Description

Technical Field

[0001] The invention relates to packaging equipment technology, in particular to a double-sided embossing heat sealing device. Background Art

[0002] At present, the common sealing patterns of the strip pack multi-row filling and packaging machines are bidirectional grid pattern and plain pattern. Among them, the plain pattern has a large tooth spacing, and the front and rear ironing blocks can automatically mesh with their own teeth; the bidirectional grid pattern has a tooth spacing of about 1mm and a tooth depth of less than 1mm, which cannot be self-engaged by the ironing block's own teeth. Therefore, the current common practice is to use one ironing block as a toothed ironing block and the other as a soft flat surface. When pressed, the soft flat surface is deformed by contact with the toothed surface, and the packaging material is sealed with toothed patterns. Since the ironing block has patterns on one side and a smooth surface on the other side, the sealing patterns of the packaging material are also clear on one side and blurred on the other side, and the clarity of the patterns on both sides cannot be consistent.
