Technical Field

The utility model belongs to PE wrapping bag preparation field specifically discloses an energy-conserving heat sink of PE wrapping bag blowing machine.

Background

Blow molding (blow molding), also known as blow molding, is a rapidly developing plastic processing method. The thermoplastic resin is extruded or injection molded to obtain tubular plastic parison, which is hot or heated to soften, and then placed in a split mold, after the mold is closed, compressed air is introduced into the parison to blow the plastic parison to cling to the inner wall of the mold, and after cooling and demolding, various hollow products are obtained. The blown film manufacturing process is in principle very similar to the blow molding of hollow articles, but it does not use a mold, and the blown film forming process is generally included in extrusion from the viewpoint of the classification of plastic processing techniques. The blow molding process began during world war ii for the production of low density polyethylene vials. In the late 50 s, the blow molding technology has been widely used with the advent of high density polyethylene and the development of blow molding machines. The volume of the hollow container can reach thousands of liters, and computer control is adopted in some production. Suitable plastics for blow molding are polyethylene, polyvinyl chloride, polypropylene, polyester, etc., and the resulting hollow containers are widely used as industrial packaging containers. At present, the most applied production of PE packaging bags is the production by a blow molding machine. However, in the blowing process, the operation and production requirements of the machine can cause the temperature of some parts to be too high, and particularly, when the screw rod works, a large amount of heat can be generated due to high-speed rotating and stirring, so that when the blowing machine works, the blowing machine is required to be cooled, and products blown by the blowing machine are also cooled by water, and meanwhile, the temperatures of cooling media of a blowing machine body and the products of the blowing machine are different generally and need to be adjusted respectively, so that the existing water-cooling device of the blowing machine is complex, is easy to fail in working, and is high in energy consumption and not environment-friendly.
