In the description of this utility model, "plurality" means two or more, and "several" means one or more, unless otherwise specifically defined.

[0032] The annular saw blade, saw blade driving mechanism and saw machine provided by the utility model are now described.

[0033] like Figure 1 and Figure 2 As shown, the first embodiment of the present invention provides an annular saw blade, comprising an annular base 10. The annular base 10 is an annular structure, and a cutter head 11 is provided on the outer edge, and inner teeth 12 for cooperating with a driving gear are provided on the inner edge.

[0034] Compared with the prior art, the annular saw blade provided in this embodiment has additional internal teeth 12 inside the annular base 10 of the annular saw blade. When in use, the annular saw blade can be driven by replacing the friction drive wheel of the saw machine with a gear, which is beneficial to reducing power loss and can make the drive of the annular saw blade more powerful, thereby reducing the occurrence of jamming.

[0035] like Figure 1 and Figure 2 As shown, the present invention provides a specific implementation method based on the first implementation method as follows.

[0036] A first limiting groove 13 is provided in the middle of the annular base 10 so as to cooperate with a limiting wheel on the saw machine to prevent the annular saw blade from deflecting.

[0037] The cutter head 11 is a diamond cutter head to improve wear resistance. At the same time, since the debris particles generated by the diamond cutter head when cutting stone are relatively large and the vibration on the saw blade is relatively large, it helps to remove the debris adhering to the inner teeth 12, reducing the possibility of debris being brought into the saw machine.

[0038] There are multiple cutter heads 11, which are arranged around the outer edge of the annular base 10, and adjacent cutter heads 11 are separated by arc grooves. Chamfers are provided on both sides of the edges of the cutter heads 11 to improve cutting performance.

[0039] like Figure 3 and Figure 4 As shown, based on the same inventive concept, the second embodiment of the present invention provides a saw blade driving mechanism, including the above-mentioned annular saw blade and a driving wheel assembly 20 , wherein the driving wheel assembly 20 is provided with external teeth that cooperate with the annular base 10 .

[0040] Compared with the prior art, the saw blade drive mechanism provided in this embodiment is beneficial to reducing power loss by providing the above-mentioned annular saw blade and drive wheel assembly 20, and can make the drive of the annular saw blade more powerful, thereby reducing the occurrence of jamming.

[0041] like Figures 3 to 6 As shown, the present invention provides a specific implementation method based on the first implementation method as follows.

[0042] A second limiting groove is provided on the outer edge of the driving wheel assembly 20, and the outer teeth are provided in the second limiting groove to position the annular saw blade and prevent the inner teeth 12 of the annular saw blade from separating from the outer teeth.

[0043] like Figure 5 and Figure 6 As shown, in some specific embodiments, the driving wheel assembly 20 includes a first limiting plate 21, a gear plate 23 and a second limiting plate 24. A positioning sleeve 22 is provided in the middle of the first limiting plate 21, and the positioning sleeve 22 protrudes from the side of the first limiting plate 21; the gear plate 23 is sleeved on the positioning sleeve 22, and the outer edge is provided with external teeth; the second limiting plate 24 is sleeved on the positioning sleeve 22; wherein, the outer diameters of the first limiting plate 21 and the second limiting plate 24 are both larger than the outer diameter of the gear plate 23, and the gear plate 23 is located between the first limiting plate 21 and the second limiting plate 24 to form a second limiting groove.

[0044] During installation, the positioning sleeve 22 is placed on the saw machine's drive shaft, and then the annular saw blade is installed. The gear plate 23 and the second limiting plate 24 are then placed on the positioning sleeve 22 in sequence, so that the gear plate 23 engages with the annular saw blade, and the annular saw blade is positioned using the second limiting plate 24. This arrangement facilitates the installation and positioning of the annular saw blade while improving the tightness of the connection. It also facilitates manufacturing, replacement, and maintenance.

[0045] The height of the positioning sleeve 22 is less than or equal to the sum of the thicknesses of the gear plate 23 and the second limiting plate 24, so that the entire driving wheel assembly 20 can be fixed to the driving shaft of the saw machine by fastening bolts, and the first limiting plate 21, the gear plate 23 and the second limiting plate 24 can be tightened to avoid relative rotation.

[0046] Positioning structures are provided between the gear plate 23 and the positioning sleeve 22 and between the second limiting plate 24 and the positioning sleeve 22 to prevent relative rotation between the first limiting plate 21, the gear plate 23 and the second limiting plate 24; specifically, the positioning structure is a keyway structure or a card slot structure, etc., which can be used for positioning and fixing.

[0047] Based on the same inventive concept, a third embodiment of the present utility model provides a sawing machine, comprising the above-mentioned annular saw blade or the above-mentioned saw blade driving mechanism.

[0048] Compared with the prior art, the saw machine provided in this embodiment is conducive to reducing power loss by providing the above-mentioned annular saw blade or the above-mentioned saw blade driving mechanism, and can make the driving of the annular saw blade more powerful, thereby reducing the occurrence of jamming.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
