Technical Field

[0001] This invention relates to the field of tobacco leaf grading technology, and in particular to an automated dispersing device suitable for tobacco leaf piles. Background Technology

[0002] Tobacco leaves are often packaged in sacks during storage and transportation. The accumulated tobacco leaves, under the influence of gravity and temperature, release sticky substances such as tobacco oil, causing them to clump together. Currently, tobacco leaf separation mainly relies on manual labor, with workers peeling off the stuck leaves one by one. Due to the low efficiency and high labor requirements of manual labor, re-drying enterprises often face problems such as difficulty in recruiting workers and high costs.

[0003] To improve the automation level of tobacco leaf sorting and reduce labor costs, it is urgent to develop a device to solve the existing problems. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide an automated dispersing device suitable for tobacco leaf piles, which can realize the automated dispersing of tobacco leaf piles, help tobacco companies reduce the labor intensity of workers separating tobacco leaves, and improve the efficiency of tobacco leaf separating operations.

[0005] To address the aforementioned technical problems, the present invention provides an automated dispersing device suitable for tobacco leaf piles, comprising:

[0006] frame;

[0007] The lifting platform has its bottom set on the frame and its top used to place the pile of tobacco leaves to be dispersed.

[0008] Anti-tipping device, which includes a fencing structure located around the perimeter of the tobacco pile;

[0009] The tobacco leaf conveyor line has a loading end at one end along its own conveying direction. The loading end is located on one side of the lifting platform. The tobacco leaf conveyor line is used to transport the separated tobacco leaves to the downstream work station.

[0010] The tobacco leaf separating mechanism includes a motion guide component, a drive unit, and a tobacco leaf separating component. The motion guide component is mounted on the frame and located above the lifting platform. The drive unit is mounted on the motion guide component. Part of the structure of the tobacco leaf separating component is connected to the drive unit. Under the drive of the drive unit, the position or shape of the tobacco leaf separating component changes to feed the tobacco leaves from the top of the tobacco pile to the loading end of the tobacco leaf conveyor line.

[0011] Preferably, the motion guide assembly includes multiple parallel slide rails, and the number of actuators is multiple, with each actuator corresponding to one of the slide rails, and each actuator is linearly slidably disposed on the corresponding slide rail.

[0012] Preferably, the tobacco leaf separating component is one of a separating cloth, a separating board, and a separating rope.

[0013] Preferably, the tobacco leaf separating component is a separating cloth, with multiple actuators connected to the top corner and / or edge of the separating cloth. Under the action of the actuators, the separating cloth switches between a spread-out state and a folded state.

[0014] Preferably, all the actuators are divided into multiple groups, each group including two actuators at the same height, and the two actuators belonging to the same group are symmetrically connected on opposite sides of the dispensing fabric perpendicular to its own sliding direction.

[0015] Preferably, the enclosure structure includes a side barrier adjuster and a baffle. The side barrier adjuster is mounted on the frame, and the baffle is mounted on the side barrier adjuster and engages with the pile of tobacco leaves to be dispersed.

[0016] Preferably, the drive is a linear motor module.

[0017] Preferably, the tobacco leaf conveying line is a conveyor belt.

[0018] Preferably, the lifting platform includes a lifting regulator and a support plate for placing the tobacco leaf pile to be dispersed. The lifting regulator is located on the frame, and the support plate is located on the lifting regulator.

[0019] Preferably, the frame includes a base for mounting the lifting platform.

[0020] As described above, the automated dispersing device for tobacco piles of the present invention has the following beneficial effects: In the automated dispersing device of this application, the top of the lifting platform is used to place the tobacco pile to be dispersed, and the bottom of the lifting platform is located on the frame, thus allowing adjustment of the height of the tobacco pile to be dispersed. The anti-tipping device includes a baffle structure located around the outer periphery of the tobacco pile, thus preventing the tobacco pile from tipping over during the separation process; one end of the tobacco conveyor line along its own conveying direction is the loading end, located on one side of the lifting platform, thus enabling the separated tobacco leaves to be conveyed to the downstream workstation. The main innovation of this application lies in the tobacco leaf separation mechanism, which includes a motion guide assembly, a drive, and a tobacco leaf separation component. The motion guide assembly is located on the frame and above the lifting platform, the drive is movably mounted on the motion guide assembly, and a portion of the structure of the tobacco leaf separation component is connected to the drive. Under the driving action of the drive, the position or shape of the tobacco leaf separation component changes to feed the tobacco leaves from the top of the tobacco pile to the loading end of the tobacco conveyor line. Specifically, driven by the aforementioned actuator, the tobacco leaf separating component moves along the extension direction of the motion guide assembly. In conjunction with the surrounding enclosure structure of the tobacco pile, a small amount of tobacco leaves from the upper part of the pile placed on the lifting platform fall onto the separating component or are pushed away from the pile, thus gradually separating the tobacco pile. The shape or posture of the separating component can be changed by adjusting the clamping position and speed of the actuator, thereby altering the angle at which it extends into the tobacco pile. This adjusts the friction and thrust between the separating component and the pile. Furthermore, the speed can be adjusted to fold or flip the separating component, facilitating the separating and dropping of the tobacco leaves. Therefore, this invention, applicable to automated tobacco pile dispersion devices, enables automated dispersion of tobacco piles, helping tobacco companies reduce the labor intensity of workers separating tobacco leaves and improve operational efficiency.

[0024] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0025] It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings of this specification are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of the invention. Therefore, they have no substantial technical significance.

[0026] To address the problems of high labor intensity and low efficiency in manually separating sticky tobacco leaves, this application proposes a corresponding device to solve the existing problems, achieving automated dispersion of accumulated tobacco leaves. (Refer to...) Figure 1 , Figure 2 As shown, the present invention provides an automated dispersing device suitable for tobacco piles, comprising:

[0027] frame;

[0028] Lifting platform 6, the bottom of lifting platform 6 is set on the frame, and the top of lifting platform 6 is used to place the pile of tobacco leaves 8 to be dispersed;

[0029] Anti-tipping device, which includes a fencing structure located around the outer perimeter of the tobacco pile 8;

[0030] The tobacco leaf conveyor line has a loading end at one end along its own conveying direction. The loading end is located on one side of the lifting platform 6. The tobacco leaf conveyor line is used to transport the separated tobacco leaves to the downstream work station.

[0031] The tobacco leaf separating mechanism includes a motion guide assembly, a drive unit, and a tobacco leaf separating component. The motion guide assembly is located on the frame and above the lifting platform 6. The drive unit is mounted on the motion guide assembly. Part of the structure of the tobacco leaf separating component is connected to the drive unit. Under the drive of the drive unit, the position or shape of the tobacco leaf separating component changes to feed the tobacco leaves on the top of the tobacco leaf pile 8 to the loading end of the tobacco leaf conveyor line.

[0032] In the automated dispersing device of this application, the top of the lifting platform 6 is used to place the tobacco leaf pile 8 to be dispersed, and the bottom of the lifting platform 6 is located on the frame, so that the height of the tobacco leaf pile 8 to be dispersed can be adjusted. The anti-tipping device includes a baffle structure located around the outer periphery of the tobacco leaf pile 8, which prevents the tobacco leaf pile 8 from tipping over during the separation process; one end of the tobacco leaf conveyor line along its own conveying direction is the loading end, which is located on one side of the lifting platform 6, so that the separated tobacco leaves can be transported to the downstream station. The main innovation of this application is the tobacco leaf separation mechanism, which includes a motion guide component, a drive, and a tobacco leaf separation component. The motion guide component is located on the frame and above the lifting platform 6. The drive is movably mounted on the motion guide component. Part of the structure of the tobacco leaf separation component is connected to the drive. Under the action of the drive, the position or shape of the tobacco leaf separation component changes to feed the tobacco leaves on the top of the tobacco leaf pile 8 to the loading end of the tobacco leaf conveyor line.

[0033] Specifically, driven by the aforementioned actuator, the tobacco leaf separating component moves along the extension direction of the motion guide assembly. In conjunction with the surrounding enclosure structure of the tobacco pile, a small amount of tobacco leaves from the upper part of the pile placed on the lifting platform fall onto the separating component or are pushed away from the pile, thus gradually separating the tobacco pile. The shape or posture of the separating component can be changed by adjusting the clamping position and speed of the actuator, thereby altering the angle at which the component extends into the tobacco pile. This allows for adjustment of the friction and thrust between the separating component and the pile. Furthermore, the speed can be adjusted to fold or flip the separating component, achieving the tobacco leaf separating and unloading process.

[0034] Therefore, the automated dispersing device for tobacco leaf piles of the present invention can realize the automated dispersing of tobacco leaf piles 8, helping tobacco companies reduce the labor intensity of workers separating tobacco leaves and improve the efficiency of tobacco leaf separation operations.

[0035] In order to simplify the structure of the motion guide component and cause changes in the position or shape of the tobacco leaf separating component from multiple angles, the motion guide component includes multiple parallel slide rails 2, and multiple actuators, with each actuator corresponding to each slide rail 2, and each actuator is linearly slidably mounted on the corresponding slide rail 2.

[0036] Depending on the incoming material conditions and process requirements, the above-mentioned tobacco leaf separating component can be one of the following: separating cloth 3, separating plate, and separating rope.

[0037] Because the fabric is relatively light, it can be taut, loose, or in various other forms. The aforementioned tobacco leaf separating component is a separating cloth 3. The top corner and / or edge of the separating cloth 3 are connected to multiple actuators. Under the action of the actuators, the separating cloth 3 switches between a stretched state and a folded state. This is more conducive to the separating operation of the top tobacco leaves of the tobacco pile 8.

[0038] To facilitate switching between the unfolded and folded states of the fabric 3, all the aforementioned actuators are divided into multiple groups. Each group includes two actuators at the same height, and the two actuators belonging to the same group are symmetrically connected to opposite sides of the fabric 3 perpendicular to its sliding direction. Specifically, the two actuators belonging to the first group are connected to the two corners of the fabric 3, and the two actuators belonging to the second group are connected to the other two corners of the fabric 3. In addition, the two actuators belonging to the third group are connected to the two edges of the fabric 3.

[0039] To adjust the placement area defined by the aforementioned enclosure structure, the enclosure structure includes a side barrier adjuster and baffles 7. The side barrier adjuster is mounted on the frame, and the baffles 7 are mounted on the side barrier adjuster and abut against the pile of tobacco leaves 8 to be dispersed. The side barrier adjuster can be a horizontal adjustment cylinder 5. The number of baffles 7 can be two or four.

[0040] To reduce the research and development and manufacturing costs of the device, the aforementioned drive is a linear motor module 1 based on existing technology, and its specific structure will not be described in detail.

[0041] To reduce the research and development and manufacturing costs of the equipment, the above-mentioned tobacco leaf conveying line is a conveyor belt 9.

[0042] To simplify the structure of the lifting platform 6, the lifting platform 6 includes a lifting regulator and a support plate for placing the tobacco leaf pile 8 to be dispersed. The lifting regulator is located on the frame, and the support plate is located on the lifting regulator. The lifting regulator can be a vertical adjustment cylinder.

[0043] In order to support the load of the lifting platform 6, the frame includes a base 4, which is used to mount the lifting platform 6.

[0044] like Figure 1 and Figure 2 As shown in the figure, as a specific embodiment of the above-mentioned automated dispersing device for tobacco piles, it mainly consists of a linear motor module, a slide rail, a dispersing cloth made of nylon, a base, a horizontal adjustment cylinder, a lifting platform, a baffle, and a conveyor belt.

[0045] The linear motor module 1 is arranged on the slide rail 2 and can reciprocate along the slide rail 2. The separating cloth 3 is fixed on the linear motor module 1. When the linear motor module 1 slides along the slide rail, it can drive the nylon cloth 3 to reciprocate. By adjusting the position of the separating cloth 3 held by the linear motor module 1 and the speed of the linear motor module 1, the contour and tension of the separating cloth 3 during sliding can be adjusted, allowing it to better penetrate into the tobacco pile 8. By adjusting different speeds of the linear motor module 1, the upper and lower surfaces of the separating cloth 3 can also be folded to achieve the material dropping function. The horizontal adjusting cylinder 5 is connected to the baffle 7. By extending and retracting the horizontal adjusting cylinder 5, tobacco piles 8 of different shapes and sizes can be more tightly fixed in the baffle 7 to prevent material from tipping over during tobacco leaf dispersion operations. The lifting platform 6 is fixed on the base 4, and the height of the upper tobacco pile 8 can be adjusted by the lifting platform 6. The conveyor belt 9 is located at the rear end of the slide rail 2 and is used to transport the tobacco leaves separated by the separating cloth 3.

[0046] Specifically, in the automatic tobacco leaf dispersing device, the linear motor module 1 is arranged on the slide rail 2 and can reciprocate linearly along the slide rail 2. The separating cloth 3 is fixed on the linear motor module 1, and when the linear motor module 1 moves, it drives the separating cloth 3 to reciprocate. By adjusting the clamping position of the linear motor module 1 and the separating cloth 3, as well as the speed of the linear motor module 1, the contour and tension of the separating cloth 3 can be changed, allowing the separating cloth 3 to better penetrate into the interior of the tobacco pile 8. When the separating cloth 3 slides from left to right along the slide rail, the right end of the separating cloth 3 can be inserted into the interior of the tobacco pile 8 through the gaps in the tobacco stems or leaves on the left side of the tobacco pile 8. Due to the flexibility of the separating cloth 3, under tension, it can deform appropriately along the small gaps inside the tobacco pile, thereby separating the upper layer of tobacco leaves from the tobacco pile 8 and placing them on top of the separating cloth 3. When the separating cloth 3 slides to the rear end of the slide rail 2, by gradually adjusting the speed of the linear motor module 1—increasing the speed of the upper motor and decreasing the speed of the lower motor—the positions of the upper and lower surfaces of the separating cloth 3 can be reversed, causing the tobacco leaves on the upper part of the separating cloth 3 to fall onto the lower conveyor belt 9, thus achieving the function of discharging the tobacco leaves after dispersion. Afterwards, the linear motor module 1 drives the separating cloth 3 to quickly return to the left side of the tobacco pile 8. The lifting platform 6, located on the base 4, is appropriately raised so that a small amount of tobacco leaves on the upper part of the tobacco pile 8 are above the upper surface of the separating cloth 3, preparing for the further separation of the upper tobacco leaves. To prevent the tobacco pile 8 from tipping over during the separation operation, the tobacco pile 8 needs to be properly fixed using the horizontal adjusting cylinder 5 and the baffle 7, providing appropriate support for the separating cloth 3 to separate the upper tobacco leaves. The lifting platform 6 rises only a small height each time, so the weight of tobacco leaves that the separating cloth 3 needs to separate each time is relatively light. For tobacco leaves that are too tightly compacted, the separating cloth 3 cannot penetrate deep into the tobacco pile. Since the separating cloth 3 only needs to overcome the weight of a small amount of upper tobacco leaves and the adhesion between the tobacco leaves, it can also be used to push and peel them off. Finally, the linear motor module 1 drives the reciprocating motion of the separating cloth 3 to gradually disperse the tobacco pile 8 from top to bottom.

[0047] In practical applications, the moisture content, adhesion, and compaction degree of tobacco leaf piles will vary. During implementation, the separating cloth 3 can be replaced with other materials or shapes such as steel plates and steel wire ropes, depending on the material conditions and process requirements. For example, for tobacco leaves with high moisture content and light compaction, steel plates can be used instead of the separating cloth; for equipment processes that only require breaking adhesion, with subsequent dispersion handled by other equipment, steel wire ropes can be used instead of the separating cloth.

[0048] In summary, this invention enables the automated dispersal of tobacco leaf piles 8, helping tobacco companies reduce the labor intensity of workers separating tobacco leaves and improve the efficiency of tobacco leaf separation operations. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and has high industrial application value.

[0049] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
