Description

Technical Field

[0001] The utility model relates to the technical field of varnishing machines, in particular to a scraper structure of a varnishing machine. Background Art

[0002] In the production and processing of cans, the varnish box and scraper system are a component of the varnishing machine in the two-piece can production process. After the color printer prints the text and pattern on the can, in order to make the pattern color more saturated and dry quickly; and to protect the pattern on the can and prevent the pattern from being worn during transportation, the varnishing machine is needed to apply varnish (varnish) to the cans with printed patterns.

[0003] At present, the paint box and scraper system of the original structure varnishing machine only have two steel scrapers, which are designed with 0.2mm steel sheets. The scrapers wear quickly and need to be replaced frequently. Long-term operation will also cause certain damage to the varnishing anilox roller. Moreover, the existing technology relies on the cylinder to push the scraper to contact the steel roller. The vibration generated by the equipment during operation, the splashing and solidification of the varnish, will cause the cylinder to return to its position untimely and jam, resulting in the scraper being unable to scrape the varnish evenly. In addition, there is no side scraper in the existing technology, so that the varnish on the end face of the varnishing anilox roller cannot be scraped off, which will cause the paint to fall off, seriously affecting the product quality. For this reason, we propose a scraper structure for a varnishing machine. Utility Model Content
