Description

Technical Field

[0001] This invention relates to the field of flour processing and packaging technology, and in particular to a flour packaging device for food processing. Background Technology

[0002] Flour processing is the process of converting grains such as wheat into flour, mainly including the following steps: removing impurities from the wheat (such as stones, straw, dust, etc.); adding water to the wheat to adjust the moisture content, making the bran less prone to breakage and facilitating subsequent grinding; crushing the wheat using a roller mill to separate the bran, germ, and endosperm. Flour is gradually extracted through multiple grinding and sieving processes; separating materials of different particle sizes using sieves to ensure the fineness and purity of the flour; mixing different grades of flour in proportion according to the target flour's protein content, ash content, and other indicators; and packaging the finished flour into bags for easy storage and transportation.

[0003] The packaging of flour after processing is the process of packaging finished flour according to different specifications, uses and standards. It is directly related to the storage, transportation and sales of the product. It is necessary to ensure that the flour is fully mixed in the storage warehouse to avoid differences between different batches or parts of the flour. The flour to be packaged is subject to final testing, including indicators such as moisture, ash content, protein content, whiteness, and fineness, to ensure that it meets national or enterprise standards. The packaging workshop must be kept clean, dry and well-ventilated, with moderate temperature and humidity to prevent the flour from getting damp or clumping.

[0004] In the existing technology, the flour dispensing process mostly uses pneumatic butterfly valves / ball valves for dispensing. If the bag opening is too large during the dispensing process, a large amount of dust may be emitted, which is unfriendly to the surrounding operators. Therefore, we propose a flour dispensing device for food processing. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a flour dispensing device for food processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A flour dispensing device for food processing includes a base, a conveyor belt at the upper end of the base, dispensing bags stacked on the conveyor belt, a frame above the base, the frame connected to the base by multiple supports, a placement groove penetrating the side wall of the frame, a storage tank placed in the placement groove, the storage tank connected to the placement groove by a connecting device, a driving device fixedly connected to the side wall of the frame at a corresponding position, a crushing device penetrating the side wall of the storage tank, a hydraulic rod fixedly connected to the lower end of the frame, a connecting seat fixedly connected to the extended end of the hydraulic rod, a clamping device penetrating the side wall of the connecting seat, and a discharge device docked at the lower end of the storage tank at a corresponding position.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Reference Figure 1-4A flour dispensing device for food processing includes a base 1, a conveyor belt 2 at the upper end of the base 1 for conveying flour bags to be dispensed, dispensing bags 4 stacked at the conveyor belt 2, a frame 5 above the base 1, the frame 5 and the base 1 are connected by multiple supports 3 to ensure the stability of the overall structure, a placement groove is provided through the side wall of the frame 5, a storage tank 10 is provided in the placement groove, and a feed pipe 11 is provided through the upper end of the storage tank 10.

[0019] The storage tank 10 is connected to the placement tank via a connecting device. The connecting device includes two connecting frames 6 fixedly connected to the inner wall of the placement tank. Both connecting frames 6 are fixedly connected to the side wall of the frame 5 by connecting screws 7. The connecting screws are easy to disassemble and maintain. Support frames 8 are fixedly connected to the lower end of both connecting frames 6. The lower ends of both support frames 8 are attached to the lower end of the storage tank 10 to form a stable support structure.

[0020] Among them, a drive device is fixedly connected to the side wall of the workpiece 5 at the corresponding position. The drive device includes a drive motor 9 fixedly connected to the side wall of the workpiece 5. A connecting column is fixedly connected to the end of the output shaft of the drive motor 9. A connecting groove is provided through the side wall of the connecting column. The connecting column is used to transmit rotational power. A fixing bolt 24 is provided through the connecting groove. The fixing bolt is used to lock the relative position of the connecting column and the storage tank.

[0021] The storage tank 10 is equipped with a crushing device through its side wall. The crushing device includes a sealing pipe 22 that passes through the side wall of the storage tank 10. A rotating rod 20 is rotatably connected to the sealing pipe 22. One end of the rotating rod 20 located inside the storage tank 10 is rotatably connected to the side wall of the storage tank 10 via a rotating seat. The rotating seat ensures that the rotating rod rotates stably inside the tank. A positioning groove is provided through the other end of the rotating rod 20 located outside the storage tank 10. A fixing bolt 24 passes through the positioning groove, which enables the rotating rod and the connecting column to rotate synchronously. A winch 21 is fixedly connected to the side wall of the rotating rod 20 located inside the storage tank 10. The winch is used to crush flour that may clump inside the tank.

[0022] Specifically, a hydraulic rod 12 is fixedly connected to the lower end of the frame 5, and a connecting seat 13 is fixedly connected to the extended end of the hydraulic rod 12. The hydraulic rod is used to adjust the height of the clamping device. A clamping device is provided through the side wall of the connecting seat 13. The clamping device includes two movable slots that are provided through the side wall of the connecting seat 13. A clamping plate 15 is provided in each of the two movable slots. An arc-shaped groove is provided through the opposite side wall between the two clamping plates 15. The arc-shaped groove is used to guide the placement of the flour bag. A rotatable connection is provided to the inner wall of each of the two movable slots. A motor slot is provided through the threaded rod 19 and the connecting seat 13. A vent mesh 18 is provided at the opening of the motor slot to prevent the motor from overheating. A double-headed motor 17 is fixedly connected to the inner wall of the motor slot. The two output ends of the double-headed motor 17 are respectively fixedly connected to the ends of the two threaded rods 19. The threads of the two threaded rods 19 are opposite. The two threaded rods 19 are respectively threaded and connected to the side walls of the two clamping plates 15 located in the moving slot. The double-headed motor drives the two threaded rods to rotate in opposite directions at the same time, so that the clamping plates open and close synchronously.

[0023] It is worth mentioning that a discharge device is installed at the lower end of the storage tank 10 at the corresponding position. The discharge device includes a discharge pipe 16 that is slidably installed at the lower end of the storage tank 10. The discharge pipe can slide to align with the packaging bags at different positions. The position of the discharge pipe 16 corresponds to the position of the two arc-shaped grooves. An airflow butterfly valve body is installed inside the discharge pipe 16. The airflow butterfly valve adjusts the flour discharge speed by controlling the airflow. A transmission plate 14 is fixedly connected to the side wall of the discharge pipe 16. The transmission plate 14 is fixedly connected to the side wall of the connecting seat 13. The transmission plate converts the movement of the clamping device into the sliding of the discharge pipe.

[0024] In this invention, the drive motor 9 drives the connecting column to rotate via its output shaft. The connecting column is locked to the positioning groove of the rotating rod 20 by the fixing bolt 24, thereby driving the winch 21 inside the storage tank 10 to rotate, initially breaking up the flour inside the tank to prevent clumping. At the same time, the hydraulic rod 12 extends and retracts to adjust the vertical position of the connecting seat 13 and the clamping device according to the height of the dispensing bag 4.

[0025] The dual-head motor 17 starts, with its two ends outputting opposite rotations, driving the two threaded rods 19 to rotate synchronously. Since the threads are in opposite directions, the two clamping plates 15 move towards each other along the axial direction of the threaded rods in the moving groove, clamping the packaging bag 4 placed on the conveyor belt 2 through the arc groove. The transmission plate 14 moves with the moving connecting seat 13, driving the discharge pipe 16 to slide, so that its discharge port is precisely aligned with the clamped packaging bag 4.

[0026] After being crushed, the flour in storage tank 10 flows out through the discharge pipe 16 at the lower end. The main body of the airflow butterfly valve in the discharge pipe 16 adjusts its opening according to the preset flow rate or external signal to control the feeding speed and flow rate of the flour, ensuring accurate packaging. The flour enters the packaging bag 4 through the discharge pipe 16.

[0027] Once the current packaging bag 4 is full, the dual-head motor 17 rotates in the opposite direction, causing the two clamping plates 15 to move in the opposite direction along the threaded rod 19, releasing the packaging bag 4. The hydraulic rod 12 can be readjusted in height or kept in its current position. The conveyor belt 2 transports the full packaging bag 4 away and delivers a new empty bag 4 to the clamping position. Throughout the process, all components work together to achieve continuous and stable flour packaging operations.

[0028] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
