The embodiment mainly aims at the winding operation and the unwinding in the staple production process, and adopts a double-reel synchronous winding mechanism for operation in order to improve the production efficiency, and the structure of the double-reel synchronous winding mechanism is shown in fig. 1 to 4. The double-reel synchronous winding mechanism mainly comprises a rack 9, staple strips 10 are conveyed outwards through an unwinding mechanism arranged on the rack 9, and a winding mechanism is arranged at the tail end of the rack 9. In order to improve the production efficiency, two groups of staple strips are produced simultaneously on a production line, so that two groups of staple strips are conveyed by the unwinding mechanism, and the linear velocities of the two groups of staple strips are consistent, so that two reels in the winding mechanism are required to wind the two groups of staple strips respectively. The front end of the unwinding mechanism in this embodiment is usually connected to a wire splicing link, and the feeding linear speed during wire splicing is usually consistent with the output linear speed of the unwinding mechanism in this embodiment, so that during the material winding operation performed on the unwinding mechanism, it is necessary to ensure that the linear speed of the material during winding is also consistent with the linear speed of the material output by the unwinding mechanism (hereinafter referred to as the unwinding linear speed). If the winding linear velocity is less than the unwinding linear velocity, the staple strips 10 are stacked on the front part of the reel; if the winding linear velocity is greater than the unwinding linear velocity, the staple strip 10 is stretched, thereby affecting the production operation link at the front end of the unwinding mechanism.

The sleeve 141 is sleeved on the third rotating shaft 13, a fastening bolt 143 for fastening the sleeve 141 on the third rotating shaft 13 is disposed on the sleeve 141, and an insertion block 142 is disposed at one end (end close to the connecting shaft sleeve 16) of the sleeve 141. The sleeve 141 is pushed towards the second reel 12, the insert 142 is inserted into the slot 161, and the bolt 143 is tightened to fix the second reel 12 and the third shaft 13 together, so that the two reels can be synchronously wound by a belt transmission mechanism.

The more common control methods are: the rotating shaft of the reel is driven by a driving motor independently, a rotary encoder is arranged on the motor shaft to acquire the rotating speed, and the rotating speed of the reel is adjusted by a feedback pulse signal input to the driver. Such a drive structure is relatively complex and also expensive to manufacture. In this embodiment, the speed of rotation of the two reels is adjusted by using a speed-reducing belt transmission mode. Two groups of staple strips 10 conveyed out of the unwinding mechanism are respectively wound on two reels, when materials on the two reels are less, the winding diameter of the reels is smaller, the belt pulley drives the third rotating shaft 13 to rotate under the action of static friction force, and at the moment, because the materials on the reels are less, the load of the belt 8 is smaller, and the belt 8 can drive the reels to rotate at a higher speed.
