Multi-station positioning device for curve surface container printing press

Abstract

A multi-station positioning device for a curved surface container printing machine, comprising an indexer, an indexing head, a plurality of plate cylinders, and an air distribution mechanism, the plate cylinder is provided with an air flow channel, and the air flow channel is provided with at least One opening; there is a cavity in the indexing head, and the air flow channels of each cylinder are connected with the cavity; the gas distribution mechanism is fixedly installed on the indexer, which includes a gas distribution plate, a vacuum pipe and a compressed gas inlet pipe; The gas distribution plate is located in the cavity of the dividing head, and forms a gap with the inner surface of the cavity. It is connected with the vacuum pipeline; the gas distribution panel is also provided with a compressed gas channel, and the compressed gas channel connects the air flow channel of the cylinder at the exit position of the container with the compressed gas inlet pipeline. The air distribution mechanism of the present invention is relatively simple in structure and small in volume; there is no air leakage or cross-blow-by during the air distribution process, and the operation is reliable and not easy to be damaged.

Description

technical field [0001] The invention relates to a curved container printing machine, in particular to a multi-station positioning device for a curved container printing machine. Background technique [0002] The multi-station positioning device on the existing curved surface container printing machine (for the printing of the conical surface or cylindrical surface on the container) usually includes an indexer, an indexing head and a plurality of plate cylinders, and the indexing head is fixedly installed on the output of the indexer. On the shaft, the plate cylinder is rotatably mounted on the dividing head and distributed at equal intervals along the circumference of the dividing head. The indexer has multiple stations. Driven by the indexer, the indexing head rotates, and the plate cylinder moves around the output shaft of the indexer. It passes through each station in turn and completes the corresponding process to complete the printing on the curved surface of the contai...

AI Technical Summary

Problems solved by technology

At present, in the multi-station positioning device of the curved surface container printing machine, the gas distribution mechanism is usually set outside the dividing head, and the sealing is realized by the tight spring pressure, which is easy to wear and leak, which reduces the reliability of operation, and its volume is large. , the pipeline connection is complex
