[0037] The cleaning block 204 is provided with a through hole in communication with the sleeve 203, and the suction pump 207 generates suction in the air suction pipe 206, so that the impurities inside the cleaning block 204 will move to the inside of the sleeve 203 under the action of the suction, and then enter the connecting sleeve 205 through the discharge hole 203-1, and then be sucked away by the air suction pipe 206 and transported to a designated position, so as to avoid the impurities inside the cleaning block 204 from adhering to the blade again.

[0038] The air suction pipe 206 has two sections installed at the air suction port and the air outlet of the suction pump 207.

[0043] Embodiment 2

[0044] Reference Figures 1-9 This is the second embodiment of the application, which is based on the previous embodiment.

[0045] Specifically, the grinding assembly 300 further comprises a blocking piece 308, the blocking piece 308 comprises a fixed frame 308a fixed at the center of the connecting pipe 307 and in communication with the connecting pipe 307, a baffle 308b is arranged in the fixed frame 308a, and a motor 308c is fixed at the top of the fixed frame 308a, and the output shaft of the motor 308c is fixed with the baffle 308b.

[0046] The baffle 308b is used for blocking the inside of the fixed frame 308a, so as to avoid the situation that the connecting pipe 307 continuously delivers gas to the inside of the air inlet pipe 306, and the sharpener 301 excessively grinds the blade. When the motor 308c is started, the baffle 308b can be driven to open or close, so as to control the gas.

[0047] Specifically, the grinding assembly 300 further comprises a trigger 309, the trigger 309 comprises a positioning column 309a fixed on one side of the fixed frame 308a, a gear 309b rotatably connected to the outside of the positioning column 309a, a first electrode sheet 309c fixed on one side of the positioning column 309a, and a second electrode sheet 309d fixed on one side of the gear 309b through a fixed rod.

[0048] The positioning column 309a is used for supporting the gear 309b. When the gear 309b rotates, the second electrode sheet 309d is driven to rotate. When the second electrode sheet 309d contacts the first electrode sheet 309c, the motor 308c is delayed for a certain time to start. When the movable block 202 contacts the starting position of the blade, the motor 308c starts to drive the baffle 308b to open. When the baffle 308b is opened for a certain time, the movable block 202 moves to the starting position of the blade again, so that the sharpener 301 completes one grinding circle from the upper blade. The motor 308c drives the baffle 308b to close, so that the sharpener 301 loses the power clamped on the outside of the blade and separates from the blade. When the second electrode sheet 309d contacts the first electrode sheet 309c again, the motor 308c can repeat the above operation.

[0049] Specifically, a rotating sleeve 309e is rotatably connected to one side of the fixed frame 308a through a bearing, a moving column 309f is inserted into the rotating sleeve 309e, a fixed shaft 309g is fixed in the rotating sleeve 309e, a spiral groove 309f-1 is formed in the moving column 309f, the fixed shaft 309g slides in the spiral groove 309f-1, a reset groove 309f-2 is formed in the moving column 309f and communicates with the spiral groove 309f-1, an insertion slot 309e-1 is formed in the rotating sleeve 309e, a tooth block 309h is inserted into the insertion slot 309e-1, a push column 309i is fixed on one side of the movable block 202, and the push column 309i cooperates with the moving column 309f.

[0050] The reset slot 309f-2 is linear, when the movable block 202 moves along the blade-shaped track, and the push column 309i is in contact with the moving column 309f, at this time the moving column 309f pushes the push column 309i to move, when the push column 309i moves, the fixed shaft 309g slides along the inner wall of the spiral slot 309f-1, and through the cooperation of the two, the rotating sleeve 309e rotates one revolution, at this time the rotating sleeve 309e drives the gear 309b to rotate a small angle through the tooth block 309h, at the same time, the fixed shaft 309g will enter the reset slot 309f-2, when the push column 309i is separated from the moving column 309f, at this time the moving column 309f will reset, and the fixed shaft 309g resets along the direction of the reset slot 309f-2.

[0051] With the movable block 202 continuously driving the push column 309i to press the moving column 309f, the push column 309i presses the moving column 309f once, which means that the knife roller 103 rotates one revolution, and under the condition that the knife roller 103 rotates one revolution, the gear 309b will only rotate a small angle, only when the knife roller 103 is used for a long time, the gear 309b will drive the second electrode sheet 309d to contact the first electrode sheet 309c, and the gas can enter the gas inlet pipe 306, and then the knife can be ground by the knife sharpener 301, so that the knife can be ground at the right time without observing the wear degree of the knife frequently.

[0052] Specifically, the fixed frame 308a is fixed on one side of the limiting rod 309j, and the limiting rod 309j is movably connected in the moving column 309f, and the limiting rod 309j is rectangular.

[0053] The limiting rod 309j is used for limiting the moving column 309f to avoid rotation of the moving column 309f when moving.

[0054] Specifically, the limiting rod 309j is provided with a first spring 309k outside, and the two ends of the first spring 309k are fixed with the moving column 309f and the fixed frame 308a respectively.

[0055] The first spring 309k applies a pushing force to the moving column 309f, so that it can reset after moving.

[0056] Embodiment 3

[0057] Reference Figures 1-9 This embodiment is based on the previous two embodiments.

[0058] Specifically, the fixed column 303 is provided with a second spring 310 outside, and the two ends of the second spring 310 are fixed with the stress plate 305 and the inner wall of the gas chamber 202-1 respectively.

[0059] When the air intake pipe 306 stops air intake, the force receiving plate 305 can be moved by the second spring 310 to push, so that the force receiving plate 305 drives the fixed column 303 and the supporting rod 302 to reset, and the knife sharpener 301 is separated from the blade.

[0060] Specifically, the connecting part of the spiral groove 309f-1 and the reset groove 309f-2 is provided with a limiting step 309f-3 for blocking the fixed shaft 309g.

[0061] Through the setting of the limiting step 309f-3, when the push column 309i pushes the moving column 309f to move, the limiting step 309f-3 can block the fixed shaft 309g at this time, so that the fixed shaft 309g will not move along the reset groove 309f-2, but will move along the spiral groove 309f-1, thereby avoiding the rotation of the rotating sleeve 309e.

[0062] Specifically, the middle part of the air intake pipe 306 and the air suction pipe 206 is a telescopic bellows.

[0063] By setting the air intake pipe 306 and the air suction pipe 206 as telescopic bellows, the movement of the movable block 202 can be adapted.

[0064] Specifically, the number of the slot 309e-1 is multiple, which is evenly distributed on the rotating sleeve 309e in an arc shape. Through the setting of multiple slots 309e-1, the number of the tooth block 309h can be increased or decreased, thereby the time interval of the second electrode plate 309d contacting the first electrode plate 309c can be adjusted, and the frequency of the blade grinding can be adjusted.

[0065] In use, when the knife roller 103 rotates, the cleaning block 204 can clean the blade on the knife roller 103, and the movable block 202 is driven to move by the air cylinder 208, and the sleeve 203 and the cleaning block 204 are driven to move by the movable block 202, so that the cleaning block 204 can adapt to different trajectories of the blade, and when the blade is curved, the cleaning block 204 can also adaptively rotate. When the cleaning block 204 moves to the end position of the blade, with the rotation of the knife roller 103, because the cleaning block 204 is relatively soft, the cleaning block 204 will pass the end of the blade and be clamped in the starting position of the blade again, and continue to clean the blade.

[0066] The suction pump 207 generates suction in the air suction pipe 206, at this time, the impurities cleaned inside the cleaning block 204 will move to the inside of the sleeve 203 under the action of the suction, and then enter the connecting sleeve 205 through the discharge hole 203-1, and then be sucked away by the air suction pipe 206 and transported to the designated position, so as to avoid the impurities inside the cleaning block 204 from being attached to the blade again.

[0067] When the movable block 202 moves along the trajectory of the blade shape and drives the push column 309i to contact the moving column 309f, the moving column 309f pushes the push column 309i to move, and when the push column 309i moves, the fixed shaft 309g slides along the inner wall of the spiral groove 309f-1, drives the rotating sleeve 309e to rotate one circle, and at this time, the rotating sleeve 309e drives the gear 309b to rotate a small angle through the gear block 309h, and when the gear 309b rotates, it drives the second electrode sheet 309d to rotate, and when the second electrode sheet 309d contacts the first electrode sheet 309c, the motor 308c is delayed to start for a certain time, and when the movable block 202 contacts the starting position of the blade, the motor 308c starts to drive the baffle 308b to open, and when the baffle 308b is opened for a certain time, the motor 308c drives the baffle 308b to close after the movable block 202 moves to the starting position of the blade again, so that the knife sharpener 301 loses the power connected to the outside of the blade and separates from the blade, and when the second electrode sheet 309d contacts the first electrode sheet 309c again, the motor 308c can repeat the above operation.

[0068] With the movable block 202 continuously driving the push column 309i to extrude the moving column 309f, the push column 309i extrudes the moving column 309f once, which means that the knife roller 103 rotates one circle, and under the condition that the knife roller 103 rotates one circle, the gear 309b only rotates a small angle, and only when the knife roller 103 is used for a long time, the gear 309b drives the second electrode sheet 309d to contact the first electrode sheet 309c, and gas can enter the gas inlet pipe 306, so that the knife sharpener 301 can grind the blade, and the blade can be ground at the right time without observing the wear degree of the blade manually.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application, which should be covered by the claims of the present application.
