Seamless spiral winding and laminating molding process and equipment for plastic storage tank

Abstract

The invention belongs to the technical field of drum body manufacturing of plastic equipment, and particularly relates to a seamless spiral winding and laminating molding process and equipment for a plastic storage tank. The molding process is implemented by the following steps of: (1) heating and extruding plastic resin by an extruder and a material belt forming mold to obtain plastic material belts; (2) extruding the plastic material belts to a mold; (3) simultaneously rotating and moving the mold to spirally wind the material belts on the mold; and (4) integrally melting the adjacent material belts under the action of a pressing roller. The molding equipment comprises a mold towing trolley (402), a drum body winding forming mold (202), the extruder (702), the material belt forming mold (602) and the pressing roller (302), wherein the pressing roller (302) is matched with the outer wall of the drum body winding forming mold (202); a support roller (902) is arranged on the mold towing trolley (402); and the drum body winding forming mold (202) is placed on the support roller (902). The molding process and equipment provided by the invention have the advantages of no seam, low raw material consumption, high finished product strength and ideal processing precision.

Description

technical field [0001] The invention belongs to the technical field of plastic equipment barrel manufacturing, and in particular relates to a welding seam-free spiral winding superposition molding process and equipment for plastic storage tanks. Background technique [0002] At present, there are two kinds of manufacturing processes for plastic cylinder equipment. One is the traditional method, which uses plastic plates to simmer and weld the molding process; the other is a new method, which uses the non-welded spiral winding superposition molding process. [0003] Some plastic cylinder equipment is manufactured by plastic plate simmering and welding. At the same time, it is limited by the width and thickness of the plastic plate. When manufacturing long cylinders (L>1500mm) and thick cylinders (T>30mm), The main disadvantages of the above-mentioned manufacturing process include: (1) There are welds, the strength is reduced, and leakage is easy to occur; (2) The consum...

Problems solved by technology

[0003] Some plastic cylinder equipment is manufactured by plastic plate simmering and welding. At the same time, it is limited by the width and thickness of the plastic plate. When manufacturing long cylinders (L>1500mm) and thick cylinders (T>30mm), The main disadvantages of the above-mentioned manufacturing process include: (1) There are welds, the strength is reduced, and leakage is easy to occur; (2) The consumption of raw materials is large; (3) ) Welding workload is large

The winding molding mold in the existing spiral winding superposition molding equipment still has technical defects such as complex structure, poor expansion and recovery effect, and low processing accuracy.
