DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0021] In one embodiment, see Figure 1 , Figure 2 and Figure 3 , a magnesium oxide production grinding equipment, including a grinding cylinder 1, the top and bottom of the grinding cylinder 1 are both open, the outer wall of the grinding cylinder 1 is fixed with symmetrically distributed support plates 6, the bottom of the support plate 6 is fixed with a support column 7, the grinding cylinder 1 is provided with a grinding plate 12, the grinding plate 12 is provided with a grinding mechanism 4, the grinding mechanism 4 is used for grinding magnesium oxide, one of the support plates 6 is fixed with a mounting plate 8, the mounting plate 8 is fixed with a motor 9, the output end of the motor 9 is fixed with a rotating rod 13, the rotating rod 13 is connected with a vibration mechanism 5, the vibration mechanism 5 is used to drive the grinding plate 12 to vibrate up and down, a baffle 11 is fixed inside the grinding cylinder 1, a transmission rod 10 runs through the inside of the baffle 11, the transmission rod 10 is rotatably connected to the baffle 11, the lower end of the transmission rod 10 is connected to the rotating rod 13 through a transmission mechanism 2, the upper end of the transmission rod 10 is connected with a feeding mechanism 3, the feeding mechanism 3 is used for dispersing and feeding magnesium oxide.

[0022] In this embodiment, when the magnesium oxide is ground, the motor 9 drives the rotating rod 13 to rotate, and the rotating rod 13 drives the transmission rod 10 to rotate through the transmission mechanism 2. The transmission rod 10 drives the unloading mechanism 3 to operate on the one hand, and drives the grinding mechanism 4 to operate on the other hand. The magnesium oxide is dispersed and unloaded by the unloading mechanism 3, so that the magnesium oxide can fall evenly on the surface of the grinding plate 12, thereby avoiding the accumulation of magnesium oxide, and effectively improving the grinding effect of the grinding mechanism 4 on the magnesium oxide. In addition, while the rotating rod 13 rotates, it also drives the grinding plate 12 to vibrate back and forth through the vibration mechanism 5, thereby prompting the ground magnesium oxide to fall from the through hole inside the grinding plate 12, thereby avoiding the magnesium oxide blocking the grinding plate 12, thereby ensuring the grinding efficiency of the magnesium oxide.

[0023] See also Figure 3 The transmission mechanism 2 includes a first bevel gear 21 fixed to the outside of the rotating rod 13, and a second bevel gear 22 is fixed to the bottom of the transmission rod 10, and the second bevel gear 22 is meshed with the first bevel gear 21; When grinding magnesium oxide, the rotating rod 13 rotates while also driving the first bevel gear 21 to rotate, and the meshing of the first bevel gear 21 and the second bevel gear 22 drives the transmission rod 10 to rotate, so that the transmission rod 10 can drive the unloading mechanism 3 to operate, thereby realizing the dispersed unloading of magnesium oxide, so that the magnesium oxide can fall evenly on the surface of the grinding plate 12, ensuring the grinding effect of the grinding mechanism 4 on the magnesium oxide. In order to avoid the influence of the transmission rod 10 on the up and down vibration of the grinding plate 12, a circular hole is provided inside the grinding plate 12, and the transmission rod 10 passes through the inside of the circular hole.

[0024] See also Figure 1 The unloading mechanism 3 includes a conveying pipe 32 fixed to the top of the transmission rod 10 and arranged horizontally, a unloading hopper 31 is fixed to the top of the conveying pipe 32, the unloading hopper 31 is connected to the conveying pipe 32, and a unloading port is provided at the bottom of the conveying pipe 32; When grinding magnesium oxide, the magnesium oxide is poured into the lower hopper 31, and the magnesium oxide enters the conveying pipe 32 through the lower hopper 31, and is conveyed by the auger inside the conveying pipe 32, so that the magnesium oxide can fall from the discharge port (not shown in the figure) at the bottom of the conveying pipe 32. It is a prior art to convey magnesium oxide by the rotation of the auger, which will not be described in detail here. In addition, the transmission rod 10 also drives the conveying pipe 32 to rotate while the transmission rod 10 rotates, and the discharge port at the bottom of the conveying pipe 32 moves in a circle, so that the magnesium oxide falling from the discharge port can evenly fall on the surface of the grinding plate 12, thereby effectively improving the grinding effect of the grinding mechanism 4 on magnesium oxide.

[0025] See also Figure 2The grinding mechanism 4 includes a plurality of fixed rods 43 fixed to the outside of the transmission rod 10 and distributed in a circumference, and a grinding roller 42 is provided outside the fixed rod 43, and the grinding roller 42 is rotatably connected to the fixed rod 43; When the transmission rod 10 rotates, it drives multiple fixed rods 43 to rotate synchronously. The fixed rod 43 drives the grinding roller 42 outside it to make a circular motion. When the grinding roller 42 makes a circular motion, it rolls on the surface of the grinding plate 12, thereby grinding the magnesium oxide on the surface of the grinding plate 12. The transmission rod 10 drives the grinding roller 42 and multiple grinding rollers 42 to make a circular motion to grind the magnesium oxide, which can effectively improve the grinding effect of the magnesium oxide.

[0026] See also Figure 1 A circular groove 41 is provided on the inner wall of the grinding cylinder 1, and one end of the fixing rod 43 away from the transmission rod 10 is located inside the circular groove 41 and is slidably connected to the circular groove 41; The circular groove 41 can play a supporting and limiting role on the fixing rod 43, and effectively improves the stability of the grinding roller 42 during the circular motion.

[0027] See also Figure 2 and Figure 3 The vibration mechanism 5 includes a connecting block 51 fixed on the side wall of the grinding plate 12 and symmetrically distributed. The side wall of the grinding cylinder 1 is provided with a symmetrically distributed slideway. The connecting block 51 passes through the slideway and is slidably connected to the slideway. An extrusion plate 52 is fixed at one end of the connecting block 51 located outside the grinding cylinder 1. The extrusion plate 52 is connected to the support plate 6 through a buffer assembly. The buffer assembly is used for elastic support of the extrusion plate 52. An extrusion block 57 for extruding the extrusion plate 52 is fixed outside the rotating rod 13; When the rotating rod 13 rotates, the extrusion block 57 is driven to rotate. When the extrusion block 57 rotates to a certain extent, the extrusion block 57 squeezes the support plate 6, and the support plate 6 drives the grinding plate 12 to move upward through the connecting block 51. When the degree of the extrusion block 57 on the extrusion plate 52 is reduced, the extrusion plate 52 drives the grinding plate 12 to move downward through the connecting block 51 under the action of the buffer assembly. This cycle is repeated, so that the grinding plate 12 can continuously vibrate up and down, effectively avoiding the phenomenon that the magnesium oxide blocks the through holes inside the grinding plate 12, thereby ensuring the grinding efficiency of the magnesium oxide.

[0028] See also Figure 2 and Figure 4The buffer assembly includes a guide cylinder 55 fixed to the top of the support plate 6 and symmetrically distributed. The top of the guide cylinder 55 is connected to the bottom of the extrusion block 57 through a first elastic member 53. A symmetrically distributed guide rod 54 is fixed to the bottom of the support plate 6. The lower end of the guide rod 54 extends into the guide cylinder 55 and is slidably connected to the guide cylinder 55. A groove body is provided on the inner wall of the guide cylinder 55. A block 59 is slidably connected inside the groove body. One end of the block 59 is connected to the inner wall of the groove body through a second elastic member 510, and the other end of the block 59 is in contact with the outer wall of the guide rod 54. A groove 58 adapted to the block 59 is provided on the outside of the guide rod 54. The block 59 is connected to a traction component, which is used to pull the block 59 to the outside of the groove 58. When grinding magnesium oxide, the extrusion plate 52 moves upward and drives the guide rod 54 to move upward. When the extrusion block 57 squeezes the extrusion plate 52 to the highest point, the slot 58 on the side wall of the guide rod 54 is aligned with the block 59. The block 59 automatically enters the slot 58 under the action of the second elastic member 510. The block 59 fixes the guide rod 54 through the slot 58, and then fixes the grinding plate 12. Before the traction component pulls the block 59 to the outside of the slot 58, the grinding plate 12 is always at the highest point, so that the grinding roller 42 can always be aligned with the grinding plate 12 surface contact, increases the contact time between the grinding roller 42 and the surface of the grinding plate 12, and effectively improves the grinding efficiency of magnesium oxide. When the extrusion block 57 rotates to a certain extent, the extrusion block 57 pulls the card block 59 to the outside of the card slot 58 through the traction component. The fixation of the card block 59 is lost. The grinding plate 12 moves downward rapidly under the action of the connecting block 51, the extrusion plate 52 and the first elastic member 53, thereby generating vibration, which can effectively avoid the phenomenon that the magnesium oxide blocks the through hole inside the grinding plate 12, thereby ensuring the grinding efficiency of the magnesium oxide. The first elastic member 53 and the second elastic member 510 can both be springs.

[0029] See also Figure 4 The traction component includes a slide groove arranged on the side wall of the guide cylinder 55, a guide groove is arranged at the top of the slide groove, and the other end of the guide groove extends to the inside of the groove body, a push plate 56 is arranged between the guide cylinders 55, the end of the push plate 56 is located inside the slide groove and is slidably connected to the slide groove, the bottom of the push plate 56 is connected to the bottom of the slide groove through a third elastic member 512, and a traction rope 511 is fixed to the top of the push plate 56, and the traction rope 511 passes through the inside of the guide groove and is fixedly connected to the block 59; When the extrusion block 57 rotates to a certain extent, the extrusion block 57 squeezes the push plate 56, and the push plate 56 pulls the card to the outside of the card slot 58 through the traction rope 511, thereby releasing the fixation of the card block 59 on the guide rod 54, so that the grinding plate 12 can move downward quickly, effectively improving the vibration effect of the grinding plate 12, wherein the third elastic member 512 can be a spring, and when the extrusion block 57 no longer squeezes the push plate 56, the extrusion block 57 can automatically reset.

[0030] Working principle: When grinding magnesium oxide, the magnesium oxide is poured into the lower hopper 31, and the magnesium oxide enters the conveying pipe 32 through the lower hopper 31, and is conveyed by the auger inside the conveying pipe 32, so that the magnesium oxide can fall from the discharge port at the bottom of the conveying pipe 32, and at the same time, the rotating rod 13 is driven to rotate by the motor 9, and the rotating rod 13 drives the transmission rod 10 to rotate through the engagement of the first bevel gear 21 and the second bevel gear 22, and the transmission rod 10 drives the conveying pipe 32 to rotate, so that the magnesium oxide falling from the discharge port can fall evenly on the surface of the grinding plate 12, and the transmission rod 10 rotates while driving multiple fixed rods 43 to rotate synchronously, and the fixed rod 43 drives the grinding roller 42 outside it to make a circular motion, and the grinding roller 42 rolls on the surface of the grinding plate 12 while making a circular motion, so as to grind the magnesium oxide on the surface of the grinding plate 12, and the ground magnesium oxide falls directly from the through hole inside the grinding plate 12, When the extrusion block 57 rotates, the support plate 6 is pressed by the extrusion block 57, and the grinding plate 12 is driven upward by the support plate 6 through the connecting block 51. When the extrusion block 57 squeezes the extrusion plate 52 to the highest point, the clamping block 59 automatically enters the clamping slot 58, and the clamping block 59 fixes the guide rod 54 through the clamping slot 58, thereby fixing the grinding plate 12. As the extrusion block 57 continues to rotate, the extrusion block 57 squeezes the push plate 56, and the push plate 56 pulls the clamping block to the outside of the clamping slot 58 through the traction rope 511, thereby releasing the fixation of the guide rod 54 by the clamping block 59, thereby allowing the grinding plate 12 to move downward quickly. This cycle is repeated, so that the grinding plate 12 can continuously vibrate up and down, effectively avoiding the phenomenon that the magnesium oxide blocks the through hole inside the grinding plate 12, thereby ensuring the grinding efficiency of the magnesium oxide.
