The main channel 10, the auxiliary channel 20 and the air flow channel 50 all extend along the length direction to form a long and narrow channel, the speed reducing plates 30 are correspondingly arranged along the extending direction of the main discharge hole 12, the outer sides of the speed reducing plates 30 on two sides are respectively connected with a plurality of telescopic rods, one ends of the telescopic members are rotationally arranged on the cross rods 61 and cannot move, the telescopic members and the speed reducing plates 30 are connected through two circular rings, so that the telescopic members can control the opening and closing degree of the speed reducing plates 30 through telescopic operation to be electromagnet or electric pull rods and other parts. The controller 40 may also be configured to operate in other manners, such as a motor and a cam to open or close the speed-reducing plate 30. The opposite sides of the two speed reducing plates are the inner sides, and the opposite sides are the outer sides.
The included angle of one side of the speed reducing plate 30 to the vertical direction ranges from ten degrees to thirty degrees.

The velocity of the air flow channel 50 acting on the fiber is greater than the velocity of the fiber falling down itself, so that the velocity of the fiber after being driven by the air flow is not greater than the velocity of the air flow, and after the air flow enters the main channel 10 in the area below the auxiliary feed port 21, the velocity of the air flow is as follows because the width of the main channel 10 becomes largeWherein a is the width of the main channel 10 above the secondary discharge opening 22, b is the width of the main channel 10 below the secondary discharge opening 22, and the mixing speed of the fiber and the particle material is not more thanThe height of the speed reducing plate 30 in the vertical direction isWhere l is the height of the speed-reducing plate 30, α is the angle between the speed-reducing plate 30 and the vertical, the angle alpha is chosen to be 30 ° for the calculation of the shortest time, and the fastest time t for the air flow to pass through the area of the speed-reducing plate 30 without a change in speed isBecause the openings between the speed reducing plates 30 are enlarged, the time for the air flow or the mixed material to pass through the speed reducing plates 30 is less than the time t, so that the speed reducing plates 30 can be opened and closed once within the time t, and all the mixed materials passing through the area of the speed reducing plates 30 can be scattered and split, thereby achieving the effect of enabling the mixed materials to be mixed more uniformly.
As shown in fig. 3 and 4, opposite sides of the two speed reduction plates 30 are provided with a plurality of protrusions 31. When the air stream entrains fibers and particles flowing out of the main discharge port 12 of the main channel 10 and passes through the area between the speed reduction plates 30, wall-attached flow is formed on the near wall surface of the speed reduction plates 30 due to the viscosity of the air stream. The coanda flow will develop and enhance and will tend to randomly peel off as the wall of the velocity reduction plate 30 travels downward, creating random turbulence and thus affecting the uniformity of the underlying product. In order to eliminate the influence of wall attaching flow, this patent is provided with a plurality of convex protruding 31 on the speed-down board 30, also can only set up in the upper half section, through protruding 31 to the interference effect of wall attaching flow, let wall attaching flow just be destroyed by the interference at the initial development stage, peel off in advance, avoid producing bigger disturbance after its development reinforcing to the homogeneity of final product has been guaranteed.

The upper end of the speed reducing plate 30 is provided with a plurality of ventilation holes 32. After the mixed material formed by the fibers and the particles is sprayed out from the main discharge hole 12, in order to enable the mixed material to be rapidly depressurized in the area of the speed reducing plate 30, the vent holes 32 are formed in the upper end of the speed reducing plate, so that the outside air can enter the area between the speed reducing plates from the vent holes 32, a better depressurization effect is achieved, and the mixed material is dispersed more uniformly.
The air vent 32 is internally provided with a sliding rod 33 extending along the axial direction, a fixed rib 34 extends from one end of the inner side of the sliding rod 33 to the inner wall of the air vent 32, a circular sealing disc 35 is arranged at one end of the outer side of the sliding rod 33, an annular sealing disc 36 is arranged at one end of the outer side of the air vent 32, the diameter of one end of the outer side of the air vent 32 is smaller than that of one end of the inner side, the sliding rod 33 is sleeved with a sliding disc 37, the sliding disc 37 is concentric and is used for sliding along the sliding rod 33, the diameter of a central circular hole of the sliding disc 37 is smaller than that of the sealing disc 35, the diameter of an outer ring of the sliding disc 37 is larger than that of an inner hole of the sealing disc 36 and smaller than that of the air vent 32, when the sliding disc 37 moves to one end of the outer side of the sliding rod 33, the air vent 32 can be blocked by the sliding disc 37 through air flow.
