Technical Field

[0001] The utility model relates to the technical field of ink production grinding, in particular to an ink dispersing and grinding device. Background Art

[0002] Ink dispersion grinding is an important link in the ink manufacturing process. Its main purpose is to evenly disperse the pigment in the binder to form a stable suspended dispersion so as to achieve satisfactory results on the machine used during printing.

[0003] In the process of dispersion and grinding, the pigment aggregates first begin to wet, then break into small particles, that is, the aggregates are separated. Then, the air on the surface of the pigment particles is replaced by the binder, that is, the water or air adsorbed on the surface of the pigment particles is replaced by the wetting medium, so that the wetting medium is attached to the surface of the pigment particles.

[0004] Different ink materials require different fineness when dispersed and ground. In the prior art, the ink material is generally dispersed and ground continuously until it is ground to the required particle size. However, the grinding device in the prior art is difficult to adjust the distance between the grinding tools, resulting in a longer time required to grind the ink material, which leads to the problem that the manufacturing efficiency of the ink material production is difficult to improve.

[0013] In summary, the utility model includes at least one of the following beneficial technical effects:

[0014] 1.

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Example:

[0024] Reference Figure 1-Figure 3 The utility model discloses an ink dispersion grinding device, including a bracket 1 and a collecting tank 2, the collecting tank 2 is movably connected to the bracket 1, a grinding outer cylinder 3 is arranged at the upper end of the bracket 1, a grinding cone 4 is arranged inside the grinding outer cylinder 3, a driving motor 5 is arranged on the top of the grinding cone 4, a driving gear plate 6 is arranged on one side of the driving motor 5, and a height adjustment mechanism 7 is arranged at the upper end of the grinding outer cylinder 3.

[0025] In this embodiment, when in use, the ink raw material to be ground is put into the interior of the device from the top of the grinding outer cylinder 3, and the grinding cone 4 is rotated by driving the motor 5, and the material is ground by the rotation of the grinding cone 4. The height of the grinding cone 4 is controlled by the height adjustment mechanism 7, and the distance between the outer wall of the grinding cone 4 and the inner wall of the grinding outer cylinder 3 is adjusted to achieve the effect of enabling the grinding device to grind materials with different particle diameters. In addition, since the grinding cone 4 can rotate during the grinding process, the ink material is continuously moved, thereby effectively dispersing the ink material during the crushing process.

[0026] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the inner cylinder wall of the grinding outer cylinder 3 is conical.

[0027] In this embodiment, the tapered barrel wall can form an angle with the outer wall of the grinding cone 4, so as to clamp the ink block, thereby achieving the purpose of improving the grinding efficiency.

[0028] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the grinding cone 4 is composed of two conical cylinders connected up and down, and the taper of the conical cylinder at the bottom is equal to the taper of the inner cylinder wall of the grinding outer cylinder 3, and the taper of the conical cylinder at the upper end is smaller than the taper of the inner cylinder wall of the grinding outer cylinder 3.

[0029] In this embodiment, since the grinding cone 4 is composed of two tapered cylinders connected to each other, and the taper of the upper tapered cylinder is smaller than the taper of the inner cylinder wall of the grinding outer cylinder 3, the outer wall of the upper tapered cylinder and the inner wall of the grinding outer cylinder 3 form an angle to facilitate clamping the ink block, thereby effectively improving the efficiency of ink grinding. Moreover, by setting the taper of the tapered cylinder at the bottom to be the same as the taper of the inner cylinder wall of the grinding outer cylinder 3, the distance between the outer wall of the bottom tapered cylinder and the inner wall of the grinding outer cylinder 3 is the same, thereby achieving the purpose of controlling the grinding degree in the process of grinding the ink block, and being able to disperse the ink powder during the rotation process.

[0030] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the bottom diameter of the grinding cone 4 is equal to the bottom diameter of the inner wall of the grinding outer cylinder 3 .

[0031] In this embodiment, since the bottom diameter of the grinding cone 4 is the same as the bottom diameter of the inner wall of the grinding outer cylinder 3, the conical cylinder at the bottom side can be closely attached to the grinding outer cylinder 3, thereby achieving the effect of improving the fineness of the grinding of the ink material.

[0033] In this embodiment, by rotating the driving worm 74, the driving worm wheel drives the adjusting gear 72 to rotate, and the adjusting gear 72 drives the driving tooth plate 6 to control the driving motor 5 to move up and down. Since the grinding cone 4 is connected to the motor shaft of the driving motor 5, the height of the grinding cone 4 is adjusted during the up and down movement of the driving motor 5, thereby achieving the effect of changing the grinding accuracy of the device. Moreover, since the driving worm wheel 73 cannot drive the driving worm 74 to move, the problem of position change of the driving motor 5 and the grinding cone 4 due to gravity is avoided.

[0034] In a further preferred embodiment of the present invention, Figure 1-3 As shown, sliding guide rails 8 are provided on both sides of the driving motor 5 , and support rods 9 fixedly connected to the grinding outer cylinder 3 are provided inside the sliding guide rails 8 .
