Abstract

The utility model discloses a web printing on-line dust-collection device, comprising a guide roller for transporting a printing stock and a dust pipe, wherein an air suction groove is arranged on the surface of the dust pipe contacted with the operation path of the printing stock and a wedge angle a capable of scraping is formed between a groove mouth wall of the air suction groove and the operation path of the printing stock. Compared with the prior technology, the web printing on-line dust-collection device has features of good dust-collection effect, durable device and saved cost.

Description

The online dust arrester of web printing

Technical field

The utility model relates to the printing machinery auxiliary device, especially a kind ofly can know paper ash, paper dirt and paper scrap, improves the online dust arrester of web printing of stock printability.

Background technology

The stock paper is at paper ash, paper dirt, the paper scrap produced and the cutting process generation is a large amount of, and in various body paper, coarse body paper, the health body paper of non-Tu cloth are even more serious, and these paper ashes, paper dirt, paper scrap have a strong impact on printing quality at printing process; Along with printing time increases, paper ash, paper dirt, the paper scrap of being brought into stamping ink pad by body paper increase, and have directly changed fineness, the viscosity of printing ink, influence the normal ink transfer of reticulate pattern China ink, cause and see net, printing quality problems such as site plucking; Printing paper scrap later also can come off, and causes small particles on printed patterns, and paper scrap also can overstock at felt wrapped roll, directly destroys the fineness on calendering oil surface, thereby paper ash, paper dirt, the paper scrap removed on the body paper are last important process of printing.

For this reason, people have developed some online dust arresters, open-type dust arrester as shown in Figure 1: it includes the deflector roll 2 that transports stock and is contained in two sweep-up pipes 5 of stock operating path 1 front and back respectively, sweep-up pipe 5 is provided with the brush board 4 that hairbrush 3 is housed, the inlet scoop 6 of sweep-up pipe is towards stock operating path 1 and leave a segment distance, brush paper ash, paper dirt and paper scrap for hairbrush and fall, the inlet scoop 6 through aspiration channel 5 sucks and is discharged by the negative pressure of vacuum system again.

This dust exhaust apparatus has following defective:

(1) hairbrush life-span weak point lost efficacy easily.

(2) hairbrush top is piled up a large amount of paper ash dirt, paper scrap easily, and amasss into lumps, and suction can't be removed, and causes more serious consequence on the contrary.

(3) inlet scoop directly communicates with atmosphere, influences negative-pressure sucking, and pick-up performance is poor.

The utility model content

The utility model provides a kind of web printing online dust arrester, and it can solve the easy problem of damaging of parts of prior art dust removing effects difference and dedusting machine.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: it includes deflector roll and the sweep-up pipe that transports stock, contacted of described sweep-up pipe and stock operating path are provided with the air draught groove, and the notched wall of described air draught groove and stock operating path form a locking angle that plays scraping action.

In the technique scheme, more particularly: the air draught groove on the described sweep-up pipe can have two, and described sweep-up pipe is connected with the transition airduct, and this transition airduct is connected with vavuum pump; Described sweep-up pipe has two, these sweep-up pipe two ends are by being bolted on mount pad and the fixed head, described fixed head two ends can be provided with deep-slotted chip breaker, described fixed head is connected with fixed bar by the bolt in this deep-slotted chip breaker, when unscrewing screw rod, fixed head is rotatable, and in order to adjust the angle of locking angle, the α angle can be 10 °～85 ° scope adjustment.

Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:

Because the air draught groove on the sweep-up pipe contacts with the stock operating path, when paper ran to the air draught notch, paper fully contacted and just seals notch with the air draught notch, had so just improved the negative pressure of sweep-up pipe, had strengthened the absorption affinity of sweep-up pipe; And notched wall and stock operating path form a locking angle, make notched wall play the effect of a scraping, can easily scrape paper ash, paper dirt, paper scrap on the paper, add the absorption affinity that sweep-up pipe is powerful, paper ash on the carrier, paper dirt, paper scrap are sucked fully by sweep-up pipe, pick-up performance is very good like this, and machine is not fragile, has saved cost.

The specific embodiment

Below in conjunction with the accompanying drawing example, the utility model is described in further detail:

The utility model as shown in Figures 2 and 3, it includes two deflector rolls 2 and sweep-up pipe 4-1 and the 4-2 that transports stock, contacted upper edge sweep-up pipe of sweep-up pipe 4-1 and stock operating path axially has two air draught groove 4-3, contacted upper edge sweep-up pipe of sweep-up pipe 4-2 and stock operating path axially offers two air draught groove 4-4, as shown in Figure 4, the notched wall of air draught groove and stock operating path form a locking angle that plays scraping action, when the width of stock during less than flute length, available transparent adhesive tape is partially enclosed growing, and prevents that negative pressure of vacuum system seal lost efficacy; The two ends of sweep-up pipe are fixed by bolts on mount pad 3 and the fixed head 5, fixed head 5 two ends are provided with deep-slotted chip breaker 5-1, and fixed head 5 is connected with fixed bar 6 by the bolt 10 in this deep-slotted chip breaker 5-1, when unscrewing screw rod, fixed head is rotatable, in order to adjust the angle of locking angle; Be connected with right wallboard 13 with the defeated paper of bolt 11 and printing machine left side wallboard 12 with fixed bar 6, transition airduct 8 is installed in the right wallboard of printing machine 13 outsides, transition airduct 8 is connected with sebific duct with dust catcher, and transition airduct 8 links to each other with vavuum pump 14, thereby forms a negative pressure of vacuum system.

Sweep-up pipe 4-1 inhales the front of stock, 4-2 inhales the reverse side of stock, and the paper ash dirt that scrapes off, paper scrap suck and discharge by the dust suction tube seat, because the length that can regulate sweep-up pipe air draught groove, make it to equate with the width of stock, stock is through sweep-up pipe the time, and the complete closed sweep-up pipe has improved the sweep-up pipe negative pressure, can also be according to the surface appearance of paper stock, change the angle of sweep-up pipe fixed head, can make locking angle, change scraping power 10 °～85 ° scope adjustment.

The hermetic type dedusting mechanism can be installed between the unwinding device and calendering device of web press, best results.
