Full-automatic blow molding equipment and production process for biodegradable plastic bags

Abstract

The invention relates to the technical field of plastic bag production, in particular to biodegradable plastic bag full-automatic blow molding equipment and a production process, the biodegradable plastic bag full-automatic blow molding equipment comprises a base, a support and a blow molding machine, the blow molding machine is installed on the base, the blow molding machine is used for blow molding molten plastic into a cylindrical film, the support is installed on the base, and an installation platform is fixedly installed on the support; a cooling assembly is arranged on the mounting platform and comprises a cooling cylinder arranged on the support, the inner wall of the cooling cylinder is a smooth inner wall, and the cooling cylinder is located over a discharge port of the blow molding machine. According to the plastic film cooling device, the cooling cylinder is arranged to wrap the outer portion of a plastic film blown out by a blow molding machine, so that it is guaranteed that the wall thickness of the plastic film is uniform, and dust in external air is prevented from adhering to the uncooled plastic film. And the cooling cylinder cools the plastic film in a contact type heat conduction mode, the plastic film does not need to be blown, and it is guaranteed that the wall thickness of the plastic film is not affected by shaking in the cooling process of the plastic film.
