Description

Technical Field

[0001] This utility model relates to the field of packaging crease production, and in particular to a servo cutting mechanism. Background Technology

[0002] Card packaging is a new type of packaging for fluid and semi-fluid materials. The material is filled into a molded film or sheet, which is then heat-sealed and cut into individual pieces. Before heat-sealing, the sheet needs to be creased to create creases. To open the packaging, simply fold the sheet along the creases. The creases will tear open due to the tearing, and the material can be squeezed out from the tear.

[0003] The public account is " CN115339677A A Chinese utility model patent discloses a card packaging machine, which includes a sheet unwinding roller and a film unwinding roller. A heating component and a thermoforming component are arranged sequentially on one side of the film unwinding roller. An outer indentation component and an inner indentation component are arranged on one side of the sheet unwinding roller. The length of the inner indentation pressed by the inner indentation component is shorter than the length of the crease pressed by the outer indentation component. A three-side sealing component is arranged on one side of the inner indentation component. A filling component, a sealing component, a traction component, and a cutting component are arranged sequentially at the discharge end of the three-side sealing component.

[0004] However, the aforementioned card packaging machine still has the following drawbacks:

[0005] First, the creasing depth and length of the creasing assembly cannot be precisely controlled, leading to uneven edges or inconsistent creasing on the packaged cards, affecting ease of use. Simultaneously, the creasing assembly may cause excessive stretching or tearing of the sheet material during the creasing process, especially during high-speed production, resulting in lower yield rates. It also cannot fully adapt to sheets of different thicknesses or materials, causing inadequate or excessive creasing, affecting the packaging's airtightness and overall quality.

[0006] Secondly, the embossing components suffer severe wear and damage under long-term high-load operation, resulting in a decline in embossing quality. Worn embossing components may cause irregular embossing on the sheet, affecting the functionality of the packaging. Furthermore, replacing the embossing device requires removing the entire unit for replacement and maintenance, increasing operating costs.

[0007] Therefore, it is necessary to improve these technical issues. Utility Model Content
