[0047] The preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application.

In addition, the terms "first", "second", "third", and "fourth" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, in the description of the present application, "multiple" refers to at least two.

[0049] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0050] In order to solve the problem that the existing slicers use eccentric sleeves or eccentric bearing boxes to achieve adjustable wheelbase, which wastes time and manpower and leads to reduced production efficiency, the cutting assembly of the present application includes a cutting frame, a limit sleeve and a main roller assembly, and mounting holes are respectively opened on two oppositely arranged side walls of the cutting frame, each mounting hole is detachably provided with a limit sleeve, and each limit sleeve is provided with a limit hole. The main roller assembly includes a main roller and two bearing boxes respectively connected to the two ends of the main roller, and the two bearing boxes are correspondingly installed in the limit holes of the two limit sleeves.

[0051] In one embodiment, the two bearing boxes of the main roller assembly are respectively installed in two limit sleeves, and the two limit sleeves are respectively installed in the mounting holes on the two oppositely arranged side walls of the cutting frame. There are multiple types of limit sleeves, and the upper limit holes of each type of limit sleeve are opened at different positions. When the wheelbase between the main rollers needs to be adjusted, the position of the main roller is adjusted by disassembling and replacing the limit sleeves of other types. In another embodiment, a single limit sleeve is provided with multiple limit holes. When the wheelbase between the two main rollers needs to be adjusted, the position of the main roller is adjusted by disassembling the bearing box and moving it to other limit holes on the limit sleeve.

[0052] The technical solution of the present application, by providing a detachably connected limit sleeve, can adjust the wheelbase of the main roller by replacing limit sleeves of different models or providing multiple groups of limit holes on the limit sleeve. Compared with the adjustment method of the eccentric sleeve or the eccentric bearing box, the adjustment process of this solution is simpler and easier, which is beneficial to reducing the time of wheelbase adjustment and thus improving production efficiency.

[0053] See below for further reference Figures 1 to 3C , the first preferred implementation of the present application is introduced.

[0054] like Figure 1 and Figure 2 As shown, in the first preferred embodiment, the cutting assembly includes a cutting frame 1, a limiting sleeve 2, a main roller assembly 3 and a limiting flange 4.

[0055] Mounting holes 11 are respectively provided on two opposite sides of the cutting frame 1, and the mounting holes 11 are rounded rectangular holes in this embodiment. The main roller assembly 3 includes a main roller 31 and two bearing boxes 32 arranged at both ends of the main roller 31. The main roller 31 is installed between the two bearing boxes 32. The connection method between the main roller 31 and the two bearing boxes 32 is a conventional method in the field and will not be repeated in this application. The limiting sleeve 2 is correspondingly a rectangular sleeve, and the limiting sleeve 2 can be embedded in the corresponding mounting hole 11 and connected to the side wall of the cutting frame 1 through a connecting member. Among them, the connecting member can be a bolt, a threaded hole is provided on the cutting frame 1, and a through hole is provided on the edge of the limiting sleeve 2. The bolt passes through the through hole and is screwed into the threaded hole, thereby realizing the installation and fixation of the limiting sleeve 2.

[0056] See also Figure 2 and Figure 3A , a first connection hole 22 is provided on one end face of the limiting sleeve 2, a flange 321 is formed on one end of the bearing box 32 radially extending outward, a second connection hole 322 is provided on the flange 321, and the first connection hole 22 and the second connection hole 322 are connected by a fastener. Preferably, the first connection hole 22 is a threaded hole, which is provided on the outer end face of the limiting sleeve 2 (the side away from the inside of the cutting frame 1), the flange 321 is formed at the end of the bearing box 32 away from the main roller 31, the second connection hole 322 is provided on the flange 321, the second connection hole 322 is a through hole, and the fastener is a bolt, which passes through the through hole and is screwed to the threaded hole, thereby realizing the fixed connection between the bearing box 32 and the limiting sleeve 2.

[0057] Reference Figure 1 and Figure 2 , a limiting flange 4 is provided in each mounting hole 11. Specifically, the limiting flange 4 is provided at one end of the mounting hole 11 close to the inside of the cutting frame 1, and is fixedly connected to the cutting frame 1, such as being connected to the cutting frame 1 by bolts. The limiting flange 4 has a flange hole (not shown in the figure), the diameter of the flange hole is smaller than the diameter of the limiting hole 21, and the flange hole is sleeved on the bearing box 32. The flange hole on the limiting flange 4 is a circular hole. When the bearing box 32 is installed in different limiting holes 21, a limiting flange 4 with a different flange hole setting position can be used to match it. Furthermore, the flange hole extends outward to form an annular flange 41, and the annular flange 41 can be inserted into the limiting hole 21.

[0058] In this way, the end of the bearing box 32 away from the main roller 31 is connected to the outer end surface of the limit sleeve 2 by bolts, the limit flange 4 is sleeved on the end of the bearing box 32 close to the main roller 31 and the annular flange 41 is inserted into the limit hole 21 to achieve the positioning of the two ends of the bearing box 32.

[0059] See also FIG. 3A to FIG. 3CIn this embodiment, there are multiple types of limiting sleeves 2, and the limiting holes 21 on the multiple limiting sleeves 2 have the same diameter but are arranged at different positions. FIG. 3A to FIG. 3C Three types of limit sleeves 2 are shown, wherein Figure 3A The limiting sleeve 2 shown has a limiting hole 21 opened on the left side. Figure 3B The limiting sleeve 2 shown has a limiting hole 21 opened in the middle. Figure 3C The limiting hole 21 of the limiting sleeve 2 shown is opened on the right side. In this way, when the wheelbase between the main rollers 31 needs to be adjusted, the position of the main rollers 31 can be simply and conveniently adjusted by replacing the limiting sleeves 2 of different types, thereby adjusting the wheelbase between the main rollers 31.

[0060] Return to reference Figure 1 Preferably, the cutting assembly of the present application is provided with three main roller assemblies 3, and three mounting holes 11 are opened on each side wall of the cutting frame 1. A limiting sleeve 2 is installed in each mounting hole 11, and the three main roller assemblies 3 are all installed on the cutting frame 1 through the limiting sleeve 2. Among them, the two main roller assemblies 3 located at the top can be adjusted in the horizontal direction through the limiting sleeve 2, and the main roller assembly 3 located at the bottom can be adjusted in the vertical direction through the limiting sleeve 2.

[0061] The above-mentioned setting method can realize the position adjustment of the main roller 31 by replacing different types of limit sleeves 2. The adjustment method is simple and effective, which is conducive to reducing the adjustment time and improving production efficiency. The first connecting hole 22 is arranged on the outer end surface of the limit sleeve 2, which is conducive to reducing the difficulty of disassembly and assembly of the bearing box 32. By setting the limit flange 4, it is conducive to improving the positioning accuracy of the bearing box 32. The diameter of the flange hole is smaller than the diameter of the limit hole 21, which is conducive to improving the positioning accuracy of the bearing box 32 and reducing the difficulty of assembly and disassembly of the bearing box 32. The limit flange 4 is formed with an annular convex edge 41, which is conducive to improving the connection stability of the bearing box 32.

[0062] Those skilled in the art can understand that the above-mentioned configuration is only preferred. Without departing from the principles of the present application, those skilled in the art can adjust the above-mentioned configuration so that the present application is suitable for more specific application scenarios.

[0063] For example, although the above-mentioned limit sleeve 2 is connected to the side wall of the cutting frame 1 through a connecting piece, the fixing method of the limit sleeve 2 is not unique. In other embodiments, the limit sleeve 2 can also be connected to the corresponding mounting hole 11 through a clearance fit or a transition fit.

[0064] For another example, although the above embodiment is described in conjunction with the mounting hole 11 being a rectangular hole and the limiting sleeve 2 being a rectangular sleeve, the specific shapes of the mounting hole 11 and the limiting sleeve 2 are not fixed, as long as the two are adapted to each other. For example, the mounting hole 11 can also be a circular hole, an elliptical hole, a square hole, etc., and the limiting sleeve 2 can be a circular sleeve, an elliptical sleeve, or a square sleeve accordingly.

[0065] For another example, the bearing box 32 can be connected to the limiting sleeve 2 by a transition fit or a clearance fit in addition to being connected to the limiting sleeve 2 by a fastener. The fastener can be a pin in addition to a bolt. The first connecting hole 22 can be set on the outer end surface of the limiting sleeve 2 or on the inner end surface of the limiting sleeve 2, and the flange edge 321 of the bearing box 32 is correspondingly set at one end close to the main roller 31. In this case, the limiting flange 4 can be set on the outer end surface of the cutting frame 1.

[0066] For another example, the setting of the limiting flange 4 is not necessary. On the premise that the limiting sleeve 2 can position the bearing box 32, the setting of the limiting flange 4 can be omitted. In addition, on the premise of setting the limiting flange 4, the specific structural form of the limiting flange 4 is not static, and those skilled in the art can adjust it based on the application scenario. For example, the limiting flange 4 may not be provided with an annular convex edge 41. For another example, the limiting flange 4 can also be fixedly connected to the end face of the limiting sleeve 2, such as the inner end face of the limiting sleeve 2 is provided with a third connecting hole, the limiting flange 4 is provided with a fourth connecting hole, and the third connecting hole is connected to the fourth connecting hole by a fastener. Of course, when the first connecting hole 22 as described above is provided on the inner end face of the limiting sleeve 2, the limiting flange 4 can also be provided on the outer end face of the limiting sleeve 2, and the third connecting hole is provided on the outer end face of the limiting sleeve 2. Alternatively, the limiting flange 4 can also be connected to the mounting hole 11 by a transition fit or a clearance fit. For another example, the flange hole on the limiting flange 4 can also be configured to simultaneously match the limiting holes 21 on multiple models of limiting sleeves 2, so that only one limiting flange 4 is required to achieve the positioning of the bearing box 32 at different installation positions.

[0067] For another example, although the above embodiment is described in conjunction with the example of setting three types of limit sleeves 2, those skilled in the art can adjust the number of types of limit sleeves 2 based on specific application scenarios. For example, the limit sleeves 2 can also include two, four or more types. Moreover, some types can be reused, for example Figure 3A and Figure 3C If the positions of the limiting holes 21 are symmetrically arranged, only one of the two can be retained. In addition, the aperture of the limiting holes 21 provided on each model of the limiting sleeve 2 can also be adjusted, so that the limiting sleeve 2 can be applied to more application scenarios.

[0068] For another example, although the above-mentioned embodiment is introduced in conjunction with three mounting holes 11 set on each side wall of the cutting frame 1, this is only a preferred embodiment. In other embodiments, the number of mounting holes 11 on the cutting frame 1 can be selected based on actual needs, such as one or two mounting holes 11 can be opened, or when the number of main roller assemblies 3 is larger, more mounting holes 11 can be opened.

[0069] The following is an introduction to the process of adjusting the wheelbase of the main roller 31 in the first embodiment. When the wheelbase of the main roller 31 needs to be adjusted, first remove the fasteners on the two bearing boxes 32 corresponding to the main roller 31 whose wheelbase needs to be adjusted, and pull the bearing box 32 out of the limiting sleeve 2. At this time, the main roller 31 can be removed. Then further pull the bearing box 32 out of the limiting sleeve 2 so that the bearing box 32 is removed. Then remove and replace the limiting sleeve 2 of another model, and push the bearing box 32 back into the limiting sleeve 2. Finally, install the main roller 31 between the two bearing boxes 32, and replace the limiting flange 4 that is suitable for the current position of the bearing box 32 to limit the bearing box 32, and then fix the bearing box 32 on the limiting sleeve 2. At this point, the adjustment of the wheelbase of the main roller 31 is completed.

[0070] Combine the following Figures 4 to 7 , the second preferred implementation of the present application is introduced.

[0071] like Figure 4 As shown, the second preferred embodiment of the present application is different from the first embodiment in that a plurality of limiting holes 21 are provided on the limiting sleeve 2, and two adjacent limiting holes 21 among the plurality of limiting holes 21 partially overlap. Three mounting holes 11 are provided on each side wall of the cutting frame 1, two mounting holes 11 are provided at the top, and one mounting hole 11 is provided at the bottom and located between the two mounting holes 11, and a limiting sleeve 2 can be installed in each mounting hole 11. Among them, the plurality of limiting holes 21 of the two limiting sleeves 2 located at the top are arranged in the horizontal direction, and the plurality of limiting holes 21 of the limiting sleeve 2 located at the bottom are arranged in the vertical direction, so that the position adjustment of the upper main roller assembly 3 in the horizontal direction and the position adjustment of the lower main roller assembly 3 in the vertical direction can be realized.

[0072] See Figure 6 And follow Figure 6 In the position shown, the limiting sleeve 2 is provided with three limiting holes 21a, 21b, 21c, and the diameters of the three limiting holes 21a, 21b, 21c are equal (the cut-off parts of the three limiting holes 21a, 21b, 21c are in Figure 6(indicated by dotted lines in the figure), each limiting hole can be used for the installation of the bearing box 32. Among the three limiting holes 21a, 21b, and 21c, the limiting hole 21a on the left side partially overlaps with the limiting hole 21b in the middle, the limiting hole 21b in the middle partially overlaps with the limiting hole 21c on the right side, and the limiting hole 21a on the left side and the limiting hole 21c on the right side also have a small overlap. After opening, a limiting protrusion 26 is formed between two adjacent limiting holes, and the limiting protrusion 26 has an arc-shaped transition surface that matches the two limiting holes forming the limiting protrusion 26. When the bearing box 32 is installed in the limiting hole 21, the outer diameter of the bearing box 32 fits the arc-shaped transition surface.

[0073] See also Figure 6 and Figure 7 A first step groove 23 is formed around the limiting hole 21 on the end surface of the limiting sleeve 2 on which the first connecting hole 22 is provided. In the present application, a first step groove 23 is formed around the limiting hole 21 on the outer end surface of the limiting sleeve 2 (the side away from the inside of the cutting frame 1), and the first connecting hole 22 is opened at the bottom of the first step groove 23. A second step groove 25 is formed around the limiting hole 21 on the inner end surface of the limiting sleeve 2 (the side close to the inside of the cutting frame 1), and a third connecting hole is opened on the inner end surface of the limiting sleeve 2.

[0074] Reference Figure 5 In the installed state, the flange edge 321 of the bearing box 32 abuts against the first step groove 23, and the fastener passes through the second connection hole 322 of the flange edge 321 and is fastened in the first connection hole 22. The limiting flange 4 is located on the inner end surface of the limiting sleeve 2, and a fourth connection hole is opened on the limiting flange 4. The fastener passes through the fourth connection hole and is fastened in the third connection hole on the inner end surface of the limiting sleeve 2, and the annular convex edge 41 is sleeved on the bearing box 32 and inserted into the second step groove 25.

[0075] The above arrangement can save materials and realize multi-position adjustment of the main roller 31 through one limiting sleeve 2. A limiting protrusion 26 is formed between two adjacent limiting holes 21, which is conducive to improving the installation and positioning accuracy of the bearing box 32.

[0076] Of course, the above-mentioned arrangement is only preferred, and those skilled in the art can adjust the above-mentioned arrangement without departing from the principle of the present application. For example, although the above-mentioned embodiment is described in conjunction with the three limiting holes 21a, 21b, and 21c provided on the limiting sleeve 2, this is not restrictive, and the number of limiting holes 21 can also be two, four, or more. At the same time, the partial overlap between two adjacent limiting holes 21 is only a preferred embodiment, and those skilled in the art can also set the limiting holes 21 separately, that is, set a plurality of limiting holes 21 that do not overlap with each other on the limiting sleeve 2.

[0077] For another example, the first step groove 23 and the second step groove 25 are not necessarily provided, and those skilled in the art can choose whether to provide them and the number of them based on the specific application scenario, and these changes do not deviate from the principles of the present application. Of course, one or both of the first step groove 23 and the second step groove 25 can also be applied to the first embodiment.

[0078] For another example, the structure of forming the limiting protrusion 26 between the two limiting holes 21 is only preferred, and those skilled in the art can choose whether to set the structure and the specific form of the structure based on the specific application scenario. For example, the limiting protrusion 26 can also only form a partially arc-shaped transition surface that matches the limiting hole 21. For another example, the limiting protrusion 26 can also be omitted. Of course, if this structure is omitted, it will be disadvantageous to position the bearing box 32.

[0079] For another example, although the above embodiment is described in conjunction with the equal diameters of the plurality of limiting holes 21 , the diameter size relationship between the limiting holes 21 is not fixed, and those skilled in the art can select the diameter of each limiting hole 21 based on the specific application scenario.

[0080] The following is an introduction to the process of adjusting the wheelbase of the main roller 31 in the second embodiment. When the wheelbase of the main roller 31 needs to be adjusted, first remove the fasteners connecting the two bearing boxes 32 corresponding to the main roller 31 whose wheelbase needs to be adjusted and the limit sleeve 2, and pull the bearing box 32 out of the limit sleeve 2, and then the main roller 31 can be removed. Then further pull out the bearing box 32 from the limit sleeve 2 so that the bearing box 32 is removed. Then install the bearing box 32 into the other limit hole 21 of the limit sleeve 2, and push the bearing box 32 back into the limit sleeve 2, and finally install the main roller 31 between the two bearing boxes 32, and replace the limit flange 4 that is suitable for the current position of the bearing box 32 to limit the bearing box 32, and then fix the bearing box 32 on the limit sleeve 2, so that the adjustment of the wheelbase of the main roller 31 is completed.

[0081] The present application also provides a wire cutting machine, which includes the cutting assembly of the above embodiment. Preferably, the wire cutting machine of the present application is a slicer. Of course, the wire cutting machine can also be a mortar machine, etc.

[0082] The wire cutting machine of the present application can simplify the adjustment process of the wheelbase of the main roller 31 by adopting the above-mentioned cutting assembly, reduce the wheelbase adjustment time, and improve production efficiency.
