Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to a low-shrinkage resin mixing device. Background Technology

[0002] The uniform mixing of resin raw materials plays a crucial role in the quality of the final product. Resin raw materials are typically composed of various different components, which need to be fully integrated during the mixing process to ensure that the resin product possesses stable properties and good quality.

[0003] Traditional resin mixing devices mostly employ a single stirring structure, resulting in a limited stirring method and range. During the stirring process, resin raw materials tend to concentrate near the stirring area, while materials further away from the stirring area are difficult to mix thoroughly. This can easily lead to resin stratification, preventing the uniform distribution of different resin components.

[0004] In addition, traditional equipment also suffers from the problem of dead zones in the mixing process. Due to the design limitations of the mixing structure, certain areas inside the equipment cannot be reached by the mixing paddle. The resin raw materials in these areas remain stationary for a long time and cannot participate in the overall mixing process, further affecting the uniformity of resin mixing.

[0005] To address the aforementioned issues, we propose a low-shrinkage resin mixing device. Utility Model Content

[0033] Working principle of this utility model:

[0034] Refer to the instruction manual appendix Figures 1-4First, open the feeding valve 21 on the feeding pipe 20, and slowly add the resin raw material to be mixed into the mixing tank 1 through the feeding pipe 20. After the raw material enters the mixing tank 1, start the first motor 11 at the bottom of the mixing tank 1. The output end of the first motor 11 drives the first rotating rod 12 to rotate through the coupling. When the first rotating rod 12 rotates, the conveying auger 14 fixed on its outer wall rotates in the conveying tank 6, lifting the raw material at the bottom of the mixing tank 1 from the bottom of the conveying tank 6 to the top.

The output end of the second motor 17 drives the second rotating rod 18 to rotate through the coupling, thereby causing the second stirring paddle 19 fixed on the outer wall of the second rotating rod 18 to start rotating. The mixing drum 2 is rotated to initially mix the resin raw materials. After a period of initial mixing, the raw materials in the mixing drum 2 flow back into the mixing drum 1 through the second guide pipe 5 under the action of gravity. This cycle is repeated to achieve the circulation of the raw materials between the mixing drum 1 and the mixing drum 2. During the circulation process, the resin raw materials are stirred, which can fully mix the resin, avoid resin stratification, prevent the formation of dead zones, and achieve good and uniform mixing. At the same time, the first stirring paddle 13 on the bottom outer wall of the first rotating rod 12 further stirs and mixes the raw materials gathered at the bottom of the collecting hood 9, further uniformly mixing the resin raw materials. After the resin raw materials are fully mixed and uniform, the first motor 11 and the second motor 17 are turned off, and the discharge valve 23 on the discharge pipe 22 at the bottom of one side of the mixing drum 2 is opened to discharge the mixed resin raw materials from the discharge pipe 22.
