Embodiment 1

[0012] Embodiment 1: with reference to attached figure 1 . A reinforced rib filter screen, the film surface of the polymer resin film 1 constituting the reinforced rib filter screen is composed of a plurality of rectangular holes 2, the intersection point between the rectangular holes and the rectangular holes is the convex rib forming point 3, and the convex rib forming point 3 and Between the convex rib forming points 3 are mesh bars 4 and form an integral structure with the convex rib forming points 3 . The polymer resin film 1 is made of polyester film, nylon film, polypropylene film, polyethylene film or polyvinyl chloride film.

Embodiment 2

[0013] Embodiment 2: with reference to attached figure 2 . A forming die roll for a reinforced rib filter net, the roll surface of the forming die roll 5 is a concave-convex surface structure and the distribution structure of the concave-convex surface is four concave molds 5-1, an intermediate convex mold 5-2, or four convex molds 5 -2 intermediate system die 5-1. The punch 5-2 is a rectangular punch.

Embodiment 3

[0014] Embodiment 3: with reference to attached image 3 . A method for forming a reinforced rib filter net, in which polymer resins are respectively melted through a casting machine 6 and cast polymer plastic films are entered between the roll surfaces formed by forming die rolls 5 and extrusion rolls 7, and the forming die rolls The concave die 5-1 in the surface squeezes the film surface of the polymer plastic film into a raised part, and the punch 5-2 penetrates the film surface of the polymer plastic film to form a rectangular hole. The involute chain located in the oven The clips in the transmission mechanism 10 clamp the two sides of the polymer resin film and under the synchronous drive of the involute chain transmission mechanism, while pulling the polymer resin film to move forward, gradually the rectangular hole of the polymer plastic film Transverse stretching and longitudinal stretching force the polymer resin film between the pits and the pits in the polymer tre...

Abstract

The invention relates to a reinforced bar filtration mesh made of macromolecule resin and a preparation method thereof, the film surface of the macromolecule resin film which constructs the reinforcedbar filtration mesh consists of a plurality of rectangular orifices, the crosspoints among the rectangular orifices are convex bar forming points, among the convex bar forming points are the mesh bars which are in monolithic construction with the convex bar forming points. The invention has the advantages that: 1. as the joint points of longitude lines and the latitude lines which construct the mesh are the convex bar points which can not cause the position of the orifices to displace and have high strength; and 2. the joint points of longitude lines and the latitude lines which construct themesh are the convex bar points which are shaped and blended together by a die roller directly, thus having good shaping property and high strength of the mesh bars.

Description

technical field [0001] The present invention relates to a reinforced rib filter net made of polymer resin and its preparation method, which is mainly used for air filtration, liquid filtration, prevention of birds, insects, wind, and reinforcement of non-woven fabrics and other materials, belonging to filter nets manufacturing field. Background technique [0002] CN1727031A, name "a method for making a punching three-dimensional filter screen", punching a large piece of material into uniformly distributed holes with a screen punching machine; then stretching the punched material into a honeycomb shape Material; then bonded layer by layer with adhesive to form a three-dimensional filter. Its shortcoming: because there is no reinforcing rib point formed between the meshes of the formed filter screen, the filter screen itself has low filtering strength, is easily damaged, and lacks practicability. Contents of the invention [0003] Design purpose: to avoid the deficiencies ...
