Description

Technical Field

[0001] This utility model relates to the field of insulating varnish mixing technology, specifically to a mixing device for insulating varnish production. Background Technology

[0002] Insulating varnish, also known as insulating coating, is a type of coating with excellent electrical insulation properties. It is mainly based on high molecular polymers and can be cured into an insulating film or insulating whole under certain conditions. It belongs to the special type of varnish. The basic characteristic of insulating varnish is that it transmits the effects and influences of electricity through induction rather than conduction. It has good electrochemical, thermal, mechanical and chemical properties. It is mostly clear varnish, but there are also colored varnishes. When producing it, it needs to be mixed appropriately for efficient production operations.

[0003] According to application number CN202123328894.1, a mixing device for insulating varnish raw materials for cable production is provided. The device is easy to move by the setting of casters; the device can be prevented from vibrating and displacing during operation by the setting of support components; and the mixing component and control component can be set to control the mixing direction of the mixing component to rotate back and forth, so as to make the mixing uniform.

[0004] However, the following problems still exist in actual use:

[0005] (1) The stirring component cannot be raised or lowered during use, which makes the equipment inflexible when handling materials of different heights or layers. When the materials to be mixed are distributed in layers in the container, the fixed-height stirring component cannot effectively cover all material layers, which may lead to uneven mixing. It also limits the applicability of the equipment in containers of different capacities, reducing the versatility and working efficiency of the equipment.

[0006] (2) During mixing, the inner wall and bottom of the container cannot be scraped. As a result, the material adhering to the wall and bottom of the container not only affects the mixing effect, but also increases the difficulty of cleaning the equipment. In scenarios where materials need to be changed frequently, incomplete cleaning will lead to cross-contamination. The material adhering to the wall and bottom of the container cannot be fully utilized, resulting in a waste of resources.

[0007] Therefore, this utility model introduces a mixing device for the production of insulating varnish. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 3 A mixing device for producing insulating varnish includes a mixing tank 3 and a connecting slide plate 12. A lifting mixing mechanism 20 is provided on the outer surface of the mixing tank 3. The lifting mixing mechanism 20 includes a rectangular block 7, an L-shaped fixing plate 8, a first servo motor 9, a half gear 10, a gear plate 11, a compression spring 13, and a spring rod 14. The right side of the rectangular block 7 is fixedly installed to the outer surface of the mixing tank 3. The front side of the L-shaped fixing plate 8 is fixedly connected to the back side of the rectangular block 7. The front side of the first servo motor 9 is fixedly installed to the back side of the L-shaped fixing plate 8. The inner side of the half gear 10... The toothed plate 11 is fixedly connected to the outer surface of one end of the output shaft of the first servo motor 9. The left side of the toothed plate 11 meshes with the outer surface of the half gear 10. One end of the compression spring 13 is fixedly installed inside the rectangular block 7. One end of the elastic rod 14 is fixedly installed inside the rectangular block 7. The right side of the toothed plate 11 is fixedly installed to the left side of the connecting slide plate 12. The outer surface of the connecting slide plate 12 is slidably connected to the inner wall of the rectangular block 7. The bottom of the connecting slide plate 12 is fixedly installed to one end of the compression spring 13. The bottom of the connecting slide plate 12 is fixedly installed to one end of the elastic rod 14.

[0026] Specifically, the first servo motor 9 provides stable power output, and the half gear 10 converts this rotational power into reciprocating motion of the toothed plate 11, the compression spring 13, and the elastic rod 14, thereby achieving efficient stirring of the materials in the mixing tank 3. The combined use of the compression spring 13 and the elastic rod 14 enhances the stability of the mixing device and buffers the impact. The compression spring 13 and the elastic rod 14 provide additional support and restoring force for the connecting slide plate 12, so that even if a large resistance is encountered during the stirring process, the device can maintain stable operation, while reducing mechanical wear and noise.

[0027] Please see Figure 4The mixing tank 3 is equipped with a scraping mechanism 21. The scraping mechanism 21 includes a receiving plate 15, a second servo motor 16, a connecting shaft 17, a stirring blade 18, and a scraping plate 19. The bottom of the receiving plate 15 is fixedly installed with the top of the connecting slide plate 12. The bottom of the second servo motor 16 is fixedly installed with the top of the receiving plate 15. One end of the connecting shaft 17 is fixedly installed with one end of the output shaft of the second servo motor 16. One side of the stirring blade 18 is fixedly installed with the outer surface of the connecting shaft 17. The inner ring of the scraping plate 19 is fixedly connected with one side of the stirring blade 18. The outer surface of the connecting shaft 17 is rotatably connected with the inside of the cover plate 4. The outer ring of the stirring blade 18 is in contact with the inner wall of the mixing tank 3.

[0028] Specifically, the combination of the second servo motor 16 and the connecting shaft 17 achieves precise control of the stirring speed and direction. The second servo motor 16 provides stable power output, which drives the stirring blade 18 to rotate through the connecting shaft 17, thus achieving efficient stirring of the insulating varnish material. At the same time, the precise control characteristics of the second servo motor 16 make the stirring process more flexible, and the stirring speed can be adjusted as needed. Through the fixed connection between the stirring blade 18 and the scraper 19, the dual effects of stirring and scraping are achieved simultaneously. During the rotation of the stirring blade 18, it not only stirs the insulating varnish material, but also drives the scraper 19 to move along the inner wall of the mixing tank 3, effectively scraping away residual materials and improving mixing efficiency and mixing quality.

[0029] Please see Figure 1 and Figure 2 A cover plate 4 is fixedly installed inside the top of the mixing tank 3. A feed inlet 5 is opened inside the cover plate 4. A discharge pipe 6 is fixedly installed inside the bottom of the mixing tank 3. Support plates 2 are fixedly installed around the mixing tank 3. A bottom plate 1 is fixedly installed at the bottom of the support plates 2.

[0030] Specifically, by fixing the cover plate 4 inside the top of the mixing tank 3, the purpose of sealing the mixing tank 3 and protecting the internal mixing process is achieved. The cover plate 4 not only prevents materials from splashing out during the mixing process, but also keeps the inside of the mixing tank 3 clean and hygienic, ensuring the quality of the insulating varnish production. The inlet 5 inside the cover plate 4 enables convenient addition of materials to the mixing tank 3. The design of the inlet 5 allows operators to easily pour the insulating varnish raw materials into the mixing tank 3, while avoiding the mixing of external impurities during the mixing process, ensuring the purity of the materials. The outlet pipe 6 can discharge the mixed materials. Furthermore, the use of the support plate 2 and the bottom plate 1 ensures the stability of the device during use.

[0031] Working principle: In use, the pre-treated materials can be placed into the mixing tank 3 through the feed port 5 opened inside the cover plate 4. After the electrical connection with the external power source, the second servo motor 16 fixedly installed on the upper surface of the receiving plate 15 can be started. Through the power of the second servo motor 16, the connecting shaft 17 fixedly installed at one end of the output shaft of the second servo motor 16 can be rotated inside the mixing tank 3. The stirring blade 18 is fixedly installed on the outer surface of the connecting shaft 17, and the scraper 19 is fixedly installed on one side of the stirring blade 18. They can rotate synchronously, thereby mixing the materials that have entered the mixing tank 3.

[0032] While mixing materials, the electrical connection of an external power source starts the first servo motor 9, which in turn drives the rotation of the half gear 10 fixedly mounted on the outer surface of the output shaft of the first servo motor 9. When the half gear 10 rotates, it meshes with the toothed plate 11, allowing the connecting slide plate 12 fixedly mounted on the right side of the toothed plate 11 to slide on the inner wall of the rectangular block 7. As the position of the connecting slide plate 12 changes, the positions of the connecting shaft 17 and the stirring blade 18 can simultaneously change on the inner wall of the mixing tank 3. This allows for scraping and mixing operations on the inner wall and bottom of the mixing tank 3. Simultaneously, the bottom of the connecting slide plate 12 is fixedly connected to the inside of the rectangular block 7 with a compression spring 13 and a spring rod 14. After the height of the connecting slide plate 12 is raised to a certain level, the half gear 10 and the toothed plate 11 do not mesh. Through the rebound action of the compression spring 13 and the spring rod 14, the position of the connecting slide plate 12 can be lowered, allowing the half gear 10 and the toothed plate 11 to mesh again, thus ensuring the reciprocating lifting and lowering mixing operation inside the mixing tank 3.
