Description

Technical Field

[0001] The utility model relates to the technical field of anilox roller painting, in particular to an adjustable scraper mechanism for a micro-concave anilox roller. Background Art

[0002] Release film refers to a film with a separable surface. When the release film comes into contact with a specific material under limited conditions, it is not sticky or has slight stickiness. Usually, in order to increase the release force of the plastic film, a silicone release agent is applied to the surface of the film material, such as PET, PE, OPP, etc.

[0003] The reference patent name is: an adjustable scraper mechanism for a micro-concave anilox roller (authorization announcement number: CN208484383U) includes a coating groove and an anilox roller, the anilox roller is installed on the coating groove through the rotating shafts at both ends, and the end rotating shaft of the anilox roller is connected to the scraper assembly through a rotating rod; the rotating rod includes a ring sleeve and a connecting rod; the peripheral side of the ring sleeve is fixedly connected to one end of the connecting rod, and the ring sleeve is rotatably connected to the end rotating shaft of the anilox roller; the scraper assembly includes a scraper shell and a scraper; a plurality of lifting rods are slidably connected to the bottom surface of the scraper shell; a sleeve is fixed to the two end surfaces of the scraper shell through a plurality of adjusting bolts, and the angle between the sleeve and the scraper assembly and the gap between the scraper and the anilox roller are changed by the above-mentioned adjusting bolts, thereby adjusting the contact angle α and avoiding hard contact between the scraper and the anilox roller, thereby ensuring the pore volume ratio of the anilox roller and the uniformity of the surface coating of the film material;

[0004] Although this patent can adjust the angle of the scraper, the scraper cannot be locked after adjusting the angle. This may result in the scraper angle not being able to be stably locked. Then the contact state between the scraper and the anilox roller will change continuously, resulting in unstable coating amount, thus affecting the quality and consistency of the product. In addition, frequent changes in the scraper angle may increase the friction between it and the anilox roller, which may accelerate the wear of the equipment in the long run and even cause damage to the equipment.

[0005] Therefore, it is necessary to provide a new adjustable scraper mechanism for a micro-concave anilox roller to solve the above technical problems. Utility Model Content
