A kind of foam roller and its processing method

Abstract

The invention discloses a foam roller. The foam roller comprises an outer cladding and a lining column, wherein the outer cladding is a hollow cylinder; a groove is formed at the inner side of the outer cladding; the lining column is arranged in the groove; the surface of the outer cladding is provided with at least one group of buffer regions and massage regions; the surfaces of the buffer regions are in the shapes of circular arcs; spacing slots are formed among buffer regions at intervals; the massage regions are provided with massage convex points which are alternatively distributed; and the lining column is in the shape of a cylinder which is sealed at two ends. The foam roller is low in cost, less in working procedures, short in manufacturing period, scientific in processing method, and energy-saving and environmentally-friendly; the produced foam roller surface material is free of splicing, uniform in thickness, and high in pattern surface-skin strength; a product is bright in appearance, bright in color, durable in use, and is not deformed due to the fact that the EVA lining column is adopted.

Description

technical field [0001] The invention belongs to the technical field of rubber and plastic products, and in particular relates to a foam shaft and a processing method thereof. Background technique [0002] With the continuous improvement of people's living standards, people pay more attention to physical health. Yoga is the preferred item for physical fitness, and foam shafts are ideal auxiliary tools commonly used by yoga practitioners. Most of the foam shafts currently on the market use surface layers. It is a product with patterned EVA material and a plastic hard tube inside that is cut, glued, and molded. Cycle, many processes, long production cycle, low utilization rate of raw materials: the utilization rate of the original EVA board can only reach about 70% through peeling, edge removal and chamfering during processing; in addition, although the glue that can meet environmental protection requirements is used , it can only show that the toxicity of the glue is currentl...

[0002] With the continuous improvement of people's living standards, people pay more attention to physical health. Yoga is the preferred item for physical fitness, and foam shafts are ideal auxiliary tools commonly used by yoga practitioners. Most of the foam shafts currently on the market use surface layers. It is a product with patterned EVA material and a plastic hard tube inside that is cut, glued, and molded. Cycle, many processes, long production cycle, low utilization rate of raw materials: the utilization rate of the original EVA board can only reach about 70% through peeling, edge removal and chamfering during processing; in addition, although the glue that can meet environmental protection requirements is used , it can only show that the toxicity of the glue is currently within the acceptable range, and it is not 100% environmentally friendly; and the strength of the glue seam of the EVA material will be lower than other parts, which will shorten the service life of the foam shaft; the finished product is molded The hardness of the surface pattern varies greatly; since the surface blank of the foam shaft is made of EVA foam material with the same thickness, it will be subjected to different pressures under different depths of the pattern during processing in the shaping mold with the pattern, resulting in product The hardness of the surface is also different (hard on the outside and soft on the inside, the difference is 8-10 degrees). In addition, the inner plastic hard tube will be deformed due to high pressure and improper use, shortening the service life. Therefore, a better quality, more environmentally friendly and durable tube is needed. foam rolling
