Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-5 This utility model provides a technical solution: an automatic feeding device for a weighing system, including a hopper 1 and a feeding rack 17. The surface of the hopper 1 is fixedly connected to a first motor 2, and the first motor 2 is fixedly connected to a rotating shaft 3. The rotating shaft 3 is rotatably connected to a fixed block 4, and the fixed block 4 is fixedly connected to the inside of the hopper 1. The rotating shaft 3 is connected to a moving plate 10 via a reciprocating vibration mechanism. The reciprocating vibration mechanism includes the rotating shaft 3, the fixed block 4, a cam 5, a roller 6, a fixed plate 7, a push rod 8, a spring 9, and a moving plate 10. The rotating shaft 3 is connected to the cam 5, and the surface of the cam 5 contacts the roller 6. The roller 6 is connected to the fixed plate 7, and the fixed plate 7 is fixedly connected to the push rod 8. The push rod 8 slides against the fixed block 4. The material is connected to the top rod 8, and a spring 9 is provided on the surface of the top rod 8. The top end of the top rod 8 is fixedly connected to the bottom of the moving plate 10. The reciprocating vibration mechanism is symmetrically arranged about the center of the hopper 1, and the reciprocating vibration mechanism is connected to both ends of the bottom of the moving plate 10. The moving plate 10 has an arc inside, and a screen plate 11 is provided inside the moving plate 10. The bottom of the hopper 1 is connected to the conveying pipe 12, and the top of the conveying pipe 12 is fixedly connected to the second motor 13. The second motor 13 is connected to the auger rod 14. A heating pipe 15 is provided inside the conveying pipe 12, and a vent hole 16 is provided on the upper surface of the conveying pipe 12. The heating pipe 15 and the vent hole 16 are arranged in an array about the inside of the conveying pipe 12, and the conveying pipe 12 is made of a high heat-resistant material.
[0020] In use, materials are fed into the silo 1 through the feed inlet above the silo 1 for storage. When the material enters, it is screened through the internal screen plate 11. During the screening process, the rotating shaft 3 is driven by the first motor 2 on both sides. The rotating shaft 3 drives the cam 5 to rotate. When the protrusion of the cam 5 contacts the roller 6, the cam 5 pushes the roller 6. Simultaneously, the roller 6 moves the fixed plate 7, causing the fixed plate 7 to move the upper push rod 8. The push rod 8 slides inside the fixed block 4. At the same time, the spring 9 on the surface of the push rod 8 and the inner wall of the fixed block 4 contract after being compressed, causing the push rod 8 to push the upper moving plate 10. The moving plate 10 then drives the internal screen plate 11 to move up and down. Due to the continuous rotation of the cam 5, when the protrusion of the cam 5 separates from the roller 6... Spring 9 drives top rod 8, roller 6 and fixed plate 7 to reset, causing the upper moving plate 10 to descend. The continuous rotation of cam 5 causes the upper moving plate 10 to move up and down repeatedly, causing the material above screen plate 11 to vibrate. The vibration breaks up the clumps inside the material. When feeding the material into the symmetrical metering system, the second motor 13 is started to drive the auger rod 14 to rotate. The rotation of the auger rod 14 conveys the material from the top of the hopper 1 to the bottom forward. At the same time, the auger rod 14 can stir the material. At the same time, the heating pipe 15 inside the conveying pipe 12 is started to heat the material inside the conveying pipe 12 and dry the material. During the drying process, a large amount of moisture is generated and discharged through the vent 16 above to prevent moisture from accumulating inside and causing the material to become damp again.
[0021] The feeding rack 17 is equipped with a feeding mechanism, which includes the feeding rack 17, a third motor 18, a drive roller 19, a feeding belt 20, and baffles 21. The feeding rack 17 and the third motor 18 are fixedly connected, and the third motor 18 is connected to the drive roller 19, and the drive roller 19 is connected to the feeding belt 20. Baffles 21 are provided on the surface of the feeding belt 20, and the baffles 21 are arranged in an array about the surface of the feeding belt 20. An inclined guide plate 22 is provided at the front end of the feeding rack 17.
[0022] At this time, the material discharged through the conveying pipe 12 enters the surface of the feeding belt 20 inside the feeding rack 17. The third motor 18 is started to drive the drive roller 19 to rotate. After the drive roller 19 drives the feeding belt 20 to rotate, the feeding belt 20, together with the multiple baffles 21 on the surface, lifts the material to the top and then enters the weighing system through the guide plate 22 for weighing.
[0023] Working principle: When using the automatic feeding device for the weighing system, the material is fed into the hopper 1 through the feed inlet above the hopper 1 for storage. The material is then screened through the internal sieve plate 11. During the screening process, the rotating shaft 3 is driven to rotate by the first motor 2 on both sides. The rotating shaft 3 drives the cam 5 to rotate. When the protrusion of the cam 5 contacts the roller 6, the cam 5 pushes the roller 6, which in turn moves the fixed plate 7, causing the fixed plate 7 to move the upper push rod 8. This causes the push rod 8 to slide inside the fixed block 4. Simultaneously, the spring 9 on the surface of the push rod 8 and the inner wall of the fixed block 4 contract after being compressed, causing the push rod 8 to push the upper movable plate 10. At this time, the movable plate 10 drives the internal screen plate 11 to move up and down. Simultaneously, due to the continuous rotation of the cam 5, when the protrusion of the cam 5 separates from the roller 6, the spring 9 drives the push rod 8, roller 6, and fixed plate 7 to reset, causing the upper movable plate 10 to descend. The continuous rotation of the cam 5 causes the upper movable plate 10 to reciprocate up and down, causing the screen plate 11 to... The material is vibrated, breaking up any clumps inside. During feeding into the symmetrical feeding system, the second motor 13 is activated, driving the auger 14 to rotate. The rotation of the auger 14 conveys the material from the top of the hopper 1 forward. Simultaneously, the auger 14 agitates the material. At the same time, the heating pipe 15 inside the conveying pipe 12 is activated to heat and dry the material. During the drying process, a large amount of moisture is generated and discharged through the vent 16 at the top. Moisture buildup inside causes secondary dampness in the material. At this time, the material discharged through the conveying pipe 12 enters the surface of the feeding belt 20 inside the loading rack 17. The third motor 18 is started to drive the drive roller 19 to rotate. After the drive roller 19 drives the feeding belt 20 to rotate, the feeding belt 20, in conjunction with multiple baffles 21 on its surface, lifts the material to the top and then enters the weighing system through the guide plate 22 for weighing, thus completing a series of operations. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
