Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.
A kind of printing machine online cold wave jumping device that the utility model embodiment provides, comprising: unwinding device, wrap-up, two anilox roll and four groups of driving mechanisms; Wherein, described unwinding device and wrap-up are respectively used to put, receive electrochemical aluminum foil; Enter and leave at electrochemical aluminum foil on the path of printing element and be respectively arranged with a described anilox roll; Described anilox roll is arranged between the wallboard of printing machine both sides, and its two ends connect respectively one group described in driving mechanism, described anilox roll can be under the driving of described driving mechanism be slided along the guide groove on the wallboard of printing machine both sides.
With reference to figure 1, it is the printing machine online cold wave jumping device schematic diagram of the utility model embodiment.
The jumping device of the utility model embodiment is applied in printing machine online cold wave, is arranged on the printing machine with cold wave unit.Concrete, referring to Fig. 1, in the printing element of printing machine, by blanket cylinder 9 and impression cylinder 10 to having rolled printing process.Owing to needing clamping different objects on different cylinders, on blanket cylinder 9, fill blanket, impression cylinder 10 carries paper in the time of printing, so blanket cylinder 9 and impression cylinder 10 exist neutral gear in to the process of roll printing brush, in to the process of roll printing brush, for some time not for printing.In general printing machine, with the cylinder of 360 degree, the angle of neutral gear is 100 about degree, and at neutral gear place when rolling, blanket cylinder 9 does not contact with the surface of impression cylinder 10.
The feature of utilizing above-mentioned printing neutral gear, the jumping device of the present embodiment comprises: unwinding device 1, wrap-up 2, two anilox roll 3 and four groups of driving mechanisms.Electrochemical aluminum foil 7 is emitted by unwinding device 1, regained, and it is through the tangent place of periphery of blanket cylinder 9 and impression cylinder 10 by wrap-up 2, coordinate the two to rolling into row cold wave.Enter and leave blanket cylinder 9 and impression cylinder 10 at electrochemical aluminum foil 7 and be respectively arranged with an anilox roll 3 on to the path at the place of rolling.Concrete, on printing machine both sides wallboard (wallboard is not shown in Fig. 1), being relatively set with a pair of guide groove 8, anilox roll 3 two ends are slidably connected in described guide groove 8.The two ends of each anilox roll 3 respectively connect one group of driving mechanism.
With reference to figure 1 and Fig. 2, wherein, Fig. 2 is the driving mechanism schematic diagram of the utility model embodiment.
As preferably, in the present embodiment, driving mechanism comprises: cam 4, cam swing 5 and connecting rod 6.Cam 4 contacts with cam swing 5 is tangent, and cam swing 5 one end and printing press wall board are hinged, and the other end is hinged to one end of connecting rod 6, and roll shaft one end of the other end of connecting rod 6 and anilox roll 3 is hinged.Cam 4 is through gear drive and the synchronized rotation of impression cylinder 10.In cam 4 rotation processes, keep tangent with cam swing 5 all the time and contact, and by the transmission of cam swing 5 and connecting rod 6, further drive anilox roll 3 in the interior slip of guide groove 8.
Driving mechanism drives two anilox roll 3 to slide along guide groove 8, now, electrochemical aluminum foil 7 is an aggregate velocity with respect to the speed of impression cylinder 10, and it equals the development rate (being determined by unwinding device 1 and wrap-up 2) of electrochemical aluminum foil 7 and the sum velocity of anilox roll 3 sliding speeds.In the time that printing machine enters neutral gear, anilox roll 3 sliding speed directions are contrary with the expansion direction of electrochemical aluminum foil 7, and anilox roll 3 and electrochemical aluminum foil 7 be in the other direction in sliding processes, and electrochemical aluminum foil 7 shows as and reduces gradually and be finally zero with respect to the speed of impression cylinder 10; Subsequently, the glide direction of anilox roll 3 transfers to identical with the expansion direction of electrochemical aluminum foil 7, and electrochemical aluminum foil 7 is with respect to the speed of impression cylinder 10 then increase gradually, until the speed of its speed and impression cylinder 10 is when identical, printing machine finishes neutral gear, proceeds printing, cold wave.
By preferred embodiment of the present utility model, and with reference to figure 1 and Fig. 2, printing machine online cold wave of the present utility model is as follows by jumping device specific works process:
Under original state, two anilox roll 3 right-hand member in guide groove 8, is also the right side extreme position of anilox roll 3.Controlled by unwinding device 1 and wrap-up 2, electrochemical aluminum foil 7 normally launches, and prints and cold wave rolling to coordinate with blanket cylinder 9 and impression cylinder 10.In the time that printing machine enters neutral gear, four groups of driving mechanisms work at two anilox roll 3 two ends, concrete for every group of driving mechanism, cam 4 starts to rotate, contact cooperation by cam 4 with the tangent of cam swing 5, and the transmission of connecting rod 6, anilox roll 3 is slided left along guide groove 8.Two anilox roll 3 are left in sliding process, the overall transfer path of electrochemical aluminum foil 7 moves to left accordingly along with the slip of anilox roll 3, electrochemical aluminum foil 7 shows as gradually and diminishes with respect to the speed of impression cylinder 10, when anilox roll 3 slides into the left end of guide groove 8, left side is when extreme position, and the speed of anilox roll 3 reduces to zero; Next, be subject to the traction that cam 4 rotates, anilox roll 3 transfers to start reverse slide, return to original state, when sliding into the right-hand member of guide groove 8, now the speed of electrochemical aluminum foil 7 is identical with the Roller conveyor speed of impression cylinder 10, simultaneously, printing machine finishes neutral gear, again enter roll printing brush, cold wave, anilox roll 3 drive under by guide groove one end start to slide into the other end and again the time of initial position identical with the time dead of press printing.Realize accurately carrying out of said process, according to concrete printing machine model, by selecting the cam 4 of different size, the cam swing 5 of different length and connecting rod 6, and the slotting length of guide groove 8, the concrete numerical value setting of each part mentioned above is no longer described in detail in embodiment of the present utility model.
Said process back and forth carries out, realize the online cold-foil process of the printing machine of the jumping device that the utility model embodiment is set, and at printing machine during in neutral gear, the development rate of electrochemical aluminum foil 7 reduces, be even zero, fully improved the utilization rate of electrochemical aluminum foil 7.
Those of ordinary skill in the field are to be understood that: the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle; any amendment of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
