Cooling device for short fiber processing

The utility model discloses a cooling device for short fiber processing, which comprises a sleeve, the top end of the sleeve is fixedly connected with a top ring, the top end of the top ring is fixedly connected with a fiber feeding ring, two side walls of the top ring are respectively provided with a thin pipe in a penetrating way, one end part of each thin pipe is sleeved with an air inlet pipe, and the middle parts of the inner sides of the two air inlet pipes are respectively provided with a rotating plate; a cavity is formed in the top ring, a plurality of balls are movably embedded in the cavity, a plurality of clamping pipes penetrate through the bottom end of the top ring, and a rectifying cylinder is arranged in the sleeve. By arranging a series of structures, the situation that fibers deviate towards one side due to lateral air blowing is avoided, the probability of defects is reduced, the situation that the cooling speed is high or low due to the fact that the positions of the fibers are different
