As shown in fig. 18, 23 and 24, the winding device 73 includes a driving mechanism 731, a friction assembly 732 and a winding roller 733, wherein the driving mechanism 731 is in power connection with the winding roller 733 through the friction assembly 732, the driving mechanism 731 drives the friction assembly 732 to act to generate friction force, and the winding roller 733 is driven by the friction force to perform winding operation.

According to the embodiment, the unwinding roller is indirectly driven to unwind through the friction assembly, so that the winding speed of the winding roller can be limited, and the problem of tearing due to overlarge tension in the advancing process of the adhesive tape is avoided.

Under the action of the friction force generated by the friction assembly, the driving mechanism 731 and the winding roller 733 can keep synchronous rotation, so that the situation that the adhesive tape is torn due to overlarge tension caused by inertia over-rotation of the winding roller is avoided.

When the resistance of the wind-up roller 713 is smaller than the friction force generated by the friction component 732, the power plate 7321 drives the driving plate 7322 to rotate, and provides wind-up power to the wind-up roller 733 for wind-up operation; when the resistance of the wind-up roller 733 is greater than the friction force generated by the friction component 732, the power piece 7321 cannot drive the driving piece 7322 to rotate, and the wind-up power is stopped to be provided for the wind-up roller 733, so that the excessive tension of the adhesive tape caused by the over rotation of the wind-up roller is avoided.

When the rotational speed of the wind-up roller 733 is greater than the predetermined rotational speed, the resistance force received by the wind-up roller 733 is greater than the friction force generated by the friction assembly 732. That is, the rotational speed of the wind-up roller 733 is far greater than the rotational speed of the unreeling roller 713, and when the wind-up roller 733 is caused to over-rotate, the friction component 732 no longer provides power to the wind-up roller 733, and the rotational speed of the wind-up roller 733 gradually decreases to match with the rotational speed of the unreeling roller 713, so as to avoid excessive tension of the adhesive tape.

The rubberizing equipment of claim 4, wherein the pulley transmission mechanism comprises a driving wheel, a driven wheel and a synchronous belt, the driving wheel is sleeved on the damping shaft, and the damping shaft is driven by the driving mechanism to rotate so as to drive the pulley transmission mechanism to act and further drive the unreeling roller to rotate.

7. The rubberizing device of claim 2, wherein said transmission mechanism is a gear transmission mechanism.

8. The rubberizing device of claim 7, wherein said gear drive mechanism comprises a drive gear and a driven gear, said drive gear is sleeved on said damper shaft and engaged with said driven gear, said driven gear is connected to said unwind roller by a connector.

9. The rubberizing device of claim 1, wherein said drive mechanism is a motor.

10. The rubberizing device of claim 1, wherein a buffer roller is provided downstream of said unwind roller to prevent unwinding and stacking of said unwind roller.

11. The rubberizing device of claim 1, wherein said unwind roller is wound with tape.

12. The rubberizing apparatus of claim 1, wherein said drive mechanism and said wind-up roll rotate in synchronization under said frictional force generated by said friction assembly.

13. The rubberizing device of claim 1, wherein said driving mechanism drives said power plate to rotate, said driving plate being rotated by friction force generated by friction with said power plate.

14. The rubberizing apparatus of claim 1, wherein said wind-up roll is subjected to a resistance force greater than said friction force generated by said friction assembly when said wind-up roll is rotated at a speed greater than a predetermined speed.

15. The rubberizing device of claim 1, further comprising a detection device that detects full winding of the wind-up roll.

16. The rubberizing device of claim 15, wherein said detecting means is disposed above said wind-up roll for detecting whether said wind-up roll is full based on a height of wind-up on said wind-up roll.

17. The rubberizing apparatus of claim 16, further comprising a brake to brake said wind-up roll, said brake to brake said wind-up roll when said detection device detects that said wind-up roll is full.

18. The rubberizing apparatus of claim 17, wherein said brake is disposed between said band blade and said wind-up roll to brake said wind-up roll by abutting said band blade.

19. The tape application apparatus of claim 1, further comprising a first drive mechanism for driving the tape head to move in a horizontal direction and a second drive mechanism for driving the tape head to rise and fall.
