Method for manufacturing non-woven fabric composite brown paper end cover filter element assembly and product

Abstract

The invention discloses a method for manufacturing a non-woven fabric composite brown paper end cover filter element assembly. The method comprises the following steps: firstly, folding, beating and clamping filter paper to obtain a filter paper assembly filled with a central tube, and meanwhile, manufacturing a composite double-layer material of non-woven fabric and brown paper; secondly, ultrasonically welding the composite double-layer material, serving as upper and lower end covers, to two end parts of the filter paper assembly to finally prepare a finished non-woven fabric composite brown paper end cover filter element assembly product, wherein the brown paper is positioned on the outer layer and faces outwards, and the non-woven fabric is positioned on the inner layer and faces inwards. According to the non-woven fabric composite brown paper end cover filter element assembly, the end covers are made of the double-layer material of the non-woven fabric and the brown paper, the brown paper is positioned on the outer layer, and the non-woven fabric is positioned on the inner layer. Original metal end covers are replaced with non-woven fabric composite brown paper end covers, and only the ultrasonic welding process is needed, so that production procedures are greatly reduced, steel and labor are saved, the labor rate is improved, the defective rate is reduced, and the environment protection and energy saving properties are good.

Description

technical field [0001] The invention relates to a vehicle filter, in particular to a manufacturing method and a product thereof for a filter element assembly applied to the filter. Background technique [0002] At present, the filter element assembly of the existing vehicle filter is composed of folded filter paper, a central tube, an upper end cover and a lower end cover. The upper and lower end caps are made of metal. The manufacturing method is: first put the flat filter paper on the large slitting machine for large slitting, then send it to the small slitter for small slitting, and pass through the oven, and separate it with a small slitting knife to form folded filter paper of required specifications (this is called the folding process); then put the folded filter paper into the conveyor belt for automatic clamping, then put the center tube into the center of the folded filter paper and tie it with a rubber band (this is called the clamping process); then put the upper...

AI Technical Summary

Problems solved by technology

The manufacturing method of the filter element assembly of the metal end cap is relatively complicated and cumbersome, and the materials of the upper and lower end caps are all metal (the iron end cap needs to be stamped and formed), and a large amount of water will be consumed in the production process due to its material. and electric energy, and a large amount of steel is wasted, and the overall filter element assembly is bulky, and it is not easy to degrade in the environment after being discarded, causing pressure on the environment and increasing the degree of pollution

The filter element assembly is generally a one-time consumable, which requires a relatively high cost and does not meet the requirements of energy conservation and environmental protection.
