Grinding roller of high-dispersion three-roller machine for conductive slurry production

Abstract

A grinding roller for a high-dispersion three-roller machine for the production of conductive paste proposed by the present invention includes a roller main body, a liquid inlet and outlet sleeve, a rotating end and a connecting plate. The liquid outlet and the liquid outlet are always connected with the cooling liquid channel, and the liquid inlet and outlet sleeves are rotatably connected with the liquid inlet and outlet shafts at the rotating end through the limit sleeve, and are sealed by the sealing ring in the sealing groove. The invention has a simple structure and a reasonable design. When the grinding roller When the cylinder rotates, the liquid inlet and outlet sleeves do not rotate accordingly, and the liquid inlet and outlet are always connected with the cooling liquid channel under the action of the liquid inlet slot and the liquid outlet slot. The sealing is good, the cooling liquid is not easy to leak, and the cooling The liquid channel adopts an S-shaped design, the delivery of the cooling liquid is smoother, and the delivery area of ​​the cooling liquid is relatively comprehensive and accurate. The roller cools down quickly and is not prone to thermal deformation. Furthermore, when grinding and dispersing the conductive paste, it can improve the grinding and dispersing effect of the conductive paste, prolong the continuous working time of the three-roller machine, and improve the grinding and dispersing efficiency of the conductive paste.

technical field [0001] The invention relates to the field of conductive paste production, in particular to a grinding roller for a high-dispersion three-roller machine capable of improving the dispersion effect of conductive paste. Background technique [0002] A solar cell is a semiconductor device that converts solar energy into electrical energy. Under the condition of light, a photogenerated current will be generated inside the solar cell, and the electrical energy can be output through the electrodes. [0003] As the main raw material for solar cells—solar conductive paste, its quality directly affects the quality of the produced solar cells.

Problems solved by technology

[0004] In the production process of solar conductive paste, there is an important process, which is the grinding and dispersing process; usually, enterprises mostly use three-roll machines (three-roll mills, three-roll dispersing machines) to grind and disperse solar conductive paste , however, the general three-roll machine often cannot work for a long time. The main reason is that due to the grinding and dispersion of the slurry between the rollers for a long time, it is easy to cause the overheating of the rollers, and the overheating of the rollers is easy. This will cause thermal deformation of the roller, which will seriously affect the effect of dispersing and grinding. It needs to be stopped for cooling in stages, which will greatly affect the effect and efficiency of dispersing and grinding.
