Description

Technical Field

[0001] The utility model relates to the technical field of steam shrinkage furnaces, in particular to an exhaust adjustment structure for a steam shrinkage furnace. Background Art

[0002] A steam shrink oven is a device that uses steam to shrink packaging materials and adhere them to the surface of the product. It is usually used for post-packaging processing of various container products, such as beverage bottles, food packaging, cosmetics packaging, etc.

[0003] A Chinese patent (authorization announcement number: CN218641238U, authorization announcement date: 2023.03.17) proposes an exhaust adjustment structure for a steam shrinkage furnace. The patent transports the product from the entrance to the exit of the shrinkage channel part through a conveyor belt. Before spraying steam on the beverage bottles, the front and rear adjustment components are used to adjust and control: the spacing between the exhaust pipes on the front and rear adjustment rods is adjusted, so that beverage bottles of different specifications can be jet-shrinked. Then, the angle adjustment component is used to tilt the exhaust pipe on the adjustment rod, thereby increasing the vertical length of the air hole on the exhaust pipe. The exhaust pipes on the front and rear sides are adjusted symmetrically to ensure consistent expansion and contraction effects, and labels with larger vertical lengths can be expanded and packaged.

[0004] During use, existing steam shrinking furnaces will cause steam to be continuously emitted from the processing area, which increases the risk of workers and maintenance personnel being scalded by the overflowing steam. At the same time, the existing method of fixing containers is to install multiple fixing seats on the conveyor belt to send containers of certain specifications for heating. This fixing method is not suitable for processing containers of different sizes and requires time and effort to adjust. Therefore, we propose an exhaust adjustment structure for a steam shrinking furnace. Utility Model Content
