Digital-printed glass preheating device

Abstract

The invention discloses a digital-printed glass preheating device. The digital-printed glass preheating device comprises a case and a photosensitive drum; the case is internally provided with the photosensitive drum; and a lifting seat is arranged under the photosensitive drum, and the bottom surface of the lifting seat is connected with the bottom surface of the case through a lifting rod. The digital-printed glass preheating device has the beneficial effects that a heating roller is adopted, the interior of the heating roller is provided with a first heating wire, the first heating wire is heated after being powered on, and an inner barrel is heated through heat transfer; the inner barrel makes contact with rolling steel balls, and heat is transferred to an outer barrel through heat transfer; and the outer barrel makes contact with a glass and directly heats the glass, the glass is preheated, and preheating is conducted on the glass through action of heat transfer. Compared with a traditional mode that heating is conducted through a heating lamp, the heat transmission efficiency is higher, the temperature of the glass is increased more quickly, meanwhile, when the outer barrel preheats the glass, the glass is driven by a driving roller to rotate, the outer surface of the glass is preheated more uniformly along with relative rotation of the outer barrel and the glass, and thepreheating effect is better.

Description

technical field [0001] The invention relates to the technical field of glass printing, in particular to a digital printing glass preheating device. Background technique [0002] With the advancement of technology and the improvement of people's living standards, some contemporary young people will print their own photos on the surface of the glass to show their personality. At the same time, some companies will print their company's logo on the surface of the glass. LOGO, as a gift to customers, to achieve the role of publicity. [0003] Digital printing glass needs to be preheated. Generally, the glass and photosensitive drum need to be preheated at the same time to enhance the printing effect. The traditional preheating device is a preheating lamp, which preheats the glass and photosensitive drum through thermal radiation. , the preheating efficiency is low, and it is easy to cause uneven preheating, which affects printing. [0004] Aiming at the problems in the related ...
