Description

Technical Field

[0001] The utility model relates to the technical field of feeders, in particular to a multi-section adjustable spiral weighing feeder. Background Technique

[0002] The conveying efficiency of a spiral feeder is related to the rotational speed of the feeding screw, the structural dimensions of the spiral blades, the friction coefficient between the blades and the material, the friction coefficient between the material and the barrel, etc. When the spiral feeder works, the material in the barrel is pushed by the spiral blades and moves axially forward along the barrel, and finally is pushed out from the discharge port. Due to the gravity of the material itself and the friction force on the barrel, the material does not rotate with the spiral blades, and its working condition is similar to that of a non-rotating nut moving linearly along the screw. In fact, during the conveying process, the movement of the material particles is affected by the inclination angle β of the rotating spiral end face. The material is subjected to both axial thrust and radial thrust on the spiral end face. Therefore, the material does not simply move linearly, but forms a spatial movement with the rotation of the screw.

[0003] The publication number of the comparative patent document is: "CN211725683U A spiral feeder, including: a barrel, a hopper and a feeding screw. The inside of the barrel is divided into a material receiving section and a material conveying section that are connected left and right. The upper end of the material receiving section of the barrel is open to receive the bottom opening of the hopper; the feeding screw has a rotating shaft and spiral blades wound around the rotating shaft. The feeding screw passes through the entire barrel; one end of the material receiving section of the barrel forms an installation opening, and one end of the rotating shaft passes through the installation opening and is connected to the power end of the rotary driving device. The rotary driving device drives the feeding screw to rotate; one end of the material conveying section of the barrel forms a discharge port corresponding to the installation opening, and the spiral blades of the feeding screw extend out of the discharge port. The structure of the utility model is simple, the operation and maintenance are convenient, and it has been widely used in the occasion of conveying materials."

[0028] Please refer to Figures 1-5 , a multi-stage adjustable screw weighing feeder provided by the present invention includes a support frame 1, and also includes a material box 2.

[0029] Further, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it is worth specifically stating that the feeding assembly includes a servo motor 7, which is fixed to one side wall of the material box 2. One end of the feeding pipe 6 is fixed with a bearing seat 8. A transmission shaft 9 is rotatably connected between the material box 2 and the bearing seat 8. One end of the transmission shaft 9 is fixed to the output shaft of the servo motor 7 through a coupling. A spiral blade 10 is tightly sleeved on the outer surface of the transmission shaft 9. A plurality of stirring blades 11 distributed in a circumferential manner are fixed on the outer surface of the transmission shaft 9. The plurality of stirring blades 11 are located inside the material box 2. A plurality of stirring rods 12 arranged in a spiral manner are fixed on the outer surface of the transmission shaft 9. The stirring rods 12 are located on one side of the discharge chute 33. Through the setting of the feeding assembly, materials with relatively high viscosity and compressibility can be conveyed, and the applicable range is relatively wide. Moreover, the conveying effect of the materials can be guaranteed, and the situation of unsmooth material conveyance or even blockage caused by excessive viscosity of the materials can be avoided, and the practicability is relatively strong.

[0030] Further, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it is worth specifically stating that the discharging assembly includes a discharge hopper 13, which is fixed to the outer side wall of the feeding pipe 6. The discharge hopper 13 is located on one side of the discharge chute 33. A hinge seat 14 is fixed to the bottom side wall of the discharge hopper 13. A rotating rod 15 is rotatably connected to one side of the hinge seat 14. A blanking hopper 16 is tightly sleeved on the outer surface of the rotating rod 15. A support rod 17 is rotatably connected to one side wall of the blanking hopper 16; a limiting rod 18, the limiting rod 18 is slidably penetrated through one side wall of the support rod 17.

Compared with the traditional feeder, the discharging effect of this device is better and the flexibility is high.

[0031] Further, as shown in Figure 1 and Figure 4As shown in the figure, it is worth specifically explaining that two symmetrically distributed bearing frames 22 are fixed on the outer surface of the material conveying pipe 6. The bottom side walls of the two bearing frames 22 are jointly fixed with a base a23. A through groove 24 is formed on one side wall of the material conveying pipe 6. A sealing cover plate 25 is rotatably connected inside the through groove 24. A handle 26 is fixed on one side wall of the sealing cover plate 25. Through the setting of the sealing cover plate 25 and the through groove 24, when the feeding in the material conveying pipe 6 is not smooth or even blocked, it is convenient for the staff to clean and maintain the inside of the material conveying pipe 6 from the through groove 24, which has strong flexibility for the staff. And with the setting of the bearing frame 22, the stability of the material conveying pipe 6 can be greatly improved.

[0032] Furthermore, as shown in Figure 1 and Figure 4 it is worth specifically explaining that the bottom side wall of the support frame 1 is fixed with a base b27. The projected area value of the base b27 is greater than the projected area value of the feed bin 2. The bottom surfaces of the base a23 and the base b27 are arranged on the same horizontal plane. Through the setting of the base b27 and the base a23, it can be ensured that the device operates in a relatively stable state.

[0033] Furthermore, as shown in Figure 3 and Figure 4 it is worth specifically explaining that a weighing sensor 28 is arranged on one side of the bin barrel 4, and a solenoid valve 29 is arranged outside the pipeline 5. The weighing sensor 28 is electrically connected to the solenoid valve 29. Through the setting of the weighing sensor 28 and the solenoid valve 29, not only can the materials stored in the feed bin 2 be accurately weighed and recorded, but also it can ensure that the materials fall into the feed bin 2 in time, effectively and accurately controlling the material storage amount for the feeding operation, which has good guarantee.

[0034] Furthermore, as shown in Figure 4 it is worth specifically explaining that a feed pipe 30 communicating with the inside is fixed on the top side wall of the bin barrel 4. The central axis of the bin barrel 4 is collinear with the central axis of the feed bin 2. Through the setting of the feed pipe 30, it is convenient for the staff to connect the feed pipe 30 to feed materials into the bin barrel 4, and the feeding work can be achieved in a dust-free state, thus having good guarantee for the feeding work of the materials.

[0035] Furthermore, as shown in Figure 4 it is worth specifically explaining that an installation groove 31 is formed on one side wall of the feed bin 2, and a transparent plate 32 is fixed on one side of the installation groove 31. Through the setting of the transparent plate 32, it is convenient for the staff to observe the storage condition of the materials in the feed bin 2 in real time, so as to make work feedback in time and facilitate the staff to make operation adjustments.

[0036] Working principle: When feeding operations need to be carried out on materials, first, the materials are input into the silo barrel 4 through the feeding pipe 30. The weighing sensor 28 weighs the materials in the silo barrel 4. When the storage capacity of the materials in the silo barrel 4 exceeds the preset value, a control instruction is sent to the solenoid valve 29, and the solenoid valve 29 is driven to release the blocking effect on the pipeline 5, causing the materials in the silo barrel 4 to fall into the material box 2 through the pipeline 5. Driven by the servo motor 7, the transmission shaft 9 rotates synchronously, driving the stirring blades 11 to rotate synchronously. The stirring blades 11 evenly disperse the materials in the material box 2, thereby driving the spiral blades 10 to rotate synchronously, causing the materials to enter the feeding pipe 6 evenly after being stressed, and the materials are discharged from the discharge chute 33. When adjusting the discharge angle of the materials, by pulling the pull ring 19, the spring 20 is stressed and in a stretched state, causing the limit rod 18 to be separated from the limit hole 21 after being stressed, thus releasing the limit on the support rod 17, and adjusting the hopper 16 to the appropriate position. By loosening the pull ring 19, using the elastic action of the spring 20, the limit rod 18 rebounds and resets after being stressed, causing the limit rod 18 to engage with the limit hole 21, thus achieving the purpose of adjusting the angle of the hopper 16.
