[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] Example 1

[0035] The present application embodiment discloses a jade porcelain raw material processing process, comprising the following steps:

[0036] (1) using melamine and formaldehyde as raw materials to react to obtain a melamine formaldehyde resin fluid; and feeding the obtained fluid into a mixing device;

[0037] (2) adding fillers, pigments and other powders to the melamine formaldehyde resin fluid obtained in step (1), and mixing them uniformly in a mixing device to obtain a mixture;

[0038] (3) Drying, crushing and grinding the mixed material in step (2) to obtain resin powder.

[0039] Example 2

[0040] This embodiment discloses a mixing device for uniformly mixing powder materials such as fillers in a fluid. Figure 1 and Figure 2 The mixing device comprises a cylinder 1 and a cover 2 mounted on the cylinder 1, and the cover 2 is fixed to the cylinder 1 by bolts or the like. An extension rod 3 is fixed at the center of the cover 2, and the extension rod 3 extends into the inner cavity of the cylinder 1. The upper end side wall of the cylinder 1 is a feed inlet for the fluid, and the lower end face of the cylinder 1 is a discharge outlet for the fluid, and corresponding opening and closing valves can be set corresponding to the feed inlet and the discharge outlet to control opening and closing.

[0041] A hollow material receiving cylinder 4 is installed on the side of the cover body 2 facing the cylinder body 1. The material receiving cylinder 4 is annular in structure, and the material receiving cylinder 4 and the extension rod 3 are coaxially arranged. The material receiving cylinder 4 is used to fill powders such as fillers and pigments. The material receiving cylinder 4 is detachably mounted on the cover body 2 by means of bolts, etc., so as to facilitate the filling of powders in the material receiving cylinder 4. A discharge piece 5 is installed on the bottom surface of the material receiving cylinder 4, and a plurality of discharge pieces 5 are evenly arranged along the circumference of the material receiving cylinder 4. The discharge piece 5 is used to control the powder to fall into the cylinder body 1.

[0042] Combination Figure 3 and Figure 4 A rotating cylinder 6 is rotatably mounted on the outer wall of the extension rod 3, a triggering member 7 is mounted on the outer wall of the rotating cylinder 6, and a driving member 8 for driving the rotating cylinder 6 to rotate is also mounted on the cover body 2. When the rotating cylinder 6 rotates, the triggering member 7 can drive the unloading member 5 to move, so that the powder in the receiving cylinder 4 falls into the cylinder body 1. A mixing rod 9 is also mounted on the outer wall of the lower end of the rotating cylinder 6, and the mixing rod 9 is located below the liquid level of the fluid in the cylinder body 1. When the rotating cylinder 6 rotates, the mixing rod 9 disturbs the fluid, and then the triggering member 7 drives the unloading member 5 to discharge the material, so that when the powder falls into the fluid, it can be better dispersed.

[0043] Reference Figure 3 , a slot 12 is provided on the bottom surface of the receiving barrel 4, and the slot 12 passes through the bottom surface of the receiving barrel 4, and multiple slots 12 are evenly arranged along the circumference of the receiving barrel 4. The unloading member 5 includes a semi-cylinder 51 rotatably installed in the slot 12, and a rotating shaft 13 is fixed on both end surfaces of the semi-cylinder 51. The semi-cylinder 51 rotates in the slot 12 through the rotating shaft 13, and the axial direction of the semi-cylinder 51 extends along the radial direction of the receiving barrel 4. One end of the rotating shaft 13 extends in the direction of the extension rod 3 and passes through the surface of the receiving barrel 4, and a gear 14 is coaxially fixed on its outer wall. In the natural state, the opening of the semi-cylinder 51 faces upward, and the upper surface of the semi-cylinder 51 is flush with the inner bottom surface of the receiving barrel 4. The trigger member 7 includes a trigger rod 71 fixed on the outer wall of the rotating barrel 6, and a tooth 72 is provided on the upper surface of the end of the trigger rod 71 away from the rotating barrel 6. When the rotating cylinder 6 rotates, the teeth 72 and the gear 14 mesh, and can drive the semi-cylinder 51 to flip 180 degrees, so that the powder in the semi-cylinder 51 falls downward. When the teeth 72 and the gear 14 are out of contact, the semi-cylinder 51 returns to its original position under the action of its own weight.

[0044] Further, see Figure 1A bracket 15 is fixed on the upper surface of the cover body 2, and a certain space is formed between the bracket 15 and the cover body 2. The upper end of the extension rod 3 is fixed on the bracket 15. The rotating cylinder 6 rotates and penetrates the surface of the cover body 2. A worm wheel 16 is coaxially fixed to the upper end of the rotating cylinder 6. The driving member 8 includes a worm 81 rotatably connected to the cover body 2 through a bearing seat. The worm 81 is meshed with the worm wheel 16. A power source 82 is installed on the cover body 2. The power source 82 is a motor. The motor drives the worm 81 to rotate, which can drive the rotating cylinder 6 to rotate.

[0045] Reference Figure 4 The lower end of the extension rod 3 is rotatably mounted with a mixing drum 10, which can be rotated on the outer wall of the extension rod 3 by means of a bearing or the like. A plurality of mixing rods 19 are arranged at intervals on the outer wall of the mixing drum 10, and the mixing rods 19 extend in the radial direction of the mixing drum 10, and the mixing rods 19 are arranged in a staggered manner. A linkage 11 is installed on the outer wall of the extension rod 3, and the rotating drum 6 rotates, which can synchronously drive the mixing drum 10 to rotate, and the rotation direction of the mixing drum 10 is opposite to that of the rotating drum 6, so that the disturbance direction of the lower layer fluid is opposite to that of the upper layer fluid, which promotes the distribution of the powder in the fluid.

[0046] The linkage 11 includes a conical tooth rotatably mounted on the outer wall of the extension rod 3. The conical tooth is rotated on the outer wall of the extension rod 3 through a circular shaft, and the rotation axis of the conical tooth is perpendicular to the length direction of the extension rod 3. The lower end of the rotating drum 6 and the upper end of the mixing drum 10 are both provided with a meshing gear 20, and the meshing gear 20 is meshed with the conical tooth. When the rotating drum 6 rotates, the mixing drum 10 can be driven to rotate in the opposite direction through the conical tooth.

[0047] Reference Figure 3 , a tilting block 17 is fixed on the side of the material receiving barrel 4 facing the extension rod 3, and a plurality of tilting blocks 17 are evenly arranged along the circumference of the material receiving barrel 4. The tilting block 17 includes an inclined surface 171 and a stepped surface 172, and an elastic telescopic rod 18 is horizontally installed on the outer wall of the rotating barrel 6. When the rotating barrel 6 rotates, the elastic telescopic rod 18 is compressed by the inclined surface 171. When it moves to the stepped surface 172, the elastic telescopic rod 18 and the inclined surface 171 are out of contact, and the elastic telescopic rod 18 can pop out and knock on the side wall of the material receiving barrel 4, thereby promoting the powder in the material receiving barrel 4 to be better filled into the semi-cylinder 51. Furthermore, the part of the material receiving barrel 4 located between the two slots 12 can be a structure with a high middle and low sides, which is conducive to the powder flowing into the semi-cylinder 51.

[0048] The elastic telescopic rod 18 includes a fixed cylinder 181 fixed on the outer wall of the rotating cylinder 6, a sliding rod 182 slidably inserted in the fixed cylinder 181, and an elastic member 183 installed in the fixed cylinder 181. The elastic member 183 is a spring, one end of which is connected to the inner end surface of the fixed cylinder 181, and the other end is connected to the end surface of the sliding rod 182. When the end of the sliding rod 182 abuts against the inclined surface 171, the sliding rod 182 slides into the fixed cylinder 181, and the spring is compressed.

[0049] The implementation principle of a mixing device in the embodiment of the present application is as follows: when the rotating cylinder 6 rotates, the powder can intermittently fall into the cylinder 1, and the powder can be dispersed under the action of the mixing rod 9. Then, under the action of the stirring rod 19, the fluid is mixed in the opposite direction of the mixing rod 9, thereby improving the uniformity of the distribution of the powder in the fluid.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
