Since the cloth passes around the floating roller 63 along the bottom of the floating roller 63, the gravity of the floating roller 63 will be applied to the cloth as a tensioning force. When the movement speed of the cloth belt is high and the requirement on the tension force is high, the floating roller 63 moves upwards along the sliding rod 62; when the cloth belt moves slowly and the tensioning force requirement is low, the floating roller 63 moves downwards along the sliding rod 62. The tension force in the cloth belt can be adjusted through the gravity of the floating roller 63, so that the cloth belt keeps a smooth and tight motion state in the device.
Optionally, for improving the adaptability of the tensioning mechanism and meeting the requirement of a larger tensioning force, the tensioning mechanism may include a counterweight roller 64, and the counterweight roller 64 is slidably disposed on the sliding rod 62 and located above the floating roller 63. The support frame is provided with a limiting piece matched with the counterweight roller 64, and the lowest height of the counterweight roller 64 is limited through the limiting piece. Optionally, the limiting member may be a hook disposed on the supporting frame. When the floating roller 63 can provide enough tension force, the counterweight roller 64 can be hung on the hook; when the self gravity of the floating roller 63 cannot meet the tensioning requirement of the cloth belt, the floating roller 63 can move upwards and abut against the counterweight roller 64, and the gravity of the counterweight roller 64 is applied to the cloth belt through the floating roller 63, so that the tensioning mechanism can apply larger tensioning force to the cloth belt.
The inventor finds that the cloth roll has larger self gravity in the actual working process, so that the cloth roll is influenced by inertia when rotating to release cloth. When the yardage roll excessively rotates due to inertia, a large number of cloth belts are separated from the yardage roll, and the excessive cloth releasing phenomenon is easy to occur at the moment. After the phenomenon of excessive cloth release, the cloth belt inside the device can be wound to fold the edge, and the working quality of subsequent equipment is seriously affected.
In order to avoid the phenomenon, a speed reducing belt 82 and a speed reducing mechanism are arranged in the device, the rotating speed of the cloth roll positioned at the cloth releasing station can be limited through the speed reducing belt 82, and the rotating speed of the cloth roll positioned on the cloth roll support 11 can be limited through the speed reducing mechanism.

When the cloth unwinding device works, the speed reducing belt 82 is placed on a cloth roll in a cloth unwinding state, and the rotation speed of the cloth roll can be limited by using the friction between the belt and the cloth roll, so that the phenomenon of excessive cloth unwinding of the cloth roll is avoided.
The structure of the speed reducing mechanism can be schematically shown in fig. 5, and as shown in the figure, the speed reducing mechanism includes: a reduction seat 111 and a reduction ring 112. The speed reducing seat 111 is arranged on the cloth roll bracket 11, the speed reducing ring 112 is arranged at the end part of the central bearing shaft of the standby cloth roll, and the speed reducing seat 111 is provided with an accommodating groove for accommodating the speed reducing ring 112. When the stand-by yardage roll is placed on yardage roll support 11, inside holding tank was arranged in to speed reduction ring 112, can restrict the slew velocity of stand-by yardage roll through the frictional force of speed reduction ring 112 and holding tank, avoided the stand-by yardage roll to appear excessive pivoted condition after getting into and putting the cloth state.
The working process of the above scheme is described as follows:
the method comprises the following steps: the cloth roll holder 11 is filled with a cloth roll to be used and put into a cloth unwinding state. Subsequently, the support bracket 52 is removed and the drive motor 41 is started, and the roll is lifted to the unwinding station by means of the lifting plate 3.
Step two: a new reserve roll is loaded into the roll holder 11 and the ends of the tapes of this roll are fixed to the stitching platform 54. Next, an adhesive is applied to the top surface of the tape and the support base 52 is mounted to the initial position.
Step three: when the yardage roll at the cloth unwinding station is about to be used up, the action cylinder 531 is started, so that the standby yardage roll and the yardage roll at the cloth unwinding station are spliced. The support block 52 is then removed and the central support shaft at the lay-out station is removed.
Next, the above-described steps one to three are repeated, so that the present apparatus can continuously supply the tape supply to the subsequent apparatus.
The following explains the effects of the above scheme:
