[0001] This utility model relates to the field of non-metallic mineral products technology, and in particular to a grinding device for non-metallic mineral products. Background Technology

[0002] Non-metallic mineral products refer to various products made from non-metallic minerals as the main raw materials through processing and manufacturing. They are diverse in type and performance, and are widely used in national economic construction. Non-metallic mineral products include materials such as limestone, gypsum, talc, vermiculite, silica, and barite. They are widely used in building materials, ceramics, chemicals, metallurgy, and preparation processes. Grinding technology is used in the processing of non-metallic mineral products.

[0022] Referring to Figures 1-6, this utility model provides a technical solution: a non-metallic mineral product grinding device, including a body 1, a door 2 rotatably connected to one side of the body 1 via a hinge, support legs 3 fixed at the four corners of the bottom of the body 1, a feed inlet 4 installed on the top of the body 1, two grinding rollers 5 installed inside the body 1, a support frame 6 slidably connected inside the body 1, a sieve plate 7 slidably connected inside the support frame 6, a handle 8 fixed to one side of the sieve plate 7, a lower housing 9 fixed to one side of the support frame 6, and an upper housing 10 fixed to one side of the sieve plate 7. A lower protrusion 11 is provided inside the lower housing 9, a rotating rod 12 is fixed to one end of the lower protrusion 11, an upper protrusion 13 is slidably connected to the top of the lower protrusion 11, and an elastic locking block 14 is fixed to the top of the upper protrusion 13. The upper housing 10 has a T-slot 15 inside that works with the elastic locking block 14. Push rods 17 are slidably connected to both sides inside the upper housing 10. One end of the push rod 17 is fixed with a push plate 18. By pushing the push plate 18, the push rod 17 is driven to squeeze the two ends of the elastic locking block 14. At this time, the rotating rod 12 is pulled to move the lower protrusion 11 in the direction of the rotating rod 12. The inclined surface of the lower protrusion 11 will generate a force on the upper protrusion 13, causing the upper protrusion 13 to move and drive the elastic locking block 14 away from the interior of the T-slot 15. Through the above settings, the aperture of the screen plate 7 can be flexibly adjusted according to different grinding requirements, which improves the adaptability and flexibility of the grinding device, enabling it to meet diverse production needs. At the same time, it facilitates the maintenance of the screen plate 7, improves grinding efficiency and product quality.

[0023] Referring to Figure 4, in this embodiment: a first slider 19 is fixed to the bottom of the lower protrusion 11, and a first groove 20 that works with the first slider 19 is provided inside the lower housing 9. By setting the structure of the first slider 19 and the first groove 20, the movement path of the lower protrusion 11 can be restricted to avoid deviation.

[0024] Referring to Figure 4, in this embodiment: a first spring 21 is fixed to one end of the lower protrusion 11 away from the rotating rod 12, and the other end of the first spring 21 is fixed to the inside of the lower housing 9. By setting the structure of the first spring 21, the lower protrusion 11 can be quickly pushed back to the initial position.

[0025] Referring to Figure 4, in this embodiment: both ends of the upper protrusion 13 are fixed with a second slider 22, and the interior of the lower housing 9 is provided with a second slide groove 23 that cooperates with the second slider 22. By setting the second slider 22 and the second slide groove 23, it is ensured that the upper protrusion 13 can move stably along the predetermined path.

[0026] Referring to Figures 2, 3, and 5, in this embodiment: two through holes 24 are opened at both ends of the top of the support frame 6; two fixing plates 25 are fixed inside the machine body 1 on both sides; fixing rods 26 are fixed at both ends of the top of the fixing plates 25; a second spring 27 is slidably connected to the surface of the fixing rods 26; one end of the second spring 27 is fixed to the fixing plate 25; and the other end of the second spring 27 is fixed to the support frame 6. By setting the fixing plates 25, fixing rods 26, and second springs 27, the accumulation and clogging of materials on the screen plate 7 can be effectively reduced, and the materials can be evenly distributed on the screen plate 7, thereby improving the screening efficiency.

[0027] Referring to Figures 1 and 6, in this embodiment: a rotating shaft 28 is rotatably connected inside the feed inlet 4, and a spiral blade 29 is installed on the surface of the rotating shaft 28. By setting the rotating shaft 28 and the spiral blade 29, the material can smoothly enter the grinding chamber. The rotational motion of the blades reduces the accumulation and blockage of the material at the feed inlet 4.

[0028] Referring to Figure 2, in this embodiment: a collection box 30 is slidably connected inside the machine body 1. The collection box 30 is located below the support frame 6. By setting the collection box 30, the ground material can be collected conveniently, which improves the convenience and safety of operation.

[0029] Working principle: The user pushes the push plate 18 to drive the push rod 17 to squeeze both ends of the elastic block 14. At this time, the rotating rod 12 is pulled to move the lower protrusion 11 in the direction of the rotating rod 12. The inclined surface of the lower protrusion 11 will generate a force on the upper protrusion 13, causing the upper protrusion 13 to move and thus causing the elastic block 14 to move out of the T-slot 15. Through the above settings, the aperture of the screen plate 7 can be flexibly adjusted according to different grinding requirements, improving the adaptability and flexibility of the grinding device, enabling it to meet diverse production needs. At the same time, it facilitates the maintenance of the screen plate 7, improves grinding efficiency and product quality. By setting the structure of the first slider 19 and the first sliding groove 20, the movement path of the lower protrusion 11 can be adjusted. To prevent deviation, the structure of the first spring 21 allows the lower protrusion 11 to be quickly pushed back to its initial position. The second slider 22 and the second chute 23 ensure that the upper protrusion 13 can move stably along the predetermined path. The fixed plate 25, the fixed rod 26, and the second spring 27 effectively reduce the accumulation and blockage of materials on the screen plate 7, making the materials evenly distributed on the screen plate 7, thereby improving screening efficiency. The rotating shaft 28 and the spiral blades 29 allow the materials to enter the grinding chamber smoothly. The rotation of the blades reduces the accumulation and blockage of materials at the feed inlet 4. The collection box 30 allows for convenient collection of the ground materials, improving the convenience and safety of operation.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
