A double-sided laser marking equipment for bottle caps

Abstract

The invention provides a double-sided laser marking equipment for bottle caps, which includes a front feeding device, a reverse feeding device, a laser coding device, a bottle cap arrangement device and a height compensation device; the bottle cap arrangement device is arranged on the front feeding device and One side of the reverse feeding device; the height compensation device is set on the side of the output end of the bottle cap arrangement device, and the laser marking device is set on the output end of the height compensation device, forming a code between the height compensation device and the laser marking device area; by setting up the bottle cap arrangement device, the bottle caps are transported to the height compensation device in the way of front and back sides arranged at intervals, and at the same time, the bottle cap arrangement in the bottle cap arrangement device synchronously drives the height compensation device to perform height compensation during the bottle cap flipping process Finally, the front and back sides are coded in the coding area, and automatic height compensation is performed, which solves the technical problem that the coding quality is greatly reduced when the second side is coded due to the height difference in the prior art.

Description

technical field [0001] The invention relates to the technical field of bottle cap processing, in particular to a double-sided laser marking equipment for bottle caps. Background technique [0002] In the current beverage market, it is generally used to print digital codes, character codes or simple patterns on beverage bottle caps for anti-counterfeiting and promotion, and the practical operability is relatively poor, and the establishment of a traceability system cannot be realized. At present, the technology of similar equipment adopts inkjet coding, printing, labeling, bronzing and other processes to realize the process of engraving or printing labels on the outer surface or inner surface of beverage bottle caps. [0003] Inkjet-printed patterns and QR codes cannot be in direct contact with food, as they are easy to fall off. Printing also has the problem of ink pollution, and the two-dimensional code cannot realize dynamic variable printing, that is, it cannot realize o...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides a double-sided laser marking equipment for bottle caps in view of the deficiencies of the prior art. By setting up a bottle cap arrangement device, the bottle caps in the bottle cap arrangement device are transferred to the bottle caps with the front face up and the reverse side is transferred to the bottle cap arrangement. After being rearranged by the bottle cap arrangement device, the bottle caps in the device are transported to the height compensation device in the form of front and back sides at intervals. After the height compensation, the front and back sides are coded in the coding area, and the automatic height compensation makes up for the height difference between the first side coding and the second side coding, which greatly improves the quality of bottle cap coding , which solves the technical problem that the coding quality is greatly reduced when the second side is coded due to the height difference in the prior art
