Description

Technical Field

[0001] This invention relates to the field of express packaging machine technology, and in particular to an express packaging machine for continuous roll bags. Background Technology

[0002] The first-generation traditional express delivery tubular film packaging model involved professional tubular film manufacturers pre-processing unsealed, unopened tubular film into finished tubular film tubular films of various specifications with sealed bottoms and semi-openings, which were then fed into express delivery packaging machines. This type of equipment could only continuously use the same specification of film rings for a relatively long production period, and could only switch to other specifications after the entire roll of film was used up. Packaging the same specification of items typically required more than 2000 pieces, making the changeover process extremely cumbersome and completely unsuitable for scenarios involving the mixed production of multiple specifications of items.

[0003] The second-generation adaptive bag-making prototype machine achieved a major technological breakthrough by directly using unprocessed raw film tubes for production, eliminating the need for pre-formed continuous loop bag film rings. However, this type of equipment is still essentially a batch production mode, capable of producing only a single fixed-length film bag at a time. If it is necessary to switch to packaging different sizes of items, the machine must be stopped for reconfiguration and adjustments, and more than ten pre-made film bags of the previous size must be scrapped before the new size product can be produced normally. It cannot respond to the size requirements of different items in real time and cannot achieve true instant adaptive mixed production.

[0004] With the rapid development of the e-commerce and express delivery industry, and the gradual promotion of automatic visual recognition technology and packaging robot technology, the production model of leading express and e-commerce customers has evolved from traditional manual sorting and batch packaging according to specifications to fully intelligent real-time sorting and packaging based on robots and CCD vision technology. This eliminates the large-scale pre-sorting and material distribution process, directly enabling real-time mixed production of items of different sizes and specifications. However, most small and medium-sized logistics and e-commerce customers only package hundreds to thousands of items per day. Although their existing packaging equipment supports the production of bags from the original film tubes, changing the type requires machine downtime, resulting in wasted film bags. It is also impossible to synchronize bag specifications with changes in item specifications, which reduces production efficiency. Therefore, existing packaging equipment is completely unsuitable for this type of flexible production scenario with small batches and multiple SKUs. Summary of the Invention

[0005] To overcome the problems of existing packaging equipment being unable to synchronize bag sizes with changes in item specifications and not supporting simultaneous packaging of multiple item sizes, this invention provides a continuous roll bag express packaging machine.

[0034] Example 1 To overcome the problem that existing packaging equipment cannot synchronize changes in bag size with changes in item specifications and does not support simultaneous packaging of multiple item sizes, this invention provides a continuous roll bag express packaging machine.

[0035] This embodiment discloses a continuous roll bag express packaging machine, such as... Figures 1-2 As shown, it includes a frame 10 and a sealing and cutting mechanism 20, a bag exiting mechanism 30 and a bag opening and sealing mechanism 40 arranged sequentially on the frame 10 along the conveying direction of the continuous roll film bag 100.

[0036] In this embodiment, the sealing and cutting mechanism 20 is used to perform bottom heat sealing and toothed cutting on the output roll film bag 100 that matches the specifications of the item; The bag delivery mechanism 30 is used to convey the continuous roll film bag 100 that matches the specifications of the item, and to pull open the upper layer of the continuous roll film bag 100 that has completed bottom heat sealing and toothed tangent along the toothed tangent, and to pull open the lower layer of the continuous roll film bag 100 that has completed feeding and sealing along the toothed tangent. The bag opening and sealing mechanism 40 is used to open the continuous roll film bag 100 output by the bag dispensing mechanism 30 and seal the continuous roll film bag 100 after feeding. The bag-discharging mechanism 30 includes an active roller 31, a driven roller 32, a first drive assembly 33, and a control component 34. The active roller 31 and the driven roller 32 are distributed vertically, and a bag-discharging channel is formed between the active roller 31 and the driven roller 32 for the continuous roll film bag 100 to pass through and enter the bag-seal mechanism 40. The first drive assembly 33 is connected to the active roller 31 to drive the active roller 31 to drive the driven roller 32 to rotate. The control component 34 is connected to the driven roller 32 to tighten or loosen the driven roller 32.

[0037] The working process of the continuous roll bag express packaging machine in this embodiment is as follows: the control component 34 is released, and the active roller 31 drives the driven roller 32 to rotate relative to each other under the drive of the first drive component 33 to convey the continuous roll film bag 100 that matches the item specifications. After the continuous roll film bag 100 that matches the item specifications is in place, the active roller 31 and the driven roller 32 stop rotating, and the control component 34 clamps the driven roller 32 to complete the output of the continuous roll film bag 100. The sealing and cutting mechanism 20 starts working to complete the bottom heat sealing and toothed cutting of the output continuous roll film bag 100 that matches the item specifications. After the sealing and cutting mechanism 20 completes the bottom heat sealing and toothed cutting, it continues to press the continuous roll film bag 100. The active roller 31 rotates a certain angle under the drive of the first drive component 33. Since the driven roller 32 is clamped and kept still by the control component 34, it does not rotate with the active roller 31, so that the upper layer of the continuous roll film bag 100 is cut along the toothed shape during the rotation of the active roller 31. The line is pulled open, completing the pre-made opening cavity; the sealing and cutting mechanism 20 rises to separate from the continuous roll film bag 100, the control component 34 is released, and the active roller 31 drives the driven roller 32 to rotate relative to each other under the drive of the first drive component 33, conveying the pre-made opening continuous roll film bag 100 to the work position of the bag opening and sealing mechanism 40. The bag opening and sealing mechanism 40 opens the continuous roll film bag 100 along the pre-made opening, and puts the items to be packaged into the continuous roll film bag 100; after the items are put in, the bag opening and sealing mechanism 40 seals the continuous roll film bag 100. After the bag opening and sealing mechanism 40 completes the sealing, it continues to press the continuous roll film bag 100. The active roller 31 drives the driven roller 32 to rotate under the drive of the first drive component 33, so as to break the bottom layer of the continuous roll film bag 100 along the toothed tangent. The bag opening and sealing mechanism 40 is released, and the packaged item bag falls onto the conveyor line for output, completing the entire express film bag packaging process.

[0038] This embodiment provides a continuous roll bag express packaging machine. The bag output mechanism 30 can output continuous roll film bags 100 of corresponding length according to the specifications of the items. There is no need to stop the machine to change the type or adjust the machine. There is also no problem of scrapping more than ten pre-made film bags when changing specifications. It realizes the function of real-time adaptive mixed production and perfectly adapts to the fully intelligent real-time sorting and packaging scenario of CCD vision and robots.

[0039] Furthermore, the bag-discharging mechanism 30 can simultaneously complete the conveying of continuous roll film bags 100, the pre-formed bag opening cavity, and the detachment of finished products, simplifying the overall transmission structure of the machine and reducing the equipment failure rate.

[0040] In this preferred embodiment, the continuous roll bag express packaging machine further includes a barcode scanning mechanism (not shown in the attached drawings) and a bag feeding mechanism 50. The barcode scanning mechanism is installed on the frame 10 and is used to scan the conveyed items to determine the size of the items. The bag feeding mechanism 50 is installed on the frame 10 and located on the input side of the sealing and cutting mechanism 20. The bag feeding mechanism 50 is used to feed the continuous roll film bag 100 and cooperates with the bag output mechanism 30 to convey the continuous roll film bag that matches the size of the items.

[0041] In this embodiment, the barcode scanning mechanism is communicatively connected to the first drive component 33 of the bag dispensing mechanism 30, so that the bag dispensing mechanism 30 can deliver the corresponding length of the continuous roll film bag 100 according to the size of the item obtained by the barcode scanning mechanism.

[0042] In this embodiment, the scanning mechanism uses a barcode scanner or a CCD industrial camera to scan the three-dimensional volume parameters of the item in real time and output the corresponding length of film feeding instruction instantly. The bag output mechanism 30 accurately matches the size of the item and outputs the corresponding length of continuous roll film bag 100.

[0043] The bag feeding mechanism 50 includes a support frame with several guide rollers. The continuous roll film bag 100 is in contact with the several guide rollers so that it can be transported to the sealing and cutting mechanism 20 through the bag feeding mechanism 30.

[0044] The bag feeding mechanism 50 in this embodiment is mainly used to unfold and transport the roll-shaped continuous film bag 100, and to adjust the transport position, transport angle and transport tension of the continuous film bag 100 during the transport process, so that the continuous film bag 100 can be transported with high precision.

[0045] This embodiment is a preferred embodiment, such as Figure 3 As shown, the first drive assembly 33 includes a first synchronous pulley 331, a first synchronous belt 332, and a first drive motor 333. The first synchronous pulley 331 is mounted on the frame 10 and connected to the drive roller 31. The first synchronous belt 332 is wound around the first synchronous pulley 331. The first drive motor 333 is connected to the first synchronous pulley 331 to drive the first synchronous pulley 331 to rotate. The control unit 34 includes a brake or a second drive motor.

[0046] In this embodiment, the first synchronous pulley 331 is driven by the first drive motor 333 to rotate the first synchronous belt 332, which can precisely control the rotation angle of the active roller 31, thereby improving the conveying accuracy of the continuous roll film bag 100 and perfectly adapting to the bag making length requirements of different specifications of items.

[0047] The driven roller 32 is controlled by the control element 34, thereby enabling independent control of the driving roller 31 and the driven roller 32.

[0048] This embodiment is a preferred embodiment, and the specific structure of the sealing and cutting mechanism 20 has been optimized.

[0049] In this embodiment, as Figures 5-6 As shown, the sealing and cutting mechanism 20 includes a mounting frame 21, a lifting drive assembly 22, a first heat sealing assembly 23, and a cutting assembly 24. The first heat sealing assembly 23 and the cutting assembly 24 are arranged sequentially along the conveying direction of the continuous roll film bag 100. The first heat-sealing assembly 23 and the cutting assembly 24 are movably mounted on the mounting frame 21. The lifting drive assembly 22 is fixedly mounted on the mounting frame 21. The output end of the lifting drive assembly 22 is connected to the first heat-sealing assembly 23 and the cutting assembly 24 to drive the heat-sealing assembly and the cutting assembly 24 to move up and down along the mounting frame 21.

[0050] In this embodiment, the lifting drive component 22 synchronously drives the first heat sealing component 23 and the cutting component 24 to move, ensuring that toothed cutting is performed synchronously immediately after heat sealing, thus avoiding uneven sealing edges and misaligned cutting lines caused by the displacement of the continuous roll film bag 100.

[0051] Preferably, the mounting frame 21 includes a top plate 211 and a bottom plate 212, the top plate 211 and the bottom plate 212 are arranged in parallel and the top plate 211 and the bottom plate 212 are fixedly connected by guide columns 213, and the lifting drive assembly 22 is fixedly connected to the top plate 211. The first heat sealing assembly 23 includes a first pressing module 231 and a first heat sealing module 232 disposed opposite to each other. The first pressing module 231 is connected to the output end of the lifting drive assembly 22, and the first heat sealing module 232 is disposed on the base plate 212. The cutting assembly 24 includes a toothed cutting module, which is connected to the output end of the lifting drive assembly 22.

[0052] Preferably, the first pressing module 231 is made of silicone, the first heat sealing module 232 is made of heat sealing strip, and the first pressing module 231 and the first heat sealing module 232 cooperate to heat seal the continuous roll film bag 100; the toothed cutting module includes toothed blades.

[0053] In this embodiment, the top plate 211 and the bottom plate 212 are fixedly connected by the guide column 213. The first pressing module 231 and the tooth cutting module move up and down along the guide column 213 under the drive of the lifting drive component 22, thereby ensuring that the first pressing module 231 and the tooth cutting module move vertically up and down without lateral deviation during operation. Even after long-term use, there will be no uneven wear of the first heat sealing module 232 or the tooth cutting module will not cause any faults, thus greatly extending the service life of the core components of the whole machine.

[0054] The first pressing module 231 first presses and fixes the continuous roll film bag 100, and then works with the first heat sealing module 232 below to complete the heat sealing, so as to avoid wrinkling of the continuous roll film bag 100 during the heat sealing process, ensure that the sealing edge is firmly bonded and leak-proof, and meet the waterproof and leak-proof packaging requirements of express parcels.

[0055] Preferably, the cutting assembly 24 further includes a pad or a cutting groove, which is disposed on the base plate 212 and is disposed opposite to the toothed cutting module.

[0056] This embodiment provides a pad or groove structure on the base plate 212 that matches the toothed cutting module. The rigid pad provides sufficient support to ensure that the toothed cutting line completely cuts the non-heat-sealed layer of the continuous film bag 100. Alternatively, an embedded groove is used to allow the toothed blade to be fully inserted into the groove, avoiding direct hard contact between the toothed blade and the rigid component, which would cause tooth breakage. While ensuring that the toothed cut is uniform and continuous and has a good tearing effect, this embodiment significantly reduces the wear frequency of the toothed blade of the toothed cutting module and extends the toothed blade replacement cycle.

[0057] Preferably, along the conveying direction of the continuous roll film bag 100, the toothed cutting module is fixedly installed on the output side of the first heat sealing assembly 23, and the output end of the lifting drive assembly 22 is connected to the first pressing module 231 and / or the toothed cutting module through the guide plate 25.

[0058] In this embodiment, the sealing and cutting mechanism 20 first completes the heat sealing of the bottom of the continuous roll film bag 100 through the first heat sealing component 23, and then performs toothed cutting through the cutting component 24 to ensure that the bottom of the heat-sealed bag is fully formed before the toothed cutting line is cut, so that the problem of bag leakage at the bottom caused by the heat-sealed edge being cut by the toothed knife will not occur.

[0059] In addition, the shared guide plate 25 synchronously drives the first pressing module 231 and the toothed cutting module, reducing the number of independent driving components, simplifying the control logic of the sealing and cutting mechanism 20, and reducing the difficulty of equipment maintenance.

[0060] In this preferred embodiment, the sealing and cutting mechanism 20 further includes a punching module 26. Along the conveying direction of the continuous roll film bag 100, the punching module 26 is disposed on the input side of the first heat sealing assembly 23 and fixedly connected to the first pressing module 231.

[0061] The continuous roll bag express packaging machine provided in this embodiment integrates a punching module 26 on the heat sealing input side of the sealing and cutting mechanism 20. This module can simultaneously complete the air hole processing of the continuous roll film bag 100 before sealing and cutting. When packaging small items with large volume or items with cushioning fillers, the air inside the continuous roll film bag 100 can be quickly discharged through the reserved air holes, avoiding the problem of bulging and failure to seal during sealing, and ensuring smooth packaging without material jamming throughout the entire process.

[0062] This embodiment is a preferred embodiment, and the specific structure of the bag sealing mechanism 40 has been optimized.

[0063] In this embodiment, as Figures 2-4 As shown, the bag-supporting and sealing mechanism 40 includes a bag-supporting assembly 41 and a second heat-sealing assembly 42. The bag-supporting assembly 41 and the second heat-sealing assembly 42 are arranged sequentially below the bag-out mechanism 30 along the conveying direction of the continuous roll film bag 100. The bag support assembly 41 includes a first support rod 411, a second support rod 412, a third drive motor 413, and a fourth drive motor 414. The first support rod 411 and the second support rod 412 are arranged horizontally on both sides of the continuous roll film bag 100. The third drive motor 413 is connected to the first support rod 411 to drive the first support rod 411 to rotate longitudinally. The fourth drive motor 414 is connected to the second support rod 412 to drive the second support rod 412 to rotate longitudinally. The second heat-sealing assembly 42 includes a second pressing module 421, a second heat-sealing module 422, and a second driving assembly 423. The second pressing module 421 and the second heat-sealing module 422 are arranged in parallel. The second heat-sealing module 422 is installed below the bag support assembly 41. The second pressing module 421 is connected to the second driving assembly 423 through a connecting rod assembly 424. Under the drive of the second driving assembly 423, the second pressing module 421 moves closer to or further away from the second heat-sealing module 422.

[0064] Preferably, the bag support assembly 41 may further include a blower, which, together with the first support rod 411 and the second support rod 412, opens the bag opening of the continuous roll film bag 100 to facilitate feeding.
