A blow molding device for smooth discharge of plastic film

Abstract

The invention discloses a plastic film blow molding device with stable discharge. The outer wall of the mixing barrel is rotatably connected with a turntable, the bottom of the stirring shaft penetrates through the mixing barrel and is fixedly connected with a sliding plate, and the bottom of the mixing barrel A storage bin is fixedly connected, the front side and the rear side of the storage bin are provided with water cavities, a number of cooling pipes are fixedly connected between the water cavities, and the bottom right side of the storage bin is fixedly connected with a delivery pipe , the right side of the conveying pipe is fixedly connected with a blow molding machine, the top of the blow molding machine is fixedly connected with a support, the support is provided with a smooth conveying mechanism and a multi-stage guiding compound mechanism, and the top of the base is fixedly connected There is a platform, the top of the platform is equipped with a lifting mechanism and a dust removal box, the bottom of the platform is movably connected with a slide plate, and the bottom of the slide plate is rotatably connected with a winding roller. The present invention can fully mix the raw materials and then cool them for storage. During blow molding, it can be smoothly conveyed, buffered and guided for compounding, stretched for dust removal, and recycled for winding.

Description

Technical field: [0001] The invention relates to the field of machinery, in particular to a plastic film blow molding device with stable discharge. Background technique: [0002] Plastic film Films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging, and as lamination layers. Plastic packaging and plastic packaging products account for an increasing share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging , quick-frozen food packaging, cooking food packaging, fast food packaging, etc., these products have brought great convenience to people's lives.

AI Technical Summary

Problems solved by technology

Before the plastic film is produced, the raw materials need to be fully mixed to ensure the quality of the product. The existing mixing device does not mix the raw materials well. After the plastic film raw materials are fully mixed, they need to be cooled and stored to provide a stable storage environment. In order to ensure the quality of the product, the structure of the existing storage device is too simple, which leads to insufficient functions. The plastic film will be affected by gravity or the external environment during the process of blow molding to composite film formation, resulting in unstable transportation. The plastic film needs to be guided during the roller process. Direct compounding will cause damage to the plastic film just after blow molding and affect product quality. A certain distance buffer is required. After the plastic film is compounded into a film, the plastic film needs to be pulled Stretching to improve toughness. During the stretching process, dust in the air will adhere to the surface of the film. After production, the plastic film needs to be stored by a winding device. The existing winding device cannot handle the plastic film during the winding process. The positioning of the film causes the film to be biased during the winding process, and it is also inconvenient for the upper axle to move the winding roller up and down.
