[0031] As the first embodiment of the present invention, by setting the batching component 100, cooperating with the material receiving component 20 and the transportation component 300, it is possible to mix and barrel a variety of alloy materials according to different qualities and proportions within a specified time to meet the process requirements. The device can automatically mix twelve alloy materials according to a previously given proportion according to customer needs, replacing complete manual mixing, with high efficiency and low labor intensity.

[0032] See also Figures 1 to 7The feeder 130 includes a feeding electric vibrator 131 and a feeding trough 132. A feeding electric vibrator 131 is installed on the left and right sides of the rear end of the feeding trough 132. The feeding trough 132 is a dustpan-shaped structure. The setting of the feeding trough 132 facilitates the vibration feeding of materials into the quantitative bucket 120.

[0033] The quantitative bucket 120 includes a cylindrical bucket, a supporting frame, a weighing sensor, a cylinder, a transmission rod and a flap. A flap is rotatably installed on the lower side of the cylindrical bucket through the transmission rod, and the diameter of the flap matches the inner diameter of the cylindrical bucket.

[0039] As a second embodiment of the present invention, based on the above-mentioned first embodiment, by setting a batching component 100, coordinating a material receiving component 200 and a transport component 300, in actual use, twelve different alloys are mixed in different proportions, iron and praseodymium and neodymium account for a larger proportion, iron and praseodymium and neodymium are divided into a group, named iron and praseodymium and neodymium batching system; except iron and praseodymium and neodymium, the remaining ten alloys account for a smaller proportion, and these ten alloys are divided into a group, named ten alloy batching system, if it is necessary to feed twelve kinds of alloy materials, the mass proportion of each material is different, if the mass exceeds 200k g, batching is performed in multiple times, in the order of 200(+200)+n. The batching process for a material mass of 200 kg is called a rough batching process, and the batching process for a material mass of less than 200 kg is called a fine batching process (the entire system equipment consists of a batching component 100, a track 400, a transport component 300, a material receiving component 200, an operating platform, and an intelligent monitoring system. The control of the entire system is centralized on the main console. To facilitate operation and maintenance by staff, an escalator is installed next to the entire silo platform. The equipment rack, main console, escalator, operating platform, and intelligent monitoring system are not shown in the figure);

[0040] For the precise batching process, first, the external PLC transmits the fast feeding frequency data to the frequency converter, and the frequency converter controls the feeder 130 to start at high speed. This is the fast feeding stage. When the real-time weighing data reaches the set value 1 (80% of the preset material weight), it pauses for 5 seconds to wait for the value to stabilize. The PLC reduces the feeding frequency and writes it to the frequency converter. The frequency converter controls the feeder 130 to start at low speed. This is the slow feeding stage. When the real-time weighing data reaches the set value 2 (99% of the preset material weight), it pauses for 5 seconds to wait for the value to stabilize. The feeder 130 is turned off and a manual feeding prompt is given. The remaining material is manually replenished to ensure the accuracy of the material weight (see the attached manual for details). Figure 5 ).

[0041] For the roughing process, the corresponding port of PLC controls the corresponding feeder 130 to start at high speed. When the real-time weighing data reaches the set value 2 (99% of the preset material weight), it pauses for 5 seconds to wait for the value to stabilize, and then turns off the feeder 130, prompting manual feeding. The remaining materials are manually added to ensure the accuracy of the material weight (see the attached manual for details). Figure 6 );

[0042] After manual feeding is completed and the confirmation button is pressed, the PLC needs to determine whether the weighing value at this time is equal to the formula value entered at the beginning. If it is not equal, it needs to prompt the manual operation again. If it is equal, it waits for the next process.

[0043] The structure of the batching component 100 mainly includes a feeder 130, a quantitative hopper 120, a storage bin 140, a lower hopper 110, etc. After the batching starts, the PLC determines whether to let the feeding electric vibrator 131 feed according to the value of the weighing sensor on the quantitative hopper 120. If it does not reach 80% of the target weighing value, the PLC controls the frequency converter to control the feeder 130 to feed quickly at a high frequency. After reaching 80% of the target weighing value, the frequency is switched to slow feeding. After reaching 99% of the target weighing value, the PLC stops the feeding electric vibrator 131 and waits for 15 seconds for the value to stabilize, and reminds manual feeding. After the manual feeding is completed, press the confirmation button to link the control system of the transport component 300, open the cylinder of the quantitative hopper 120, and drive the flap and the batching electric vibrator through the transmission rod to batch. When the weighing value is 0, the batching electric vibrator is stopped and the bottom valve of the quantitative hopper 120 is closed, thereby forming a closed-loop operation (see the attached manual for details). Figure 7 ).

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
