[0002] In the production of pre-wetted cleanroom wipes, the pre-wetting device is a crucial step. Its main function is to moisten the cleanroom wipes to facilitate subsequent processing. Currently, there are two main types of pre-wetting equipment: spray type and immersion type. Immersion type is generally suitable for products requiring higher humidity but uses more liquid and also results in liquid waste. Therefore, spray type is currently the most common pre-wetting method.

[0003] However, the spray pipes of existing spray-type pre-wetting devices are fixed. When wetting the surface of the cleanroom cloth, the fixed position of the spray pipes can easily lead to missed spraying or uneven spraying, resulting in insufficient wetting in some areas and affecting the consistency and quality of the product.

[0022] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model and are not used to limit the scope of the utility model. ​

[0023] In the production process of pre-wetted dust-free cloth, the pre-wetting device is an important process, which mainly functions to wet the dust-free cloth for subsequent processing. At present, the pre-wetting device mainly has two types: spraying type and soaking type, and the soaking type is usually suitable for products requiring higher humidity and uses more liquid, which also causes liquid waste. Therefore, the current pre-wetting method mainly uses spraying.

[0024] However, the spraying pipe of the existing spraying type pre-wetting device is fixed, and when wetting the surface of the dust-free cloth, due to the fixed position of the spraying pipe, the phenomenon of missed spraying or uneven spraying easily occurs, which leads to insufficient wetting in some areas, affecting the consistency and quality of the product.
