Description

Technical Field

[0001] This utility model relates to the field of tape processing technology, and in particular to a novel adjustable tape coating equipment. Background Technology

[0002] Adhesive tape comes in rolls, with its adhesive side used for bonding items such as repairing books, pasting paper, and securing packaging. This type of tape typically uses a plastic film as the base material, with an adhesive coated on one side. Tape coating equipment, also known as a tape coating machine, is a specialized machine used to produce tape (especially BOPP sealing tape). Its main function is to apply a quantitative layer of adhesive or coating to a base material (such as plastic film or paper), followed by drying and rewinding processes to produce the tape.

[0003] The prior art patent number CN219647990U discloses an environmentally friendly coating machine for tape production, which solves the problems that the screen on the coating machine is covered by dust in the factory when the coating machine is in the factory for a long time, making it impossible for people to observe the correct data accurately. In addition, people need to use a blade to cut multiple tapes one by one, which may cause people to not be able to find the location of the blade and leave it somewhere, which may pose a safety hazard. In existing technologies, when applying adhesive to one side of a tape, the coating roller is usually rotated for application. In these technologies, the position of the coating roller inside the coating equipment is usually fixed, making it inconvenient to adjust its position. The gap between the coating roller and the tape directly affects the coating quality and uniformity. If the gap is too large, it may lead to uneven coating, missing areas, or insufficient coating. If the gap is too small, it may result in excessive coating on the tape surface, causing waste and even affecting the tape's performance and usability. Furthermore, some tapes require a thicker coating layer to increase their tackiness, while others may require a thinner coating layer to maintain their transparency and flexibility, thus failing to meet different coating requirements.

[0032] Working principle: When applying adhesive to the tape strip, one end of the tape strip on the outer unwinding roller is first pulled out, passes over the first auxiliary roller 6 on one side inside the mounting frame 1, then winds around to the underside of the second auxiliary roller 7, then winds around to the top of the connecting roller 8, passes through to the underside of the second auxiliary roller 7 and the topside of the first auxiliary roller 6 on the other side inside the mounting frame 1, and then winds onto the take-up roller. When adjusting the position of the adhesive application roller 9, the first stepper motor 19 is turned on. Under the action of its internal gearbox, the output end drives the bidirectional stud 18 to rotate. Then, under the action of the thread, it drives the two connecting blocks 16 to move in opposite directions, causing the rotation... The rod 15 rotates, which in turn causes the adjusting block 14 to slide inside the connecting groove 13. Under the connection of the rotating shaft 10, the position of the coating roller 9 is moved, thereby adjusting the closeness to the tape surface according to the usage requirements. Then, the delivery pump 4 is turned on, and under the action of the lower glue tube 3, the glue inside the glue tank 2 is delivered to the inside of the glue spraying tube 5 and sprayed downwards. When it is sprayed onto the coating roller 9, the drive motor 22 is turned on, and the output end of its internal gearbox drives the gear 23 to rotate. When it meshes with the outer gear ring 20, it drives the outer gear ring 20 to rotate, thereby driving the coating roller 9 to rotate and perform the glue application operation on the tape strip.

[0033] When glue drips from the bottom of the mounting frame 1, the second stepper motor 27 is turned on. Under the influence of the gearbox, its output drives the second bevel gear 28 to rotate. When it meshes with the first bevel gear 26, it drives the first bevel gear 26 to rotate, thereby driving the bidirectional lead screw 25 to rotate. With the sliding block 29 inside the mounting groove 24, the bidirectional lead screw 25 drives the two moving blocks 29 to move away from each other, thereby driving the support rod 30 to be lifted and pushed to the scraper 31 to scrape at the bottom of the mounting frame 1, pushing the glue to one side of the bottom of the mounting frame 1. Then, the stepper motor 33 is turned on. Under the influence of the gearbox, its output drives the screw 34 to rotate. Under the action of the thread, the mounting block 35 slides inside the groove 32, causing the scraper 36 to push the scraped glue outside the scraper 31 and the inclined rod 37, pushing the glue into the glue collection box 38 for collection.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
