Abstract
The invention relates to a production process for a flat PU (Poly Urethane) air filter, which is used for producing curing type filter paper. The production process comprises the following steps of: folding the filter paper and pouring glue; curing the filter paper; cutting off the filter paper; pouring PU glue; curing the PU glue; trimming the PU glue; and spraying a code. A frequency converter is arranged on a conveyor belt of an production line in a curing furnace; a coder is arranged in a folded filter paper line; the curing furnace receives signals sent from the coder, and the speed of the curing furnace is adjusted by the frequency converter in proportion on the basis of the calculation of the signals and is matched with the speed of the folded filter paper line, so that the step of curing the filter paper and other steps form the continuous production line. The heating function of the filter paper curing furnace can be shut down when the curing furnace is applied to the production of non-cured filter paper. According to the invention, the continuous production for the flat PU air filter is achieved, the space for the filter paper in a product storage area is saved, the investment for a container for storing the filter paper and a tray for storing the filter paper in the process of curing the filter paper is saved, and the hidden quality troubles such as breaking of the filter paper in circulation and moisture absorption and pollution of the filter paper in storage are avoided.
Description
Technical field
The present invention relates to the production technology and the equipment thereof of the dull and stereotyped air filtering core of a kind of PU, belong to the cleaner technical field.
Background technology
Automobile filter paper can be divided into the curing filter paper of water miscible non-curing filter paper and pure dissolubility according to solidification temperature.Curing type filter paper is used gel-type resin, and like the filter paper that phenolic resins, epoxy resin etc. are handled, non-curing type filter paper is to use thermoplastic resin, like the filter paper of polyacrylic, the processing of polyvinyl acetate class.
Curing type filter paper need use after curing, generally is used for air filter, fuel filter, oil strainer, heavy type or light-duty empty filter, its filter paper intensity and high life.Non-curing type filter paper does not solidify the use that can directly give a discount, and generally is used for the air filter.Prior art is produced and is used the processing step of the dull and stereotyped air filtering core that solidifies filter paper to be at present: folding filter paper heat injection melten gel → cut-out filter paper → curing filter paper → notes PU glue → PU curing → PU deburring → coding; Wherein, Because paper folding speed reached the stabilized speed process from zero after paper folding heat injection melten gel step was changed paper at every turn; Curing oven speed is non-adjustable; Therefore curing oven can't carry out synchronously with paper folding heat injection melten gel equipment; Therefore curing oven can't form continuous production line with paper folding heat injection melten gel equipment, and the existing technological process of production is that the filter paper curing oven is placed on a zone separately, is not linked to be continuous production line with other production equipments; If paper folding heat injection melten gel step is linked to be a continuous production line to solidifying the filter paper step, thereby cause paper folding speed and the curing oven speed filter paper of rolling well that do not match to be drawn back or push the problem that causes waste product easily.Simultaneously owing to consider that making production line can produce curing type filter paper filter core can produce non-curing type filter paper filter core again; So being used to solidify the curing oven of filter paper arranges all in independent zone not and the miscellaneous equipment line; This mode of production is when producing curing type filter paper air filtering core, and causing has in a large number at goods cutting off filter paper and solidify between the filter paper operation, increased the filter paper transhipment work between the two-step; Wasted many spaces, and production efficiency is reduced greatly.
Summary of the invention
The technical problem of the actual solution of the present invention is: to the production technology of curing type filter paper filter core; Because paper folding speed reached the stabilized speed process from zero after paper folding heat injection melten gel step was changed paper at every turn; Curing oven speed is non-adjustable; If paper folding heat injection melten gel step is linked to be a continuous production line to solidifying the filter paper step, cause paper folding speed and curing oven speed not to match easily, thereby the filter paper of rolling well is drawn back or push the problem that causes waste product.
The invention provides the production technology of the dull and stereotyped air filtering core of a kind of curing type filter paper PU, may further comprise the steps: step 1, roll over filter paper and inject filter paper sideline PUR and filter paper center line PUR; Step 2, curing filter paper; Step 3, cut-out filter paper; Step 4, notes PU glue; Step 5, PU adhesive curing; Step 6, PU deburring; Step 7, coding; Wherein, The said curing filter paper of step 2; Promptly; The filter paper entering temperature that injecting glue is accomplished is lower than the curing oven of said PUR fusing point, has installed on the streamline conveyer belt in the said curing oven in a frequency converter, the step 1 and on the folding filter paper line encoder has been installed, and the signal that curing oven described in the step 2 passes through to receive said encoder transmission is through calculating the speed of passing through frequency converter adjustment curing oven in proportion; Speed in order to folding filter paper line in the coupling step 1 makes step 1 form continuous streamline to step 7.
Said step 1 increases one or more groups fan above rolling paper well, having annotated the streamline of filter paper of glue, PUR was cooled off in the several seconds and solidify.
Said filter paper sideline glue and center line glue all adopt the elevated temperature heat melten gel of fusing point up to 170 ℃ to 190 ℃
