Punctiform needle-punching equipment and processing technique

Abstract

The invention discloses punctiform needle-punching equipment. The punctiform needle-punching equipment comprises a conveying component, a supporting net mechanism, a punctiform needle-punching mechanism and a control unit, the conveying component is used for conveying fiber web to a needle-punching area, the supporting net mechanism is used for supporting the fiber web in the needle-supporting area, the punctiform needle-punching mechanism comprises a needle bed component and a needle bed traverse component, the needle bed component is used for conducting needle-punching on the fiber web, the needle bed traverse component is used for making the needle bed component move in the direction vertical to the conveying direction of the fiber web, and the needle bed component is provided with pin headers which are arrayed at equal intervals in the conveying direction of the fiber web; the control unit is used for controlling the movements of the conveying component, the needle bed component and the needle bed traverse component matched, and thus the punctiform needle-punching of the fiber web is achieved. According to the punctiform needle-punching equipment and the processing equipment, by controlling the conveying component, the needle traverse component and the needle bed component to be matched with one another, the pricking needle on the needle bed component merely conducts repeated needle punching on the partial point location of the fiber web, the purpose of forming the least destroying on the fiber web is achieved, and the fiber web has enough peel strength at the same time.

Description

technical field [0001] The invention relates to the field of ecological non-woven composites, in particular to a point-shaped acupuncture equipment and a processing technology. Background technique [0002] The riparian zone is a semi-terrestrial ecosystem between the river and the land. It is directly or indirectly affected by the change of the river water level and has a buffer effect. It usually connects the above-ground terrestrial system and the terrestrial system through the hydrological process of surface runoff and subsurface flow. aquatic system. The area ratio of the riparian zone is not high in the watershed ecosystem, but it plays an irreplaceable role in the process of water and nutrients flowing into the river. It intercepts non-point source pollution, builds river habitats, and promotes the connectivity between the river and its surrounding environment. have important meaning. In recent years, scholars at home and abroad have begun to use ecological engineer...

Problems solved by technology

However, needle punching also has disadvantages in the implementation process: needle punching has certain damage to the strength and structure of the composite fabric; the peel strength between the composite fabrics is small; most of the fibers passing through the composite in the non-woven composite fabric are in the The semi-free state is easy to be pulled off under the action of external force (such as repeated washing by water flow), and eventually lead to the failure of its overall function
