Description

Technical Field

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

[0002] The cigarette making and sealing unit is a crucial piece of equipment for processing tobacco into cigarettes, while also ensuring the quality of the cigarettes. To guarantee cigarette quality, the cigarette making and sealing unit is usually equipped with a dedicated tobacco stem collection device, which transports the separated tobacco stems through negative pressure pipelines to a dust removal system or a separate tobacco stem box for further processing.

[0003] Existing tobacco stem collection devices use negative pressure to feed tobacco stems into a negative pressure pipeline. A three-way reversing valve is installed on this pipeline; one end of the valve directs the tobacco stems into a centralized dust collection system, while the other end uses a centrifugal separator to throw the tobacco stems into a tobacco stem box. The negative pressure air is then fed into the main fan through the pipeline. However, existing tobacco stem collection devices have significant drawbacks:

[0004] Due to the use of a three-way reversing valve, a centrifugal separator, and multiple negative pressure pipelines, the entire device has become quite complex and bulky, which not only increases the manufacturing cost of the equipment but also makes maintenance and upkeep more difficult.

[0005] Therefore, how to provide a tobacco stem collection device with a simple structure and small size is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a tobacco stem collection device that solves the technical problems of complex structure and large size of existing tobacco stem collection devices.

[0007] To achieve the above objectives, this utility model provides a tobacco stem collecting device, comprising:

[0008] The tobacco stem box has a feed inlet on its side panel;

[0009] The tobacco stem collection box has an opening at the top and is located on the outside of the tobacco stem box. The outlet of the tobacco stem collection box is connected to the inlet of the tobacco stem box through an inlet pipe. The side plate of the tobacco stem collection box is provided with a first through hole.

[0013] Preferably, the sealing assembly includes:

[0014] A base plate, with a fan-shaped plate on one side of its upper end, and an installation port on the feed pipe. One side of the base plate is rotatably connected to the tobacco stem collection box through the installation port. The tobacco stem collection box is provided with an opening groove for the fan-shaped plate to rotate, and the fan-shaped plate is provided with a second through hole corresponding to the first through hole.

[0015] The driving component has a fixed end rotatably connected to a fixed base and an output end rotatably connected to a base plate to drive the base plate to rotate. When the driving component is in the first working position, the base plate is attached to the outside of the discharge port, and the second through hole communicates with the first through hole. When the driving component is in the second working position, the fan-shaped plate is attached to the inside of the first through hole, and the base plate is attached to the top of the mounting port.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] See Figures 1-2This application provides a tobacco stem collection device, comprising: a tobacco stem box 1 with an inlet on its side plate; a tobacco stem collection box 2 with an open top, located outside the tobacco stem box 1, the outlet of the tobacco stem collection box 2 being connected to the inlet of the tobacco stem box 1 via an inlet pipe 3, and a first through hole on the side plate of the tobacco stem collection box 2; a first negative pressure pipe 4, one end of which is connected to the first through hole and the other end of which is connected to a dust removal component; a second negative pressure pipe 5, one end of which is connected to the tobacco stem box 1 and the other end of which is connected to the first negative pressure pipe 4; and a sealing component located inside the tobacco stem collection box 2, having a first working position and a second working position. When the sealing component is in the first working position, the first through hole is open and the outlet is closed. When the sealing component is in the second working position, the first through hole is closed and the outlet is open.

[0031] Specifically, the tobacco stem box 1 is used to store collected tobacco stems. It has a feed inlet on its side plate to facilitate the entry of tobacco stems. The tobacco stem collection box 2 is located outside the tobacco stem box 1. Its upper end is open to facilitate the falling of tobacco stems. The bottom of the tobacco stem collection box 2 is provided with a discharge port, which is connected to the feed inlet of the tobacco stem box 1 through the feed pipe 3. Thus, the tobacco stems can be temporarily stored through the tobacco stem box 1.

[0032] One end of the first negative pressure pipe 4 is connected to the first through hole of the tobacco stem collection box 2, and the other end is connected to the dust removal component. Through the negative pressure, the tobacco stems and impurities in the tobacco stem collection box 2 are sucked in for further processing. The first negative pressure pipe 4 can generate negative pressure through a vacuum pump.

[0033] One end of the second negative pressure pipe 5 is connected to the tobacco stem box 1, and the other end is connected to the first negative pressure pipe 4 to form a negative pressure system, which facilitates the entry of tobacco stems in the tobacco stem collection box 2 into the tobacco stem box 1. When it is necessary to process the tobacco stems in the tobacco stem box 1, the negative pressure power can be increased so that the tobacco stems in the tobacco stem box 1 can be transported to the dust removal component through the second negative pressure pipe 5 and the first negative pressure pipe 4.

[0034] A sealing component is installed inside the tobacco stem collection box 2 to control the opening and closing of the first through hole and the discharge port. The sealing component has a first working position and a second working position. When the sealing component is in the first working position, the first through hole is open, and the negative pressure draws the tobacco stems from the tobacco stem collection box 2 into the first negative pressure pipe 4; at the same time, the discharge port is closed to prevent the tobacco stems from directly entering the feed pipe 3 from the discharge port. When the sealing component is in the second working position, the first through hole is closed, the first negative pressure pipe stops drawing in tobacco stems, and the discharge port is open, allowing the tobacco stems to enter the feed pipe 3 from the discharge port and then be transported to the tobacco stem box 1.

[0035] Therefore, this application provides a tobacco stem collection device that, through the cooperation of a sealing component, a first negative pressure pipe 4, and a second negative pressure pipe 5, enables tobacco stems in the tobacco stem collection box 2 to enter the dust removal component or the tobacco stem box 1. The overall device has a compact design, occupies little space, and is easy to install and maintain.

[0036] See Figures 3-4 Based on the above embodiments, the sealing assembly includes a base plate 6, a fan-shaped plate 7 is provided on one side of the upper end of the base plate 6, an installation port is provided on the feed pipe 3, and one side of the base plate 6 is rotatably connected to the tobacco stem collection box 2 through the installation port. The tobacco stem collection box 2 is provided with an opening groove for the fan-shaped plate 7 to rotate, and the fan-shaped plate 7 is provided with a second through hole 71 corresponding to the first through hole; a driving member 8, the fixed end of the driving member 8 is rotatably connected to the fixed seat, and the output end is rotatably connected to the base plate 6 to drive the base plate 6 to rotate. When the driving member 8 is in the first working position, the base plate 6 is attached to the outside of the discharge port, and the second through hole 71 communicates with the first through hole. When the driving member 8 is in the second working position, the fan-shaped plate 7 is attached to the inside of the first through hole, and the base plate 6 is attached to the top of the installation port.

[0037] Specifically, a fan-shaped plate 7 is provided on the side of the end face of the base plate 6 facing the first through hole.

[0038] The sector plate 7 is provided with a second through hole 71 corresponding to the first through hole. When the sector plate 7 is rotated to a specific position, the second through hole 71 is aligned with the first through hole, thus achieving communication.

[0039] One side of the base plate 6 is rotatably connected to the tobacco stem collection box 2 through the mounting port, ensuring that the base plate 6 and the fan-shaped plate 7 can rotate smoothly. The tobacco stem collection box 2 is provided with an opening slot for the fan-shaped plate 7 to rotate, ensuring that the fan-shaped plate 7 will not be obstructed during rotation.

[0040] The driving component 8 is used to drive the rotation of the base plate 6 and the sector plate 7. The fixed end of the driving component 8 is rotatably connected to the fixed seat, and the output end is rotatably connected to the base plate 6. By adjusting the output end of the driving component 8, the rotation angle of the base plate 6 and the sector plate 7 can be controlled, thereby realizing the switching of the sealing component between different working positions.

[0041] First job position:

[0042] When the drive component 8 extends to the first working position Figure 3 As shown, the base plate 6 is attached to the outside of the discharge port, completely sealing the discharge port. At the same time, the second through hole 71 on the fan-shaped plate 7 is aligned with and connected to the first through hole, and the negative pressure can draw the tobacco stems in the tobacco stem collection box 2 into the first negative pressure pipe 4.

[0043] Second job position:

[0044] When the drive unit 8 retracts to the second working position Figure 4As shown, the fan-shaped plate 7 is attached to the inside of the first through hole, completely sealing the first through hole. At the same time, the base plate 6 rotates and is attached to the top of the installation port. At this time, the discharge port is in the open state, allowing the tobacco stems to enter the feed pipe 3 from the discharge port and then be transported to the tobacco stem box 1.

[0045] Specifically, the size of the base plate 6 is larger than the size of the outlet of the tobacco stem collection box 2, ensuring that the base plate 6 can completely and effectively cover and seal the outlet when the sealing component is in its first working position.

[0046] Based on the above embodiments, a hinge 9 is also included, one end of which is connected to the base plate 6, and the other end is connected to the outer wall of the tobacco stem collection box 2.

[0047] In other words, one end of the hinge 9 is connected to the base plate 6, and the other end is connected to the outer wall of the tobacco stem collection box 2, allowing the base plate 6 and the fan-shaped plate 7 to rotate smoothly within the tobacco stem collection box 2 at a certain angle range.

[0048] Hinges 9 should be made of corrosion-resistant and wear-resistant materials to ensure that they do not fail due to environmental factors or wear during long-term use.

[0049] Based on the above embodiments, a connecting rod 10 is also included, one end of which is rotatably connected to the output end of the driving component 8, and the other end is connected to the bottom surface of the base plate 6.

[0050] Specifically, the connecting rod 10 serves as a transmission component, with one end rotatably connected to the output end of the drive component 8 and the other end connected to the bottom surface of the base plate 6. By transmitting driving force, the base plate 6 and the sector plate 7 can rotate smoothly and accurately to the required working position.

[0051] Specifically, the length and shape of the connecting rod 10 should be selected according to the specific positions of the sealing assembly and the drive component 8 to ensure stability and accuracy during transmission.

[0052] Specifically, the connecting rod 10 should be made of high-strength, corrosion-resistant material to withstand the load during transmission and maintain long-term reliability.

[0053] Based on the above embodiments, the driving component 8 is a cylinder or an electric push rod; the tobacco stem collection box 2 and the feeding pipe 3 are an integral part.

[0054] In this embodiment, the driving component 8 is a cylinder, and the piston rod of the cylinder can be directly connected to the connecting rod 10. The rotation of the base plate 6 and the sector plate 7 is driven by the change of air pressure, which can achieve precise position control.

[0055] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0056] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
