Description

Technical Field

[0001] This invention relates to the field of grinding wheel manufacturing technology, and more specifically to a feeding device for a grinding wheel forming machine. Background Technology

[0002] A feeding device for a grinding wheel forming machine is a device that supplies abrasive to the grinding wheel pressing and forming machine. Existing feeding devices for grinding wheel forming machines include a feeding cylinder; abrasive is placed into the feeding cylinder during use. However, it has been found that because the grinding wheels contain other additives, they are prone to clumping, causing blockage at the discharge end of the feeding cylinder. This affects the normal supply of abrasive, reduces the pressing efficiency of the grinding wheel, and limits its application. Clumped abrasive fed into the forming mold results in uneven abrasive distribution, leading to insufficient subsequent bonding reaction and the production of defective products. Summary of the Invention

[0003] In view of the above, the present invention provides a feeding device for a grinding wheel forming machine, which can crush the agglomerated abrasive material in advance during the feeding process, thereby improving the grinding wheel production efficiency and grinding wheel quality.

[0004] The technical solution of the present invention:

[0005] This invention provides a feeding device for a grinding wheel forming machine, including a vibration mechanism, a feeding cylinder, a crushing and grinding mechanism, and a quantitative feeding mechanism. The feeding cylinder is installed on the vibration mechanism to vibrate the feeding cylinder and screen out uniformly sized sand. The crushing and grinding mechanism includes a support, a crushing motor, a main wheel body, and a crushing wheel. The support is installed on the top of the feeding cylinder, and the crushing motor is installed on the support. The output shaft of the crushing motor is eccentrically connected to the main wheel body and is coaxially arranged with the feeding cylinder. The main wheel body is located inside the feeding cylinder, and the crushing wheel is rotatably installed on the outer periphery of the main wheel body. A crushing gap is formed between the crushing wheel and the inner wall of the feeding cylinder to crush the agglomerated sand into uniform particles. The feeding cylinder is equipped with a screen for filtering the sand, and the quantitative feeding mechanism is located on one side below the feeding cylinder to receive the sand filtered by the screen and quantitatively feed it into the forming mold of the grinding wheel forming machine.

[0006] Furthermore, the crushing mechanism includes a first coupling, an eccentric shaft is fixed on the main wheel body, and the output shaft of the crushing motor is connected to the eccentric shaft through the first coupling, thereby realizing the eccentric transmission connection between the output shaft of the crushing motor and the main wheel body.

[0007] or,

[0008] The output shaft of the crushing motor is fixedly connected to the central axis of the main wheel body through a transmission rod. The output shaft of the crushing motor is offset from the central axis of the main wheel body, thereby realizing the eccentric transmission connection between the output shaft of the crushing motor and the main wheel body.

[0009] Furthermore, the feeding cylinder includes a bottom wall and a peripheral wall. The bottom wall is a conical wall with a high center and a low outer perimeter. The peripheral wall surrounds the outer perimeter edge of the conical wall to form a cylindrical container with the opening facing upward.

[0010] Furthermore, the screen is located at the bottom of the peripheral wall, and the feeding cylinder also includes a feeding trough. One end of the feeding trough is connected to the peripheral wall and communicates with the screen, and the other end of the feeding trough extends above the quantitative feeding mechanism.

[0011] Furthermore, the bottom surface of the main wheel body is formed with a conical surface that is adapted to the conical wall, and the tip of the conical surface is located on the axis of the conical wall.

[0012] Furthermore, the height of the compaction wheel is less than the height of the main wheel body, so as to form a material storage channel below the compaction gap. The main wheel body has a scraper located in the material storage channel to scrape the sand collected in the material storage channel to the screen for output.

[0013] Furthermore, the quantitative dispensing mechanism includes a receiving container, a leveling component, a leveling motor, a discharging assembly, and a hopper. The receiving container is used to receive sand from the feeding cylinder. The receiving container is provided with a fixed material trough of a specified volume. The discharging assembly is installed on the receiving container and corresponds to the fixed material trough to close the fixed material trough to store a fixed quantity of sand or open the fixed material trough to release a fixed quantity of sand. The leveling component is rotatably connected to the receiving container to scrape sand into the fixed material trough. The leveling motor is mounted on the receiving container and is driven by the rotating shaft of the leveling component to drive the leveling component to rotate and scrape the sand into the fixed material trough. The hopper is installed at the bottom of the receiving container and below the fixed material trough to guide the sand into the forming mold of the grinding wheel forming machine.

[0014] Furthermore, the quantitative dispensing mechanism also includes a second coupling, through which the output shaft of the leveling motor and the rotating shaft of the leveling component are connected. The quantitative dispensing mechanism also includes a sand sensor and a leveling component sensor. The sand sensor is mounted on the receiving container and located at the material drop position of the feeding cylinder to detect whether the amount of sand is sufficient to fill the fixed material trough. The leveling component sensor is installed on the feeding cylinder, and a sensing component that cooperates with the leveling component sensor is installed on the second coupling. When the leveling component sensor detects the sensing component, it controls the leveling motor to stop, so that the leveling component stops at the material drop position near the feeding cylinder, allowing the sand to accumulate to a certain height along the leveling component for the sand sensor to detect. When the sand sensor detects that the amount of sand is sufficient to fill the fixed material trough, it controls the leveling motor to start, so that the leveling component rotates one revolution and stops, thereby filling the fixed material trough with sand.

[0015] Furthermore, the unloading assembly includes an unloading plate and an unloading drive. The unloading plate is hinged to the bottom of the receiving container and corresponds to the position of the fixed material trough. The unloading drive is installed at the bottom of the receiving container to drive the unloading plate to rotate, thereby opening or closing the fixed material trough.

[0016] Furthermore, the quantitative dispensing mechanism also includes an adjustment component for adjusting the volume of the material trough. The adjustment component includes an adjustment plate, a fixed base, and an adjustment rod. One end of the material trough extends outward through the peripheral wall of the receiving container. The adjustment plate is slidably installed inside the material trough. The fixed base is fixed to the receiving container and has a screw hole for screwing the adjustment rod. The adjustment rod passes through the fixed base and is rotatably connected to the adjustment plate.

[0017] The beneficial effects of this invention are:

[0018] Compared with the prior art, the feeding device for the grinding wheel forming machine of the present invention, through the combination of a vibration mechanism, a feeding cylinder, a crushing and grinding mechanism, and a quantitative feeding mechanism, and the crushing and grinding mechanism, through the combination of a support, a crushing motor, a main wheel body, and a grinding wheel, drives the main wheel body to rotate. Since the output shaft of the crushing motor is eccentrically connected to the main wheel body, and the output shaft of the crushing motor is coaxially arranged with the feeding cylinder, the main wheel body and the grinding wheel rotate around the output shaft of the crushing motor inside the feeding cylinder, while the grinding wheel rotates around the main wheel body. As the grinding wheel rotates, the compaction wheel moves in a circular motion close to the inner wall of the feeding cylinder. This rotation around the main wheel smoothly draws clumps of sand into the compaction gap while reducing resistance. During this circular motion, the compaction wheel gradually gathers the clumps of sand into the compaction gap. Through the interaction between the compaction wheel and the inner wall of the feeding cylinder, the clumps of sand are crushed into uniform particles. These uniform particles then pass through a screen into the quantitative feeding mechanism for quantitative dispensing. This process ensures comprehensive, thorough, and rapid crushing of the clumps of sand in the feeding cylinder, maximizing sand utilization. The rotating compaction wheel also agitates the sand in the feeding cylinder, improving the uniformity of sand distribution and ensuring smooth discharge from the screen, thus enhancing both the production efficiency and quality of the grinding wheel.

[0028] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] Please see Figures 1 to 4 This invention provides a feeding device for a grinding wheel forming machine, including a vibration mechanism 1, a feeding cylinder 2, a crushing and grinding mechanism 3, and a quantitative feeding mechanism 4. The feeding cylinder 2 is mounted on the vibration mechanism 1 to vibrate the feeding cylinder 2, thereby screening out uniformly sized sand particles. The crushing and grinding mechanism 3 includes a support 31, a crushing motor 32, a main wheel body 33, and a crushing wheel 34. The support 31 is mounted on the top of the feeding cylinder 2, and the crushing motor 32 is mounted on the support 31. The output shaft of the crushing motor 32 is eccentrically connected to the main wheel body 33, and the output shaft of the crushing motor 32 is coaxially arranged with the feeding cylinder 2. The main wheel body 33 is located inside the feeding cylinder 2, and the crushing wheel 34 is rotatably mounted on the outer periphery of the main wheel body 33. A crushing gap 30 is formed between the crushing wheel 34 and the inner wall of the feeding cylinder 2 to crush and grind agglomerated sand particles into uniform particles. The feeding cylinder 2 is equipped with a screen 20 for filtering sand. The quantitative feeding mechanism 4 is located on one side of the feeding cylinder 2 to receive the sand filtered by the screen 20 and quantitatively feed it into the forming mold of the grinding wheel forming machine.

[0030] The feeding device for the grinding wheel forming machine of the present invention is achieved by a combination of a vibration mechanism 1, a feeding cylinder 2, a crushing and grinding mechanism 3, and a quantitative feeding mechanism 4. The crushing and grinding mechanism 3 is configured by a support 31, a crushing motor 32, a main wheel body 33, and a grinding wheel 34. The crushing motor 32 drives the main wheel body 33 to rotate. Since the output shaft of the crushing motor 32 is eccentrically connected to the main wheel body 33 and the output shaft of the crushing motor 32 is coaxially arranged with the feeding cylinder 2, the main wheel body 33 and the grinding wheel 34 rotate around the output shaft of the crushing motor 32 within the feeding cylinder 2. Simultaneously, the grinding wheel 34... Rotating around the main wheel body 33, the compaction wheel 34 moves in a circular motion close to the inner wall of the feeding cylinder 2. This rotation of the compaction wheel 34 around the main wheel body 33 smoothly draws agglomerated sand into the compaction gap 30 while reducing motion resistance. During its circular motion, the compaction wheel 34 gradually gathers the agglomerated sand into the compaction gap 30. Through the interaction between the compaction wheel 34 and the inner wall of the feeding cylinder 2, the agglomerated sand is crushed into uniform particles. These uniform particles then pass through the screen 20 and are quantitatively fed into the metering mechanism 4. This process facilitates comprehensive, thorough, and rapid crushing of the agglomerated sand in the feeding cylinder 2, ensuring full utilization of the sand. The rotating compaction wheel 34 also agitates the sand in the feeding cylinder 2, improving the uniformity of sand distribution and ensuring smooth discharge from the screen 20, thus enhancing the production efficiency and quality of the grinding wheel.

[0031] In this embodiment, the crushing mechanism 3 includes a first coupling 35, an eccentric shaft 36 fixed on the main wheel body 33, and the output shaft of the crushing motor 32 is connected to the eccentric shaft 36 via the first coupling 35, thereby achieving an eccentric transmission connection between the output shaft of the crushing motor 32 and the main wheel body 33. This structure is simple, easy to assemble, and provides stable and reliable transmission, making it better suited for crushing agglomerated sand. In other embodiments, the output shaft of the crushing motor 32 can also be fixedly connected to the central axis of the main wheel body 33 via a transmission rod, with the output shaft of the crushing motor 32 offset from the central axis of the main wheel body 33, thus achieving an eccentric transmission connection between the output shaft of the crushing motor 32 and the main wheel body 33. This allows for smaller sizes of the main wheel body 33 and the crushing wheel 34, with one end of the transmission rod fixed to the central axis of the main wheel body 33 and the other end extending to the outer periphery of the crushing wheel 34 and fixedly connected to the output shaft of the crushing motor 32.

[0032] In this embodiment, there is a rotational gap between the compaction wheel 34 and the main wheel body 33, so that the compaction wheel 34 can be rotatably fitted onto the outer periphery of the main wheel body 33. In other embodiments, a bearing can be installed between the compaction wheel 34 and the main wheel body 33 to better achieve the rotatable connection of the compaction wheel 34 to the main wheel body 33.

[0033] Please see Figure 5In this embodiment, the feeding cylinder 2 includes a bottom wall 21 and a peripheral wall 22. The bottom wall 21 is a conical wall, with a higher center and a lower outer perimeter. The peripheral wall 22 surrounds the outer edge of the conical wall, forming an upward-facing cylindrical container. A screen 20 is located at the bottom of the peripheral wall 22. This facilitates the rapid convergence of sand towards the screen 20 and ensures smooth flow of sand. The feeding cylinder 2 also includes a discharge trough 23. One end of the discharge trough 23 is connected to the peripheral wall 22 and communicates with the screen 20, while the other end extends above the quantitative dispensing mechanism 4. Please refer to [link to relevant documentation]. Figure 4 and Figure 5 Preferably, the bottom surface of the main wheel 33 has a conical surface 331 adapted to the conical wall, and the tip of the conical surface 331 is located on the axis of the conical wall. This allows the conical surface 331 to rotate close to the surface of the conical wall, pushing the sand collected within the conical wall to the screen 20 for output, which is beneficial for the rapid and smooth transport of sand. Preferably, the height of the compaction wheel 34 is less than the height of the main wheel 33, forming a storage channel 37 below the compaction gap 30. The main wheel 33 has a scraper 38 located within the storage channel 37, below the compaction wheel 34 and close to the inner wall of the feed cylinder 2, to scrape the sand collected in the storage channel 37 to the screen 20 for output. Thus, the sand collected in the storage channel 37 is scraped by the scraper 38, increasing the amount of sand scraped and further improving the output efficiency of the sand. The sand in the feeding cylinder 2 is separated into two layers under vibration. The lower layer is uniformly sized sand, which gathers in the storage channel 37. The upper layer is lumpy sand, which gradually gathers in the crushing gap 30. The lumpy sand is crushed into uniformly sized sand in the crushing gap 30 and then falls into the storage channel 37. It is then scraped by the scraper 38 to the screen 20 for output. In this way, the stratification of sand is fully utilized to classify, crush, and scrape the sand, improving the crushing efficiency of lumpy sand and the output efficiency of uniformly sized sand.

[0034] Please see Figure 1 and Figure 6In this embodiment, the quantitative dispensing mechanism 4 includes a receiving container 41, a leveling component 42, a leveling motor 43, a discharging assembly 44, and a feeding hopper 45. The receiving container 41 receives sand from the feeding cylinder 2. A fixed-volume trough 40 with a specified volume is provided inside the receiving container 41; two fixed-volume troughs 40 can be arranged for simultaneous feeding. The discharging assembly 44 is installed on the receiving container 41 and corresponds to the fixed-volume trough 40 to close the fixed-volume trough 40 to store a fixed quantity of sand or to open the fixed-volume trough 40 to release a fixed quantity of sand. The leveling component 42 is rotatably connected inside the receiving container 41 to scrape sand into the fixed-volume trough 40. The leveling motor 43 is mounted on the receiving container 41 and is drively connected to the rotating shaft of the leveling component 42 to drive the leveling component 42 to rotate and scrape sand into the fixed-volume trough 40. The feeding hopper 45 is installed at the bottom of the receiving container 41 and below the fixed material trough 40 to guide the abrasive material into the forming mold of the grinding wheel forming machine. By setting a fixed material trough 40 with a specified volume, the amount of abrasive material required for producing grinding wheels can be controlled more precisely, avoiding the defects of inaccurate measurement caused by moisture in the abrasive material when using the weight feeding method.

[0035] In this embodiment, the quantitative dispensing mechanism 4 further includes a second coupling 46, through which the output shaft of the leveling motor 43 and the rotation shaft of the leveling component 42 are connected. The quantitative dispensing mechanism 4 also includes a sand sensor 47 and a leveling component sensor 48. The sand sensor 47 is mounted on the receiving container 41 and located at the material drop position of the feeding cylinder 2 to detect whether the amount of sand is sufficient to fill the fixed material trough 40. The leveling component sensor 48 is mounted on the feeding cylinder 2, and a sensing element 49 that cooperates with the leveling component sensor 48 is mounted on the second coupling 46. When the leveling component sensor 48 senses the sensing element 49, it controls the leveling motor 43 to stop, so that the leveling component 42 stops at the material drop position near the feeding cylinder 2, allowing the sand to accumulate to a certain height along the leveling component 42 for the sand sensor 47 to sense. When the sand sensor 47 detects that there is enough sand to fill the fixed material trough 40, it controls the leveling motor 43 to start, causing the leveling component 42 to rotate one revolution and stop, thereby filling the fixed material trough 40 with sand. In this way, it is ensured that the fixed material trough 40 is filled with sand with one revolution of the leveling component 42. By controlling the leveling component 42 to rotate intermittently to fill the fixed material trough 40 with sand, unnecessary movements are reduced, energy consumption is reduced, and the efficiency of filling the fixed material trough 40 with sand is improved.

[0036] In this embodiment, the unloading assembly 44 includes an unloading plate 441 and an unloading drive 442. The unloading plate 441 is hinged to the bottom of the receiving container 41 and corresponds to the position of the fixed material slot 40. The unloading drive 442 is installed at the bottom of the receiving container 41 to drive the unloading plate 441 to rotate, thereby opening or closing the fixed material slot 40. The unloading drive 442 is preferably a cylinder.

[0037] In this embodiment, the quantitative dispensing mechanism 4 further includes an adjusting component 400 for adjusting the volume of the material trough 40. The adjusting component 400 includes an adjusting plate 401, a fixed base 402, and an adjusting rod 403. One end of the material trough 40 extends outward through the peripheral wall of the receiving container 41, and the adjusting plate 401 is slidably installed within the material trough 40. The fixed base 402 is fixed to the receiving container 41 and has a screw hole for screwing the adjusting rod 403. The adjusting rod 403 passes through the fixed base 402 and is rotatably connected to the adjusting plate 401. By rotating the adjusting rod 403, the adjusting plate 401 slides along the material trough 40, adjusting the volume of the material trough 40. In this way, the required amount of abrasive can be adjusted according to different grinding wheel specifications, improving the versatility and flexibility of the equipment.

[0038] Please see Figure 1 In this embodiment, the vibration mechanism 1 includes a base 11, an elastic element 12, and a vibration motor 13. The vibration motor 13 is mounted on the base 11 via the elastic element 12, and the feeding cylinder 2 is mounted on the vibrating end of the vibration motor 13 to vibrate the feeding cylinder 2.

[0039] In summary, the feeding device for the grinding wheel forming machine of the present invention, through the cooperation of a vibration mechanism 1, a feeding cylinder 2, a crushing and grinding mechanism 3, and a quantitative feeding mechanism 4, and the crushing and grinding mechanism 3 through the cooperation of a support 31, a crushing motor 32, a main wheel body 33, and a grinding wheel 34, drives the main wheel body 33 to rotate. Since the output shaft of the crushing motor 32 is eccentrically connected to the main wheel body 33, and the output shaft of the crushing motor 32 is coaxially arranged with the feeding cylinder 2, the main wheel body 33 and the grinding wheel 34 rotate around the output shaft of the crushing motor 32 within the feeding cylinder 2, while the grinding wheel 34 rotates simultaneously. Rotating around the main wheel 33, the compaction wheel 34 moves in a circular motion close to the inner wall of the feeding cylinder 2. This rotation of the compaction wheel 34 around the main wheel 33 smoothly draws agglomerated sand into the compaction gap 30 while reducing resistance. During its circular motion, the compaction wheel 34 gradually gathers the agglomerated sand into the compaction gap 30. Through the interaction between the compaction wheel 34 and the inner wall of the feeding cylinder 2, the agglomerated sand is crushed into uniform particles. These uniform particles then pass through the screen 20 and are quantitatively fed into the metering mechanism 4. This process facilitates comprehensive, thorough, and rapid crushing of the agglomerated sand in the feeding cylinder 2, ensuring full utilization of the sand. The rotating compaction wheel 34 also stirs the sand in the feeding cylinder 2, improving the uniformity of sand distribution and ensuring smooth discharge from the screen 20, thus enhancing the production efficiency and quality of the grinding wheel.
