Description

Technical Field

[0001] The invention relates to the field of packaging bag processing, in particular to a heat sealing device for a degradable packaging bag. Background Art

[0002] With the increase of environmental awareness, biodegradable packaging bags are increasingly widely used in the market due to their environmentally friendly characteristics. During the production process of such packaging bags, the raw film is usually stored on a reel in a wound form to facilitate subsequent transportation and storage management. However, in the traditional production and processing process, the film unrolled from the reel needs to be unfolded, accurately cut with the assistance of manual or simple machinery, and finally sealed by independent heat sealing equipment. This series of steps mostly relies on manual or semi-automatic equipment to complete, which has problems such as low efficiency, high labor costs and difficulty in ensuring production accuracy.

[0003] Specifically, most existing heat-sealing devices only focus on the heat-sealing process itself, lacking effective integration with the previous film unfolding and cutting processes, resulting in a low degree of automation in the entire production line, affecting production efficiency and consistency in product quality. In addition, more manual intervention also increases the complexity of operations and the risk of errors, which is not conducive to the needs of large-scale industrial production. Therefore, the market urgently needs a heat-sealing device for degradable packaging bags that can automatically complete film unfolding, precise cutting and efficient heat sealing, in order to improve production efficiency, reduce costs, and ensure product quality.
