Description

Technical Field

[0001] This utility model relates to the field of wooden pallet processing technology, specifically a corner-cutting device for wooden pallet processing. Background Technology

[0002] Pallets are now used in logistics as tools and platforms for assembling, stacking, handling, and transporting goods and products. They are important logistics equipment that transforms static goods into dynamic goods and have wide application value in commodity circulation. They are generally made of materials such as wood, metal, and fiberboard, and are convenient for loading, unloading, and handling unitized goods. Metal pallets have disadvantages such as heavy weight and high cost, while wooden pallets are the most widely used due to their low price and sturdiness. During the production of wooden pallets, since their edges and corners are generally right angles, for the sake of transportation safety and ease of use, the right angles are usually cut off to make them rounded, thus making them easier for users to use.

[0003] The existing equipment has difficulty fixing the wooden pallet during corner cutting operations. It takes a long time to place the wooden pallet and fix it to the equipment. Moreover, the wooden pallet is very easy to shift during cutting. At the same time, the corner cutting device is inconvenient to operate when dealing with wooden pallets with different corner cutting requirements, and the corner cutting efficiency is low.
