed on the upper side of the inner cavity of the mounting base 4. A second negative pressure fan 26 is installed inside the sealing frame 19. The second negative pressure fan 26 is connected to the first adsorption tube 22 and the second negative pressure fan 26 on the upper side respectively. The second negative pressure fan 26 can make the first adsorption tube 22 and the second adsorption tube 24 in the exhaust state respectively, which facilitates the biscuit diversion. A separation air pump 20 is fixedly installed at the upper end of the upper frame 9. The guide plate 5 is located on both sides of the isolation component 501 and has stepped plates 25. The separation air pump 20 can divert sterile gas from the position of the diversion pipe 6 to the biscuits. The stepped plates 25 make it convenient for the diversion pipe 6 to use a small amount of gas to evenly distribute the biscuits.

[0033] Working principle of the invention: The device is supported by the mounting base 4, and the guide plate 5 at the upper end is used to carry and guide the movement of the biscuits. The mounting base 4 and the mounting frame 3 are fixedly connected by the mounting bracket 12. The arc groove on the side of the mounting frame 3 makes it easy for the operator to fix it in the middle of the device with bolts and adjust the tilt position according to the angle of other equipment to facilitate the subsequent feeding of biscuits. The biscuits move from the negative pressure plate 15 to the isolation member 501 under the influence of gravity and inertia. The detection plate 2, which is rotatably mounted on the side of the mounting side plate 1, can be angled by the side-fixed flipping member 10. The operator can align the infrared detector 17 with the biscuit passing below according to the different types of biscuits on the production line. It is electrically connected to the upper frame 9 through the connecting cable 18 to detect the biscuits and provide data support for subsequent diversion operations. The negative pressure plate 15 is connected to the first negative pressure fan 16 on the lower side, which can generate continuous negative pressure. When the biscuit passes through the negative pressure plate 15... When in position, the lower side of the biscuit will be in contact with the negative pressure plate 15 to reduce shaking during movement and prevent it from being blown out by subsequent airflow, ensuring the stability of the biscuit during transmission. The infrared detector 17 will detect the biscuits passing by on the lower side. Odd-numbered biscuits will slide from the side near the diversion tube 6 to the side of the isolation member 501 under the action of gravity. When even-numbered biscuits pass through the position of the diversion tube 6, the separation air pump 20 will pump out sterile airflow from the diversion tube 6, which can give a lateral force to the passing biscuit, causing the biscuit to move to the side away from the diversion tube 6, thereby separating the biscuits. The second negative pressure fan 26 inside the upper sealing frame 19 of the inner cavity of the mounting base 4 puts the first adsorption tube 22 and the second adsorption tube 24 into a suction state. When an even number of biscuits pass through the negative pressure plate 15, the second negative pressure fan 26 on the lower side of the first adsorption tube 22 and the stepped groove 23 is started. At this time, the first adsorption tube 22 and the second adsorption tube 24 will generate a horizontal negative pressure. When the airflow is ejected from the diversion pipe 6, the biscuits can move quickly. The airflow on both sides can effectively reduce the excessive unidirectional airflow of the traditional diversion pipe 6, which causes the biscuits to become unstable during movement and fall over, stand up, or even get stuck at the slide opening. The stepped plates 25 on both sides of the isolation piece 501 on the guide plate 5 assist the diversion pipe 6 in using a small amount of gas to achieve uniform diversion of biscuits. Meanwhile, the exhaust duct 28 connected to the lower end of the stepped groove 23 on the guide plate 5 is connected to the side of the rotating cover 31. The exhaust pipe 3001 on the side of the rotating base 30 at the lower end of the rotating cover 31 is connected to the middle of the rotating cover 31 through the ventilation groove 32. Under the action of the third negative pressure fan 27, the ventilation groove 32 and the middle of the rotating cover 31 are always kept in a negative pressure state. The drive motor 29 drives the rotating cover 31 to rotate, so that the exhaust duct 34 is regularly aligned with the stepped groove 23 on the side, realizing the intermittent negative pressure of the stepped groove 23. When the biscuit moves to the bottom of the diversion pipe 6, the biscuit is simultaneously pushed by the diversion pipe 6 and the second adsorption pipe 24. Since the diversion pipe 6 does not generate an upward airflow, the biscuit is easy to tip over. If a negative pressure area is generated below, it will easily affect the movement of the biscuit. However, the rotating cover 31 can quickly apply alternating negative pressure to the exhaust duct 28, so that the biscuit remains stable and does not affect the horizontal movement of the biscuit, reducing the jumping of the biscuit caused by the airflow.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
