Description

Technical Field

[0001] The utility model relates to the technical field of laminating machines, in particular to a laminating machine based on visual automatic sorting. Background Art

[0002] Pulp tableware is a pulp product used to replace plastic tableware. It uses pulp as raw material, and the pulp is made into slurry, and then the pulp is absorbed by the forming mold seat and hot-pressed into pulp products. Since pulp tableware can be recycled and remanufactured, it conforms to the green and environmental protection trend of today's society, so it is widely used in the catering industry. In order to prevent leakage of tableware when serving soup, it is necessary to cover the inside of the tableware with an impermeable film. However, after the tableware is coated, it is inevitable that there will be stains or damage to the impermeable film. If the unqualified coated lunch boxes are not taken out, they are easy to be mixed with qualified coated lunch boxes. At present, most workers stack the coated lunch boxes while picking out the unqualified coated lunch boxes with the naked eye. This method is not only inefficient, but also easy to miss, resulting in mixing with qualified coated lunch boxes, greatly reducing the qualified rate of the product. Utility Model Content
