Referring to fig. 1, in some embodiments of the present invention, the present invention provides a scraping device for a grinding wheel sand layer, which includes a frame 10, a lifting assembly 20, a fixing assembly 30 and a scraping plate 40. The lifting assembly 20 is disposed on the frame 10 and connected to the fixing assembly 30, so that the fixing assembly 30 can be driven by the lifting assembly 20 to move up and down. The scraper 40 is mounted on the fixing assembly 30, so that the scraper 40 can be driven by the lifting assembly 20 to move up and down. The scraping device for the grinding wheel sand material layer further comprises a die 50, wherein the die 50 is positioned below the scraper 40, and the die 50 can rotate in the horizontal direction.

Scraper 40 is located mould 50 top, because fixed subassembly 30 is the oscilaltion removal under the drive of lifting unit 20, because mould 50 can the level rotate again, so scraper 40 is under lifting unit 20's drive, stretch into in mould 50, mould 50 level rotate again, scraper 40 can shakeout the sand material layer, so that the sand material evenly distributed in mould 50, thereby make the emery wheel quality of suppressing qualified, and simultaneously, an automatic emery wheel sand material layer scraping device can improve the production efficiency of emery wheel, save labour cost.

Referring to fig. 1 and 2, in some embodiments of the present invention, a plurality of circular holes 41 are formed on the scraper 40, and the circular holes 41 are uniformly arranged in parallel at the lower edge of the scraper 40. When the mold 50 starts to rotate, the scraper 40 is located in the mold ring 51, and rotates relative to the mold 50 with the rotation center of the mold 50 as the rotation center, so that the sand layer (not shown) in the mold 50 can be flattened. However, it should be noted that the sand particles in the sand layer are different in size, and as is well known, when the sand particles with different masses move along with the mold 50 in a circular manner, the linear velocities of the sand particles with different masses are also different, so that the centrifugal forces applied to the particles are also different, and finally, the centrifugal force applied to the sand particles with larger masses is larger, so that the sand particles with larger masses are more and more far away from the center of the mold 50. It will be appreciated that this will eventually lead to an uneven distribution of the sand material of the grinding wheel, thereby degrading the quality of the grinding wheel. Therefore, the lower edge of the scraper 40 is provided with a plurality of round holes 41, and the round holes 41 allow the sand particles with large mass to pass through, so as to prevent the sand particles from moving to the outside of the mold 50 due to the fact that some sand particles cannot be flattened and the quality of the grinding wheel is affected.

The number of the circular holes 41 may be 15, 18, or 10, but it should be noted that the number of the circular holes 41 is not specifically limited in this embodiment, but the number of the circular holes 41 needs to be determined according to the size of the scraper 40, and the size of the scraper 40 is determined according to the specification of the die 50 or the grinding wheel. The larger the diameter of the grinding wheel is, the longer the length of the scraper 40 is, and the number of the circular holes 41 should be increased properly to ensure that the passing rate of the circular holes 41 through which the sand passes meets the requirement.

Referring to fig. 1 and 2, in some embodiments of the present invention, the scraper 40 further has a strip hole 42, the strip hole 42 extends along the horizontal direction, at least two fasteners 31 are disposed on the strip hole 42, and the scraper 40 is mounted on the fixing assembly 30 through the fasteners 31. In order to adapt the position of the blade 40 to different molds 50 and to match the position of the molds 50, the blade 40 is provided with a strip-shaped hole 42 extending in the horizontal direction. The scraper 40 can be fastened to the fixing member 30 by using the fastening member 31 through the strip-shaped hole 42. Loosening fastener 31 can loosen scraper 40, and then the position of scraper 40 can alternate along the direction of bar hole 42, so, scraper 40 that the position can change can be better the position of cooperation mould 50 for scraper 40 can shakeout the grit layer in mould 50 better.

It is understood that the fastening member 31 can be a well-known screw, and if the fastening member 31 is a screw, an internally threaded hole is formed in the fixing member 30 to be engaged with the fastening member 31. The scraper 40 is fixed to the fixing member 30 by passing the screw portion of the screw through the strip-shaped hole 42 of the scraper 40 and then screwing the screw portion of the screw into the internally threaded hole of the fixing member 30. If the scraper 40, the replacement scraper 40 or the position of the adjustment scraper 40 needs to be dismounted, the screw can be unscrewed and dismounted, and the scraper 40, the replacement scraper 40 or the position of the adjustment scraper 40 can be dismounted, so that the principle of fastening the scraper 40 is simple, the structure is simple, the operation is easy, the operation of technicians is convenient, and the working efficiency of grinding wheel forming can be improved.

Referring to fig. 1, in some embodiments of the present invention, the lifting assembly 20 includes a driving member 21 and a lifting bracket 22, the driving member 21 is installed on the frame 10, and an output end of the driving member 21 is connected to the lifting bracket 22. It can be understood that the fixing assembly 30 can move up and down under the driving of the lifting assembly 20, so that when the output end of the driving member 21 moves up and down, the lifting bracket 22 connected to the output end moves up and down synchronously under the driving of the driving member 21, thereby driving the scraper 40 mounted on the fixing assembly 30 to move up and down. When the output end of the driving member 21 drives the lifting bracket 22 to move downward, the lifting bracket 22 drives the fixing component 30 to move downward, so that the scraper 40 installed at the lower end of the fixing component 30 extends into the mold 50, the mold 50 moves horizontally, and the scraper 40 can flatten the sand layer. When the output end of the driving member 21 drives the lifting bracket 22 to move upward, the lifting bracket 22 drives the fixing component 30 to move upward, so that the scraper 40 installed at the lower end of the fixing component 30 can be lifted above the mold 50, the mold 50 can be moved to the next production station, and the other mold 50 which needs to flatten the sand layer is moved below the scraper 40. The scraper 40 is lifted to the upper side of the mould 50 to avoid the mould 50, so that the mould 50 can smoothly move to the next production station or enter the lower side of the scraper 40, the production line can rapidly and stably run, and the production efficiency of the grinding wheel is improved.

It is contemplated that the lifting bracket 22 may include a mounting plate 221 and a link 222, one end of the link 222 being removably coupled to the mounting plate 221 and the other end of the link 222 being removably coupled to the fixing assembly 30. Taking the above embodiment as an example, the output end of the driving member 21 is connected to the lifting bracket 22, that is, the output end of the driving member 21 is connected to the mounting plate 221, the mounting plate 221 is further connected to the connecting rod 222, and the connecting rod 222 is further detachably connected to the fixing assembly 30, so that when the output end of the driving member 21 performs lifting motion, the mounting plate 221 can be driven to perform lifting motion up and down, and further the fixing assembly 30 on the connecting rod 222 can be driven to perform lifting motion, and the scraper 40 can extend into or move out of the mold 50 during the lifting motion of the fixing assembly 30. The removable mounting assembly 30 facilitates the mounting of the lifting assembly 20 to the mounting assembly 30 and, at the same time, facilitates the replacement and maintenance of either the lifting assembly 20 or the mounting assembly 30.

Referring to fig. 1 and 3, in some embodiments of the present invention, the mold 50 includes a mold ring 51 and a bottom plate 52, the bottom plate 52 is placed on the lower portion inside the mold ring 51, when the scraper 40 is lowered into the mold 50, the outer side of the scraper 40 is located on the side of the inner wall of the mold ring 51, and the length of the scraper 40 is greater than or equal to the radius of the bottom plate 52. In order to avoid a gap between the edge of the outer side of the scraper 40 and the side of the inner wall of the die ring 51, so that the sand in the gap cannot be leveled by the scraper 40, the outer side of the scraper 40 should be pressed against the side of the inner wall of the die ring 51 as much as possible, and the length of the scraper 40 should be greater than or equal to the radius of the bottom plate 52 in order to enable the sand in the center of the die ring 51 to be leveled by the scraper 40.

It should be noted that there should also be a gap between the squeegee 40 and the base plate 52. The height of the gap should also be larger than the thickness of the finished grinding wheel, so as to ensure that the gap between the scraper 40 and the bottom plate 52 can be filled with enough grinding wheel sand, and the thickness of the pressed grinding wheel can meet the requirements of quality and performance.
