Specific embodiments

[0022] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0023] Example: As Figures 1-4 shown, a raw material quantitative addition device for curing agent production includes a bottom plate 1. A reaction tank 2 is fixedly connected to the middle of the top end of the bottom plate 1. A plurality of feed pipes 7 are installed at the top end of the reaction tank 2. A feed hopper 8 is fixedly connected to the top end of the feed pipe 7. A plurality of mounting frames 3 are fixedly connected to the top end of the bottom plate 1. The plurality of mounting frames 3 are arranged in a circle around the reaction tank 2. A raw material barrel 4 is installed at the top end of the mounting frame 3, and the bottom of the raw material barrel 4 extends above the feed hopper 8. A partition plate 15 is fixedly connected inside the raw material barrel 4. A blanking port 19 is opened in the middle of the partition plate 15. An electric valve 14 is installed at the bottom of the raw material barrel 4. A blocking mechanism is installed on the partition plate 15. According to different raw materials, the position of the partition plate 15 in the raw material barrel 4 is adjusted to ensure the input amount of the raw material.

[0024] Raw materials are put into the raw material barrel 4. The raw materials fall to the bottom of the raw material barrel 4 along the blanking port 19. After a certain period of time, the area between the electric valve 14 and the partition plate 15 in the raw material barrel 4 is filled with raw materials. Then, the blocking mechanism closes the blanking port 19, opens the electric valve 14, and the raw materials are discharged from the raw material barrel 4, enter the feed hopper 8, and enter the reaction tank 2 along the feed pipe 7, realizing the quantitative addition of raw materials and ensuring the quality of the product.

[0025] Specifically, as Figure 3 and Figure 4 shown, the blocking mechanism includes a second motor 18, and the second motor 18 is fixedly connected to the top end of the partition plate 15. An electromagnetic brake is arranged inside the second motor 18. The output end of the second motor 18 is fixedly connected to a baffle plate 17, and the baffle plate 17 is arranged below the blanking port 19. When the second motor 18 works to drive the baffle plate 17 to move, when the baffle plate 17 moves below the blanking port 19, the blanking port 19 is closed. When the baffle plate 17 is misaligned with the blanking port 19, the blanking port 19 is opened to realize blanking.

[0026] Specifically, as Figure 4As shown in the figure, a limit ring 16 is fixedly connected to the bottom end of the partition plate 15, and the end of the material baffle 17 is slidably connected to the inside of the limit ring 16. The limit ring 16 is divided into multiple sections to prevent raw materials from accumulating inside the limit ring 16 and affecting the movement of the material baffle 17. The material baffle 17 moves inside the limit ring 16, and the limit ring 16 supports the end of the material baffle 17, reducing the load at the connection between the material baffle 17 and the second motor 18.

[0027] Specifically, as Figure 1 and Figure 3 shown in the figure, a winch 5 is fixedly installed at the top end of the mounting frame 3. A steel wire rope is arranged on the winch 5. The bottom end of the steel wire rope is fixedly connected to a connecting rod 12, and the connecting rod 12 is fixedly connected to the top end of the raw material barrel 4. Sliders 13 are fixedly connected to both sides of the raw material barrel 4, and the sliders 13 are slidably connected to the inside of the mounting frame 3. When the winch 5 operates, the steel wire rope is released, and the sliders 13 slide downward along the mounting frame 3, reducing the height of the raw material barrel 4, which is convenient for adding materials to the raw material barrel 4 and makes it more convenient to use.

[0028] Specifically, as Figure 1 and Figure 2 shown in the figure, a connecting pipe 6 is rotatably connected to the bottom of the feed pipe 7, and the connecting pipe 6 is fixedly connected to the top end of the reaction tank 2. A driven gear 9 is fixedly connected to the outside of the feed pipe 7. The outside of the driven gear 9 is meshed with a driving gear 10. The bottom end of the driving gear 10 is equipped with a first motor 11, and the first motor 11 is fixedly connected to the top end of the reaction tank 2. An electromagnetic brake is arranged inside the first motor 11. When the first motor 11 operates, it drives the driving gear 10 to rotate. The rotating driving gear 10 makes the feed pipe 7 rotate inside the connecting pipe 6 through the driven gear 9, thereby changing the direction of the feed hopper 8 and preventing the descending raw material barrel 4 from interfering with the feed hopper 8.

[0029] Working principle: Fill the raw material barrel 4 with raw materials. When the winch 5 operates, the slider 13 moves upward along the mounting frame 3, and thus the raw material barrel 4 moves to the top of the mounting frame 3. When the first motor 11 operates, it drives the driving gear 10 to rotate. The rotating driving gear 10 makes the feed pipe 7 rotate inside the connecting pipe 6 through the driven gear 9, so that the feed hopper 8 moves to the lower part of the discharge port of the raw material barrel 4. The raw materials in the raw material barrel 4 fall along the material dropping port 19 to the bottom of the raw material barrel 4. After a certain period of time, the area between the electric valve 14 and the partition plate 15 in the raw material barrel 4 is filled with raw materials. When the second motor 18 operates, it drives the material baffle 17 to move. When the material baffle 17 moves to the lower part of the material dropping port 19, it closes the material dropping port 19. Open the electric valve 14, and the raw materials are discharged from the raw material barrel 4, enter the feed hopper 8, and then enter the reaction tank 2 along the feed pipe 7.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
