Description

TECHNICAL FIELD

[0001] The utility model relates to paper cup technical field, specifically, relate to a kind of polylactic acid film-coated paper cup drying machine. BACKGROUND

[0002] Traditional paper cup is usually made of polyethylene (PE) film-coated material, which is non-degradable and accumulates in landfills, cannot be recycled and causes long-term pollution to the environment. Therefore, a paper cup using polylactic acid (PLA) as the film-coated material is developed, which has the characteristics of environmental protection and biodegradability. PLA is a new biodegradable material made from starch raw materials extracted from renewable plant resources such as corn, and can be completely degraded into carbon dioxide and water in the natural environment through fermentation and polymerization reaction, without causing pollution to the environment. After film-coating, slitting, printing, die-cutting and other processes, the paper cup enters the forming stage. After the cup body is formed, it needs to be dried by a drying machine to completely cure the PLA film-coated material, improve the waterproof performance and prevent the paper cup from being deformed due to moisture during storage or use.

[0003] During the drying process of polylactic acid film-coated paper cup, there may be some residues such as paper scraps and glue, which are easily attached to the conveying and drying conveyor belt. The residues attached to the conveyor belt may be reattached to the passing paper cup with a certain probability. For example, paper scraps may stick to the surface of the paper cup, causing rough appearance and impurities, and due to the influence of residues, the conveyor belt needs to be maintained and cleaned more frequently. For example, when paper scraps and glue accumulate to a certain extent, it will cause the conveyor belt to run poorly and need to be stopped for cleaning.

Under the action of this continuous slight vibration, the adhesion between the paper scrap on the surface and conveyer belt 1010 gradually weakens, and the paper scrap starts to fall off from the paper cup and scatters on conveyer belt 1010. At the same time, the heating pipe 1012 in the heating cover 1011 starts heating, and the temperature in the heating cover 1011 gradually rises to the set drying temperature. With the continuous operation of the motor that controls the operation of conveyer belt 1010, the conveyer belt 1010 with the paper cup slowly passes through the area of heating cover 1011. In this process, the paper cup is affected by the heat emitted by heating pipe 1012, and the moisture gradually evaporates, realizing drying. At the same time, the vibration generated by vibration assembly 200 makes the paper scrap on the paper cup not easy to adhere to conveyer belt 1010, and keeps the surface of conveyer belt 1010 relatively clean.
