Description

Technical Field

[0001] The invention belongs to the technical field of ink manufacturing, and particularly relates to a pigment grinding device for ink manufacturing. Background Art

[0002] The pigment grinding device for ink manufacturing is a device specially used for efficiently grinding and dispersing a mixture of pigments and solvents. It applies shearing and extrusion effects to the material through multiple grinding rollers with different rotation speeds, so that the pigment particles are subjected to strong mechanical effects in the narrow gap between the rollers, thereby achieving uniform dispersion of fine pigment particles. Finally, the ground fine pigment particles are scraped off the roller surface and collected in the discharge trough for subsequent processing or direct use.

[0003] The existing pigment grinding device for ink manufacturing uses three grinding rollers with different rotation speeds to shear and squeeze the mixture of pigment and solvent, so that it is subjected to strong mechanical action in the narrow gap between the rollers, thereby achieving efficient grinding and dispersion, and finally scraping the ground fine pigment particles from the roller surface and collecting them in the discharge trough. However, since the ground pigment is relatively viscous, in order to avoid it taking a long time on the discharge plate to flow and discharge, affecting production efficiency, personnel need to manually use a scraper to scrape the pigment on the discharge plate to achieve rapid discharge, and the discharge plate is mostly fixed. When the discharge plate abuts against the grinding roller, The inevitable wear and tear during the friction process will cause a gap between the two, resulting in incomplete scraping. Frequent manual intervention is required to scrape off the pigment adhering to the discharge plate, which increases labor intensity and time costs and reduces overall production efficiency. Manual scraping may result in uneven scraping or omissions, affecting the quality consistency of the final product. The gap between the discharge plate and the grinding roller caused by wear will result in incomplete scraping, leaving some pigment residual, which not only affects the cleanliness but may also contaminate the next batch of products. In order to avoid this situation, operators need to replace or repair them regularly, increasing maintenance costs. Summary of the invention

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] First, the control panel is used to control the motor to start running, and the output shaft drives the grinding roller to rotate. Then, the pigment to be ground is added to the grinding roller on the far right. Then, the pigment is brought to the grinding roller in the middle after being ground by the rotation of the grinding roller and is brought to the grinding roller on the left after being ground with the grinding roller. Then, it is scraped off by the discharge plate on the far left grinding roller and collected inside the discharge plate. Then, the personnel controls the motor to start running two through the control panel, so that the connecting plate on the rotating seat and the scraper at the lower end move to the left, and the ground pigment is scraped from the discharge plate to the inside of the collection bucket. Then, the control panel is used to control the electric push rod to start running one, and the telescopic end It can drive the scraper to move upward, and then control the motor 2 to run through the control panel. After the plate is reset, the electric push rod 1 is controlled through the control panel to make the scraper abut against the discharge plate, so as to scrape and brush the paint on the discharge plate back and forth. When the discharge plate abuts against the leftmost grinding roller, the resilience of the spring can ensure that the discharge plate can continue to abut against the leftmost grinding roller even after wear, so as to ensure that the paint on the grinding roller is scraped off and collected on the discharge plate. An automatic scraping mechanism is provided to scrape the paint on the discharge plate back and forth for rapid discharge, and the discharge plate is provided with a compensation component that can abut against the grinding roller to scrape the material even after the discharge plate is worn.

[0013] Thirdly, by rotating the handwheel, the screw can be driven to rotate, and then the grinding rollers on the sliding blocks on both sides can be driven to move to the left, thereby changing the distance with the leftmost grinding roller to achieve control of the pigment grinding particle size, which greatly improves the flexibility of the grinding device.

[0014] Fourthly, the paint ground on the grinding roller can be limited by the scraping and brushing limit plates on both sides to prevent it from running off the track. When the paint grinding is finished and needs to be cleaned, the collection box is taken out from the inside of the grinding box, and then the control panel is used to control the motor three to run, thereby driving the scraping and brushing limit plates on the sliding plate to scrape the paint on the grinding roller, and cooperate with the external water pipe to flush the scraped raw materials into the grinding box for collection. Then, the control panel can be used to control the solenoid valve to be opened, so that the water mixed with the paint can be discharged from the inside of the liquid outlet pipe.
