Paving seam prefabricated body base cloth separating device

Abstract

The invention discloses a paving seam prefabricated body base cloth separating device. The device comprises a driving roller, pressing wheels and an exhaust cylinder, which are fixed by a rack througha shaft. The pressing wheels are fixed on the front end of a clamping arm through a shaft, and the wheel edge is tightly attached to the top of the driving roller. The rear end of the clamping arm isfixed with the rack through a shaft. The exhaust cylinder is arranged on the front side of the driving roller in parallel, and an exhaust groove is formed in the cylinder wall. A hot air gun provideshot air from the end of the exhaust cylinder. The driving roller is driven by a motor shaft and is in linkage with base cloth cooperatively pressed by the driving roller and the pressing wheels. Theexhaust groove is used for heating the bottom face of the base cloth. Base cloth is guided to move directionally through pressing force between the pressing wheels and the driving roller. A paving seam prefabricated body is guided to be separated from the base cloth through a separation roller. Hot air is guided out directionally through the exhaust cylinder to heat hot melt yarn, and the paving seam prefabricated body and the base cloth are unlocked. By means of the multiple sets of pressing wheels, separation operation of multiple pieces of paving seam prefabricated body base cloth can be achieved at the same time. The heating temperature and time of paving seam prefabricated body hot melting yarn can be controlled through the hot air gun. High racticability and wide applicability are achieved.

Description

technical field [0001] The invention relates to a base cloth separation device, in particular to a base cloth separation device for a seam-laying prefabricated body, and belongs to the technical field of composite material separation. Background technique [0002] In the field of composite materials, the prefabricated body prepared by fiber variable angle traction and joint laying technology can make full use of the excellent mechanical properties of fibers. The fiber tow is stitched on the fabric base cloth by using hot-melt yarn to make the seam-laying preform, and the fabric base cloth needs to be removed before the seam-laying preform is formed into a composite material part. [0003] At this stage, the removal of the base fabric is usually carried out by hand-held heat guns to heat the hot-melt yarn and separate the base fabric. There are problems such as low work efficiency, long heating time of the hot-melt yarn, unstable control of the heating temperature, and unstab...
