Description

Technical Field

[0001] This utility model relates to the field of tobacco technology, and in particular to a sealed quantitative collection device for recycling shredded tobacco. Background Technology

[0002] In the process of recovering tobacco scraps in cigarette making machines, the separated usable tobacco scraps often need to be temporarily collected and transported twice before being returned to the production chain. Currently, silos, hoppers, or simple collection boxes are commonly used as transitional devices, but these devices have the following problems:

[0003] 1. Traditional silos have insufficient sealing at the material inlet, making it difficult to form an effective isolation. During operation, air can easily form a convection channel along the inlet, causing the separated tobacco shreds to be rolled up again, carrying fine dust into the airflow, resulting in secondary dust. This not only affects the purity of the recovered material, but also increases the dust removal burden.

[0004] 2. Traditional silos are mostly in a "fully open / fully closed" discharge mode, which cannot release small batches and quantities of materials according to the production cycle. This can easily cause uneven material supply in the return chain and affect the stability of subsequent mixing processes.

[0005] Therefore, there is an urgent need to design a new sealed quantitative collection device, particularly for the recycling of shredded tobacco, to improve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a sealed quantitative collection device for the recycling of shredded tobacco, so as to solve the technical problems of insufficient sealing of the material inlet of traditional silos, resulting in secondary dust and material back-mixing, affecting the purity of the recycled material, increasing the dust removal burden, making it impossible to achieve small batch and quantitative material release, and easily causing uneven material supply in the return link.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] The sealed quantitative collection device for recycling shredded tobacco provided by this utility model includes:

[0009] The box body has a material inlet at the top and a positive pressure air inlet and a negative pressure suction inlet at the bottom, with the positive pressure air inlet and the negative pressure suction inlet respectively located on opposite sides of the bottom of the box body;

[0010] A movable plate, one side of which is rotatably mounted on the inner wall of the housing via a pivot, and the other side of which is a movable end, and a driving component connected to the pivot and driving the movable plate to rotate is provided on the outside of the housing;

[0011] The movable plate has at least a closed state and an open state. When the movable plate is in the closed state, the movable end of the movable plate abuts against the inner wall of the box, so that the internal space of the box is divided into an upper chamber and a lower chamber. When the movable plate is in the open state, the movable end of the movable plate tilts downward and rotates so that the upper chamber is connected to the lower chamber.

[0012] The movable plate, driven by a driving component, rotates to the closed state. The movable end of the plate abuts against the inner wall of the housing, dividing the interior of the housing into an upper chamber and a lower chamber. The material inlet at the top of the housing is connected to the material outlet of the preceding separation device to receive the tobacco fragments discharged from the separation device. After entering the housing through the material inlet, the tobacco fragments fall onto the movable plate, i.e., into the upper chamber. The movable plate forms a sealing barrier to the material inlet, blocking the airflow exchange between the upper and lower chambers. The upper airflow cannot directly enter the lower part of the housing, thus avoiding the problem of secondary dust and tobacco fragments being thrown upwards due to pressure difference.

[0013] Once the upper chamber is filled to the preset full capacity, the drive unit rotates the movable plate to the open position. The shredded tobacco in the upper chamber quickly falls into the lower chamber along the inclined surface of the movable plate and finally gathers at the drop point in the center of the bottom wall of the box. The drive unit moves the movable plate to seal and separate the inside of the box, realizing batch and quantitative control of the shredded tobacco, ensuring the uniformity of the feed in the return link, and reducing the possibility of material blockage.

[0014] When the movable plate is closed, the positive pressure air inlet and the negative pressure suction inlet are also closed, and the lower chamber remains stationary, thus ensuring that the shredded tobacco settles stably to the discharge point. When the movable plate is open, the positive pressure air inlet and the negative pressure suction inlet open simultaneously. The airflow from the positive pressure air inlet blows the shredded tobacco in the lower chamber from the discharge point and sucks it away through the negative pressure suction inlet, thereby realizing the pneumatic return of the shredded tobacco. Through the opening and closing of the positive pressure air inlet and the negative pressure suction inlet, stable pneumatic return is maintained. The overall structure is simple and compact, with good adaptability and scalability.

[0015] As a preferred embodiment of a sealed quantitative collection device for recovering shredded tobacco, the box is rectangular in shape, the height of the box is greater than the width of the box, and when the movable plate is in the open state, there is a gap between the movable end and the inner bottom wall of the box.

[0016] When the movable plate rotates to a horizontal or nearly horizontal position, the movable end of the movable plate remains pressed against the inner wall of the box to achieve a sealed fit between the movable plate and the box. When the movable plate rotates to an inclined position, the extension direction of the movable end of the movable plate points to the center of the inner bottom wall of the box, and the gap between the movable end and the inner bottom wall of the box allows the shredded tobacco to smoothly enter the lower chamber. Through the cooperation of the movable plate, the discharge point, and the chamber, the shredded tobacco is prevented from forming bridges and accumulating in the box, ensuring that the shredded tobacco can settle and be discharged smoothly.

[0017] As a preferred embodiment of a sealed quantitative collection device for recovering shredded tobacco, the movable plate and its opposite sides adjacent to the movable end are respectively tightly fitted to the two opposite inner sidewalls of the box.

[0018] The two opposite sides of the movable plate fit tightly against the two opposite inner side walls of the box, ensuring the sealing performance of the sealing plate.

[0019] As a preferred embodiment of a sealed quantitative collection device for recycling shredded tobacco, a mounting base is provided on the inner side wall of the housing, and a groove is provided at the bottom of the mounting base for the rotating shaft portion of the movable plate to be inserted.

[0020] The mounting base fits tightly against the inner wall of the enclosure, and the rotating shaft is embedded in the groove, which tightly covers the gap between the rotating shaft and the inner wall of the enclosure for rotational installation, so as to further ensure the sealing performance of the sealing plate.

[0021] As a preferred embodiment of a sealed quantitative collection device for recovering shredded tobacco, the top surface of the mounting base is configured as an inclined surface, which slopes from one side of the housing toward the center point of the housing.

[0022] The tobacco shreds that fall onto the mounting base will slide down the slope of the mounting base onto the movable plate, reducing the occurrence of tobacco shreds accumulating and getting stuck.

[0023] As a preferred embodiment of a sealed, quantitative collection device for recovering shredded tobacco, the driving component includes:

[0024] A rotating block, one end of which is connected to the rotating shaft;

[0025] A telescopic cylinder, the end of which is rotatably connected to the outer wall of the housing, and the telescopic end of which is rotatably connected to the other end of the rotating block.

[0026] One side of the movable plate is mechanically linked with the telescopic cylinder and the rotating block. The telescopic cylinder drives the rotating block to rotate, thereby rotating the movable plate. The telescopic cylinder drives the movable plate to open or close, achieving rapid opening and closing and reliable control during the collection and release of tobacco shreds.

[0027] As a preferred embodiment of a sealed quantitative collection device for recycling shredded tobacco, the top of the box is open, and a top cover is detachably connected to the open part of the box, with the material inlet located on the top cover.

[0028] The top opening of the enclosure can be opened by directly removing the top cover, making it convenient for operators to repair and maintain the internal structure of the enclosure, and also making it easy to clean impurities and dirt inside the enclosure.

[0029] As a preferred embodiment of a sealed quantitative collection device for recovering shredded tobacco, a pipe is detachably connected to the negative pressure inlet.

[0030] The shredded tobacco is transported to the downstream conveying link through a pipeline via a negative pressure suction port, realizing the pneumatic return of the shredded tobacco.

[0031] As a preferred embodiment of a sealed, quantitative collection device for recovering shredded tobacco, the pipeline is connected to a butterfly valve.

[0032] The butterfly valve, positive pressure port, and movable plate have a strict sequence of opening and closing. First, tobacco fragments are collected, then the airflow is returned, preventing the tobacco fragments from being disturbed by turbulence during release. The butterfly valve has few components, is small in size, and lightweight. When fully open, the thickness of the butterfly plate is the only resistance, resulting in a large flow capacity and precise flow control.

[0033] As a preferred embodiment of a sealed quantitative collection device for the recycling of shredded tobacco, at least one side of the housing is made of a transparent material.

[0034] This ensures that operators can visually observe the movement of various components inside the box and the dropping of tobacco shreds.

[0035] The beneficial effects of this utility model are:

[0036] The movable plate, driven by a driving component, rotates to the closed state. The movable end of the plate abuts against the inner wall of the housing, dividing the interior of the housing into an upper chamber and a lower chamber. The material inlet at the top of the housing is connected to the material outlet of the preceding separation device to receive the tobacco fragments discharged from the separation device. After entering the housing through the material inlet, the tobacco fragments fall onto the movable plate, i.e., into the upper chamber. The movable plate forms a sealing barrier to the material inlet, blocking the airflow exchange between the upper and lower chambers. The upper airflow cannot directly enter the lower part of the housing, thus avoiding the problem of secondary dust and tobacco fragments being thrown upwards due to pressure difference.

[0037] Once the upper chamber is filled to the preset full capacity, the drive unit rotates the movable plate to the open position. The shredded tobacco in the upper chamber quickly falls into the lower chamber along the inclined surface of the movable plate and finally gathers at the drop point in the center of the bottom wall of the box. The drive unit moves the movable plate to seal and separate the inside of the box, realizing batch and quantitative control of the shredded tobacco, ensuring the uniformity of the feed in the return link, and reducing the possibility of material blockage.

[0038] When the movable plate is closed, the positive pressure air inlet and the negative pressure suction inlet are also closed, and the lower chamber remains stationary, thus ensuring that the shredded tobacco settles stably to the discharge point. When the movable plate is open, the positive pressure air inlet and the negative pressure suction inlet open simultaneously. The airflow from the positive pressure air inlet blows the shredded tobacco in the lower chamber from the discharge point and sucks it away through the negative pressure suction inlet, thereby realizing the pneumatic return of the shredded tobacco. Through the opening and closing of the positive pressure air inlet and the negative pressure suction inlet, stable pneumatic return is maintained. The overall structure is simple and compact, with good adaptability and scalability. Attached Figure Description

[0049] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0050] like Figure 1 As shown, this utility model provides a sealed quantitative collection device for recycling shredded tobacco, including a box 1 and a movable plate 3. The box 1 is rectangular in shape. In this embodiment, the box 1 is a hollow cuboid structure, and the height of the box 1 is greater than its width. A material inlet 111 is provided at the top of the box 1, and a positive pressure air inlet 12 and a negative pressure suction inlet 13 are provided at the bottom of the box 1, respectively located on opposite sides of the bottom of the box 1. The movable plate 3 is a rectangular plate, with a rotating shaft on one side. The two ends of the rotating shaft are rotatably mounted on two opposite inner sidewalls of the box 1, and at least one end of the rotating shaft extends outside the box 1. The other end of the movable plate 3 is a movable end. A driving component 4 connected to the rotating shaft and driving the movable plate 3 to rotate is provided outside the box 1.

[0051] In addition, such as Figure 1 As shown, the top of the box 1 is open, and a top cover 11 is detachably connected to the opening. The material inlet 111 is located on the top cover 11. The top opening of the box 1 can be opened by directly removing the top cover 11, which facilitates the operator's maintenance and repair of the internal structure of the box 1, and also makes it easy to clean impurities and dirt inside the box 1. At least one side of the box 1 is made of transparent material, ensuring that the operator can directly observe the operation of the internal components of the box 1 and the falling of tobacco shreds.

[0052] Preferably, the two opposite sides of the movable plate 3 adjacent to its movable end are tightly fitted to the two opposite inner sidewalls of the box body 1, ensuring the sealing performance of the sealing plate.

[0053] Furthermore, a mounting base 2 is provided on the inner side wall of the housing 1, and a groove 122 is provided at the bottom of the mounting base 2 for the rotating shaft portion of the movable plate 3 to be embedded. The mounting base 2 fits tightly against the inner side wall of the housing 1, and the rotating shaft portion is embedded in the groove 122, which tightly covers the gap between the rotating shaft and the inner side wall of the housing 1 for rotational installation, so as to further ensure the sealing performance of the sealing plate.

[0054] It is understandable that the movable plate 3, except for the movable end, always remains in close contact with the inner wall of the box 1. When the movable end abuts against the inner wall of the box 1, it can ensure the sealing between the movable plate 3 and the box 1.

[0055] In this embodiment, the movable plate 3 has at least a closed state and an open state. When the movable plate 3 is in the closed state, the movable end of the movable plate 3 abuts against the inner wall of the box 1, so that the internal space of the box 1 is divided into an upper chamber and a lower chamber; when the movable plate 3 is in the open state, the movable end of the movable plate 3 tilts downward and rotates so that the upper chamber and the lower chamber are connected.

[0056] First, the drive unit 4 drives the movable plate 3 to rotate to the closed state. The movable end of the movable plate 3 abuts against the inner wall of the box 1 to divide the interior of the box 1 into an upper chamber and a lower chamber.

[0057] Then, the material inlet 111 at the top of the housing 1 is connected to the material outlet of the preceding separation device to receive the shredded tobacco discharged from the separation device. After entering the housing 1 through the material inlet 111, the shredded tobacco falls onto the movable plate 3, that is, into the upper chamber. The movable plate 3 forms a sealing barrier for the material inlet 111, blocking the airflow exchange between the upper and lower chambers. The upper airflow cannot directly enter the lower part of the housing 1, thereby avoiding the problem of secondary dust and shredded tobacco being thrown upwards due to pressure difference.

[0058] Secondly, a detection device is installed in the upper chamber to detect the amount of broken tobacco in the upper chamber. This detection device is electrically connected to a controller, which is in turn electrically connected to a drive unit. When the broken tobacco reaches the preset full-load state of the detection device, it sends a signal to the controller, which then sends a command to drive unit 4. Drive unit 4 then rotates the movable plate 3 to the open state. This design offers a high degree of automation. By adjusting the preset full-load value of the detection device, the amount of broken tobacco falling can be precisely controlled, ensuring quantitative collection and orderly release. Since the detection device is existing technology, it will not be described further here.

[0059] Furthermore, the shredded tobacco in the upper chamber falls rapidly into the lower chamber along the inclined surface 121 of the movable plate 3, and finally gathers at the material drop point at the center of the bottom wall of the box 1. By driving the movable plate 3 to move and seal the interior of the box 1 through the drive component 4, batch quantitative control of the shredded tobacco is achieved, ensuring the uniformity of the feed in the return link and reducing the possibility of material blockage.

[0060] Finally, the positive pressure air inlet 12 and the negative pressure suction inlet 13 are opened. The positive pressure airflow in the lower chamber is carried away and sucked away through the negative pressure suction inlet 13, achieving stable and efficient pneumatic return.

[0061] When the movable plate 3 is closed, the positive pressure air inlet 12 and the negative pressure suction inlet 13 are also closed, and the lower chamber remains stationary, thus ensuring that the shredded tobacco settles stably to the discharge point. When the movable plate 3 is open, the positive pressure air inlet 12 and the negative pressure suction inlet 13 open simultaneously. The airflow from the positive pressure air inlet 12 blows the shredded tobacco in the lower chamber from the discharge point and sucks it away through the negative pressure suction inlet 13, thereby realizing the pneumatic return of the shredded tobacco. Through the opening and closing of the positive pressure air inlet 12 and the negative pressure suction inlet 13, the pneumatic return is maintained stably. The overall structure is simple and compact, and has good adaptability and scalability.

[0062] It should be noted that, because the box 1 is a cuboid and its height is greater than its width, there is a gap between the movable end of the movable plate 3 and the inner bottom wall of the box 1 when the movable plate 3 is in the open state. When the movable plate 3 is rotated to a horizontal or nearly horizontal position, the movable end of the movable plate 3 remains pressed against the inner side wall of the box 1 to achieve a sealed fit between the movable plate 3 and the box 1. When the movable plate 3 is rotated to an inclined position, the extension direction of the movable end of the movable plate 3 points to the center of the inner bottom wall of the box 1, and the gap between the movable end and the inner bottom wall of the box 1 allows the shredded tobacco to smoothly enter the lower chamber. Through the cooperation of the movable plate 3, the discharge point, and the chamber, the bridging and accumulation of shredded tobacco in the box 1 is avoided, ensuring that the shredded tobacco can settle and be discharged smoothly.

[0063] Preferably, the driving component 4 includes a rotating block 41 and a telescopic cylinder 42. One end of the rotating block 41 is connected to a rotating shaft, and the end of the telescopic cylinder 42 is rotatably connected to the outer wall of the housing 1. The telescopic end of the telescopic cylinder 42 is rotatably connected to the other end of the rotating block 41. One side of the movable plate 3 forms a mechanical linkage with the telescopic cylinder 42 and the rotating block 41. The telescopic cylinder 42 drives the rotating block 41 to rotate, thereby realizing the rotation of the movable plate 3. The telescopic cylinder 42 drives the movable plate 3 to open or close, realizing rapid opening and closing, and achieving reliable control during the collection and release of tobacco shreds.

[0064] To reduce the accumulation of broken tobacco shreds, such as Figure 1As shown, the top surface of the mounting base 2 is set as an inclined surface 121, which slopes from one side of the housing 1 toward the center point of the housing 1. The tobacco shreds that fall onto the mounting base 2 will slide down the inclined surface 121 of the mounting base 2 onto the movable plate 3.

[0065] like Figure 1 As shown, a pipe 5 is detachably connected to the negative pressure suction port 13. The pipe 5, via the negative pressure suction port 13, transports the shredded tobacco to the downstream conveying chain, achieving pneumatic return of the shredded tobacco. A butterfly valve 51 is connected to the pipe 5. The opening and closing of the butterfly valve 51, the positive pressure air port 12, and the movable plate 3 follows a strict sequence: shredded tobacco is collected first, then airflow is returned, preventing the shredded tobacco from being disturbed by turbulence during release. The butterfly valve 51 has few components, is small in size and lightweight; when fully open, the thickness of the butterfly plate is the only resistance, resulting in a large flow capacity and precise flow control.

[0066] In summary, this embodiment has at least the following advantages:

[0067] 1. By sealing the movable plate 3 with the box body 1, the air convection between the material inlet 111 and the negative pressure suction port 13 is effectively blocked, preventing the settled tobacco shreds after vortex separation from being sucked up again, thus achieving stable collection and improving the purity of the separated material.

[0068] 2. The detection device detects that the material is full and triggers the opening of the movable plate 3 to release the broken tobacco in batches, avoiding the accumulation of broken tobacco in the box 1 at one time to form bridging or blockage, thus improving the stability of operation and the convenience of maintenance.

[0069] 3. After the movable plate 3 is closed, the positive pressure air port 12 blows up and cooperates with the butterfly valve 51 to form a positive and negative pressure coordinated pneumatic conveying, ensuring that the shredded tobacco can enter the pipe 5 quickly and evenly, improving the return efficiency and reducing residue.

[0070] 4. The opening and closing of the movable plate 3 and the actions of the positive pressure port 12 and butterfly valve 51 form a clear sequential logic, which realizes rapid and stable pressure difference between the release and return of tobacco fragments, and avoids loss of tobacco fragments due to airflow turbulence.

[0071] 5. The standardized design of the interface structure, such as the material inlet 111 and the negative pressure suction port 13, and the use of screws for detachable connection, can flexibly connect to different models of vortex separators and recycling conveyor links.

[0072] 6. By using a sealed structure and a quantitative batch return mechanism, the re-spreading of dust and the escape of dust from the box 1 are reduced, thereby improving the production site environment and reducing maintenance and cleaning costs.

[0073] 7. It comprehensively realizes the complete functional chain of "sealed and stable collection - quantitative batch release - positive and negative pressure coordinated return", which significantly improves the purity and return efficiency of tobacco shreds recovery and ensures the continuity and consistency of the cigarette feeding system.

[0074] 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 other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
