Embodiment Construction

[0009] In Figure 1, mix the epoxy resin and curing agent evenly to make the epoxy resin into a liquid state, pour the liquid epoxy resin into the mold 4 in turn, and after a few minutes, insert the central tube 3 and the filter paper tube 2 into the liquid state In the epoxy resin, the epoxy resin is cured naturally to form the upper and lower end caps 1, 1' of the epoxy resin. The element is pulled out of mold 4, which replaces the end cap, adhesive and end cap seal with epoxy. In addition, an accessory O-ring is included in the accessory bag, so that the sealing ring on the assembly can be replaced when the filter element is replaced.

Abstract

The invention discloses a filter cleaner filter core, including upper and lower cover(1, 1 '), filter paper web(2), the center tube(3), in filter paper web(2) Set in the out of center tube(3), characterized the described upper and lower cover(1,1 ') used epoxy material production, epoxy curing period after solidifying with center tube(3) and filter paper web(2) at the same time connected to the two ends of one. Instead of using epoxy Cover, binder, Seal, it has a simple structure, reduce weight, no longer need punch, bonding, curing and heating, as long as the resin into the mold, let it filter paper web and the center tube integration can be cured with natural, it significantly reduced processes and equipment, based on the same size filter specifications and performance, simplified streamline processing and product mix, reducing the weight of the product, without unglued phenomenon, reduced processing equipment.

Description

【Technical field】 [0001] The invention relates to a filter core for filtering impurities in engine oil or fuel oil, which can improve the corrosion resistance and service life of the filter core and greatly reduce the weight of the filter. 【Background technique】 [0002] At present, the known filter elements are composed of upper and lower covers, adhesives, filter paper tubes, center tubes and other parts, while our traditional filter elements are made of iron end caps, filter paper tubes and center tubes with adhesives. Then insert a sealing ring in the inner hole of the end cover. The filter element needs to go through processes such as glue injection, bonding, heating and curing, and the end cover needs to be stamped. The bonding strength of the binder is not good, and there is often degumming; the original iron end cover and the binder make the overall weight of the filter element appear heavy. However, OEMs require to develop in a lightweight direction in order to sav...
