Description

Technical Field

[0001] The utility model relates to the field of heat shrink film packaging machines, in particular to a heat shrink film packaging machine capable of automatically bagging and sealing. Background Art

[0002] Shrink film is used to wrap the product or package. After heating, the shrink film shrinks and wraps the product or package tightly, fully displaying the appearance of the item, improving the product's sales, and increasing its beauty and value. The items packaged by the heat shrink machine can be sealed, moisture-proof, and pollution-proof, and protect the goods from external impacts. It has a certain cushioning effect, especially when packaging fragile items, it can prevent the items from flying when the container is broken.

[0003] In the prior art, a Chinese patent document with application number CN202223353658.X records a heat shrink film packaging machine. The patent completes the sealing and cutting of the heat shrink film through the mutual cooperation of an electric push rod, a spring rod, a cutter and an electric heating block, and with the assistance of a servo motor and a transmission component. There is no need to pre-package the product, thereby greatly reducing the time required for packaging and improving packaging efficiency. The heat shrink film is cooled down through the mutual cooperation of an air pump, a second connecting pipe and a second air outlet pipe, so that the texture of the heat shrink film becomes hard again, thereby preventing the heat shrink film from being wrinkled or damaged when the product is taken, and ensuring the beauty of the product packaging. When an existing heat shrink film packaging machine is in use, due to the open through slots on both sides of the oven, the heat generated by the heating group inside the oven is easy to flow out along the through slots, causing heat loss, affecting the packaging efficiency, and bringing certain adverse effects to people's use process. For this reason, we propose a heat shrink film packaging machine that can automatically bag and seal. Utility Model Content
