Code punching device for anti-fake printing

Abstract

A code punching device for anti-fake printing comprises a workbench. The workbench is provided with a code punching machine, a pressing device and a transmission device. The transmission device is composed of a supporting frame and a conveying roller with a motor. An arc-shaped groove is formed in the roller face of the conveying roller. The motor is arranged on the supporting frame. A rotary disc is installed on an output shaft of the motor. The edge of the rotary disc is hinged to one end of a connecting rod and the other end of the connecting rod is hinged to the upper portion of a sliding block. The sliding block is matched with a sliding rail. The sliding rail is vertically installed on the supporting frame. A connecting board is arranged on the lower portion of the sliding block. A pressing sheet is arranged on the lower portion of the connecting board. A groove is formed in the workbench and located on the lower portion of a punching nail. According to the code punching device for anti-fake printing, marking and code punching can be completed at one time, work steps are reduced, and work time is saved; ticket paper is fed at intervals, the feeding distance of each time is fixed, so that the code punching positions of tickets of the same batch are unified, and the anti-fake effect is achieved; each time of code punching can be completed in a static state, so that the deflection of patterns or characters printed on the tickets is avoided, and the definition of code punching is guaranteed.

Description

technical field [0001] The invention relates to a special coding device for anti-counterfeit printing. Background technique [0002] Coding is the process of printing patterns or text on the surface of the product by spraying during the printing process. In the ticket printing process, the unique pattern or text mark is printed on the ticket by coding to play an anti-counterfeiting role. A single ticket is separated from the whole roll of ticket paper. It is most convenient to code a roll of ticket paper at one time. After coding a roll of ticket paper, it is marked to facilitate separation. At present, the existing coding machine directly codes the ticket paper. After coding, a separate device is required for marking to facilitate division. It requires two steps and two machines to complete, at least two operators, and the production cost is high; During the coding process, since a single roll of tickets is continuously in and out, the coding process is dynamic, and the ...

Problems solved by technology

At present, the existing coding machine directly codes the ticket paper. After coding, a separate device is required for marking to facilitate division. It requires two steps and two machines to complete, at least two operators, and the production cost is high; During the coding process, since a single roll of tickets is continuously in and out, the coding process is dynamic, and the coding position is prone to deviation, resulting in inconsistent coding positions of the same batch of tickets, resulting in unusability and waste; moreover, The ink sprayed on the ticket in the dynamic process is prone to offset, and the clarity of the pattern or text is low
