Description

Technical Field

[0001] This utility model relates to the technical field of tape processing, and in particular to a tape bonding device that can prevent the formation of air bubbles. Background Technology

[0002] In industrial production, wide-width adhesive tapes are widely used in packaging, construction, electronics, and other industries due to their efficient covering power and strong adhesive properties. They are commonly used to bond, fix, or wrap various materials. These tapes are typically produced using polypropylene film as a base material, with a special adhesive evenly coated on its surface, followed by lamination with a release film to ultimately create a product with specific adhesion and performance characteristics.

[0003] Currently, when laminating polypropylene film and release film, a cylinder-driven pressure plate is typically used for the pressing operation. While this method offers advantages such as ease of operation and controllable cost, the cylinder-driven pressure plate performs a single pressing operation, and the pressing process is rapid, making it difficult to completely expel air. This can easily lead to the formation of air bubbles between the two film layers, which may reduce their adhesive performance and physical strength. Utility Model Content

Detailed Implementation

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The tape bonding device for preventing air bubble formation according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the tape bonding device for preventing air bubbles according to this embodiment of the present invention may include a base 10, a drive assembly 30, a pressing assembly 40, two movable adjustment assemblies 60, and two pressing assemblies 70. The base 10 has supports 11 on both sides of its top surface, and each of the two supports 11 has a vertical plate 12 on its top surface. A guide rod 21 is provided between the two vertical plates 12, and a sliding sleeve 22 is slidably connected to the guide rod 21. A cylinder 23 is provided at the bottom end of the sliding sleeve 22, and a mounting frame 24 is connected to the piston end of the cylinder 23. A pressure roller 25 is rotatably disposed within the mounting frame 24. The drive assembly 30 is disposed on one side of the vertical plate 12 and is connected to the sliding sleeve 22. The pressing assembly 40 is disposed on one side of the mounting frame 24 and is connected to a scraper 50. The two movable adjustment assemblies 60 are disposed opposite each other on the base 10, and the two pressing assemblies 70 are respectively disposed on the two movable adjustment assemblies 60.

[0023] Specifically, the staff first attaches the release film of the wide tape to the polypropylene film coated with glue, then places the film and release film on the base 10, and then activates the two moving adjustment components 60 to adjust the distance between the two pressing components 70 so that the two pressing components 70 press and fix the two sides of the film and release film respectively.

[0024] Then, the drive assembly 30 is activated, causing the sliding sleeve 22 to move on the guide rod 21, so that the pressure roller 25 moves above the edge of the film and release film. Then, the cylinder 23 is activated, causing the pressure roller 25 to move downward, so that the pressure roller 25 adheres to the release film and the scraper 50 adheres to the base surface. Subsequently, the drive assembly 30 is activated, causing the sliding sleeve 22 to move on the guide rod 21, so that the pressure roller 25 and the scraper 50 move. The pressure roller 25 rolls on the release film, pressing the film and the release film together, so that the air between the film and the release film is gradually squeezed towards the edge. Under the action of the extrusion assembly 40, the scraper 50 adheres to the surface of the release film for further extrusion. This process is repeated, so that the pressure roller 25 rolls back and forth on the release film and the scraper 50 moves back and forth on the release film until the air bubbles between the film and the release film are eliminated.

[0025] The tape bonding device of this utility model, which can prevent the generation of air bubbles, can effectively eliminate air bubbles generated on the bonding surface during the tape bonding process through the coordinated reciprocating motion of the pressure roller and the scraper, thereby improving the adhesive performance and physical strength of the tape.

[0026] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the drive assembly 30 may include a support plate 31, a driver 32, a turntable 33, and a connecting rod 34. The support plate 31 is disposed on one side of the upright plate 12, the driver 32 is disposed on the support plate 31, the turntable 33 is connected to the output end of the driver 32, the upright plate 12 has a through hole 13, one end of the connecting rod 34 is hinged to the turntable 33, and the other end of the connecting rod 34 passes through the through hole 13 and is hinged to the sliding sleeve 22.

[0027] It should be noted that the driver 32 described in this embodiment can be a motor. The driver 32 can drive the turntable 33 to rotate, thereby driving the connecting rod 34 to move, which in turn pushes the sliding sleeve 22 to move horizontally on the guide rod 21, so that the pressure roller 25 rolls on the film to be bonded and the release film.

[0028] In one embodiment of this utility model, such as Figure 3As shown, the extrusion assembly 40 may include a connecting plate 41, a plurality of slide rods 42, a plurality of springs 43, and a plurality of limiting plates 44. The connecting plate 41 is disposed on one side of the mounting bracket 24. The plurality of slide rods 42 are slidably connected to the connecting plate 41, the bottom ends of the plurality of slide rods 42 are respectively connected to the scraper 50, and the top ends of the plurality of slide rods 42 are respectively connected to the corresponding limiting plates 44. The plurality of springs 43 are respectively disposed between the connecting plate 41 and the scraper 50, and the plurality of springs 43 are respectively sleeved on the corresponding slide rods 42.

[0029] It should be noted that the spring 43 can provide a squeezing effect on the scraper 50, thereby keeping the scraper 50 always in contact with the surface of the release film. Subsequently, the scraper 50 follows the pressure roller 25 to further press the release film and eliminate air bubbles. The movement range of the scraper 50 can be limited by setting the limiting plate 44.

[0030] In one embodiment of this utility model, such as Figure 4 As shown, the movable adjustment assembly 60 may include a fixed plate 61, an electric push rod 62, and a movable frame 63. The fixed plate 61 is mounted on the base 10, the electric push rod 62 is mounted on one side of the fixed plate 61, and the movable frame 63 is connected to the piston end of the electric push rod 62.

[0031] It should be noted that the position of the movable frame 63 can be adjusted by controlling the extension and retraction of the piston end of the electric push rod 62, thereby adjusting the distance between the two movable frames 63 to accommodate the size of the film and release film.

[0032] In one embodiment of this utility model, such as Figure 4 As shown, the clamping assembly 70 may include multiple vertical rods 71, a pressure plate 72, multiple clamping springs 73, and a handle 74. The multiple vertical rods 71 ​​are slidably connected to the movable frame 63, the pressure plate 72 is connected to the multiple vertical rods 71, the multiple clamping springs 73 are respectively disposed between the movable frame 63 and the pressure plate 72, and the multiple clamping springs 73 are respectively sleeved on the corresponding vertical rods 71. The handle 74 is connected to the multiple vertical rods 71.

[0033] It should be noted that when the film and release film need to be bonded, the worker first pulls the handle 74, which moves the pressure plate 72 upward, so that the two sides of the film and release film are respectively below the two pressure plates 72. Then, the handle 74 is released, and under the squeezing action of the compression spring 73, the two pressure plates 72 press and fix the two sides of the film and release film respectively.

[0034] In summary, the tape bonding device of this utility model, which can prevent the generation of air bubbles, can effectively eliminate air bubbles generated on the bonding surface during the tape bonding process through the coordinated reciprocating motion of the pressure roller and the scraper, thereby improving the adhesive performance and physical strength of the tape.
