Abstract

The utility model relates to the technical field of packaging equipment, in particular to heat-sealing packaging equipment which is provided with a conveying mechanism and a film covering heat shrinkage mechanism, a negative pressure generating mechanism is arranged in the conveying mechanism, negative pressure can be generated between a heat shrinkage film and a bottom film, meanwhile, a product is heat-sealed between the heat shrinkage film and the bottom film through the high temperature of a heating pipe, and therefore the packaging efficiency is improved. The automation degree is high, heat sealing efficiency and quality are improved, and the requirements of the modern packaging industry are met; in addition, the film covering thermal shrinkage mechanism comprises a movable support, a lifting driving assembly, an unwinding assembly and a grabbing assembly, and the grabbing assembly pulls out the thermal shrinkage film in the unwinding assembly and covers the lower portion of the movable support. The lifting driving assembly drives the movable support to move downwards and enables the pulled-out heat shrinkage film to cover the upper end of the product so that subsequent negative pressure heat sealing packaging can be conveniently carried out, the packaging efficiency is improved, and the device is suitable for various product sizes. And the heat shrinkage film is pulled out through the grabbing assembly, the phenomena of jamming and deviation are avoided, and the heat sealing packaging quality is improved.
