Description

Technical Field

[0001] The utility model relates to the technical field of biodegradable film production, in particular to a fully biodegradable film stretching device. Background Art

[0002] Plastic film products are the most common packaging materials in daily life. Plastic film is a necessary means to increase agricultural production and income. While traditional plastic film products bring convenience to people and increase agricultural production and income, they also cause great harm to the environment due to their non-degradable characteristics. In recent years, polylactic acid (PLA), polybutylene succinate (PBS), polybutylene terephthalate-adipate (PBAT), etc., as well as fully biodegradable green and environmentally friendly products modified by adding starch, have been introduced one after another to replace traditional non-degradable plastics.

[0003] After searching, the patent number is CN117162468A, and the specific name is a fully biodegradable film stretching device, which includes a base, a stretching box, a heating roller and a heat sink. The base is in a strip-shaped structure as a whole, and the stretching box is installed in the middle of the upper surface of the base; heating brackets and heat sinks are relatively installed on the base on both sides of the stretching box, and the two ends of the heating roller are installed on the opposite heating brackets, and the heat sink is arranged between the opposite heat sinks; the interior of the stretching box is hollow, and the stretching box is provided with stretching material ports on both sides of the stretching box facing the heating bracket and the heat sink; a stretching roller is installed inside the stretching box, and the stretching roller moves in the vertical direction along the wall of the stretching box to adjust the position;

[0004] Before traditional fully biodegradable film stretching equipment stretches the film, the film may be contaminated from various sources. For example, during the production, transportation, storage and processing of the film, it may be exposed to dust and debris in various environments, causing contamination on its surface. These pollutants may affect its performance and processing process. When the stretching equipment stretches the film with dust and debris attached, the dust and debris may cause stress concentration during the stretching process, making the film prone to breakage or abnormal deformation in these areas. Dust and debris may change the adhesion of the film surface, making it impossible to effectively contact the film during the stretching process, resulting in unstable stretching and affecting the quality of the product after stretching.
