[0020] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection, an electrical connection, or a communication connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0022] A multi-stage sorting scale capable of setting the expected weight of each stage, comprising a weighing part and a sorting part, wherein the weighing part comprises a weighing bracket 1, an electric drive conveyor belt 2 is arranged on the weighing bracket 1, a weighing sensor 4 is arranged under the electric drive conveyor belt 2, a control box 5 is arranged on the side of the electric drive conveyor belt 2, and an HMI human-machine control panel 6 is arranged on the control box 5;

[0023] The sorting part is connected to the traveling direction of the electric-driven conveyor belt 2 , and includes a sorting bracket 7 , on which a chain plate conveyor belt 8 is installed. Sorting devices are installed on both sides of the chain plate conveyor belt 8 , and the sorting devices are electrically connected to the control box 5 .

[0024] During specific implementation, a weighing part universal support foot 3 is respectively installed at the four corners below the weighing bracket 1, and a sorting part universal support foot 15 is respectively installed at the four corners below the sorting bracket 7. The sorting device includes a hopper 9 installed on the side of the chain conveyor belt 8, and a swing arm device 10 is provided at the connection between the hopper 9 and the chain conveyor belt 8. An outlet flap 11 is provided at the bottom of the hopper 9, and a flap cylinder 12 is connected between the outlet flap 11 and the hopper 9. A reset button 13 and an audible and visual alarm 14 that cooperate with the outlet flap 11 are installed on the hopper 9. The chain conveyor belt 8, the reset button 13, the audible and visual alarm 14, the flap cylinder 12 and the swing arm device 10 are all electrically connected to the control box 5.

[0025] The advantage of this technical solution is that a weighing part and a sorting part are set up. The weighing part collects the product weight through the weighing sensor 4, and controls the sorting part through data processing and signal transmission, thereby realizing the automatic control of weighing and sorting operations. The HMI human-machine control panel 6 is used to complete the entry of preset grading weight data and the control box 5 is used to realize the electrical control of the chain conveyor belt 8, the reset button 13, the flap cylinder 12 and the swing arm device 10, which can complete the automatic sorting of materials, reduce labor costs, and improve production efficiency.

[0026] In specific operation, when this equipment is used to sort a certain type of product, the weight range and expected cumulative weight of each level can be set through the HMI human-machine control panel 6. After starting weighing through the HMI human-machine control panel 6, the front-end production line sends the product to the weighing part, and the weighing sensor 4 in the weighing part determines the product weight, and sends the judgment signal and the product weight to the controller and PLC in the control box 5. The signal of this product is given to the sorting part through the controller and PLC, and the weight is accumulated. For example, the HMI human-machine control panel 6 is used to set the sorting weight range to 0g to 100g, the expected weight is 500g, and a 50g product is sent to the front end. When this product flows into the weighing part, the weighing sensor 4 collects Weight, after AD conversion, the weight data is transmitted to the controller and PLC. The controller determines that this product belongs to sorting one and sends the weight to the PLC. When the product flows into the sorting part and moves to the sorting one position on the chain conveyor belt 8, the swing arm device 10 of sorting one works, and the product flows into the prepared material frame through the hopper 9 of sorting one. This cycle continues. When the cumulative weight of sorting one is greater than or equal to 500g, the outlet flap 11 on the hopper 9 of sorting one is closed under the drive of the flap cylinder 12, and this level of work is stopped. At the same time, the sound and light alarm lights remind the staff to change the material frame and other processing. After the processing is completed, press the reset button 13, the sound and light alarm stops, this level restarts to work, and restarts the cumulative weight.

[0027] In the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may mean that the first feature is in direct contact with the second feature, or the first feature and the second feature are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example" or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.
