When it is necessary to grind and edge-open the ceramic knife, after clamping the ceramic knife through the clamping component 14, start the driving motor 2. The driving motor 2 drives the two first transmission gears 4 to rotate through the driving gear 3. At the same time, the first transmission gear 4 makes the second transmission gear 8 rotate through the transmission rod 5. The second transmission gear 8 makes the bevel gear 9 rotate through the meshing action with the bevel gear 9, and drives the grinding disc 12 to rotate through the electric telescopic column 10 and the telescopic connecting column 11, realizing double-sided synchronous grinding and edge-opening of multiple ceramic knives at the same time, and improving the processing efficiency.

[0036] As Figures 1 - 4 、 Figure 6 and Figure 8As shown, the clamping assembly 14 includes a module slide rail 1401, a mounting plate 1402, an adjusting gear 1403, a second connecting rod 1404, a lower fixing plate 1405, a first mounting groove 1406, a ceramic knife 1407, an upper fixing plate 1408, a second mounting groove 1409, a control gear 1411, a chain 1412, and a brake motor 1413;

[0037] The module slide rail 1401 is mounted on the mounting base 1. The mounting plate 1402 is slidably mounted on the module slide rail 1401. Four second connecting rods 1404 are rotatably mounted on the mounting plate 1402, and the second connecting rods 1404 penetrate through the mounting plate 1402.

Then, according to the processing requirements, the brake motor 1413 is started, so that the control gear 1411 drives the adjusting gears 1403 to rotate synchronously through the chain 1412. The adjusting gears 1403 drive the lower fixing plate 1405 to rotate through the second connecting rods 1404, and the processing angle of the ceramic knife clamped between the lower fixing plate 1405 and the upper fixing plate 1408 is adjusted. Knives with different cutting edge angle requirements can be processed, and the accuracy of the processing angle can also be improved. After that, the mounting plate 1402 moves the ceramic knife along the module slide rail 1401 to the processing position for grinding and sharpening.

[0038] As Figures 1 - 6 and Figures 9 - 10As shown, the progressive component 13 includes a reduction gear set 1301, a transmission connection column 1302, a pressing groove 1303, a mounting bracket 1304, a collar 1305, a rotating column 1306, a mounting hole 1307, an electric ejector rod 1308, an arc-shaped pressing plate 1309, a first chute 1310, a second chute 1311, a slider 1312, a first connecting rod 1313, a driving rod 1314, a mounting ring 1315, a first pull rod 1316, a second pull rod 1317, a spring 1318, a connecting block 1319, and a circular groove 1320;

[0039] The reduction gear set 1301 is mounted on the mounting base 1. The input gear of the reduction gear set 1301 meshes with the driving gear 3. A transmission connection column 1302 is mounted on the output gear of the reduction gear set 1301. A pressing groove 1303 is formed on the transmission connection column 1302. A mounting bracket 1304 is mounted on the mounting base 1. A collar 1305 is mounted on the mounting bracket 1304. A rotating column 1306 is rotatably mounted within the collar 1305. A mounting hole 1307 is formed on the rotating column 1306. The transmission connection column 1302 is inserted into the mounting hole 1307. Four electric ejector rods 1308 are mounted on the mounting hole 1307. Arc-shaped pressing plates 1309 are mounted on all four electric ejector rods 1308. A first chute 1310 is formed on the outer surface of the rotating column 1306. The first chute 1310 is spiral-shaped. A sensor is mounted on the first chute 1310. Two second chutes 1311 are symmetrically formed on the mounting base 1. Sliders 1312 are slidably mounted within the two second chutes 1311. A first connecting rod 1313 is mounted on the slider 1312. The two first connecting rods 1313 are connected by a mounting ring 1315. A driving rod 1314 is mounted on the mounting ring 1315. The lower end of the driving rod 1314 is slidably fitted within the first chute 1310. Circular grooves 1320 are formed at the centers of the opposite faces of the two grinding discs 12. Connecting blocks 1319 are rotatably mounted at the centers of the two circular grooves 1320. The driving rod 1314 is connected to one connecting block 1319 by a first pull rod 1316. The driving rod 1314 is connected to the other connecting block 1319 by a second pull rod 1317. The first pull rod 1316 and the second pull rod 1317 are connected by a plurality of springs 1318.

[0040] Through holes are formed at one ends of the first pull rod 1316 close to the driving rod 1314 and one ends of the second pull rod 1317 close to the driving rod 1314. The driving rod 1314 passes through the two through holes and is in rotational fit therewith. The end of the first pull rod 1316 away from the driving rod 1314 is hinged to one connecting block 1319. The end of the second pull rod 1317 away from the driving rod 1314 is hinged to the other connecting block 1319.

[0041] The electric push rod 1308 is electrically connected to both the inductor and the drive motor 2, and the electric telescopic column 10 is electrically connected to the drive motor 2.

[0042] A distance sensor 1410 is installed on the lower fixing plate 1405, and the distance sensor 1410 is electrically connected to both the drive motor 2 and the electric telescopic column 10.

[0043] When starting to grind and edge the ceramic knife, the drive motor 2 is started to send an electrical signal to control the electric push rod 1308 to extend, driving the arc-shaped pressing plate 1309 to hold the transmission connection column 1302 tightly through the pressing groove 1303, so that when the transmission connection column 1302 rotates, it drives the rotating column 1306 to rotate synchronously, facilitating the movement of the drive rod 1314 to the inductor, causing the inductor to control the electric push rod 1308 to contract. At the same time, when the distance sensor 1410 detects that the grinding disc 12 meets the requirements, it controls the drive motor 2 to stop operating.

[0044] When the drive motor 2 is started, the drive gear 3 drives the transmission connection column 1302 to rotate forward through the reduction gear set 1301, causing the drive rod 1314 to move horizontally along the first chute 1310 towards the side close to the drive motor 2. During the movement of the drive rod 1314, it can compress the spring 1318 through the first pull rod 1316 and the second pull rod 1317, and drive the two grinding discs 12 to move towards each other, realizing the progressive synchronous grinding of the two grinding discs 12 on the ceramic knife. When the inductor is triggered, the first pull rod 1316 and the second pull rod 1317 can drive the drive rod 1314 to move horizontally and reset under the elastic force of the spring 1318, thus realizing the reverse movement of the two grinding discs 12 and achieving the reset of the two grinding discs 12, facilitating subsequent use.

[0045] If the grinding disc 12 is worn, when the drive rod 1314 moves to the inductor, but the distance sensor 1410 detects that the grinding distance of the grinding disc 12 does not meet the requirements, the distance sensor 1410 can control the electric telescopic column 10 to extend, so that the electric telescopic column 10 drives the grinding disc 12 to continue to move through the telescopic connection column 11, and further realizes wear compensation to ensure the grinding requirements for the edge opening of the ceramic knife. When the distance sensor 1410 detects that it meets the requirements, it controls the electric telescopic column 10 to contract and reset.

[0046] As Figures 1 - 4 and Figures 6 - 7 shown, the mounting base 1 is further provided with a cleaning assembly 15, and by using the operation of the clamping assembly 14, the cleaning assembly 15 is driven to clean the grinding particles.

[0047] The cleaning component 15 includes an upper baffle 1501, side baffles 1502, a third connecting rod 1503, a cleaning plate 1504, guide rails 1505, an inclined plate 1506, a sewage outlet 1507, a fourth connecting rod 1508, an elastic plate 1509, a push rod 1510, and a collection bin 1511;

[0048] The upper baffle 1501 and side baffles 1502 are installed in the mounting seat 1. Two third chutes 1512 are symmetrically formed on the mounting plate 1402. The third connecting rods 1503 are slidably installed on the two third chutes 1512, and the two third connecting rods 1503 are connected by the cleaning plate 1504. Two guide rails 1505 are symmetrically installed in the mounting seat 1. The inclined plates 1506 are hingedly installed on the two guide rails 1505 on the side close to the mounting plate 1402. A sewage outlet 1507 is formed on the mounting seat 1. Two fourth connecting rods 1508 are symmetrically installed on the wall surface of the sewage outlet 1507. The elastic plate 1509 is installed on the fourth connecting rod 1508. The push rod 1510 is installed on the cleaning plate 1504 on the side close to the third connecting rod 1503. A collection bin 1511 is formed on the mounting seat 1, and the collection bin 1511 is communicated with the sewage outlet 1507. The splashing abrasive particles during the grinding process can be blocked by the provided upper baffle 1501 and side baffles 1502. The blocked abrasive particles will fall on the mounting seat 1. When the mounting plate 1402 moves along the module slide rail 1401 towards the grinding disc 12, the mounting plate 1402 can drive the cleaning plate 1504 to move synchronously through the third connecting rod 1503. When the cleaning plate 1504 touches the inclined plate 1506, the cleaning plate 1504 is squeezed and moves obliquely upward along the inclined plate 1506 onto the guide rail 1505, and drives the third connecting rod 1503 to move upward along the third chute 1512. The movement of the mounting plate 1402 drives the cleaning plate 1504 to continue moving along the guide rail 1505. When the cleaning plate 1504 moves to the end of the guide rail 1505, it will fall onto the mounting seat 1. After the grinding is completed, the mounting plate 1402 will drive the cleaning plate 1504 to reset synchronously during the reset process, so that the cleaning plate 1504 will push the abrasive particles falling on the mounting seat 1 into the sewage outlet 1507 during the reset process, facilitating the collection and treatment of the abrasive particles by the collection bin 1511. At the same time, when the push rod 1510 touches the elastic plate 1509 as the cleaning plate 1504 moves, the elastic plate 1509 is bent and deformed under the extrusion force of the push rod 1510. When the elastic plate 1509 is separated from the push rod 1510, the elastic plate 1509 can strike and collide with the cleaning plate 1504 under the elastic force, so that the abrasive particles adhered to the cleaning plate 1504 can be shaken off into the collection bin 1511 by the vibration force, facilitating the cleaning of the abrasive particles adhered to the cleaning plate 1504.

[0049] Working principle of the present invention:

[0050] When the ceramic knife needs to be ground and sharpened, after clamping the ceramic knife through the clamping assembly 14, start the drive motor 2. The drive motor 2 drives two first transmission gears 4 to rotate through the drive gear 3. At the same time, the first transmission gear 4 drives the second transmission gear 8 to rotate through the transmission rod 5. The second transmission gear 8 drives the bevel gear 9 to rotate through the meshing action with the bevel gear 9, and drives the grinding disc 12 to rotate through the electric telescopic column 10 and the telescopic connecting column 11, realizing double-sided synchronous grinding and edge sharpening of multiple ceramic knives at the same time, and improving the processing efficiency.

[0051] When the ceramic knife needs to be ground and sharpened, place the ceramic knife in the first installation groove 1406 of the lower fixing plate 1405, and then fix the upper fixing plate 1408 on the lower fixing plate 1405. The first installation groove 1406 and the second installation groove 1409 form a loop to fix the ceramic knife. Then, according to the processing requirements, start the brake motor 1413, so that the control gear 1411 drives the adjustment gear 1403 to rotate synchronously through the chain 1412. The adjustment gear 1403 drives the lower fixing plate 1405 to rotate through the second connecting rod 1404, and adjusts the processing angle of the ceramic knife clamped between the lower fixing plate 1405 and the upper fixing plate 1408. Tools with different cutting edge angle requirements can be processed, and the accuracy of the processing angle can also be improved. After that, the mounting plate 1402 moves the ceramic knife to the processing position along the module slide rail 1401 for grinding and edge sharpening.

[0052] When starting to grind and sharpen the ceramic knife, the drive motor 2 is started to send an electrical signal to control the electric ejector rod 1308 to extend, driving the arc-shaped pressing plate 1309 to hold the transmission connecting column 1302 tightly through the pressing groove 1303, so that when the transmission connecting column 1302 rotates, it drives the rotating column 1306 to rotate synchronously, which is convenient for moving the drive rod 1314 to the sensor, so that the sensor controls the electric ejector rod 1308 to contract. At the same time, when the distance sensor 1410 detects that the grinding disc 12 meets the requirements, it controls the drive motor 2 to stop operating.

[0053] When the drive motor 2 starts, the drive gear 3 drives the transmission connection column 1302 to rotate forward through the reduction gear set 1301, causing the drive rod 1314 to move laterally along the first chute 1310 towards the side close to the drive motor 2. During the movement of the drive rod 1314, it can compress the spring 1318 through the first pull rod 1316 and the second pull rod 1317, and drive the two grinding discs 12 to move towards each other, realizing the progressive synchronous grinding of the ceramic knife by the two grinding discs 12. When the sensor is triggered, the first pull rod 1316 and the second pull rod 1317 can drive the drive rod 1314 to move horizontally and reset under the elastic force of the spring 1318, thus realizing the reverse movement of the two grinding discs 12 and achieving the reset of the two grinding discs 12, which is convenient for subsequent use.

[0054] When the grinding disc 12 is worn, when the drive rod 1314 moves to the sensor, but the distance sensor 1410 detects that the grinding distance of the grinding disc 12 does not meet the requirements, the distance sensor 1410 can control the electric telescopic column 10 to extend, so that the electric telescopic column 10 drives the grinding disc 12 to continue to move through the telescopic connection column 11, and thus wear compensation can be realized to ensure the grinding requirements for the edge opening of the ceramic knife. When the distance sensor 1410 detects that the requirements are met, it controls the electric telescopic column 10 to contract and reset.

[0055] The splashing abrasive particles during the grinding process can be blocked by the provided upper baffle 1501 and side baffle 1502. The blocked abrasive particles will fall on the mounting base 1. When the mounting plate 1402 moves along the module slide rail 1401 towards the grinding disc 12, the mounting plate 1402 can drive the cleaning plate 1504 to move synchronously through the third connecting rod 1503. When the cleaning plate 1504 touches the inclined plate 1506, the cleaning plate 1504 is squeezed and moves obliquely upward along the inclined plate 1506 onto the guide rail 1505, and drives the third connecting rod 1503 to move upward along the third chute 1512. The movement of the mounting plate 1402 drives the cleaning plate 1504 to continue moving along the guide rail 1505. When the cleaning plate 1504 moves to the end of the guide rail 1505, it will fall onto the mounting base 1. After the grinding is completed, during the reset process of the mounting plate 1402, it will drive the cleaning plate 1504 to reset synchronously, so that the cleaning plate 1504 will push the abrasive particles falling on the mounting base 1 into the sewage outlet 1507 during the reset process, facilitating the collection bin 1511 to collect and process the abrasive particles. At the same time, when the push rod 1510 touches the elastic plate 1509 as the cleaning plate 1504 moves, the elastic plate 1509 bends and deforms under the extrusion force of the push rod 1510. When the elastic plate 1509 disengages from the push rod 1510, the elastic plate 1509 can strike and collide with the cleaning plate 1504 under the elastic force, so that the abrasive particles adhered to the cleaning plate 1504 can be shaken off into the collection bin 1511 by the vibration force, facilitating the cleaning of the abrasive particles adhered to the cleaning plate 1504.
