Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a material transfer device. Background Technology

[0002] Belt conveyors are commonly used equipment in tobacco production and processing. They are typically used to transport materials such as tobacco leaves, shredded tobacco, tobacco leaves, and tobacco shreds. A moisture meter is usually installed below the material drop end of the belt conveyor to measure the moisture content of the material falling from the conveyor. For the moisture meter to work accurately, the material delivered to the measurement location must be continuous, uniform, and centered.

[0003] Existing belt conveyors often experience material deviation or clumping during operation, causing the material conveyed to the moisture meter measurement position to deviate to one side or become discontinuous and uneven. This results in inaccurate moisture meter readings and unqualified or uneven moisture content of the material.

[0004] Existing belt conveyors have a guiding mechanism at the discharge end to constrain the range of material falling. However, the existing guiding mechanism cannot automatically adjust the material flow rate according to the material position, and the material delivered to the moisture meter measurement position is still discontinuous and uneven. Utility Model Content

[0005] The purpose of this invention is to provide a material transfer device that can automatically adjust the flow rate of the material so that the material delivered to the moisture meter measurement position remains centered, uniform and continuous.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A material transfer device is provided, comprising:

[0008] The support member includes two support plates spaced apart along a first direction;

[0009] Two baffles are disposed on opposite sides of the two support plates, forming a material channel between the two baffles;

[0010] Two first compression mechanisms are provided, each corresponding to and connected to the baffle and the support plate. The baffle is connected to the first compression mechanism. When the baffle is squeezed, the two baffles can squeeze the first compression mechanism in a direction away from each other, and the first compression mechanism is compressed so that the two baffles move in a direction away from each other.

[0011] Optionally, the baffle includes a first adjusting part and a second adjusting part, the first adjusting part extends vertically, the second adjusting part is connected to the first adjusting part, and the bottom end of the second adjusting part extends toward each other, and the first compression mechanism is connected to the first adjusting part.

[0012] Optionally, the first compression mechanism includes a first elastic element and a first support rod. The first support rod is connected to the support plate and extends along the first direction. The first adjustment part is slidably connected to the first support rod. The first end of the first elastic element abuts against the support plate, and the second end of the first elastic element abuts against the first adjustment part.

[0013] Optionally, the first compression mechanism further includes a first fixing member, which is connected to the first support rod and abuts against the side of the first adjustment part opposite to the first elastic member.

[0014] Optionally, the first fastener is positionally adjustable to the first support rod.

[0015] Optionally, the second adjustment part can rotate relative to the vertical direction.

[0016] Optionally, the material transfer device further includes two second compression mechanisms, each corresponding to the baffle and the support plate, and the second compression mechanism is connected to the second adjustment part and the support plate.

[0017] Optionally, the second compression mechanism includes a second elastic element, a second support rod, and a second fixing element. The second support rod is fixedly connected to the second adjusting part and is inclined relative to the vertical direction. The support plate is provided with a through hole, through which the second support rod passes and extends out of the through hole. The second fixing element is connected to the second support rod and abuts against the side of the support plate opposite to the second elastic element. The first end of the second elastic element abuts against the support element, and the second end of the second elastic element abuts against the second adjusting part.

[0018] Optionally, the through hole is an oblong hole extending in the vertical direction.

[0019] Optionally, the second compression mechanism further includes a pad block, which has a second oblong hole extending in a vertical direction. The second support rod passes through the second oblong hole and the through hole in sequence. The pad block is located between the second elastic member and the support plate and abuts against the second elastic member and the support plate.

[0020] The beneficial effects of this utility model are:

[0021] This utility model provides a material transfer device, which includes a support member, two baffles, and two first compression mechanisms. A material channel is formed between the two baffles, through which the material conveyed by the conveyor belt can fall. The baffles limit the range of material falling, ensuring that the material falls to a designated position, thus acting as a guide. Even if the material on the conveyor belt deviates from its designated path, the baffles still prevent it from falling to the designated position, thus avoiding the material's inability to be detected by a moisture meter due to deviation on the conveyor belt.

[0022] The first compression mechanism corresponds one-to-one with the baffle and the support plate and is connected to the support plate to fix the first compression mechanism. The baffle is connected to the first compression mechanism. When the two baffles are squeezed, they can squeeze the first compression mechanism in a direction away from each other. The first compression mechanism is compressed, causing the two baffles to move away from each other, thereby increasing the material channel formed between the two baffles, thus increasing the material flow and preventing material blockage. When a small amount of material passes through the material channel, the material falls directly to the bottom. When a large amount of material passes through the material channel, the material squeezes the baffle, causing the baffle to squeeze the first compression mechanism. The first compression mechanism is compressed, causing the baffle to move, thereby increasing the material channel. The magnitude of the material squeezing force on the baffle is determined by the material flow in the material channel. The larger the material flow, the greater the material squeezing force on the baffle, the greater the compression of the first compression mechanism, and the greater the moving distance of the baffle, thus making the material channel larger and increasing the material flow. At the same time, the falling material layer will also become thinner, avoiding an excessively thick material layer. Furthermore, if the material deviates to one side, it concentrates on that side, resulting in greater pressure on the corresponding baffle. This causes the baffle on that side to move a greater distance, thus thinning the material layer and preventing uneven thickness. Therefore, the baffle's movement distance can be automatically adjusted based on the material flow rate and deviation. In addition, the baffle's buffering effect makes discontinuous material flow more continuous, further improving the accuracy of measurement results. Simultaneously, this material transfer device is extremely low-cost, simple in structure, easy to mass-produce, and highly practical. Attached Figure Description

[0035] 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.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] 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. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. 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.

[0039] like Figures 1-4 As shown, this embodiment provides a material transfer device, which includes a support member 1, two baffles 2, and two first compression mechanisms 3. The support member 1 includes two support plates 11 spaced apart along a first direction, and the two baffles 2 are disposed on opposite sides of the two support plates 11, forming a material channel between the two baffles 2. The material drop end of the conveyor belt 100 is disposed on one side of the baffle 2 along a second direction. The material conveyed by the conveyor belt 100 can fall below through the material channel. The baffles 2 can limit the range of material falling, allowing the material to fall to a designated position, thus serving as a guide. When the material conveyed on the conveyor belt 100 deviates from its designated position, the baffles 2 can still prevent the material from deviating from its designated position and thus preventing the material from being undetectable by a moisture meter.

[0040] The first compression mechanism 3 corresponds one-to-one with the baffle 2 and the support plate 11 and is connected to the support plate 11 to fix the first compression mechanism 3. The baffle 2 is connected to the first compression mechanism 3. When the baffle 2 is squeezed, the two baffles 2 can squeeze the first compression mechanism 3 in a direction away from each other. The first compression mechanism 3 is compressed, causing the two baffles 2 to move in a direction away from each other, thereby increasing the material channel formed between the two baffles 2, thereby increasing the material flow and avoiding material blockage. When a small amount of material passes through the material channel, the material falls directly to the bottom. When a large amount of material passes through the material channel, the material will squeeze the baffle 2, thereby causing the baffle 2 to squeeze the first compression mechanism 3. The first compression mechanism 3 is compressed, which drives the baffle 2 to move, thereby increasing the material channel. The magnitude of the squeezing force of the material on the baffle 2 is determined according to the material flow in the material channel. The larger the material flow, the greater the squeezing force of the material on the baffle 2, the greater the compression of the first compression mechanism 3, and the greater the moving distance of the baffle 2, thereby making the material channel larger and increasing the material flow. At the same time, the falling material layer will also become thinner, avoiding an excessively thick material layer. Furthermore, if the material deviates to one side, it concentrates on that side, resulting in greater pressure on the corresponding baffle 2. This causes the baffle 2 to move a greater distance on that side, thus thinning the material layer and preventing uneven thickness. Therefore, the distance the baffle 2 moves can be automatically adjusted based on the material flow rate and deviation. In addition, due to the buffering effect of the baffle 2, discontinuous material flow becomes more continuous, further improving the accuracy of measurement results. Simultaneously, this material transfer device has extremely low cost, simple structure, is easy to mass-produce, and is highly practical.

[0041] Specifically, the first direction is the X direction, which is the width direction of the conveyor belt 100. The second direction is the Y direction, which is the length direction of the conveyor belt 100, i.e., the conveying direction of the conveyor belt 100. The support member 1 also includes a first connecting plate 12 and a second connecting plate 13. The first connecting plate 12 and the second connecting plate 13 are respectively connected to the two support plates 11 at their two ends along the first direction. The first connecting plate 12 is connected to the upper end of the support plate 11, and the second connecting plate 13 is connected to the end of the support plate 11 away from the conveyor belt 100 along the second direction. The two support plates 11 are fixed by the first connecting plate 12 and the second connecting plate 13. At the same time, since the material is tobacco leaves, tobacco shreds, stems, etc., the material is relatively light. The first connecting plate 12 and the second connecting plate 13 act as a barrier to prevent dust pollution of the production environment during the material conveying process.

[0042] Optionally, such as Figure 2 and Figure 5As shown, the baffle 2 includes a first adjusting part 21 and a second adjusting part 22. The first adjusting part 21 extends vertically, and the second adjusting part 22 is connected to the first adjusting part 21. The bottom end of the second adjusting part 22 extends in a direction closer to each other, so that more material falls after being guided by the second adjusting part 22, further improving the uniformity of the material. The first compression mechanism 3 is connected to the first adjusting part 21 to drive the baffle 2 to move along the first direction.

[0043] Specifically, both the first adjusting part 21 and the second adjusting part 22 are square plates. The second adjusting part 22 is connected to the bottom end of the first adjusting part 21, and the included angle between the second adjusting part 22 and the first adjusting part 21 is an obtuse angle. The second adjusting part 22 and the first adjusting part 21 are integrally formed. In other embodiments, the shape of the baffle 2 can be set according to factors such as the flow rate and density of the material.

[0044] Optionally, such as Figures 1-3 As shown, the first compression mechanism 3 includes a first elastic element 31 and a first support rod 32. The first support rod 32 is connected to the support plate 11 and extends along a first direction. The first adjusting part 21 is slidably connected to the first support rod 32. The first end of the first elastic element 31 abuts against the support plate 11, and the second end of the first elastic element 31 abuts against the first adjusting part 21. When material squeezes the baffle 2, the first adjusting part 21 squeezes the first elastic element 31, compressing the first elastic element 31. This causes the first adjusting part 21 to move closer to the support plate 11, increasing the material passage.

[0045] Specifically, the first support rod 32 is a screw. The support plate 11 has a mounting hole 112 extending in a first direction. The first support rod 32 passes through the mounting hole 112 and is threaded with two nuts 34. The two nuts 34 abut against opposite sides of the support plate 11 to fix the first support rod 32 to the support plate 11. The first compression mechanism 3 also includes a first washer 35 and a second washer 36. Both the first washer 35 and the second washer 36 are annular structures, sleeved on the first support rod 32. The first washer 35 abuts against the nut 34 near the side of the baffle 2, facing away from the support plate 11. The first elastic element 31 is a spring. The first elastic element 31 is sleeved on the first support rod 32. The first end of the first elastic element 31 abuts against the side of the first washer 35 facing away from the nut 34, and the second end of the first elastic element 31 abuts against the second washer 36. The first adjusting part 21 is provided with a connecting hole. The first adjusting part 21 is sleeved on the first support rod 32 and abuts against the side of the second gasket 36 facing away from the first elastic member 31. In other embodiments, the first elastic member 31 may also be a sleeve made of elastic material.

[0046] In another embodiment, the first compression mechanism 3 includes a cylinder, which is fixedly connected to one side of the two support plates 11. The piston of the cylinder is capable of extending and retracting in a first direction, and the first adjusting part 21 is connected to the piston of the cylinder, thereby driving the baffle 2 to move in the first direction through the extension and retraction of the piston.

[0047] Furthermore, the first compression mechanism 3 also includes a first fixing member 33, which is connected to the first support rod 32 and abuts against the side of the first adjustment part 21 facing away from the first elastic member 31. The first fixing member 33 can limit the position of the baffle 2 and prevent the baffle 2 from sliding off the first support rod 32.

[0048] Furthermore, the first fixing member 33 is adjustablely connected to the first support rod 32. By adjusting the position of the first fixing member 33, the compression amount of the first elastic member 31 can be adjusted, thereby adjusting the initial position of the baffle 2. This allows for adjustment of the initial position of the baffle 2 based on the material flow rate and the material's position on the conveyor belt 100, ensuring that more material falls below the baffle 2 and improving material uniformity. Simultaneously, the compression force of the first elastic member 31 in its initial state can also be adjusted.

[0049] Specifically, the first fixing member 33 is a nut, which is convenient for adjustment and can achieve stepless adjustment. Two first fixing members 33 are provided, and the two first fixing members 33 are sequentially threadedly connected to the first support rod 32 and located on the same side of the support plate 11. By providing two first fixing members 33, the connection strength between the first fixing member 33 and the first support rod 32 is improved, making the first fixing member 33 less likely to fall off. In other embodiments, the first fixing member 33 can also be a screw, with multiple threaded holes spaced apart along a first direction on the first support rod 32, and the screw threadedly connected to one of the threaded holes.

[0050] Optionally, the second adjusting part 22 can rotate relative to the vertical direction. When the material flow rate is large, the material squeezes the second adjusting part 22, causing the bottom end of the second adjusting part 22 to rotate in a direction away from each other, further increasing the material channel.

[0051] Specifically, the baffle 2 can be an elastic baffle. When the material squeezes the second adjusting part 22, the second adjusting part 22 can deform, thereby rotating the second adjusting part 22 and increasing the material channel. In other embodiments, the second adjusting part 22 can also be rotatably connected to the first adjusting part 21 by a torsion spring. When the material squeezes the second adjusting part 22, the second adjusting part 22 can rotate relative to the first adjusting part 21. When the material does not squeeze the second adjusting part 22, the torsion spring can also cause the second adjusting part 22 to spring back.

[0052] Optionally, the material transfer device further includes two second compression mechanisms 4, which correspond one-to-one with the baffle 2 and the support plate 11. The second compression mechanism 4 is connected to the second adjustment part 22 and the support plate 11. The second compression mechanism 4 can support the second adjustment part 22 and limit the rotation range of the second adjustment part 22, thereby improving the stability of the second adjustment part 22.

[0053] Furthermore, the second compression mechanism 4 includes a second elastic element 41, a second support rod 42, and a second fixing element 43. The second support rod 42 is fixedly connected to the second adjusting part 22 and is inclined relative to the vertical direction. The second support rod 42 passes through and extends out of the through hole 111. The second fixing element 43 is connected to the second support rod 42 and abuts against the side of the support plate 11 facing away from the second elastic element 41. The first end of the second elastic element 41 abuts against the support member 1, and the second end of the second elastic element 41 abuts against the second adjusting part 22. The through hole 111 and the second fixing element 43 can limit the movement range of the second support rod 42, thereby limiting the rotation range of the second adjusting part 22 and preventing excessive extrusion pressure of the material on the baffle 2, which could damage the baffle 2.

[0054] Specifically, the second support rod 42 is vertically connected to the side of the second adjusting part 22 facing the support plate 11 and is welded to the second adjusting part 22, giving the second support rod 42 and the second adjusting part 22 a certain connection strength. The end of the second support rod 42 away from the second adjusting part 22 is provided with an external thread. The second fixing member 43 is a nut. Two second fixing members 43 are provided, and the two second fixing members 43 are sequentially threaded to the second support rod 42 and located on the same side of the support plate 11. A third washer 45 is provided between the second fixing member 43 and the support plate 11 to increase the contact area between the second fixing member 43 and the support plate 11. In other embodiments, the second fixing member 43 can also be a screw, with multiple threaded holes spaced apart along the axial direction of the second support rod 42, and the screw is threaded to one of the threaded holes. The second elastic member 41 is a spring, and the second elastic member 41 is sleeved on the second support rod 42.

[0055] Optionally, the through hole 111 is an oblong hole extending in the vertical direction, which can restrict the movement of the second support rod 42 in the second direction, thereby restricting the movement of the second adjustment part 22 in the second direction, preventing the second adjustment part 22 from shaking, and improving the stability of the baffle 2.

[0056] Optionally, such as Figure 2 , Figure 3 and Figure 6As shown, the second compression mechanism 4 also includes a pad 44, which has a second oblong hole 441 extending vertically. The second support rod 42 passes through the second oblong hole 441 and the through hole 111 in sequence. The pad 44 is located between the second elastic member 41 and the support plate 11, and abuts against both the second elastic member 41 and the support plate 11. The pad 44 increases the contact area between the second elastic member 41 and the support plate 11, dispersing the pressure of the second elastic member 41 on the support plate 11. Because the second support rod 42 is inclined, the second oblong hole 441 allows the second support rod 42 to move freely, preventing the pad 44 from restricting its movement.

[0057] 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.
