Description of the invention: [Technical field to which the invention belongs] The present invention relates to a method for preparing a VA foam by heating and softening the surface layer of a plate-shaped intestinal foam, which is formed by roller pressing and cooling and solidification. An uneven surface, an ink layer is printed on the surface layer of the package during the process. [Previous technology] Common EVA foams are mostly made into sheet form, and are cut into floor tiles, puzzles or decorations according to the purpose. Based on aesthetic requirements, the surface of these leg foams & inks _ Case or suit, for example: The current type of bile foaming system shown in Fig. 4, mainly cuts the leg material 7 from the mold after ridge shape from the thickness centerline 71. Then, the transfer film 62 is rolled by hot-rolling, so that the ink pattern or color pattern on the transfer film adheres to the surface / body surface 701, because the foam surface will be formed at the same time when the mold is molded. asperities path (with the use of slip feature), so that the ink is not attached over the transfer yield, but order = coffee with a fine, (iv) 4 Na Jie __ run, the mesh outline cut ㈤Μ do The transfer method has not been considered; however, this method is even more troublesome. Before the operation, the foam surface must be thinned to allow the transfer ink to have a better adhesion effect. Printing workers also need to prefabricate and stock transfer film. Furthermore, the leg material needs to be foamed for a long time. Limited production capacity. 、 One bubble produces two sessions of foam, so that

Mainly, the EVA has the problems of the foregoing process, and the other material is foamed from the mold to form the block 8, and then the cross-section from the block is cut into the number of the wrong block 8 0, 1242491, ... The wind 9 1 heats the surface of the EVA foam to soften, and finally rolls the transfer film 9 with a roller g 2 to make the ink pattern or color 9 on the transfer film adhere to the surface of the eva foam. In the case of Asian style, the surface of the EVA foam is formed with a concave-convex pattern by using a concave-convex engraving 9 2 on the surface of the roller. The biggest improvement in this process is that the secondary foaming block can be cut into several pieces of EVA foam, which can increase the production capacity of EVA foams several times. However, it is still necessary to transfer the film to make the ink pattern or color. Although the foaming cost is reduced by the older process, it still cannot reduce the production cost of the transfer film and the problems of prefabrication and inventory. [Summary of the Invention] The main purpose of the present invention is to provide a method for making a bile foam by solving the above-mentioned problems, replacing printing film with printing, so as to greatly reduce the production cost of the ink layer, and solve the prefabrication and inventory. Trouble with transfer film. The other purpose of the present invention is to use the ink layer to have better adhesion to the surface of the hidden foam, and to smooth the pores on the surface of the EVA foam to make it smoother. In order to achieve the foregoing object, the present invention provides a method for making an EVA foam, which mainly uses a relief printing method to make an ink layer from a flat surface layer of the EVA foam. And, by heating and foaming until the surface layer containing the ink layer is softened, and then rolling at low temperature to the jumping foam to solidify the surface layer and form unevenness. The above-mentioned objects and advantages of the present invention can be easily understood from detailed descriptions and drawings of selected embodiments described below. Of course, the present invention allows some differences in the steps or the arrangement of the steps, but the chosen embodiment is shown in the Secretary ’s paper towel, detailed outline, and shown in the drawings. [Embodiment] 1242491 Please refer to Figures 1 and 2, the figure shows the selected embodiment of the method of making EVA foam according to the present invention, this is only for Lang's use, please join in the special office; fLimited by this institution. The manufacturing steps of this embodiment include: (a) taking a plate-shaped foam body having a flat surface layer; (b) A printing relief is made on the surface of the cylinder 2 and the ink is printed on the surface layer 101 of the EVA body using a relief printing method to form an ink layer 11 that is in a relief pattern on the surface of the cylinder. (C) Applying a blower 3 to the ink layer 11 promotes rapid drying of the wine. (d) X blows hot air 4 at a temperature of 100 to 250 C to the surface layer 101 of the EVA foam containing the ink layer and heats it until the flat surface layer is softened. (e) In the silent step (d), the low-temperature roller 5 is pressed against the EVA foam; wherein the low-temperature roller 5 is circulated with cooling liquid to maintain the surface temperature of the roller, and the surface of the warm roller has unevenness. The engraved pattern 51 ′ cures the surface layer 10 1 and forms an uneven shape as shown in FIG. 2. The features of the aforementioned process are: The printing relief system made on the same surface can be made according to the required pattern, and more importantly, the printing work is completed directly on the EVA foam, so the cost of the transfer film is directly saved, and the need for The trouble of prefabricated and stock transfer film. On the right, you need to make a multi-colored pattern, and then perform another one or more consecutive steps ⑻ (c) to make a multi-colored ink layer, that is, set the number of rollers and the relative number of σ people according to the color of the ink. Air-drying can print more ink layers. A hot air is blown to the EVA foam to soften the flat surface layer. It further strengthens the adhesion of the printing ink layer to the EVA foam. Therefore, it is not used to clean the surface of the bile foam before printing. Rolling and pressing against the EVA foam can force the flat surface to be shaped into the unevenness of the unevenness on the surface of the warm roller, and solidified because the flat surface is rapidly cooled by the low temperature roller. 4. After the surface layer of the heated and softened EVA foam is shaped by low-temperature rollers, the pores formed by the original foaming are pressed to be flat and smooth, which further enhances the beauty of this surface. Because of this feature, the use of step (a) plate-shaped EVA foam can be selected—A material is a process of cutting from a mold foaming block into several pieces of EVA foam, that is, a sliced board Although the surface pores of the shaped EVA foam are larger than the surface pores after the mold is foamed, they can still be pressed flat and smooth. 5. Steps (a) to (e) can be completed continuously in the same process equipment, which can effectively improve production efficiency. FIG. 3 is a second embodiment of the manufacturing process of the present invention, and the steps include: (a) taking at least one surface of the plate-shaped EVA foam body having a flat surface layer; ⑸Blow the surface of the muscle foam body 1 〇1 with hot air 4 between 10 ° and 25 ° (rcs degrees) and heat it until the surface is softened. (C) Immediately following step (b) 'With a low temperature roller 5 Rolling towards the leg foam; among them, the low-temperature roller 5 internally uses a cold bribe cycle to maintain the surface temperature of the miscellaneous wheel, and the embossed engraving 51 of the miscellaneous surface causes the surface layer 1Q1 to solidify and form an uneven shape. — The surface of the roller 2 is made into a printing relief, and the ink is printed on the surface layer 1 Q 1 of the EVA that has become uneven with a relief printing method, and the ink layer 1 1 forming a relief pattern on the surface of the roller is applied. ⑷ Apply the ink layer 1! Blow 3 to promptly dry the wine. ^ 1242491 The characteristics of the second EVA foaming process of the present invention are still the same as the improvements obtained by the process described in the first example. The two processes are only in the order of the processing steps. There are differences.
