[0002] Dry-type transformer coil casting is a key link in the production of dry-type transformers. Its quality directly affects the performance and reliability of the transformer. Epoxy resin is one of the most commonly used materials for dry-type transformer coil casting. It has good insulation properties, mechanical strength and heat resistance, can effectively protect the coil and improve the reliability of the transformer. Curing agent is an indispensable material in the epoxy resin casting process. It can react chemically with epoxy resin to solidify the epoxy resin and form a solid insulating layer. Filler is a material added to improve the performance of epoxy resin. Commonly used fillers include quartz powder, alumina powder, silicon powder, etc. Fillers can improve the mechanical strength, heat resistance and thermal conductivity of epoxy resin, and reduce the shrinkage rate and cost of epoxy resin.

[0003] The mixing equipment for casting dry-type transformer coils plays a vital role in the production process. When mixing epoxy resin and fixative, a stirring shaft is usually required to stir and mix the epoxy resin and fixative. However, the raw materials in the mixing tank are easy to adhere to the inner wall of the mixing tank and are difficult to clean, which easily causes waste. In addition, materials from different batches dry on the inner wall of the mixing tank, which will cause cross-contamination and affect product quality. Summary of the invention

[0012] 3. The present invention provides an extrusion assembly. When the rotating block rotates following the stirring shaft, the rotating block drives the rotating blade to rotate. At the same time, the centrifugal force causes the arc plate to slide toward one side of the ejector pin, so that the ejector pin squeezes the bubbles floating on the surface of the raw material through the through hole, thereby puncturing the bubbles. At the same time, when the arc plate slides toward one side of the extrusion plate due to the centrifugal force, the arc plate drives the circular arc plate into the placement groove through the connecting rod.

After the epoxy resin and curing agent in the tank body are mixed, the control valve is opened to connect the external pipeline with the discharge pipe, so that the raw materials in the tank body are discharged through the discharge pipe for casting the dry transformer coil. At the same time, when the tank body is subsequently cleaned, a large amount of clean water is added to the tank body for flushing. The water flow in the tank body is continuously discharged through the discharge pipe, and the scraper mechanism is impacted by the water flow, so that the scraper mechanism moves on the round rod, so that the scraper mechanism cleans the inner wall of the discharge pipe, thereby avoiding a large amount of raw materials remaining on the inner wall of the discharge pipe when the mixed raw materials are discharged, and then drying on the inner wall of the discharge pipe.

At the same time, the stirring shaft 51 drives the stirring frame 52 to rotate in the tank body 1. After the mixed raw materials in the tank body 1 are discharged, the inner wall of the tank body 1 can be cleaned by the contact mechanism 54. At the same time, when the raw materials are mixed, the bubbles generated when the raw materials are stirred and mixed can be eliminated by the cleaning mechanism 55. After the raw materials are mixed, the mixed raw materials are discharged through the discharging component 6, and the stirring shaft 51 is driven by the output end of the motor 4 to rotate in the inner cavity of the tank body 1, so that the connecting plate 543 is separated from the sliding groove 541, so that the connecting plate 543 drives the scraper 545 to clean and scrape the raw materials remaining on the inner wall of the tank body 1. By setting the angle of the scraper 545 to be greater than the rubber plate 544, the scraper 545 can contact and scrape the raw materials solidified on the inner wall of the tank body 1 when the scraper 545 rotates with the stirring frame 52, so that part of the raw materials solidified on the inner wall of the tank body 1 can be scraped off. At the same time, by setting the rubber plate 544 against the inner wall of the tank body 1, the scraper After 545 scrapes the inner wall of the tank body 1, the scraper 545 first scrapes off part of the dried raw materials, and then the rubber plate 544 contacts and cleans the residual raw materials after the scraper 545 has scraped, so as to avoid that after the raw materials are mixed, part of the raw materials still remain on the inner wall of the tank body 1, thereby preventing the raw materials from being dried and solidified. When different batches of raw materials are subsequently processed, cross contamination occurs between the materials of different batches, affecting the product quality. At the same time, by setting the rubber plate 544 to scrape against the inner wall of the tank body 1 for a long time, it is avoided that the scraper 545 scrapes against the inner wall of the tank body 1 for cleaning and scratching, which will cause damage to the inner wall of the tank body 1, thereby interfering with the service life of the tank body 1. When the epoxy resin and the curing agent are mixed, a large number of bubbles will be generated on the surface of the raw materials during stirring. When the raw materials are mixed, the stirring shaft 51 drives the rotating blade 552 to rotate in the tank body 1 through the rotating block 551, so that the arc plate 553 contacts the bubbles floating on the surface of the raw materials, and at the same time, the bubbles floating on the surface of the raw materials are scraped off. At the same time, when the stirring shaft 51 drives the rotating blade 552 to rotate, the extrusion component 554 uses the centrifugal force to squeeze the bubbles floating on the surface of the raw materials through the through hole 555, so that the bubbles floating on the surface of the raw materials are eliminated; When the rotating block 551 rotates following the stirring shaft 51, the rotating block 551 drives the rotating blade 552 to rotate, and at the same time, the arc plate 553 slides toward the side of the ejector pin 5542 through the centrifugal force, so that the ejector pin 5542 squeezes the bubbles floating on the surface of the raw material through the through hole 555, thereby puncturing the bubbles. At the same time, when the arc plate 553 slides toward the side of the extrusion plate 5541 through the centrifugal force, the arc plate 553 drives the circular arc plate 5546 to enter the placement groove 5548 through the connecting rod 5545. At the same time, when the mixing work is completed, the stirring shaft 51 stops rotating. The arc plate 553 is reset by the stretching of the second spring 5544, so that the arc plate 553 moves to the side away from the extrusion plate 5541. At the same time, the arc plate 553 drives the circular arc plate 5546 to clean the side of the arc plate 553 through the connecting rod 5545, so as to avoid the bubbles floating on the surface of the raw material being punctured by the ejector pin 5542 and splashing on the side of the arc plate 553 to produce residues when the bubbles burst. The circular arc plate 5546 is evenly provided with clearance grooves 5547, so as to avoid the interference between the circular arc plate 5546 and the ejector pin 5542 when the arc plate 5546 is cleaning the arc plate 553. After the epoxy resin and curing agent in the tank body 1 are mixed, the control valve 62 is opened to connect the external pipe with the discharge pipe 61, so that the raw materials in the tank body 1 are discharged through the discharge pipe 61 for casting the dry transformer coil. At the same time, when the tank body 1 is subsequently cleaned, a large amount of clean water is added to the tank body 1 for flushing. The water flow in the tank body 1 is continuously discharged through the discharge pipe 61, and the scraper mechanism 67 is impacted by the water flow, so that the scraper mechanism 67 moves on the round rod 65, so that the scraper mechanism 67 cleans the inner wall of the discharge pipe 61, thereby avoiding a large amount of raw materials remaining on the inner wall of the discharge pipe 61 when the mixed raw materials are discharged, and then drying on the inner wall of the discharge pipe 61; When adding clean water to the tank body 1 for cleaning, the impact of the water flow causes the circular plate 671 to move on the round rod 65, so that the circular plate 671 drives the bent plates 673 on both sides to clean the inner wall of the discharge pipe 61. At the same time, arc grooves 672 are evenly opened on the side of the circular plate 671 to avoid interference with the normal discharge of the water flow. At the same time, the circular plate 671 and the bent plate 673 are both made of rubber. After the tank body 1 is cleaned, the clean water in the tank body 1 is discharged through the discharge pipe 61. When the impact force of the water flow on the circular plate 671 is less than the tensile force of the third spring 66, the circular plate 671 drives the bent plate 673 to move toward the connecting frame 64, so that the circular plate 671 drives the bent plate 673 to collide with the connecting frame 64, so that the water stains attached to the bent plate 673 are shaken off by the vibration generated by the collision, and a plurality of notches 674 are opened on the bent plate 673 to avoid a large amount of excess water stains remaining on the side of the bent plate 673.
