Description

Technical Field

[0001] This utility model belongs to the field of plastic processing material conveying technology, and in particular relates to a material conveying device for plastic production. Background Technology

[0002] Plastic products are typically manufactured using methods such as injection molding, blow molding, and extrusion. In the production of plastic products, it is necessary to first mix and melt the corresponding plastic granules according to the product's color, material, and other requirements. Then, the molten plastic is conveyed to the mold via a conveying device for product production. However, mixing the plastic granules before heating them presents a problem: the granules cannot be fully mixed and melted, resulting in color deviations in the molded products. Furthermore, before mixing multiple plastics, the specific gravity of each plastic needs to be determined according to the product requirements. This process reduces production efficiency.

[0003] To address these issues, we provide a material conveying device for plastic production. Utility Model Content

[0004] The purpose of this invention is to provide a material conveying device for plastic production. By setting a mixing component at the inlet of the conveying component, different plastic particles are first heated and melted by a heater in the mixing component, and then the molten plastic is mixed and stirred by the auger stirring blades on the stirring shaft. The material discharge component is set above the funnel cover of the mixing component, and the plastic particles are divided by the isolation plate inside the discharge pipe wall of the material discharge component. The corresponding proportion of plastic is discharged by pulling out the pull plate as needed. This solves the problems of uneven melting of plastic due to plastic mixing and heating, and low product production efficiency due to plastic proportioning process in existing plastic mixing and heating methods.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
