Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette production equipment, and specifically relates to a cigarette production device. Background Art

[0002] In the traditional cigarette production process, tobacco is generally rolled into double-length cigarette rods in the horizontal direction using cigarette paper, which are then cut into two single-length cigarette rods using a rotating blade. A double-length filter rod is then spliced ​​between the two cigarette rods to form a double-length cigarette, which is then cut into two single-length cigarette rods.

[0003] However, for heat-not-burn cigarettes, the tobacco material is generally a granular tobacco material, which is obtained by crushing the tobacco raw material, mixing the tobacco raw material with an atomizer, a binder, and flavors and spices, and then going through the steps of alcoholization, extrusion, and granulation. Different from the traditional cigarette production process, in the manufacturing process of granular cigarettes, a hollow cigarette is first made, and after the hollow end of the cigarette is facing upward, the granular tobacco material is filled into the hollow of the cigarette, and then the cigarette is glued and packaged. In order to improve the production efficiency of granular cigarettes, double-length cigarettes with hollow ends are generally made. After the hollow cigarette on the upper side is poured, glued and packaged, the double-length cigarette needs to be rotated 180° in the vertical plane to make the hollow cigarette on the other side face upward.

[0004] In the current cigarette production equipment, when turning around cigarettes, multiple steering structural components are generally used to turn and transfer cigarettes. The transfer structure is relatively complex, and the cigarette turning and transfer rate is low, resulting in low cigarette production efficiency. The steering structural components generally clamp and fix the cigarettes in a semicircular manner, and the clamping of the cigarettes is unstable. During the turning process, the cigarettes are easily dropped from the steering structural components, resulting in an increase in the scrap rate of cigarette processing. Moreover, during the turning process, the position of the cigarettes may shift, and the filling, gluing and packaging devices in the cigarette production line do not accurately position the cigarettes, which may easily cause the granular tobacco materials to be scattered and wasted, affecting the industrial production of cigarettes. Utility Model Content

The driving part cooperates with the mating parts for transmission so that the shaft body rotates intermittently.

[0020] The driving part includes a driving protrusion protruding radially along the first driving shaft, and the transmission shaft includes a shaft body and a transmission part. The shaft body is eccentrically arranged with the first driving shaft, and the transmission part is provided with a plurality of matching parts at intervals along its own circumference.

[0021] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0022] 1. In the utility model, cigarettes are accommodated in a receiving cavity, the extension direction of the receiving cavity is perpendicular to the horizontal rotation axis, and the turning piece can rotate around the rotation axis, so that the cigarette can make a 180° turn in a vertical rotation plane. During the processing of cigarettes, generally, double-length cigarettes with hollow ends are processed and produced. The cigarettes are placed in a vertical state. After the processing of the cigarettes with the hollow ends facing upwards is completed, the device can make a 180° turn in a vertical plane, and rotate the hollow cigarettes to be processed on the other side upwards for subsequent processing and production, thereby improving the degree of automation of cigarette production. The turning piece can be provided with a plurality of receiving cavities arranged in an axial direction, so as to synchronously turn multiple cigarettes at the same time, and synchronously process and produce multiple cigarettes at the same time, thereby improving the efficiency of cigarette production. The placement hole extends through the turning piece to form the accommodating cavity. After the cigarette is accommodated in the accommodating cavity, during the turning process, the cigarette is located in the accommodating cavity inside the turning piece and will not be squeezed by the external structure and deformed. The turning piece protects the cigarette, avoids deformation and damage of the cigarette, and improves the yield rate of the cigarette.

[0023] In addition, the negative pressure regulating component is connected to the accommodating chamber, and the negative pressure regulating component forms a negative pressure airflow between the inner wall of the accommodating chamber and the cigarette, and the negative pressure airflow forms an adsorption force between the inner wall of the accommodating chamber and the cigarette, so that the cigarette is adsorbed on the inner wall of the accommodating chamber. The negative pressure regulating component forms a restriction on the accommodating position of the cigarette in the accommodating chamber, so as to prevent the cigarette from falling out of the accommodating chamber when the turning member rotates around the horizontal rotation axis, thereby reducing the waste loss in the cigarette processing process. Moreover, after the position of the cigarette in the accommodating chamber is fixed, it is more convenient to combine with the filling mechanism of the smoke-generating medium in the cigarette production process, the gluing and packaging mechanism at the open end of the cigarette tube, and other processing equipment, so that the filling mechanism and the gluing and packaging mechanism can position and process the cigarette in the accommodating chamber, thereby improving the level of industrialized flow processing of cigarettes.

[0024] 2. As a preferred embodiment of the present invention, the interior of the accommodating chamber has a filling chamber surrounded by cigarettes, and an airflow chamber located between the cigarettes and the inner wall of the accommodating chamber. The negative pressure regulating component includes an air pump, which is connected to the airflow chamber, and the air pump can suck the airflow in the airflow chamber or blow airflow into the airflow chamber to make the air pressure in the airflow chamber lower than the air pressure in the filling chamber. The air pump can suck the airflow in the airflow chamber or blow airflow into the airflow chamber to accelerate the flow of air in the airflow chamber, thereby making the air pressure in the airflow chamber lower than the air pressure in the filling chamber, so that the cigarettes are adsorbed on the inner wall of the accommodating chamber to prevent the cigarettes from falling off.

[0025] On this basis, the air pressure in the airflow chamber is lower than the air pressure in the filling chamber. The empty tube of the cigarette expands outward under the push of the airflow in the filling chamber, so that the volume of the filling chamber increases, and the filling port surrounded by the cigarettes also increases, thereby making it easier for the filling mechanism of the smoke-generating medium in the cigarette production process to position the cigarettes, thereby improving the adaptability of the cigarette production device to the cigarette production line, and at the same time reducing the possibility of the filling mechanism filling the smoke-generating medium into the airflow chamber, thereby improving the accuracy of the smoke-generating medium filling and reducing the waste of the smoke-generating medium.

[0026] 3. As a preferred embodiment of the present invention, the negative pressure regulating component includes a connecting piece and a distributing piece, the connecting piece has an annular airway, the turning piece has an installation position, an unloading position and a transition position between the installation position and the unloading position, the turning piece can rotate relative to the distributing piece so that the cigarette rotates between the installation position, the transition position and the unloading position, the distributing piece is provided with a shielding portion capable of shielding a part of the annular airway and a distributing airway connected to a part of the annular airway, the distributing airway is at least connected to the installation position and the transition position. The accommodating cavity corresponding to the installation position extends in the vertical direction, and when a double-length hollow cigarette at both ends is vertically placed in the accommodating cavity corresponding to the installation position, the hollow cigarette at the upper end is filled, glued and packaged. After the turning piece rotates 180° along the horizontal rotation axis, the cigarette is rotated 180° in the vertical direction, the unprocessed hollow cigarette at the other end of the cigarette faces upward, and the hollow cigarette at the other end is filled, glued and packaged. When in the installation position and the unloading position, the cigarettes to be processed all have hollow ends facing upwards, and the processing is performed on the hollow cigarettes facing upwards, which is convenient for filling, gluing and packaging processing operations, and is convenient for the design of the processing line. When the smoking medium is filled into the hollow cigarettes facing upwards, the smoking medium is poured into the hollow of the cigarettes under the action of gravity, which reduces the spillage of the smoking medium and makes the smoking medium more evenly and tightly distributed in the hollow of the cigarettes.

[0027] When the turning piece rotates between the installation position, the unloading position and the transition position, the accommodating chamber may be in a vertical state or an inclined state, and the cigarette may slip or deflect in the accommodating chamber, affecting the processing of the cigarette or reducing the yield of the processed cigarette. The distribution air duct is at least connected to the installation position and the transition position, and a negative pressure airflow is formed between the inner wall of the accommodating chamber corresponding to the installation position and the transition position and the cigarette, so as to adsorb the cigarette to the inner wall of the accommodating chamber and reduce the problem of the cigarette slipping or deflecting. When the distribution air duct is connected to the unloading position, it also plays a role in reducing the problem of the cigarette slipping or deflecting.

[0028] 4. As a preferred embodiment of the present invention, there are four mounting bosses and they are evenly distributed along the circumference of the turning piece.

The second driving shaft is eccentrically arranged with the first driving shaft, and the second driving shaft rotates around the first driving shaft. During the rotation of the second driving shaft, the second driving shaft is intermittently in contact with the matching parts, thereby driving the transmission shaft to rotate intermittently.

[0050] like Figures 1 to 3 As shown, a cigarette production device includes: a head-adjusting member 2, which can rotate around a horizontal rotation axis 21, and the head-adjusting member 2 is provided with at least one placement hole 22, and the placement hole 22 extends through the head-adjusting member 2 to form a receiving chamber 23 for receiving the cigarette 1, and the extension direction of the receiving chamber 23 is perpendicular to the rotation axis 21; a negative pressure regulating component 3, the negative pressure regulating component 3 is connected to the receiving chamber 23, and can form a negative pressure airflow between the inner wall of the receiving chamber 23 and the cigarette 1, so that the cigarette 1 is adsorbed on the inner wall of the receiving chamber 23.

[0051] The cigarette 1 is accommodated in the accommodating cavity 23, and the extension direction of the accommodating cavity 23 is perpendicular to the horizontal rotation axis 21. The turning piece 2 can rotate around the rotation axis 21, so that the cigarette 1 can turn around 180° in the vertical rotation plane. During the processing of the cigarette 1, generally, the cigarettes with double length and hollow ends are processed and produced. The cigarettes are placed in a vertical state. After the processing of the cigarettes 1 with the hollow ends facing upwards is completed, the device can turn the cigarettes around 180° in the vertical plane, and rotate the hollow cigarettes to be processed on the other side upwards for subsequent processing and production, thereby improving the degree of automation of the production of the cigarettes 1. The turning piece 2 can arrange multiple accommodating cavities 23 along the axial direction, so as to synchronously turn multiple cigarettes 1 at the same time, and synchronously process and produce multiple cigarettes 1 at the same time, thereby improving the efficiency of the production of cigarettes 1. The placement hole 22 extends through the turning piece 2 to form the accommodating cavity 23. After the cigarette 1 is accommodated in the accommodating cavity 23, during the turning process, the cigarette 1 is located in the accommodating cavity 23 inside the turning piece 2 and will not be squeezed and deformed by the external structure. The turning piece 2 protects the cigarette 1, avoids deformation and damage of the cigarette 1, and improves the yield rate of the cigarette 1.

[0052] It should be noted that the cigarette production device in the utility model is suitable for the processing and production of granular cigarettes. The granular cigarette is a heat-not-burn tobacco product. The granular tobacco material can be obtained by crushing the tobacco raw material, mixing the tobacco raw material with an atomizer, a binder, and flavors and spices, and then through the steps of alcoholization, extrusion, and granulation. In the manufacturing process of the granular cigarette, a hollow cigarette is generally made first, and after the hollow end of the cigarette is facing upward, the granular tobacco material is filled into the hollow of the cigarette, and then the cigarette is glued and packaged.

[0053] It should be noted that the cigarette production device in the utility model can vertically load double-length hollow cigarettes at both ends, and after the cigarette 1 is adsorbed in the accommodating cavity 23, the hollow cigarettes facing upward can be filled, glued and packaged. Similarly, after the hollow cigarettes facing upward are filled, glued and packaged, they can be transported to the cigarette production device for orientation adjustment, so that the hollow cigarettes on the other side that are not filled with granular tobacco materials face upward, and the cigarette production device plays a role in turning the cigarettes 1 inward in the vertical direction.

[0054] The negative pressure regulating component 3 is connected to the accommodating chamber 23, and the negative pressure regulating component 3 forms a negative pressure airflow between the inner wall of the accommodating chamber 23 and the cigarette 1, and the negative pressure airflow forms an adsorption force between the inner wall of the accommodating chamber 23 and the cigarette 1, so that the cigarette 1 is adsorbed on the inner wall of the accommodating chamber 23. The negative pressure regulating component 3 forms a restriction on the accommodating position of the cigarette 1 in the accommodating chamber 23, so as to prevent the cigarette 1 from falling out of the accommodating chamber 23 when the turning member 2 rotates around the horizontal rotation axis 21, thereby reducing the waste loss in the processing of the cigarette 1. In addition, after the position of the cigarette 1 in the accommodating chamber 23 is fixed, it is more convenient to combine with the filling mechanism of the smoking medium in the cigarette production process, the glue coating and packaging mechanism at the open end of the cigarette tube, and other processing equipment, so that the filling mechanism and the glue coating and packaging mechanism can position and process the cigarette 1 in the accommodating chamber 23, thereby improving the level of industrialized flow processing of cigarettes.

[0055] It should be noted that the negative pressure airflow in the present invention refers to the accelerated airflow formed between the cigarette 1 and the side wall of the accommodating chamber 23. The negative pressure airflow makes the air pressure in the space between the cigarette 1 and the side wall of the accommodating chamber lower than the air pressure inside the cigarette 1.

[0056] As a preferred embodiment of the present invention, Figure 3 and Figure 4As shown, the accommodating chamber 23 has a filling chamber 231 surrounded by cigarettes 1, and an airflow chamber 232 located between the cigarettes 1 and the inner wall of the accommodating chamber 23. The negative pressure regulating component 3 includes an air pump, which is connected to the airflow chamber 232 and can suck the airflow in the airflow chamber 232 or blow airflow into the airflow chamber 232, so that the air pressure in the airflow chamber 232 is lower than the air pressure in the filling chamber 231.

[0057] The utility model does not limit the type of the air pump. The air pump can suck the air in the airflow chamber 232 or blow the air into the airflow chamber 232. One of the following embodiments can be used.

[0058] Embodiment 1: The air pump is a blowing pump, which is connected to the airflow chamber 232 to blow airflow into the airflow chamber 232, thereby accelerating the flow speed of the airflow in the airflow chamber 232, so that the air pressure in the airflow chamber 232 is lower than the air pressure in the filling chamber 231, so that the cigarette 1 is adsorbed on the inner wall of the accommodating chamber 23 to prevent the cigarette 1 from falling off.

[0059] Embodiment 2: The air pump is an air suction pump, which is connected to the airflow chamber 232 and can draw air from the airflow chamber 232, thereby reducing the air pressure in the airflow chamber 232, so that the air pressure in the airflow chamber 232 is lower than the air pressure in the filling chamber 231, so that the cigarette 1 is adsorbed on the inner wall of the accommodating chamber 23, thereby preventing the cigarette 1 from falling off.

[0060] On this basis, the air pressure in the airflow chamber 232 is lower than the air pressure in the filling chamber 231. The empty tube of the cigarette 1 expands outward under the impetus of the airflow in the filling chamber 231, so that the volume of the filling chamber 231 increases, and the filling port surrounded by the cigarettes also increases, thereby making it easier for the filling mechanism of the smoking medium in the cigarette production process to position the cigarette 1, thereby improving the adaptability of the cigarette production device to the cigarette production line, and at the same time reducing the possibility of the filling mechanism filling the smoking medium into the airflow chamber 232, thereby improving the accuracy of the smoking medium infusion and reducing the waste of the smoking medium.

[0061] Preferably, Figure 1 , Figure 2 and Figure 7As shown, the accommodating chamber 23 is provided with a plurality of negative pressure air holes 24 along its own axial direction, and the negative pressure regulating component 3 is connected with the negative pressure air holes 24 to form a negative pressure airflow between the inner wall of the accommodating chamber 23 and the cigarette 1. The negative pressure airflow generated by the negative pressure regulating component 3 flows to the accommodating chamber 23, flows along the inner wall of the accommodating chamber 23 and between the cigarette 1, and communicates with the outside through the negative pressure air holes 24. The accommodating chamber 23 is provided with a plurality of negative pressure air holes 24 along its own axial direction, which improves the uniformity of the distribution of the negative pressure airflow in the accommodating chamber 23, so that the cigarette 1 is uniformly adsorbed on the inner wall of the accommodating chamber 23. The negative pressure air holes 24 can avoid the problem of excessive local force on the cigarette 1 causing the cigarette 1 to deform, and can also avoid the problem of the cigarette 1 tilting in the accommodating chamber 23, so that the cigarette 1 can be in a vertical state, so as to facilitate the coordination of the processing steps such as filling, gluing and packaging of the cigarette 1 in the cigarette production process.

[0062] Preferably, Figure 2 , Figure 5 and Figure 6 As shown, the negative pressure regulating assembly 3 includes a connecting member 31 and a distributing member 32, the connecting member 31 has an annular airway 311, the turning member 2 has an installation position 251, an unloading position 253 and a transition position 252 located between the installation position 251 and the unloading position 253, the turning member 2 can rotate relative to the distributing member 32 so that the cigarette 1 can rotate between the installation position 251, the transition position 252 and the unloading position 253, the distributing member 32 is provided with a shielding portion 321 capable of shielding a part of the annular airway 311 and a distributing airway 322 connected with a part of the annular airway 311, the distributing airway 322 is at least connected with the installation position 251 and the transition position 252. The accommodating cavity 23 corresponding to the installation position 251 extends in the vertical direction, and when a double-length cigarette with hollow ends is vertically placed in the accommodating cavity 23 corresponding to the installation position 251, the hollow cigarette at the upper end is filled, glued and packaged. After the turning member 2 rotates 180° along the horizontal rotation axis 21, the cigarette 1 rotates 180° in the vertical direction, and the unprocessed hollow cigarette at the other end of the cigarette 1 faces upward, and the filling, gluing and packaging processing of the hollow cigarette at the other end is carried out. When in the installation position 251 and the unloading position 253, the cigarettes 1 to be processed all have hollow ends facing upward, and the hollow cigarettes facing upward are processed, which is convenient for the filling, gluing and packaging processing operations and the design of the processing line. When the hollow cigarette facing upward is filled with the smoking medium, the smoking medium is poured into the hollow of the cigarette under the action of gravity, which reduces the spillage of the smoking medium and makes the smoking medium more evenly and tightly distributed in the hollow of the cigarette.

[0063] When the turning member 2 rotates between the mounting position 251, the unloading position 253 and the transition position 252, the accommodating chamber 23 may be in a vertical state or an inclined state, and the cigarette 1 may slide or deflect in the accommodating chamber 23, affecting the processing of the cigarette 1, or reducing the yield rate of the processed cigarette 1. The distribution air channel 322 is at least connected to the mounting position 251 and the transition position 252, and a negative pressure airflow is formed between the inner wall of the accommodating chamber 23 corresponding to the mounting position 251 and the transition position 252 and the cigarette 1, so as to adsorb the cigarette 1 to the inner wall of the accommodating chamber 23, thereby reducing the problem of the cigarette 1 sliding or deflecting.

[0064] The distribution air channel 322 is in communication with at least a portion of the unloading position 253. Figure 2 As shown, when the distribution air channel 322 is fully connected with the unloading position 253, the negative pressure regulating component 3 generates a negative pressure airflow in the accommodating chamber 23 corresponding to the unloading position 253, stably adsorbs the cigarette 1 in the accommodating chamber 23, prevents the cigarette from falling off at will, and also facilitates the processing of the hollow cigarette facing upward corresponding to the unloading position 253.

[0065] In another embodiment, the distribution air channel 322 is connected to a partial area of ​​the unloading position 253, which can reduce the negative pressure airflow generated by the air pump in the accommodating chamber 23 corresponding to the unloading position 253, and reduce the adsorption force between the cigarette 1 and the inner wall of the accommodating chamber 23, thereby facilitating the removal of the cigarette 1 from the accommodating chamber 23.

[0066] Specifically, Figure 2 , Figure 6 and Figure 7As shown, the reversing member 2 also has a second transition position 254 that rotates from the unloading position 253 to the mounting position 251. The cigarette 1 placed in the accommodating cavity 23 moves along the path of the mounting position 251-transition position 252-unloading position 253 as the reversing member 2 rotates. The cigarette 1 is loaded into the accommodating cavity 23 at the mounting position 251 and is taken out of the accommodating cavity 23 at the unloading position 253. The accommodating cavity 23 corresponding to the second transition position 254 does not contain a cigarette 1. The circumferential extension angles of the mounting position 251, the transition position 252, the unloading position 253, and the second transition position 254 are all 90°. The distribution member 32 has a distribution airway 322 that extends 270° in the circumferential direction. The distribution member 32 is circumferentially adjustable on the connecting member 31.
