Description

Technical Field

[0001] The invention relates to the field of rubber ball production equipment, in particular to a rubber ball degassing machine. Background Art

[0002] Existing sports balls mainly use rubber balls made of PVC or rubber materials. After the initial processing of the rubber balls, they need to be inflated to expand to the specified size for subsequent related testing, and then degassing, packaging and transportation: the current degassing method is to manually insert the air needle into the air nozzle, then put the rubber ball into a fixed fixture to squeeze the gas in the ball out, and then manually take out the deflated rubber ball. Because the diameter of the air needle is too small, even with the help of external squeezing such as a cylinder, it still takes a relatively long time for the gas in the ball to be discharged, and it needs to be manually taken out to place another rubber ball. This degassing method has the disadvantage of low efficiency. Therefore, there is an urgent need for a rubber ball degassing device (degassing machine) that can improve the degassing efficiency of rubber balls and reduce the labor intensity.
