Problems solved by technology

The problems in this structure are: 1. Since the diameters of the rollers are all the same, the grinding shear force depends on the rotational speed of the rollers, so it is difficult to increase the rotational speed difference by a large margin. For materials that are difficult to grind, the grinding effect is not good; 2. After two short times of shearing and rolling, the temperature of the material will increase, and the properties of the material will be affected. Therefore, this structure is not suitable for the grinding of materials that are sensitive to temperature growth.
However, some other materials have thermal insulation requirements during grinding, which cannot be met by this structure.
Although some grinding machines have added special heat dissipation mechanism or heat preservation mechanism to solve this problem, most of them have complex structures, which increase the preparation cost of the equipment

Embodiment 1

[0036] figure 2 and 3Shown is the overall structure diagram and operation diagram of the three rollers of the unequal diameter three-roll mill arranged in a straight line. The unequal-diameter three-roll mill includes a frame 2, an inlet roller 6, an intermediate roller 7, an outlet roller 8 and a prime mover 1, and the inlet roller 6, the intermediate roller 7, and the outlet roller 8 pass through the bearing mounting seat 5 in turn. Installed on the frame 2, one side of the discharge roller 8 is provided with a discharge roller 8 scraper 4, the blade of the discharge roller scraper 4 can be adjusted to press the discharge roller 8; the feed roller 6, the middle roller 7, the discharge roller The diameter of 8 increases step by step; the axis connection line between the feed roller 6 and the intermediate roller 7 and the axis connection line between the intermediate roller 7 and the discharge roller 8 are arranged in a straight line; the feed roller 6 , Intermediate roll 7...

Embodiment 2

[0039] Figure 4 Shown is a schematic diagram of the overall structure in which the three rollers of the unequal diameter three-roll mill are arranged in a non-line shape; Figure 5 Shown is a schematic diagram of an arrangement of three rollers. The difference from Embodiment 1 is that the axis connecting line between the feeding roller 6 and the intermediate roller 7 and the axis connecting line between the intermediate roller 7 and the discharging roller 8 are not arranged in a straight line. The unequal-diameter three-roll mill can use prime mover 1 to provide power for the feed roller 6, intermediate roller 7, and discharge roller 8, and the feed roller 6 and intermediate roller 7 are connected by gears with different transmission ratios. The intermediate roller 7 and the discharge roller 8 are connected by gears with different transmission ratios, see Figure 5 , by setting gears with different gear ratios, the linear velocity of the relative movement of the rollers is...

Embodiment 3

[0041] The unequal-diameter three-roll mill of this embodiment is more suitable for grinding materials that are more sensitive to temperature increase (such as ink and paint materials). see Figure 6 , the unequal-diameter three-roller grinder includes frame 2, feeding roller 6, intermediate roller 7, discharging roller 8 and prime mover 1, feeding roller 6, intermediate roller 7 and discharging roller 8 pass through bearing mount 5 Installed on the frame 2 in turn, one side of the discharge roller 8 is provided with a discharge roller scraper 4, the blade of the discharge roller scraper 4 can be adjusted to press the discharge roller 8; the feed roller 6, the intermediate roller 7, the discharge roller The diameters of 8 are not completely the same or completely different; the axis connecting line between the feeding roller 6 and the intermediate roller 7 and the axis connecting line between the intermediate roller 7 and the discharging roller 8 are arranged in a V shape; Am...

Abstract

The invention belongs to the technical field of grinding machines, and provides an unequal-diameter three-roller grinding machine which comprises a rack, a feeding roller, an intermediate roller and a discharging roller, wherein the diameters of the feeding roller, the intermediate roller and the discharging roller are not completely the same or are completely different; the larger the diameters of the rollers are, the higher the linear speeds of the relative movements of the roller surfaces are; the axis connecting line between the feeding roller and the intermediate roller as well as the axis connecting line between the middle roller and the discharging roller are in a V shape; the diameter of the intermediate roller is larger than that of the feeding roller and that of the discharging roller, and the diameter of the discharging roller is larger than that of the feeding roller; and or the diameter of the intermediate roller is smaller than that of the feeding roller and that of the discharging roller, and the diameter of the discharging roller is smaller than that of the feeding roller. The diameters of the three rollers are set to be different; the larger the diameters are, the higher the linear speeds of the speed surfaces are, so that the linear speed difference among the rollers can be increased, the material grinding shear force can be improved, and the grinding effect can be improved; and through the rollers arranged in a V shape and the special design of unequal diameters, materials can be subjected to heat dissipation or heat preservation in the grinding process.

Description

technical field [0001] The invention relates to the technical field of grinders, in particular to a three-roller grinder with unequal diameters. Background technique [0002] The currently known three-roll grinding machine is mainly composed of three rollers whose axes are in a straight line and arranged horizontally. For a schematic diagram of its structure, see figure 1 , and some are composed of three rollers arranged in a non-linear manner. They are characterized by three rollers of equal diameter. The material is put into the material hopper between the feeding roller and the middle roller. After the first shearing and rolling of the feeding roller and the middle roller, it is brought into the middle roller and the discharge roller by the surface of the middle roller for the second shearing. and rolling, and then flow out from the discharge roller surface through the discharge scraper. The problems existing in this structure are: 1. Since the diameters of the rollers...
