Further, the support 34 is connected to the frame 2 , the end of the connecting rod 35 fixed on the support 34 is welded to the slider 32 , and the compression spring 33 fits on the connecting rod 35 and contacts the slider 32 .

Further, adjustable tensioners 7 are provided on the conveying devices.

The beneficial effects of the utility model: 1. Realize the convenient transportation of the rubber belt, save labor force, and have a high degree of automation.

2. The device of the utility model can realize frequency conversion and speed regulation by adjusting any one of the driving motor or the driving blade motor, thereby ensuring the fixed-length cutting of the rubber belt.

3. The cutter assembly is installed on the sliding assembly. During the cutting process, the shear stress generated when the blade presses against the rubber belt is buffered by the slider pressing the spring, thereby offsetting the shear stress, and the generated shear stress is relatively small. Small, there will be no large up and down fluctuations.

4. The pressure roller of the device of the utility model leans against the conveying rubber belt and rotates through the force of the rubber belt, effectively preventing the rubber belt from warping during the cutting process and reducing the error of fixed-length cutting.
