Description

Technical Field

[0001] This utility model belongs to the field of vacuum feeding machine technology, specifically referring to a vacuum feeding machine with uniform material output. Background Technology

[0002] In many industrial sectors, such as chemical, food, pharmaceutical, and plastics industries, it is often necessary to transport powdery or granular materials. These materials need to be transferred from one location to another for subsequent processing. Vacuum feeders can accurately transport materials from raw material storage areas or other source locations to production equipment or processing containers, ensuring the continuity of the production process.

[0003] Traditional vacuum feeders often suffer from uneven material discharge, leading to an imbalance in the raw material ratio in subsequent processing equipment and resulting in unstable final product quality. Moreover, the feeding process of traditional vacuum feeders varies greatly due to the different flowability of various materials. Especially when handling materials with poor flowability, feeding blockages frequently occur, seriously interfering with the normal operation of the entire production process and affecting production efficiency and product quality stability. Utility Model Content

[0004] To address the issues of uneven material discharge and material flowability differences in traditional vacuum feeders, this invention provides a vacuum feeder with uniform material discharge.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A vacuum feeder with uniform discharge includes an L-shaped support column, a square vacuum feed cylinder, and a suction pipe with a switch valve. The L-shaped support column is arranged in four sets, with each pair corresponding to the front and rear sides of the vacuum feed cylinder. A vacuum pump connected to the outside is installed at the top of the vacuum feed cylinder. The suction end of the vacuum pump passes through the top of the vacuum feed cylinder and is connected to the inside of the vacuum feed cylinder. The end of the suction pipe is connected to the side of the vacuum feed cylinder. A trapezoidal discharge port is connected to the bottom of the vacuum feed cylinder. A rectangular solenoid valve outlet is connected to the bottom of the trapezoidal discharge port. A cylindrical, horizontally arranged distribution cylinder is connected to the bottom of the solenoid valve outlet. Support columns are evenly arranged at the bottom of the distribution cylinder. A discharge component is installed inside the distribution cylinder.

[0006] The discharge assembly includes a spiral blade that is rotatably disposed inside the discharge cylinder. The bottom end of the solenoid valve outlet is connected to one side of the discharge cylinder, and the discharge port that runs vertically through the other side of the discharge cylinder is connected to the bottom of the discharge cylinder.

[0007] As a preferred embodiment of the present invention, the discharge assembly further includes a drive motor fixed to the side of the distributing cylinder, the output end of which rotates through the side of the distributing cylinder and is connected to the end of the spiral blade.

[0008] As a preferred technical solution of this utility model, a material conveying assembly is provided inside the vacuum feeding cylinder. The material conveying assembly includes a rotary motor fixed to the side of the vacuum feeding cylinder and a material distributing fan blade that is laterally rotated inside the vacuum feeding cylinder. The output end of the rotary motor rotates through the vacuum feeding cylinder and is connected to the end of the material distributing fan blade.

[0009] As a preferred embodiment of this utility model, an inclined filter plate with a handle is inserted into the vacuum feeding cylinder, and the end of the suction pipe is located between the inclined filter plate and the distributing fan blades.

[0010] As a preferred embodiment of this utility model, the edge of the spiral blade is closely fitted to the inner wall of the dispensing cylinder.

[0011] As a preferred embodiment of this utility model, the end of the suction pipe away from the vacuum feeding cylinder is tapered.

[0012] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure:

[0013] 1. Through the setting of the discharge component, the drive motor drives the spiral blades to rotate at a uniform speed, so that the material moves steadily along the spiral trajectory in the distribution cylinder, ensuring the uniformity and stability of the discharge, effectively solving the problems of uneven material flow rate and jamming that may occur during the discharge of traditional feeders, and greatly improving the accuracy and efficiency of material conveying.

[0014] 2. Through the setting of the material conveying component, the rotary motor drives the material distribution fan blades to rotate, which can quickly disperse the material that has accumulated on the material distribution fan blades after entering the vacuum feeding cylinder from a localized concentrated state, avoiding the accumulation and blockage of material at the bottom of the cylinder. Especially for materials with different flow rates, the rotation of the material distribution fan blades can achieve uniform distribution and smooth flow, laying a good foundation for subsequent material discharge operations.

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4As shown, this utility model provides a vacuum feeder with uniform material output, including an L-shaped support column 1, a square vacuum feed cylinder 2, and a suction pipe 3 with a switching valve. Four sets of L-shaped support columns 1 are correspondingly arranged on the front and rear sides of the vacuum feed cylinder 2, providing stable support for the entire device. A vacuum pump 4 connected to the outside is installed at the top of the vacuum feed cylinder 2. The suction end of the vacuum pump 4 passes through the top of the vacuum feed cylinder 2 and communicates with the interior of the vacuum feed cylinder 2. The end of the suction pipe 3 is connected to the side of the vacuum feed cylinder 2; the end of the suction pipe 3 away from the vacuum feed cylinder 2 is tapered, allowing for quick insertion. In the material pile, the suction pipe 3 smoothly enters the depth of the material, and the subsequent straight pipe section continuously and stably sucks up the material, improving the suction efficiency. The bottom end of the vacuum feeding cylinder 2 is connected to a trapezoidal discharge port 5. The bottom end of the trapezoidal discharge port 5 is connected to a rectangular solenoid valve outlet 6. The bottom diameter of the trapezoidal discharge port 5 is smaller than the top diameter. Its purpose is to gather the material into a smaller outlet, which facilitates connection with the solenoid valve outlet 6 and further material transfer. The bottom end of the solenoid valve outlet 6 is connected to a cylindrical horizontally arranged distribution cylinder 7. The bottom end of the distribution cylinder 7 is evenly provided with support columns 8. The distribution cylinder 7 is equipped with a discharge component 9.

[0023] The discharge assembly 9 includes a spiral blade 10 rotatably disposed inside the distribution cylinder 7. The edge of the spiral blade 10 is tightly fitted against the inner wall of the distribution cylinder 7, with a very small gap between them. This prevents material from leaking or accumulating through the gap between the spiral blade 10 and the inner wall of the distribution cylinder 7, ensuring that the spiral blade 10 exerts a uniform force on the material. The material moves along the distribution cylinder 7 in a stable spiral trajectory with a uniform flow rate and no jamming, ensuring a stable material flow at the discharge port 16. This also helps to ensure that the spiral blade 10 is subjected to balanced force when rotating inside the distribution cylinder 7, preventing deformation or vibration of the blade due to uneven local force. The upper side of one side of the distribution cylinder 7 is connected to the bottom end of the solenoid valve outlet 6, and the lower side of the other side of the distribution cylinder 7 is connected to... The discharge port 16 runs vertically through the vacuum pump 4. When the vacuum pump 4 is started, it will quickly extract the air from the vacuum feeding cylinder 2 using its suction end, creating a negative pressure inside the cylinder. The valve of the suction pipe 3 will be opened, and the material to be sucked in will be drawn into the vacuum feeding cylinder 2 under the action of the pressure difference. The discharge assembly 9 also includes a drive motor 11 fixed on the side of the distribution cylinder 7. The output end of the drive motor 11 rotates through the side of the distribution cylinder 7 and is connected to the end of the spiral blade 10. When the drive motor 11 is started, its output end drives the spiral blade 10 to start rotating at a uniform speed. Under the push of the spiral blade 10, the material moves steadily along the spiral trajectory inside the cylinder, and finally achieves uniform and stable discharge from the discharge port 16.

[0024] like Figure 1 , 3As shown in Figure 4, a material conveying assembly 12 is provided inside the vacuum feeding cylinder 2. The material conveying assembly 12 includes a rotary motor 13 fixed to the side of the vacuum feeding cylinder 2 and a material distributing fan 14 that is laterally rotated inside the vacuum feeding cylinder 2. The output end of the rotary motor 13 rotates through the vacuum feeding cylinder 2 and is connected to the end of the material distributing fan 14. When the rotary motor 13 is started, its output end will drive the material distributing fan 14 to rotate, which makes it easier to push the material accumulated in the vacuum feeding cylinder 2 into the trapezoidal discharge port 5, enhance the flowability of materials with poor flowability, and facilitate material discharge.

[0025] like Figure 1-4 As shown, an inclined filter plate 15 with a handle is inserted inside the vacuum feeding cylinder 2 for easy installation, disassembly and cleaning. The end of the suction pipe 3 is located between the inclined filter plate 15 and the distribution fan blade 14. The filter plate 15 is set to prevent the material from being sucked into the suction end of the vacuum pump 4. When the material is sucked into the vacuum feeding cylinder 2, the material will hit the filter plate 15 due to the suction inertia and will not be able to pass through the filter mesh, thus falling to the collection area at the bottom of the cylinder. This can prevent the material from entering the suction end of the vacuum pump 4 and effectively prevent the vacuum pump 4 from being damaged or its normal suction function from being affected by the accumulation and blockage of the material.

[0026] In practical use, close the solenoid valve outlet 6 to ensure a closed environment inside the vacuum feeding cylinder 2, start the vacuum pump 4, insert the conical head of the suction pipe 3 deep into the material pile, and open the suction pipe 3 switch valve. The material will be sucked in due to the negative pressure formed inside the vacuum feeding cylinder 2. During the suction process, the material will impact the inclined filter plate 15 due to inertia. Some of the material will fall to the trapezoidal discharge pipe 5 and the solenoid valve outlet 6, while the other part will accumulate on the distribution fan blades 14. Start the drive motor 11, and its output end will rotate to drive the spiral blades 10. The material begins to rotate at a constant speed. After the adsorption of the material ends, the solenoid valve outlet 6 is opened, and the material will be conveyed from the solenoid valve outlet 6 into the distribution cylinder 7. The rotary motor 13 is started, and its output end will drive the distribution fan blade 14 to rotate, which makes it easier to push the material in the vacuum feeding cylinder 2 into the trapezoidal discharge port 5, enhance the flowability of the material with poor flowability, and facilitate the discharge. The material conveyed into the distribution cylinder 7 will move forward along the spiral trajectory inside the distribution cylinder 7 under the push of the spiral blade 10, so as to achieve uniform and stable discharge from the discharge port 16.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
