Description

[0002] The nicotine bag is an innovative product to replace tobacco, which is different from traditional tobacco products. The nicotine bag does not need to be burned or heated, and does not produce smoke, and has the characteristics of environmental friendliness.

[0003] At present, the nicotine bag is mostly manufactured by using traditional smoke-containing packaging equipment, and the loading mechanism is used to load materials into the non-woven bag. In the early stage, because the nicotine bag is mostly manufactured by using dry process, the equipment can basically meet the production requirements, but the dry process is easy to damage the oral mucosa, so that the wet process gradually occupies the mainstream market. However, the wet process involves high-humidity tobacco powder (for example, more than 40% water content), and the applicability of the traditional smoke-containing packaging equipment is poor. The high-humidity tobacco powder is easy to stick and accumulate, and the pipe is easy to be blocked in the loading mechanism of the smoke-containing packaging equipment, which leads to frequent whole-line shutdown and debugging, and affects the production process.

DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0044] The core of the present application is to provide a feeding mechanism and a packaging machine comprising the feeding mechanism, which has good applicability and can ensure the packaging efficiency of materials with various humidities.

[0045] A specific embodiment of the charging mechanism provided by the present application is described below with reference to Figures 3 to 8 , which comprises a feeding device 1 including a feeding container 14, a material distribution assembly 2, a discharging pipe 11 and a stirring roller.

[0046] The material distribution assembly 2 comprises a material distribution driver and a material distribution body 22 connected to the material distribution driver. The top of the material distribution body 22 extends into the feeding container 14 and can serve as the inner bottom surface of the feeding container 14 to receive the material entering the feeding container 14.

[0047] A plurality of material grooves 221 are arranged on the top surface of the material distribution body 22 in sequence around the rotation axis of the material distribution body 22. Each material groove 221 can move to a preset discharging position in sequence. The inlet end of the discharging pipe 11 is arranged above the preset discharging position. The material in each material groove 221 can pass through the preset discharging position and be discharged to the bag through the discharging pipe 11. The material can be tobacco powder or other powder or small granular material. The bag can be a non-woven fabric formed packaging bag, which can be a nicotine bag or a plastic bag for other fields.

[0048] The stirring roller is rotatable and extends into the feeding container 14. The rotation of the stirring roller can disperse the material.

[0049] In the above charging mechanism, after the feeding container 14 is replenished, for example, at a position close to the stirring roller, the material falls onto the top surface of the material distribution body 22 and is stirred when passing through the stirring roller to disperse the material. In particular, when the material is high-humidity material, such as high-humidity tobacco powder, the stirring roller can stir the adhered material and spread it evenly on different positions on the top surface of the material distribution body 22 to enter different material grooves 221. This can prevent the material from adhering and accumulating to a height that exceeds the feeding container 14 and can prevent the material from being blocked in the discharging pipe 11 due to adhesion. This can ensure the smooth charging of high-humidity nicotine bags and achieve high-speed and stable packaging of high-humidity tobacco powder (water content above 40%) while being compatible with dry tobacco powder and traditional chewing tobacco, which has good applicability and can improve packaging efficiency.

[0050] In some embodiments, to realize the feeding of the material grooves 221 to the discharging pipe 11, compressed air can be introduced into the bottom of the material grooves 221 through an air passage to feed the discharging pipe 11; or a spiral conveying component or other equipment can also be added for feeding.

[0051] In some embodiments, to further improve the blocking problem of high-humidity tobacco powder in the discharging pipe 11, for example, Figure 6As shown, the auxiliary pressurizing port 111 is arranged on the middle part of the downcomer 11, and one auxiliary pressurizing port 111 is arranged in an embodiment. In other embodiments, a plurality of auxiliary pressurizing ports 111 can be arranged.

[0052] As shown in the drawings, Figure 6 As shown, the auxiliary pressurizing port 111 is arranged on the middle part of the downcomer 11, and one auxiliary pressurizing port 111 is arranged in an embodiment. In other embodiments, a plurality of auxiliary pressurizing ports 111 can be arranged.

[0053] As shown in the drawings, Figure 6 As shown, the auxiliary pressurizing port 111 is arranged on the middle part of the downcomer 11, and one auxiliary pressurizing port 111 is arranged in an embodiment. In other embodiments, a plurality of auxiliary pressurizing ports 111 can be arranged.

[0054] As shown in the drawings, Figure 6 As shown, the auxiliary pressurizing port 111 is arranged on the middle part of the downcomer 11, and one auxiliary pressurizing port 111 is arranged in an embodiment. In other embodiments, a plurality of auxiliary pressurizing ports 111 can be arranged.

[0055] As shown in the drawings, Figure 6 As shown, the auxiliary pressurizing port 111 is arranged on the middle part of the downcomer 11, and one auxiliary pressurizing port 111 is arranged in an embodiment. In other embodiments, a plurality of auxiliary pressurizing ports 111 can be arranged.

[0056] In some embodiments, the stirring roller can include a driving stirring roller 12 and a passive stirring roller 18. The driving stirring roller 12 can be driven by a driving member and can actively rotate to actively stir the material. The passive stirring roller 18 can be driven to rotate by the material and can also stir the material.

[0057] To achieve the rotation of the active stirring roller 12, such as Figure 4 and Figure 5 As shown, the feeding device 1 also includes a roller drive assembly 13 for driving the active stirring roller 12 to rotate. The roller drive assembly 13 is connected to the material distribution driver, which avoids the need for an additional power source and helps reduce costs. Of course, in other embodiments, the active stirring roller 12 and the material distribution body 22 can also be driven by separate drivers, such as by separate motors.

[0058] For example, such as Figure 4 and Figure 5 As shown, the roller drive assembly 13 includes an elastic element 131, a passive roller 132, and an intermediate drive element 133. The elastic element 131 is connected to the passive roller 132 so that the passive roller 132 is pressed against the material distribution body 22 and driven to rotate by the friction between the passive roller 132 and the material distribution body 22. The passive roller 132 is connected to the active stirring roller 12 through the intermediate drive element 133.

[0059] At this time, when the material distribution body 22 rotates under the drive of the material distribution driver, the elastic element 131 presses the passive roller 132 against the material distribution body 22, and there is friction between the material distribution body 22 and the passive roller 132. The passive roller 132 can rotate under the drive of friction, and then the passive roller 132 drives the active stirring roller 12 to rotate through the intermediate transmission element 133.

[0060] For example, the elastic element 131 is a tension spring. Specifically, the passive roller 132 is rotatably connected to the first roller shaft, which is slidably disposed on the mounting platform. One end of the elastic element 131 is connected to the first roller shaft, and the other end is connected to the mounting platform. Under the pull of the elastic element 131, the first roller shaft is brought closer to the material distribution body 22, ensuring that the passive roller 132 presses against the material distribution body 22, mainly pressing against the portion of the material distribution body 22 located below the feed container 14.

[0061] For example, the intermediate transmission member 133 is a belt transmission member; in other embodiments, it can also be a gear transmission assembly. Figure 4 and Figure 5 As shown, the belt drive includes a first synchronous belt assembly 1331 and a second synchronous belt assembly 1332 connected above the first synchronous belt assembly 1331. The first synchronous belt assembly 1331 is connected to the first roller shaft of the passive roller 132, and the second synchronous belt assembly 1332 is connected to the intermediate shaft of the active stirring roller 12. The belt drive provides good stability.

[0062] In addition, to achieve the rotation of the passive stirring roller 18, such as Figure 5 As shown, the feeding device 1 also includes a top plate 17 fixedly connected to the feeding container 14, and the top of the passive stirring roller 18 is rotatably connected to the top plate 17.

[0063] In addition, to further prevent material from accumulating above the material distribution body 22 in the feed container 14, such as Figures 3 to 5 As shown, along the rotation direction of the material distribution body 22, a guide plate 16 and a passive stirring roller 18 are arranged between the feeding side of the active stirring roller 12 and the feeding side of the preset feeding position. The guide plate 16 can be fixedly connected to the top plate 17, or the inner side of the feeding container 14, or fixedly connected to the cover plate below the top plate 17. The material can move with the material distribution body 22 around the cover plate. Multiple guide plates 16 and passive stirring rollers 18 can be provided and can be arranged in a cross pattern.

[0064] When the material distribution body 22 rotates, the material passes through the active stirring roller 12, then through the guide plate 16 and the passive stirring roller 18 to reach the preset discharge position. During this process, the guide plate 16 can sort the material on the material distribution body 22, guide the material flow, and avoid material blockage. The passive stirring roller 18 can rotate under the drive of the material to realize non-powered stirring of the material, and further effectively disperse the sticky smoke powder.

[0065] In addition, the guide plate 16 can be slidably connected to the feed container 14 or the cover plate so as to fit the top surface of the dispensing body 22 when the dispensing body 22 is raised or lowered; or, the bottom end of the guide plate 16 can be an elastic part or a flexible part so as to maintain a fit to the top surface of the dispensing body 22 when the dispensing body 22 is raised or lowered.

[0066] In some embodiments, in order to achieve online adjustment of the filling amount of each bag in the dispensing body 22, the anti-clogging filling design and the material tank volume adjustment design in the filling mechanism can adapt to dry, semi-dry and semi-wet and wet tobacco powder (humidity 0-50%), which not only solves the problem of high humidity tobacco powder, but is also backward compatible with traditional oral tobacco, making it more adaptable to the market.

[0067] like Figure 6 and Figure 7 As shown, the material distribution body 22 includes a venting disc 222 and an indexing disc 223 that can rotate synchronously.

[0068] Specifically, the venting disc 222 is located below the feed container 14, and the indexing disc 223 is vertically connected above the venting disc 222 and is located inside the feed container 14. The top edge of the indexing disc 223 fits against the inner circumferential surface of the feed container 14 to receive the material entering the feed container 14. The driven roller 132 presses against the venting disc 222 and is driven by rolling friction between itself and the venting disc 222.

[0069] The indexing disc 223 is provided with a plurality of distribution holes 2231 around the rotation axis of the distribution main body 22, the ventilation disc 222 is provided with ventilation holes 2221 corresponding to the distribution holes 2231 respectively, each ventilation hole 2221 is fixedly connected with a ventilation column 224, the top end of each ventilation column 224 is slidably inserted into the corresponding distribution hole 2231, the top of the ventilation column 224 is fixed with a mesh tray 225, and the space in the distribution hole 2231 above the mesh tray 225 forms a material groove 221.

[0070] It should be noted that the different ventilation holes 2221 are respectively formed on the ventilation disc 222 and are not communicated, each material groove 221 is also respectively located on the indexing disc 223 and is not communicated, the ventilation holes 2221 correspond to the material grooves 221 one by one, and are communicated one by one through the separate ventilation columns 224, so that each material groove 221 can be sequentially discharged at a preset discharge position. For example, 16 material grooves 221 are arranged around the rotation axis of the distribution main body 22, and correspondingly, the distribution holes 2231, the ventilation columns 224 and the ventilation holes 2221 are also 16. The material grooves 221 can be uniformly arranged circumferentially, so that the distribution main body 22 moves by the same angle each time, and switches one material groove 221 moving to the preset discharge position.

[0071] In addition, the mesh holes on the mesh tray 225 can be ventilated upward to push the material in the material groove 221 upward, but generally should be smaller than the size of a single material to avoid the material falling downward to the mesh tray 225.

[0072] When it is necessary to adjust the volume of the material groove 221 to realize the adjustment of the filling amount, the indexing disc 223 moves up and down, the ventilation column 224 and the mesh tray 225 fixed on the ventilation disc 222 remain unchanged in height, the height difference between the top of the distribution hole 2231 and the mesh tray 225 changes, and the volume of the material groove 221 formed thereby changes, thereby achieving the purpose of adjusting the filling amount, and adapting to the requirements of different humidity tobacco powder and improving the packaging precision.

[0073] When discharging, one material groove 221 moves to below the inlet of the discharge pipe 11, specifically, the inlet of the discharge pipe 11 or the bottom end of the discharge distribution cylinder 114 can be slidably inserted into the top of the distribution hole 2231 and sealingly fit, as shown in Figure 6 The corresponding ventilation hole 2221 of the material groove 221 is connected with the air blowing device 24, compressed air enters the ventilation hole 2221 from the air blowing device 24, the tobacco powder in the material groove 221 is blown upward through the mesh holes of the ventilation column 224 and the mesh tray 225, enters the small bag through the discharge pipe 11, and the material filling is completed.

[0074] Exemplarily, the indexing disc 223 is connected with the filling amount adjustment driving device to realize lifting. As shown in Figure 6As shown, the filling amount adjustment driving device comprises a filling amount adjustment motor 23 and a filling amount adjustment swing arm 21. When it is necessary to adjust the volume of the material tank 221 to achieve filling amount adjustment, the filling amount adjustment motor 23 drives the filling amount adjustment swing arm 21 to swing to drive the index plate 223 to move up and down, achieving online adjustable filling amount.

[0075] Specifically, the first lifting shaft is supported below the index plate 223, the first lifting shaft is connected to one end of the filling amount adjustment swing arm 21, the other end of the filling amount adjustment swing arm 21 is connected to the filling amount adjustment motor 23, and the filling amount adjustment swing arm 21 is rotationally connected to the fulcrum at the center, thereby forming a lever structure. The first lifting shaft is lifted by the filling amount adjustment swing arm 21 swinging around the fulcrum, and in turn drives the index plate 223 to rise and fall with the first lifting shaft.

[0076] In addition, to avoid interference with the rotation of the index plate 223 and the breather plate 222, the breather plate 222 is connected to the material distribution driver at the center below, the first lifting shaft can support the index plate 223 through the central passage of the material distribution driver and the central hole of the breather plate 222, the first lifting shaft is in contact with but not connected to the index plate 223, so that the index plate 223 can rise and fall with the first lifting shaft and can rotate relative to the first lifting shaft, and the first lifting shaft can be bearing connected with the material distribution driver and the breather plate 222. At this time, the material distribution driver drives the breather plate 222 to rotate, and the breather column 224 between the breather plate 222 and the index plate 223 drives the index plate 223 to rotate synchronously.

[0077] For the convenience of replenishing the feed container 14, as shown in Figure 3 and Figure 8 As shown, the charging mechanism further comprises a replenishing device 3. The replenishing device 3 comprises an oscillator 31 and a spiral oscillation lifting plate 32 connected to the oscillator 31. The spiral oscillation lifting plate 32 comprises spiral blades, and the spiral oscillation lifting plate 32 can smoothly lift the tobacco powder along the spiral blades from a low position to a high position through high-frequency micro-oscillation. The oscillator 31 is provided with an oscillation recovery tank 33 for charging above the oscillator 31, the spiral oscillation lifting plate 32 is located in the oscillation recovery tank 33, the oscillation recovery tank 33 is provided with a feed inlet 331, and the top of the spiral oscillation lifting plate 32 is provided with a replenishing port 321. The replenishing port 321 is connected to the top opening of the feed container 14 through a replenishing slide 34.

[0078] During the replenishing process, the tobacco powder is poured into the oscillation recovery tank 33 through the feed inlet 331 of the lower oscillation recovery tank 33, the oscillator 31 drives the spiral oscillation lifting plate 32 to generate high-frequency micro-oscillation, so that the tobacco powder is slowly lifted and transported upwards along the spiral blades on the spiral oscillation lifting plate 32 from the oscillation recovery tank 33, until it enters the replenishing slide 34 through the replenishing port 321 and then enters the feed container 14. During the oscillation and transportation process, the excess tobacco powder will fall back to the oscillation recovery tank 33 from the spiral blades.

[0079] The feeding device only needs to pour the material to the low position of the feeding device, and the tobacco powder is automatically supplied from the bottom to the top through high-frequency micro-vibration, so that the material is transported and fed from the low position to the high position, the overflow of the tobacco powder and manual intervention are avoided, the manual feeding operation on the high position is avoided, the working environment is improved, and for high-humidity materials, the vibration design can enhance the fluidity of the high-humidity materials, and the feeding efficiency and safe operation efficiency are greatly improved.

[0080] Alternatively, in other embodiments, the spiral vibration lifting disc 32 can also be replaced by a synchronous belt or a chain to realize the up-down lifting motion to the material disc, and then the material is vibrated into the feeding container 14 through horizontal vibration.

[0081] In some embodiments, as shown in Figure 3 To realize automatic control of the operation of the feeding device 3, the feeding device 1 further comprises a material level sensor 15, and the start-stop of the feeding device 3 can be controlled in a closed loop through the linkage of the material level sensor 15.

[0082] When the material level in the feeding container 14 detected by the material level sensor 15 is lower than the preset low material level, the tobacco powder in the feeding container 14 is insufficient, the vibrator 31 is automatically started, and the feeding device 3 will supplement the tobacco powder into the feeding container 14, so that the automatic low-position feeding of the tobacco powder in the feeding container 14 can be realized; when the material level in the feeding container 14 detected by the material level sensor 15 reaches the preset high material level, the vibrator 31 is automatically stopped, the feeding is in place, and the feeding device 3 stops vibrating and feeding. With the closed-loop control of the material level sensor 15 and the feeding device 3, unattended operation can be realized, and the sustainability of the working environment can be improved.

[0083] The feeding container 14 can be a transparent container, and the material level sensor 15 can be externally provided on the feeding container 14. Alternatively, the material level sensor 15 can also be internally provided in the feeding container 14.

[0084] In some embodiments, as shown in Figure 3 The feeding device 3 further comprises a closed shell 35, specifically a closed circular organic glass shell, which covers the spiral vibration lifting disc 32, can prevent the overflow of the tobacco powder and the contact of the human body, improve the cleanliness of the working environment, and reduce the accident rate.

[0085] In addition to the above feeding mechanism, the application also provides a packaging machine, specifically a high-speed nicotine bag packaging machine. The packaging machine comprises a feeding mechanism, which can be any of the above embodiments, and the beneficial effects can be correspondingly referred to the above embodiments.

[0086] In the specific embodiment one of the packaging machine provided by the application, please refer to Figures 1 to 15, which comprises a loading mechanism, a film roll feeding mechanism 4, a longitudinal sealing mechanism 5 and a transverse sealing mechanism 6.

[0087] The film roll feeding mechanism 4 is used to deliver the cylindrical film to the bottom end outlet of the downpipe 11, that is, to bend the planar film into a cylindrical shape. The film is specifically a non-woven fabric. The longitudinal sealing mechanism 5 is used to seal the two side edges of the cylindrical film to form a first cylinder, at this time, the longitudinal sealing edge a in Figure 12 is formed. The transverse sealing mechanism 6 is used to seal the bottom port of the first cylinder to form a second cylinder, at this time, the transverse sealing edge c in Figure 12 is formed, and is used to seal the top port of the second cylinder after the second cylinder is filled with material to form a packaging bag, at this time, the transverse sealing edge b in Figure 12 is formed, and the packaging is completed. The downpipe 11 is used to fill the second cylinder with material.

[0088] It should be noted that the cylindrical film, the first cylinder and the second cylinder are used to distinguish the different intermediate states of the film during the production process.

[0089] At this time, the loading mechanism, the film roll feeding mechanism 4, the longitudinal sealing mechanism 5 and the transverse sealing mechanism 6 cooperate in sequence, and the entire process of gradually processing the film into a bag body and sealing the opening of the bag body after loading can be completed. The continuous feeding and sealing and cutting are integrated, which can break through the traditional intermittent limitation, realize high-speed continuous production, improve the packaging speed, and reduce the waste of packaging materials.

[0090] In some embodiments, the film roll feeding mechanism 4 comprises a first film roll holder 41, a second film roll holder 42, a film driver 43, a film end positioning platform 44, a film butt joint device 45, a position limiter 49 and a cylinder former 46. The cylinder former 46 is specifically a collar former.

[0091] The film is wound on the first film roll holder 41 or the second film roll holder 42 in the form of a film roll, and the feeding can be continuously supplied by rotating the corresponding film roll holder. During operation, as shown in Figure 10 , the film driver 43 pulls the film roll on the first film roll holder 41 or the second film roll holder 42 to move along the first path (such as the solid line path shown in Figure 10 ), sequentially passes through the position limiter 49 and the cylinder former 46 to form a cylindrical film, and the film driver 43 always maintains a state of continuous traction output, so that the cylindrical film can be sequentially sealed longitudinally, sealed transversely, filled with material, and sealed transversely to complete the packaging.

[0092] For the roll film frame, since in the existing common film roll feeding mechanism, the non-woven fabric film roll is arranged on the roll film support, conveyed along the set path, when a roll of film roll is used up, it is necessary to manually take out the used film roll remaining structure from the roll film frame, replace the new film roll, and then re-thread into the roll film support. The replacement process usually takes 5-10 minutes. If the production capacity is 300 bags per minute, one replacement of the film roll will waste 1500-3000 bags of production capacity. After replacement, it is necessary to re-shape and make bags, which also wastes a certain amount of packaging materials and tobacco powder. In the embodiment, through the first roll film frame 41 and the second roll film frame 42, and the additional film end positioning platform 44 and the film butt joint device 45, the non-woven fabric film roll on one roll film frame can be replaced without stopping during the use-up process.

[0093] Specifically, as shown in Figure 9 and Figure 10 , the film roll on the first roll film frame 41 can move along the first path under the drive of the film driver 43, and the film butt joint device 45 is located on the side of the first position on the first path. The head end of the film roll on the second roll film frame 42 extends into the film butt joint device 45 and is fixed by the film end positioning platform 44.

[0094] When the end of the film roll on the first roll film frame 41 passes through the film butt joint device 45, the film end positioning platform 44 releases the film roll of the second roll film frame 42, and the film butt joint device 45 fixes the head end of the film roll of the second roll film frame 42 and the end of the film roll of the first roll film frame 41.

[0095] At this time, the film roll on the first roll film frame 41 is used first, and the film roll on the second roll film frame 42 is standby. When the film roll on the first roll film frame 41 passes through the film butt joint device 45, the head end of the film roll on the second roll film frame 42 is positioned in the film butt joint device 45 by the film end positioning platform 44, and the head end of the film roll on the second roll film frame 42 can be partially aligned with the moving film roll on the first roll film frame 41. When the film roll on the first roll film frame 41 is almost used up, the film butt joint device 45 acts to fix the head end of the film roll on the second roll film frame 42 and the film roll of the first roll film frame 41, and the film end positioning platform 44 releases the head end of the film roll on the second roll film frame 42. The new and old film rolls are connected as a whole, and the film roll on the second roll film frame 42 can be directly continued to be used, improving the operation efficiency.

[0096] Exemplarily, the film end positioning platform 44 can be positioned by negative pressure adsorption, and the roll film can also be pressed on the film end positioning platform 44 by movable clamping jaws or pressing blocks. In addition, a limiting mechanism such as a clamping groove is arranged on the film end positioning platform 44 to limit the shape of the film material.

[0097] Exemplarily, the film abutting device 45 is a heat-seal bonding mechanism, specifically comprising two film heat-seal heads arranged on both sides of the first position, which can be symmetrically pressed to heat-seal and bond the two film rolls together, and after heat-sealing, the old film roll drags the new film roll to continuously feed the film. Alternatively, the heat-seal bonding mechanism can also be replaced by an ultrasonic welding mechanism. In other devices using heat-sealing technology, the ultrasonic welding mechanism can also be replaced.

[0098] In some embodiments, in order to further improve the smoothness of the abutting of the two film rolls, as shown in Figure 9 and Figure 10 , the film feeding mechanism 4 further comprises a counterweight roller slide 47 and a buffer counterweight roller 48. The buffer counterweight roller 48 is slidably connected to the counterweight roller slide 47, and is located on one side of the second position on the first path and on the outlet side of the film abutting device 45.

[0099] When the film roll on the first film roll holder 41 is released to a first length, the buffer counterweight roller 48 slides on the counterweight roller slide 47 to extend the first path to the second path. As shown in Figure 10 , the buffer counterweight roller 48 moves from the solid line position to the dashed line position, and the film material in the dashed line is the part added when the first path is extended to the second path.

[0100] When the film roll on the first film roll holder 41 continues to be released to a second length, the buffer counterweight roller 48 moves back on the counterweight roller slide 47, and the movement path of the film roll gradually recovers from the second path to the first path. The film abutting device 45 fixes the head end of the film roll of the second film roll holder 42 and the tail end of the film roll of the first film roll holder 41, and the film end positioning platform 44 releases the film roll of the second film roll holder 42.

[0101] At this time, the double-roll film holder cooperates with the buffer counterweight roller 48. Before the abutting operation of the film abutting device 45, the film roll on the first film roll holder 41 is changed from the first path to the second path, and the film roll is buffered on the outlet side of the film abutting device 45. During the abutting operation of the film abutting device 45, the buffer counterweight roller 48 resets, the movement path of the remaining film roll on the first film roll holder 41 recovers from the second path to the first path, and the length difference between the two paths makes the film material have a redundant length on the outlet side of the film abutting device 45, ensuring continuous and uninterrupted film feeding.

[0102] Exemplarily, the buffer counterweight roller 48 is a single horizontal roller; in other embodiments, according to different space margins and the time required for sealing, the buffer counterweight roller 48 can be replaced by a multi-axis swing arm, a multi-axis up-and-down roller group, or a multi-axis horizontal roller group instead of a single horizontal roller.

[0103] Furthermore, based on the setting of the buffer counterweight roller 48, during normal film feeding when the film rolls on the first film frame 41 or the second film frame 42 are not docked, the buffer counterweight roller 48 can act as a tension roller to press down the film material to ensure that the film material is taut.

[0104] For example, such as Figure 10 As shown, the membrane actuator 43 includes a servo winding mechanism 431 and a traction roller 433, with a buffer counterweight roller 48 positioned between the servo winding mechanism 431 and the traction roller 433. The buffer counterweight roller 48 can dynamically adjust the tension difference between the two active traction mechanisms, namely the servo winding mechanism 431 and the traction roller 433. The film material is continuously fed through the servo winding mechanism 431 and the traction roller 433. The positional change of the buffer counterweight roller 48 compensates for minor changes in the servo winding mechanism 431, maintaining the tension between the two active traction mechanisms, adjusting the film material to be on the first path, and ensuring continuous high-speed synchronous output of equal-length film rolls within each fixed time interval.

[0105] For example, a detection device is provided on or near the first film roll holder 41 to provide a signal to trigger the movement of the buffer counterweight roller 48 to buffer the film material. For example, the detection device can be a pressure sensor, a photoelectric sensor, or a timer to automatically determine the status of the film roll on the first film roll holder 41, such as whether it has been used or has remaining length, or whether it is almost used up. According to the signal from the detection device, the film docking device 45 and the film end positioning platform 44 automatically operate to automate the entire film roll renewal process; or the status of the film roll on the first film roll holder 41 can be determined manually, and instructions can be input to make the film docking device 45 and the film end positioning platform 44 operate.

[0106] In addition, in conjunction with the detection device on the first film roll holder 41, when the detection device warns that the film roll on the first film roll holder 41 has been released to the first length, the servo feeding mechanism 431 accelerates its movement, and the buffer counterweight roller 48 moves adaptively. After the buffer counterweight roller 48 moves into place, the film docking device 45 connects the new and old film rolls.

[0107] For example, such as Figure 9 and Figure 10 As shown, the membrane actuator 43 includes a conveying roller 432, a servo winding mechanism 431, and a traction roller 433. Multiple traction rollers 433 and multiple conveying rollers 432 can be provided. The film material sequentially passes through the conveying roller 432, the servo winding mechanism 431, the buffer counterweight roller 48, the limiter 49, the tube forming device 46, and the traction roller 433. The conveying roller 432, the servo winding mechanism 431, the limiter 49, and the tube forming device 46 are respectively located on one side of a position on the first path, while the traction roller 433 is located on the discharge side of the longitudinal sealing mechanism 5, ensuring continuous conveying of the film material after longitudinal and transverse sealing.

[0108] In the use of the film roll feeding mechanism 4, when the film roll on the first film roll holder 41 is running, it sequentially passes through the conveying roller 432, the servo roll feeding mechanism 431, the buffer counterweight roller 48, the position limiter 49, the cylinder former 46, and the traction roller 433. At this time, the film roll is continuously fed by the servo roll feeding mechanism 431 and the traction roller 433, and the buffer counterweight roller 48 changes its position to compensate for the slight change of the servo roll feeding mechanism 431, so as to maintain the film tension between the two active traction mechanisms and ensure that the film roll is continuously and synchronously output at a high speed in each fixed time period. When the film roll on the first film roll holder 41 is running, the new film roll on the second film roll holder 42 is placed on the film end positioning platform 44 by manual operation.

[0109] When the film roll on the first film roll holder 41 is about to run out, the sensor installed on the first film roll holder 41 sends a signal, and the servo roll feeding mechanism 431 accelerates to feed out the excess film roll. At this time, the buffer counterweight roller 48 reaches a limit position to save enough film material and give the new and old film rolls time to splice. When the old film roll is about to run out, the pressing block on the film butt joint device 45 presses the new and old film rolls together, and the film heat sealing heads on the two pressing blocks are symmetrically pressed in to heat seal and bond the two film rolls together. After that, the film heat sealing heads are opened, and the old film roll continues to supply the new film roll that is bonded together, i.e., the film roll on the second film roll holder 42 is supplied, and the buffer counterweight roller 48 gradually enters the normal working position.

[0110] In some embodiments, as shown in Figure 13 , the longitudinal sealing mechanism 5 includes a longitudinal sealing heating roller 51. The longitudinal sealing mechanism 5 can be arranged on one side of the feeding pipe 11, and the cylinder former 46 can also be wrapped on the outside of the feeding pipe 11. When the film material passes through the gap between the cylinder former 46 and the feeding pipe 11, a cylindrical shape is formed, and the two side edges are close to and face the longitudinal sealing mechanism 5, so that the two side edges can be directly sealed by the longitudinal sealing heating roller 51 to form a closed ring-shaped structure of the cylindrical film.

[0111] In some embodiments, as shown in Figure 14 and Figure 15 , the transverse sealing mechanism 6 includes a transverse sealing body 61, a transverse sealing swing driving assembly, and a transverse sealing lifting driving assembly 62. The transverse sealing swing driving assembly and the transverse sealing lifting driving assembly 62 are connected to the transverse sealing body 61 and respectively complete the seal c and seal b in Figure 12 . In combination with the orientation of Figure 13 , after the longitudinal sealing mechanism 5 completes the seal a in Figure 12 and forms the first cylinder, the first cylinder is moved downward along the feeding pipe 11 to a certain length below the feeding pipe 11, the transverse sealing body 61 is moved upward, and the seal b is completed.

[0112] Exemplarily, for the transverse sealing body 61, as shown in Figure 14 The transverse sealing body 61 includes two transverse sealing swing arms 64, and a transverse sealing swing driving assembly is used to drive the clamping ends of the two transverse sealing swing arms 64 to approach or move away from each other. The clamping end of at least one of the transverse sealing swing arms 64 is provided with a transverse sealing heating sealing block and a transverse sealing cutter 641. Optionally, the transverse sealing heating sealing block can be heated by a resistance wire or can be heated by ultrasonic waves to achieve heat sealing. Since the transverse sealing heating sealing block and the transverse sealing cutter 641 are both arranged on the transverse sealing swing arm 64, the timing of the cutter and the heat sealing action can be coordinated in milliseconds.

[0113] Specifically, when the clamping ends of the two transverse sealing swing arms 64 approach each other to close, the heating sealing blocks of the two transverse sealing swing arms 64 complete the heat sealing of the non-woven fabric. The transverse sealing swing arm 64 is also provided with a cutter control cylinder 642, and the transverse sealing cutter 641 is controlled by the cutter control cylinder 642. After the non-woven fabric is heat sealed by the heating sealing block, the transverse sealing cutter 641 is driven by the cutter control cylinder 642 to cut off the non-woven fabric.

[0114] Exemplarily, for the transverse sealing swing driving assembly, in order to achieve high-speed continuous sealing and cutting, as shown in Figure 14 and Figure 15 The transverse sealing swing driving assembly includes a swing arm control motor 63 and a first swing arm connecting rod assembly 69 connected between the swing arm control motor 63 and the transverse sealing swing arms 64. The first swing arm connecting rod assembly 69 is provided with a holding cylinder 693 for keeping the clamping ends of the two transverse sealing swing arms 64 in close contact for a set period of time. Specifically, the holding cylinder 693 continuously supplies air to generate a one-way pulling force, ensuring that the transverse sealing swing arms 64 remain in contact for a certain period of time and pressure when closing, thereby ensuring the sealing effect. At this time, the swing arm control motor 63 can continue to operate, while the holding cylinder 693 acts to ensure the close contact of the two clamping ends, thereby avoiding repeated start-stop of the swing arm control motor 63 and ensuring high-speed continuous transverse cutting of the bag body.

[0115] Exemplarily, the first swing arm connecting rod assembly 69 includes a crank rocker structure that can move reciprocally. As shown in Figure 14 and Figure 15 The crank rocker structure includes a second eccentric wheel 691, a second connecting rod assembly 692, the holding cylinder 693, and a third swing arm 694 connected in sequence. The second eccentric wheel 691 is connected to the swing arm control motor 63, and the third swing arm 694 is connected to one of the transverse sealing swing arms 64 to drive the transverse sealing swing arm 64 to swing. In addition, in order to achieve linkage, the first swing arm connecting rod assembly 69 further includes a follower 695 and a second swing arm 696. The follower 695 is connected to the third swing arm 694 and nested in the second swing arm 696, and the second swing arm 696 is connected to the other transverse sealing swing arm 64, so that the third swing arm 694 can drive the other transverse sealing swing arm 64 through the follower 695 and the second swing arm 696.

[0116] Exemplarily, to realize the unified lifting of the two transverse sealing swing arms 64 and avoid interference with the transverse sealing lifting driving assembly 62, the transverse sealing mechanism 6 further comprises a transverse sealing mounting frame 65 and two transverse sealing rotating shafts 66, which can be a first rotating shaft 661 and a second rotating shaft 662 respectively. The two transverse sealing rotating shafts 66 are rotationally connected to the transverse sealing mounting frame 65, for example, bearing connection, at this time, the transverse sealing mounting frame 65 cannot rotate through the limiting of the two transverse sealing rotating shafts 66. The two transverse sealing swing arms 64 are connected to the two transverse sealing rotating shafts 66 respectively, and the transverse sealing swing arms 64 can rotate synchronously with the corresponding transverse sealing rotating shaft 66, which can be key connection, for example, the transverse sealing rotating shaft 66 can be a spline shaft, and the transverse sealing swing arm 64 is spline-connected to the transverse sealing rotating shaft 66 to rotate synchronously. The transverse sealing swing arm 64 and the transverse sealing mounting frame 65 can slide synchronously on the transverse sealing rotating shaft 66, specifically, the transverse sealing swing arm 64 extends into the side groove of the transverse sealing mounting frame 65, and is clamped and limited by the groove top and the groove bottom of the side groove to slide synchronously on the transverse sealing rotating shaft 66.

[0117] Specifically, the first swing arm connecting rod assembly 69 connects the third swing arm 694 to the first rotating shaft 661 and the second swing arm 696 to the second rotating shaft 662. The first swing arm connecting rod assembly 69 drives the transverse sealing rotating shaft 66 to rotate to drive the transverse sealing swing arm 64 to rotate, and the transverse sealing lifting driving assembly 62 drives the transverse sealing mounting frame 65 to lift along the transverse sealing rotating shaft 66 to drive the transverse sealing swing arm 64 to lift with the transverse sealing mounting frame 65.

[0118] Exemplarily, as shown in Figure 14 and Figure 15 The transverse sealing lifting driving assembly 62 comprises a longitudinal control motor 67 and a second swing arm connecting rod assembly 68, and the longitudinal control motor 67 connects the transverse sealing mounting frame 65 through the second swing arm connecting rod assembly 68 to drive the transverse sealing mounting frame 65 to lift along the transverse sealing rotating shaft 66.

[0119] Specifically, the second swing arm connecting rod assembly 68 and the transverse sealing mounting frame 65 form a crank slider mechanism to realize the reciprocating lifting movement of the transverse sealing mounting frame 65 on the swing arm rotating shaft. For example, the second swing arm connecting rod assembly 68 comprises a first eccentric wheel 681, a first connecting rod assembly 682, a first swing arm 683 and a movable connecting rod 684 connected in sequence, the first eccentric wheel 681 is connected to the longitudinal control motor 67, and the movable connecting rod 684 is connected to the transverse sealing mounting frame 65. After the longitudinal control motor 67 is started, the transverse sealing mounting frame 65 is driven to move up and down on the transverse sealing rotating shaft 66 through the transmission of the second swing arm connecting rod assembly 68.

[0120] Exemplarily, the transverse sealing swing driving assembly takes the swing arm control motor 63 as the driving source, the transverse sealing lifting driving assembly 62 takes the longitudinal control motor 67 as the driving source, and specifically, both are servo motors, then the swing and lifting of the transverse sealing swing arm 64 are both realized by independent servo motors for motion control, thereby meeting the heat sealing and cutting of non-woven fabrics under different lengths and different speeds, realizing the high matching of the longitudinal sealing, transverse sealing and cutting functions of non-woven fabrics under high-speed continuous operation, realizing the millisecond-level cooperation of longitudinal sealing, transverse sealing and cutting, realizing high-speed continuous packaging, and greatly improving the production efficiency and automation level. Alternatively, in other embodiments, the swing arm control motor 63 and the longitudinal control motor 67 can also be replaced by one motor matched with a cross commutator to realize double-output shaft control.

[0121] In a use process, when producing nicotine sachets, after the nicotine sachets pass through the continuously moving longitudinal sealing heating roller 51 to complete the longitudinal sealing of the direction of non-woven fabric movement, transverse sealing and cutting are performed, the transverse sealing is completed in the direction perpendicular to the movement direction of the non-woven fabric; the charging mechanism charges through the charging pipe 11, and at the same time, the transverse sealing mounting frame 65 drives the transverse sealing swing arm 64 to reciprocally move upward on the spline shaft pair to top-seal the nicotine sachets after charging, thereby generating a complete nicotine sachet; the transverse sealing mounting frame 65 drives the transverse sealing swing arm 64 to reciprocally move up and down during the high-speed non-woven fabric charging process, thereby realizing reciprocating length transverse sealing and cutting.

[0122] The packaging machine in the embodiment of the application systematically solves the pain points of high-humidity nicotine bag packaging, realizes high efficiency (more than 300 bags per minute), high reliability (pipe blockage rate <5%), high safety (full automation) through the innovative design of film roll non-stop replacement, spiral oscillation charging, double air pressure anti-blocking and high-speed sealing and cutting cooperation, and is downward compatible with multiple processes. These advantages not only improve the production capacity by 30-50%, but also reduce the operating cost.
