Abstract
The utility model discloses a paper reeling mechanism for printing machines, which comprises an unreeling roller, a reeling roller and a plurality of stretch rollers between the unreeling roller and the reeling roller. Wherein, these stretch rollers are symmetrically arranged and each stretch roller has a shape of a thin middle part and two thick ends, thus preventing deformation of webs or films during unreeling and reeling due to tension and enabling the paper reeling mechanism to realize two functions of unreeling and reeling. Upon printing once by a printing machine, the paper reeling mechanism quickly finishes unreeling on the printing machine without removing the reeling roller and then reeling by other means, thus improving printing efficient of the printing machine.
Description
Technical field
The utility model relates to printing machinery, relates in particular to the coil paper mechanism of printing machine.
Background technology
In printing process, when the various pattern that has printing or other modes to form on roll web or the film, if want to reuse this roll web or film, then after the first impression is finished, must carry out backrush exactly, the accuracy of pattern direction and position when guaranteeing to print once more.
And folk prescription can only be accomplished to coil paper by existing coil paper mechanism, promptly can only unreel the coil paper of direction, and can not finish the coil paper of backrush direction exactly.This is main because the diastole roller of existing coil paper mechanism only has the effect of folk prescription to the diastole roll web, in the backrush process, can't carry out diastole to roll web or film.Therefore, existing printing machine, in printing process, when one-step print finishes, after roll web or film are all transferred to wind-up roll by let off roll, can not finish backrush at once, finish backrush but wind-up roll need be lifted down by additive method, such process makes that the printing efficiency of printing machine is lower.
The utility model content
The purpose of this utility model aims to provide a kind of coil paper mechanism of printing machine, this coil paper mechanism can not only unreel the coil paper of direction, and can finish the coil paper of backrush direction, make printing machine finish the back and just can on printing machine, finish backrush rapidly, to improve the printing efficiency of printing machine at one-step print.
To achieve these goals, the coil paper mechanism of printing machine of the present utility model is installed on the press rack, comprises let off roll, wind-up roll, and a plurality of diastole rollers between let off roll and wind-up roll, it is characterized in that: described diastole roller is middle thin two pluckings symmetric shapes.
The diastole roller adopts above-mentioned shape, not only can guarantee the tight and unlikely distortion in the process of unreeling of roll web or film, also can guarantee the tight and unlikely distortion in the backrush process of roll web or film, thereby make this coil paper mechanism can realize unreeling and two functions of backrush, printing machine is after one-step print finishes like this, this coil paper mechanism just can finish backrush rapidly on printing machine, need not wind-up roll is taken off by the alternate manner backrush again, has improved the printing efficiency of printing machine.
In further improvement of the utility model, the coil paper mechanism of printing machine of the present utility model also comprises two deviation correcting devices, and described let off roll and wind-up roll lay respectively on the deviation correcting device.These two deviation correcting devices can be controlled roll web or the reel film lateral deviation at traveling process, guarantee the accurately whole of roll web after the backrush or film, so that can directly enter printing again.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of diastole roller in the utility model.
Among the figure: 1, let off roll 2, wind-up roll 3, diastole roller 4, deviation correcting device 41, sensor 42, motor 43, table top
The specific embodiment
As shown in Figure 1, the coil paper mechanism of printing machine of the present utility model installs on the frame (not shown) of printing machine, and this coil paper mechanism is made of a let off roll 1, wind-up roll 2, a plurality of diastole roller 3 and two deviation correcting devices 4.
Wherein, a plurality of diastole rollers 3 are between let off roll 1 and wind-up roll 2, and this diastole roller is middle thin two pluckings symmetric shapes.Diastole roller 3 adopts above-mentioned shape, not only can guarantee the tight and unlikely distortion in the process of unreeling of roll web or film, also can guarantee the tight and unlikely distortion in the backrush process of roll web or film, thereby make this coil paper mechanism can realize unreeling and two functions of backrush (among Fig. 1, solid arrow represents to unreel direction, dotted arrow is represented the backrush direction), printing machine is after one-step print finishes like this, this coil paper mechanism just can finish backrush rapidly on printing machine, need not wind-up roll is taken off by the alternate manner backrush again, improved the printing efficiency of printing machine.
Described let off roll 1, wind-up roll 2 lay respectively on the deviation correcting device 4, and these two deviation correcting devices 4 adopt deviation correcting device of the prior art, mainly are made up of sensor 41, control circuit (not shown), motor 42, table top 43.Wherein wind-up roll 2, let off roll 1 are fixed on the table top 43, sensor 41 is positioned at wind-up roll 2, let off roll 1 inboard oblique upper position, in order to monitoring cylinder paper or the lateral deviation of film in traveling process, control motor 42 pulling table tops 43 then and do corresponding mobile to adjust deviation.
Claims (2)
1, a kind of coil paper mechanism of printing machine, be installed on the press rack, comprise let off roll (1), wind-up roll (2), and be positioned at a plurality of diastole rollers (3) between let off roll (1) and the wind-up roll (2), it is characterized in that: described diastole roller (3) is middle thin two pluckings symmetric shapes.
2, the coil paper mechanism of printing machine according to claim 1 is characterized in that: also comprise two deviation correcting devices (4), described let off roll (1) and wind-up roll (2) lay respectively on the deviation correcting device (4).
