Technical Problem

由于凸字软胶码在热烫时仅凸出字符的部分会与真空包装袋接触，真空包装袋围绕凸出字符外围的部分容易发生漏气，进而影响真空包装袋的封口效果

Benefits of technology

[0021] Understandably, during the actual operation of the vacuum sealing device, the structure of the characters arranged side-by-side within the mounting groove and at least partially protruding from the groove ensures the clarity and stability of the heat-sealed characters. The placement of the heat-pressing strip on at least one side of the mounting groove further enhances the sealing performance, ensuring that the vacuum packaging bag maintains good vacuum and preservation effects while marking the characters. Furthermore, the roller-shaped characters can be rotated to switch between different characters on their outer periphery, allowing for flexible adjustment of information such as production date and batch number, making operation convenient and time-saving.

Abstract

The application relates to a vacuum sealing device, which comprises a base, a cover, a character assembly and a hot-pressing adhesive strip. The cover is provided with oppositely arranged mounting and pressing ends, and the mounting end is movably connected with the first end of the base. A hot-pressing area is arranged on the fitting surface of the front side of the second vacuum cavity, and a mounting groove is recessed on the hot-pressing area, and the character assembly is arranged in the mounting groove. The character assembly comprises a plurality of character pieces, all the character pieces are arranged side by side in the mounting groove and at least partially protrude from the groove opening of the mounting groove. The hot-pressing adhesive strip is arranged on the hot-pressing area and at least one side of the mounting groove. The outer circumferential side of the character piece is provided with a plurality of recessed characters. The surface of the character piece except the recessed characters is in contact with the vacuum packaging bag for hot pressing, so that the gap of the character periphery during hot pressing of the traditional convex character soft glue code is effectively filled, and the risk of air leakage of the vacuum packaging bag in the hot pressing area is significantly reduced.
