Description

Technical Field

[0001] The utility model relates to the technical field of sorting and grading terminals, in particular to a tobacco feeding and sorting and grading terminal. Background Art

[0002] Tobacco leaf sorting is an important link in the tobacco industry chain. Its purpose is to classify the picked tobacco leaves according to quality, grade and purpose. This process is crucial to ensure the quality of tobacco products and meet market demand. The sorted tobacco leaves will be used for different tobacco products such as cigarettes, cigars, pipe tobacco, etc. according to their grade and characteristics. High-quality tobacco leaves are usually used to make high-end tobacco products, while tobacco leaves of slightly lower quality may be used to make low-end products or as a component of blended tobacco.

[0003] During the sorting process, the tobacco leaves are first transported to the conveyor belt and then scanned by the intelligent recognition system. The recognition system compares the information of the tobacco leaves with the preset parameters or standards, and then sorts the tobacco leaves into the corresponding containers or channels according to the comparison results for subsequent processing and use. When placing the tobacco leaves on the conveyor belt, the tobacco leaves that have just come into contact with the conveyor belt will not immediately maintain the same moving speed as the conveyor belt due to inertia because the conveyor belt moves at high speed. Instead, there will be an acceleration process, during which the tobacco leaves move backward relative to the conveyor belt, and since the feeding mechanism cannot press the tobacco leaves on the conveyor belt, if the tobacco leaves are pressed on the conveyor belt, the friction between the conveyor belt and the tobacco leaves will cause damage to the tobacco leaves. Generally, the tobacco leaves are placed above the conveyor belt and are automatically dropped down. Since the tobacco leaves are in the air and are not in close contact with the conveyor belt, and the conveyor belt rotates at high speed. This causes the tobacco leaves to flip and fold when they just come into contact with the output belt and move backward relative to the conveyor belt. It is easy to fold the unfolded tobacco leaves together. This situation is not conducive to photographing and identifying tobacco leaves, which leads to reduced sorting effect. Utility Model Content

[0037] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0038] The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0039] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0040] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figure 1-2 As shown, the utility model proposes a tobacco loading and sorting and grading terminal, including a base 1, and also includes a material box 4. The tobacco leaves can be placed inside the material box 4 after being stacked together flatly. A lifting mechanism for driving the material box 4 to lift and lower is installed on the base 1. The lifting mechanism includes two second telescopic rods 401 fixedly installed on the base 1, and the second telescopic rods 401 are fixedly connected to the material box 4. A push rod motor 402 is fixedly installed on the base 1, and the output shaft of the push rod motor 402 is fixedly connected to the material box 4. The second telescopic rod 401 guides the material box 4 so that the material box 4 can only move along the axial direction of the second telescopic rod 401. The push rod motor 402 can drive the material box 4 to move along the axial direction of the second telescopic rod 401.

[0043] like Figure 1-4 As shown, the terminal device also includes a feeding mechanism fixedly mounted on the base 1, and a conveying mechanism is installed on the base 1. The feeding mechanism continuously places tobacco leaves on the conveying mechanism at equal intervals. The feeding mechanism includes a support plate 2 slidably mounted on the base 1, telescopic rods 201 fixedly mounted on both sides of the support plate 2, a suction plate 202 fixedly mounted on the two telescopic rods 201, and a plurality of suction heads 203 fixedly mounted on the suction plate 202. The suction plate 202 is provided with an air inlet 204. A driving assembly is installed on the base 1, and the driving assembly drives the suction plate 202 to reciprocate. Since the base 1 is slidably connected to the support plate 2, and through the guiding effect of the first telescopic rod 201, the suction plate 202 can only be lifted and lowered along the axis direction of the first telescopic rod 201 and slide in the left and right directions. The suction plate 202 cannot rotate. The suction head 203 on the suction plate 202 can be driven to move to the lower left by the driving assembly, so that the suction head 203 moves to the top of the material box 4, connects the external air source with the air inlet 204, and applies negative pressure to the suction head 203, so that the suction head 203 generates suction force on the outside, and the suction head 203 moved above the material box 4 generates suction force on the tobacco leaves inside the material box 4. When the tobacco leaves are adsorbed on the suction head 203, the suction head 203 can be driven to move to the conveying mechanism by the driving assembly, and at this time, the suction head 203 does not generate suction force on the tobacco leaves, and the tobacco leaves can fall onto the conveying mechanism under the action of gravity.

[0044] Further, the driving assembly includes two vertical plates 3 fixedly mounted on the base 1, the vertical plates 3 are provided with arc-shaped slide grooves 301, rollers 302 are rotatably mounted on both sides of the suction plate 202, the rollers 302 are located inside the arc-shaped slide grooves 301, a connecting block 303 is rotatably mounted on the rollers 302, a first telescopic rod 304 is fixedly mounted on the connecting block 303, a support block 305 is fixedly mounted on the other end of the first telescopic rod 304, the support block 305 is rotatably connected to the base 1, a rocker 306 is fixedly mounted on the support block 305, a connecting rod 307 is rotatably mounted on the rocker 306, a crank 308 is rotatably mounted on the connecting rod 307, a motor 309 is fixedly mounted on the base 1, and the output shaft of the motor 309 is fixedly connected to the crank 308. Starting the motor 309 can drive the crank 308 to perform circular motion, and the rocker 306 can be driven to swing back and forth through the transmission of the connecting rod 307. The reciprocating swing of the rocker 306 can drive the support block 305 to rotate, and the rotating support block 305 can drive the first telescopic rod 304 to rotate. The first telescopic rod 304 can drive the roller 302 to move inside the arc-shaped slide groove 301, thereby driving the suction plate 202 to move in an arc along the path of the arc-shaped slide groove 301.

[0045] The conveying mechanism includes a mounting frame 5 fixedly mounted on the base 1, a first transmission belt 6 fixedly mounted in the mounting frame 5, and a plurality of second transmission belts 9 rotatably mounted on the mounting frame 5. The first transmission belt 6 and the adjacent second transmission belts 9 fit each other, and the two adjacent second transmission belts 9 fit each other. The first transmission belt 6 is located on one side of the suction plate 202. The tobacco leaves conveyed by the suction plate 202 will first fall onto the first transmission belt 6, and then enter the second transmission belt 9 through the first transmission belt 6.

[0046] like Figure 4-5As shown, the terminal device has an adsorption component. Specifically, the adsorption component is installed on the base 1, and the adsorption component quickly moves at the same speed as the conveying mechanism for the tobacco leaves moving above the conveying mechanism. The adsorption component includes a plurality of adsorption holes 601 arranged on the first transmission belt 6, an adsorption box 8 fixedly installed on the base 1, a fan 801 fixedly installed in the adsorption box 8, and an air blowing box 803 fixedly installed on the base 1. An air pipe 802 is connected between the adsorption box 8 and the air blowing box 803. The adsorption box 8 is located below the first transmission belt 6, and the air blowing box 803 is located above the first transmission belt 6. When the fan 801 is started, the gas will enter the adsorption box 8 through the top of the adsorption box 8. Due to the setting of the adsorption holes 601, the adsorption box 8 adsorbs the gas above the first transmission belt 6. In addition, the tobacco leaves falling above the first transmission belt 6 can be adsorbed. Thereby, the tobacco leaves fall quickly and are closely attached to the first transmission belt 6, thereby increasing the friction between the tobacco leaves and the first transmission belt 6, speeding up the process of accelerating the tobacco leaves, and making the tobacco leaves quickly maintain the same speed as the first transmission belt 6. In the process of accelerating, the first transmission belt 6 adsorbs the tobacco leaves, which can prevent the tobacco leaves from curling. The wind blown out by the fan will be blown out through the air blowing box 803 through the conduction of the air pipe 802, which can further prevent the tobacco leaves from curling and increase the friction between the tobacco leaves and the first transmission belt 6. Thereby, the flatness of the tobacco leaves on the first transmission belt 6 can be improved, and the reduction of the recognition effect caused by the curling of the tobacco leaves can be prevented.

[0047] For further information, see Figure 5-6 As shown, the terminal device also includes an identification device 7 installed on the mounting frame 5. The identification device 7 is located above the first transmission belt 6. The identification device identifies the quality of the tobacco leaves passing through the first transmission belt 6. A sorting mechanism is installed on the base 1. The sorting mechanism controls the flow path of the tobacco leaves according to the identification device 7. The sorting mechanism includes a plurality of hydraulic rods 10 rotatably mounted on the base 1. The output shaft of the hydraulic rod 10 is rotatably connected to the second transmission belt 9. A plurality of classification boxes 11 are fixedly installed on the base 1. The identification device 7 uses a high-resolution camera and advanced image processing software to take real-time photos of the tobacco leaves traveling on the conveyor belt. By analyzing the shape, color, texture and other characteristics of the tobacco leaves, the computer can determine the variety and grade of the tobacco leaves. Multiple classification boxes 11 are used to place tobacco leaves of different grades. The second transmission belt 9 can be driven to rotate on the mounting frame 5 by the contraction of the hydraulic rod 10. A gap is formed between two adjacent second transmission belts 9. The tobacco leaves can flow into the classification box 11 through the gap. Different hydraulic rods 10 can control different second transmission belts 9 to control the tobacco leaves to enter different classification boxes 11, thereby completing the classification of the tobacco leaves.

[0048] The working principle of the utility model is as follows: after the tobacco leaves are stacked together flatly, the tobacco leaves can be placed inside the material box 4. The crank 308 can be driven to perform circular motion by starting the motor 309, and the rocker 306 can be driven to swing back and forth through the transmission of the connecting rod 307. The support block 305 can be driven to rotate through the reciprocating swing of the rocker 306, and the rotating support block 305 can drive the first telescopic rod 304 to rotate, and the first telescopic rod 304 can drive the roller 302 to move inside the arc chute 301, thereby driving the suction plate 202 to move in an arc along the path of the arc chute 301. The suction head 203 is moved to the top of the material box 4, so that the suction head 203 moved to the top of the material box 4 generates suction force on the tobacco leaves inside the material box 4. When the tobacco leaves are adsorbed on the suction head 203, the suction head 203 does not generate suction force on the tobacco leaves at this time, and the tobacco leaves can fall onto the first transmission belt 6 under the action of gravity. As the tobacco leaves in the material box 4 continue to decrease, the push rod motor 402 drives the material box 4 to move upward to ensure that the suction head 203 can contact the tobacco leaves. Start the fan 801, so that the adsorption box 8 adsorbs the gas above the first transmission belt 6. Then, the tobacco leaves falling above the first transmission belt 6 can be adsorbed. The tobacco leaves are closely attached to the first transmission belt 6, so that the friction between the tobacco leaves and the first transmission belt 6 can be increased, and in the process of accelerating the tobacco leaves, the first transmission belt 6 adsorbs the tobacco leaves, which can prevent the tobacco leaves from curling. The wind blown by the fan will be blown out through the air blowing box 803 through the conduction of the air pipe 802, which can further prevent the tobacco leaves from curling, improve the flatness of the tobacco leaves on the first transmission belt 6, and prevent the identification effect from being reduced due to the curling of the tobacco leaves. The identification device 7 can determine the variety and grade of the tobacco leaves. The second transmission belt 9 can be driven to rotate on the mounting frame 5 by contracting the hydraulic rod 10, so that a gap appears between two adjacent second transmission belts 9, and tobacco leaves can flow into the classification box 11 through the gap. By controlling different second transmission belts 9 with different hydraulic rods 10, tobacco leaves can be controlled to enter different classification boxes 11, thereby completing the classification of tobacco leaves.
