To facilitate adjustment of the degree of tension; as shown in fig. 2, be provided with tensioning adjustment mechanism between backing roll 14 and the take-up cylinder 13, tensioning adjustment mechanism includes lifting roller 12 and two cranes 10, and two crane 10 inner walls sliding connection have two lifting slide 9 respectively, and lifting roller 12 both ends are rotated respectively and are connected in two lifting slide 9 inner walls, and a lifting slide 9 top inner wall is rotated and is connected with lift knob 11, and lift knob 11 passes through threaded connection in a crane 10 top inner wall, and another lifting slide 9 top inner wall has the tensioning guide arm through the screw fixation, and tensioning guide arm sliding connection is in another crane 10 top inner wall.

Example 2:

a method for preparing an ultrathin adhesive tape, as shown in fig. 1-7, comprising the following steps:

s1: one end of the adhesive tape base film 5 is drawn to a winding roller 13 to be fixed;

s2: the servo adjusting motor 21 controls the adjusting stud 18 to rotate by adjusting parameters of the control screen 2, so as to adjust the distance between the rubber scraping roller 26 and the adhesive tape base film 5;

s3: the height of the lifting roller 12 is adjusted through the lifting knob 11, and the tensioning degree of the adhesive tape base film 5 is controlled;

s4: controlling the feeding of the adhesive tape base film 5, spraying an adhesive on the top surface of the adhesive tape base film 5 by using an adhesive spraying mechanism, and synchronously winding by using a winding roller 13;

s5: controlling the scraping roller 26 to rotate to scrape off the redundant adhesive;

s6: and periodically controlling the scraper motor 16 to work, and cleaning the top surface of the frictioning baffle 25 by using the translation scraper 32 until the glue spraying and rolling work is finished.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
