Packaging belt production line

Abstract

The invention provides a packaging belt production line and belongs to the field of packaging belt production. The packaging belt production line comprises a stirring funnel, a material melting and stirring cylinder, a drying device, a knurling device and a coiling device. The stirring funnel is provided with a material inlet. A screening funnel is arranged at the material inlet and connected withthe output end of a vibrator. A material mixing auger is further arranged in the stirring funnel. The lower side of the stirring funnel communicates with an inlet of the material melting and stirringcylinder. A stirring auger is arranged in the material melting and stirring cylinder. Constant temperature heating rods are further arranged on the inner wall of the material melting and stirring cylinder. The outlet end of the material melting and stirring cylinder is provided with a melt filtering device. An extrusion head is arranged between an outlet of the melt filtering device and a water cooling pool. The packaging belt production line can improve production efficiency, improve the yield of packaging belts and lower the investment cost of the production line.

Description

technical field [0001] The invention relates to the field of packaging tape production, in particular to a packaging tape production line. Background technique [0002] At present, the production efficiency of the packaging tape production line is relatively low, and the speed connection in the production process is not good. [0003] The production efficiency of the packaging tape production line is greatly affected by the melting process, and the specific melting temperature must be controlled at a constant temperature to ensure the strength and quality of the packaging tape. Therefore, the production efficiency cannot be improved by increasing the temperature and reducing the viscosity of the molten raw material. [0004] On the other hand, in the drying process, the existing drying device cannot eliminate the internal stress, and often requires a separate stretch forming machine after the drying device to perform an additional process. [0005] The embossing and coiling...

[0002] At present, the production efficiency of the packaging tape production line is relatively low, and the speed connection in the production process is not good

[0003] The production efficiency of the packaging tape production line is greatly affected by the melting process, and the specific melting temperature must be controlled at a constant temperature to ensure the strength and quality of the packaging tape. Therefore, the production efficiency cannot be improved by increasing the temperature and reducing the viscosity of the molten raw material

[0004] On the other hand, in the drying process, the existing drying device cannot eliminate the internal stress, and often requires a separate stretch forming machine after the drying device for additional processes

[0005] The embossing and coiling devices of the entire packaging tape production line need to be replaced due to the need to adapt to different types of packaging tapes. When replacing the embossing and coiling devices on the existing production line, the entire set is generally replaced, or a dedicated Production line, high cost, not good for production rhythm
