Description

Technical Field

[0001] This invention relates to the field of bubble bag technology, and more specifically to an automated bubble bag sealing device. Background Technology

[0002] Bubble wrap, due to its excellent shock absorption and relatively low cost, is mainly used for packaging any items that need to be protected from damage caused by vibration, impact, squeezing, or scratching during transportation, storage, or handling. It is almost an indispensable standard packaging material, especially in the fields of electronics, fragile items, e-commerce logistics, and small-item mailing.

[0003] Most bubble bags in the current technology are sealed by heat sealing. However, when packaging heavier items, the heat seal is not strong enough and they are prone to cracking. Therefore, it is necessary to use bubble bags pre-made with hot melt adhesive and release paper to package the items and thus ensure the packaging strength.

[0004] However, during the production of this type of bubble wrap, the machine needs to stop moving during the edge-sealing process. The bubble wrap will only continue to move forward after the edge-sealing is completed. This frequent start-stopping can easily lead to uneven glue spraying from the glue nozzle. Consequently, in some areas, too much hot melt glue will be sprayed, causing it to overflow onto the outside of the release paper. The overflowing glue will stick to the machine table, conveyor belt, edge-sealing tools, guide wheels, and other parts, requiring frequent machine stops for cleaning, reducing production efficiency. The accumulated glue residue may affect the precision and normal operation of the equipment, and may even cause machine failure. Furthermore, frequent machine start-ups and stops not only cause wear and tear on the machine, but also make the bubble wrap prone to slippage, resulting in non-standard bubble bag sizes and an increased defect rate.

[0005] In view of the above, in order to overcome the above technical problems, the present invention designs an automated bubble bag sealing device, which solves the above technical problems. Summary of the Invention

[0006] This invention provides an automated bubble bag sealing device. An embossing component moves the bubble wrap forward while simultaneously pressing an adhesive application pattern on both the top and bottom sides of the bubble wrap. An adhesive application component then applies hot melt adhesive into the pattern and uses release paper to prevent overflow. An adjustment component identifies the adhesive application pattern at the bottom of the bubble wrap and adjusts the position of the edge-sealing component to prevent slippage. This solution solves the problem of frequent machine starts and stops during the edge-sealing process, which leads to excessive hot melt adhesive being sprayed onto the outside of the release paper, causing the adhesive to stick to the machine and requiring frequent shutdowns for cleaning, thus reducing production efficiency.

[0007] To achieve the above-mentioned technical objectives, the present invention provides the following technical solution:

[0008] This invention provides an automated bubble wrap sealing device, comprising a take-up roller, a material belt, a conveyor belt, a folding plate, a frame, an embossing assembly, a gluing assembly, a hot-edge sealing assembly, and an adjusting assembly. The take-up roller, material belt, and frame are arranged sequentially from right to left. The conveyor belt is mounted on the frame. The folding plate is mounted on one side of the frame. The embossing assembly and gluing assembly are mounted sequentially from right to left on the other side of the frame. The hot-edge sealing assembly is mounted on the upper left side of the frame. The adjusting assembly is mounted to the left of the hot-edge sealing assembly. The bubble wrap is mounted on the take-up roller. The embossing assembly moves the bubble wrap forward and presses a gluing ridge on the upper and lower sides of the bubble wrap. The gluing assembly applies hot melt adhesive into the gluing ridge and seals it with release paper. The hot-edge sealing assembly hot-edges the bubble wrap. The adjusting assembly identifies the gluing ridge at the lower end of the bubble wrap and adjusts the position of the hot-edge sealing assembly.

[0009] Preferably, the embossing assembly includes a motor, an embossing roller one, an embossing roller two, an adjusting plate, a positive die, and a negative die. The motor is installed on one side of the frame, the embossing roller one is installed at the output end of the motor, the motor is a servo motor, and the speed of the embossing roller one can be flexibly adjusted. The adjusting plate is installed between the motor and the frame.

[0010] In the above scheme, a cylinder is fixedly installed on the upper end of the adjusting plate, and the second embossing roller is fixedly installed on the output end of the cylinder. Gears are installed on the inner surface of the first and second embossing rollers on the adjusting plate. When the gears mesh with each other, the first embossing roller drives the second embossing roller to rotate through the gear transmission. The first and second embossing rollers are respectively installed on the upper and lower sides of the adjusting plate. The positive mold and the negative mold are respectively fixedly installed at the ends of the first and second embossing rollers and rotate with the first and second embossing rollers. The positive mold and the negative mold can be disassembled and replaced as needed. Here, the glue coating on the surface of the positive mold and the negative mold can be an icon or production date, which can avoid ink printing and further save resources.

[0011] Preferably, the male and female molds are equipped with heating rollers inside the mounting positions of the first and second embossing rollers, and the heating rollers are connected to the first and second embossing rollers through heat-conducting plates.

[0012] In the above scheme, embossing roller one and embossing roller two are made of heat-conducting metal, and the heating roller is connected to an independent power supply. By heating embossing roller one and embossing roller two through the heating roller, the bubble wrap can be shaped more quickly when pressing the glue coating pattern, avoiding the bubble wrap from springing back due to its plastic material, which would result in poor pressing effect.

[0013] Preferably, the adhesive application assembly includes a hot melt adhesive machine, a heating hose, a metering pump, an adhesive application wheel, and a shielding plate. The hot melt adhesive machine is fixedly mounted on the frame, the heating hose is connected to the hot melt adhesive machine, the adhesive application wheel is fixedly connected to the other end of the heating hose, and the metering pump is installed in the middle of the heating hose.

[0014] In the above scheme, the metering pump is connected to the drive wheel of the conveyor belt via a belt. The belt drive ensures that the speed at which the metering pump delivers hot melt adhesive is proportional to the conveyor belt speed, thereby ensuring a constant amount of adhesive applied per unit length of bubble wrap. This prevents overflow due to excessive adhesive or insufficient adhesive due to insufficient adhesive, thus guaranteeing uniform application by the applicator. The baffle plate is slidably connected to one side of the applicator and is controlled by multiple servo motors. This allows for adjustment of the applicator's width, making it suitable for various bubble bags. Simultaneously, the adhesive application pattern on the outer side of the applicator aligns with the surface of the male mold. The adhesive coating has a consistent pattern, and the protruding parts have spray nozzles. This allows the surface of the coating wheel to mesh with the patterns pressed by the embossing rollers (first and second rollers) in a gear-like manner, further preventing the bubble wrap from slipping. Simultaneously, the rotation speed of the coating wheel matches the movement speed of the bubble wrap, ensuring even adhesive application. Furthermore, because the hot melt adhesive is applied to the recessed areas within the patterns, it prevents overflow, thus avoiding the problem of overflowing adhesive adhering to the machine table, conveyor belt, ironing tools, guide rollers, and other components, requiring frequent machine stops for cleaning and reducing production efficiency.

[0015] Preferably, the adhesive application assembly further includes an installation roller, a scraper, and a pressing roller. The installation roller is mounted on the frame, and the scraper and pressing roller are installed sequentially from left to right on the right side of the adhesive application wheel.

[0016] In the above scheme, the release paper is installed on the mounting roller. The release paper is pasted to the upper end of the inner coating pattern by a scraper and pressed by the mounting roller to prevent the hot melt adhesive from contacting the air and reducing its adhesion. The pressing roller can only press the inner coating pattern and the release paper. The coating pattern near the outer side of the frame passes through the edge of the pressing roller and will not stick the hot melt adhesive to the pressing roller.

[0017] Preferably, there are two coating wheels placed side by side, and the mounting roller is installed on the right end of the coating wheel near the outside of the frame.

[0018] In the above solution, by setting two glue-applying wheels placed side by side, two sealing strips can be formed on the surface of the bubble bag simultaneously. One strip is directly used to seal the bubble bag after being glued, while the other strip has release paper attached to its surface. When customers need to return the goods, they only need to tear off the release paper to complete the secondary sealing of the bubble bag, achieving the effect of bubble bag recycling. At the same time, this invention can directly fill the items into the bubble bag and automatically complete the sealing, compared to the prior art which requires...

[0019] Preferably, the hot edge assembly includes a controller, an adjustment frame, a heat sealing roller, and a heat sealing strip, with the controller mounted on one side of the frame.

[0020] In the above scheme, the adjusting frame is installed on the upper end of the machine frame, a pair of heat sealing rollers are installed on the adjusting frame, the heat sealing strip is installed on the surface of the heat sealing rollers, and the surface of the heat sealing strip is arc-shaped.

[0021] In the above scheme, the controller is a PLC controller used to control the movement and coordination of various components. The adjustment frame is fixedly installed on the machine frame. The heat sealing rollers have a distance between them, and only the heat sealing strips installed on the heat sealing rollers can just make contact when they get close. The rotation speed of the heat sealing rollers changes regularly, so that when the part to be heat sealed is close to the two heat sealing rollers, the heat sealing strips just rotate to the relative position. During the heat sealing of the bubble wrap, the rotation speed of the heat sealing rollers is consistent with the moving speed of the bubble wrap. The above method is controlled by the controller, which avoids the problem of constantly starting and stopping the machine in the traditional heat sealing method.

[0022] Preferably, the adjustment assembly includes a vision sensor and an electric telescopic rod. The vision sensor is mounted on the upper end of the frame, and the electric telescopic rod is mounted on the adjustment frame, with the vision sensor mounted close to the surface of the frame.

[0023] In the above solution, when the lower surface of the bubble wrap passes over the top of the vision sensor, the embossing component also presses a texture on the lower end of the bubble wrap. At this time, the vision sensor only needs to use the rotation angle of the heat sealing roller and the specific position of the bubble wrap to determine whether the position of the heat sealing roller is accurate. The heating edge component can be pulled laterally by the electric telescopic rod to compensate for possible slippage of the bubble wrap or errors caused by mechanical wear.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. This invention uses an embossing component to press two adhesive application lines onto the surface of the bubble wrap. The adhesive application lines, identical to those on the outer surfaces of the male and female molds within the embossing component, are also set on the adhesive application wheel. The adhesive application lines on the bubble wrap surface and the adhesive application wheel engage in a gear-like manner, applying hot melt adhesive into the adhesive application lines on the bubble wrap surface. Release paper is then placed over the outer surface of the adhesive-coated film. This method avoids the problem of excessive hot melt adhesive overflowing beyond the release paper. Simultaneously, the embossing component drives the bubble wrap forward, and the adhesive application lines on the surface of the embossing component prevent the bubble wrap from slipping.

[0026] 2. This invention uses an adjustment component to visually identify the position of the bubble wrap by recognizing the adhesive lines pressed by the embossing component at the lower end of the bubble wrap. This allows for the detection of any deviation in the position of the heat sealing component. Furthermore, since the surface of the heat sealing strip is arc-shaped, the rotation of the heat sealing roller can achieve a sealing effect on the bubble wrap, avoiding machine wear caused by frequent start-ups and stops, as well as the problem of the bubble wrap slipping easily.

[0027] 3. This invention, by setting two gluing wheels, can simultaneously form two sealing strips on the surface of the bubble bag. One strip, after being coated with glue, is used directly to seal the bubble bag, while the other strip has release paper attached to its surface. When customers need to return goods, they only need to tear off the release paper to complete the secondary sealing of the bubble bag, achieving the effect of bubble bag recycling. At the same time, this invention can directly fill the bubble bag with items and automatically complete the sealing, saving manpower compared to the existing technology that requires manual tearing of release paper for packaging.

[0049] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0050] As one embodiment of the present invention, reference Figures 1 to 7 An automated bubble wrap sealing device includes a take-up roller 1, a material belt 2, a conveyor belt 3, a folding plate 4, a frame 5, an embossing assembly 6, a gluing assembly 7, a hot-edge sealing assembly 8, and an adjusting assembly 9. The take-up roller 1, material belt 2, and frame 5 are arranged sequentially from right to left. The conveyor belt 3 is mounted on the frame 5. The folding plate 4 is mounted on one side of the frame 5. The embossing assembly 6 and the gluing assembly 7 are mounted sequentially from right to left on the other side of the frame 5. The hot-edge sealing assembly 8 is mounted on the upper left side of the frame 5. The adjusting assembly 9 is mounted on the left side of the hot-edge sealing assembly 8. The bubble wrap is mounted on the take-up roller 1. The embossing assembly 6 moves the bubble wrap forward and presses glue lines on the upper and lower sides of the bubble wrap. The gluing assembly 7 applies hot melt adhesive into the glue lines and seals them with release paper. The hot-edge sealing assembly 8 hot-edges the bubble wrap. The adjusting assembly 9 identifies the glue lines at the lower end of the bubble wrap and adjusts the position of the hot-edge sealing assembly 8.

[0051] This invention uses an embossing component 6 to press two adhesive application lines onto the surface of the bubble wrap. The embossing component 6 also features adhesive application lines identical to those on the outer surfaces of the male and female molds 65 and 66. The adhesive application lines on the bubble wrap surface are engaged with the adhesive application wheel 74 in a gear-like manner to apply hot melt adhesive into the lines. Release paper is then placed over the outer surface of the adhesive-coated film. Furthermore, the invention uses an adjustment component 9 to visually identify the position of the bubble wrap by recognizing the adhesive application lines pressed by the embossing component 6 at the lower end of the bubble wrap, thereby detecting any deviation in the position of the hot-sealing component 8. Simultaneously, because the surface of the heat-sealing strip 84 is arc-shaped, the rotation of the heat-sealing roller 83 achieves a sealing effect on the bubble wrap, preventing machine wear caused by frequent start-ups and stops and avoiding the problem of the bubble wrap slipping easily.

[0052] As one embodiment of the present invention, reference Figures 3 to 4 The embossing assembly 6 includes a motor 61, an embossing roller 62, an embossing roller 63, an adjusting plate 64, a male mold 65, and a female mold 66. The motor 61 is mounted on one side of the frame 5, and the embossing roller 62 is mounted on the output end of the motor 61. The motor 61 is a servo motor, and its output shaft is connected to the roller shaft of the embossing roller 62 through a set of synchronous pulleys and a synchronous belt, thereby precisely controlling the speed and angle of the embossing roller 62. Embossing roller 62 and embossing roller 63 rotate synchronously in opposite directions via meshing gears, ensuring precise alignment of the male mold 65 and female mold 66. An adjusting plate 64 is installed between the motor 61 and the frame 5. A cylinder is fixedly installed on the upper end of the adjusting plate 64, and embossing roller 63 is fixedly installed at the cylinder's output end. Gears are installed on the inner surfaces of embossing rollers 62 and 63 within the adjusting plate 64. When the gears mesh, embossing roller 62 drives embossing roller 63 to rotate via gear transmission. Embossing rollers 62 and 63 are respectively installed on the upper and lower sides of the adjusting plate 64. The male mold 65 and female mold 66 are fixedly installed at the ends of embossing rollers 62 and 63, respectively, and rotate with them. The male mold 65 and female mold 66 can be disassembled and replaced as needed. The surface coating of the male mold 65 and female mold 66 can be an icon or production date, avoiding ink printing and further saving resources.

[0053] As one embodiment of the present invention, reference Figures 3 to 4The male mold 65 and female mold 66 are equipped with heating rollers 67 inside the mounting positions of embossing roller 1 62 and embossing roller 2 63. The heating roller 67 is connected to embossing roller 1 62 and embossing roller 2 63 through a heat-conducting plate 68. Embossing roller 1 62 and embossing roller 2 63 are made of heat-conducting metal. The heating roller 67 is connected to an independent power supply. By heating embossing roller 1 62 and embossing roller 2 63 through heating roller 67, the bubble wrap can be shaped more quickly when pressing the glued texture, avoiding the bubble wrap from springing back due to its plastic material, which would result in poor pressing effect.

[0054] As one embodiment of the present invention, reference Figures 5 to 6 The adhesive application assembly 7 includes a hot melt adhesive machine 71, a heating hose 72, a metering pump 73, an adhesive application wheel 74, and a shielding plate 75. The hot melt adhesive machine 71 is fixedly mounted on the frame 5. The heating hose 72 is connected to the hot melt adhesive machine 71. The adhesive application wheel 74 is fixedly connected to the other end of the heating hose 72. The metering pump 73 is installed in the middle of the heating hose 72. The metering pump 73 is connected to the drive wheel of the conveyor belt via a belt. Through belt drive, the speed at which the metering pump 73 transmits hot melt adhesive is proportional to the transmission speed of the conveyor belt 3, ensuring that the amount of hot melt adhesive in the adhesive application wheel 74 is just right, thereby ensuring that the adhesive application wheel 74 is coated evenly. The shielding plate 75 is slidably mounted on the adhesive application wheel bracket along the axial direction of the adhesive application wheel 74, and its position is driven by a servo motor. It is used to shield part of the spray holes 741 on the surface of the adhesive application wheel 74, thereby adjusting the effective adhesive application width. This method allows for adjustment of the adhesive application width of the coating roller 74, making it suitable for various sizes of bubble bags. The outer coating pattern of the coating roller 74 matches the surface pattern of the male mold 65, and the protruding portion has spray nozzles 741. This design creates a gear-like meshing effect between the surface of the coating roller 74 and the coating patterns pressed by the embossing rollers 62 and 63, further preventing bubble wrap slippage. Simultaneously, the rotation speed of the coating roller 74 matches the moving speed of the bubble wrap, ensuring even adhesive application. Furthermore, by applying the hot melt adhesive to the recessed areas within the coating patterns, overflow is prevented, thus solving the problem of overflowing adhesive adhering to the machine table, conveyor belt, heat-sealing tools, guide rollers, and other components, requiring frequent machine stops for cleaning and reducing production efficiency.

[0055] As one embodiment of the present invention, reference Figures 5 to 6The adhesive coating assembly 7 also includes an installation roller 76, a scraper 77, and a pressing roller 78. The installation roller 76 is mounted on the frame 5. The scraper 77 and the pressing roller 78 are mounted sequentially from left to right on the right side of the adhesive coating wheel 74. The release paper is mounted on the installation roller 76. The release paper is adhered to the upper end of the adhesive coating pattern near the inner side by the scraper 77 and pressed by the installation roller 76 to prevent the hot melt adhesive from contacting the air and reducing its adhesion. The pressing roller 78 can only press the adhesive coating pattern near the inner side and the release paper. The adhesive coating pattern near the outer side of the frame 5 passes through the edge of the pressing roller 78 and will not stick the hot melt adhesive to the pressing roller 78.

[0056] As one embodiment of the present invention, reference Figures 5 to 6 The invention comprises two glue-applying wheels 74 arranged side by side. The mounting roller 76 is installed on the right end of the glue-applying wheels 74 near the outer side of the frame 5. By setting two glue-applying wheels 74 arranged side by side, two sealing strips can be formed on the surface of the bubble bag at the same time. One strip is directly used for sealing the bubble bag after being glued, while the other strip has release paper pasted on its surface. When customers have a return requirement, they only need to tear off the release paper to complete the secondary sealing of the bubble bag, achieving the effect of bubble bag recycling. At the same time, the invention can directly fill the bubble bag with items and automatically complete the sealing, compared with the prior art.

[0057] As one embodiment of the present invention, reference Figure 7The heat sealing assembly 8 includes a controller 81, an adjusting frame 82, heat sealing rollers 83, and heat sealing strips 84. The controller 81 is mounted on one side of the frame 5, the adjusting frame 82 is mounted on the upper end of the frame 5, a pair of heat sealing rollers 83 are mounted on the adjusting frame 82, and the heat sealing strips 84 are mounted on the surface of the heat sealing rollers 83, with the surface of the heat sealing strips 84 being arc-shaped. The controller is a PLC controller used to control the movement and coordination of each component. The adjusting frame 82 is fixedly mounted on the frame 5. The heat sealing rollers 83 have a distance between them, and only the heat sealing strips 84 mounted on the heat sealing rollers 83 can just touch when they are close together. The controller 81 has a built-in electronic cam motion curve for the heat sealing rollers 83, which is calculated based on the constant linear velocity v of the bubble wrap, the radius R of the heat sealing roller, and the length L of each bubble bag. Within one work cycle, the controller 81 drives the servo motor of the heat-sealing roller 83 to execute this non-uniform rotation curve: the heat-sealing strip 84 rotates rapidly as it moves away from the bubble film, and decelerates as it approaches contact with the bubble film. During contact and heat sealing, its angular velocity ω is precisely controlled so that the tangential velocity of the heat-sealing strip 84 surface equals the linear velocity v of the bubble film (v=ωR). After heat sealing, it accelerates again to the starting point of the next cycle. This ensures that when the part to be heat-sealed approaches between the two heat-sealing rollers 83, the heat-sealing strip 84 has rotated to the corresponding position. Furthermore, during the heat sealing process, the rotational speed of the heat-sealing roller 83 matches the moving speed of the bubble film. This method avoids the problem of constantly starting and stopping the machine, as is required in traditional heat sealing methods.

[0058] As one embodiment of the present invention, reference Figure 7 The adjustment assembly 9 includes a vision sensor 91 and an electric telescopic rod 92. The vision sensor 91 is mounted on the upper end of the frame 5, and the electric telescopic rod 92 is mounted on the adjustment frame 82. The vision sensor 91 is mounted close to the surface of the frame 5. During operation, the vision sensor 91 captures real-time images of the embossing at the lower end of the bubble film and, through its built-in image processing unit, identifies the center line of the embossing and calculates its lateral offset Δx relative to the center of the sensor's field of view. This offset Δx is input as an error signal to the PID control module of the controller 81. The PID controller calculates the control command for the electric telescopic rod 92 based on the magnitude and trend of Δx, driving it to extend or retract by the corresponding length, thereby moving the entire hot-stamping assembly 8 laterally and bringing Δx close to zero. This achieves dynamic compensation for possible lateral deviation of the bubble wrap, ensuring the accuracy of the hot-stamping position. At this time, the vision sensor 91 only needs to use the rotation angle of the heat-sealing roller 83 and the specific position of the bubble wrap to determine whether the position of the heat-sealing roller 83 is accurate. The electric telescopic rod 92 can be used to pull the hot-stamping assembly 8 laterally to compensate for possible slippage of the bubble wrap or errors caused by mechanical wear.

[0059] As one embodiment of the present invention, reference Figure 2 The frame 5 is equipped with a second folding plate 10 at its end. When the bubble bag passes through the second folding plate 10, the glued part of the bubble bag near the outside passes through the outer part of the second folding plate 10. A pressure roller 101 is installed at the right end of the second folding plate 10. By installing the second folding plate 10 at the end of the frame 5, the sealed part that has been coated with hot melt adhesive can be attached to the bubble bag. At the same time, the pressure roller 101 presses it tightly, automatically completing the sealing. Compared with the prior art, which requires manual tearing of release paper for packaging, it saves manpower.

[0060] Working principle: The embossing component 6 moves the bubble wrap forward while pressing an adhesive application pattern on both the top and bottom sides of the bubble wrap. The adhesive application component 7 then applies hot melt adhesive into the adhesive application pattern and uses release paper to prevent the hot melt adhesive from overflowing. The adjustment component 9 identifies the adhesive application pattern at the bottom of the bubble wrap and adjusts the position of the edge heating component 8 to prevent the bubble wrap from slipping. Finally, the bubble bag is folded and pressed tightly to automatically complete the sealing.

[0061] Specifically, the bubble wrap is placed on the take-up roller 1 and transferred to the conveyor belt 3 via the lower end of the material belt 2. The item is transferred from the material belt 2 to the bubble wrap on the surface of the conveyor belt 3. The cylinder pushes the embossing roller 63 downward to clamp the bubble wrap. While moving the bubble wrap forward, two adhesive lines are pressed into one side of the bubble wrap. The other end of the bubble wrap is folded together by the folding plate 4 to form the basic shape of the bubble bag. The adhesive roller 74 rotates continuously along the adhesive lines, applying hot melt adhesive into the adhesive lines. Release paper is then used to adhere to one of the adhesive lines, and finally, it is pressed tightly. When the part that needs to be heat-sealed is close to the two heat-sealing rollers 83... At the same time, the heat sealing strip 84 rotates to the corresponding position to heat seal the part. During the heat sealing process of the bubble wrap, the rotation speed of the heat sealing roller 83 is consistent with the moving speed of the bubble wrap. When the lower surface of the bubble bag passes over the top of the vision sensor 91, since the embossing component 6 also presses the texture on the lower end of the bubble wrap, the vision sensor 91 only needs to use the rotation angle of the heat sealing roller 83 and the specific position of the bubble wrap to determine whether the position of the heat sealing roller 83 is accurate. It can also use the electric telescopic rod 92 to pull the edge heating component 8 laterally to compensate for possible slippage of the bubble wrap or errors caused by mechanical wear. When the bubble bag passes through the second folding plate 10, the glued part of the bubble bag near the outside passes through the outer part of the second folding plate 10. The right end of the second folding plate 10 is equipped with a pressure roller 101. By installing the second folding plate 10 at the end of the frame 5, the sealing part that has been coated with hot melt adhesive can be attached to the bubble bag, and at the same time, the pressure roller 101 presses it tightly to automatically complete the sealing.

[0062] The technical features disclosed above are not limited to combinations of the disclosed features with other features. Those skilled in the art may also make other combinations of the technical features according to the purpose of the disclosure in order to achieve the purpose of this disclosure.
