Thread-free bonding sporting goods and manufacturing method thereof

Abstract

The invention relates to a thread-free bonding sporting goods and a manufacturing method thereof, comprising the following steps: stock preparation, bonding, cutting and combination. In the step of stock preparation, a foam and a sheet made from thermoplastic polyurenthane are prepared and then bonded and cut to form a plurality of connecting blocks provided with the foam and the sheet; in the step of combination, two adjacent connecting blocks form a thread-free bonding strip by means of hot-pressing or high-frequency firm combination; then hot-pressing firm combination is carried out on other connecting blocks in sequence to finishing manufacturing the sports goods; with the method, the effect of reducing manufacturing costs can be achieved without complicated processing and since the same materials are used, the sports goods can be recycled and classified to be effectively reused on the precondition of not being abandoned, thus achieving the effect of environmental protection.

Description

technical field [0001] The present invention relates to a sports article and its manufacturing method, in particular to a seamless joint sporting article and its manufacturing method. Background technique [0002] see figure 1 As shown, the general ball manufacturing method 1 includes a material preparation step 11 , a bonding step 12 , a cutting step 13 , and a sewing step 14 . [0003] see again figure 2 As shown, the material preparation step 11 is to prepare a fabric layer 221 woven from rayon and cotton cloth, and a polyethylene layer 223 . In the bonding step 12 , an adhesive layer 222 is coated on the surface of the fabric layer 221 , and the polyethylene layer 223 is adhered to the fabric layer 221 by the adhesive layer 222 . The cutting step 13 is to cut the polyethylene layer 223 and the woven fabric layer 221 obtained in the bonding step 12 into a predetermined size to obtain a plurality of striking bodies 22 having the polyethylene layer 223 and the woven fab...

AI Technical Summary

Problems solved by technology

[0006] 1. Difficulty in resource recovery and processing: due to the selection of materials, there are fabric layer 221, polyethylene layer 223, and viscose layer 222 woven from artificial fibers and cotton cloth, and there are too many types of materials used. Therefore, for the ball When the balls are damaged and used for resource recovery, it will cause troubles in classification, and it is impossible to simply recycle the waste balls. The fabric layer 221, the adhesive layer 222 and the polyethylene layer 223 must be separated one by one before further processing. reuse, resulting in time-consuming and labor-intensive recycling of resources

[0007] 2. The working environment is not good and the processing is not easy: because the woven fabric layer 221 and the polyethylene layer 223 use a large amount of solvent glue to form the adhesive layer 222, and then the two are bonded together, and a large amount of solvent glue is easy to cause damage during operation. The air is not good and causes the employees to get sick. In addition, the above-mentioned balls are sewn or hand-sewn to sew the two striking bodies 22 together. Therefore, the sewing is limited by the size and type of the balls, and the suitable sewing must be adjusted. Machines and car sewing threads can effectively sew balls together, which requires multiple machines or a large number of sewing personnel to make. Therefore, in the mass production process, it is bound to increase the complicated procedures and increase a lot. Necessary production costs and personnel costs

[0008] 3. It is not easy to repair, so it cannot be reused: in the process of using the ball, if a hole or rupture occurs accidentally, it often needs to be re-sewed, and even if it is to be sewed, it is limited by the need to use a car. The way of sewing is carried out, so the cracked striking body 22 must be unloaded first. When sewing again on the original old seam edge, it is easy to make the repair work difficult because there are too many old seam holes in the seam edge 23. The phenomenon that the strength of the sphere is insufficient, and most of the impactors 22 are cracked in an uneven shape, which is difficult to repair and cannot be reused after being broken, so the spheres are often discarded directly.

[0009] The above-mentioned shortcomings will also occur in the production of other sporting goods, such as protective gear, gloves and other sporting goods, which really bring great inconvenience to users or related businesses. Furthermore, taking the protective gear in sporting goods as an example, most It is made of latex foam material, but due to the poor wear resistance of latex foam material, it is easy to be damaged after being worn and unusable. Therefore, it is really urgent for related industries to improve

[0010] This shows that the above-mentioned existing sporting goods clearly still have inconvenience and defects in product structure, manufacturing method and use, and need to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve
