Description

Technical Field

[0001] This utility model belongs to the field of sand mill technology, and more specifically, it relates to a sand mill for the production of UV four-color and spot color inks. Background Technology

[0002] In the production process of UV four-color and spot color inks, the sand milling process is crucial, as it directly affects key quality indicators such as the particle size distribution, fineness, and final printing effect of the ink. As the core equipment for this process, the performance and design of the sand mill play a decisive role.

[0003] In traditional sand mill applications, the installation and disassembly of the grinding cylinder is extremely complicated, making it inconvenient for daily maintenance and cleaning. Furthermore, during the sand milling process, the high-speed friction between the grinding disc and the ink particles generates a large amount of heat. If this heat cannot be dissipated effectively in time, it will cause the ink temperature to rise, thereby affecting the chemical stability and physical properties of the ink. This may lead to problems such as ink discoloration and clumping, seriously affecting the ink quality. Utility Model Content

[0033] Example 3: As shown in the attached document Figure 3 To be continued Figure 5 As shown: Based on Embodiments 1 and 2, the discharge assembly 4 includes: a discharge cylinder frame 401, filter plate A 402, filter plate B 403, and scraper 404; the discharge cylinder frame 401 is rotatably disposed on the outer side of the end of the discharge pipe 305, and a hexagonal hole is opened inside one side of the discharge cylinder frame 401, and a hexagonal structure at the end of the grinding shaft 206 is movably disposed inside the hexagonal hole; filter plate A 402 is fixedly disposed on the inner side of the discharge cylinder frame 401; filter plate B 403 is fixedly disposed inside one side of the discharge cylinder frame 401; scraper 404 is fixedly disposed on the grinding cylinder 305. Inside the 303 grinding cylinder, the scraper 404 is L-shaped, and its inner side is in contact with the outer side of the filter plate A402 and the filter plate B403 respectively. Its specific function is: the discharge cylinder frame 401 can rotate synchronously with the grinding shaft 206, driving the filter plate A402 and the filter plate B403 to rotate; the inner side of the L-shaped scraper 404 fixedly installed inside the grinding cylinder 303 is in contact with the outer side of the filter plate A402 and the filter plate B403 respectively. During the rotation of the filter plate, the scraper 404 can scrape off the particles that are not fully ground on the surface of the filter plate in time, effectively preventing the filter plate from clogging.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In this invention, the raw materials for UV four-color or spot color inks are introduced into the grinding cylinder 303 through the feed pipe 304, and grinding media are added to the grinding cylinder 303. Then, the drive motor 204 is started, which drives the small bevel gear 205 to rotate. The small bevel gear 205 drives the grinding shaft 206 to rotate at high speed through the large bevel gear 207. This causes the grinding discs 208 on the grinding shaft 206 to rotate at high speed in a linear arrangement inside the grinding cylinder 303. Consequently, the ink raw materials can be ground and polished within the grinding cylinder 303. The intense collision, friction, and shearing of the medium cause the particles to deform under stress and generate a stress field; this, in turn, enables the ink to be ground uniformly and thoroughly, effectively reducing the particle size of the ink and improving its fineness and uniformity; simultaneously, the grinding blocks 309 arranged in a ring array inside the grinding cylinder 303 further enhance the grinding effect; coolant flows into the cooling chamber 306 from the inlet pipe 307 and then flows out from the outlet pipe 308, allowing the coolant to circulate within the cooling chamber 306 and ensuring a suitable internal temperature for the grinding cylinder 303; due to the original ink... The high-speed rotation of the material and the feeding pressure of the ink raw material cause the milled ink raw material to pass through filter plate A402 and filter plate B403, and be discharged through discharge pipe 305. During the discharge process, since the discharge cylinder frame 401 is rotatably set on the outside of the end of the discharge pipe 305, and the hexagonal structure at the end of the milling shaft 206 is movably installed in the hexagonal hole inside it, the rotation of the milling shaft 206 will drive the discharge cylinder frame 401 to rotate. The filter plate A402 on the inside of the discharge cylinder frame 401 and the filter plate B403 on one side will filter the ink and remove impurities. The grinding process produces fully ground particles. Simultaneously, an L-shaped scraper 404 fixed inside the grinding cylinder 303 scrapes away particles adhering to filter plates A402 and B403, preventing blockage and ensuring smooth discharge. The starting motor drives the adjusting screw 101 to rotate, which in turn moves the sliding seat 302 via the adjusting base 102, opening the grinding cylinder 303. This design greatly simplifies the installation and disassembly of the grinding cylinder 303, facilitating daily maintenance and cleaning by operators.
