Coating machine

Abstract

The invention discloses a coating machine which comprises a rack, a coating head, a comma doctor roll, a glue retaining mechanism and a driving mechanism, wherein the comma doctor roll and the glue retaining mechanism are erected on the rack; the coating head is arranged at a glue scraping position of the comma doctor roll; the comma doctor roll is positioned above the glue retaining mechanism; an output shaft of the driving mechanism is in transmission connection with the comma doctor roll; and a clamping mechanism is arranged on the comma doctor roll and is used for clamping the comma doctor roll. According to the clamping mechanism, the comma doctor roll is supported, so that the comma doctor roll can be used for a long time and does not easily sag or deform, and the coating quality of the product can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of coating machine equipment, in particular to a coating machine. Background technique [0002] Coating technology is widely used in the coating of substrates such as paper and film and composite packaging. At present, many domestic printing and packaging machinery enterprises use coating lamination equipment, the coating types and squeegee methods are relatively single, and the application of coating technology is also greatly restricted. No matter what kind of coating compound equipment, the key part is the coating head, and the coating and squeegee method used by the coating head will directly affect the quality and effect of coating. [0003] The comma scraper rollers in the coating machine are generally steel rollers with relatively heavy weight, while in the coating machine, the comma scraper rollers are set on the frame at both ends, because the comma scraper rollers are heavy, but among them Becaus...

Problems solved by technology

At present, many domestic printing and packaging machinery enterprises use coating compound equipment, the coating types and squeegee methods are relatively single, and the application of coating technology is also greatly restricted.

No matter what kind of coating compound equipment, the key part is the coating head, and the coating scraping method used by the coating head will directly affect the quality and effect of coating

[0003] The comma scraper rollers in the coating machine are generally steel rollers with relatively heavy weight, while in the coating machine, the comma scraper rollers are set on the frame at both ends, because the comma scraper rollers are heavy, but among them Because there is no support in the middle part, the middle part will be too heavy to sag and deform under long-term use, which will affect the normal operation of the coating machine and even affect the quality of coating
