The front sides of the unwinding roller 3 and the winding roller 4 are both provided with supporting mechanisms. A motor is installed on the rear side of the backboard 2, and the output shaft of the motor passes through the backboard 2 and is connected to the winding roller 4. The first electric slide rails 5 are symmetrically installed on the front and rear ends of the upper right part of the base 1. The two first electric slide rails 5 are slidably connected to the mounting seat 6, and the upper right side of the mounting seat 6 is evenly There are multiple mounting holes 61, which are adapted to the fixing bolts 71. A multiple positioning grooves 62 are provided on the upper part of the mounting seat 6, which correspond one-to-one to the mounting holes 61. The shape of the positioning grooves 62 is adapted to the upper part of the connecting frame 7. The connecting frame 7 is installed on the mounting seat 6 through the fixing bolts 71 and the mounting holes 61. The positioning grooves 62 are slidingly connected to the connecting frame 7. The cutting knife 72 is provided on the upper left side of the connecting frame 7, and the blade of the cutting knife 72 faces upward. The front side of the back plate 2 is provided with the clamping mechanism 8 and the tensioning mechanism 9. The clamping mechanism 8 is located above the winding roller 4, and the tensioning mechanism 9 is located between the unwinding roller 3 and the winding roller 4.

[0023] When in use, remove the support mechanisms on the front sides of the unwinding roller 3 and the winding roller 4 respectively, and put the double-sided film and the empty roll on the unwinding roller 3 and the winding roller 4 respectively, then reinstall the support mechanisms, and then the double-sided tape starts from the unwinding roller 3, passes through the lower side of the tensioning mechanism 9 and is connected to the empty roll of the winding roller 4, and then the first electric slide rail 5 drives the mounting seat 6 and the cutting knife 72 thereon to approach the winding roller 4, and the pressing mechanism 8 presses the double-sided tape on the empty roll, and the motor of the winding roller 4 starts to start the winding work. During work, the cutting knife 72 will cut the double-sided tape. After the winding work is completed, the pressing mechanism 8 is reset, and the first electric slide rail 5 drives the mounting seat 6 away from the winding roller 4. At this time, the wound double-sided tape can be removed. When double-sided tapes of different widths are required, the distance between the cutting knives 72 can be adjusted by installing the connecting frame 7 on the mounting holes 61 of different mounting seats 6.

[0024] like Figure 1 and Figure 4 As shown, the pressing mechanism 8 includes a fixed plate 81, a cylinder 82, a connecting plate 83, a telescopic rod 84, an elastic member 85 and a pressing roller 86.

As the winding operation progresses, the double-sided tape on the empty reel gradually increases and squeezes the pressure roller 86 to rise. The presence of the elastic member 85 and the telescopic rod 84 allows the pressure roller 86 to automatically adjust its height according to the change in the thickness of the double-sided tape layer, maintain a constant pressure, and avoid insufficient or excessive pressure due to the increase in the roll diameter.

When winding, the limit piece 11 and the fixed seat 10 play the role of supporting the unwinding roller 3 or the winding roller 4, and the fixed seat 10 ensures that the limit piece 11 will not rotate with the unwinding roller 3, the winding roller 4 and the connecting piece 12.

[0028] The lower side of the limiting member 11 contacts the base 1 , which can better support the unwinding roller 3 or the winding roller 4 .
