Description

Technical Field

[0001] The utility model relates to the technical field of tape gluing, in particular to a transparent tape gluing device. Background Art

[0002] A transparent tape, a multifunctional adhesive tape with a BOPP film as the base material and coated with a pressure-sensitive adhesive, has been widely used in daily life and industrial fields for various purposes such as protection, fixation, and sealing since its invention by Richard Drew in 1928. Its characteristics include good transparency, high strength, and moderate adhesiveness, and it also has a relatively low cost, making it a more common and convenient tool. Due to its unique material and coating characteristics, the application of transparent tape is very extensive, mainly including two aspects: protection and fixation. In terms of protection, it can provide surface protection for products, preventing dust, oil, moisture, water, theft, etc., and can make the packaged items bear force evenly to avoid damage. In terms of fixation, due to its strong adhesiveness, it is not easy to burst when opening the box and is not easy to deform when squeezed.

[0003] However, before gluing some existing transparent tapes, no effective cleaning treatment is carried out on the transparent tapes. Due to the lack of a cleaning process, pollutants such as dust, oil stains, or fingerprints that may exist on the tape surface will directly contact the glue. This may not only reduce the bonding force of the glue but also damage the transparency and aesthetics of the tape due to the intervention of impurities. During the transmission process, it also does not have the function of adjusting the tape tension. Improper tension may cause various problems. For example, if the tape is too loose, it may produce wrinkles or offsets during gluing, resulting in uneven coating; on the contrary, if the tape is too tight, it may generate excessive tension during transmission, which may cause the tape to stretch and become thinner, affecting its physical properties and service life. Therefore, in view of the above deficiencies, a transparent tape gluing device is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a transparent tape gluing device, aiming to improve the problem that some tapes are not cleaned during the gluing process in the prior art.

[0034] Referring to Figures 2 to 4, there are pressing rollers 10 rotatably connected to the outside of both fixed shafts 9. The pressing rollers 10 are used to ensure that the tape remains flat during transportation, preventing wrinkling or deviation. There are inclined scrapers 8 rotatably connected to the outside of both pressing rollers 10. The inclined design of the inclined scrapers 8 helps to remove dust or impurities on the tape surface, keeping the tape clean, thereby ensuring the gluing quality. A pushing assembly for transmitting power is provided on the front side of the outer frame 1. The pushing assembly includes a mounting plate 11. The rear side of the mounting plate 11 is fixedly connected to the front side of the outer frame 1. A first cylinder 12 is installed on the left side of the mounting plate 11. The driving end of the first cylinder 12 is fixedly connected to a first push rod 13. The left side of the first push rod 13 is fixedly connected to a sliding block 14. The first cylinder 12 serves as a power source and drives the subsequent structure to displace through the first push rod 13 and the sliding block 14. A connecting shaft 15 is fixedly connected to the rear side of the pushing assembly. Both the front and rear sides of the connecting shaft 15 are rotatably connected to a rotating plate 16. The top of both rotating plates 16 is rotatably connected to a rotating sleeve 17. A connecting rod 18 is rotatably connected inside both rotating sleeves 17. A tensioning roller 19 is fixedly connected to the outside of the connecting rod 18. The tensioning roller 19 slides in the arc-shaped groove 20 along with the connecting rod 18 to achieve tensioning of the tape. Arc-shaped grooves 20 are provided on both the front and rear sides inside the outer frame 1. The outside of the connecting rod 18 is slidably connected inside the arc-shaped groove 20.

[0035] Referring to Figures 4 to 6 , a top frame 23 is fixedly connected to the top of the outer frame 1. A fixed frame 24 is fixedly connected to the middle side of the top of the outer frame 1. A second cylinder 25 is fixedly connected to the bottom of the top frame 23. The driving end of the second cylinder 25 is fixedly connected to a second push rod 26. The bottom of the second push rod 26 is fixedly connected to a connecting plate 27. Sealing rollers 28 are fixedly connected to both the left and right sides of the bottom of the connecting plate 27. The second cylinder 25 drives the sealing rollers 28 to move up and down through the second push rod 26 and the connecting plate 27 to control the flow rate and pressure of the glue. A plurality of flow channels 29 are provided on the bottom side inside the fixed frame 24. A plurality of brushes 30 are fixedly connected to the bottom of the fixed frame 24. The brushes 30 are responsible for evenly applying the glue on the tape. A second motor 31 is fixedly connected to the front side of the outer frame 1. The output end of the second motor 31 is fixedly connected to a driving shaft 32. A winding roller 33 is fixedly connected to the outside of the driving shaft 32. The second motor 31 serves as the power source of the winding assembly and drives the winding roller 33 to rotate through the driving shaft 32. The winding roller 33 is responsible for winding up the glued tape for subsequent processing or storage. A feeding groove 34 is provided on the bottom side inside the outer frame 1. The feeding groove 34 serves as the channel for the transparent tape to enter the device, ensuring that the tape smoothly enters the gluing area.

[0036] Working principle: When it is necessary to apply glue to the transparent tape, the transparent tape can be passed through the feeding groove 34. Subsequently, the first cylinder 12 can be started. The first cylinder 12 drives the first push rod 13 to displace, and then the sliding block 14 can be displaced, thereby driving the connecting shaft 15 to displace and slide inside the outer frame 1, so that one of the inclined scraping plates 8 can be displaced. At this time, the outer part of the transparent tape can be cleaned by the two inclined scraping plates 8. At the same time, with the help of the fixed shaft 9 and the pressing roller 10, the transparent tape can be flattened. At the same time, as the connecting shaft 15 displaces, the rotating plate 16 will rotate, and then the connecting rod 18 can be driven to slide inside the arc-shaped groove 20, so that the tensioning roller 19 can be displaced. At this time, the transparent tape can be tensioned by the tensioning roller 19. Subsequently, the transparent tape will pass over the tops of the two conduction rollers 4. At this time, the second cylinder 25 can be started, and the second cylinder 25 drives the second push rod 26 to displace, so as to adjust the height of the connecting plate 27 and the sealing roller 28. As the sealing roller 28 rises, the glue inside the fixed frame 24 will penetrate through the flow groove 29 to the outside of the brush 30, so that the transparent tape can be fully coated by the brush 30. Finally, the coated transparent tape will be wound by the winding roller 33.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
