Description

Technical Field

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

[0002] Cigarette production generates tobacco dust, which is lightweight and prone to static electricity. This dust can adhere to cigarette-making equipment or drift into the production environment, affecting the normal operation of the equipment and causing pollution. Therefore, it is necessary to recycle the tobacco dust.

[0003] Existing cigarette manufacturing equipment typically uses a tobacco dust collection device to collect tobacco dust. This device has a discharge port connected to a briquetting machine, through which the collected tobacco dust is conveyed to the briquetting machine for compression. To ensure the tobacco dust falls smoothly into the briquetting machine, a pusher plate is usually installed inside the tobacco dust collection device. A motor-driven pusher plate pushes the tobacco dust to the discharge port, allowing it to smoothly enter the briquetting machine.

[0004] In existing tobacco dust collection devices, tobacco dust tends to get stuck between the inner wall of the device and the push plate during collection. Due to friction, the push plate becomes stuck on the inner wall of the collection device and cannot move, thus failing to push the tobacco dust to the discharge port and even damaging the motor. Utility Model Content

[0005] The purpose of this utility model is to provide a smoke dust collection device that uses a telescopic mechanism to drive the pusher to move, thereby preventing the pusher from getting stuck on the inner wall of the dust collection chamber, ensuring that the pusher can work normally, and preventing damage to the drive mechanism 3.

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

[0007] A smoke dust collection device is provided, comprising:

[0008] A dust collection bin, wherein a feed inlet is provided at the top of the dust collection bin and a discharge outlet is provided at the bottom of the dust collection bin;

[0009] A telescopic mechanism is provided inside the dust collection chamber;

[0010] A drive mechanism is fixed to the dust collection bin and is connected to the telescopic mechanism. The drive mechanism can drive the telescopic mechanism to perform circular motion in the horizontal plane.

[0011] A pushing component is connected to the telescopic mechanism and can rotate synchronously with the telescopic mechanism. The pushing component corresponds to the discharge port, and a gap is provided between the pushing component and the side wall of the dust collection bin.

[0012] Optionally, the pusher is a triangular prism with side edges extending vertically, one of which faces the side wall of the dust collection chamber and is clearance-fitted with the side wall of the dust collection chamber.

[0013] Optionally, the pusher is an isosceles triangular prism, and the side edge corresponding to the apex angle of the pusher faces the side wall of the dust collection bin, and the telescopic mechanism is connected to the side wall opposite to the apex angle of the pusher.

[0014] Optionally, the telescopic mechanism includes an elastic element, the driving mechanism includes a motor and an output shaft, the motor is capable of driving the output shaft to rotate in a horizontal direction, the first end of the elastic element is fixed relative to the output shaft, and the second end of the elastic element is fixed relative to the pushing element.

[0015] Optionally, the telescopic mechanism further includes a support rod connected to the output shaft, the pusher being slidably connected to the support rod, and the first end of the elastic member being fixed relative to the support rod.

[0016] Optionally, the support rod includes a large-diameter section, a small-diameter section, and a stepped surface. The large-diameter section is connected to the output shaft, the elastic element is disposed in the small-diameter section, and the first end of the elastic element abuts against the stepped surface.

[0017] Optionally, the telescopic mechanism further includes a connector slidably connected to the small diameter section, the pusher connected to the connector, and the second end of the elastic member abutting against the connector.

[0018] Optionally, the connector is cylindrical and is fitted onto the small-diameter section.

[0019] Optionally, there are two discharge ports, which are spaced apart on the bottom wall of the dust collection bin.

[0020] Optionally, the smoke collection device further includes a dust collector connected to the drive mechanism, and the telescopic mechanism connected to the dust collector.

[0021] The beneficial effects of this utility model are:

[0022] This utility model provides a tobacco dust collection device, which includes a dust collection bin, a telescopic mechanism, a drive mechanism, and a pushing component. The dust collection bin has an inlet at the top and an outlet at the bottom. Tobacco dust enters the dust collection bin through the inlet and falls into the briquetting machine through the outlet. The telescopic mechanism is located inside the dust collection bin, and the drive mechanism is fixed to the dust collection bin. The drive mechanism drives the telescopic mechanism to perform circular motion in a horizontal plane. The pushing component is connected to the telescopic mechanism and can rotate synchronously with it. The pushing component corresponds to the outlet, and a gap is provided between the pushing component and the side wall of the dust collection bin to avoid interference. Under normal conditions, the drive mechanism drives the telescopic mechanism to rotate in a horizontal plane, which in turn drives the pushing component to rotate in a horizontal plane. The rotation of the pushing component pushes the tobacco dust to the outlet, where it falls into the briquetting machine under gravity. When soot is trapped between the inner wall of the dust collection bin and the pushing component, the pushing component, moving in a circular motion in the horizontal plane, experiences a centripetal force. This causes the pushing component to press against the telescopic mechanism, compressing it. The pushing component then moves away from the inner wall of the dust collection bin, causing the soot trapped between the inner wall and the pushing component to fall onto the bottom wall of the dust collection bin. This allows the pushing component to continue moving. At this point, the telescopic mechanism returns to its normal operating state, the pushing component resets to align with the discharge port, and the telescopic mechanism continues to drive the pushing component in a circular motion, scraping the soot that has fallen onto the bottom wall of the dust collection bin into the discharge port. The soot collection device uses the telescopic mechanism to move the pushing component, preventing it from getting stuck on the inner wall of the dust collection bin, ensuring the pushing component can work normally, and preventing damage to the drive mechanism. Furthermore, the soot collection device has a simple structure and is easy to install. Attached Figure Description

[0027] 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, and not the entire structure.

[0028] 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.

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.

[0030] 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.

[0031] like Figure 1 and Figure 2As shown, this embodiment provides a smoke dust collection device, which includes a dust collection bin 1, a telescopic mechanism 2, a drive mechanism 3, and a pusher 4. The dust collection bin 1 has an inlet 11 at its top and an outlet 12 at its bottom. Smoke dust enters the dust collection bin 1 through the inlet 11 and falls into the briquetting machine through the outlet 12. The telescopic mechanism 2 is located inside the dust collection bin 1, and the drive mechanism 3 is fixed to the dust collection bin 1. The drive mechanism 3 is connected to the telescopic mechanism 2 and drives the telescopic mechanism 2 to perform circular motion in a horizontal plane. The pusher 4 is connected to the telescopic mechanism 2 and can rotate synchronously with it. The pusher 4 corresponds to the outlet 12, and a gap is provided between the pusher 4 and the side wall of the dust collection bin 1 to avoid interference between the pusher 4 and the side wall of the dust collection bin 1.

[0032] Under normal conditions, the drive mechanism 3 drives the telescopic mechanism 2 to rotate in the horizontal plane. The telescopic mechanism 2 drives the pusher 4 to rotate in the horizontal plane. The rotation of the pusher 4 pushes the tobacco dust to the discharge port 12. Under the action of gravity, the tobacco dust falls into the briquetting machine. When the tobacco dust is trapped between the inner wall of the dust collection bin 1 and the pusher 4, the pusher 4 will be subjected to centripetal force as it makes circular motion in the horizontal plane. This causes the pusher 4 to squeeze the telescopic mechanism 2, which is compressed. The pusher 4 will move away from the inner wall of the dust collection bin 1, causing the tobacco dust trapped between the inner wall of the dust collection bin 1 and the pusher 4 to fall onto the bottom wall of the dust collection bin 1, allowing the pusher 4 to continue moving. At this time, the telescopic mechanism 2 returns to its normal working state, and the pusher 4 resets so that the pusher 4 corresponds to the discharge port 12. The telescopic mechanism 2 continues to drive the pusher 4 to make circular motion, scraping the tobacco dust that has fallen onto the bottom wall of the dust collection bin 1 into the discharge port 12. The dust collection device uses a telescopic mechanism 2 to move the pushing component 4, preventing the pushing component 4 from getting stuck on the inner wall of the dust collection chamber 1, ensuring the normal operation of the pushing component 4, and preventing damage to the drive mechanism 3. At the same time, the dust collection device has a simple structure and is easy to install.

[0033] Specifically, the dust collection bin 1 is a cylindrical structure with its axis extending vertically. The top of the dust collection bin 1 is an opening, namely the feed inlet 11, and the discharge outlet 12 is located on the bottom wall of the dust collection bin 1. The drive mechanism 3 is fixed to the center of the bottom wall of the dust collection bin 1 and is partially located inside the dust collection bin 1 to connect with the telescopic mechanism 2. The telescopic mechanism 2 can rotate around the center of the bottom wall of the dust collection bin 1, driving the pusher 4 to rotate. The bottom of the pusher 4 is in contact with the bottom wall of the dust collection bin 1 and can rotate relative to the bottom wall of the dust collection bin 1, so that it can push the smoke dust falling on the bottom wall of the dust collection bin 1 to the discharge outlet 12.

[0034] Optionally, there are two discharge ports 12, which are spaced apart on the bottom wall of the dust collection bin 1 to make the smoke falling into the briquetting machine more even and increase the speed at which the smoke falls, thus avoiding excessive smoke in the dust collection bin 1.

[0035] Specifically, the discharge port 12 is a circular hole. The two discharge ports are symmetrically arranged about the center of the bottom wall of the dust collection bin 1 to prevent the smoke dust falling into the briquetting machine from accumulating on one side. In other embodiments, multiple discharge ports 12 can also be provided, with multiple discharge ports 12 arranged circumferentially around the bottom wall of the dust collection bin 1.

[0036] Optionally, the pusher 4 is a triangular prism with its side edges extending vertically. One side edge faces the side wall of the dust collection chamber 1 and is clearance-fitted with the side wall of the dust collection chamber 1. Due to the small area of ​​the side edge, smoke is less likely to get stuck between the inner wall of the dust collection chamber 1 and the side edge. Furthermore, the angle formed between the sides of the triangular prism makes it easier for the smoke between the inner wall of the dust collection chamber 1 and the side edge to slide off, reducing the possibility of the pusher 4 getting stuck in the dust collection chamber 1 and improving the service life of the pusher 4. If smoke is stuck between the side edge and the inner wall of the dust collection chamber 1, the amount of smoke is also small. The telescopic mechanism 2 drives the pusher 4 to move, making it easier for the smoke stuck between the side edge and the inner wall of the dust collection chamber 1 to fall off.

[0037] Furthermore, the pusher 4 is an isosceles triangular prism, which has a more stable structure. The side edge corresponding to the apex of the pusher 4 faces the side wall of the dust collection bin 1, and the telescopic mechanism 2 is connected to the side wall opposite to the apex of the pusher 4, thereby improving the connection stability between the telescopic mechanism 2 and the pusher 4.

[0038] Specifically, the two sidewalls adjacent to the top corner of the pusher 4 are symmetrically arranged about the line connecting the side edge corresponding to the top corner of the pusher 4 and the center of the bottom wall of the dust collection bin 1. One of the two sidewalls adjacent to the top corner of the pusher 4 is inclined to push the smoke, which can disperse the pressure of the smoke on the pusher 4.

[0039] Optionally, the smoke collection device also includes a dust collector 5, which is connected to the drive mechanism 3. A telescopic mechanism 2 is connected to the dust collector 5. The drive mechanism 3 drives the dust collector 5 to rotate, thereby throwing the smoke that falls into the dust collection bin 1 towards the side closest to the inner wall of the dust collection bin 1, reducing the density of the smoke and facilitating the pushing component 4 to push the smoke. Simultaneously, the telescopic mechanism 2 is connected to the dust collector 5, and the dust collector 5 drives the telescopic mechanism 2 to perform circular motion, facilitating the connection between the telescopic mechanism 2 and the drive mechanism 3. Specifically, the dust collector 5 has a conical structure, with its apex facing upwards to prevent smoke from falling onto the top of the dust collector 5.

[0040] Optionally, the telescopic mechanism 2 includes an elastic element 21, and the drive mechanism 3 includes a motor 31 and an output shaft 32. The motor 31 can drive the output shaft 32 to rotate in the horizontal direction. The first end of the elastic element 21 is fixed relative to the output shaft 32, and the second end of the elastic element 21 is fixed relative to the pusher 4. When the soot is trapped between the inner wall of the dust collection bin 1 and the pusher 4, the pusher 4 squeezes the elastic element 21, compressing the elastic element 21 and causing the pusher 4 to move away from the inner wall of the dust collection bin 1. The soot trapped between the inner wall of the dust collection bin 1 and the pusher 4 falls off, allowing the pusher 4 to continue moving, and the elastic element 21 returns to its original shape.

[0041] Specifically, the motor 31 is located on the outside of the dust collection bin 1. A through hole is provided on the bottom wall of the dust collection bin 1, and the output shaft 32 passes through the through hole and extends into the dust collection bin 1. The output shaft 32 extends vertically, and the motor 31 drives the output shaft 32 to rotate. A fixed groove extending vertically is provided at the center of the bottom of the material distributor 5, and the output end of the output shaft 32 is engaged in the fixed groove, thereby driving the material distributor 5 to rotate. The elastic element 21 is a spring; in other embodiments, the elastic element 21 can also be a sleeve made of elastic material. In other embodiments, the telescopic mechanism 2 can also be a cylinder and a push rod. The cylinder is connected to the output shaft 32, and the push rod is connected to the pushing member 4. The push rod can extend and retract, thereby driving the pushing member 4 to move.

[0042] Optionally, the telescopic mechanism 2 further includes a support rod 22, which is connected to the output shaft 32. The pusher 4 is slidably connected to the support rod 22, and the first end of the elastic member 21 is fixed relative to the support rod 22. By providing the support rod 22, the stability of the connection between the elastic member 21, the pusher 4, and the output shaft 32 is improved. Specifically, one end of the support rod 22 is engaged with the side wall of the feeder 5, and the other end extends horizontally. The elastic member 21 is sleeved on the support rod 22.

[0043] Furthermore, the support rod 22 includes a large-diameter section, a small-diameter section, and a stepped surface. The large-diameter section is connected to the output shaft 32, and the elastic element 21 is disposed on the small-diameter section. The first end of the elastic element 21 abuts against the stepped surface. Specifically, the elastic element 21 is sleeved on the small-diameter section and abuts against the stepped surface to restrict the position of the elastic element 21.

[0044] Optionally, the telescopic mechanism 2 further includes a connector 23, which is slidably connected to the small-diameter section. The pusher 4 is connected to the connector 23, and the sliding of the connector 23 can drive the pusher 4 to slide relative to the support rod 22. The second end of the elastic member 21 abuts against the connector 23 to limit the position of the elastic member 21.

[0045] Furthermore, the connector 23 is cylindrical and is fitted onto the smaller diameter section, making the connection between the connector 23 and the support rod 22 more stable and facilitating installation. Specifically, the connector 23 is fitted onto the end of the support rod 22 away from the drive mechanism 3. In addition, the connector 23 is snapped and fixed to the pusher 4.

[0046] 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.
