Description

Technical Field

[0001] This utility model relates to the field of sports equipment manufacturing technology, and in particular to a ribless, fully-fitting basketball edge pressing device. Background Technology

[0002] The stemless full-fit basketball edge pressing device is a key piece of equipment used in the field of automated basketball production. It is used in the basketball manufacturing process to perform stemless full-range pressing on the edges of various spliced ​​parts of the basketball outer skin. Its function is to eliminate the stem marks produced by traditional basketball edge pressing, ensure that the basketball surface is smooth and flat, and at the same time achieve a tight fit of the outer skin edges, thereby improving the overall appearance quality, structural stability and feel of the basketball.

[0003] Traditional stemless full-fit basketball edge pressing devices consist of a fixed frame, a static pressing mold, a drive cylinder, and a control switch. In actual use, the operator must first place the basketball blank to be pressed into the static pressing mold, and then the drive cylinder pushes the static pressing mold downward to perform the pressing operation. When pressing basketballs of different sizes or models is required, the position of the pressing mold and the pressing spacing cannot be adjusted, and the entire pressing mold must be replaced. This not only increases the equipment investment cost, but also significantly extends the production changeover time and reduces the overall production efficiency.

[0004] The existing solution involves adding a manual adjustment knob and a slide rail structure to the device. By manually rotating the adjustment knob, the pressing mold moves along the slide rail, achieving preliminary adjustment of the position and spacing of the pressing mold. However, due to the influence of material ductility and cutting accuracy during the processing of basketball blanks, there will be certain dimensional deviations and shape differences. The improved device can only perform manual adjustment at fixed positions and does not have an adaptive adjustment function, which seriously affects the consistency of the pressing effect, resulting in inconsistent quality of the produced basketball products and increasing the product defect rate. Therefore, a stemless, fully-fitting basketball edge pressing device is proposed to solve the above problems. Utility Model Content
