Detailed Implementation

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0013] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8This utility model provides a technical solution: a blanking mechanism for a grinding and polishing machine, comprising: a base 1, a grinding barrel 13 extending to the upper end of the base 1 installed on the top of the inside of the base 1, the grinding barrel 13 being used to collect wastewater generated during grinding, and a grinding wheel 11 located directly below the clamp 21 being movably disposed inside the grinding barrel 13, the grinding wheel 11 being used for grinding operations, and a fixed part of a first driving device 14, whose movable part passes through the handle of the grinding barrel 13 and is connected to the grinding wheel 11, being installed inside the base 1, the first driving device 14 driving the grinding wheel 11 to rotate, and an annular cover 12 with a conical cross-section arranged with a wider bottom and a narrower top and located outside the grinding wheel 11, being installed on the upper end of the base 1, the annular cover 12 being connected to the grinding barrel 13, the annular cover 12 being used to block splashed waste chips and other materials; A support column 22 extending into the top seat 2 is set on the upper rear side of the base 1. The support column 22 supports the top seat 2 and rotatably connects the top seat 2 to the upper end of the support column 22. The top seat 2 provides installation space for components such as the second drive device 23. The second drive device 23, whose movable part is connected to the support column 22, is then installed on the inner rear side of the top seat 2. The second drive device 23 drives the top seat 2 to rotate. A third drive device 24, located in front of the second drive device 23 and whose movable part extends out of the lower side of the top seat 2, is set on the inner front side of the top seat 2. The third drive device 24 drives the clamp 21 to move up and down and rotates the clamp 21. The clamp 21 is then installed on the lower end of the movable part of the third drive device 24 to clamp the blank.

[0014] The mounting frame 41 is set on the side of the base 1. The mounting frame 41 provides a mounting carrier for the outer shell 4. The outer shell 4, located outside the base 1, is mounted on the front end of the mounting frame 41. The outer shell 4 provides a mounting carrier for components such as the storage cylinder 3. The storage cylinder 3, which penetrates the outer shell 4, is set on the upper end of the outer shell 4. The storage cylinder 3 is used for temporary storage of blanks. The fixed part of the telescopic device is installed on the right end of the outer shell 4. The telescopic device drives the feeding plate 6 to move left and right. The telescopic device can be an electric push rod 5. The horizontal part of the feeding plate 6, which has an L-shaped cross-section, is attached to the lower end of the storage cylinder 3. The movable part of the telescopic device is connected to the vertical part of the feeding plate 6. The feeding plate 6 is used for feeding blanks. A positioning groove 61 is formed at the lower end of the storage cylinder 3 by a downward recess on the upper surface of the feeding plate 6. The positioning groove 61 is used for positioning and placing the blank. The second telescopic rod 51 located outside the telescopic device is set on the right end of the outer shell 4, and the movable part of the second telescopic rod 51 is connected to the vertical part of the feeding plate 6. The second telescopic rod 51 guides the movement of the feeding plate 6. A tapered tube 31 with a wide upper part and a narrow lower part is connected and set on the upper end of the storage cylinder 3. The tapered tube 31 facilitates the placement of the blank into the storage cylinder 3.

[0015] In use, multiple blanks are first placed into the storage cylinder 3 in sequence to temporarily store multiple blanks in the storage cylinder 3. At this time, the blank at the bottom enters the positioning groove 61. Then, the electric push rod 5 is started to drive the feeding plate 6 to move to the left, thereby causing the blank in the positioning groove 61 to move to the left. At this time, the horizontal part of the feeding plate 6 blocks the lower opening of the storage cylinder 3, thereby preventing the blank in the storage cylinder 3 from moving down. Then, the blank is moved to the bottom of the clamp 21, and the third drive device 24 is started to drive the clamp 21 to move down, thereby clamping the blank between the clamp 21 and the blank. Then, the clamped blank is moved up by the third drive device 24 and separated from the positioning groove 61. Then, the electric push rod 5 is used to move the feeding plate 6 to the right and return to its original position. Then, the blank at the bottom of the storage cylinder 3 moves down and enters the positioning groove 61, realizing mechanical automatic blank loading operation, effectively reducing the probability of blank installation tilting due to manual feeding factors, effectively reducing labor intensity, improving work efficiency, and effectively ensuring grinding effect and quality. Then, the second drive device 23 is activated, which drives the top seat 2 to rotate, thereby moving the clamped blank to the initial position. At this time, the blank and the grinding wheel 11 are eccentric. Then, the third drive device 24 is activated, which drives the clamp 21 and the clamped blank to move down, thereby making the blank and the grinding wheel 11 come into contact. Then, the clamped blank is driven to rotate. At the same time, the first drive device 14 is activated, which drives the grinding wheel 11 to rotate. At this time, the rotation direction of the grinding wheel 11 is relative to the rotation direction of the blank, thereby realizing the grinding and polishing operation on the blank.

[0016] Example 2, as Figures 5-7 As shown, multiple limiting plates 32 extending into the storage cylinder 3 are evenly and movably arranged on the outer end of the storage cylinder 3. The limiting plates 32 block the blanks entering the storage cylinder 3. A chamfer is provided on the inner edge of the upper side of the limiting plate 32. The chamfer facilitates the blanks to continue to move down. Multiple movable plates 33 are respectively arranged on the outer ends of the multiple limiting plates 32. The movable plates 33 provide a mounting carrier for components such as the magnetic block 34. Multiple magnetic blocks 34 located inside the electromagnet 7 are respectively installed on the outer ends of multiple movable plates 33. The electromagnet 7 is installed on the inner wall of the outer casing 4, and the electromagnet 7 and magnetic blocks 34 are arranged to repel each other. The electromagnet 7 and magnetic blocks 34 work together to make the movable plates 33 move inward. Multiple elastic elements 35 located outside the limiting plate 32 are installed on the inner ends of the movable plates 33, and the other ends of the multiple elastic elements 35 are connected to the outer end of the storage cylinder 3. The multiple elastic elements 35 work together to make the movable plates 33 return to their original position. The elastic elements 35 can be springs. Multiple first telescopic rods 36 located inside the multiple elastic elements 35 are equidistantly arranged between the inner end of the movable plates 33 and the outer end of the storage cylinder 3. The movement of the movable plates 33 is guided by the first telescopic rods 36.

[0017] Before use, the circuit of electromagnet 7 is turned on. Because electromagnet 7 and magnetic block 34 are arranged to repel each other, a repulsive force is generated between electromagnet 7 and magnetic block 34. Under the action of the repulsive force, multiple magnetic blocks 34 move inward, which in turn causes multiple movable plates 33 to move inward, thereby compressing the elastic element 35, causing the elastic element 35 to generate elastic force, and causing multiple limiting plates 32 to move inward and enter the storage cylinder 3. Then, blanks are placed into storage cylinder 3. The blanks first come into contact with the uppermost limiting plate 32. At this time, the limiting plate 32 will restrict the blanks, causing them to stop. Then, the blank placement operation continues. Under the weight of multiple blanks and with the assistance of chamfering, the limiting plate 32 moves outward, causing the blanks to continue to move downward. The same steps are repeated to temporarily place multiple blanks into storage cylinder 3, realizing a multi-stage downward movement operation of the blanks placed in storage cylinder 3. This effectively reduces the probability of blank damage caused by the placement operation and effectively ensures the polishing effect and quality. When the storage cylinder 3 is full of blanks, the circuit of the electromagnet 7 is disconnected, thereby eliminating the repulsive force between the electromagnet 7 and the magnetic block 34. Under the action of the elastic force of the elastic element 35, the movable plate 33 moves outward, which in turn causes the limiting plate 32 to move outward and return to its original position. This effectively avoids obstructing the downward movement of the blanks in the storage cylinder 3 during the blank loading process, and effectively ensures that the blank loading operation can be carried out normally.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
