A plurality of electric rollers 2 are installed at an equal distance from the front to the back at the lower end of the spray painting rack 1. Two suction cylinders 6 are provided, and the two suction cylinders 6 are installed through the front sides of the left and right ends of the spray painting rack 1. The adsorbent storage box 7 is installed at the front side of the lower end of the spray painting rack 1. Two filter tanks 10 are provided, and the two filter tanks 10 are respectively located at the left and right ends of the spray painting rack 1. The upper end of the adsorbent storage box 7 is connected to the two filter tanks 10 through two suction pipes 9. The two filter tanks 10 A first outer screw barrel 12 is screwed on the upper end of the interior through a thread, a sealing ring 11 is fixed on the upper ends of the two first outer screw barrels 12, a second outer screw barrel 13 is fixed on the upper ends of the two sealing rings 11, an activated carbon plate 14 is horizontally installed in the two second outer screw barrels 13, a disposable cover 15 is screwed on the outside of the two second outer screw barrels 13 through a thread, an exhaust fan 16 is installed in the two disposable covers 15, and a filter screen 17 is installed on the air outlet end of the two disposable covers 15. This design solves the problem that the original device cannot suck out the scattered paint droplets during the spraying process, which is easy to endanger the personal safety of the surrounding production line personnel.

[0019] As the first embodiment of the utility model: a feed pump 3 is installed at the upper end of the paint spraying rack 1, an electric push rod 4 is longitudinally installed at the upper end of the interior of the paint spraying rack 1, and a paint spraying head 5 is installed at the movable end of the electric push rod 4, and the paint spraying head 5 can be driven to move in the up and down directions by the added electric push rod 4. The feed pump 3 is connected to the paint spraying head 5 through a feed hose, and the added feed pump 3 can feed the paint spraying head 5 through the feed hose.

[0020] The openings of the two suction cylinders 6 are both facing the front multiple electric rollers 2. The two added suction cylinders 6 can be used to suck the paint droplets scattered from the surface of the plastic parts sprayed at the upper ends of the front multiple electric rollers 2. An adsorbent is provided at the lower end of the adsorbent storage box 7. The upper sides of the left and right ends of the adsorbent storage box 7 are respectively connected to the two suction cylinders 6.
