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.

[0023] like Figures 1 to 5 As shown, this utility model provides an automatic weighing device for precise weighing, including a workbench 1. A first weighing scale 11 is fixedly installed on the top surface of the workbench 1, a first storage box 16 is fixedly installed on the bottom surface of the workbench 1, a second weighing scale 19 is fixedly installed on the bottom surface of the first storage box 16, a second storage box 17 is fixedly installed on one side of the first storage box 16 and is fixedly connected to the workbench 1, a control box 2 is fixedly installed on the top surface of the workbench 1, an electric telescopic device 4 is fixedly installed inside the control box 2, a fixing frame 5 is fixedly installed at the end of the main shaft of the electric telescopic device 4, a cylinder 6 is fixedly installed inside the fixing frame 5, a connecting piece 7 is fixedly installed at the end of the main shaft of the cylinder 6, and a clamp 8 is fixedly installed on the other side of the connecting piece 7. The rotating device is equipped with a connecting shaft 10. A weight limit is set via the control box 2, and then the first weighing scale 11 weighs the objects to be weighed. Objects exceeding the weight limit are sent to the first storage box 16, while those below the limit are sent to the second storage box 17. A second weighing scale 19 is installed at the bottom of the first and second storage boxes 16 and 17. The control box 2 records the total weight weighed by the first weighing scale 11 and the total weight weighed by the second weighing scale 19. By weighing and recording the objects using multiple weighing scales, the accuracy of the weighing values ​​can be verified through calculation. An object sorting function is also added. The weight of the objects is calculated by the weighing scales, and then they are put into different storage boxes to complete the object sorting.

[0024] Specifically, a display screen 3 is fixedly installed on the outside of the control box 2. The surface of the display screen 3 will display the total weight of each weighing scale. The total weight displayed on the display screen 3 makes it convenient for staff to perform calculations.

[0025] Furthermore, a spring 9 is fixedly installed on the inner side of the clamp 8, and a sensor is installed on the outer side of the clamp 8. Under the action of the spring 9, the clamp 8 is in a closed device. When the sensor detects the object to be weighed, the cylinder 6 will start, thereby pulling the clamp 8 to open and clamp the object to be weighed.

[0026] Furthermore, the top surface of the first storage box 16 is rotatably provided with a long shaft 21, and the outer side of the long shaft 21 is rotatably provided with a closing door 18. When the closing door 18 is closed, it forms a protective cover to protect the objects stored inside.

[0027] It is worth noting that a long shaft 21 is fixedly installed on the outer side of the long shaft 21, and one end of the torsion spring 20 is in contact with the closed door 18, and the other end is in contact with the workbench 1. When the weighed object pushes open the closed door 18, the torsion spring 20 provides a reaction force to close the closed door 18.

[0028] It is worth noting that a motor 12 is fixedly installed on the bottom surface of the workbench 1, and a rotating shaft 13 is fixedly installed at the end of the main shaft of the motor 12. The motor 12 drives the rotating shaft 13 to rotate, and the motor 12 is the power source.

[0029] It is worth mentioning that a transmission wheel 14 is rotatably mounted on the outer side of the rotating shaft 13, and a conveyor belt 15 is rotatably mounted on the outer side of the transmission wheel 14. The conveyor belt 15 is used to transport the object to be weighed onto the first weighing scale 11 for weighing.

[0030] Among them, the electric telescopic device 4, cylinder 5, and motor 12 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail; the "front, rear, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0031] Working principle and process:

[0032] Before using an automatic weighing device for precise weighing, firstly, the weight limit is set via the control box 2 on the top surface of the workbench 1. Then, the motor 12 drives the rotating shaft 13 to rotate, and simultaneously, the transmission wheel 14 is driven by the rotating shaft 13. When the transmission wheel 14 rotates, it drives the conveyor belt 15 to start rotating. The conveyor belt 15 transports the object to be weighed to the top surface of the first weighing scale 11. The surface of the first weighing scale 11 is set with a certain inclination. When the object to be weighed is transported to the top surface of the first weighing scale 11, it will slowly... The object slides towards the center of the first weighing scale 11, which then weighs the object. After weighing, the electric telescopic device 4 moves the fixed frame 5. When it moves to the object, the clamp 8 is closed under the action of the spring 9. Therefore, when the cylinder 6 pulls the connecting piece 7, the connecting piece 7 will pull the two sides of the clamp 8, causing the clamp 8 to open and clamp the object. The connecting shaft 10 connects the clamps 8 on both sides. Objects exceeding the red line will be sent to the first storage box. Inside storage box 16, items not exceeding the limit are sent to the second storage box 17. When the weighed object reaches the top of storage box 16, clamp 8 releases it, causing it to fall onto the top of the closed door 18. Under its own weight, the object pushes open the closed door 18 and falls into the interior of storage box 16. Then, the closed door 18 closes again under the action of torsion spring 20. The long shaft 21 is used to install the torsion spring 20. A second weighing scale 19 is installed at the bottom of both storage box 16 and storage box 17. The weighing box 2 records the total weight weighed by the first weighing scale 11 and the total weight weighed by the second weighing scale 19, and then displays them on the display screen 3. Finally, the two numbers are added or subtracted to determine whether the weighing is accurate. This utility model can weigh objects using multiple weighing scales, record the weights, and then verify the accuracy of the weighing values ​​through calculation. It also adds an object sorting function, which calculates the weight of the objects using the weighing scales and then puts them into different storage boxes to complete the sorting of objects.
