Description

Technical Field

[0001] The present invention relates to the technical field of tobacco equipment, and more particularly to a tobacco shred back-blending and dumping device and a control method. Background Art

[0002] In the tobacco production process, tobacco backmixing and dumping are crucial links; existing tobacco backmixing and dumping devices generally use a single translation or rotation mechanism to achieve tobacco collection and dumping; although these traditional devices meet the basic tobacco backmixing needs to a certain extent, there are still some problems in actual application, especially in terms of the accuracy and stability of tobacco dumping.

[0003] When existing devices dump tobacco back into the storage silo, it is often difficult to accurately control the position of the collection box; this may result in the tobacco not falling accurately into the designated position of the storage silo, or even scattering outside the equipment, resulting in material waste.

[0004] However, in the back-mixing and pouring process that requires the coordinated completion of multiple actions, existing devices find it difficult to achieve precise synchronization of translation and flipping movements; this may not only cause the collection box to tilt during movement, but may also cause equipment failure and reduce production efficiency; even if precise control can be achieved, the structure is usually more complex and the volume is larger, making it difficult to adapt to the requirements of modern production lines for compact equipment.

[0005] Therefore, how to provide a tobacco re-blending and dumping device that can accurately control the collection box to achieve synchronous translation and flipping movements and has a compact structure is a problem that technical personnel in this field urgently need to solve. Summary of the Invention

[0006] In view of this, the present invention provides a tobacco back-blending and dumping device and a control method, aiming to solve the above technical problems.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A tobacco backblending and dumping device comprises a mounting plate, wherein the mounting plate is provided with two first slide rails arranged in parallel, wherein two first translation brackets are slidably connected to the two first slide rails, wherein one end of the two first translation brackets is fixedly connected via a connecting plate, wherein a first rack is fixed to each of the first translation brackets, wherein a track constraint groove is formed on the inner side of each of the two first translation brackets, and wherein a second slide rail is fixed to the inner top of each of the two first translation brackets;

[0009] A collection box, wherein a turning shaft is fixed on both sides of the collection box, and the two turning shafts are respectively slidably connected to the track constraint grooves on both sides;

[0010] Slider frames, the number of which is two and which are respectively slidably connected to the second slide rail, the two slider frames having through holes for the flip shaft to pass through, and the slider frame away from the first rack being fixedly connected to the second rack;

[0011] The driving mechanism includes a rotatable driving shaft, and gears of different diameters are fixed to both ends of the driving shaft. The two gears are respectively engaged with the first rack and the second rack, so that the movement speed of the second rack is greater than the movement speed of the first rack.

[0012] Through the above technical solution, in a tobacco back-blending and dumping device provided by the present invention, the movement of the first translation bracket and the slider bracket is controlled by the same driving mechanism, thereby achieving synchronous coordination between the two; this synchronization ensures the stability of the collection box during translation and flipping, avoids shaking or jamming caused by asynchrony, and improves the reliability of equipment operation and the accuracy of tobacco dumping; gears of different sizes and diameters are respectively engaged with the first rack and the second rack, so that the movement speed of the second rack is greater than that of the first rack. This differential design enables the slider bracket to achieve a longer linear displacement in the same time. The structure of the first translation bracket forms a first-level telescopic action module, and the slider bracket forms a second-level telescopic action module, so that the structural setting forms a two-stage telescopic structure. Under the control of the driving mechanism, when the second-level telescopic action module is fully extended, the corresponding dumping action is achieved through the guidance of the trajectory constraint groove. At the same time, the structure is set in a relatively compact space and integrates multiple functional components, including slide rails, brackets, racks and gears, etc., which effectively utilizes the installation space of the equipment; this compact design enables the device to adapt to production environments of different scales and improves the versatility of the equipment.

[0013] Preferably, in the above-mentioned tobacco remixing and pouring device, the slider frame includes a slider and a vertical connecting plate. The slider is slidably connected to the second slide rail, the vertical connecting plate is fixed to the slider, and the through hole is provided in the vertical connecting plate. The slider of the slider frame is slidably connected to the second slide rail to ensure smooth movement of the slider frame. The through hole in the vertical connecting plate allows the tilting shaft to pass through, resulting in a compact design and a stable connection.

[0014] Preferably, in the aforementioned tobacco remixing and dumping device, the tip of the flip shaft has an end plate, the outer side of which is rotatably connected to a flip roller, which is disposed within the trajectory constraint groove. The flip roller is connected to the outer side of the end plate at the tip of the flip shaft, and the roller rolls within the trajectory constraint groove, ensuring smooth operation of the flip shaft, reducing friction and wear, and extending the service life of the device.

[0015] Preferably, in the above-mentioned tobacco remixing and dumping device, the trajectory constraint groove is arranged in a Z-shape. The Z-shape arrangement of the trajectory constraint groove allows the collection box to achieve a flipping action during the translation process, adapting to different working conditions and ensuring accurate dumping of the tobacco.

[0016] Preferably, in the above-mentioned tobacco remixing and pouring device, the bend of the trajectory constraint groove is rounded. The bend of the trajectory constraint groove is rounded to reduce stress concentration and improve the durability and reliability of the device.

[0017] Preferably, in the above-mentioned tobacco re-blending and dumping device, the driving mechanism further comprises a driving motor, a support frame, a driven pulley, a driving pulley, and a belt, wherein the driving motor is mounted on the mounting plate, the support frame is mounted on the mounting plate and on a side away from the driving motor, the driving shaft is rotatably connected to the support frame, the driven pulley is sleeved on the outside of the driving shaft, the driving pulley is connected to the power output shaft of the driving motor, and the belt is tensioned between the driving pulley and the driven pulley. The belt drive of the driving mechanism transmits the motor power to the driving shaft, achieving efficient power transmission, and the precise control of the driving motor ensures the synchronous movement of the first translation bracket and the slider frame, achieving precise flipping of the collection box.

[0018] Preferably, in the above-mentioned tobacco remixing and pouring device, a first rack connecting plate is connected between the first rack and the first translation bracket, and a second rack connecting plate is connected between the second rack and the vertical connecting plate. The connection via the rack connecting plate enhances structural stability and ensures smooth movement.

[0019] Preferably, in the above-mentioned tobacco remixing and dumping device, the gear ratio of the two gears is 2:1. This gear ratio setting makes the movement speed of the second rack greater than the movement speed of the first rack, achieving differential translation and ensuring that the collection box can accurately dump the tobacco when it reaches the discharge position.

[0020] Preferably, the above-mentioned tobacco remixing and dumping device further includes a frame, a third slide rail mounted on the frame, the mounting plate being slidably connected to the third slide rail, and the third slide rail being perpendicular to the first slide rail. The third slide rail mounted on the frame provides additional guidance and support for the mounting plate, ensuring smooth sliding of the mounting plate along the length of the frame, thereby improving the stability and reliability of the entire device.

[0021] The present invention also discloses a control method, comprising:

[0022] Initial state: the first translation bracket and the slider frame are in the initial position, and the collection box is in a horizontal state;

[0023] Translation control: The driving mechanism controls the rotation of the driving shaft, thereby driving the first translation bracket to slide along the first slide rail, and at the same time driving the slider frame to slide along the second slide rail, so that the slider frame can achieve a longer linear displacement in the same time;

[0024] Dumping control: When the slider frame is fully extended, the flip axis is guided by the track constraint groove, and as the first translation bracket continues to move, the collection box flips and dumps to complete the discharge;

[0025] Reset control: After the collection box is dumped, the drive mechanism controls the drive shaft to rotate in the opposite direction, thereby driving the first translation bracket and the slider frame to move in the opposite direction. The collection box rotates in the opposite direction driven by the flip shaft and returns to the horizontal state; the collection box and the slider frame return to the initial position, ready for the next back-mixing and dumping operation.

[0026] The present invention also discloses a cut tobacco feeder including the above-mentioned cut tobacco re-blending and dumping device. By integrating the cut tobacco re-blending and dumping device into the cut tobacco feeder, the entire process of cut tobacco re-blending, transportation, and recycling is automated, thereby improving production efficiency and resource utilization.

[0027] It should be noted that the above-mentioned tobacco re-blending and dumping device is not limited to being used in conjunction with a tobacco feeder, but can be used in conjunction with other tobacco equipment involved according to actual needs, and has a wider scope of application.

[0028] It can be seen from the above technical solutions that, compared with the prior art, the present invention provides a tobacco remixing and dumping device and a tobacco feeder, which have the following beneficial effects:

[0029] 1. The present invention controls the movement of the first translation bracket and the slider rack through the same driving mechanism to achieve synchronous coordination between the two, ensuring the stability of the collection box during translation and flipping, and uses gears with different tooth diameters to engage with the first rack and the second rack respectively, so that the movement speed of the second rack is greater than that of the first rack, enabling the slider rack to complete a longer linear displacement in the same time, thereby improving work efficiency; the trajectory constraint groove guides the movement of the flip shaft, ensuring that the collection box can flip along a predetermined trajectory when it reaches the discharge position, thereby achieving precise tobacco dumping.

[0030] 2. The present invention integrates multiple functional components into a relatively small space through a compact design, which facilitates the integration of the device into production environments of different scales. It has strong adaptability and can reduce the requirements for the spatial layout of the production site. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0054] See attached Figure 1 To the attached Figure 8 The embodiment of the present invention discloses a tobacco remixing and dumping device, comprising:

[0055] A mounting plate 1 is provided with two first slide rails 11 arranged in parallel, and two first translation brackets 12 are slidably connected to the two first slide rails 11. One end of the two first translation brackets 12 is fixedly connected by a connecting plate 13. A first rack 14 is fixed to each first translation bracket 12. A track constraint groove 121 is formed on the inner side of each first translation bracket 12. A second slide rail 15 is fixed to the inner top of each first translation bracket 12;

[0056] The collection box 2 has a turning shaft 21 fixed on both sides of the collection box 2. The two turning shafts 21 are slidably connected to the track constraint grooves 121 on both sides respectively;

[0057] There are two slider frames 3, each of which is slidably connected to the second slide rail 15. The two slider frames 3 have a through hole for the flip shaft 21 to pass through. The slider frame 3 away from the first rack 14 is fixedly connected to the second rack 31;

[0058] The driving mechanism 4 includes a rotatable driving shaft 41, and gears 42 of different diameters are fixed at both ends of the driving shaft 41. The two gears 42 are respectively engaged with the first rack 14 and the second rack 31, so that the movement speed of the second rack 31 is greater than the movement speed of the first rack 14.

[0059] like Figure 2 As shown, the gear 42, the first rack 14 and the two first translation brackets 12 on the left form a first translation unit, and the gear 42, the second rack 31 and the slider frame 3 on the right form a second translation unit, which are synchronously driven by the same driving mechanism 4. At the same time, because the number of teeth of the gear 42 on the right is greater than the number of teeth of the gear 42 on the left, the translation speed of the second translation unit is greater than the translation speed of the first translation unit. This structural setting realizes the maximum displacement length within the same time. At the same time, when the second translation unit moves to the end of the maximum stroke, the trajectory constraint groove 121 cooperates with the flip roller 23 and the flip shaft 21 to realize the flipping of the collection box 2, and then realize the dumping action.

[0060] In order to further optimize the above technical solution, the slider frame 3 includes a slider 32 and a vertical connecting plate 33. The slider 32 is slidably connected to the second slide rail 15. The vertical connecting plate 33 is fixed on the slider 32, and a through hole is opened on the vertical connecting plate 33.

[0061] In order to further optimize the above technical solution, the end of the flip shaft 21 has an end plate 22 , and the outer side of the end plate 22 is rotatably connected to a flip roller 23 , which is arranged in the track constraint groove 121 .

[0062] In order to further optimize the above technical solution, the trajectory constraint groove 121 is arranged in a Z shape, such as Figure 4 shown.

[0063] In order to further optimize the above technical solution, the bends of the trajectory constraining groove 121 are rounded.

[0064] In order to further optimize the above technical solution, the driving mechanism 4 also includes a driving motor 43, a support frame 44, a driven pulley 45, a driving pulley 46 and a belt 47. The driving motor 43 is installed on the mounting plate 1, and the support frame 44 is installed on the mounting plate 1 and on the side away from the driving motor 43. The driving shaft 41 is rotatably connected to the support frame 44, the driven pulley 45 is sleeved on the outside of the driving shaft 41, the driving pulley 46 is connected to the power output shaft of the driving motor 43, and the belt 47 is tensioned between the driving pulley 46 and the driven pulley 45.

[0065] In order to further optimize the above technical solution, a first rack connecting plate 16 is connected between the first rack 14 and the first translation bracket 12 ; a second rack connecting plate 34 is connected between the second rack 31 and the vertical connecting plate 33 .

[0066] In order to further optimize the above technical solution, the gear ratio of the two gears 42 is 2:1. As shown in FIG**, the gear ratio of the gear 42 meshing with the second rack 31 and the gear 42 meshing with the first rack 14 is 2:1.

[0067] In order to further optimize the above technical solution, the distances between the first gear 421 and the second gear 422 and the driven pulley are the same.

[0068] In order to further optimize the above technical solution, a rack 5 is further included. A third slide rail 51 is installed on the rack 5. The mounting plate 1 is slidably connected to the third slide rail 51, and the third slide rail 51 is perpendicular to the first slide rail 11.

[0069] A method for controlling a tobacco remixing and dumping device is characterized by comprising:

[0070] Initial state: the first translation bracket 12 and the slider frame 3 are in the initial position, and the collection box 2 is in a horizontal state;

[0071] Translation control: The driving mechanism 4 controls the driving shaft 41 to rotate, thereby driving the first translation bracket 12 to slide along the first slide rail 11, and at the same time driving the slider frame 3 to slide along the second slide rail 15, so that the slider frame 3 can achieve a longer linear displacement within the same range;

[0072] Dumping control: When the slider frame 3 is fully extended, the flip shaft 21 is guided by the track constraint groove 121, and as the first translation bracket 12 continues to move, the collection box 2 is flipped and dumped to complete the discharge;

[0073] Reset control: After the collection box 2 is dumped, the driving mechanism 4 controls the driving shaft 41 to rotate in the opposite direction, thereby driving the first translation bracket 12 and the slider frame 3 to move in the opposite direction. The collection box 2 rotates in the opposite direction under the drive of the flip shaft 21 and returns to the horizontal state; the collection box 2 and the slider frame 3 return to the initial position, preparing for the next backmixing and dumping operation.

[0074] See attached Figure 9-19 The present invention also provides a tobacco feeder; comprising an adjustable tobacco collecting device 6, a storage bin 7, a climbing mechanism 8 and a tobacco back-blending dumping device, such as Figure 6 As shown, one side of the storage bin 7 has a switch door 72 controlled by a cylinder 71. The control end of the cylinder 71 is electrically connected to the control unit. When the collection box 2 is close to the need to be dumped, the control cylinder 71 opens the switch door 72. After the dumping is completed, the control cylinder 71 closes the switch door 72 to ensure that the storage bin 7 is normally closed.

[0075] like Figure 6 As shown, it is a schematic diagram of the tobacco re-blending and dumping device in the receiving state; a linear vibrating screen 9 is installed corresponding to the outlet end of the climbing mechanism 8, and the scattered tobacco is transported to the linear vibrating screen 9 through the climbing mechanism 8. When the tobacco re-blending and dumping device is in the receiving state, it is located directly below the outlet end of the linear vibrating screen 9 to collect the tobacco. Figure 8As shown, it is a schematic diagram of the tobacco back-mixing and dumping device in the state of being ready to be discharged, and the dumping of tobacco inside the collection box 2 is achieved through the first translation bracket 12, the sliding bracket 3 and the driving mechanism 4; specifically: it also includes a controller and a detection element. After the detection element detects that the tobacco has reached the collection threshold, the controller controls the drive motor 43 to start, and drives the drive shaft 41 to rotate through the belt transmission (driving pulley 46, driven pulley 45, belt 47). The gears 42 with different diameters at both ends of the drive shaft are respectively engaged with the first rack 14 and the second rack 31; since the gear ratio of the two gears is 2:1 (the second gear The number of teeth of the gear corresponding to the rack 31 is larger), and the movement speed of the second rack 31 is greater than that of the first rack 14, so that the translation speed of the slider frame 3 along the second slide rail 15 is faster than the translation speed of the first translation bracket 12 along the first slide rail 11. During the translation process, the flip shafts 21 on both sides of the collection box 2 slide in contact with the track constraint groove 121 (arranged in a Z shape) through the flip rollers 23 on the end plate 22; when the slider frame 3 moves to the end of the maximum stroke, the flip roller 23 is guided to move upward or downward along the bending path of the track constraint groove 121, forcing the collection box 2 to flip around the flip shaft 21 (such as Figure 8 After the dumping is completed, the controller controls the reverse drive to reset.

[0076] The adjustable tobacco collecting device 6 is located below the storage bin 5 and includes:

[0077] The bottom box 61 is a U-shaped structure consisting of a mounting plate 611 and two side plates 612. A guide groove 6121 is formed at the end of each side plate 612, and a bayonet 6122 is fixed to the inner side wall of each side plate 612.

[0078] The adjustable baffle assembly 62 includes a limiting rod 621 and a baffle 622. The limiting rod 621 can move vertically along the guide groove 6121 and its vertical displacement is limited by the bayonet 6122. The baffle 622 is fixed to the limiting rod 621.

[0079] Vibration mechanism 63, the vibration mechanism 63 is located outside the side plate 612;

[0080] like Figure 12 As shown, when the limiting rod 621 is located at the bottom of the guide groove 6121, the baffle 622 is perpendicular to the mounting plate 611. This state can effectively prevent small tobacco fragments from falling into the conveyor belt. In order to avoid collision with the original equipment during installation, the baffle 622 can achieve stability in this state through the support of its own structure. At the same time, if necessary, stability in this state can be achieved through external connecting parts. Figure 11As shown in FIG14 , when the limiting rod 621 is located at the top of the guide groove 6121 , it can be inserted into the bayonet piece 6122 and detachably connected to the vibration mechanism 63 ; the vibration mechanism 63 drives the limiting rod 621 to swing periodically around the bayonet piece 6122 , thereby realizing the synchronous swing of the baffle 622 .

[0081] In order to further optimize the above technical solution, a fixed plate 613 is fixed to the outer wall of the side panel 612; the vibration mechanism 63 includes a driving part 631, a motion conversion part 632 and an elastic member 633, the driving part 631 is installed on the outer side of the side panel 612, the bottom end of the motion conversion part 632 is in contact with the action output end of the driving part 631, the top end of the motion conversion part 632 passes through the fixed plate 613, and is fastened to the limiting rod 621 by a fastener, the elastic member 633 is sleeved on the outer side of the motion conversion part 632, and its two ends are tightly pressed between the limiting rod 621 and the fixed plate 613.

[0082] In order to further optimize the above technical solution, the driving part 631 includes a motor 6311 and an eccentric wheel 6312 . The motor 6311 is installed on the outside of the side plate 612 , and the eccentric wheel 6312 is fixedly connected to the power output shaft of the motor 6311 .

[0083] In order to further optimize the above technical solution, the motion conversion part 632 includes a transmission plate 6321 and a transmission rod 6322. The lower surface of the transmission plate 6321 contacts the eccentric wheel 6312, and the bottom end of the transmission rod 6322 is vertically fixed on the upper surface of the transmission plate 6321, and its top end passes through the fixed plate 613 and is fixed to the limiting rod 621.

[0084] In order to further optimize the above technical solution, the limiting rod 621 is a U-shaped rod body with bent ends, and the top of the transmission rod 6322 is fixed to the bent portion 6211 of the limiting rod 621; the elastic member 633 is sleeved on the outside of the transmission rod 6322 and pressed tightly between the bent portion 6211 and the fixed plate 613.

[0085] In order to further optimize the above technical solution, a control unit is also included, and the control unit is electrically connected to the control end of the motor 6311.

[0086] In order to further optimize the above technical solution, the limiting rod 621 and the baffle 622 are fixedly connected via a support rod 623 , and an angle is formed between the support rod 623 and the baffle 622 .

[0087] like Figure 11 As shown, the support rod 623 includes a long support rod 6231 and multiple short support rods 6232. The long support rod 6231 is fixed to one side of the baffle 622 close to the limiting rod 621, and the multiple short support rods 6232 are fixed between the long support rod 6231 and the limiting rod 621.

[0088] In order to further optimize the above technical solution, one end of the baffle 622 close to the mounting plate 611 is a concave arc structure.

[0089] In order to further optimize the above technical solution, the bayonet of the bayonet piece 6122 is arranged toward the mounting plate, and its two ends are arc-shaped structures extending toward the central axial direction of the bayonet piece 6122.

[0090] In order to further optimize the above technical solution, the elastic member 633 is a return spring.

[0091] It can be seen from this that the adjustable tobacco gathering device 6 can realize two states of the baffle 622 through the guide groove 6121 and the bayonet piece 6122 design of the bottom box 61, and adjust the corresponding working state according to actual needs; when the limit rod 621 is located at the bottom of the guide groove 6121, the baffle 622 is perpendicular to the bottom plate 611, which can effectively prevent small tobacco fragments from falling into the Z-shaped conveyor belt. When the limit rod 621 is located at the top of the guide groove 6121 and is engaged with the bayonet piece 6122, the limit rod 621 is connected to the vibration mechanism 63, and under the drive of the vibration mechanism 63, the tobacco attached to the baffle 622 can be shaken off to prevent material accumulation, and thus can adapt to different tobacco accumulation conditions; the overall device adopts a modular design, which is easy to install, maintain and replace, saves space, and at the same time, can adapt to storage bins 7 and conveyor belts of different specifications, thereby improving the versatility and flexibility of the device.

[0092] In order to further optimize the above technical solution, Figure 15-17 As shown, the front and rear baffle assemblies 10 are also included, and the front and rear baffle assemblies 10 include:

[0093] The L-shaped plates 101 are symmetrically mounted on the upper surface of the bottom plate 611 in pairs. The L-shaped plates 101 are provided with J-shaped grooves 1011 (such as Figure 16 shown);
