Agricultural plant fiber film production equipment

Abstract

The invention discloses agricultural plant fiber film production equipment. The agricultural plant fiber film production equipment comprises a long fiber web forming assembly, a short fiber web forming assembly, an impregnator and a drying consolidation device, and is characterized in that the long fiber web forming assembly is used for preparing a long fiber web in a traction lapping mode after along fiber raw material is opened; the short fiber web forming assembly is used for preparing a short fiber web in an airflow web forming mode after the short fiber raw material is opened, and conveying the short fiber web to the long fiber web, so that the short fiber web and the long fiber web are overlapped to form a double-layer composite fiber web; the impregnator is used for performing saturated impregnation on the double-layer composite fiber web; and the drying and consolidation device is used for drying and consolidating the double-layer composite fiber web subjected to saturated impregnation. According to the production equipment, the short fiber raw material and the long fiber raw material can be used for producing the double-layer composite fiber web, the double-layer composite fiber web is higher in strength, the difficulty of passing through the impregnator is small, the conveying speed of the double-layer composite fiber web does not need to be reduced, the production efficiency can be improved, and the yield of agricultural plant fiber film products is also increased.

Description

technical field [0001] The invention relates to the technical field of machinery industry, more specifically, relates to a production equipment of agricultural plant fiber membrane. Background technique [0002] The "white pollution" caused by the long-term use of plastic mulch has ravaged the earth and brought great harm to agricultural production and the environment. Therefore, the current research direction is mainly on degradable mulch, such as agricultural plant fiber film, and the existing agricultural plant fiber film. The production equipment has high requirements for plant fiber raw materials. It can only produce plant fibers with a length of more than 1cm and a fiber content of not less than 50%, and the longest length does not exceed 5cm. As a result, the strength of the fiber web paved with raw materials is low, and it is difficult to pass through the impregnation machine. It is necessary to control the transmission speed of the fiber web, which seriously affects...

[0002] The "white pollution" caused by the long-term use of plastic mulch has ravaged the earth and brought great harm to agricultural production and the environment. Therefore, the current research direction is mainly on degradable mulch, such as agricultural plant fiber film, and the existing agricultural plant fiber film. The production equipment has high requirements for plant fiber raw materials. It can only produce plant fibers with a length of more than 1cm and a fiber content of not less than 50%, and the longest length does not exceed 5cm. As a result, the strength of the fiber web paved with raw materials is low, and it is difficult to pass through the impregnation machine. It is necessary to control the transmission speed of the fiber web, which seriously affects the production efficiency and the yield of the product

[0003] In addition, because the raw materials used in agricultural plant fiber membranes are relatively poor raw materials and various leftovers, the quality of each batch of fiber raw materials is different, so the product performance and quality are unstable.
