referring to fig. 1 and 4, the two ends of the double-threaded rod 431 are respectively threadedly assembled with a first connecting block 4311, the sliding rod 432 is vertically slidably sleeved with a second connecting block 4321, one end of the upper laminating roller 41 is rotatably connected with the first connecting block 4311 located above, the other end of the upper laminating roller is rotatably connected with the second connecting block 4321 located above, one end of the lower laminating roller 42 is rotatably connected with the first connecting block 4311 located below, and the other end of the lower laminating roller is rotatably connected with the second connecting block 4321 located below.

When the gap between the upper attaching roller 41 and the lower attaching roller 42 needs to be adjusted, the driving motor 433 is started, the driving motor 433 drives the double-headed threaded rod 431 to rotate, so that the two first connecting blocks 4311 are driven to rotate, and due to the sliding assembly of the sliding rod 432 and the second connecting block 4321, the upper attaching roller 41 and the lower attaching roller 42 are close to or far away from each other, so that the adjustment of the gap between the upper attaching roller 41 and the lower attaching roller 42 is realized, the automation of the adjustment of the upper attaching roller 41 and the lower attaching roller 42 is realized, and the gap between the upper attaching roller 41 and the lower attaching roller 42 is convenient to adapt to glue and an original film 13 with different thicknesses.

The implementation principle of the production line of the high-temperature-resistant transparent adhesive tape in the embodiment of the application is as follows: when the device works, a worker drives the adjusting plate 82 to lift up and down from one side far away from the coating wheel 31 according to the thickness of the needed glue on the original film 13 to realize the lifting of the scraping plate 7, so that the distance between the bottom of the scraping plate 7 and the upper surface of the original film 13 is adjusted to be matched with the thickness of the needed glue; the original film 13 is led out by the traction mechanism 2 and conveyed to the coating mechanism 3, the coating wheel 31 sprays glue on the upper surface of the original film 13 and then conveys the glue to the scraper 7, the scraper 7 evenly scrapes the glue on the surface of the original film 13 to the required glue thickness, the glue is conveyed to the laminating mechanism 4 to be laminated between the glue and the original film 13, the original film 13 coated with the glue is rolled by the rolling mechanism 5 to form a long roll of adhesive tape, and finally the cutting mechanism 6 cuts the long roll of adhesive tape to obtain a small roll of adhesive tape.

The embodiment of the application also discloses a production process of the high-temperature-resistant transparent adhesive tape.

The production process of the high-temperature-resistant transparent adhesive tape comprises the following steps:

s1, sizing: leading out the original film 13 from the original film 13 roll through the traction mechanism 2, conveying the led-out original film 13 to the lower part of a coating wheel 31 of the coating mechanism 3, pumping glue in a glue storage tank 32 into the coating wheel 31 through a glue guide pipe 33 by a glue pump 34, and then dripping the glue on the surface of the original film 13 through a plurality of glue flowing holes 311 at the bottom of the coating wheel 31;

s2, homogenizing: conveying the original film 13 output by the coating wheel 31 to a scraper 7, uniformly scraping the glue sprayed on the surface of the original film 13 by the scraper 7, simultaneously driving one side of an adjusting plate 82 far away from the coating wheel 31 to lift through a driving part 81 according to the thickness of the glue of the adhesive tape by a worker, further changing the height of the scraper 7, and adjusting the distance between the bottom of the scraper 7 and the upper surface of the original film 13 to obtain the adhesive tape with glue of different thicknesses;

s3, glue fixation: the original film 13 output by the scraper 7 is conveyed to the laminating mechanism 4, and the original film 13 passes through a gap between the upper laminating roller 41 and the lower laminating roller 42 so as to firmly laminate the glue adhered to the surface of the original film 13;

s4, rolling: conveying the original film 13 output by the laminating mechanism 4 to the winding mechanism 5, and winding the original film 13 coated with glue to form a long roll of adhesive tape;

s5, slitting: and the slitting mechanism 6 divides the rolled long-roll adhesive tape into strips and strips, and cuts the strips into small-roll adhesive tapes.

The implementation principle of the production process of the high-temperature-resistant transparent adhesive tape in the embodiment of the application is as follows: the original film 13 roll is output to the lower part of the coating wheel 31 at the coating mechanism 3 through the traction mechanism 2 to be sprayed with glue, along with the continuous transmission of the original film 13, the glue on the surface of the original film 13 is uniformly scraped to the required glue thickness by the scraper 7, the glue is more firmly attached to the original film 13 through the attaching mechanism 4, finally, the glue is wound by the winding mechanism 5, and then, the glue is cut by the cutting mechanism 6 to form a finished adhesive tape, so that the automation of adhesive tape production is realized.
