Adjustable printing device

Abstract

The present invention discloses an adjustable printing device. The adjustable printing device comprises a body, the body is internally provided with a control circuit board and an ink box storing ink,the lower end of the body is provided with a printing head electrically connected with the control circuit board, and an ink outlet is arranged at the ink box corresponding to the printing head. Roller modules are symmetrically arranged at two sides of the printing head of the body, the roller modules are installed on the body through a regulation mechanism and can regulate the installation height through the regulation mechanism to achieve regulation of a distance from the working surface of the printing head. The roller modules can regulate the distance extruded out of the printing workingend through the regulation mechanism and can return to the side of the body through regulation of the regulation mechanism so as to fit different surfaces to be printed and meet the printing demands of different printing articles, and when the surface to be printed is small and there is a shielding object around, the roller modules can be returned to and located at the side of the body so as to prevent the roller modules from butting against the shielding object, effectively improve the printing quality and widen the application range.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, and in particular relates to a portable printing equipment. Background technique [0002] Portable printing equipment is a kind of inkjet printing equipment derived from traditional printers and can be used in industrial production. The portable printing device can be used not only for information printing on the product packaging box, but also for directly printing information on the product itself. [0003] In traditional portable printing equipment, in order to protect the printing working end, a roller protruding from the surface of the printing working end is generally fixed on the printing working end, and the roller touches the to-be-printed surface of the printed item, so that the printing working end and the to-be-printed surface A certain installation distance is reserved between them. [0004] However, the surface to be printed on different printed items is not all flat, i...

AI Technical Summary

Problems solved by technology

[0004] However, the surface to be printed on different printed items is not all flat, it may be concave, convex, irregular, etc. At this time, the fixed rollers will not be able to meet the protection requirements during the printing process

Or when the area of ​​the surface to be printed is small and there is an obstruction on the surrounding side, the contact of the roller against the obstruction will greatly increase the distance between the printing working end and the surface to be printed, affecting the printing quality
