Description

Technical Field

[0001] This invention relates to the field of metal coil technology, and more specifically, to a fully automatic metal coil packaging machine. Background Technology

[0002] Metal coils, such as steel coils, aluminum coils, and copper coils, are high-value industrial semi-finished products formed by rolling and coiling. They are widely used in energy, transportation, electronics, and many other fields. During transportation and storage, these materials are highly susceptible to value loss due to environmental corrosion, physical collisions, or edge damage. Therefore, effective packaging protection is crucial. For this reason, metal coil packaging machines have emerged. They typically use ring winding or core winding technology to tightly wrap the protective film around the surface of the coil, achieving automated and highly efficient packaging operations.

[0003] However, when traditional packaging technology is used for ultra-thin copper foil used in new energy batteries, the copper foil has extremely high surface sensitivity, is easily oxidized and scratched, and has low physical strength. Therefore, the packaging process must achieve "zero-contact tension control" to avoid indentation or deformation caused by winding pressure. In addition, multi-layer composite packaging is required, including an inner layer of cushioning material, a middle layer of moisture-proof film, and an outer layer of protective film. At the same time, the end face of the roll material must be precisely reinforced to ensure the overall structural stability.

[0004] Currently, traditional packaging machines only support the wrapping of a single film and cannot simultaneously integrate the laying of cushioning materials. Even when operating at the lowest tension, they may still damage ultra-thin copper foil. Generally, pearl cotton padding is first pasted onto the surface of the copper foil manually, and then it is transferred to the packaging machine for outer film wrapping. However, this method is not only inefficient, but manual operation also makes it difficult to ensure the flatness and adhesion quality of the padding, which can easily produce wrinkles, bubbles or misalignment, seriously affecting the protective effect and even causing product scrap.

[0017] Compared with the prior art, the technical solution provided by the present invention has at least the following beneficial effects: (1) This solution sets up a film covering mechanism and a wrapping mechanism. When packaging roll materials, firstly, the inner layer of cushioning material is pre-wrapped on the surface of the carrier cylinder. Then, the first and second suction pumps are used to adsorb the middle moisture-proof film and the outer protective film onto the first and second suction plates. Then, the copper foil roll material to be packaged is placed on the carrier cylinder that has been covered with cushioning material. The first covering component is precisely controlled by the adjustment component to make the moisture-proof film adhere to the side end face of the roll material. The two suction plates work together to ensure that the film material is tightly attached to both ends of the roll material and forms an overlap area. Subsequently, the contact component pushes the excess film material to the outer edge to achieve precise edge alignment and heat sealing reinforcement. The whole process uses negative pressure adsorption and mechanical coordination to complete the picking, placing, laying and sealing of the film material, avoiding the surface damage problem caused by traditional packaging methods.

[0018] (2) By setting up an electric telescopic rod, a heating plate and a wrapping mechanism, the electric telescopic rod drives the heating plate to heat-press and seal the overlapping area of ​​the film material, which solves the problem of poor sealing and easy delamination by manual sealing, and ensures sealing consistency and moisture-proof performance. Subsequently, the wrapping mechanism, driven by a servo motor, drives the two semi-circular arc plates to close inward through thread transmission and linkage, so as to smoothly press the excess film material after heat sealing and tightly attach it to the cylindrical surface of the roll material, thereby achieving non-destructive, efficient and highly consistent end face sealing and overall wrapping, which significantly improves packaging quality, protection level and production automation level.

[0019] (3) By setting up a winding mechanism and a wrapping mechanism, after the end face heat sealing is completed, the semi-circular arc plate is flipped outward by the reverse drive servo motor to make room for the outer layer winding. Then, the starting end of the protective film is positioned by the electric telescopic rod and pre-pressed and fixed by the pressure roller. Then, the servo motor drives the gear ring transmission to drive the winding mechanism to make a circular motion along the arc surface of the roll material. Under constant and gentle pressure, the protective film is continuously and smoothly wrapped around the outer layer, thereby realizing the tight fit and multi-layer superposition of the outer protective film. This not only effectively resists physical collision and moisture intrusion, but also greatly improves the overall sealing, structural stability and protection level of the packaging, meeting the stringent requirements of high-reliability packaging for high-end roll materials such as ultra-thin copper foil.

[0023] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0024] The fully automatic metal coil packaging machine provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0025] like Figures 1 to 10As shown, this embodiment of the invention provides a fully automatic metal coil packaging machine, including a processing platform 1. A vertical frame 2 is fixedly connected to one side of the upper surface of the processing platform 1. A wrapping machine body 6 is installed on the front side of the vertical frame 2. A hydraulic rod 3 for supporting the wrapping machine body 6 is fixedly connected to the upper surface of the processing platform 1. A film-coating mechanism 8 for multi-layer composite wrapping of the coil is provided in the middle of the upper surface of the processing platform 1. Adjustment components for adjusting the position of the film-coating mechanism 8 are fixedly connected to both sides of the upper surface of the processing platform 1. The coating mechanism 8 includes a first covering component 81 and a second covering component 82 located directly above the processing platform 1. The first covering component 81 includes a shield 811 located on one side above the processing platform 1. A first adsorption plate 812 is fixedly connected to one side of the shield 811. Adsorption holes 813 are circumferentially opened inside the first adsorption plate 812. A suction pump 814 is fixedly installed on the outside of the first adsorption plate 812. The upper and lower sides of the first adsorption plate 812 are provided with contact components for heat sealing. The second covering assembly 82 includes a second adsorption plate 823 located on the other side above the processing platform 1. The interior of the second adsorption plate 823 is provided with flow holes 824. A second suction pump 826 is fixedly installed on the outside of the second adsorption plate 823. A carrier cylinder 825 for placing cushioning material is fixedly connected to the middle of the second adsorption plate 823. Both sides of the second adsorption plate 823 are provided with a wrapping mechanism 10 for wrapping the end face of the roll material. The inner layer of cushioning material is laid through the bearing cylinder 825, and the middle layer of moisture-proof film and the outer layer of protective film are adsorbed by the first adsorption plate 812 and the second adsorption plate 823 respectively, so as to carry out multi-layer composite packaging of the roll material; the wrapping mechanism 10 and the contact component are used to heat seal the film material, so as to achieve precise reinforcement of the end face of the roll material, and achieve zero-contact tension control throughout the packaging process to avoid damage to the ultra-thin roll material.

[0026] To address the limitations of existing metal coil packaging technology in meeting the packaging requirements of ultra-thin copper foil, traditional packaging machines suffer from limited functionality, insufficient tension control precision, and an inability to automatically and synchronously wrap multi-layer composite materials. In particular, they lack the ability to automatically lay cushioning materials, necessitating manual pre-application of the cushioning layer. This results in low efficiency, poor adhesion quality, and a tendency to produce wrinkles, bubbles, or misalignments, affecting protective effectiveness and potentially causing product damage or spoilage. The aforementioned technical solution addresses these issues by primarily employing a film-coating mechanism 8 and a wrapping mechanism 10. When packaging copper foil rolls, firstly, the inner cushioning material is pre-wrapped onto the surface of the carrier cylinder 825; then, the first suction pump 814 and the second suction pump 826 are activated respectively to stably adsorb the middle moisture-proof film and the outer protective film onto the contact surfaces of the first adsorption plate 812 and the second adsorption plate 823; next, the copper foil roll to be packaged is placed on the carrier cylinder 825 already wrapped with cushioning material, and the first covering component is precisely controlled by the adjusting component to move towards the side end of the roll, so that the middle moisture-proof film is flatly attached to one side of the roll; at the same time, the first... The first adsorption plate 812 and the second adsorption plate 823 cooperate to cover and adhere the adsorbed film material to both ends of the roll. Since the selected moisture-proof film and protective film are both larger than the roll's end face, the excess film at the edges forms an overlap area. At this point, the abutting component pushes the excess film material on the first adsorption plate 812 outwards, ensuring precise alignment and adhesion between it and the edge of the outer protective film corresponding to the wrapping mechanism 10 on the second adsorption plate 823. Then, the heating function in the abutting component is activated again to heat the overlap. The area is reliably heat-sealed to achieve complete wrapping and reinforcement of the roll material's end face. During the above operation, the placement, application, and sealing of the film material are all completed through negative pressure adsorption and mechanical coordination, avoiding the problems of indentation, scratches, or deformation on the roll material surface caused by direct contact or improper tension in traditional wrapping packaging. Moreover, this operation method is particularly suitable for high-end roll material packaging such as ultra-thin copper foil for new energy batteries, which have extremely high requirements for surface integrity. While improving packaging efficiency and consistency, it significantly reduces the intensity of manual intervention and the risk of product scrapping.

[0027] like Figures 1 to 10As shown, the shielding cover 811 has a support mechanism 9 inside for assisting in supporting the roll material. The support mechanism 9 includes a first servo motor 91 fixedly connected to the middle of the outer side of the shielding cover 811. The output end of the first servo motor 91 is fixedly connected to a first drive rod 92. The first drive rod 92 has a slot 93 inside. The outer circular surface of the first drive rod 92 is provided with a sleeve 94 fixedly connected to the shielding cover 811. One end face of the sleeve 94 is fixedly connected to a first limiting rod 96. One end of the first limiting rod 96 is fixedly connected to a limiting seat 95. A first slide block 97 is slidably connected to the middle of the first limiting rod 96. A U-shaped frame 98 is fixedly connected to the outer circular surface of the limiting seat 95. A support plate 99 is hinged inside the U-shaped frame 98. A roller 910 for contacting the roll material is rotatably connected to one end of the support plate 99. An adjusting rod 911 for adjusting the opening angle of the support plate 99 to adapt to roll materials of different specifications is hinged to the outer circular surface of the first slide block 97.

[0028] During the packaging of ultra-thin copper foil rolls, to ensure high stability and reliability of the packaging operation and prevent the rolls from shaking or shifting during the wrapping process, after the rolls are placed on the carrier cylinder 825, the first covering component 81 is precisely controlled to move towards the second adsorption plate 823 by adjusting the components; then, the first servo motor 91 is started to drive the first drive rod 92 to rotate. It should be noted that the middle layer moisture-proof film pre-covered on the first adsorption plate 812 has a circular hollow area in the center, so it will not interfere with or obstruct the rotation of the first drive rod 92; as the first drive rod 92 rotates, the sleeve 94 remains in a fixed position due to its fixed connection with the shield 811, and the position of the limiting seat 95, which is fixedly connected to it by the first limiting rod 96, also remains unchanged; the rotational motion of the first drive rod 92 is converted into the first slide 97 moving along the first limiting rod 96 via the thread. The axial movement of the slide block 97, along with the movement of the first slide block 97, pushes or pulls each support plate 99 through the adjusting rod 911, causing it to rotate synchronously around the hinge point of the U-shaped frame 98, thus smoothly opening outward or closing inward; finally, the roller 910 at the end of the support plate 99 gently abuts against the inner wall of the roll material in a rolling manner, forming a uniform radial support force; this process achieves zero-contact internal support and stabilization of the roll material, effectively solving the problem that ultra-thin roll materials (such as copper foil) are prone to deformation, wrinkles or surface damage due to their poor rigidity and susceptibility to external forces during packaging; and in this process, the adaptive support mechanism driven by the first servo motor 91 can quickly and accurately adapt to roll materials of different diameters, significantly improving the stability, automation and product yield of the packaging process, and avoiding quality problems such as packaging misalignment and film wrinkles caused by roll material displacement or vibration.

[0029] like Figures 1 to 10As shown, the contact assembly includes a fixed plate 815 fixedly connected to the outside of the first adsorption plate 812. A first electric telescopic rod 816 is fixedly connected to the top of the fixed plate 815. A protective shell 817 is fixedly connected to the top of the first electric telescopic rod 816. A heating plate 818 for heat sealing the seam of the film material is embedded inside the protective shell 817. The second covering assembly 82 also includes a bracket 821 located outside the second adsorption plate 823. A connecting plate 822 is provided between the bracket 821 and the second adsorption plate 823. A winding mechanism 12 for applying the outer protective film and a driving mechanism 11 for driving the winding mechanism 12 are provided directly above the first adsorption plate 812 and the second adsorption plate 823.

[0030] like Figures 1 to 10 As shown, the wrapping mechanism 10 includes a sleeve block 101 located in the middle of the second adsorption plate 823. The upper and lower ends of the sleeve block 101 are provided with support arms 102 fixedly connected to the bracket 821. A second drive rod 103 is rotatably connected inside the sleeve block 101. One end of the second drive rod 103 is engaged in the slot 93 of the first drive rod 92, and the other end is rotatably connected inside the bracket 821. A second limiting rod 104 is fixedly connected around one side of the outer surface of the second drive rod 103. A second slide block 105 is slidably connected at the middle of the second limiting rod 104. Fixed seats 107 are fixedly connected to the front and rear sides of the outer circular surface of the second adsorption plate 823. A semi-circular arc plate 108 for wrapping and compacting the end face film of the roll material is hinged inside the fixed seat 107. A pull rod 106 for adjusting the flip angle of the semi-circular arc plate 108 is hinged inside the second slide block 105.

[0031] After the middle layer moisture-proof film and the outer layer protective film adsorbed by the first adsorption plate 812 and the second adsorption plate 823 are initially aligned and overlapped at the end face of the roll material; firstly, the first electric telescopic rod 816 is extended, pushing the protective shell 817 at its top and the heating plate 818 embedded inside towards the film overlap area, and the heating plate 818 is used to heat-press and seal the seam of the multi-layer film material at a predetermined temperature. This step completely solves the problems of poor sealing, easy delamination, and poor appearance caused by manual sealing in traditional processes, and achieves efficient, reliable and consistent firm sealing, effectively preventing moisture intrusion and film material loosening during transportation; immediately after the heat sealing is completed, the wrapping mechanism 10 is started, that is, during the process of starting the first servo motor 91 to provide power, through a The slot 93 at the front end of the first drive rod 92 transmits the signal to the second drive rod 103 connected thereto. The rotation of the second drive rod 103 causes the second slide block 105, which is threaded to it, to move axially along the second limit rod 104. As the second slide block 105 moves, the movement is transmitted through the pull rod 106, which is hinged to it, ultimately driving the semi-circular arc plates 108 on both sides to smoothly close inward around the hinge point of the fixed seat 107. At this time, the semi-circular arc plates 108 gently and orderly wrap, compact, and tightly adhere the excess film material that has been heat-sealed at the end face to the cylindrical surface of the roll material. Through this continuous process of "heat sealing and wrapping and compaction", the packaging quality, production efficiency, and protection level of the roll material are greatly improved, and the packaging of ultra-thin roll material is completed in a non-destructive, efficient, and highly consistent manner.

[0032] like Figures 1 to 10 As shown, the adjustment assembly includes a first convex plate 13 and a second convex plate 132 fixedly connected to both sides of the upper surface of the processing platform 1. A third hydraulic rod 131 is fixedly connected to one side of the first convex plate 13, and the output end of the third hydraulic rod 131 is connected to the second cover assembly 82 to provide support and position adjustment. A fourth hydraulic rod 133 is fixedly connected to one side of the second convex plate 132, and the output end of the fourth hydraulic rod 133 is connected to the first cover assembly 81 to provide support and position adjustment. By controlling the extension and retraction of the third hydraulic rod 131 and the fourth hydraulic rod 133 respectively, the relative positions of the second cover assembly 82, the first cover assembly 81 and the roll material are adjusted to adapt to roll materials of different widths and to perform multi-layer packaging.

[0033] At the start of the packaging operation, after metal coils of different widths are placed at predetermined positions on processing platform 1, the control system independently drives hydraulic rods 131 (number three) and 133 (number four) to precisely extend and retract according to preset coil width parameters. The extension and retraction of hydraulic rod 131 directly pushes or pulls the second covering assembly 82 along a direction approaching or away from the coil axis. Simultaneously, the extension and retraction of hydraulic rod 133 drives the first covering assembly 81 to move in the opposite or coordinated direction. Through this relatively independent control, the first adsorption plate 812 can be precisely adjusted. The relative distance between the middle moisture-proof film and the second adsorption plate 823 is designed to fit the width of the current roll material, ensuring that the middle moisture-proof film and the outer protective film can be precisely aligned and cover the two ends of the roll material. In this process, the adjustment component not only achieves wide-range, infinitely precise positioning of the laminating mechanism 8, ensuring that the multi-layer film can be accurately centered and completely covered regardless of the width of the roll material, but also completely avoids waste of film material, incomplete coverage, or wrapping wrinkles caused by size mismatch. Furthermore, it lays the foundation for the final winding of the roll material after the multi-layer protective film has been wrapped.

[0034] like Figures 1 to 10 As shown, the drive mechanism 11 includes an L-shaped support plate 111 fixedly connected to the top of the bracket 821. A bracket 112 is fixedly connected to one side of the L-shaped support plate 111. A second servo motor 113 is fixedly connected to the inner side of the bracket 112. A rotating rod is fixedly connected to the output end of the second servo motor 113. A main gear 114 is fixedly connected to one end of the rotating rod. A limiting ring seat 115 is fixedly connected to one end face of the L-shaped support plate 111. A driven gear ring 116 that meshes with the main gear 114 is rotatably connected inside the limiting ring seat 115. A second electric telescopic rod 117 is fixedly connected to the inner top of the driven gear ring 116. The second electric telescopic rod 117 is fixedly connected to the winding mechanism 12 to drive it to wind the roll material with zero tension.

[0035] like Figures 1 to 10 As shown, the winding mechanism 12 includes a support frame 121 fixedly connected to the bottom of the second electric telescopic rod 117. A winding rod is rotatably connected inside the support frame 121. A protective film 122, serving as an outer protective film, is wound around the outer surface of the winding rod. A third electric telescopic rod 126 is fixedly connected to one side of the support frame 121. An auxiliary plate 125 is hinged to one end of the third electric telescopic rod 126. Both ends of the bottom of the auxiliary plate 125 are fixedly connected to hinge plates 123. One end of the hinge plate 123 is hinged to the support frame 121, and a crossbar is fixedly connected to the inner side of the other end. A pressure roller 124 for gently pressing the protective film 122 onto the surface of the roll material is rotatably connected to the outer surface of the crossbar.

[0036] To further enhance the overall packaging effect and protective strength of the roll material, after the wrapping mechanism 10 and the contact component work together to complete the heat-sealing of the multi-layer film on the end face of the roll material, the first servo motor 91 is restarted, causing the first drive rod 92 to rotate in the reverse direction. This causes the second drive rod 103, which is engaged with the first drive rod, to rotate synchronously, and the second slide block 105 to move outward along the axis of the second limit rod 104. As the second slide block 105 moves, the pull rod 106 causes the semi-circular arc plate 108 to move within the fixed seat 107. Rotating clockwise causes the two semi-circular arc plates 108 to flip outwards, making room for subsequent circumferential winding operations and avoiding interference. After the two semi-circular arc plates 108 have flipped outwards, firstly, based on the thickness of the roll material, the second electric telescopic rod 117 is activated, allowing the initial section of the protective film 122 roll carried by the winding rod on the support frame 121 to be gently placed on the surface of the roll material with completed end covering. Next, the third electric telescopic rod 126 is activated, causing it to slowly extend and push the auxiliary plate 125 downwards. Then, the auxiliary plate... 125, through the hinge plates 123 hinged at both ends, drives the lower crossbar and pressure roller 124 to press down synchronously. The pressure roller 124 presses the initial section of the protective film 122 tightly against and pre-presses it onto the outer protective film of the roll material with controllable pressure, ensuring a firm initial adhesion and laying the foundation for continuous winding. After the inner side of the protective film 122 is reliably adhered to the lower film material, the second servo motor 113 starts, and its output drives the rotating rod and main gear 114 to rotate, thereby causing the driven gear ring 116 meshing with it to rotate within the limiting ring seat 115, and... During the rotation of the driven toothed ring 116, the second electric telescopic rod 117 drives the entire winding mechanism 12 to make a circular motion on the arc surface of the roll material. During this process, the protective film 122 is continuously pulled out from the winding rod and tightly and smoothly wrapped around the arc outer surface of the roll material under the constant gentle pressure of the pressure roller 124. This not only makes the outer protective film fit the contour of the roll material better, effectively resisting physical collisions and moisture intrusion during transportation and storage, but also greatly enhances the structural strength and sealing of the overall packaging.

[0037] like Figures 1 to 10 As shown, a U-shaped bracket 4 is fixedly connected to the top of the first hydraulic rod 3, and a processing frame 5 is fixedly connected to one side of the U-shaped bracket 4. The main body 6 of the wrapping machine is installed on the front side of the processing frame 5. A convex groove is opened in the middle of the processing platform 1, and a support frame 7 is fixedly connected to the bottom of the processing platform 1. A second hydraulic rod 71 is fixedly connected to each of the four corners inside the support frame 7. The top of the second hydraulic rod 71 is fixedly connected to a base 72 for supporting the roll material. Limiting modules 74 are provided on the front and rear sides of the upper surface of the base 72. An electric push rod 73 fixedly connected to the processing platform 1 is provided at the bottom of the limiting module 74. A rolling module 14 is provided in the middle of the base 72 to allow the roll material to rotate with low resistance during the packaging process.

[0038] like Figures 1 to 10As shown, the adsorption surfaces of the first adsorption plate 812 and the second adsorption plate 823 are both covered with a flexible sealing layer to ensure the sealing performance when adsorbing the membrane material and to prevent scratches on the membrane material surface.

[0039] like Figures 1 to 10 As shown, the rolling module 14 includes a roller disposed on the upper surface of the base 72. The output end of the roller is provided with a belt drive assembly, and the top of the roller is slightly higher than the upper surface of the base 72 to support the roll material and assist its rotation.

[0040] After the protective film is applied, the third hydraulic rod 131 is activated to retract, returning the entire second covering assembly 82 to its initial position. At this time, the support mechanism 9 located within the first adsorption plate 812 provides stable support for the roll material. After the second covering assembly 82 returns to its initial position, the second hydraulic rod 71 is activated to lift the entire base 72 upwards, causing the rolling module 14 on the base 72 (composed of multiple active roller arrays driven by a motor and synchronously linked by a belt drive assembly) to contact the bottom of the roll material after the protective film has been applied. Immediately afterwards, the electric push rod 73 is activated to push the limiting module 74 inwards, mechanically limiting and centering the roll material from the front and rear directions to ensure its axis is aligned with the subsequent wrapping. The axes of the mounting stations are precisely aligned; after the initial position of the roll material is determined, the fourth hydraulic rod 133 is activated to retract, so that the entire first covering assembly 81 and the support mechanism 9 return to the initial position. The limiting module 74 (existing technology) is activated again, and the two bias rollers are used to limit the two ends of the roll material. After the roll material is limited, the first hydraulic rod 3 is activated to retract, so that the U-shaped bracket 4 drives the entire processing frame 5 and the winding machine body 6 to move down, so that the winding machine body 6 moves down to the appropriate position. Through the core-passing technology of the winding machine body 6 and the joint cooperation of the rolling module 14, the roll material is further wound with film. After the final winding is completed, the ultrasonic cutter on the external processing frame 5 instantly melts the film after completing the set number of layers.

[0041] In use, the copper foil roll to be packaged is first hoisted to a predetermined station on the processing platform 1. Then, according to the width parameters of the roll, hydraulic rods 131 and 133 are driven independently to move the second covering component 82 and the first covering component 81 along the axis of the roll, precisely adjusting the distance between the first adsorption plate 812 and the second adsorption plate 823 to match the width of the roll, thus laying the foundation for accurate alignment and complete coverage of the film. After the packaging operation officially starts, sheet-like inner cushioning material (such as coated pearl cotton) is first manually or automatically pre-applied to the surface of the carrier cylinder 825 with the non-coated side facing out. Then, the roll is placed on the carrier cylinder 825 which has been covered with cushioning material. Next, the first servo motor 91 is started, driving the first drive rod 92 to rotate, which in turn drives the first slide block 97 to move axially along the first limit rod 96; the first slide block 97 pushes multiple support plates 99 to open outward synchronously around their hinge points through the adjusting rod 911, until the rollers 910 at the ends of the support plates 99 gently abut against the inner wall of the roll material, forming a uniform radial support force; after the inner support is fixed, the first suction pump 814 and the second suction pump 826 are started respectively to stably adsorb the middle moisture-proof film and the outer protective film onto the first suction pump. On the contact surface of the auxiliary plate 812 and the second adsorption plate 823, the adjusting component controls the first covering component 81 to move towards the end face of the roll, so that the two adsorption plates simultaneously cover and press the film they adsorb onto both ends of the roll. Since the size of the film is larger than the end face of the roll, an overlap area is formed at the edge. Then, the first electric telescopic rod 816 is activated to push the protective shell 817 and the built-in heating plate 818 into the overlap area, and perform heat-press sealing on this area, thereby achieving a reliable seal on the end face and completely blocking the path of moisture intrusion. After the heat sealing is completed, the first servo motor 91 is activated again, and the first drive rod 92 drives the second drive rod 103 to rotate synchronously through the slot 93, thereby driving the second slide 105 to move axially along the second limit rod 104, and pulling the semi-circular arc plates 108 on both sides inward through the pull rod 106, gently and orderly wrapping and pressing the excess film after the end face heat sealing onto the cylindrical surface of the roll, ultimately making the packaging appearance flat and sturdy. Finally, to enhance the overall protective performance, the support mechanism 9 and the wrapping mechanism 10 are first reset (the semi-circular plate 108 is flipped outwards) to make room for the wrapping operation. Then, the second electric telescopic rod 117 is started to adjust the position of the initial section of the protective film 122 roll, so that it is gently placed on the upper surface of the roll. Next, the third electric telescopic rod 126 is started to push the pressure roller 124 down to pre-press and fix the initial section of the film. After that, the second servo motor 113 is started to drive the driven toothed ring 116 and the entire wrapping mechanism 12 to make a circular motion around the roll. Under the constant pressure of the pressure roller 124, the protective film 122 is tightly and flatly wrapped around the outer surface of the roll, thus completing the entire packaging operation.
