[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes an automatic weighing device for a feeding vessel, including a fixed ring 1, support feet 2, and a sliding groove 3. The support feet 2 are symmetrically fixedly connected to both sides of the fixed ring 1, and the sliding groove 3 is symmetrically provided on both sides of the fixed ring 1. A clamping mechanism is provided inside the sliding groove 3, and an automatic weighing component is symmetrically provided on both sides of the fixed ring 1. The feeding vessel is placed into the inside of the fixed ring 1 from top to bottom. The clamping mechanism applies pressure to both sides of the feeding vessel to clamp it, so that the feeding vessel and the fixed ring 1 are connected as one unit. The support feet 2 support the fixed ring 1, which can increase the support capacity of the fixed ring 1 for the feeding vessel, making the structure more stable when the feeding vessel is feeding. After the material enters the inside of the feeding vessel, the automatic weighing component automatically weighs the material.

[0019] The clamping mechanism includes clamping blocks 4, a bidirectional lead screw 5, and an adjusting nut 6. The clamping blocks 4 are slidably connected inside the sliding groove 3. The bidirectional lead screw 5 is provided on the front of the fixing ring 1. The two ends of the bidirectional lead screw 5 are threadedly connected to the adjacent ends of the two clamping blocks 4, respectively. The adjusting nut 6 is fixedly connected to the middle of the bidirectional lead screw 5. After the feed vessel enters the interior of the fixing ring 1, the wrench is engaged on the outside of the adjusting nut 6. The adjusting nut 6 is connected to the bidirectional lead screw 5 as a whole. By turning the wrench, the bidirectional lead screw 5 is rotated. The two ends of the bidirectional lead screw 5 are threadedly engaged with the ends of the two clamping blocks 4, respectively. The sliding groove 3 can restrict the movement trajectory of the clamping blocks 4. When the bidirectional lead screw 5 rotates, it can drive the two clamping blocks 4 to move linearly back and forth in different directions. When the bidirectional lead screw 5 rotates in the forward direction, it can drive the two clamping blocks 4 to move closer to each other and clamp the feed vessel, thereby connecting the fixing ring 1 and the feed vessel as a whole. The support foot 2 can increase the support capacity of the fixing ring 1 for the feed vessel.

[0020] A connecting plate 10 is fixedly connected to the top of the clamping block 4. The connecting plate 10 has symmetrical connecting holes 15 on both sides. A fixing bolt is threaded into the connecting hole 15. After the clamping block 4 clamps the feed vessel, the connecting hole 15 coincides with the assembly hole inside the feed vessel. The fixing bolt is passed through the connecting hole 15 and screwed into the assembly hole to fix the connecting hole 15 and the feed vessel as one, making the connection between the clamping block 4 and the feed vessel more stable.

[0021] The automatic weighing assembly includes a fixing frame 7, a weighing module 8, and a control module 9. The weighing module 8 has symmetrical fixing holes 14 on both sides. A connecting bolt is inserted into the fixing hole 14. One end of the connecting bolt is threaded to the mounting hole inside the feed vessel. The fixing hole 14 inside the weighing module 8 coincides with the mounting hole inside the feed vessel. The connecting bolt is passed through the fixing hole 14 and screwed into the mounting hole to fix the fixing hole 14 and the feed vessel as one unit.

[0022] The fixed ring 1 is symmetrically fixedly connected to two sides of the fixed frame 7. The top of the fixed frame 7 is equipped with a control module 9, and the top of the control module 9 is equipped with a weighing module 8. The control module 9 is equipped with a weighing sensor. When the material enters the inside of the feeding vessel, the weighing sensor is the core component of the automatic weighing device. It is responsible for converting the weight of the object into an electrical signal. The sensor is usually located below the weighing platform. It senses the weight through deformation, thereby changing its resistance or other electrical characteristics and generating a weak analog signal. The control module 9 is also equipped with a circuit section, which includes analog circuits and digital circuits. The analog circuit is used to amplify the weak signal generated by the weighing sensor, while the digital circuit is responsible for converting the amplified analog signal into a digital signal so that it can be read and processed by a computer or microcontroller. The computer is responsible for processing the digital signal transmitted by the weighing sensor, executing a series of algorithms and calculations to determine the accurate mass of the object. In addition, the control unit is also responsible for controlling other functions of the automatic weighing device, such as tare, calibration, and data output. The computer is equipped with a display module, which is used to display the weighing result. The processing unit transmits the calculated mass of the object to the display module, and the user can read the weighing result through the display screen.

[0023] The fixed frame 7 has a strip groove 11 inside, and a threaded rod 12 passes through the strip groove 11. The top end of the threaded rod 12 is fixedly connected to the bottom of the control module 9, and the bottom end of the threaded rod 12 is threadedly connected to a threaded sleeve 13. During the connection process between the weighing module 8 and the feeding vessel, the bottom end of the threaded rod 12 can be loosened to release the locking state between the fixed frame 7 and the threaded rod 12. At this time, the threaded rod 12 can slide inside the strip groove 11 to adjust the position of the weighing module 8 so that the fixed hole 14 coincides with the mounting hole inside the feeding vessel, which facilitates the connection between the weighing module 8 and the feeding vessel.

[0024] The bottom of the support foot 2 is provided with a pad. The pad is rectangular in structure. A damping block is fixedly connected to the bottom of the pad. The damping block at the bottom of the support foot 2 can increase the friction between the pad and the ground and improve the support capacity of the support foot 2 for the fixed ring 1.

[0025] In this automatic weighing device for the feeding vessel, after the feeding vessel enters the interior of the fixed ring 1, the wrench is engaged on the outside of the adjusting nut 6. The adjusting nut 6 is connected to the double-acting screw 5 as a whole. By turning the wrench, the double-acting screw 5 is rotated. The two ends of the double-acting screw 5 are respectively threaded into one end of the two clamping blocks 4. The sliding groove 3 can restrict the movement trajectory of the clamping blocks 4. When the double-acting screw 5 rotates, it can drive the two clamping blocks 4 to move linearly back and forth in different directions. When the double-acting screw 5 rotates in the forward direction, it can drive the two clamping blocks 4 to move closer to each other and clamp the feeding vessel, thereby connecting the fixed ring 1 and the feeding vessel as a whole. The support foot 2 can increase the support capacity of the fixed ring 1 for the feeding vessel.
