A kind of dust arrester of printing machine
Technical field
The utility model relates to printing manufacturing technology field, is specifically related to a kind of dust arrester of printing machine.
Background technology
Printing machine is a kind of instrument word and pattern be coated in by the printing slurries such as ink by forme on the stocks such as paper.Fold when printing on the stock such as paper, the dust impurity etc. of adsorption all can have an impact to the printing quality of final products.So, usually need before printing to carry out dust removal process to the paper of printing.
Existing one printing dedusting mechanism, publication number is: CN102009523A, by arranging dust removal piece between the transfer platform and printing stencil of the placement of printing machine product to be printed, when transferring platform and driving below product to be printed to printing stencil, transfer platform and product to be printed are through dust removal piece, magazine on product to be printed is removed by dust removal piece, thus makes product to be printed cleaned before printing.But, dedusting roller on this dedusting mechanism and stickup roller rotate attract dust repeatedly, and dust above can not drop in time, can again adsorb back dedusting roller, dust on dedusting roller causes secondary pollution to paper again, the dust on paper can not be removed thoroughly.In addition, the paper after dancing roll dedusting, produces electrostatic because of friction, affects follow-up printing process quality.
Utility model content
The purpose of this utility model solves the problem, there is provided a kind of mechanism reasonable, the dust arrester of good dedusting effect, with solve dancing roll work long hours after the dust of accumulation because of friction, the problems such as electrostatic are produced to the paper after paper causes secondary pollution and dancing roll dedusting.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of dust arrester of printing machine, comprise setting printing table on the printer and gate framework, described gate framework is arranged at above printing table, the described printing table left and right sides is equipped with column, described column is provided with sliding shoe, cylinder one is provided with above described sliding shoe, between described two sliding shoes, dancing roll is installed, dust cleaning case is provided with above dancing roll, described dust cleaning case is provided with dust suction air port, upper end, dust suction air port is provided with a filter screen, filter screen side is provided with dust scraping plate, dust scraping plate connects cylinder two, air exhauster and dust-exhausting port is also provided with in described dust cleaning case, described dust-exhausting port connects a dust bag, and dust bag is arranged on gate framework side.
Concrete, be also provided with in described gate framework and destatic mechanism.
As preferably, the material of described filter screen is polyester fiber.
As preferentially, described dust bag outside is also provided with one deck sealing bagging.
The utility model beneficial effect is: first, the utility model by the rotation of dancing roll by the dust adsorption on paper on dancing roll, again by the air exhauster of dust cleaning case by dust adsorption in this casing, then cylinder push-and-pull action is utilized to drive dust scraping plate to promote to dust-exhausting port, dust is sent in dust bag, improve dust removing effects; Next destatics mechanism effectively can eliminate the electrostatic that paper produces in dust removal process; The last one deck that is provided with in dust bag outside seals bagging, is conducive to avoiding less dust to get out from the space of dust bag, pollutes workshop condition and printing finished product.

Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings 1, the technical solution of the utility model is described in further detail.
Be the dust arrester of a kind of printing machine described in the utility model as shown in Figure 1, comprise and be arranged on printing table 2 on printing machine 1 and gate framework 3, gate framework 3 is arranged at above printing table 2, printing table 2 left and right sides is equipped with column 4, column 4 is provided with sliding shoe 5, cylinder 1 is provided with above sliding shoe 5, between two sliding shoes 5, dancing roll 7 is installed, dust cleaning case 8 is provided with above dancing roll 7, dust cleaning case 8 is provided with dust suction air port 9, upper end, dust suction air port 9 is provided with a filter screen 10, filter screen 10 side is provided with dust scraping plate 11, dust scraping plate 11 connects cylinder 2 12, air exhauster 13 and dust-exhausting port 14 is also provided with in dust cleaning case 8, dust-exhausting port 14 connects a dust bag 15, and dust bag 15 is arranged on gate framework side.Also be provided with in gate framework 3 and destatic mechanism 17.The material of filter screen 10 is polyester fiber.Dust bag 15 outside is also provided with one deck sealing bagging 16.
The operation principle of the present embodiment is: first regulate the distance between printing table 2 and dancing roll 7 by cylinder 1, then will treat that the paper of dedusting carries out dedusting and paper stretching through dancing roll 7, destaticing mechanism 17 can prevent the paper of printing table from producing electrostatic because of friction, when dancing roll 7 runs work, the dust cleaning case 8 of top passes through air exhauster 13 by the dust adsorption on dancing roll 7 in this casing, then cylinder 2 12 push-and-pull action is utilized to drive dust scraping plate 11 to promote to dust-exhausting port 14, dust is sent in dust bag 15, improve dust removing effects, dust bag 15 outside is provided with one deck sealing bagging 16, be conducive to avoiding less dust to get out from the space of dust bag, pollute workshop condition and printing finished product.
The present embodiment is the embodiment of the utility model example; technical conceive of the present utility model and feature; its object is to person skilled in the art scholar understand content of the present utility model and implemented; can not limit protection domain of the present utility model with this, all equivalences done according to the utility model Spirit Essence change or modification all should be included in protection domain of the present utility model.
