[0011] Preferably, a dispersion mechanism is provided on one side of the opening and closing plate, and the dispersion mechanism includes a telescopic rod, one end of the telescopic rod is hinged to one side of the opening and closing plate, and the other end of the telescopic rod is hinged to the right side of the inner wall of the fixed box, the inner wall of the telescopic rod is provided with a built-in spring, the outer wall of the telescopic rod is fixedly connected to a connecting sleeve, and the outer wall of the connecting sleeve is fixedly connected to a toggle rod.

[0012] Preferably, a thin one-way valve and a thick one-way valve are provided on the outer wall of the telescopic rod, the thin one-way valve is communicated with the inside of the telescopic rod, and the thick one-way valve is communicated with the inside of the telescopic rod.

[0013] The present invention provides a raw material feeding device for producing kudzu powder shortbread, which belongs to the technical field of food industrial processing and intelligent manufacturing equipment, and has the following beneficial effects: 1. Automatic quantitative feeding control: Through the linkage and toggle design of the baffle and the opening and closing plate, the precise quantitative delivery of raw materials is achieved. The mechanism innovatively adopts the intermittent material dropping mode, which has the following improvements compared to the traditional manual dumping method: it eliminates the uneven accumulation of materials caused by manual dumping, effectively prevents small raw materials from rolling off both sides of the conveyor belt, supports continuous feeding of large-capacity storage bins, achieves improved work efficiency, and ensures the continuous and stable operation of the conveyor line, reducing the frequency of more manual intervention.

[0014] 2. Intelligent adjustment mechanism based on speed feedback: When the conveyor belt speed increases, the rotation inertia drives the opening and closing plates to increase the opening and closing angles, forming an extended blanking channel; Overspeed protection mode: When the speed exceeds the threshold value Vmax, the magnetic attraction of the first and second magnetic plates will lock the opening and closing plates in the fully open position, ensuring full-capacity delivery under high-speed conditions; 3. Anti-sticking vibration system: The arc block-pull rope-rotating plate transmission chain is used to achieve mechanical vibration with adjustable amplitude. The inclination angle of the rotating plate is automatically adjusted, and the separation efficiency of the sticking raw materials is improved.

[0015] 4. When the opening and closing plate opens the feeding channel, the telescopic rod will change its angle to lift, squeeze and move the raw materials accumulated in the fixed box, which can push the raw material particles that are adhered to each other, scatter them, and evenly fall onto the conveyor belt through the gaps between each connecting sleeve, ensuring that the materials on the conveyor belt are evenly scattered.

[0016] 5. When the telescopic rod retracts, the fine one-way valve has a small diameter. During the retraction process, the internal air can only be discharged slowly through the fine one-way valve, forming a controllable damping effect, thereby delaying the reset action and giving the raw materials a certain amount of time to fall, avoiding the situation where the opening and closing plate is closed as soon as it is pushed open, and ensuring stable raw material feeding.

[0017] 6. The rotation of the telescopic rod will drive the connecting sleeve and the toggle rod to rotate synchronously, so that the toggle rod can quickly move the raw material particles inside the fixed box, so that the raw material particles that adhere to each other due to moisture and friction can be fully dispersed, ensuring the stability of the feeding speed and avoiding the uneven feeding phenomenon caused by squeezing and jamming.

DETAILED DESCRIPTION

[0020] Example 1: Please refer to Figures 1-4 The present invention provides a technical solution: a raw material feeding device for producing kudzu powder shortbread, comprising a support frame 2, a conveyor 1 is fixedly connected to the top of the support frame 2, a conveyor belt 5 is arranged inside the conveyor 1, and a feeding mechanism 3 is arranged on the top of the conveyor belt 5; The feeding mechanism 3 comprises: The baffle 301 is an arc-shaped plate structure. A fixed box 303 is fixedly connected to the top of the conveyor 1. A containing box 302 is fixedly connected to the top of the fixed box 303. A feeding trough 304 is provided on the top of the fixed box 303. The baffle 301 is used to block raw material particles. A feeding trough 304 is a circular trough, which is opened on the top of the fixed box 303. An opening and closing plate 309 is provided inside the fixed box 303. A rotating plate 313 is provided inside the fixed box 303. The rotating plate 313 is used to hold raw material particles; When in use, the raw material particles are put into the containing box 302, and then the conveyor 1 is started to control the conveyor belt 5 to transmit and transport upward. The raw material particles in the containing box 302 will fall on the conveyor belt 5, and then be transported upward to a high place with the conveyor belt 5, and then fall down from one end of the high place of the conveyor belt 5, completing the transportation of the raw material particles from a low place to a high place; Example 2: Please refer to Figures 1-10, based on the first embodiment, the present invention provides a technical solution: in the field of raw material processing and production, the uniform feeding of raw materials is a key link to ensure the stable operation of the production line and product quality. The traditional feeding method is usually that workers pour a large amount of raw materials onto the conveyor belt at one time. However, this method has many disadvantages: On the one hand, since the amount of raw materials poured at one time is difficult to accurately control, the raw materials are unevenly distributed on the conveyor belt, and it is easy to have a situation where there is too much raw material accumulation in some areas and too little in some areas. This not only affects the normal transmission of raw materials on the conveyor belt, but also easily causes the raw materials to roll off from both sides of the conveyor belt, resulting in raw material waste and pollution of the production environment; On the other hand, when pouring a large amount of raw materials at one time, for small raw material particles, when they are transported on the inclined conveyor belt, they are very easy to roll down due to sliding, and it is impossible to ensure that the small raw material particles are evenly and stably transported on the inclined conveyor belt, thus affecting the smooth progress of subsequent production processes.

[0021] In addition, the raw materials may absorb moisture during storage, resulting in some raw materials becoming more adhesive. In the traditional feeding process, these adhesive raw materials are difficult to be fed smoothly, easily block the feeding port, and affect the feeding efficiency; Moreover, most of the existing feeding devices cannot automatically adjust the feeding amount according to the transmission speed of the conveyor belt. When the transmission speed of the conveyor belt is relatively fast, it is easy to have a situation of insufficient feeding, resulting in the interruption of raw material supply in the production line; when the transmission speed of the conveyor belt is relatively slow, there may be a problem of excessive feeding, causing raw material accumulation and waste. This not only increases the workload of workers, but also reduces production efficiency and product quality. Therefore, a partition plate 305 is fixedly connected to the top inner wall of the fixed box 303, an arc plate 306 is fixedly connected to the bottom of the partition plate 305, a rotating sleeve 307 is rotatably connected to the inner wall of the arc plate 306, a rotating shaft 308 is rotatably connected to the inner wall of the rotating sleeve 307, both ends of the rotating shaft 308 are fixedly connected to the inner wall of the fixed box 303, and the bottom of the rotating sleeve 307 is fixedly connected to the top of the opening and closing plate 309.

[0022] An arc-shaped block 310 is fixedly connected to the bottom of the opening and closing plate 309, and a first magnetic plate 311 is fixedly connected to one side of the opening and closing plate 309. A second magnetic plate 315 is fixedly connected to the inner wall of the fixed box 303.

[0023] The second magnetic plate 315 and the first magnetic plate 311 are magnetic, and the magnetic properties of the mutually approaching sides of the second magnetic plate 315 and the first magnetic plate 311 are opposite poles attracting each other.

[0024] A hinge rod 314 is rotatably connected to the inner wall of the fixed box 303. One end of the hinge rod 314 is fixedly connected to the inner wall of the fixed box 303 through a torsion spring, and one side of the hinge rod 314 is fixedly connected to one side of the rotating plate 313.

[0025] A pull rope 312 is fixedly connected to the bottom of the arc block 310, and the other end of the pull rope 312 is fixedly connected to the bottom of the rotating plate 313; When the conveyor belt 5 is transporting, it will drive the baffle plate 301 on the outer wall of the conveyor belt 5 to move synchronously, and the baffle plate 301 will move the opening and closing plate 309 inside the fixed box 303. When the opening and closing plate 309 is moved, it is lifted by the rotation of the rotating sleeve 307, and the gap between the opening and closing plate 309 and the first magnetic plate 311 is opened, and the particles that fall into the fixed box 303 through the feeding chute 304 will be separated by the isolation plate 305, so that the raw material particles can only enter the right side of the isolation plate 305 and fall, and are contained by the opening and closing plate 309 and the rotating plate 313. Therefore, when the opening and closing plate 309 is pushed open as the conveyor belt 5 and the baffle plate 301 move, the gap formed between the opening and closing plate 309 and the rotating plate 313 allows the solid particles to enter the fixed box 303 through the feeding chute 304. A large amount of raw material particles accumulated in the fixed box 303 fall onto the conveyor belt 5 with the gap therein and are blocked by the baffle 301 on the right side, forming a pile between the two baffles 301. At the same time, the opening and closing plate 309 is closed again and closed with the rotating plate 313, so that when each baffle 301 and the opening and closing plate 309 are moved, a certain amount of raw material is automatically put onto the conveyor belt 5 for uniform loading, thus avoiding the problem that the staff pours the raw materials onto the conveyor belt 5 at one time, resulting in uneven distribution of the raw materials and easy rolling down from both sides of the conveyor belt 5. In addition, a large amount of raw materials can be dumped at one time, and stable, uniform and uninterrupted loading can be achieved through the loading mechanism 3, thus saving a lot of time for the staff and improving the transmission efficiency. When the smaller raw material particles fall, they will fall between the two baffles 301 on the conveyor belt 5 and be blocked by the baffle 301 on the right side. As the conveyor belt 5 is transported upward, a large number of raw material particles can be prevented from sliding and rolling down under the transmission of the inclined conveyor belt 5, thereby ensuring that the small raw material particles can be transported evenly and stably on the inclined conveyor belt 5. When the opening and closing plate 309 is pushed to open and close by the baffle 301, the arc block 310 will pull the pull rope 312, and the pull rope 312 will be pulled to the rotating plate 313, and the rotating plate 313 will drive the hinge rod 314 to rotate downward, so that the rotating plate 313 changes from a tilted shape to a slope shape to improve the efficiency of raw material feeding, and when the opening and closing plate 309 is moved, the pull rope 312 will pull the rotating plate 313 to vibrate, so that the raw material particles accumulated on the rotating plate 313 can be shaken away by the vibration, and the raw materials squeezed and stuck together due to friction inside are avoided, so as to avoid the problem of moisture in the raw materials during the feeding process, which makes it difficult to feed the raw materials due to adhesion. When the moving speed of the conveyor belt 5 is relatively fast, the speed at which the baffle 301 toggles the opening and closing plate 309 also increases synchronously, thereby increasing the impact force of the baffle 301 on the opening and closing plate 309. When the opening and closing plate 309 is originally toggled by the baffle 301, it will only fall back to its original position after rotating a certain angle and disengaging from the baffle 301. However, when the speed at which the baffle 301 toggles the opening and closing plate 309 is relatively fast and the impact force is relatively large, the opening and closing plate 309 will increase the opening and closing angle due to the rotational inertia of the rapid impact, so that when transporting raw materials quickly, a larger gap between the opening and closing plate 309 and the rotating plate 313 can be opened, realizing the automatic opening of a larger feeding channel when the conveyor belt 5 is running at a relatively fast speed, so as to ensure that enough raw materials can be transported between each baffle 301, realizing the automatic and adaptive adjustment of the feeding amount according to the transport speed, ensuring the stability and transport efficiency of the transport work, and eliminating the need for manual control, reducing the work burden; If the transmission speed of the baffle 301 increases to exceed the threshold value, when impacting the opening and closing plate 309, the opening and closing plate 309 will be rotated by the impact force and its own inertia to approach the second magnetic plate 315, and through the magnetic attraction between the opposite poles of the first magnetic plate 311 and the second magnetic plate 315, the opening and closing plate 309 will be firmly fixed on the second magnetic plate 315, so that when the transmission speed of the conveyor belt 5 is greater than the threshold value, the opening and closing plate 309 can be continuously opened, allowing the raw materials to fall continuously, so as to ensure that when the transmission speed is very fast, the raw materials can also fully fill the space between each baffle 301, ensuring that the feeding amount of the raw materials can be synchronized with the increase in the transport speed; Embodiment Three: Please refer to Figures 1-13 , based on Embodiment One and Embodiment Two, the present invention provides a technical solution: When the traditional feeding device is feeding, the baffle that often blocks the material often quickly resets after being opened, resulting in the raw materials being blocked when falling, and it is impossible to ensure the stability and uniformity of the feeding of the raw materials. Moreover, due to the lack of a device for evenly toggling the raw materials, the distribution of the raw materials on the conveyor belt is uneven, which brings difficulties to the subsequent material collection work and reduces the production efficiency.

[0026] In addition, when the existing feeding device faces raw materials with different humidities and frictions, the feeding speed is unstable and is prone to the phenomenon of being sometimes fast and sometimes slow. This will not only affect the overall rhythm of the production line, but may also cause equipment failures and increase production costs. Therefore, a dispersion mechanism 4 is provided on one side of the opening and closing plate 309. The dispersion mechanism 4 includes a telescopic rod 401. One end of the telescopic rod 401 is hinged to one side of the opening and closing plate 309, the other end of the telescopic rod 401 is hinged to the right side inner wall of the fixed box 303, an internal spring is provided inside the telescopic rod 401, a connecting sleeve 404 is fixedly connected to the outer wall of the telescopic rod 401, and a toggling rod 405 is fixedly connected to the outer wall of the connecting sleeve 404.

[0027] A thin one-way valve 402 and a thick one-way valve 403 are provided on the outer wall of the telescopic rod 401. The thin one-way valve 402 is connected to the inside of the telescopic rod 401, and the thick one-way valve 403 is connected to the inside of the telescopic rod 401. When the opening and closing plate 309 is rotated and lifted by the baffle 301, the hinged telescopic rod 401 will be pulled to extend, and the telescopic rod 401 is provided with a built-in spring, so when the telescopic rod 401 is stretched, the built-in spring will be deformed, and then the opening and closing plate 309 will be given a force to return to its original position, so that the opening and closing plate 309 can be returned to its original position in time every time it is moved by the baffle 301; When the opening and closing plate 309 opens the feeding channel, the telescopic rod 401 is pulled synchronously, and the telescopic rod 401 changes its angle to lift, squeeze and move the raw materials accumulated in the fixed box 303, so that the raw material particles adhering to each other can be pushed to scatter and evenly fall onto the conveyor belt 5 through the gaps between each connecting sleeve 404, ensuring that the materials on the conveyor belt 5 are scattered evenly, which is convenient for the uniform and stable collection of the materials on the conveyor belt 5 at the rear; When the opening and closing plate 309 is pushed open by the baffle 301, the opening and closing plate 309 will not be quickly pulled back to its original position by the built-in spring in the telescopic rod 401. When the telescopic rod 401 retracts, the air inside can only be discharged outward through the one-way ventilated fine one-way valve 402. The fine one-way valve 402 has a small diameter, so the exhaust is slow. The retraction speed of the telescopic rod 401 is limited, giving the raw materials a certain amount of time to fall, avoiding the situation where the opening and closing plate 309 is closed just after being pushed open, thereby ensuring stable raw material feeding. The multiple sections of the inner wall of the telescopic rod 401 are connected by a thread type, and the thread type of the inner wall of the telescopic rod 401 has a large lead angle. Therefore, when the telescopic rod 401 is pulled and stretched, it can rotate a certain number of circles. Since the thread lead angle of the inner thread of the telescopic rod 401 is large, the pulling friction is small, and the stretching speed is not affected. At this time, the rotation of the telescopic rod 401 will drive the connecting sleeve 404 and the toggle rod 405 to rotate synchronously, so that the toggle rod 405 can quickly toggle the raw material particles inside the fixed box 303, so that the raw material particles attached to each other due to moisture and friction are fully dispersed, thereby ensuring the stability of the feeding speed and avoiding the uneven feeding phenomenon of sometimes fast and sometimes slow due to squeezing; When the telescopic rod 401 is squeezed and stretched, the air inside the telescopic rod 401 will only be sucked out through the one-way ventilated thick one-way valve 403. Since the thick one-way valve 403 has a large diameter, the air extraction is not hindered, so the telescopic rod 401 is not hindered from stretching but its retraction is limited.

[0028] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention should cover within the protection scope of the present invention any equivalent substitution or change made according to the technical solution and inventive concept of the present invention.
