A kind of production method of circular PU air filter element

Abstract

The invention relates to a production method of a circular PU air filter element, comprising the following steps: (1) put the upper mold on the mold conveying line for heating, then flow into the upper mold glue injection area for glue injection, and the upper mold after the glue injection is completed Flow into the upper mold paper insertion area for manual paper insertion, and then pass through the upper mold foaming and curing heat preservation height limit area to obtain the upper end cover forming filter element semi-finished product; (2) The upper mold is continuously put on the mold conveying line, and the step (1) is repeated continuously ; (3) Forming the lower end cover on the other end of the semi-finished product, the forming process is basically the same as step (1); (4) Finally, after aging and demoulding, the finished circular PU air filter element is obtained. The invention adopts a continuous production method to prepare circular PU air filter elements, and the key process points in the production of PU air filter elements: glue injection, foaming and curing heat preservation and height limit, aging heat preservation, and pre-demolding are produced by assembly lines, which can improve production. Efficiency, reduce labor intensity, reduce raw material waste, and improve quality stability.

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. [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 wo...

[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
