Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically a flour processing feeding device. Background Technology

[0002] As a fundamental sector of the food industry, the flour processing sector's production efficiency and product quality are directly constrained by the stability of the feeding process. Traditional flour processing feeding devices generally suffer from problems such as simple structure and limited functionality, leading to issues like uneven feeding, material residue, and equipment blockage during production, which in turn affect finished product quality and production continuity. Specifically, existing technologies face the following technical bottlenecks: Traditional feeding devices mostly rely on gravity-fed natural falling or simple mechanical opening and closing, lacking active control mechanisms. Flour, as a powder material, is prone to fluctuations in feeding amount due to differences in flowability (such as changes in moisture content and particle size), causing instability in parameters of subsequent processing stages (such as grinding and packaging), ultimately affecting the uniformity of flour fineness and batch consistency. For example, on automated production lines, a feeding amount deviation exceeding 5% may lead to excessive moisture content in the finished product or substandard packaging weight. Flour has strong adsorption properties and easily adheres to the inner walls of equipment, forming a residue layer. Traditional equipment often has smooth metal or plastic inner walls, lacking anti-stick design, requiring manual cleaning with the machine stopped—a time-consuming process that can easily leave residue in hard-to-reach areas. Long-term accumulation of residue can breed microorganisms, causing flour mold or insect infestation, seriously threatening food safety. Therefore, those skilled in the art have provided a flour processing and feeding device to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide a flour processing feeding device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A flour processing feeding device, comprising: A feeding hopper is provided with a support frame, a feeding pipe is provided at the upper end of the feeding hopper, a control valve is provided on the feeding pipe, a stirring frame is rotatably connected inside the feeding hopper, a first servo motor is provided on the feeding hopper, and the output end of the first servo motor is connected to the extension end of the stirring frame that passes through the feeding hopper, and a cleaning brush is provided on the stirring frame, and the cleaning brush is in contact with the inner wall of the feeding hopper. The lower end of the feeding hopper is provided with a feeding pipe, the feeding pipe is provided with a uniform feeding component, an infrared sensor is installed on the inner wall of the feeding pipe, a vibration motor is installed on the feeding hopper, and a feeding soft cover is installed on the feeding pipe.

[0005] Preferably, the feeding hopper is equipped with a mounting cover, and the first servo motor is installed inside the mounting cover.

[0006] Preferably, the uniform feeding assembly includes a second servo motor, a rotating rod, and a cross-shaped feeding plate. The cross-shaped feeding plate is rotatably connected inside the feeding tube via the rotating rod. The second servo motor is mounted on the feeding tube, and the output end of the second servo motor is connected to the extension end of the rotating rod that passes through the feeding tube.

[0007] Preferably, the feeding hopper has a locking groove, and one end of the feeding soft cover is fixed in the locking groove by a locking clamp.

[0008] Preferably, the cleaning brush is provided with a connecting plate, and the connecting plate is connected to the stirring frame by mounting bolts.

[0009] Preferably, the feeding hopper is provided with an inspection hole, and an inspection door is installed at the inspection hole by bolts and at the inspection door by fixing bolts.

[0010] Preferably, a controller is installed on the feeding hopper, and the controller is electrically connected to the first servo motor, the second servo motor and the infrared sensor respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention establishes an active and precise feeding control mechanism by incorporating a uniform feeding component and an infrared sensor installed on the inner wall of the feeding tube. This effectively solves the problem of feeding volume fluctuations caused by traditional feeding devices relying on gravity or simple mechanical opening and closing. The infrared sensor monitors the flow state and feeding volume of flour in the feeding tube in real time, feeding the data back to the uniform feeding component. The component can adjust the feeding speed and opening size in a timely manner according to preset parameters, ensuring stable feeding volume and keeping deviations at a low level. This guarantees parameter stability in subsequent processing stages such as grinding and packaging, thereby improving the uniformity of flour fineness and batch consistency. It also reduces problems such as excessive moisture content in finished products or unqualified packaging weight caused by feeding volume deviations, significantly improving production quality and efficiency. Furthermore, this invention features a cleaning brush on the stirring rack inside the feeding hopper, which is in contact with the inner wall of the hopper. Equipped with a vibration motor, this perfectly solves the problem of flour easily adhering to the inner wall and forming a residue layer in traditional feeding devices. As the mixing rack rotates driven by the first servo motor, the cleaning brush simultaneously performs a comprehensive scrubbing of the inner wall of the feeding hopper, effectively removing any adhering flour residue. The vibration generated by the vibrating motor further promotes the removal of stubborn flour residue from the inner wall, preventing residue accumulation. This design eliminates the need for manual cleaning during downtime, saving significant time, improving production continuity, and eliminating blind spots that are easily created by manual cleaning. This prevents long-term residue from breeding microorganisms that can cause flour mold or pests, effectively ensuring food safety. Simultaneously, it reduces the risk of equipment blockage due to residue, extending the equipment's lifespan.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-5 This utility model provides a technical solution: A flour processing feeding device, comprising: The feeding hopper 1 has a support frame 2 installed on it. The upper end of the feeding hopper 1 is provided with a feed pipe 3, and a control valve 4 is installed on the feed pipe 3. A stirring frame 5 is rotatably connected inside the feeding hopper 1. A first servo motor 6 is installed on the feeding hopper 1, and the output end of the first servo motor 6 is connected to the extension end of the stirring frame 5 that passes through the feeding hopper 1. An installation cover 12 is installed on the feeding hopper 1, and the first servo motor 6 is installed inside the installation cover 12. A cleaning brush 7 is provided on the stirring frame 5, and the cleaning brush 7 is in contact with the inner wall of the feeding hopper 1. A connecting plate 18 is provided on the cleaning brush 7, and the connecting plate 18 is connected to the stirring frame 5 by a mounting bolt 19. When adding flour into the feeding hopper 1, the control valve 4 on the feeding pipe 3 is opened, and the flour enters the feeding hopper 1 through the feeding pipe 3. After a certain amount is reached, the control valve 4 is closed. This simple feeding operation will be linked with other systems in subsequent stages. Next comes the mixing and cleaning stage. The first servo motor 6 is started by the controller 22, and its output drives the mixing frame 5 to rotate inside the feeding bucket 1. The first servo motor 6 provides power to the mixing frame 5. The rotation of the mixing frame 5 can mix the flour in the bucket, effectively preventing the flour from clumping. This solves the problem of flour clumping and affecting the smoothness of feeding caused by the lack of a mixing structure in traditional devices. On the other hand, the cleaning brush 7, which is fixed on the mixing frame 5 by the connecting plate 18 and the mounting bolt 19, will rotate synchronously with the mixing frame 5 and come into close contact with the inner wall of the feeding bucket 1. It uses friction to wipe and clean the inner wall. At the same time, the vibration motor 10 can be started as needed. The vibration waves generated by the motor are transmitted to the bucket wall, causing stubborn flour residue to fall off. This forms a dual cleaning mechanism of "active wiping + vibration assistance". Compared to traditional methods that require manual cleaning during shutdown, this cleaning system not only saves a significant amount of manual cleaning time and improves production continuity, but also completely eliminates blind spots in manual cleaning, preventing long-term residue from breeding microorganisms that could cause flour mold or pests, thus effectively ensuring food safety. At the same time, it reduces the risk of equipment blockage caused by residue clumping, extending the overall service life of the equipment. Furthermore, the structure of the cleaning brush 7 connected by mounting bolts 19 facilitates quick replacement of the cleaning brush 7 after wear, reducing maintenance costs and further demonstrating the advantages of convenient equipment maintenance.

[0015] The lower end of the feeding hopper 1 is provided with a feeding pipe 8, and a uniform feeding component is provided on the feeding pipe 8. The uniform feeding component includes a second servo motor 13, a rotating rod 14 and a cross feeding plate 15. The cross feeding plate 15 is rotatably connected to the feeding pipe 8 through the rotating rod 14. The second servo motor 13 is installed on the feeding pipe 8, and the output end of the second servo motor 13 is connected to the extension end of the rotating rod 14 that passes through the feeding pipe 8. An infrared sensor 9 is installed on the inner wall of the feeding pipe 8. A vibration motor 10 is installed on the feeding hopper 1, and a feeding soft cover 11 is installed on the feeding pipe 8.

[0016] Furthermore, the feeding hopper 1 is provided with a locking groove 16, and one end of the feeding soft cover 11 is fixed in the locking groove 16 by a locking clamp 17. The feeding hopper 1 is provided with an inspection hole 20, and an inspection door is installed at the inspection hole 20 by bolts 19 and an inspection door 21 is installed at the inspection hole 20 by fixing bolts.

[0017] When using this flour processing feeding device, the staff needs to check the condition of each component to ensure that the inspection door 21 is firmly installed at the inspection hole 20 by bolt fixing bolt 19, and that one end of the feeding soft cover 11 is stably fixed in the clamping groove 16 of the feeding bucket 1 by clamping clamp 17. This structurally avoids the problem of loosening and leakage. The cooperative design of clamping clamp 17 and clamping groove 16 reduces the material waste caused by flour spillage, demonstrating the advantages of the device in terms of practicality and economy.

[0018] Upon entering the uniform feeding stage, the second servo motor 13 is activated. Its output drives the rotating rod 14 and the cross-shaped feeding plate 15 on the rotating rod 14 to rotate within the feeding tube 8. The rotation of the cross-shaped feeding plate 15 periodically opens and closes the feeding channel, achieving preliminary quantitative feeding. From the perspective of working principle, this stage forms a complete "monitoring-decision-execution" automated feeding closed loop: the infrared sensor 9, as the "sensing unit," collects the flow data of flour in the feeding tube 8 in real time through infrared detection technology, converts the analog signal into an electrical signal, and transmits it to the controller 22; the controller 22, as the "decision unit," compares the preset flow parameters with the actual monitoring data, calculates the adjustment command through the built-in control algorithm, and outputs it to the second servo motor 13; the second servo motor 13, as the "execution unit," adjusts the speed according to the command, changes the rotation frequency of the cross-shaped feeding plate 15, and thus precisely controls the feeding speed and feeding amount. Compared to traditional feeding methods that rely on gravity or simple mechanical opening and closing and lack active control mechanisms, this closed-loop system can control the feeding deviation to an extremely low range. This effectively avoids problems such as uneven grinding fineness and unqualified packaging weight caused by feeding fluctuations, ensuring batch consistency in flour production. It perfectly meets the needs of automated production lines for efficient and stable production, significantly improving product quality stability. Simultaneously, the protective design of the mounting cover 12 for the first servo motor 6 prevents flour dust from entering the motor and affecting its normal operation, improving motor stability and lifespan, and further enhancing the overall reliability of the device.

[0019] When inspecting the inside of the feeding hopper 1, remove the bolt fixing bolt 19, and then remove the inspection door 21 to inspect the inside of the feeding hopper 1.

[0020] In the above embodiment, a controller 22 is installed on the feeding hopper 1, and the controller 22 is electrically connected to the first servo motor 6, the second servo motor 13 and the infrared sensor 9 respectively.

[0021] It should be noted that the specific models and specifications of the controller 22, the first servo motor 6, the second servo motor 13, and the infrared sensor 9 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
