Description

Technical Field

[0001] The present application relates to the technical field of tobacco leaf processing equipment, and in particular to a tobacco leaf impurity removal device. Background Art

[0002] The tobacco industry occupies an important position in China's agricultural economy. Its various production links are gradually being mechanized and automated. When processing tobacco leaves, it is necessary to remove impurities mixed in the tobacco leaves. Tobacco leaves are generally mixed with dust, debris, fragments, etc.

[0003] The existing tobacco dust removal method is to place the tobacco leaves on a transmission chain with sieve holes, and then drive the transmission chain to vibrate to separate the impurities in the tobacco leaves from the tobacco leaves. However, the larger fragments are difficult to separate from the tobacco leaves through the sieve holes, resulting in poor tobacco dust removal effect. Summary of the invention

[0004] In order to improve the problem that it is difficult to separate the fragments from the tobacco leaves only through the sieve holes, resulting in poor tobacco impurity removal effect, the present application provides a tobacco impurity removal device.

[0005] The tobacco leaf impurity removal equipment provided in this application adopts the following technical solution: A tobacco impurity removal device comprises a dust removal component, a slag removal component, a conveying and moving component, a visual picking component and a material storage box. The tobacco leaves are sequentially transferred to the conveying and moving component through the dust removal component and the slag removal component. The conveying and moving component can convey the tobacco leaves to the visual picking component. The dust removal component can separate dust from the tobacco leaves. The slag removal component can separate slag from the tobacco leaves. The visual picking component can pick up fragments in the tobacco leaves and put them into the material storage box to separate the tobacco leaves from the fragments.

[0006] By adopting the above technical scheme, when removing impurities from tobacco leaves, the tobacco leaves pass through the dust removal component to remove dust, then pass through the slag removal component to remove debris, and then transfer to the conveying moving component. The conveying moving component transports the tobacco leaves to the visual picking component, and the visual picking component picks the fragments in the tobacco leaves into the material holding box. The picked tobacco leaves are transported to the subsequent process, thereby completing the removal of impurities in the tobacco leaves. Compared with the method of using sieve holes to remove impurities from tobacco leaves, this scheme can separate dust, debris, and fragments from tobacco leaves, thereby improving the impurity removal effect of tobacco leaves.

[0007] In a specific feasible implementation scheme, the visual picking component includes a visual image acquisition and processing module and an execution module. A sorting space is formed at the end of the conveying moving component. The execution module is arranged at the sorting space and is located above the material holding box. The conveying moving component can drive tobacco leaves and fragments into the sorting space so that the tobacco leaves and fragments are vacant in the sorting space. The visual image acquisition and processing module can perform image acquisition and processing on the tobacco leaves and fragments, and control the execution module to drive the fragments to fall into the material holding box.

[0008] By adopting the above technical solution, when separating the fragments, the conveying moving component conveys the tobacco leaves to the sorting space, so that the tobacco leaves and the fragments are vacant in the sorting space for a period of time, and then the visual image acquisition and processing module performs image acquisition and processing on the tobacco leaves and the fragments, and controls the execution module to transfer the fragments to the material holding box, thereby completing the separation of the fragments and the tobacco leaves and improving the impurity removal effect of the tobacco leaves.

[0009] In a specific feasible implementation scheme, the execution module includes a gas delivery pipe of an external high-pressure gas generating device and a plurality of nozzles, the gas delivery pipe is arranged in the sorting space, the plurality of nozzles are arranged on the gas delivery pipe and are arranged opposite to the top opening of the material holding box, and the plurality of nozzles are arranged along the width direction of the conveying moving component so as to be able to blow fragments at different positions into the material holding box.

[0010] By adopting the above technical solution, when the fragments are transferred, the image acquisition and processing module controls the nozzle at the fragment to open, and the high-pressure gas ejected from the nozzle blows the fragments into the material holding box, thereby completing the separation of the fragments and improving the accuracy and convenience of fragment separation.

[0011] In a specific possible implementation scheme, the material holding box includes two storage boxes arranged opposite to each other, and a support plate for supporting the two storage boxes is provided on the shell, and the two storage boxes can slide on the support plate, and handles are provided on opposite sides of the storage boxes so that the two storage boxes can be pulled out from both sides of the shell respectively.

[0012] By adopting the above technical solution, when cleaning the impurities in the storage box, the staff can pull out the two storage boxes from the two sides of the shell by the handles, effectively avoiding the problem of inconvenience in cleaning impurities due to the length of the storage box, and improving the convenience of cleaning impurities in the storage box.

[0013] In a specific possible implementation scheme, a push plate is slidably provided in each storage box, a driving rod is slidably provided through the side wall of the storage box, and the driving rod is fixedly connected to the push plate to drive the push plate to slide in the storage box.

[0014] By adopting the above technical solution, as impurities fall into the storage box, the operator drives the push plate to slide in the storage box through the driving rod to level the accumulated impurities, thereby increasing the storage box's capacity to hold impurities.

[0015] In a specific possible implementation scheme, the dust removal assembly includes a guide drop barrel, a suction pipe and an exhaust piece. The guide drop barrel is arranged above the conveying moving assembly to guide the tobacco leaves to fall onto the conveying moving assembly. One end of the suction pipe is connected to the guide drop barrel, and the other end is connected to the exhaust piece so that the exhaust piece can extract the dust in the guide drop barrel.

[0016] By adopting the above technical solution, the tobacco leaves are poured into the guiding barrel. When the tobacco leaves collide with each other in the guiding barrel, dust is raised. The exhaust member sucks the dust generated in the guiding barrel out of the guiding barrel through the suction tube, thereby completing the separation of the tobacco leaves and the dust.

[0017] In a specific possible implementation scheme, the slag removal assembly includes a swinging drive, a debris collecting member and a debris removal screen. The debris removal screen is rotatably arranged in the guide drop barrel so that the debris removal screen can swing in a vertical plane. The debris collecting member is arranged below the debris removal screen and can receive the debris dropped from the debris removal screen. The swinging drive is used to drive the debris removal screen to swing.

[0018] By adopting the above technical solution, as the tobacco leaves fall, the swinging driving part drives the impurity removal screen to swing in the guiding barrel, hitting the falling tobacco leaves. After the collision, the debris falls into the debris collecting part for collection, thereby realizing the separation of the debris and the tobacco leaves, effectively preventing the debris from entering between the tobacco leaves on the conveying moving component, and improving the separation effect of the debris and the tobacco leaves; when the impurity removal screen hits the tobacco leaves, the dust attached to the tobacco leaves is knocked off, so that the tobacco leaves and the dust are separated more thoroughly.

[0019] In a specific possible implementation scheme, there are two of the debris collecting pieces and two of the impurity removal screens, and the debris collecting pieces correspond to the impurity removal screens one by one. The two impurity removal screens are arranged on the opposite side walls of the guide barrel, and the two impurity removal screens are spaced apart in the vertical direction so as to form a flow channel for tobacco leaves to pass through between the two impurity removal screens.

[0020] By adopting the above technical solution, the tobacco leaves are beaten by two impurity removal screens during their falling process, which can increase the probability of the impurity removal screens contacting the tobacco leaves, thereby improving the effect of separating dust from tobacco leaves and collecting debris.

[0021] In a specific possible implementation manner, each of the impurity removal screens is rotatably connected to the guide drop barrel via a rotating shaft; The driving member includes a driving wheel, a driving spring and a motor transmission mechanism. The driving wheel corresponds to the impurity removal screen one by one and is rotatably arranged on the shell. A swing rod is fixedly provided on the rotating shaft. The swing rod and the shell are connected through the driving spring. A pressure rod is provided on the driving wheel. The pressure rod can squeeze the swing rod to make the driving spring contract. The driving spring can push the swing rod to reset so that the impurity removal screen can swing. The motor transmission mechanism is used to drive the two driving wheels to rotate.

[0022] By adopting the above technical solution, when the impurity removing screen is driven to swing, the motor transmission mechanism drives the driving wheel to rotate, and the driving wheel drives the pressure rod to press down the swing rod, so that the impurity removing screen produces unidirectional rotation. At this time, the driving spring contracts, and when the pressure rod is disengaged from the swing rod, the driving spring drives the swing rod to reset, so that the impurity removing screen produces bidirectional swing, thereby realizing the driving of the impurity removing screen to swing.

[0023] In a specific feasible implementation scheme, the debris collection member includes a collection plate and a conveying auger. The collection plate is fixedly arranged on the wall of the guide barrel and is located below the impurity removal screen. The lowest end of the collection plate forms an arc surface cooperating with the conveying auger. The conveying auger is rotatably arranged at the lowest end of the collection plate. A discharge port is provided on the guide barrel, and the conveying auger can transport the debris to the discharge port.

[0024] By adopting the above technical solution, the debris that falls onto the collecting plate through the impurity removal screen is gathered at the lowest end of the collecting plate. The gathered debris is transported to the discharge port through the rotation of the conveying auger and discharged from the discharge port, thereby improving the convenience of debris cleaning.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. When removing impurities from tobacco leaves, the tobacco leaves are passed through the dust removal component to remove dust, and then through the slag removal component to remove slag, and then transferred to the conveying moving component. The conveying moving component conveys the tobacco leaves to the visual picking component, and the visual picking component picks the fragments in the tobacco leaves into the material storage box. The picked tobacco leaves are conveyed to the subsequent process, thereby completing the removal of impurities in the tobacco leaves. Compared with the method of using sieve holes to remove impurities from tobacco leaves, this solution can separate dust, slag, fragments and tobacco leaves, thereby improving the impurity removal effect of tobacco leaves; 2. When cleaning the impurities in the storage box, the staff can pull out the two storage boxes from both sides of the shell by the handle, which effectively avoids the problem of inconvenience in cleaning impurities due to the length of the storage box, and improves the convenience of cleaning impurities in the storage box; 3. As the tobacco leaves fall, the swing drive drives the impurity removal screen to swing in the guide drop barrel and hit the falling tobacco leaves.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-9 This application is described in further detail.

[0037] The embodiment of the present application discloses a tobacco leaf impurity removal device.

[0038] Reference Figure 1 A tobacco leaf impurity removal device includes a housing 1, a dust removal component 2, a slag removal component 3, a conveying and moving component 4, a visual picking component 5, and a material storage box 6. The impurity removal path of the tobacco leaves is first transferred to the conveying and moving component 4 through the dust removal component 2 and the slag removal component 3, and then the conveying and moving component 4 can transport the tobacco leaves to the visual picking component 5. The housing 1 is provided with a drop port 11 downstream of the visual picking component 5. The tobacco leaves processed by the visual picking component 5 enter the next processing process through the drop port 11. The dust removal component 2 can separate dust from tobacco leaves, the slag removal component 3 can separate slag from tobacco leaves, and the visual picking component 5 can pick the fragments in the tobacco leaves into the material storage box 6 to separate the tobacco leaves from the fragments.

[0039] When removing impurities from tobacco leaves, the tobacco leaves are first poured into the dust removal component 2, the dust is removed by the dust removal component 2, the slag is removed by the slag removal component 3, and then the leaves are transferred to the conveying moving component 4. The conveying moving component 4 conveys the tobacco leaves to the visual picking component 5, and the visual picking component 5 picks the fragments in the tobacco leaves into the material holding box 6. The picked tobacco leaves are conveyed to the subsequent process, thereby completing the removal of impurities in the tobacco leaves. Compared with the method of using sieve holes to remove impurities from tobacco leaves, this solution can separate dust, slag, fragments and tobacco leaves, thereby improving the impurity removal effect of tobacco leaves.

[0040] Reference Figure 2The dust removal assembly 2 in this embodiment includes a guide barrel 21, a suction pipe 22 and an exhaust member 23. The guide barrel 21 is fixedly arranged on the housing 1 along the vertical direction. The top of the guide barrel 21 forms a flared opening to facilitate the feeding of tobacco leaves. The bottom outlet of the guide barrel 21 is arranged above one end of the conveying and moving assembly 4, so that the tobacco leaves dropped from the guide barrel 21 fall onto the conveying and moving assembly 4. One end of the suction pipe 22 is connected to the guide barrel 21, and the other end is connected to the exhaust member 23, and a filter box 24 is connected in series on the suction pipe 22. The exhaust member 23 in this embodiment is an exhaust fan, and the exhaust fan sucks dust into the filter box 24 through the suction pipe 22 for filtering. The suction pipe 22 is equipped with a shielding net 25 at the suction port in the guide barrel 21 to effectively prevent the suction pipe 22 from sucking tobacco leaves into the suction pipe 22.

[0041] The tobacco leaves are poured into the guide barrel 21. When the tobacco leaves collide with each other in the guide barrel 21, dust is raised. The exhaust fan sucks the dust generated in the guide barrel 21 out of the guide barrel 21 through the suction pipe 22, thereby completing the separation of the tobacco leaves and the dust.

[0042] Reference Figure 3 The slag removal assembly 3 in this embodiment includes a swing driving member 31, a slag collecting member 32 and a dust removing screen 33. The number of the slag collecting member 32 and the dust removing screen 33 are both two, and they correspond one to one. The two dust removing screens 33 are respectively arranged on the opposite side walls of the guide barrel 21. The two dust removing screens 33 are arranged at intervals along the vertical direction, so that a flow channel 34 for tobacco leaves to pass through is formed between the two dust removing screens 33. A rotating shaft 35 is fixed on both sides of one end of each dust removing screen 33 close to the corresponding guide barrel 21. The rotating shaft 35 passes through the side wall of the guide barrel 21 and is rotatably connected to the guide barrel 21.

[0043] The swing driving member 31 in this embodiment includes a driving wheel 311, a driving spring 312 and a motor transmission mechanism 313. The driving wheel 311 corresponds to the rotating shaft 35 one by one and is rotatably arranged on the outer wall of the guiding blanking barrel 21 through a support shaft. A swing rod 314 is fixedly arranged on one end of each rotating shaft 35 passing through the guiding blanking barrel 21. A guide rod 315 is fixedly arranged on the outer wall of the guiding blanking barrel 21. The guide rod 315 is circumferentially arranged with a circle with the axis of the rotating shaft 35 as the center. The rod 315 is slidably inserted into the swing rod 314, and a support block 316 is provided on the guide rod 315. The driving spring 312 is sleeved on the guide rod 315 and is located between the support block 316 and the swing rod 314. One end of the driving spring 312 is fixedly connected to the support block 316, and the other end is fixedly connected to the swing rod 314. When the swing rod 314 rotates, the driving spring 312 can be pressed down to contract. When the driving spring 312 is in a stable state, the two impurity removing screens 33 are both tilted downward.

[0044] A plurality of pressure rods 317 are provided on the driving wheel 311, and the number of pressure rods 317 can affect the swinging frequency of the impurity removing screen 33. In this embodiment, three pressure rods 317 are taken as an example, and the three pressure rods 317 are evenly arranged along the circumference of the driving wheel 311. The sum of the lengths of the pressure rods 317 and the swing rod 314 is greater than the distance between the center of the rotating shaft 35 and the center of the driving wheel 311. When the driving wheel 311 drives the pressure rod 317 to rotate, the pressure rod 317 presses down the swing rod 314 to rotate, and the driving spring 312 contracts at this time. As the driving wheel 311 continues to rotate, the pressure rod 317 disengages from the swing rod 314, and the driving spring 312 pushes the swing rod 314 to reset, so that the impurity removing screen 33 produces a bidirectional swing to realize the driving of the impurity removing screen 33 to swing.

[0045] Reference Figure 4 The motor transmission mechanism 313 in this embodiment includes a driving motor 3131 and a transmission chain 3132. Each driving wheel 311 is a sprocket. The pressure rod 317 is arranged on the side of the driving wheel 311. The driving motor 3131 is fixedly arranged on the side wall of the guiding blanking barrel 21, and a driving sprocket is coaxially fixed on its output shaft. The transmission chain 3132 bypasses the two driving wheels 311 and the driving sprockets in turn, thereby realizing the driving of the two driving wheels 311.

[0046] Reference Figure 5 The debris collecting member 32 in this embodiment includes a collecting plate 321 and a conveying auger 322. One end of the collecting plate 321 is fixedly arranged on the wall of the guide barrel 21 and is located below the impurity removal screen 33. The collecting plate 321 and the end of the impurity removal screen 33 are connected by an elastic cloth 324 to prevent tobacco leaves from entering the collecting plate 321. The inclination angle of the collecting plate 321 is the same as the inclination angle of the impurity removal screen 33 when it is stationary, and a certain distance is left between the two for the impurity removal screen 33 to swing. The lowest end of the collection tray 321 forms an arc surface that matches the conveying auger 322. The conveying auger 322 is placed horizontally in the guide barrel 21 and driven to rotate by an external motor. The conveying auger 322 is located at the lowest end of the collection tray 321. A discharge port 323 corresponding to the conveying auger 322 is provided on one side of the guide barrel 21. The conveying auger 322 can convey the slag to the discharge port 323, and the slag flows out from the discharge port 323 to complete the discharge of the slag. The slag that falls onto the collection tray 321 by the impurity removal screen 33 is gathered at the lowest end of the collection tray 321. The collected slag is transported to the discharge port 323 through the rotation of the conveying auger 322, and the slag is discharged from the discharge port 323, thereby improving the convenience of cleaning the slag.

[0047] As the tobacco leaves fall, the swing drive member 31 drives the impurity removal screen 33 to swing in the guide drop barrel 21, hitting the falling tobacco leaves. After the collision, the debris falls into the debris collection member 32 for collection, thereby separating the debris from the tobacco leaves, effectively preventing the debris from entering between the tobacco leaves on the conveying moving component 4, and improving the separation effect of the debris from the tobacco leaves; when the impurity removal screen 33 hits the tobacco leaves, the dust attached to the tobacco leaves is knocked off, so that the tobacco leaves and the dust are separated more thoroughly.

[0048] Reference Figure 6 The conveying moving component 4 in this embodiment includes a conveyor belt mechanism 41 and a blocking net 42. The conveyor belt mechanism 41 is horizontally arranged on the shell 1, and the blocking net 42 is arranged above the conveyor belt in the conveyor belt mechanism 41. When tobacco leaves fall onto the conveyor belt mechanism 41, the blocking net 42 blocks the tobacco leaves, so that the thickness of the tobacco leaves on the conveyor belt mechanism 41 can be adjusted, which is convenient for the subsequent picking of fragments in the tobacco leaves.

[0049] The visual picking component 5 in this embodiment includes a visual image acquisition and processing module 51 and an execution module 52 . A sorting space 53 is formed at the end of the conveying moving component 4 . The sorting space 53 is located directly above the material holding box 6 .

[0050] The visual image acquisition and processing module 51 includes a visual camera 511 and an image processing module. The visual camera 511 is used to capture pictures and video information of items. The image processing module is responsible for processing the image information into digital signals and performing image classification and metering operations. Commonly used image processing methods include template matching, neural networks, support vector machines, etc. The execution module 52 is arranged at the sorting space 53 and is located above the material storage box 6. The execution module 52 in this embodiment includes a gas delivery pipe 522 of an external high-pressure gas generating device and a plurality of nozzles 523. The gas delivery pipe 522 is arranged in the sorting space 53, and a plurality of nozzles 523 are arranged on the gas delivery pipe 522 and are arranged relative to the top opening of the material storage box 6. The plurality of nozzles 523 are arranged along the width direction of the conveying moving component 4, and each nozzle 523 is provided with a solenoid valve 524 to control the opening and closing of the nozzle 523. The conveyor belt conveys the tobacco leaves to the sorting space 53, so that the tobacco leaves and fragments are vacant in the sorting space 53 for a period of time, and then the visual image acquisition and processing module 51 acquires and processes images of the tobacco leaves and fragments, and controls the execution module 52 to transfer the fragments to the material box 6, thereby completing the separation of the fragments and the tobacco leaves and improving the impurity removal effect of the tobacco leaves.

[0051] The housing 1 is fixedly provided with a support plate 12 below the material storage box 6, and the material storage box 6 is supported by the support plate 12. The material storage box 6 includes two storage boxes 61 arranged opposite to each other, and the two storage boxes 61 can slide on the support plate 12. A handle 62 is provided on the opposite sides of each storage box 61, and the two storage boxes 61 can be respectively drawn out from the two sides of the housing 1 through the handle 62.

The driving rod 64 is fixedly connected to the push plate 63, and the push plate 63 is driven to slide by the driving rod 64 to push the accumulated impurities to the two sides. When cleaning the impurities in the storage box 61, the staff can pull the two storage boxes 61 out from the two sides of the housing 1 through the handle 62, which effectively avoids the problem of inconvenience in cleaning impurities caused by the excessive length of the material storage box 6, and improves the convenience of cleaning impurities in the storage box 61. As the impurities fall into the storage box 61 , the operator drives the push plate 63 to slide in the storage box 61 through the drive rod 64 to level the accumulated impurities, thereby increasing the storage box 61 's capacity to hold impurities.

[0052] The implementation principle of a tobacco leaf impurity removal device in the embodiment of the present application is as follows: when impurities are removed from tobacco leaves, the tobacco leaves collide with each other in the guide drop barrel 21, raising dust, and the exhaust fan sucks the dust generated in the guide drop barrel 21 out of the guide drop barrel 21 through the suction pipe 22, completing the separation of tobacco leaves and dust. As the tobacco leaves fall, the driving motor 3131 drives the impurity removal screen 33 to swing in the guide drop barrel 21, hitting the falling tobacco leaves, and the debris after the collision falls into the collection plate 321 for collection, thereby achieving the separation of debris and tobacco leaves, and the tobacco leaves fall onto the conveyor belt mechanism 41 The conveyor belt mechanism 41 conveys the tobacco leaves to the sorting space 53, so that the tobacco leaves and fragments are vacant in the sorting space 53 for a period of time, and then the visual image acquisition and processing module 51 acquires and processes images of the tobacco leaves and fragments, and controls the execution module 52 to transfer the fragments to the material holding box 6, thereby completing the separation of the fragments and the tobacco leaves, and the picked tobacco leaves are conveyed to the subsequent process, thereby completing the removal of impurities in the tobacco leaves.
