Description

Technical Field

[0001] This utility model relates to the technical field of cigarette production equipment, and in particular to a filter rod production equipment. Background Technology

[0002] To meet diverse consumer needs, existing cigarette products typically incorporate flavoring powders during the cigarette manufacturing process. These powders enhance the aroma and flavor during smoking, thereby improving the consumer's smoking experience.

[0003] In existing technologies, powder adding equipment is typically used to transport powder, while the filter rod conveyor line is located below the powder adding equipment. When the filter rod conveyor line transports the filter rods to below the discharge position of the powder adding equipment, the powder in the powder adding equipment falls into the filter rods accordingly, thereby achieving automatic powder adding.

[0004] The powder adding equipment is equipped with a feeding mechanism, such as the feeding mechanism disclosed in publication number CN221140323U. The existing feeding mechanism usually includes a material tray and a material plate. The material tray is equipped with a material trough, and the bottom of the material tray is provided with a feeding hole that communicates with the material trough. The material plate can move relative to the material tray to open and close the feeding hole, and the powder can flow out of the material trough from the opened feeding hole, thereby realizing quantitative feeding.

[0005] However, when the equipment stops, the high-speed rotating powder will accumulate in a certain place on the material tray due to the sudden stop, causing the material to be fed too aggressively below that place when the machine is restarted, or even overflow, affecting the quantitative feeding effect.

[0057] This utility model provides a filter rod production equipment, which includes a powder adding device and a filter rod conveying line; the powder adding device includes a feeding mechanism and a feeding device; the feeding mechanism includes a feeding tray, a material plate, a material plate driving mechanism, and a tray cover plate; the feeding tray is provided with a material trough for receiving powder, and the bottom of the feeding tray has a feeding hole communicating with the material trough; the material plate is disposed on the bottom side of the feeding tray and corresponds to the feeding hole, and the material plate can move radially along the feeding tray to open or close the feeding hole; the material plate driving mechanism is connected to the material plate to drive the material... The plate moves radially along the feeding tray; the tray cover includes a tray body and a suction element; the tray body covers the top of the feeding tray; the suction element is located on the inner side of the tray body and extends into the material trough; the suction element is connected to a negative pressure suction device, which provides negative pressure to the suction element to suction the powder accumulated in the material trough; the feeding device is located below the discharge position of the feeding mechanism to receive the powder falling from the feeding mechanism; the filter rod conveyor is located below the discharge position of the feeding device to receive the powder falling from the feeding device. The filter rod production equipment is equipped with a suction component, which is located on the disc body above the material trough. When the equipment needs to be stopped, the negative pressure suction device provides negative pressure to the suction component, thereby sucking up the powder accumulated in a local area of ​​the material trough to a certain extent. This avoids excessive powder accumulation, which would affect the feeding effect when restarting the machine. This better ensures the accuracy of the quantitative feeding of the feeding disc in the filter rod production equipment and ensures the quantitative feeding effect.

[0058] Please refer to the following: Figures 1 to 6 This embodiment provides a filter rod production equipment, which is mainly used to solve the technical problem that when the equipment is stopped, the powder tends to accumulate in a local area of ​​the feeding tray, affecting the amount of material to be fed next time.

[0059] The filter rod production equipment includes a powder adding device and a filter rod conveying line 10. The powder adding device includes a feeding mechanism and a feeding device. The feeding mechanism includes a feeding tray 20, a material plate 30, a material plate driving mechanism 40, and a tray cover plate 50. The feeding tray 20 is provided with a material trough 21 for receiving powder, and the bottom of the feeding tray 20 has a feeding hole 22 communicating with the material trough 21. The material plate 30 is disposed on the bottom side of the feeding tray 20 and corresponds to the feeding hole 22. The material plate 30 can move radially along the feeding tray 20 to open or close the feeding hole 22. When the material plate 30 closes the feeding hole 22, the powder in the material trough 21 cannot be fed through the feeding hole 22; while when the material plate 30 opens the feeding hole 22, the powder in the material trough 21 can be smoothly fed outward through the feeding hole 22. The material plate driving mechanism 40 is connected to the material plate 30 and is used to drive the material plate 30 to move radially along the feed tray 10.

[0060] The material tray cover 50 includes a tray body 51 and a suction element 52. The tray body covers the top of the discharge tray 20, and the suction element 52 is disposed on the inner side of the tray body 51 and extends into the material trough 21. The inner side of the tray body 51 refers to the side of the tray body 51 closest to the discharge tray 20. The suction element 52 is connected to a negative pressure suction device, which provides negative pressure to the suction element 52 to suction the powder accumulated in the material trough 21. Specifically, the negative pressure suction device can be any device that can provide suction force, such as an air pump.

[0061] The feeding device is located below the discharge position of the feeding mechanism and is used to collect the powder falling from the feeding mechanism. When the powder falls from the discharge hole 22, the feeding device collects the falling powder. The feeding device can adopt any existing conveying structure, such as the device disclosed in publication number CN115581314A, etc., which will not be described in detail here.

[0062] The filter rod conveyor line 10 is located below the discharge position of the feeding device to receive the powder falling from the feeding device. The feeding unit in the feeding device receives the powder falling from the feeding mechanism, and then the feeding unit moves to the discharge position to drop the received powder. The falling powder falls into the filter rods conveyed on the filter rod conveyor line 10, thereby realizing the automatic addition of powder to the filter rods.

[0063] Understandably, in the existing technology, when the equipment stops, the powder rotating at high speed in the feeding tray will accumulate in a certain place in the trough due to the sudden stop. This will cause the material to be fed too aggressively below that place when the machine is restarted, or even overflow, affecting the quantitative feeding effect and ultimately resulting in an excessive amount of powder being fed into the filter rod.

[0064] In this embodiment, a suction element 52 is provided on the disc 51, extending from the top of the material trough 21 into the trough 21. When the equipment needs to be stopped, the negative pressure suction device can be turned on first, and then the feeding disc 20 can continue to rotate one revolution. This allows the suction element 52 to extract excess powder accumulated in a portion of the material trough 21, thus preventing excessive accumulation of powder in the trough 21 and affecting the quantitative feeding effect during the next startup. This better ensures that the powder ultimately fed into the filter rod is not excessive. Furthermore, the suctioned powder can be reused, reducing powder costs. The specific suction force of the negative pressure suction device can be selected according to actual needs, ensuring that only excess accumulated powder is suctioned away during the suction process, rather than all the powder in the material trough 21.

[0065] Preferably, in one embodiment, the material plate driving mechanism 40 is a cam disk, and the material plate driving mechanism 40 has continuous cam grooves 41, wherein the continuous cam grooves 41 refer to the cam grooves 41 being connected end to end, thereby forming a complete ring-like structure, and the component can continuously move in the same direction in the cam grooves 41. The sliding section of the material plate 30 is slidably disposed in the cam groove 41. By sliding the sliding section to different positions in the cam groove 41, the material plate 30 can be driven to move radially to open or close the discharge hole 22. For example, when the sliding section slides to a relatively concave area in the cam groove 41, it drives the material plate 30 to move radially inward, thereby opening the discharge hole 22; when the sliding section slides to a relatively convex area in the cam groove 41, it drives the material plate 30 to move radially outward, thereby closing the discharge hole 22. The discharge mechanism also includes a rotary drive member, which is connected to the discharge disk 20 or the material plate driving mechanism 40. The rotary drive component drives the relative rotation between the feeding tray 20 and the material plate drive mechanism 40, thereby causing the material plate 30 to slide in the cam groove 41, thus driving the material plate 30 to move radially. The rotary drive component can be connected to the feeding tray 20 to drive its rotation, thereby better fixing the feeding position during feeding. The rotary drive component can also be connected to the material plate drive mechanism 40 to drive its rotation, allowing for multi-point feeding during feeding. Specifically, the rotary drive component can be a motor.

[0066] Preferably, in one embodiment, the filter rod production equipment further includes a powder recovery mechanism 60, which is disposed on the side of the filter rod conveyor line 10, and the powder recovery port 61 of the powder recovery mechanism 60 is located behind the receiving position 11 of the filter rod conveyor line 10. The receiving position 11 is located directly below the discharge position of the feeding device, and the powder falling from the feeding device falls into the filter rod at the receiving position 11. The powder recovery port 61 is located behind the receiving position 11 with reference to the conveying direction of the filter rod. When the filter rod is conveyed on the filter rod conveyor line 10, it first passes the receiving position 11 and then passes the area where the powder recovery port 61 is located. The powder recovery mechanism 60 is connected to a negative pressure device, which provides negative pressure to the powder recovery mechanism 60 to suck up excess powder on the filter rod conveyor line 10. Ideally, the powder falling from the feeding device should all enter the filter rods. However, due to various factors, some of the powder falling from the feeding device may scatter around the filter rods, and it may also scatter during the conveying process of the filter rods on the conveyor line 10. The powder recovery mechanism 60 can be used to extract the powder scattered around the filter rods. Similarly, the negative pressure device can be any device that provides suction force, such as an air pump. Furthermore, the specific suction force of the negative pressure device can be selected according to actual needs, ensuring that only the scattered powder is extracted during the extraction process, without extracting the powder from the filter rods. Similarly, the extracted powder can be reused, reducing powder costs.

[0067] Preferably, in one embodiment, the powder recovery mechanism 60 includes a powder recovery box 62, a powder suction section 63, and an air amplifier 64. The powder recovery box 62 is used to store the recovered powder. The powder recovery port 61 is disposed on the powder suction section 63. The air amplifier 64 is disposed between the powder recovery box 62 and the powder suction section 63 and is connected to the negative pressure device. The air amplifier 64 further improves the powder suction effect.

[0068] Preferably, in one embodiment, the powder recycling box 62 includes a box body 621 and a box body cover 622. The box body 621 is provided with a storage cavity 6211 for storing powder, and the box body cover 622 is detachably disposed on the top of the box body 621 and covers the storage cavity 6211. By providing the detachable box body cover 622, the box body 621 can be easily maintained. The powder suction part 63 includes a body 631 and a suction part cover 632. The body 631 is provided with a powder flow cavity 6311, which communicates with the powder recycling port 61. The suction part cover 632 is detachably disposed on the top of the body 631 and covers the powder flow cavity 6311. Similarly, by providing the detachable suction part cover 632, the body 631 can be easily maintained. The air amplifier 64 is connected to the storage cavity 6211 and the powder flow cavity 6311 respectively.

[0069] By designing the powder recovery port 61 near the smoke chamber outlet, the powder scattered around the smoke chamber can be effectively sucked up, and the powder can be quickly collected in the powder recovery box 62 by the air amplifier 64.

[0070] Preferably, in one embodiment, the powder recovery port 61 is elongated, and the powder recovery port 61 is arranged along the conveying direction of the filter rod conveyor line 10. That is, in this embodiment, the cross-sectional shape of the powder recovery port 61 is elongated, and it is arranged along the conveying direction of the filter rod conveyor line 10, thereby further ensuring the suction effect of excess powder.

[0071] Preferably, in one embodiment, the suction component 52 includes an mounting portion 521 and a suction portion 522, with the mounting portion 521 disposed on the inner side of the disc body 51. The suction portion 522 is connected to the mounting portion 521 and has a suction port 5221, extending into the material trough 21. The specific length of the suction portion 522 extending into the material trough 21 can be selected according to actual needs, as long as it can suction excess accumulated powder without obstructing normal powder. The disc body 51 has a through-hole corresponding to the suction port 5221, and the negative pressure suction device communicates with the suction port 5221.

[0072] Preferably, in one embodiment, the tray cover 50 further includes a feeding component 53, which is disposed inside the tray body 51 and extends into the material trough 21. The feeding component 53 is connected to an external feeding device to feed powder into the material trough 21. With the feeding component 53, when powder needs to be added to the unloading tray 20, it is not necessary to open the tray cover 50 separately, and automatic powder addition can be achieved, further improving production efficiency.

[0073] Preferably, in one embodiment, the feeding tray 20 is provided with a partition 23, which divides the material trough 21 into a first material trough 211 and a second material trough 212. It is understood that existing feeding trays only have one material trough, which can only meet the feeding needs of one type of powder and cannot feed different types of powder. In this embodiment, the feeding tray 20 is provided with at least a first material trough 211 and a second material trough 212, thus accommodating at least two types of powder simultaneously. The partition 23 effectively separates the two types of powder, preventing accidental mixing. Simultaneously, the first material trough 211 and the second material trough 212 can each be provided with a corresponding feeding hole 22, allowing the two types of powder to be discharged outwards. The feeding member 53 has multiple (at least two) feeding ports 531, and each of the first material trough 211 and the second material trough 212 extends into one of the feeding ports 531. In other words, the feeding component 53 can feed materials into both the first material trough 211 and the second material trough 212. Specifically, in one embodiment, there are two feeding ports 531, namely a first feeding port 5311 and a second feeding port 5312. The first feeding port 5311 extends into the first material trough 211, and the second feeding port 5312 extends into the second material trough 212. The channels between the first feeding port 5311 and the second feeding port 5312 can be isolated from each other, thereby preventing powder mixing during the feeding process.

[0074] The above description is merely an embodiment of this utility model. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this utility model, but these improvements all fall within the protection scope of this utility model.
