[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0028] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, and the spatial relative descriptions used herein will be interpreted accordingly.

[0029] The central column of the related disc-type koji-making equipment is a monolithic structure extending in the axial direction. Therefore, the bearing between the disc and the central column needs to be a non-standard, custom-made split-half bearing. Thus, during bearing installation, the two split-half bearings are joined together from opposite sides of the central column.

[0030] The inventor found in the research process that the split bearing is very high in cost because it needs to be customized. Moreover, because the two split bearings need to be butted, the butted part is prone to uneven mounting, affecting the flatness of the bearing surface, and thus the installation is difficult.

[0031] To solve the problem, the inventor proposes, through in-depth research, that the center column is provided as two split upper and lower segments, so that a standard integrated slewing bearing can be used to replace the split bearing in the related art, thereby greatly reducing the processing cost of the bearing and the cost of the disc starter device. Moreover, the standard integrated slewing bearing has good integrity and high surface flatness, so the installation difficulty is greatly reduced compared with the split bearing that needs to be butted and mounted.

[0032] The structure and working process of the disc starter device according to the embodiment of the present application will be described in detail below. Figures 1 to 4 The structure and working process of the disc starter device according to the embodiment of the present application will be described in detail below.

[0033] With reference to Figures 1 to 4 The disc starter device according to the embodiment of the present application comprises a disc 30, a center column, and a bearing 40. The disc 30 has a center hole. The center column is fixedly arranged in the center hole. The center column comprises an upper segment center column 10 and a lower segment center column 20 which are arranged in the axial direction. The bearing 40 comprises an inner ring 401 and an outer ring 402. The inner ring 401 is a circumferentially closed integrated annular structure. The outer ring 402 is a circumferentially closed integrated annular structure. The inner ring 401 is connected with the lower segment center column 20. The outer ring 402 is connected with the disc 30, so that the disc 30 rotates around the center column.

[0034] The disc starter device according to the embodiment of the present application arranges the center column as the upper segment center column 10 and the lower segment center column 20 which are arranged in the axial direction, that is, changes the integrated center column in the related art into a split center column. Thus, when the bearing is installed, the bearing can be directly installed between the upper segment center column 10 and the lower segment center column 20, without being split and mounted from both sides of the center column. Therefore, a standard integrated bearing can be used, that is, the inner ring 401 of the bearing 40 is a circumferentially closed integrated annular structure, and the outer ring 402 is also a circumferentially closed integrated annular structure, reducing the customization and processing cost of the split bearing and thereby reducing the cost. Moreover, the standard integrated bearing has good integrity and high surface flatness, and the installation difficulty is greatly reduced compared with the split bearing that needs to be split and mounted. Therefore, the disc starter device according to the embodiment of the present application has great improvement in both installation and cost.

[0035] As Figure 4As shown, the bearing 40 of the disc-shaped koji-making device in this embodiment of the present invention is a standard bearing with an integral structure. Here, "integral structure" means that it does not require mating during installation; the bearing 40 itself is a single unit. It includes an inner ring 401 and an outer ring 402. Figure 4 The diagram shows a partial structure of bearing 40. The inner ring 401 is a one-piece annular structure, and the outer ring 402 is also a one-piece annular structure.

That is, the upper central column 10 and the lower central column 20 are not only separately arranged, but also have an axial gap between them. This axial gap provides space for bearing maintenance.

[0037] In this embodiment of the present invention, the inner ring 401 of the bearing 40 is connected to the lower central column 20. In some embodiments, reference... Figure 1 The bearing 40 is mounted above the lower central column 20. The disc-forming device also includes a height positioning structure 70 disposed between the inner ring of the bearing 40 and the lower central column 20. The height positioning structure 70 is used to adjust the height of the bearing 40 relative to the lower central column 20.

[0038] The bearing 40 is positioned above the lower central column 20. Specifically, the inner ring 401 of the bearing 40 is connected to the lower central column 20. The height of the inner ring 401, i.e., the entire bearing 40, is adjusted by setting a height positioning structure 70 between the inner ring 401 and the lower central column 20. Figure 1 As shown, the height positioning structure 70 is disposed on the top surface of the lower central column 20, and the inner ring 401 of the bearing 40 is disposed above the height positioning structure 70. Therefore, the height of the height positioning structure 70 can adjust the distance between the bearing 40 and the lower central column 20. Specifically, the height of the height positioning structure 70 is adjustable to adjust the height of the bearing 40 according to different needs.

[0039] In some embodiments, the height positioning structure 70 includes a pad. Different thicknesses of pads can be selected to adjust the height of the bearing 40.

[0042] Specifically, as shown in Figure 3 the lower center column 20 comprises a lower center column body 21 and a lower conical section 22 arranged outside the lower center column body 21. The top surface of the lower center column body 21 is higher than that of the lower conical section 22, so that the lower center column body 21 has a top end portion protruding in height from the top end portion of the lower conical section 22. The limiting structure 60 has an annular abutting surface located at the inner radial ring, and when installed, the annular abutting surface of the limiting structure 60 abuts on the outer side surface of the top end portion and is placed on the height positioning structure 70. The radial outer edge of the limiting structure 60 is configured with a clamping groove, as shown in Figure 1 the inner ring of the bearing 40 is clamped in the clamping groove, so that the clamping groove limits the radial position of the bearing 40 to prevent the bearing 40 from being displaced in the radial direction, thereby improving the positional stability of the bearing.

[0043] In the embodiment of the utility model, the lower center column 20 is provided with the lower center column body 21 and the lower conical section 22, so that the lower conical section 22 is used to bear the bearing 40.
