Description

Technical Field

[0001] The utility model relates to a rolling device for round products, belonging to the field of processing thin-wall plastic products. Background Art

[0002] After the injection molding of circular thin-walled plastic products, the injection pressure needs to be increased due to product structure problems. Excessive pressure will leave burrs around the product, which will affect the appearance of the entire product. Therefore, the burrs need to be removed in a standardized manner to ensure that the appearance of the product meets the product appearance requirements. In order to remove the burrs, the traditional method is mainly to use a utility knife to cut the burrs to make the appearance smooth. Workers use utility knives for a long time, which is prone to accidents caused by utility knives. At the same time, since plastic products will harden after cooling, it is difficult to cut with a utility knife and requires force, which is more likely to fail to cut and uneven cutting. In addition, the burrs of products processed by this method have different individual factors due to different manual techniques. The incision of the gate material of some products cannot meet the requirements of the product appearance, the scrap rate is high, and the manual processing efficiency is low. Utility Model Content
