Description

Technical Field

[0001] The utility model relates to the technical field of self-adhesive paper punching, and more specifically, to a self-adhesive paper punching tool. Background Art

[0002] In modern industrial production, self-adhesive paper has become an indispensable material due to its excellent adhesion performance and diverse application scenarios. Self-adhesive paper is widely used in the fields of commodity labels, logistics identification, anti-counterfeiting labels, etc., providing convenience for information transmission, product traceability, brand protection, etc. However, in the processing of self-adhesive paper, punching is a key process link. By punching holes of different shapes and sizes on self-adhesive paper, the needs of different products and applications can be met, such as hook holes, binding holes, heat dissipation holes, etc. In order to improve the efficiency and accuracy of punching, a special self-adhesive paper punching tool is usually used to complete this task. The punching tool applies pressure on the self-adhesive paper through the punching head, so that the paper is punched and formed according to the predetermined pattern and size. Generally speaking, the punching tool consists of a punching head, a pressing plate, a bottom plate and other components. Among them, the punching head is the most critical component, and its size and shape directly determine the effect of punching. For self-adhesive paper of different specifications and uses, punching heads of different models and layouts are required to meet the requirements of punching. For example, when making self-adhesive labels, it is necessary to punch out positioning holes on the edge of the label for docking with a printer or labeling machine; when making self-adhesive advertising stickers, it is necessary to punch out half-cut lines around the stickers to facilitate users to tear off the stickers. Therefore, the punching tooling must have good adaptability and flexibility, and be able to quickly replace and adjust the punching head to meet different production needs.

[0003] However, the existing self-adhesive paper punching tooling still has some shortcomings in the adjustment of the punching head. First, the punching heads of most punching tools are fixedly installed on the pressing plate. Replacing the punching head requires disassembling the pressing plate, which is cumbersome and affects production efficiency. Secondly, the existing punching head adjustment mechanism mostly adopts a screw fastening method, and the adjustment process requires the use of tools, which is not intuitive and convenient, and is prone to problems of inadequate adjustment or over-tightening, affecting the punching quality. Thirdly, since the self-adhesive paper has a certain viscosity, it is easy to adhere to the punching head during the punching process, affecting the detachment and reset of the punching head, resulting in defects such as incomplete punching or position offset. Most of the existing punching tools use springs to apply a reset force to the punching head, but the elastic force of the spring is often insufficient or severely attenuated, making it difficult to ensure the reliable rebound of the punching head.
