Abstract

The utility model relates to a drying cabinet device for an intaglio printing press which comprises an air inlet, an air outlet, an air nozzle and an arc end plate. The outlet of the air nozzle is turned outwards; the outlet forms an arc angle; the edge and the middle of the arc end plate are provided with meshes; the meshes on the arc end plate close to the air inlet are small and scattered; the meshes away from the air inlet are big and thick; and a lower air outlet is arranged under the air inlet of the drying cabinet close to the bottom of the cabinet. The drying cabinet device for the intaglio printing of the utility model has the advantages that the air speed can be increased by 3m/s, the drying effect is increased by 40% and the residual solvent strength is greatly lowered.

Description

A kind of intaglio press drying box device

Technical field

The utility model relates to a kind of drying box device, more particularly relates to a kind of intaglio press drying box device.

Background technology

Progress along with science and technology, the printing house is more and more higher to the speed of intaglio press, pure mechanical speed is easier to improve, yet, printed matter can not be in time dry in the raising along with print speed printing speed, and this just becomes the bottleneck that the intaglio printing motor speed improves, simultaneously, the residual solvent concentration of printing is bigger, seriously polluted to printed matter.

Summary of the invention

In order to solve the deficiencies in the prior art, the utility model provides a kind of intaglio press drying box device, and solving the printed matter exist in the technology that print speed printing speed improves constantly can't rapid draing, the problem that residual solvent concentration is bigger.

The purpose of this utility model is achieved through the following technical solutions: a kind of intaglio press drying box device, comprise air inlet, exhaust outlet, tuyere and arc-shaped end plate, the outlet outward flanging of tuyere, the exit forms arc chord angle, and the edge and the middle part of arc-shaped end plate are provided with mesh.

In the such scheme, even for guaranteeing the dry wind that blows on the intaglio plate, the mesh on arc-shaped end plate is arranged to little and thin near the mesh at air inlet place, be arranged to big and close away from the mesh at air inlet place.

In the such scheme,, below the drying box air inlet, be provided with exhaust outlet down near bottom half for solving the big problem of residual solvent concentration in the dry wind.

The utility model intaglio press drying box device compared with prior art, its beneficial effect is:

1, because drying box is provided with mesh, arc chord angle is arranged in the outlet of tuyere simultaneously, and wind speed can improve 3m/s, and drying effect improves 40%.

2, drying box has increased time exhaust outlet, and residual solvent concentration reduces significantly.

Among the figure, 1. exhaust outlet, 2. air inlet 3. descends exhaust outlet, 4. little mesh, 5. mesh, 6. big mesh, 7. tuyere, 8. arc chord angle, 9. air channel, 10. transition air channel, 11. air channels, 12. tuyere pipes, 13. arc-shaped end plates.

The specific embodiment

Below in conjunction with drawings and the specific embodiments a kind of intaglio press drying box of the utility model device is further described:

Among Fig. 1, upper side at drying box is provided with exhaust outlet 1 and air inlet 2, exhaust outlet 3 down is set in 1/3rd positions, bottom of drying box, one side near air inlet 2 on arc-shaped end plate 13 is provided with little mesh 4, the aperture of little mesh 4 is little and arrange sparse, one side away from air inlet 2 on arc-shaped end plate 13 is provided with big mesh 6, the aperture of big mesh 6 is big and arrange dense, middle part at arc-shaped end plate 13 also is provided with mesh 5, and the pore size of mesh 5 and arrangement density are between little mesh 4 and big mesh 6.End face at arc-shaped end plate 13 is provided with a plurality of tuyeres 7, and tuyere 7 is arranged in parallel up and down.

Fig. 2 is the E-E cutaway view of Fig. 1, and among the figure, air channel 9 and air channel 11 communicate by transition air channel 10, and tuyere pipe 12 is arranged on the place ahead in transition air channel 10, and the two ends of tuyere pipe 12 communicate with air channel 9 and air channel 11, and little mesh 4 and big mesh 6 are arranged on the arc-shaped end plate 13.

Fig. 3 is the A-A cutaway view of Fig. 1, and among the figure, tuyere pipe 12 is arranged side by side along arc-shaped end plate 13, and the tuyere 7 of mouth pipe 12 is exposed to the outside of arc-shaped end plate 13.

Fig. 4 is the partial enlarged view of B among Fig. 3, among the figure, and the outlet outward flanging of tuyere 7, the exit is made into arc chord angle 8, makes the dry wind minimizing drag energy that comes out from drying box blow on the gravure printing roller of printing machine from tuyere 7 smoothly.

Fig. 5 and Fig. 6 are respectively the partial enlarged views of C and D among Fig. 2, and among the figure, the aperture of little mesh 4 is little and arrange sparsely, and the aperture of big mesh 6 is big and arrange dense.

In the work, after dry air enters casing by air inlet 2, through air channel 9, transition air channel 10 and air channel 11, discharge by tuyere 7 by mouth pipe 12 again, directly blow on the gravure printing roller of printing machine, turn back in the drying box through too small mesh 4 and big mesh 6 and mesh 5 again, because the mesh near the air inlet place is little and thin, mesh away from the air inlet place is big and close, make that the wind wind speed that blows out from tuyere is even, play the effect that automatic adjusting blows to the wind speed of dry face, so that identical to the wind speed of dry face.Simultaneously,, make dry wind, reduced the windage at tuyere place, avoided the loss of wind speed in the air outlet place of tuyere 7 smooth transition because arc chord angle 8 is arranged in the exit of tuyere 7.

Exhaust outlet 3 down is set in the bottom of drying box, in printing process, according to containing the heavier principle of the bigger gas of residual solvent concentration, make the residual solvent of drying box inside in printing process discharge drying boxes, thereby make the residual solvent amount on the printing satisfy national standard from following exhaust outlet 3.

Use this drying box, wind speed can improve 3m/s, and drying effect can improve 40%.
