Description

Technical Field

[0001] This utility model belongs to the field of cardboard processing technology, specifically relating to a quick-assembly structure for a die-cutting paper wheel without a printing plate. Background Technology

[0002] In industries such as packaging printing and paper processing, plateless die-cutting is an important step in cutting cardboard or paperboard into specific shapes. During the cutting of cardboard, paper rollers can transport the cardboard to facilitate subsequent cutting.

[0003] Existing paperboard cutting conveyor rollers, in conjunction with drive rollers, transport paperboard between them, allowing it to be fed into a designated position for cutting. However, with prolonged rotation, the internal materials of the paper rollers, such as the metal components of the shaft and the filling material, age over time. The metal shaft may rust and corrode, reducing its strength and making it prone to breakage, thus affecting the overall structural stability of the paper roller. Therefore, regular disassembly, inspection, or maintenance of the paper rollers is necessary to maintain their good working condition. When replacing a paper roller, multiple fastening components must first be removed to disassemble the roller. After inspection, maintenance, or replacement, the same cumbersome steps must be repeated to reassemble the paper roller. This results in lengthy operation times for each paper roller inspection or maintenance, severely impacting processing efficiency. Utility Model Content
