Welding seal type waterborne floating ball and manufacturing process thereof

Abstract

The invention relates to a welding seal type waterborne floating ball and a manufacturing process thereof. The waterborne floating ball comprises a floating ball pipe body and floating ball end covers, wherein the floating ball end covers are arranged on two ports of the floating ball pipe body respectively; steps which are subjected to hot-melt welding together with the floating ball pipe body are arranged on the edges of the opening parts of the floating ball end covers; and rope binding grooves for binding ropes are formed on the floating ball end covers. The manufacturing process for the waterborne floating ball comprises the following steps of: (1) molding the floating ball pipe body and the floating ball end covers on a pull pipe mold and an injection mold respectively by using a polyurethane (PE) material; and (2) sleeving the two floating ball end covers on the two ports of the floating ball pipe body respectively, and welding by using a hot melting machine to ensure that the two floating ball end covers and the floating ball pipe body are enclosed to form a sealed floating ball. The waterborne floating ball has a reasonable design and a simple structure and production process, reduction in production cost is facilitated, production periods are shortened, and production efficiency is improved.

Description

technical field [0001] The invention relates to a water floating ball, in particular to a welded sealing type water floating ball and a manufacturing process thereof. Background technique [0002] At present, the floating ball products are mainly hollow floating balls completed by blow molding technology, and foamed floating balls completed by foaming technology. [0003] Float products made by blow molding process have the following disadvantages: [0004] (1) The cost of the mold is high, the blow mold must be larger than the size of the float, and two sets of molds (parison mold and blow mold) are required, the cost of mold materials is high, and the cost of manufacturing and processing is also high; [0005] (2) The production efficiency of blow molding is low and the cycle is long. Because it is high temperature blow molding, it needs a long and long cooling and setting time, which makes the entire molding cycle of the product long and the production efficiency is low;...

AI Technical Summary

Problems solved by technology

[0004] (1) The cost of the mold is high, the blow mold must be larger than the size of the float, and two sets of molds (parison mold and blow mold) are required, the cost of mold materials is high, and the cost of manufacturing and processing is also high;

[0005] (2) The production efficiency of blow molding is low and the cycle is long. Because it is high temperature blow molding, it needs a long and long cooling and setting time, which makes the entire molding cycle of the product long and the production efficiency is low;

[0006] (3) The quality of the product is prone to instability, the internal stress of the injection molded parison is relatively large, and it is impossible to achieve consistent temperature in each part during the blow molding process, which makes the thickness of the produced floating ball products uneven in some places, and the product is used The weak places in the process are easily damaged, resulting in water leakage and causing losses to users

[0008] (1) Same as the blow mold, the foaming mold must be larger than the size of the floating ball, the cost of mold materials is high, and the cost of manufacturing and processing is also high;

[0009] (2) The foaming production efficiency is low, the cycle is long, and it is also high-temperature foaming, which requires a long and long cooling and setting time, which makes the entire molding cycle of the product long and the production efficiency is low;

[0010] (3) The material cost of the product is high. Since the foam is solid, its material cost is higher than that of the hollow float;

[0011] (4) Foamed floating balls are not easy to recycle plastics, and it is easy to cause white pollution, which leads to a large waste of resources and is not environmentally friendly
