Description

Technical Field

[0001] The utility model relates to the technical field of automatic measurement and weighing of raw iron sheets, in particular to an automatic measurement and weighing device for raw iron sheets. Background Art

[0002] Iron powder, a collection of iron particles less than 1 mm in size, is the primary raw material for powder metallurgy. Based on particle size, it is typically categorized into five grades: coarse, medium, fine, micro, and ultrafine. Iron powders with a particle size range of 150 to 500 μm are considered coarse powder, 44 to 150 μm are medium powder, 10 to 44 μm are fine powder, 0.5 to 10 μm are ultrafine powder, and less than 0.5 μm are ultrafine powder.

[0003] The raw material used in the iron powder production process is iron flakes. However, they need to be weighed before processing. The existing weighing method uses a small floor scale with a single weighing bucket. After weighing, the weighing bucket is moved to a cart and transported to the processing workshop. The back-and-forth movement and weighing increase the labor of workers and waste a certain amount of time. To this end, we provide an automatic weighing device for raw iron flakes to solve the above problems. Utility Model Content

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1-5 shown, the present invention provides a technical solution: an automatic metering and weighing device for raw material iron sheets, including a bottom plate 1. A support plate 5 that moves up and down is arranged above the bottom plate 1. Support springs 9 are evenly arranged between the bottom plate 1 and the support plate 5, and a weight meter 10 is arranged in the support springs 9 and between the bottom plate 1 and the support plate 5. A placing groove 14 is opened on the support plate 5, a pressure sensor 12 is arranged in the placing groove 14, trigger blocks 13 are evenly arranged at the bottom end of the placing groove 14, a connecting seat 7 is arranged in the placing groove 14, and a measuring bucket 6 is arranged on the connecting seat 7. Trigger grooves 18 and grooves 17 are opened at the bottom end of the connecting seat 7, and the trigger grooves 18 and the grooves 17 are respectively located directly above the trigger blocks 13 and the pressure sensors 12. A weight display lamp 8 is arranged on the surface of the connecting seat 7, a handle 4 is arranged on the surface of the bottom plate 1, and universal wheels 2 are arranged on the bottom surface of the bottom plate 1. By using the pressure sensor 12, the trigger block 13 and the weight meter 10, the weight in a single measuring bucket 6 can be weighed, and at the same time, the total weight of multiple measuring buckets 6 can be weighed by using the weight meter 10. When the weight display lamp 8 is used, it can automatically light up when the gravity in each measuring bucket 6 reaches the requirement, prompting the operator. Compared with the traditional method of using a single small weighing scale for weighing, it reduces the cumbersome steps, saves time, and can also reduce the multiple up and down handling.

[0024] Specifically, as Figure 4As shown, an annular threaded groove 15 is formed in the connecting base 7, and an annular threaded block 16 is threadedly connected in the annular threaded groove 15. The upper part of the annular threaded block 16 is fixed to the bottom end of the metering barrel 6. A limiting groove 11 is formed in the bottom plate 1, and an L-shaped limiting block 3 is arranged in the limiting groove 11. The L-shaped limiting block 3 is fixed to the bottom end of the support plate 5. The L-shaped limiting blocks 3 are evenly arranged around the bottom plate 1. By providing the annular threaded groove 15 and the annular threaded block 16, the metering barrel 6 and the connecting base 7 can be connected, which is convenient for the staff to replace the metering barrel 6 or the connecting base 7. The limiting groove 11 and the L-shaped limiting block 3 are used between the support plate 5 and the bottom plate 1 to limit the support plate 5, preventing the support plate 5 from shaking during movement and avoiding the iron sheets in the metering barrel 6 from spilling.

[0025] Specifically, as Figure 5 shown, the bottom plate 1 further includes a built-in processing unit 19 and a storage 20, and the processing unit 19 is electrically connected to the weight display lamp 8, the weight meter 10, the pressure sensor 12 and the storage 20. By providing the processing unit 19 and the storage 20 in the bottom plate 1, the lighting and turning off of the weight display lamp 8 can be controlled. At the same time, the total weight of a single metering barrel 6 and multiple metering barrels 6 can be stored, realizing the recording of the overall weight and also realizing the paperless recording operation.

[0026] Working principle: When in use, the operator first inputs the weight of each metering barrel 6 into the storage 20 of the overall device through an external programming controller. The metering barrel 6 and the connecting base 7 are connected through the annular threaded block 16 and the annular threaded groove 15. After connection, multiple metering barrels are respectively placed in the placement grooves 14 on the support plate 5. The overall device is pushed to the raw material iron sheet location through the handle 4 and the universal wheels 2 at the bottom end of the bottom plate 1. Then, raw material iron sheets are put into the metering barrel 6 through an external feeding device. The metering barrel 6 and the connecting base 7 will move downward in the placement groove 14. At the same time, the bottom groove 17 of the connecting base 7 will also squeeze the pressure sensor 12, and the trigger groove 18 will also contact the trigger block 13. When the weight of the raw material iron sheets in a single metering barrel 6 reaches the weight set in the storage 20, the processing unit 19 will turn on the weight display lamp 8 on the surface of the connecting base 7, and then start adding raw material iron sheets to the next metering barrel 6. When all the metering barrels 6 are installed, the support plate 5 will squeeze the support spring 9 between the support plate 5 and the bottom plate 1 downward, thereby triggering the weight meter 10 placed in the middle of the support spring 9. The weight meter 10 will store the overall weight data and transmit the data to the external controller at the same time. Then, the overall device is moved to the designated location through the handle 4 and waits for the use of the raw material iron sheets in the metering barrel 6.
