The first rolling mechanism 4 and the second rolling mechanism 5 are mechanically connected to the rotating shaft of the motor 6. The rotating shaft of the motor 6 can be connected to the first rolling mechanism 4 and the second rolling mechanism 5 via a transmission chain. The first rolling mechanism 4 and the second rolling mechanism 5 rotate at the same speed. The cutting mechanism 3 is connected to the piston rod of the cylinder 2 and is movably mounted between the first rolling mechanism 4 and the second rolling mechanism 5, moving vertically on the transmission table 1. The first rolling mechanism 4 and the second rolling mechanism 5 are provided with a plurality of guide members 8 for guiding the movement of the LED light strip. The guide members 8 and adjacent guide members 8 form a receiving groove 7, which is used to receive the LED light strip moving on the transmission table 1. Each receiving slot 7 accommodates one LED light strip. Guides 8 on both sides of the receiving slot 7 roll along the sides of the LED light strip to move it forward. During the movement of the LED light strip, the cutting mechanism 3 moves downward via the cylinder 2 to cut the LED light strip. The cutting structure is located between the first rolling mechanism 4 and the second rolling mechanism 5, which improves the stability of the LED light strip during movement and ensures the accuracy of cutting. The second rolling mechanism 5 is located behind the cutting mechanism 3, so that the cut LED light strip can also be effectively guided.
