[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example 1

[0027] Spray velvet cloth spray velvet mold, such as Figure 1-Figure 2 As shown, it includes a fixed plate 4 and two blowing plates 2 arranged on the surface of the fixed plate 4, the surface of the blowing plate 2 is provided with an inlet and outlet assembly 1, and the blowing plate 2 and the inlet and outlet assembly 1 form a V-shaped channel 5, the outer surface of the blowing plate 2 is fixedly connected with an air inlet pipe 3, and the surface of the blowing plate 2 is provided with an air outlet hole 7, and the air outlet hole 7 is connected and communicated with the air inlet pipe 3.

[0028] When in use, the material enters through the inlet and outlet assembly 1, and then the gas enters the V-shaped channel 5 through the air inlet pipe 3. The gas blows the material discharged from the inlet and outlet assembly 1. Since the shape of the V-shaped channel 5 is V-shaped, the material discharged from the inlet and outlet assembly 1 is sprayed more evenly under the action of the staggered airflow, thereby solving the defect of uneven material spraying of the device.

[0029] A plurality of separation plates 6 are fixed to the inner surface of the air intake pipe 3 .

[0030] The device is provided with a separation plate 6, which is used to separate the gas entering the blowing plate 2, so that the gas is discharged more evenly from the gas outlet 7, so that the gas is distributed more evenly in the V-shaped channel 5, so that the material is sprayed more evenly.

[0039] In addition, by providing the square basin 13, the square basin 13 is used to remove the material impurities entering the nozzle plate 8, so that the nozzle plate 8 is not easily blocked by the impurities.

[0040] Working principle: the material enters the square basin 13 through the threaded barrel 18 for filtration, the filtered material enters the discharge hole of the nozzle plate 8 through the connecting frame 10, and finally enters the V-shaped channel 5, and then the gas enters the V-shaped channel 5 through the air inlet pipe 3, and the gas blows the material discharged by the inlet and outlet assembly 1. Since the shape of the V-shaped channel 5 is V-shaped, the material discharged by the inlet and outlet assembly 1 is sprayed more evenly under the action of the staggered airflow.
