Problems solved by technology

[0002] At present, the swimming ring is a ring body, which is inflated or filled with non-inflatable materials. Once the inflated swimming ring is punctured, it can no longer provide floats, and the safety is poor; while the internal filling of non-inflatable materials is generally hard foam. Or filled with sponge, etc., the hard foam is relatively hard, the ring body coat has no support, and the comfort is poor

Embodiment Construction

[0015] Such as figure 1 , 2 As shown, a non-inflatable swimming ring includes an upper half ring body 1 and a lower half ring body 2, the upper and lower half ring bodies are made of foaming materials, and the surfaces of the upper and lower half ring bodies are covered with glue Composite layer 5 and surface layer 6, the junction of described upper and lower half ring body is sewn with slide fastener 7 along, upper and lower half ring body is connected by slide fastener 7, upper half ring body 1 and lower half ring body 2 pass through When the zipper is connected, a hollow cavity is formed inside, and a non-absorbent foam material 3 is filled in the hollow cavity, and a plurality of drainage holes 8 are provided on the surface of the lower half circle.

[0016] The production method of the present invention is as follows: first, the plastic foam material is made into a base plate, and the surface of the base plate is covered with an adhesive layer and a surface layer in turn...

Abstract

The invention relates to an inflation-free swimming ring and a manufacturing process thereof. The manufacturing process comprises the steps that a plastic foaming material is adopted and placed in a storage mold to form a blank, the surface of the swimming ring blank is wrapped with a surface layer, and then final extrusion molding is carried out. As for the swimming ring produced by adoption of the process, the surface layer of the ring body and the internal inflation-free foaming material are integrated, the foaming material is nonabsorbent, soft in texture and high in safety and comfort, the surface layer wrapping the surface plays a role in protecting the internal foaming material, and meanwhile, the appearance of the swimming ring is more attractive.

Description

technical field [0001] The invention relates to a swimming ring, in particular to a manufacturing process of an air-free swimming ring. Background technique [0002] At present, the swimming ring is a ring body, which is inflated or filled with non-inflatable materials. Once the inflated swimming ring is punctured, it can no longer provide floats, and the safety is poor; while the internal filling of non-inflatable materials is generally hard foam. Or filled with sponge, etc., the hard foam is relatively hard, the ring body coat has no support, and the comfort is poor. Contents of the invention [0003] The purpose of the present invention is to provide a non-inflatable swimming ring and its manufacturing process. Plastic foaming material is used to place the foaming material in a mold to form the green body, and then the final extrusion is carried out after the surface of the bad body of the swimming ring is covered with a surface layer. Forming, the surface layer of the...
