Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to an automatic jujube powder screening and packaging machine. Background Technology

[0002] Jujube powder is a powdered product made from jujubes, rich in various nutrients, and is popular among consumers. In the production process of jujube powder, sieving and packaging are crucial steps, directly affecting product quality and production efficiency. Currently, the sieving and packaging of jujube powder mostly adopts a segmented operation. First, the jujube powder is sieved to remove unqualified clumps, and then the qualified powder is transferred to packaging equipment for packaging. This method requires manual material handling, which not only increases labor intensity but also easily leads to contamination or dust during transportation, affecting product quality and the production environment. Utility Model Content

[0003] This utility model mainly provides an automatic jujube powder screening and packaging machine, which solves the problems of high labor intensity and easy contamination or dust during the transportation of jujube powder, which affect product quality and the production environment when using segmented operation for jujube powder packaging.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An automatic jujube powder screening and packaging machine includes a powder packaging body, a spiral feeding mechanism, a screening mechanism, a grinding mechanism, and a raw material hopper. The outlet of the raw material hopper is connected to the inlet of the spiral feeding mechanism, and the outlet of the spiral feeding mechanism is connected to the inlet of the screening mechanism. The screening mechanism is provided with a coarse powder outlet and a fine powder outlet. The coarse powder outlet is connected to the inlet of the grinding mechanism, and the fine powder outlet is connected to the inlet of the powder packaging body. The outlet of the grinding mechanism is connected to the raw material hopper. The powder packaging body uses existing technology, as long as it can achieve quantitative packaging of the powder. The spiral feeding mechanism can use any existing closed spiral feeder, as long as it can lift and feed the jujube powder in a closed environment. The connections between the components can be made using silicone hoses or rubber hoses, or large-pitch, shallow-corrugated, smooth-walled silicone or rubber corrugated pipes, thereby reducing vibration transmission between the screening mechanism, grinding mechanism, and other components. In operation, the operator pours the jujube powder raw material into the raw material hopper, which then feeds it directly into the screw conveyor through the outlet. The screw conveyor then feeds the powder into the screening mechanism. After screening, the jujube powder that meets the requirements falls through the fine powder outlet into the buffer hopper of the powder packaging unit. The unsuitable jujube powder enters the grinding mechanism through the coarse powder outlet, is ground again, and then returns to the raw material hopper, creating a continuous feeding cycle. This structure, through the coordinated operation of various components, realizes the processes of jujube powder storage, feeding, screening, coarse powder crushing, and packaging, reducing manual intervention, lowering labor intensity, and improving production efficiency. Simultaneously, the direct connection of all components and the use of a closed conveyor system prevent the jujube powder from contacting the external environment, avoiding contamination and dust generation, thus improving product quality. Furthermore, the unsuitable jujube powder after screening is crushed by the grinding mechanism and then returned to the raw material hopper for feeding, ensuring product recycling and preventing jujube powder waste.

[0005] Furthermore, the screening mechanism includes a screening support, a screening base on the screening support, multiple spring assemblies arranged in a ring on the screening base, a screen plate on each spring assembly, a vibrating motor on the lower side of the screen plate, and a screen mesh on the upper side of the screen plate, with a dust cover on the screen mesh; the coarse powder outlet is located on the screen mesh, and the fine powder outlet is located on the screen plate; the feed inlet of the screening mechanism is located on the dust cover. In use, the jujube powder entering the screen mesh through the spiral feeding mechanism is screened and discharged under the drive of the vibrating motor. This structure achieves efficient separation of jujube powder and coarse powder through the vibrating motor and screen mesh, reduces vibration transmission through the spring assemblies, and prevents dust from entering and jujube powder from overflowing.

[0006] Furthermore, the grinding mechanism includes a grinding and feeding pipe, within which a grinding component is rotatably connected. A grinding motor for driving the grinding component to rotate is located at the upper end of the grinding and feeding pipe. An inclined feed pipe is provided on the grinding and feeding pipe, and the feed inlet of the grinding mechanism is located on the inclined feed pipe. The discharge outlet of the grinding mechanism is the lower end of the grinding and feeding pipe. The grinding motor can utilize existing technology, as long as it can drive the grinding component to rotate, thereby crushing the coarse powder, such as a three-phase asynchronous motor or a variable frequency asynchronous motor. In use, the jujube powder discharged through the coarse powder outlet is crushed by the grinding component driven by the grinding motor during the guiding and feeding process through the grinding and feeding pipe before entering the raw material silo. Using this structure, the grinding and feeding pipe can act as a feeding guide for the jujube powder, enabling further crushing of the coarse powder, avoiding dust generation during crushing, preventing connections, and eliminating the need for manual intervention in the entire coarse powder transfer and crushing process.

[0007] Furthermore, the grinding assembly includes a grinding shaft rotatably connected within the grinding feed pipe, and multiple crushing blades are arrayed on the grinding shaft. The specific number of crushing blades is selected according to actual conditions. This structure enables the grinding of coarse powder through the array of multiple crushing blades, and the length of the grinding feed pipe is the crushing distance, effectively ensuring that the coarse powder is fully crushed during its descent.

[0008] Furthermore, the raw material silo is equipped with a sealing cover and a transparent observation window. This structure effectively prevents external dust and impurities from entering and contaminating the jujube powder after the operator loads the raw material into the silo, while also preventing the jujube powder from absorbing moisture and clumping during storage, thus ensuring the quality of the raw materials. The transparent observation window allows the operator to easily observe the material level in the silo, avoiding equipment downtime due to insufficient raw materials and improving production continuity.

[0009] Beneficial effects: The interconnected operation of various components enables the storage, feeding, screening, coarse powder crushing, and packaging of jujube powder, reducing manual intervention, lowering labor intensity, and improving production efficiency. Simultaneously, the direct connection of each component and the use of a closed conveyor system prevent the jujube powder from contacting the external environment, avoiding contamination and dust generation, thus improving product quality. Furthermore, jujube powder that does not meet the screening requirements is crushed by the grinding mechanism and then reintroduced into the raw material silo, ensuring product recycling and preventing waste.

The outlet of the grinding mechanism 4 is connected to the raw material hopper 5. The connections between the components can be made using silicone hoses or rubber hoses, or large-pitch, shallow-corrugated, smooth-walled silicone or rubber corrugated pipes, thereby reducing vibration transmission in components such as the screening mechanism 3 and the grinding mechanism 4. The screening mechanism 3 includes a screening support, a screening base 301 on the screening support, a plurality of spring assemblies 302 arranged in a ring on the screening base 301, a screen plate 303 on the spring assembly 302, a vibration motor 304 on the lower side of the screen plate 303, and a screen mesh 305 on the upper side of the screen plate 303.
