Description

Technical Field

[0001] The utility model relates to a mixing device, in particular to a mixing device for producing UV offset printing ink. Background Art

[0002] UV offset printing ink is a high-viscosity paste-like fluid. The resins used to produce the binder of offset printing ink mainly include rosin-modified phenolic resin, alkyd resin, petroleum resin, etc., and there are epoxy acrylate, polyurethane acrylate, etc. According to different boiling ranges, there are various grades of ink oil. The colorants of UV offset printing ink are generally pigments, including organic pigments such as magenta, titanium cyan blue, etc. and inorganic pigments such as titanium dioxide, carbon black, etc. After mixing the binder, pigment, filler and additives, it is dispersed on a grinding machine to obtain the finished product of UV offset printing ink. The solid content of UV offset printing ink is relatively high, and the ratio of pigment to binder before curing is similar to that of ordinary offset printing ink. Therefore, it was first applied in offset printing. UV offset printing ink has no penetration problem during curing and can be printed not only on paper but also on non-absorbent printing materials.

[0003] UV offset printing ink refers to the ink applicable to offset printing presses. Offset printing presses are also called flatbed offset printing presses, so UV offset printing ink is also called lithographic ink. According to different types of offset printing presses, it can also be divided into 4 types: offset printing plastic ink, offset printing metal ink, offset printing matte ink, offset printing fragrance ink, etc. Since the printing speed of offset printing presses is getting faster and faster, and the requirements of printing operators and printing product users for the environmental protection performance of products are also getting higher and higher, ink manufacturers are required to continuously improve the quality of offset printing ink. It is required that the ink has good transfer performance, high coloring power, fast drying speed after printing, long non-skinning time on the machine, and low heavy metal content in the ink product. To meet these requirements, improvements must be made in aspects such as raw material selection, formulation technology, production process, production environment, etc., and the production process must be strictly controlled. The existing technologies generally operate step by step while observing to confirm the condition of the ink, which is rather troublesome and extremely time-consuming and energy-consuming.

[0004] Therefore, it is necessary to design a mixing device for producing UV offset printing ink to solve the above problems. Content of the Utility Model

The feed pipe 14 is fixedly connected to the left side of the top of the charging bucket 2. The charging bucket 2 and the feed pipe 14 are interconnected.

[0024] As Figure 1 and Figure 2 shown in the figure, it further includes a discharge pipe 3 and a water pump 4. The discharge pipe 3 is fixedly connected to the front side of the lower part of the charging bucket 2. The discharge pipe 3 and the charging bucket 2 are interconnected. A water pump 4 is installed between the charging bucket 2 and the discharge pipe 3.

[0025] As Figure 3 shown in the figure, it further includes a pushing block 13. The pushing block 13 is fixedly connected to both the left and right sides of the middle and lower part of the stirring rod 7. The pushing block 13 is in rotational contact with the charging bucket 2. The pushing blocks 13 on both sides can scrape the materials on the inner wall of the charging bucket 2.

[0026] As Figure 2 shown in the figure, it further includes a sealing cover 15. The sealing cover 15 is threadedly connected to the top of the feed pipe 14. The sealing cover 15 can cover the feed pipe 14 to prevent dust from falling into its interior.

[0027] As Figure 2 and Figure 6 shown in the figure, it further includes a positioning frame 16 and a charging cup 19. The positioning frame 16 is bolted to the lower part of the front side of the charging bucket 2. The charging cup 19 is placed on the positioning frame 16.

After that, start the servo motor 6. The servo motor 6 rotates the stirring rod 7, thereby stirring and mixing the materials in the charging bucket 2. While the stirring rod 7 rotates, the pushing block 13 pushes the materials at the edge of the charging bucket 2 inward to make the stirring more uniform. After the stirring is completed, since the conveying directions of the first one-way valve 9 and the second one-way valve 11 are the same, after pressing the airbag 10, the gases in the conveying box 8, the first one-way valve 9, the airbag 10 and the second one-way valve 11 are all discharged from the second one-way valve 11. Pressing again, the materials stirred in the charging bucket 2 will enter the stirring rod 7 through the small holes on the stirring rod 7, then enter the conveying box 8, and then flow out from the second one-way valve 11 through the first one-way valve 9, the airbag 10 and the second one-way valve 11 into the charging cup 19 directly below. Technicians can judge whether the mixing is good by the materials in the charging cup 19. After confirming that there is no problem with the materials, place the container directly below the discharge pipe 3, and then start the water pump 4. The materials in the charging bucket 2 will be pumped out through the discharge pipe 3 into the container. After completion, move the rotating rod 17 to the left to disengage from the latch 18, then take out the charging cup 19 for processing. After processing, place the charging cup 19 on the positioning frame 16 to reset it, and then move the rotating rod 17 to the right to engage with the latch 18 for resetting.
