[0031] A frame having two relatively arranged mounting brackets 10;

[0032] A pay-off roll 20, the two ends of which are respectively rotatably installed on the two mounting brackets 10, and the pay-off roll 20 winds a strip-shaped article;

[0033] A material rack 100 is arranged on the front side of the pay-off roll 20;

[0034] Two first clamps 30 are respectively installed on the two mounting brackets 10 through a vertical driving mechanism 40 and are respectively located above the two ends of the pay-off roll 20;

[0035] The cutter assembly 50 is mounted on the frame via a rotary drive mechanism, and the rotary drive mechanism is used to drive the cutter assembly 50 to rotate around the unwinding roller 20;

[0036] Two second clamps 60, mounted on the cutter assembly 50 and located at both ends of the unwinding roller 20;

[0037] The two receiving platforms 70 are respectively mounted on the two mounting frames 10 and the two receiving platforms 70 are respectively located at the front sides of the two ends of the unwinding roller 20 .

[0038] See attached Figure 1 As shown, the first tape roll 1a is placed at the rear end of the two receiving platforms 70 for winding, and at this time, the two ends of the second tape roll 2a are clamped by the two first clamps 30 respectively;

[0039] See attached Figure 2 As shown, after the first tape roll 1a is wound up, the cutter assembly 50 is driven by the rotary drive mechanism to rotate to the top of the unwinding roll 20 with the unwinding roll 20 as the axis, and then the two vertical drive mechanisms 40 drive the two first clamps 30 to descend until the two first clamps 30 and the two second clamps 60 are distributed at the same height, so that the second tape roll 2a is placed on the second clamps 60;

[0040] The cutter assembly 50 cuts the film, and the film is rewound on the second belt roll 2a, and the first belt roll 1a that has been wound is moved out from the receiving platform 70, and the cutter assembly 50 continues to rotate forward, and the second clamp 60 drives the two ends of the second belt roll 2a to rotate forward and pass one side of the receiving platform 70, and the second belt roll 2a on the second clamp 60 is placed on the receiving platform 70, as shown in the attached figure. Figure 4 The cutter assembly 50 continues to rotate downward and waits for the second belt winding roller 2a to complete winding.

[0041] In order to allow the tape roll to be stably wound on the receiving platform 70, a groove is further provided on the receiving platform 70, and the tape roll is placed in the groove for winding.

[0042] In this embodiment, the cutter assembly 50 is distributed between the two receiving platforms 70 so that the cutter assembly 50 can rotate between the two receiving platforms 70 with the unwinding roller 20 as the axis, and can place both ends of the second belt winding roller 2a on the receiving platform 70.

[0043] In order to ensure smooth transfer of the second belt roll 2a among the first clamp 30, the second clamp 60 and the fourth clamp 90, the two first clamps 30 are distributed on both sides of the two fourth clamps 90 close to each other, and the two second clamps 60 are distributed on both sides of the two receiving tables 70 away from each other.

[0044] Preferably, in order to facilitate the loading of the second belt roll 2a, the method further comprises:

[0045] The two fourth clamps 90 are rotatably mounted on the two mounting frames 10 through the roller drive mechanism. Under the action of the roller drive mechanism, the two fourth clamps 90 can be swung on the mounting frames 10 on the same side to the front end of the material receiving platform 70 on the same side or the left and right sides of the material rack 100.

[0046] Two fifth clamps 110, the two fifth clamps 110 are respectively mounted on the two mounting frames 10 through a swing driving mechanism, and the two fifth clamps 110 are respectively located on the sides of the two fourth clamps 90 that are away from each other;

[0047] The two vertical drive mechanisms 40 are respectively installed on the mounting frame 10 through horizontal moving mechanisms, and the horizontal moving mechanisms are used to drive the vertical drive mechanisms 40 to drive the first clamp 30 to move back and forth between the front side of the receiving platform 70 and the top of the unwinding roller 20.

[0048] The second belt roll 2a is placed on the material rack 100 to wait for replacement, and both ends of the second belt roll 2a extend out of the material rack;

[0049] like Figure 3 As shown, the fourth clamps 90 are respectively swung to one side of the material rack 100 on the mounting frame 10 on the same side under the action of the shift roller driving mechanism, and the shift roller driving mechanism drives the fourth clamps 90 to swing upward, so that the two fourth clamps 90 clamp the two ends of the second belt roll 2a on the material rack 100 and continue to swing upward to the front side of the receiving platform 70, as shown in FIG. Figure 4 As shown;

[0050] Reference Figure 5 As shown, the swing drive mechanism drives the two fifth clamps 110 to swing upward from bottom to top, until the fifth clamps 110 swing to the front side of the receiving platform 70, the vertical drive mechanism 40 drives the two first clamps 30 to descend, the fifth clamps 110 continues to swing upward and drives the second belt roll 2a to continue to move upward until it is flush with the height of the two first clamps 30;

[0051] like Figure 6 As shown, the horizontal moving mechanism drives the first clamp 30 to move forward so that the first clamp 30 clamps the second belt winding roller 2a, the vertical driving mechanism 40 drives the second belt winding roller 2a upward away from the fifth clamp 110, and the horizontal moving mechanism then drives the two first clamps 30 to move above the unwinding roller 20.

[0052] In this embodiment, the fifth fixture 110 is provided with a clamping groove. When the fifth fixture 110 swings to the front side of the receiving table 70 and is at the same height as the first fixture 30, the clamping grooves on the fifth fixture 110 face upward, so that when the fifth fixture 110 swings to the front side of the receiving table 70, it can directly drive the second tape roller 2a to swing upward; and when the fifth fixture 110 swings to the same height as the first fixture 30, the clamping groove of the fifth fixture 110 faces upward, and the vertical driving mechanism 40 drives the two first fixtures 30 to move upward away from the two fifth fixtures 110.

[0053] In this embodiment, the first fixture 30 and the second fixture 60 are provided with clamping openings. The clamping opening of the first fixture 30 faces forward. When the cutter assembly 50 rotates above the unwinding roller 20, the clamping openings of the two second fixtures 60 face upward.

[0054] When the first fixture 30 faces forward, the second fixture 60 rotates with the cutter assembly 50 to drive the second tape roller 2a to rotate accordingly and disengage from the first fixture 30.

[0055] When the clamping openings of the two second fixtures 60 face upward, the first fixture 30 descends to place the second tape roller 2a in the second fixture 60.
