Description

Technical Field

[0001] This invention relates to an oat flake air separation device and its process, belonging to the field of sorting equipment. Background Technology

[0002] In oatmeal processing, the air separation and impurity removal step after slicing is crucial for ensuring the quality of the final product. This step differs fundamentally from the air separation of whole oats earlier. Whole oats are compact and smooth, so air separation focuses on removing whole stones and moldy oats. Sliced ​​oats, however, are brittle and rough, requiring precise removal of discolored and moldy slices while preventing breakage and sticking. Current technologies often use traditional electromagnetic vibrators for air separation and conveying of sliced ​​oats. These vibrators drive the conveyor trough to vibrate, moving and separating the sliced ​​oats to provide clear individual material imaging for visual identification of discolored and moldy slices, thus ensuring air separation accuracy.

[0003] The sliced ​​oatmeal is brittle. If the output power is too low and the vibration intensity is insufficient, it will not be able to overcome the large friction between the slices, causing the oatmeal to be unable to move forward normally, or even to accumulate and get stuck. If the output power is increased to ensure the movement of materials, the violent vibration will directly cause a large amount of oatmeal to break, producing too much debris. This not only reduces the product yield, but the debris will also cover the discolored and moldy slices, affecting the air separation accuracy. At the same time, the debris is easy to get stuck in the gaps of the vibration mechanism, causing blockage. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an oat flake air separation device and its process to solve the above problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an oat flake air separation device and its process, comprising: a frame; a feeding device mounted on the frame for receiving and spreading oat flakes; a guide trough connected to the outlet of the feeding device for slowly conveying the oat flakes; a sorting section located below the guide trough, equipped with a built-in camera for visually identifying impurities and a pneumatic sorting mechanism; and a material separating trough located below the sorting section, including a waste trough. The feeding device includes a discharge device, which comprises a material trough and a base. The material trough and the base are rotatably coupled. The base is equipped with a driver that adjusts the discharge angle of the material trough by pushing a toothed column. The material trough includes a vibrating plate and a pusher. The pusher is equipped with a vibrating jet nozzle and a pushing jet nozzle, respectively providing vertical pulse airflow to drive vibration and horizontal airflow to push the oat flakes.

[0006] Preferably, the feeding device further includes a collection bin and multiple auxiliary bins, and the cereal is collected by the collection bin and then diverted and pushed to the discharge device by the auxiliary bins.

[0007] Preferably, the material trough includes an outer trough, the inner wall of which is provided with a guide slope that covers the edge of the vibrating plate, and also includes a first guide plate located at the outlet of the outer trough.

[0008] Preferably, the vibrating plate further includes a feeding plate and multiple second guide plates, wherein the feeding plate and the second guide plates are arranged in a stepped staggered manner along the conveying direction; a through groove is opened in the middle of the second guide plate, and the outlet of the pusher is located at the through groove.

[0009] Preferably, the feeding plate and the second guide plate are provided with positioners and limiting slots on both sides. The feeding plate is connected to a drive rod, which adjusts the displacement of the feeding plate through a threaded connection. The limiting slot includes a movable plate with a connecting groove inside. The movable plate is connected to the feeding plate through the connecting groove. A positioning plate with sliding fit is also provided adjacent to the movable plate. A drive rod is provided in the middle of the positioning plate. The movable plate and the positioning plate are in sliding fit.

[0010] Preferably, the thickness of the second guide plate is greater than the thickness of the feeding plate, one side of the second guide plate is fixed to the inner groove of the positioner, and the other side is movably engaged with the connecting groove of the limiting groove block.

[0011] Preferably, the vibrating plate adopts a plastic film structure; the base is equipped with a detection camera facing the material discharge position of the trough.

[0012] Preferably, the detection signal from the detection camera dynamically adjusts the pulse frequency of the pusher to achieve adaptive feeding control.

[0013] Preferably, the actuator includes a solenoid valve, a cavity, a connecting pipe, and a flow divider column. The connecting pipe is connected to an external high-pressure air pump, and the flow divider column integrates the vibration jet nozzle and the driving jet nozzle.

[0014] Preferably, the gap between the propulsion nozzle and the second guide plate is opposite.

[0015] As a preferred sorting process, the following is adopted:

[0016] S1: The feeding device is connected to an external feeding pipe, which feeds the raw material into the inside of the feeding device from the top.

[0017] S2: The equipment starts up, the detection camera and the camera inside the sorting section are in working condition, and at the same time the pusher of the material trough starts to work;

[0018] S3: The detection camera located at the bottom of the outer tank detects the cereal passing through the first guide plate. When the amount passing through is too small, the driver works to control the movement of the push tooth column, which increases the inclination angle of the trough.

[0019] S4: The solenoid valve controls the vibrating jet nozzle and pushes the jet nozzle outlet to release air, so that the feeding plate can vibrate and shake the oatmeal to the second guide plate and then drop it to the guide groove, where it is spread out flat.

[0020] S5: The vibration amplitude can be controlled by controlling the displacement of the limit slot block by controlling the drive rod to adjust the tension of the feeding plate;

[0021] S6: After passing through the sorting section, the internal camera identifies impurities and sorts them into the distribution tank.

[0022] This invention discloses an oat flake air-separation device and its process, which has the following advantages: A feeding plate and multiple second guide plates are arranged in a stepped, staggered pattern along the material conveying direction, ensuring a smooth transition of the oat flakes while gradually thinning them. A through-slot is formed in the center of each second guide plate, and the push nozzle of the actuator is precisely located within this slot. The nozzle position is precisely aligned with the through-slot, ensuring that the airflow can fully act on the oat flakes, avoiding airflow waste or misalignment. The outlet direction of the push nozzle is horizontally pointed towards the material conveying direction. When the airflow exits from this nozzle, it directly acts on the oat flakes located at the end of the next step, such as the feeding plate, providing a horizontal thrust that allows them to smoothly "slide" to the next step, such as the second guide plate, thus solving the problems of fragmentation caused by excessive vibration and difficulty in spreading the oat flakes.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0040] The existing sliced ​​oatmeal has a brittle texture. Traditional electromagnetic vibrators have insufficient output power and vibration intensity to overcome the large friction between the slices, causing the oatmeal to be unable to move forward normally and even to accumulate and get stuck. If the output power is increased to ensure material movement, the violent vibration will directly cause a large amount of oatmeal to break, producing too much debris. This not only reduces the product yield, but the debris can also obscure discolored or moldy slices, affecting the accuracy of air separation. At the same time, debris can easily get stuck in the gaps of the vibration mechanism, causing blockage. Therefore, in order to solve the above problems, this paper proposes the following technical solution:

[0041] Please see Figures 1 to 7 This invention provides an oat flake air separation device and its process technology solution: its structure includes: a frame 2, a feeding device 1 installed on the frame 2 for receiving and spreading oat flakes; a guide groove 3 connected to the outlet of the feeding device 1 for slowly conveying oat flakes; a sorting section 4 located below the guide groove 3, with a built-in camera for visually identifying impurities and a pneumatic sorting mechanism; and a material sorting trough 5 located below the sorting section 4, including a waste trough; wherein, the feeding device 1 includes a discharge device 13, the discharge device 13 includes a material trough 31 and a base 32, the material trough 31 and the base 32 are rotatably coupled, the base 32 is provided with a driver 34 to adjust the discharge elevation angle of the material trough 31 by pushing a toothed column 35; the material trough 31 includes a vibrating plate 312 and a pusher 313, the pusher 313 is configured with a vibrating jet nozzle 135 and a pushing jet nozzle 136, which respectively provide vertical pulse airflow to drive vibration and horizontal airflow to push oat flakes.

[0042] Figure 1 As shown, the automatic oat cleaning device provided by the present invention mainly includes a frame 2, a feeding device 1, a guide trough 3, a sorting section 4, and a distributing trough 5. Each component is assembled and connected to the frame 2 according to a preset configuration. The frame 2 serves as the installation foundation for the entire device, providing stable support for each component and ensuring the structural stability of the device during operation.

[0043] The feeding device 1 is used to receive the oat flakes transported from the outside and spread them evenly into a thin layer to prepare for subsequent precise sorting. After spreading, the oat flakes slide slowly and orderly down the guide trough 3 to the detection station of the sorting section 4. The guide trough 3 controls the downward movement of the oat flakes to prevent them from accumulating and getting stuck, while also controlling the downward speed to ensure that the sorting section 4 has sufficient time for detection and identification.

[0044] The sorting unit 4 has a built-in high-speed camera that performs real-time visual recognition of the falling cereal, accurately distinguishing pure cereal from cereal of different colors. Through the pneumatic nozzles arranged at the front and back inside, i.e. the pneumatic sorting mechanism, the identified impurities are accurately blown into the waste trough of the material distribution tank 5 according to the visual recognition results, while the pure cereal falls into the finished product tank along a preset trajectory, achieving efficient separation of impurities and pure cereal.

[0045] The feeding device 1 includes a collection bin 11, multiple auxiliary bins 12, and a discharge device 13. The cereal first enters the collection bin 11 for temporary storage. The bottom of the collection bin 11 is equipped with a distribution channel, which can evenly distribute the temporarily stored cereal to each auxiliary bin 12. Each auxiliary bin 12 synchronously feeds cereal to the discharge device 13, avoiding uneven spreading caused by single feeding. Finally, the cereal that has been regulated by the auxiliary bins 12 is uniformly conveyed to the discharge device 13.

[0046] like Figure 3 As shown, the feeder 13 includes a feed trough 31 and a base 32. The feed trough 31 is rotatably connected to the base 32 via a rotating shaft, allowing the angle of the feed trough 31 relative to the base 32 to be adjustable. A driver 34 is installed on one side of the base 32. In this embodiment, a stepper motor and a gearbox are used to accurately control the distance of its displacement. The output shaft gear drives the external teeth of the gear column 35 to move, which in turn drives the feed trough 31 to move. The outlet elevation angle of the feed trough 31 is precisely adjusted through gear transmission. The overall outflow speed of the oatmeal is controlled by the change of the gravitational component. It can be flexibly adjusted according to actual production needs to adapt to the conveying requirements of oatmeal with different humidity and particle size.

[0047] The base 32 is also equipped with a detection camera 33 at the front end, which is used to monitor the continuity and uniformity of the cereal curtain falling from the outlet of the feed trough 31 in real time. The monitoring range of the detection camera 33 completely covers the outlet, and the monitoring data is transmitted to the control system in real time to provide data support for subsequent adaptive adjustment.

[0048] The core pneumatic vibratory conveying mechanism of this invention is located inside the material trough 31. This mechanism is the key to achieving precise spreading of the cereal flakes. Figure 2 and Figure 3 As shown, the feed trough 31 has an outer trough 311, the inner wall of which is designed with a guide slope 314. This slope can reduce the gap at the edge of the vibrating plate 312, effectively preventing small particles of material from getting stuck, and avoiding the impact of material jamming on the continuity of conveying and vibration effect. The outer trough 311 is also provided with a first guide plate 315, which is located at the outlet of the outer trough 311 and is set at an angle. It can perform a final guiding and straightening of the oatmeal about to flow out of the feed trough 31, further ensuring the uniformity of the oatmeal curtain and ensuring the detection accuracy of the subsequent sorting section 4. The vibrating plate 312 is made of a smooth plastic film such as PET or food-grade polyethylene, which is laid flat at the bottom of the outer trough 311. This material not only has a smooth surface, which can reduce the friction between the oatmeal and the vibrating plate 312, but also has a certain degree of flexibility to adapt to high-frequency micro-amplitude vibration, while meeting food-grade requirements to avoid contaminating the oatmeal.

[0049] The vibration of the vibrating plate 312 and the material pushing are accomplished by the pusher 313. The pusher 313 includes a solenoid valve 131, a cavity 132, a connecting pipe 133, and a diverter column 134. The connecting pipe 133 is connected to an external high-pressure air pump to provide a stable high-pressure air source for the pusher 313. The solenoid valve 131 is controlled by the control system and can achieve high-speed switching, so that pulsed airflow is generated in the cavity 132. The pulse frequency can be flexibly adjusted according to actual needs. The diverter column 134 integrates two nozzles with different functions: a vibration nozzle 135 and a pushing nozzle 136, which are used to realize the vibration of the vibrating plate 312 and the directional pushing of the cereal, respectively.

[0050] like Figure 7 The outlet of the vibrating nozzle 135 is vertically upward or slightly inclined, directly facing the lower surface of the vibrating plate 312. When the pulsed airflow is ejected from the vibrating nozzle 135, it impacts the vibrating plate 312 vertically, causing it to produce high-frequency, micro-amplitude up-and-down vibrations. The vibration frequency is consistent with the frequency of the pulsed airflow and can be precisely adjusted by the solenoid valve 131. This vibration is sufficient to break up the adhesion and accumulation between the cereal flakes, making them loose and easy to flow, while being very gentle. This avoids the mechanical impact caused by traditional mechanical vibration, effectively reducing cereal flake damage and protecting cereal flake quality.

[0051] To achieve directional conveying of the oatmeal, the trough is equipped with a feeding plate 124 and multiple second guide plates 125, which are arranged in a stepped, staggered manner along the material conveying direction to ensure a smooth transition and gradual thinning of the oatmeal. A through-slot 126 is opened in the middle of the second guide plate 125, and the push nozzle 136 of the pusher 313 is precisely located in this through-slot 126. The nozzle position is precisely aligned with the through-slot 126 to ensure that the airflow can fully act on the oatmeal, avoiding airflow waste or misalignment. The outlet direction of the push nozzle 136 is horizontally pointed in the material conveying direction. When the airflow exits from this nozzle, it directly acts on the oatmeal located at the end of the next step, such as the feeding plate 124, giving it a horizontal thrust, allowing it to smoothly "slide" to the next step, such as the second guide plate 125. This combined structure allows the oatmeal to be continuously redistributed and thinned during the conveying process, ultimately forming a uniform thin layer at the outlet, meeting the requirements of subsequent sorting and inspection.

[0052] The feeding plate 124 and the second guide plate 125 are installed and adjusted on both sides by the positioner 121 and the limiting groove block 123. The limiting groove block 123 is provided with a movable plate 231, and the movable plate 231 is provided with a connecting groove 232. The end of the feeding plate 124 is embedded in the connecting groove 232 to achieve a fixed connection with the movable plate 231. The second guide plate 125 slides with the connecting groove 232 and is fixedly connected with the positioner 121 for easy adjustment.

[0053] A slidingly fitted positioning plate 233 is also provided adjacent to the movable plate 231. The positioning plate 233 is fixedly connected to the outer groove 311. A drive rod 122 is provided in the middle of the positioning plate 233. The drive rod 122 is threadedly connected to the connecting groove 232. Rotating the drive rod 122 can drive the movable plate 231 to move, thereby adjusting the position of the feeding plate 124, realizing the tensioning or relaxation of the feeding plate 124, and thus changing its vibration characteristics to adapt to the conveying of cereal in different states. The thickness of the second guide plate 125 is greater than that of the feeding plate 124, and it has high rigidity to ensure that it does not deform under the action of airflow. It only serves as a guide surface to provide stable support and guidance for the cereal. One side of the second guide plate 125 is fixed to the connection structure of the locator 121, and the other side is movably fitted to the groove of the locator 121. The angle of the second guide plate 125 can be finely adjusted according to the actual paving requirements to further optimize the paving effect.

[0054] The process of oat flake air separation device:

[0055] S1: The feeding device 1 is connected to an external feeding pipe, which feeds the raw material into the inside of the feeding device 1 from the top.

[0056] S2: The equipment is started, and the detection camera 33 and the camera inside the sorting section 4 are in working condition. At the same time, the pusher 313 of the material trough 31 starts to work.

[0057] S3: The detection camera 33 located at the bottom of the outer trough 311 detects the cereal passing through the first guide plate 315. When the amount passing through is too small, the driver 34 works to control the movement of the push tooth column 35, so that the inclination angle of the trough 31 increases.

[0058] S4: Solenoid valve 131 controls the vibration nozzle 135 and pushes the nozzle 136 to output air, so that the feeding plate 124 can vibrate and shake the oat flakes to the second guide plate 125 and then drop them to the guide groove 3, where they are spread out flat through the guide groove 3.

[0059] S5: The vibration amplitude can be controlled by controlling the displacement of the limit block 123 via the drive rod 122 to control the tension adjustment of the feeding plate 124;

[0060] S6: After passing through the sorting section 4, the internal camera identifies impurities and sorts them into the waste bin of the material distribution bin 5. Normal oatmeal slides smoothly into the discharge bin through the guide trough 3.

[0061] When the system is working, the detection camera 33 continuously monitors the material discharge status, and the monitoring data is transmitted to the control system in real time. The control system dynamically adjusts the pulse frequency of the pusher 313 according to the detection signal of the detection camera 33 to achieve adaptive feeding control.

[0062] If the oatmeal flow rate is found to be too fast or the layer thickness is uneven, the control system will adjust the control signal of the solenoid valve 131 of the pusher 313. For example, it may reduce the pulse frequency of the vibrating nozzle 135 to reduce the fluidization intensity of the material and slow down the oatmeal flow rate, or adjust the air pressure of the push nozzle 136 to change the pushing force and prevent oatmeal accumulation. Conversely, if the material flow rate is too slow or even jams, the pulse frequency of the vibrating nozzle 135 and the air pressure of the push nozzle 136 will be increased to enhance the fluidization intensity and pushing force of the material and speed up the oatmeal conveying speed. This closed-loop feedback control keeps the conveying process in an optimal state at all times. At the same time, the driver 34 can also fine-tune the outlet elevation angle of the trough 31 according to the instructions of the control system, and further optimize the conveying effect in conjunction with the adjustment of the pusher 313.

[0063] The pneumatic sorting mechanism of the sorting section 4 consists of front and rear air jets. After the high-speed camera captures impurities, the control system accurately determines the position and trajectory of the impurities and controls the corresponding air jets to spray air. The front and rear air jets can form a directional airflow to ensure that the impurities are accurately blown into the waste tank of the sorting tank 5, preventing impurities from mixing into the finished product tank, while not affecting the falling trajectory of the pure oatmeal, further improving the sorting accuracy.

[0064] The above description only outlines the basic principles and preferred embodiments of the present invention. Those skilled in the art can make many changes and modifications based on the above description, and these changes and modifications should fall within the protection scope of the present invention.

[0065] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
