Bag-cage skeleton and paint spraying system thereof

The invention provides a bag-cage skeleton and a paint spraying system thereof. In the prior art, the conventional paint sprayer does not have a delivering structure, a blowing and washing structure, a drying structure, and a feeding structure; thus a bag-cage skeleton has to be delivered, blown, washed, dried, and fed through artificial operation; the operation is complicated, and the extremely-long skeleton is inconvenient for delivering. The provided bag-cage skeleton comprises a first skeleton body and a second skeleton body; the first skeleton body and the second skeleton body are connected through a detachable structure; the length ratio of the first skeleton body to the second skeleton body is 1:1 or 2:1; the first skeleton body and second skeleton body are both covered by a layer of protective paint, and the paint is sprayed on the first skeleton body and second skeleton body through a paint spraying system. The bag-cage skeleton also comprises a paint spraying system. The bag-cage skeleton and paint spraying system have the advantages of convenient transportation and paint spraying.
