[0033] In the above technical solution of the utility model, the feeding device optimizes its own structure to adopt at least two conveyor belts 321 for auxiliary feeding, and these conveyor belts 321 are arranged on the mounting bracket 31 in sequence along the vertical direction to control the height difference between two adjacent conveyor belts 321, so as to effectively adapt to FEP heat shrink tubes of different specifications, and the above conveyor belts 321 all extend along the feeding direction of the feeding wheel 2 to enhance the preload force of the FEP heat shrink tube feeding.

[0034] In actual use, the FEP heat shrink tube on the feeding wheel 2 can be fed into the conveying drive mechanism 3 for traction feeding by controlling the tension through the tension control mechanism, and the tension control mechanism is specifically controlled by the magnetic powder brake to control the rotation axis to control the tension during feeding and ensure uniform speed and force feeding; the FEP heat shrink tube can be specifically fed into the gap between two adjacent conveyor belts 321, so as to use the conveyor belt 321 on the conveying drive mechanism 3 for pre-tightening, thereby enhancing the feeding effect of the FEP heat shrink tube. In addition, considering the needs of different application situations, the operator can set the height of the conveyor belt 321 on the mounting bracket 31 according to the specific use requirements to adjust the position of the conveyor belt 321, so as to more reasonably convey the FEP heat shrink tube.
