AI Technical Summary

Technical Problem

In existing technologies, the composite geomembrane is prone to adhesion between the edges of the geomembrane and geotextile during the lateral edge-throwing process, resulting in uneven edge-throwing, which affects processing efficiency and makes it difficult to achieve stable compaction and centered transport through mechanical structures.

Method used

The system employs a combination structure of a threaded rod, a first clamping plate, and a limiting rod. The rotation of the threaded rod drives the threaded movement of the first clamping plate, which slides in conjunction with the support frame to maintain the centered position of the moving base plate. At the same time, auxiliary rollers and composite rollers clamp the geomembrane and geotextile to achieve stable conveying. The bidirectional screw and the second clamping plate engage with each other by rotating the handle, maintaining the centered position of the geomembrane during the unwinding process.

Benefits of technology

It achieves precise bonding of composite geomembrane and geotextile, avoids deviation, improves processing efficiency and stability, and ensures uniform edge casting and centered delivery of geomembrane and geotextile.

Abstract

The utility model discloses a kind of lateral edge throwing devices of composite geomembrane, including support frame, the inside rotation of support frame is connected with conveyor belt, the upper side of support frame is uniformly connected with side plate, the inside rotation of side plate is connected with several auxiliary rollers, the outside of auxiliary roller is wound with geomembrane, one end of geomembrane is wound with unwinding roller, the other end of geomembrane is wound with composite roller, the unwinding roller and composite roller are all and side plate rotation cooperation, the upper conveying of conveyor belt is with moving base plate, the upper of moving base plate is provided with geotextile, geotextile and geomembrane press-fit cooperation. By handle rotation, drive bidirectional screw rotation after rotation, then with screw block carries out thread cooperation, second clamping plate can be close to middle part, can keep geomembrane unwinding process also keep central position, not prone to deviation, then geotextile and geomembrane can be compounded together.
