[0069] In one embodiment, the spraying chamber 1 further includes a baffle 12 provided on the chamber 11. The conveying device 3 includes a first conveying mechanism 31, a second conveying mechanism 32, a first occupancy switch 33, a second occupancy switch 34, a second driving mechanism, a third occupancy switch 35, and a fourth occupancy switch 36. Among them, the implementation manners of the first conveying mechanism 31, the second conveying mechanism 32, the first occupancy switch 33, the second occupancy switch 34, and the second driving mechanism are the same as those in the above embodiment and will not be elaborated here.

Then the controller 7 controls the first conveying mechanism 31 to start, and the first conveying mechanism 31 conveys the workpiece 10 to be painted onto the second conveying mechanism 32. When the workpiece 10 to be painted completely passes the second occupancy switch 34, the second occupancy switch 34 transmits a closing signal to the controller 7. The controller 7 controls the second driving mechanism to drive the baffle 12 to move in the opposite direction to close the spraying chamber 1. When the baffle 12 moves to the second position, the closing detection sensor 38 senses the position of the baffle 12, determines that the baffle 12 of the spraying chamber 1 has been fully closed, and transmits a closing-in-place signal to the controller 7. The controller 7 controls the second driving mechanism to drive the baffle 12 to move in the opposite direction to close the spraying chamber 1. Then the controller 7 controls the exhaust device 5, the spraying device 2, the heating device 4, and the purification device 6 to clean the ash, paint, dry, and purify the exhausted air of the workpiece 10 respectively. After the above work is completed, the second conveying mechanism 32 conveys the painted workpiece 10 to the second occupancy switch 34. The second occupancy switch 34 transmits an opening signal to the controller 7. The controller 7 controls the second conveying mechanism 32 to stop moving and controls the second driving mechanism to drive the baffle 12 to move to open the spraying chamber 1.

The controller 7 controls the second conveying mechanism 32 to start, and the second conveying mechanism 32 conveys the workpiece 10 to be painted onto the first conveying mechanism 31 and completes the conveyance of the workpiece 10 through the first conveying mechanism 31. When the workpiece 10 completely passes the first occupancy switch 33, the first occupancy switch 33 transmits a closing signal to the controller 7. After the closing detection sensor 38 detects that the baffle 12 is in the second position, a closing-in-place signal is transmitted to the controller 7. The controller 7 controls the second driving mechanism to drive the baffle 12 to move in the opposite direction to close the spraying chamber 1.

[0075] Among them, the baffle 12 in this embodiment can be one baffle 12 or two baffles 12. For example, Figure 2 In [the case where], two baffles 12 are provided on the spraying chamber 1, and the two baffles 12 form the double-leaf doors of the spraying chamber 1. At this time, the first position is at both ends of the entrance of the spraying chamber 1, and the second position is in the middle of the entrance of the spraying chamber 1. It can be understood that the spraying chamber 1 can also be provided with one baffle 12. At this time, the first position is at one end of the entrance of the spraying chamber 1, and the second position is at the other end of the entrance of the spraying chamber 1.

One end of the second air duct communicates with the chamber 11, and the other end of the second air duct communicates with the end of the first air duct 51 away from the fan 52.

[0077] In this embodiment, by providing a plurality of second air ducts at the bottom, top and / or around the spraying chamber 1, the dust cleaning effect can be improved, the effect of extracting fluff and dust can be enhanced, and the paint can be dried and cured more quickly after painting; the plurality of second air ducts communicate with the first air duct 51, and impurities can be discharged through the first air duct 51.

[0078] In summary, the paint spraying equipment of the present application can automatically spray the roving trolley used in glass fiber production, solve the problem of the roving trolley rusting and reducing its service life, reduce the labor intensity at the same time, and improve the work efficiency compared with manual spraying.
