[0027] Furthermore, firstly, glue is added to the inside of the glue tank 1 until the amount of glue reaches the middle position of the lower coating roller 403. The adhesive tape to be coated passes through the guide wheel 3 and passes between the two coating rollers 403. The first motor 404 and the suction pump 414 are started. The first motor 404 drives the large gear 405 to drive the two small gears 406 to rotate, and the two coating rollers 403 rotate. When the lower coating roller 403 rotates, it contacts the glue inside the glue tank 1, and then the adhesive tape is coated. At the same time, the suction pump 414 is operated.

The tape cotton to be coated passes through the guide wheel 3 to pass between the two coating rollers 403. Then, the three groups of heating rods 503 are heated. The second motor 504 is started to drive the worm 505 to drive a group of worm gears 502 to rotate, thereby causing a group of stirring columns 501 to rotate, which can cause the three groups of heating rods 503 to rotate, making it easier to heat the glue inside the glue tank 1 so that the glue has better fluidity when coating. The first motor 404 and the suction pump 414 are started. The first motor 404 drives the large gear 405 to drive the two small gears 406 to rotate, and the two coating rollers 4 03 generates rotation, and when the coating roller 403 below rotates, it contacts the glue inside the glue box 1, and then coats the bottom of the tape cotton with glue.
