Description

Technical Field

[0001] The utility model relates to the technical field of heat sealing devices, in particular to a fast film-changing reciprocating heat sealing device. Background Art

[0002] The working mode of the heat sealing device is to heat the material at the sealing point to make it reach a viscous flow state and then pressurize it to make it sticky and seal. The heat sealing methods can be specifically divided into: ordinary heat pressure sealing, melting sealing, pulse sealing, ultrasonic sealing, high-frequency heat sealing and induction heat sealing. Different heat sealing methods are targeted at different film characteristics. The most commonly used heat sealing method is ordinary heat pressure sealing. Ordinary heat pressure sealing has several types, including flat heat sealing, disc heat sealing, belt heat sealing and sliding clamp sealing. Flat heat sealing is the most popular.

[0003] Referring to the existing patent publication number: CN218641232U, a heat sealing device of a packaging machine includes a cover plate, a support plate, a bottom plate, a power source, a transmission mechanism, a heat sealing upper mold, a heat sealing lower mold and a slide rail. The cover plate is connected to the bottom plate through the support plate, the power source is arranged on the cover plate, the heat sealing lower mold is arranged on the bottom plate, the power source is connected to the heat sealing upper mold through the transmission mechanism, a slider is arranged at the lower end of the bottom plate, and the slider is slidably arranged on the slide rail. The setting of the connecting rod assembly increases the fulcrum, so that the material is evenly stressed and the consistency of the heat sealing effect is ensured. The axially symmetrically arranged connecting rod assembly as a whole can offset the lateral forces acting on the heat sealing upper mold, so that the heat sealing upper mold can move up and down stably.

[0004] However, in actual use, the existing heat sealing device will cause the sealing film to be exhausted due to long-term work when the product is heat-sealed. Therefore, the film roll needs to be disassembled and assembled during a certain period of time. However, the existing film roll disassembly and assembly mechanism is relatively cumbersome, which is not conducive to the work and has low efficiency, affecting the work progress.
