[0033] Firstly, the keys are placed on the feeding rod 44, the side of the keys needing to be sprayed faces upwards, the position of the keys is adjusted along the length direction of the feeding rod 44 until the keys are directly above the specified position on the spraying table top 1, then the lifting assembly 45 drives the feeding rod 44 to descend, when the feeding rod 44 passes through the support rod 41, the two support rods 41 are pushed to the two sides again, then the feeding rod 44 gradually descends below the support rod 41, in this process, the keys gradually move to the support rod 41 as the feeding rod 44 descends, then the keys are supported by the support rod 41, the lifting assembly 45 drives the feeding rod 44 to continue to descend until the feeding rod 44 descends to the starting point, at this time, the keys are moved to the specified position on the support rod 41, finally, the spraying assembly 3 is controlled to spray the keys on the spraying table top 1, the ink below the keys will not be blocked by the keys, after the spraying is completed, the keys on the spraying table top 1 are taken away, waiting for the next spraying, repeating the above process, since the feeding rod 44 is blocked by the support rod 41 and the inclined plate 42 during the spraying process, the upper surface thereof will not be stained with ink, and the keys move on the feeding rod 44 without ink on the upper surface during the position adjustment, which can adjust the position of the keys before the keys move to the spraying table, then the keys are directly moved to the specified position on the spraying table, preventing the keys from being placed on other positions on the spraying table, or the keys moving on the spraying table contacting the ink on the spraying table, reducing the possibility of the position of the bottom of the keys not needing to be sprayed being stained with the ink on the spraying table.

[0034] In order to achieve the purpose of driving the feeding rod 44 to ascend and descend, referring to Figure 3 , the lifting assembly 45 comprises a cylinder 451 installed inside the lifting groove, the top of the cylinder 451 is fixedly connected with a lifting plate 452, one end of the plurality of feeding rods 44 is fixedly connected with the lifting plate 452, in use, the cylinder 451 drives the lifting plate 452 to ascend and descend, and in turn drives the plurality of feeding rods 44 connected with the lifting plate 452 to ascend and descend, achieving the purpose of driving the feeding rod 44 and the keys above the feeding rod 44 to ascend and descend.

[0035] In order to achieve the purpose of pushing the support rod 41 to ascend, referring to Figure 4 and Figure 5The pushing-up assembly 43 comprises a side plate 431 fixedly connected with the inclined plate 42, and a spring 432 fixedly connected between the side plate 431 and the extension groove. In use, the spring 432 pushes the side plate 431 obliquely upwards, and drives the support rod 41 to move obliquely upwards until the two support rods 41 in the same horizontal groove abut against each other and block each other, so that the support rod 41 cannot continue to rise. When the discharging rod 44 passes between the two support rods 41 from above or below, the discharging rod 44 extrudes the two support rods 41 from between the two support rods 41, so that the two support rods 41 move to two sides. The support rod 41 pushes the side plate 431 to extrude and contract the spring 432, until the discharging rod 44 passes between the two support rods 41 and no longer contacts the support rod 41. The spring 432 pushes the support rod 41 to rise obliquely upwards again.

[0036] In order to facilitate the placement of the keys on the discharging rod 44, and to meet the purpose that the discharging rod 44 can push the support rod 41 to two sides, with reference to Figure 5 , the top of the discharging rod 44 is a flat surface, and the two ends of the discharging rod 44 are sleeved with arc-shaped plates 5. One end of the arc-shaped plate 5 extends to between the support rod 41 and the discharging rod 44, and the two sides of the arc-shaped plate 5 are provided with bolts 6 extending to the inside. In use, since the top of the discharging rod 44 is a flat surface, the keys can be placed on the discharging rod 44 without falling off. However, at this time, the discharging rod 44 cannot pass between the two support rods 41 when it is raised from below the support rod 41, so the discharging rod 44 is blocked by the support rod 41 and cannot be raised. The arc-shaped plate 5 installed on the top of the discharging rod 44 can make the upper surfaces of the two ends of the discharging rod 44 still be arc surfaces, and the middle of the discharging rod 44 is a flat surface for placing the keys. In this way, when the discharging rod 44 is raised, the arc-shaped plate 5 is first moved between the two support rods 41, and then pushes the two support rods 41 to two sides during the raising process, so that the keys can be placed more conveniently on the discharging rod 44, and the discharging rod 44 can pass between the two support rods 41 smoothly.
