[0031] Example 1

[0032] This embodiment provides a grinding device for preparing raw materials of zinc oxide, such as Figure 1 As shown, it includes a grinding machine body 1, a support column 2 is fixedly installed at the bottom of the grinding machine body 1, a motor 3 is fixedly installed at the top of the grinding machine body 1, and zinc oxide preparation raw materials are arranged inside the grinding machine body 1.

[0033] like Figure 2 and 3 As shown, a pretreatment component 5 is arranged inside the grinding machine body 1, and the pretreatment component 5 includes a vertical shaft 51, a slide groove 52, an upper pressure block 53, a sliding ball 54 and a lower pressure block 55. The top of the vertical shaft 51 is fixedly connected to the rotating shaft of the motor 3, and a slide groove 52 is opened on the vertical shaft 51. The slide groove 52 adopts a wavy structure. The inner ring of the upper pressure block 53 is fixedly installed with two symmetrically arranged sliding balls 54, and the sliding balls 54 slide in the slide groove 52. The lower pressure block 55 is arranged directly below the upper pressure block 53. The upper pressure block 53 slides up and down on the inner wall of the grinding machine body 1, and the bottom of the upper pressure block 53 contacts the lower pressure block 55.

[0034] The rotation of the vertical shaft 51 causes the upper pressing block 53 to move along the slide groove 52, so that the sliding ball 54 moves upward. When the upper pressing block 53 moves to the highest point of the slide groove 52, it then moves downward along the slide groove 52 under the action of gravity. The upper pressing block 53 and the sliding ball 54 continuously reciprocate up and down, and impact the zinc oxide preparation raw material between the upper pressing block 53 and the lower pressing block 55, and perform preliminary crushing, so that the large volume of zinc oxide preparation raw material is formed into a small volume of zinc oxide preparation raw material.

[0035] like Figure 2 and 3 As shown, the lower pressing block 55 adopts a truncated cone structure, the bottom surface of the upper pressing block 53 is provided with a truncated cone-shaped concave, and the top surface of the lower pressing block 55 contacts the bottom surface of the upper pressing block 53. The raw material for preparing zinc oxide between the lower pressing block 55 and the upper pressing block 53 can be clamped and collided. The raw material for preparing zinc oxide enters the interior of the grinding machine body 1 from the feed inlet 4, and then flows from the docking port 58 to between the upper pressing block 53 and the docking port 58. The small volume of raw material for preparing zinc oxide formed by the collision between the upper pressing block 53 and the docking port 58 flows from the top of the lower pressing block 55 and flows down along the inner wall of the grinding machine body 1.

[0036] like Figure 4 As shown, a support block 56 is fixedly installed between the upper pressing block 53 and the grinding machine body 1, and a plurality of support blocks 56 are provided, and the plurality of support blocks 56 are distributed in a circular manner with equal angles around the lower pressing block 55. After the collision, the small volume of zinc oxide preparation raw material falls from between two adjacent support blocks 56. The support block 56 adopts a triangular prism structure, and the bottom surface of the support block 56 is parallel to the horizontal plane. The small volume of zinc oxide preparation raw material remaining on the support block 56 will be vibrated and shaken off by the upper pressing block 53 hitting the lower pressing block 55 to avoid residual accumulation.

[0037] A buffer rubber is fixedly installed at the top center of the lower pressing block 55 to reduce the impact force of the upper pressing block 53 on the lower pressing block 55. A telescopic rod 57 is fixedly installed between the top of the upper pressing block 53 and the grinding machine body 1. The telescopic rod 57 guides the upper pressing block 53 to prevent the vertical shaft 51 from driving the upper pressing block 53 to rotate.

[0038] In this embodiment, the upper pressing block 53 is caused to reciprocate up and down by rotating the vertical shaft 51, and the upper pressing block 53 continuously impacts the zinc oxide preparation raw material between it and the lower pressing block 55 to perform pretreatment, thereby reducing the volume of the zinc oxide preparation raw material so that the zinc oxide preparation raw material can be ground, shortening the grinding time and improving the grinding efficiency.

[0039] Example 2

[0040] Based on Example 1, this example proposes a grinding device for preparing raw materials of zinc oxide, such as Figure 2 As shown, the inner wall of the grinding machine body 1 is rotatably connected with a grinding disc 6, the vertical shaft 51 passes through the center of the upper pressing block 53 and the lower pressing block 55, and its bottom end is fixedly connected to the grinding disc 6, and the distance from the bottom edge of the grinding disc 6 to the bottom center of the grinding disc 6 to the inner wall of the grinding machine body 1 gradually shortens.

[0041] A filter screen 7 is fixedly installed at the bottom center of the grinding machine body 1, and the filter screen 7 is used to screen the powder.

[0042] As the distance from the bottom edge of the grinding disc 6 to the bottom center of the grinding disc 6 to the inner wall of the grinding machine body 1 gradually shortens, the zinc oxide preparation raw material with a small volume will move toward the center of the grinding disc 6, while the zinc oxide preparation raw material with a large volume will be stuck by the bottom of the grinding disc 6 and the grinding machine body 1 and ground, so that the zinc oxide preparation raw materials of different sizes are at different positions at the bottom of the grinding disc 6.

[0043] The zinc oxide raw material with a large volume is ground near the edge of the bottom of the grinding disc 6, and the zinc oxide raw material with a small volume is ground near the center of the bottom of the grinding disc 6, so as to achieve the effect of layered grinding. The zinc oxide raw material with a small volume cannot achieve the grinding effect at the bottom of the grinding disc 6 near the edge. If it moves to the center of the grinding disc 6 at the same speed as the zinc oxide raw material with a large volume, it will not only reduce the grinding efficiency, but also affect the circulation speed of the zinc oxide raw material.

[0044] The zinc oxide raw material with a small volume will directly move to the center of the bottom of the grinding disc 6 and be ground, and finally discharged from the filter 7. The zinc oxide raw material with a large volume will be ground near the edge of the bottom of the grinding disc 6, and as it is ground, its volume will decrease, and then it will move to the center of the bottom of the grinding disc 6 and be ground.

[0045] like Figure 2 As shown, a chamfer is provided at the top edge of the grinding disc 6, and the top diameter of the grinding disc 6 is smaller than the bottom diameter of the lower pressing block 55, so that the small volume of zinc oxide preparation raw material sliding down from the top of the lower pressing block 55 slides down along the inner wall of the grinding machine body 1, and finally enters the bottom position of the grinding disc 6, and the small volume of zinc oxide preparation raw material is ground into powder by the grinding machine body 1 and the grinding disc 6.

[0046] In this embodiment, the distance from the bottom edge of the grinding disc 6 to the bottom center of the grinding disc 6 to the inner wall of the grinding machine body 1 is gradually shortened, so that the large-volume zinc oxide preparation raw material is ground at the bottom of the grinding disc 6 near the edge, and the small-volume zinc oxide preparation raw material is ground at the bottom of the grinding disc 6 near the center, thereby achieving the effect of layered grinding. If the small-volume zinc oxide preparation raw material and the large-volume zinc oxide preparation raw material move toward the center of the grinding disc 6 at the same speed, not only the grinding efficiency will be reduced, but also the circulation speed of the zinc oxide preparation raw material will be affected.

[0047] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
