Vacuum cooling equipment used in the production of meltblown materials

Abstract

The invention discloses a vacuum cooling device applied to the production of melt-blown materials, which belongs to the technical field of non-woven special materials production. It includes a motor. Linkage spindles, the linkage spindles can realize on-off, the first roller and the linkage spindle are equipped with the first roller, the first roller and the second roller are connected by a belt, and one end of the rotating shaft on the second roller is connected with a rotating rod , the other end of the rotating rod is hinged with a first connecting rod, the other end of the first connecting rod is hinged with a second connecting rod, the second connecting rod is hinged with a piston rod, the front end of the air pump is connected to the air duct, and the other end of the air duct extends into the In the cooling channel of the cooling box. The device divides the cooling box to form multiple cooling channels, and each channel adopts a partition-controlled vacuum device to cooperate with a cooling device for cooling operation, which greatly improves the efficiency of cooling and forming, and then promotes the improvement of production efficiency.

Description

technical field [0001] The invention relates to the technical field of production of special materials for non-woven fabrics, in particular to vacuum cooling equipment applied to the production of melt-blown materials. Background technique [0002] The production process of melt-blown nonwovens (melt-blown non-woven fabrics) is a civil industrial technology developed by Exxon Mobil in the United States in the 1960s on the basis of the air-jet spinning method researched by the US Navy Laboratory, and then melted The patent license for the production of jet nonwoven technology is granted to several companies. Melt-blown non-woven materials are widely used in medical protection, sanitary cleaning materials, filter materials, thermal wadding materials, oil-absorbing materials, battery separators and other fields because of their excellent barrier filtration, air permeability, oil absorption, thermal insulation and sound insulation properties, and It has heat and oxygen aging re...

Problems solved by technology

With the unremitting efforts of independent research and development and innovation, the quality of domestic materials is gradually improving and has been more and more recognized by the market. The domestic excellent production technology is also being continuously optimized and improved. For example, the Chinese patent No. CN201510023201.8 has been published A production method and production equipment for polypropylene melt-blown non-woven special materials, which solve the problem of unstable melt index and wide molecular weight distribution in the production process of the existing technology, which is not suitable for the melt-blown spinning process; and the die head and water tank Inappropriate design, difficult molding and other problems, the non-woven fabric produced by the above process is soft to the touch, has good air permeability, excellent filterability, and no peculiar smell, and has been recognized by downstream customers

However, there is no perfect production process and equipment. In the process of use, we found that with the increase of market demand, the production efficiency of the existing technology still needs to be improved. It also causes a large consumption of water resources, and at the same time, it is necessary to add air-drying equipment for air-drying, which further increases the cost and energy consumption
