The rotating rod 83, which is rotatably connected to the inner wall of the feed port 3, can rotate. By setting the rotating rod 83, the movable ring 84 and the blades 85 can be driven to rotate inside the feed port 3, thereby dredging the inside of the feed port 3, thereby ensuring the feeding efficiency of the feed port 3 as much as possible. The end of the rotating rod 83 away from the feed port 3 is fixedly connected to a reciprocating motor 82, and the surface of the reciprocating motor 82 is fixedly connected to a mounting block 81. One side of the mounting block 81 is fixedly connected to the upper surface of the reaction tank 2. The reciprocating motor 82 can be mounted on the reaction tank 2 through the mounting block 81. The reciprocating motor 82 can be used to control the rotating rod 83 to rotate, and the reciprocating motor 82 can be used to control the rotating rod 83 to rotate forward and reverse.

[0036] The surface of the rotating rod 83 is provided with two sliding grooves. Sliders 86 are slidably connected to the surfaces of the sliding grooves on both rotating rods 83. Sliders 86 are fixedly connected to the movable ring 84. Sliders 86, slidably connected to the surfaces of the sliding grooves on the rotating rod 83, are movable. Sliders 86 ensure the connection between the movable ring 84 and the rotating rod 83 while also ensuring the movement of the movable ring 84. A fixed rod 87 is slidably connected to the inner wall of the slider 86. A first spring 88 is mounted on the surface of the fixed rod 87. The ends of the first spring 88 are fixedly connected to the slider 86 and the rotating rod 83, respectively. The fixed rod 87 limits the position of the first spring 88, making it easy to control the position of the slider 86.

[0037] like Figure 2 and Figure 7As shown, the connecting device 9 comprises two connecting plates 91 fixedly connected to the surface of the feed port 3 and the cover 10 respectively, and the inner wall of each connecting plate 91 is rotationally connected with a rotating shaft 92. The connecting plates 91 and the rotating shaft 92 can ensure the connection between the cover 10 and the feed port 3 while ensuring that the cover 10 can rotate. The surface of the feed port 3 is fixedly connected with a positioning block 93, the surface of the cover 10 is fixedly connected with an arc-shaped plate 94, and the inner wall of the arc-shaped plate 94 is slidingly connected with a limiting rod 95. The positioning block 93 can be used to position the cover 10 when the cover 10 is used to close the feed port 3, and the limiting rod 95 can be used to limit the position of the cover 10 after the cover 10 is used to close the feed port 3.

[0038] The end of the limiting rod 95 away from the positioning block 93 is fixedly connected with a pull plate 96, the surface of the limiting rod 95 is sleeved with a second spring 97, and the two ends of the second spring 97 are fixedly connected with the pull plate 96 and the arc-shaped plate 94 respectively. The pull plate 96 can be used to move the position of the limiting rod 95, and the second spring 97 can be used to ensure the stability of the connection between the limiting rod 95 and the arc-shaped plate 94.

[0039] Working principle: when the alkali positive carving additive production reaction kettle is used to produce alkali positive carving additives, first, the cover 10 is opened, raw materials and water are added through the feed port 3 and the water supplementing pipe 4, then the heating shell 1 and the thermometer 5 are used to increase and control the temperature inside the reaction tank 2, the stirring motor 71 of the stirring assembly 7 is started to drive the rotating rod 72 to rotate, so that the stirring blade 73 stirs the reaction materials in the reaction tank 2, improves the reaction speed of the materials in the reaction tank 2, after the production of alkali positive carving additives is completed, the pressure inside the reaction tank 2 is adjusted through the pressure relief valve 6, then the temperature of the reaction materials inside the reaction tank 2 is reduced through the cooling pipe 11, and finally the finished alkali positive carving additives are taken out. When raw materials are added through the feed port 3, first, the reciprocating motor 82 is started to control the rotating rod 83 to drive the moving ring 84 and the blade 85 to rotate forward, at this time the moving ring 84 drives the sliding block 86 to slide on the surface of the fixed rod 87, so that the moving ring 84 moves away from the reciprocating motor 82, after the addition of raw materials is completed, the reciprocating motor 82 is controlled to reverse, at this time the rotating rod 83 drives the moving ring 84 to reverse, and under the action of the first spring 88 and the reverse rotation, the moving ring 84 moves close to the reciprocating motor 82, completing the cleaning of the surface of the rotating rod 83. The reciprocating motor 82 can be installed on the reaction tank 2 through the installation block 81, and the inside of the feed port 3 can be dredged through the dredging device 8 when raw materials are added through the feed port 3, so as to as far as possible ensure that the process of adding raw materials will not cause the feed port 3 to be blocked, and ensure the progress of adding raw materials.

[0040] When it is necessary to add raw materials, first pull the pull plate 96 to drive the limit rod 95 to slide on the inner wall of the curved plate 94, so that the limit rod 95 moves away from the positioning block 93, releasing the restriction on the position of the cover 10, and then rotate the cover 10 so that the rotating shaft 92 rotates on the inner wall of the connecting plate 91. At this time, the cover 10 releases the closure of the feed port 3, loosens the pull plate 96, and under the action of the elastic force of the second spring 97, the pull plate 96 moves close to the curved plate 94. When the raw materials are added, the pull plate 96 is pulled away from the curved plate 94, and the cover 10 is rotated to close Move close to the positioning block 93 and release the pull plate 96. At this time, under the action of the elastic force of the second spring 97, the limiting rod 95 moves close to the positioning block 93 to limit the position of the cover 10, thereby achieving the closure of the feed port 3. By setting the connecting device 9, it is convenient to use the cover 10 to close the feed port 3 or release the cover 10 from closing the feed port 3. By setting the positioning block 93, it can play a positioning role when using the cover 10 to close the feed port 3. At the same time, the position of the cover 10 can be limited by the positioning block 93 and the limiting rod 95.
