[0035] As mentioned in the background technology section above, when customers use multi-layer cutting tables, the types of fabrics used are increasing, the precision requirements for cutting pieces are getting higher and higher, and the requirements for the sharpness of the cutting knife are also constantly increasing. The flatness of the tool after grinding will have a great impact on the cutting quality, cutting efficiency, and the cost of using the cutting table. The existing multi-layer cutting table uses a double sand column grinding method, and the double column structure is a cantilever beam. The grinding effect is severely attenuated during long-term application, the stability of the grinding knife is poor, and the sand column is inconvenient to repair and maintain, etc., resulting in the tool not being sharp after grinding, the sharpness cannot be maintained, and the cost of use is high.
[0036] To this end, the present application provides a knife sharpening device for a cutting table, which improves stability and durability, reduces maintenance costs, and improves cutting efficiency and quality through the optimized design of a simply supported beam structure.
[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0038] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0039] Please refer to Figure 1 , Figure 1 A structural diagram of a knife sharpening device for a cutting table provided in an embodiment of the present application.
[0040] In a first specific embodiment, Figure 1 As shown, the knife sharpening device for a cutting table provided in the embodiment of the present application mainly includes a fixing plate 1, a mounting base plate 2, a supporting plate 3 and a knife sharpening mechanism 4.
[0041] The fixing plate 1 is arranged along the first direction, the mounting base plate 2 is arranged along the first direction, and the mounting base plate 2 and the fixing plate 1 are spaced apart in the second direction, the support plate 3 is arranged between the fixing plate 1 and the mounting base plate 2, the sharpening mechanism 4 is arranged between the fixing plate 1 and the mounting base plate 2, the sharpening mechanism 4 is rotatable, and the rotation axis of the sharpening mechanism 4 is arranged along the second direction.
[0042] The first direction is perpendicular to the second direction. Optionally, the first direction is a horizontal direction and the second direction is a vertical direction.
[0043] The knife sharpening device for a cutting table provided in the present application is innovative in that the support method of the knife sharpening mechanism 4 is fundamentally changed, and the original cantilever beam structure is transformed into a simply supported beam structure by adding a support plate 3. Specifically, the fixed plate 1 is arranged along a first direction, and is spaced apart in a second direction from the mounting base plate 2 which is also arranged along the first direction, and these two directions are perpendicular. The support plate 3 is arranged between the fixed plate 1 and the mounting base plate 2, and through the combination of the support plate 3 and the mounting base plate 2, an additional support point is provided for the knife sharpening mechanism 4. The knife sharpening mechanism 4 itself is arranged between the fixed plate 1 and the mounting base plate 2, and can rotate, and its rotation axis is arranged along the second direction. Such a layout allows the knife sharpening mechanism 4 to perform efficient knife sharpening actions during the cutting process.
[0044] This structural improvement brings about significant beneficial effects. First, the sharpening mechanism 4 in the form of a simply supported beam significantly improves the overall stability and durability due to the arrangement of the support plate 3 and the mounting base plate 2. Secondly, the rotating design of the sharpening mechanism 4 makes the sharpening process more flexible, which helps to reduce the attenuation of the grinding effect in long-cycle applications. In addition, the arrangement of the support plate 3 simplifies the repair and maintenance of the sharpening mechanism 4, because the stability of the sharpening mechanism 4 is enhanced, the frequency of repairs is reduced, and the simplified structure also makes the repair work easier to perform. Ultimately, these improvements work together to significantly improve cutting efficiency and cut piece quality, while reducing maintenance costs, bringing higher economic benefits and process performance to the cutting table operation.
[0045] In combination with the above structure and process description, it can be seen that the knife sharpening device for a cutting table has at least the following beneficial effects: the knife sharpening device for a cutting table changes the support method of the knife sharpening mechanism 4 and adds a support plate 3, thereby transforming the cantilever beam form into a simply supported beam form, thereby effectively improving the stability and durability of the knife sharpening mechanism 4, reducing the attenuation of the grinding effect in long-cycle applications, simplifying the repair and maintenance of the sand column, thereby significantly improving the cutting efficiency and the quality of the cut pieces, and reducing the maintenance cost.
[0046] Please continue to refer to Figure 1 And refer to Figure 2 , Figure 2 for Figure 1 AA section view of a knife sharpening device for a cutting table.
[0047] In some embodiments, the sharpening mechanism 4 includes a sharpening shaft 41 and a sharpening structure 42 .
[0048] The first end of the sharpening shaft 41 is installed on the fixed plate 1, the second end of the sharpening shaft 41 is installed on the mounting base plate 2, and the central axis of the sharpening shaft 41 is set along the second direction; the sharpening structure 42 is sleeved on the sharpening shaft 41, and the sharpening structure 42 can rotate around the sharpening shaft 41, and the rotation axis of the sharpening structure 42 coincides with the central axis of the sharpening shaft 41.
[0049] In this embodiment, the knife sharpening mechanism 4 is the core part of the knife sharpening device for the cutting machine. The knife sharpening shaft 41 is the central component of the knife sharpening mechanism 4, one end of which is fixedly mounted on the fixed plate 1, and the other end is mounted on the mounting base plate 2. The central axis of the knife sharpening shaft 41 is arranged along the second direction, which means that the knife sharpening shaft 41 is perpendicular to the planes of the fixed plate 1 and the mounting base plate 2.
[0050] The sharpening structure 42 is a component mounted on the sharpening shaft 41, and is designed to rotate around the sharpening shaft 41. The rotation axis of the sharpening structure 42 coincides with the central axis of the sharpening shaft 41, and such a design allows the sharpening structure 42 to rotate freely on the sharpening shaft 41. The rotation ability of the sharpening structure 42 is the key to achieving precise sharpening, because it can ensure that the cutter can be properly sharpened at any required angle.
[0051] Due to the assembly relationship between the sharpening shaft 41 and the sharpening structure 42 , the sharpening structure 42 on the sharpening shaft 41 can be disassembled and replaced when the sharpening structure 42 is worn out.
[0052] As an option, the sharpening mechanism 4 uses a sharpening sand column.
[0053] In some embodiments, the knife sharpening mechanism 4 further includes a bearing assembly 43 .
[0054] The bearing assembly 43 is disposed between the sharpening shaft 41 and the sharpening structure 42 . The inner ring of the bearing assembly 43 is connected to the sharpening shaft 41 , and the outer ring of the bearing assembly 43 is connected to the sharpening structure 42 .
[0055] In this embodiment, the bearing assembly 43 is disposed between the sharpening shaft 41 and the sharpening structure 42, and plays a role of connection and support. The bearing assembly 43 is composed of two inner and outer rings, the inner ring is connected to the sharpening shaft 41, and the outer ring is connected to the sharpening structure 42. Such a configuration enables the sharpening structure 42 to rotate smoothly on the sharpening shaft 41. The design of the bearing assembly 43 allows the sharpening structure 42 to achieve low-friction rotation when performing the sharpening action, thereby ensuring a smooth and precise sharpening process.
[0056] The use of the bearing assembly 43 also helps to improve the overall stability and durability of the sharpening mechanism 4. It can not only withstand the force generated during sharpening, but also maintain the precise fit between the sharpening structure 42 and the sharpening shaft 41, reduce the wear caused by the sharpening action, and extend the service life of the sharpening mechanism 4.
[0057] In some embodiments, the bearing assembly 43 includes two groups, the first group of bearing assemblies 43 is arranged at one end of the sharpening mechanism 4 close to the fixing plate 1 , and the second group of bearing assemblies 43 is arranged at one end of the sharpening mechanism 4 close to the mounting base plate 2 .
[0058] In this embodiment, the design of the knife sharpening mechanism 4 is further refined, including the configuration of two sets of bearing assemblies 43. The function of the bearing assembly 43 is to provide connection and support between the knife sharpening shaft 41 and the knife sharpening structure 42, so as to ensure the stable operation of the knife sharpening mechanism 4. Specifically, the first set of bearing assemblies 43 is arranged at one end of the knife sharpening mechanism 4 close to the fixed plate, and the second set of bearing assemblies 43 is located at the other end of the knife sharpening mechanism 4 close to the mounting base plate.
[0059] This design concept of supporting at both ends corresponds to the structural characteristics of a simply supported beam, which is fixed at both ends and can provide good load-bearing capacity and stability. In the sharpening mechanism 4, the provision of two sets of bearing assemblies 43 not only ensures the stable support of the sharpening shaft 41, but also allows the sharpening structure 42 to rotate flexibly on the sharpening shaft 41 without being offset or vibrated due to the sharpening force. In addition, the support at both ends can also provide uniform load distribution, reduce local stress concentration, and thus extend the service life of the sharpening mechanism 4. At the same time, this design also helps to simplify the maintenance of the sharpening mechanism 4, because the bearing assemblies 43 at both ends can be independently inspected and replaced, ensuring that the sharpening mechanism 4 always maintains the best working condition.
[0060] In some embodiments, the knife sharpening mechanism 4 further includes a knife sharpening fixing shaft 44 .
[0061] The knife sharpening fixing shaft 44 is installed on the installation base plate 2 , and the knife sharpening fixing shaft 44 is used to fix the knife sharpening shaft 41 to the installation base plate 2 .
[0062] In this embodiment, the main function of the knife sharpening fixed shaft 44 is to firmly fix the knife sharpening shaft 41 to the mounting base plate 2. Specifically, the existence of the knife sharpening fixed shaft 44 ensures the precise position and stability of the knife sharpening shaft 41 during the knife sharpening process. The knife sharpening shaft 41 is the center of rotation of the knife sharpening structure 42, and its stability is crucial to the performance of the entire knife sharpening mechanism 4. The knife sharpening fixed shaft 44 provides a solid support point for the knife sharpening shaft 41 through a fixed connection with the mounting base plate 2, thereby reducing vibration and deviation that may occur during knife sharpening.
[0063] In addition, the knife sharpening fixed shaft 44 also helps to improve the installation efficiency and maintenance convenience of the knife sharpening mechanism 4. When the knife sharpening mechanism 4 needs to be maintained or the knife sharpening structure 42 needs to be replaced, the knife sharpening fixed shaft 44 can be used as a reliable fixing point to simplify the assembly and disassembly process.
[0064] Optionally, a through hole is opened on the knife sharpening fixed shaft 44, and a countersunk hole is opened on the knife sharpening shaft 41. The knife sharpening fixed shaft 44 is pressed against the mounting base plate 2 by means of fasteners passing through the knife sharpening fixed shaft 44 and connected to the knife sharpening shaft 41. At the same time, the knife sharpening fixed shaft 44 fixes the knife sharpening shaft 41. When replacing, only the fasteners need to be removed to remove the knife sharpening fixed shaft 44 and the mounting base plate 2 to replace the knife sharpening structure 42.
[0065] In some embodiments, the knife sharpening fixed shaft 44 is coaxially disposed with the knife sharpening shaft 41 , and the knife sharpening structure 42 is simultaneously mounted on the knife sharpening shaft 41 and the knife sharpening fixed shaft 44 .
[0066] Two bearing assemblies 43 are provided at one end of the sharpening mechanism 4 close to the mounting base plate 2 , the first bearing assembly 43 is provided between the sharpening shaft 41 and the sharpening structure 42 , and the second bearing assembly 43 is provided between the sharpening fixed shaft 44 and the sharpening structure 42 .
[0067] In these embodiments, the knife sharpening structure 42 is designed to be mounted on the knife sharpening shaft 41 and the knife sharpening fixed shaft 44. The knife sharpening fixed shaft 44 is equivalent to extending the knife sharpening shaft 41, thereby improving the support effect of the knife sharpening structure 42. In addition, the knife sharpening shaft 41 and the knife sharpening fixed shaft 44 are both configured with corresponding bearing assemblies 43. Such a configuration provides a double-position support for the knife sharpening structure 42, ensuring the stability and accuracy of the knife sharpening structure 42 when rotating on the knife sharpening shaft 41.
[0068] In some embodiments, the fixing plate 1 is provided with a first positioning hole 11 , the first end of the sharpening shaft 41 is provided with a shaft portion 411 and a shoulder portion 412 , the shaft portion 411 is installed in the first positioning hole 11 , and the shoulder portion 412 is in contact with the back surface of the fixing plate 1 .
[0069] In this embodiment, when the sharpening shaft 41 is installed on the fixed plate 1, the verticality of the sharpening shaft 41 and the fixed plate 1 is ensured by the matching relationship between the shaft portion 411 and the shoulder portion 412 and the first positioning hole 11 and the back surface of the fixed plate 1.
[0070] In some cases, when there are two sharpening mechanisms 4 , the matching relationship between the sharpening shaft 41 and the fixing plate 1 also ensures the parallelism of the two sharpening shafts 41 of the two sharpening mechanisms 4 .
[0071] In some embodiments, the mounting base plate 2 and the support plate 3 are provided with matching second positioning holes, the number of the second positioning holes is multiple, and the center line connecting at least two of the second positioning holes does not coincide with or is not parallel to the second direction.
[0072] In this embodiment, when the support plate 3 is mounted on the mounting base plate 2, the second positioning holes between the mounting base plate 2 and the support plate 3 are matched to facilitate positioning during installation. In addition, the design of multiple second positioning holes can also provide a foolproof effect and optimize load distribution.
[0073] In some embodiments, the support plate 3 includes a vertical portion 31 and horizontal portions 32 arranged at both ends of the vertical portion 31 , the horizontal portion 32 at the first end of the vertical portion 31 is connected to the fixing plate 1 , and the horizontal portion 32 at the second end of the vertical portion 31 is connected to the mounting base plate 2 .
[0074] In this embodiment, by combining the vertical portion 31 and the horizontal portions 32 at both ends, a stable corner support structure is formed at both ends, which helps to improve the overall stability of the knife sharpening mechanism 4. The vertical support of the vertical portion 31 reduces the vibration during sharpening, and the connection of the horizontal portions 32 at both ends ensures the horizontal positioning accuracy of the knife sharpening mechanism 4.
[0075] In some embodiments, there are two sharpening mechanisms 4 , which are arranged side by side between the fixing plate 1 and the mounting base plate 2 , and the distances between the two sharpening mechanisms 4 and the supporting plate 3 are equal.
[0076] Please continue to refer to Figure 1 and Figure 2 In a specific embodiment, a knife sharpening device for a cutting table is described as follows.
[0077] Two sharpening mechanisms 4 are installed on the fixed plate 1. When the sharpening mechanisms 4 and the fixed plate 1 are installed for the first time, it is necessary to ensure the verticality of the two and the parallelism of the two sharpening mechanisms 4. The sharpening structure 42 is installed on the sharpening shaft 41 through the sharpening fixed shaft 44 and the mounting base plate 2, so that the sharpness and straightness of the blade sharpened by the sharpening mechanism 4 during operation can be ensured. Among them, there is a support plate 3 between the mounting base plate 2 and the fixed plate 1, which is fixedly connected by screws to form a simply supported beam, which increases the overall stability and rigidity of the sharpening mechanism 4 during long-term operation. Since the sharpening structure 42 is a consumable and needs to be disassembled and replaced, when replacing, it is only necessary to disassemble the sharpening fixed shaft 44 and the screws on the mounting base plate 2 to easily disassemble the sharpening structure 42.
[0078] The advantages of the knife sharpening device for cutting machines are as follows. First, the knife sharpening mechanism 4 exhibits good stability during operation, which is due to the rigidity of its structural design, ensuring the accuracy and reliability during the knife sharpening process. Second, the knife sharpening structure 42 is designed to be very convenient to disassemble when it is needed as a consumable. This easy-to-maintain feature not only improves the operating efficiency of the knife sharpening device, but also reduces the maintenance cost in long-term operation.
[0079] It should be noted that many of the components mentioned in this application are universal standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or through conventional experimental methods.
[0080] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
[0081] The above is a detailed introduction to the knife sharpening device for cutting tables provided by the present application.
