Description

Technical Field

[0001] The invention relates to packaging technology, in particular to a rear transverse sealing ironing block mechanism and a transverse sealing device which integrates an easy-tear knife and an ironing block. Background Art

[0002] At present, multi-row filling and packaging machines for strip packs usually cut out easy-tear notches at the seal to facilitate the smooth tearing of the strip packs. There are usually two methods in the existing technology: the first is that the easy-tear notches are divided into horizontal and vertical tear notches. These two easy-tear notches are cut out at different stations. Each tear notch has an independent drive, but the positions of the easy-tear notches deviate due to the order in which they are cut out at different stations. The second is that the horizontal and vertical tear notches are cut out at the same time. At the station below the horizontal seal, the cut position will deviate from the relative position of the horizontal seal, which is mainly affected by factors such as bag length, mechanical position of the cutter, and tension of the film roll.

[0003] Therefore, the two existing methods cannot ensure that the theoretical relative positions of the easy-tear edge and the transverse seal are consistent, and position deviations will always occur, making it difficult to ensure the stability of quality. Summary of the invention
