Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sand mill technology, specifically relating to a sand-type ink grinding device. Background Technology
[0002] Horizontal sand mills are high-efficiency wet ultra-fine grinding and dispersing machines widely used in non-metallic mineral industries such as coatings, paints, and inks. Existing sand mills use a stirring rod to agitate the grinding zirconium beads inside, causing them to rotate and impact, thereby grinding the ink. However, the existing technology uses a stirring rod to agitate the grinding tank, but there are dead zones within the grinding tank. This causes the grinding zirconium beads and ink to adhere to the dead zones at the bottom of the grinding tank, often resulting in insufficient grinding, low grinding efficiency, and problems with the adhered ink not being ground or removed in time. Summary of the Invention
[0003] To overcome the problems in the prior art where stirring with a stirring rod creates dead zones within the grinding jar, causing grinding zirconium beads and ink to adhere to these dead zones at the bottom of the grinding jar, resulting in insufficient grinding, low grinding efficiency, and the inability to grind or remove the adhered ink in a timely manner, this utility model provides a sand-type ink grinding device. It achieves sand grinding of the ink by rotating multi-stage grinding drums to tumble and agitate the material and grinding zirconium beads. The rotating drums constantly tumble the grinding zirconium beads, and the bottom portion of the drum is constantly changing, effectively preventing the grinding zirconium beads and ink from concentrating and adhering to the bottom of the drum, ensuring timely removal of the ground ink, and guaranteeing sufficient agitation of the grinding zirconium beads and grinding efficiency. The first grinding drum 4, the second grinding drum 5, and the third grinding drum 6, installed coaxially, perform multiple grinding, filtering, grading, and re-grinding processes on the ink, thereby improving the grinding effect and efficiency.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A sand-type ink grinding device mainly includes a base 1, a motor 2, a rotating shaft 3, a first grinding roller 4, a second grinding roller 5, a third grinding roller 6, and a housing 7. The motor 2 is installed inside the base 1, and the housing 7 is horizontally installed on the base 1 via a flange. The first grinding roller 4, the second grinding roller 5, and the third grinding roller 6 are coaxially fixedly installed from the inside out to form a multi-stage grinding roller. The first grinding roller 4, the second grinding roller 5, and the third grinding roller 6 are respectively provided with sieve holes of progressively smaller size. The rotating shaft 3... The rotating shaft 3 is coaxial with and through the multi-stage grinding rollers and is fixedly installed. The rotating shaft 3 is coaxial with the housing 7 and installed inside the housing 7. The rotating shaft 3 is connected to the motor 2 for transmission. The front end of the housing 7 is provided with a feeding chamber 71. The front end of the first grinding roller 4 is provided with a feeding pipe 41. The feeding pipe 41 is provided with a feeding port.
