[0028] The working principle of this utility model:

[0029] Refer to the instruction manual Figure 1-Figure 5The utility model is provided with a mixing kettle 1, a heating pipe 2, a heating plate 3, a heating ball 4, a liquid infusion pipe 5, a supporting head 6, a stirring assembly 7 and a scraper 8, so as to transport the film raw material into the mixing kettle 1, and transport the heat-conducting oil to the heating ball 4 through the liquid infusion pipe 5. After the heat-conducting oil enters the heating ball 4, it fills the heating ball 4. Then, the heat-conducting oil inside the heating ball 4 moves upward and enters the heating pipe 2 and the heating plate 3. After the heat-conducting oil fills the heating pipe 2 and the heating plate 3, it is transported from the top of the heating pipe 2 to the outside of the mixing kettle 1 for circulation, so that the heating pipe 2, the heating plate 3 and the heating ball 4 inside the mixing kettle 1 heat the raw material, the heating pipe 2 heats the center of the interior of the mixing kettle 1, and the heating plate 3 extends from the outer wall of the heating pipe 2 to heat the air inside the mixing kettle 1 The heating process is carried out between the heating tubes 2 and the heating ball 4, and the heating ball 4 heats the raw materials at the bottom of the mixing kettle 1 at the bottom of the heating tube 2. At the same time, the support head 6 is driven to rotate, and the stirring component 7 rotates with the support head 6. The two stirring components 7 perform a circular rotation on the outside of the heating tube 2. The stirring component 7 can effectively drive the raw materials to rotate inside the mixing kettle 1, so that the raw materials inside the mixing kettle 1 quickly contact and move with the surfaces of the heating tube 2, the heating plate 3 and the heating ball 4, which can effectively improve the heating effect of the raw materials inside the mixing kettle 1 during the mixing and stirring process, and ensure the dissolution and mixing effect of the raw materials inside the mixing kettle 1; the scraper 8 rotates with the stirring component 7, and the scraper 8 scrapes the inner wall of the mixing kettle 1, which can effectively avoid the raw materials from remaining inside the mixing kettle 1;

[0030] The stirring rod 12 in the stirring assembly 7 rotates in a circular motion around the heating tube 2, the heating plate 3 and the heating ball 4 with the support head 6, which can effectively improve the contact movement effect between the raw materials in the mixing kettle 1 and the surfaces of the heating tube 2, the heating plate 3 and the heating ball 4, so that the heating treatment effect of the raw materials in the mixing kettle 1 is better; the first stirring bars 13 are obliquely symmetrically arranged on the surface of the stirring rod 12, and the first stirring bars 13 rotate in a circular motion around the heating tube 2, the heating plate 3 and the heating ball 4 with the stirring rod 12, which can further enhance the movement diversity of the raw materials in the mixing kettle 1, effectively improve the mixing treatment effect of the raw materials, and thus improve the raw materials. The contact effect between the raw materials and the heating component is improved, thereby improving the heating treatment effect of the raw materials during the mixing process, thereby improving the dissolution and mixing uniformity of the film raw materials; the design of the heating plate 3 extending between the two adjacent first stirring bars 13 allows the heating plate 3 to be inserted into the inner side of the stirring component 7, and the heating plate 3 will not affect the stirring and mixing work of the stirring component 7 on the raw materials. The stirring component 7 can directly stir and blend the raw materials outside the heating plate 3, so that the raw materials outside the heating plate 3 can quickly move and switch positions under the stirring action of the stirring component 7, which can further improve the heating and mixing treatment effect of the raw materials inside the mixing kettle 1;

[0031] The heat transfer oil is first transported to the third liquid storage chamber 16 of the heating ball 4 through the infusion pipe 5. After the heat transfer oil fills the third liquid storage chamber 16, the heat transfer oil enters the second liquid storage chamber 15 of the heating plate 3 through the first liquid storage chamber 14 of the heating tube 2. After the heat transfer oil fills the second liquid storage chamber 15, it continues to be transported upward along the first liquid storage chamber 14. Finally, the heat transfer oil is transported to the outside of the mixing kettle 1 through the heating tube 2 for recycling.
