Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and in particular to a protective structure for a labeling machine. Background Technology

[0002] Labeling machines contain many high-speed rotating or reciprocating components, such as the labeling head, conveyor belt, and rollers. Protective structures enclose these components to prevent operators' fingers and clothing from coming into contact with the moving parts and causing injury. Protective plates are installed around the labeling head to prevent operators from directly touching the rotating parts of the labeling head during normal operation, thus avoiding injuries caused by entanglement. Furthermore, the frames of the protective structures on labeling machines are typically made of high-strength metal materials, such as stainless steel or aluminum alloy. Stainless steel has excellent corrosion resistance and maintains stable performance in humid or chemically exposed environments, making it suitable for labeling machines in the food and pharmaceutical industries. Aluminum alloy, on the other hand, is lightweight and high-strength, facilitating the installation and relocation of the protective structure while providing sufficient protective strength.

[0003] A search revealed Chinese Patent Publication No. CN221026718U, which discloses a tensioning structure for labeling paper in a bidirectional labeling machine. The structure includes a vertical plate installed on the top of the bidirectional labeling machine. Two labeling paper mounting plates are installed on the front side of the vertical plate. Two guide rollers located below the labeling paper mounting plates are installed on the front side of the vertical plate. Two tensioning adjustment components located below the guide rollers are provided on the front side of the vertical plate. Each tensioning adjustment component includes a rectangular cavity formed on the front side of the vertical plate. This invention rotates the threaded column, causing the threaded sleeve to move. The threaded sleeve, through an elastic movable component, drives the connecting plate to move. The tension roller on the connecting plate can then adjust the tension of the conveyed labeling paper. After adjustment, when the labeling paper is conveyed on the tension roller, the elastic movable component has a certain range of elastic movement, effectively preventing the labeling paper from being too tight or too loose. This achieves the purpose of using elastic tension with adjustable tension, ensuring the labeling paper remains in a stable state. Although the above structure achieves the tensioning effect, it does not consider the lack of protection during the labeling machine's use, which could lead to damage and increase operating costs.
