Description

Technical Field

[0001] This utility model relates to the field of cigarette processing technology, and in particular to a box-turning feeding device. Background Technology

[0002] In the initial processing of tobacco leaves, the dried tobacco leaves are generally packed into wooden tobacco boxes. The tobacco boxes containing the tobacco leaves are then transported by a conveyor belt. The conveyor belt connects to the tobacco processing production line, and then the tobacco boxes are flipped by a tobacco box flipping mechanism, so that the tobacco leaves inside fall onto the conveyors on the tobacco processing production line. The conveyors then send the tobacco leaves to various processing stations on the tobacco processing production line for processing.

[0003] However, during the tobacco box turning process, dried tobacco leaves tend to adhere to the bottom of the box. The current method involves extending the cleaning end of the tobacco box cleaning mechanism into the box to clean away any remaining or attached tobacco leaves. The cleaned leaves then fall onto a conveyor on the tobacco processing production line, from where they are transported to various processing stations. While the combination of the tobacco box turning mechanism and the cleaning mechanism can remove the attached tobacco leaves from the bottom of the box, the following drawbacks still exist in the actual cleaning process:

[0004] When the tobacco box turning mechanism turns the tobacco box, it is often necessary to manually adjust and calibrate it repeatedly before the tobacco box cleaning mechanism can complete the cleaning process of the attached tobacco leaves. This not only reduces the efficiency of cleaning the attached tobacco leaves, but also increases the labor intensity of manual labor.

[0005] Therefore, it is necessary to improve and redesign the method of cleaning residual tobacco leaves inside the tobacco box to solve the problem that when cleaning residual tobacco leaves inside the tobacco box, the tilting mechanism cannot be tilted to the optimal angle for the cleaning mechanism to work, and multiple manual adjustments and calibrations are still required before the cleaning mechanism can complete the cleaning of residual tobacco leaves inside the tobacco box. Utility Model Content

[0006] The purpose of this utility model is to propose a box-turning feeding device to solve the problem that when cleaning residual tobacco leaves inside the tobacco box, the box-turning mechanism cannot be turned to the optimal angle for the cleaning mechanism to operate, and multiple manual adjustments and calibrations are still required before the cleaning mechanism can complete the cleaning of residual tobacco leaves inside the tobacco box.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A tobacco box tipping and feeding device includes a tobacco box conveying assembly, a tobacco box tipping mechanism, a tobacco leaf conveying assembly, and a cleaning mechanism. The tobacco box tipping mechanism is located at the discharge end of the tobacco box conveying assembly. A first sensor and a second sensor are respectively connected to a drive component that drives the tobacco box tipping mechanism to tip via a PLC controller. The first sensor is located on the tobacco box tipping mechanism near the discharge end of the tobacco box conveying assembly, and the second sensor is located on the inner wall of a support arm in the tobacco box tipping mechanism that is used for rotational connection of part of the tobacco box tipping mechanism. The discharge end of the tobacco box tipping mechanism is connected to the feed end of the tobacco leaf conveying assembly. The cleaning end of the cleaning mechanism is located above the connection between the feed end of the tobacco leaf conveying assembly and the discharge end of the tobacco box tipping mechanism. The cleaning mechanism is located on one side of the tobacco leaf conveying assembly and is also connected to the second sensor via a PLC controller.

[0009] Furthermore, the cigarette box conveying assembly includes a first conveying bracket and a roller conveyor; two roller conveyors are respectively connected between the two first conveying brackets, and a gap is reserved between the two roller conveyors. A cigarette box turning mechanism is provided between the discharge ends of the two roller conveyors.

[0010] Furthermore, the cigarette box flipping mechanism also includes a support arm and a cigarette box clamp; the bottom of the support arm is connected to the conveying frame of the two roller conveyors respectively, the driving component is rotatably connected to the two support arms, the driving component is sleeved with the through hole at one end of the L-shaped connecting rod, and the other end of the L-shaped connecting rod is connected to the bottom of the cigarette box clamp.

[0011] Furthermore, the driving component includes a flip drive shaft and a flip drive assembly; the flip drive assembly is connected to the side wall of one of the supporting arms, the output shaft of the flip drive assembly is rotatably connected to the side wall of one of the supporting arms, one end of the flip drive shaft located between the two supporting arms is connected to the output shaft of the flip drive assembly, both ends of the flip drive shaft are rotatably connected to the two supporting arms respectively, the flip drive shaft is sleeved with the through hole at one end of the L-shaped connecting rod, and the other end of the L-shaped connecting rod is connected to the bottom of the cigarette box clamp.

[0012] Furthermore, the flipping drive is a flipping motor.

[0013] Furthermore, the cigarette box clamp includes a "door"-shaped flipping frame, a cylinder, and a clamping plate; the bottom of the "door"-shaped flipping frame is connected to one end of an L-shaped connecting rod, and connecting plates are respectively connected between the frames on the inner side wall of the "door"-shaped flipping frame. The inner side wall of the connecting plate is respectively connected to the fixed end of the cylinder, and the driving end of the cylinder is respectively connected to the side wall of the clamping plate.

[0014] Furthermore, the first sensor is located on the lower half of one inner wall of the "door"-shaped tilting frame, and the second sensor is located on the upper half of the inner wall of one of the supporting arms. The second sensor and the first sensor are electrically connected to the tilting motor through a PLC controller.

[0015] Furthermore, the tobacco leaf conveying assembly includes a feeding bin and a conveyor; the feeding end of the feeding bin is located on one side of the "gate"-shaped tilting frame, the outer wall of the feeding bin is connected to the second conveyor frame in the conveyor through a support frame, and the discharging end of the feeding bin is located directly above the feeding end of the belt conveyor.

[0016] Furthermore, the cleaning mechanism includes a support frame, a linear slide module, a cleaning robotic arm, and a cleaning brush; the support frame is located on one side of the feeding end of the second conveyor frame, the support frame is connected to the outer wall of the linear slide module, the moving end of the linear slide module is connected to the cleaning robotic arm, the executing end of the cleaning robotic arm is connected to the cleaning brush, and the cleaning brush is located above the connection between the feeding end of the feeding bin and the discharge end of the "door" shaped tilting frame.

[0017] During the working process, when the dried tobacco leaves are conveyed to the processing station on the tobacco leaf conveying assembly for initial processing, the dried tobacco leaves are loaded into the tobacco box on the tobacco box conveyor. The tobacco box conveyor transports the tobacco box containing the dried tobacco leaves to the tobacco box turning mechanism, which clamps and locks the tobacco box containing the tobacco leaves. At the same time, the first sensor on the tobacco box turning mechanism detects that the tobacco box is in place. The first sensor then controls the drive component that drives the tobacco box turning mechanism to turn clockwise through the PLC controller.

[0018] When the tobacco box is flipped to the second sensor on the tobacco box flipping mechanism and detected, the tobacco box flipping mechanism flips the tobacco box to a position that facilitates both cleaning and unloading of tobacco leaves. The second sensor, through the PLC controller, stops the drive component that drives the tobacco box flipping mechanism. The tobacco leaves inside the tobacco box slide from the tilted tobacco box into the tobacco leaf conveying assembly. Then, the tobacco leaf conveying assembly transports the fallen tobacco leaves to various processing stations on the tobacco processing production line for initial processing. At the same time, the second sensor, through the PLC controller, controls the cleaning mechanism to operate. The cleaning end of the cleaning mechanism extends into the inside of the tobacco box after the tobacco leaves have been unloaded to clean the tobacco leaves attached to the bottom of the tobacco box. The cleaned tobacco leaves slide onto the tobacco leaf conveying assembly and continue to be transported to various processing stations for initial processing. Without the need for multiple manual adjustments and calibrations of the cleaning structure, the cleaning mechanism can complete the cleaning of the remaining tobacco leaves inside the tobacco box.

[0019] After the cleaning mechanism has cleaned the tobacco leaves attached to the tobacco box, the second sensor temporarily releases its monitoring and driving of the tobacco box tilting mechanism and the cleaning mechanism. The driving component drives the tobacco box tilting mechanism to rotate counterclockwise to the starting position, waiting to clamp and tilt the next tobacco box containing tobacco leaves. At the same time, the cleaning end of the cleaning mechanism exits from inside the tobacco box, completing the process of sending the dried tobacco leaves to the processing station on the tobacco leaf conveying assembly for initial processing.

[0020] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0021] 1. In this utility model, the second sensor is connected to the drive component (drive component: flipping motor) of the tobacco box flipping mechanism via a PLC controller. The cleaning mechanism is also connected to the second sensor via a PLC controller. During the flipping process of the tobacco box flipping mechanism, which holds the tobacco box (tobacco box: a box containing tobacco leaves), the second sensor is located on the inner wall of a support arm corresponding to the position where the flipping mechanism needs to flip the tobacco box for both cleaning and tobacco feeding. When the flipping mechanism detects the flipping of the tobacco box, the second sensor simultaneously controls the drive component of the tobacco box flipping mechanism to stop driving via the PLC controller. As the tobacco leaves in the box are tilted, they slide down into the tobacco conveying assembly. The conveying assembly then transports the fallen leaves to various processing stations on the tobacco processing production line for initial processing. Meanwhile, a second sensor controls the cleaning mechanism via a PLC controller. The cleaning end of the cleaning mechanism extends into the empty tobacco box to clean the leaves adhering to the bottom. The cleaned leaves then slide onto the conveying assembly, which continues to transport them to the processing stations for initial processing. Without the need for multiple manual adjustments and calibrations, the cleaning mechanism can complete the cleaning of residual tobacco leaves inside the tobacco box.

[0022] 2. This utility model uses a first sensor connected to a PLC controller and a drive component that drives the tobacco box turning mechanism. The first sensor is located on the tobacco box turning mechanism near the discharge end of the tobacco box conveying assembly. When the tobacco box containing tobacco leaves reaches the tobacco box turning mechanism, the first sensor on the tobacco box turning mechanism will detect that the tobacco box containing tobacco leaves has arrived. Then, the PLC controller controls the drive component that drives the tobacco box turning mechanism to turn, thereby driving the tobacco box turning mechanism that holds the tobacco box (tobacco box: tobacco box containing tobacco leaves) to turn. The tobacco box containing tobacco leaves can be automatically turned by manually pressing the button that controls the turning mechanism.

[0023] 3. This utility model has a connecting plate connected between the frames on one of the inner side walls of the "door"-shaped tilting frame. The inner side walls of the connecting plate are respectively connected to the fixed end of the cylinder, and the driving end of the cylinder is respectively connected to the side wall of the clamping plate. When clamping tobacco boxes containing tobacco leaves that have entered the "door"-shaped tilting frame, the cylinder can drive the clamping plate to clamp tobacco boxes of different widths in the "door"-shaped tilting frame according to the different specifications of the tobacco boxes, thereby further improving the practicality of the tilting and feeding device.

Detailed Implementation

[0033] like Figure 1-8 As shown, to make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] Example

[0035] The cooperation between the tobacco box tilting mechanism and the tobacco box cleaning mechanism can also complete the process of removing the tobacco leaves attached to the bottom of the tobacco box. However, in the actual cleaning process, the following defects still exist: When the tobacco box tilting mechanism tilts the tobacco box, it is often necessary to manually adjust and calibrate it repeatedly before the tobacco box cleaning mechanism can complete the process of cleaning the attached tobacco leaves. This not only reduces the efficiency of cleaning the attached tobacco leaves, but also increases the labor intensity of manual labor.

[0036] Therefore, this application proposes a box-turning feeding device to solve the problem that when cleaning residual tobacco leaves inside the tobacco box, the box-turning mechanism cannot be turned to the optimal angle for the cleaning mechanism to operate, and manual adjustment and calibration are still required multiple times before the cleaning mechanism can complete the cleaning of residual tobacco leaves inside the tobacco box.

[0037] For details, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 A tobacco box tipping and feeding device includes a tobacco box conveying assembly 1, a tobacco box tipping mechanism 2, a tobacco leaf conveying assembly 3, and a cleaning mechanism 4. The tobacco box tipping mechanism 2 is located at the discharge end of the tobacco box conveying assembly 1. A first sensor 28 and a second sensor 19 are electrically connected to a drive component 9 that drives the tobacco box tipping mechanism 2 to tip via a PLC controller. The first sensor 28 is located on the tobacco box tipping mechanism 2 near the discharge end of the tobacco box conveying assembly 1 and is used to monitor whether the tobacco box carrying tobacco leaves has entered the tobacco box tipping mechanism 2. The second sensor 19 is located on the inner wall of a support arm 8 in the tobacco box tipping mechanism 2 that is used to connect a portion of the tobacco box tipping mechanism 2 to rotation and is used to monitor whether the tobacco box tipping mechanism 2 has tipped into place. The discharge end of the tobacco box tipping mechanism 2 is connected to the feed end of the tobacco leaf conveying assembly 3. The cleaning end of the cleaning mechanism 4 is located above the connection between the feed end of the tobacco leaf conveying assembly 3 and the discharge end of the tobacco box tipping mechanism 2. The cleaning mechanism 4 is located on one side of the tobacco leaf conveying assembly 3 and is also electrically connected to the second sensor 19 via a PLC controller.

[0038] In practical applications, when the dried tobacco leaves are conveyed to the processing station on the tobacco leaf conveying assembly 3 for initial processing, the dried tobacco leaves are loaded into the tobacco box on the tobacco box conveying component 3. The tobacco box conveying component 3 conveys the tobacco box containing the dried tobacco leaves to the tobacco box turning mechanism 2, which clamps and locks the tobacco box containing the tobacco leaves. At the same time, the first sensor 28 on the tobacco box turning mechanism 2 detects that the tobacco box is in place. The first sensor 28 then controls the drive component 9 that drives the tobacco box turning mechanism 2 to turn through the PLC controller. The drive component 9 then drives the tobacco box turning mechanism 2 to rotate the clamped tobacco box clockwise.

[0039] When the tobacco box is flipped to the second sensor 19 on the tobacco box flipping mechanism 2 and detected, the tobacco box flipping mechanism 2 flips the tobacco box to a position that is convenient for cleaning and dumping tobacco leaves. The second sensor 19 controls the drive component 9 that drives the tobacco box flipping mechanism 2 to stop driving through the PLC controller. The tobacco leaves in the tobacco box slide from the tilted tobacco box into the tobacco leaf conveying assembly 3. Then, the tobacco leaf conveying assembly 3 transports the fallen tobacco leaves to each processing station on the tobacco processing production line for initial processing. At the same time, the second sensor 19 controls the cleaning mechanism 4 to operate through the PLC controller. The cleaning end of the cleaning mechanism 4 extends into the inside of the tobacco box after the tobacco leaves have been dumped to clean the tobacco leaves attached to the bottom of the tobacco box. The cleaned tobacco leaves slide onto the tobacco leaf conveying assembly 3 and continue to be transported to each processing station for initial processing. The cleaning mechanism can complete the cleaning of the remaining tobacco leaves inside the tobacco box without the need for multiple adjustments and calibrations by the cleaning structure operator.

[0040] After the cleaning mechanism 4 has cleaned the tobacco leaves attached to the tobacco box, the second sensor 19 temporarily releases the monitoring and driving of the tobacco box turning mechanism 2 and the cleaning mechanism 4. The driving component drives the tobacco box turning mechanism 2 to rotate counterclockwise to the starting position, waiting to clamp and turn the next tobacco box containing tobacco leaves. At the same time, the cleaning end of the cleaning mechanism 4 exits from the inside of the tobacco box, completing the process of sending the dried tobacco leaves to the processing station on the tobacco leaf conveying assembly for initial processing.

[0041] It should be noted that there is a certain interval between the cleaning end of the cleaning mechanism 4 entering the tobacco box and the tobacco leaves in the tobacco box being emptied. That is, the cleaning end of the cleaning mechanism 4 enters the tobacco box only after the tobacco leaves in the tobacco box have been emptied.

[0042] Please see Figure 1 , Figure 3 and Figure 4 During the initial processing of the dried tobacco leaves at the processing station on the tobacco leaf conveying assembly 3, the tobacco box conveying assembly 1, which is used to transport the tobacco box containing the dried tobacco leaves to the tobacco box turning mechanism 2, includes a first conveying support 5 and a roller conveyor 6; wherein, the first conveying support 5 is used to support the roller conveyor 6; and the roller conveyor 6 is used to convey the tobacco box containing the dried tobacco leaves.

[0043] Specifically, two roller conveyors 6 are connected between the two first conveying supports 5 respectively, with a gap 7 between the two roller conveyors 6, and a smoke box turning mechanism 2 is set between the discharge ends of the two roller conveyors 6.

[0044] In practical application, when the tobacco box containing dried tobacco leaves is conveyed to the tobacco box turning mechanism 2 by the tobacco leaf conveying assembly 3, the tobacco box containing dried tobacco leaves is placed at the starting end of the two roller conveyor 6. The two roller conveyor 6 then conveys the tobacco box to the discharge end of the two roller conveyor 6, that is, the working position of the tobacco box turning mechanism 2. This makes it easier for the subsequent turning mechanism 2 to clamp the tobacco box containing dried tobacco leaves.

[0045] It should be noted that the roller conveyor 6 is a small automatic conveyor 6. The small automatic conveyor is existing technology and has not been improved or designed. Therefore, its structure will not be described in detail. In the small roller conveyor, the roller protrudes from the upper surface of the conveyor frame that is rotatably connected to the roller.

[0046] Please see Figure 1 and Figure 4 During the initial processing of the dried tobacco leaves at the processing station on the tobacco leaf conveying assembly 3, the tobacco box turning mechanism 2, which is used to clamp and turn the tobacco box containing the tobacco leaves, includes a support arm 8 and a tobacco box clamp 10. The support arm 8 is connected to the conveying frame 11 of the roller conveyor 6 on one hand, and is rotatably connected to the tobacco box clamp 10 on the other hand. The tobacco box clamp 10 is used to clamp the tobacco box containing the tobacco leaves.

[0047] Specifically, the bottom of the support arm 8 is connected to the top of the conveying frame 11 of the two roller conveyors 6, the drive component 9 is rotatably connected to the two support arms 8, the drive component 9 is sleeved with the through hole at one end of the L-shaped connecting rod 12, and the other end of the L-shaped connecting rod 12 is connected to the bottom of the cigarette box clamp 10.

[0048] In practical applications, when the tobacco box turning mechanism 2 clamps and turns the tobacco box containing tobacco leaves that is transported to the station of the tobacco box turning mechanism 2, the tobacco box clamp 10 first clamps the tobacco box that has been transported to the station, and then drives the tobacco box clamp 10 to turn the clamped tobacco box through the drive component 9, so that the tobacco leaves slide from the tobacco box to the tobacco leaf conveying assembly 3, which facilitates the subsequent processing station on the tobacco leaf conveying assembly 3 to perform initial processing on the tobacco leaves.

[0049] Please see Figure 1 and Figure 5 During the process of the tobacco box flipping mechanism 2 clamping and flipping the tobacco box containing tobacco leaves, the driving component 9 used to drive the tobacco box flipping mechanism 2 to flip includes a flipping drive shaft 13 and a flipping drive component 14; wherein, the flipping drive shaft 13 is used to connect with the tobacco box clamp 10 that clamps the tobacco box; the flipping drive component 14 is used to drive the flipping drive shaft 13 to rotate, indirectly driving the tobacco box clamp 10 connected to the flipping drive shaft 13 to rotate, so that the tobacco box is flipped to a suitable cleaning position and tobacco leaf feeding position.

[0050] Specifically, the flipping drive 14 is connected to the side wall of one of the support arms 8. The output shaft of the flipping drive 14 is rotatably connected to the side wall of one of the support arms 8. One end of the flipping drive shaft 13 located between the two support arms 8 is connected to the output shaft of the flipping drive 14. Both ends of the flipping drive shaft 13 are rotatably connected to the two support arms 8 respectively. That is, the output shaft of the flipping drive 14 and the flipping drive shaft 13 between the two support arms 8 are on the same axis and connected to each other. The flipping drive shaft 13 is sleeved with the through hole at one end of the L-shaped connecting rod 12. The other end of the L-shaped connecting rod 12 is connected to the bottom of the cigarette box clamp 10. A gap is left between the L-shaped connecting rod 12 and the support arm 8.

[0051] In practical applications, when the flipping drive 14 drives the tobacco box clamp 10 holding the tobacco box (tobacco box: a tobacco box containing tobacco leaves) to flip, the flipping drive 14 is driven, and the flipping drive 14 drives the tobacco box clamp 10 connected to the flipping drive shaft 13 to rotate accordingly, so that the tobacco box held on the tobacco box clamp 10 is flipped to the position actually required by the tobacco box.

[0052] It should be noted that the flipping drive component 14 is the flipping motor 20.

[0053] Please see Figure 1 , Figure 5 and Figure 6 During the process of the tobacco box flipping mechanism 2 clamping the tobacco box containing tobacco leaves, the tobacco box clamping fixture 10 that clamps the tobacco box containing tobacco leaves includes a "door" shaped flipping frame 15, a cylinder 16, and a clamping plate 17. The "door" shaped flipping frame 15 is used to connect to the drive flipping drive shaft 13 through an L-shaped connecting rod 12, and the "door" shaped flipping frame 15 serves as the basic frame for mounting the cylinder 16. The cylinder 16 is used to drive the clamping plate 17 to clamp the tobacco box containing tobacco leaves that has been transported between the clamping plates 17, thus facilitating the subsequent flipping of the clamped tobacco box.

[0054] Specifically, the bottom of the "door" shaped flip frame 15 is connected to one end of the L-shaped connecting rod 12, and a connecting plate 18 is connected between the frames on one of the inner side walls of the "door" shaped flip frame 15. The inner side walls of the connecting plate 18 are respectively connected to the fixed end of the cylinder 16, and the driving end of the cylinder 16 is respectively connected to the side wall of the clamping plate 17.

[0055] In practical application, when the cigarette box clamp 10 clamps the cigarette box conveyed to the cigarette box flipping mechanism 2, it can drive the cylinder 16. The cylinder 16 then drives the two clamping plates 17 to move towards each other, clamping the cigarette box containing tobacco leaves located between the two clamping plates 17, thus completing the process of clamping the cigarette box conveyed to the cigarette box flipping mechanism 2. This facilitates the subsequent flipping of the clamped cigarette box.

[0056] It should be noted that the clamping plate 1 is a clamping plate with a buffer function. The specific structure of the clamping plate 17 is as follows: the clamping plate 17 is a rectangular structure, and a rectangular rubber pad is attached to the clamping surface of the rectangular clamping plate 17. The cigarette box clamped by the clamping plate 17 is a rectangular cavity structure with an opening at the top, and its material is wood.

[0057] Please see Figure 5 and Figure 6 When the cigarette box clamp 10 holding the cigarette box is flipped, a first sensor 28 for monitoring and controlling the flipping of the cigarette box clamp is set on the lower half of one inner side wall of the "door" shaped flipping frame 15, and a second sensor 19 for monitoring and controlling the flipping of the cigarette box clamp is set on one side of the upper half of the inner side wall of one of the support arms 8. The second sensor 19 and the first sensor 28 are electrically connected to the flipping motor 20 through the PLC controller.

[0058] It should be noted that both the first sensor 28 and the second sensor 19 are existing technologies. The first sensor 28 can be a limit sensor, and the second sensor 19 can be a photoelectric sensor. The first sensor 28 and the second sensor 19 can also be other types of sensors.

[0059] Please see Figure 1 and Figure 7 During the initial processing of the dried tobacco leaves, the tobacco leaf conveying assembly 3 is used to receive the tobacco leaves that slide down from the tobacco box after being flipped by the tobacco box clamp 10. The tobacco leaf conveying assembly 3 includes a feeding bin 21 and a conveyor 23. The feeding bin 21 is a transition component for the tobacco leaves to slide down from the tobacco box onto the conveyor 23. The belt conveyor 23 is used to transport the falling tobacco leaves.

[0060] Specifically, the feeding end of the feeding bin 21 is located on one side of the "gate"-shaped tilting frame 15. The outer wall of the feeding bin 21 is connected to the second conveyor frame 22 in the conveyor 23 through the support frame. The discharging end of the feeding bin 21 is located directly above the feeding end of the belt conveyor 23. There is a certain gap between the discharging end of the feeding bin 21 and the feeding end of the conveyor 23.

[0061] In practical applications, after the tobacco box containing tobacco leaves is flipped by the tobacco box flipping mechanism 2, the tobacco leaves slide from the tobacco box to the tobacco leaf conveying assembly 3. The sliding tobacco leaves first fall orderly onto the conveyor 23 through the feeding bin 21, and then the conveyor 23 transports the tobacco leaves to each processing station for initial processing.

[0062] It should be noted that the conveyor 23 is a belt conveyor 23. Belt conveyors 23 are existing technology and have not been improved or designed. Therefore, their structure will not be described in detail.

[0063] Please see Figure 1 , Figure 7and Figure 8 The cleaning mechanism 4 for cleaning tobacco leaves attached to the inside of the tobacco box includes a support frame 24, a linear slide module 25, a cleaning robotic arm 26, and a cleaning brush 27. The support frame 24 serves as the mounting frame for the linear slide module 25. The linear slide module 25 drives the cleaning robotic arm 26 and the cleaning brush 27 connected to the cleaning robotic arm 26 to move horizontally. The cleaning brush 27 is used to scrape the tobacco leaves attached to the inside of the tobacco box. The cleaning robotic arm 26 is used to adjust the vertical placement angle of the cleaning brush 27.

[0064] Specifically, the support frame 24 is located on one side of the feeding end of the second conveyor frame 22. The support frame 24 is connected to the outer wall of the linear slide module 25. The moving end of the linear slide module 25 is connected to the cleaning robot arm 26. The execution end of the cleaning robot arm 26 is connected to the cleaning brush 27. The cleaning brush 27 is located above the connection between the feeding end of the feeding bin 21 and the discharge end of the "door" shaped tilting frame 15.

[0065] In practical applications, when the cleaning mechanism 4 cleans the tobacco leaves inside the flipped tobacco box, the tobacco box can be flipped to a position that is easy to clean and easy to unload by the tobacco box flipping mechanism 2. The linear slide module 25 drives the cleaning brush 27 connected to the cleaning robot arm 26 to move into the tobacco box to clean the tobacco leaves attached to the tobacco box. After cleaning, the tobacco leaves attached to the tobacco box fall off and fall onto the conveyor 23 through the feeding bin 21.

[0066] It should be noted that the cleaning robot arm 26 is existing technology and has not been improved or designed, so its structure will not be described in detail. The cleaning robot arm 26 is composed of sequentially connected joints, and motors are provided at each joint connection point to adjust the rotation angle of each joint.

[0067] It should be noted that the linear slide module 25 is a lead screw linear slide module with a motor. The aforementioned support frame 24 is connected to the outer wall of the linear slide module 25, that is, the support frame 24 is connected to the base side wall of the lead screw linear slide module. The aforementioned moving end of the linear slide module 25 is connected to the cleaning robot arm 26, that is, the slider in the linear slide module 25 that is threaded with the lead screw is connected to the cleaning robot arm 26. The aforementioned cleaning mechanism 4 is also electrically connected to the second sensor 19 through a PLC controller, that is, the motor on the linear slide module 25 in the cleaning mechanism 4 is electrically connected to the second sensor 19 through a PLC controller.

[0068] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
