Specific implementation manner

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a grinding device for raw materials of a concrete crack-resistant waterproofing agent, including a grinding cylinder 1, a discharge pipe 2, a support plate 3, an electric telescopic rod 4, a mounting frame 5, a limit window 6, a servo motor 7, an output shaft 8, an upper grinding disc 9, a side grinding plate 10, a bottom column 11, a lower grinding disc 12, a grinding bump 13, a stirring plate 14 and a rolling ball 15. A discharge pipe 2 is installed at the bottom end of the grinding cylinder 1, a support plate 3 is fixed at the top end of the grinding cylinder 1, an electric telescopic rod 4 is fixedly installed on the top surface of the support plate 3, the top end of the electric telescopic rod 4 is connected and fixed to the top of the side of the mounting frame 5. The mounting frame 5 penetrates through the limit window 6. The limit window 6 is opened in the center of the support plate 3. A servo motor 7 is fixed in the mounting frame 5. An output shaft 8 is installed at the bottom end of the servo motor 7. The bottom end of the output shaft 8 is connected and fixed to the center of the top surface of the upper grinding disc 9. A side grinding plate 10 is inlaid and fixed in the middle of the inner wall of the grinding cylinder 1. A bottom column 11 is fixed at the bottom end of the upper grinding disc 9. The bottom column 11 penetrates through the central hole of the lower grinding disc 12. The lower grinding disc 12 is fixed at the bottom of the inner wall of the grinding cylinder 1. Grinding bumps 13 are arranged on the top surface of the lower grinding disc 12. A stirring plate 14 is fixedly installed on the side of the bottom column 11. A rolling ball 15 is fixedly installed at the bottom end of the bottom column 11.

[0021] In this example, the electric telescopic rods 4 are symmetrically distributed with respect to the mounting frame 5, and the mounting frame 5 is slidably connected to the limit window 6. The above structural design enables the electric telescopic rods 4 to stably drive the mounting frame 5 to move vertically along the limit window 6.

[0022] Both the top and bottom of the upper grinding disc 9 are set in a frustum shape. The inclination angle of the front view section of the top curved surface of the upper grinding disc 9 is greater than the inclination angle of the front view section of the bottom curved surface of the upper grinding disc 9. The above structural design ensures the smooth falling of the raw materials, and at the same time, in cooperation with the lower grinding disc 12, ensures the rotation grinding effect and smooth feeding.

[0023] The center of the side grinding plate 10 is on the same horizontal plane as the center of the vertical side of the upper grinding disc 9. The width of the side grinding plate 10 is greater than the width of the vertical side of the upper grinding disc 9. The above structural design enables the upper grinding disc 9 to cooperate with the side grinding plate 10 when rotating to grind the raw materials falling between the two in a rotating manner.

[0024] The lower grinding disc 12 is arranged in a ring shape. The outer edge of the top surface of the lower grinding disc 12 is higher than the inner edge of the top surface. Grinding bumps 13 are arranged at equal angles on the top surface of the lower grinding disc 12. The above structural design ensures that the raw materials can fall along the top surface of the lower grinding disc 12 and smoothly fall through the central hole of the lower grinding disc 12.

[0025] The stirring plates 14 are distributed at equal angles around the center of the rolling balls 15. The length of the stirring plates 14 is not less than 1 / 3 of the inner diameter of the grinding cylinder 1. The above structural design ensures the mixing effect of the raw materials and at the same time facilitates the smooth downward discharge of the raw materials with smaller particles to avoid blockage.

[0026] Working principle: When using this device, the raw materials to be ground are put in through the top of the grinding cylinder 1, and the raw materials slide down along the Figure 2 inclined plane at the top of the upper grinding disc 9 to the space between the outer side of the vertical surface at the edge of the upper grinding disc 9 and the inner side of the side grinding plate 10. Control the servo motor 7 to drive the output shaft 8 to rotate. The output shaft 8 drives the upper grinding disc 9, the bottom column 11, the stirring plates 14 and the rolling balls 15 to rotate stably in one direction. The upper grinding disc 9 grinds the raw materials between it and the side grinding plate 10;

[0027] Subsequently, the raw materials fall onto the lower grinding disc 12 and slide along the inclined plane at the top of the lower grinding disc 12 towards the center at the bottom. The grinding bumps 13 on the bottom surface of the rotating upper grinding disc 9 cooperate with the top surface of the lower grinding disc 12 to grind the raw materials again. Subsequently, the raw materials fall into the inner bottom of the grinding cylinder 1 through the central hole of the lower grinding disc 12 and are rotated and stirred by the stirring plates 14;

[0028] While the servo motor 7 is operating, the reciprocating motion of the symmetrically distributed electric telescopic rods 4 can be synchronously controlled to first slightly shorten and then extend and reset. When the electric telescopic rods 4 shorten, the mounting frame 5 is driven to slide vertically along the limit window 6, and the output shaft 8, the upper grinding disc 9, the stirring plate 14, and the rolling balls 15 all move slightly downward synchronously. A relative displacement is generated between the vertical side surface of the upper grinding disc 9 and the side grinding plate 10. While rotating and grinding, a force in the vertical direction is applied to the raw materials, performing vertical and rotational composite grinding on the raw materials to improve the grinding effect. At the same time, the bottom surface of the upper grinding disc 9 moves downward close to the grinding protrusions 13 on the top surface of the lower grinding disc 12, squeezing the raw materials between the two and performing extrusion and rotational grinding. The stirring plate 14 rotates while moving vertically, improving the mixing effect of the raw materials at the bottom. The rolling balls 15 also move downward while rotating, squeezing the raw materials at their bottoms to improve the rotational grinding effect. Subsequently, the electric telescopic rods 4 extend and reset, and a relative displacement is generated again between the vertical side surface of the upper grinding disc 9 and the side grinding plate 10 for composite grinding, and all components are reset. This process is repeated to perform efficient composite grinding and rotational mixing. Finally, the discharge pipe 2 is opened to discharge the ground and mixed raw materials. This is the working principle of the grinding device for the raw materials of the concrete crack-resistant waterproofing agent.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
