The grinding ceramic chips; by setting the vertical plate 24 that can move forward and backward, when the vertical plate 24 moves forward, the ceramic chip at the bottom of the storage rack 32 can be pushed, so that the ceramic chip reaches the front end position of the grinding table 22, that is, the specified position; by setting the pressing plate 14 that can move up and down, when the pressing plate 14 moves downward, the grinding belt 6 can be pressed downward, so that the grinding belt 6 contacts the ceramic chip, and the ceramic chip can be ground when the grinding belt 6 moves; the ceramic chips can be automatically ground throughout the whole process, replacing manual operation, reducing human resource occupation and improving grinding efficiency.

[0033] The support frame 3 is rotatably connected to a plurality of pulleys, and a grinding belt 6 is sleeved on the outer surfaces of the plurality of pulleys. The support frame 3 is also fixedly connected to two first motors 4, and the pulleys include a driving pulley 5 and a driven pulley 7, and the driving pulleys 5 are respectively fixedly connected to the corresponding first motors 4.

[0034] like Figure 1-Figure 3 As shown, the driving pulley 5 and the driven pulley 7 are rotatably connected to the support frame 3 through a rotating shaft. The function of the first motor 4 is to provide rotational force for the driving pulley 5. When the driving pulley 5 rotates, it can drive the grinding belt 6 to move and the driven pulley 7 to rotate. The motor is a prior art and will not be described in detail. The support frame 3 includes a front support frame 3 and a rear support frame 3. The rear support frame 3 is fixed to the operating table 1, and the front support frame 3 is installed at the front end of the rear support frame 3. The front support frame 3 can be disassembled to facilitate the replacement of the grinding belt 6.

[0035] A U-shaped frame 11 is fixedly connected to the upper end surface of the operating table 1, a U-shaped seat 12 is fixedly connected to the U-shaped frame 11, an L-shaped pressure rod 13 is slidably connected to the inner wall of the U-shaped seat 12, the pressure plate 14 is fixedly connected to the lower end of the L-shaped pressure rod 13, a second motor 8 is fixedly connected to the lower end surface of the operating table 1, a cylindrical cam 9 is fixedly connected to the output end of the second motor 8, and a third sliding pin 10 matching the cylindrical cam 9 is fixedly connected to the front end surface of the L-shaped pressure rod 13.

[0036] like Figure 4-Figure 5As shown, the function of the second motor 8 is to provide a rotational force for the cylindrical cam 9, the U-shaped frame 11 supports and fixes the U-shaped seat 12, and the L-shaped pressure rod 13 can be slidably connected to the inner wall of the U-shaped seat 12 up and down, that is, the third sliding pin 10 and the pressure plate 14 can only move up and down; through the engagement of the third sliding pin 10 with the cylindrical cam 9, the third sliding pin 10 can be driven to move intermittently upward or downward when the cylindrical cam 9 rotates, that is, when the cylindrical cam 9 rotates, through the engagement with the third sliding pin 10, the third sliding pin 10, the L-shaped pressure rod 13, and the pressure plate 14 can move downward, and can intermittently stop after moving downward to the bottom position. When the cylindrical cam 9 continues to rotate, the third sliding pin 10, the L-shaped pressure rod 13 and the pressing plate 14 can move upward to the top position. When the pressing plate 14 moves upward, it no longer squeezes the polishing belt 6 and can be out of contact with the polishing belt 6. At this time, the polishing belt 6 resets upward under its own elastic action and is out of contact with the ceramic chip. At this time, it is convenient to replace a new ceramic chip for polishing again. The cylindrical cam 9 and the third sliding pin 10 cooperate to make the pressing plate 14 move up and down intermittently.

[0037] The inner wall of the U-shaped seat 12 is also slidably connected to a spring push plate 16, the lower end surface of the spring push plate 16 is fixedly connected to a first spring 15, the lower end of the first spring 15 is fixedly connected to the L-shaped pressure rod 13, the upper inner wall of the spring push plate 16 is rotatably connected to a first threaded rod 17, the first threaded rod 17 is threadedly connected to the inner wall of the U-shaped seat 12, and the upper end surface of the first threaded rod 17 is fixedly connected to a rotatable first handle 18.

[0038] like Figure 4-Figure 5As shown, the spring push plate 16 can be slidably connected to the inner wall of the U-shaped seat 12 up and down, and the first handle 18 that can rotate is provided to facilitate driving the first threaded rod 17 to rotate. The first threaded rod 17 is threadedly connected to the U-shaped seat 12, and can move upward or downward when the first threaded rod 17 rotates. When the first threaded rod 17 moves upward or downward, it can drive the spring push plate 16 to move upward or downward, and when the first threaded rod 17 does not rotate, it has a self-locking function under the threaded connection between the first threaded rod 17 and the U-shaped seat 12, and the corresponding spring push plate 16 is in a fixed position. The first spring 15 always has a downward driving force on the L-shaped pressure rod 13, even if the third sliding pin 10 and the pressure plate 14 have a downward driving force under normal conditions, when the cylindrical cam 9 rotates to make the third sliding pin 10 move downward When moving, the first spring 15 can have a downward extrusion force on the L-shaped pressure rod 13 and the pressure plate 14, so that the pressure plate 14 has a downward extrusion force on the polishing belt 6, so that the polishing belt 6 can be more uniform and stable when contacting and polishing the ceramic chip. When the first handle 18 and the first threaded rod 17 are rotated, the spring push plate 16 can be driven to move downward or upward. When the spring push plate 16 moves downward, the first spring 15 can be compressed again. The first spring 15 will have a greater driving force on the L-shaped pressure rod 13 and the pressure plate 14, that is, the force of the pressure plate 14 to squeeze the polishing belt 6 becomes larger. Similarly, when the spring push plate 16 moves upward, the first spring 15 can be released. At this time, the force of the pressure plate 14 to squeeze the polishing belt 6 will become smaller, and the adaptive extrusion force can be adjusted according to the needs of polishing ceramic chips.

[0039] The lower end of the cylindrical cam 9 is coaxially fixed with a first disc cam 19 , the front end surface of the vertical plate 24 is fixed with an extension rod 21 , and the front end inner wall of the extension rod 21 is fixed with a first sliding pin 20 that matches the first disc cam 19 .

[0040] like Figure 7 As shown, the lower end of the vertical plate 24 can be slidably connected to the upper end surface of the operating table 1, and the upper end of the vertical plate 24 can be slidably connected to the inner wall of the grinding table 22. The first disc cam 19 can keep synchronous rotation with the cylindrical cam 9. When the first disc cam 19 rotates, the first sliding pin 20 can be driven to move back and forth for a stroke and then stop intermittently through the engagement with the first disc cam 19, that is, the first sliding pin 20, the extension rod 21, and the vertical plate 24 can move back and forth for a stroke and then stop intermittently once.

[0041] The inner wall of the upper end of the vertical plate 24 is slidably connected with a shift plate 25, and the inner wall of the lower end of the shift plate 25 is fixedly connected with a movable pin 26. The end surfaces of both sides of the vertical plate 24 are slidably connected with guide seats 27. The guide seats 27 are provided with an upper transverse groove 28, a first inclined groove 29 and a lower transverse groove 30 that match the movable pin 26. The front and rear sides of the lower end surface of the grinding table 22 are respectively fixedly connected with baffles 34 that match the guide seats 27.

[0042] like Figure 9-10 As shown, the dial plate 25 can be slidably connected to the inner wall of the vertical plate 24, and long key grooves are also provided on the end surfaces of both sides of the vertical plate 24. The movable pin 26 is slidably connected to the inner wall of the long key groove, and the guide seat 27 is slidably connected to the left and right end surfaces of the vertical plate 24. The guide seat 27 has a certain friction with the vertical plate 24. When the front end of the vertical plate 24 moves, the guide seat 27 can be driven to move forward and backward. When the guide seat 27 is not subjected to force, it can be stable on the vertical plate 24; the movable pin 26, the upper transverse groove 28, the first inclined groove 29, and the lower transverse groove 30 are installed and shaped as shown in FIG. Fig.10 As shown, when the live pin 26 is on the inner wall of the upper transverse groove 28, the live pin 26 and the paddle 25 can be at the topmost position and stable, that is, the live pin 26 and the paddle 25 will not move up and down. When the live pin 26 is on the inner wall of the lower transverse groove 30, the live pin 26 and the paddle 25 can be at the bottommost position and stable, that is, the live pin 26 and the paddle 25 will not move up and down. When the live pin 26 is engaged with the inner wall of the first inclined groove 29, the guide seat 27 moves forward or backward at this time, which can make the live pin 26 and the paddle 25 move upward or downward. Through the cooperation of the baffle 34 and the guide seat 27, when When the vertical plate 24 moves forward, it can drive the guide seat 27 and the dial plate 25 to move forward synchronously. The forward movement of the dial plate 25 can drive the ceramic chip to move forward. When the dial plate 25, the guide seat 27, etc. move forward to the specified position, that is, the guide seat 27 meets the baffle 34 at the front end, at this time, the baffle 34 can prevent the guide seat 27 from moving forward. When the vertical plate 24, the dial plate 25, the live pin 26, etc. continue to move forward, the live pin 26 can slide from the inner wall of the upper transverse groove 28 to the inner wall of the first inclined groove 29 and the lower transverse groove 30. When the live pin 26 slides forward on the inner wall of the first inclined groove 29 When the movable pin 26 and the paddle plate 25 move forward and downward at the same time, when the movable pin 26 enters the inner wall of the lower transverse groove 30, the paddle plate 25 can move downward to the inner wall of the vertical plate 24. At this time, the movable pin 26 and the paddle plate 25 are at the lowest position and are in a stable state. When the vertical plate 24 moves backward, the guide seat 27, the movable pin 26, the paddle plate 25, etc. can be driven to move backward synchronously. At this time, the paddle plate 25 is at the lowest position and will not meet the ceramic chip. When the vertical plate 24, the guide seat 27, etc. move backward to the specified position, that is, the guide seat 27 and the rear end When the baffle 34 meets, the vertical plate 24, the movable pin 26, the paddle plate 25, etc. continue to move backward, and the movable pin 26 will slide from the inner wall of the lower transverse groove 30 to the inner wall of the first inclined groove 29 and the upper transverse groove 28, that is, the movable pin 26 and the paddle plate 25 will move upward and backward at the same time, and the paddle plate 25 can be moved out to the upper end position of the vertical plate 24, and under the engagement of the movable pin 26 and the upper transverse groove 28, the paddle plate 25 is highly stable on the inner wall of the vertical plate 24. When the vertical plate 24 and the paddle plate 25 continue to move forward, the paddle plate 25 will push the next ceramic chip forward, so that the ceramic chip is pushed to the specified position.

[0043] The storage rack 32 is provided with a discharge port 33 at the lower end thereof, and the upper end surface of the grinding table 22 is fixedly connected to limit bars 31 on both sides thereof.

[0044] like Figure 8 As shown, through the provided discharge port 33, when the vertical plate 24 and the paddle plate 25 move forward, the ceramic chips at the bottom of the storage rack 32 can be pushed out, and through the provided limit strip 31, the ceramic chips can be limited to move forward and backward on the grinding table 22 to prevent deflection, and can also prevent the ceramic chips from moving during grinding; when the vertical plate 24 moves from back to front, the paddle plate 25 is at the topmost state, and the vertical plate 24 and the paddle plate 25 move forward to drive the ceramic chips to be ground at the bottom of the storage rack 32 to move forward. When the ceramic chips to be ground completely leave the storage rack 32, the ceramic chips stored inside the storage rack 32 will fall under the action of gravity, and the ceramic chips at the front end of the grinding table 22 The polished ceramic chips will be pushed forward of the polishing table 22 by the ceramic chips to be polished. The polished ceramic chips will fall into the designated position, that is, the material receiving box 50, under the action of weight. When the vertical plate 24 and the paddle plate 25 move forward to the designated position, that is, after the ceramic chips to be polished are pushed to the designated position, the paddle plate 25 will move downward to the bottom position. When the vertical plate 24 moves backward to reset, the paddle plate 25 will no longer meet the ceramic chips in the storage rack 32. When the paddle plate 25 moves backward to the top position, it will move upward again. When it moves forward again, it can drive the next ceramic chip to move forward to the designated position, thereby completing the loading and unloading work in a cycle.

[0045] A spur rack 35 is fixedly connected to the end face of one side of the extension rod 21, and a driving seat 39 is slidably connected to the upper end of the operating table 1. A second threaded rod 37 is also rotatably connected to the upper end of the operating table 1. A one-way transmission gear 36 meshing with the spur rack 35 is provided on the outer surface of the second threaded rod 37, and two incomplete threaded seats 40 matching the second threaded rod 37 are provided on the inner wall of the driving seat 39, and a material receiving box 50 is installed on the driving seat 39.

[0046] like Figure 11-Figure 14As shown, the material receiving box 50 is used to receive the polished ceramic chips, and the straight rack 35 can move back and forth with the extension rod 21. Two long guide rods 38 are fixedly connected to the upper end surface of the operating table 1, and the driving seat 39 is slidably connected to the outer surfaces of the two long guide rods 38 front and back. The limited driving seat 39 can only move forward and backward, which is equivalent to the driving seat 39 being slidably connected to the upper end of the operating table 1; the left and right ends of the outer surface of the second threaded rod 37 are rotatably connected with bearing seats, and the bottom end of the bearing seat is fixedly connected to the upper end surface of the operating table 1, and the limited second threaded rod 37 can only rotate at the upper end of the operating table 1; the one-way transmission gear 36 is provided with a ratchet, a pawl, and a flywheel mechanism similar to that on a bicycle, which can drive the second threaded rod 37 to rotate in one direction, that is, when the extension rod 21, the vertical plate 24, and the straight rack 35 move backward, at this time the dial plate 25 is in the backward reset process, and the one-way transmission gear 36 can drive the second threaded rod 37 to rotate, and when the extension rod 21, the vertical plate 24, and the straight rack 35 move forward, at this time the dial The plate 25 pushes the ceramic chips to unload, and the one-way transmission gear 36 no longer drives the second threaded rod 37 to rotate; when the second threaded rod 37 rotates, the incomplete threaded seat 40 and the second threaded rod 37 are threadedly connected, which can drive the incomplete threaded seat 40 and the driving seat 39 to move to one side. When the driving seat 39 moves to one side, it can drive the material receiving box 50 to move to one side. Therefore, when the extension rod 21 moves forward, the vertical plate 24 and the paddle plate 25 can drive the ceramic chips to move forward to unload, and the ceramic chips can fall into the material receiving box 50. At this time, the material receiving box 50 will not move forward. When the extension rod 21 moves backward to reset the vertical plate 24 and the paddle plate 25, the corresponding second threaded rod 37 can rotate, the driving seat 39 and the material receiving box 50 can move forward. When the material receiving box 50 moves forward, the material receiving position can be changed, so that the material receiving box 50 can be loaded more, that is, during unloading, the material receiving box 50 can intermittently move slowly to one side, and can evenly receive the loaded ceramic chips.

[0047] The incomplete thread seat 40 is slidably connected to the inner walls at the front and rear ends of the driving seat 39, and the inner walls at the front and rear ends of the driving seat 39 are respectively fixed with second springs 41 that match the incomplete thread seat 40, and the incomplete thread seat 40 is respectively fixed with a second handle 42.

[0048] like Fig.13 As shown, the incomplete thread seat 40 can be slidably connected to the inner wall of the driving seat 39 forward and backward, and the second spring 41 always has an inward thrust on the incomplete thread seat 40, so that the incomplete thread seat 40 can be in the innermost end position under normal conditions, so that the incomplete thread seat 40 and the second threaded rod 37 are stably engaged. By setting the second handle 42, the two incomplete thread seats 40 can be driven to move outward. When the incomplete thread seat 40 moves outward, it can be disengaged from the second threaded rod 37. At this time, the driving seat 39 can move to the left or right to the top position and reset to the initial state.

[0049] A tray 49 is slidably connected to the upper end surface of the driving seat 39, and a material receiving box 50 is placed on the inner wall of the tray 49. A second disc cam 43 is coaxially fixed to the upper end of the first disc cam 19. A T-shaped plate 47 is also slidably connected to the upper end of the operating table 1. A second sliding pin 46 is fixed to the inner wall of the front end of the T-shaped plate 47. An arc groove 44 and a wave groove 45 matching the second sliding pin 46 are formed on the second disc cam 43. The tray 49 is slidably connected to the rear end surface of the T-shaped plate 47.

[0050] like Figure 11-Figure 14 As shown, the tray 49 is slidably connected to the driving seat 39 front and back. When the driving seat 39 moves to the left or right, the tray 49 can be driven to move to the left or right, and the tray 49 and the material collection box 50 can move forward and backward on the driving seat 39. A card slot is provided on the upper end of the tray 49, and the material collection box 50 is placed on the inner wall of the card slot, so that the material collection box 50 can stably follow the tray 49 to move left and right or forward and backward, and the material collection box 50 can be removed and replaced when it is fully loaded; two brackets 48 are fixed to the upper end surface of the operating table 1, and the T-shaped plate 47 is slidably connected to the bracket 48 front and back. The limiting T-shaped plate 47 can only move forward and backward, which is equivalent to the T-shaped plate 47 being slidably connected to the upper end of the operating table 1, and the tray 49 can be slidably connected to the T-shaped plate 47 left and right, that is, it does not affect the tray 49 to move left and right following the driving seat 39, and when the T-shaped plate 47 moves back and forth, it can drive the tray 49 to move forward and backward; the second sliding pin 46, the arc groove 44, and the wave groove 45 are installed and shaped as shown in Fig.14As shown, under the meshing of the second sliding pin 46 and the arc groove 44, when the second disc cam 43 rotates, the corresponding second sliding pin 46 and T-shaped plate 47 will not move forward and backward. When the second sliding pin 46 is meshed with the wave groove 45, the rotation of the second disc cam 43 will drive the corresponding second sliding pin 46 and T-shaped plate 47 to reciprocate and oscillate. The reciprocating and oscillating movement of the T-shaped plate 47 can drive the tray 49 and the material receiving box 50 to reciprocate and oscillate. Therefore, under the cooperation of the second sliding pin 46 and the second disc cam 43, The T-shaped plate 47 and the material receiving box 50 can intermittently reciprocate and vibrate forward and backward. When the material receiving box 50 reciprocates and moves forward and backward, the materials can be loaded more evenly. When the intermittent stop occurs, that is, when the second sliding pin 46 is engaged with the arc groove 44, it is the unloading process, which can make the materials more accurately pushed into the material receiving box 50. Through the mutual cooperation of the cylindrical cam 9, the first disc cam 19, and the second disc cam 43, under the cooperation of the first disc cam 19 and the first sliding pin 20, the paddle 25 can move forward first to put the ceramic chip When the grinding table 22 is pushed to the designated position, i.e., the front end of the grinding table 22, the paddle plate 25 stops intermittently, and then the cylindrical cam 9 and the third sliding pin 10 cooperate to enable the pressing plate 14 to move downward to squeeze the grinding belt 6. At this time, the grinding belt 6 contacts the ceramic chip for grinding. At the same time, the second disc cam 43 and the second sliding pin 46 cooperate to enable the material receiving box 50 to reciprocate and oscillate, i.e., it reciprocates and oscillates for one cycle during grinding, so that the material in the material receiving box 50 is loaded more evenly. After the grinding is completed, the material receiving box 50 no longer moves forward. After the cam 19 and the first sliding pin 20 cooperate, the vertical plate 24 and the paddle plate 25 can be driven to move backward to the top and then move forward immediately. When the vertical plate 24 moves backward, the spur rack 35 is engaged with the spur gear and the material receiving box 50 can be driven to move slowly to one side for a distance to change the material receiving position of the material receiving box 50. When the paddle plate 25 moves forward again, the polished ceramic chips can be pushed and unloaded, and the ceramic chips to be polished can be pushed to the designated position for polishing, which can be repeated in a cycle.

[0051] When the present invention is in use, by setting a vertical plate 24 that can move forward and backward, when the vertical plate 24 moves forward, it can push the ceramic chip at the bottom of the storage rack 32, so that the ceramic chip reaches the front end position of the polishing table 22, that is, the specified position; by setting a pressure plate 14 that can move up and down, when the pressure plate 14 moves downward, it can press the polishing belt 6 downward, so that the polishing belt 6 contacts the ceramic chip, and the ceramic chip can be polished when the polishing belt 6 moves; the ceramic chip can be polished automatically throughout the whole process, replacing manual operation, reducing human resource occupation and improving polishing efficiency.
