The output shafts of the pulley motor 1 and the eccentric motor 3 are installed on the bottom plate 5 through the pulley 2, the pulley 2 is installed on the output shaft end of the pulley motor 1, the eccentric wheel 4 is installed on the output shaft end of the eccentric motor 3, the bottom plate 5 is square, the pulley motor 1 and the eccentric motor 3 are installed on the same side of the bottom plate 5, and the pulley motor 1 and the eccentric motor 3 are on the diagonal line of the bottom plate 5, and the frame 6 is installed on the bottom plate 5. The frame 6 is composed of four connecting plates, and the connecting plates are connected by connecting pieces. The frame 6 is connected to the bottom plate 5 in a detachable manner. The tensioning assembly is installed between the pulley 2 and the eccentric wheel 4. The PET-PP belt enters from one side of the frame 6 and contacts the pulley 2 and extends from the other side of the frame 6. The eccentric wheel 4 intermittently drives the tensioning assembly to approach the pulley 2 so that the PET-PP belt is tightly attached to the pulley 2. The rotation of the pulley 2 can drive the PET-PP belt to move and send the PET-PP belt to the next workstation. A reset spring 7 is provided in the tensioning assembly, and the reset spring 7 keeps the tensioning assembly in contact with the eccentric wheel 4.

[0021] In an embodiment provided by the utility model, a belt inlet 61 is provided at the upper end of the frame 6, and the belt inlet 61 is connected to a belt inlet channel 62, and the bottom end of the belt inlet channel 62 is close to the pulley 2. A belt outlet 63 is provided at the right bottom end of the frame 6. The PET-PP belt enters the belt inlet channel 62 from the belt inlet 61, and then extends from the bottom end of the belt inlet channel 62 and is wound around the pulley 2.
