Description

Technical Field

[0001] This utility model relates to the technical field of carton creasing equipment, specifically a carton creasing device for carton production. Background Technology

[0002] In the carton production process, the creasing process is a crucial step. It provides an accurate trajectory for the folding and shaping of the carton, directly affecting the forming quality and performance of the carton. Currently, there are various carton creasing devices on the market to meet the production needs of cartons of different sizes and types.

[0003] A search revealed a patent, CN221641915U, which discloses a cardboard box creasing device for cardboard box production. The device includes a base with support feet at each of the four corners of the base's bottom. The base has symmetrically spaced limiting grooves along its two longer edges at the top, and a cavity is formed between these grooves at the top. This invention utilizes a cardboard box creasing device designed for cardboard box production. Two fixed blocks move outside two threaded rods, causing two support plates to move away from each other, facilitating adjustment according to the required dimensions of different cardboard boxes. Rotating the fastening bolts lowers the limiting plates to fix the cardboard box and prevent displacement during creasing. An electric telescopic rod extends, causing the pressure plate to descend and align with the top edge of the support plates to creasing the cardboard box. This effectively solves the problem that traditional cardboard box creasing devices are inconvenient for adjusting to cardboard boxes of different sizes and crease positions.
