Numerical code decorating machine sprayer fixing device and installing method

The invention discloses a numerical code decorating machine sprayer fixing device and installing method. The fixing device comprises a sprayer combination frame, special color sprayer sets, proximate matter, sprayer clamping sleeves and sprayers; and the sprayers are installed in the sprayer clamping sleeves, the sprayer clamping sleeves are arranged on a left rail and a right rail of the proximate matter in a left-and-right crossed manner, slide in and are installed to form the special color sprayer sets, and the two ends of each special color sprayer set are fixed to the sprayer combination frame. The numerical code decorating machine sprayer fixing device has the beneficial effects that the device is adopted, and the machining cost of a sprayer fixing plate can be reduced; the sprayer sets can be accurately positioned without fine tuning, and therefore the digital printing quality is improved; and (3) the sprayers can be rapidly mounted and dismounted, maintaining and repairing are very convenient, and the working efficiency is improved.
