Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 3 In an embodiment of the utility model, an esterification kettle capable of automatic feeding includes a reactor 1, the top of the reactor 1 is connected to a first discharge pipe 2, the top of the reactor 1 is located on one side of the first discharge pipe 2 and is also connected to a second discharge pipe 4, and also includes a discharge mechanism 3 arranged on the first discharge pipe 2.

[0019] The feeding mechanism 3 includes a transmission unit and a limiting unit. The limiting unit is used to limit the rotation of the transmission unit. The transmission unit is used to sequentially and quantitatively add raw materials to the reactor 1.

[0020] The transmission unit includes a rotating rod 301, a first gear 302, a second gear 303, a third gear 304, and a sealing plate 308; the rotating rod 301 is axially slidably installed on the inner wall of the first discharge tube 2 and extends to the outer wall of the first discharge tube 2, and the rotating rod 301 is used to drive the first gear 302 to rotate; the first gear 302 is rotatably installed on the outer wall of the first discharge tube 2 and sleeved on the outer wall of the rotating rod 301, and the first gear 302 is used to give the second gear 303 and the third gear 304 rotational thrust; the second gear 303 and the third gear 304 are rotatably installed on the outer wall of the first discharge tube 2, and the second gear 303 and the third gear 304 are used to synchronously drive the sealing plate 308 to rotate; the sealing plate 308 is fixed on the outer wall of the shaft of the second gear 303 and is located on the inner side of the first discharge tube 2, and the sealing plate 308 is used to provide a barrier seal for the movement of raw materials.

[0021] The limiting unit includes a limiting block 305, a limiting groove 306, and a positioning rod 307; the limiting block 305 is fixed on the outer wall of the rotating rod 301 and extends to the inner side of the first gear 302, and the limiting block 305 is used to transmit the rotational force from the rotating rod 301 to the first gear 302; the limiting groove 306 is opened on the outer wall of the first discharge tube 2, and the limiting groove 306 is used to provide docking space for the movement of the limiting block 305 so as to limit the rotation of the rotating rod 301; the positioning rod 307 is fixed on the end of the rotating rod 301 and extends to the inside of the first discharge tube 2, and the positioning rod 307 is used to limit the maximum moving distance of the rotating rod 301.

[0022] In this embodiment, when raw materials are added into the reactor 1, by applying outward pulling force to the rotating rod 301, the rotating rod 301 subjected to the force will synchronously drive the limit block 305 to move outward, so that the limit block 305 moves out of the inner side of the limit groove 306, thereby releasing the rotation limit of the rotating rod 301. At this time, the rotating rod 301 can be given a rotational force, and the rotating rotating rod 301 transmits the rotational force to the first gear 302 through the limit block 305, so that the first gear 302 rotates with the rotation of the rotating rod 301. The rotating first gear 302 will first apply a rotational force to the third gear 304 through the outer wall tooth block, so that the third gear 304 drives a sealing plate 308 to rotate, quantitatively placing a space between the two sealing plates 308. The raw materials are introduced into the interior of the reactor 1 to complete the quantitative automatic feeding of the raw materials, and the continued rotation of the rotating rod 301 and the first gear 302 will give the third gear 304 a 180-degree rotational force, thereby resetting the third gear 304 and the sealing plate 308. At this time, the first gear 302 will engage with the outer wall of the second gear 303, thereby giving the third gear 304 a rotational force, causing the sealing plate 308 fixed to the third gear 304 to rotate, thereby introducing the raw materials in the first discharge pipe 2 between the two sealing plates 308 until the sealing plate 308 rotates 180 degrees and resets, completing the quantitative feeding of the raw materials. In this way, the quantitative feeding operation of the raw materials is completed, and there is no need to weigh the raw materials for addition, which further improves work efficiency. It should be noted that a rubber gasket is provided on the inner side of the sealing plate 308 and the first discharge pipe 2 to increase the sealing and friction between the first discharge pipe 2 and the sealing plate 308.

[0023] Please refer to Figure 1-Figure 3The outer wall of the positioning rod 307 is a "T"-shaped structure as a whole. The inner wall of the reactor 1 is formed with a sliding groove for axial movement of the positioning rod 307. The outer wall of the limit block 305 matches the inner side of the limit groove 306. The outer wall of the limit block 305 is slidingly connected to the inner side of the first gear 302. The outer wall tooth blocks of the first gear 302 are distributed 180 degrees on the outer wall of the first gear 302. The second gear 303 and the third gear 304 are distributed up and down with the axis of the first gear 302 as the midpoint. There are two sealing plates 308, and the two sealing plates 308 are respectively fixed to the outer walls of the shafts of the second gear 303 and the third gear 304. The inner wall of the first discharge pipe 2 is formed with a rotating space for the sealing plate 308 to rotate.

[0024] In this embodiment: through this structure, after the first gear 302 rotates 360 degrees, the first gear 302 and the third gear 304 can be given a rotational thrust of 180 degrees respectively, so that the two sealing plates 308 can be flipped, and the raw materials between the two sealing plates 308 can be quantitatively added, and the reactor 1 can be automatically fed with quantitative raw materials. After the feeding is completed, the rotating rod 301 is given a thrust again to make the limit block 305 and the limit groove 306 dock, thereby completing the rotation limit of the rotating rod 301 and the first gear 302.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
