[0028] like Figure 1-5As shown, to improve the slitting efficiency of the rubber strips, a slitting assembly is located on the top of the support frame 1, including a pressure cylinder 6 and a rotating cylinder 7. A top frame 8 is fixedly connected to the top of the fixed frame 5. The top frame 8 is T-shaped, and a cylinder 9 is vertically and fixedly connected to one side of the top frame 8. A connecting frame 10 is fixedly connected to the free end of the cylinder 9. The connecting frame 10 is U-shaped, and a brushless motor 11 is fixedly installed on the outer wall of the connecting frame 10. One end of the pressure cylinder 6 is rotatably connected to the inner wall of the connecting frame 10, and the other end is fixedly connected to the output end of the brushless motor 11. The top of the support frame 1 is fixedly... The device is fixedly connected to vertical plates 12 that are symmetrically distributed front and back. The rotating drum 7 is rotatably connected between the opposite side walls of the vertical plates 12. The pressure cylinder 6 is fixedly connected to evenly distributed slitting blades 13. The rotating drum 7 is provided with evenly distributed slitting grooves 14, which correspond to the slitting blades 13. The downward movement of the pressure cylinder 6 causes the slitting blades 13 to cooperate with the slitting grooves 14 to pre-slit the rubber. The operation of the servo motor 4 and the brushless motor 11 can make the discharge cylinder 3 discharge the rubber at a uniform speed. The rotation of the pressure cylinder 6, in conjunction with the rotating drum 7, can move the rubber laterally and perform continuous slitting operations on the rubber.

[0029] like Figure 1-6 As shown, to assist the lateral movement of the rubber strip, an auxiliary movement component is mounted on the fixed frame 5, including a rotating shaft 15.

[0031] In practical use, one end of the rubber is passed between the pressure cylinder 6 and the rotating cylinder 7. The control cylinder 9 extends, and the downward movement of the pressure cylinder 6 causes the slitting blade 13 to work with the slitting groove 14 to pre-slit the rubber. Then, the servo motor 4 and the brushless motor 11 are turned on simultaneously, and the feeding cylinder 3 releases the rubber at a uniform speed. The rotation of the pressure cylinder 6 causes the rubber to move laterally and can perform continuous slitting operations. After the rubber passes between the two guide cylinders 16, it is placed on the side plate 23.
