Technical Field

[0001] This invention relates to the field of granular heated non-combustible cigarette production technology, specifically to a pneumatic cigarette conveying device, method, and cigarette production line. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] The production line for granular heated tobacco products needs to transport multiple cigarettes from the mold to the collection device. The cigarettes delivered from the mold are vertical, while the collection device needs to receive the horizontal ones. Currently, an electric tilting conveyor is used to transport the cigarettes from the mold to the collection device. The vertical cigarettes fall from the mold onto the electric tilting conveyor, which then tilts them 90° to turn them into horizontal ones before sending them to the collection device. However, the current electric tilting conveyor has two drawbacks: firstly, its complex structure increases equipment investment; secondly, the tilting process takes a long time, resulting in long cigarette transport time, low work efficiency, and affecting the overall production progress of the granular heated tobacco product line. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a pneumatic cigarette conveying device, method and cigarette production line, which has a simple structure, shortens the conveying time of cigarettes from the mold to the collection device and improves work efficiency.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] In a first aspect, embodiments of the present invention provide a pneumatic cigarette delivery device, including a cigarette distribution block, a cigarette guide block fixed to the bottom surface of the cigarette distribution block, the cigarette distribution block having a plurality of first cigarette channels for receiving cigarettes falling from a mold, the cigarette guide block having a plurality of second cigarette channels, the second cigarette channels communicating with corresponding first cigarette channels, the bottom surface of the cigarette guide block having a guide tube communicating with the second cigarette channels, each second cigarette channel being connected to an air blowing channel opened on the cigarette guide block, the air blowing channel being set at a set acute angle with the second cigarette channels and the height of the air inlet side being higher than the height of the air outlet side, the air blowing channel communicating with the air inlet channel opened on the cigarette distribution block, the air inlet channel being connected to an air source through an air pipe, and the bottom end of the guide tube being connected to a bend to change the vertical cigarette to a horizontal state.

[0007] Optionally, the first cigarette channel includes a first channel section and a second channel section. The top end of the first channel section extends to the top surface of the cigarette gas distribution block, and the bottom end communicates with the top end of the second channel section. The bottom end of the second channel section extends to the bottom surface of the cigarette gas distribution block, and the top cross-sectional area of ​​the first channel section is larger than the bottom cross-sectional area.

[0008] Optionally, the second channel portion is coaxially arranged with the second cigarette channel, and the diameter of the second channel portion is smaller than the diameter of the second cigarette channel.

[0009] Optionally, the air intake channel adopts multiple air intake slots set on the bottom surface of the cigarette air distribution block. The same air intake slot is connected to multiple corresponding air blowing channels, and the air intake slot is connected to the air intake hole set on the cigarette air distribution block or the cigarette guide block.

[0010] Optionally, multiple sets of the first and second cigarette channels are provided, with two rows in each set. The corresponding first and second cigarette channels are connected. The two rows of first cigarette channels in the same set are staggered, and the two rows of second cigarette channels in the same set are staggered.

[0029] Example 1

[0030] This embodiment provides a pneumatic cigarette conveying device for horizontally feeding vertically dropped cigarettes from a mold into a collection device during the production of granular heated non-combustible cigarettes.

[0031] like Figures 1-2 As shown, the conveying device includes a cigarette gas distribution block 2, and a cigarette guide block 1 is fixed to the bottom surface of the cigarette gas distribution block 2 by bolts.

[0032] like Figures 3-4 As shown, the cigarette distribution block 2 is provided with multiple sets of first cigarette channels 202. The axis of the first cigarette channel 202 is vertically arranged, with its top end extending to the top surface of the cigarette distribution block 2 and its bottom end extending to the bottom surface of the cigarette distribution block 2.

[0033] In this embodiment, two sets of first cigarette channels 202 are provided. Each set of first cigarette channels 202 has two rows of first cigarette channels 202. Multiple first cigarette channels 202 in each row are arranged along the length direction of the cigarette distribution block 2. The two rows of first cigarette channels 202 in the same set are staggered.

[0034] The first cigarette channel 202 is used to receive cigarettes falling from the mold.

[0035] To facilitate the reception of cigarettes, the first cigarette channel 202 includes a first channel section and a second channel section arranged coaxially. The top end of the first channel section extends to the top surface of the cigarette distribution block 2, and the bottom end is connected to the top end of the second channel section. The bottom end of the second channel section extends to the bottom surface of the cigarette distribution block 2. The first channel section adopts an inverted conical structure, and the area of ​​its top end is larger than the area of ​​its bottom end. The second channel section adopts a cylindrical structure.

[0036] like Figure 5 As shown, the cigarette guide block 1 is provided with a plurality of second cigarette channels 101. The axis of the second cigarette channel 101 is arranged vertically. Each first cigarette channel 202 is provided with a corresponding second cigarette channel 101. The top end of the second cigarette channel 101 extends to the top surface of the cigarette guide block 1 and communicates with the bottom end of the first cigarette channel 202. The bottom end of the second cigarette channel 101 extends to the bottom surface of the cigarette guide block 1.

[0037] Since the first cigarette channel 202 is provided in two sets, the second cigarette channel 101 is also provided in two sets, with each set having two rows of second cigarette channels 101.

[0038] In order for the cigarette in the first cigarette channel 202 to fall smoothly into the second cigarette channel 101, the second cigarette channel 101 is coaxially arranged with the first cigarette channel 202, and the diameter of the second cigarette channel 202 is larger than the diameter of the first cigarette channel 101.

[0039] Each second cigarette channel 101 is connected to an air blowing channel 102 located in the cigarette guide block.

[0040] The axis of the air blowing channel 102 is set at a set acute angle with the axis of the second cigarette channel 101. One end of the air blowing channel 102 extends to the top surface of the cigarette guide block 1 as the air inlet side, and the other end is connected to the side of the second cigarette channel 101 as the air outlet side. The height of the air inlet side of the air blowing channel 102 is higher than the height of the air outlet side.

[0041] Multiple air blowing channels 102 are positioned between the two rows of second cigarette channels 101 in the same group.

[0042] The bottom end of the second cigarette channel 101 is connected to the top end of the guide tube 103. The guide tube 103 is vertically arranged and coaxial with the second cigarette channel 101. The top end of the guide tube 103 is inserted and fixed to the expansion section provided at the bottom end of the second cigarette channel 101. The inner diameter of the expansion section is larger than the inner diameter of the rest of the second cigarette channel 101. After the guide tube 103 is inserted into the expansion section, its inner surface is flush with the inner surface of the rest of the second cigarette channel 101.

[0043] The bottom surface of the cigarette gas distribution block 2 is provided with multiple air inlet grooves 203 as air inlet channels connected to the air blowing channel 102. In this embodiment, each air inlet groove 203 is connected to multiple air blowing channels 102, so that all air blowing channels 102 are connected to the corresponding air inlet groove 203. Each air inlet groove 203 is connected to an air inlet hole 201. The U-shaped air inlet grooves located at the two ends along the length direction of the cigarette gas distribution block 2 are connected to the air inlet holes opened at the ends along the length direction of the cigarette guide block 1. The bottom end of the air inlet hole opened in the cigarette guide block 1 extends to the bottom surface of the cigarette guide block 1, and the top end extends to the top surface of the cigarette guide block 1 and is connected to the air inlet groove 203. The remaining air inlet grooves 203 are connected to the air inlet holes 201 opened in the cigarette gas distribution block 2. One end of the air inlet hole 201 of the cigarette gas distribution block 2 extends to the side of the cigarette gas distribution block 2, and the other end is connected to the air inlet groove 203.

[0044] With this configuration, multiple air-blowing channels share a single air inlet slot, and each air inlet slot is equipped with a connected air inlet hole, reducing the number of air inlets required and lowering the overall manufacturing cost of the device.

[0045] The air inlet 201 is connected to an air source via an air pipe. Preferably, the air source is an air compressor that can provide gas at a set pressure.

[0046] The top end of the guide tube 103 is fixed to the cigarette guide block 1, and its bottom end is connected to one end of the bend tube. The other end of the bend tube is used to cooperate with the collection device.

[0047] In this embodiment, the bend is a 90° bend, used to change the cigarette from a vertical to a horizontal position. Preferably, the bend is a flexible tube, and the radius of the bend is not less than 1 meter.

[0048] Example 2

[0049] This embodiment provides a method for the pneumatic cigarette conveying device described in Embodiment 1. The first cigarette channel 202 of the cigarette distribution block 2 receives cigarettes in a vertical posture falling from the mold. After passing through the first cigarette channel 202, the cigarettes fall into the second cigarette channel 101. The cigarettes falling into the second cigarette channel 101 are subjected to the wind force of the air blowing channel 102. Under the action of the wind force, the cigarettes fall along the second cigarette channel 101 into the guide tube 103 and then into the bend tube. They travel in the bend tube and change from a vertical state to a horizontal state before entering the collection device.

[0050] The device in this embodiment delivers cigarettes under pneumatic action and changes from a vertical to a horizontal state under the action of the bending tube. Compared with electric tilting equipment, the pneumatic conveying method has a shorter conveying time and higher efficiency, thus improving the production efficiency of the cigarette production line.

[0051] Example 3

[0052] This embodiment provides a cigarette production line for granular heated non-combustible cigarettes, including the pneumatic cigarette conveying device described in Embodiment 1, wherein the cigarette gas distribution block 2 is located below the mold, and the outlet of the bent pipe cooperates with the collection device.

[0053] The remaining structure of the production line can be achieved using existing technology, and will not be described in detail here.

[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
