Reel feeding device and heat shrink tube dry expanding machine

The invention is suitable for the field of heat shrink tube dry expanding machines, and provides a reel feeding device and a heat shrink tube dry expanding machine. The reel feeding device comprises a lifting device, a damping device and a processing device, wherein the lifting device is used for lifting and lowering a reel; the damping device is used for applying damping of different magnitudes to the reel so as to adjust the rotating speed of the reel; and the processing device is used for controlling the work of the lifting device. The processing device controls the lifting device to lift and lower the reel, so that automatic feeding and discharging of the reel are achieved, and the labor cost is saved. Damping of different magnitudes is applied to the reel through the damping device so as to adjust the rotary feeding speed of the reel, and thus the stability of the rotary feeding process of the reel is guaranteed. 本发明适用于热缩管干扩机领域，提供了一种卷盘上盘装置以及热缩管干扩机，包括：升降装置，用于对卷盘进行抬升和下降；阻尼装置，用于对所述卷盘施加不同大小的阻尼，以调节所述卷盘的旋转速率；以
