Description

technical field

[0001] The invention relates to the field of sporting goods production and manufacturing, in particular to a large-scale sphere airtightness detection device. Background technique

[0002] Leather balls for sports mainly include football, basketball, volleyball and handball. According to different production processes, they can be divided into two categories: hand-stitched balls and adhesive balls. The structure of leather balls for sports is divided into inner layer, middle layer and outer layer. The inner layer of the ball is the inner layer of the ball, which is used to store compressed air to make the ball elastic. Whether the airtightness of the inner liner of the leather ball is good or not is an important indicator for judging the quality of the leather ball. In the leather ball production workshop It is necessary to test the air tightness of the inner tank of the produced leather balls, because the middle layer and the outer layer of the leather balls...
