Description

Technical Field

[0001] This invention relates to the field of optical communication module technology, specifically to a small-volume, high-speed packaging machine and packaging method. Background Technology

[0002] An optical communication module is a ubiquitous and crucial core component in modern communication networks. Simply put, an optical communication module is an interface device that performs photoelectric conversion. Its core functions are: at the transmitting end, it converts electrical signals generated by network devices (such as switches and routers) into optical signals and transmits them over long distances at high speeds via optical fiber. At the receiving end, it receives optical signals from the optical fiber, converts them back into electrical signals, and transmits them to network devices for processing.

[0003] As a high-precision device, optical communication modules require outer packaging during transportation and storage. With the deepening of Industry 4.0 and intelligent manufacturing, the outer packaging machines for optical communication modules are also paying more attention to the deep integration of intelligence and automation.

[0004] However, existing optical communication module outer box packaging machines mostly adopt a production line method to realize functions such as encoding and identification of optical communication modules, coding of packaging bags, and sealing bags. That is, each working point is set up sequentially according to the order of outer box packaging. Since the outer box packaging of optical communication modules involves multiple processes, this results in the entire outer box packaging machine production line being too long, occupying too much space, and having low packaging efficiency. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by the present invention is: how to provide a compact, small-area packaging machine and packaging method that can effectively shorten the distance between each working point, thereby achieving rapid bag sealing and improving packaging efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution: A small-volume, high-speed packaging machine includes a frame, on which are provided: The feeding mechanism includes a first feeding module and a second feeding module; A bagging mechanism is located between the first feeding module and the second feeding module. The bagging mechanism includes a bag opening module and a stacking and conveying module. The first feeding module and the second feeding module move in the axial direction and alternately convey the first material and the second material to the stacking and conveying module. The stacking and conveying module moves in the longitudinal direction and conveys the material to the bag opening module. The bag opening module fills the material into a bag. A bag sealing mechanism is used to vacuum and heat-seal a bag containing materials.

[0007] Thus, the first feeding module of the packaging machine of the present invention is used for feeding and conveying the first material, and the second feeding module is used for feeding and conveying the second material. The bagging mechanism is set between the first feeding module and the second feeding module. The first feeding module and the second feeding module alternately convey the first material and the second material to the stacking and conveying module in the axial direction. This can effectively reduce the movement distance of the first feeding module and the second feeding module, resulting in higher material feeding efficiency and a more compact overall structure. At the same time, the alternating feeding method allows the second feeding module to release material to the stacking and conveying module while the first feeding module is picking up material. This can make full use of the picking time of one feeding module to feed the other feeding module, thereby greatly improving the overall material feeding efficiency. In addition, the stacking conveyor module moves longitudinally and transports the material to the bag opening module for bagging. Designing the stacking conveyor module to move longitudinally makes full use of the longitudinal space of the entire structure. Through the rational use of the axial and longitudinal space of the entire structure, and the optimized design of the running direction of each feeding module in the feeding mechanism, the structure of the entire packaging machine can be made more compact and occupy less area. At the same time, by effectively shortening the distance between each working point, rapid bag sealing can be achieved, effectively improving packaging efficiency.

[0008] Preferably, the first feeding module and the second feeding module are arranged along the axial direction on one side of the frame, and the sealing mechanism and the bagging mechanism are arranged along the axial direction on the other side of the frame, and the bag containing the material moves from the bagging mechanism to the sealing mechanism along the axial direction.

[0009] In this way, the first and second feeding modules are set on one side of the frame, and the sealing and bagging mechanisms are set on the other side of the frame. The material transfer between the feeding and bagging mechanisms is realized by the longitudinal movement of the stacking and conveying module. This overall structural design conforms to the material packaging operation process and makes reasonable use of the longitudinal and axial space, which not only effectively improves the packaging efficiency of the packaging machine, but also greatly reduces the overall structural size of the packaging machine.

[0010] Preferably, the frame is further provided with: The bag feeding mechanism and the bag sealing mechanism are respectively arranged on both sides of the axial direction of the bag filling mechanism. The bag feeding mechanism includes a bag feeding module and a bag stacking module. Multiple bags are placed on the bag stacking module, and the bag feeding module sequentially picks up the bags from the bag stacking module. The belt conveyor mechanism transports the acquired bags from the upper bag module to the belt conveyor mechanism. The belt conveyor mechanism operates between the bagging mechanism and the sealing mechanism, and sequentially transports the bags to the bagging mechanism and the sealing mechanism for opening, filling, and sealing.

[0011] In this way, material bags are placed on the stacking module, and the bag loading module sequentially retrieves the material bags from the stacking module. The material bags are then conveyed to the belt conveyor mechanism, which moves and transports the material bags to the bag filling mechanism for material loading. After the material is loaded, the material bags are further conveyed by the belt conveyor mechanism to the bag sealing mechanism for vacuuming and sealing. This completes the material packaging process and realizes the automation of the entire bag loading, bag filling and bag sealing process.

[0012] Preferably, the first feeding module includes a stacking box assembly and a picking box assembly arranged vertically. The stacking box assembly has multiple boxes stacked vertically. The picking box assembly includes a box gripping component, a box axial linear motion component, and a box vertical linear motion component. The box axial linear motion component drives the box gripping component to move axially, and the box vertical linear motion component drives the box gripping component to move vertically. Driven by the box axial linear motion component and the box vertical linear motion component, the box gripping component sequentially picks up boxes from the stacking box assembly and transports the boxes to the stacking and conveying module.

[0013] In this way, multiple boxes are stacked vertically on the stacking box assembly. Then, the vertical linear motion component of the boxes drives the box gripping component to move vertically downward to the position corresponding to the box on the stacking box assembly. At this time, the box gripping component grabs the box. Then, the vertical linear motion component of the boxes drives the box gripping component to move vertically upward. When it moves upward to a certain position, the axial linear motion component of the boxes drives the box gripping component to move axially to the stacking and conveying module. Finally, the vertical linear motion component of the boxes drives the box gripping component to move vertically downward to place the box on the stacking and conveying module. After the box conveying is completed, the vertical linear motion component of the boxes and the axial linear motion component of the boxes drive the box gripping component to reset so that the next box conveying can be carried out.

[0014] Preferably, the second feeding module includes a stacking cover assembly and a picking cover assembly arranged vertically. The stacking cover assembly has multiple covers stacked vertically. The picking cover assembly includes a cover gripping component, a cover axial linear motion component, and a cover vertical linear motion component. The cover axial linear motion component drives the cover gripping component to move axially, and the cover vertical linear motion component drives the cover gripping component to move vertically. Driven by the cover axial linear motion component and the cover vertical linear motion component, the cover gripping component sequentially picks up the material boxes from the stacking cover assembly and transports the covers to the stacking transfer module.

[0015] In this way, multiple covers are stacked vertically on the stacking cover assembly. Then, the vertical linear motion component of the cover drives the cover gripping component to move vertically downward to the position corresponding to the cover on the stacking cover assembly. At this time, the cover gripping component grabs the cover. Then, the vertical linear motion component of the cover drives the cover gripping component to move vertically upward. When it moves upward to a certain position, the axial linear motion component of the cover drives the cover gripping component to move axially to the stacking transfer module. Finally, the vertical linear motion component of the cover drives the cover gripping component to move vertically downward to place the cover on the stacking transfer module. After the cover is transported, the vertical linear motion component of the cover and the axial linear motion component of the cover drive the cover gripping component to reset so that the next cover can be transported.

[0016] Preferably, the upper bag module includes a bag gripping component, a bag axial linear motion component, and a bag vertical linear motion component. The bag axial linear motion component drives the bag gripping component to move axially, and the bag vertical linear motion component drives the bag gripping component to move vertically. Driven by the bag axial linear motion component and the bag vertical linear motion component, the bag gripping component sequentially grips bags from the stacking module and conveys the bags to the belt conveyor mechanism.

[0017] In this way, when the upper bag module picks up a bag from the stacking bag module, the bag axial linear motion component first drives the bag gripping component to move axially to directly above the stacking bag module. Then, the bag vertical linear motion component drives the bag gripping component to move vertically downward and grip the bag. After gripping, the bag vertical linear motion component further drives the bag gripping component to move vertically upward. When it moves upward to a certain position, the bag axial linear motion component drives the bag gripping component to move axially to a set position. Then, the bag vertical linear motion component drives the bag gripping component to move vertically downward. When it moves downward to the set position, the bag gripping component places the bag on the belt conveyor mechanism. The bag gripping component is then reset by the bag axial linear motion component and the bag vertical linear motion component, waiting for the next bag delivery.

[0018] Preferably, the stacking and conveying module includes a material placement plate and a material longitudinal linear motion component. The material placement plate is used to place the first material conveyed by the first feeding module and the second material conveyed by the second feeding module. The material longitudinal linear motion component is used to drive the material placement plate to move longitudinally.

[0019] In this way, the first material conveyed by the first feeding module and the second material conveyed by the second feeding module are placed on the material placement plate. Then, the longitudinal linear motion component of the material drives the material placement plate to move longitudinally to convey the material to the bag opening module for bagging.

[0020] Preferably, the bag opening module includes a bag opening component, a material separation component, and a material conveying component. The bag opening component is used to open the bag conveyed by the belt conveyor mechanism. The material separation component is used to separate the material conveyed by the stacking conveyor module from the stacking conveyor module. The material conveying component is used to convey the separated material into the opened bag.

[0021] In this way, when the bag opening module is bagging materials, the material separation component first separates the material conveyed by the stacking and conveying module from the stacking and conveying module. Then, the material conveying component conveys the material to the corresponding position of the bag opening component. The bag opening component opens the bag conveyed by the belt conveyor mechanism. Then, the material conveying component continues to convey the material into the opened bag, thus completing the bagging process.

[0022] Preferably, the bag sealing mechanism includes a vacuuming component and a heat sealing component. The vacuuming component is used to vacuum the bag containing the material, and the heat sealing component is used to heat seal the bag after vacuuming.

[0023] In this way, when the belt conveyor transports the bagged material to the sealing mechanism, the vacuuming component first vacuums the bag, and then the heat sealing component further heat seals the vacuumed bag, completing the entire packaging process of the material.

[0024] A packaging method for a small-volume rapid packaging machine as described above, wherein the first feeding module and the second feeding module alternately convey the first material and the second material to the stacking and conveying module; The stacking and conveying module moves longitudinally and conveys the material to the bag opening module, which then loads the material into the bag. The sealing mechanism vacuums and heat-seals the bags containing materials. Attached Figure Description

[0030] To address the issues of large footprint and low packaging efficiency in existing packaging machines, this specific embodiment provides a small-volume, high-speed packaging machine, as shown in the attached figure. Figure 1 To the attached Figure 3 As shown, it includes a frame 1, on which a feeding mechanism, a bagging mechanism, a bag feeding mechanism, a belt conveyor mechanism 7, and a bag sealing mechanism 6 are provided.

[0031] The feeding mechanism includes a first feeding module 2 and a second feeding module 3, which are arranged along the axial direction on one side of the frame 1.

[0032] The bagging mechanism is located between the first feeding module 2 and the second feeding module 3. The bagging mechanism includes a bag opening module 8 and a stacking and conveying module 4. The first feeding module 2 and the second feeding module 3 move in the axial direction and alternately convey the first material and the second material to the stacking and conveying module 4. The stacking and conveying module 4 moves in the longitudinal direction and conveys the material to the bag opening module 8. The bag opening module 8 fills the material into the bag.

[0033] The sealing mechanism 6 is used to vacuum and heat seal the material bag. The sealing mechanism 6 and the bagging mechanism are arranged along the axial direction on the other side of the frame 1, and the material bag is moved from the bagging mechanism to the sealing mechanism 6 along the axial direction.

[0034] The bag loading mechanism and the bag sealing mechanism 6 are respectively arranged on both sides of the axial direction of the bag loading mechanism. The belt conveyor mechanism 7 runs between the bag loading mechanism and the bag sealing mechanism 6. The belt conveyor mechanism 7 sequentially transports the bags to the bag loading mechanism and the bag sealing mechanism 6 for opening, filling and sealing.

[0035] Thus, the first feeding module 2 of the packaging machine of the present invention is used for feeding and conveying the first material (a material box in this specific embodiment), and the second feeding module 3 is used for feeding and conveying the second material (a material cover in this specific embodiment). The bagging mechanism is set between the first feeding module 2 and the second feeding module 3. The first feeding module 2 and the second feeding module 3 alternately convey the first material and the second material to the stacking and conveying module 4 in the axial direction. This can effectively reduce the movement distance of the first feeding module 2 and the second feeding module 3, resulting in higher material feeding efficiency and a more compact overall structure. At the same time, the alternating feeding method allows the second feeding module 3 to release material to the stacking and conveying module 4 while the first feeding module 2 is taking material. This can make full use of the material taking time of one feeding module to feed the other feeding module, thereby greatly improving the overall material feeding efficiency.

[0036] In addition, the stacking conveyor module 4 moves in the longitudinal direction and transports the material to the bag opening module 8 for bagging. The stacking conveyor module 4 is designed to move in the longitudinal direction, which can make full use of the longitudinal space of the entire structure. Thus, through the rational use of the axial and longitudinal space of the entire structure, and the optimized design of the running direction of each feeding module in the feeding mechanism, the structure of the entire packaging machine can be made more compact and the footprint smaller. At the same time, by effectively shortening the distance between each working point, rapid bag sealing can be achieved, effectively improving packaging efficiency.

[0037] In addition, the first feeding module 2 and the second feeding module 3 are set on one side of the frame 1, and the sealing mechanism 6 and the bagging mechanism are set on the other side of the frame 1. The material transfer between the feeding mechanism and the bagging mechanism is realized by the longitudinal movement of the stacking transfer module 4. This overall structural design conforms to the material packaging operation process and makes reasonable use of the longitudinal and axial space, which effectively improves the packaging efficiency of the packaging machine and greatly reduces the overall structural size of the packaging machine.

[0038] The specific structure of each institution is explained in detail below: In this specific embodiment, as shown in the appendix Figure 4 and attached Figure 5 As shown, the first feeding module 2 includes a stacking box assembly and a picking box assembly arranged vertically. Multiple boxes 203 are stacked vertically on the stacking box assembly. The stacking box assembly includes a box placement plate 201. A box positioning plate 202 is provided on the box placement plate 201. The box positioning plate 202 is adapted to the shape of the box. The box positioning plate 202 can ensure the correct placement of the box. In specific production practice, the box positioning plate 202 can also be designed as a structure with adjustable size to accommodate more boxes of different sizes.

[0039] The material box assembly includes a material box gripping component, a material box axial linear motion component 205, and a material box vertical linear motion component 204. The material box axial linear motion component 205 is used to drive the material box gripping component to move linearly along the axial direction, and the material box vertical linear motion component 204 is used to drive the material box gripping component to move linearly along the vertical direction. Driven by the material box axial linear motion component 205 and the material box vertical linear motion component 204, the material box gripping component sequentially grips the material boxes from the stacking box assembly and transports the material boxes to the stacking transfer module 4. The axial linear motion component 205 and the vertical linear motion component 204 of the material box respectively realize linear motion in the axial and vertical directions. This linear motion can be achieved by using a linear motor and linear guide rail structure, or a cylinder, slider and guide rail structure, etc. These structures for realizing linear motion are all existing technologies. For those skilled in the art, the specific structure can be selected according to the actual design needs. Moreover, the implementation of this linear structure will not have a substantial impact on the solution of the present invention and is not a technical solution that needs to be protected by the present invention. Therefore, it will not be discussed in detail in the present invention.

[0040] Specifically, the hopper gripping component includes a hopper gripping mounting plate 206, a hopper gripper, a hopper gripping sensor 207, and a gripper drive unit 208. Both the hopper gripping sensor 207 and the gripper drive unit 208 are connected to the hopper gripping mounting plate 206. The contact of the hopper gripping sensor 207 faces the hopper assembly. The gripper drive unit 208 has two drive output ends that move in opposite axial directions. Each drive output end is connected to a hopper gripper. The gripper drive unit 208 drives the two hopper grippers to move closer together to grip the hopper or move away from each other to release the hopper through the two drive output ends. In this specific embodiment, the gripper drive unit 208 is implemented using a cylinder with two power output ends; however, other power structures can also be used in actual production practice.

[0041] The hopper gripper includes a hopper gripping part 210 and a hopper connecting part 209. The hopper connecting part 209 includes a first connecting plate and a second connecting plate. The first connecting plate is connected to the drive output end of the gripper drive 208, and the second connecting plate is connected to the hopper gripping part 210. The first connecting plate is provided with a first connecting hole, and the second connecting plate is provided with a plurality of second connecting holes along the axial direction. The first connecting hole can correspond to the second connecting holes at different positions and be fixedly connected by connecting fasteners.

[0042] The specific working method of the first feeding module is as follows: multiple boxes 203 are stacked vertically on the stacking box assembly. Then, the vertical linear motion component 204 drives the box gripping part 210 to move vertically downward to the position corresponding to the box on the stacking box assembly. At this time, the box gripping sensor 207 is triggered. At this time, the two driving ends of the gripper drive component 208 simultaneously drive the two box grippers to move closer to each other to grip the box. After gripping the box, the vertical linear motion component 204 drives the box gripping part 210 to move vertically upward. When it moves upward to a certain position, the axial linear motion component 205 drives the box gripping part 210 to move vertically upward. The material box gripping component moves axially to the stacking and conveying module 4. Finally, the material box vertical linear motion component 204 drives the material box gripping component to move vertically downward. When the material box is delivered to the stacking and conveying module 4 and needs to be placed, the two drive ends of the gripper drive component 208 simultaneously drive the two material box grippers to move away from each other to release the material box, so that the material box is placed on the stacking and conveying module 4, thus completing the gripping and placement of the material box. After the material box is placed on the stacking and conveying module 4, the material box vertical linear motion component 204 and the material box axial linear motion component 205 drive the material box gripping component 210 to reset, so as to carry out the next material box conveying.

[0043] In actual production practice, since there are various sizes of material boxes, a material box connecting part 209 is set up to adapt to the gripping of different material boxes. The material box connecting part 209 includes a first connecting plate and a second connecting plate. By using the second connecting holes at different positions on the second connecting plate to connect with the first connecting holes on the first connecting plate, the axial dimension of the entire material box connecting part 209 can be adjusted, thereby adapting to the gripping of material boxes with different axial dimensions and improving the versatility of the equipment.

[0044] In this specific embodiment, as shown in the appendix Figure 6 and attached Figure 7 As shown, the second feeding module 3 includes a stacking cover assembly and a picking cover assembly arranged vertically. The stacking cover assembly has multiple material covers stacked vertically. The stacking cover assembly includes a material cover placement plate 301. The material cover placement plate 301 is provided with a material cover positioning rod 302 and a material cover stacking anti-misalignment plate 303. The shape of the material cover stacking anti-misalignment plate 303 is adapted to the shape of the corresponding position of the material cover. By setting the material cover positioning rod 302, the placement position of the material cover can be positioned. At the same time, the material cover stacking anti-misalignment plate 303 is used to ensure the correctness of the placement direction of the material cover. Through the combined action of the material cover positioning rod 302 and the material cover stacking anti-misalignment plate 303, the correctness of the position of the material cover on the material cover placement plate 301 is ensured.

[0045] A blocking component is also provided on the material cover placement plate 301. The blocking component includes a blocking mounting plate 304, on which a blocking drive component 305 is mounted. In this specific embodiment, the blocking drive component 305 is a cylinder. The power output end of the blocking drive component 305 faces the material cover placement direction, and the power output end of the blocking drive component 305 can extend towards the material cover to apply force to the material cover. Specifically, there are two blocking components, which are symmetrically arranged on both sides of the material cover placement plate 301. The material cover is located between the two blocking components, and the power output ends of the blocking drive components 305 in both blocking components can extend simultaneously to apply force to the material cover.

[0046] In addition, to accommodate material covers of different sizes, multiple sets of blocking positioning posts 306 are provided on the material cover placement plate 301 at positions corresponding to each blocking mounting plate 304. The multiple sets of blocking positioning posts 306 are sequentially arranged towards the outer side of the material cover placement plate 301. The blocking mounting plate 304 is provided with blocking positioning grooves, which can cooperate with the blocking positioning posts 306 at different positions. Through the cooperation of the blocking positioning grooves on the blocking mounting plate 304 with the blocking positioning posts 306 at different positions, it can be adapted to material covers of different sizes, improving versatility.

[0047] The material grabbing cover assembly includes a material cover gripping component, a material cover axial linear motion component 308, and a material cover vertical linear motion component 307. The material cover axial linear motion component 308 is used to drive the material cover gripping component to move in an axial linear motion, and the material cover vertical linear motion component 307 is used to drive the material cover gripping component to move in a vertical linear motion. Driven by the material cover axial linear motion component 308 and the material cover vertical linear motion component 307, the material cover gripping component sequentially grabs the material box from the stacking cover assembly and transports the material cover to the stacking transfer module 4. The axial linear motion component 308 and the vertical linear motion component 307 of the material cover respectively realize linear motion in the axial and vertical directions. This linear motion can be achieved by adopting a linear motor plus linear guide rail structure, or a cylinder, slider plus guide rail, etc. These structural forms for realizing linear motion are all existing technologies. For those skilled in the art, the specific structure can be selected according to the actual design needs. Moreover, the implementation form of this linear structure will not have a substantial impact on the solution of the present invention and is not a technical solution that needs to be protected by the present invention. Therefore, it will not be discussed in detail in the present invention.

[0048] Specifically, the material cover gripping component includes a material cover gripping mounting plate 309. A material cover contact sensor 311 and multiple material cover spring suction nozzles 310 are mounted on the material cover gripping mounting plate 309. The contact end of the material cover contact sensor 311 faces the material cover direction. The multiple material cover spring suction nozzles 310 are divided into two groups and arranged on both sides of the width direction of the material cover gripping mounting plate 309. The multiple material cover spring suction nozzles 310 in the same group are arranged sequentially along the length direction of the material cover gripping mounting plate 309. The length of the contact end of the material cover contact sensor 311 extending out of the material cover gripping mounting plate 309 is less than the length of the corresponding side of the material cover spring suction nozzle 310 extending out of the material cover gripping mounting plate 309 in the free state, so that the material cover spring suction nozzle 310 makes contact with the material cover with priority from the contact end of the material cover contact sensor 311.

[0049] The second feeding module works as follows: multiple material covers are stacked vertically on the material cover assembly. Then, the material cover vertical linear motion component 307 drives the material cover gripping component to move vertically downward to the position corresponding to the material cover on the material cover assembly. At this time, the material cover gripping component grips the material cover. When gripping the material cover, the elasticity of the material cover spring suction nozzle 310 is used to adapt to the unevenness of the material cover surface. The contact sensor is used to detect whether the material cover spring suction nozzle 310 is in contact with the material cover, ensuring the reliability of material cover picking. The material cover spring suction nozzle 310 first contacts the material cover with the contact end of the material cover contact sensor 311. Only after there is a certain suction force between the material cover spring suction nozzle 310 and the material cover is the material cover contact sensor 311 triggered, ensuring that the material cover spring suction nozzle 310 has sufficient suction force on the material cover, further improving the reliability of material cover picking. Meanwhile, the distribution of multiple cap spring suction nozzles 310 allows for multiple contact points between the cap spring suction nozzles 310 and the caps, further ensuring the reliability of cap suction. Since the caps are stacked layer by layer, when the cap gripping component picks up the upper cap, the lower cap may be pulled out due to jamming. Therefore, a blocking component is provided. When the cap gripping component picks up the upper cap to a certain height, the power output end of the blocking drive 305 extends towards the cap, blocking the lower cap and preventing it from being pulled out along with the upper one. By setting two blocking components, when the cap gripping component picks up the upper cap to a certain height, the power output ends of both blocking drive components 305 simultaneously extend towards the cap to apply force to the lower cap, blocking it. The simultaneous action in two directions ensures the blocking effect on the lower cap.

[0050] After the cover is picked up, the cover vertical linear motion component 307 drives the cover gripping component to move vertically upward. When it moves to a certain position, the cover axial linear motion component 308 drives the cover gripping component to move axially to the stacking and conveying module 4. Finally, the cover vertical linear motion component 307 drives the cover gripping component to move vertically downward, placing the cover on the cover gripping component onto the stacking and conveying module 4. After the cover is conveyed, the cover vertical linear motion component 307 and the cover axial linear motion component 308 drive the cover gripping component to reset, so that the cover can be conveyed again.

[0051] In this specific embodiment, as shown in the appendix Figure 8 To the attached Figure 9As shown, the bag feeding mechanism 5 includes a bag feeding module and a bag stacking module. Multiple bags are placed on the bag stacking module. The bag feeding module sequentially retrieves bags from the bag stacking module and transports the retrieved bags to the belt conveyor mechanism 7. Specifically, the bag stacking module includes a bag placement plate 501, on which multiple bag positioning adjustment plates 503 are provided. The bag positioning adjustment plates 503 are used to position the bags. A bag placement detection sensor 502 is also provided in the middle of the bag placement plate 501 to detect the status of the bags on the bag placement plate 501. The bag-loading module includes a bag-grabbing component, a bag-axial linear motion component, and a bag-vertical linear motion component. The bag-axial linear motion component drives the bag-grabbing component to move linearly along the axial direction, and the bag-vertical linear motion component drives the bag-grabbing component to move linearly along the vertical direction. Driven by these components, the bag-grabbing component sequentially grabs bags from the bag-stacking module and conveys them to the belt conveyor mechanism 7. The bag-axial linear motion component and the bag-vertical linear motion component respectively achieve linear motion in the axial and vertical directions. This linear motion can be achieved using a linear motor and linear guide rail structure, or a cylinder, slider, and guide rail structure, etc. These structural forms for achieving linear motion are all existing technologies. Those skilled in the art can choose the specific structure according to actual design needs. Moreover, the implementation of this linear structure does not substantially affect the solution of this invention and is not a technical solution that needs to be protected by this invention; therefore, it will not be discussed in detail in this invention.

[0052] Specifically, the bag gripping component includes a bag gripping mounting frame 504, on which a bag contact sensor 507 and multiple bag spring suction nozzles 505 are mounted. The contact end of the bag contact sensor 507 faces the bag direction. The multiple bag spring suction nozzles 505 are divided into two groups and arranged on both sides of the bag gripping mounting frame 504. The multiple bag spring suction nozzles 505 in the same group are arranged sequentially along the length of that side of the bag gripping mounting frame 504. The length of the contact end of the bag contact sensor 507 extending out of the bag gripping mounting frame 504 is less than the length of the corresponding side of the bag spring suction nozzle 505 extending out of the bag gripping mounting frame 504 in the free state, so that the bag spring suction nozzle 505 makes priority contact with the bag contact sensor 507.

[0053] For details, see attached. Figure 10As shown, the upper bag module also includes a clamping assembly, which includes a clamping drive 510 and clamping wheels 508. In this specific embodiment, the clamping drive 510 is a cylinder, and there are two clamping wheels 508. The clamping drive 510 is connected to the bag gripping mounting frame 504 via a clamping mounting plate 511. A clamping sensor 509 is provided on the clamping mounting plate 511. The power output end of the clamping drive 510 is connected to a clamping plate 513, so that the clamping plate 513 can be driven by the power output end of the clamping drive 510. Moving vertically, a clamping spring 512 is provided between the clamping mounting plate 511 and the clamping plate 513. The two ends of the clamping spring 512 are connected to the clamping mounting plate 511 and the clamping plate 513 respectively. A clamping signal block 514 is also provided on the clamping plate 513. The contact end of the clamping signal block 514 and the clamping sensor 509 can contact or separate. The clamping wheel 508 is mounted on the clamping plate 513 so that the clamping plate 513 can drive the clamping wheel 508 to move vertically and press the bag onto the belt transmission mechanism 7.

[0054] The working process of the bag loading mechanism is as follows: the bag is placed on the bag stacking module, the bag loading module sequentially picks up the bag 506 from the bag stacking module, and then the bag is transported to the belt conveyor mechanism 7. When the upper bag module picks up a bag from the stacking bag module, the axial linear motion component of the bag first drives the bag gripping component to move axially to directly above the stacking bag module. Then, the vertical linear motion component of the bag drives the bag gripping component to move vertically downward and grip the bag. By setting a bag contact sensor 507 and a bag spring suction nozzle 505 on the bag gripping mounting frame 504, when the vertical linear motion component of the bag drives the bag gripping component to move vertically downward to a certain position, the bag spring suction nozzle 505 contacts the bag and generates a certain pre-pressure. At this time, the bag contact sensor 507 is triggered, indicating that the bag has been reliably picked up. In actual use, the bag spring suction nozzle 505 prioritizes contacting the bag with the contact end of the bag contact sensor 507, so that there is a certain suction force between the bag spring suction nozzle 505 and the bag before the bag contact sensor 507 is triggered. This ensures that the bag spring suction nozzle 505 has sufficient suction force on the bag, further improving the reliability of bag picking. After the bag is picked up, the vertical linear motion component of the bag drives the bag gripping component to move vertically upward. When it moves to a certain position, the axial linear motion component of the bag drives the bag gripping component to move axially to a set position. Then, the vertical linear motion component of the bag drives the bag gripping component to move vertically downward. When it moves downward to a set position, the bag gripping component places the bag onto the belt conveyor 7. The bag gripping component is then reset by the axial linear motion component and the vertical linear motion component of the bag, until the next bag is conveyed.

[0055] Since the bags are generally large in size, placing all the bags on the belt conveyor mechanism 7 would undoubtedly increase the overall size of the packaging machine. Therefore, in this solution, the bag-raising module only places a portion of the bag on the belt conveyor mechanism 7, and a clamping component is used to ensure that the entire bag is reliably and completely transported to the belt conveyor mechanism 7. Specifically, when the bag spring suction nozzle 505 places a portion of the bag onto the belt conveyor mechanism 7, the vacuum of the bag spring suction nozzle 505 is released. After the bag spring suction nozzle 505 separates from the bag by a certain distance, the power output end of the clamping drive 510 moves vertically downward. At this time, the clamping plate 513 and the clamping wheel 508 follow the power output end of the clamping drive 510 and move vertically downward. The clamping wheel 508 presses the bag onto the belt conveyor mechanism 7 as it moves vertically downward. As the belt conveyor mechanism 7 operates, the bag is gradually and completely transported onto the belt conveyor mechanism 7, while the clamping wheel 508 ensures the stability of the bag transport throughout the process. This is because the clamping mounting plate 511 is connected to the bag gripping mounting frame 504. When the bag spring suction nozzle 505 places a portion of the bag onto the belt transmission mechanism 7, the bag vertical linear motion component will drive the bag gripping mounting frame 504 to move vertically upwards. Since the clamping sensor 509 is connected to the clamping mounting plate 511, and the clamping signal block 514 is connected to the clamping plate 513, the clamping sensor 509 will move upwards along with the clamping mounting plate 511, while the clamping signal block 514 will remain stationary. The pressure sensor 509 remains stationary until its contact end separates from the pressure signal block 514, triggering the pressure sensor 509. At this point, the bag spring suction nozzle 505 separates from the bag, and the bag vertical linear motion component stops driving the bag gripping mounting frame 504 upward. Simultaneously, the power output end of the pressure drive component 510 moves vertically downward, and the pressure plate 513 and pressure wheel 508 follow the power output end of the pressure drive component 510 to move vertically downward. The pressure wheel 508 moves vertically downward to press the bag onto the belt transmission mechanism 7.

[0056] In this specific embodiment, as shown in the appendix Figure 11As shown, the stacking and conveying module includes a material placement plate 402 and a material longitudinal linear motion component 401. The material placement plate 402 is used to place the first material conveyed by the first feeding module 2 and the second material conveyed by the second feeding module 3. The material longitudinal linear motion component 401 is used to drive the material placement plate 402 to move longitudinally. A material positioning block 403 and a material clamping drive 404 are also provided on the material placement plate 402. Material is placed between the material positioning block 403 and the material clamping drive 404. One side of the material abuts against the material positioning block 403, and the other side of the material has a gap with the material clamping drive 404. The power output end of the material clamping drive 404 can move in the direction of the material and abut against the material at the corresponding position. The longitudinal linear motion component 401 realizes linear motion in the longitudinal direction. This linear motion can be achieved by using a linear motor and linear guide rail structure, or a cylinder, slider and guide rail structure, etc. These structures for realizing linear motion are all existing technologies. For those skilled in the art, the specific structure can be selected according to the actual design needs. Moreover, the implementation of this linear structure will not have a substantial impact on the solution of the present invention and is not a technical solution that needs to be protected by the present invention. Therefore, it will not be discussed in detail in the present invention.

[0057] The stacking and conveying module operates as follows: the first feeding module 2 places the first material being conveyed and the second feeding module 3 placing the second material being conveyed onto the material placement plate 402. Then, the longitudinal linear motion component 401 drives the material placement plate 402 to move longitudinally, conveying the material to the bag opening module 8 for bagging. By setting the material positioning block 403 and the material clamping drive 404, when the bottom layer of material is placed on the material placement plate 402, in order to ensure the accuracy of the material position, the power output end of the material clamping drive 404 moves in the direction of the material and applies a force to the material, so that both ends of the material abut against the material positioning block 403 and the power output end of the material clamping drive 404, respectively. This limits the two ends of the material to ensure the accuracy of the material placement position.

[0058] In this specific embodiment, as shown in the appendix Figure 12 To the attached Figure 14As shown, the bag opening module 8 includes a bag opening component, a material separation component, a material conveying component, and a bag opening longitudinal linear motion component 807. The bag opening component is used to open the bag conveyed by the belt conveyor mechanism 7. The material separation component is used to separate the material conveyed by the stacking conveyor module 4 from the stacking conveyor module 4. The material conveying component is used to convey the separated material into the opened bag. The fixing part of the bag opening longitudinal linear motion component 807 is installed on the frame 1. The moving part of the bag opening longitudinal linear motion component 807 is connected to both the material separation component and the bag tensioning component, so that the moving part of the bag opening longitudinal linear motion component 807 can drive the material separation component and the bag tensioning component to move longitudinally. In this way, when the bag opening module 8 is bagging materials, the material separation component first separates the material conveyed by the stacking and conveying module 4 from the stacking and conveying module 4. Then, the material conveying component conveys the material to the corresponding position of the bag opening component. The bag opening component opens the bag conveyed by the belt conveyor mechanism 7, and then the material conveying component continues to convey the material into the opened bag, thus completing the bagging process. In specific operation, when the bag is conveyed from the belt conveyor mechanism 7 to the bag opening module 8, the bag opening longitudinal linear motion component 807 first drives the bag tensioning component to move longitudinally away from the belt conveyor mechanism 7, thereby making room for the bag to be conveyed. When the bag is in place, the bag opening longitudinal linear motion component 807 drives the bag opening tensioning component to move closer to the belt conveyor mechanism 7 and opens the bag. The longitudinal linear motion component 807 for opening the bag achieves linear motion in the longitudinal direction. This linear motion can be achieved by using a linear motor and linear guide rail structure, or a cylinder, slider and guide rail structure, etc. These structural forms for achieving linear motion are all existing technologies. For those skilled in the art, the specific structure can be selected according to actual design needs. Moreover, the implementation form of this linear structure does not have a substantial impact on the solution of the present invention and is not a technical solution that needs to be protected by the present invention. Therefore, it will not be discussed in detail in the present invention.

[0059] Specifically, the material on the material placement plate 402 protrudes from the corresponding positions of the material placement plate 402 at both ends in the axial direction. The material separation assembly includes two material separation components symmetrically distributed on both sides of the material longitudinal linear motion assembly 401. The material separation component includes a material separation drive 801, a longitudinal guide plate 803, and a longitudinal guide rod 802. When the material moves along the material longitudinal linear motion assembly 401, the longitudinal guide rod 802 can extend into the bottom of the material at the corresponding position. The power output end of the material separation drive 801 is connected to both the longitudinal guide plate 803 and the longitudinal guide rod 802 through a separation connector, so that the material separation drive 801 can simultaneously drive the longitudinal guide plate 803 and the longitudinal guide rod 802 to move vertically, and the axial distance between the two longitudinal guide plates 803 is adapted to the axial dimension of the material. In this specific embodiment, the material separation drive 801 is a cylinder. The material conveying assembly includes a longitudinal material conveying power component 804 and a vertical material conveying power component 805. The fixed end of the longitudinal material conveying power component 804 is connected to the frame 1, and the power output end of the longitudinal material conveying power component 804 is connected to the fixed end of the vertical material conveying power component 805. The power output end of the vertical material conveying power component 805 can move vertically and abut against the material at the material separation component, so that the longitudinal material conveying power component 804 can drive the material to move longitudinally through the vertical material conveying power component 805. In this specific embodiment, the longitudinal material conveying power component 804 adopts a long-stroke longitudinal cylinder, and the vertical material conveying power component 805 adopts a vertical cylinder. The bag opening assembly includes a vacuum nozzle component and a bag tensioning component. The vacuum nozzle component includes multiple lower vacuum nozzles 809 located below the bag and multiple upper vacuum nozzles 811 located above the bag. The lower vacuum nozzles 809 are fixed on the nozzle mounting plate, and the upper vacuum nozzles 811 are fixed on the power output end of the nozzle drive component 810. The power output end of the nozzle drive component 810 can drive the upper vacuum nozzles 811 to move vertically and contact the bag. In this specific embodiment, the nozzle drive component 810 is a cylinder. The bag tensioning component includes two bag tensioning members 806 distributed along the axial direction. Each bag tensioning member 806 includes two bag tensioning rods distributed vertically with a set distance. Each bag tensioning member 806 is also provided with a bag tensioning drive member 808. The power output end of the bag tensioning drive member 808 is connected to the bag tensioning member 806 so as to drive the bag tensioning member 806 to move along the axial direction. In this specific embodiment, the bag tensioning drive member 808 is a cylinder.

[0060] The working process of the bag opening module 8 is as follows: When the material moves along the longitudinal linear motion component on the material placement plate 402 to the longitudinal guide rod 802, the longitudinal guide rod 802 extends into the bottom of the material after it protrudes from the material placement plate 402. When the material is conveyed to the position of the material separation drive 801, the longitudinal guide rod 802 has already covered the bottom of the material. At this time, the material separation drive 801 is activated. The power output end of the material separation drive 801 drives the longitudinal guide rod 802 and the longitudinal guide plate 803 to move upwards vertically in sync. Under the support of the longitudinal guide rod 802, the material moves upwards along with the longitudinal guide rod 802 and separates from the material placement plate 402, thereby conveying the material from the stacking and conveying component to the bag opening component. After the material is supported by the longitudinal guide rod 802 and separated from the stacking and conveying components, the power output end of the material vertical power unit 805 moves vertically downward and comes into contact with the material. Then, the material longitudinal conveying power unit 804 drives the material vertical power unit 805 together with the material to move longitudinally towards the bag. During the conveying process, the longitudinal guide plate 803 will guide the movement of the material to ensure that the material travels along the predetermined route.

[0061] In addition, before the bag is conveyed to the bag opening assembly, the bag opening longitudinal linear motion assembly 807 drives the bag tensioning component to move longitudinally away from the belt transmission mechanism. When the bag moves to the bag opening assembly along with the belt transmission mechanism 7, the lower vacuum nozzle 809 on the nozzle mounting plate is located below the bag, and the upper vacuum nozzle 811 on the power output end of the nozzle drive 810 will be located above the bag. The lower vacuum nozzle 809 located below the bag is fixed in position, tightly sucking the bottom of the bag, while the upper vacuum nozzle 811 above the bag can move up and down under the action of the nozzle drive 810. Therefore, the upper vacuum nozzle 811 can pull the upper part of the bag upward under the action of the nozzle drive 810, thereby opening the bag. After the bag is opened by the vacuum nozzle component, the longitudinal linear motion component 807 drives two bag tensioning members 806 to insert into the opened bag. Then, the bag tensioning drive component 808 drives the corresponding bag tensioning members 806 to move axially away from each other. Simultaneously, since each bag tensioning member 806 includes two vertically distributed bag tensioning rods with a set spacing, the entire bag is fully opened with a certain vertical opening, facilitating material entry. After the bag is further opened by the bag tensioning components, the longitudinal material conveying power component 804, through the vertical material power component 805, pushes the material into the bag, completing the bagging process.

[0062] In this specific embodiment, as shown in the appendix Figure 15 and attached Figure 16As shown, the bag sealing mechanism 6 includes a vacuuming component, a heat sealing component, and a bag sealing longitudinal linear motion component 601. The vacuuming component is used to vacuum the material-filled bag, and the heat sealing component is used to heat seal the vacuumed bag. Specifically, the heat sealing component includes a heat sealing knife 604 and a heat sealing power component 605. The heat sealing power component 605 is connected to the frame 1, and the power output end of the heat sealing power component 605 is connected to the heat sealing knife 604, so that the heat sealing knife 604 can be driven to move vertically and heat seal the bag. The moving part of the bag sealing longitudinal linear motion component 601 is connected to the vacuuming component, so that the vacuuming component can be driven to move longitudinally. By setting up a longitudinal linear motion component 601 for sealing bags, before the material-filled bag reaches the sealing mechanism 6, the longitudinal linear motion component 601 drives the vacuuming component to move away from the belt conveyor mechanism 7, making room for the bag to be conveyed. After the bag is conveyed to the correct position, the longitudinal linear motion component 601 drives the vacuuming component to move closer to the belt conveyor mechanism 7 to vacuum the bag. Then, the heat-sealing component further heat-seales the vacuumed bag, completing the entire packaging process. The longitudinal linear motion component 601 achieves linear motion in the longitudinal direction. This linear motion can be achieved using a linear motor and linear guide rail structure, or a cylinder, slider, and guide rail structure. These structural forms for achieving linear motion are all existing technologies. Those skilled in the art can choose the specific structure according to actual design needs. Moreover, the implementation of this linear structure does not substantially affect the solution of this invention and is not a technical solution that needs to be protected by this invention. Therefore, it will not be discussed in detail in this invention.

[0063] Specifically, the vacuum assembly includes a vacuum suction head 603, a suction head motion drive component 613, two bag-sealing support rods 608, and two bag-sealing clamping components. The vacuum suction head 603 can extend into the bag to perform vacuuming. The power output end of the suction head motion drive component 613 is connected to the vacuum suction head 603, so that the vacuum suction head 603 can be driven to move longitudinally through the suction head motion drive component 613. In this specific embodiment, the suction head driving component is a cylinder. Two sealing support rods 608 are located on opposite sides of the vacuum suction head 603, and the sealing support rods 608 can extend into the bag. Each sealing support rod 608 is also provided with a support rod drive member 612. The power output end of the support rod drive member 612 is connected to the sealing support rod 608, so that the sealing support rod 608 is driven to move axially to tighten the bag. The bag clamping component includes a sealing clamping plate 610, a clamping seat 611, and a sealing clamping drive member. 609, the sealing clamp plate 610 and the clamping seat 611 are arranged vertically, and there is a gap between the sealing clamp plate 610 and the clamping seat 611. The sealing support rod 608 can move the bag into the gap between the sealing clamp plate 610 and the clamping seat 611 under the drive of the support rod drive member 612. The power output end of the sealing clamp drive member 609 is connected to the sealing clamp plate 610 so as to drive the sealing clamp plate 610 to move vertically through the power output end of the sealing clamp drive member 609.

[0064] Specifically, the sealing mechanism 6 also includes a sealing and pressing plate 607 and a heat-sealing and bonding plate 602. The heat-sealing and bonding plate 602 is connected to the moving part of the sealing longitudinal linear motion assembly 601, and the heat-sealing and bonding plate 602 is used to place the material bag. A suction head clearance groove is provided on the sealing and pressing plate 607 at a position corresponding to the vacuum suction head 603. A sealing and pressing drive 606 is also provided on the sealing and pressing plate 607. The sealing and pressing drive 606 is connected to the frame 1, and the power output end of the sealing and pressing drive 606 is connected to the sealing and pressing plate 607 so that the sealing and pressing plate 607 can be driven to move vertically and press the material bag through the power output end of the sealing and pressing drive 606.

[0065] The working process of the sealing mechanism 6 is as follows: When the bag is conveyed to the sealing mechanism, the sealing longitudinal linear motion component 601 drives the vacuum component to move away from the belt conveyor mechanism 7 to make room for the bag. When the bag is conveyed to the sealing mechanism 6, the sealing longitudinal linear motion component 601 drives the vacuum component to move towards the bag. At this time, both sealing support rods 608 and the vacuum suction head 603 extend into the bag. After the sealing support rods 608 extend into the bag, the support rod drive component 612 drives the corresponding sealing support rods 608 to move away from the vacuum suction head 603 to tighten the bag and move the tightened bag into the gap between the sealing clamp and the clamping seat 611. At this time, the power output end of the sealing clamp drive component drives the bag to move away from the vacuum suction head 603. The dynamic sealing clamp moves vertically downward, further clamping the taut bag located between the sealing clamp and the clamping seat 611. By clamping both sides of the bag, the vacuum suction head 603 improves the vacuuming effect on the bag. Before vacuuming the bag, the longitudinal linear motion component 601 drives the heat sealing plate 602 to move below the sealing pressure plate 607, so that the bottom of the bag is located at the heat sealing plate 602. The heat sealing plate 602 provides support for the bottom of the bag during vacuuming and heat sealing. Before vacuuming, the power output end of the sealing and pressing drive 606 drives the sealing and pressing plate 607 to move vertically to the position where it presses against the bag. The suction head clearance groove on the sealing and pressing plate 607 corresponds to the position of the vacuum suction head 603 to ensure the normal operation of the vacuum suction head 603. At this time, except for the position of the vacuum suction head 603, the sealing and pressing plate 607 presses against the other parts of the bag. The vacuum suction head 603 performs vacuuming on the bag, which can ensure the vacuuming effect of the bag. When vacuuming the bag, the suction head movement drive 613 drives the vacuum suction head 603 to extend into the bag. After the vacuuming is completed, the suction head movement drive 613 drives the vacuum suction head 603 to exit the bag. At this time, the heat sealing drive 605 drives the heat sealing knife 604 to move vertically downward. When the heat sealing knife 604 contacts the bag, the heat sealing knife 604 heats up, melting and sealing the bag, thus completing the heat sealing process of the bag.

[0066] In this specific embodiment, the belt conveyor mechanism 7 includes a conveyor belt and a belt conveyor power assembly. The belt conveyor power assembly drives the conveyor belt to move, thereby conveying the bags. Simultaneously, a labeling machine 9 is provided between the bag-adding module and the bag-opening module 8. The labeling machine 9 is used to code the bags, ensuring that the bags delivered to the bag-opening module 8 are coded, facilitating product traceability.

[0067] In this embodiment, as shown in the appendix Figure 17As shown, the frame 1 is also equipped with a vision mechanism 10, which includes an upper vision module and a lower vision module. The upper vision module corresponds to the position of the first feeding module 2, and the lower vision module corresponds to the position of the stacking and conveying module 4. The upper vision module includes an upper camera 1001 and an upper longitudinal linear motion component 1002. The moving part of the upper longitudinal linear motion component 1002 is connected to the camera to drive the upper camera 1001 to move longitudinally. The lower vision module includes a lower camera 1003, a lower vertical linear motion component 1004, and a lower axial linear motion component 1005. The lower vertical linear motion component 1004 is used to drive the lower camera 1003 to move vertically, and the lower axial linear motion component 1005 is used to drive the lower camera 1003 to move axially.

[0068] Thus, by setting up the vision mechanism 10, the labels on the material boxes can be scanned, and the material boxes can also be inspected for flaws. Since some material boxes have labels at the bottom and some have labels at the top, both an upward vision module and a downward vision module are set up. When the label of the material box is at the bottom, the upward camera 1001 is used to scan the label. The upward longitudinal linear motion component 1002 can realize the longitudinal movement of the upward camera 1001, and the material box vertical linear motion component 204 and the material box axial linear motion component 205 can realize the relative axial and vertical positions between the material box and the upward camera 1001, thereby enabling the scanning of labels at different positions on the bottom of the material box. When the label on the material box is at the top, the downward-viewing camera 1003 scans the label. The downward-viewing axial linear motion component 1005 and the downward-viewing vertical linear motion component 1004 can realize the axial and vertical movement of the downward-viewing camera 1003. The longitudinal movement of the stacking and conveying component can realize the relative movement between the material box and the downward-viewing camera 1003 in the longitudinal direction. This allows scanning of different positions above the material box. At the same time, the relative movement of the downward-viewing camera 1003 and the upward-viewing camera 1001 with the material box in the vertical direction can also realize the flaw detection treatment of the surface of the material box.

[0069] The complete packaging method of this small-volume rapid packaging machine is as follows: The operator places the material bag containing the optical communication module on the material bag placement plate 501 of the stacking module, places the material box containing the optical communication module on the material box placement plate 201, and places the material cover on the material cover placement plate 301. Then, the first feeding module 2 and the second feeding module 3 alternately convey the first material and the second material to the material placement plate 402 of the stacking and conveying module 4. The stacking and conveying module 4 moves along the longitudinal direction of the material and conveys the material to the bag opening module 8. When the material moves along the longitudinal linear motion component on the material placement plate 402 to the longitudinal guide rod 802, the material separation component drives the material to separate from the stacking and conveying module 4. At this time, the power output end of the vertical power component 805 moves vertically downward and contacts the material. Then, the longitudinal conveying power component 804 drives the vertical power component 805 and the material together to move towards the material bag. On the other hand, the upper bag module picks up the material bag from the stacking bag module and conveys it to the conveyor belt of the belt conveyor mechanism 7. Before the material bag is conveyed to the bag opening component, the bag opening longitudinal linear motion component 807 drives the material bag tensioning component to move longitudinally away from the belt conveyor mechanism. When the material bag moves to the bag opening component with the belt conveyor mechanism 7, the vacuum suction component opens the material bag. After the material bag is opened by the vacuum suction component, the bag opening longitudinal linear motion component 807 drives the two material bag tensioning components 806 to insert into the opened material bag. Then, the material bag tensioning drive component 808 drives the corresponding material bag tensioning components 806 to move axially away from each other to open the material bag into a form with a certain height opening. At this time, the material longitudinal conveying power component 804 pushes the material into the material bag through the material vertical power component 805, completing the material bagging process and facilitating the material to enter the material bag. After the material is loaded into the bag, the belt conveyor 7 further transports the bag to the sealing mechanism. When the bag is transported to the sealing mechanism, the sealing longitudinal linear motion component 601 drives the vacuum component to move away from the belt conveyor 7 to make room for the bag.When the bag is conveyed to the sealing mechanism 6, the sealing longitudinal linear motion component 601 drives the vacuuming component to move towards the bag. At this time, both sealing support rods 608 and the vacuum suction head 603 extend into the bag. The support rod drive component 612 drives the corresponding sealing support rods 608 to move away from the vacuum suction head 603 to tighten the bag. The tightened bag is then moved into the gap between the sealing clamping plate and the clamping seat 611. The sealing clamping drive component further clamps the bag. At the same time, the sealing longitudinal linear motion component 601 drives the heat sealing and bonding plate 602 to move below the sealing and pressing plate 607, so that the bottom of the bag is located at the heat sealing and bonding plate. At plate 602, the power output end of the sealing and pressing drive 606 drives the sealing and pressing plate 607 to move vertically to the position of pressing with the bag. The suction head clearance groove on the sealing and pressing plate 607 corresponds to the position of the vacuum suction head 603, making room for the vacuum suction head 603. Then, the vacuum suction head 603 performs vacuum treatment on the bag. After the vacuum treatment of the bag is completed, the suction head movement drive 613 drives the vacuum suction head 603 to exit the bag. At this time, the heat sealing power component 605 drives the heat sealing knife 604 to move vertically downward. When the heat sealing knife 604 contacts the bag, the heat sealing knife 604 heats up, causing the bag to melt and seal, thus completing the heat sealing treatment of the bag. After the material separation component separates the material from the stacking and conveying component, the stacking and conveying component resets, and the bag opening module 8 performs bagging processing on the material. At this time, the first feeding module 2 and the second feeding module 3 can simultaneously feed the first and second materials. When the bag sealing mechanism 6 performs bag sealing processing, the bag opening module 8 can also simultaneously perform bagging processing on the material, thereby realizing synchronous operation of multiple stations and further improving the bag sealing efficiency of the packaging machine.
