[0052] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0053] This utility model provides a high-speed continuous roll film forming vertical packaging machine, such as... Figures 1 to 30 As shown, the high-speed continuous roll film forming vertical packaging machine includes a frame 1, an automatic coding and correction movable film feeding frame 2, a vacuum film pulling continuous longitudinal sealing device 3, and a reciprocating follow-up cutting sealing device 4.

[0054] The frame 1 is provided with a receiving cavity 11. One side of the frame 1 is provided with an opening 12, and the other side of the frame 1 is provided with a discharge port 14. The top of the frame 1 is provided with a feeding port 13. The feeding end of the automatic coding and correction movable film feeding frame 2 is placed in the receiving cavity 11 through the opening 12. The vacuum film stretching continuous longitudinal sealing device 3 and the reciprocating chasing and shearing sealing device 4 are both provided in the receiving cavity 11. The feeding hopper 311 of the vacuum film stretching continuous longitudinal sealing device 3 is located at the position of the feeding port 13, and the discharge guide groove 441 of the reciprocating chasing and shearing sealing device 4 corresponds to the discharge port 14.

[0055] When packaging items, the automatic coding and correction movable film feeder 2 unfolds the film roll and conveys the unfolded bag film to the vacuum film stretching continuous longitudinal sealing device 3. The vacuum film stretching continuous longitudinal sealing device 3 forms and seals the bag film, thereby forming an upper through bag structure. The reciprocating cutting and sealing device seals the bag body, thereby forming a sealed packaging bag. During the sealing and cutting process, the items to be packaged fall into the packaging bag through the feed hopper 311, thus completing the packaging of the items. The packaged items continue to fall into the discharge guide trough 441 and are discharged from the discharge port 14.

[0056] In the aforementioned process, the automatic coding and correction movable film feeder 2 can automatically correct the deviation of the bag film, thereby ensuring the subsequent packaging effect.

[0057] The vacuum film stretching continuous longitudinal sealing device ensures continuous longitudinal sealing, guaranteeing packaging efficiency while maintaining the sealing and bag forming effects.

[0058] The reciprocating follow-cut sealing device is a follow-cut sealing device, which completes horizontal sealing and cutting during the bag conveying process without interruption, thereby further improving packaging efficiency.

[0059] The frame 1, the automatic coding and correction movable film feeding frame 2, the vacuum film pulling continuous longitudinal sealing device 3, and the reciprocating follow-up cutting sealing device 4 work together to achieve not only high packaging efficiency but also significant packaging effect.

[0060] As an optional implementation, such as Figures 4 to 12 As shown, the automatic coding and correction movable film feeder 2 includes a movable film feeder 21, an unwinding and film feeding mechanism 22, a coding mechanism 23, a correction mechanism 24, and a swing arm tensioning mechanism 25.

[0061] The unwinding and film feeding mechanism 22, the coding mechanism 23, and the swing arm tensioning mechanism 25 are all mounted on the movable film feeding frame 21. The correction mechanism 24 is connected to the movable film feeding frame 21. The swing arm tensioning mechanism 25 includes a tensioning power assembly and a swing-type tensioning roller assembly connected to the tensioning power assembly.

[0062] During operation, the unwinding and film feeding mechanism 22 drives the film roll to open and guides the unfolded bag film to move. During this process, the tensioning power component drives the oscillating tensioning roller assembly to maintain the bag film tension at a constant level. The coding mechanism 23 then codes the bag film to facilitate subsequent sealing and cutting.

[0063] During the aforementioned bag film conveying process, when the bag film deviates, the correction mechanism 24 drives the movable film feeding frame 21 to move, thereby correcting the deviation of the bag film and ensuring that the bag film can accurately correspond to the forming device, thus guaranteeing the subsequent bag film forming effect.

[0064] As an optional implementation, the unwinding and film feeding mechanism 22 includes an unwinding assembly 221, which includes an unwinding power assembly 2211, a chuck 2212, and an air shaft 2213.

The chuck 2212 clamps the connecting end of the air shaft 2213. The mounting end of the air shaft 2213 is rotatably mounted on the movable film feeder 21. The air shaft 2213 is used to mount the film roll.

[0067] During operation, the unwinding power assembly 2211 drives the chuck 2212 and the air shaft 2213 to rotate synchronously, thereby opening the film mounted on the air shaft 2213.

[0068] As an optional implementation, the unwinding and feeding film mechanism 22 includes a film receiving platform 222, which includes a film receiving table 2221 and a film receiving pressure bar assembly 2222.

Each film-attaching pressure bar has a cam handle 2223 above its end. The pressing end of the cam handle 2223 is hinged to a guide rod 2224. The guide rod 2224 slides through the film-attaching pressure bar and the film-attaching platform 2221. A spring 2225 is sleeved on the guide rod 2224 and abuts against the film-attaching pressure bar and the film-attaching platform 2221. When pressing the bag film, the cam handle 2223 is turned, and the cam handle 2223 presses against the corresponding film-attaching pressure bar, thereby pressing the bag film. The spring 2225 acts as a buffer.

[0071] As an optional implementation, the unwinding and film feeding mechanism 22 includes a guide roller assembly 223, which includes a plurality of guide rollers 2231 arranged in sequence.

The ribbon cassette 232 and the printing roller 231 are located on both sides of the bag film, respectively.

[0075] As an optional implementation, the correction mechanism 24 includes a correction motor 241 and a correction actuator 242 connected to the correction motor 241.

The guide sleeve 211 is slidably sleeved on the sliding shaft 212. The guide sleeve 211 and the sliding shaft 212 cooperate with each other to effectively limit the movement trajectory of the movable film feeding frame 21.

[0077] When the bag film deviates, the correction motor 241 starts, driving the correction actuator 242 to extend and retract, thereby driving the movable film feeder 21 to move along the sliding shaft 212, thus realizing correction. The electric correction method has a rapid response, high precision, and significant correction effect.

[0078] As an optional implementation, the tensioning power assembly is configured as a tensioning telescopic assembly 251, and the oscillating tensioning roller assembly includes an oscillating arm 252 and a film-feeding roller 253.

The number of film feeding rollers 253 is set to multiple, and the film feeding rollers 253 are rotatably mounted between the two swing arms 252.

[0080] When adjusting the bag film tension, the telescopic end of the tensioning telescopic component 251 moves, causing the swing arm 252 to swing, thereby tensioning the bag film and achieving tension adjustment.

[0081] As an optional implementation, the swing arm tensioning mechanism 25 includes an angle sensor, which is located at a position corresponding to the fixed end of a swing arm 252. The angle sensor can monitor the tension adjustment by detecting the swing angle of the swing arm 252.

[0091] The continuous longitudinal sealing mechanism 33 includes a longitudinal sealing support 331, a continuous longitudinal sealing assembly 332, and a distance adjustment assembly 333. The distance adjustment assembly 333 is fixedly mounted on the longitudinal sealing support 331 and connected to the continuous longitudinal sealing assembly 332.

[0092] During operation, the film is formed into a bag body by the feeding and forming mechanism 31. The vacuum film stretching mechanism 32 assists in the forming of the bag body on the one hand, and is used for bag body conveying on the other hand. During the movement of the bag body, the continuous longitudinal sealing component 332 heat seals the seam of the bag body.

[0093] During the above process, depending on the thickness of the bag film, the distance between the continuous longitudinal sealing component 332 and the feeding and forming mechanism 31 can be adjusted to a suitable distance by the distance adjustment component 333, thereby effectively ensuring the longitudinal sealing effect.

[0094] As an optional implementation, the distance adjustment component 333 includes an adjustment screw 3331 and a sliding guide component. The sliding guide component includes a sliding guide 3333 and a slide rod 3332. The sliding guide 3333 is fixedly mounted on the longitudinal sealing bracket 331. The sliding guide 3333 has a threaded hole 33331 and a guide hole 33332 through it. The longitudinal sealing bracket 331 is configured as a frame structure.

[0095] The adjusting end of the adjusting screw 3331 is fixedly provided with a handle. The connecting end of the adjusting screw 3331 passes through the threaded hole 33331 and is rotatably connected to the continuous longitudinal sealing assembly 332. The adjusting screw 3331 is threadedly engaged with the threaded hole 33331.

[0096] The screw-type adjustment structure allows for easy distance adjustment simply by rotating the screw, while also providing a self-locking function to ensure a more stable adjustment position.

The slide rod 3332 and the guide hole 33332 are in sliding engagement. The sliding guide 3333 and the slide rod 3332 cooperate with each other to effectively limit the movement trajectory of the continuous longitudinal sealing assembly 332 during the distance adjustment process.

[0098] When adjusting the distance, rotate the handle, and the adjusting screw 3331 rotates synchronously. Under the guidance and limiting action of the slide bar 3332, the adjusting screw 3331 moves axially, thereby driving the continuous longitudinal sealing assembly 332 to move synchronously and complete the adjustment.

[0099] As an optional implementation, the continuous longitudinal sealing assembly 332 includes a longitudinal sealing mounting assembly 3321, a longitudinal sealing power assembly 3322, a longitudinal sealing drive wheel 3323, a longitudinal sealing driven wheel 3324, a longitudinal sealing steel belt 3325, a longitudinal sealing telescopic assembly 3326, and a heating block 3327.

[0100] The connecting end of the slide bar 3332 is fixedly connected to the longitudinal sealing mounting assembly 3321.

[0101] The longitudinal sealing power assembly 3322 is an electric power assembly, including a servo motor, which is fixedly mounted on the longitudinal sealing mounting assembly 3321.

[0102] The driven wheel 3324 of the longitudinal seal is rotatably mounted on the longitudinal seal mounting assembly 3321 and is connected to the driving wheel 3323 of the longitudinal seal via the longitudinal seal steel belt 3325.

[0103] The fixed end of the longitudinal sealing telescopic assembly 3326 is rotatably connected to the connecting end of the adjusting screw 3331, and the telescopic end of the longitudinal sealing telescopic assembly 3326 is connected to the longitudinal sealing mounting assembly 3321; the longitudinal sealing telescopic assembly 3326 is preferably a pneumatic telescopic assembly, including a cylinder.

[0104] The heating block 3327 is located inside the longitudinal sealing steel strip 3325 and slides in cooperation with the longitudinal sealing steel strip 3325.

[0105] During the longitudinal sealing process, the longitudinal sealing power component 3322 drives the longitudinal sealing drive wheel 3323 to rotate. With the assistance of the longitudinal sealing driven wheel 3324, the longitudinal sealing steel belt 3325 rotates. At the same time, the longitudinal sealing telescopic component 3326 extends, causing the rotating longitudinal sealing steel belt 3325 to contact the seam of the bag. At this time, the heating block 3327 heats up, and the longitudinal sealing steel belt 3325 heats up the seam of the bag.

[0106] The use of a belt structure with continuous longitudinal sealing can significantly improve production efficiency.

[0107] As an optional implementation, the continuous longitudinal sealing assembly 332 further includes an elastic support assembly, which includes a support shaft 3328 and a spring sheet 3329.

[0110] The two ends of the longitudinal sealing bracket 331 are rotatably connected to the first support mechanism 34 via quick-release pins 3311.

[0111] In actual use, the longitudinal sealing bracket 331 can be flipped by disassembling the quick-release pin 3311 at one end of the longitudinal sealing bracket 331, which facilitates the later maintenance of the device.

The opening bag support structure 314 is used to open the bag body to facilitate subsequent horizontal sealing.

[0115] The collar forming device 313 is installed on the feed pipe 312 and located below the feed hopper 311. After the bag film passes through the collar forming device 313, it can cover the feed pipe 312 to form an enclosed bag structure, which facilitates subsequent longitudinal sealing.

[0116] As an optional implementation, the vacuum film stretching continuous longitudinal sealing device 3 includes a film feeding roller mechanism 35, which includes a plurality of parallel film feeding rollers. The bag film conveyed by the film feeding rollers can be wrapped onto the feed pipe 312 by the collar forming device 313.

[0117] The film feeding roller mechanism 35 is used to transport the bag film.

[0118] As an optional implementation, the vacuum film stretching mechanism 32 includes a clamping drive assembly 322 and two vacuum film stretching assemblies 321 symmetrically arranged on both sides of the blanking and forming mechanism 31, with the two vacuum film stretching assemblies 321 connected to the clamping drive assembly 322.

[0119] During the longitudinal sealing process, the clamping drive assembly 322 is activated, driving the two vacuum film stretching assemblies 321 to move towards each other and clamp against both sides of the feed tube 312, thereby adsorbing and conveying the bag.

[0120] As an optional implementation, the clamping drive assembly 322 includes a film stretching telescopic assembly 3221 and a horizontal guide assembly. The film stretching telescopic assembly 3221 is a pneumatic telescopic assembly, including a cylinder.

[0121] The number of membrane stretching components 3221 is set to two, and the two membrane stretching components 3221 are symmetrically arranged. The stretching ends of the two membrane stretching components 3221 are respectively connected to the two vacuum membrane stretching components 321.

[0122] The telescopic component provides power for the opposite movement of the two vacuum film stretching components 321, which is simple in structure and has a significant effect.

[0123] The horizontal guide assembly includes a horizontal guide 3222 and two sets of sliding members 3223 slidably disposed on the horizontal guide 3222. The horizontal guide 3222 is configured as a slide rail and is fixedly disposed on the first support mechanism 34. The sliding members 3223 are configured as sliders. The two sets of sliding members 3223 are respectively fixedly connected to two vacuum film stretching assemblies 321.

[0124] The horizontal guide component can effectively limit the movement trajectory of the vacuum film stretching component 321.

[0125] As an optional implementation, the vacuum film stretching assembly 321 includes a film stretching power assembly 3211, a film stretching drive wheel 3212, a film stretching driven wheel 3213, a film stretching adsorption belt 3214, a vacuum block 3215, and a vacuum tube 3216.

[0126] The membrane stretching power assembly 3211 is an electric power assembly, including a servo motor. Its output end is connected to the membrane stretching drive wheel 3212 and can drive the membrane stretching drive wheel 3212 to rotate. The membrane stretching driven wheel 3213 is connected to the membrane stretching drive wheel 3212 through the membrane stretching adsorption belt 3214. Adsorption grooves are evenly arranged on the membrane stretching adsorption belt 3214. The vacuum block 3215 is located inside the membrane stretching adsorption belt 3214, and the adsorption port of the vacuum block 3215 faces the membrane stretching adsorption belt 3214. The vacuum block 3215 is connected to the vacuum tube 3216.

[0127] When the bag is being transported, the film-pulling power assembly 3211 is activated, driving the film-pulling drive wheel 3212 to rotate. With the assistance of the film-pulling driven wheel 3213, the film-pulling adsorption belt 3214 rotates. At the same time, the vacuum tube 3216 evacuates air from the vacuum block 3215, creating a negative pressure in the adsorption groove of the film-pulling adsorption belt 3214, thereby adsorbing the bag and causing it to move with the film-pulling adsorption belt 3214, thus realizing the transport of the bag.

[0128] As an optional implementation method, such as Figures 21 to 30 As shown, the reciprocating shearing sealing device 4 includes a reciprocating lifting mechanism 41, a horizontal sealing heat sealing mechanism 42, and a telescopic cutting mechanism 43.

[0129] The reciprocating lifting mechanism 41 includes a lifting drive assembly 411 and a lifting frame 412. The lifting drive assembly 411 is connected to the lifting frame 412 and can drive the lifting frame 412 to reciprocate in the vertical direction.

[0130] The horizontal sealing heat sealing mechanism 42 is mounted on the lifting frame 412 and moves synchronously with the lifting frame 412. The action of the horizontal sealing heat sealing mechanism 42 can heat seal the bag body.

[0131] The telescopic cutting mechanism 43 is mounted on the horizontal sealing heat sealing mechanism 42 and can move with the horizontal sealing heat sealing mechanism 42. The telescopic cutting mechanism 43 can cut the bag body by telescopic movement.

[0132] During operation, the lifting drive assembly 411 drives the lifting frame 412 to reciprocate, thereby driving the horizontal sealing heat sealing mechanism 42 and the telescopic cutting mechanism 43 to reciprocate in a synchronous manner. Thus, during the bag conveying process, the horizontal sealing heat sealing mechanism 42 and the telescopic cutting mechanism 43 can track the moving speed of the bag.

[0133] At the same time, the horizontal sealing heat sealing mechanism 42 operates to heat seal the corresponding position of the bag. During the heat sealing process, the telescopic cutting mechanism 43 telescopically operates to cut the bag.

[0134] By setting the telescopic cutting mechanism 43 on the horizontal sealing heat sealing mechanism 42, it is possible to cut simultaneously with the heat sealing process, ensuring uninterrupted production and significantly improving work efficiency while maintaining the sealing effect.

[0135] As an optional implementation, the reciprocating lifting mechanism 41 includes a multi-cylinder buffer assembly 413, which includes at least two buffer cylinders 4131. The buffer cylinders 4131 are disposed above the lifting frame 412, and the buffer extension end is connected to the lifting frame 412.

[0143] The first end of the swing arm 4113 is rotatably connected to the first swing member 4112, and the second end of the swing arm 4113 is rotatably connected to the lifting frame 412.

[0144] The first swing member 4112, the swing arm 4113 and the lifting frame 412 cooperate with each other to form a crank-slider mechanism, which can effectively convert the reciprocating swing of the first swing member 4112 into the reciprocating lifting of the lifting frame 412.

Both the first heat sealing knife 4221 and the second heat sealing knife 4222 are connected to the horizontal drive assembly 421 for transmission.

[0147] During heat sealing, the horizontal drive assembly 421 drives the first heat sealing knife 4221 and the second heat sealing knife 4222 to move towards each other to complete the heat sealing of the bag. After the heat sealing is completed, the horizontal drive assembly 421 drives the first heat sealing knife 4221 and the second heat sealing knife 4222 to move away from each other.

[0148] As an optional implementation, the horizontal drive assembly 421 includes a horizontal power assembly 4211, a second swing member 4212, a first linkage arm 4213 and a second linkage arm 4214. The horizontal power assembly 4211 is an electric power assembly, including a servo motor.

[0149] The output end of the horizontal power component 4211 is connected to the middle position of the second swing member 4212 and can drive the second swing member 4212 to swing back and forth.

[0150] The two ends of the second swing member 4212 are rotatably connected to the first linkage arm 4213 and the second linkage arm 4214 respectively.

The first heat sealing knife 4221 and the second heat sealing knife 4222 are respectively disposed on the first heat sealing beam 4215 and the second heat sealing beam 4216.

[0151] Thus, a bidirectional crank-slider mechanism is formed, which can effectively convert the reciprocating oscillation of the second swing member 4212 into the reciprocating motion of the first heat sealing knife 4221 and the second heat sealing knife 4222, thereby realizing the opposite and opposite motions.

[0155] The first heat-sealing beam 4215 is slidably mounted on the slide rod 4232. The elastic buffer 4233 is a spring, which is sleeved on the slide rod 4232 and its two ends abut against the first heat-sealing beam 4215 and the limiting cap 4234, respectively. The elastic buffer 4233 mainly plays a buffering role. The horizontal guide 4231 has a guide groove along the axial direction. The second heat-sealing beam 4216 is slidably mounted on the guide groove. Furthermore, the second heat-sealing beam 4216 has a through guide hole. The second heat-sealing beam 4216 is slidably sleeved on the slide rod 4232 through the guide hole. The second heat-sealing beam 4216 is rotatably connected to the second linkage arm 4214.

[0156] Preferably, the number of horizontal guide components 423 is set to two.

[0157] The horizontal guide component 423 can effectively limit the movement trajectory of the heat sealing beam, thereby limiting the movement mechanism of the heat sealing knife and making the movement process more stable.

[0158] As an optional implementation, the telescopic cutting mechanism 43 is mounted on the first heat-sealing beam 4215 and moves synchronously with the first heat-sealing beam 4215; thus, during the heat-sealing process, the telescopic cutting mechanism 43 feeds along with it, which can effectively reduce the telescopic stroke of the telescopic cutting mechanism 43, so that the telescopic cutting mechanism 43 can complete the cutting of the bag body with only a small range of telescopic movement.

[0159] The telescopic cutting mechanism 43 includes a horizontal telescopic component 431 and a serrated cutter 432. The horizontal telescopic component 431 is a pneumatic telescopic component, including a cylinder.

The telescopic end of the horizontal telescopic component 431 is connected to the serrated cutter 432 through a connector 433. A guide groove 4223 is provided through the first heat-sealing cutter 4221 in the horizontal direction.

[0160] Preferably, the connector 433 is configured as a frame structure, and the horizontal telescopic component 431 is disposed inside the connector 433.
