Circular PU air filter element production method

Abstract

The invention relates to a circular PU air filter element production method including the following steps that firstly, upper molds are put onto a mold conveying assembly line to be heated and then flow into an upper mold glue injection area to be subjected to glue injection, the upper molds completely subjected to glue injection flow into an upper mold paper insertion area to be subjected to manual paper insertion, and then upper end cover formed filter element semi-finished products are obtained after the upper molds pass an upper mold foaming solidifying heat preservation and height limitation area; secondly, the upper molds are continuously put onto the mold conveying assembly line, and the first step is unceasingly repeated; thirdly, lower end covers are formed at the other ends of the semi-finished products, and the forming process is basically the same as that in the first step; and fourthly, after curing and demolding, finished product circular PU air filter elements are obtained. According to the circular PU air filter element production method, the circular PU air filter elements are produced through a continuous production method, assembly line production is adopted forkey working procedure points, including glue injection, foaming solidifying heat preservation and height limitation, curing heat preservation and pre-demolding, in PU air filter element production, the production efficiency can be improved, the labor intensity can be lowered, raw material waste can be reduced, and quality stability can be improved.

Description

technical field [0001] The invention relates to a production method of a filter element, in particular to a production method of a circular PU air filter element. Background technique [0002] At present, the production process of large circular PU air filter products (more than 200mm in diameter and more than 350mm in height) of most domestic air filter manufacturers is not highly automated, and most of the processes are in a manual state, that is, each process is carried out separately. , continuous production cannot be realized, the existing intermittent production method has low production efficiency, high labor intensity of workers, poor quality control, long preparation time before production, and relatively large waste of materials. Big and other deficiencies.

Problems solved by technology

[0002] At present, the production process of large circular PU air filter products (more than 200mm in diameter and more than 350mm in height) of most domestic air filter manufacturers is not highly automated, and most of the processes are in a manual state, that is, each process is carried out separately. , continuous production cannot be realized, the existing intermittent production method has low production efficiency, high labor intensity of workers, poor quality control, long preparation time before production, and relatively large waste of materials. Big and other deficiencies

[0003] The filter production lines of some foreign-funded enterprises use professional robots for production, which can solve some shortcomings such as low production efficiency and high labor intensity of workers. However, the production line structure adopted by them is only suitable for large-scale single-variety production, and mold replacement is inconvenient. It is not conducive to the production of small batches and multi-variety products, and the cost is high, which ordinary small and medium-sized enterprises cannot afford
