[0002] In the cigarette production process, the cutting and drying of tobacco leaves are the core and key steps in tobacco processing. At the outlet of the thin plate drying machine in the leaf-making section, the leaf air separation process is used to remove foreign objects. That is, the air separation device is used to separate clumps, other foreign objects and stems from the leaf shreds, thereby improving the purity of the leaf shreds. This is also the main method for removing foreign objects in the current drying process.
[0003] Currently, the method for removing foreign objects and debris from tobacco leaves by air separation is to use cardboard boxes or other receiving containers to hold the foreign objects removed by air separation, and to manually weigh and record the weight of each batch of tobacco leaves removed by air separation at the outlet of the drying process.
[0004] Current technologies require manual operation, which is inefficient and necessitates manual recording of the weight of foreign objects, hindering automation. Furthermore, manual replacement of cardboard boxes is required to prevent excessive accumulation of foreign objects and debris in the receiving bin, which could clog the screw conveyor, cause motor overcurrent tripping, and interrupt production. Improving the automatic weighing of foreign objects at the air separator at the wire drying outlet, thereby reducing the intensity of manual weighing, is a key challenge that needs to be addressed in the wire drying process.
[0005] Therefore, an online metering device for removing material from blade air separation is proposed to address the above problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0017] Specific implementation examples are given below.
[0018] Please see Figures 1-6 This utility model provides an online metering device for removing leaf filaments by air separation, including a base plate 1, a control device, a power supply device, and a limit sensor. From left to right, the top of the base plate 1 is provided with a motor 2, a working reducer 3, a reducer connector 4, a rotating support 5, a ball bearing 6, and a working screw 7. The output shaft of the motor 2 is fixedly connected to one side of the working reducer 3 through a coupling. The working reducer 3 passes through one side of the reducer connector 4 and is fixedly connected to one end of the working screw 7. The rotating support 5 is installed on the top of the base plate 1. The surface of one end of the working screw 7 is rolledly connected to the surface of the ball bearing 6 through a helical pair. Guide rails 13 are fixedly connected to both sides of the top of the base plate 1. A slider 8 is slidably connected to the surface of the guide rails 13. A pad block 9 is fixedly connected to the top of the slider 8. A cover plate 12 is fixedly connected to the top of the slider 8 through the pad block 9. A pressure sensor 11 is fixedly connected to the lower surface of the cover plate 12. A fixed connecting plate 10 is fixedly connected to the bottom of the pressure sensor 11. The bottom of the fixed connecting plate 10 is rolledly connected to the surface of the ball bearing 6. The control device consists of a PLC controller. It controls the rotation of motor 2 via electrical signals. The control device is connected to pressure sensor 11 and limit sensor via electrical signals. The limit sensor is installed on one side of the conveyor belt to detect the height of foreign objects in the receiving bin. The control device can interact with the data acquisition system via a data interface. The power supply is connected to the control device and motor 2 via a power supply line. Before operation, the switch should be turned on to ensure motor 2 is in a ready-to-work state. Two receiving bins should be placed side-by-side on the cover plate 12. Simultaneously, pressure sensor 11 begins reading the weight of the rejected items in the receiving bins on the cover plate 12. The weight of the cover plate 12 and the receiving bins has been removed before pressure sensor 11 measures the weight of the rejected items. When foreign objects in the receiving bins... When the weight reaches 50 kg or the limit sensor detects that the height of the foreign object accumulation exceeds the set value, an electrical signal is fed back to the PLC part of the control device. At this time, the control device sends a control signal to start the motor 2. The base plate 1 supports the motor 2, the working reducer 3, the reducer connector 4, the rotating support seat 5, the ball bearing 6, and the working screw 7. The motor 2 transmits power to the working reducer 3. Then, the output shaft of the working reducer 3 drives the working screw 7 to move clockwise, which causes the ball bearing 6 to drive the fixed connecting plate 10 to move forward. At the same time, the slider 8 slides along the guide rail 13. After the control device reads the weighing data of the pressure sensor 11, it sends the data to the yarn production control system through the data interaction interface to save the leaf and yarn air separation rejection data.
[0019] Furthermore, such as Figure 1 and Figure 2As shown, the working reducer 3 and the reducer connector 4 are connected by bolts, and the reducer connector 4 is fixedly installed on the top of the base plate 1; the working reducer 3 is a planetary reducer, and the reduction ratio of the planetary reducer is 1.25. During operation, the reducer connector 4 uses bolts to fix the working reducer 3 together, and at the same time, the reducer connector 4 is fixedly installed on the top of the base plate 1 to support the reducer connector 4.
[0020] Furthermore, such as Figure 3 As shown, the working lead screw 7 consists of lead screw I 701, lead screw II 702, lead screw III 703, and lead screw IV 704. Lead screw I 701 has a diameter of 15 mm and a length of 12 mm; lead screw II 702 has a diameter of 20 mm, a length of 513 mm, and a pitch of 5 mm / rev; lead screw III 703 has a diameter of 15 mm and a length of 55 mm; and lead screw IV 704 has a diameter of 20 mm and a length of 12 mm. During operation, lead screw II 702 is used for wire twisting.
[0021] Furthermore, such as Figure 2 and Figure 6 As shown, the cover plate 12 has a concave symmetrical structure, with a height of 40 mm and a thickness of 10 mm. Four pressure sensors 11 are provided, arranged symmetrically in pairs on the top of the fixed connecting plate 10. During operation, the cover plate 12 protects the interior and supports the fixed connecting plate 10 and the pressure sensors 11, and can move along with the fixed connecting plate 10.
[0022] First, before use, the switch should be turned on to ensure that the motor 2 is in standby mode. Two receiving boxes should be placed side by side on the cover plate 12. At the same time, the pressure sensor 11 starts to read the weight of the rejected items in the receiving boxes on the cover plate 12. The weight of the cover plate 12 and the receiving boxes has been removed before the pressure sensor 11 measures the weight of the rejected items. When the weight of the foreign objects in the receiving boxes reaches 50 kg or the limit sensor detects that the height of the foreign objects exceeds the set value, an electrical signal will be fed back to the PLC part of the control device. At this time, the control device sends a control signal to start the motor 2. The base plate 1 supports the motor 2, the working reducer 3, the reducer connector 4, the rotating support seat 5, the ball bearing 6, and the working screw 7. The motor 2 transmits power to the working reducer 3. Then, the output shaft of the working reducer 3 drives the working screw 7 to move clockwise, so that the ball bearing 6 drives the fixed connecting plate 10 to move forward. At the same time, the slider 8 slides along the guide rail 13. After the control device reads the weighing data of the pressure sensor 11, it sends the data to the yarn-making centralized control system through the data interaction interface to save the leaf and yarn air separation rejection data. Meanwhile, the reducer connector 4 uses bolts to fix the working reducer 3 together, and the reducer connector 4 is fixedly installed on the top of the base plate 1 to support it. The working lead screw 7 consists of several parts: lead screw I 701, lead screw II 702, lead screw III 703, and lead screw IV 704, and lead screw II 702 is used for twisting the tobacco. Finally, the cover plate 12 protects the interior and supports the fixed connecting plate 10 and the pressure sensor 11, and can move with the fixed connecting plate 10. When the tobacco batch production is completed or the foreign object weighing is completed early, the weight data of the foreign object transmitted by the pressure sensor 11 can be collected by the operation control device and uploaded to the system. At this time, the receiving box on the cover plate 12 can be removed manually, and the device can be put into operation again. The entire system can collect the weight data of rejected materials in the receiving box in real time through the pressure sensor 11, and automatically change the box when the accumulated weight of foreign objects reaches the set value, reducing the labor intensity of manual weighing. At the same time, the fiber sensor detects the accumulation height of rejected materials to prevent excessive accumulation from causing blockage, effectively improving work efficiency and avoiding the risk of material interruption due to foreign object blockage. The system also uses the control device to interact with the yarn production control system to realize the automatic collection of rejected material data.
