[0003] Patent application CN215043880U, published on 2021-12-07, entitled "A Quantitative Filling Device for Bagged Products," discloses a quantitative filling device for bagged products, comprising a base, bottom plate, guide rod, side plate, fixing rod, slide groove, first motor, connecting rod, limiting block, feed hopper, limiting ring, filter screen, discharge pipe, slider, limiting plate, limiting groove, mounting plate, discharge port, storage bucket, partition, quantitative tray, first sensor, second sensor, first space, second space, measuring orifice, and discharge hopper. This utility model features high quantitative accuracy, simple structure, and practical function. It solves the problem that most existing quantitative feeding devices for powdered foods use electronic scales for quantitative weighing and packaging, which are often complex in structure, require high precision from the electronic scales, are costly, and lack universal applicability.

[0004] In the aforementioned patents or existing technologies, the feeding devices generally lack effective dust suppression and protection structures during the material feeding process. When feeding powdery raw materials such as peanut protein powder, the impact of falling materials and airflow disturbances easily cause powder to fly and disperse, polluting the working environment, affecting on-site working conditions, and leading to unnecessary loss and waste of raw materials. Furthermore, the scattered powder settles on and around the equipment, requiring frequent cleaning, which increases maintenance costs and the workload of operators.

[0005] Therefore, it is necessary to invent a peanut protein powder feeding device that prevents powder from flying to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a peanut protein powder feeding device that prevents powder from flying. By setting up an adjustable guide plate, a dust baffle plate group and a negative pressure dust collection mechanism, the device achieves coordinated control of dust suppression and material flow during the feeding process, thereby solving the problems of powder flying, working environment pollution, raw material waste and increased cleaning burden caused by the lack of effective protection in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a peanut protein powder feeding device to prevent powder from flying, comprising a support platform, a feeding pipe installed at an incline on the support platform, a feeding control component installed inside the feeding pipe, a feeding hopper installed through the high opening of the feeding pipe, a cover plate rotatably installed above the feeding hopper, and an anti-splash component installed at the low opening of the feeding pipe. The anti-splash assembly includes a dust baffle plate 1, which is symmetrically arranged at the low opening of the feeding pipe. A dust baffle plate 2 is arranged between the two sets of dust baffle plates 1, and a highly elastic diaphragm is installed between the edge of the dust baffle plate 2 and the edge of the two sets of dust baffle plates 1.

[0008] In a preferred embodiment of the present invention, the feeding control component includes a baffle plate, which is rotatably connected to the inner wall of the feeding pipe. A rotating frame is sleeved on the feeding pipe, and the inner wall of the rotating frame is axially connected to the baffle plate at the rotatable connection point.

[0009] As a preferred embodiment of the present invention, a limiting frame is installed on one side above the support platform, and multiple sets of limiting grooves are sequentially opened in the limiting frame. A connecting shaft is connected through the limiting frame, and the connecting shaft is fixedly connected to the outside of the rotating frame.

[0010] As a preferred embodiment of the present invention, a handle is rotatably connected to the connecting shaft, and the handle is engaged with the limiting groove in the limiting frame. A limiting cylinder is installed on one side above the support platform, and the inner wall of the limiting cylinder is rotatably connected to the connecting shaft.

[0011] As a preferred embodiment of the present invention, a torsion spring is sleeved on the connecting shaft, and one end of the torsion spring is fixedly connected to the connecting shaft, while the other end is fixedly connected to the inner wall of the limiting cylinder.

[0012] As a preferred embodiment of the present invention, the anti-splash assembly further includes a guide plate, which is rotatably connected below the low opening of the feeding pipe and is located between two sets of dust baffles.

[0013] In a preferred embodiment of the present invention, a connecting rod is rotatably connected to the lower part of one of the two sets of dust baffles, and one end of the connecting rod is rotatably connected to the surface of the feeding pipe, and the dust baffle is connected to the surface of the feeding pipe.

[0014] As a preferred embodiment of the present invention, the outer sides of the two sets of dust baffles and the upper part of the rotating frame are rotatably connected by connecting arms, and the outer side of the guide plate is also rotatably connected by connecting arms to the lower part of the rotating frame.

[0015] In a preferred embodiment of the present invention, suction hoods are installed on the inner sides of both sets of dust baffles and the second set of dust baffles. As a preferred embodiment of the present invention, a vacuum cleaner is installed above the support platform, and the vacuum cleaner is connected to each set of suction hoods by a flexible hose.

[0016] Compared with the prior art, the technical effects and advantages provided by the present invention in the above technical solution are as follows: 1. By rotating and adjusting dust baffle one and dust baffle two, the system can automatically adapt to changes in the angle of the guide plate. This allows the suction hood to maintain a reasonable distance from the material falling onto the guide plate while effectively collecting peanut protein powder dust that diffuses outward. The guide plate can also automatically adjust its tilt angle according to the actual amount of material fed, significantly reducing the impact force of falling material, suppressing powder flying at the source, greatly reducing dust dispersion, and effectively ensuring a clean processing environment and the health and safety of operators. 2. By turning the handle, the rotating frame is driven to rotate, which in turn drives the baffle to rotate. The feeding amount can be precisely adjusted by controlling the rotation amplitude. At the same time, with the help of the transmission action of the connecting arm, the rotating frame can synchronously drive the guide plate, dust baffle one, and dust baffle two to work together, realizing linkage adjustment according to the feeding amount, ensuring dynamic matching between the dust suppression structure and the feeding state, and improving the coordination and operating efficiency of the overall system.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] The present invention provides a peanut protein powder feeding device for preventing powder from flying, as shown in Figures 1-8, including a support platform 001, a feeding pipe 101 installed obliquely above the support platform 001, a feeding control component 002 installed inside the feeding pipe 101, a feeding hopper 102 installed through the high opening of the feeding pipe 101, a cover plate 103 rotatably installed above the feeding hopper 102, and an anti-splash component 003 installed at the low opening of the feeding pipe 101; The feeding hopper 102 can hold peanut protein powder, and the cover plate 103 ensures a sealed environment during the feeding process when closed. The protein powder is conveyed downwards to the processing device along the feeding pipe 101. The feeding amount is regulated by the feeding control component 002, and the anti-splash component 003 effectively blocks any flying powder during the feeding process.

[0022] The anti-splash assembly 003 includes a dust baffle 301, which is symmetrically arranged on the feeding pipe. At the low-level opening 101, a second dust baffle 303 is provided between the two sets of dust baffles 301, and the second dust baffle... A highly elastic diaphragm is installed between the edge of 303 and the edges of the two sets of dust baffles - 301.

[0023] Dust baffles 301 in the anti-splash assembly 003 are symmetrically arranged on both sides of the low outlet of the feed pipe 101, with a second dust baffle 303 located between them. The edges of each baffle are connected by a highly elastic diaphragm, forming a deformable sealing structure. This structure maintains its overall protective performance during rotation, effectively suppressing... Powder escaped.

[0024] Furthermore, in the above structure, the feeding control component 002 includes a baffle 201, which is rotatably connected to the inner wall of the feeding pipe 101. A rotating frame 202 is sleeved on the feeding pipe 101, and the inner wall of the rotating frame 202 is axially connected to the baffle 201 at the rotatable connection point.

[0025] The feeding control component 002 rotates the frame 202 to drive the baffle 201 to rotate, thereby opening and closing the feeding pipe 101 channel and controlling the material flow.

[0026] Furthermore, in the above structure, a limiting frame 203 is installed on one side above the support platform 001, and multiple sets of limiting grooves are sequentially opened in the limiting frame 203. A connecting shaft 204 is connected through the limiting frame 203, and the connecting shaft 204 is fixedly connected to the outside of the rotating frame 202.

[0027] The rotating frame 202 is fixedly connected to the connecting shaft 204, and the rotation angle can be segmented and positioned by the multiple limiting grooves set in the limiting frame 203.

[0028] Furthermore, in the above structure, a handle 205 is rotatably connected to the connecting shaft 204, and the handle 205 is engaged with the limiting groove in the limiting frame 203. A limiting cylinder 206 is installed on one side above the support platform 001, and the inner wall of the limiting cylinder 206 is rotatably connected to the connecting shaft 204.

[0029] The handle 205 is rotatably connected to the connecting shaft 204 and can be snapped into different limiting slots for easy operation and fixation.

[0030] Furthermore, in the above structure, a torsion spring 207 is sleeved on the connecting shaft 204, and one end of the torsion spring 207 is fixedly connected to the connecting shaft 204, while the other end is fixedly connected to the inner wall of the limiting cylinder 206.

[0031] A torsion spring 207 is sleeved on the connecting shaft 204, with its two ends connected to the inner walls of the connecting shaft 204 and the limiting cylinder 206, respectively, to provide a reset torque for the rotating frame 202 and ensure that the handle 205 is stably locked in the limiting groove.

[0032] Furthermore, in the above structure, the anti-splash assembly 003 also includes a guide plate 304, which is rotatably connected below the low opening of the feeding pipe 101, and the guide plate 304 is located between the two sets of dust baffles 301.

[0033] The guide plate 304 is rotatably installed below the outlet of the feeding pipe 101, located between the two dust baffles 301. By adjusting its tilt angle, the material falling trajectory and impact force can be changed, thereby reducing powder flying.

[0034] Furthermore, in the above structure, a connecting rod 302 is rotatably connected below the two sets of dust baffles 301, and one end of the connecting rod 302 is rotatably connected to the surface of the feeding pipe 101, and the dust baffle 303 is connected to... A connecting rod 302 is also rotatably connected between the surfaces of the feeding pipe 101.

[0035] The dust baffle 1 301 and dust baffle 2 303 are rotatably connected to the outer wall of the feeding pipe 101 via the connecting rod 302, so that the spacing can be adjusted to meet the protection requirements under different feeding conditions.

[0036] Furthermore, in the above structure, connecting arms 305 are rotatably connected between the outer sides of the two sets of dust baffles 301 and the upper part of the rotating frame 202, and connecting arms 305 are also rotatably connected between the outer side of the guide plate 304 and the lower part of the rotating frame 202.

[0037] The rotating frame 202 is connected to dust baffle 1 301, dust baffle 2 303, and guide plate 304 via connecting arm 305, thereby realizing the linkage between feeding control and anti-splash mechanism. When the opening of rotating frame 202 increases and the feeding amount increases, the angle between guide plate 304 and feeding pipe 101 decreases, and the material falls more smoothly; at the same time, the opening of dust baffle assembly expands, maintaining an effective shielding range while avoiding interference with guide plate 304, thus improving the overall protection effect.

[0038] Furthermore, in the above structure, suction hoods 306 are installed on the inner sides of the two sets of dust baffles 301 and the two sets of dust baffles 303, and a vacuum cleaner 307 is installed on the support platform 001. The vacuum cleaner 307 is connected to each set of suction hoods 306 by a flexible hose.

[0039] The suction hoods 306, located inside each dust baffle, are connected to the vacuum cleaner 307 via flexible hoses. This allows for negative pressure collection during the initial stages of powder dispersion, preventing further diffusion. The dynamic adjustment function of the dust baffles maintains an appropriate distance between the suction hoods 306 and the powder flow, ensuring efficient recovery while avoiding direct contact with the material and guaranteeing continuous and stable system operation.

[0040] As shown in Figure 1-8, before feeding, the peanut protein powder raw material is first loaded into the feeding hopper 102, and the cover plate 103 is closed to form a sealed space to prevent dust from escaping. When feeding is required, the operator turns the handle 205 to disengage it from the limiting groove of the limiting frame 203. Continuing to rotate the handle 205, the rotating frame 202 is rotated as a whole through the connecting shaft 204, which in turn causes the baffle 201 installed in the feeding pipe 101 to rotate, opening the feeding channel. At this time, the peanut protein powder is conveyed downwards along the feeding pipe 101 under the action of gravity.

[0041] At the same time, the rotating frame 202 drives the symmetrically arranged dust baffle 301 and the middle dust baffle 303 to unfold synchronously through the connecting arm 305, forming an adjustable enclosure structure. The guide plate 304 below also rotates with the connecting arm 305, adjusting its angle with the end of the feeding pipe 101.

[0042] This linkage mechanism achieves coordinated control of material feeding and splash prevention: the rotation amplitude of the rotating frame 202 directly adjusts the opening of the baffle 201, controlling the amount of material fed; simultaneously, the angle of the guide plate 304 changes accordingly, affecting the material feeding. The falling protein powder acts as a buffer and guide, reducing the impact and flying at the source; the expansion range of dust baffle 1 301 and dust baffle 2 303 is matched with the amount of material fed, which expands the physical blocking range while ensuring that the inner suction hood 306 maintains a reasonable distance from the main powder flow.

[0043] Ultimately, while efficiently feeding materials, a small amount of airborne protein powder is effectively captured by the suction hood 306 and collected by the vacuum cleaner 307 through the hose, thereby achieving a closed-loop, low-dust clean production operation.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
