Plant fiber product forming, trimming and spraying production line

The invention provides a plant fiber product forming, trimming and spraying production line which comprises a material arranging machine used for arranging plant fiber products to be sprayed to the same conveying direction and placing the plant fiber products on a conveying belt to be conveyed, and a variable-pitch spraying station comprising a variable-pitch taking and placing mechanism and a multi-station spraying machine. When the variable-pitch pick-and-place mechanism is in the variable-pitch state, the distance between a plurality of pick-and-place stations on the variable-pitch pick-and-place mechanism is increased, and when the variable-pitch pick-and-place mechanism is in the variable-pitch state, the distance between the plurality of pick-and-place stations of the variable-pitch pick-and-place mechanism is decreased; the distance-variable taking and placing mechanism in the distance-reducing state is driven to take the plant fiber products to be sprayed on the conveying belt and transfer the plant f
