Disposable lunch box forming device and disposable lunch box processing energy-saving method

Abstract

The invention discloses a disposable lunch box forming device. The device comprises a machine frame, a heating section and a forming section, and further comprises a preheating section, an air supplypiece, a hot air collecting piece and a draught fan, the heating section and the forming section are sequentially arranged on the machine frame, and the preheating section is mounted at the front endof the heating section. The air supply piece and the hot air collecting piece are arranged at the two sides of the upper portion of a blister mold of the forming section, the hot air collecting pieceis communicated to an air inlet of the draught fan through an air pipe, an air outlet of the draught fan is communicated to inlet air of the preheating section through an air pipe, and outlet air of the preheating section is communicated to the air supply piece through an air pipe. According to the disposable lunch box forming device and the disposable lunch box processing energy-saving method, hot air of the forming section can be recycled to preheat sheets entering the heating section, energy is saved, and the equipment operation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of lunch box processing, in particular to a disposable lunch box forming device and an energy-saving method for disposable lunch box processing. Background technique [0002] Disposable fast food boxes have changed from foam lunch boxes to environmentally friendly lunch boxes. The original foam lunch boxes were eliminated due to their inability to withstand high temperatures and the damage to the environment caused by the production process. Plastic lunch boxes, paper lunch boxes, wooden lunch boxes, and degradable lunch boxes have been replaced. Among them, plastic has the characteristics of low toxicity, high melting point, strong plasticity, easy production and relatively low cost, so it has become the mainstream material for manufacturing disposable fast food boxes. [0003] The specific production method of the plastic lunch box is: use polystyrene resin as raw material, heat and melt at high temperatur...

AI Technical Summary

Problems solved by technology

However, the energy waste of the existing plastic forming equipment is relatively serious, the heating power is large, and the high-temperature formed sheet needs to be blown and cooled after the mold is formed in the forming section, which is convenient for mold release and solidification, and at the same time causes a large number of heat loss
