DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1: Figure 1-Figure 3 As shown, the technical solution adopted by the utility model is as follows: the flat die pellet machine dividing device includes a bottom plate 1, a screening cylinder 2 and a conveying cylinder 15.

[0026] The screening drum 2 and the conveying drum 15 are both fixedly mounted on the bottom plate 1 through supporting legs. A feeding port is provided at the upper end of the screening drum 2, and a discharge port is provided at the lower end. A storage barrel 14 is provided on the bottom plate 1, and the storage barrel 14 is connected to the discharge port. A screening mechanism is provided in the screening drum 2. The material is added into the screening drum 2 through the feeding port, and enters the storage barrel 14 after being screened by the screening mechanism.

[0027] A rotating shaft 4 is rotatably arranged in the screening cylinder 2. Specifically, a first motor 3 is fixedly installed on the bottom plate 1, and the motor shaft of the first motor 3 is vertically arranged, and the lower end of the rotating shaft 4 penetrates the screening cylinder 2 and extends to the outside of the screening cylinder 2. The motor shaft of the first motor 3 is coaxially fixedly connected with the rotating shaft 4.

[0028] The screening mechanism is arranged on the rotating shaft 4 for moving up and down, and a linkage assembly for driving the screening mechanism to move up and down is arranged on the rotating shaft 4. When the rotating shaft 4 rotates, the screening mechanism rotates with the rotating shaft 4, and at the same time, under the action of the linkage assembly, the screening mechanism moves up and down, so that the screening mechanism vibrates, which helps the material to pass through the screening mechanism smoothly, and less material is accumulated above the screening mechanism, which is conducive to improving the screening efficiency.

[0029] The screening mechanism includes a first screen 5 and a second screen 24. The first screen 5 and the second screen 24 are both in a cone shape with the tip pointing upward. The first screen 5 is located above the second screen 24. When the material is screened by the first screen 5 for the first time, larger particles are screened out, and then after the second screening by the second screen 24, the material enters the storage barrel 14 through the discharge port.

[0030] The first screen 5 is installed on the upper end of the rotating shaft 4 through an elastic telescopic member, and the second screen 24 is fixedly sleeved on the rotating shaft 4 .

[0031] The elastic telescopic member includes a telescopic rod 22 and a spring 23. The lower end of the telescopic rod 22 is fixed to the upper end of the rotating shaft 4, and the upper end of the telescopic rod 22 is fixedly connected to the first screen 5. The spring 23 is sleeved on the telescopic rod 22, and the spring 23 is fixedly connected between the first screen 5 and the second screen 24.

[0032] The linkage assembly includes a first bevel gear 6, a second bevel gear 8 and a cam 9. The first bevel gear 6 is coaxially fixedly sleeved on the rotating shaft 4. A connecting rod 7 is rotatably connected to the rotating shaft 4, and the axis of the connecting rod 7 is perpendicular to the axis of the rotating shaft 4. The second bevel gear 8 is coaxially fixedly sleeved on the connecting rod 7, and the second bevel gear 8 is meshed with the first bevel gear 6. The cam 9 is coaxially fixedly sleeved on the connecting rod 7. When the rotating shaft 4 rotates, under the action of the first bevel gear 6 and the second bevel gear 8, the connecting rod 7 rotates, and then the cam 9 rotates. Under the action of the cam 9, the first screen 5 reciprocates up and down, so that the first screen 5 has an up and down vibration effect, which is conducive to the smooth passage of the material through the first screen 5, avoiding the accumulation of material above the first screen 5, and is conducive to improving the screening efficiency.

[0033] The conveying drum 15 is arranged at one side of the screening drum 2, and a conveying dragon 11 is rotatably arranged in the conveying drum 15. A second motor 10 is fixedly installed on the bottom plate 1, and the motor shaft of the second motor 10 is arranged vertically upward, and the motor shaft of the second motor 10 is coaxially fixedly connected with the conveying dragon 11. The upper end of the conveying drum 15 is connected to the upper part of the screening drum 2 through the feed pipe 13, and the lower end of the conveying drum 15 is connected to the lower part of the screening drum 2 through the discharge pipe 12. The discharge pipe 12 and the feed pipe 13 are both arranged obliquely, and the lower end of the discharge pipe 12 is connected to the conveying drum 15, and the higher end of the feed pipe 13 is connected to the conveying drum 15. One end of the feed pipe 13 close to the screening drum 2 is above the tip of the first screen 5, and one end of the discharge pipe 12 close to the screening drum 2 is above the lower end of the second screen 24 and is arranged in coordination with the lower end of the second screen 24.

[0034] Working principle: Add materials into the screening cylinder 2 through the feeding port.

[0035] Start the first motor 3, the shaft 4 rotates, and when the shaft 4 rotates, the first screen 5 and the second screen 24 rotate synchronously. Under the action of the first bevel gear 6 and the second bevel gear 8, the connecting rod 7 rotates and the cam 9 rotates. Under the action of the cam 9, the telescopic rod 22 and the spring 23, the first screen 5 moves up and down reciprocatingly, and then the first screen 5 vibrates up and down, which is conducive to the smooth passage of the material through the first screen 5 and better screening of the material. The material screened by the first screen 5 falls on the second screen 24, and after being screened by the second screen 24, it enters the storage barrel 14 through the discharge port.

[0036] At the same time, the second motor 10 is started to rotate the conveying dragon 11. The material left on the second screen 24 enters the conveying cylinder 15 through the discharge pipe 12, and the conveying dragon 11 conveys the material in the conveying cylinder 15 to the upper end of the conveying cylinder 15, and then enters the screening cylinder 2 again through the feed pipe 13 for screening.

[0037] Example 2: Figure 4 , Figure 5 , Figure 6 As shown, this embodiment only introduces the parts that are different from those in Embodiment 1, and the same parts are not repeated here.

[0038] The linkage assembly includes a hemispherical second protrusion 25 and a first protrusion 21. A fixed sleeve 16 is rotatably sleeved on the rotating shaft 4, and the fixed sleeve 16 is fixedly connected to the screening cylinder 2. Specifically, the fixed sleeve 16 can be fixedly connected to the screening cylinder 2 by a fixed rod, and the fixed rod is not drawn in the figure. The upper end surface of the fixed sleeve 16 extends into the screening cylinder 2. And the upper end surface of the fixed sleeve 16 is fixedly connected with a plurality of second protrusions 25, and the plurality of second protrusions 25 are arranged at intervals. A movable sleeve 17 is slidably sleeved on the rotating shaft 4. A slide groove 27 is provided on the movable sleeve 17, and a slider 26 is fixedly connected to the rotating shaft 4, and the slider 26 is slidably arranged in the slide groove 27. The first protrusion 21 is fixedly connected to the lower end surface of the movable sleeve 17. The first screen 5 and the second screen 24 are both fixedly connected to the movable sleeve 17.

[0039] When the rotating shaft 4 rotates, the movable sleeve 17 rotates synchronously. When the first protrusion 21 contacts the second protrusion 25, the first protrusion 21 moves upward along the second protrusion 25, and the movable sleeve 17, the first screen 5 and the second screen 24 move upward. After the first protrusion 21 moves to the top of the second protrusion 25, under the action of the gravity of the movable sleeve 17, the first screen 5 and the second screen 24, the first protrusion 21 moves downward along the second protrusion 25. Under the action of multiple second protrusions 25, the movable sleeve 17 intermittently moves up and down, thereby causing the first screen 5 and the second screen 24 to produce a vibration effect.

[0040] A transmission assembly is provided between the rotating shaft 4 and the conveying dragon 11. When the rotating shaft 4 rotates, the rotating shaft 4 drives the conveying dragon 11 to rotate synchronously through the transmission assembly. The transmission assembly includes a first pulley 18, a belt 19 and a second pulley 20. The first pulley 18 is fixedly sleeved on the rotating shaft 4. One end of the conveying dragon 11 passes through the bottom of the conveying cylinder 15 and extends to the outside of the conveying cylinder 15, and the end of the conveying dragon 11 extending outside the conveying cylinder 15 is coaxially fixedly connected to the second pulley 20. The belt 19 is connected between the first pulley 18 and the second pulley 20.

[0041] Working principle: Add materials into the screening cylinder 2 through the feeding port.

[0042] Start the first motor 3, the rotating shaft 4 rotates, the movable sleeve 17 rotates, and the first screen 5 and the second screen 24 rotate synchronously. When the first protrusion 21 rotates around the axis of the rotating shaft 4, when the first protrusion 21 contacts the second protrusion 25, the first protrusion 21 moves upward along the second protrusion 25, the movable sleeve 17 moves upward, and the first screen 5 and the second screen 24 move upward. After the first protrusion 21 moves to the top of the second protrusion 25, under the action of the gravity of the movable sleeve 17, the first screen 5 and the second screen 24, the first protrusion 21 moves downward along the slider 26, and the movable sleeve 17, the first screen 5 and the second screen 24 move downward. Under the action of multiple second protrusions 25, the first protrusion 21 moves up and down reciprocatingly, thereby causing the first screen 5 and the second screen 24 to shake.

[0043] At the same time, under the action of the transmission assembly, the conveying dragon 11 rotates. The material left on the second screen 24 enters the conveying cylinder 15 through the discharge pipe 12, and the conveying dragon 11 conveys the material in the conveying cylinder 15 to the upper end of the conveying cylinder 15, and then enters the screening cylinder 2 again through the feed pipe 13 for screening.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
