Description

Technical Field

[0001] This utility model belongs to the technical field of ink processing equipment, and in particular relates to a device for crushing and grinding agglomerated pigments. Background Technology

[0002] The ink preparation process begins with mixing deionized water, pigments, and grinding resin according to the formula ratio. This mixture is then stirred for 30 minutes in a high-speed mixer to initially dissolve the powdered pigments. Next, using a high-speed grinding and dispersing device, zirconia beads are added, and the mixture is ground for 2 hours to refine the large pigment particles, facilitating mixing with the solvent and obtaining the base ink. The base ink is then mixed with the film-forming resin according to the specified ratio and stirred in a mixer for 1 hour to finally obtain the ink. Depending on the ink's printing performance and specific requirements, some additives are added to improve its properties.

[0003] The ink is in solid powder form. After adding solvents and additives, it is processed to obtain the finished ink, and finally, various indicators such as color and drying properties are tested. Ink processing workshops, pigments stored for extended periods are exposed to moisture, causing some pigment powder to clump together in the packaging bags, forming lumps of varying sizes. This increases the difficulty of stirring and dissolving during the initial stage of ink processing and also affects accurate weighing. Therefore, this invention mainly addresses the problem of clumped pigment powder in the workshop, solving the issue of pigment clumping affecting subsequent processing and production. Utility Model Content

[0004] The purpose of this invention is to provide a device for crushing and grinding agglomerated pigments, mainly for pigment powders that are clumped together in the workshop, to solve the problem that pigment clumping affects subsequent processing and production.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A device for crushing and grinding agglomerated pigments includes a grinding barrel and a grinding hammer, wherein the grinding barrel includes a cylindrical barrel body and a conical barrel bottom;

[0007] The grinding hammer has a tapered structure on both the upper and lower sides and is coaxially arranged with the grinding barrel. The tapered part of the lower side of the grinding hammer is located at the bottom of the barrel and a gap is reserved between it and the inner wall of the bottom of the barrel to form a grinding groove.

[0008] The device includes a support frame, which is supported on the ground by multiple support legs. The grinding barrel is floated and supported by the support legs. The support frame is equipped with a motor, and the output end of the motor drives the axis of the grinding hammer to rotate through a rotating shaft.

[0009] Furthermore, the upper and lower conical sidewalls of the grinding hammer each have a first crushing ridge, which is arc-shaped, and there are multiple ridges evenly arranged around the circumference of the grinding hammer.

[0010] The inner wall of the grinding barrel is fixed with a second crushing ridge. The second crushing ridge is a strip-shaped structure that extends along the axis of the grinding barrel. There are multiple second crushing ridges that are evenly arranged around the axis of the grinding barrel.

[0011] Furthermore, the support leg is fixed with a support block for supporting the grinding barrel, and a support ring is fixed to the outer wall of the grinding barrel. The support block is supported by a spring between the support rings. A positioning post is sleeved on the spring, and the lower end of the positioning post is vertically fixed to the support block. The support ring has a post sleeve through which the positioning post passes.

[0012] Furthermore, a discharge pipe is connected to the center of the bottom of the grinding barrel, and a ball valve is installed on the discharge pipe.

[0013] This invention offers the following advantages: The grinding barrel is elevated using supporting legs and is also floating, allowing it to move up and down. After clumps of pigment are introduced into the grinding barrel, the larger clumps are located on the upper conical part of the grinding hammer. As the grinding hammer rotates, these large clumps are continuously impacted and compressed by the side wall of the grinding barrel and the grinding hammer, gradually breaking down from the edges into smaller pieces that enter the grinding tank for further grinding. The smaller pieces then directly enter the grinding tank for finer grinding, ensuring that the output is in powder form. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figure 1-3 As shown: A device for crushing and grinding agglomerated pigments includes a grinding barrel 1 and a grinding hammer 2. The grinding barrel 1 includes a cylindrical barrel body and a conical barrel bottom; the upper side of the barrel body is an open side.

[0021] The upper and lower sides of the grinding hammer 2 are both conical structures, and are coaxially arranged with the grinding barrel 1. The lower conical part of the grinding hammer 2 is located at the bottom of the barrel, and a gap is reserved between it and the inner wall of the bottom of the barrel to form a grinding groove 11. The grinding hammer is an integral structure, and the corner position between the upper and lower conical parts is an arc transition, which is used to enlarge the inlet of the grinding groove to facilitate the entry of pigment into the grinding groove.

[0022] The system includes a support frame 3, which is supported on the ground by multiple support legs 31. The grinding barrel 1 is floated and supported by the support legs 31. A motor 4 is installed on the support frame 3, and the output end of the motor 4 drives the grinding hammer 2 to rotate via a rotating shaft 41. The support frame is a circular plate structure used to support the motor above the grinding barrel. There are four support legs, which are evenly distributed. The support frame has perforated holes for external feeding through the opening on the upper side of the grinding barrel.

[0023] The grinding drum is elevated using support legs and is designed for floating installation, allowing it to move up and down. After the clumps of pigment are introduced into the grinding drum, the larger clumps are located on the upper conical part of the grinding hammer. As the grinding hammer rotates, these large clumps are continuously impacted and compressed by the side wall of the grinding drum and the grinding hammer, gradually breaking them down from the edges into smaller pieces that enter the grinding tank for further grinding. The smaller clumps then directly enter the grinding tank for fine grinding, ensuring that the output is in powder form.

[0024] The grinding hammer works on the principle of pressing grinding. When the lumps enter the grinding tank, the squeezing force causes the grinding barrel to float downwards. After being crushed, it returns to its original position, so that the bottom of the grinding barrel is in a state of continuous floating, which helps to improve the crushing effect.

[0025] like Figure 2 As shown: The upper and lower conical sidewalls of the grinding hammer 2 each have a first crushing ridge 21. The first crushing ridge 21 is arc-shaped, and there are multiple ridges, which are evenly arranged around the circumference of the grinding hammer 2. The inner sidewall of the grinding barrel 1 is fixed with a second crushing ridge 12. The second crushing ridge 12 is a strip-shaped structure that extends along the axis of the grinding barrel 1. There are multiple second crushing ridges 12, which are evenly arranged around the axis of the grinding barrel 1.

[0026] The first and second crushing edges work together to increase the stress point of the pigment clumps, improving the crushing and grinding effects. At the same time, the arc-shaped structure of the first crushing edge helps to drive the clumps of pigment to move towards the grinding side.

[0027] Support leg 31 is fixed with support block 32 for supporting grinding barrel 1. Support ring 13 is fixed to the outer wall of grinding barrel 1. Support block 32 is supported by spring 5 between support ring 13 and support block 32. Support ring has a ring structure, and the inner ring side is fixed to the connection between the barrel body and the bottom of the grinding barrel. The spring support makes the grinding barrel float.

[0028] Spring 5 is fitted with a positioning post 33, the lower end of which is vertically fixed to support block 32. Support ring 13 has a sleeve 14 through which the positioning post 33 passes. This allows the support block of the grinding barrel to float stably up and down.

[0029] like Figure 3 As shown: A discharge pipe 6 is connected to the center of the bottom of the grinding barrel 1, and a ball valve 61 is installed on the discharge pipe 6. It is used to discharge the pulverized pigment powder after grinding.

[0030] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
