Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment technology, and specifically relates to a bagging machine and bagging system. Background Technology

[0002] In the previous generation of bagging machines, the sealing mechanism, bag film feeding mechanism, film pulling mechanism, and bag supporting mechanism were highly integrated into the frame. This enabled an automated process of pulling out the bag film, opening the bag, loading the roll material, and sealing the bag. However, different users have different requirements for the sealing method of roll material packaging. For example, some users want the packaging to be sealed with tape, while others want it to be sealed with cable ties. However, because the sealing mechanism is highly integrated into the frame and closely connected to other mechanisms, it is difficult for users and manufacturers to adjust or replace the sealing mechanism. On the other hand, it would be too costly for manufacturers to design two integrated solutions for the two sealing methods.

[0003] Therefore, existing technologies need to be improved and developed. Utility Model Content

[0004] The purpose of this utility model is to provide a bagging machine and bagging system, which aims to solve the technical problem that existing integrated bagging machines have significant deficiencies in the flexibility and replaceability of the sealing mechanism, and cannot effectively meet the diversified needs of the market, thus significantly improving their adaptability and flexibility in different application scenarios.

[0005] In a first aspect, this utility model provides a bagging machine, including a bag film feeding mechanism, a film pulling mechanism, and a bag supporting mechanism sequentially arranged on a first frame. The film pulling mechanism is used to pull the bag film located at the front end of the bag film feeding mechanism to the bag supporting mechanism, and to open the bag film opening through the bag supporting mechanism so that the roll material can be loaded into the bag film through the bag film opening. It also includes a clamping mechanism and a sealing mechanism. The sealing mechanism is separately arranged outside the first frame and is used to close the bag film opening. The clamping mechanism is arranged between the sealing mechanism and the first frame and is used to transfer the roll material to be sealed placed on the first frame to the sealing mechanism.

[0006] Compared to solutions that integrate the sealing mechanism onto the first frame, the bagging machine provided by this utility model features a separately designed sealing mechanism. This allows users to more easily replace different sealing mechanisms, enabling them to adopt different sealing methods and adapt to various application scenarios. This effectively solves the problem that existing integrated bagging machines have significant shortcomings in terms of the flexibility and replaceability of the sealing mechanism, and thus cannot effectively meet the diverse needs of the market.

[0007] Furthermore, the sealing mechanism includes a second frame, on which a roller is provided. The roller is used to support the roll of material to be sealed and drive the roll of material to be sealed to rotate around its own axis.

[0008] The bag sealing mechanism also includes a sealing mechanism, which includes two folding parts arranged opposite to each other on the left and right sides of the roller, and an adhesive tape pasting part;

[0009] The folding section includes an upward control lever and a gathering control lever. The two upward control levers of the folding section extend in opposite directions in the left and right directions and interfere with the excess packaging film at the end of the roll to be sealed. The two upward control levers are used to control the excess packaging film to fold upward.

[0010] The gathering control lever is slidably mounted on the first slide rail in the left and right direction. The two gathering control levers can move closer to each other in the left and right direction through the corresponding first slide rail, so that the excess packaging film after being flipped up is gathered by the pressure of the two gathering control levers.

[0011] The folding part is slidably mounted on the second slide rail in the front-back direction. The two folding parts can move backward synchronously so that the excess packaging film material after being gathered is folded around the periphery of the roll material to be sealed by the obstruction of the two upward control levers.

[0012] The adhesive tape applicator is used in conjunction with the roller to apply and wrap the adhesive tape around the periphery of the roll of material to be sealed.

[0013] Furthermore, the sealing mechanism includes a third frame, on which a support base, a sealing claw mechanism, and a sealing machine are provided;

[0014] The support is used to fix the roll of material to be sealed.

[0015] The sealing claw mechanism is located at one end of the support seat along its length and is used to clamp the excess packaging film at the end of the roll to be sealed and to twist and gather the excess packaging film by rotation.

[0016] The tying machine is positioned between the support and the tying claw mechanism and is used to tie the cable ties to the excess packaging film.

[0017] Furthermore, the third frame is also equipped with a lifting device, which is connected to the tying claw mechanism and is used to drive the tying claw mechanism to reciprocate in the up and down direction.

[0018] Furthermore, the clamping claw mechanism is slidably mounted on the third slide rail and can move closer to or further away from the support along the third slide rail.

[0019] Furthermore, the clamping claw mechanism includes a gripper assembly, a telescopic device, and a rotary motor;

[0020] The gripper assembly includes a first fixed plate, a second fixed plate, multiple gripping rods, and multiple driving rods. Each gripping rod has two ends movably connected to one end of a corresponding driving rod. One end of each gripping rod is movably connected to the first fixed plate and spaced circumferentially along the first fixed plate. The other end of each driving rod is movably connected to the second fixed plate and spaced circumferentially along the second fixed plate. The telescopic end of the telescopic device is fixedly connected to the second fixed plate and drives the second fixed plate to move linearly, causing all the driving rods to open or close the other ends of all the gripping rods. The output end of the rotary motor is fixedly connected to the first fixed plate and drives the entire gripper assembly to rotate.

[0021] Furthermore, the support is provided with multiple limiting members, which are used to limit the roll of material to be sealed to prevent it from rolling.

[0022] Furthermore, it also includes a weighing and labeling mechanism, which is used to weigh the sealed roll material and attach labels to both ends of the sealed roll material.

[0023] Furthermore, the bag film feeding mechanism includes a heat sealing device, which is used to heat seal the end of the bag film that has been pulled out and is away from the bag opening, so as to obtain a packaging bag with one end sealed.

[0024] Secondly, this utility model provides a bagging system, including the bagging machine described above.

[0025] As can be seen from the above, the bagging machine of this utility model sets the sealing mechanism separately outside the first frame, breaking the traditional design mode of highly integrating all functional modules on the same frame in the prior art. This separate design allows the sealing mechanism to be installed, disassembled, and replaced as an independent module, greatly improving the flexibility and maintainability of the equipment. Users can easily change the sealing mechanism with different sealing methods according to actual needs, such as switching from a tape sealing mechanism to a tie-band sealing mechanism, without replacing the entire bagging machine. This not only effectively solves the problem that existing integrated bagging machines cannot adapt to users' diverse needs for roll packaging sealing methods, but also significantly reduces users' procurement and maintenance costs. In addition, for manufacturers, this modular design also reduces the complexity of research and development and production. They only need to design and manufacture for different sealing mechanisms, without having to redesign the entire set of equipment for each sealing method, thereby improving the market competitiveness of the product. Therefore, this application, by setting the sealing mechanism separately, realizes the flexible switching of sealing methods, effectively solving the problem that roll packaging cannot be reused after opening in the prior art, and significantly improving the convenience and flexibility of packaging.

[0042] Reference Appendix Figure 1 Appendix Figure 2 and attached Figure 3 This utility model provides a bagging machine, including a bag film feeding mechanism 200, a film pulling mechanism 300, and a bag supporting mechanism 400 sequentially arranged on a first frame 100. The film pulling mechanism 300 is used to pull the bag film located at the front end of the bag film feeding mechanism 200 to the bag supporting mechanism 400, and the bag supporting mechanism 400 opens the bag film opening so that the roll material can be loaded into the bag film through the bag film opening. It also includes a clamping mechanism 500 and a sealing mechanism 600. The sealing mechanism 600 is separately arranged outside the first frame 100 and is used to close the bag film opening. The clamping mechanism 500 is set between the sealing mechanism 600 and the first frame 100 and is used to transfer the roll material 700 to be sealed placed on the first frame 100 to the sealing mechanism 600.

[0043] This application effectively solves the problem of difficult bag-sealing mechanism replacement in the prior art by separately setting the bag-sealing mechanism 600 outside the first frame 100 and introducing a clamping mechanism 500 to transfer the roll material 700 to be sealed, thus significantly improving the adaptability and flexibility of the bagging machine under different sealing methods. Compared with the solution of integrating the bag-sealing mechanism 600 onto the first frame 100, the separate setting of the bag-sealing mechanism 600 in this application makes it easier for users to replace different bag-sealing mechanisms, thereby enabling users to adopt different sealing methods and adapt to different application occasions.

[0044] The first frame 100 is the main support structure of the entire bagging machine, used to support and fix various functional modules. The bag film feeding mechanism 200 is responsible for feeding the bag film from the roll, which can be achieved by a motor-driven roller assembly or by a pneumatic clamping mechanism to achieve intermittent or continuous feeding of the bag film. The film stretching mechanism 300 stretches the bag film fed by the bag film feeding mechanism 200 to the bag-holding mechanism 400, which can consist of one or more pairs of traction rollers, with the stretching length and speed precisely controlled by a servo motor. The bag-holding mechanism 400 is responsible for opening the bag opening of the bag film to facilitate the smooth loading of the roll material, for example, by using pneumatic opening claws, vacuum suction cups, or a robotic arm. The gripping mechanism 500 is a key component connecting the first frame 100 and the sealing mechanism 600. It is used to grip and transfer the roll of material 700, which has been filled with film and is ready to be sealed, from the first frame 100 to the sealing mechanism 600. It can take various forms, such as a robotic arm, a suction cup gripper, or a clamp gripper. The sealing mechanism 600 is one of the core innovations of this application. It is set independently of the first frame 100 and is specifically used to seal the roll of material 700 that has been filled with film and is ready to be sealed.

[0045] Specifically, during the operation of the bagging machine, the bag film feeding mechanism 200 first feeds the bag film out of the roll. Then, the film pulling mechanism 300 precisely stretches the fed bag film to a predetermined position, above the bag-opening mechanism 400. At this time, the bag-opening mechanism 400 activates, opening the bag opening to create an opening for the roll material to enter. The roll material 700 to be sealed is placed at a designated position on the first frame 100 via a conveying device (not shown), aligned with the opened bag opening. Under the action of gravity or an auxiliary pushing mechanism, the roll material is smoothly loaded into the bag film through the opened opening. After bagging is complete, the clamping mechanism 500 activates, precisely clamping the roll material 700 to be sealed placed on the first frame 100. The clamping mechanism 500 smoothly transfers the roll material 700 to be sealed from the first frame 100 to a separately configured sealing mechanism 600. Once the roll of material 700 to be sealed is placed on the sealing mechanism 600, the sealing mechanism 600 begins to perform its sealing function, sealing the bag opening. The entire process achieves automated and modular operation from bag film supply and bagging to sealing.

[0046] The core innovation of the bagging machine provided in this application lies in the separate placement of the sealing mechanism 600 outside the first frame 100. This design makes the sealing mechanism 600 an independently replaceable module. Compared to the traditional approach of integrating the sealing mechanism 600 onto the first frame 100, the independent placement method of this application has significant advantages. In traditional integrated designs, the sealing mechanism is tightly connected to other components. Changing the sealing mechanism for different sealing methods often requires a large-scale modification of the entire bagging machine, which is time-consuming, labor-intensive, and costly. However, by making the sealing mechanism 600 independent, users can simply replace the corresponding sealing mechanism 600 according to their actual needs, such as when tape sealing, tie sealing, or other special sealing methods are required, without modifying other mechanisms on the first frame 100.

[0047] Furthermore, the introduction of the clamping mechanism 500 further enhances the flexibility and adaptability of this application. The clamping mechanism 500 is positioned between the sealing mechanism 600 and the first frame 100, and its function is to precisely transfer the roll of material 700 to be sealed from the first frame 100 to the sealing mechanism 600. This transfer mechanism ensures that different types of sealing mechanisms 600 can seamlessly integrate with the bagging process on the first frame 100. For example, when a user needs to switch from tape sealing to tie-tie sealing, they only need to replace the original tape sealing mechanism with a tie-tie sealing mechanism, ensuring that the clamping mechanism 500 can accurately place the roll of material onto the new tie-tie sealing mechanism. This modular and replaceable design greatly simplifies the complexity of equipment maintenance and functional upgrades, reduces user operating costs, and enables the bagging machine to quickly adapt to market demands for diverse sealing methods. Therefore, the bagging machine of this application, while maintaining efficient automated production, significantly improves its adaptability and flexibility in different application scenarios.

[0048] Reference Appendix Figure 4 Appendix Figure 5 and attached Figure 6 In some embodiments, the sealing mechanism 600 includes a second frame A610, on which a roller A611 is provided. The roller A611 is used to support the roll material 700 to be sealed and drive the roll material 700 to be sealed to rotate around its own axis.

[0049] The sealing mechanism 600 also includes a sealing mechanism, which includes two folding parts A620 arranged opposite to each other on the left and right sides of the roller A611, and an adhesive tape pasting part A630.

[0050] The folding section A620 includes an upward control lever A621 and a gathering control lever A622. The upward control levers A621 of the two folding sections A620 extend in opposite directions in the left and right directions and interfere with the excess packaging film 710 at the end of the roll material 700 to be sealed. The two upward control levers A621 are used to control the upward folding of the excess packaging film 710.

[0051] The gathering control lever A622 is slidably mounted on the first slide rail A640 in the left and right direction. The two gathering control levers A622 can move closer to each other in the left and right direction through the corresponding first slide rail A640 so that the excess packaging film 710 after being flipped up is gathered by the pressure of the two gathering control levers A622.

[0052] The folding part A620 is slidably mounted on the second slide rail A800 in the front-back direction. The two folding parts A620 can move backward synchronously so that the excess packaging film 710 after being gathered is folded around the periphery of the roll material 700 to be sealed by the two upward control levers A621.

[0053] The adhesive tape applicator A630 is used in conjunction with the roller A611 to apply and wrap the adhesive tape around the periphery of the roll material 700 to be sealed (specifically, after the excess packaging film 710 is folded around the periphery of the roll material 700 to be sealed, the roller A611 drives the roll material 700 to be sealed to rotate, thereby applying and wrapping the adhesive tape around the periphery of the roll material 700 to be sealed, thus sealing the roll material 700 to be sealed).

[0054] This application uses tape wrapping sealing instead of traditional heat sealing. In practical applications, the seal can be opened without damaging the film packaging by removing the tape, allowing for secondary use or repackaging. For example, the film packaging can be heat-sealed at one end and sealed with the tape of this application at the other end, thus effectively solving the problem that roll packaging cannot be reused after opening in the prior art, and significantly improving the convenience and flexibility of packaging.

[0055] Specifically, the second frame A610 serves as the support structure for the sealing mechanism 600. Rollers A611 mounted on it are configured to support the roll of material 700 to be sealed and, via a drive mechanism (not shown in the figure), rotate the roll of material 700 around its own axis. The rollers A611 ensure the stability and operability of the roll of material 700 during the sealing process.

[0056] The sealing mechanism mainly consists of two opposing folding sections A620 and an adhesive tape pasting section A630. The two folding sections A620 are symmetrically arranged on the left and right sides of the roller A611, used to fold excess packaging film 710. Each folding section A620 includes an upward folding control lever A621 and a gathering control lever A622. The upward folding control lever A621 extends in opposite directions in the left-right direction, and its position is set to interfere with the excess packaging film 710 at the end of the roll 700 to be sealed, thereby effectively folding the excess packaging film 710 upward during operation. The gathering control lever A622 is slidably mounted on the first slide rail A640 and can move towards each other in the left-right direction via a drive mechanism (not shown in the figure). Its purpose is to apply pressure to the folded excess packaging film 710, causing it to gather towards the center.

[0057] Furthermore, the entire folding section A620 is slidably mounted on the second slide rail A800 in the front-to-back direction, allowing the two folding sections A620 to move backward synchronously. This movement is designed to allow the excess packaging film 710, after being gathered, to be folded flat and adhered to the periphery of the roll 700 to be sealed, under the obstruction of the upward control lever A621.

[0058] The adhesive tape applicator A630 is configured to work in conjunction with the roller A611. After excess packaging film 710 is folded and adhered to the periphery of the roll 700 to be sealed, the adhesive tape applicator A630, while the roller A611 drives the roll 700 to be sealed to rotate, applies and wraps adhesive tape around the periphery of the roll 700 to be sealed, thereby completing the sealing operation of the roll.

[0059] This application's solution effectively solves the problem that traditional sealing methods may damage the film packaging after opening, preventing the roll material from being reused. Specifically, after the roll material 700 to be sealed is transferred from the clamping mechanism 500 to the sealing mechanism 600, the roller A611 first supports and rotates the roll material 700. Subsequently, the two upward-flipping control levers A621 contact the excess packaging film 710 at the end of the roll material 700, folding it upwards. Immediately afterwards, the gathering control lever A622 moves towards the opposite side along the first slide rail A640, pressing the folded excess packaging film 710 and gathering it towards the center. Based on this, the folding part A620 moves backwards synchronously along the second slide rail A800, using the blocking effect of the upward-flipping control levers A621 to fold the gathered excess packaging film 710 flat around the circumference of the roll material 700 to be sealed. Finally, with the assistance of roller A611, the adhesive tape applicator A630 applies and wraps the adhesive tape around the folded film roll 700 to be sealed, forming a firm and reversible seal. The entire process achieves neat folding and tape sealing of the excess packaging film 710 at the end of the roll, avoiding permanent damage to the film packaging.

[0060] Through the above technical solution, this application replaces the traditional heat-sealing method with tape wrapping, significantly improving the convenience and flexibility of packaging. Compared with the limitation of traditional heat sealing, which may damage the film packaging once opened, the tape sealing method of this application allows users to open the seal without damaging the film packaging by simply removing the tape, thereby realizing the reuse or repackaging of the roll material. This effectively solves the problem in the prior art that roll packaging cannot be reused after opening, greatly extending the service life and value of the packaging, and adapting to more diversified application needs.

[0061] Reference Appendix Figure 7 In some embodiments, the sealing mechanism 600 includes a third frame B610, on which a support B620, a sealing claw mechanism B630, and a sealing machine B640 are provided.

[0062] Support B620 is used to fix and place the roll material 700 to be sealed;

[0063] The sealing claw mechanism B630 is located at one end of the support B620 along its length and is used to clamp the excess packaging film 710 at the end of the roll to be sealed 700 and to twist and gather the excess packaging film 710 by rotating it.

[0064] The sealing machine B640 is positioned between the support B620 and the sealing claw mechanism B630 and is used to bind cable ties to the bundled excess packaging film 710.

[0065] The third frame B610 serves as the structural support for the sealing mechanism 600, bearing and securing other components. The support B620 is designed to stably hold the roll of material 700 to be sealed, ensuring its accurate positioning during the sealing process and preventing rolling or displacement. The sealing claw mechanism B630 is the core component for achieving the sealing function; it precisely grips the excess packaging film 710 at the end of the roll of material 700 to be sealed and, through its rotational motion, twists and gathers this excess film into a tight state. The sealing machine B640 is responsible for binding cable ties to the excess packaging film 710 after it has been twisted and gathered by the sealing claw mechanism B630, thus completing the final closure of the bag opening. The cable ties can be plastic, metal, or other suitable binding materials.

[0066] This application's solution effectively addresses the limitations of traditional sealing methods in specific scenarios by introducing a sealing mechanism 600 with a tying mechanism. Specifically, the roll of material 700 to be sealed is stably placed on the support B620, ensuring the accuracy of subsequent operations. Subsequently, the tying claw mechanism B630 precisely clamps the excess packaging film 710 at the end of the roll of material 700 to be sealed, and through its rotational function, twists and bundles the excess packaging film 710 to form a tight bundle structure. Finally, the tying machine B640 binds a cable tie to the bundled excess packaging film 710, thereby achieving a reliable seal on the bag opening. This mechanical tying method avoids potential damage to the material caused by heat sealing and provides the possibility of repeated opening and repackaging.

[0067] Through the above technical solution, this application provides a non-heat-sealed bag-closing method, significantly improving the flexibility and adaptability of the sealing process. The tying method allows users to easily open and reseal the bag opening according to actual needs without damaging the film packaging, thereby enabling the secondary use or repackaging of the roll material and greatly improving the convenience and economy of packaging. Furthermore, this solution avoids the limitations of heat sealing on certain heat-sensitive materials or specific film packaging, broadening the application range of bagging machines.

[0068] In some embodiments, reference is made to the appendix. Figure 7 and attached Figure 8The third frame B610 is also equipped with a lifting device B650. The lifting device B650 is connected to the sealing claw mechanism B630 and is used to drive the sealing claw mechanism B630 to move back and forth in the vertical direction, so that the sealing claw mechanism B630 can adapt to the sealing rolls 700 of different diameters and face the sealing rolls 700, thereby ensuring stable clamping of excess packaging film 710.

[0069] Specifically, the lifting device B650 can be understood as a mechanical structure capable of providing vertical displacement, its purpose being to adjust the height of the sealing claw mechanism B630. For example, the lifting device B650 can be, but is not limited to, an electric push rod, a cylinder, a screw lifting platform, or a hydraulic cylinder, etc., driven by a motor or pneumatic pressure to achieve precise lifting and lowering of the sealing claw mechanism B630. The telescopic end of the lifting device B650 is fixedly connected to the main body structure of the sealing claw mechanism B630. When the lifting device B650 is activated, its telescopic end will drive the sealing claw mechanism B630 to move vertically upwards or downwards. This reciprocating movement in the up-down direction allows the sealing claw mechanism B630 to adjust its height according to the actual diameter of the roll of material 700 to be sealed, ensuring that its clamping position is always at a suitable height for excess packaging film 710, thereby achieving compatibility with rolls of different sizes.

[0070] The solution in this application introduces a lifting device B650, making the height of the sealing claw mechanism B630 adjustable. When sealing rolls of material 700 of different diameters is required, the lifting device B650 is driven, causing the sealing claw mechanism B630 to move upward or downward until the clamping part of the sealing claw mechanism B630 is at the same horizontal height as the excess packaging film 710 at the end of the roll of material 700 to be sealed. Because the sealing claw mechanism B630 can accurately align with the excess packaging film 710, it can perform clamping and tightening operations at the optimal angle and force, effectively avoiding problems such as unstable clamping and insufficient tightening caused by height mismatch.

[0071] Through the above technical solutions, the lifting device B650 significantly improves the adaptability of the bagging machine to rolls 700 of different diameters to be sealed. The sealing claw mechanism B630 can adaptively adjust its height according to the roll size, ensuring that it can stably and accurately clamp excess packaging film 710 under any circumstances, thereby guaranteeing the uniformity and reliability of sealing quality and greatly improving the versatility and ease of operation of the equipment.

[0072] In some embodiments, reference is made to the appendix. Figure 7 and attached Figure 8 The clamping claw mechanism B630 is slidably mounted on the third slide rail B660 and can move closer to or further away from the support seat B620 along the third slide rail B660.

[0073] The solution of this application solves the problem that the sealing claw mechanism B630 cannot adapt to differences in the length or placement position of the roll of material 700 to be sealed when its position is fixed by sliding the sealing claw mechanism B630 on the third slide rail B660 and allowing it to move closer to or further away from the support B620 along the third slide rail B660. Specifically, when the length of the roll of material 700 to be sealed is short or its placement position on the support B620 is off, the sealing claw mechanism B630 can adjust its position by moving along the third slide rail B660 to ensure that it can accurately align and effectively clamp excess packaging film 710. This adjustability ensures that the sealing claw mechanism B630 is always in the optimal working position, thereby improving the accuracy and stability of clamping and tightening.

[0074] Through the above technical solution, the position of the sealing claw mechanism B630 can be flexibly adjusted according to the actual situation of the roll material 700 to be sealed, significantly improving the adaptability of the bagging machine to roll materials 700 of different specifications and placement positions. This effectively avoids problems such as unstable clamping or poor sealing effect caused by mismatched positions, thereby improving the efficiency and quality of sealing operations and reducing operational difficulty and scrap rate.

[0075] In some embodiments, reference is made to the appendix. Figure 8 The clamping claw mechanism B630 includes a gripper assembly B631, a telescopic device B632, and a rotary motor B633;

[0076] The gripper assembly B631 includes a first fixed disk B6311, a second fixed disk B6312, a plurality of gripping rods B6313, and a plurality of driving rods B6314. Each gripping rod B6313 has both ends movably connected to one end of a corresponding driving rod B6314. All gripping rods B6313 have one end movably connected to the first fixed disk B6311 and are spaced apart circumferentially along the first fixed disk B6311. The other end of all driving rods B6314 are movably connected to... The components are connected to the second fixed disk B6312 and distributed circumferentially along the second fixed disk B6312; the telescopic end of the telescopic device B632 is fixedly connected to the second fixed disk B6312 and is used to drive the second fixed disk B6312 to move linearly so that all the drive rods B6314 drive the other ends of all the clamping rods B6313 to open or close (to realize the gripper function); the output end of the rotary motor B633 is fixedly connected to the first fixed disk B6311 and is used to drive the entire gripper assembly B631 to rotate.

[0077] Specifically, the gripper assembly B631 is the core actuating component of the sealing gripper mechanism B630, designed to effectively clamp excess packaging film 710. This assembly consists of a first fixed plate B6311, a second fixed plate B6312, multiple gripping rods B6313, and multiple drive rods B6314. The first fixed plate B6311 serves as a reference, with one end of each gripping rod B6313 evenly distributed circumferentially around it via a movable connection. The other end of each gripping rod B6313 is movably connected to the second fixed plate B6312 via a corresponding drive rod B6314. This linkage structure allows the linear movement of the second fixed plate B6312 to precisely control the opening or closing of the gripping rods B6313 via the drive rods B6314, thereby achieving reliable clamping of the excess packaging film 710.

[0078] The telescopic device B632 is fixedly connected to the telescopic end of the second fixed plate B6312. Its main function is to provide linear driving force to control the second fixed plate B6312 to move in a linear direction. Through the precise control of the telescopic device B632, the opening and closing degree of the clamping rod B6313 can be adjusted to accurately clamp all excess packaging film 710.

[0079] The output end of the rotary motor B633 is fixedly connected to the first fixed plate B6311. The rotary motor B633 is responsible for driving the entire gripper assembly B631 to rotate. After the gripping rod B6313 closes and clamps the excess packaging film 710, the start of the rotary motor B633 will drive the gripper assembly B631 to rotate, thereby causing the clamped excess packaging film 710 to be twisted and gathered.

[0080] The solution of this application, through the ingenious design of the aforementioned sealing claw mechanism B630, achieves effective clamping and tightening of excess packaging film 710. Specifically, after the roll of material 700 to be sealed is placed on the support B620, the telescopic device B632 first drives the second fixed plate B6312 to move linearly, which in turn drives the clamping rod B6313 to open via the drive rod B6314, so that the excess packaging film 710 can enter the clamping range of the claw assembly B631. Subsequently, the telescopic device B632 drives the second fixed plate B6312 in the opposite direction, causing the clamping rod B6313 to close, thereby firmly clamping the excess packaging film 710. Once the excess packaging film 710 is firmly clamped, the rotary motor B633 starts, driving the entire claw assembly B631, which is fixedly connected to the first fixed plate B6311, to rotate. This rotational motion causes the excess packaging film 710 being held to be twisted along its axis until it forms a tight bundle, providing a good foundation for the subsequent binding of cable ties by the sealing machine B640.

[0081] Through the aforementioned technical solution, the internal structure of the sealing claw mechanism B630 is clearly defined. The coordinated operation of its gripper assembly B631, telescopic device B632, and rotary motor B633 ensures precise clamping and efficient twisting and bundling of excess packaging film 710. This structured design not only improves the automation and reliability of the sealing operation but also, through the precise control of the opening and closing of the gripping rod B6313 by the telescopic device B632, allows the sealing claw mechanism B630 to adapt to excess packaging film 710 of different sizes and shapes, thereby significantly improving the versatility and efficiency of the bagging machine when handling diverse roll materials. Furthermore, the stable rotational torque provided by the rotary motor B633 ensures that the excess packaging film 710 can be twisted evenly and tightly, creating ideal conditions for the binding of the cable ties, ultimately achieving both a secure and aesthetically pleasing roll seal.

[0082] In some embodiments, reference is made to the appendix. Figure 7 The support seat B620 is provided with multiple limiting elements B621, which are used to limit the roll material 700 to be sealed to prevent the roll material 700 to be sealed from rolling.

[0083] Specifically, the limiting element B621 can be understood as a structure used to restrict the displacement or rolling of the roll material 700 to be sealed on the support B620. For example, the limiting element B621 can be configured as a protrusion, a stop, a groove, or a V-groove, etc., with the purpose of engaging with the outer surface of the roll material 700 to prevent it from rolling unintendedly on the support B620. The arrangement of multiple limiting elements B621 can ensure stable support and limiting for roll materials 700 of different sizes or shapes. In practical applications, these limiting elements B621 can be distributed at intervals along the length or width of the support B620 to form a stable support area, ensuring that the roll material 700 to be sealed is firmly fixed after placement, preventing rolling or displacement during subsequent sealing operations.

[0084] In some embodiments, reference is made to the appendix. Figure 3 It also includes a weighing and labeling mechanism 900, which is used to weigh the sealed roll material and attach labels to both ends of the sealed roll material.

[0085] Specifically, the weighing and labeling mechanism 900 can be understood as a composite functional module integrating a weighing unit and a labeling unit. The weighing unit typically includes a high-precision sensor and a weighing platform for accurately measuring the actual weight of the sealed roll material. The labeling unit includes a label printer, a label peeler, and a label application device, used to generate and automatically apply labels to designated locations on the sealed roll material based on the weighing results or other preset information. For example, the label may contain key information such as the net weight of the roll material, production date, batch number, and product model. The "two opposite end faces" refer to the two opposite end faces of the sealed roll material, ensuring that the label information can be identified from different directions, thereby improving information readability and management efficiency.

[0086] The solution proposed in this application integrates a weighing and labeling mechanism 900 into a bagging machine, allowing bagged and sealed rolls of material to directly proceed to the subsequent weighing and labeling stages. Specifically, after the roll 700 to be sealed is sealed at the sealing mechanism 600, it becomes a sealed roll. This sealed roll is then conveyed to the weighing and labeling mechanism 900. At the weighing and labeling mechanism 900, the weighing unit first accurately weighs the sealed roll to obtain its weight data. Then, based on the weighing data or other preset product information, the labeling unit automatically prints the corresponding labels and accurately affixes them to both ends of the sealed roll using a robotic arm or pneumatic device. Thus, the entire process of bagging, sealing, weighing, and labeling is integrated into a continuous automated production line, requiring no manual intervention or additional equipment transfer.

[0087] In some embodiments, the bag film feeding mechanism 200 includes a heat sealing device (not shown) for heat sealing the end of the bag film that has been pulled out away from the bag opening, so as to obtain a package bag with one end sealed.

[0088] Specifically, the heat-sealing device can be understood as a device capable of melting and bonding plastic film material through heating and pressurization. Its purpose is to permanently seal a specific area of ​​the bag film, thereby forming a packaging bag with a closed bottom. In practical applications, the heat-sealing device may include a pair of heating rods or heating plates that clamp and apply heat to the bag film as it passes through, causing the bag film material to melt and fuse together at the contact area. "Heat-sealing the end of the bag film that has been pulled out away from the bag opening" refers to pre-sealing the other end of the bag film (i.e., the end that will become the bottom of the packaging bag) before or after the bag film is fed out by the bag film feeding mechanism 200 and stretched by the film pulling mechanism 300 to the bag supporting mechanism 400, but before the final bag opening is formed. In this way, it can be ensured that the packaging bag already has a closed bottom before the roll of material is loaded into the bag film, thus effectively supporting the roll of material.

[0089] The solution of this application integrates a heat-sealing device into the bag film feeding mechanism 200, so that one end of the bag film is pre-sealed before it is fed out and ready for packaging. It is precisely because the heat-sealing device reliably heat-seals the end of the bag film away from the bag opening that the originally open bag film can be transformed into a packaging bag with a closed bottom. This pre-sealing operation ensures that the packaging bag can stably support the roll material during subsequent film stretching, bag expansion, and roll loading processes, avoiding problems such as roll material slippage or leakage caused by an open bag bottom.
