Code printing device

Abstract

The invention discloses a code printing device, which comprises a code arrangement mechanism, wherein the code arrangement mechanism comprises at least one driving wheel, driving levers and a character code connecting component, wherein the driving wheel is constructed by a hollow cylinder and is provided with a plurality of mounting grooves along the axial direction; the driving levers drive the driving wheel to rotate along a center shaft; the character code connecting component is connected to the driving wheel in a sliding manner, the character code connecting component comprises blocking pieces, elastic pieces, character code blocks and connecting rods, wherein each blocking piece is positioned in the corresponding mounting groove; each elastic piece is arranged between each blocking piece and the bottom of the corresponding mounting groove; the character code blocks are positioned on the lower side of the driving wheel; the connecting rods are respectively fixedly connected to the blocking pieces and the character code blocks, and each connecting rod penetrates between each mounting groove and the bottom surface of the driving wheel. The code printing device solves the technical problems that the code printing device in the prior art is not suitable for code printing in a deeper position and a machine head needs to occupy a larger space, and the code printing device capable of freely encoding while exchanging the contents of a matrix is provided.

Description

technical field

[0001] The invention belongs to the field of hard printing equipment, in particular to a coding device. Background technique

[0002] Sand mold coding often has a variety of digits. In the existing technology, when typing or coding operations in the process, manual operation is required to change characters, which affects the continuity of the coding process. Perform casting to form digital codes, and manually code the prefixes, which wastes manpower and is cumbersome to operate. Although the existing roller type coding machines can realize mechanized coding, their mechanical volume is relatively large. During the coding process, it is necessary to Putting the entire device close to the coding area takes up a lot of space, especially not suitable for coding operations in small and deep areas.

[0003] Chinese patent document CN200960770Y discloses a coder, which realizes printing numbers on molding materials by designing wheel discs with different digits on ...
