Technical Field
[0001] This utility model relates to the field of packaging machine technology, specifically a reciprocating high-speed automatic heat shrink packaging machine. Background Technology
[0002] The reciprocating high-speed automatic heat shrink packaging machine is a highly efficient packaging equipment used for packaging various types of products. It wraps the product with heat shrink film, which is then heated and shrunk, causing the film to adhere tightly to the product surface, thus securing and protecting the product.
[0003] After packaging the product, the packaging machine sends it into the shrink chamber for heat shrinking. Existing shrink chambers typically include a heating resistor and a fan. The fan, fixed to the wall, blows hot air onto the conveyor belt. As the product passes over the fan, the film heats up and shrinks, adhering tightly to the product surface. However, for longer and wider products, due to their large area, the fan can only heat one section of the product surface, resulting in uneven heating and poor shrinkage. To address these issues, this invention provides a reciprocating high-speed automatic heat shrink packaging machine. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a reciprocating high-speed automatic heat shrink packaging machine, which solves the problem that for some long and wide products, due to their large area, the fan can only heat one section of the product surface, while other areas cannot be fully heated, resulting in uneven heating and poor shrinkage effect.
