[0002] Tobacco is a plant of the genus Nicotiana in the Solanaceae family and is a leaf-based cash crop. In order to increase the availability of upper tobacco leaves, many producing areas have begun to promote the technology of picking and roasting upper tobacco leaves with stems. This roasting and curing method requires the tobacco leaves to be separated from the stems before purchase, and the leaves are graded and purchased based on their appearance quality, and any non-tobacco substances such as stems are not allowed to be mixed in.

[0003] In the process of separating tobacco leaves and tobacco rods, auxiliary tools are needed, for example, a leaf stripping device for tobacco stalks with leaves after roasting with application number: "201710998593.9", comprising a frame, a tobacco stalk adaptive device and a tobacco stalk clamping and moving device, wherein a workbench is fixedly arranged at one end of the frame, and a tobacco stalk adaptive device is arranged on the workbench, the tobacco stalk adaptive device comprises a fixed disk and a guide tube, the fixed disk is annular, and one side of the fixed disk is integrally provided with a plurality of slide grooves, and a fan ring block is slidably connected to the slide groove, and the plurality of fan ring blocks are surrounded by annular shape and form a rod inlet, and the annular hole on the fixed disk is fixedly connected to the guide tube, and the guide tube is located on the other side of the fixed disk; a limited stopper is arranged on the annular hole of the fixed disk; a spring is arranged at the outer arc of the fan ring block, and an extension plate is fixedly connected to the outer edge of the fixed disk, one end of the spring presses on the outer arc of the corresponding fan ring block, and the other end of the spring presses on the extension plate, and an arc blade is fixedly assembled on the outer wall of the inner arc of the fan ring block. The invention has a simple structure and is easy to use, and can effectively reduce the labor intensity of workers, improve work efficiency, and reduce the damage rate of tobacco leaves.

[0004] The current technical solution for separating the stems and leaves mainly utilizes the impact of a knife to cut the tobacco leaves from the stems. In actual application, due to the large difference in the diameter of the tobacco stems before and after, a small part of the surface of the tobacco stems is often cut off along with the petioles, causing non-tobacco substances to mix into the tobacco leaves, which is a taboo in tobacco production; or the base of the petiole at the junction of the stems and leaves is broken due to the impact of the blade, resulting in a part of the tobacco leaves remaining on the outer wall of the tobacco stem after cutting and peeling. Although it does not affect the quality of the tobacco leaves, the weight loss will cause a loss of income to the growers, which is unacceptable to the growers. That is, the auxiliary tools in the prior art are not accurate enough in controlling the cutting and peeling position of the tobacco leaves, and the cutting method is not precise enough, and they cannot adapt to and meet the needs of industrial development.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0026] The current technical solution for separating the stems and leaves mainly utilizes the impact of a knife to cut the tobacco leaves from the stems. In actual application, due to the large difference in the diameter of the tobacco stems before and after, a small part of the surface of the tobacco stems is often cut off along with the petioles, causing non-tobacco substances to mix into the tobacco leaves, which is a taboo in tobacco production; or the base of the petiole at the junction of the stems and leaves is broken due to the impact of the blade, resulting in a part of the tobacco leaves remaining on the outer wall of the tobacco stem after cutting and peeling. Although it does not affect the quality of the tobacco leaves, the weight loss will cause a loss of income to the growers, which is unacceptable to the growers. That is, the auxiliary tools in the prior art are not accurate enough in controlling the cutting and peeling position of the tobacco leaves, and the cutting method is not precise enough, and they cannot adapt to and meet the needs of industrial development.

[0027] In view of this, the present invention provides a machine for accurately separating stems and leaves of tobacco leaves after modulation with stems. Through the cooperation among the driving wheel, the driven wheel, the limiting rod, the spring, the arc saw blade, the disc and the transmission rod, the root of the tobacco rod is automatically pulled. As the tobacco rod moves, the arc saw blade adjusts its position at all times under the drive of the driven wheel and the limiting rod, to ensure that the growth positions of the arc saw blade and the tobacco leaves are accurately coordinated, and precise cutting is achieved, that is, it is ensured that no tobacco rods are mixed into the interior of the tobacco leaves, and at the same time, the completeness of the cutting of the tobacco leaves is guaranteed, the interests of the growers are guaranteed, and a balance is achieved. In addition, automatic cutting and peeling are performed only after manual filling, and the efficiency is greatly improved.

[0028] Depend on Figure 1-5 It can be seen that a precise separation machine for separating stems and leaves of tobacco leaves with stems after curing in this case includes a feed hopper 1, a classification and collection device is arranged at the bottom of the feed hopper 1, and cutting components are arranged on both sides of the inside of the feed hopper 1; the cutting component includes a limit rod 2, a driving wheel 3, a driven wheel 4, a spring 5, a limit seat 6, a slide rail 7, a slider 8, an arc-shaped saw blade 9, a transmission rod 10, a disc 11 and a servo motor 12; there are two limit rods 2, and they are vertically distributed up and down, the end of the limit rod 2 located at the top is equipped with a driven wheel 4, and the end of the limit rod 2 located at the bottom is equipped with a driving wheel 3, the outer wall of the limit rod 2 passes through the side wall of the feed hopper 1, and is slidably engaged with the feed hopper 1, and the limit rod 2 One end located outside the feed hopper 1 is threadedly connected to the limit seat 6, and the outer wall of the limit rod 2 is sleeved with a spring 5, and the two ends of the spring 5 are respectively pressed against the inner wall of the feed hopper 1 and the outer wall protrusion of the limit rod 2, and the top of the limit rod 2 located above is fixedly connected with a slide rail 7, and a slider 8 is slidably clamped on the top inner surface of the slide rail 7, and an arc-shaped saw blade 9 is fixedly connected to the top of the slider 8. One side of the arc-shaped saw blade 9 is rotatably connected to a transmission rod 10 through a pin shaft, and a disc 11 is arranged at the bottom of the transmission rod 10. One side of the top of the disc 11 is rotated critically with the end of the transmission rod 10 through a pin shaft, and a servo motor 12 is installed at the bottom of the disc 11, and the servo motor 12 is fixedly connected to the side wall of the slide rail 7.

[0029] In the specific implementation process, it is worth pointing out that the feed hopper 1 can be cylindrical. When in use, the tobacco leaves with stems are inserted into the feed hopper 1 from the root. Two groups of cutting components can be set. The two groups work synchronously and can complete a 360-degree cutting action inside the feed hopper 1. In this way, it is convenient to cut and peel tobacco leaves at all angles on the outer wall of the tobacco rod. A synchronizer is required to ensure that the two servo motors 12 work synchronously to avoid collision between the two arc saw blades 9. Among them, the two upper and lower limit rods 2 can ensure that the driving wheel 3 and the driven wheel 4 are always in contact with the outer wall of the tobacco rod under the action of the spring 5. The outer wall of the driving wheel 3 can be provided with teeth to increase the friction with the tobacco rod. The two driving wheels 3 run synchronously to give the tobacco rod a traction force to move downward. At the same time, the arc saw blade 9 is driven by the servo motor 12 under the cooperation of the transmission rod 10, the slider 8 and the slide rail 7. It performs circular arc reciprocating motion, and the distance between the arc saw blade 9 and the tobacco rod is determined by the position of the driven wheel 4, and the driven wheel 4 can keep in contact with the tobacco rod at all times. Since tobacco leaves grow on the outer wall of the tobacco rod, when the driven wheel 4 is in contact with the outer wall of the tobacco rod and just above the driven wheel 4 close to the tobacco leaf growth position, the arc saw blade 9 can quickly and completely cut and separate. The size design of the feed hopper 1 and the arc saw blade 9 must meet the requirement that when the tobacco rod is located between the two arc saw blades 9, compared with traditional technology, it can avoid cutting off the tobacco rod part and ensure the purity of the tobacco leaves. At the same time, no larger tobacco leaf part will remain on the outer wall of the tobacco rod, thereby ensuring the profits of tobacco growers and avoiding waste. It ensures the purity of tobacco while ensuring the profits of growers, achieving a balance between the two, and automatic stripping is more efficient. Compared with manual operation, it saves time and effort and reduces labor costs.

[0030] Furthermore, a ball bearing is cooperatively connected between the slide rail 7 and the slide block 8 .

[0031] In the specific implementation process, it is worth pointing out that such a design can reduce the friction between the slide rail 7 and the slider 8.

[0032] In one practicable manner, see Figure 2 and Figure 3 An elastic protective sleeve 13 is arranged above the inside of the feed hopper 1 , the upper part of the outer wall of the elastic protective sleeve 13 is fixedly connected to the inner wall of the feed hopper 1 , and the bottom of the elastic protective sleeve 13 is fixedly connected to the top of the arc-shaped saw blade 9 .

[0033] During the specific implementation process, it is worth pointing out that the elastic protective sleeve 13 is cylindrical, with its two ends respectively fixed to the inner wall of the feed hopper 1 and the top of the arc saw blade 9. The elastic material can ensure the normal operation of the arc saw blade 9, while preventing tobacco debris and the like from entering the interior of the cutting assembly, thereby ensuring the normal operation of the cutting assembly. It can also play a role in safety protection, preventing the operator's hands from directly contacting structures such as the disc 11 and the transmission rod 10.

[0034] Furthermore, a collecting tank 14 is fixedly connected to the top of the feed hopper 1 .

[0035] In the specific implementation process, it is worth pointing out that the collecting trough 14 is annular and is arranged above the feed hopper 1. The cut tobacco leaves fall into it and are automatically collected. Of course, a conveying mechanism can be installed inside the collecting trough 14 to achieve automatic transportation of tobacco leaves.

[0036] In one practicable manner, see Figure 1 and Figure 6 The classification and collection device includes a box body 15, a material distribution port 16, a conveyor belt 17, a material guide plate 18, a bracket 19, a cigarette rod rotating plate 20, a sensor control module 22 and an actuator 23; the top of the box body 15 is connected to the bottom of the feed hopper 1, and a plurality of material distribution ports 16 are provided at the bottom of the box body 15, and a conveyor belt 17 is correspondingly provided at the bottom of each material distribution port 16. A material guide plate 18 is provided inside the box body 15, and the bottom of the material guide plate 18 is rotatably connected to the bracket 19, and the bottom of the bracket 19 is fixedly connected to the inner wall of the box body 15. The top end of the material guide plate 18 is rotatably connected to the cigarette rod rotating plate 20, and a sensor control module 22 is embedded in the top of the material guide plate 18 near the cigarette rod rotating plate 20. The sensor control module 22 is electrically connected to the actuator 23, and the actuator 23 is used to drive the material guide plate 18.

[0037] In the specific implementation process, it is worth pointing out that the box 15 serves as a temporary collection device for the tobacco rods, wherein the tobacco leaves on the outer wall of the tobacco rods are cut from bottom to top in sequence by the annular saw blade 9 and fall into the interior of the collecting trough 14. However, in some cases, the tobacco leaves may fall into the interior of the box 15 along with the tobacco rods, and fall to the top of the tobacco rod rotating plate 20, and slide along its top to the top of the guide plate 18. At this time, the sensor control module 22 senses the number of tobacco leaves that have been cut and counts them. The grade of the tobacco leaves cut in the early stage is low, and the control actuator 23 is extended or retracted so that the end of the guide plate 18 is located above one of the distribution ports 16, that is, The tobacco leaves of this grade are conveyed out by one of the designated conveyor belts 17 for easy collection. The tobacco leaves cut in the middle period are of a slightly higher grade and better quality. The sensor control template 22 controls the actuator to rotate the end of the guide plate 18 to the bottom of another material distribution port 16 and convey it out by another designated conveyor belt 17. In this way, automatic multi-stage screening of tobacco leaves is realized. Finally, when the tobacco rod falls on the tobacco rod rotating plate 20, the rotating plate 20 rotates along the direction of the needle, so that the tobacco rod falls to a direction different from the tobacco leaves, which is convenient for classification. In this way, the problem that the tobacco leaves do not fall into the collecting trough 14 in some cases and the tobacco leaves and the tobacco rods are not easy to separate when entering the box body 15 can be solved.

[0038] It can be understood that the sensor control module 22 may include an infrared sensor, a counter and a control device to drive the actuator 23. At the same time, the actuator 23 may be a telescopic rod, such as an electric telescopic rod, a hydraulic rod and other devices. The specific model and type are not limited as long as the use requirements are met. The technical solution recorded in this application document only provides an implementable method, not all embodiments.

[0039] Furthermore, a torsion spring 21 is installed between the cigarette rod rotating plate 20 and the material guiding plate 18 .

[0040] During the specific implementation process, it is worth pointing out that the torsion spring 21 gives the cigarette rod rotating plate 20 a counterclockwise rotation force. Since the weight of the cigarette rod is much greater than the gravity of the tobacco leaves, the cigarette rod rotating plate 20 can be driven to rotate clockwise until the cigarette rod falls, and the cigarette rod rotating plate 20 returns to its original position under the action of the torsion spring 21.

[0041] Furthermore, a crushing compressor 24 is provided below the cigarette rod rotating plate 20 , and a feed port of the crushing compressor 24 extends to the interior of the material box 15 and is located below the cigarette rod rotating plate 20 .

[0042] In the specific implementation process, it is worth pointing out that the crushing compressor 24 can crush the fallen tobacco stems and compress them into blocks, thus achieving integrated processing. At the same time, they can be used as subsequent flue-cured tobacco fuel without the need for centralized processing.

[0043] It is understandable that the bracket 19 can be replaced by a gravity sensor. In this way, once the cigarette rod rotating plate 20 is accidentally stuck and cannot rotate automatically under the action of the gravity of the cigarette rod, the upright position can be transmitted to the sensor control module 22 through the gravity sensor. At this time, the sensor control module 22 controls the actuator 23 to work, so that the guide plate 18 and the cigarette rod rotating plate 20 rotate synchronously to ensure that the cigarette rod can fall in the opposite direction of the tobacco leaves.

[0044] Furthermore, a limiting plate 25 fixed to the inner wall of the box body 15 is provided between two adjacent material distribution ports 16 .

[0045] In the specific implementation process, it is worth pointing out that the design of the limiting plate 25 can better distinguish each material distribution opening 16, reduce the probability of tobacco leaves mistakenly entering other material distribution openings 16, and improve the accuracy of classification.

[0046] Furthermore, the top of the limiting plate 25 is conical.

[0047] In the specific implementation process, it is worth pointing out that the conical design can avoid tobacco leaves from getting stuck on the top of the limiting plate 25 to the greatest extent, thereby ensuring smooth unloading of subsequent tobacco leaves.

[0048] Comparative test:

[0049] Four flue-curing rooms with the same amount of tobacco are divided into flue-curing room 1, flue-curing room 2, flue-curing room 3 and flue-curing room 4. Flue-curing room 1 and flue-curing room 2 use the present invention to separate tobacco stems and tobacco leaves, and flue-curing room 3 and flue-curing room 4 use existing tools such as sickles and pruning knives to separate tobacco stems and tobacco leaves, and all separations are completed:
