The above-mentioned spheroid production requires a cumbersome processing process, such as punching-printing-protective paint. - Baked dry - bottom. Glue -> Baking dry + EPDM ~> Punch - Glue -> PU and EPDM on the stick ~ into the mold hot pressed into the door type - the edge of the ball is glued - baked dry - plane Stick the ball - the ball into the ball mold and the inner steamed 3D round shape. Generally, the surface pattern of the sphere is produced by printing a pattern on the surface of the pellet (plastic) after molding, and then printing a layer of transparent protective paint of about 〇1 〇1 丽. 〇2 丽, for protecting the printed pattern. However, when the sphere is used for a long time, the transparent protective paint on the surface of the sphere will start to wear due to rolling or improper storage, and the transparent protective paint 5 1303179 on the surface will gradually fall off and the protective layer will be worn away. Directly wear off the pattern printed on the surface of the ball, so that the pattern is damaged and blurred, and the original printing. The pattern or pattern on the surface of the ball cannot be recognized. Furthermore, in the above-mentioned conventional spheroid process, since the processing process is too cumbersome, the spheroid is easily bent and the surface of the slab is wrinkled. If the surface of the slab is wrinkled, it cannot be used, and the conventional process produces a spheroid. The defect rate is quite high, and the production efficiency is low and the quality control is not easy. If the ball is formed by the conventional ball, the long-term compression is not only easy to deform, but also the wear resistance is poor, and the pattern on the printed meal ball is easily worn away and is blurred. Unclear, the tear resistance is also weak and will be indirect and slow; the life of the sphere itself. Therefore, due to the above various factors, there are still many things to be changed in the conventional spheroidal process and the resulting spheroids. SUMMARY OF THE INVENTION t is the main purpose of the present invention, and aims to provide a method for preventing the wear of the ball, which is printed on the reverse side of the squeegee before the spheroid is ejected, and is printed on the TPU after the spheroid is formed. On the reverse side of the leather, the front side of the slab will not wear off the printed pattern to maintain the smoothness and integrity of the printed surface. A second object of the present invention is to provide a method for manufacturing a wear-resistant ball, which is characterized in that a TPU is sprayed and foamed (supercritical micro-foaming single Critical Fluid, SCF) to stabilize the formed spherical sheet. Sex, and the elasticity is sufficient after the shot, and the surface of the ball will not wrinkle.

[Embodiment] In order to facilitate the review committee to further understand the structure, use and characteristics of the present invention, the inventors have given a better example and the detailed description is as follows. The present invention relates to a method for manufacturing a wear-resistant ball, which comprises the following steps: (a) printing a pattern on the back of a 7-11 film, drying it and printing it again? 1] gold® oil; (b) hot-blown and trimmed the above TPU film into the mold; (c) placing the trimmed TPU film into the ball mold; (d) injecting TPU foam and The TPU film is bonded, and a stereoscopic spherical sheet has been formed after being cooled. The method of the present invention is described as follows: _ Referring to FIG. 1 and FIG. 2, as described in the step (a), the printed pattern 2 is pre-designed on the surface of a transparent TPU film 1 After the above-mentioned printing pattern 2 is dried, a layer of ρϋ gold oil 3 is printed on the surface of the printing pattern 2. Its PU gold oil 3 can produce a colorful effect on the surface of the printed pattern 2. 5rnm。 The thickness of the ruthenium film 1 is 0. 3rnm. Referring again to Figures 3 and 4, the τρυ film is placed in a mold in step (b) to be heat-drawn and trimmed. The TPU film 1 of the back printing pattern 2 is placed in the mold 5, and then subjected to a heat-shaping forming process and a trimming operation by the molding apparatus 4, and is cut into a three-dimensional spherical sheet-shaped τρϋ film 1 . • As shown in Fig. 5 and Fig. 6, after the above-mentioned tantalum film 1 is formed, as shown in step (c), the cut TPU film 1 is placed in the ball mold 6, that is, the printed pattern 2 Face up, to shoot the molding work. In the injection molding operation as described in the step (d), a TPU foam 7 is injected from the feed port into the pellet mold 6, so that the TPU foam 7 is combined with the TPU film to be combined with the heat. A stereoscopic sphere has been formed. In a preferred embodiment, the TPU foam 7 emitted in the above step (d) has a thickness of 4 mm. In a preferred embodiment, wherein the step (d) is performed by adding nitrogen gas to the TPU foaming 7, the softness of the pellet is better and the elasticity is better. And the TPU foam 7 emitted in the step (d) may be other materials. The formed three-dimensional spherical sheet can be stitched, and can be applied to a hand-sewing process or a seamless process to make a sphere. • The finished ball is printed on the reverse side of the TPU film before the ball is shot. 'When the ball is formed, its pattern is printed on the reverse side of the film. When the ball rolls and rubs to the front of the ball, it will not directly wear the printed pattern. In order to maintain the freshness and integrity of the printed pattern. Furthermore, by using the manufacturing method of TPU foam injection molding, the stability of the pellet after molding is high, the surface thereof is not wrinkled, the elasticity is excellent, and the pellet is ejected. After the direct type into the 3D stereo state j俾 can reduce the traditional cumbersome processing process, and it is easy to cause the spheroids to open when the bending is caused by the force, because the overall production process is relatively simple, in addition to improving the quality of the 1 1303179 ball and reducing In addition to the production time, the cost of process equipment and materials can be greatly reduced. The wear-resistant ball formed by the manufacturing method can improve the cumbersome process of the ball to improve the foaming elasticity and wear resistance, and simplify the overall process to reduce the probability of bad ball generation and improve production efficiency. And quality. The ball formed by using the spheroid is subjected to long-term compression with a low deformation rate, excellent bending strength, and a reduced chance of injury when the ball hits the human body. In addition, the tpu film itself is excellent in abrasion resistance and tear resistance, and is ductile and can improve the life of the ball itself. However, the above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present invention and the contents of the invention. All should remain within the scope of the invention patent.
