A3-breadth flatbed printer capable of randomly adjusting printing speed and printing precision and method

Abstract

The invention relates to the technical field of printers, and discloses an A3-breadth flatbed printer capable of randomly adjusting a printing speed and printing precision. The A3-breadth flatbed printer comprises a rack, a trigger mechanism and exhaust mechanisms, the rack is internally and fixedly connected with a supporting frame, and the supporting frame is internally and rotationally connected with a rotating shaft. The lower side, close to the rotating shaft, of the supporting frame is fixedly connected with a sliding rail, the surface of the sliding rail is connected with a spray head in a sliding manner, the surface of the rotating shaft is fixedly connected with the triggering mechanism, and the sides, away from the rotating shaft, of the triggering mechanism are movably connected with the exhaust mechanisms, metal contacts are in contact with metal strips, air pumps work and are input into spring air bags through hoses, the spring air bags can expand, so that expansion of the spray head when the spray head moves to the end part can be avoided, the spray head is buffered, vibration of the spray head when the spray head moves to the end part is also reduced, and the stability during printing is improved.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to an A3-format flatbed printer and a method for adjusting printing speed and printing accuracy at will. Background technique [0002] The printer is an important tool in study and work. It can print electronic information on paper, which is convenient for people to carry and store. Most of the current printers have the effect of adjusting the printing speed, which can quickly print on the premise of reducing a certain quality. Printing improves work efficiency. [0003] But now when the printer is printing quickly, because the nozzle is moving back and forth quickly, due to the existence of inertia, the nozzle will collide with the equipment when it moves to the end, resulting in a large vibration and reducing the printing stability. At the same time, when the nozzle sprays a large amount of ink, there will be more ink spray floating inside the printer and cannot be dissipated, c...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an A3 format flatbed printer and method that can adjust the printing speed and printing accuracy at will. The advantages of stability and quality solve the problem of internal floating ink polluting the inside of the printer while making the inside wet, and the nozzle has a large vibration when it moves to the end
