Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model.

[0031] The embodiments of the utility model will be described below in combination with Figures 1 to 6 .

[0032] According to the embodiment of the utility model, on the one hand, a dry granulator pressure roller dismounting tool is provided, which comprises: a round sleeve 10 and a connecting nut 20. The round sleeve 10 comprises a positioning portion 11 and a guide portion 12, the guide portion 12 is connected with the positioning portion 11, the outer diameter of the guide portion 12 is larger than the outer diameter of the positioning portion 11, the guide portion 12 is adapted to slide against the outer hole 31 of the pressure roller 30, a first cavity 121 is formed in the guide portion 12, a second cavity 111 is formed in the positioning portion 11, the first cavity 121 and the second cavity 111 are communicated; at least part of the connecting nut 20 is arranged in the second cavity 111, the connecting nut 20 is connected with the positioning portion 11, the connecting nut 20 is adapted to be detachably connected with the rotating shaft 40, and the thread center line of the connecting nut 20 is arranged in coincidence with the axis of the round sleeve 10.

[0033] When the pressure roller 30 needs to be dismounted, the connecting nut 20 is connected with the rotating shaft 40, the dry granulator pressure roller dismounting tool is used to limit the pressure roller 30 to rotate on the guide portion 12 and move along the axis of the round sleeve 10, so that the inner hole 32 of the pressure roller 30 is coincided with the axis of the rotating shaft 40, thereby solving the problem that the pressure roller 30 is stuck on the rotating shaft 40.

[0034] Specifically, part of the connecting nut 20 is arranged in the second cavity 111, and part of the connecting nut 20 is arranged in the first cavity 121.

[0035] Specifically, please refer to Figure 3 The pressure roller 30 is formed with an outer hole 31 and an inner hole 32, the outer hole 31 is communicated with the inner hole 32, and the axis of the outer hole 31 and the inner hole 32 is arranged in coincidence.

[0036] Specifically, the guide portion 12 is connected with the positioning portion 11, the axis of the guide portion 12 and the positioning portion 11 is arranged in coincidence, the outer diameter of the guide portion 12 is slightly smaller than the inner diameter of the outer hole 31 of the pressure roller 30, and the outer diameter of the guide portion 12 is larger than the outer diameter of the positioning portion 11.

[0037] It is worth noting that the outer diameter of the guide portion 12 is larger than the outer diameter of the positioning portion 11, which facilitates the outer hole 31 of the pressure roller 30 to quickly pass through the positioning portion 11 and reduces the friction between the positioning portion 11 and the outer hole 31 of the pressure roller 30.

[0038] It should be noted that when the connecting nut 20 is connected with the rotating shaft 40, the thread center line of the connecting nut 20 is arranged in coincidence with the axis of the round sleeve 10, at this time, the axis of the rotating shaft 40 is coincided with the axis of the round sleeve 10; at the same time, the guide portion 12 is in sliding abutment with the outer hole 31 of the pressure roller 30, at this time, the axis of the guide portion 12 is coincided with the axis of the outer hole 31 of the pressure roller 30, therefore, the inner hole 32 of the pressure roller 30 is coincided with the axis of the rotating shaft 40.

[0039] It can be understood that when the guide part 12 is in sliding abutment with the outer hole 31 of the compression roller 30, according to the positioning rule, the compression roller 30 has only two degrees of freedom, that is, the compression roller 30 can only move along the axis of the compression roller 30 or rotate around the axis.

[0040] In a further embodiment, as shown in Figure 1 , the positioning part 11 is provided with two, and the two positioning parts 11 are respectively connected with the two ends of the guide part 12, and the connecting nut 20 is provided with two, and the two connecting nuts 20 are respectively arranged corresponding to the two positioning parts 11.

[0041] It should be noted that the thread size of the connecting nut 20 can be set according to actual needs.

[0042] It is worth noting that by providing two connecting nuts 20, it is convenient to make one dry granulator compression roller dismounting tool suitable for a plurality of different sizes of rotating shafts 40.

[0043] In a further embodiment, as shown in Figure 1 , the outer wall of the guide part 12 and the outer wall of the positioning part 11 are connected in a tapered transition.

[0044] It should be noted that if the outer wall of the guide part 12 and the outer wall of the positioning part 11 are not provided with a transition structure, when the outer hole 31 of the compression roller 30 is moved from the positioning part 11 to the guide part 12, the compression roller 30 is easy to directly knock against the outer wall of the guide part 12, which is easy to damage the compression roller 30.

[0045] It is worth noting that the outer wall of the guide part 12 and the outer wall of the positioning part 11 are connected in a tapered transition, so that the sliding between the compression roller 30 and the dry granulator compression roller dismounting tool is smooth.

[0046] In a further embodiment, the thread directions of the two connecting nuts 20 are left-handed thread and right-handed thread respectively.

[0047] It is worth noting that the thread directions of the two connecting nuts 20 are left-handed thread and right-handed thread respectively, and are respectively matched with the upper and lower rotating shafts 40 of the dry granulator.

[0048] In a further embodiment, as shown in Figure 1 , the two connecting nuts 20 are symmetrically arranged in the circular sleeve 10.

[0049] In a further embodiment, as shown in Figure 1 and Figure 2 , a through hole 13 is formed in the guide part 12, the through hole 13 penetrates the first cavity 121, and the through hole 13 is formed between the two connecting nuts 20.

[0050] It is worth mentioning that when connecting the dry granulator roller dismounting tool and the rotating shaft 40, a booster rod can be installed on the perforation to facilitate the rapid rotation of the dry granulator roller dismounting tool.

[0051] In further embodiments, as shown in Figure 1 , the connecting nut 20 comprises a connecting structure 21 and a main body structure 22, the connecting structure 21 connects the main body structure 22 and the positioning part 11, and threads are arranged on the main body structure 22.

[0053] It is worth mentioning that in other alternative embodiments, those skilled in the art can also detachably connect the connecting nut 20 and the positioning part 11, such as clamping, etc., so as to facilitate the replacement of the connecting nut 20.

[0054] In further embodiments, the length of the round sleeve 10 is greater than the depth of the inner hole 32 of the roller 30.

[0055] It is worth mentioning that when the length of the round sleeve 10 is greater than the depth of the inner hole 32 of the roller 30, when the roller 30 is installed with the rotating shaft 40, it is ensured that after the connecting nut 20 is connected with the rotating shaft 40, part of the structure of the round sleeve 10 extends into the outer hole 31 of the roller 30, facilitating the guided installation of the roller 30.

[0056] Using the dry granulator roller dismounting tool of the present embodiment, taking the installation of the roller 30 and the rotating shaft 40 as an example, please refer to Figures 4 to 6 , it is worth mentioning that in Figures 4 to 6 , in order to better show the relative position between the roller 30 and the rotating shaft 40, the roller 30 is shown in a cross-sectional view structure; in the use state shown in Figure 4 , the connecting nut 20 is threadedly connected with the rotating shaft 40, and the outer hole 31 of the roller 30 is sleeved on the positioning part 11; in the use state shown in Figure 5 , the roller 30 slides to the right side of the drawing direction, the outer hole 31 of the roller 30 slides and abuts against the guiding part 12, and the rotating shaft 40 gradually enters the inner hole 32 of the roller 30; in the use state shown in Figure 6 , the roller 30 and the rotating shaft 40 are installed in place, the connecting nut 20 is rotationally separated from the rotating shaft 40, and the dry granulator roller dismounting tool is removed from the outer hole 31 of the roller 30.

[0057] It is worth mentioning that the dismounting process of the roller 30 and the rotating shaft 40 is opposite to the installation process, and therefore will not be described here.

[0058] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the present application.
