Manufacturing method of ball fabric manufactured through thermoplastic polyurethane material

Abstract

The invention discloses ball fabric manufactured through a thermoplastic polyurethane material and a manufacturing method of the ball fabric. The manufacturing method comprises the steps of firstly, adding a foaming agent into the thermoplastic polyurethane material for foaming; then, carrying out extrusion molding on the thermoplastic polyurethane material, so as to obtain a thermoplastic foamed material; then, rolling the thermoplastic foamed material to obtain a sheet semi-finished product; then, carrying out surface embossing on one surface of the sheet semi-finished product, so as to print a reserved pattern on the surface to obtain a sheet embossed product; then, cutting the sheet embossed product, so as to obtain a plurality of connecting piece bodies; then, overlapping parts of the two adjacent connecting piece bodies, and carrying out high-frequency welding, so as to obtain connecting skin; and finally, carving at least one groove mark on the surface, with the reserved pattern, on the connecting skin at high frequency, so as to obtain the ball fabric.

Description

technical field [0001] The invention relates to a ball fabric, in particular to a method for manufacturing a ball fabric made of thermoplastic polyurethane material. Background technique [0002] Modern people live a busy life. In order to maintain their health and posture, they will engage in various sports to maintain or strengthen their physical functions and enhance their immunity. General sports include running, ball games, swimming, etc. Among them, Ball games such as basketball, volleyball, tennis, and badminton are the most popular. Compared with other sports, not only the threshold for learning is lower, but also a national sport suitable for all ages and fun with friends. In addition, because of their activities The venue is not limited to indoor or outdoor, therefore, it has become one of the best choices for fitness and leisure activities in daily life. [0003] Taking basketball as an example, the selection direction can be based on the basketball specification...

AI Technical Summary

Problems solved by technology

However, conventionally used rubber materials do not have the characteristics of shortening the vulcanization time, not only cannot shorten the process time, but also cannot reduce the energy consumption required, and do not have the effect of environmental protection and energy saving

[0011] Two, not in line with economic benefits

[0012] The existing technology is to use PU material to manufacture basketballs. Since PU is mostly produced by casting molding, the waste generated in the process of manufacturing the PU layer (overflowing burrs, extruding waste rubber), and NG waste from production defects will eventually appear. Waste products can only be recycled through recycling stations, but cannot be directly returned for reuse, which is not economical

[0013] 3. Poor process efficiency

[0014] At present, the rubber layer and the PU layer are bonded with an adhesive, and pressed together mechanically, and then cut into the plurality of panels, and then each panel is bonded to the outer surface of the winding layer with an adhesive, and the A groove is formed between two adjacent panels. Finally, a plurality of rubber strips are bonded to the groove on the vulcanized sphere with adhesive to give the finished basketball a three-dimensional effect. Such a complicated production process not only consumes man-hours, but also increases the Manufacturing cost expenditure, but unable to effectively improve process efficiency
