Embodiment Construction

[0028] The present invention will be further described below in conjunction with specific embodiments.

[0029] Such as figure 1As shown, the existing coating machine structure mainly includes a frame 1, anilox roller 2, rubber roller 3, bottom roller 4 and a chamber 5 for storing paint; wherein, the frame 1 is sequentially arranged from top to bottom 1. The anilox roller 2, the rubber roller 3 and the bottom roller 4, the chamber 5 is in contact with the anilox roller 2 to provide coating for the anilox roller 2, and the scraper 6 is set at the contact between the chamber 5 and the anilox roller 2, It can scrape off the excess paint stuck on the surface of the anilox roller 2, and leave the paint between the anilox gaps on the anilox roller 2; The paint is evenly transferred to the rubber roller 3; the bottom roller 4 and the rubber roller 3 rotate synchronously, and drive the sheet to be coated between the two rollers, so that the paint on the rubber roller 3 can be applied...

Abstract

The invention discloses a cavity scraper structure, an anilox roller coating oil supply device and a coating machine thereof, and belongs to the technical field of coating machines. The coating machine comprises a rack and an anilox roller coating oil supply device installed on the rack, the anilox roller coating oil supply device comprises an anilox roller and the chamber scraper structure matched with the anilox roller, and a pair of scrapers in the chamber scraper structure are matched with the roller surface of the anilox roller; the chamber scraper structure comprises a chamber scraper base body and a supporting mechanism for supporting the two ends of the chamber scraper base body in the length direction; the cavity scraper base body is provided with a cavity for containing coating during coating, and a pair of scrapers capable of being matched with the roller surface of the anilox roller are oppositely arranged on the two sides in the width direction of an opening of the cavity; supporting shafts are arranged at the two ends of the cavity scraper base body in the length direction, and the supporting shafts are rotatably supported in the supporting mechanisms; and the rotating angle of the cavity scraper base body is controlled through the rotating positioning piece. According to the invention, the anilox roller and the chamber scraper can be conveniently maintained.

Description

technical field [0001] The invention belongs to the technical field of coating machines, and more specifically relates to a chamber scraper structure, an anilox roller coating oil supply device and a coating machine thereof. Background technique [0002] The roll coater is a device that applies a certain amount of paint to flat plate materials such as metal plates through a rotating roll. The transfer of paint in the traditional coating machine is carried out by the rotation of a pair of smooth rollers. The size of the paint is controlled by the gap between the pair of smooth rollers. This method needs to be controlled by controlling the gap between the two oil rollers. The thickness of the coating film, the adjustment structure is relatively complicated, and the precision of the oil roller will have a direct impact on the thickness of the coating film, so the processing accuracy requirements for the oil roller are also high. [0003] With the development of technology, the...
