Abstract

The invention discloses a plastic protection drainage plate non-woven fabric compound device. The device comprises a conveying mechanism for conveying a drainage plate, a non-woven fabric unwinding machine, a cylinder heater and a track type mold. The track type mold comprises a pair of annular chains arranged in parallel. The two ends of the annular chains are meshed with first chain wheels and second chain wheels for tensioning the annular chains, and transmission shafts are connected between the two first chain wheels and the second chain wheels respectively; chain plates of the annular chains are each provided with a connecting plate, transverse plates are connected between the two connecting plates corresponding to the two annular chains, the transverse plates and the drainage plate are arranged in parallel, and the interval between any two transverse plates is equal to the longitudinal distance between bosses on the drainage plate, a plurality of mold nails are arranged on the transverse plates, and the mold nails correspond to the bosses one to one. The technology is reasonable, and the problems that defects are caused when the non-woven fabric is loosened and sunken after the drainage plate is tiled, the whole deformation is caused by baking and the strength is lowered are solved.

Description

technical field [0001] The invention relates to the technical field of production of plastic drainage boards, in particular to a non-woven composite process and equipment for plastic protective drainage boards. Background technique [0002] The plastic protective drainage board is made of high-density polyethylene (HDPE) or polypropylene raw material through hot-melt extrusion and vacuum suction to form a concave-convex film. The plastic protective drainage board includes a base plate and a boss set on the base plate. The base plate is continuous and convex. The platform has a three-dimensional space and a certain supporting height. The top of the boss is covered with a geotextile filter layer, which is used for waterproof, hydrophobic, drainage and water storage products. It is mainly used for waterproofing and drainage in areas such as garage roof greening, roof greening, subways, tunnels, underground pipe galleries, and landfills. [0003] In the structure of the entire...
