Description

Technical Field

[0001] This utility model belongs to the field of plastic packaging bag production technology, and in particular relates to an embossing device for plastic packaging bag production. Background Technology

[0002] Embossing is a crucial step in packaging production, enhancing both the aesthetics and functionality of products. By pressing specific textures onto the surface of the plastic film, not only is the visual appeal of the packaging improved, but its physical properties, such as slip resistance and tear resistance, are also enhanced. Embossing of plastic packaging bags is typically achieved through hot or cold pressing. Hot pressing involves heating the film to its softening temperature (approximately 120-180℃) and transferring the pattern under pressure using steel or copper rollers with raised or recessed textures. Cold pressing is suitable for temperature-sensitive materials, relying on high pressure (5-20 MPa) to induce plastic deformation.

[0003] Comparing with Chinese Patent No. CN213006816U, a packaging bag embossing machine is disclosed, including an embossing machine body. A motor box is fixedly connected to one side of the embossing machine body, and a feed inlet is provided on the front side of the embossing machine body. A base plate is fixedly connected to the bottom of the embossing machine body. A first support plate is fixedly connected to one side of the top of the base plate, and a second support plate is fixedly connected to the other side of the top of the base plate. A first roll material column is fixedly connected to the upper end of the first support plate, and a second roll material column is fixedly connected to the lower end of the first support plate. Several guide columns are fixedly connected to the inner side of the second support plate. Through the embossing machine body, motor box, feed inlet, first roll material column, second roll material column, pressure roller, ball bearing, rotating shaft, embossing roller, and motor, material is placed on the first and second roll material columns, and the embossing roller embosses the material, making it convenient for users.

[0004] However, the fixed spacing between the aforementioned patented pressing roller and embossing roller cannot adapt to plastic packaging bags of different thicknesses or adjust the rolling pressure, which greatly reduces the adaptability of plastic packaging bag embossing production. Therefore, a new type of equipment needs to be designed. Utility Model Content
