Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of corrugated board processing equipment, in particular to a corrugated board automatic high-speed die-cutting and creasing device. BACKGROUND

[0002] In the production process of corrugated board, the die-cutting and creasing process plays a key role in the forming of the product. The die-cutting and creasing device for corrugated board is a core component that carries the die-cutting plate and completes the die-cutting and creasing operation. Its performance and operation convenience directly affect the production efficiency and product quality.

[0003] However, the existing die-cutting and creasing device has many problems in the die-cutting plate replacement process. Since the installation position of the die-cutting plate requires high precision, accurate positioning must be performed during replacement, otherwise it will cause die-cutting and creasing position deviation, affecting product quality. The traditional positioning method usually relies on manual operation, and multiple adjustments are made with the help of measuring tools, which is tedious and time-consuming. At the same time, the fixing method after positioning is also complex, often requiring the use of multiple tools for fastening, which is not only inconvenient to operate, but also easy to cause wear and tear of equipment components during frequent die-cutting plate replacement, further affecting the stability and service life of the equipment. This not only increases production costs, but also reduces production efficiency, making it difficult to meet the modern high-speed and efficient production demand.

[0004] The Chinese patent with application number 2020224028457 proposes a creasing and die-cutting device for corrugated board, which includes a bottom plate and a connecting piece. The top of the bottom plate is fixedly connected with four support columns, and the top of the four support columns is fixedly connected with a fixed plate. The inside of the fixed plate is threadedly connected with a screw rod, and the bottom of the screw rod is movably connected with the top of the connecting piece. The bottom of the connecting piece is fixedly connected with a creasing die. The creasing and die-cutting device for corrugated board can move the connecting piece downward by rotating the screw rod, which is threadedly connected with the fixed plate. The knife and the creasing die can be used to simultaneously crease and cut the corrugated board. By setting the screw post, rotating the screw post to make it separate from the limiting groove, the fixed frame, the spring and the fixed pad at the bottom can be disassembled and replaced, avoiding the wear of the fixed pad caused by long-term use, which affects the creasing and die-cutting.

[0005] For the related technology in the above, the inventors found that the above patent cannot improve the replacement efficiency of the die-cutting plate. CONTENT OF THE UTILITY MODEL
