[0095] See also Figure 1 , Figure 2 and Figure 3, the embodiment of the present application provides a grinder 10. The grinder 10 includes a base 1000, a grinding cup 300, a grinding cup cover 320, a grinding tool 500, a column 940, a power device 800 and a clamping sensor 650. The base 1000 may be a circular base. It plays a supporting role. The grinding cup 300 is arranged on the base 1000. The grinding cup cover 320 is buckled on the cup mouth of the grinding cup 300. The grinding cup cover 320 can be used to prevent the material in the grinding cup 300 from splashing. The grinding tool 500 includes a tool rod 520 and a blade 510. The tool rod may be a cylindrical structure. The tool rod 520 passes through the grinding cup cover 320. In one embodiment, the grinding cup cover 320 may be provided with a tool centering hole 330. The tool centering hole 330 may be located at the center of the grinding cup cover 320. The tool rod 520 can freely pass through the tool centering hole 330. The blade 510 is disposed at one end of the knife bar 520 located in the grinding cup 300. The blade 510 may be one or more, and the blade 510 is used to stir and cut materials. A sensing area 530 is disposed at one end of the knife bar 520 away from the blade 510. When the sensing area 530 reaches a specific position, it can be sensed by the clamping sensor 650, so that the clamping sensor 650 outputs a signal.

[0096] The column 940 is disposed on the base 1000. The column 940 can be vertically disposed on the base 1000. The power device 800 is movably disposed on the column 940 along the vertical direction and is located above the grinding cup 300. The power device 800 can move up and down along the column 940 under the drive of the driving motor 900. The power device 800 can be a rotary motor.

[0097] The power device 800 is provided with a clamping hole 810 at one end close to the grinding cup 300. The clamping hole 810 can be used to clamp the knife bar 520. Then the power device 800 can drive the knife bar 520 to rotate. The clamping sensor 650 is provided at one end of the power device 800 close to the grinding cup 300. The clamping sensor 650 can be a capacitive sensing element, an inductive sensing element, an infrared sensing element, etc. When the knife bar 520 enters the clamping hole 810 so that the sensing area 530 reaches a specific position, the clamping sensor 650 can output a signal to the power device 800 after sensing the sensing area 530. The power device 800 can control the clamping hole 810 to clamp the knife bar 520. The specific position is the position where the clamping hole 810 can safely and firmly grasp the knife bar 520.

[0098] It is understood that the structure and principle of the clamping hole 810 clamping the tool bar 520 can be the same as the structure and principle of an electric drill grasping a drill bit. No further details are given here. In one embodiment, the clamping hole 810 can also be pneumatically controlled to clamp the tool bar 520.

[0099] When the power device 800 moves vertically downward, the end of the knife bar 520 away from the blade 510 enters the clamping hole 810, and the clamping sensor 650 sends a signal to the power device 800 when sensing the sensing area 530, and the power device 800 controls the clamping hole 810 to clamp the knife bar 520. The grinding tool 500 can be used in conjunction with the grinding cup 300. Each grinding cup 300 can be used in conjunction with one grinding tool 500, so cross-infection of materials can be avoided. Further, the position of the knife bar 520 is determined by sensing the sensing area 530 through the clamping sensor 650, and then the clamping hole 810 is automatically controlled to clamp the knife bar 520, which has high work efficiency and avoids the trouble of constantly manually adjusting the clamping position of the knife bar 520 when using grinding cups 300 of different heights and sizes, or different amounts of materials in the grinding cup 300 make the height of the knife bar 520 different.

[0100] In one embodiment, the grinding instrument 10 further includes a compacting cover 400, a ring 420, and a guide connecting rod 410. The compacting cover 400 is disposed in the grinding cup 300 and is located between the grinding cup cover 320 and the bottom of the grinding cup 300. The diameter of the compacting cover 400 may be slightly smaller than the diameter of the grinding cup 300. Therefore, the compacting cover 400 may slide on the inner wall of the grinding cup 300. The ring 420 may be an annular structure. The ring 420 is disposed between the grinding cup cover 320 and the power device 800. When the grinding cup 300 is installed below the power device 800, the power device 800 may first push the ring 420 when it moves toward the grinding cup 300. The guide connecting rod 410 passes through the grinding cup cover 320. The two ends of the guide connecting rod 410 are respectively connected to the compacting cover 400 and the ring 420. Therefore, the ring 420 can drive the compacting cover 400 to move downward.

[0101] It can be understood that there can be multiple guide connecting rods 410. There are also several positioning holes 340 on the grinding cup cover 320. Each positioning hole 340 can pass through a guide connecting rod 410. The two ends of each guide connecting rod 410 are respectively connected to the compacting cover 400 and the ring 420. Therefore, it can be ensured that the ring 420 and the compacting cover 400 move in the vertical direction when being pushed downward by the power device 800.

[0102] The power device 800 is provided with a tapered hole seat 600 at one end close to the clamping hole 810. The tapered hole seat 600 can be connected to the clamping hole 810, and the knife bar 520 can enter the clamping hole 810 through the tapered hole seat 600.

[0103] The conical hole seat 600 has a downward pressing surface 620. When the power device 800 moves downward, so that the downward pressing surface 620 pushes the ring 420, the ring 420 pushes the compacting cover 400 through the guide connecting rod 410, so that the compacting cover 400 can squeeze the material. It can be understood that when the material is crushed, the volume will become smaller and smaller, so the downward pressing surface 620 can continuously push the compacting cover 400 to move downward to compact the material. When the power device 800 moves downward, the blade 510 can also move downward, thereby grinding the material efficiently.

[0104] In one embodiment, the conical hole seat 600 is provided with a telescopic adjustment pin 630. The telescopic adjustment pin 630 extends from the lower pressing surface 620. When the lower pressing surface 620 moves downward, the telescopic adjustment pin 630 pushes the circular ring 420. The telescopic adjustment pin 630 can be a spring column or an elastic shaft. In a natural state, the telescopic adjustment pin 630 extends from the lower pressing surface 620. When the telescopic adjustment pin 630 pushes the circular ring 420, the telescopic adjustment pin 630 is compressed and partially retracted to the lower pressing surface 620 by pressure. Since the telescopic adjustment pin 630 can adjust its own length within a certain range after being subjected to different pressures, it can ensure that the compacting cover 400 can float up and down to a certain extent while the material is tumbling while pressing the material, so as to avoid crushing the material and affecting the tumbling of the material. It can be understood that the up and down floating distance of the compacting cover 400 can be the telescopic length of the telescopic adjustment pin 630.

[0105] The lower pressing surface 620 pushes the ring 420 through the retractable adjustment pin 630, and can press the compacting cover 400 toward the bottom of the grinding cup 300. The length of the guide connecting rod 410 can be set as needed to ensure that there is a suitable distance between the compacting cover 400 and the bottom of the grinding cup 300, so as to prevent the compacting cover 400 from colliding with the bottom of the grinding cup 300.

[0106] In one embodiment, the tapered hole seat 600 further includes a guide cone 610 and a guide hole 660. The lower pressure surface 620 is the lower end surface of the guide cone 610. The guide cone 610 can roughly adjust the position of the knife rod 520 so that the end of the knife rod 520 away from the blade 510 enters first, and helps the knife rod 520 to slide smoothly into the guide hole 660. The guide hole 660 extends in the vertical direction and connects the guide cone 610 and the clamping hole 810. The guide hole 660 can be a transition hole for the knife rod 520 to enter the clamping hole 810, so as long as the knife rod 520 enters the guide hole 660, it can smoothly enter the clamping hole 810. The knife rod 520 can enter the clamping hole 810 through the guide cone 610 and the guide hole 660 in sequence. The clamping sensor 650 is arranged on the inner wall of the guide hole 660. Therefore, when the sensing area 530 of the tool rod 520 enters the guiding hole 660 , it can be sensed by the clamping sensor 650 .

[0107] In one embodiment, a guide spherical surface 540 may be provided at one end of the knife rod 520 away from the blade 510 , so as to facilitate the knife rod 520 to enter the guide cone 610 .

[0108] In one embodiment, the grinding machine further includes an anti-collision convex point 640. The anti-collision convex point 640 is arranged on the inner surface of the guide hole 660. The anti-collision convex point 640 is used to prevent the knife bar 520 from touching the clamping sensor 650 when entering the guide hole 660. The anti-collision convex point 640 can push the knife bar 520 away from the inner wall of the guide hole 660, and prevent the knife bar 520 from being close to the inner wall of the guide hole 660, thereby ensuring that the knife bar 520 will not touch the clamping sensor 650 when passing through the clamping sensor 650, thereby protecting the clamping sensor 650 from being damaged by the knife bar 520.

[0109] In one embodiment, the grinder 10 further includes a disc worktable 200, an identification telescopic shaft 230 and an induction sensor 250. The disc worktable 200 is rotatably arranged on a side where the base 1000 is close to the power device 800. A plurality of positioning countersunk holes 210 are arranged circumferentially on the surface of the disc worktable 200 close to the power device 800. The positioning countersunk holes 210 may have a bottom. The positioning countersunk holes 210 are used to place the grinding cup 300, and the disc worktable 200 may be automatically controlled to rotate. Each of the positioning countersunk holes 210 may place one of the grinding cups 300. Different materials may be placed in each of the grinding cups 300, or different materials may be contained. After one of the grinding cups 300 rotates to the right below the power device 800, the disc worktable 200 may stop rotating. The power device 800 moves downward to grab the knife bar 520, and then starts grinding. When the material is ground, the disc worktable 200 may rotate to replace the next grinding cup 300 for grinding.

[0110] The identification telescopic shaft 230 passes through the bottom of the positioning countersunk hole 210. In a natural state, the end of the identification telescopic shaft 230 close to the base 1000 can be flush with the bottom of the positioning countersunk hole 210. The inductive sensor 250 is arranged between the disc worktable 200 and the base 1000. The inductive sensor 250 can be arranged at the position of the power device 800 corresponding to the position where the grinding cup 300 is placed. After the grinding cup 300 is placed in the positioning countersunk hole 210, the grinding cup 300 squeezes the identification telescopic shaft 230 so that the identification telescopic shaft 230 extends from the bottom of the positioning countersunk hole 210. When the positioning countersunk hole 210 rotates to the grinding position corresponding to the power device 800, the inductive sensor 250 senses the identification telescopic shaft 230, and outputs a signal to control the disc worktable 200 to stop rotating through the control device 120. It can be understood that the grinding position is the position where the grinding cup 300 is located when the power device 800 can grasp the knife rod 520 through the clamping hole 810 and grind the material in the grinding cup 300.

[0111] It is understandable that the control device 120 may include a control chip such as a PLC. The control device 120 may also control the working state of the power device 800.

[0112] When the grinding cup 300 is not placed in the positioning counterbore 210, the end of the identification telescopic shaft 230 close to the base 1000 can be flush with the bottom of the positioning counterbore 210. Therefore, when the positioning counterbore 210 without the grinding cup 300 is rotated to the grinding position, the inductive sensor 250 cannot sense the identification telescopic shaft 230. Therefore, the disc worktable 200 continues to rotate until the positioning counterbore 210 with the grinding cup 300 is rotated to the grinding position. Therefore, only when the identification telescopic shaft 230 extends from the bottom of the positioning counterbore 210 and rotates to the grinding position, the inductive sensor 250 can sense the identification telescopic shaft 230. The inductive sensor 250 can be an inductive sensor, a capacitive sensor, an infrared sensor, etc.

[0113] In one embodiment, when the identification telescopic shaft 230 extends from the bottom of the positioning countersunk hole 210 and turns to the top of the sensing sensor 250, the sensing distance is just within the sensing range of the sensing sensor 250. The sensing sensor 250 immediately outputs a signal to the control device 120. The control device 120 immediately stops the circular workbench 200 at this position, which is the grinding position.

[0114] In one embodiment, a guide hole 212 is provided at the bottom of the positioning counterbore 210. The guide hole 212 is used to pass the identification telescopic shaft 230. A retaining ring 214 is provided on the side wall of the identification telescopic shaft 230. A boss 216 is provided on the inner wall of the guide hole 212. A spring 240 is provided between the retaining ring 214 and the boss 216, that is, the two ends of the spring 240 are in contact with the boss 216 and the retaining ring 214 respectively.

[0115] When the grinding cup 300 is placed in the positioning counterbore 210, the grinding cup 300 squeezes the identification telescopic shaft 230 so that the identification telescopic shaft 230 extends from the bottom of the guide hole 212. The retaining ring 214 moves downward and compresses the spring 240. When the grinding cup 300 leaves the positioning counterbore 210, the identification telescopic shaft 230 is released, and when the spring 240 recovers its deformation, the retaining ring 214 pushes the identification telescopic shaft 230 to retract from the bottom of the guide hole 212.

[0116] In one embodiment, each of the positioning countersunk holes 210 includes a plurality of concentrically arranged step holes 218. The bottom of each of the step holes 218 passes through an identification telescopic shaft 230. The diameters of the step holes 218 are different. From the center of the positioning countersunk hole 210 to the edge of the positioning countersunk hole 210, the diameter of each of the step holes 218 can gradually increase. The size of each of the step holes 218 is adapted to the grinding cups 300 of different specifications. It can be understood that the diameter of the step hole 218 can be slightly larger than the diameter of the grinding cup 300, so that the grinding cup 300 can enter the step hole 218.

[0117] In one embodiment, the bottom of the grinding cup 300 is provided with a leg 310, and the bottom of the positioning countersunk hole 210 is provided with an anti-rotation hole 220. After the grinding cup 300 is placed in the positioning countersunk hole 210, the leg 310 enters the anti-rotation hole 220 to prevent the grinding cup 300 from rotating.

[0118] The inner diameter of the anti-rotation hole 220 is slightly larger than the outer diameter of the leg 310 at the bottom of the grinding cup 300. The distribution circle diameters of the anti-rotation hole 220 and the leg 310 are equal. After the grinding cup 300 is placed in the positioning counterbore 210, the grinding cup 300 is rotated until the leg 310 falls into the anti-rotation hole 220, so that the grinding cup 300 cannot rotate. The function of the anti-rotation hole 220 is to prevent the grinding cup 300 from rotating in the positioning hole 210. In one embodiment, there are at least three legs 310 on the outer side of the bottom of the grinding cup 300. Three anti-rotation holes 220 are provided corresponding to the bottom of the positioning counterbore 210.

[0119] In one embodiment, the grinding machine 10 further includes a bracket 260, a locking cylinder 280, a rotating shaft 270 and a rotating lever 290. The bracket 260 is arranged on the base 1000. The bracket 260 can be arranged perpendicular to the base 1000. The locking cylinder 280 is arranged on the bracket 260. The rotating shaft 270 is arranged on the bracket 260. The rotating lever 290 is rotatably arranged on the bracket 260 through the rotating shaft 270. One end of the rotating lever 290 is transmission-connected with the locking cylinder 280, and the other end is provided with a locking roller 291. The disc worktable 200 is provided with a locking groove 292. After the disc worktable 200 rotates to the set position, the locking cylinder 280 drives the rotating lever 290 to rotate around the rotating shaft 270, so that the locking roller 291 enters the locking groove 292 to fix the disc worktable 200. The set position can be the grinding position.

[0120] The rotating shaft 270 can be kept in a horizontal position. The locking cylinder 280 can drive the rotating lever 290 to rotate up and down around the rotating shaft 270. The width of the locking groove 292 can be slightly larger than the diameter of the locking roller 291, so that the locking roller 291 can enter the locking groove 292. The locking roller 291 and the locking groove 292 can be loosely matched. When the locking roller 291 enters the locking groove 292, the disc worktable 200 can be prevented from rotating and shaking.

[0121] It can be understood that when the sensing sensor 250 senses the identification telescopic shaft 230 and outputs a signal to control the disc worktable 200 to stop rotating through the control device 120, the control device 120 can further control the locking cylinder 280 to work so that the locking roller 291 enters the locking groove 292.

[0122] In one embodiment, the grinder 10 further includes a pressure claw 700. The pressure claw 700 can be slidably disposed on the column 940. The movement state of the pressure claw 700 can be controlled by the control device 120. When the grinding cup 300 moves to the grinding position, the locking roller 291 can first lock the disc worktable 200, and then the control device 120 controls the pressure claw 700 to move downward to press the grinding cup cover 320 to prevent the grinding cup 300 from shaking or tipping over during the grinding process. Subsequently, the power device 800 can move downward to clamp the knife bar 520 through the clamping hole 810 to start the grinding work.

[0123] In one embodiment, the grinding machine 10 further includes a screw 910, a holder 920, a guide rail 930 and a driving motor 900, one end of the screw 910 is connected to the rotating shaft of the driving motor 900, and the other end of the screw 910 can be fixed on the bearing seat. One end of the holder 920 is connected to the power device 800, and the other end is connected to the guide rail 930. The holder 920 can move up and down along the guide rail 930. The holder 920 is also matched with the screw 910, and the driving motor 900 can drive the holder 920 to move up and down along the guide rail 930 through the screw 910, so the holder 920 can move up and down with the power device 800. The guide rail 930 can be arranged in parallel with the column 940.

[0124] See also Figure 4 In one embodiment, the grinding machine 10 further comprises a housing 100 and a transparent protective door 110, wherein the transparent protective door 110 is hingedly connected to the housing 100. The transparent protective door 110 is convenient for operators to observe.

[0125] When the grinder 10 is in working state, the transparent protection door 110 should be closed. When the grinder 10 is in non-working state, the transparent protection door 110 can be opened to operate the inside of the grinder 10.

[0126] In one embodiment, the control device 120 is disposed on the housing 100, so it is also convenient to control the operation of the grinder 10. It can be understood that the entire working process can be automatically operated by a program set in the control device 120, or each working link of the grinder 10 can be manually controlled by the control device 120.
