AI Technical Summary

Technical Problem

The process temperature of PET foamed sheet is unstable during die cutting, resulting in changes in the physical properties of the material, and the toughness and strength of the material cannot be guaranteed, which increases the scrap rate and manufacturing cost during the box making process.

Method used

A PET foamed sheet box making device is designed, including a sheet preparation production line, a uniform thickness mechanism and a die-cutting mechanism. The uniform thickness mechanism controls the uniform thickness of the sheet through a plurality of synchronously rotating first rollers, and the die-cutting mechanism provides a heater in the first box to ensure that the temperature of the sheet is stable during indentation.

Benefits of technology

Through the design of uniform thickness mechanism and die-cutting mechanism, the thickness of the PET foamed sheet is uniform and the temperature is stable, the toughness and strength of the material are improved, the scrap rate and manufacturing cost are reduced, and the quality of the packaging box is ensured.

Abstract

The invention relates to the technical field of foamed sheet box manufacturing, and provides a PET foamed sheet box manufacturing device which comprises a sheet manufacturing production line, a thickness uniformizing mechanism and a die cutting mechanism. The sheet preparation production line is used for preparing a first sheet, the thickness uniformizing mechanism comprises a plurality of first roller bodies, the distances between every two adjacent first roller bodies are equal, and the first roller bodies rotate synchronously; the die cutting mechanism comprises a first box body, a die cutting die, a first heater and a cutting knife, the die cutting die is arranged in the first box body, the first heater is arranged in the die cutting die, the die cutting die is used for carrying out indentation on the first sheet, and the cutting knife is arranged outside the first box body and used for cutting the first sheet along the indentation. According to the PET foaming sheet box making device, when the first sheet is subjected to indentation, temperature loss of the first sheet can be avoided, the stability of the physical property of the first sheet is guaranteed, the toughness and strength of the first sheet are improved, and then the quality of a formed packaging box is guaranteed.
