[0022] Reference Figure 1 A fully automatic double-sided knife sharpening device according to an embodiment of the present invention includes a workbench 100, a loading mechanism 200, a grinding mechanism 300, and a unloading mechanism 400. The workbench 100 is provided with a first feeding station 101, a first material storage station for processing 102, a first grinding station 103, a first discharging station 104, a second feeding station 105, a second material storage station for processing 106, a second grinding station 107, and a second discharging station 108. There are two loading mechanisms 200, with the first feeding station 101 corresponding to one of the loading mechanisms 200 and the second feeding station 105 corresponding to the other of the loading mechanisms 200. There are two grinding mechanisms 300, with the first grinding station 103 corresponding to one of the grinding mechanisms 300 and the second grinding station 107 corresponding to the other of the grinding mechanisms 300. There are two unloading mechanisms 400, the first unloading station 104 corresponds to one of the unloading mechanisms 400, and the second unloading station 108 corresponds to the other grinding mechanism 300. The first material storage station 102 is located between the first feeding station 101 and the first unloading station 104, and the second material storage station 106 is located between the second feeding station 105 and the second grinding station 107.

[0023] The workflow of the fully automatic double-sided knife sharpening equipment of the embodiment of the present invention is as follows: the tool 500 of one loading mechanism 200 is transported to the first feeding station 101, then transferred to the first material storage and processing station 102 for waiting, then transferred to the first grinding station 103 for processing by one grinding mechanism 300. After processing, the tool 500 is transferred to the first discharge station 104 and finally transferred to one unloading mechanism 400 for storage. Similarly, the tool 500 of the other loading mechanism 200 is transported to the second feeding station 105, then transferred to the second material storage and processing station 106 for waiting, then transferred to the second grinding station 107 for processing by another grinding mechanism 300. After processing, the tool 500 is transferred to the second discharge station 108 and finally transferred to another unloading mechanism 400 for storage.

[0024] It can be seen that the fully automatic double-sided knife sharpening equipment of the embodiment of the present invention is equipped with two sets of loading mechanisms 200, grinding mechanisms 300 and unloading mechanisms 400, which can process two sets of cutting tools 500 at the same time. It adopts a double-station design to improve production efficiency and solve the problem of low production.

[0025] It is understandable that in some other embodiments, only one set of the loading mechanism 200 , the grinding mechanism 300 and the unloading mechanism 400 may be provided, or more than three sets may be provided.

[0026] Reference Figure 2 and Figure 3 The workbench 100 includes a base (not shown in the figure), a first drive mechanism (not shown in the figure), and a turntable 109. The turntable 109 is rotatably connected to the base. The first drive mechanism is used to drive the turntable 109 to rotate. The turntable 109 is provided with a clamping mechanism 600 for clamping the tool 500. The clamping mechanism 600 can clamp multiple types of tools 500. The turntable 109 is polygonal and is mounted on the base through a bearing. In some embodiments, the first drive mechanism is a stepper motor, which drives the small pulley to rotate. The turntable 109 is connected to the large pulley, and a synchronous belt connects the large pulley and the small pulley, so that the disk can be driven by the stepper motor for continuous feeding. As the turntable 109 rotates, the same clamping mechanism 600 sequentially reaches the first feeding station 101, the first material storage station for processing 102, the first grinding station 103, the first material discharge station 104, the second feeding station 105, the second material storage station for processing 106, the second grinding station 107, and the second material discharge station 108. The turntable 109 is provided with eight clamping mechanisms 600, ensuring that each station is provided with a clamping mechanism 600 as the turntable 109 rotates. This allows the loading mechanism 200, grinding mechanism 300, and unloading mechanism 400 to operate simultaneously, thereby improving work efficiency.

[0027] Reference Figure 4 and Figure 5 The loading mechanism 200 includes a loading storage bin 201 and a loading assembly. The loading assembly is used to transfer the tool 500 from the loading storage bin 201 to the clamping mechanism 600. The loading assembly includes a first conveying mechanism 202, a first turning mechanism 203, a first feeding mechanism 204, a conveyor belt 205 and a second conveying mechanism 206.

[0028] It is understood that multiple horizontally positioned cutting tools 500 are placed in the loading storage bin 201. The sidewalls of the loading storage bin 201 are provided with through slots. The loading storage bin 201 is connected to a lifting box 207, which is equipped with a servo motor. A lead screw is provided within the lifting box 207, which is connected to a lifting plate. The lifting plate passes through the through slots and enters the loading storage bin 201, with all the cutting tools 500 placed on the lifting plate. The servo motor drives the lead screw to rotate, thereby driving the lifting plate to move up and down along the through slots. When a cutting tool 500 is removed from the loading storage bin 201, the servo motor activates, causing the lifting plate to raise all the cutting tools 500, making it easier to access the cutting tools 500.

[0029] The first transport mechanism 202 can be configured as a first transport cylinder, and the second transport mechanism 206 can be configured as a second transport cylinder. The first transport cylinder and the second transport cylinder are located at both ends of the conveyor belt 205. The first transport cylinder can grab the tool 500 from the loading storage bin 201 and then transport it to the conveyor belt 205. The tool 500 is then transferred to the second transport cylinder via the conveyor belt 205. The second transport cylinder will grab the tool 500 on the conveyor belt 205 and place it on the first turning mechanism 203. In some embodiments, the first transport cylinder and the second transport cylinder are both provided with electromagnets to suck in or put down the tool 500.

[0030] Reference Figure 6 and Figure 7 The first flip mechanism 203 includes a flip plate 208 and a second driving mechanism. The second driving mechanism is used to drive the flip plate 208 to flip. The flip plate 208 includes a flat portion 209 and a bent portion 210. The bent portion 210 is connected to one side of the flat portion 209 and extends toward the other side of the flat portion 209. A first limiting groove 211 is formed between the bent portion 210 and the flat portion 209. Figure 4 , the opening of the first limiting groove 211 faces the conveyor belt 205, and the second transport cylinder places the tool 500 horizontally on the flip plate 208, and part of the tool 500 enters the first limiting groove 211. Figure 5 The second driving mechanism drives the tool 500 to flip 90 degrees, and the flip plate 208 drives the tool 500 to flip, so that the tool 500 is placed vertically.

[0031] Reference Figure 6The second driving mechanism includes a flip cylinder 212, a gear 213 and a rack 214. The gear 213 and the rack 214 are meshed. The rack 214 is connected to the push rod of the flip cylinder 212. The gear 213 is connected to the flip plate 208. The push rod of the flip cylinder 212 is extended and retracted to rotate the gear 213, thereby driving the flip plate 208 to flip, allowing the tool 500 to change its posture.

[0032] Reference Figures 4 to 6 The first feeding mechanism 204 includes a transverse feeding rail module 215 and a longitudinal feeding rail module 216. The transverse feeding rail module 215 and the longitudinal feeding rail module 216 are connected. The longitudinal feeding rail module 216 is provided with a loading mechanical clamp 217, which can clamp the tool 500. The longitudinal feeding rail module 216 drives the loading mechanical clamp 217 to move upward to avoid the first turning mechanism 203. The longitudinal feeding rail module 216 drives the loading mechanical clamp 217 to move downward to clamp the tool 500. The transverse feeding rail module 215 can drive the loading mechanical clamp 217 to move toward the clamping mechanism 600, so that the tool 500 is clamped by the clamping mechanism 600.

[0033] Reference Figures 8 to 10 The clamping mechanism 600 includes a fixed base 601, a movable base 602, and a third driving mechanism 603. The third driving mechanism 603 is used to drive the movable base 602 toward or away from the fixed base 601 to clamp or release the tool 500. When the third driving mechanism 603 drives the movable base 602 away from the fixed base 601, the gap between the fixed base 601 and the movable base 602 increases, allowing the tool 500 to be placed between the fixed base 601 and the movable base 602. When the third driving mechanism 603 drives the movable base 602 toward the fixed base 601, the gap between the fixed base 601 and the movable base 602 decreases, allowing the tool 500 to be clamped.

[0034] Reference Figure 11, a second limiting groove 604 is provided on the top of the fixed seat 601, and the second limiting groove 604 is used to accommodate part of the tool 500. The bottom wall of the second limiting groove 604 supports the tool 500 and positions the tool 500 in the height direction. The width of the second limiting groove 604 is adapted to the thickness of the blade back of the tool 500. The side wall height of the second limiting groove 604 on the side close to the movable seat 602 is relatively low, which can play a role of rough positioning and prevent the tool 500 from tipping toward the movable seat 602 (a small angle of tilt is allowed, but it will not fall). The side wall height of the second limiting groove 604 on the side away from the movable seat 602 is relatively high, which can play a limiting role, ensuring that the tool 500 can remain vertical when it is close to the side wall of this side. When the first feeding mechanism 204 transfers the tool 500 to the clamping mechanism 600, the back of the tool is placed toward the second limiting groove 604. After the back of the tool is placed in the second limiting groove 604, the tool 500 can be confined in the second limiting groove 604 and maintain a basically vertical state, thereby completing the pre-fixation of the tool 500, facilitating the subsequent movable seat 602 and the fixed seat 601 to cooperate in clamping the tool 500.

[0035] Reference Figures 8 to 10 and Figure 12 A pressure block 605 is provided on top of the movable seat 602 to limit the upward movement of the handle of the tool 500. When the third drive mechanism 603 drives the movable seat 602 toward the fixed seat 601 and clamps the tool 500, the bottom surface of the pressure block 605 abuts the top surface of the handle, thereby limiting the upward position of the tool 500 and preventing the tool 500 from tilting along the vertical plane during grinding.

[0036] Refer to 10 to Figure 12 The tool 500 is provided with a limiting hole 501, and the movable seat 602 is provided with a limiting shaft (not shown in the figure), which is passed through the limiting hole 501. The limiting shaft cooperates with the limiting hole 501 to limit the movement of the tool 500 along the length direction of the second limiting groove 604, thereby ensuring that the tool 500 does not affect the grinding accuracy due to movement during grinding.

[0037] Referring to Figure 10 , the clamping mechanism 600 includes a first mounting seat 606 and a second mounting seat 607. The fixed seat 601 is fastened to the first mounting seat 606 by screws 608. The first mounting seat 606 is provided with a slide rail 609, and the movable seat 602 is provided with a slide groove 610 that cooperates with the slide rail 609. That is, the same set of fixed seat 601 and movable seat 602 are integrated into the first mounting seat 606. The third driving mechanism 603 is mounted on the second mounting seat 607. The first mounting seat 606 is detachably connected to the second mounting seat 607, facilitating the rapid replacement of different molds, improving the compatibility of the types of products processed by the tool 500, reducing assembly time, and improving production efficiency.

[0038] Refer to 10 and Figure 12The second mounting seat 607 is provided with a slot 611, and the first mounting seat 606 is slidably mounted in the slot 611. The slot 611 has a closed end 612 and an open end 613. The first mounting seat 606 enters the open end 613 of the slot 611 and is restrained by the closed end 612. The first mounting seat 606 is provided with a wedge surface 614, and the second mounting seat 607 is provided with a wedge locking device, which includes a wedge block 615 and a first adjustment screw 616. The second mounting seat 607 is provided with a sliding seat 617, which is adjacent to the open end 613. The wedge block 615 is slidably mounted in the sliding seat 617. The first adjustment screw 616 is connected to the sliding seat 617 via a nut 620 to adjust the position of the wedge block 615. During installation, after the first mounting seat 606 is inserted into the slot 611, the first adjusting screw 616 is rotated to push out the wedge block 615, so that the wedge block 615 is used to press the wedge surface 614, thereby fixing the two ends of the first mounting seat 606, so that the first mounting seat 606 is fixed in the slot 611. During disassembly, the first adjusting screw 616 is rotated in the opposite direction to move the wedge block 615 into the sliding seat 617 to avoid the first mounting seat 606, and then the first mounting seat 606 is moved toward the open end 613. Finally, the first mounting seat 606 is separated from the open end 613 and the slot 611 is disassembled.

[0039] Reference Figures 8 to 10 and Figure 12 The second mounting seat 607 is provided with an adjustment plate 618 and a second adjustment screw 619. The adjustment plate 618 is slidably connected to the second mounting seat 607. The third drive mechanism 603 is mounted on the adjustment plate 618. The second adjustment screw 619 is connected to the second mounting seat 607 and is used to adjust the position of the adjustment plate 618. The sliding direction of the adjustment plate 618 is the same as the sliding direction of the movable seat 602. By providing an adjustable adjustment plate 618, it can be adjusted according to the thickness of the cutting tool 500, ensuring flexibility in the processing of the cutting tool 500. In some embodiments, the second mounting seat 607 is provided with a guide groove 621, and the adjustment plate 618 is slidably disposed in the guide groove 621.

[0040] The clamping mechanism 600 comprises a fixed base 601, a movable base 602, a third drive mechanism 603, an adjustment slide 618, and a second adjustment screw 619. By employing a combination of a first mounting base 606 detachably connected to a second mounting base 607 and an adjustment slide 618 slidably connected to the second mounting base 607, the system enables rapid switching of workpiece molds to meet varying workpiece processing requirements, improving adaptability and work efficiency. Its modular design allows for rapid adjustment of the number and function of workstations, enabling rapid fixture replacement, and reducing changeover time to minutes, enabling the production of a wide variety of medium and small batches.

[0041] Reference Figures 13 to 15The grinding mechanism 300 includes a bracket 301, a front-back drive mechanism 302, a left-right drive mechanism 303, a top-bottom drive mechanism 304, a first grinding head assembly 305, and a second grinding head assembly 306. The first grinding head assembly 305 and the second grinding head assembly 306 are arranged horizontally and side by side in the left-right direction. During grinding, the tool 500 is located between the first grinding head assembly 305 and the second grinding head assembly 306, so that both sides of the cutting surface of the tool 500 can be processed simultaneously. The front-back drive mechanism 302 is used to drive the first grinding head assembly 305 and the second grinding head assembly 306 to move in the front-back direction. That is, the front-back drive mechanism 302 causes the first grinding head assembly 305 and the second grinding head assembly 306 to grind the tool 500 along the X-axis direction. The left-right drive mechanism 303 is used to drive the first grinding head assembly 305 and the second grinding head assembly 306 to move in the left-right direction. The first grinding head assembly 305 and the second grinding head assembly 306 move independently, that is, the left-right drive mechanism 303 enables the first grinding head assembly 305 and the second grinding head assembly 306 to move in the Z-axis direction to adjust to the different thicknesses of the tools 500. The up-down drive mechanism 304 is used to drive the first grinding head assembly 305 and the second grinding head assembly 306 to move in the up-down direction, that is, the up-down drive mechanism 304 enables the first grinding head assembly 305 and the second grinding head assembly 306 to grind the tool 500 in the Y-axis direction.
