During the manufacturing process of dry-type transformers, the windings usually need to be cast and encapsulated with resin to provide the necessary insulation and protect the windings from environmental influences. Appropriate casting resin can ensure the performance, durability and safety of the transformer. Before casting the resin, it needs to be mixed and stirred, so a proportioning device is needed.

The surface of the vertical rod 83 contacts the bottom of the proportioning bucket 4.

[0024] As a technical optimization scheme of the utility model, by setting up the driving component 8, the mounting seat 81 can effectively fix the electric push rod 82. By starting the electric push rod 82, the vertical rod 83 is driven to tilt through the proportioning bucket 4, so that the resin can be separated from the weighing plate 6 and enter the interior of the feed hopper 2, thereby facilitating the user to load the proportioned resin.

[0025] refer to Figure 1 and Figure 3 The anti-blocking mechanism 9 includes a mounting plate 91, which is fixedly connected to the bottom of the front side of the feed hopper 2. A dual-axis motor 92 is fixedly installed on the top of the mounting plate 91. The output end of the dual-axis motor 92 is fixedly connected to a first bevel gear 93, and the rear side of the first bevel gear 93 is meshedly connected to the second bevel gear 94. A toggle rod 95 is arranged inside the feed hopper 2, and the front side of the toggle rod 95 is meshedly connected to the rear side of the second bevel gear 94.

[0026] As a technical optimization scheme of the utility model, by setting up an anti-blocking mechanism 9, the dual-axis motor 92 can effectively drive the first bevel gear 93 to rotate the second bevel gear 94, and the second bevel gear 94 drives the toggle rod 95 to toggle the inside of the feed hopper 2, thereby preventing the feed hopper 2 from being blocked during feeding, thereby improving the feeding efficiency of the feed hopper 2.

[0027] refer to Figure 1 and Figure 3 The surface of the toggle rod 95 is movably connected with the bearing seat 10, and the bottom of the bearing seat 10 is fixedly connected to the two sides of the top of the mounting plate 91.

[0032] As a technical optimization solution of the utility model, by setting the limit groove 12 and the limit rod 13, the limit rod 13 can be effectively moved up and down inside the limit groove 12, so that the limit rod 13 can limit the weighing plate 6, preventing the weighing plate 6 from tilting or offsetting, thereby improving the accuracy of the weighing plate 6 during detection.

[0033] refer to Figure 1 and Figure 2 Both sides of the inner wall of the mixing bucket 4 are provided with chutes 14, and the inner wall of the chutes 14 is movably connected with a scraper 15.

[0034] As a technical optimization scheme of the utility model, by setting the slide 14 and the scraper 15, when the proportioning bucket 4 is tilted, the user can pull the scraper 15 on the inner wall of the slide 14 to scrape the top of the weighing plate 6, so that the resin is separated from the top of the weighing plate 6, preventing the resin from remaining on the top of the weighing plate 6, thereby facilitating the user to clean the weighing plate 6.

[0035] The working principle and use process of the utility model are as follows: when in use, the user first pours the resin into the mixing bucket 4, and makes the resin fall onto the top of the weighing plate 6, and the resin on the top of the weighing plate 6 is weighed by the weighing sensor 5, and then the weighed data is observed by the display screen 7, so that the user can accurately mix the resin by weight, thereby achieving the effect of the weighing function, improving the accuracy of the resin ratio, and avoiding the influence of the error of the resin on the effect after mixing. When the resin is weighed by the weighing plate 6, the user starts the electric push rod 82 outside the mounting seat 81, and the electric push rod 82 pushes the vertical rod 83 when the mixing bucket is filled with resin. 4 completes the tilting, at which time the weighing plate 6 follows the tilting and makes the resin slide into the inside of the feed hopper 2, thereby improving the feeding speed of the resin. When the resin remains on the top of the weighing plate 6, the user pulls the scraper 15 on the inner wall of the slide 14 to move inward, so that the scraper 15 can scrape the top of the weighing plate 6 to complete the separation of the resin and prevent the resin from remaining on the top of the weighing plate 6. Then the user drives the first bevel gear 93 through the dual-axis motor 92 to rotate the second bevel gear 94, and drives the toggle rod 95 through the second bevel gear 94 to toggle the inside of the feed hopper 2, thereby preventing the feed hopper 2 from being blocked during feeding, thereby improving the feeding efficiency of the feed hopper 2.
