Lettering head device for realizing three-dimensional printing of steel cylinder

Abstract

The invention discloses a lettering head device for realizing three-dimensional printing of a steel cylinder. The lettering head device comprises a letter disc assembly, a servo speed reducing motor, a slide carriage assembly, shifting forks and a slide carriage; the servo speed reducing motor and the letter disc assembly are installed on the slide carriage assembly, and the whole lettering head device is arranged on a machine head through the slide carriage assembly to form a movable structure; and the letter disc assembly comprises a letter disc, a harmonic gear motor, a hydraulic cylinder and a swing base, and the harmonic gear motor is connected with a letter disc self-rotating mechanism comprising a letter disc so that the letter disc can form a rotatable printing structure. The letter disc of the invention can move up and down, move left and right, swing and rotate automatically so as to achieve three-dimensional lettering; the letter disc can swing freely along the axes of two shifting fork shafts, and it is guaranteed that the spherical surface of the steel cylinder is perpendicular to the letter disc at any time; letters can be formed through continuous rolling and can also be supplemented in an impact mode; and the operation is simple, the automation degree is high, the production efficiency is greatly improved, and the quality is easier to control.

Description

technical field [0001] The invention relates to the technical field of engraving equipment, in particular to an engraving head device for engraving steel cylinders and similar products. Background technique [0002] There are few types of steel cylinder typewriters currently on the market, and the structure is relatively single and the efficiency is low. Basically, it is a simple structure such as hand-held, vertical, horizontal, desktop, etc. The principle adopted is generally to type on a two-dimensional workbench through a printing needle or to type on a rotating steel cylinder by moving the printing needle. Due to structural limitations, resulting in It has defects such as discontinuous typing or easily deformed characters. Specifically, every time a word is printed, a position is changed, which is a form of discontinuous typing; typing without moving the cylinder is similar to typing on a plane with a typing needle, and there is a defect that the characters are easily ...

Problems solved by technology

[0002] At present, there are few types of steel cylinder typewriters used in the market, the structure is relatively simple, and the efficiency is low.

Basically, it is a simple structure such as hand-held, vertical, horizontal, and desktop. The principle adopted is generally to type on a two-dimensional workbench through a printing needle or to type on a rotating steel cylinder by moving the printing needle. Due to structural limitations, resulting in It has defects such as discontinuous typing or easy deformation of characters

Specifically, every time a word is printed, a position is changed, which is a form of discontinuous typing; typing without a fixed cylinder is similar to typing on a plane with a typing needle, and there is a defect that the characters are easily deformed; at the same time, the lettering mechanism is not easy to move and rotate flexibly, resulting in a Complexity, low efficiency, low level of equipment automation, high labor intensity of manual operation, and difficult quality control
