Abstract
Description
Technical Field
[0001] This utility model belongs to the field of loss-in-weight weighing technology, specifically referring to a loss-in-weight weighing system with a back-and-forth swinging feeding mechanism. Background Technology
[0002] In modern industrial production, especially in many processes such as material batching and quantitative feeding, accurate material weighing and feeding control are crucial. Loss-in-weight scales, with their advanced sensing technology and precise weighing system, can monitor subtle changes in the weight of materials in the silo in real time and accurately, ensuring that the weight error of each feeding is controlled within a very small range, and are therefore widely used.
[0003] However, loss-in-weight scales are generally used in conjunction with fixed silo-type feeding equipment. The material feeding process lacks dynamic adjustment capabilities and is prone to problems such as material accumulation and uneven flow, resulting in low feeding accuracy. Utility Model Content
[0004] The technical problem this invention aims to solve is that fixed hopper-type feeding devices lack dynamic adjustment capabilities during the material feeding process, and are prone to low feeding accuracy due to problems such as material accumulation and uneven flow.
[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a loss-in-weight scale with a back-and-forth swinging feeding method, including a loss-in-weight scale body, a support arranged opposite to the scale body, a rotating shaft rotatably provided on the top of the support, a hopper fixed on the rotating shaft, a receiving component provided at the bottom of the support and below the hopper, and a driving component for driving the hopper to swing and feed material on the rotating shaft and the support.
[0006] Preferably, the driving component includes a turntable and a first driving motor. A connecting plate is fixedly connected to the end of the rotating shaft. A sliding groove is provided on the connecting plate. A support plate is provided on the inner top wall of the bracket. The first driving motor is mounted on the support plate. The output end of the first driving motor rotates through the support plate and extends out. The turntable is connected to the output end of the first driving motor. A protruding post is provided at the eccentric part of the turntable. The protruding post is slidably disposed in the sliding groove.
[0007] Preferably, the receiving component includes a hopper and a conveying cylinder, a connecting rod is provided between the inner sidewalls of the two sets of supports, a support frame is provided between the connecting rods, the conveying cylinder is fixed on the support frame, the bottom end of the hopper is connected to the top of the conveying cylinder, the bottom end of the hopper is provided with a discharge port, and the discharge port is located above the hopper.
[0008] Preferably, valves are provided at the bottom of the hopper and at the discharge port.
[0009] Preferably, a spiral conveying paddle is provided between the two inner sidewalls of the conveying cylinder, a second drive motor is provided on the sidewall of the conveying cylinder, the end of the spiral conveying paddle rotates through the conveying cylinder and is connected to the output end of the second drive motor, and a discharge port is provided at the bottom end of the conveying cylinder.
[0010] Preferably, the support frame has a ring in the middle that matches the conveying cylinder, the ring is fixed to the conveying cylinder, and the two ends of the support frame are fixed to the connecting rod.
[0011] The beneficial effects achieved by adopting the above-described structure are as follows:
[0012] 1. By monitoring the material weight change in real time through the loss-in-weight scale itself, the feeding amount can be accurately controlled. Combined with the oscillating feeding action of the hopper, compared with the traditional fixed feeding method, the probability of feeding error caused by material blockage and uneven accumulation is reduced. It can accurately meet the material ratio required by the production process and effectively ensure the stability of product quality.
[0013] 2. The oscillating design of the hopper makes it less likely for materials to clump or bridge during the falling process. Whether it is the dust agglomeration that is prone to occur in powdery materials or the particle bridging phenomenon that may occur in granular materials, it can be effectively improved, ensuring smooth material feeding.

The utility model will be further described in detail below with reference to the accompanying drawings.
[0021] like Figure 1-4 As shown, the present invention proposes a loss-in-weight scale with a back-and-forth swinging feeding mechanism, comprising a loss-in-weight scale body 1, a support 2 arranged opposite to the support 1, a rotating shaft 3 rotatably mounted on the top of the support 2, a hopper 4 fixed on the rotating shaft 3, and a receiving component 5 located at the bottom of the support 2 and below the hopper 4. A driving component 6 is provided on the rotating shaft 3 and the support 2 to drive the hopper 4 to swing and feed material. The hopper 4 is driven to swing and feed material via the driving component 6, and the material is received and transported via the receiving component 5. The loss-in-weight scale body 1 detects changes in material composition.
[0022] like Figure 2-3 As shown, the driving component 6 includes a turntable 7 and a drive motor 8. The end of the rotating shaft 3 is fixedly connected to a connecting plate 9, and the connecting plate 9 is provided with a sliding groove 10. The inner top wall of the bracket 2 is provided with a support plate 11. The drive motor 8 is mounted on the support plate 11. The output end of the drive motor 8 rotates through the support plate 11 and extends out. The turntable 7 is connected to the output end of the drive motor 8. The eccentric part of the turntable 7 is provided with a protruding post 12, which slides in the sliding groove 10. When the drive motor 8 is started, the turntable 7 is driven to rotate. The protruding post 12 on the turntable 7 slides in the sliding groove 10 of the connecting plate 9 to drive the hopper 4 to swing and discharge materials.
[0023] like Figure 4As shown, the receiving component 5 includes a hopper 13 and a conveying cylinder 14. A connecting rod 15 is provided between the inner sidewalls of the two sets of brackets 2, and a support frame 16 is provided between the connecting rods 15. The conveying cylinder 14 is fixed on the support frame 16. A ring 22 matching the conveying cylinder 14 is provided in the middle of the support frame 16. The ring 22 is fixed on the conveying cylinder 14. Both ends of the support frame 16 are fixed on the connecting rods 15. The bottom end of the hopper 13 is connected to the top of the conveying cylinder 14. Valves 18 are provided on the bottom end of the hopper 13 and the discharge port 17. The bottom end of the hopper 4 is provided with a discharge port 17, which is located above the hopper 13. When the hopper 4 swings to discharge material, it is received by the hopper 13 and conveyed out in conjunction with the conveying cylinder 14.
[0024] like Figure 2-3 As shown, a spiral conveying paddle 19 is provided between the two inner side walls of the conveying cylinder 14. A second drive motor 20 is provided on the side wall of the conveying cylinder 14. The end of the spiral conveying paddle 19 rotates through the conveying cylinder 14 and is connected to the output end of the second drive motor 20. A discharge port 21 is provided at the bottom end of the conveying cylinder 14. When the second drive motor 20 is started, the spiral conveying paddle 19 is driven to rotate, and the material in the conveying cylinder 14 is discharged from the discharge port 21.
[0025] In practical use, the material is first loaded into the hopper 4, and the drive motor 8 is started. The output end of the drive motor 8 drives the turntable 7 to rotate. Since the convex post 12 at the eccentric part of the turntable 7 is slidably set in the slide groove 10 of the connecting plate 9, as the turntable 7 rotates, the convex post 12 slides in the slide groove 10, thereby pushing the connecting plate 9, so that the hopper 4, which is fixedly connected to the rotating shaft 3, swings back and forth around the rotating shaft 3. At this time, the discharge port 17 at the bottom of the hopper 4 is located above the hopper 13, and the material falls from the discharge port 17 into the hopper 13. The valve 1 is set at the bottom of the hopper 13 and on the discharge port 17. 8 can control the flow of materials as needed. For example, valve 18 can be closed during initial loading, equipment debugging, or a brief stop of feeding to prevent material leakage. After the material falls into the hopper 13, drive motor 20 is started. Drive motor 20 drives the screw conveyor 19 to rotate in the conveying cylinder 14. Under the push of the screw conveyor 19, the material is stably discharged from the discharge port 21 at the bottom of the conveying cylinder 14 and enters the subsequent production process. Throughout the process, the loss-in-weight scale body 1 monitors the change in the weight of the material in the hopper 4 in real time. Once the preset feeding amount is reached, the swing feeding stops.
[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
