[0067] The purpose of this design is to allow for the adjustment of the size of the crushed material by setting up fixed rollers and moving rollers.

[0068] It should be noted that, compared with the existing crushing structure, in order to meet the requirements of a large crushing ratio, a two-stage crushing and crushing structure with an upper coarse crusher and a lower fine crusher is adopted, with an upper coarse crusher box and a lower fine crusher box respectively. At the same time, the rotation of the blades between the upper coarse crusher and the lower fine crusher can also achieve the effect of crushing materials simultaneously.

[0069] In this embodiment, the specific structure of the upper toothed liner plate is provided. The upper toothed liner plate 3 includes an upper fixing piece 28 and a plurality of upper toothed liner plates 25.

[0084] The upper box assembly 30 is located below the feed chamber 2 of the double-layer dispersing machine 1;

[0085] The upper fixed roller 4 and the upper movable roller 5 are arranged side by side in the upper box assembly 30;

[0086] The upper fixed roller control motor 31, the upper moving roller control motor 32 and the upper moving roller adjustment frame 33 are located outside the upper box assembly 30;

[0087] One end of the upper fixed roller 4 is connected to the power output end of the upper fixed roller control motor 31;

[0089] The purpose of this design is to adjust the distance between the upper fixed roller and the upper moving roller by setting an upper crushing roller assembly containing an upper fixed roller and an upper moving roller inside the double-layer crusher, thereby meeting the processing of raw materials of different sizes and completing coarse crushing.

[0090] It should be noted that when adjusting the size, the upper moving roller is usually adjusted by the upper moving roller adjustment frame, so that the upper moving roller can move horizontally.

[0091] Meanwhile, in this embodiment, the upper box assembly 30 is provided with an upper fixed roller connection hole and an upper movable roller connection hole, and the upper movable roller 5 can move horizontally within the upper movable roller connection hole.

The tooth length of the long blades 44 is greater than the tooth length of the short blades 43. The long blades 44 and short blades 43 are arranged alternately.

[0098] The purpose of this design is that, under normal circumstances, the upper fixed roller and the upper moving roller are crushing rollers with the same structure, only the upper fixed roller and the upper moving roller are different based on the connected motor.

[0099] Meanwhile, both stages of crushing rollers use independent drives, so a failure in the drive of either roller will not affect normal production in a short period of time.

[0100] Furthermore, by setting up staggered short and long blades to form a staggered biting structure, the problem of large pieces of material not being able to be bitten in properly is effectively solved.

[0108] The purpose of this design is to adjust the distance between the lower fixed roller and the lower moving roller by setting a lower crushing roller assembly containing a lower fixed roller and a lower moving roller in the double-layer crusher, thereby meeting the processing of raw materials of different sizes and completing fine crushing.

[0109] It should be noted that when adjusting the size, the lower moving roller adjustment frame is usually used so that the lower moving roller can move horizontally.

[0110] Meanwhile, in this embodiment, the lower housing assembly 50 is provided with a lower fixed roller connection hole 57 and a lower movable roller connection hole 56, and the lower movable roller 5 can move horizontally within the lower movable roller connection hole 56.

[0111] The purpose of this design is to reduce heat conduction to the left and right transmission devices by setting a heat-resistant sealing ring, thereby effectively reducing the heat transferred to the bearing housing.

[0112] In this embodiment, both the lower fixed roller 6 and the lower movable roller 7 include a second main shaft 58, a second positioning sleeve 60 and a second adjusting ring 61.

[0113] The second positioning sleeve 60 is connected to the lower fixed roller control motor 31 or the lower moving roller control motor 32;

[0114] The second adjusting ring 61 wraps around the outer periphery of the second main shaft 58 and is located at the edge of the second crushing cutter tooth assembly.

[0115] Meanwhile, the second crushing cutter tooth group includes a hexagonal eight-tooth blade 62, and the hexagonal eight-tooth blade 62 has a hexagonal roller main shaft 63 in the middle, and the roller main shaft 63 can be sleeved on the second main shaft 58. Eight short teeth 64 are arranged on the outer periphery of the roller main shaft 63.

[0116] The purpose of this design is to use hexagonal, eight-tooth blades with eight teeth in the circumferential direction. The roller main shaft and the blades adopt a hexagonal structure. The fine crushing blades are installed at an angle to the main shaft to form an interlaced structure. Only two to three pairs of teeth are in contact with the material, which effectively reduces the crushing load on the main shaft and helps to distribute the load evenly on the roller. At the same time, it achieves the differential crushing effect that would otherwise require the two crushing main shafts to be configured with different speeds.

[0117] Meanwhile, both stages of crushing rollers use independent drives, so a failure in the drive of either roller will not affect normal production in a short period of time.

[0118] It should be noted that in actual use, the diameter of the hexagonal eight-tooth cutting tool can be 400mm.

[0119] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
