Printer

Abstract

The invention relates to a printer. The printer comprises a base on which a guide rail and a tray longitudinally moving relative to the base along the guide rail are arranged, the upside position of the tray is provided with a printing unit, and the base is provided with a dismountable conversion rack on which at least a pair of parallel roller wheels or rollers rotated by the rolling friction force generated by the surface of the tray when the tray longitudinally moves are arranged. When the conversion rack is not mounted, placing an object on the tray and printing on the plane can be realized; when the conversion rack is mounted, a columnar surface object is placed on the roller wheels or the rollers of the conversion rack, and the friction force generated by moving tray and the roller wheels or the rollers drives the roller wheels or the rollers to rotate, and further drives the columnar printed object to rotate so as to print pictures and texts on the columnar surface line by line. Compared with the prior art, no matter printing on the plane or the columnar surface, the problem that a component for placing the printed object runs unstably does not appear, so that the printer can control the printing quality better.

Description

technical field [0001] The printing device of the present invention particularly relates to a printer capable of printing on a plane and a cylindrical surface. Background technique [0002] Present printing equipment generally all can only be printed on the plane, and as the Chinese patent of patent No. discloses a kind of available printer. [0003] The Chinese Utility Model Patent No. 200720020713.X discloses a dual-purpose printer with a cylindrical surface and a plane. Its normal state is to place a cylindrical object on a roller to print on a cylindrical surface. , place the flat plate directly on the roller, and then place an object with a plane on the flat plate to print on its plane. The defect of this structure is that when the tray is placed on the roller, since the tray is simply placed On the roller, the movement of the flatbed is very unstable during operation, and it is easy to cause deviation to one side or even tilt and fall when the center of gravity exceed...

[0003] The Chinese Utility Model Patent No. 200720020713.X discloses a dual-purpose printer with a cylindrical surface and a plane. Its normal state is to place a cylindrical object on a roller to print on a cylindrical surface. , place the flat plate directly on the roller, and then place an object with a plane on the flat plate to print on its plane. The defect of this structure is that when the tray is placed on the roller, since the tray is simply placed On the roller, the movement of the flatbed is very unstable during operation, and it is easy to cause deviation to one side or even tilt and fall when the center of gravity exceeds the support surface when moving, and the printing quality is difficult to guarantee
