A conveyor belt 7 is set on the transmission shaft 6, and there are evenly distributed convex points on the conveyor belt 7. The transmission shaft 6 drives the conveyor belt 7 to rotate and is flush with the top of the fixed seat 5, and the roller 29 is connected to the frame 1 above the conveyor belt 7 through a bearing. The roller 29 rotates relative to the conveyor belt 7 by meshing with the drive shaft gear of the motor, pushing the rubber 8 placed on the conveyor belt 7 toward the fixed seat 5, and gradually pulling the rubber 8 on the winding roller 10 into the fixed seat 5.

[0034] Reference Figures 2 to 4 , a connecting groove 13 is opened on the knife seat 4, and the connecting frame 11 is set below the knife seat 4. The bottom of the connecting frame 11 is connected to a pressure roller 15 through a bearing, corresponding to the fixed seat 5, and a connecting column 12 is welded on the connecting frame 11.

The operator then places the front end of the calendered rubber 8 onto the conveyor belt 7. The motor drives the transmission shaft 6 to begin rotating, which in turn drives the conveyor belt 7. The roller 29 on the frame 1 begins to rotate relative to the conveyor belt 7, transporting the rubber 8 toward the fixed seat 5. After the rubber 8 reaches the fixed seat 5, the driving member 3 drives the knife seat 4 downward, and the connecting frame 11 at the bottom of the knife seat 4 moves downward synchronously. The pressure roller 15 on the connecting frame 11 presses the rubber 8, and the knife 41 cuts the rubber 8. The knife seat 4 then moves upward, the knife 41 is lifted, and the pressure roller 15 releases the rubber 8, ensuring that the cutting interval is the same each time, ensuring that the width difference of the rubber strip is minimized. The cut rubber strips fall onto the detection part 17 on the support plate 16, and the detection part 17 detects the rubber strips. The unqualified rubber strips are pushed to the frame below the frame 1 by the driving part 3 19 driving the push plate 2 21. The qualified rubber strips are pushed to the conveyor belt 2 27 by the driving part 2 18 pushing the push plate 1 20. The transmission shaft 26 drives the conveyor belt 2 27 to rotate and send the qualified rubber strips to the collection frame, thereby improving the cutting efficiency of the rubber strips.
