Description

DOPLEX PRINTABLE THERMAL SUBLIMATION TRANSTER PRESS}

The present invention relates to a heat-sublimation transfer press capable of double-sided printing, and more particularly, to a general-purpose three-dimensional heat-sublimation transfer press capable of high-quality double-sided printing regardless of the height of an object to be printed.

Conventional 3D vacuum press equipment draws vacuum from the bottom in an approximately rectangular box-shaped tray. In the case of transferring a high object to be printed in such a vacuum press equipment, image distortion may occur as the film is stretched, or a film may burst or tear due to insufficient elongation of the film. That is, in the convection heater of the vacuum press equipment, that is, the hot air circulation structure, hot air is not evenly transmitted due to the tray wall. In addition, the heat structure of the lamp heater is different depending on the distance to the printed object.

Accordingly, in recent years, research on various press equipments for improving the transfer quality with uniform heat transfer has been continuously conducted.

However, the present invention is not limited thereto, and it is natural that a modified example in which the printing space 11 and the vacuum space 12 are partitioned by the partition walls 10a side by side in the left-right direction of the main body 10 is possible.

The transfer operation of the double-sided heat-sublimable transfer press 1 according to the present invention having the above-described configuration will be described with reference to FIG. 5.

As shown in (a) of FIG. 5, the image to be printed on the object P is prepared by printing on the first and second films 221 and 231 using the printer C. The printed first and second films 221 and 231 are inserted into and fastened to the first and second print frames 22 and 23 in the form of a frame, as shown in FIGS. 5(b) and 5(c).

In addition, as shown in (b) and (c) of FIG. 5, first and second print frames 22 and 23 are provided, and the object P to be printed is supported on the support frame 21. At this time, the object to be printed (P) is fixed to the posture through the support frame 21 made of metal or composite plastic having fine pores 211a. In addition, in a state in which the object to be printed P is supported by the support frame 21, the printing space 11 inside the body portion 10 provided with the support frame 21 is preheated to a glass transition temperature. The first and second printing frames 23 in which the first and second films 221 and 231 are fitted in the preheated printing space 11 also remain for a certain period of time, thereby softening by preheating.

For reference, the interior of the printing space 11 is preheated by at least one of the first heating member 131 for generating convective heat with a glass transition temperature and the second heating member 132 for generating radiant heat, or the first And it can be preheated at the same time by the second heating member (131, 132).

When both the printed object P supported by the support frame 21 and the first and second films 221 and 231 supported by the first and second print frames 22 and 23 are preheated, FIG. As shown in (d), the first and second print frames 22 and 23 are moved toward the support frame 21 by the movable section 24. That is, the first and second print frames 22 and 23 are moved by the power of the drive source 242 along the rail 241, so that the first and second print frames 22 and 23 support frame ( 21).

The first and second print frames 22 and 23 are moved toward the support frame 21, so that the first and second films 221 supported and softened by the first and second print frames 22 and 23 are softened. ) (231) is in close contact with each other on one surface and the other surface of the object (P). At this time, the first and second films 221 and 231 are provided with a vacuum pressure V from the vacuum unit 30 in a state in which the printed object P is in close contact with the first and second films 221 and 221 ( 231) is in full contact with the object (P) to be printed.

Here, the first and second printing frames 22 and 23 are moved toward the object P in a movable rail structure without a wall, so that the heat of the heating means 13 is avoided as shown in FIG. It can be evenly applied to the printed material (P). That is, the first heating member 131 including the hot air circulation heater and the second heating member 132 including the quartz tube/IR lamp are the printed object P and the first and second films 221 and 231. Is heated with convective and radiant heat.

Therefore, the ink printed on the first and second films 221 and 231 is vaporized by heat and transferred to the object P. At this time, the vacuum pressure (V) of the vacuum unit 30 is applied through the vacuum hole 212a provided in the sealing body 212 that seals the side surface of the support plate 211 having fine pores 211a, so that the first And the second films 221 and 231 are completely in contact with the object P.

Here, due to the complex heating method that simultaneously uses convective heat of the hot air circulation and radiant heat of the lamp type, it is possible to uniformly print the object P while reducing the processing time. In addition, the heating efficiency can be improved by removing the existing support wall and making the support frame 21 as thin as possible so that the heat of the heating means 13 to the printed object P is exposed as much as possible.

As shown in (f) of FIG. 5, when the printing on the object P is finished, the first and second printing frames 22 and 23 are separated from the object P by returning to the original position, and thus the first and first 2 Films 221 and 231 are removed from the object P. Therefore, as shown in FIG. 5(g), double-sided printing is completed on the object P.

Referring to FIG. 6, the two-sided sublimation transfer method according to the movement method of the first and second print frames 22 and 23 supporting the first and second films 221 and 231 is sequentially shown.

6(a), after the first and second films 221 and 231 are mounted on the first and second printing frames 22 and 23 provided on both sides, the first and second printing frames (22) By rotating the drive source 242 provided between 23 and 23, the rails 241 and the first and second printing frames 22 and 23 connected in a serrated manner support rails 21 along the rails 241 ). That is, as shown in (b) of FIG. 6, due to the rotation of the driving source 242, the first and second printing frames 22 and 23 are centered along the rail 241 of the bar shape or It can spread outward.

As shown in (c) of FIG. 6, the vacuum pressure V is provided to the support frame 21 by the vacuum unit 30, so that the first and second printing frames 22 and 23 by the vacuum pressure V are provided. It is in close contact with the support frame 21 located in the middle. Therefore, as shown in (d) of FIG. 6, the first and second films 221 and 231 are in close contact with both surfaces of the object P having a three-dimensional shape, so that printing on both surfaces is possible at the same time.

7 sequentially shows a cross-section sublimation transfer method using a general-purpose three-dimensional heat sublimation transfer press 1 according to an embodiment of the present invention.

As shown in (a) of FIG. 7, the first and second printing frames (where the film 221 is mounted on one of the first and second printing frames 22 and 23 but the film 221 is not mounted) 22) The blocking member (B) for blocking the air is supported on the other of the (23). In this embodiment, it is illustrated that the first film 221 is supported on the first print frame 22 and the blocking member B is supported on the second print frame 23.

Then, as shown in (b) and (c) of FIG. 7, the first and second printing frames 22 and 23 are brought into close contact with the center along the rail 241 by the driving force generated from the driving source 242. do. In this case, as shown in (d) of FIG. 7, vacuum pressure (V) is applied to the second printing frame 23 where vacuum pressure V is applied only to the first printing frame 22 and air is blocked by the blocking member B. This is not applied. Therefore, the first film 221 supported on the first printing frame 22 is in close contact with only one surface of the object P, so that the image of the first film 221 is transferred to the object P to be printed. do.

On the other hand, when the object to be printed (P) has a three-dimensional shape having a height, the image distortion is severe due to the large strain of the film (221, 231), the conventional curved sublimation transfer (3D dye sublimation) vacuum press of normal quality Printing is impossible. In particular, when the height of the object P is higher than the height of the tray T supporting that the frame F1 supporting the conventional film F2 is movable, as shown in FIG. 8(a), it is not softened. It is difficult for the film F2 to be mounted on the frame F1. In addition, when the height difference between the height of the tray T and the object P is large, the film F2 is stretched and the film F2 is settled at the exact position desired by the user in the process of being seated on the object P. It does not work, and deformation occurs severely. Conventionally, the height of the tray T, that is, the height at which the film F2 is located and the height of the object P should be as close as possible, but as shown in FIG. 8(b), the printing frame 22 (23) according to the present invention ) The method of moving along the rail 241 and adhering to the printed object P may place the films 221 and 231 at a desired position regardless of the height of the printed object P.

In addition, in the case of printing on an object P having a high height, the height of the tray T is also increased at the same time, so that unnecessary film F2 may be stretched. Due to the elongation of the film F2, which is too high in the related art, the film F2 is torn or image distortion is severely caused, and the film F2 is also ruptured. However, the present invention can minimize the elongation of the films 221 and 231 by eliminating the need for a conventional tray (T) wall.

Once again, in the case of a vacuum press having a conventional tray T, heat was not evenly transferred to the film F2 due to the wall of the tray T, but in the case of the present invention, the film F2 is printed. In addition to being able to soften by preheating, uniform heating is possible by directly exposing the entire portion of the object P to be heated by the heating means 13. In addition, unlike the conventional single-sided vacuum press, the double-sided printing of the object to be printed P is possible at the same time, so that productivity can be improved more than twice.

As described above, although described with reference to preferred embodiments of the present invention, those skilled in the art variously modify and change the present invention without departing from the spirit and scope of the present invention as set forth in the claims below.
