Description

Technical Field

[0001] The invention belongs to the technical field of vacuum insulation panel processing and relates to an adhesive tape applying device, in particular to an adhesive tape applying device for vacuum insulation panels. Background Art

[0002] Vacuum insulation panels (VIPs) are highly efficient thermal insulation materials that combine the principles of vacuum insulation with traditional insulation materials. They are manufactured using a glass fiber core and a gas-barrier composite film as the packaging, after vacuum packaging. Because they maximize the vacuum level within the panel and reduce gas convection, they achieve highly efficient insulation. Compared to other materials, VIPs, with their extremely low thermal conductivity, offer advantages such as thin insulation layer thickness, compact size, and light weight while maintaining the same insulation requirements. They are suitable for products requiring high energy efficiency and possess significant technical and economic benefits.

[0003] In the production of vacuum insulation panels, it is necessary to apply tape on both sides of the vacuum insulation panels after folding the edges. In the existing technology, the tape application is generally done manually, which is inefficient and the manual application accuracy is not high, which easily leads to a large number of defective products. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems in the existing technology and to provide a tape applying device that can apply tape to both sides of vacuum insulation panels of different widths.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] The tape applying device includes a frame, a conveying mechanism provided on the frame for conveying the vacuum insulation panel forward, and two tape machines provided on the frame and respectively located above the conveying mechanism. The two tape machines are distributed in the left and right directions. The frame is also provided with a first adjustment mechanism for adjusting the left and right distance between the two tape machines.

[0007] The conveyor mechanism transports the vacuum insulation panels from back to front. When the panels reach the bottom of the tape dispensers, two dispensers apply tape to each side of the panels. A first adjustment mechanism allows for adjustment of the left-right distance between the two dispensers, allowing for tape application to panels of varying widths, broadening the application range.

[0008] In the above-mentioned tape applying device, the first adjustment mechanism includes a guide rail extending in the left-right direction, a slide seat provided on the guide rail and slidingly engaged with the guide rail, and a locking structure for locking the slide seat to the guide rail, wherein one tape machine is fixed relative to the slide seat, and the other tape machine is fixed relative to the guide rail.

[0009] To adjust the left-right distance between two conveyors, first unlock the locking mechanism. Then, move the slide on the guide rail, driving the conveyor fixed to the slide relative to the other conveyor. Once in place, the locking mechanism locks the slide to the guide rail. This makes it easy to operate and facilitates adjustment of the left-right distance between the two conveyors.

[0010] As another solution, the first adjustment mechanism includes a guide rail extending in the left-right direction, a slide seat disposed on the guide rail and slidably engaged with the guide rail, and a locking structure for locking the slide seat to the guide rail. The two tape dispensers are respectively fixed relative to different slide seats. This allows the positions of the two tape dispensers to be adjusted, providing greater flexibility.

[0011] In order to achieve a better locking effect, the locking structure is a linear guide fixture.

[0012] In the above-mentioned tape applying device, there are two guide rails distributed along the front-to-back direction, and each guide rail is slidably fitted with a slide seat; a mounting plate is provided under each of the tape machines, wherein the front and rear ends of one mounting plate are respectively fixedly connected to different guide rails, and the front and rear ends of the other mounting plate are respectively fixedly connected to slide seats located on different guide rails.

[0013] To facilitate adjustment of the distance between the two mounting plates, they are connected by a drag chain. To adjust the distance, unlock the locking mechanism and move the other mounting plate along the guide rail. Once it is in place, the locking mechanism secures it in place. Changing the distance between the two mounting plates also changes the distance between the two conveyor belts. Supporting the conveyor belts with the mounting plates improves their stability.

[0014] In the aforementioned tape application device, an upper cover plate is positioned above each mounting plate, and the tape dispenser is mounted on the corresponding upper cover plate. A second adjustment mechanism for adjusting the height of the upper cover plate is provided between the upper cover plate and the mounting plate. Adjusting the height of the upper cover plate via the second adjustment mechanism also adjusts the height of the tape dispenser, enabling the tape dispenser to apply tape to vacuum insulation panels of varying thicknesses, thus broadening its applicability.

[0015] In the above-mentioned tape applying device, the second adjustment mechanism includes a number of guide rods vertically fixed on the mounting plate, an elastic telescopic sleeve mounted on the guide rods, and a threaded rod with a lower end threadedly connected to the mounting plate. The upper cover plate is provided with through holes corresponding to the guide rods and the threaded rods respectively. The upper ends of the guide rods and the threaded rods pass through the corresponding through holes. The elastic telescopic sleeve is located between the upper cover plate and the mounting plate. The upper end of the threaded rod is fixedly connected to a vertical adjustment handwheel pressed on the upper cover plate.

[0016] Turning the vertical adjustment handwheel rotates the threaded rod, which in turn moves up and down relative to the mounting plate, thereby driving the vertical adjustment handwheel up and down. When the vertical adjustment handwheel descends, it squeezes the upper cover, causing it to descend, lowering the tape conveyor with it and compressing the elastic sleeve. When the vertical adjustment handwheel ascends, the elastic sleeve returns to its original position, causing the upper cover to ascend, raising the tape conveyor with it. The elastic sleeve can be constructed using a spring or other similar structure.

[0017] Alternatively, the second adjustment mechanism includes several screws that rotatably engage the mounting plate. These screws are threadedly connected to the upper cover. To prevent the upper cover from rotating when the screws are rotated, vertical guide posts are fixed to the mounting plate, with the upper cover slidingly engaging the guide posts. The screws are connected via a sprocket chain drive. When one screw rotates, the remaining screws rotate synchronously in the same direction. Rotating the screws causes the upper cover to rise and fall.

[0018] In the above-mentioned tape applying device, two support plates arranged opposite to each other in the left and right directions are fixed on the upper cover plate, and an adjustment rod extending in the left and right directions is passed through the two support plates. The tape machine is located between the two support plates and is threadedly connected to the adjustment rod, and one end of the adjustment rod is fixedly connected to a horizontal adjustment handwheel.

[0019] To prevent the tape dispenser from rotating around the adjustment rod, a guide rod parallel to the adjustment rod is installed between the two support plates. The tape dispenser and the guide rod slide in unison. The adjustment rod is pivotally connected to each support plate. When the adjustment rod rotates, it drives the tape dispenser left and right, changing its horizontal position in the left-right direction. This allows the tape dispenser to apply tape to packaging bags of different widths on vacuum insulation panels of the same width.

[0020] In the above-mentioned tape applying device, the tape machine includes a fixed frame, a movable frame arranged opposite to the fixed frame, a tape roll arranged on the upper part of the movable frame, a suction cup arranged on the lower part of the movable frame, and a driver for driving the movable frame to move up and down. The tape led out from the tape roll passes around the suction cup and is adhered to the vacuum insulation panel located on the conveying mechanism under the pressure of the suction cup. A cutting component is provided between the movable frame and the fixed frame for cutting the tape between the suction cup and the vacuum insulation panel when the movable frame rises.

[0021] The actuator comprises a cylinder secured to a fixed frame, with the movable frame fixedly connected to the piston rod of the cylinder. The cylinder is a pneumatic or hydraulic cylinder, preferably a pneumatic cylinder. The cylinder is inverted, with the piston rod extending from the lower end. When the piston rod extends, it drives the mounting frame downward; when the piston rod retracts, it drives the mounting frame upward. A suction cup is rotatably connected to the movable frame, with its rotational centerline extending horizontally in the left-right direction. The back of the tape, drawn from the tape roll, passes over the suction cup from top to bottom and from back to front. Under the pressure of the suction cup, the adhesive surface of the tape adheres to the upper surface of the vacuum insulation panel. As the vacuum insulation panel is conveyed forward, the tape is continuously pulled forward and adhered to the panel, achieving automatic application of the tape to the panel. After application is complete, the actuator drives the movable frame upward, releasing the suction cup from its pressure on the panel. A cutting assembly then cuts the straightened tape between the suction cup and the panel.

[0022] In the above-mentioned tape applying device, the cutting assembly includes a cutter bracket rotatably connected to the movable frame, a cutting part provided at the free end of the cutter bracket, and a first connecting rod whose upper end is rotatably connected to the fixed frame, and the lower end of the first connecting rod is hinged to the cutter bracket.

[0023] The rotational centerline of the cutter bracket is parallel to the rotational centerline of the first connecting rod and parallel to the rotational centerline of the suction cup. The rotational centerline of the cutter bracket is located at the rear end of the cutter bracket and above the rotational centerline of the suction cup, with the cutting portion located at the front end of the cutter bracket. The lower end of the first connecting rod is hinged to the end of the cutter bracket near the cutting portion. When the movable frame rises, the rear end of the cutter bracket is also raised. Because the upper end of the first connecting rod is fixed in position, the front end of the cutter bracket, supported by the first connecting rod, swings downward about the rotational centerline, driving the cutting portion downward to contact and cut the tape between the suction cup and the vacuum insulation panel.

[0024] In the aforementioned tape applying device, the cutting portion is a cutter. The cutter is perpendicular to the cutter support, and the direction of extension of the cutter blade is parallel to the rotation centerline of the cutter support. To effectively cut the tape, the cutter blade is composed of multiple teeth, each of which has a sharp tooth tip.

[0025] In the above-mentioned tape applying device, the cutting part is a heating wire. Two heating wire seats are provided at the front end of the cutter bracket, and the heating wire is stretched between the two heating wire seats. The heating wire is parallel to the rotation center line of the cutter bracket.

[0026] In the above-mentioned tape applying device, the lower portion of the suction cup has an adsorption surface that contacts the tape, and the adsorption surface is provided with a plurality of suction holes.

[0027] The suction cup is hollow, with an air inlet and an air vent on the side opposite the suction surface. The suction port is connected to an external vacuum pump. The air vent prevents the suction cup from holding the tape too tightly, ensuring that the tape moves with the vacuum insulation panel. To achieve a better fit, the suction surface is cylindrical or arc-shaped.

[0028] In the above-mentioned tape applying device, a scraper is rotatably connected to the movable frame for preventing the tape from falling off the suction cup. The scraper has an anti-stick coating on the side facing the suction cup. The fixed frame is provided with a driving structure for driving the scraper to move to the bottom of the suction cup when the movable frame rises.

[0029] When the movable frame rises, the drive mechanism moves the scraper under the suction cup. The scraper's side facing the suction cup moves to the underside of the suction surface and faces it. The tape is trapped between the suction surface and the scraper's side facing the suction cup, working in conjunction with the suction holes to prevent the tape from falling off the suction cup. To better hold the tape in place, the scraper's side facing the suction cup is cylindrical or arc-shaped, matching the suction surface. When the movable frame descends, the scraper disengages from the suction cup and moves behind it.

[0030] In the above-mentioned tape applying device, the scraper includes a connecting part and a limiting part connected to the connecting part, and the end of the connecting part away from the limiting part is hinged to the movable frame; the driving structure includes a second connecting rod whose upper end is hinged to the fixed frame, and the lower end of the second connecting rod is hinged to the connecting part.

[0031] The front end of the connecting portion is hinged to the movable frame, and the stopper is located at the rear end of the connecting portion. An anti-stick coating is applied to the side of the stopper facing the suction cup (i.e., the front side). The rotational centerline of the connecting portion is parallel to the rotational centerline of the suction cup. When the movable frame rises, the front end of the connecting portion rises, and the second connecting rod causes the stopper to move downward. When the stopper moves below the suction cup, it prevents the tape from falling.

[0032] In the aforementioned tape applying device, the fixed frame includes a hinge bracket extending to the other side of the movable frame, and the upper end of the second connecting rod is hingedly connected to the hinge bracket. This arrangement allows the cutter bracket to be located on one side of the movable frame, while the connecting portion is located on the other side of the movable frame, thereby preventing interference between the cutter bracket and the connecting portion.

[0033] In the above-mentioned tape applying device, at least one tape idler wheel is provided on the movable frame, the axis of the tape idler wheel is parallel to the axis of the tape roll, and the tape drawn out from the tape roll passes around the tape idler wheel and extends to below the suction cup.

[0034] In the aforementioned tape-applying device, a base plate is positioned below the mounting plate and fixed relative to the mounting plate. The base plate has an opening in which a tape pressure roller extending in the left-right direction is mounted. The rotating shafts at both ends of the tape pressure roller are connected to the base plate via elastic supports. These supports are equipped with first elastic plungers for pressing the rotating shafts. The tape pressure roller is located in front of the suction cup, and the first elastic plunger acts to fully apply the tape to the vacuum insulation panel.

[0035] In the above-mentioned tape applying device, the frame has two first cross beams located above the conveying mechanism and extending in the left and right directions, each of the first cross beams is provided with two pressure roller brackets, and a pressure roller extending left and right is installed between the two pressure roller brackets located on the same first cross beam, and a second elastic plunger is installed on the pressure roller bracket, and the lower end of the second elastic plunger rests on the rotating shaft of the pressure roller.

[0036] The two guide rails are respectively located on different first cross beams, one of the pressing rollers is located in front of the bottom plate, and the other pressing roller is located behind the bottom plate. The packaging bags of the vacuum insulation panel can be further flattened by the pressing rollers.

[0037] In the above-mentioned adhesive tape applying device, a guide plate is provided behind the base plate, and the rear end of the guide plate has a guide portion extending upwardly and obliquely from front to back. The guide plate is connected to the base plate through a connecting frame located above the adhesive pressing roller.

[0038] In the above-mentioned tape applying device, the lower sides of the bottom plate and the guide plate are both provided with side ribs extending in the front-to-back direction.

[0039] The edge bars limit the left and right directions of the vacuum insulation panel.

[0040] In the above-mentioned tape applying device, the conveying mechanism includes two synchronous rollers extending in the left-right direction, a driving roller driven by a driving assembly, and a conveyor belt tensioned on the two synchronous rollers and the driving roller, and the driving roller is parallel to the synchronous roller.

[0041] The conveyor belt's section between the two synchronous rollers is the conveying section, which extends horizontally. During operation, the drive assembly rotates the active rollers, driving the conveying section of the conveyor belt forward, transporting the vacuum insulation panels on the conveying section forward.

[0042] In order to better support the conveying part, a conveying support plate parallel to the conveying part is provided below the conveying part, and the inner side surface of the conveyor belt (ie the lower surface of the conveying part) is slidably matched with the conveying support plate.

[0043] In the above-mentioned tape applying device, two baffles distributed in the left and right directions are provided on the frame, and the two ends of the two synchronous rollers are respectively rotatably cooperated with different baffles. Drive mounting plates are respectively provided under the two baffles, and the two ends of the active roller are respectively rotatably cooperated with different drive mounting plates.

[0044] In the aforementioned tape application device, the drive assembly includes a motor fixed to one of the drive mounting plates, a driving pulley mounted on the motor's rotating shaft, and a driven pulley mounted on the driving roller. The driving pulley and the driven pulley are connected by a belt drive. When the motor rotates, it drives the driving pulley, which in turn drives the driven pulley via the belt, thereby driving the driving roller, thereby achieving conveying of the conveyor belt.

[0045] In order to realize automatic control, a photoelectric sensor is set on the frame to sense the vacuum insulation panel. The photoelectric sensor is connected to the controller, and the controller outputs instructions to control the action of the driver.

[0046] Compared with the existing technology, the present tape applying device has the following advantages: the distance between the two tape machines can be adjusted by the drag chain to adapt to the tape applying of vacuum insulation panels of different widths; the height of the tape machine can be adjusted in real time by the vertical adjustment hand wheel to adapt to the tape applying of vacuum insulation panels of different thicknesses; the lateral position of the tape machine can be adjusted by the lateral adjustment hand wheel to achieve the tape applying of packaging bags of different widths on vacuum insulation panels of the same width; the pressing roller can further flatten the packaging bags of the vacuum insulation panels, and the cooperation of the scraper and the cutting assembly facilitates the adsorption of the cut tape to prevent the tape from falling off. After the tape is applied, the vacuum insulation panel can pass through the tape pressing wheel to completely apply the tape on the vacuum insulation panel; it replaces the manual taping operation method of the vacuum insulation panel in the existing technology, saves manpower, improves efficiency and reduces costs.

[0059] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0060] like Figure 1 and Figure 2 The taping device shown is used to apply tape to vacuum insulation panels, and includes a frame 1, a conveying mechanism provided on the frame 1 for conveying the vacuum insulation panels forward, and two tape dispensers provided on the frame 1 and located above the conveying mechanism. The two tape dispensers are distributed in the left and right directions. The frame 1 is also provided with a first adjustment mechanism for adjusting the left and right distance between the two tape dispensers.

[0061] In this embodiment, Figure 3 and Figure 4As shown, the conveying mechanism comprises two synchronous rollers 37 extending horizontally, a driving roller 38 driven by a drive assembly, and a conveyor belt 39 stretched across the two synchronous rollers 37 and the driving roller 38. The driving roller 38 is parallel to the synchronous rollers 37. The portion of the conveyor belt 39 between the two synchronous rollers 37 is the conveying section, which extends horizontally. During operation, the drive assembly rotates the driving rollers 38, thereby driving the conveying section of the conveyor belt 39 forward, transporting the vacuum insulation panels located on the conveying section.

[0062] In order to better support the conveying part, a conveying support plate 11 parallel to the conveying part is provided below the conveying part, and the inner side surface of the conveyor belt 39 (ie the lower surface of the conveying part) is slidably matched with the conveying support plate 11.

[0063] like Figure 3 As shown, the frame 1 is provided with two baffles 40 distributed along the left and right directions, and the two ends of the two synchronous rollers 37 are respectively rotated with different baffles 40. A drive mounting plate 41 is respectively provided under the two baffles 40, and the two ends of the active roller 38 are respectively rotated with different drive mounting plates 41. Figure 3 and Figure 4 As shown, the drive assembly includes a motor 42 fixed to one of the drive mounting plates 41, a driving wheel 43 provided on the rotating shaft of the motor 42, and a driven wheel 44 provided on the driving roller 38. The driving wheel 43 and the driven wheel 44 are connected to each other via a belt 45. When the motor 42 rotates, the driving wheel 43 is driven to rotate, and the driving wheel 43 drives the driven wheel 44 to rotate via the belt 45, thereby driving the driving roller 38 to rotate, thereby realizing the conveying of the conveyor belt 39.

[0064] In order to tighten the conveyor belt 39, Figure 3 and Figure 4 As shown, two tensioning pulleys are adjustably mounted between two drive mounting plates 41. The active roller 38 is located below the two tensioning pulleys. The conveyor belt 39 is wound around the synchronous roller 37 and the active pulley 43 and is tightened by the two tensioning pulleys. The tensioning pulleys are mounted between the two drive mounting plates 41 using existing adjustment structures.

[0065] like Figure 5As shown, the first adjustment mechanism includes a guide rail 2 extending in the left-right direction, a slide 3 provided on the guide rail 2 and slidingly engaged with the guide rail 2, and a locking structure 4 for locking the slide 3 to the guide rail 2, wherein one tape conveyor is fixed relative to the slide 3, and the other tape conveyor is fixed relative to the guide rail 2. When the left-right distance between the two tape conveyors needs to be adjusted, the locking structure 4 is first unlocked, and then the slide 3 is moved on the guide rail 2, driving the tape conveyor fixed relative to the slide 3 to move relative to the other tape conveyor. When the slide 3 is moved into place, the locking structure 4 is used to lock the slide 3 to the guide rail 2. The operation is convenient and is conducive to adjusting the left-right distance between the two tape conveyors. In this embodiment, the locking structure 4 is a clamp for the linear guide rail 2.

[0066] In some other embodiments, the first adjustment mechanism includes a guide rail 2 extending in the left-right direction, a slide 3 disposed on and slidably engaged with the guide rail 2, and a locking structure 4 for locking the slide 3 to the guide rail 2. The two tape dispensers are respectively fixed relative to different slides 3. This allows the positions of the two tape dispensers to be adjusted, providing greater flexibility.

[0067] like Figure 5 As shown, there are two guide rails 2 distributed in the front-to-back direction, and a slide 3 is slidably engaged with each guide rail 2. A mounting plate 5 is provided under each tape conveyor, wherein the front and rear ends of one mounting plate 5 are respectively fixedly connected to different guide rails 2, and the front and rear ends of the other mounting plate 5 are respectively fixedly connected to the slide 3 located on different guide rails 2.

[0068] To facilitate adjustment of the distance between the two mounting plates 5, they are connected by a drag chain 47. Electrical wires are installed within the drag chain 47 to control the movement of the tape conveyor, which is slidably connected to the guide rail 2. To adjust the distance, the locking mechanism 4 is unlocked, allowing the other mounting plate 5 to move along the guide rail 2. Once it is in place, the locking mechanism 4 secures it in place. Changing the distance between the two mounting plates 5 also changes the distance between the two tape conveyors. The mounting plates 5 provide support for the tape conveyor, improving its stability.

[0069] like Figure 5 and Figure 6 As shown, an upper cover plate 6 is positioned above each mounting plate 5, and the tape dispenser is mounted on the corresponding upper cover plate 6. A second adjustment mechanism for adjusting the height of the upper cover plate 6 is provided between the upper cover plate 6 and the mounting plate 5. The height of the tape dispenser can be adjusted by adjusting the height of the upper cover plate 6 via the second adjustment mechanism, enabling the tape dispenser to apply tape to vacuum insulation panels of varying thicknesses, thus providing a wide range of applications.

[0070] like Figure 6As shown, the second adjustment mechanism includes several guide rods 7 vertically fixed to the mounting plate 5, elastic sleeves 8 mounted on the guide rods 7, and threaded rods 9 with their lower ends threadedly connected to the mounting plate 5. The upper cover plate 6 is provided with through-holes corresponding to the guide rods 7 and the threaded rods 9. The upper ends of the guide rods 7 and the threaded rods 9 extend through the corresponding through-holes. The elastic sleeves 8 are positioned between the upper cover plate 6 and the mounting plate 5. The upper ends of the threaded rods 9 are fixedly connected to a vertical adjustment handwheel 10 that is pressed against the upper cover plate 6. Turning the vertical adjustment handwheel 10 rotates the threaded rods 9, causing them to rise and fall relative to the mounting plate 5, thereby driving the vertical adjustment handwheel 10 up and down. When the vertical adjustment handwheel 10 descends, it squeezes the upper cover plate 6, causing it to descend, lowering the tape conveyor with it and compressing the elastic sleeves 8. When the vertical adjustment handwheel 10 ascends, the elastic sleeves 8 return to their original position, causing the upper cover plate 6 to ascend, raising the tape conveyor with it. The elastic sleeves 8 can be constructed using a spring or other similar structure.

[0071] Alternatively, the second adjustment mechanism includes several screws that rotatably engage the mounting plate 5 and are threadedly connected to the upper cover 6. To prevent the upper cover 6 from rotating when the screws are turned, vertical guide posts are fixed to the mounting plate 5, with which the upper cover 6 slides. The screws are connected via a sprocket chain drive. When one screw rotates, the remaining screws rotate synchronously in the same direction. Rotating the screws causes the upper cover 6 to rise and fall.

[0072] like Figure 6 and Figure 7 As shown, two support plates 11 arranged opposite to each other in the left-right direction are fixed on the upper cover plate 6. An adjustment rod 12 extending in the left-right direction is inserted between the two support plates 11. The tape machine is located between the two support plates 11 and is threadedly connected to the adjustment rod 12. One end of the adjustment rod 12 is fixedly connected to a transverse adjustment handwheel 13. In order to prevent the tape machine from rotating circumferentially around the adjustment rod 12, a guide rod parallel to the adjustment rod 12 is provided between the two support plates 11, and the tape machine and the guide rod are slidably engaged. The adjustment rod 12 is rotatably connected to the support plates 11 respectively. When the adjustment rod 12 rotates, it drives the tape machine to move in the left-right direction, changing the lateral position of the tape machine in the left-right direction, thereby realizing the taping of packaging bags of different widths on the same width vacuum insulation panels, and ensuring that the side edges of the packaging bags are fixed to the upper surface of the vacuum insulation panels by the tape.

[0073] like Figure 8 and Figure 9As shown, the tape conveyor includes a fixed frame 14 disposed above and fixed relative to the conveyor belt 39, a movable frame 15 disposed opposite the fixed frame 14, a tape roll 16 disposed on the upper portion of the movable frame 15, a suction cup 17 disposed on the lower portion of the movable frame 15, and a driver 18 for driving the movable frame 15 up and down. The movable frame 15 is higher than the fixed frame 14. The driver 18 is fixed to the fixed frame 14, and the movable frame 15 is connected to the movable end of the driver 18. To facilitate the installation of the tape roll 16 on the movable frame 15, a rotating drum that can rotate about its own centerline is disposed on the upper portion of the movable frame 15. The tape roll 16 is coaxially sleeved on the rotating drum and tightly fits the rotating drum.

[0074] like Figure 11 As shown, the actuator 18 comprises a cylinder body secured to the fixed frame 14, with the movable frame 15 securely connected to the piston rod of the cylinder body. The cylinder body is a pneumatic or hydraulic cylinder, but in this embodiment, it is an inverted cylinder, with the piston rod extending from the lower end. Extending the piston rod lowers the mounting frame. Retracting the piston rod raises the mounting frame.

[0075] like Figure 8-11 As shown, suction cup 17 is rotatably connected to movable frame 15, with its rotational centerline extending horizontally along the width of conveyor belt 39 and parallel to the axis of tape roll 16. The tape drawn from tape roll 16 passes over suction cup 17 and, under its pressure, adheres to the vacuum insulation panel below. A cutting assembly is provided between movable frame 15 and fixed frame 14, which is used to sever the tape between suction cup 17 and the vacuum insulation panel when movable frame 15 is raised.

[0076] The vacuum insulation panel is positioned on a conveyor belt 39 and is conveyed forward by the conveyor belt 39. The back of the tape, drawn from the tape roll 16, passes over the suction cup 17 from top to bottom and from back to front. Under the pressure of the suction cup 17, the adhesive surface of the tape adheres to the upper surface of the vacuum insulation panel. As the vacuum insulation panel is conveyed forward, the tape is continuously pulled forward and adheres to the vacuum insulation panel, achieving the purpose of automatically adhering the tape to the vacuum insulation panel.

[0077] After the pasting is completed, the driver 18 drives the movable frame 15 to rise, so that the suction cup 17 is separated from the pressure on the vacuum insulation panel, and then the straightened tape between the suction cup 17 and the vacuum insulation panel is cut off under the action of the cutting component.

[0078] like Figure 8 and Figure 10 As shown, three tape idlers 26 are provided on the movable frame 15. The three tape idlers 26 are arranged in sequence from top to bottom. The axis of the tape idler 26 is parallel to the axis of the tape roll 16. The tape led out from the tape roll 16 passes around the tape idler 26 and extends to the bottom of the suction cup 17.

[0079] The lower part of the suction cup 17 has an adsorption surface 22 in contact with the tape, and a plurality of suction holes are provided on the adsorption surface 22. Figure 1 The structure of the middle suction cup 17. The suction cup 17 is hollow, with an air inlet and an air inlet located on the upper side (opposite to the suction surface 22). The air inlet is connected to an external vacuum device. The air inlet effectively prevents the suction cup 17 from holding the tape too tightly, ensuring that the tape moves with the vacuum insulation panel. To achieve a better fit, the suction surface 22 is cylindrical or arc-shaped.

[0080] like Figure 10 As shown, a scraper 23 is rotatably connected to the movable frame 15 for preventing the tape from falling off the suction cup 17. The scraper 23 has an anti-stick coating on the side facing the suction cup 17. The fixed frame 14 is provided with a driving structure for driving the scraper 23 to move to the bottom of the suction cup 17 when the movable frame 15 rises.

[0081] When the movable frame 15 rises, the drive mechanism causes the scraper 23 to move below the suction cup 17. At this point, the side of the scraper 23 facing the suction cup 17 moves to the underside of the suction surface 22 and faces the suction surface 22. The adhesive tape is trapped between the suction surface 22 and the side of the scraper 23 facing the suction cup 17, and the suction force of the suction holes prevents the tape from falling off the suction cup 17. To better retain the tape, the side of the scraper 23 facing the suction cup 17 is cylindrical or arc-shaped, matching the suction surface 22. When the movable frame 15 descends, the scraper 23 disengages from the suction cup 17 and moves behind it.

[0082] Specifically, such as Figure 10 As shown, the scraper 23 includes an integrally formed connecting portion and a limiting portion, and the end of the connecting portion away from the limiting portion is hinged to the movable frame 15. The driving structure includes a second connecting rod 24 whose upper end is hinged to the fixed frame 14 and whose lower end is hinged to the connecting portion.

[0083] The front end of the connecting portion is hingedly connected to the movable frame 15, and the stopper is located at the rear end of the connecting portion. An anti-stick coating is applied to the side of the stopper facing the suction cup 17 (i.e., the front side). The rotational centerline of the connecting portion is parallel to the rotational centerline of the suction cup 17. When the movable frame 15 rises, the front end of the connecting portion rises, and the second connecting rod 24 causes the stopper to move downward. When the stopper moves below the suction cup 17, it prevents the paper tape from falling.

[0084] like Figure 8 As shown, the cutting assembly includes a cutter bracket 19 rotatably connected to the movable frame 15, a cutting portion provided at the free end of the cutter bracket 19, and a first connecting rod 21 whose upper end is rotatably connected to the fixed frame 14, and the lower end of the first connecting rod 21 is hinged to the cutter bracket 19.

[0085] The rotation centerline of the cutter bracket 19 is parallel to the rotation centerline of the first connecting rod 21 and to the rotation centerline of the suction cup 17. The rotation centerline of the cutter bracket 19 is located at the rear end of the cutter bracket 19 and above the rotation centerline of the suction cup 17. The cutting portion is located at the front end of the cutter bracket 19. The lower end of the first connecting rod 21 is hinged to the end of the cutter bracket 19 near the cutting portion. When the movable frame 15 rises, it drives the rear end of the cutter bracket upward. Since the upper end of the first connecting rod 21 is fixed in position, the front end of the cutter bracket 19 swings downward about the rotation centerline under the support of the first connecting rod 21, driving the cutting portion downward to contact and cut the tape between the suction cup 17 and the vacuum insulation panel.

[0086] In this embodiment, Figure 9 As shown, the cutting part is a heating wire, and two heating wire seats are set at the front end of the cutter bracket 19. The heating wire is stretched between the two heating wire seats, and the heating wire is parallel to the rotation center line of the cutter bracket 19.

[0087] like Figure 10 As shown, the fixed frame 14 has a hinge bracket 25 extending to the other side of the movable frame 15, and the upper end of the second connecting rod 24 is hinged to the hinge bracket 25. The cutter bracket 19 and the connecting portion are located on different sides of the movable frame 15 to avoid interference between the cutter bracket 19 and the connecting portion.

[0088] In some other embodiments, such as Figure 8 As shown, the cutting portion is a cutter. The cutter is perpendicular to the cutter support 19, and the extension direction of the cutter edge is parallel to the rotation center line of the cutter support 19. In order to effectively cut the tape, the cutter edge is composed of multiple teeth, each of which has a sharp tooth tip.

[0089] like Figure 6 As shown, a base plate 27 is fixed relative to the mounting plate 5 below the mounting plate 5. Base plate 27 has an opening in which a tape pressure roller 28 extending horizontally is mounted. The rotating shafts at both ends of the tape pressure roller 28 are connected to the base plate 27 via elastic supports 29. The elastic supports 29 are mounted with first elastic plungers for pressing the rotating shafts. The tape pressure roller 28 is located in front of the suction cup. The first elastic plunger ensures that the tape is fully applied to the vacuum insulation panel.

[0090] Openings are provided on both the mounting plate 5 and the bottom plate 27, and the lower portion of the adhesive tape machine is located in the openings.

[0091] like Figure 2 As shown, the frame 1 has two first crossbeams 30 located above the conveying mechanism and extending in the left-right direction, and each first crossbeam 30 is provided with two pressure roller brackets 31, as shown in FIG. Figure 5As shown, a left-right extending glue roller 32 is mounted between two pressure roller brackets 31 located on the same first crossbeam 30. A second elastic plunger is mounted on the pressure roller bracket 31, the lower end of which abuts against the rotating shaft of the glue roller 32. The two guide rails 2 are located on different first crossbeams 30, with one glue roller 32 located in front of the bottom plate 27 and the other behind it. The glue rollers 32 can further flatten the packaging bags of the vacuum insulation panel.

[0092] like Figure 5 and Figure 6 As shown, a guide plate 33 is provided at the rear of the bottom plate 27 , and a rear end of the guide plate 33 has a guide portion 34 extending upward from the front to the rear. The guide plate 33 is connected to the bottom plate 27 via a connecting frame 35 located above the rubber pressing roller 32 .

[0093] like Figure 5 and Figure 6 As shown, the bottom side of the bottom plate 27 and the guide plate 33 are both provided with a rib 36 extending in the front-back direction. The rib 36 limits the left-right direction of the vacuum insulation panel.

[0094] Also includes control systems, such as Figure 1 As shown, the control system includes a photoelectric sensor 46, an electric control cabinet, and a controller installed in the electric control cabinet; the photoelectric sensor 46 is used to sense the vacuum insulation panel, the photoelectric sensor 46 is connected to the controller, and the controller outputs instructions to control the action of the driver.

[0095] During operation, the motor 42 rotates, driving the conveyor belt 39 and placing the vacuum insulation panel on it. When the photoelectric sensor detects the vacuum insulation panel, it outputs an electrical signal to the controller, which in turn instructs the cylinder's piston rod to extend. The vacuum insulation panel passes over the adhesive roller 32 located at the rear, further flattening the packaging bag within the panel. The cylinder drives the movable frame downward, and the suction cup contacts the packaging bag, causing the tape to adhere to the packaging bag. When the end of the vacuum insulation panel leaves the working space of the photoelectric sensor, the photoelectric sensor outputs an electrical signal to the controller, and the controller outputs an instruction to control the piston rod of the cylinder to contract, and the cutting component works, cutting the tape through the cutting part. At the same time, the scraper rotates, and the rotation direction is opposite to the rotation direction of the cutter bracket, so that the scraper rotates toward the suction cup, so that the suction cup can absorb the cut tape and prevent the tape from falling. After the tape is applied, the vacuum insulation panel passes through the tape pressing wheel 28 in the front to completely apply the tape on the vacuum insulation panel, and is further flattened by the glue pressing roller 32 in the front to obtain the finished product.

[0096] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
