Description

Technical Field

[0001] The invention relates to the technical field of die-cutting roller maintenance, in particular to a die-cutting roller lifting mechanism. Background Art

[0002] The die-cutting roller is a key component used in the die-cutting process. The roller body is usually cylindrical and is the main part of the die-cutting roller. It provides support and installation foundation for other components. It is generally made of metal materials, such as steel, and has sufficient strength and rigidity to withstand the pressure during the die-cutting process. The die-cutting knife is installed on the surface of the roller body and is the component that directly performs the die-cutting operation. Its shape and size are determined according to the specific die-cutting requirements. The blade is sharp and can cut or indent the material under pressure. The cutting roller and another matching roller rotate relative to each other under power drive. The material to be die-cut is located between the two rollers. When the die-cutting roller rotates, the die-cutting knife on its surface applies pressure to the material, and cuts or indents the material according to the shape and layout of the die-cutting knife to achieve die-cutting processing, flat pressing and flat die-cutting. The roller is used in conjunction with the flat die-cutting machine. During the die-cutting process, the die-cutting roller and the flat anvil move relative to each other to cut the material. This die-cutting roller is suitable for products with high precision requirements and complex die-cutting shapes, such as greeting cards, labels, packaging boxes, etc. The round-to-round die-cutting roller is used in the round-to-round die-cutting machine. The die-cutting roller is cylindrical and continuously die-cuts the material during rotation. The die-cutting knife on the die-cutting roller will gradually wear out during frequent die-cutting operations. As the number of uses increases, the blade will become dull and the cutting effect will deteriorate. When it is necessary to die-cut products of different shapes or specifications, it is necessary to replace different die-cutting knives. For example, if you change from die-cutting square paper boxes to die-cutting round labels, you need to remove the original tool and install a tool that meets the requirements of circular die-cutting.

[0003] After loosening the shaft end fixing device, carefully move the die-cutting roller out of the equipment. If the die-cutting roller is heavy, you can use lifting equipment to assist in carrying it. The current common die-cutting roller lifting mechanism uses an electric hoist to replace the die-cutting roller. The wire rope electric hoist is composed of a motor, a transmission mechanism, a drum, a wire rope, etc. It can be divided into four types according to the different relative positions of the motor and the drum: the motor axis is perpendicular to the drum axis, the motor axis is parallel to the drum axis, the motor is installed inside the drum, and the motor is installed outside the drum. It has the characteristics of fast lifting speed and large lifting weight, and is suitable for various industrial occasions. However, when the existing electric hoist is in use, since the electric hoist uses a drum to wrap the wire rope to achieve the lifting of heavy objects, the wire rope can easily cause the die-cutting roller to shake, thereby increasing the wear of the die-cutting roller and reducing the overall practicality. Summary of the invention

[0004] The purpose of the present invention is to provide a die-cutting roller lifting mechanism to solve the problem that the electric hoist proposed in the above background technology uses a drum-wound wire rope to achieve the lifting of heavy objects, and the wire rope easily causes the die-cutting roller to shake, thereby increasing the wear of the die-cutting roller and reducing the overall practicality.
