Description

Technical Field

[0001] This utility model relates to the technical field of aluminum foil tape production equipment, specifically to an aluminum foil tape coating machine. Background Technology

[0002] Foil tape is a functional tape made by coating aluminum foil with pressure-sensitive adhesive, hot melt adhesive and other adhesives evenly on the surface of aluminum foil using a coating machine, followed by curing, slitting and other processes. In the production process of aluminum foil tape, the coating machine is the core equipment to achieve uniform adhesion of adhesive to the surface of aluminum foil.

[0003] Existing aluminum foil tape coating machines have the following shortcomings: the pressure between the coating roller and the aluminum foil tape is fixed, making it impossible to adjust the pressure according to the tape thickness and adhesive viscosity, which easily leads to excessive adhesive coating on thin tapes and insufficient adhesive coating on thick tapes, resulting in uneven coating; low accuracy in adhesive thickness control: most equipment only controls the adhesive thickness of the coating roller through a single scraper, without secondary correction of the adhesive on the tape surface, and the scraper position adjustment structure is unstable, easily causing deviations in adhesive layer thickness; to address the above problems, this utility model proposes an aluminum foil tape coating machine with adjustable coating pressure, dual thickness control, and auxiliary curing function.

[0016] Please see Figure 1-5 This utility model provides a technical solution: an aluminum foil tape coating machine, including a processing plate 1 and tape 33. Side plates 2 are bolted to the front and rear sides of the upper part of the processing plate 1, forming the main support frame of the equipment. A storage box 3 is welded to the middle of the upper side of the processing plate 1 for storing adhesive liquid. A first connecting frame 11 is bolted to the front and rear of one side of the upper part of the storage box 3. A lifting rod 13 is bolted to the upper part of the storage box 3 on the rear side. A rear movable block 4 is slidably installed on the outer side of the lifting rod 13. A third threaded rod 12 is rotatably connected to the upper part of the storage box 3 on the front side of the first connecting frame 11 via a bearing. The movable blocks 4 on both sides are rotatably connected via bearings. A glue-applying roller 5 is movably connected, and the lower part of the glue-applying roller 5 can extend into the glue storage box 3 to pick up glue liquid. By rotating the third threaded rod 12, the front movable block 4 can be driven to move axially. In conjunction with the rear movable block 4 sliding along the lifting rod 13, the glue-applying roller 5 is raised and lowered as a whole, changing its contact pressure with the tape 33. A moving groove 6 is opened on one side of the movable block 4. A first connecting plate 7 is slidably connected inside the moving groove 6. A first scraper 10 is fixedly connected to the side of the first connecting plate 7 facing the glue-applying roller 5 by bolts.

The first sliding rod 9 slides through the sliding hole and is mounted on the rear side of the first connecting plate 7. The front moving groove 6 is rotatably connected to the first threaded rod 8 by bearing. The first threaded rod 8 is screwed to the front side of the first connecting plate 7 through the threaded hole. Rotating the first threaded rod 8 can drive the first connecting plate 7 to slide along the guide of the first sliding rod 9, and adjust the distance between the first scraper 10 and the outer circumference of the coating roller 5 to achieve the smoothing and thickness control of the adhesive on the surface of the coating roller 5. A second sliding rod 18 is fixedly connected to the upper part of the glue storage box 3 by welding inside the rear second connecting frame 14. The second sliding rod 18 slides through the sliding hole and is mounted on the rear side of the second connecting plate 15. A second threaded rod 17 is rotatably connected to the upper part of the glue storage box 3 by bearing inside the front second connecting frame 14. The second threaded rod 17 is screwed onto the front side of the second connecting plate 15 through the threaded hole. Rotating the second threaded rod 17 can drive the second connecting plate 15 to slide along the guide of the second sliding rod 18, adjust the distance between the second scraper 16 and the surface of the tape 33, and perform secondary thickness control on the glued tape 33. The lower part between the side plates 2 is rotatably connected from left to right by bearings to a lower positioning roller 28, an upper positioning roller 29, and a parallel roller 30. The upper part of the lower positioning roller 28 is flush with the lower part of the upper positioning roller 29 and lower than the upper part of the coating roller 5, ensuring that the tape 33 can contact the coating roller 5. The lower part of the upper positioning roller 29 is flush with the lower part of the parallel roller 30. The second scraper 16 is set between the upper positioning roller 29 and the parallel roller 30, corresponding to the path of the tape 33 after coating. The upper part between the side plates 2 is rotatably connected from left to right by bearings to two sets of fixed rollers 32 and a steering roller 31. The steering roller 31 is flush with one side of the parallel roller 30 and the upper side of the lower fixed roller 32, so as to realize the stable conveying and steering of the tape 33. The middle part between the side plates 2 is fixedly connected by bolts to a partition plate 19, which is used to separate the upper and lower functional areas of the equipment and prevent the glue from contaminating other parts. A heating box 20 is fixedly connected to the upper middle part of the side plate 2 by bolts. Several sets of heating plates 23 are fixedly connected to the inner side wall of the heating box 20 by bolts. Several sets of vent holes 22 are opened at the lower part of the heating box 20. An air inlet pipe 21 is fixedly connected to the upper middle part of the heating box 20 by welding. Inside the air intake pipe 21, a mounting bracket 24 is fixedly connected by welding.

An isolation mesh 34 is fixedly connected to the upper and lower ends of the air intake pipe 21 by bolts to prevent impurities from entering the heating box 20. The side plate 2 has a connecting hole 27 in the middle, which is directly opposite the first connecting frame 11 and the second connecting frame 14, so as to facilitate the control of the internal structure from the outside.

[0017] Working principle: When using this utility model, rotating the third threaded rod 12 drives the front movable block 4 to move axially along the third threaded rod 12, and the rear movable block 4 slides synchronously along the lifting rod 13, adjusting the glue-applying roller 5 to a height suitable for the tape 33 to be processed, controlling the contact pressure between the glue-applying roller 5 and the tape 33, adjusting the first scraper 10: according to the required glue layer thickness, rotating the first threaded rod 8 causes the first connecting plate 7 to slide along the first sliding rod 9, adjusting the distance between the first scraper 10 and the glue-applying roller 5; adjusting the second scraper 16: rotating the second threaded rod 17 causes the second connecting plate 15 to slide along the second sliding rod 18, adjusting the distance between the second scraper 16 and the tape 33 to match the thickness control parameters of the first scraper 10; starting the heating box 20: the heating plate 23 is powered on for preheating, and at the same time the motor 25 is started to drive the fan 26 to form hot air, which is blown from the vent 22 towards the tape path; Conveying tape 33: The aluminum foil tape 33 is sequentially passed around the lower positioning roller 28, the upper positioning roller 29, and at this time, the tape 33 contacts the coating roller 5, picks up the adhesive, and passes through the parallel roller 30, the turning roller 31, and the fixed roller 32 to form a stable conveying path; Coating and thickness control: After the coating roller 5 picks up the adhesive from the adhesive storage box 3, the first scraper 10 scrapes the adhesive on its surface and controls the thickness. When the coated tape 33 is conveyed to the parallel roller 30 via the upper positioning roller 29, the second scraper 16 scrapes the adhesive on the surface of the tape 33 a second time to ensure uniform thickness; Adhesive curing: When the coated tape passes under the heating box 20, hot air is blown from the vent 22 onto the surface of the tape 33 to accelerate the curing of the adhesive.
