[0025] Please combine them together Figures 1 to 3 The weighing component provided by this utility model will now be described. The weighing component is used in a weighing device.

[0026] The weighing assembly includes: a weighing hopper 1, a discharge valve 2, a power element 3, and a lever 4. The weighing hopper 1 has a discharge port 11. The discharge valve 2 is rotatably connected to the weighing hopper 1 and has a first baffle 21 and a second baffle 22. The power element 3 is connected to the lever 4 for transmission and is used to drive the lever 4 to rotate. The power element 3 drives the lever 4 to rotate, the lever 4 abuts against and drives the first baffle 21 to move, and the first baffle 21 drives the discharge valve 2 to rotate to close the discharge port 11. The power element 3 also drives the lever 4 to rotate. The lever 4 abuts against and drives the second baffle 22 to move. The second baffle 22 drives the discharge valve 2 to rotate to open the discharge port 11. Specifically, the discharge valve 2 is an arc valve.

[0027] It is understood that the weighing hopper 1 of the weighing assembly has a discharge port 11, and the discharge valve 2 is rotatably connected to the weighing hopper 1. The discharge valve 2 has a first baffle 21 and a second baffle 22. The power element 3 is driven by the lever 4 and is used to drive the lever 4 to rotate. The power element 3 drives the lever 4 to rotate, and the lever 4 abuts against and drives the first baffle 21 to move. The first baffle 21 drives the discharge valve 2 to rotate to close the discharge port 11. The power element 3 also drives the lever 4 to rotate, and the lever 4 abuts against and drives the second baffle 22 to move. The second baffle 22 drives the discharge valve 2 to rotate to open the discharge port 11. In this way, the discharge valve 2 can rotate in an arc to open or close the discharge port 11, resulting in a smaller travel distance and less space occupation. Furthermore, the arc rotation of the discharge valve 2 ensures that any residual material on the discharge valve 2 can fall off, without affecting the accuracy of the next weighing.

[0028] It should be added that the driving element can be a motor.

[0029] It should be noted that the power element 3 drives the lever 4 to rotate, the lever 4 abuts against and drives the first baffle 21 to move, the first baffle 21 drives the discharge valve 2 to rotate to close the discharge port 11; the power element 3 drives the lever 4 to rotate in the opposite direction, the lever 4 abuts against and drives the second baffle 22 to move, the second baffle 22 drives the discharge valve 2 to rotate in the opposite direction to open the discharge port 11.

[0030] In this embodiment, the weighing assembly further includes a limiting block 5, which is rotatably connected to the weighing hopper 1 and is used to lock and unlock the discharge valve 2. Thus, the discharge valve 2 can be locked and unlocked, thereby enabling the discharge valve 2 to stably close the discharge port 11.

[0031] When lever 4 abuts against and drives the first baffle 21 to move, and the first baffle 21 drives the discharge valve 2 to rotate to close the discharge port 11, lever 4 abuts against and drives the limit block 5 to rotate, and the limit block 5 locks the discharge valve 2. Specifically, when lever 4 abuts against and drives the first baffle 21 to move, and the first baffle 21 drives the discharge valve 2 to rotate to close the discharge port 11, at this time, lever 4 abuts against and drives the limit block 5 to rotate, and the limit block 5 locks the discharge valve 2.

[0032] The power element 3 also drives the lever 4 to rotate. The lever 4 abuts against and drives the second baffle 22 to move. During the process of the second baffle 22 driving the discharge valve 2 to rotate and open the discharge port 11, the lever 4 abuts against and drives the limit block 5 to rotate, and the limit block 5 unlocks the discharge valve 2. Specifically, the power element 3 drives the lever 4 to rotate in the reverse direction. The lever 4 first abuts against and drives the limit block 5 to rotate, and the limit block 5 unlocks the discharge valve 2. Then, the power element 3 continues to drive the lever 4 to rotate in the reverse direction. The lever 4 abuts against and drives the second baffle 22 to move, and the second baffle 22 drives the discharge valve 2 to rotate and open the discharge port 11.

[0033] Furthermore, the limiting block 5 has a limiting point 51, the discharge valve 2 has a locking groove 23, the limiting block 5 has a locking end 52 and an unlocking end 53, the power element 3 drives the lever 4 to abut the locking end 52, the limiting block 5 rotates, and the limiting point 51 is limited within the locking groove 23, the power element 3 drives the lever 4 to abut the unlocking end 53, the limiting block 5 rotates, and the limiting point 51 disengages from the locking groove 23. Specifically, the lever 4 abuts against and drives the first baffle 21 to move, the first baffle 21 drives the discharge valve 2 to rotate to close the discharge port 11, at this time, the lever 4 abuts against the locking end 52 and drives the limiting block 5 to rotate, the limiting point 51 is limited within the locking groove 23 to lock the discharge valve 2. The power element 3 drives the lever 4 to rotate in the reverse direction. The lever 4 first abuts against the unlocking end 53 and drives the limit block 5 to rotate. The limit point 51 disengages from the locking groove 23 to unlock the discharge valve 2. Then the power element 3 continues to drive the lever 4 to rotate in the reverse direction. The lever 4 abuts against and drives the second baffle 22 to move. The second baffle 22 drives the discharge valve 2 to rotate to open the discharge port 11.

[0034] Furthermore, the locking end 52 has a closing arc surface, the unlocking end 53 has an opening arc surface, and the lever 4 has an unlocking arc surface 41. The power element 3 drives the lever 4 to abut against the closing arc surface, causing the limit block 5 to rotate and the limit point 51 to be limited within the locking groove 23. The power element 3 drives the lever 4, causing the unlocking arc surface 41 to abut against the opening arc surface, causing the limit block 5 to rotate and the limit point 51 to disengage from the locking groove 23. By setting the closing arc surface, the lever 4 can more easily drive the limit block 5 to rotate. By setting the opening arc surface, the unlocking arc surface 41 can more easily drive the limit block 5 to rotate.

[0035] Specifically, lever 4 abuts against and drives the first baffle 21 to move. The first baffle 21 drives the discharge valve 2 to rotate to close the discharge port 11. At this time, lever 4 abuts against the closing arc surface on the locking end 52 and drives the limit block 5 to rotate. The limit point 51 is limited in the locking groove 23 to lock the discharge valve 2. Power element 3 drives lever 4 to rotate in the opposite direction. The unlocking arc surface 41 of lever 4 first abuts against the opening arc surface of unlocking end 53 and drives the limit block 5 to rotate. The limit point 51 disengages from the locking groove 23 to unlock the discharge valve 2. Then, power element 3 continues to drive lever 4 to rotate in the opposite direction. Lever 4 abuts against and drives the second baffle 22 to move. The second baffle 22 drives the discharge valve 2 to rotate to open the discharge port 11.

[0036] Furthermore, the lever 4 also has a retaining arc surface 42, which abuts against the opening arc surface to keep the limiting point 51 disengaged from the locking groove 23. By setting the retaining arc surface 42, the power element 3 drives the lever 4 to rotate in the reverse direction. The unlocking arc surface 41 of the lever 4 first abuts against the opening arc surface of the unlocking end 53 and drives the limiting block 5 to rotate. The limiting point 51 disengages from the locking groove 23 to unlock the discharge valve 2. Then, the power element 3 continues to drive the lever 4 to rotate in the reverse direction. At this time, the retaining arc surface 42 always abuts against the opening arc surface, thereby keeping the limiting point 51 disengaged from the locking groove 23. The lever 4 abuts against and drives the second baffle 22 to move. The second baffle 22 drives the discharge valve 2 to rotate to open the discharge port 11.

[0037] Furthermore, the lever 4 includes a body 43 and a dial head 44 connected to the body 43. The dial head 44 has an unlocking arc surface 41 and a retaining arc surface 42. The body 43 and the dial head 44 are integrally formed. In this way, the lever 4 will not interfere when it drives the limit block 5 to lock and unlock the discharge valve 2.

[0038] Furthermore, the weighing assembly also includes a shaft 6, through which the power element 3 is fixed to the lever 4. This arrangement ensures that the power element 3 is far from other components, preventing any impact on weighing accuracy.

[0039] In one embodiment, such as Figure 1 As shown, the weighing assembly also includes a sensor module 7. The weighing hopper 1 is detachably connected to the sensor module 7, which is used to weigh the material in the weighing hopper 1. The weighing hopper 1 is detachable, allowing it to be cleaned periodically. The sensor module 7 weighs the material in the weighing hopper 1 until it reaches a preset weight.

[0040] The weighing assembly also includes a hook 8 and a hanging plate 9. The hook 8 is fixed to the weighing hopper 1, and the hanging plate 9 is fixed to the sensor module 7. The hook 8 is hung on the hanging plate 9. This allows the weighing hopper 1 to be disassembled.

[0041] The sensor module 7 includes a load cell 71, a mounting plate 72, and a bracket 73. A hanging plate 9 is fixed to the mounting plate 72 via the load cell 71, and the mounting plate 72 is fixed to the bracket 73. The load cell 71 is fixed to the mounting plate 72 and also to the hanging plate 9, thus enabling weighing of the weighing hopper 1. The load cell 71 is fixed to the bracket 73 via the mounting plate 72, allowing for its secure installation.
