Description

Technical Field

[0001] The utility model relates to the field of sand mills, in particular to a color paste sand mill for water-based ink. Background Art

[0002] Water-based ink is a type of ink that uses water as a dispersion medium and diluent. Compared with traditional solvent-based inks, water-based inks are environmentally friendly, low volatile, and safer, and are widely used in the printing industry. A color paste sand mill is a device used to prepare pigment pastes. It is one of the commonly used grinding machines in the pigment production process. A color paste sand mill is mainly used to mix and grind solid pigments or pigment powders with liquid media to produce uniform pigment pastes.

[0003] A Chinese patent document with authorization announcement number CN218107865U proposes a new closed sand mill for ink production, including a sand mill box, a heat exchange water tank and a feed pipe. A heat dissipation water pipe is wound around the outside of the sand mill box, and a first motor is installed at the middle position of one end of the sand mill box. A feed pipe is installed at the end of the sand mill box away from the first motor, and a second motor is installed on the top of the feed pipe. A heat exchange water tank is installed on the top of the sand mill box.

[0004] In the above application, although the raw materials can be transported to the top of the sanding box, which can have the effect of turning over the raw materials inside the sanding box and making the raw materials evenly mixed, there is a lack of consideration for cleaning. Since ink is a substance with high viscosity, when sanding it, the ink is easy to adhere to the inner wall of the sanding tube and cannot be ground. And when cleaning the sanding tube, because the ink cannot be washed clean by water, it is necessary to manually scrape the ink on the inner wall of the sanding tube. In addition, the existing color paste sanding machine usually requires the sanding tube to be disassembled as a whole for cleaning, which increases the labor burden of the staff, and the color paste remaining inside the sanding tube is easy to drip everywhere during disassembly, which increases the difficulty of cleaning. Utility Model Content

[0005] In view of the problems existing in the background technology, a color paste sand grinder for water-based ink is proposed.

[0006] The utility model provides a color paste sand mill for water-based ink, comprising a machine body; a sand milling tube is arranged on the machine body.

A scraping component is arranged on the sand milling component for scraping off the color paste adhered to the inner wall of the sand milling tube and stirring the color paste near the inner wall of the sand milling tube. A material leakage component is arranged at the lower end of the sand milling tube and discharges the color paste remaining in the sand milling tube by opening the lower end opening of the sand milling tube. And an opening component is arranged at the upper end of the sand milling tube and is opened to observe the sand milling situation in the sand milling tube or clean the inside of the sand milling tube.

[0018] (2) The water-based ink color paste sand mill can be operated by holding the handle and pulling it outward, so that the lower closing plate slides outward along the connecting plates at both ends, and the lower end opening of the sand mill tube leaks out, so that the ink color paste remaining in the sand mill tube flows into the collecting box along the funnel, and the ink color paste residue can be collected, which is convenient for secondary sand milling and utilization, thereby improving the discharge rate. At the same time, it can prevent the ink color paste residue from dripping everywhere, reducing the difficulty of cleaning.

[0019] (3) The water-based ink color paste sand mill can slide the upper closing plate outward along the connecting plates at both ends by holding the second connecting rod and pulling it outward, thereby exposing the upper end opening of the sand mill cylinder to facilitate cleaning of the inside of the sand mill cylinder. There is no need to disassemble the sand mill cylinder as a whole, which saves time and effort for cleaning. It also avoids the phenomenon of ink color paste remaining in the sand mill cylinder dripping everywhere when the sand mill cylinder is disassembled, thereby reducing the difficulty of cleaning and alleviating the labor burden of the staff.

DETAILED DESCRIPTION

[0027] Embodiment 1

[0028] like Figure 1-2 and Figure 5-6 As shown, the utility model provides a color paste sand mill for water-based ink, comprising a machine body 1, a sanding assembly 3, a scraping assembly 5, a material leakage assembly 7 and an opening assembly 6. The machine body 1 comprises a first chassis 101 and a second chassis 102 vertically arranged at one end of the first chassis 101; a sanding barrel 2 is arranged on the machine body 1. One end of the sanding assembly 3 is arranged on the machine body 1, and the other end is arranged in the sanding barrel 2 to sand the color paste. The scraping assembly 5 is arranged on the sanding assembly 3 to scrape off the color paste adhered to the inner wall of the sanding barrel 2, and at the same time stir the color paste near the inner wall of the sanding barrel 2. The material leakage assembly 7 is arranged at the lower end of the sanding barrel 2, and the color paste remaining in the sanding barrel 2 is discharged by opening the lower end opening of the sanding barrel 2. The opening assembly 6 is arranged at the upper end of the sanding barrel 2, and the sanding condition in the sanding barrel 2 is observed by opening the upper end opening of the sanding barrel 2, or the inside of the sanding barrel 2 is cleaned.

[0029] Further, the sanding assembly 3 includes a driving mechanism 31 disposed on the first chassis 101, the driving mechanism 31 is a motor; a driving end of the driving mechanism 31 is connected to a connecting column 32; and a plurality of sanding blades 33 are disposed on the side wall of the connecting column 32. The color paste in the sanding cylinder 2 can be sanded.

[0030] Further explanation, the scraping assembly 5 includes a mounting box 51 rotatably connected to the first chassis 101; a connecting column 32 is arranged through the mounting box 51, and the connecting column 32 is also connected to a first gear 52 in the mounting box 51; a second gear 53 is meshedly connected to one side of the first gear 52; a connecting shaft 54 ​​is provided on the second gear 53; one end of the connecting shaft 54 ​​penetrates the mounting box 51 and is rotatably connected to the mounting box 51, and extends into the sanding tube 2, and a scraping plate 55 is also provided on the connecting shaft 54 ​​to fit the inner wall of the sanding tube 2. Because the viscosity of water-based ink is relatively high, it will adhere to the inner wall of the sanding tube 2 during sanding, and the sanding knife 33 cannot grind it, thereby reducing the discharge rate, so the scraping plate 55 can scrape off the color paste adhered to the inner wall of the sanding tube 2 to improve the discharge rate. At the same time, the color paste near the inner wall of the sand mill 2 is not within the grinding range of the sand mill 33 and has relatively low fluidity, so the scraper plate 55 can be used to stir the color paste near the inner wall of the sand mill 2 to accelerate the flow of the color paste and push the color paste near the inner wall of the sand mill 2 into the grinding range of the sand mill 33 to improve the sanding efficiency. When cleaning the sand mill, the scraper plate 55 can also be driven to scrape off the color paste adhering to the inner wall of the sand mill 2, eliminating the need for manual cleaning, saving time and effort.

[0031] Embodiment 2

[0032] like Figure 1-5 As shown, the present invention provides a color paste sand mill for water-based ink. Compared with the first embodiment, the present embodiment further includes: the sand mill cylinder 2 includes a mounting ring 21 arranged on the first chassis 101; the mounting ring 21 is symmetrically provided with connecting plates 24; the other ends of the two connecting plates 24 are commonly connected to a mounting plate 25; the mounting plate 25 is connected to a discharge port 26. The two connecting plates 24 are commonly provided with a filter plate 4 for filtering the color paste after sand milling, so as to improve the discharge accuracy of the ink.

[0033] Further explanation, the opening assembly 6 includes an upper closing plate 61 slidably connected to the upper ends of the two connecting plates 24; one end of the upper closing plate 61 is movably connected to the first card slot 22 provided on the mounting ring 21, and the other end is set through the mounting plate 25; the upper closing plate 61 opens / closes the upper end opening of the sand mill 2 by sliding on the upper ends of the two connecting plates 24, and the upper closing plate 61 is also connected to the feed port 62. By opening the upper end opening of the sand mill 2, the sand mill 2 can be observed, and the inside of the sand mill 2 can be cleaned conveniently without disassembling the sand mill 2 as a whole, which saves time and effort for cleaning, and avoids the phenomenon that the ink paste remaining inside the sand mill 2 drips everywhere when the sand mill 2 is disassembled, which reduces the difficulty of cleaning and reduces the labor burden of the staff.

[0034] Further explanation, the second chassis 102 is provided with a slide rail 63; a slide plate 64 is slidably connected to the slide rail 63; a first connecting rod 65 and a second connecting rod 66 are respectively connected to the slide plate 64; the first connecting rod 65 is connected to one end of the upper closing plate 61 close to the mounting ring 21; and the second connecting rod 66 is connected to the other end of the upper closing plate 61. The stability of the upper closing plate 61 is maintained to prevent the upper closing plate 61 from shaking left and right or sliding down when the upper closing plate 61 is pushed or pulled.

[0035] Embodiment 3

[0036] like Figure 1-5 As shown, the present invention proposes a color paste sand mill for water-based ink. Compared with the first and second embodiments, the present embodiment further includes: the leakage assembly 7 includes a lower closing plate 71 slidably connected to the lower ends of the two connecting plates 24; one end of the lower closing plate 71 is movably connected to the second clamping groove 23 provided on the mounting ring 21, and the other end is arranged through the mounting plate 25 and connected with a handle 72; the lower closing plate 71 opens / closes the lower end opening of the sand mill 2 by sliding on the lower ends of the two connecting plates 24. After the sand milling is completed, the color paste remaining in the sand mill 2 can flow out from the lower end opening of the sand mill 2, which is convenient for subsequent cleaning. At the same time, the water after cleaning can also flow out from the lower end opening of the sand mill 2 during cleaning.

[0037] Further explanation, the lower ends of the two connecting plates 24 are provided with a funnel 73; the upper end of the funnel 73 is fitted with the lower end opening of the sanding tube 2, which can prevent the ink and color paste from dripping everywhere and reduce the difficulty of cleaning. A collection box 9 connected to the first chassis 101 is provided below the funnel 73, which can collect the ink and color paste residue, facilitate its secondary sanding and utilization, and improve the discharge rate.

[0038] Further explanation, a scraper 8 is symmetrically provided on one side of the mounting plate 25 located in the sanding tube 2; the two scrapers 8 are respectively in contact with the lower surface of the upper closing plate 61 and the upper surface of the lower closing plate 71, so that when the upper closing plate 61 and the lower closing plate 71 are pulled out, the color paste remaining on the upper closing plate 61 and the lower closing plate 71 is scraped off. The color paste remaining on the upper closing plate 61 and the lower closing plate 71 is left in the sanding tube 2, so as to prevent the residual color paste from dripping outside the sanding tube 2, thereby reducing the difficulty of cleaning.

[0039] The working principle of the utility model is as follows: when working, firstly, the ink raw material is introduced into the sand mill 2 from the feed port 62, and then the driving mechanism 31 is started to drive the connecting column 32 and the sand mill 33 to rotate, so that the ink raw material is sanded, and the sanded ink will pass through the filtration of the filter plate 4 and flow out from the discharge port 26. During sanding, the rotation of the connecting column 32 will drive the installation box 51 and the first gear 52 to rotate, so that the second gear 53 orbits around the first gear 52 and rotates at the same time, and then the scraper plate 55 scrapes off the color paste adhering to the inner wall of the sand mill 2, thereby improving the discharge rate, and at the same time, the color paste near the inner wall of the sand mill 2 is stirred to accelerate the flow of the color paste, and the color paste near the inner wall of the sand mill 2 is pushed into the grinding range of the sand mill 33, thereby improving the sanding efficiency. When cleaning the sand mill, the scraper plate 55 can also be driven to scrape off the color paste adhering to the inner wall of the sand mill 2, without manual cleaning, saving time and effort.

[0040] After the sanding is finished, first hold the handle 72 and pull it outward, so that the lower closing plate 71 slides outward along the connecting plates 24 at both ends, and the lower end opening of the sanding tube 2 leaks out, so that the ink paste remaining in the sanding tube 2 flows into the collecting box 9 along the funnel 73, and the residual ink paste can be collected, which is convenient for secondary sanding and utilization, thereby improving the discharge rate. At the same time, it can prevent the residual ink paste from dripping everywhere, reducing the difficulty of cleaning.

[0041] Then, hold the second connecting rod 66 and pull it outward to slide the upper closing plate 61 outward along the connecting plates 24 at both ends, and expose the upper end opening of the sanding cylinder 2, which facilitates the cleaning of the inside of the sanding cylinder 2. There is no need to disassemble the sanding cylinder 2 as a whole, which saves time and effort for cleaning, and avoids the phenomenon of ink and color paste remaining in the sanding cylinder 2 dripping everywhere when disassembling the sanding cylinder 2, thereby reducing the difficulty of cleaning and alleviating the labor burden of the staff.

[0042] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
