In the embodiment, the longitudinal sections of the first winding sleeve 44 and the second winding sleeve 43 are each an equilateral triangle, and of course in other embodiments, they can also be polygons other than an equilateral triangle, a quadrilateral or a pentagon, or can also be a circle. A side cavity for accommodating the second winding sleeve 43 is provided on the side surface of the first winding sleeve 44, a first convex part 441 which is centrally symmetrical and protrudes towards the center of the first winding sleeve 44 is provided on the inner wall of the side cavity in the circumferential direction, and the closed contour formed by the free ends of all the first convex parts 441 matches the outer contour of the second winding sleeve 43, so as to achieve the purpose of accommodating the second winding sleeve 43 in the side cavity. The winding core fixing assembly further includes an end sleeve 42 (as shown in Figure 3 In addition, the shaft hole 432 in the middle part of the second winding sleeve 43 is a hollow columnar structure with an inner diameter slightly larger than the outer diameter of the rotating shaft 41, so as to better axially fix and limit the winding sleeve.

[0023] The first winding sleeve 44 and the second winding sleeve 43 described above are respectively matched with winding cores of adhesive tape rolls with different inner diameters, so that the adhesive tape table can be matched with winding cores of different sizes. Specifically, the outer circumferential surface of the second winding sleeve 43 is provided with a second convex part 431 matched with the inner diameter of the winding core of an adhesive tape roll with a smaller inner diameter, which can achieve the purpose of combining the second winding sleeve 43 with the winding core of the smaller adhesive tape roll. The outer circumferential surface of the first winding sleeve 44 is also provided with a third convex part 442 having the same function as the second convex part 431, except that the third convex part 442 achieves the purpose of combining the first winding sleeve 44 with the winding core of an adhesive tape roll with a larger inner diameter. Of course, in other embodiments, there can be three or more winding sleeves, and the structural arrangement and matching relationship therebetween can be referred to the structural arrangement and matching relationship between the first winding sleeve and the second winding sleeve described above.

[0024] In addition, the outer circumferential surface of the rotating shaft 41 is also provided with a clamping groove 411 (as shown in Figure 3As shown in the figure, the end sleeve 42 is provided with a buckle that fits the clamping groove 411. The outer side of the end sleeve 42 is provided with four elastic pieces 421 that are centrally symmetrically arranged, and gaps are provided between adjacent elastic pieces. Thus, the elastic pieces can be retracted and released within a certain range, facilitating the installation and removal of the end sleeve 42 and the second through hole 34 on the horizontal support 31 of the adhesive tape platform.

[0025] In combination Figures 2-4 Further description is made to the adhesive tape platform in the embodiment. The adhesive tape platform in the embodiment comprises Figure 1 In addition to the roll core fixing assembly shown in the figure, the platform base 1 is also provided with a support. The support comprises a longitudinal support that extends upward and a horizontal support 31 for cutting the adhesive tape roll. The longitudinal support comprises a ring-shaped base 21 that is provided with opposite and parallel support arms 22 that extend upward, and the support arms 22 are provided with reinforcing ribs 24 and first through holes 23. The horizontal support 31 is provided with a second through hole 34 that is opposite to the first through hole 23. The end sleeve 42 of the roll core fixing assembly is connected with the adhesive tape platform through the first through hole 23 and the second through hole 34. The platform base is provided with a clamping ring 11 for clamping the ring-shaped base 21. The end of the horizontal support is also provided with a blade mounting platform 33 for fixing a blade 32.

[0026] A non-slip suction cup 52 is also provided at the bottom of the platform base 1, and the upper surface of the non-slip suction cup 52 is provided with an extension rod 53 that extends upward. The platform base 1 is provided with a fixing hole 12 through which the extension rod 53 passes and is positioned, and the end of the extension rod 53 is provided with a pin hole. The adhesive tape platform also comprises a pressing rod 5 for activating and releasing the non-slip suction cup 52, and the pressing rod 5 is connected with the extension rod 53 through a pin 51 and the pin hole.

[0027] When installing the adhesive tape 100, select the roll sleeve that fits the roll core. Taking the first roll sleeve 44 as an example, the second roll sleeve 43 is accommodated in the side cavity of the first roll sleeve 44, and the two end sleeves 42 are respectively sleeved into the coaxially arranged first through hole 23 and second through hole 34. Then, the assembled adhesive tape, first roll sleeve 44, and second roll sleeve 43 embedded in the first roll sleeve 44 are placed between the two end sleeves 42, and finally the shaft 41 passes through the shaft hole 432 in the first through hole 23 and the second through hole 34. When the adhesive tape platform needs to be fixed on the desktop, the non-slip suction cup 52 is emptied by operating the pressing rod 5, so that the platform base 1 is fixed on the workbench. The non-slip suction cup 52 can be released by reversing the operation of the pressing rod 5. If the second roll sleeve 43 is fitted, only the first roll sleeve 44 needs to be removed, and the second roll sleeve 43 can be used alone. The assembly process is as above and will not be repeated here.

[0028] The roll core fixing assembly and the adhesive tape station containing the same in the embodiment can make the adhesive tape station used for adhesive tape rolls of various specifications through the nested multiple roll sleeves, further expand the applicable range, and the nested structure facilitates the roll sleeve storage and flexible selection.
