Description

Technical Field

[0001] The utility model relates to the technical field of biodegradable plastics, and more particularly to a heating device for biodegradable plastics. Background Art

[0002] In existing technologies, traditional heating equipment and methods often fail to provide uniform heat distribution, resulting in uneven heating of the plastic during the heating process. This uneven heating can lead to temperature differences between the inside and outside of the plastic, thus affecting the melting and processing quality of the plastic. Uneven heating can also cause local overheating or burning of the plastic, further reducing heating efficiency and product quality.

[0003] Secondly, the existing technology usually requires heating the entire plastic, which takes a long time. Since the volume and shape of the plastic may be large, heating the entire plastic will result in a longer heating time, thereby reducing production efficiency. In addition, heating the entire plastic may also lead to energy waste because it is necessary to heat the entire plastic instead of just the part that needs to be melted.

[0004] In addition, the existing technology often lacks the function of crushing the plastic before heating. Crushing is one of the important steps in plastic processing. It can break down the plastic into smaller particles, thereby improving the efficiency of heating and melting. However, the heating equipment in the existing technology usually does not have a crushing function and requires additional equipment and steps for crushing, which further increases production costs and time.
