The invention belongs to the technical field of spraying, and relates to a
coating spraying process and spraying equipment for waterproof cloth. The equipment comprises a storage box, a flow guide plate, a baffle plate, a supporting
assembly, a guide roller I, a spraying mechanism, a
drying box and a cleaning mechanism. According to the spraying mechanism, continuous suction and spraying of paint are achieved through
reciprocating motion of a
piston pipe and a
piston block, a spray head is obliquely arranged and rotates along with paint pressure, and the spraying range is enlarged; a containing cavity is formed by the guide plate and the baffle plate and is matched with the
backflow opening to realize cyclic utilization of the
coating; hot air of the
drying box is introduced into the fixed base plate through the suction fan and discharged through the air holes to form a protective air curtain, and
coating escape is reduced; and the cleaning mechanism drives a knocking strip to periodically shake off redundant paint through a
cam. The process comprises the steps of cloth guiding, rotary spraying, air curtain protection, shake-off cleaning and synchronous
drying. The problems that existing equipment is uneven in spraying, paint is wasted and the environment is polluted are solved, and the coating uniformity, the paint
utilization rate and the production cleanliness are improved.
