Technical Field
[0001] The utility model belongs to the technical field of burr treatment, and particularly relates to a burr treatment device for a plastic hand model. Background Art
[0002] A plastic hand model refers to a handmade sample or a small batch of product prototypes made of plastic materials. Such models are usually used for quickly verifying product designs or for presenting to customers for approval. Their production cycle is relatively short and the cost is relatively low, making them suitable for the initial stage of product development.
[0003] During the production process of plastic hand models, due to small batch production by means of cutting, etc., there are certain burrs at the cutting edges and other positions. Most of the existing burr treatment devices clean the burrs at the edges of plastic hand models by moving on a plane and operate through a workbench capable of collecting burrs. However, this cleaning method cannot well clean the burrs of plastic hand models with irregular shapes, resulting in the need for manual cleaning of the burrs at their edges, which is rather time-consuming and laborious. In addition, during the burr treatment process, some debris adheres to the upper part of the plastic hand model and cannot be removed, requiring manual cleaning after the burrs are removed, and the presence of debris affects the judgment of the burr position. Summary of the Utility Model
