Description

200417475 V. Description of the invention (1) Technical field to which the invention belongs The present invention provides a method of heat transfer printing, especially a method for transferring an image on a photo paper to a cup of noodles. Prior art

After the technology of mass production in industrial society matures, various products are gradually moving towards differentiated designs. Therefore, the demand for appearance design and personalized products has arisen at the historic moment, and various personalized products are now sold in many different types. For example, advertised the transfer of personal life photos to various products such as mugs, clothes, backpacks, and stationery, but there is still much room for improvement in the quality of transfer, especially the surface of the transfer receiving article is not a flat surface. For curved surfaces, cylindrical items such as cups often suffer from poor transfer quality due to the inability of the paper and cup surface to adhere tightly during transfer. Today, consumers are using Dye Diffusic cameras (Dye Diffusic ^

Thermal Transfer Printer) or Jet Printer to output images or text Hot Decal on photo paper to the cup surface of a container such as a mug, mug or glass or other cylindrical outside In the process of molding surface, it is often found that there are fine bubbles between the cup surface and the photo paper, and the bubble volume will expand with the increase of temperature during the hot pressing transfer process, causing a gap between the paper surface and the cup surface to affect The quality of the hot-pressed transfer image.

Page 7 200417475 The slight difference between the image or text on hot paper and the cup noodles 'Generally, after making the cup noodles, that is, in a warm state, tearing the phase effect without turning it completely', then stick the photo paper to this After operating under high temperature conditions, it is easy to cause the images to overlap, and then it is heated until the knife is on the back of the photo paper. However, this method is dangerous because of the degree and it is scraped, and some areas have been scraped off; The method of removing light with nail polish removes the time. V. Description of the invention (2) In the past, when photographic paper was used, it was often left to suffer from the quality of the photo. If there is a bubble, the image is not completely transferred and then transferred again. In addition to the danger of degree, it is also stuck on the mug surface under high temperature. The air bubbles in the paper are scraped off. In some areas, there are removed air bubbles that escape to bad patterns that need to be re-transferred. And the above is not easy to control. SUMMARY OF THE INVENTION Air bubbles transferred to a mug affect the thermal transfer by the following methods. It is heated, and the shadow on the photo paper is observed and moved to the mug. If it goes back, put it in a hot press for 'except for considerable distance distortion. The second is to put the photo paper on the photo paper and the mug will be in the Cup noodles and phases are often scratched under high temperature conditions, and the paper and mark are not scratched. Even if the wiper transfers water and thin cloth to remove the waste on the old, it is a hot press transfer method. Therefore, the main object of the present invention is to provide a method to solve the above problems. 200417475 V.

Let the horse drive two = 2 groups 40 rotate the bearing seat 22, and rotate the cup 2 from the middle of the photo paper to the ρ ″ end ^ 忮, and at the same time use the clamping mechanism 24 to push the 2 seat 30 to make the spring 36 belt The moving roller wheel 34 is perpendicular to = 2 200417475 V. Description of the invention (6) Surface 3 rolls out the air bubbles between the photo paper 4 and the cup surface 3 to completely transfer the image on the photo paper 4 to the cup surface 3 ' In order to overcome the problem that the image on the photo paper 4 cannot be completely transferred to the cup noodle 3 due to the obstruction of the air bubbles in the prior art; Step 78: After performing step 76, a heating device is used for the photo paper 4 and the cup noodle. 3 for hot-press transfer, heating temperature is about 150 ° C. The heating time is controlled to about four minutes to completely transfer the image of the photo paper 4 to the cup surface 3 ', and the heating device can be preheated. Device 8 or any type of heat press transfer machine, etc .; and step 8 0 · After performing step 7 8, remove the photo paper 4 from the cup noodle 3, and then complete the heat press transfer of the image of the photo paper 4 The process of printing to the cup surface 3. The clamping mechanism 24 includes a push-pull clamping rod (pUSh-pUii ciamp) 2 6 and a guide bar set 28 (guide bar), which is connected between the bearing slide 30 and the push-pull clamping rod 26, and the bearing slide 3 The two slide grooves 32 of 〇 are two openings. When an external force is applied to the push-pull clamp lever 26, the push-pull clamp lever 26 transmits the external force to the guide rod group 28 and then the guide rod group 28. The force reaches the bearing slide 30, and the bearing slide 30 drives the second spring 36 to push the roller 34 to slide in the chute 32 so that the roller 34 is pushed toward the cup noodle 3 in a manner perpendicular to the cup noodle 3 The photo paper 4 and the cup surface 3 can be closely attached. In the first embodiment, the cup 2 can be rotated in many different ways, not only by the motor 38 and the gear set 40. For example, when the grain wheel 34 is pushed toward the cup surface 3, The user can rotate the cup 2 by hand or turn the carrier 30 by hand to rotate the cup 2 without using the motor 38 as the motive force.

Page 12 200417475 V. Description of the invention (7) Turn the cup 2. The second embodiment of the present invention uses a manual method to remove air bubbles between the photo paper 4 and the cup surface 3 by a roller 34. The second embodiment also takes the same steps 60, 62, 64, 68, 70, 72, 74, 78 and &

Step 80 is different from the first embodiment in that steps 66 and 76 are changed to manually remove air bubbles between the photo paper 4 and the cup surface 3 by a roller 34. Please refer to FIG. 6, which illustrates a schematic diagram of removing air bubbles between the photo paper 4 and the cup surface 3 by the roller 34 according to the second embodiment of the present invention. As shown in the figure, the photo paper 4 is flatly adhered to the cup surface 3 of the cup 2 with the thermal tape 6. The cup 2 with the photo paper 4 pasted is placed on the carrier 2 2, and the carrier 2 2 is fixed to the base. Block 2 0. The rollers 3 and 4 are closely adhered to the surface of the photo paper 4 manually, and the rollers 3 and 4 are applied along the surface of the paper 4 to apply vertical pressure. The pre-generated micro-prospecting of the transferred image surface is carried out by rotating the cup roll, and the paper surface of the photo paper lies in the dangerous distortion of the cup surface under the conventional hot pressing industry. This method is hot, so that the paper is made of paper, and the surface of the paper is completely affixed to the paper while the surface is completely adhered to the paper, and the air transfer method between the paper and the paper is repeated. It is slightly viscous, so it is gas, and it drops. Before printing and scraping out the air, the material passes through a suitable amount of rubber cup noodles. Therefore, the air bubble cannot be easily and the method of low heat pressure is used. The space covered by the rubber rollers will bleed back, effectively printing distortion, which can avoid the paper and the cup pre-heating and rolling, and air bubbles can eliminate the storage
