Description

Waste material regeneration intelligent forming equipment Technical Field The invention relates to the technical field of plastic regeneration, in particular to waste material regeneration intelligent forming equipment. Background Waste recycling intelligent forming equipment is designed for processing such waste materials containing various plastic components, aluminized layers, paper labels, dust and the like, and the equipment directly or indirectly supplies plastic waste to an injection molding unit through a physical processing step so as to realize conversion from waste to recycled plastic products. In the prior art, waste such as waste multi-layer composite bubble bags are used as raw materials for injection molding and the like, if paper scraps and the like are mixed, particularly non-plastic components (such as aluminum films in aluminum plating layers) inherent in the composite structure of the waste multi-layer composite bubble bags are mixed, the impurities can cause foreign matters to be contained in the final regenerated plastic products, so that the qualification rate of the products is reduced, more importantly, air remains in the bubble bag structure, and if the air cannot be effectively removed before the materials enter a melting plasticizing stage, air holes or void defects are formed in the molten plastic, so that the injection molding process is disturbed, and the molded products are finally influenced. In order to solve the above problems, various methods have been adopted in the prior art, including preliminary size reduction treatment of waste materials by a large-sized crushing device, and then air separation or vibration screening are adopted to separate impurities with significant density or size difference, however, for composite layers such as aluminized layers and the like which are tightly combined with plastic substrates, simple crushing and screening operations are difficult to achieve effective stripping and separation, tiny aluminum films formed after crushing are still easy to adsorb or mix in plastic fragments, if such mixed materials containing metal components are directly introduced into an injection molding machine for melt plasticization, quality degradation of regenerated plastic products due to metal pollution is not only caused, even abnormal abrasion or damage of injection molding equipment may be caused, in addition, for the special bubble structure of bubble bags, conventional crushing cannot always ensure that all bubbles are punctured, unbroken bubbles make the crushed materials fluffy in volume, which not only affects the processing efficiency and feeding stability of the materials in subsequent processing procedures, but also has a more direct relation to the effect of melting and degassing stage and quality of final injection molded products. Based on the problems, the invention designs the waste recycling intelligent forming equipment, which aims to solve the problems that when the waste of the bubble bag is recycled, the purity of the material entering the injection molding machine cannot be ensured because the bubbles of the bubble bag cannot be completely released, so that the secondary injection molding quality is affected. Disclosure of Invention The intelligent forming equipment for recycling the waste materials solves the problem that when the waste materials of the bubble bags are recycled and treated, the purity of the materials entering the injection molding machine cannot be guaranteed due to the fact that the bubbles of the bubble bags cannot be completely released, so that the secondary injection molding quality is affected. In order to achieve the above object, the present invention provides the following technical solutions: The invention provides intelligent waste recycling forming equipment which comprises a substrate, a feeding cavity and an injection molding cavity, wherein the feeding cavity is positioned above the injection molding cavity, the injection molding cavity is arranged above the substrate, a crushing roller is arranged in the feeding cavity, a crushing mechanism is arranged at the crushing roller, a centrifugal cavity is arranged below the feeding cavity, a centrifugal tube is arranged at the center of the centrifugal cavity, an air inlet is formed in the side wall of the centrifugal cavity, a filler plate is arranged below the centrifugal cavity, an opening and closing mechanism is arranged at the filler plate, bubbles are eliminated by the crushing roller through the crushing mechanism, and the opening and closing mechanism is periodically opened under the rotation action of the crushing roller by the filler plate. The centrifugal cavity and the centrifugal tube are used for centrifugally screening metal or impurities in the materials, after the materials are torn and crushed, the non-plastic part and the plastic part in the materials are separated at the moment, the plastic part is also formed into a sheet shape under
