[0002] In the technical field of latex production, the application range of latex products is increasingly wide, covering many products such as mattresses, pillows and gloves, and the market demand for the yield and quality of the latex products is also rising. By scattering talcum powder on the surface of the latex pad, the problem of adhesion of the latex in the subsequent processing process can be effectively prevented, the appearance of the product is more flat and smooth, and the performance is more stable, so that the competitiveness of the product in the market is improved, and the demand of consumers for high-quality latex products is met.

[0003] A common powder scattering device comprises a conveying frame, and a powder scattering device is arranged on the conveying frame. The powder scattering device is composed of a storage box and a fixed support, and the bottom of the storage box is provided with a gauze screen. Two guide rails are arranged on the fixed support, and the storage box can move back and forth through the cooperation of the rollers and the guide rails. By using this structure, the storage box moves back and forth, and the talcum powder on the gauze screen falls to realize powder scattering.

[0004] However, in actual operation, the talcum powder may be agglomerated, which may cause the gauze screen to be blocked, thereby affecting the powder scattering effect. SUMMARY
