Description

Technical Field

[0001] The invention belongs to the technical field of container foil pressing and shaping, and in particular relates to a pressing and shaping device for food-grade container foil. Background Art

[0002] The forming performance of container foil material is not good. If the structural design of the container foil pressing and shaping device is unreasonable, the surface of the produced container foil will be wrinkled or even cracked, which will eventually lead to unqualified container foil. Moreover, the clean surface of the container foil without visible dirt that affects the senses is a key indicator of qualified container foil. The existing container foil pressing and shaping device cannot automatically detect the surface quality of the container foil after pressing and shaping the container foil. The appearance quality inspection of the existing container foil is mainly based on manual sampling, and the quality of the container foil is judged by the subjective observation of the quality inspectors themselves. With the continuous improvement of social productivity and the continuous acceleration of production rhythm, the disadvantages of manual inspection are constantly exposed. For example, the cost of manual inspection is high, but the inspection efficiency is relatively low, and it is easy to miss inspections and misdetections. Moreover, the food-grade container foil pressing and shaping device currently used does not have the function of quickly ejecting the container foil to realize the demoulding of the container foil. Most of them rely on manual demoulding, which not only increases the labor of workers, but also is laborious and inefficient.
