Description

Paper tape turn-over mechanism and printing production line

Technical field

The utility model is related to paper tape print field, more specifically, it relates to a kind of paper tape turn-over mechanism and printing life Producing line.

Background technology

At present, the press field packed in the cigarette of China, the printing to special cigarette paper, such as cigarette flexible package need to be to paper The band back side carries out preliminary treatment, the purpose is to effectively prevent cigarette wrapping paper band from deforming, influence aesthetics and packaging effect, common Processing method is to coat the methods such as special back coating liquid to realize at its back side.

To the back side process of this particular/special requirement soft pack of cigarettes, such as intaglio machine for web-fed printing tool without back up device, Usually need after being processed in paper mill, then printing is started by printing machine, or in existing intaglio machine for web-fed printing On the basis of, then add a back up unit to complete this operation.Common paper tape back side process method is present Defect：First, it is printed on the machine after being processed in paper mill, because region humiture is different, certain influence is caused on product quality；2nd, Increase a back up unit, expense adds cost input, have impact on economic benefit in ten thousand yuan of 40-50.

Therefore, the Chinese patent of Application No. 201320851901.2 discloses a kind of intaglio machine for web-fed printing paper tape and turned over Rotary device, it is by front wallboard, left wallboard, right wallboard, rear wall plate, the first dancing roll, the second dancing roll, the 3rd dancing roll, the 4th Dancing roll, the first twist rollers, the second twist rollers, the first air pump pipeline, the second air pump pipeline are constituted.Front wallboard both sides connect respectively Left wallboard, right wallboard are connect, the two ends of rear wall plate are connected with left wallboard, right wallboard, the second dancing roll, the 3rd dancing roll pass through branch Frame is fixed on front wallboard, and the 4th dancing roll is fixed on left wallboard by support, and the first dancing roll is fixed on the right side by support On wallboard, the first twist rollers, the two ends of the second twist rollers are separately fixed at the corner of four blocks of wallboards all around, the first air pump Pipeline, the second air pump pipeline are located at the first twist rollers, the lower end of the second twist rollers respectively.Operationally, conveying equipment starts defeated Tapes, pulls out mechanical back from paper tape of the first module by back side technical finesse first and faces outwardly, the paper of the back side outwardly Band enters the lower surface of the first twist rollers by the upper surface of the first dancing roll, and gas is from the first air pump pipeline, the second air pumping pipe Road enters, and holds up paper tape by its steam vent, paper tape is operated around the upper surface of the first twist rollers, into the second dancing roll upper end With the 3rd dancing roll lower ends, 45 ° of upsets for the first time are realized, 2 lower surfaces of reversing roller are entered back into from the lower end of the 3rd dancing roll, Equally, the gas of steam vent holds up paper tape, and paper tape is operated around the upper surface of the second twist rollers, passes through the upper table of the 4th dancing roll Face realizes second of 45 ° of upset, at this moment, and the paper tape come out from the device reforms into face-up, enters back into second unit Start front printing, so as to complete the overall process that printing paper band is overturn by back-to-front, it is ensured that positive back face printing operation will Ask.

Although this turning device can realize the turn-over of paper tape, when conveying device starts carriage tape, gas warp By air pump pipeline flow-direction reversing roller, it is necessary to be first full of could at the uniform velocity after reversing roller from steam vent discharge, and now paper tape has been Moved between rotating roller and reversing roller, because paper tape is pulled tight directly and is placed directly against rubbed on reversing roller in conveying Go, it may appear that paper tape is because of the excessive situation about being pulled off that rubs, therefore the device still has improved space.

Utility model content
