DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In this structure, the number of feeding pipes 3 is not mandatory here. Various plastic raw materials are added into the tank body 1 through the feeding pipe 3, and the motor 4 is started. At this time, the rotating shaft 7 rotates. After the rotating shaft 7 rotates, the first mixing rod 9 and the mixing rod will rotate. After the various materials enter the interior of the top cover 2, they will enter the tank body 1 at the discharge port 10. The first mixing rod 9 can rotate in the discharge port 10, and can provide a mixing effect for the materials at the discharge port 10, so that the various materials can be preliminarily mixed before entering the interior of the tank body 1, and then the materials in the tank body 1 are deeply mixed by the mixing rod, and the mixing efficiency is high, thereby improving the plastic production efficiency.

[0024] When the material just enters the top cover 2, the present structure lacks a mixing structure for the material, which will reduce the mixing efficiency of the present structure. A second mixing rod 11 is provided on the top of the rotating shaft 7, and a baffle plate 12 located below the second mixing rod 11 is fixedly provided on the inner wall of the top cover 2. When the rotating shaft 7 rotates, the second mixing rod 11 will rotate. When the material just enters the top cover 2, the present structure can provide a mixing structure for the material, which can improve the mixing efficiency of the present structure. Through the baffle plate 12, the material can enter the interior of the conical cylinder 8 more smoothly.

[0025] When the conical cylinder 8 is damaged, it is necessary to disassemble the conical cylinder 8. A positioning block 15 located on the inner wall of the top cover 2 is fixedly provided below the baffle plate 12. An annular sheet is provided at the top of the conical cylinder 8. The annular sheet is fixed to the lower end of the positioning block 15 by screws. The baffle plate 12 and the positioning block 15 are both annular structures. When the conical cylinder 8 needs to be disassembled, the screws on the annular sheet can be loosened. The structure is simple and the operation is convenient.

[0026] In this structure, an anti-wear sleeve is fixedly provided on the outer wall of the scraper rod 13. The anti-wear sleeve can be a rubber sleeve, which can avoid hard collision between the scraper rod 13 and the tapered tube 8 and improve the service life of the scraper rod 13 and the tapered tube 8.
