Description

Technical Field

[0001] The utility model relates to the technical field of dispersion devices, in particular to a dispersion device for a three-roller machine and a three-roller machine using the dispersion device. Background Art

[0002] In the production process of conductive adhesive, the dispersion of materials by a three-roller mill is often involved. The three-roller mill includes three horizontally arranged rollers. The rotation of the rollers generates shear force between the materials, thereby achieving the effect of mixing or dispersion. The three-roller mill is often used for pretreatment of the mixed materials before entering the double planetary mixer to improve the uniformity of the mixed materials. However, the three-roller mill of the prior art often has insufficient dispersion uniformity. Although those skilled in the art have proposed that it can be improved by using a more advanced control system, the effect is still not good, and the introduction of advanced control systems leads to increased equipment costs and low economic benefits. Utility Model Content

[0003] In view of the defects in the prior art, the purpose of the utility model is to provide a dispersing device for a three-roller machine and a three-roller machine using the dispersing device.

[0004] According to a first aspect of the utility model, a dispersing device for a three-roller machine is provided, comprising an adjusting device and a first roller, a second roller and a third roller arranged horizontally, wherein the radius of the first roller, the second roller and the third roller are the same, and the adjusting device comprises a first adjusting device and a second adjusting device;

[0005] The first roller and the second roller are adjacent and rotate in opposite directions, and the first adjusting device is used to adjust the distance between the first roller and the second roller so that the distance is controlled between 1-120um; the second roller and the third roller are adjacent and rotate in opposite directions, and the second adjusting device is used to adjust the distance between the second roller and the third roller so that the distance is controlled between 1-120um;

[0006] Taking the rotation speed of the first roller as the reference speed, the rotation speed of the second roller is 3 times the rotation speed of the first roller, and the rotation speed of the third roller is 9 times the rotation speed of the first roller.

[0007] Preferably, the distance D1 between the first roller and the second roller is greater than the distance D2 between the second roller and the third roller.

[0008] Preferably, D1:D2=1.5:1.

[0009] According to a second aspect of the utility model, a three-roll mill is provided, comprising the dispersing device for a three-roll mill as described in any one of the above items.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The three-roller dispersing device provided by the utility model can provide shear force to the filler inside the material to achieve a good dispersing effect by controlling the speed difference between the rollers (i.e. controlling the rotation speed ratio of the first, second and third rollers = 1:3:9) and adjusting the roller gap, thereby improving the product quality of the conductive adhesive.

[0012] 2. The three-roller dispersing device provided by the utility model can finely adjust the roller gap between 1-120um, so most of the larger bubbles can be squeezed out in advance during the dispersing process, thereby improving the product quality of the conductive adhesive.

[0024] First Embodiment

[0025] This embodiment provides a three-roller dispersing device, such as Figure 1 As shown, the dispersing device includes an adjusting device and a first roller 1, a second roller 2 and a third roller 3 arranged horizontally, the first roller 1, the second roller 2 and the third roller 3 have the same radius, and the adjusting device includes a first adjusting device and a second adjusting device.

[0026] The first roller 1 and the second roller 2 are adjacent and rotate in opposite directions, and the first adjusting device is used to adjust the distance D1 between the first roller 1 and the second roller 2 and control the distance between them to be between 1-120um; the second roller 2 and the third roller 3 are adjacent and rotate in opposite directions, and the second adjusting device is used to adjust the distance D2 between the second roller 2 and the third roller 3 and control the distance between them to be between 1-120um. Preferably, the distance D1 between the first roller 1 and the second roller 2 is greater than the distance D2 between the second roller 2 and the third roller 3, and D1:D2=1.5:1.

[0027] Taking the rotation speed V1 of the first roller 1 as the reference speed, the rotation speed V2 of the second roller 2 is 3 times the rotation speed V1 of the first roller 1, and the rotation speed V3 of the third roller 3 is 9 times the rotation speed V1 of the first roller 1, that is, the rotation speed ratio V1:V2:V3 among the first roller 1, the second roller 2 and the third roller 3 is 1:3:9.

[0028] The three-roller dispersing device provided in this embodiment can provide shear force to the filler inside the material and achieve a good dispersing effect by controlling the speed difference between the rollers (i.e., controlling the first roller V1: the second roller V2: the third roller V3 = 1:3:9, when the speed of the first roller 1 is adjusted, the speeds of the second roller 2 and the third roller 3 are automatically adjusted in a ratio of 1:3:9) and adjusting the roller gap; and because the roller gap can be finely adjusted between 1-120um, most of the larger bubbles can be squeezed out in advance during the dispersing process, thereby improving the product quality of the conductive adhesive.

[0029] Second Embodiment

[0030] This embodiment provides a three-roll mill, including the dispersing device for the three-roll mill described in the first embodiment.
