Detailed Description
Referring to fig. 1, the web of the deck of the die cutting machine of the present invention operates according to the following process:
in the tape-walking process, coiled materials sequentially pass through a motor output wheel 1, a first tensioning wheel 2, a first synchronizing wheel 3, a second synchronizing wheel 4, a third synchronizing wheel 5, a fourth synchronizing wheel 6, a fifth synchronizing wheel 7, a second tensioning wheel 8, a first output wheel 9 and a second output wheel 10 and then enter a die-cutting station 11 for die-cutting; wherein: the motor output wheel 1 is arranged on the motor output shaft, and the diameter of the motor output wheel is 10 cm; the diameter of the first tensioning wheel 2 is 10 cm; the diameter of the first synchronizing wheel 3 is 15 cm; the diameter of the second synchronizing wheel 4 is 20 cm; the diameter of the third synchronizing wheel 5 is 25 cm; the diameter of the fourth synchronizing wheel 6 is 30 cm; the fifth synchronizing wheel 7 has a diameter of 35 cm.

The diameter of the second tensioning wheel 8 is 20 cm, the diameter of the second tensioning wheel is reduced, and the phenomenon that the coiled material is broken due to overlarge curvature change in the process that the coiled material is directly transferred to the tensioning wheel with the coiled diameter of 10cm from the synchronous wheel with the coiled diameter of 35cm is avoided, so that a transition effect is achieved. The first output wheel 9 and the second output wheel 10 are used for guiding out the coil stock, and the diameters of the first output wheel and the second output wheel are both 10cm and are the same as those of the original device.
The utility model is favorable for releasing stress and recovering deformation of the coiled material, and the electric heating pipes are arranged in the first tensioning wheel, the second tensioning wheel and the first to fifth synchronous wheels, so that the surface temperature of the roller is improved by heating through the electric heating pipes.

Referring to fig. 2, the first synchronous pulley 3 is provided with an electric heating pipe 15, a uniform heat conducting layer 14, a roller body 13 and a wear-resistant heat insulating layer 12 from inside to outside. The resistance wire 17 and the thermocouple 16 are arranged in the tube body of the electric heating tube 15, the two ends of the resistance wire and the electrode of the thermocouple are led out of the tube body to form an external circuit element, the thermocouple has the temperature measuring function, and the temperature control effect is realized by connecting the thermocouple with a control element. The two ends of the roller body are provided with bearings 19, the outer ring of the bearing is fixed with the roller body by pins 18, the inner ring of the bearing is fixed with the electric heating tube, and the heating tube does not rotate in the rotation process of the roller.
