Problems solved by technology

In the actual use process, there are several obvious deficiencies in the process from unwinding to cloth storage, and from cloth storage to dipping in the dipping tank. First, the geogrid will shrink in the weft direction, resulting in square grids. The second is uneven gluing and inconsistent temperature in the drying room, which makes the tenter effect poor, and it is easy to cause uneven stress on the mesh cloth, resulting in local breakage, etc.

Embodiment Construction

[0010] The present invention will be described in detail below in conjunction with accompanying drawing:

[0011] figure 1 Shown is the process flow diagram of the prior art, which includes unwinding 1, cloth storage 2, rubber dipping 3, pressing roller extrusion 4, tenter drying 5, cloth output cooling traction 6, cloth storage 7, roll Take 8.

[0012] figure 2 Shown is a process flow diagram of the present invention, which includes: unwinding 11, weft trimming 12, cloth storage 13, constant tension traction 14, dipping 15, tenter drying 16, constant tension cloth cooling traction 17, Cloth storage 18, coiling 19 again. In the present invention, after unwinding 11, the geogrid is seamed by a sewing machine first, and then enters the weft adjustment device, and the geogrid is straightened in the weft direction to realize its seaming and weft adjustment process; the geotextile weft After straightening, it enters the cloth storage machine for cloth storage 13, where the clo...

Abstract

The invention relates gumming stretching shaped method, comprising the following steps: accumulating, gumming, stretching and drying, discharging cloth, cooling, towing, accumulating and winding; putting the grid into impregnating groove; before accumulating, carrying out hemming and straightening weft; after accumulating, setting the draught device which is composed at least a drawoff roller, and after stretching and drying, setting cloth discharge and cooling draught device to cool and draw the grid. The method is simple and the grid is not out of shape.

Description

technical field [0001] The invention relates to a tenter setting method for geotechnical drape, in particular to a tenter set method for geotechnical grid cloth. Background technique [0002] Geotextiles are one of the textile products, mainly used in geotechnical engineering where soil, rock and water are connected, or used as walls, roads, window screens, etc., and are widely used in water conservancy, transportation, building materials and other fields as a a reinforcing material. As a kind of geotextile, geogrid also has a wide range of applications. At present, the pre-processed geogrid must go through a process such as dipping and tentering, the purpose of which is to ensure the smoothness of the fabric and the squareness of the grid. Generally, the rubber dipping and tentering shaping process consists of the following steps: unwinding, cloth storage, rubber dipping, pressing roller extrusion, tenter drying, cloth cooling and traction, cloth storage and coiling. In ...
