Description

Technical Field

[0001] The invention belongs to the technical field of grinding wheel manufacturing, and particularly discloses a grinding wheel manufacturing and forming machine with an automatic feeding structure and a manufacturing process. Background Art

[0002] Grinding wheel is an important grinding tool, widely used in many fields such as metal cutting and grinding. Nowadays, grinding wheels are usually manufactured in batches by grinding wheel manufacturing and forming machines. Grinding wheel manufacturing and forming machines use a series of precise process flows to mix various raw materials (such as abrasives, binders, etc.) in a certain ratio, and then press and solidify them to form grinding wheel products with specific shapes and properties. Existing grinding wheel forming machines complete the manufacturing of grinding wheels through the operations of raw material preparation, raw material transportation, injection, molding, curing, demoulding, cooling and inspection.

[0003] The existing grinding wheel forming machine generally uses a spiral feeding device to intermittently transport the mixed raw materials to the weighing device, and then the weighing device injects a certain amount of powder raw materials into the mold in sequence. However, during the intermittent movement of the powder raw materials in the spiral feeder, when the powder raw materials stop moving, due to the gravity of the powder raw materials themselves and the attraction of the powder particles themselves, the powder particles attract each other and aggregate to form small agglomerates. Then, the spiral feeding device transports the small agglomerates to accelerate their aggregation speed, making it easy for agglomerates to occur in the spiral feeding device, causing the auger in the spiral feeder to stop rotating due to the increased rotational resistance, thereby causing blockage in the spiral feeding device, requiring the grinding wheel forming machine to be stopped for unblocking, affecting the continuous production of the grinding wheel, and causing the quality stability of the grinding wheels produced by the grinding wheel forming machine to decline. For this reason, it is necessary to invent a grinding wheel forming machine with an unblocking spiral feeder. Summary of the Invention

[0014] As a preferred embodiment of the present invention, a grinding wheel manufacturing process with an automatic feeding structure, based on the above-mentioned grinding wheel manufacturing and forming machine with an automatic feeding structure, comprises the following steps:

[0015] S1: The mixed powder raw materials are placed into the feed shell of the fixed shell, and then the motor and the stirring mechanism are turned on. The stirring mechanism continuously stirs the powder raw materials in the feed shell of the fixed shell. The output shaft of the motor intermittently drives the connecting sleeve to rotate through the transmission block and the limit block. The connecting sleeve drives the sliding rod and the auger to rotate through the limit column. The auger rotates to transport the powder raw materials to the discharge port of the fixed shell for discharge. The discharged powder raw materials enter the forming mechanism to be processed into a grinding wheel;

[0016] S2: When the powder raw material conveyed in the fixed shell is blocked, the auger cannot rotate, the connecting sleeve rotates and pushes the sliding rod to move through the threaded groove on it, and the sliding rod clears the blockage in the fixed shell through the connecting rod and the rotating block.

Finally, the operator turns off the motor and the stirring mechanism and clears the blockage in the fixed shell.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention drives the auger and the sliding rod to rotate through the connecting sleeve, so that when there is a blockage in the fixed shell, the connecting rod and the rotating block move to clear the blockage, thereby achieving the purpose of quickly clearing the blockage in the fixed shell, reducing the possibility of the molding mechanism being shut down due to blockage of the fixed shell, and ensuring the continuity of the production of grinding wheels by this device.

[0019] 2. The present invention continuously stirs the powder raw materials in the fixed shell feed shell through the continuous operation of the auger in the fixed shell feed shell, thereby avoiding agglomeration of the undelivered powder raw materials and affecting the stability and uniformity of the powder raw materials delivered by the fixed shell.

[0020] 3. The present invention controls the telescopic end of the first hydraulic cylinder in the reset assembly to push the sliding rod to move by contacting and squeezing the extrusion plate and the fixed column, thereby achieving the purpose of clearing the blockage in the fixed shell and resetting the sliding rod at the same time, so that the device can continuously clear the blockage in the fixed shell and extend the continuous working time of the device.

[0021] 4. The present invention drives the sliding plate to move by the telescopic end of the second hydraulic cylinder in the release mechanism, and quickly disconnects the transmission connection between the transmission block and the connecting sleeve when the blockage in the fixed shell cannot be cleared, thereby avoiding overloading of the motor and affecting the service life of the motor.

[0038] Please refer to Figure 8 and Figure 9 As shown, the dredging detection mechanism includes a hydraulic telescopic rod 301, which is fixed to the left side of the fixed shell 4, and a telescopic end of the hydraulic telescopic rod 301 is fixed to a squeeze plate 302, and a squeeze block 303 is slidably connected to the circular plate 11, and a fixed column 305 is slidably connected to the circular plate 11, and the fixed column 305 is squeezed and matched with the squeeze plate 302. A damping is provided on the contact surface between the fixed column 305 and the circular plate 11, so that the fixed column 305 moves only under the action of an external force, and an inclined surface is provided on the left side of the squeeze block 303, and the inclined surface of the squeeze block 303 is squeezed and matched with the fixed column 305, and the connection on the rear side A fixing rod 304 is provided on the connecting rod 12, and the fixing rod 304 is squeezed and matched with the extrusion block 303. Initially, the distance between the fixing rod 304 and the extrusion block 303 is smaller than the moving distance of the fixing rod 304, which is used to trigger the extrusion block 303 before the connecting rod 12 moves to the extreme position. A fixing column 305 is fixedly connected to the left side of the fixed shell 4, and the fixing column 305 is squeezed and matched with the extrusion plate 302 to achieve the purpose of detecting whether the fixed shell 4 is unblocked and whether the auger 5 can rotate. A reset component for making the sliding rod 10 move in the opposite direction is provided on the left side of the fixed shell 4, and hydraulic oil is filled in the hydraulic telescopic rod 301.

[0039] Please refer to Figure 8 and Figure 9As shown, the reset assembly includes a first hydraulic cylinder 401, which is fixed to the left side of the fixed shell 4 through a fixed bent rod. The first hydraulic cylinder 401 is located on the left side of the fixed shell 4. The telescopic end of the first hydraulic cylinder 401 is squeezed and matched with the sliding rod 10 to detect whether the sliding rod 10 moves or pushes it to reset. The first hydraulic cylinder 401 is connected to a liquid guide tube 402, which is connected to the hydraulic telescopic rod 301. A reset bent rod 403 is fixed to the left side of the sliding rod 10. The reset bent rod 403 is provided with a A fixed block is provided, and an inclined plate is provided on the fixed block of the reset bent rod 403. The inclined plate of the fixed block on the reset bent rod 403 is squeezed and matched with the fixed column 305. The guide tube 402 is filled with hydraulic oil. The fixed column 305 and the squeezing plate 302 are in contact and squeezed with each other, and the telescopic end of the first hydraulic cylinder 401 is controlled to push the sliding rod 10 to move and reset, so as to achieve the purpose of clearing the blockage in the fixed shell 4 and resetting the sliding rod 10 at the same time, so that the device can continuously clear the blockage in the fixed shell 4 and extend the continuous working time of the device.

[0040] When using this device for continuous production of grinding wheels, the operator first injects the mixed powder raw materials into the feed shell of the fixed shell 4, and then the operator starts the motor 3 and the stirring mechanism 6 through the control panel. After the stirring mechanism 6 is started, it begins to continuously stir the powder raw materials accumulated in the feed shell of the fixed shell 4 to avoid the powder raw materials in the feed shell of the fixed shell 4 from agglomerating. After the motor 3 is started, the output shaft of the motor 3 drives the transmission block 7 to rotate, and the transmission block 7 drives the connecting sleeve 8 to rotate synchronously through the limit block 9. Since the baffle 202 blocks the limit column 201 at the initial stage, the limit column 201 does not slide in the spiral groove on the inner wall of the connecting sleeve 8. The connecting sleeve 8 drives the auger 5 and the sliding rod 10 to rotate synchronously through the limiting column 201. The auger 5 drives the circular plate 11 to rotate synchronously through the sliding rod 10 and the connecting rod 12. The auger 5 rotates in the fixed shell 4 to convey the powder raw material in the feed shell of the fixed shell 4 to its discharge port for discharge. When the total amount of powder raw material conveyed by the fixed shell 4 reaches the set value, the control panel temporarily turns off the motor 3. At this time, the molding mechanism 1 starts to process the powder raw material, and then the motor 3 is restarted to continue conveying the powder raw material, thereby enabling the auger 5 to achieve the purpose of intermittently conveying the powder raw material. The present device performs continuous production of grinding wheels through the molding mechanism 1.

[0041] The spiral groove of the connecting sleeve 8 drives the sliding rod 10 and the parts connected thereto to move to the left through the limiting post 201, and the limiting post 201 moves in the slide groove of the auger 5, and the sliding rod 10 drives the four connecting rods 12 to move to the left, and the connecting rod 12 slides relative to the auger 5.

[0042] In the process of the four connecting rods 12 moving to the left, the connecting rod 12 drives several rotating blocks 13 thereon to move. During the movement, the rotating block 13 contacts and squeezes the blockage in the fixed shell 4. The spiral strips on the rotating block 13 squeeze the blockage in the fixed shell 4. The rotating block 13 rotates on the corresponding connecting rod 12. As the rotating block 13 rotates, it inserts into the blockage in the fixed shell 4, and gradually breaks the raw material agglomerates at the blockage in the fixed shell 4. Several rotating blocks 13 move synchronously to achieve the effect of simultaneously unblocking a single or multiple blockages in the fixed shell 4, so that the device can quickly unblock when a blockage occurs in the fixed shell 4, avoiding the shutdown of the device due to blockage in the fixed shell 4, which affects the continuity of the production of grinding wheels by this device.

[0043] When the connecting rod 12 moves to the left, the sliding rod 10 pushes the telescopic end of the first hydraulic cylinder 401 to retract, and the hydraulic oil in the hydraulic telescopic rod 301 flows into the first hydraulic cylinder 401 through the guide tube 402. The telescopic end of the hydraulic telescopic rod 301 extends and drives the extrusion plate 302 to move synchronously. When the connecting rod 12 is about to move to the left to the limit, the fixed rod 304 on the rear connecting rod 12 contacts and pushes the extrusion block 303 to move to the left. The inclined surface of the extrusion block 303 squeezes and pushes the fixed column 305 and the parts connected to it to slide downward. When the connecting rod 12 moves to the left to the limit, the limit column 201 is located at the leftmost side of the spiral groove of the connecting sleeve 8. As the connecting sleeve 8 rotates, the limit column 201 tries to drive the sliding rod 10 and the auger 5 to rotate, and detects whether the fixed shell 4 is unblocked. If the blockage in the fixed shell 4 is unblocked, the auger 5 starts to rotate again.

[0044] When the auger 5 starts to rotate again, the rotation of the auger 5 continues to drive the circular plate 11 to rotate through the sliding rod 10 and the connecting rod 12, and the fixed shell 4 continues to perform the above-mentioned powder raw material conveying operation. When the circular plate 11 rotates, it drives the fixed column 305 on it to rotate synchronously. The fixed column 305 contacts the extrusion plate 302 that squeezes the telescopic end of the hydraulic telescopic rod 301 during the rotation of the circular plate 11. The extrusion plate 302 squeezes the telescopic end of the hydraulic telescopic rod 301 to contract, and the hydraulic oil in the guide tube 402 performs the above-mentioned reverse flow. The telescopic end of the first hydraulic cylinder 401 extends and pushes the sliding rod 10 and the parts connected to it to move to the right and reset. The limiting column 201 moves in the opposite direction in the spiral groove of the connecting sleeve 8 and resets. The auger 5 rotates in the opposite direction in the connecting sleeve 8 and resets.

[0045] When the sliding rod 10 is about to reset, the sliding rod 10 drives the reset bent rod 403 to move synchronously, the fixed block inclined plate on the reset bent rod 403 squeezes the fixed column 305, the fixed column 305 moves and resets, and the fixed column 305 squeezes the inclined surface of the fixed rod 304 to reset it, and the fixed column 305 gradually loses contact with the extrusion plate 302. At the same time, the upper limit column 201 of the sliding rod 10 contacts the extrusion baffle 202, and the baffle 202 moves into the connecting sleeve 8 and compresses the connected spring. When the limiting column 201 returns to its initial position in the spiral groove of the connecting sleeve 8, the extrusion plate 302 loses contact with the fixed column 305, and the baffle 202 moves and resets under the elastic force of the connected spring, and the limiting column 201 returns to the limited state, and the fixed shell 4 continues to perform the above-mentioned initial powder raw material conveying operation. When the fixed shell 4 is blocked again, the above-mentioned dredging operation and resetting operation are repeated.

[0046] If the connecting rod 12 drives the rotating block 13 to move but fails to dredge the fixed shell 4, it means that the degree of blockage in the fixed shell 4 is relatively large. The operator turns off the motor 3 and the stirring mechanism 6 through the control panel, and manually dredges the fixed shell 4. The rotating block 13 dredges the fixed shell 4, so that the fixed shell 4 can dredge itself when the degree of internal blockage is not large, effectively extending the continuous working time of the device. The device only stops when the fixed shell 4 is seriously blocked, ensuring the continuous working state of the device.

[0047] After the operator clears the blockage in the fixed shell 4, he manually moves the sliding rod 10 to reset it, and the relevant parts perform the corresponding reset operation mentioned above. Then the operator restarts the motor 3 and the stirring mechanism 6 through the control panel. When the device is completed, all parts return to their initial positions.

[0048] In the above embodiment, the connection relationship between the sliding rod 10 and the limiting column 201 is fixed. However, in embodiment 2, the limiting column 201 slides in a sealed manner in the blind hole of the sliding rod 10 .

[0049] Example 2: In order to ensure the safe operation of the motor 3 and avoid serious overload, the transmission block 7 and the connecting sleeve 8 in this device are transmitted through the limit block 9, so that the transmission is disconnected when the motor 3 is overloaded, thereby ensuring the safety of the motor 3 itself, improving the service life of the motor 3, and improving the efficiency of the grinding wheel forming machine.

[0050] Based on Example 1, please refer to Figure 10 and Figure 11 The lifting mechanism 502 is a kind of lifting mechanism that is used for lifting the lifting block 7 and the lifting block 8. As shown in the figure, it also includes a releasing mechanism, which is arranged in the blind hole of the connecting sleeve 8, and the releasing mechanism is used to release the transmission between the transmission block 7 and the connecting sleeve 8. The releasing mechanism includes a second hydraulic cylinder 501, and the second hydraulic cylinder 501 is embedded in the blind hole of the connecting sleeve 8. The telescopic end of the second hydraulic cylinder 501 is fixedly connected with a sliding plate 502, and the sliding plate 502 is slidably connected to the connecting sleeve 8. The sliding plate 502 is squeezed and matched with the limit block 9. The right end of the sliding rod 10 is provided with a cavity, and the limit column 201 slides in the cavity of the sliding rod 10. A spring is fixed between the limit column 201 and the sliding rod 10, and the right end of the sliding rod 10 is slidably connected to the limit pin 504, which is limitedly matched with the limit pin 504 and the limit pin 504. The resistance of the limit pin 504 to the limit column 201 is greater than the resistance of the baffle 202 to the limit column 201, which is used to make the connecting sleeve 8 stably drive the auger 5 to rotate, and the limit When the auger 5 is obstructed from rotating, the baffle 202 moves first, and then the limit pin 504 is pressed and moved, releasing the limit column 201 from the position, so as to detect that the fixed shell 4 has not been cleared by the rotating block 13. A spring is fixedly connected between the limit pin 504 and the sliding rod 10, and the cavity of the sliding rod 10 is connected to the guide tube 503, which is connected to the second hydraulic cylinder 501. The cavity of the sliding rod 10 and the guide tube 503 are both filled with hydraulic oil. The limit pin 504 blocks the movement of the limit column 201, so that the sliding rod 10 moves and drives the rotating block 13 to clear the blockage in the fixed shell 4. Only when the blockage in the fixed shell 4 is not cleared, the transmission between the transmission block 7 and the connecting sleeve 8 stops, making the motor 3 unloaded, avoiding long-term overload of the motor 3 and reducing the service life of the motor 3.

[0051] When a blockage occurs in the fixed shell 4, the auger 5 stops rotating, and the connecting rod 12 drives the rotating block 13 thereon to move to dredge the blockage in the fixed shell 4. If the rotating block 13 fails to dredge the blockage in the fixed shell 4, when the force of the spiral groove of the connecting sleeve 8 squeezing the limit column 201 is greater than the force of the limit pin 504 obstructing the limit column 201, it means that the rotating block 13 on the connecting rod 12 cannot continue to move to dredge the blockage in the fixed shell 4, or the limit column 201 moves to the far left in the spiral groove of the connecting sleeve 8. Then, as the connecting sleeve 8 continues to rotate, the spiral groove of the connecting sleeve 8 squeezes the limit column 201, the limit column 201 moves downward and compresses the connected spring, the limit column 201 squeezes the limit pin 504, the limit pin 504 moves to the right and compresses the connected spring, and the limit column 201 moves into the blind hole of the sliding rod 10.

[0052] When the limit column 201 moves into the blind hole of the sliding rod 10, the hydraulic oil in the blind hole of the sliding rod 10 flows into the second hydraulic cylinder 501 through the guide pipe 503. The telescopic end of the second hydraulic cylinder 501 extends and pushes the limit block 9 out of the blind hole of the connecting sleeve 8 through the sliding plate 502. The limit block 9 moves to the right and enters the transmission block 7 and compresses the connected spring. The transmission block 7 and the connecting sleeve 8 rotate with each other and lose the transmission effect. The motor 3 idles to avoid overload of the motor 3, which affects the service life of the motor 3 and ensures that the operator has enough time to react. When the motor 3 idles, the operator turns off the motor 3 and the stirring mechanism 6 through the control panel, and the device stops working. The operator repeats the above-mentioned solid The fixed shell 4 is manually unblocked, and the operator manually rotates the connecting sleeve 8 at the same time. When the limit column 201 is aligned with the spiral groove in the connecting sleeve 8, the limit column 201 moves and resets under the elastic force of the spring, and the hydraulic oil in the guide tube 503 flows in the opposite direction. The telescopic end of the second hydraulic cylinder 501 contracts and drives the sliding plate 502 to reset. As the connecting sleeve 8 rotates, when the limit block 9 is aligned with the blind hole of the connecting sleeve 8, the limit block 9 moves and is inserted into the blind hole of the connecting sleeve 8 under the elastic force of the connected spring, and all parts return to their initial positions. After that, the device continues to repeat the above-mentioned feeding operation until the device completes the production of all grinding wheels, shuts down the device, and all parts in the device return to their initial positions.

[0053] Example 3: Based on Example 2, please refer to Figures 1-11 As shown, a grinding wheel manufacturing process with an automatic feeding structure is applied to the above-mentioned grinding wheel manufacturing and forming machine with an automatic feeding structure, comprising the following steps:

[0054] S1: The mixed powder raw materials are placed into the feed shell of the fixed shell 4, and then the motor 3 and the stirring mechanism 6 are turned on. The stirring mechanism 6 continuously stirs the powder raw materials in the feed shell of the fixed shell 4. The output shaft of the motor 3 intermittently drives the connecting sleeve 8 to rotate through the transmission block 7 and the limit block 9. The connecting sleeve 8 drives the sliding rod 10 and the auger 5 to rotate through the limit column 201. The auger 5 rotates to transport the powder raw materials to the discharge port of the fixed shell 4 for discharge. The discharged powder raw materials enter the forming mechanism 1 to be processed into a grinding wheel;

[0055] S2: When the powder raw material conveyed in the fixed shell 4 is blocked, the auger 5 cannot rotate, the connecting sleeve 8 rotates and pushes the sliding rod 10 to move through the threaded groove on it, and the sliding rod 10 clears the blockage in the fixed shell 4 through the connecting rod 12 and the rotating block 13. If the blockage in the fixed shell 4 is cleared, the auger 5 continues to rotate with the sliding rod 10 and the connecting sleeve 8, and the extrusion plate 302 at the telescopic end of the hydraulic telescopic rod 301 is squeezed by the fixed column 305, so that the telescopic end of the first hydraulic cylinder 401 pushes the sliding rod 10 to reset;

[0056] S3: If the blockage in the fixed shell 4 is not cleared, the limiting column 201 moves to the limit in the spiral groove of the connecting sleeve 8, and then rotates with the connecting sleeve 8, and the limiting column 201 moves, so that the telescopic end of the second hydraulic cylinder 501 pushes the limiting block 9 through the sliding plate 502, and the transmission between the transmission block 7 and the connecting sleeve 8 is released, and the motor 3 idles. Finally, the operator turns off the motor 3 and the stirring mechanism 6 and clears the blockage in the fixed shell 4.
