Technical Field
[0001] This utility model relates to the field of flour processing technology, specifically to an automatic flour feeding and metering device. Background Technology
[0002] Flour is a powdery substance made from milled wheat. Based on its protein content, flour can be classified into high-gluten flour, medium-gluten flour, low-gluten flour, and gluten-free flour. Flour processing is the process of converting wheat into edible flour through a series of steps, mainly including cleaning, grinding, and sieving.
[0003] Patent CN223073263U discloses an automatic flour feeding and metering device, which includes a frame, a conveying cylinder, a sieve hopper, and a metering barrel. The conveying cylinder is installed on the frame, the sieve hopper is located at the top of the inlet end of the conveying cylinder, and the metering barrel is located at the bottom of the outlet end of the conveying cylinder. This device ensures the quality of the supplied flour and sets a metering mechanism at the tail end of the flour supply and conveying mechanism, so that the flour can better match the equipment in the next process and improve the convenience of flour processing.
[0004] However, this device has a limitation: after the flour is discharged into the conveying cylinder and transported to the metering bin through the sieve hopper, the servo motor must be turned off to stop the flour conveying for a long time. Furthermore, the flour in the metering bin must be discharged before the servo motor can drive the auger to continue conveying the flour, which affects the flour conveying and metering efficiency. To address this issue, an automatic flour feeding and metering device is proposed to solve the problem that the existing metering device is difficult to continuously weigh and convey flour, thus affecting the metering efficiency.

[0015] (III) Beneficial Effects
[0016] 1. This automatic flour feeding and metering device adds flour to the metering trough through a feeding mechanism. After weighing to the required weight using a weighing plate and pressure sensor, the device, in conjunction with a synchronous controller, activates an electric push rod. This, along with a connecting plate, moves a movable seat to connect with the metering trough and the right-side outlet to discharge the flour. Simultaneously, the required amount of flour is added to the left-side metering trough. After this, the movable seat resets, and the left-side metering trough connects with the left-side outlet to discharge the flour. This process repeats automatically, solving the problem of some metering devices being unable to continuously weigh and deliver flour, thus affecting metering efficiency.
[0017] 2. This automatic flour feeding and metering device continuously adds flour to the feed trough in the upper hopper during the process of conveying and bagging flour via a conveyor belt. Then, under the action of the sprocket and chain, the rotating shaft drives the scraper to rotate, thereby stably scraping the flour into the feeding box. At the same time, the servo motor drives the auger to stably guide the flour into the metering trough, ensuring a smooth flour metering and discharge process. Attached Figure Description

[0025] Furthermore, the output shaft of the motor 4 is fixedly connected to the right drive shaft 3. When the moving seat 9 is in the initial position, the left metering tank 10 and the left discharge port 11 are interconnected, and the moving seat 9 and the conveying box 1 are slidably connected.
[0026] Furthermore, the output end of the electric push rod 14 is fixedly connected to the connecting plate 15, and the pressure sensor 13, the electric push rod 14, and the synchronous controller 18 are electrically connected.
[0027] Furthermore, the feeding mechanism 8 includes a feeding box 801 fixedly connected to the top of the vertical plate 7. A feeding hopper 802 is provided on one side of the feeding box 801. The feeding hopper 802 communicates with the inner cavity of the feeding box 801. An auger 803 is provided in the inner cavity of the feeding box 801. The surface of the auger 803 is roughened. When the moving seat 9 is in the initial position, the metering groove 10 on the right side communicates with the inner cavity of the feeding box 801.
[0028] Furthermore, a servo motor 804 is fixedly connected to the top of the feeding box 801. The output shaft of the servo motor 804 passes through the feeding box 801 and is connected to the auger 803. A rotating shaft 805 is provided in the inner cavity of the feeding hopper 802. A sprocket 806 is fixedly connected to one end of the outer ring of the rotating shaft 805 and the left drive shaft 3. The sprocket 806 is connected by a chain 809.
[0029] Furthermore, the inner cavity of the feeding hopper 802 is provided with a guide groove 808. The cavity wall of the guide groove 808 is smoothed. A scraper 807 is fixedly connected to the outer ring of the rotating shaft 805. The scraper 807 is located at the junction of the feeding box 801 and the feeding hopper 802. After the flour is continuously weighed and discharged through the two metering grooves 10 in the moving seat 9, the flour will pass through the discharge outlet 11 into the conveying box 1 and be conveyed to the right by the conveyor belt 2 to enter the discharge hopper 6, where it can be bagged. During the process of conveying and bagging the flour by the conveyor belt 2, flour can be continuously added to the guide groove 808 in the feeding hopper 802. Then, under the action of the sprocket 806 and the chain 809, the rotating shaft 805 drives the scraper 807 to rotate, thereby stably scraping the flour into the feeding box 801.

The top of the movable seat 9 is sealed by the first sealing plate 16 to prevent external dust and impurities from entering the metering tank 10 and affecting the quality of the flour. The outlet 11 is blocked by the second sealing plate 17 to prevent dust from overflowing when the flour is discharged into the conveying box 1, which would affect the health of personnel and the environment.
[0031] Working principle: When using this automatic flour feeding and metering device, flour is added to the metering tank 10 through the feeding mechanism 8. After being weighed to the required weight by the weighing plate 12 and pressure sensor 13, the electric push rod 14 is opened in conjunction with the synchronous controller 18. The connecting plate 15 drives the moving seat 9 to move to the metering tank 10 and the right outlet 11 to discharge the flour. At the same time, the left metering tank 10 continues to add the required amount of flour. Then the moving seat 9 returns to its original position, and the left metering tank 10 and the left outlet 11 are connected to discharge the flour. This process is repeated automatically, which solves the problem that some metering devices have difficulty continuously weighing and conveying flour, thus affecting the metering efficiency. After the flour is continuously weighed and discharged by the two metering tanks 10 in the moving seat 9, the flour will pass through the outlet 11 and enter the conveyor box 1. It will then be conveyed to the right by the conveyor belt 2 to enter the discharge hopper, where it can be bagged.
