Abstract
The utility model relates to coating processing equipment, and discloses a three-roll grinder, which comprises a rack, wherein a grinding and mixing space is arranged above the rack; one end of the mixing space is provided with a discharge plate which tilts downwards; three grinding rolls with parallel axes and positioned on the same plane are arranged in the mixing space; the external diameter of the middle grinding roll is less than the external diameter of the grinding rolls on the two sides; and the rack is provided with a motor for driving the three grinding rolls to rotate. By using a coating processed by the three-roll grinder, a full grinding effect can be achieved, the particle size of pigment and filler is uniform, and the problem of flooding of a coating can be effectively avoided.
Description
Technical field
The utility model relates to the coating process equipment, especially relates to a kind ofly the color stuffing particle being ground uniform three-roll grinder.
Background technology
In the dry run of coating; Along with the volatilization of volatile component in the coating, can carry a part of color stuffing secretly on film, and these color stuffing particles are when being transported to the surface; What high surface area was arranged is easy to conveying than fine particle, and the corase particles that specific area is low relatively then is an impediment to motion.In addition; Ethylene glycol provides the continuous hydrophilic network structure of an expansion in dry run; The material of evaporation is diffused into film coated surface through this network structure, and when dried coating film, more hydrophilic material is tending towards rapid evaporation; Be that they are easy to diffusion and dissipation at this because they preferentially get into hydrophilic network structure.The particle diameter difference of color stuffing particle is excessive, and particle diameter distributed wide, can make that the compatibility between the color stuffing becomes very poor, and is poor with this pigment coatings formulated application property, films loose colour can take place, and causes the waste of pigment.
Summary of the invention
, particle diameter excessive for the particle diameter difference that overcomes color stuffing particle in the existing processing coating distributed and extensively caused the shortcoming of the loose colour of filming, and the utility model purpose is to provide a kind of can grind uniform three-roll grinder with the color stuffing particle.
The utility model is realized through following technical measures; A kind of three-roll grinder; Comprise frame; Frame top is provided with grinds the batch mixing space, and an end in this batch mixing space is provided with a downward-sloping reclaiming plate, is provided with parallel axes in this batch mixing space and is positioned at three mixing rolls on the same plane; The external diameter of the mixing roll of said centre is less than the external diameter of the mixing roll of two sides, and said frame is provided with the motor that three mixing rolls of transmission rotate.The three-roll grinder of the utility model reaches grinding effect through the surperficial mutual extrusion of three rollers of level and the friction of friction speed, and all inwardly rotations of the big mixing roll of two ends simultaneously can fully be ground raw material therein.
As a kind of optimal way, said motor is a variable-frequency motor.Grinding rate through the different processing of variable-frequency motor adjustment period mixing roll makes grinding more abundant.
Utilize the coating of the utility model processing can reach the grinding effect of sufficient, make color stuffing particle size even, avoid causing the problem of loose colour of filming.
Description of drawings
Fig. 1 is the sectional structure sketch map of the utility model.
The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is done further explain.
Like Fig. 1; A kind of three-roll grinder comprises frame 6, and frame 6 tops are provided with grinds batch mixing space 4; One end in this batch mixing space 4 is provided with a downward-sloping reclaiming plate 5, is provided with parallel axes in this batch mixing space 4 and is positioned at three mixing rolls 1,2,3 on the same plane; The external diameter of mixing roll 2 is less than the external diameter of inboard mixing roll 1 and outside mixing roll 3 in the middle of said, and frame 6 is provided with the variable-frequency motor 7 that three mixing rolls of transmission 1,2,3 rotate.Outside mixing roll 3 near reclaiming plate 5 turns clockwise in Fig. 1; And inboard mixing roll 1 is rotated counterclockwise with middle mixing roll 2; Thereby raw material is fully ground between inboard mixing roll 1 and outside mixing roll 3; And, make grinding more abundant through the variable-frequency motor grinding rate of 7 adjustment different processing periods.
More than be that the utility model three-roll grinder is set forth; Be used for helping to understand the utility model; But the embodiment of the utility model is not restricted to the described embodiments; Anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify, all should be the substitute mode of equivalence, be included within the protection domain of the utility model.
