a printing device

Abstract

The invention relates to a printing device which comprises a printing platform. A plurality of parallel cross beams are transversely arranged on the printing platform, each cross beam is provided with a guide rail, and a sliding table arranged in the longitudinal direction is arranged on the cross beams; the sliding table is connected to the guide rails in a sliding mode and can move back and forth along the cross beams. The sliding table is provided with a plurality of sprayers, each sprayer is provided with multiple effective working surfaces, the distance between the two effective working surfaces, in the same position, of the adjacent sprayers is a, the width of each effective working surface is b, and a is the integral multiple of b. The printing device further comprises a drying unit capable of drying images printed on printing media. The printing device has the beneficial effects that on the premise that the development and production cost of ink is reduced and the printing cost is not increased, the printing process is changed, a buffering drying time period occurs in the printing process, and an ink drying function is effectively implemented.

Description

technical field [0001] The invention relates to the field of printing, in particular to a printing device. Background technique [0002] The printer is linked by the X-axis servo motor to the synchronous wheel, and the synchronous wheel drives the sliding table of the nozzle group to reciprocate left and right through the synchronous belt. The Y-axis stepping motor drives the pickup roller, and the printing medium passes over the pickup roller. A row of pressure rollers presses the printing medium on the pickup roller, and the printing medium can be moved by turning the pickup roller. Every time the nozzle slide moves in one direction, the printing medium moves once, and the moving distance is proportional to the width of the image printed by the nozzle. Assume that the print width of the nozzle is 10cm each time, and the printing mode is 4 coverage modes (the so-called 4Pass). Then the printing medium moves a distance of 2.5 cm at a time.
