Description

Technical Field

[0001] The invention relates to the technical field of weighing belt conveyors, in particular to a combined weighing belt conveyor. Background Art

[0002] A belt scale is a weighing instrument that automatically weighs loose materials placed on a belt and passing continuously with the belt. Currently, a weighing belt conveyor is required to weigh additives during the preparation of aluminum alloys to solve the problems of high labor costs and low production efficiency caused by traditional manual operations.

[0003] The existing weighing belt conveyor pours the additives directly onto the conveyor belt during operation. Although the weight of the additives can be weighed during the conveying process, the additives on the conveyor belt are uneven. Some positions have more additives piled up, while others have less. Therefore, the quantitative weighing process is prone to errors in the results, which are not accurate enough. In many cases, the weight exceeds the required weight, especially at positions where more additives are piled up. Summary of the invention

[0056] The method of using the combined weighing belt conveyor includes the following specific steps:

[0057] S1. First, the additive is put into the storage box 402, and then the controller 9 controls the third motor 612 and the weighing sensor 707 to work, and the weighing sensor 707 starts to weigh. When the value obtained by the weighing sensor 707 is less than the first value range, the weighing sensor 707 sends a signal to the controller 9. At this time, the controller 9 controls the first motor 310 to start working, thereby controlling the first conveyor belt 305 to quickly convey the additive, and convey the additive to the third conveyor belt 704. During the conveying process, the first guide shell 503 pushes the additive to the middle of the first conveyor belt 305, and flattens it under the action of the first material balancing port 504 and the first toggle rod 505, and at the same time, the large pieces of additive bonded together are broken or filtered out;

[0058] S2. When the value obtained by the weighing sensor 707 is within the first value range, the weighing sensor 707 sends a signal to the controller 9. At this time, the controller 9 controls the first motor 310 to stop working and controls the second motor 311 to start working, thereby controlling the second conveyor belt 309 to slowly convey the additive and convey the additive to the third conveyor belt 704. During the conveying process, the second guide shell 508 pushes the additive to the middle of the second conveyor belt 309, and flattens it under the action of the second material balancing port 509 and the second toggle rod 510, and at the same time, the large pieces of additive bonded together are broken or filtered out;

[0059] S3, when the value obtained by the weighing sensor 707 is within the second value range, the weighing sensor 707 sends a signal to the controller 9, and the controller 9 controls the second motor 311 to stop working, and controls the fourth motor 705 to start working, thereby controlling the third conveyor belt 704 to rotate, and sending the additive into the discharge hopper 801 for unloading, and at the same time the scraper 803 scrapes off the additive adhered to the first conveyor belt 305, so that the use of the additive reaches the use range, and the next accurate weighing;

[0060] S4. During the process of conveying additives by the first conveyor belt 305 and the second conveyor belt 309, the driving shaft 606 controls the rotation of the toggle plate 607, the first fixed wheel 609 and the second fixed wheel 610. During the rotation, the toggle plate 607 pushes the fixed plate 608 to make the collecting hopper 601 vibrate left and right to prevent the additives from sticking to the collecting hopper 601. The rotation of the first fixed wheel 609 and the second fixed wheel 610 drives the brush 611 to clean the first conveyor belt 305 and the second conveyor belt 309 to prevent the additives from sticking to the first conveyor belt 305 and the second conveyor belt 309.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
