[0035] Reference Figure 1-2The storage device 7 includes a telescopic rod 71 and a third connecting block 72. The telescopic rod 71 includes a sleeve 711 and an inner rod 712. One end of the sleeve 711 is fixedly connected to the second support plate 12.

[0036] Reference Figure 1 -,3. The feeding device 2 is correspondingly provided with a locking device 8, which is used to lock the material 20 between the first limiting roller 22 and the feeding roller 21.

When it is necessary to release the temporary locking of the material 20, the armrest rod 83 is rotated to separate the cushion 82 from the material 20.

[0037] The implementation principle of the loading rack for convenient material connection of the electroplating production line in the embodiment of the present application is as follows: when the loading rack 1 is used to load the electroplating production line 10, the material 20 on the spool 9 is first passed through between the first limiting roller 22 and the loading roller 21, passed through the first roller 611, the counterweight roller and the second roller 621, and finally passed through between the second limiting roller 32 and the discharging roller 31 to the electroplating production line 10. During the process of continuous electroplating of the material 20 by the electroplating production line 10, the material 20 passes through the first roller 611, the counterweight roller and the second roller 621. 11, the gravity block 74 exerts a downward gravity on the third connecting groove 721 under its own gravity. At this time, the inner rod 712 moves downward along the sleeve 711, and the gravity roller 73 moves downward at the same time. The gravity roller 73 drives the material 20 to move downward, and the material 20 is transmitted to the second roller 621 via the gravity roller 73. At this time, the length of the material 20 between the first roller 611 and the second roller 621 increases, achieving the effect of storing part of the material 20; as the spool 9 continues to input the material 20 into the upper feed roller 21 0, when the material 20 in the spool 9 cannot meet the material 20 input to the upward feed roller 21, the handrail 83 is rotated at this time, and the handrail 83 rotates to drive the locking rod 81 fixedly connected to the handrail 83 to move into the locking groove 30 until the soft pad 82 abuts against the material 20, completing the temporary locking of the material 20 at the feed roller end. At this time, as the electroplating production line 10 continues to operate, the material 20 at the discharge roller 31 end is subjected to the pulling force of the electroplating production line 10, driving the inner rod 712 to be pulled upward through the gravity roller 73, and the inner rod 71 2 moves upward along the sleeve 711. During this process, the material 20 stored by the downward displacement of the gravity block 74 is continuously output to the electroplating production line 10 through the second roller 621 to the discharging roller 31. During this process, the new material 20 is inserted into the feeding roller 21, and the handrail 83 is rotated to separate the cushion 82 from the material 20, so that the temporary locking of the material 20 is released, and the new material 20 is continuously added to the feeding roller 21, thereby achieving the effect of continuously feeding the production line without stopping the machine and improving the work efficiency.
