Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging bag production, in particular to a packaging bag cold cutting device. Background Art
[0002] Packaging bags refer to bags used to package various items, making it easy to transport and store goods during the production and circulation process. They are widely used in daily life and industrial production. With the development of science and technology, mechanized bag-making machines have gradually become necessary products in various industries. When dividing them into individual bags, cutting machines are needed.
[0003] During the production of packaging bags, the raw material is heat-pressed to form a single double-layer film. The operator then uses a cutter to cut the film lengthwise according to the bag's width, then cuts it widthwise, ultimately creating several bags. Existing bag cutting devices are prone to misalignment during the cutting process, resulting in poor cutting efficiency. In existing technology, bags are often cut manually using a blade, which can only cut the bag into two sections at a time. This not only reduces cutting efficiency but also results in uneven cut ends, hindering usability.
[0004] Moreover, when the packaging bags are cut, the cutting knife generates heat, and the heat on the cutting knife will be transferred to the packaging bags. The heat on the packaging bags can easily cause the packaging bags to shrink, thus affecting the production quality of the packaging bags. Summary of the Invention
