Description

Technical Field

[0001] The utility model relates to the technical field of modified plastic pellet processing, in particular to a modified plastic pellet hot melting device. Background Art

[0002] Modified plastic pellets are a type of modified plastic raw material, usually in the form of particles, and are used to manufacture various plastic products. Modified plastic pellets can improve the performance of the original plastic by adding different additives or fillers, such as improving strength, toughness, heat resistance, flame retardancy, and aging resistance.

[0003] Thermal melting of modified plastic particles refers to heating the modified plastic particles to a molten state at a certain temperature, and then cooling and solidifying them to obtain the desired plastic products.

[0004] This process usually includes the following steps:

[0005] Preparation of modified plastic particles: Modified plastic particles are obtained by modifying the basic plastic by adding various additives or fillers. These additives may include reinforcing materials, toughening agents, flame retardants, anti-aging agents, etc. The modified plastic particles have better physical and chemical properties;

[0006] Thermal melting: The modified plastic particles are placed in a heated mold and the heat from the mold is used to melt the plastic particles. The temperature needs to be well controlled during this process to ensure that the plastic particles can be completely melted and not decomposed;

[0007] Shaping: The molten plastic will fill the various parts of the mold to form a plastic product that matches the shape of the mold;

[0008] Cooling and solidification: The filled mold is cooled to solidify the molten plastic into a final plastic product.

[0009] At present, when performing heat melting on modified plastic pellets, most molds have a single structure, and additional heating elements need to be added to the mold to meet the heat melting processing of the modified plastic pellets in the mold. However, after the processing is completed, the mold and the heating element are not easy to disassemble, resulting in the need for tools to separate them when cleaning the mold. In addition, different molds have different shapes of products formed after heat melting. If quick assembly cannot be achieved, it is relatively cumbersome to replace the product mold.
