A rotary printing online punching device

Abstract

The invention discloses a rotary printing online punching device which comprises a first side plate, a second side plate, an upper connecting rod, a lower connecting rod, an upper mold shaft, a lower mold shaft, an upper mold, a lower mold, shaft sleeves, an adjusting mechanism and transmission gears. The first side plate and the second side plate are arranged in parallel. The two ends of the upper connecting rod are fixedly connected with the upper portion of the first side plate and the upper portion of the second side plate respectively, and the two ends of the lower connecting rod are fixedly connected with the lower portion of the first side plate and the lower portion of the second side plate respectively. The upper mold shaft and the lower mold shaft are installed on the first side plate and the second side plate with the upper axis and the lower axis in parallel. The upper mold shaft and the lower mold shaft are connected with the first side plate and the second side plate through the shaft sleeves, and one end of the upper mold shaft and one end of the lower mold shaft are meshed together three the two transmission gears. The rotary printing online punching device is convenient to operate, simple in structure, high in efficiency and precision and wide in applicability.

Description

technical field [0001] The invention belongs to the field of printing machinery, and in particular relates to an online punching device for rotary printing. Background technique [0002] The traditional printing method mostly adopts the method of post-processing after printing, which has the common problems of low production efficiency and difficult quality assurance. With the electronic development of the bill industry, more and more products adopt the method of printing face information on the connected machine to improve the anti-counterfeiting performance of the product and reduce the cost. Such products must meet two basic conditions: The first is the connection type, and the second type meets the requirements of photoelectric reading. The connected type can only use the rotary printing method, and the photoelectric reading can only print black reading blocks or punch holes. Printing black reading blocks may cause difficulty in reading marks of different printing tools...

AI Technical Summary

Problems solved by technology

[0003] The standard commercial bill rotation has a punching function, but it is limited to the standard 4.2MM bill conveying hole. It is integrated with the host, does not have compatibility and expansion performance, and is extremely unchanged for disassembly and maintenance.

If you adopt the method of punching after offline, you need to purchase a continuous paper punching equipment. There is no suitable model in the market for selection. You can only choose a self-adhesive die-cutting machine with Japanese technology to replace it. , the investment needs nearly 100,000 yuan, and it will be an efficient and economical solution to develop a punching device that is compatible with commercial rotary printing machines and has the potential for performance expansion
