Description

Technical Field

[0001] This utility model belongs to the field of packaging sealing technology, and specifically relates to an adhesive sealing device. Background Technology

[0002] In the packaging of roll materials, sealing the bags is often necessary to achieve effective protection and storage. Currently, the industry widely uses transverse heat sealing of the roll material bags. This method involves wrapping the roll material with film and then applying high temperature and pressure to the entire roll and both ends using a heating device, causing the film packaging to fuse and form a closed structure. However, this traditional sealing technology has shortcomings: when the roll material needs to be reused or repackaged, the joints of the heat-sealed package are difficult to open completely and reseal. Forcibly opening it will damage the heat-sealed structure, making it impossible to repackage it in the same way. Repackaging is not only cumbersome but also affects the packaging effect and protective performance. Therefore, after opening, the opened film packaging is generally discarded. It is evident that the shortcomings of existing packaging methods reduce the convenience and flexibility of roll material packaging.

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

[0004] The purpose of this invention is to provide an adhesive sealing device that solves the problem that heat sealing of roll packaging in the prior art makes it difficult to reuse or repackage film packaging, thus significantly improving the convenience and flexibility of packaging.

[0005] In a first aspect, this utility model provides an adhesive sealing device, including a 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.

[0006] The adhesive sealing device further 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;

[0007] 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.

[0008] 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.

[0009] 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 two upward control levers.

[0010] 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.

[0011] This utility model provides an adhesive sealing device that replaces the traditional heat sealing method with adhesive tape wrapping, representing a significant technological advancement in the roll packaging field. Traditional heat sealing often damages the film packaging after opening, preventing reuse or repackaging, resulting in resource waste and inconvenience. This application, through its cleverly designed folding and adhesive tape application parts, achieves precise handling and tape sealing of excess packaging film.

[0012] Furthermore, the two folding sections are fixedly mounted on the same movable frame, which is slidably mounted on the second slide rail in the front-to-back direction.

[0013] Furthermore, the upward control lever is a rectangular horizontal bar extending in the left-right direction.

[0014] Furthermore, the wide side of the rectangular horizontal bar is perpendicular to the front-to-back direction.

[0015] Furthermore, the edges along the length of the rectangular horizontal bar are chamfered or rounded.

[0016] Furthermore, the convergence control lever includes a cylindrical bar extending in the vertical direction.

[0017] Furthermore, the gathering control lever includes two cylindrical bars, which are spaced apart and parallel to each other in the front-to-back direction.

[0018] Furthermore, the two cylindrical bars are fixedly connected by a positioning block, which is inserted into the upward control lever and can be locked onto the upward control lever.

[0019] Furthermore, the upward control lever is provided with a pin hole, which is used to engage with a pin to lock the positioning block onto the upward control lever.

[0020] Furthermore, the gathering control lever is fixedly connected to the corresponding upward control lever as a whole, and can move back and forth in the left and right directions by sliding the corresponding upward control lever on the first slide rail.

[0021] As described above, the adhesive sealing device of this utility model, by setting a roller bearing support and driving the roll of material to be sealed to rotate, and cooperating with the folding part to fold, gather, and fold the excess packaging film material upwards, and finally the adhesive tape adhering part to adhere and wrap the tape around the perimeter of the roll of material to be sealed, realizes tape wrapping sealing. Compared with the traditional transverse integral heat sealing method of roll film, this application uses tape sealing. When secondary use or repackaging is required, the user only needs to remove the tape to open the seal without damaging the film packaging, thereby realizing the secondary use or repackaging of the roll material. This innovative design effectively solves the problem of difficulty in completely opening and resealing heat-sealed packaging in the prior art, significantly improves the convenience and flexibility of roll material packaging, meets the user's needs for reusable and easy-to-open packaging, greatly reduces the waste rate of film packaging, and has significant economic benefits and environmental value.

[0035] It should be noted that the terms "up and down," "left and right," and "front and back" mentioned below are in conjunction with the appendix. Figure 1 The arrows are for reference.

[0036] Reference Appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 5 This utility model provides an adhesive sealing device, including a frame 100, on which a roller 110 is provided. The roller 110 is used to support the roll material 200 to be sealed and drive the roll material 200 to be sealed to rotate around its own axis.

[0037] The adhesive sealing device also includes a sealing mechanism, which includes two folding parts 300 arranged opposite to each other on the left and right sides of the roller 110, and an adhesive tape pasting part 400.

[0038] The folding section 300 includes an upward control lever 310 and a gathering control lever 320. The upward control levers 310 of the two folding sections 300 extend in opposite directions in the left and right directions and interfere with the excess packaging film 210 at the end of the roll to be sealed 200. The two upward control levers 310 are used to control the excess packaging film 210 to fold upward (specifically, during the process of the roll to be sealed 200 sitting on the roller 110 from top to bottom, the excess packaging film 210 is blocked by the two upward control levers 310 and folds upward).

[0039] The gathering control lever 320 is slidably mounted on the first slide rail 330 in the left and right direction. The two gathering control levers 320 can move closer to each other in the left and right direction through the corresponding first slide rail 330 so that the excess packaging film 210 after being flipped up is gathered by the pressure of the two gathering control levers 320.

[0040] The folding part 300 is slidably mounted on the second slide rail 500 in the front-back direction. The two folding parts 300 can move backward synchronously so that the excess packaging film 210 after being gathered is folded around the periphery of the roll material 200 to be sealed by the two upward control levers 310.

[0041] The adhesive tape applicator 400 is used in conjunction with the roller 110 to apply and wrap the adhesive tape around the periphery of the roll material 200 to be sealed (specifically, after the excess packaging film 210 is folded around the periphery of the roll material 200 to be sealed, the roller 110 drives the roll material 200 to be sealed to rotate, thereby applying and wrapping the adhesive tape around the periphery of the roll material 200 to be sealed, thus sealing the roll material 200 to be sealed).

[0042] 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.

[0043] This application provides an adhesive sealing device, mainly used for sealing roll film packaging. The frame 100 is the supporting structure of the entire device, used to fix various components. The roller 110 is the core component that carries the roll 200 to be sealed and drives its rotation; its rotational motion is the basis for subsequent adhesive tape application. The sealing mechanism is the key part for realizing film packaging and adhesive tape application, including a folding section 300 and an adhesive tape application section 400. The folding section 300 is responsible for folding, gathering, and converging excess packaging film 210, while the adhesive tape application section 400 is responsible for applying and wrapping the adhesive tape around the periphery of the roll 200 to be sealed, completing the sealing.

[0044] Specifically, the adhesive sealing device of this application includes a frame 100, which can be made of materials such as metal or high-strength plastic to provide sufficient structural stability and support. A roller 110 is mounted on the frame 100. The roller 110 can be a cylindrical structure, and its surface can be covered with an anti-slip material to ensure stable support of the roll of material 200 to be sealed. The roller 110 is driven by a motor, causing the roll of material 200 to be sealed to rotate around its own axis. For example, the roller 110 can consist of one or more rollers, connected to the motor via belt drive or gear drive, thereby achieving precise speed control.

[0045] The sealing mechanism is the core component of this application, comprising two folding sections 300 arranged opposite each other on the left and right sides of the roller 110, and an adhesive tape applicator 400. The folding sections 300 can be made of sheet metal or engineering plastic, and their structural design should ensure sufficient rigidity and stability during operation. The adhesive tape applicator 400 can be a separate module, including an adhesive tape roll, a tape feeding mechanism, and a compaction mechanism, for automatic adhesive tape supply and application.

[0046] The folding section 300 further includes an upward control lever 310 and a gathering control lever 320. The upward control levers 310 of the two folding sections 300 extend in opposite directions in the left-right direction and interfere with excess packaging film 210 at the end of the roll to be sealed 200. The upward control lever 310 can be a simple metal rod whose position and angle are precisely designed to effectively block excess packaging film 210 and cause it to fold upwards as the roll to be sealed 200 rests on the roller 110 from top to bottom. For example, the upward control lever 310 can be fixed to the side wall of the folding section 300, and its height and extension length can be adjusted according to the size of the roll to be sealed 200.

[0047] The gathering control lever 320 is slidably mounted on the first slide rail 330 in the left-right direction. The first slide rail 330 can be composed of a linear guide rail and a slider to ensure that the gathering control lever 320 can move smoothly in the left-right direction. The two gathering control levers 320 can move towards each other in the left-right direction through the corresponding first slide rails 330. For example, the gathering control levers 320 can be moved by a screw drive mechanism or a cylinder drive mechanism, and when the excess packaging film 210 after being flipped up is pressed by the two gathering control levers 320, it can be effectively gathered.

[0048] The folding section 300 is slidably mounted on the second slide rail 500 in the front-to-back direction. The second slide rail 500 can also consist of a linear guide rail and a slider, ensuring that the folding section 300 can move smoothly in the front-to-back direction. The two folding sections 300 can move backward synchronously, so that the excess packaging film 210, after being gathered, is folded around the periphery of the roll 200 to be sealed by the two upward control levers 310. For example, the folding sections 300 can be driven by a synchronous belt drive or a rack and pinion drive mechanism to ensure that the two folding sections 300 remain synchronized during movement.

[0049] The adhesive tape applicator 400 works in conjunction with the roller 110 to apply and wrap adhesive tape around the periphery of the roll of material 200 to be sealed. Specifically, after excess packaging film 210 is folded around the periphery of the roll of material 200 to be sealed, the adhesive tape applicator 400, in conjunction with the roller 110, drives the roll of material 200 to be sealed to rotate, thereby applying and wrapping the adhesive tape around its periphery to complete the sealing. For example, the adhesive tape applicator 400 may include an adhesive tape roll from which the adhesive tape is drawn, passes through guide rollers and pressure rollers, and is evenly applied and wrapped around the periphery of the roll of material 200 to be sealed as it rotates.

[0050] In operation, the adhesive sealing device of this application first places the roll of material 200 to be sealed onto the roller 110. As the roll of material 200 rests on the roller 110 from top to bottom, the excess packaging film 210 at its ends is blocked by two upward-flipping control levers 310, causing it to flip upwards. Subsequently, two gathering control levers 320 move towards each other in the left-right direction, applying pressure to the flipped-up excess packaging film 210, causing it to gather towards the center. After the excess packaging film 210 has gathered, two folding parts 300 move backwards synchronously, causing the gathered excess packaging film 210 to be blocked again by the upward-flipping control levers 310, thus folding it around the periphery of the roll of material 200 to be sealed. Finally, the adhesive tape applicator 400, in conjunction with the roller 110, drives the roll of material 200 to rotate, applying and wrapping the adhesive tape around the periphery of the roll of material 200 to be sealed, completing the sealing process. The entire process automates the handling of excess packaging film 210 at the end of the roll and seals it with tape, effectively solving the problem of secondary utilization caused by traditional heat sealing methods.

[0051] The adhesive sealing device of this application represents a significant technological advancement in the roll packaging field by replacing the traditional heat sealing method with adhesive tape wrapping. Traditional heat sealing methods often damage the film packaging after opening, making it impossible to reuse or repackage, resulting in resource waste and inconvenience. This application, through its cleverly designed folding section 300 and adhesive tape application section 400, achieves precise handling and tape sealing of excess packaging film 210.

[0052] Compared to existing technologies, the core innovation of this application lies in its non-destructive sealing method. The seal can be opened without damaging the film packaging simply by removing the tape, enabling secondary use or repackaging. For example, in some applications, roll materials may need to be used in batches, or temporary opening for inspection is required during transportation. The tape sealing method of this application perfectly meets these needs, which traditional heat sealing methods cannot achieve. Furthermore, the device structure of this application is relatively simple and easy to operate, effectively improving production efficiency and reducing packaging costs. This innovation not only enhances the convenience and flexibility of roll material packaging but also aligns with current sustainable development and environmental protection principles, yielding significant economic and social benefits.

[0053] In some embodiments, reference is made to the appendix. Figure 1 and attached Figure 2 The two folding parts 300 are fixedly mounted on the same movable frame 600, and the movable frame 600 is slidably mounted on the second slide rail 500 in the front-back direction.

[0054] The movable frame 600 can be understood as a support platform or frame, designed to connect the two folding sections 300 into a single unit. By fixing the two folding sections 300 onto the same movable frame 600, their relative positions remain constant during movement. The movable frame 600 slides along the second slide rail 500 in the front-to-back direction, meaning it can perform linear reciprocating motion along the guide of the second slide rail 500. The second slide rail 500 provides stable support and precise guidance for the movable frame 600, ensuring its smoothness and accuracy during movement. For example, the movable frame 600 can be constructed from a metal plate or profile with sufficient rigidity, and the second slide rail 500 can be a pair of parallel linear guide rails. The movable frame 600 achieves low-friction sliding by engaging with the guide rails via a slider.

[0055] The solution proposed in this application effectively solves the synchronization problem that may occur when the two folding parts 300 are driven independently by integrating the two folding parts 300 onto the same movable frame 600 and allowing the movable frame 600 to slide along the second slide rail 500. Because the two folding parts 300 are rigidly connected, they will inevitably move synchronously with the same speed and displacement under the drive of the movable frame 600, eliminating the need for a complex independent control system to coordinate their movements. This integrated design simplifies the drive mechanism; for example, only one drive source is needed to act on the movable frame 600 to achieve synchronous movement of the two folding parts 300, thereby reducing the structural complexity and control difficulty of the device.

[0056] The above technical solution achieves precise synchronous movement of the two folding sections 300, avoiding synchronization errors and control complexity that may result from independent driving. This integrated design significantly simplifies the mechanical structure and control system of the device, reducing manufacturing costs and maintenance difficulty. Simultaneously, because the synchronization of the folding sections 300 is reliably guaranteed, the folding process of excess packaging film 210 becomes more stable and efficient, improving the quality and efficiency of the sealing operation and ensuring the consistency of the sealing effect of the roll of material 200 to be sealed.

[0057] In some embodiments, reference is made to the appendix. Figure 3 The upward control lever 310 is a rectangular horizontal bar extending in the left and right direction.

[0058] Specifically, the upward-flipping control lever 310 is designed as a rectangular horizontal bar. This rectangular bar extends horizontally to ensure it effectively covers and interferes with the excess packaging film 210 at the end of the roll 200 to be sealed, thereby achieving a stable upward-flipping operation of the excess packaging film 210. The rectangular bar's structure is relatively simple, easy to manufacture, and has low material costs, which helps reduce the overall manufacturing cost of the device. At the same time, its regular geometry facilitates installation and maintenance, improving the device's practicality.

[0059] The solution proposed in this application effectively solves the problems of complex structure, high manufacturing cost, and insufficient practicality that may exist with traditional upward-flipping control levers by designing the upward-flipping control lever 310 as a rectangular horizontal bar extending in the left-right direction. The simple geometry of the rectangular horizontal bar simplifies its processing technology, reduces the complexity of the production process, and thus directly reduces manufacturing costs. In addition, this structural design also allows the upward-flipping control lever 310 to provide a stable and uniform contact surface when interfering with excess packaging film 210, ensuring that the excess packaging film 210 can be smoothly and effectively flipped upward, further improving the operational reliability and practicality of the device.

[0060] Through the above technical solution, the upward-flipping control lever 310 adopts a rectangular horizontal bar structure extending in the left and right directions. Its structure is simple and the manufacturing process is mature, which significantly reduces production costs and maintenance difficulties. This design not only ensures the effectiveness and stability of the upward-flipping control lever 310 when controlling the upward flipping of excess packaging film 210, but also improves the economy and practicality of the entire adhesive sealing device, making the device more competitive in practical applications.

[0061] In some embodiments, reference is made to the appendix. Figure 1 Appendix Figure 2 and attached Figure 3 The wide side of the rectangular horizontal bar is perpendicular to the front-to-back direction (the rectangular horizontal bar has a narrow side and a wide side. Since the folding control of the excess packaging film 210 is more difficult than the upward folding control, and the contact area between the wide side and the excess packaging film 210 is larger, it is more conducive to the stable folding of the excess packaging film 210. Therefore, arranging the wide side perpendicular to the front-to-back direction is conducive to ensuring that the excess packaging film 210 is folded smoothly).

[0062] The solution in this application maximizes the contact area between the rectangular bar and the excess packaging film 210 during the folding process by setting the wide side of the upward control lever 310 perpendicular to the front-back direction. Due to the increased contact area, the rectangular bar's blocking and guiding effect on the excess packaging film 210 is more stable and uniform, effectively preventing the excess packaging film 210 from shifting, wrinkling, or being incompletely folded during the folding process. Especially when the excess packaging film 210 needs to be folded around the periphery of the roll to be sealed 200, this wide-surface contact provides stronger support and pressure, ensuring that the excess packaging film 210 can be flat and tightly adhered to the periphery of the roll to be sealed 200, providing a good foundation for subsequent adhesive tape application.

[0063] Through the above technical solution, since the wide side of the rectangular horizontal bar is perpendicular to the front-to-back direction, the contact area between the upward control lever 310 and the excess packaging film 210 is significantly increased, thus providing more stable and reliable support during the folding process of the excess packaging film 210. This effectively solves the problem of unstable folding and easy deviation of the excess packaging film 210 due to insufficient contact area in traditional solutions, greatly improving the folding quality and efficiency of the excess packaging film 210, ensuring the smooth progress of the sealing process, and thereby enhancing the stability and reliability of the entire adhesive sealing device.

[0064] In some embodiments, reference is made to the appendix. Figure 3 and attached Figure 4 The edges of the rectangular horizontal bars along their length are chamfered or rounded.

[0065] The solution of this application effectively eliminates the sharp parts that may exist in traditional right-angled edges by setting chamfers or rounded corners on the edges of the rectangular horizontal strip of the upward control lever 310. It is precisely because of these chamfers or rounded corners that the upward control lever 310 can make smoother, more rounded contact with the excess packaging film 210 at the end of the roll to be sealed 200 during the process of manipulating its upward or folding. This improved contact method significantly reduces the risk of the excess packaging film 210 being scratched or torn, thereby protecting the integrity of the film packaging.

[0066] Through the above technical solution, this application can effectively avoid the sharp edge of the upward control lever 310 from scratching the excess packaging film 210, thereby ensuring the integrity of the film packaging. This not only extends the service life of the film packaging, but more importantly, it ensures that the film packaging of the roll to be sealed 200 can still maintain a good condition after unsealing, thus facilitating the secondary use or repackaging of the film packaging and significantly improving the practicality and economic benefits of the device.

[0067] In some embodiments, reference is made to the appendix. Figure 3 The convergence control lever 320 includes a cylindrical bar extending in the vertical direction.

[0068] The cylindrical bar refers to a rod-like structure with a circular cross-section extending along its axial direction. Its vertical extension is designed to effectively apply pressure to the excess packaging film 210 after it has been flipped up, causing it to converge towards the center. As a preferred embodiment, the cylindrical bar can be made of metal, engineering plastics, or other materials with sufficient rigidity and wear resistance to ensure its stability and reliability during long-term use. Its cylindrical circumferential design, compared to structures with sharp edges, significantly reduces friction and scratches on the excess packaging film 210 during the converging process, thereby effectively protecting the integrity of the packaging film 210 and facilitating subsequent reuse or repackaging.

[0069] The solution proposed in this application effectively solves the problems of complex structure, high manufacturing cost, and easy damage to the packaging film caused by traditional gathering control levers by designing the gathering control lever 320 as a cylindrical bar extending in the vertical direction. The simple structure and ease of processing and manufacturing of the cylindrical bar reduce production costs and improve the economic efficiency of the device. Simultaneously, its rounded circumferential design provides a smooth contact surface when gathering excess packaging film 210, avoiding unnecessary damage to the packaging film 210 caused by sharp edges or irregular shapes. This ensures the integrity of the packaging film 210 and provides the possibility for subsequent reuse or repackaging by the user.

[0070] Through the above technical solution, the adhesive sealing device provided in this application not only gathers excess packaging film 210, but also significantly improves the structural simplicity and manufacturing cost-effectiveness of the device. More importantly, the rounded characteristics of the cylindrical bars effectively avoid scratching the packaging film 210, greatly extending the service life of the packaging film 210, allowing it to be reused or repackaged, thereby improving the environmental friendliness and economy of the packaging and bringing a better user experience.

[0071] In some embodiments, reference is made to the appendix. Figure 3 The convergence control lever 320 includes two cylindrical bars, which are spaced apart and parallel to each other in the front-to-back direction.

[0072] The solution proposed in this application effectively solves the problem of excess packaging film 210 dispersing during the gathering process by designing the gathering control levers 320 as two parallel cylindrical bars spaced apart along the front-to-back direction. When the gathering control levers 320 of the two folding sections 300 approach each other to compress the folded excess packaging film 210, the excess packaging film 210 is confined within the spaced area between the two cylindrical bars. This structure ensures that the lateral movement of the excess packaging film 210 is effectively blocked by the cylindrical bars on both sides when it is compressed, thus preventing the film from spreading outwards or inwards disorderly. In this way, the excess packaging film 210 can be gathered more concentratedly and tightly, laying a solid foundation for subsequent folding operations.

[0073] Through the above technical solution, this application can significantly improve the gathering effect of excess packaging film 210. Since the excess packaging film 210 is confined between two cylindrical bars during the gathering process, the possibility of dispersion is greatly reduced, thus ensuring that all excess packaging film 210 can be effectively and uniformly gathered. This not only improves the efficiency and success rate of the sealing operation but also ensures the neatness and aesthetics of the final seal, avoiding problems such as weak seals or poor appearance caused by film dispersion.

[0074] In some embodiments, reference is made to the appendix. Figure 3 and attached Figure 4 Two cylindrical bars are fixedly connected by a positioning block 340, which is inserted into the flip-up control lever 310 and can be locked onto the flip-up control lever 310.

[0075] Specifically, the positioning block 340 can be understood as a structural component used to connect and fix two cylindrical bars, designed to be inserted into the internal or external slot of the upward control lever 310. Through this insertion method, the positioning block 340 can slide and adjust along the width direction (i.e., the front-to-back direction) of the upward control lever 310. Once adjusted to the desired position, the positioning block 340 can be locked onto the upward control lever 310, thereby fixing the front-to-back position of the two cylindrical bars. The locking mechanism can be implemented in various ways, such as through bolts, pins, clips, or friction, to ensure that the positioning block 340 does not shift during operation.

[0076] The solution in this application introduces a positioning block 340, which allows the two cylindrical bars of the gathering control lever 320 to be positioned and locked relative to the upward control lever 310 in the front-back direction. It is precisely because the locking position of the positioning block 340 determines the front-back position of the two cylindrical bars that the gathering control lever 320 can be precisely adapted to the specific front-back position of the excess packaging film 210 on the roll to be sealed 200. When the position of the excess packaging film 210 changes, the operator can adjust the locking position of the positioning block 340 on the upward control lever 310, thereby changing the front-back position of the two cylindrical bars to ensure that they can always effectively gather the excess packaging film 210 and prevent it from dispersing.

[0077] Through the above technical solution, this application can effectively solve the problem of poor gathering effect of the gathering control lever 320 on excess packaging film 210 at different front and rear positions in the existing solution. By using the positioning block 340 to make the front and rear position of the cylindrical bar of the gathering control lever 320 adjustable, the applicability of the adhesive sealing device to rolls of material 200 of different specifications or types to be sealed is significantly improved, ensuring that excess packaging film 210 can be effectively gathered under various conditions, thereby improving the stability and efficiency of the sealing operation.

[0078] In some embodiments, reference is made to the appendix. Figure 4 The upward control lever 310 is provided with a pin hole 311, which is used to engage with a pin to lock the positioning block 340 onto the upward control lever 310.

[0079] The pin can be understood as a detachable fastener, such as a cylindrical pin, bolt, or any other structure that can pass through the pin hole 311 and press the positioning block 340 against the friction force. Its purpose is to securely fix the positioning block 340 in the preset position of the upward control lever 310 through mechanical interference, preventing it from shifting during equipment operation.

[0080] The solution of this application provides a pin hole 311 on the upward control lever 310, which, in conjunction with a locking pin, makes the connection between the positioning block 340 and the upward control lever 310 more reliable and stable. When it is necessary to adjust the forward and backward position of the convergence control lever 320, the operator can pull out the locking pin, move the positioning block 340 to the target position, and then reinsert the locking pin to achieve quick and precise locking. This locking method utilizes the tight fit between the pin and the hole, which can effectively resist external vibration and force, ensuring that the positioning block 340 will not accidentally loosen or shift during operation.

[0081] In some embodiments, reference is made to the appendix. Figure 3The gathering control lever 320 is fixedly connected to the corresponding upward control lever 310 as a whole, and can move back and forth in the left and right directions by sliding the corresponding upward control lever 310 on the first slide rail 330.

[0082] Specifically, the convergence control lever 320 and the upward tilt control lever 310 are fixedly connected as a single unit, meaning that the movement of these two components in the left-right direction is synchronous and inseparable. The convergence control lever 320 no longer requires a separate sliding mechanism or direct sliding engagement with the first slide rail 330. Instead, it uses the upward tilt control lever 310 as its carrier, sliding with the first slide rail 330 to drive the convergence control lever 320 to reciprocate in the left-right direction. This integrated design simplifies the connection between components and the motion transmission path.

[0083] The solution in this application integrates the gathering control lever 320 and the flipping control lever 310 into a single unit, eliminating the need for a separate drive or complex synchronization mechanism for the left-right movement of the gathering control lever 320. Instead, the left-right movement of the gathering control lever 320 directly depends on the sliding of the flipping control lever 310 on the first slide rail 330. When the flipping control lever 310 reciprocates along the left-right direction on the first slide rail 330, the gathering control lever 320, which is fixed to it, also moves synchronously, thereby achieving the gathering operation of excess packaging film 210. This design effectively integrates the left-right movement function of the gathering control lever 320 into the motion system of the flipping control lever 310, avoiding the need for a separate sliding mechanism or drive device for the gathering control lever 320, thus reducing the complexity of the overall mechanism.
