Description

Technical Field

[0001] The utility model relates to the field of granulators, in particular to a plasticizing device of a granulator. Background Art

[0002] A granulator is a molding machine that can make materials into a specific shape. It is widely used in many industries such as chemical, pharmaceutical, food, metallurgy, etc., especially in the field of plastic processing, where the role of granulators is particularly important. The working principle of a granulator is that the raw materials are generally pre-treated and then sent to the plasticizing device of the granulator. In the plasticizing device, the raw materials are subjected to high temperature and mechanical force, gradually changing from a solid state to a molten state. Then, the molten material passes through a specific mold or orifice to form the desired particle shape. Finally, through subsequent treatments such as cooling and solidification, the final particle product is obtained.

[0003] In order to change the solid plastic into a molten state, a granulator plasticizing device is required.

[0004] At present, the plasticizing device of the granulator is usually equipped with a heating mechanism inside the auger to melt the raw materials during the transmission process of the auger. However, in actual use, the raw material particles inside the auger of the granulator may be difficult to heat, resulting in uneven melting and poor plasticizing effect. On the other hand, the melted plastic has a high lifespan. In actual use, the molten plastic will adhere to the inside of the device, which is easy to waste raw materials and mix the new and old raw materials, resulting in the quality of the melted material cannot be guaranteed. Therefore, a granulator plasticizing device is proposed to solve the above problems. Utility Model Content
