[0036] As Figures 1 - 4 shown, a dolomite powder discharging and automatic conveying device provided in this embodiment includes:

[0037] Weighing platform 7; The weighing platform 7 can be a stainless steel electronic weighbridge or an electronic weighbridge with an RS232 / 485 interface connected to a computer. Its principle is as follows: When the object to be weighed (material container) is placed on the placement plate 5, its weight is transmitted through the placement plate 5 to the weighing sensor. The sensor then generates a force - electricity effect, converting the weight of the object into an electrical signal (such as voltage or current, etc.) that has a certain functional relationship (generally a proportional relationship) with the weight of the object to be weighed. This signal is amplified by an amplifier circuit, filtered, and then converted by an analog - to - digital (A / D) converter. The digital signal is then sent to the CPU of the microprocessor for processing. The CPU continuously scans the keyboard and various function switches, makes necessary judgments and analyses based on the content input from the keyboard and the states of various function switches, and controls various operations through the software of the instrument. The operation results are sent to the memory. When display is required, the CPU issues an instruction to read from the memory and send it to the display for display, or send it to the printer for printing. Generally, signal amplification, filtering, A / D conversion, and various signal operation processes are completed in the instrument.

[0038] Placement plate 5, the placement plate 5 is slidably connected to the first conveying component 1 and the second conveying component 2 respectively. The placement plate 5 is used for placing the material container; the placement plate 5 is a stainless steel flat plate.

[0039] First conveying component 1, the first conveying component 1 is arranged on the weighing platform 7; the first conveying component 1 can be an existing roller conveyor line, which can be driven by a driving motor 10 or by gravity inertia.

[0040] Second conveying component 2, the second conveying component 2 is arranged downstream of the first conveying component 1 in the conveying direction; the second conveying component 2 can be an existing roller conveyor line, which can be driven by a motor or by gravity inertia.

[0041] First blocking component 3, the first blocking component 3 is arranged between the first conveying component 1 and the second conveying component 2. The first blocking component 3 is used to block the movement of the placement plate 5 from the first conveying component 1 to the second conveying component 2; the first blocking component 3 can be a rod - shaped structure.

[0042] Second blocking component 4, the second blocking component 4 is arranged at one end far from the first conveying component 1. The second blocking component 4 is used to block the placement plate 5 from detaching from the second conveying component 2. The second blocking component 4 can be a rod - shaped structure.

[0043] The device further includes a controller which is used to receive the weight detected by the weighing platform 7. By presetting the weight of each bag of dolomite powder, when the detected weighing weight reaches the preset weight, the controller sends a signal to the valve of the discharging machine to control the valve to close. Then, it controls the clamping structure of the discharging machine to release the clamped material bag. Then, the controller controls the cylinder 33 of the first blocking component 3 to drive the first blocking rod to move, releasing the placing plate 5 blocked by the first blocking rod, so that the placing plate 5 can move towards the first conveying component 1. After the material bag is lifted by a forklift from the second conveying component 2, the placing plate 5 is manually pushed back onto the first roller 12 of the first conveying component 1, and the controller controls the cylinder 33 to drive the first blocking rod to block the placing plate 5, completing the entire control process. The controller is an existing PLC controller.

[0044] The weighing platform 7 includes a display value module, a force transmission and conversion module, a weighing sensor, and a weighing table. The display value module is connected to the force transmission and conversion module through a data cable, and the weighing sensor is connected to the force transmission and conversion module through a data cable; the first conveying component 1 is arranged on the weighing table; the weighing sensor is arranged on the weighing table to detect the weight of the weighing table, the first conveying component 1 arranged on the weighing table, the placing plate 5, and the material container. The display value module, the force transmission and conversion module, the weighing sensor, and the weighing table are all components of an existing electronic scale. The force transmission and conversion module and the weighing table are the load-bearing and force transmission reset system of the electronic scale: it is the mechanical and force transmission reset system between the object to be weighed and the conversion element, also known as the scale body of the electronic scale, generally including a carrier for receiving the load of the object to be weighed, a scale bridge structure, hanging connection components, and a limit and damping mechanism, etc. The display value module is the electronic circuit (including amplifiers, analog-to-digital conversion, current source or voltage source, regulators, compensation elements, protection circuits, etc.) for processing the signals of the weighing sensor of the electronic scale and the indicating components (such as displays, printers, data transmission, and storage devices, etc.). This part is customarily called the load measurement device or secondary instrument. In a digital measurement circuit, it usually includes links such as pre-amplification, filtering, operation, conversion, counting, storage, control, and driving display. When in use, first place the first conveying component 1 and the placing plate 5 on the weighing table, and then set the weighing display value to zero.

[0045] The first conveying component 1 includes a first bracket 11 and first rollers 12. The first bracket 11 is arranged on the weighing platform 7.

The assembly manner of the second rollers 22 and the second bracket 21 is consistent with the structure of the existing roller assembly line, so it will not be elaborated here.

[0047] The first blocking component 3 includes a cylinder 33 and a blocking rod 32. The cylinder 33 is installed outside the area between the first conveying component 1 and the second conveying component 2. The blocking rod 32 is connected to the movable end of the cylinder 33. The cylinder 33 is used to drive the blocking rod 32 to extend into the area between the first conveying component 1 and the second conveying component 2 to block the placing plate 5.

[0048] In some embodiments, the first blocking component 3 includes a rotating motor 8 and a blocking plate 9. The rotating motor 8 is fixed outside the area between the first conveying component 1 and the second conveying component 2. The blocking plate 9 is fixedly connected to the output shaft of the rotating motor 8.

[0049] The second blocking component 4 includes a second blocking rod, and the second blocking rod is arranged at one end far from the first conveying component 1.

[0050] Guardrails are provided on both sides of the second bracket 21. By providing the guardrails, it is avoided that the material containers fall from both sides of the second bracket 21.

[0051] The first bracket 11 is inclined, and the end of the first bracket 11 far from the second bracket 21 is higher than the end close to the second bracket 21.

The slide rail 31 is a groove structure with one end of the groove open, facilitating the horizontal rod to extend out of the groove to be connected to the air cylinder 33. The horizontal rod slides within the groove, and the placement plate 5 is blocked by the vertical rod to prevent the placement plate 5 from moving from the first roller 12 to the second roller 22.

[0054] The device provided in this embodiment weighs the dolomite powder contained in the material container by using the weighing platform 7. When the weight of the material container reaches the preset weight, a signal is sent to the controller to control the valve of the unloader to close, releasing the clamping of the unloader on the material container. The controller controls the first blocking assembly 3 to release the block on the placement plate 5. The first conveying assembly 1 conveys the placement plate 5 to the second conveying assembly 2, and the second conveying assembly 2 continues to convey the placement plate 5 to the end. Then, the placement plate 5 is blocked by the second blocking assembly 4, making the material container relatively fixed. The handling worker manipulates the forklift to lift the material container and then transports it to the corresponding stacking position, completing the process of unloading, bagging, and transporting the dolomite powder. For the entire process, only manual operation is required to dock the material container with the discharge port of the unloader and for the transport worker to manipulate the forklift to lift and transport the material container. The rest of the steps do not require manual operation, with high automation, convenient handling, and high handling efficiency.

[0055] The material container in the above embodiment is a material bag.
