More specifically, the bale dragging machine in the embodiment is further provided with a pressing block 40; a rotating shaft is formed at the central axis of the mirror supporting sheet 20; the pressing block 40 is arranged at the rotating shaft and is stacked on the belt wrapping disc.
In this embodiment, the pressing block 40 is arranged to enable the taping disk to be disposed on the same horizontal plane when being in a static state or a rotating state, so as to avoid the situation that the taping disk falls off from the rotating shaft during the rotating process, and further ensure the normal operation of the bag dragging machine.
Wherein, the pressing block 40 is also provided with a bearing; the bearing is sleeved outside the rotating shaft.
In the embodiment, the bearing may be used to reduce the friction between the pressing block 40 and the rotating shaft, i.e. the pressing block 40 may rotate freely.
Preferably but not limited, the rotating shaft is provided with a fixed ring, and the diameter of the fixed ring should be larger than the inner diameter of the bearing and smaller than the inner diameter of the taping disk, so that the normal installation of the taping disk can be ensured, the setting height of the pressing block 40 can be limited, the taping disk can only move between the mirror surface support plate 20 and the fixed ring, and the taping disk can be prevented from being separated from the mirror surface support plate 20 in the rotating process of the taping disk.
Preferably, but not limited to, the weight of the pressing block 40 is large enough to keep the taping disk on the same level during the rotation process due to the pressing action of the pressing block 40, and the normal rotation process of the taping disk is not affected.
More specifically, a brake is also included; the brake is fixedly connected with the middle shaft of the guide wheel 30 and used for controlling the rotating speed of the guide wheel 30.
In this embodiment, the tape is extended out of the tape reel and then contacts with the outer edge of the guide wheel 30, so that when the guide wheel 30 rotates, the tape and the outer edge of the guide wheel 30 will form friction to drive the tape to move, and meanwhile, the tape can move at different speeds due to the rotation speed of the guide wheel 30, so that the tension of the tape can be controlled by controlling the rotation speed of the guide wheel 30.
More specifically, the brake is an electromagnetic brake 50.

In this embodiment, the tension checker 80 provides both the fixing device for the flat belt 70 and the measuring device for detecting the belt tension, and in this embodiment, since the belt moves at the same speed, the flat belt 70 is driven to move, so that the tension on the flat belt 70 is detected, and the belt tension is converted.
In order to ensure that the flat belt 70 can be stacked on the wrapping belt, the positions of the first fixing column 61 and the second fixing column 62 are limited, if the first fixing column 61 and the second fixing column 62 are located on a vertical line between the tray and the guide wheel 30, the flat belt 70 can completely cover the wrapping belt, and when the straight line where the first fixing column 61 and the second fixing column 62 are located passes through the guide wheel 30, the flat belt 70 can partially cover the wrapping belt.
