Lunch box machine production line

Abstract

The invention provides a lunch box machine production line. The lunch box machine production line comprises a double-screw extrusion molding section and a lunch box forming section, wherein the discharging end of the double-screw extrusion molding section is in butt joint with the feeding end of the lunch box forming section; and a feed hopper is arranged at the front end of a double-screw raw material melting part, the double-screw raw material melting part is communicated with a vacuum circulating water cooling system and a gas circulating filtering system, and a power part and the double-screw raw material melting part are both electrically connected with a power distribution cabinet. According to the lunch box machine production line, the whole production process of a lunch box from granulation melting to lunch box forming is integrally completed, an advanced internal circulation cooling process is adopted, a closed-loop air cooling system is adopted in the melting stage of raw materials, cooling water consumed in the whole cooling process is less, the production and transfer steps are simplified, the energy consumption is reduced, and continuous production is ensured.

Description

technical field [0001] The invention relates to the technical field of production and manufacturing devices of lunch box machines, in particular to a production line of lunch box machines.

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned punching and cutting integrated automatic stacking lunch box forming machine still has obvious defects during use: 1. The front end of the above-mentioned lunch box forming machine uses processed and formed coils, and the coils need to be processed during the processing. Carry out secondary thermoforming, thereby making the lunch box production procedure increase, and improved energy consumption; 2, the above-mentioned device and the lunch box production line in the prior art can't guarantee the quality of the lunch box and the impact on the environment in the production and processing process; Pollution problems, thus increasing the risk of environmental pollution while increasing energy consumption
