Description

Technical Field

[0001] This utility model relates to the field of sealant production technology, specifically to an automated control device for the production of sealant for photovoltaic modules. Background Technology

[0002] Alcohol-free sealants are sealants based on alcohol-free silicone. They contain no organic solvents and do not release alcohols during curing, thus offering advantages such as low volatility, low odor, and environmental friendliness. Alcohol-free sealants typically possess good weather resistance, chemical resistance, electrical insulation, and excellent adhesion properties, making them suitable for sealing and bonding photovoltaic module frames and junction boxes.

[0003] The texture of de-alcoholized sealant is usually paste or liquid with a certain degree of fluidity. During the production process, the material is stirred by a stirring rod to make it fully mixed. However, some impurities in the material may not be fully integrated, and there may be undispersed particles due to uneven mixing. These impurities will affect the quality of the sealant and reduce its viscosity. Utility Model Content

[0026] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0027] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] Combined with appendix Figures 2 to 4 As shown, an automated control device for the production of sealant for photovoltaic modules includes a support frame 1, on which a mixing tank 2 is fixedly mounted. A discharge pipe 3 is connected to the bottom of the mixing tank 2. The bottom of the mixing tank 2 has an inverted conical structure, which facilitates better discharge of the mixture and reduces residue within the mixing tank 2. The discharge pipe 3 is located at the center of the bottom of the mixing tank 2. A sealing lid 4 is connected to the top of the mixing tank 2. A flange 22 is provided on the outer wall of the mixing tank 2, and a flange 23 is provided on the outer wall of the sealing lid 4. A sealing ring 24 is provided on the sealing lid 4. A sealing groove 25, adapted to the sealing ring 24, is formed on the top surface of the mixing tank 2. Through the cooperation of bolts and nuts, the bolts pass through the flange 22 and flange 23 respectively and are threadedly connected to the nuts, allowing the sealing lid 4 to be tightly installed on the mixing tank 2. Simultaneously, the sealing ring 24 is engaged within the sealing groove 25, ensuring a tight seal during the mixing process and preventing impurities from entering the mixing tank 2.

[0029] To improve the uniformity of the mixture, combined with the attached Figure 4As shown, the sealed lid 4 is equipped with a mixing structure for mixing materials. The mixing structure includes a motor 5 fixedly mounted on the sealed lid 4. The output end of the motor 5 is connected to a mixing rod 6. The mixing rod 6 has a first mixing blade 7, a second mixing blade 8, and a third mixing blade 9 arranged from top to bottom. The first mixing blade 7 has a double-helix structure. The second mixing blade 8 consists of multiple plates whose length gradually decreases from top to bottom. The third mixing blade 9 consists of multiple plates arranged at equal intervals and of the same length. The third mixing blade 9 rotates within the discharge pipe 3. The motor 5 drives the mixing rod 6 to rotate, thereby mixing the mixture. This multi-stage mixing blade design ensures that the sealant raw materials are fully dispersed and mixed during the mixing process, improving mixing efficiency and uniformity.

[0030] The sealant mixture may contain some impurities. To further enhance the quality and performance of the sealant, additional measures should be taken, such as adding... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a sleeve 10 is connected to the discharge pipe 3. A threaded groove 17 is spirally provided on the outer wall of the discharge pipe 3. The sleeve 10 is threadedly connected to the discharge pipe 3. This connection design facilitates the assembly and disassembly of the sleeve 10. A connector 11 is rotatably provided at the bottom center of the sleeve 10. Several filter holes 12 are arrayed around the connector 11 on the bottom surface of the sleeve 10. A cleaning brush 13 is connected to the outer wall of the connector 11. A slot 14 is provided at the center of the connector 11. Multiple slots 15 are arrayed circumferentially within the slot 14. A locking block 16 is provided at the bottom of the stirring rod 6, which is adapted to the slots 15. The locking block 16 engages within the slots 15, thus driving the connector 11 to rotate synchronously when the stirring rod 6 rotates. This allows the cleaning brush 13 to clean the bottom surface of the sleeve 10, clearing the filter holes 12, preventing blockage, and ensuring smooth discharge.

[0031] Combined with appendix Figure 5 As shown, one end of the sleeve 10 is equipped with a valve 18, which controls the discharge of the sealant mixture. When the valve 18 is opened, the mixture is filtered to remove impurities under the action of the filter hole 12 and then discharged, ensuring the purity of the sealant mixture. At the same time, the sleeve 10 is equipped with an annular plate 19 with the same inner diameter as the discharge pipe 3. The sleeve 10 is equipped with a sealing ring 20, which is located between the annular plate 19 and the wall of the sleeve 10. The sealing ring 20 can ensure the sealing of the connection between the discharge pipe 3 and the sleeve 10 and prevent the material from seeping out.

[0032] Combined with appendix Figure 2 and Figure 4 As shown, a scraper 21 is connected to the stirring rod 6 via a connecting rod. The scraper 21 is made of soft silicone, and one end of it abuts against the inner wall of the mixing tank 2. Driven by the stirring rod 6, the scraper 21 rotates to scrape off the mixture adhering to the inner wall of the mixing tank 2, reducing the waste of sealant raw materials.
