Description

Technical Field

[0001] The utility model relates to the field of packaging equipment, in particular to a multifunctional multi-column metering and stirring machine with dustproof function. Background Art

[0002] like Figure 5 and Figure 6 As shown, the multi-row machines currently on the market are relatively simple in design, relying primarily on screw rotation for metering. However, this design often proves inadequate when handling materials with poor flowability. To improve material flowability, a horizontal or vertical agitator is often added to the equipment as an auxiliary device. While this additional agitator can improve material flowability to a certain extent, it also increases the complexity of the equipment and makes maintenance more difficult.

[0003] The structure of a screw metering system is relatively simple, primarily relying on a combination of bearings and sealing rings to prevent powder intrusion. However, with the increasing diversity of powder types, traditional sealing methods are becoming increasingly inadequate, particularly for fine powders with large mesh sizes and high dust emission. Because the sealing rings wear slightly over time, these fine powder particles can penetrate the bearings, causing them to become stuck and disrupting normal production.

[0004] While attempts have been made to extend the life of the equipment by optimizing the sealing properties of the seals and using various seal combinations, these measures can only alleviate the problem to a certain extent and cannot completely eliminate the impact of powder leakage on equipment operation. Wear of seals is inevitable, especially in high-frequency, high-intensity production environments, where their lifespan is limited.

[0005] To address the above issues, we have made a series of improvements. Utility Model Content

[0029] like Figure 1-4 As shown, a multifunctional multi-column metering and stirring machine with dust-proof function includes: a screw mechanism 100, a stirring structure 200, a screw reduction motor 300, a stirring motor 400, a screw driving gear 500, a stirring transmission system 600, a powder bin 700 and an air intake structure 800. The top of the screw mechanism 100 is connected to the screw driving gear 500, the screw driving gear 500 is connected to the screw reduction motor 300, the stirring motor 400 is connected to the stirring transmission system 600, the stirring transmission system 600 is connected to the stirring structure 200, the powder bin 700 is located at the lower end of the screw mechanism 100 and the stirring structure 200, and the air intake structure 800 is provided on the screw mechanism 100 and the stirring structure 200.

[0030] The air intake structure 800 includes a screw shaft nitrogen inlet 810 and a stirring shaft air inlet 820 . The screw shaft nitrogen inlet 810 is located at the top of the screw mechanism 100 , and the stirring shaft air inlet 820 is located at the side end of the stirring structure 200 .

[0031] like Figure 2 As shown, the screw mechanism 100 includes: a screw 110, a screw shaft 120, a screw fixing seat 130, a screw shaft bearing 140, a screw shaft driven gear 150 and a screw shaft sealing ring 160. The screw 110 is connected to the screw shaft 120, the screw shaft 120 is fixedly connected to the screw fixing seat 130, the screw shaft 120 is connected to the screw reduction motor 300, the screw shaft bearing 140 and the screw shaft sealing ring 160 are connected to the screw shaft 120, the screw shaft driven gear 150 is connected to the top shaft of the screw shaft 120, and the screw shaft driven gear 150 is connected to the screw driving gear 500.

[0032] like Figure 2 As shown, the stirring structure 200 includes: a stirring shaft 210, a stirring blade 220, a stirring driven gear 230, a stirring shaft bearing 240 and a stirring shaft sealing ring 250. The bottom end of the stirring shaft 210 is provided with a stirring blade 220, the stirring shaft 210 is wrapped and connected with the screw shaft 120, the top end of the stirring shaft 210 is connected to the stirring transmission system 600 through the stirring driven gear 230, and the stirring shaft bearing 240 and the stirring shaft sealing ring 250 are connected to the stirring shaft 210.

[0033] like Figure 3 As shown, the stirring transmission system 600 includes: a stirring transmission shaft 610 and a stirring driving gear 620 , and the stirring driving gear 620 is connected to the stirring motor 400 through the stirring transmission shaft 610 .

[0034] like Figure 4 As shown, the innovation of the present invention lies in the addition of an air intake structure 800, including a screw shaft nitrogen inlet 810 and a stirring shaft air inlet hole 820. The screw shaft nitrogen inlet 810 is located at the top of the screw mechanism 100 and is used to inject positive pressure gas into the screw shaft sealing ring area 161 inside the screw shaft sealing ring 160; the stirring shaft air inlet hole 820 is located at the side end of the stirring structure 200 and is used to inject positive pressure gas into the stirring shaft sealing ring area 251 inside the stirring shaft sealing ring 250.

[0035] The injected positive-pressure gas creates a certain positive-pressure area inside the seal ring. Due to the pressure differential between the inside and outside, the gas continuously diffuses outward, forming an airflow barrier at the gap in the seal ring. This airflow effectively blocks dust from infiltrating the bearing area through the dust inlet 900, thereby preventing dust from entering the bearing and causing a jam. Therefore, the function of the agitator shaft seal ring area 251 is to prevent dust from leaking from the agitator shaft seal ring into the bearing; while the screw shaft seal ring area 161 prevents the same dust leakage from the screw shaft seal ring. The two positive-pressure areas work together to fully protect the sealing of the bearing area, fundamentally resolving the chronic problem of dust intrusion into the bearing in traditional structures.

[0036] By adding an air intake structure and injecting positive pressure gas, the improvement utilizes the principle of airflow barrier to completely block the intrusion of dust, greatly extending the service life of the bearing, which is an effective solution.

[0037] The utility model not only achieves a significant improvement in dust prevention function, but also cleverly integrates the stirring and metering functions into the same device, forming an efficient and simplified design scheme. Traditional multi-column machine equipment is relatively simple in structure and mainly relies on the rotation of the screw for metering. However, when faced with materials with poor fluidity, this design often seems to be inadequate. In order to improve the fluidity of the material, it is usually necessary to add an independent stirring device next to the equipment. Although this external stirring device can improve the fluidity of the material to a certain extent, it also increases the complexity of the equipment, occupies space, and increases the difficulty of maintenance and operation.

[0038] In this design, by organically integrating the stirring structure 200 with the screw mechanism 100, the device achieves the dual functions of stirring and metering within the same system. The stirring motor 400 drives the stirring structure 200 through the stirring transmission system 600, thoroughly stirring the material and maintaining good fluidity before it enters the screw mechanism 100. This integrated design not only enhances the device's versatility but also greatly simplifies the production process, reducing the need for additional stirring equipment.

[0039] Furthermore, this design effectively expands the equipment's applicability and production efficiency, enabling more efficient handling of various materials with poor fluidity, ensuring smooth material delivery while maintaining metering accuracy. This innovative design overcomes many of the limitations of traditional equipment when handling complex materials, achieving a seamless integration of mixing and metering functions, providing users with a more reliable and efficient production tool.

[0040] Through this new design concept, the equipment can not only adapt to a wider range of materials, but also maintain stable performance under high-load production conditions, significantly extend the service life of the equipment, reduce maintenance costs, and bring greater economic benefits and operational convenience to users.

[0041] The above describes the specific implementation of the present invention, but the present invention is not limited thereto. As long as it does not deviate from the purpose of the present invention, the present invention can also have various changes.
