Description

Technical Field

[0001] This utility model relates to the field of plastic bag manufacturing technology, specifically a zipper embossing device for plastic bag manufacturing. Background Technology

[0002] Chinese patent document CN217169753U discloses an embossing device for processing plastic products. It proposes an embossing method where a sheet material is placed between upper and lower molds, and pressure is applied to change the material thickness. The material outside the embossed portion fills the convex and concave areas of the mold cavity with undulating fine lines, resulting in embossed bumps, lettering, or patterns on the workpiece surface. Existing embossing devices for processing plastic products cannot quickly replace the embossing mold block, reducing embossing efficiency. The solution is to design an embossing device for processing plastic products where pulling a lever detaches a clamping plate from the embossing mold. Once the embossing mold loses its clamping force, it can be easily replaced. After replacement, releasing the lever causes the spring force to tighten the clamping plate, thus improving the efficiency of mold replacement.

[0003] The above-mentioned solutions and existing technologies, when using zipper embossing devices to emboss plastic bags, cannot provide auxiliary positioning for the plastic products. This can lead to displacement of the plastic bags during conveyor belt transport, resulting in embossing failure and increasing the cost of plastic bag embossing. This does not meet the actual usage requirements.
