For another example, the third flange 61 may be connected to the cutting frame 1 by pins, stud nuts, or the like. For another example, the second annular boss 62 may be a clearance fit with the second inner bore 12 in addition to the transition fit, but the clearance fit may cause a decrease in the accuracy of the fit. For another example, although the inner circumferential surface of the second annular boss 62 is flush with the second eccentric hole 63 in the above-described embodiment, it is not limited thereto, and one skilled in the art may set the inner circumferential surface of the second annular boss 62 to have an inner diameter larger than or smaller than that of the second eccentric hole 63.
For another example, although the motor base 7 is described above in connection with the first flange 71, the second flange 72, the connecting structure 73 and the first annular boss 75, the specific structure of the motor base 7 is not constant, and may be adjusted by those skilled in the art. For example, the motor mount 7 may comprise only one flange, which is connected to both the cutting frame 1 and the drive motor 8; for another example, the first flange 71 may omit the first annular boss 75; for another example, the first flange 71 may be connected to the cutting frame 1 by pins, stud nuts, or the like. For another example, the connecting structure 73 may be a plurality of arc plates besides the connecting column, and a hollow is formed between the adjacent arc plates, or the connecting structure 73 is a connecting sleeve, and at least one opening is formed on the outer peripheral surface of the connecting sleeve, so as to reduce the assembly difficulty of the motor. For another example, the number and arrangement of the connection posts can be adjusted as required by those skilled in the art. For another example, the first annular boss 75 and the second inner hole 12 may be clearance fit in addition to the transition fit, but the clearance fit may cause a decrease in the fitting accuracy. For another example, although the inner circumferential surface of the first annular boss 75 is flush with the third eccentric hole 74 in the above-described embodiment, this is not limitative, but one skilled in the art may set the inner circumferential surface of the first annular boss 75 to have an inner diameter larger or smaller than that of the third eccentric hole 74. For another example, when the outer diameter of the second bearing housing 3 is changed, the third eccentric hole 74 may be different from the second eccentric hole 63 in size.
For another example, the first bearing housing 2 and the second bearing housing 3 are not limited to the single arrangement, and the first bearing housing 2 may be fixedly connected to the first eccentric sleeve 5 in addition to being connected to the first eccentric sleeve 5 in a sliding manner. Similarly, the second bearing box 3 may be fixedly connected to the second eccentric sleeve 6, or may be connected to the second eccentric sleeve 6 and the motor base 7 in a push-pull manner, or may be fixedly connected to the motor base 7.
For another example, the pull rod 9 and the locking assembly 10 described above may be replaced by other locking means commonly used in the art, as long as the main roller 4 can be locked between the first bearing housing 2 and the second bearing housing 3.
As another example, although the above embodiment is described with reference to the case where the first inner hole 11 and the second inner hole 12 are provided on the cutting frame 1 at the same time, the first inner hole 11 and the second inner hole 12 are not necessarily required, and in other embodiments, a person skilled in the art may freely select a mounting manner of the first bearing housing 2 and the second bearing housing 3, for example, at least one of the first bearing housing 2 and the second bearing housing 3 may be mounted in a major arc-shaped opening provided on the cutting frame 1 through a corresponding eccentric sleeve, or a through hole formed by a mounting bracket provided on the cutting frame 1, or the like, so long as the first bearing housing 2 and the second bearing housing 3 can be mounted in any manner.
As another example, although the present embodiment is described with reference to the case where two main rollers 4 are provided on the cutting frame 1, this is not intended to limit the scope of protection of the present application, and one skilled in the art may apply the present application to other main roller numbers of cutting assemblies, for example, to cutting assemblies having three, four or even more main roller numbers.
Of course, the alternative embodiments described above, as well as the alternative and preferred embodiments, may also be used in a cross-fit manner, thereby combining new embodiments to suit more specific application scenarios.
A possible adjustment of the wheelbase of the main roller 4 will be described next.
In a possible embodiment, when it is desired to adjust the wheelbase between the two main rollers 4, the nut of the locking assembly 10 is first unscrewed and the pull rod 9 is then removed and pulled out. The first bearing housing 2 is then pulled out by a suitable distance so that the main roller 4 loosens. Then, the main roller 4 is lifted by using the hanging belt, the main roller 4 is prevented from falling, and the first bearing box 2 is pulled out continuously until the main roller 4 can be taken out smoothly. After the main roller 4 is taken out, the coupling between the drive motor 8 and the second bearing housing 3 is removed, and then the drive motor 8 is removed.
After the main roller 4 is taken out, bolts for fastening the first eccentric sleeve 5, the second eccentric sleeve 6 and the motor base 7 are disassembled, then the first eccentric sleeve 5, the second eccentric sleeve 6 and the motor base 7 are rotated according to the wheelbase to be adjusted, and after the rotation, the first eccentric sleeve 5, the second eccentric sleeve 6 and the motor base 7 are fixed on the cutting chamber frame again. And then reinstalling the main roller 4, and finally installing the driving motor 8 and the coupling, thereby completing the wheelbase adjustment of the main roller 4.
Of course, the above specific adjustment manners are merely used to illustrate the principles of the present application, and are not intended to limit the scope of protection of the present application, and those skilled in the art may make modifications to the adjustment manners of the wheelbase of the main roller 4 without departing from the principles of the present application, so that the present application is suitable for more specific application scenarios. For example, a person skilled in the art may adjust the order of attaching and detaching the main roller 4, the first eccentric sleeve 5, the second eccentric sleeve 6, the driving motor 8, and the like, or may adjust the order of adjusting the rotation of the first eccentric sleeve 5, the second eccentric sleeve 6, the motor mount 7, and the like.
The application also provides a wire cutting machine, which comprises the cutting assembly of the embodiment. Preferably, the wire cutting machine is a microtome.
By arranging the cutting assembly in the wire cutting machine, the overall cost can be reduced, and the material waste and the assembly difficulty can be reduced. Of course, the wire cutting machine may be other types of wire cutting equipment other than a slicer, such as a mortar machine, etc.
