Example Embodiment

[0012] Such as figure 1 As shown, the printer of the present invention includes a base 1. A guide rail 2 is provided on the base 1. The tray 3 can move longitudinally along the guide rail 2 relative to the base 1 under the drive of a stepping motor (not shown in the figure). The base 1 is on the tray 2. The printing unit 4 is provided above the printing unit 4 with a print head 5 that can move back and forth in the left and right directions. The base 1 is also provided with a removable conversion frame 6. The conversion frame 6 is provided with two symmetrical left and right sides parallel to each other. For the roller 7, the roller 7 can rotate relative to the conversion frame 6 driven by the rolling friction force generated on the surface of the tray 3 when the tray 3 moves longitudinally, and the axle of the roller 7 is connected with the conversion frame 6 through a bearing (not shown in the figure); The unit 4 can be adjusted in the vertical direction relative to the base 1....

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...
