Description

Technical Field

[0001] This invention belongs to the field of tape machine technology and relates to a tape machine for applying tape. Background Technology

[0002] Vacuum insulation panels are a type of high-efficiency thermal insulation material that combines the principles of vacuum insulation with traditional insulation materials. They are manufactured using fiberglass as the core material and an air-barrier composite film as the encapsulation bag, after being vacuum-sealed. Because they maximize the vacuum level within the panel and reduce gas convection, they achieve highly efficient insulation. Compared to other materials, vacuum insulation panels, with their extremely low thermal conductivity, offer advantages such as thinner insulation layer, smaller volume, and lighter weight while maintaining the same insulation requirements. They are suitable for products with high energy-saving requirements and have significant technical and economic value.

[0003] In the production of vacuum insulation panels, tape needs to be applied to both sides of the folded vacuum insulation panel. In the current technology, the tape is usually applied manually, which is inefficient and the accuracy of manual application is not high, which easily leads to a large number of defective products. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a highly efficient and effective tape applicator.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A tape applicator includes a fixed frame, a movable frame opposite to the fixed frame, a tape roll on the movable frame, and a suction cup on the movable frame. The rotation center line of the suction cup is parallel to the axis of the tape roll. The tape drawn from the tape roll passes around the suction cup and is adhered to a substrate located below, specifically a vacuum insulation board, under the pressure of the suction cup. A cutting component is provided between the movable frame and the fixed frame to cut the tape located between the suction cup and the vacuum insulation board when the movable frame is raised.

[0007] The tape conveyor is positioned above the conveyor belt, with the vacuum insulation panel located on the belt and conveyed forward. The driver is fixed to a fixed frame, and a suction cup is rotatably connected to a movable frame, its rotational centerline extending horizontally along the width of the conveyor belt. The back side of the tape, drawn from the tape roll, wraps around the suction cup from top to bottom and back to front. Under the pressure of the suction cup, the adhesive side 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 tape adhesion. After adhesion is complete, the driver raises the movable frame, releasing the suction cup from the vacuum insulation panel. Subsequently, the cutting component cuts the taut tape located between the suction cup and the vacuum insulation panel.

[0008] In the tape machine for applying tape described above, the cutting assembly includes a cutter bracket rotatably connected to a movable frame, a cutting part disposed at the free end of the cutter bracket, and a first connecting rod rotatably connected at its upper end to a fixed frame, the lower end of the first connecting rod being hinged to the cutter bracket.

[0009] The rotation centerline of the cutter holder is parallel to the rotation centerline of the first connecting rod and also parallel to the rotation centerline of the suction cup. The rotation centerline of the cutter holder is located at the rear end of the cutter holder and above the rotation centerline of the suction cup, while the cutting part is located at the front end of the cutter holder. The lower end of the first connecting rod is hinged to the end of the cutter holder near the cutting part. When the movable frame rises, it causes the rear end of the cutter holder to rise. Since the upper end of the first connecting rod is fixed, under the support of the first connecting rod, the front end of the cutter holder swings downward around the rotation centerline, causing the cutting part to contact and cut the tape located between the suction cup and the vacuum insulation plate.

[0010] In the tape applicator described above, the cutting part is a cutter. The cutter is perpendicular to the cutter holder, and the extending direction of the cutter blade is parallel to the rotation centerline of the cutter holder. In order to effectively cut the tape, the cutter blade consists of multiple teeth, each with a sharp tip.

[0011] In the tape applicator described above, the cutting part is a heating wire. Two heating wire holders are provided at the front end of the cutter bracket, and the heating wire is stretched between the two heating wire holders. The heating wire is parallel to the rotation centerline of the cutter bracket.

[0012] In the tape applicator described above, the lower part of the suction cup has an adsorption surface that contacts the tape, and the adsorption surface is provided with a plurality of suction holes.

[0013] The suction cup is hollow inside, with an air intake and an air inlet on the side opposite the suction surface. The air intake connects to an external air extraction device, and the air inlet effectively prevents the suction cup from gripping the tape too tightly, ensuring that the tape can move with the vacuum insulation panel. For better adhesion, the suction surface is cylindrical or curved.

[0014] In the tape applicator described above, a scraper is rotatably connected to the movable frame to prevent 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 drive structure for driving the scraper to move below the suction cup when the movable frame is raised.

[0015] As the movable frame rises, the drive mechanism moves the scraper below the suction cup. At this point, the scraper's side facing the suction cup moves to the underside of the suction surface and is positioned opposite it. The tape is contained between the suction surface and the scraper's side facing the suction cup, and the suction force of the suction holes prevents the tape from falling off the suction cup. To better contain the tape, the scraper's side facing the suction cup is cylindrical or curved, aligning with the suction surface. When the movable frame descends, the scraper detaches from the suction cup and moves behind it.

[0016] In the tape applicator described above, the scraper includes a connecting part and a limiting part connected to the connecting part, and one end of the connecting part away from the limiting part is hinged to the movable frame; the drive structure includes a second connecting rod with its upper end hinged to the fixed frame, and the lower end of the second connecting rod is hinged to the connecting part.

[0017] The front end of the connecting part is hinged to the movable frame, and the limiting part is located at the rear end of the connecting part. An anti-stick coating is applied to the limiting part on the side facing the suction cup (i.e., the front side). The rotation centerline of the connecting part is parallel to the rotation centerline of the suction cup. When the movable frame rises, it causes the front end of the connecting part to rise, and under the action of the second connecting rod, the limiting part moves downwards. When the limiting part moves below the suction cup, it serves to prevent the paper tape from falling off.

[0018] In the aforementioned tape applicator, the fixed frame has a hinge bracket extending to the other side of the movable frame, and the upper end of the second connecting rod is hinged to the hinge bracket. This arrangement aims to position the cutter bracket on one side of the movable frame and the connecting part on the other side, thus preventing interference between the cutter bracket and the connecting part.

[0019] In the tape applicator described above, the fixed frame is equipped with a driver for driving the movable frame to move up and down, and the driver is a linear driver.

[0020] In the tape applicator described above, the driver includes a cylinder fixed on a fixed frame, and the movable frame is fixedly connected to the piston rod of the cylinder.

[0021] The cylinder body is either a pneumatic cylinder or a hydraulic cylinder, preferably a pneumatic cylinder. The cylinder body is inverted, with the piston rod extending from the lower end of the cylinder body. When the piston rod extends, it lowers the mounting bracket; when the piston rod retracts, it raises the mounting bracket.

[0022] In the tape applicator described above, the movable frame is provided with at least one tape idler wheel. The axis of the tape idler wheel is parallel to the axis of the tape roll. The tape drawn from the tape roll passes around the tape idler wheel and extends to below the suction cup.

[0023] Compared with existing technologies, this tape applicator has the following advantages: it can automatically apply tape to both sides of the folded vacuum insulation board, replacing the manual operation method in existing technologies, so as to improve the quality of vacuum insulation boards, save manpower, increase efficiency and reduce costs.

Detailed Implementation

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] Example 1

[0031] like Figure 2 and Figure 3 The tape applicator shown is used to apply tape to vacuum insulation panels. It includes a fixed frame 1 positioned above and fixed relative to the conveyor belt, a movable frame 2 positioned opposite the fixed frame 1, a tape roll 3 located on the upper part of the movable frame 2, a suction cup 4 located on the lower part of the movable frame 2, and a driver 5 for driving the movable frame 2 to move up and down. The movable frame 2 is higher than the fixed frame 1. The driver 5 is fixed to the fixed frame 1, and the movable frame 2 is connected to the movable end of the driver 5. To facilitate the installation of the tape roll 3 onto the movable frame 2, a rotating drum that can rotate around its own centerline is provided on the upper part of the movable frame 2. The tape roll 3 is coaxially sleeved on the rotating drum and tightly fitted with it.

[0032] like Figure 4As shown, the actuator 5 includes a cylinder body fixed to the fixed frame 1, and the movable frame 2 is fixedly connected to the piston rod of the cylinder body. The cylinder body is a pneumatic cylinder or a hydraulic cylinder; in this embodiment, it is a pneumatic cylinder. The cylinder body is inverted, and the piston rod extends from the lower end of the cylinder body. When the piston rod extends, it drives the mounting frame to descend. When the piston rod retracts, it drives the mounting frame to rise.

[0033] like Figure 2-4 As shown, the suction cup 4 is rotatably connected to the movable frame 2, and its rotation centerline extends horizontally along the width direction of the conveyor belt, with the rotation centerline of the suction cup 4 parallel to the axis of the tape roll 3. The tape led from the tape roll 3 passes around the suction cup 4 and is adhered to the vacuum insulation plate located below under the pressure of the suction cup 4. A cutting assembly is provided between the movable frame 2 and the fixed frame 1 to cut the tape located between the suction cup 4 and the vacuum insulation plate when the movable frame 2 rises.

[0034] The vacuum insulation panel is located on a conveyor belt and is conveyed forward by the conveyor belt. The back side of the tape led from tape roll 3 passes around suction cup 4 from top to bottom and from back to front. Under the pressure of suction cup 4, the adhesive side of the tape is adhered to the upper surface of the vacuum insulation panel. As the vacuum insulation panel is conveyed forward, the tape is continuously pulled forward and continuously adhered to the vacuum insulation panel, thus achieving the purpose of automatically adhering the tape to the vacuum insulation panel.

[0035] After the adhesive is applied, the driver 5 drives the movable frame 2 to rise, causing the suction cup 4 to release its pressure on the vacuum insulation board. Then, under the action of the cutting component, the straightened tape located between the suction cup 4 and the vacuum insulation board is cut.

[0036] like Figure 2 and Figure 4 As shown, the movable frame 2 is equipped with three tape idler wheels 16, which are arranged sequentially from top to bottom. The axis of the tape idler wheel 16 is parallel to the axis of the tape roll 3. The tape led out from the tape roll 3 passes around the tape idler wheel 16 and extends to the bottom of the suction cup 4.

[0037] The lower part of the suction cup 4 has an adsorption surface 11 that contacts the tape. The adsorption surface 11 is provided with several suction holes, and its structure is referenced. Figure 1 The structure of the suction cup 4: The suction cup 4 is hollow inside, and has an air intake and an air inlet on the side (upper side) opposite to the adsorption surface 11. The air intake is connected to an external air extraction device. The air inlet effectively prevents the suction cup 4 from adsorbing the tape too tightly, ensuring that the tape can move together with the vacuum insulation plate. To achieve better adhesion, the adsorption surface 11 is a cylindrical or arc-shaped surface.

[0038] like Figure 3 As shown, a scraper is rotatably connected to the movable frame 2 to prevent the tape from falling off the suction cup 4. The scraper has an anti-stick coating on the side facing the suction cup 4. The fixed frame 1 is provided with a drive structure for driving the scraper to move below the suction cup 4 when the movable frame 2 rises.

[0039] When the movable frame 2 rises, the drive structure moves the scraper to below the suction cup 4. At this time, the scraper moves to the side facing the suction cup 4 and is positioned opposite to the suction surface 11. The tape is confined between the suction surface 11 and the side of the scraper facing the suction cup 4, and the suction force of the suction hole prevents the tape from falling off the suction cup 4. To better confine the tape, the side of the scraper facing the suction cup 4 is a cylindrical or arc-shaped surface, which cooperates with the suction surface 11. When the movable frame 2 descends, the scraper disengages from the suction cup 4 and moves to the rear of the suction cup 4.

[0040] Specifically, such as Figure 3 As shown, the scraper includes an integrally formed connecting part 12 and a limiting part 13, with one end of the connecting part 12 away from the limiting part 13 hinged to the movable frame 2. The drive structure includes a second connecting rod 14 with its upper end hinged to the fixed frame 1, and the lower end of the second connecting rod 14 hinged to the connecting part 12.

[0041] The front end of the connecting part 12 is hinged to the movable frame 2, and the limiting part 13 is located at the rear end of the connecting part 12. An anti-stick coating is applied to the side of the limiting part 13 facing the suction cup 4 (i.e., the front side). The rotation centerline of the connecting part 12 is parallel to the rotation centerline of the suction cup 4. When the movable frame 2 rises, it causes the front end of the connecting part 12 to rise, and under the action of the second connecting rod 14, the limiting part 13 moves downwards. When the limiting part 13 moves below the suction cup 4, it serves to prevent the paper tape from falling off.

[0042] like Figure 2 As shown, the cutting assembly includes a cutter bracket 6 rotatably connected to the movable frame 2, a cutting part located at the free end of the cutter bracket 6, and a first connecting rod 7 rotatably connected to the fixed frame 1 at its upper end. The lower end of the first connecting rod 7 is hinged to the cutter bracket 6.

[0043] The rotation centerline of the cutter bracket 6 is parallel to the rotation centerline of the first connecting rod 7 and also parallel to the rotation centerline of the suction cup 4. The rotation centerline of the cutter bracket 6 is located at its rear end and above the rotation centerline of the suction cup 4, while the cutting part is located at its front end. The lower end of the first connecting rod 7 is hinged to the end of the cutter bracket 6 near the cutting part. When the movable frame 2 rises, it drives the rear end of the cutter bracket 8 to rise. Since the upper end of the first connecting rod 7 is fixed, under the support of the first connecting rod 7, the front end of the cutter bracket 6 swings downward around the rotation centerline, causing the cutting part to contact and cut the tape located between the suction cup 4 and the vacuum insulation plate.

[0044] In this embodiment, as Figure 2 and Figure 3 As shown, the cutting part is a heating wire 9. Two heating wire seats 10 are provided at the front end of the cutter support 6. The heating wire 9 is stretched between the two heating wire seats 10. The heating wire 9 is parallel to the rotation center line of the cutter support 6.

[0045] like Figure 3 As shown, the fixed frame 1 has a hinge bracket 15 extending to the other side of the movable frame 2, and the upper end of the second connecting rod 14 is hinged to the hinge bracket 15. The cutter bracket 6 and the connecting part 12 are located on different sides of the movable frame 2 to avoid interference between the cutter bracket 6 and the connecting part 12.

[0046] Example 2

[0047] The structural principle of this embodiment is basically the same as that of Embodiment 1, except that, as Figure 1 As shown, the cutting part is a cutter 8. The cutter 8 is perpendicular to the cutter support 6, and the extension direction of the cutting edge of the cutter 8 is parallel to the rotation center line of the cutter support 6. In order to effectively cut the tape, the cutting edge of the cutter 8 is composed of multiple blades, each of which has a sharp tip.

[0048] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
