When the second motor 17 is started, the second rotating shaft 19 and the cams 110 will rotate. When the cams 110 rotate, they will come into contact with the sealing plates 18 and squeeze a pair of sealing plates 18. The sealing plates 18 will move away from each other under the squeezing action of the cams 110 and be in an open state. The materials at the feed inlet 16 will flow into the interior of the tank body 1 through the feed inlet 16 when the sealing plates 18 are opened. Subsequently, the cams 110 will continue to rotate and move away from the sealing plates 18. The sealing plates 18 will reset under the elastic force of the torsion springs and re-close the feed inlet 16 until the cams 110 squeeze the sealing plates 18 again. When the first motor 12 is started, the first rotating shaft 13 will drive the sector blades 14 and the stirring rods 15 to rotate. When the sector blades 14 rotate, they will convey the materials, and when the stirring rods 15 rotate, they will mix the materials. Finally, the mixed materials will be discharged from the discharge port of the tank body 1; when the cams 110 rotate, they will intermittently squeeze the sealing plates 18, so that the sealing plates 18 can intermittently open and close the feed inlet 16, and the materials will uniformly and quantitatively flow into the interior of the tank body 1 from the feed inlet 16, improving the stability of the device for mixing materials.
[0027] Please refer to Figure 4 and Figure 5As shown, a plurality of first springs 2 are fixedly connected to the middle of the cam 110; a baffle 22 is fixedly connected to the end of the first spring 2; when the cam 110 contacts the sealing plate 18, the baffle 22 also contacts the sealing plate 18, and the baffle 22 transmits the pressure to the first spring 2 to make the first spring 2 in a compressed state. The baffle 22 moves with the first spring 2 until it contacts the cam 110. Subsequently, the baffle 22 squeezes the sealing plate 18 under the elastic force of the first spring 2 and the extrusion of the cam 110, reducing the direct contact between the sealing plate 18 and the cam 110; when the baffle 22 contacts the sealing plate 18, it moves towards the cam 110 with the first spring 2, reducing the impact generated when the cam 110 contacts the sealing plate 18, and reducing the wear caused by frictional extrusion on the surface when the cam 110 contacts the sealing plate 18.
[0028] Please refer to Figure 5 As shown, a plurality of balls 3 are rotatably connected to the middle of the baffle 22; the balls 3 are arranged in an array; when the baffle 22 contacts the sealing plate 18, the balls 3 also contact the sealing plate 18, and the balls 3 rotate under the action of friction. The balls 3 reduce the frictional force between the baffle 22 and the sealing plate 18, and reduce the wear caused by contact between the baffle 22 and the sealing plate 18.
[0029] Please refer to Figure 4 and Figure 6 As shown, a plurality of first vertical plates 4 are fixedly connected to the top of the sealing plate 18; a plurality of second vertical plates 42 are fixedly connected to the top of the sealing plate 18; a second spring 44 is fixedly connected to the middle of the first vertical plate 4; a slider 43 is fixedly connected to the end of the second spring 44; the slider 43 is slidably connected to the sealing plate 18; the slider 43 and the second vertical plate 42 are correspondingly arranged; when the sealing plate 18 rotates along the feed port 16 under the extrusion of the cam 110, the slider 43 slides along the surface of the sealing plate 18 under the action of gravity until the slider 43 collides with the second vertical plate 42. The slider 43 transmits the vibration to the sealing plate 18, so that the materials attached to the surface of the sealing plate 18 can accelerate to fall off. When the sealing plate 18 resets, the slider 43 resets under the elastic force of the second spring 44.
[0030] Please refer to Figures 1 to 3As shown, a heating plate 5 is fixedly connected to the inner side wall of the tank body 1; a trachea 52 is communicated with the top of the heating plate 5; the trachea 52 and the tank body 1 are arranged in a penetrating manner; a plurality of round holes 53 are formed in the middle of the heating plate 5; during operation, the trachea 52 will be externally connected to a hot air blower, and the hot air flow will enter the inside of the heating plate 5 through the trachea 52 and spray out from the round holes 53. The hot air flow will enter the inside of the tank body 1 and heat the material, improving the fluidity of the material. At the same time, the air flow will reach the surfaces of the sector blades 14 and the stirring rods 15 and clean them, reducing the material adhering to the surfaces of the sector blades 14 and the stirring rods 15.
[0031] Please refer to Figure 3 As shown, a scraping plate 6 is fixedly connected to the end of adjacent stirring rods 15; a plurality of cleaning rods 62 are fixedly connected to the middle of the scraping plate 6; when the stirring rods 15 rotate, they will drive the scraping plate 6 and the cleaning rods 62 to rotate together. The cleaning rods 62 will clean the inner wall of the tank body 1 and the surface of the heating plate 5, reducing the raw materials adhering to their surfaces.
[0032] Please refer to Figure 6 As shown, a buffer pad 7 is fixedly connected to the middle of the second vertical plate 42; the buffer pad 7 is located on the top of the sealing plate 18; when the slider 43 collides with the second vertical plate 42, it will come into contact with the buffer pad 7. Since the buffer pad 7 is made of a flexible material, the buffer pad 7 will absorb the impact generated when the second vertical plate 42 and the slider 43 collide, reducing the damage caused by the collision between the second vertical plate 42 and the slider 43.
[0033] Working principle: Pour the raw materials into the interior of the tank body 1 through the feed inlet 16. At the same time, start the second motor 17 and the first motor 12. When the second motor 17 starts, the second rotating shaft 19 and the cam 110 will rotate. When the cam 110 rotates, it will come into contact with the sealing plate 18 and extrude a pair of sealing plates 18. The sealing plates 18 will move away from each other under the extrusion of the cam 110 and be in an open state. The materials at the feed inlet 16 will flow into the interior of the tank body 1 through the feed inlet 16 when the sealing plates 18 are opened. Subsequently, the cam 110 will continue to rotate and move away from the sealing plate 18. The sealing plate 18 will reset under the elastic force of the torsion spring and close the feed inlet 16 again until the cam 110 extrudes the sealing plate 18 again. When the first motor 12 starts, the first rotating shaft 13 will drive the sector blade 14 and the stirring rod 15 to rotate. When the sector blade 14 rotates, it will convey the materials. When the stirring rod 15 rotates, it will mix the materials. Finally, the well-mixed materials will be discharged from the discharge port of the tank body 1; when the cam 110 comes into contact with the sealing plate 18, the baffle 22 will also come into contact with the sealing plate 18. The baffle 22 will transfer the pressure to the first spring 2, causing the first spring 2 to be in a compressed state. The baffle 22 will move together with the first spring 2 until it comes into contact with the cam 110. Subsequently, the baffle 22 will extrude the sealing plate 18 under the elastic force of the first spring 2 and the extrusion of the cam 110, reducing the direct contact between the sealing plate 18 and the cam 110; when the baffle 22 comes into contact with the sealing plate 18, the ball 3 will also come into contact with the sealing plate 18. The ball 3 will rotate under the action of friction, and the ball 3 will reduce the frictional force between the baffle 22 and the sealing plate 18; under the extrusion of the cam 110, the sealing plate 18 will rotate along the feed inlet 16. At this time, the slider 43 will slide along the surface of the sealing plate 18 under the action of gravity until the slider 43 collides with the second vertical plate 42. The slider 43 will transfer the vibration to the sealing plate 18, enabling the materials attached to the surface of the sealing plate 18 to fall off more quickly; during operation, the air pipe 52 will be externally connected to a hot air blower. The hot air flow will enter the interior of the heating plate 5 through the air pipe 52 and spray out from the round holes 53. The hot air flow will enter the interior of the tank body 1 and heat the materials, improving the fluidity of the materials. At the same time, the air flow will reach the surfaces of the sector blade 14 and the stirring rod 15 and clean them; when the stirring rod 15 rotates, it will drive the scraping plate 6 and the cleaning rod 62 to rotate together. The cleaning rod 62 will clean the inner wall of the tank body 1 and the surface of the heating plate 5; when the slider 43 collides with the second vertical plate 42, it will come into contact with the buffer pad 7. Since the buffer pad 7 is made of a flexible material, the buffer pad 7 will absorb the impact generated when the second vertical plate 42 and the slider 43 collide.
