Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibratory conveying equipment technology, and in particular to trough structure and material conveying device. Background Technology
[0002] In the tobacco processing industry, tobacco conveying is a crucial step. Traditional tobacco conveying devices mainly consist of a support frame, a vibrating trough movably connected to the support frame, and multiple swing arms rotatably connected to the support frame. The upper ends of the swing arms are hinged to the vibrating trough, and the lower ends are hinged to counterweights. Driven by a power source, the counterweights drive the swing arms to move together, thereby causing the vibrating trough to swing back and forth, throwing the finished tobacco shreds in the vibrating trough forward, thus completing the conveying operation.
[0003] However, in the cigarette manufacturing process, the tobacco shreds need to undergo a heating and humidification process. When the tobacco shreds processed by the heating and humidification process come into contact with the right-angle part of the trough, they are prone to sticking and accumulating, and over time they will become overly wet tobacco shreds. Overly wet tobacco shreds not only affect the quality and uniformity of the tobacco shreds, but may also contaminate normal tobacco shreds, resulting in resource waste and increased production costs. Utility Model Content
[0004] The purpose of this invention is to provide a trough structure and material conveying device that can improve the quality and uniformity of tobacco, reduce material waste, and lower production costs.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] The tank structure includes:
[0007] Base plate;
[0008] Two side plates are spaced apart along a first horizontal direction, and each side plate is smoothly connected to the bottom plate through a first arc-shaped surface.
[0009] A connecting plate is connected to two side plates and to a bottom plate. The connecting plate, the bottom plate, and the two side plates enclose a material receiving space. An inlet is formed above the material receiving space. An outlet is formed on the side of the bottom plate away from the connecting plate along the second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction.
[0010] Optionally, the base plate is provided with a reinforcing member extending in a second horizontal direction, the reinforcing member being located on one side of the base plate within the material receiving space.
[0011] Optionally, the reinforcing member is smoothly connected to the base plate on both sides in the first horizontal direction via a second arc-shaped surface.
[0012] Optionally, one end of the second arc-shaped surface is tangent to the reinforcing member, and the other end is tangent to the base plate.
[0013] Optionally, multiple reinforcing members are provided, and the multiple reinforcing members are distributed at intervals along the first horizontal direction.
[0014] Optionally, one end of the first arcuate surface is tangent to the corresponding side plate, and the other end is tangent to the bottom plate.
[0015] Optionally, the tank structure is a one-piece molded structure.
[0016] Material conveying device, including:
[0017] Tank structure;
[0018] The support assembly includes a frame and legs fixedly connected to the frame, the legs being used to support the frame, and a trough structure being movably connected to the frame.
[0019] The drive unit is capable of driving the tank structure to reciprocate along the second horizontal direction.
[0020] Optionally, the material conveying device further includes a counterweight block, which is movably connected to the frame. The trough structure and the counterweight block are located on both sides of the frame. The trough structure, the frame, and the counterweight block are provided with a swing arm on at least one side along the first horizontal direction. The upper part of the swing arm is rotatably connected to the side plate through a first rotating shaft, the middle part of the swing arm is rotatably connected to the frame through a second rotating shaft, and the lower part of the swing arm is rotatably connected to the counterweight block through a third rotating shaft.
[0021] The drive unit includes a drive motor and a rotating wheel. The drive motor is fixed to the frame. The output end of the drive motor is coaxial with and fixedly connected to the rotating wheel. A connecting rod is rotatably connected to the third rotating shaft. The connecting rod is eccentrically set with the rotating wheel.
[0022] Optionally, one of the trough structure and the frame is provided with a slider, and the other is provided with a sliding groove, with the slider and the sliding groove slidingly engaged.
[0023] The beneficial effects of this utility model are:
[0024] The trough structure and material conveying device provided by this utility model allow tobacco shreds to enter the material receiving space through the feed inlet. Each side plate is smoothly connected to the bottom plate through a first arc-shaped surface, improving the original line contact at the right angle to a surface contact. This increases the contact area between the tobacco shreds and the trough structure, resulting in uniform force distribution and allowing the tobacco shreds to slide elastically within the trough structure. When the tobacco shreds are conveyed within the trough structure, the frictional resistance between the side plates and the bottom plate is significantly reduced, effectively ensuring the potential energy for the tobacco shreds to move forward. This enables effective vibration conveying of the tobacco shreds, reducing the adhesion and retention of tobacco shreds within the trough structure. Specifically, it improves the situation where tobacco shreds adhere to the right angle and become overly wet, thereby improving the quality and uniformity of the tobacco shreds, reducing material waste, and lowering production costs.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0034] This utility model provides a trough structure 1 and a material conveying device including the trough structure 1, the material conveying device being used to convey materials within the trough structure 1. Exemplarily, the material conveying device is a tobacco conveying device; the following description uses a tobacco conveying device as an example.
[0035] like Figure 1-2 As shown, an embodiment of this utility model provides a tank structure 1, including a bottom plate 11, a connecting plate 13, and two side plates 12. The two side plates 12 are spaced apart along a first horizontal direction. Each side plate 12 is smoothly connected to the bottom plate 11 through a first arc-shaped surface 14. The connecting plate 13 is connected to the two side plates 12 and the bottom plate 11. The connecting plate 13, the bottom plate 11, and the two side plates 12 enclose a material receiving space. An inlet is formed above the material receiving space. An outlet is formed on the side of the bottom plate 11 away from the connecting plate 13 along a second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction.
[0036] The trough structure 1 is designed as a U-shaped structure. The tobacco enters the material receiving space through the feed inlet. Each side plate 12 is smoothly connected to the bottom plate 11 through the first arc surface 14, improving the original line contact at the right angle to a surface contact. This increases the contact area between the tobacco and the trough structure 1, resulting in a more uniform force distribution. This allows the tobacco to slide elastically within the trough structure 1. When the tobacco is conveyed within the trough structure 1, the frictional resistance between the side plate 12 and the bottom plate 11 is significantly reduced, effectively ensuring the potential energy for the tobacco to move forward. This enables effective vibration conveying of the tobacco, reducing the adhesion and retention of the tobacco within the trough structure 1. In other words, the situation where the tobacco adheres to the right angle and becomes overly wet is basically eliminated. This improves the quality and uniformity of the tobacco, reduces material waste, and lowers production costs.
[0037] Furthermore, one end of the first arc-shaped surface 14 is tangent to the corresponding side plate 12, and the other end is tangent to the bottom plate 11. This arrangement makes the change in the direction of tobacco movement smoother, enhances guidance, and improves conveying efficiency.
[0038] Furthermore, the base plate 11 is provided with a reinforcing member 15 extending along the second horizontal direction, the reinforcing member 15 being located on one side of the base plate 11 within the material receiving space.
[0039] By providing reinforcing members 15 on the base plate 11, the structural strength of the base plate 11 can be improved, making the base plate 11 less prone to deformation during the vibration conveying of tobacco, thereby improving the stability of the base plate 11 during operation and extending the service life of the base plate 11.
[0040] For example, the reinforcing member 15 is a raised structure formed by the arching of the base plate 11. This arrangement can reduce the material cost of the base plate 11. In other embodiments, the reinforcing member 15 may also be a reinforcing rib integrally formed with the base plate 11.
[0041] Furthermore, the reinforcing member 15 is smoothly connected to the base plate 11 on both sides of the first horizontal direction through the second arc-shaped surface 16.
[0042] Similarly, the reinforcing member 15 is smoothly connected to the bottom plate 11 on both sides of the first horizontal direction through the second arc surface 16, which increases the contact area between the tobacco and the bottom plate 11, and the force distribution is uniform. This allows the tobacco fibers to slide elastically within the trough structure 1, and the frictional resistance between the tobacco and the bottom plate 11 is greatly reduced. This effectively ensures the potential energy for the tobacco to move forward, enabling effective vibration conveying of the tobacco, reducing the adhesion and retention of the tobacco within the trough structure 1, improving the quality and uniformity of the tobacco, reducing material waste, and lowering production costs.
[0043] Furthermore, one end of the second arc-shaped surface 16 is tangent to the reinforcing member 15, and the other end is tangent to the base plate 11. This arrangement makes the change in the direction of tobacco movement smoother, enhances guidance, and improves conveying efficiency.
[0044] Furthermore, multiple reinforcing members 15 are provided, and the multiple reinforcing members 15 are distributed at intervals along the first horizontal direction.
[0045] Specifically, such as Figure 1 As shown, two reinforcing members 15 are provided, which further enhances the structural strength of the base plate 11, greatly improves the working stability of the base plate 11, and extends its service life. Understandably, the number of reinforcing members 15 can be set according to the actual dimensions of the tank structure 1 and specific requirements.
[0046] like Figure 2 As shown, an embodiment of this utility model provides a material conveying device, including a support assembly 2, a drive unit, and the aforementioned trough structure 1. The support assembly 2 includes a frame 21 and legs 22 fixedly connected to the frame 21, which support the frame 21. The trough structure 1 is movably connected to the frame 21, and the drive unit can drive the trough structure 1 to reciprocate along a second horizontal direction. Specifically, the second horizontal direction is the conveying direction of the tobacco.
[0047] The drive unit drives the trough structure 1 to reciprocate along the second horizontal direction, thereby driving the trough structure 1 to reciprocate. When the trough structure 1 moves forward, the tobacco shreds lag behind the movement of the trough structure 1 due to inertia. The tobacco shreds and the trough structure 1 slide relative to each other. Under the continuous drive of the drive unit, the tobacco shreds in the trough structure 1 can be thrown forward to complete the conveying work, so that the tobacco shreds can proceed to the next process.
[0048] For example, the material conveying device further includes a counterweight 3, which is movably connected to the frame 21. The trough structure 1 and the counterweight 3 are located on both sides of the frame 21. The trough structure 1, the frame 21, and the counterweight 3 are provided with a swing arm 4 on at least one side along the first horizontal direction. The upper part of the swing arm 4 is rotatably connected to the side plate 12 through a first rotating shaft, the middle part of the swing arm 4 is rotatably connected to the frame 21 through a second rotating shaft, and the lower part of the swing arm 4 is rotatably connected to the counterweight 3 through a third rotating shaft. The drive unit includes a drive motor and a wheel. The drive motor is fixed to the frame 21. The output end of the drive motor is coaxial with and fixedly connected to the wheel. The third rotating shaft is rotatably connected to a connecting rod, which is eccentrically set with respect to the wheel.
[0049] The drive motor drives the rotating wheel to rotate, which in turn drives the connecting rod to make an eccentric motion. The connecting rod drives the counterweight 3 to move together. Under the action of the swing arm 4, the counterweight 3 drives the trough structure 1 to swing back and forth, thereby throwing the tobacco in the trough structure 1 forward and completing the conveying work.
[0050] In other embodiments, the driving unit may also be a telescopic cylinder, with its output end fixedly connected to the connecting plate 13 of the tank structure 1. The telescopic cylinder can drive the tank structure 1 to reciprocate along the second horizontal direction. Optionally, the driving unit may be a hydraulic telescopic cylinder or a pneumatic telescopic cylinder.
[0051] Furthermore, multiple swing arms 4 are provided, and the multiple swing arms 4 are respectively provided on both sides of the frame 21 along the first horizontal direction and correspond one to one. The multiple swing arms 4 on each side are spaced apart along the second horizontal direction.
[0052] By setting multiple swing arms 4 on both sides of the frame 21, the force is evenly distributed, which can improve the stability of the trough structure 1 during reciprocating motion.
[0053] Furthermore, one of the trough structure 1 and the frame 21 is provided with a slider, and the other is provided with a sliding groove, with the slider and the sliding groove slidingly engaged.
[0054] By using a slider in conjunction with a chute, the trough structure 1 can be guided, thereby ensuring that the tobacco shreds do not deviate during the conveying process.
[0055] For example, the bottom plate 11 has a slider on the side facing away from the material receiving space, and the frame 21 has a sliding groove. In other embodiments, the bottom plate 11 has a roller on the side facing away from the material receiving space, and the frame 21 has a rolling groove, with the roller and the rolling groove engaging in rolling cooperation.
[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
