Description

Plastic Blow Molding System

This work is related to plastic hollow molding, especially to the technical improvement of a plastic hollow molding system.

Plastic hollow bodies (such as hollow containers) are often formed by molding mechanisms. The molding mechanism sends plastic raw materials to a plasticizing unit for heating and melting, and then injects them into the mold for molding. With the rise of environmental awareness today, many plastics are recycled or mixed with new materials, such as the burrs on plastic bottles or recycled hollow bottle materials.

However, plastic recycled materials, such as polyester pellets, are copolymer polymers. If they are too moist, they will cause problems such as high viscosity after melting, high sink coefficient, and difficulty in stretching during the manufacturing process. In addition, plastic recycled materials are prone to sedimentation in the mold, resulting in poor quality of the manufactured plastic hollow body.

Therefore, it is necessary to provide a novel and advanced plastic hollow molding system to solve the above-mentioned problems.

The main purpose of this invention is to provide a plastic hollow molding system that can effectively dehumidify and dry materials.

To achieve the above-mentioned purpose, the present invention provides a plastic hollow molding system, including: a dehumidification and drying device, including a storage barrel, at least one preparation barrel and a dehumidification and drying unit, the dehumidification and drying unit is connected to the at least one preparation barrel for dehumidifying and drying the material stored in the at least one preparation barrel; and a hollow molding machine, including a feeding unit, a heating unit and a mold unit, the heating unit is connected to the feeding unit and the mold unit; wherein the material in the at least one preparation barrel is sent into the feeding unit after being dehumidified and dried by the dehumidification and drying unit.

The following is merely an example to illustrate possible implementations of the present invention, but it is not intended to limit the scope of protection for the present invention. The "one" or "at least one" preceding the terms mentioned in the text does not limit the quantity, and it can also be "plural" according to needs. This change in quantity is also within the scope of protection, which should be stated in advance.
