A high-precision laser marking machine for bottle caps

Abstract

The invention provides a high-precision laser marking machine for bottle caps, which includes a bottle cap feeding device, a laser coding device, a bottle cap distribution device and a precision control device; The way of arrangement is output backward; the precision control device undertakes the bottle caps output from the bottle cap distributing device in front and back at intervals, and performs high-precision laser coding processing on the front and back of the bottle caps during the transmission process; The front and back sides of the bottle caps that enter the bottle cap distributing device are rearranged and transported to the precision control device in the way of front and back sides spaced apart. After the control device compensates the height during the bottle cap flipping process, it completes the coding on the front and back sides, which solves the technical problem in the prior art that the coding quality is greatly reduced when coding on the second side due to the height difference.

Description

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

Problems solved by technology

[0006] The present invention provides a high-precision laser marking machine 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 facing up and the reverse side is transferred to the bottle cap arrangement. The bottle caps in the device are rearranged by the bottle cap arranging device and then transported to the height compensation device in the way of front and back at intervals. After the height compensation during the flipping process of the bottle cap, and after the flip height compensation, the front and back coding processing is carried out in the coding area, and the automatic height compensation makes up for the existence of coding on the first side and the second side. The height difference greatly improves the quality of bottle cap coding, and solves the technical problem in the prior art that due to the height difference, the coding quality is greatly reduced when coding on the second side
