[0044] Referring to Figures 1-4 For the first embodiment of the present application, an automatic knife sharpener knife ring structure is proposed, which comprises a device main body 1; an annular mounting frame 2 is rotationally arranged in the device main body 1; a plurality of cutter mounting frames 3 are arranged on the annular mounting frame 2 along the axis of the annular mounting frame 2 in a circumferentially uniform manner, the cutter mounting frame 3 has a tool setting hole 301, and the cutter mounting frame 3 is provided with a blade 4 near one end of the axis of the annular mounting frame 2; a positioning device 5 is arranged on the device main body 1 and located inside the annular mounting frame 2; a first mounting frame 6 is arranged on the device main body 1 and located outside the annular mounting frame 2; a first telescopic member 7 is arranged on the first mounting frame 6, and the first telescopic member 7 has a tool setting rod 8 at the extending end thereof, after the first telescopic member 7 is extended, the tool setting rod 8 is inserted into the tool setting hole 301 and abuts against one end of the blade 4, thereby pushing the other end of the blade 4 to abut against the positioning device 5.

[0045] In this embodiment, in order to solve the problem of low tool setting efficiency and low precision of the automatic knife sharpener knife ring in the related art, an automatic knife sharpener knife ring structure is designed. Inside the device main body 1 of the automatic knife sharpener, a sturdy annular mounting frame 2 is installed, which can smoothly rotate in the device main body 1. A plurality of cutter mounting frames 3 are fixed on the annular mounting frame 2 in a circumferentially uniform manner along the axis of the annular mounting frame 2. Each cutter mounting frame 3 is provided with a tool setting hole 301, and the position thereof is accurately measured and designed. A blade 4 is installed at one end of the cutter mounting frame 3 near the axis of the annular mounting frame 2. On the device main body 1, a positioning device 5 is installed inside the annular mounting frame 2, which can be an adjustable positioning block and can be adjusted according to the size of different blades 4. A first mounting frame 6 is fixed on the device main body 1 outside the annular mounting frame 2, and an electric hydraulic telescopic member is installed on the first mounting frame 6 as a first telescopic member 7. The extending end of the first telescopic member 7 is connected to an elongated tool setting rod 8, which can be accurately inserted into the tool setting hole 301 of the cutter mounting frame 3 when the first telescopic member 7 is extended, and tightly abuts against one end of the blade 4, thereby pushing the other end of the blade 4 to contact the positioning device 5.

[0046] The advantage is that the blade 4 can be quickly and accurately positioned, and the working efficiency and grinding precision of the knife sharpener are improved. The design of the annular mounting frame 2 makes the switching of the blade 4 more convenient, reducing the operation time.

[0056] Further, the pressing plate 303 is provided on the mounting seat 302 by bolts.

[0057] In this embodiment, the pressing plate 303 is evenly distributed around the mounting seat 302 by four bolts, firmly clamping the blade 4 between the mounting seat 302 and the pressing plate 303. When installing and replacing the blade 4, only the bolts need to be loosened, and the pressing plate 303 can be easily removed for replacement of the blade 4. The material and size of the bolts are carefully selected to ensure sufficient strength and durability.

[0058] The advantage is that the bolt connection method is simple and reliable, and easy to operate. The tightening degree of the bolts can be adjusted according to the thickness of different blades 4 to ensure that the blade 4 is installed firmly and stably.

[0060] In this embodiment, a second mounting frame 11 is fixed on the device main body 1 outside the annular mounting frame 2, and the second mounting frame 11 is slidingly provided on the device main body 1 through a slider and guide rail structure. A rotating wrench 12 is installed on the second mounting frame 11. When the tool setting rod 8 is in abutment with the blade 4, the second mounting frame 11 slides on the device main body 1, so that the rotating end of the rotating wrench 12 can be buckled with the bolt on the pressing plate 303.

[0061] The advantage is that the quick tightening and loosening operation of the bolt on the pressing plate 303 is realized, without using the traditional wrench tool, improving the efficiency of the blade 4 installation and replacement. The sliding design of the turning wrench 12 enables it to be quickly and accurately buckled with the bolt when needed, reducing operation time and labor intensity.

[0062] Further, the second mounting frame 11 is swingably arranged on the device body 1, and further comprises a third telescopic member 13, one end of which is hingedly arranged on the device body 1, and the other end of which is hingedly connected with one end of the second mounting frame 11.

[0063] In this embodiment, the second mounting frame 11 is hingedly mounted on the device body 1, so that it can swing. A pneumatic telescopic member is mounted on the device body 1 as the third telescopic member 13, one end of which is hingedly connected to the device body 1 through a hinge, and the other end is hingedly connected to one end of the second mounting frame 11 through another hinge. When the third telescopic member 13 is telescoped, the second mounting frame 11 will swing around the hinge on the device body 1. For example, when it is necessary to adjust the position of the turning wrench 12, the angle of the second mounting frame 11 can be changed by controlling the telescoping of the third telescopic member 13, so that the turning wrench 12 can be better buckled with the bolt on the pressing plate 303.

[0064] The advantage is that the angle of the second mounting frame 11 can be flexibly adjusted, so that the turning wrench 12 can better adapt to bolts in different positions, improving the convenience and efficiency of operation. At the same time, the design of the third telescopic member 13 also increases the operation range of the turning wrench 12, so that it can handle knife holders 3 of different sizes and shapes.

[0066] In this embodiment, an installation plate 14 is installed at the extending end of the first telescopic member 7, and the installation plate 14 is provided with an installation portion 1401, and the tool bar 8 is fixed on the installation portion 1401. A pressing rod 15 is also installed on the installation plate 14, and the pressing rod 15 is slidably arranged on the installation portion 1401 through a sleeve and guide rod structure. When the tool bar 8 abuts against the blade 4, the pressing rod 15 slides on the installation plate 14, so that the end of the pressing rod 15 away from the installation portion 1401 can abut against the side of the pressing plate 303 away from the installation base 302. For example, during the tool setting process, the pressing rod 15 can play a role of auxiliary fixing of the blade 4, so as to prevent the blade 4 from moving during the tool setting process.

[0067] The advantage is that the stability of the blade 4 during the tool setting process is improved, and the accuracy and reliability of the tool setting are improved. At the same time, the design of the installation plate 14 also makes the installation of the tool bar 8 and the pressing rod 15 more firm and stable.

[0068] Further, the pressing rod 15 has a first gear tooth 1501 on one side, and the abutting rod 16 has a second gear tooth 1601 on one side, and the abutting rod 16 is slidably arranged on the installation portion 1401. After the first telescopic member 7 is extended, the end of the abutting rod 16 abuts against the tool mounting rack 3, so that the abutting rod 16 slides on the installation portion 1401. The transmission wheel 17 is rotatably arranged on the installation portion 1401 and is engaged with the first gear tooth 1501 and the second gear tooth 1601. After the abutting rod 16 slides, the pressing rod 15 is driven to slide by the transmission wheel 17.

[0069] In this embodiment, the first gear tooth 1501 is machined on one side of the pressing rod 15, and the second gear tooth 1601 is machined on one side of the abutting rod 16. The abutting rod 16 is slidably arranged on the installation portion 1401 through a slider and guide rail structure. After the first telescopic member 7 is extended, the end of the abutting rod 16 abuts against the tool mounting rack 3, so that the abutting rod 16 slides on the installation portion 1401. A transmission wheel 17 is also installed on the installation portion 1401, and the transmission wheel 17 is connected to the installation portion 1401 through a rotating shaft, so that it can freely rotate. The transmission wheel 17 is engaged with the first gear tooth 1501 on the pressing rod 15 and the second gear tooth 1601 on the abutting rod 16, respectively. When the abutting rod 16 slides, the pressing rod 15 is driven to slide on the installation plate 14 by the transmission of the transmission wheel 17. For example, after the tool bar 8 abuts against the blade 4, the abutting rod 16 abuts against the tool mounting rack 3 under the pushing of the first telescopic member 7, and then the pressing rod 15 is driven to slide by the transmission wheel 17, so that the end of the pressing rod 15 abuts against the pressing plate 303, preventing the blade 4 from being lifted and falling off during the tool setting process.

[0070] The advantage is that the automatic fixing and loosening operation of the blade 4 is realized, and the working efficiency and automation degree of the knife sharpener are improved. The design of the transmission wheel 17 makes the transmission between the abutting rod 16 and the pressing rod 15 more stable and reliable, reduces the error and unstable factors caused by manual operation. At the same time, this design also makes the whole knife ring structure more compact and efficient.

After the abutment rod (16) slides, the transmission wheel (17) drives the pressing rod (15) to slide.
