Description

Technical Field

[0001] This utility model relates to the field of pigment dispersion technology, and in particular to a pigment dispersion testing machine. Background Technology

[0002] The raw pigments obtained from the production process usually require further processing such as crushing and drying. During drying, finer pigment particles may agglomerate, increasing their size to many times larger than the original particles. Therefore, they cannot be used directly for coloring and must be dispersed. Besides performance requirements such as hue, tinting strength, hiding power, and various resistances, the dispersibility of pigments directly affects important quality indicators such as color strength, fineness, and gloss of the produced inks and coatings. Good dispersion can also shorten grinding time during coating production. For large-scale dispersion, dispersion tests are generally required first.

[0003] Existing pigment dispersion tests separate the dispersion and collection coloring stages, requiring manual material transfer. Dispersed pigment particles are prone to remain in the equipment cavity or spill during the transfer process, making complete collection difficult. This results in a significant deviation between the test results and the actual dispersion effect, affecting the evaluation of key indicators such as the degree of coloring. Utility Model Content

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0035] The raw pigments obtained from the production process usually require further processing such as crushing and drying. During the drying process, finer pigment particles may agglomerate, making their particle size many times larger than the original particles. Therefore, they cannot be used directly for coloring and must be dispersed. Besides performance requirements such as hue, tinting strength, hiding power, and various resistances, the dispersibility of pigments directly affects important quality indicators such as color strength, fineness, and gloss of the produced inks and coatings. Good dispersion can also shorten grinding time in coating production. For large-scale dispersion, dispersion tests are generally required first. Existing pigment dispersion tests separate the dispersion and coloring collection stages, requiring manual material transfer. Dispersed pigment particles are prone to remain in the equipment cavity or spill during transfer, making complete collection difficult and leading to significant deviations between test results and actual dispersion effects.

[0036] Therefore, such as Figure 1 and Figure 2 The figure shown illustrates a pigment dispersion testing machine proposed in this invention, comprising: a base 400, an extrusion device 100, a heating device 200, and a collecting device 300. The extrusion device 100 is disposed on the base 400 and includes a feed hopper 120, a drive assembly, and an extrusion tube 130. The feed hopper 120 is located at the input end of the extrusion tube 130 and is used to input pigment. The feed hopper 120 has an inverted conical structure, is made of stainless steel, and has a smooth inner wall to facilitate pigment flow. The drive assembly is used to disperse the pigment and outputs it through the output end of the extrusion tube 130. The heating device 200 is disposed at the output end of the extrusion tube 130 and is used to melt the pigment. The collecting device 300 is detachably connected to the output end of the heating device 200 for easy disassembly, cleaning, and replacement. The collecting device 300 includes a fan 310 and a color developing strip 320. The fan 310 is used to blow the pigment from the heating device 200 to the color developing strip 320 to produce color. After the extrusion device 100 disperses the pigment, the pigment is melted by the heating device 200. The color developing strip 320 is connected to the heating device 200, and the molten pigment is blown into the color developing strip 320 by the blower 310 for collection and coloring. The pigment can be collected and colored without manual transfer from dispersion to collection, achieving a high degree of automation. This avoids problems such as loss, contamination, and changes in state caused by manual transfer of pigment, improving the collection rate of pigment dispersion and thus enhancing the accuracy and reliability of the experiment.

[0037] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the collecting device 300 includes a collecting roller 410, which is positioned above the heating device 200. A color-developing strip 320 is wound around the collecting roller 410 and is also positioned above the heating device 200. When the pigment is blown upwards by the fan 310 to the color-developing strip 320, the airflow from the fan 310 causes the pigment to be blown onto the color-developing strip 320. Under the influence of gravity, the pigment can be evenly spread on the surface of the color-developing strip 320, avoiding uneven distribution or splashing of the pigment on the color-developing strip 320 due to a single airflow action. This ensures full contact between the pigment and the color-developing strip 320, improving the accuracy and stability of the color development effect.

[0038] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, two conveying rollers 420 are arranged on the upper side of the heating device 200, and the two conveying rollers 420 are positioned above the collecting roller 410. The color developing strip 320 extends from the collecting roller 410 to the space between the two conveying rollers 420. The two conveying rollers 420 have the same diameter, and the color developing strip 320 passes between the two conveying rollers 420. The conveying rollers 420 rotate to move the color developing strip 320 toward the heating device 200, thereby switching the color developing area of ​​the color developing strip 320.

[0039] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, two guardrails 430 are provided on the side of the conveyor roller 420 facing the heating device 200. The upper end of the guardrail 430 is rotatably fixed to the mounting base 440. The relative distance between the two guardrails 430 gradually increases towards the color developing strip 320, and the color developing strip 320 is placed between the two guardrails 430. The gradually increasing opening structure can constrain the color developing strip 320. When the pigment is sprayed upward under the action of the fan 310, the color developing strip 320 swings under the action of the wind force, and the inclined curved surface of the guardrail 430 can prevent the color developing strip 320 from falling off.

[0040] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the base 400 is connected to a mounting base 440, which includes a longitudinally arranged bracket and two transversely arranged mounting plates. The conveyor roller 420 is placed between the two mounting plates. A screw drive mechanism 441 is provided between the mounting base 440 and the conveyor roller 420 to adjust the distance between the two conveyor rollers 420, thereby adapting to color developing strips 320 of different thicknesses and enhancing the equipment's versatility. Screw drive mechanisms 441 are provided at both ends of the conveyor roller 420, allowing independent adjustment of both ends.

[0041] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the mounting base 440 is provided with a connecting groove 451, which extends horizontally. The side wall of the guardrail 430 is provided with connecting holes. The guardrail 430 is fixed to the connecting groove 451 by fasteners, and its position can be adjusted along the extension direction of the connecting groove 451. It should be noted that the connecting holes are spaced along the length of the guardrail 430. The guardrail 430 can rotate around the end facing the conveyor roller 420 as a fulcrum, thereby allowing the connecting holes at different positions to engage with the connecting groove 451, thus changing the tilt angle of the guardrail 430. The tilt angle of the guardrail 430 can be adjusted according to different types of color-developing strips 320 or different working requirements, enhancing the flexibility and versatility of the equipment.

[0042] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the drive assembly includes a drive motor 110 and a screw. The screw is placed inside the extrusion tube 130. Under the action of the drive motor 110, the drive motor 110 connects to and drives the screw to rotate. The screw stirs, shears, and mixes the pigment entering the extrusion tube 130, achieving full dispersion of the pigment. The dispersed pigment is then output through the output end of the extrusion tube 130. The side of the screw near the feed hopper 120 has an equidistant thread, while the side near the heating device 200 has a gradually changing pitch thread. The equidistant pitch can generate a stable axial thrust. When the pigment enters the extrusion tube 130, it can be pushed forward at a constant speed, avoiding pigment accumulation or blockage. When the pigment enters the gradually changing pitch section, as the pitch decreases, the degree of compression between the pigment and the tube wall gradually increases. At the same time, the shearing force generated by the rotation effectively disperses the agglomerated pigment particles, further promoting mixing between pigment particles and improving dispersion uniformity.

[0043] According to some embodiments of the colorant dispersion tester of this utility model, the color developing strip 320 has a sleeve structure and is a white sleeve. The colorant can be blown into the sleeve by the fan 310 to develop color, and it is not easy to leak out. When the display strip is inflated by the fan 310, it can be restricted in position by the guardrail 430 to prevent deviation.

[0044] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the colorant dispersion testing machine includes a controller 500, which is wired to the heating device 200, the extrusion device 100, and the fan 310. The controller 500 can adjust the operating parameters of the heating device 200, the extrusion device 100, and the fan 310 to match. The operator only needs to input the operating parameters, and the system can automatically complete the entire process from start-up, operation to shutdown, reducing manual intervention and human error.

[0045] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the controller 500 is equipped with multiple ammeters 510, which are electrically connected to the heating device 200, the extrusion device 100, and the fan 310, respectively. The ammeters 510 are used to monitor the operating current. The ammeters 510 can provide real-time feedback on the operating current data of each device, allowing operators and maintenance personnel to intuitively understand the equipment's operating status. Understandably, the controller 500 is also equipped with a power switch and an emergency stop button. Operators can power the controller 500, heating device 200, extrusion device 100, fan 310, and other components by turning on the power switch, putting the equipment into standby or running state. In the event of a sudden dangerous situation during equipment operation, such as pigment leakage, severe abnormal vibration of components, or accidental contact with the equipment, operators can immediately press the emergency stop button to instantly cut off all power to the equipment, ensuring personnel safety.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
