Description

Technical Field

[0001] The utility model relates to the field of film material processing, in particular to a hot stamping frame and processing equipment for recording long hot stamping marks. Background Art

[0002] In the existing film material processing, there are high precision requirements for the cutting accuracy of the film material, so the transmission length of the film material needs to be recorded. In the prior art, there is a method for holographic marking on commodity packaging as described in application number 93110851.9, which discloses a technology for compounding self-adhesive laser holographic marks on commodity packaging or labels for anti-counterfeiting or decoration. The self-adhesive laser holographic mark strips cut into appropriate widths are pasted on printed or unprinted product packaging paper, packaging plastics, various labels or containers through a composite device, and then they are die-cut and formed for product packaging or labels. Its essence is to use the sticking of self-adhesive as a length mark, but the above-mentioned process operation is complicated, and it is easy to cause waste of self-adhesive materials in actual assembly line processing. The accuracy of the self-adhesive as a mark in this application is also limited, which is not conducive to automated production.

[0003] As an appearance treatment process, hot stamping technology used to appear on paper packaging, such as red envelopes, gift bags, envelopes, etc. However, with the improvement of the quality of life, modern people's requirements for appearance have gradually increased, giving rise to the hot stamping technology of soft packaging with PVC, PE, etc. as the main materials. The hot stamping equipment for soft packaging films on the market today can produce a conventional hot stamping effect with a flat appearance and rich colors. By replacing the hot stamping graphic modeling template with a concave and convex mold, the processing effect can achieve a visual texture with a prominent relief. However, the hot stamping components of the hot stamping mechanism currently on the market are fixed on the base. When the hot stamping paper is hot stamped onto the film material, the film material will be transported forward, and the hot stamping paper will also be recycled along the winding path. During this process, the film material and the hot stamping paper will rub against each other, and when the hot stamping paper is not completely separated from the film material, the film material will tear the hot stamping paper.
