Technical Field

[0001] This utility model relates to the field of five-star chair leg processing technology, specifically a burr removal device for processing plastic five-star chair legs. Background Technology

[0002] Five-star chair legs, also known as five-claws, are commonly found in the bases of furniture such as office swivel chairs, ergonomic chairs, bar stools, hair salon chairs, sofas, and dining tables. Their main function is to serve as a supporting structure for the furniture, bearing the weight of the furniture and the user, and providing stability.

[0003] In the processing of five-star chair legs, burrs often remain on the legs. These burrs not only affect the product's appearance but may also negatively impact the user experience. Therefore, the fine removal of burrs from the chair legs is a crucial step. However, in traditional processing methods, each chair leg needs to be manually adjusted by workers before being fed into the burr removal component to ensure precise alignment between the chair leg and the component. This step is not only time-consuming and labor-intensive, increasing labor costs, but also reduces the overall efficiency of the production line to some extent.

[0004] Therefore, a burr removal device for processing plastic five-star chair legs is proposed. Utility Model Content
