DETAILED DESCRIPTION

[0032] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the present invention.

[0033] Example 1: A raw material mixing and refining device for fireworks manufacturing, such as Figures 1-5 As shown, it includes a frame 1, a vibration plate 11, a mixing barrel 12, a cover assembly 13, a cylinder 14, a limit frame 15, a first mounting frame 16, a lower pressure plate 17 and a pressure plate 18. The vibration plate 11 is rotatably connected to the left side of the top of the frame 1, the cover assembly 13 is fixed to the right side of the top of the vibration plate 11, and the mixing barrel 12 is clamped at the bottom of the cover assembly 13. The cylinder 14 is rotatably connected between the frame 1 and the vibration plate 11. The first mounting frame 16 is fixed to the inside of the mixing barrel 12. The limit frame 15 distributed longitudinally in the front and rear is fixed to the middle of the left side of the first mounting frame 16. The pressure plate 18 is fixed to the lower left side of the first mounting frame 16, and the lower pressure plate 17 is rotatably connected to the left side of the top of the pressure plate 18.

[0034] like Figures 2-4 As shown, the upper and lower sides of the limiting frame 15 are both wavy.

[0035] like Figure 4 and Figure 5 As shown, the right side of the pressure plate 18 is provided with an inclined surface and the entire plate is inclined downward.

[0036] When the workers need to mix and refine the raw materials needed to manufacture fireworks, they can first pour the various raw materials into the mixing barrel 12 according to the proportions, then install the mixing barrel 12 at the bottom of the cover assembly 13, and then start the air cylinder 14, which will extend and shorten back and forth, thereby driving the vibration plate 11 and other components to rotate up and down and produce vibration. During this process, the raw materials will not only gradually mix with each other, but also gradually rise to the top layer through the Brazil nut effect, and the small particle raw materials will sink to the bottom layer due to their smaller particle size and easier gap filling. The back and forth rotation of the vibration plate 11 and the mixing barrel 12 and other components will cause the raw materials on the right side to move to the left side, and the small particle raw materials will pass through the gap between the front and rear longitudinally distributed limiting frames 15, while the blocky raw materials will be sieved out and continue to move to the left until they enter the left part of the first mounting frame 16. At this time, the blocky raw materials will fall between the pressing plate 17 and the pressure plate 18, and since the gap between the pressure plate 18 and the first mounting frame 16 is small, the blocky raw materials will not directly fall back into the mixing barrel 12. Since the pressing plate 17 and the pressure plate 18 also swing up and down with the mixing barrel 12 and other components, and the pressing plate 17 is rotationally connected with the pressure plate 18, the pressing plate 17 will also rotate up and down relative to the pressure plate 18 and knock and crush the blocky raw materials between the pressing plate 17 and the pressure plate 18. Since the pressure plate 18 is inclined and the overall inclination is downward, the crushed and refined raw materials will pass through the gap between the pressure plate 18 and the first mounting frame 16 and fall back into the mixing barrel 12 under the action of gravity, thereby continuing to mix with other raw materials. In this way, not only can the Brazil nut effect be used to sieve out the blocky raw materials in the mixing barrel 12, but also the blocky raw materials originally contained in the raw materials and produced after mixing can be crushed and refined without affecting the mixing of the raw materials, thereby improving the refinement and mixing effects of the device. After the mixing and refining process is completed, the air cylinder 14 can be turned off, and then the mixing barrel 12 can be removed from the cover assembly 13 and the mixed and refined raw materials can be poured out.

[0037] Example 2: Based on Example 1, as shown in Figure 6 and Figure 7 a guide mechanism is also included, which is provided on the first mounting frame 16 and includes a turnover plate 2, a limiting block 21, and a telescopic rod 22. The limiting block 21 is fixedly connected to the top left side of the first mounting frame 16, and the telescopic rod 22 is fixedly connected to the right side of the first mounting frame 16. The telescopic ends of the front and rear telescopic rods 22 are fixedly connected to the turnover plate 2, which is slidingly connected to the limiting block 21 and the mixing barrel 12.

[0038] When the components such as the vibration plate 11 and the mixing barrel 12 are turned up and down under the action of the air cylinder 14, the turnover plate 2 will not only be turned up and down with the first mounting frame 16, but also will be moved up and down relative to the mixing barrel 12 under the action of inertia, and the telescopic rod 22 will be extended and shortened accordingly, so as to intermittently push the raw materials on the right side of the mixing barrel 12, thereby accelerating the mixing efficiency of the raw materials and improving the mixing effect of the raw materials, and better pushing the raw materials on the right upper side to the left side, thereby promoting the left and right circulation of the raw materials on the upper side of the mixing barrel 12, to improve the screening efficiency of the limiting frame 15 on the block-shaped raw materials, and the existence of the limiting block 21 can avoid the raw materials entering the gap between the turnover plate 2 and the first mounting frame 16 and being difficult to take out.

[0039] As shown in Figure 8 and Figure 9 , it further comprises a pushing mechanism, which is arranged on the first mounting frame 16, and the pushing mechanism comprises a second mounting frame 3, a moving frame 31, a pushing block 32, a guide cylinder 33 and a rolling ball 34, the second mounting frame 3 is fixedly connected to the top left side of the first mounting frame 16, the moving frame 31 is slidably connected to the middle of the second mounting frame 3, the pushing block 32 is fixedly connected to the bottom of the moving frame 31, the guide cylinder 33 is fixedly connected to the front and rear sides of the moving frame 31, and the rolling ball 34 is movably connected inside the guide cylinder 33.

[0040] As shown in Figure 8 and Figure 9 , wherein the guide cylinder 33 is inclinedly arranged, and the left side is high and the right side is low.

[0041] When the components such as the vibration plate 11, the mixing barrel 12 and the first mounting frame 16 are turned up under the action of the air cylinder 14, the components such as the second mounting frame 3, the moving frame 31 and the guide cylinder 33 will also be turned up with the first mounting frame 16, and the guide cylinder 33 will become left low and right high after being turned up, at this time the rolling ball 34 originally located on the right side of the guide cylinder 33 will move left and down under the action of gravity and hit the left inner wall of the guide cylinder 33, and the components such as the moving frame 31, the pushing block 32 and the guide cylinder 33 will also move left and down under the action of gravity and the rolling ball 34, wherein the left and down movement of the pushing block 32 can push the block-shaped raw materials on the upper side of the mixing barrel 12 to the limiting frame 15 and the first mounting frame 16, thereby improving the screening efficiency and effect of the limiting frame 15 on the block-shaped raw materials, and when the components such as the vibration plate 11, the mixing barrel 12 and the first mounting frame 16 are turned down and reset under the action of the air cylinder 14, the guide cylinder 33 will become left high and right low again, at this time the rolling ball 34 located on the left side of the guide cylinder 33 will move right and down under the action of gravity and centrifugal force and hit the right inner wall of the guide cylinder 33, and the components such as the moving frame 31, the pushing block 32 and the guide cylinder 33 will also move right and reset under the action of centrifugal force and the rolling ball 34.

[0042] As shown in Figure 2 andFigure 10 As shown, a disturbance mechanism is also included, which is arranged in the mixing barrel 12. The disturbance mechanism includes a slide rod 4 and a moving block 41. The two slide rods 4 are respectively fixed to the front and rear sides of the mixing barrel 12, and the outside of the slide rod 4 is slidably connected to the axially distributed moving block 41.

[0043] When the vibration plate 11 and the mixing barrel 12 and other components rotate up and down back and forth under the action of the cylinder 14, the slide rod 4 will also rotate up and down back and forth with the mixing barrel 12, and the moving block 41 distributed axially outside the slide rod 4 will swing back and forth left and right under the action of gravity and centrifugal force, thereby stirring the raw materials in the mixing barrel 12, thereby accelerating the mixing efficiency of the raw materials and improving the mixing effect of the raw materials.

[0044] like Figure 11 and Figure 12 As shown, it also includes a displacing mechanism, which is arranged on the first mounting frame 16. The displacing mechanism includes a rotating plate 5, a torsion spring 51 and a counterweight 52. The rotating plate 5 is rotatably connected to the lower left part of the first mounting frame 16. Two front and rear torsion springs 51 are fixed between the rotating plate 5 and the first mounting frame 16. The rotating plate 5 is in contact with the pressure plate 18, and the counterweight 52 is slidably connected to the front and rear sides of the rotating plate 5.

[0045] When the vibration plate 11 and the mixing barrel 12 and other components rotate up and down and back and forth under the action of the cylinder 14, the counterweight block 52 will slide up and down inside the rotating plate 5 under the action of centrifugal force and drive the rotating plate 5 to swing back and forth relative to the first mounting frame 16. The torsion spring 51 will then deform and restore back and forth, so that part of the raw materials on the left side of the mixing barrel 12 can be intermittently pushed to the right by the rotating plate 5 that swings back and forth, thereby providing sufficient falling space for the refined block raw materials, so that the refined block raw materials can continue to be mixed with other raw materials. There is a limit groove at the bottom of the pressure plate 18 for limiting the rotation angle of the rotating plate 5. After the mixing and refining process is completed, the rotating plate 5 will swing to the left and return to its original shape under the action of the torsion spring 51.

[0046] It should be understood that the above description is only for illustrative purposes and is not intended to limit the present invention. Those skilled in the art will appreciate that variations of the present invention will fall within the scope of the claims herein.
