Specific embodiments
Such as Fig. 1 to shown in Figure 5, a kind of device for smoothening sheets for the road motion of printing chain, by vacuum pump 10, quick connector 12, tracheae 13, all press box 15 and variable valve 14 to be formed, this device for smoothening sheets comprises that air draught flattens board component, gas path device.
Air draught of the present utility model flattens board component and is made of upper airdraft plate 1 and lower airdraft plate 2, establishes the gap between the upper and lower airdraft plate and forms detection mouth 4, detects confession CCD collected by camera unit inspection and uses.Air draught flattens board component and is positioned on the side lower part body of printing machine collecting cylinder.Spacing distance is provided with several tricky tooth grooves 3 on the front panel of upper and lower airdraft plate.Tricky tooth groove of the present utility model is 11 that spacing distance distributes.The effect of tricky tooth groove is to pass through for the tricky tooth band that printing machine transmits paper.Upper and lower airdraft plate adopts and makes smooth smooth scuffing and the pollution that can effectively prevent printing sheets through the corrosion resistant plate of polishing.Tricky tooth groove detects the air-breathing through hole 9 that gathers on the upper and lower airdraft plate of mouthful both sides outward and forms the negative-pressure air-suction fields.The rear panel of upper and lower airdraft plate is provided with three independently left air draught chamber 7, middle air draught chamber 5 and right air draught chambeies 6, the communicate air-breathing through hole of the opposed area on the negative-pressure air-suction field of each air draught chamber.Upper and lower airdraft plate rear side upper and lower part is fixing with upper seize 20 and lower seize 26 respectively by support 21 and 25, and upper seize and lower seize are separately fixed on the upper pulling shaft 19 and lower pulling shaft 16 on the body.Thereby making air draught flatten board component is fixed on the side lower part body of printing machine collecting cylinder.
Described upper and lower airdraft plate is surface plate.Described negative-pressure air-suction field is positioned on the upper and lower airdraft plate that detects mouthful both sides, the diameter that distribution one its axis of row and this flattening board plane angle are acute angle on the upper and lower airdraft plate of adjacent detection mouthful both sides is numerous the counterbores 8 of 3～5mm, and each counterbore sidewall is provided with the air-breathing through hole 9 of a 1～2mm.Distribution diameter is numerous the air-breathing through holes of 1～2mm on the upper and lower airdraft plate of counterbore rear side.The described width that detects mouth is 3～5mm.The axis of described each counterbore and this flattening board plane angle are 20o～80o.The said structure design is beneficial to the expansion of paper.
As shown in Figure 4, gas path device of the present utility model is used for the negative-pressure air-suction field is produced negative pressure, by vacuum pump, quick connector, tracheae, all press box, wire rubber pipe 25 and variable valve to be consisted of.The bleeding point of vacuum pump is successively by wire rubber pipe 11, all press box, pressure regulator valve and quick connector and tracheae to communicate with each air draught chamber respectively.Obviously, communicate each the air-breathing through hole of the opposed area on the negative-pressure air-suction field of left air draught chamber, middle air draught chamber and right air draught chamber leading flank, each face of all the other of each air draught chamber are sealing surface and respectively by finally the communicate bleeding point of vacuum pump of each tracheae.
As shown in Figure 5, the utility model is used in traditional printing machine collecting cylinder 17 positions, also is provided with printing machine lateral paper guide 18, upper pulling shaft 19, upper seize 20, lower pulling shaft 16 and lower seize 26 on the printing machine body 24 at this position.The printing machine body is fixed on the base 23.CCD collected by camera unit 22 also is positioned on the body of air draught flattening plate downside.
During use, open vacuum pump, through the turnover air quantity of initial debugging vacuum pump, reaching breadth is that 800mm * 600mm opens greatly printing paper when flattening board component by air draught, can be adsorbed on the upper and lower airdraft plate, can drag steady movement along with the tricky tooth band of printing machine again simultaneously.The bleeding point of vacuum pump makes each air-breathing through hole also produce negative pressure by each air draught being crossed exhausting, form the negative-pressure air-suction field on the upper and lower airdraft plate, a large printing paper flattens when flattening board component by air draught, makes the CCD camera collect stable clearly image by detection window.
When the tricky tooth band of printing machine is being held printing sheets by upper and lower airdraft plate in the month, the spacing of printing sheets and upper and lower airdraft plate is the 1-2 millimeter, the negative pressure that upper and lower airdraft plate surface forms is adsorbed on printing sheets on the upper and lower airdraft plate, guarantee printing sheets along with the undeformed steady movement of dragging of tricky tooth band, guarantee that printing quality on-line detecting system CCD camera collects stable clearly image by this device detection window.Realize that pixel resolution detects up to the high precision image of 0.08mm * 0.08mm/pixel.
When printing machine started operation, device of the present utility model also simultaneously startup entered duty, install simply, and reliable operation, easy to operate.
In a word, the utility model has been realized the paper surface flattening of large format by the sprocket wheel motion, has guaranteed that the CCD collected by camera to stablizing HD image, also has reasonable in design, and simple to operate, Installation and Debugging are convenient, detect the measured advantage of matter.Can promote the use of.
