[0032] like Figure 1 , Figure 3 As shown, a specific implementation of the roller plating scattered needle spray device provided in this embodiment includes a shell 1, a roller 2 is rotatably arranged on the shell 1, and an opening is arranged on one side of the roller 2. The roller 2 can rotate under the drive of the driving member 3, and the driving member 3 is a motor; the spray device has a plurality of nozzle groups for spraying liquid; a connecting rod assembly, wherein the first end of the connecting rod assembly is rotatably connected to the spray device, and the position of the connecting rod assembly away from the first end is rotatably connected to the shell 1; a driving device 5, which is fixedly arranged on the shell 1, and the driving device 5 is a motor. The driving device 5 is rotatably connected to the second end of the connecting rod assembly, and the driving end of the driving device 5 is eccentrically connected to the connecting rod assembly. When the driving device 5 rotates, because the driving end of the driving device 5 is eccentrically connected to the connecting rod assembly, because the connecting rod assembly will rotate around the rotation point connected to the shell 1, thereby driving the spray device at the first end of the connecting rod assembly to approach or move away from the roller 2. The driving device 5 drives the connecting rod assembly to move, so that the liquid sprayed by the spray device evenly washes the inner wall of the drum 2 from top to bottom, driving the scattered needles on the inner wall of the drum 2 to fall off during the washing, thereby improving the secondary electroplating or mixing of materials caused by incomplete manual cleaning of the drum 2 and reducing the labor intensity of manual work. In addition, as an alternative embodiment, the driving device 5 is a cylinder, and the driving end of the cylinder is rotatably connected to the connecting rod assembly.

When the connecting assembly rotates, the connecting rod 10 is driven to reciprocate in the vertical direction, so that the liquid sprayed by the spray device can clean the scattered needles on the inner wall of the drum 2. In addition, as a replaceable embodiment, the spray device can also be slidably arranged on the shell 1. In addition, as a replaceable embodiment, only the mounting seat 9 can be arranged, and the mounting seat 9 is rotatably connected to the connecting rod assembly.

[0036] like Figure 2 As shown, in this embodiment, the upper end surface of the mounting seat 9 is provided with an arc surface 11 along the length direction, and the nozzles in each nozzle group are arranged in an array according to the circumferential direction of the arc surface 11, so that the spraying direction of each nozzle is different, and each side wall of the drum 2 can be covered, thereby improving the cleaning effect.

[0040] Working principle of the roller plating scattered needle spray device: the driving member 3 drives the roller 2 to rotate, so that the roller 2 stops rotating when the opening is facing downward. At this time, most of the materials in the roller 2 fall into the lower hopper 13 due to gravity, but there is still a part of the material adhering to the inner wall of the roller 2. The driving member 3 is started, and since the third swing rod 8 and the driving end of the driving member 3 are eccentrically arranged, the driving member 3 will drive the third swing rod 8 to move, thereby raising or lowering one end of the first swing rod 6, so that the other end of the first swing rod 6 is lowered or raised, driving the spray device to reciprocate in the vertical direction, thereby washing the materials on the inner wall of the roller 2 into the lower hopper 13 below.
