Description

Technical Field

[0001] This utility model relates to the field of forming machine technology, specifically to a roll for a cold bending U-shaped forming machine. Background Technology

[0002] A carton forming machine, also known as a carton erecting machine, is a specialized piece of equipment that automatically completes carton opening, forming, and bottom flap folding. It simultaneously applies tape to the bottom of the carton, opens the folded cardboard box, folds the bottom of the carton according to a specific procedure, seals it with tape, and then conveys it to a carton packing machine. Automatic carton forming machines and automatic carton erecting machines are production line equipment for large-scale automated carton opening, automatic bottom flap folding, and automatic bottom tape sealing. The machines are all controlled by PLC and a display screen, greatly simplifying operation and making them indispensable equipment for automated mass production.

[0003] Forming machines come in various forms and are used in a wide range of fields. Cold-bending U-shaped forming machines are used in metal processing. These machines require rollers, as disclosed in Chinese patent CN1046573C, primarily used for grinding or disassembling different materials. This type of roller is commonly used when there is a conflict between roller deformation and a constant roller gap, especially under high loads. This invention aims to further improve synchronous rollers to achieve variable adjustment at different operating points while maintaining a constant roller gap. This is achieved by installing elastic elements between the core and the sleeve of the roller. While the aforementioned patent achieves this by installing elastic elements between the core and sleeve, it does not provide corrosion resistance, making the roller susceptible to corrosion and resulting in a short service life, thus affecting normal use.
