Abstract
Description
Technical Field
[0001] The utility model relates to the field of packaging equipment, and relates to a film-covering temperature control system for plant beverages. Background Art
[0002] Bottled functional plant-based beverages require a high degree of sealing, so they are often coated with heat shrink film to improve the seal between the cap and the bottle. The laminating process typically involves conveying the heat-shrink filmed product via a conveyor line into a heating chamber, where steam heat shrinks the film until it adheres to the bottle.
[0003] However, the temperature monitoring device of the existing film packaging machine is usually set at the steam generating end. The steam generating device heats the steam to the set temperature and then transports it to the heating chamber. The two ends of the heating chamber are provided with an inlet and outlet for the packaging bottles to pass through. The steam reaching the heating chamber is easily affected by the external environment and the temperature drops. Therefore, it is difficult to ensure that the temperature of the steam transported to the heating chamber meets the shrinkage requirements of the heat shrinkable film; problems such as uneven film shrinkage and uneven film layer on the bottle surface are prone to occur, affecting the product qualification rate.
[0004] In addition, the inlets and outlets at both ends of the heating chamber are usually set according to the largest size of the product packaging bottle. When small-sized packaging bottles pass through the inlets and outlets, a large amount of steam will overflow from the remaining space of the inlets and outlets, affecting the temperature stability of the heating chamber and causing waste.
