(3) summary of the invention

At the weak point of above-mentioned transfer printing machinery, the utility model provides a kind of natural fabric to shift seal, has dyed combination machine, and it can carry out prestainedly carrying out the single or double transfer printing simultaneously to fabric, and can guarantee clear patterns.

Its technical scheme is such: it comprises breast roll, pressure roller, charging gear, squeeze device, it is characterized in that: described pressure roller has two at least, adjoin along the circumference of described breast roll and with breast roll respectively, and breast roll is exerted pressure, described two pressure rollers and described breast roll adjoin the diameter that a little mostly is most breast roll in the arc length of described breast roll, pattern winding and textile web contact with each other and pass through between described breast roll and pressure roller.

Among the said structure of the present utility model, the combination of a breast roll and several pressure rollers, nonsynchronous problem can not appear so just, the cost of investment of equipment reduces, and between the pressure roller along the restriction of distance between the breast roll arc surface, the dislocation distortion can not appear when having guaranteed textile web and pattern winding through the adjoining of second pressure roller and breast roll, guarantee the definition of pattern, when the needs duplex pringing is shifted, two pattern winding are distributed in the both sides of textile web respectively and enter transition range with textile web get final product, and textile web carried out padding of dye liquor before entering transition range, keep certain wettability, so that the decal transfer of transition range, can realize dyeing and single or double decal transfer so simultaneously, can not realize the duplex pringing transfer in the existing equipment thereby can overcome, and can realize that the equipment manufacturing cost of duplex pringing transfer is high, and the shortcoming that the definition of pattern is difficult to guarantee.

(4) description of drawings

Fig. 1 is a structural representation of the present utility model.

(5) specific embodiment

See Fig. 1, the utility model comprises breast roll 10, pressure roller, charging gear, squeeze device, pressure roller has at least two (to have two among Fig. 1, be respectively 5,9) adjoin along the circumference of breast roll 10 and with breast roll 10 respectively, and breast roll 10 is exerted pressure, pressure roller 5,9 with breast roll 10 adjoin the diameter that a little mostly is most breast roll 10 in the arc length of breast roll 10, textile web is wound off by the unwind roll in the charging gear 1, the pattern winding is by the unwind roll in the charging gear 3,8 launch, when the needs duplex pringing is shifted, use unwind roll 3 simultaneously, 8, when only needing bloth printing, unwind roll 3,8 can choose one wantonly, textile web contacts after winding is unfolded with pattern, be directed entering together pressure roller 9,5 with the transfer area of breast roll 1, textile web enters transfer area behind process unwind roll 1 before, textile web passes squeeze device, textile web is dipped into liquid bath 11, pass through the rolling of a pair roller 2 subsequently, shut out unnecessary maceration extract, obtain the residue humidity of regulation thus, textile web and pattern winding are with higher speed combination, be transported to the transport zone of breast roll 10 and pressure roller 9, textile web and pattern winding are compacted through first pressure roller 9 time, pattern in the pattern winding is transferred and is imprinted on textile web, the transfer area that this moment, textile web and pattern winding were entered second pressure roller 5 and breast roll 10 by fixed relative to one another combining reliably, because the distance between first pressure roller 9 and second pressure roller 5 is shorter, when the pattern winding does not also have enough time to be out of shape, pattern winding and textile web another adjoining a little through second pressure roller 5 and breast roll 10, be applied in a high linear pressure again at this, thereby the transfer printing effect is enhanced, at last, pattern winding and textile web are respectively by take up roll 6,4 and 7 roll.Take up roll 6,4 can be chosen one wantonly in bloth printing is shifted.And fabric directly enters transition range after padding, so fabric can not spend, thereby carries out the transfer of single or double stamp when can guarantee to realize dyeing.
