Description

TECHNICAL FIELD

[0001] The utility model relates to thin film detection technical field especially relates to a heat shrinkable film packaging detection device. BACKGROUND

[0002] Heat shrinkable packaging is to use plastic film with heat shrinkage performance to wrap and heat seal the material, and then make the packaging article pass through a heating chamber to make the film shrink tightly on the article at a certain temperature to form a neat and beautiful packaging product. Shrink packaging is one of the more advanced packaging methods on the international market. It is to wrap the product or packaging piece with shrink film, and then heat to make the packaging material shrink and tightly wrap the product or packaging piece to fully display the appearance of the article and improve the sales performance to increase the beauty and value. At the same time, the packaged article can be sealed, moisture-proof, and pollution-proof, and can protect the goods from external impact, with certain buffering property. Especially when packaging glass products, it can prevent glass from flying when broken. In addition, it can reduce the possibility of product being damaged or stolen. When the shrink film shrinks, it generates a certain pulling force, so it can tightly wrap a group of articles to be packaged.

[0003] At present, heat shrinkable film needs to be detected before use to prevent damage and subsequent packaging problems. For example, the utility model patent with the authorization announcement number CN221367895U discloses a film detection device of heat shrinkable packaging machine. The device unwinds the film through the unwinding assembly, and then detects the film through the detection assembly. When the film is detected to be damaged, the worker can cut or repair the damaged film according to the alarm, which can improve the working efficiency of the packaging machine, has simple structure and is convenient to use, and meets the existing use requirement. However, the inventor finds that the device has certain deficiencies. When the width of the film is less than the width of the reaction plate, the wind will blow to the reaction plate, and then the alarm will issue an alarm, resulting in the failure of the damage detection function. Moreover, the device is not convenient for directly repairing the damaged film, and the practicability and applicability of the device are not high. Therefore, we design a heat shrinkable film packaging detection device. UTILITY MODEL CONTENT
