Description

Technical Field

[0001] This utility model relates to the technical field of adhesive strip production equipment, and in particular to an adhesive strip application device. Background Technology

[0002] Rubber strips are widely used in car doors, windows, bodies, seats, sunroofs, engine compartments, and trunks, playing important roles in waterproofing, sealing, sound insulation, dustproofing, antifreeze, shock absorption, heat preservation, and energy saving. However, due to the special nature of the rubber material itself, the adhesive application stability of rubber strips is poor when applying adhesive to the surface, and the tape is prone to falling off later. Therefore, it is necessary to apply adhesive to the surface of the rubber strip before applying the tape to improve the stability of the tape adhering to the strip. Thus, a rubber strip application device is needed. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an adhesive strip applicator to solve the problem of applying adhesive to adhesive strips in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0005] An adhesive strip application device, comprising:

[0006] An oven assembly, wherein an adhesive applicator is provided at the input end of the oven assembly to pre-apply adhesive to the adhesive strip, and an adhesive applicator is provided at the output end of the oven assembly to apply adhesive to the surface of the adhesive strip after it has been coated.

[0007] The adhesive applicator includes an adhesive applicator frame, on which an adhesive applicator tray and a paper receiving tray are provided. An adhesive tape tensioning wheel is provided between the adhesive applicator tray and the paper receiving tray. An adhesive tape spreading roller is provided at the bottom of the adhesive applicator frame. The adhesive tape spreading roller can move up and down in the vertical direction. An adhesive tape guide wheel is provided between the adhesive tape spreading roller and the paper receiving tray.

[0008] To achieve the above technical solution, glue is pre-applied to the adhesive strip by the glue applicator, so that an adhesive layer exists on the surface of the adhesive strip to facilitate the subsequent adhesion of tape to the adhesive strip. In order to improve the drying speed of the glue on the surface of the adhesive strip after glue application, the adhesive strip is first dried by the drying oven assembly, and then the tape application assembly performs the tape application process. By setting a tape tensioning wheel between the glue tray and the paper receiving tray, the tension of the tape can be adjusted to match the tape conveying speed. The tape laying roller can move up and down in the vertical direction. When tape needs to be applied to the adhesive strip, the tape guide wheel guides the tape to the tape application working surface, and then the tape laying roller moves downward to press the tape onto the adhesive strip. As the adhesive strip moves, the tape laying roller rotates, thereby smoothly pressing the tape onto the surface of the glued adhesive strip.

[0009] In one embodiment of the present invention, a lifting drive is provided between the root of the tape laying roller and the adhesive applicator. The tape laying roller is located at the movable end of the lifting drive, and the lifting drive drives the tape laying roller to move up and down to press the tape onto the adhesive strip.

[0010] To achieve the above technical solution, a lifting drive component is set up to drive the tape spreading roller to move up and down. When tape needs to be applied, the lifting drive component drives the tape spreading roller to move downward, pressing the tape firmly onto the surface of the adhesive strip. When tape is not needed, the lifting drive component drives the tape spreading roller to move upward, away from the tape application surface, providing space for the conveying of the adhesive strip.

[0011] In one embodiment of the present invention, a tape tensioning plate is further provided between the upper glue tray and the paper receiving tray. The tape tensioning plate is slidably connected to the adhesive applicator in the vertical direction. A set of tape tensioning wheels is provided on the tape tensioning plate. After the tape on the upper glue tray passes through the tape tensioning wheels on the tape tensioning plate, it wraps around to the paper receiving tray.

[0012] To achieve the above technical solution, a tape tensioning plate is slidably connected to the tape application frame in the vertical direction, and a set of tape tensioning wheels is set on the tape tensioning plate, which can adjust the tension of the tape during the feeding process, thereby improving the conveying stability of the tape and better matching the conveying speed of the tape strip, so as to achieve more stable tape application on the surface of the tape strip.

[0013] In one embodiment of the present invention, the glue application assembly includes a glue application frame, a glue strip slide is provided in the glue application frame, a glue strip guide wheel is provided in the glue strip slide, and a glue application head is provided on the glue application frame near the oven assembly.

[0014] To achieve the above technical solution, a guide wheel for the rubber strip is installed inside the rubber strip slide, which ensures the stability of the rubber strip conveying and, in conjunction with the coating head, achieves a stable coating effect on the surface of the rubber strip.

[0015] In one embodiment of the present invention, an upper glue head frame is provided between the glue applicator and the glue applicator frame, the glue applicator frame is located at the front end of the glue head frame, and the glue applicator can move up and down on the glue head frame.

[0016] To achieve the above technical solution, by setting up a glue applicator frame, and allowing the glue applicator head to move up and down on the glue applicator frame, it is possible to facilitate the glue application process on the surface of the glue strip. Depending on the type of glue strip, the height of the glue applicator head can be adjusted to ensure that the glue strip surface can be coated more evenly.

[0017] In one embodiment of the present invention, two sets of fixed glue rollers are provided on the side of the glue strip slide near the oven assembly, and the shaft boxes of the two sets of fixed glue rollers are arranged in the vertical direction.

[0018] To achieve the above technical solution, by arranging two sets of fixed glue roller shaft boxes in the vertical direction, the position of the glue strip in the horizontal direction can be adjusted, thereby improving the stability of glue strip conveying and making the glue coating on the surface of the glue strip more uniform.

[0019] In one embodiment of the present invention, the oven assembly includes an oven rack and a glue strip oven, wherein the glue inlet of the glue strip oven and the glue outlet of the glue coating assembly are at the same horizontal height.

[0020] To achieve the above technical solution, the glue inlet of the glue drying oven and the glue outlet of the glue coating component are at the same horizontal height, which can improve the conveying stability of the glued glue strip and make the glue on the surface of the glue strip more uniform.

[0021] As described above, the adhesive strip applicator of this utility model has the following beneficial effects: Adhesive is pre-applied to the adhesive strip by the adhesive applicator, thus creating an adhesive layer on the surface of the adhesive strip to facilitate subsequent tape application. To improve the drying speed of the adhesive on the adhesive strip surface after application, an oven assembly is used to dry the adhesive strip before the applicator performs the tape application. A tape tensioning wheel is installed between the glue tray and the paper receiving tray to adjust the tape tension to match the adhesive strip conveying speed. The tape spreading roller can move vertically up and down. When tape needs to be applied to the adhesive strip, the tape guide wheel guides the tape to the applicator surface, and the tape spreading roller moves downwards to press the tape firmly onto the adhesive strip. As the adhesive strip moves, the tape spreading roller rotates, thus smoothly pressing the tape onto the surface of the adhesive strip after application. Attached Figure Description

[0029] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please see Figures 1 to 5 This utility model provides an adhesive strip applicator, including an input end of an oven assembly with an adhesive applicator for pre-applying adhesive to the adhesive strip, and an output end of the oven assembly with an adhesive applicator for applying adhesive to the surface of the applied adhesive strip. The adhesive applicator includes an applicator frame 1, an adhesive applicator tray 2 and a paper receiving tray 3, a tape tensioning wheel 4 between the adhesive applicator tray 2 and the paper receiving tray 3, a tape spreading roller 5 at the bottom of the applicator frame 1, the tape spreading roller 5 being vertically movable, and a tape guide wheel 6 between the tape spreading roller 5 and the paper receiving tray 3.

[0031] Adhesive is pre-applied to the adhesive strip by the gluing assembly, so that an adhesive layer exists on the surface of the adhesive strip to facilitate the subsequent adhesion of tape to the adhesive strip. In order to improve the drying speed of the adhesive on the surface of the adhesive strip after gluing, the adhesive strip is first dried by the drying oven assembly, and then the tape application assembly is used for tape application. By setting the tape tensioning wheel 4 between the glue tray 2 and the paper receiving tray 3, the tension of the tape can be adjusted to match the tape conveying speed. The tape laying roller 5 can move up and down in the vertical direction. When tape needs to be applied to the adhesive strip, the tape guide wheel 6 guides the tape to the tape application working surface, and then the tape laying roller 5 moves downward to press the tape onto the adhesive strip. As the adhesive strip moves, the tape laying roller 5 rotates, thereby pressing the tape smoothly onto the surface of the adhesive strip after gluing.

[0032] A lifting drive 7 is provided between the root of the tape spreading roller 5 and the adhesive application frame 1. The tape spreading roller 5 is located at the movable end of the lifting drive 7. The lifting drive 7 drives the tape spreading roller 5 to move up and down to press the tape onto the adhesive strip. By setting the lifting drive 7 to drive the tape spreading roller 5 to move up and down, when tape needs to be applied, the lifting drive 7 drives the tape spreading roller 5 to move downward to press the tape tightly onto the surface of the adhesive strip. When tape does not need to be applied, the lifting drive 7 drives the tape spreading roller 5 to move upward, away from the adhesive application working surface, providing space for the conveying of the adhesive strip.

[0033] A tape tensioning plate 8 is also provided between the upper glue tray 2 and the paper receiving tray 3. The tape tensioning plate 8 is slidably connected to the adhesive applicator 1 in the vertical direction. A set of tape tensioning rollers 4 are provided on the tape tensioning plate 8. After the tape on the upper glue tray 2 passes through the tape tensioning rollers 4 on the tape tensioning plate 8, it winds around to the paper receiving tray 3 and is slidably connected to the adhesive applicator 1 in the vertical direction by the tape tensioning plate 8. The tape tensioning plate 8 is provided with a set of tape tensioning rollers 4, which can adjust the tension of the tape during the feeding process, thereby improving the conveying stability of the tape and better matching the conveying speed of the adhesive strip, so as to achieve more stable adhesive application on the surface of the adhesive strip.

[0034] The glue coating assembly includes a glue coating frame 9, a glue strip slide 10 is provided inside the glue coating frame 9, a glue strip guide wheel 11 is provided inside the glue strip slide 10, and a glue coating head 12 is provided on the glue coating frame 9 near the oven assembly. By providing the glue strip guide wheel 11 inside the glue strip slide 10, the stability of glue strip conveying can be ensured, so as to cooperate with the glue coating head 12 to achieve a stable glue coating effect on the surface of the glue strip.

[0035] A glue applicator 13 is provided between the glue applicator 12 and the glue applicator frame 9. The glue applicator frame 9 is located at the front end of the glue applicator frame, and the glue applicator 12 can move up and down on the glue applicator frame. By providing the glue applicator frame 13 and allowing the glue applicator 12 to move up and down on the glue applicator frame, it is convenient to apply glue to the surface of the glue strip. Depending on the type of glue strip, the height of the glue applicator 12 can be adjusted so that the glue strip surface can be coated more evenly.

[0036] Two sets of fixed glue rollers 14 are provided on the side of the rubber strip slide 10 near the oven assembly. The shaft boxes of the two sets of fixed glue rollers 14 are arranged in the vertical direction. By arranging the shaft boxes of the two sets of fixed glue rollers 14 in the vertical direction, the position of the rubber strip in the horizontal direction can be adjusted, thereby improving the stability of the rubber strip conveying and making the glue coating on the surface of the rubber strip more uniform.

[0037] The oven assembly includes an oven rack 15 and a rubber strip oven 16. The glue inlet of the rubber strip oven 16 is at the same level as the glue outlet of the coating assembly. Placing the glue inlet of the rubber strip oven 16 at the same level as the glue outlet of the coating assembly can improve the conveying stability of the coated rubber strip and make the glue on the surface of the rubber strip more uniform.

[0038] This invention uses a gluing assembly to pre-apply glue to the adhesive strip, creating an adhesive layer on the strip's surface to facilitate subsequent tape application. To improve the drying speed of the glue on the coated strip, an oven assembly is used to dry the strip before applying the tape. A tape tensioning wheel is installed between the glue tray and the paper receiving tray to adjust the tape tension to match the strip's conveying speed. The tape spreading roller can move vertically up and down. When tape needs to be applied, the tape guide wheel guides the tape to the application surface, and the tape spreading roller moves downward to press the tape onto the strip. As the strip moves, the tape spreading roller rotates, ensuring the tape is smoothly pressed onto the coated strip surface.
