AI Technical Summary

Technical Problem

Existing environmentally friendly, high-temperature resistant food packaging film end material recycling devices are not convenient for online automatic control of the recycling end material, cannot automatically monitor the width of the packaging film casting, have inconsistent end material cutting standards, and are easily affected by transparent film, resulting in poor automation effect and low efficiency.

Method used

This environmentally friendly, high-temperature resistant food packaging film scrap recycling device consists of a scrap collection unit, a conveying device, a driving device, and a cutting control unit. It uses an electric heating tube to heat the shrink film, a cutting blade to cut off the edge waste, a lifting and connecting component to monitor the film width, and an electromagnet to control the cutting, thus achieving automated cutting and recycling.

Benefits of technology

It enables online automated material head recycling, reduces manual operation, improves recycling efficiency and standardization, avoids secondary processing and transfer, is suitable for automatic control of transparent films, and simplifies the production line structure.

Abstract

This invention provides an environmentally friendly, high-temperature resistant food packaging film scrap recycling device, relating to the field of plastic recycling technology. It includes a scrap collection component with a conveying device mounted on it. The scrap collection component is used for heat-shrink packaging film. Two driving devices are mounted on the scrap collection component and connected to the conveying device. Two fixed electrical connectors are mounted on the conveying device. The use of lifting electrical connectors in conjunction with the fixed electrical connectors facilitates real-time monitoring of the packaging film width. Furthermore, the electronic control method employed in this structure eliminates the need for laser detection and is unaffected by the transparency of the packaging film, enabling automatic control of the cutting component to cut and recycle the scrap. This addresses the problems of current environmentally friendly, high-temperature resistant food packaging film scrap recycling devices, such as difficulty in online automatic control of scrap recycling, difficulty in automatically monitoring the width of the packaging film, and poor uniformity in scrap cutting standards.
