Description

Technical Field

[0001] The utility model relates to the technical field of pigment production, in particular to a three-roller grinder special for pigment production. Background Art

[0002] Pigment production refers to the process of processing natural or synthetic raw materials into powder or paste substances with specific color, hiding power, tinting power and stability through physical or chemical methods. Pigments are widely used in coatings, inks, plastics, textiles and other industries. They are important materials for giving products color and decorative effects. The pigment production process generally includes steps such as raw material preparation, mixing and grinding, dispersion, surface treatment, drying, crushing and packaging. Based on the source and properties of pigments, they can be divided into two categories: inorganic pigments and organic pigments.

[0003] With the increasing demand for environmental protection, modern pigment production is increasingly focusing on reducing the use of heavy metals and harmful solvents and developing low-toxic, environmentally friendly pigments. At the same time, the application of emerging technologies such as nanotechnology and surface modification technology is also continuously improving the performance and application range of pigments.

[0004] A three-roll mill is required in pigment production. The three-roll mill can refine pigment particles and evenly disperse them into a base material (such as resin, solvent, additive, etc.) to form a stable pigment slurry or color paste. However, during the feeding process of the three-roll mill, since the pigment slurry usually contains components such as resin, solvent, additive, etc., these components will make the slurry have a higher viscosity, so it is easy to adhere to the surface of the feeding trough, causing the subsequent discharge of the feeding trough to be blocked. The pigment accumulates in the feeding trough, which will cause the grinder to need to be shut down for cleaning more frequently, thereby extending the production cycle and reducing production capacity. Therefore, a three-roll mill dedicated to pigment production is proposed to address the above problems. Utility Model Content

[0026] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0027] A three-roller grinder specially designed for pigment production includes a body 1, a blanking component 2 is provided on the front side of the body 1, an oscillation component 3 is provided below the blanking component 2, the oscillation component 3 includes an oscillation box 31, a drive motor 33 is provided on the rear side of the oscillation box 31, a snail cam 35 is provided in the inner cavity of the oscillation box 31, an oscillation support rod 36 is provided above the snail cam 35, the top of the oscillation support rod 36 passes through the top wall of the oscillation box 31, and the top of the oscillation support rod 36 extends to the top of the oscillation box 31 and is located below the blanking component 2.

[0028] As a further implementation scheme of this scheme, the unloading component 2 includes a unloading chute 21, which is a trapezoidal setting inclined downward. The upper side of the bottom of the unloading chute 21 is rotatably connected to the front side of the machine body 1 through a hinge shaft 22. A pair of unloading baffles 23 are symmetrically provided above the unloading chute 21. The unloading baffles 23 are fixedly welded to the top two sides of the unloading chute 21, and the length of the unloading baffles 23 matches the length of both sides of the unloading chute 21. The above setting can guide, collect and transport the ground materials to improve production continuity.

[0029] As a further implementation of this solution, the bottom of the shock box 31 is fixedly connected to a support plate 32, and the rear end of the support plate 32 is fixedly connected to the front end of the body 1. The support plate 32 can fixedly support the shock box 31 to ensure the structural stability of the shock box 31.

[0030] As a further implementation of this solution, the output end of the driving motor 33 is fixedly connected to the transmission shaft 34. The front end of the transmission shaft 34 passes through the rear wall of the oscillation box 31 and extends to the inner cavity of the oscillation box 31. The front end of the transmission shaft 34 is fixedly connected to the center of the snail cam 35. The driving motor 33 can provide driving force to the snail cam 35 through the transmission shaft 34 to ensure the normal operation of the oscillation.

[0031] As a further implementation scheme of this solution, a driving pulley 37 is provided at the rear bottom of the oscillation support rod 36. The driving pulley 37 is fixedly connected to the oscillation support rod 36 through a connecting shaft, and the lower surface of the driving pulley 37 is in contact with the upper surface of the snail cam 35. The driving pulley 37 can smoothly contact the snail cam 35 to drive the oscillation support rod 36 to reciprocate longitudinally.

[0032] As a further implementation of this solution, a hinged seat 38 is fixedly connected to the lower side of the bottom of the discharge chute 21, and the top end of the oscillation support rod 36 is rotatably connected to the hinged seat 38. The hinged seat 38 can drive the discharge chute 21 to oscillate when the oscillation support rod 36 reciprocates longitudinally.

[0033] Working process: First, power on all electrical appliances. Machine body 1 can refine the pigment particles and evenly disperse them into the base material (such as resin, solvent, additive, etc.) to form a stable pigment slurry or color paste. The three horizontally arranged metal rollers (front roller, middle roller, and rear roller) in machine body 1 rotate at different speeds to form a shearing zone. The pigment slurry is added between the rear roller and the middle roller. After the first shearing, it enters the narrower gap between the middle roller and the front roller for a second, more intense shearing. After multiple shearing and grinding, the pigment particles are fully refined and dispersed, and finally scraped off from the front roller to complete the grinding. During the grinding process, the discharge chute 21 in the discharge assembly 2 can guide, collect and transport the ground materials to improve production continuity, the hinge shaft 22 can provide a rotation basis for the discharge chute 21, the discharge bar 23 can provide a guiding and shielding effect for the discharge chute 21, and the oscillation assembly 3 can perform regular reciprocating oscillations on the discharge assembly 2, so that it is not easy for the pigment slurry to adhere to the surface of the discharge chute 21, avoiding the discharge chute 21 causing subsequent poor discharge and preventing pigment from accumulating in the discharge chute 21, and the support plate 32 can fix and support the oscillation box 31 to ensure the structure of the oscillation box 31. To ensure the stability of the structure, when oscillating, the driving motor 33 is started, and the driving motor 33 drives the transmission shaft 34 to rotate through the output end, and the transmission shaft 34 synchronously drives the snail cam 35 to rotate clockwise. One part of the snail cam 35 is a slowly rising spiral surface, and the other part is a steep descending surface. When the snail cam 35 rotates at a constant speed, the driving pulley 37 slides along the surface of the snail cam 35 and simultaneously drives the oscillation support rod 36 to move upward. The upward oscillation support rod 36 drives the discharge chute 21 to rotate upward through the hinge seat 38 and the hinge shaft 22. When the driving pulley 37 reaches the snail cam After the wheel 35 reaches the highest point, it will enter a steep descending surface, and the driving pulley 37 will drive the oscillation support rod 36 and the discharge chute 21 to fall rapidly, forming an oscillation. As the snail cam 35 continues to rotate, the driving pulley 37 will drive the oscillation support rod 36 and the discharge chute 21 to repeat the above movement, forming a periodic oscillation output. The "slow rise-steep fall" design of the snail cam 35 can generate obvious impact force and acceleration, which can effectively destroy the adhesion between the material and the discharge chute 21, so that the machine body 1 does not need to be shut down for cleaning more frequently, thereby ensuring the production cycle and improving production capacity.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
