Paint spraying controlling means

The utility model provides a paint spraying controlling means, includes: a displacement mechanism, one bear mechanism, an advancing mechanism, a guiding mechanism and final limit switch group. A slider has on the no rod -type pneumatic cylinder of this displacement mechanism. Should bear the mechanism locates on this slider. This advancing mechanism rigid coupling has a pin on it on this bears the mechanism. This final limit switch group locates this base one side. After the wheel rim gets into the spray booth, this pin by release with the displacement in this bracing piece contact, this bracing piece will promote this advancing mechanism displacement, let the spray gun carry out paint spraying to this wheel rim. In displacement to this final limit switch group response, sensing signal is conveyed to the controlling means of outside to stop carrier gas to this advancing mechanism and on should not having the rod -type pneumatic cylinder, make the pin and should bear the mechanism and return and put the origin
