Description

Technical Field

[0001] The present invention relates to the technical field of textile fabric body hot stamping and printing, and particularly to a digital hot stamping and printing machine for textile fabrics with positioning and anti-offset functions. Background Technique

[0002] When producing a textile fabric body, in order to print various patterns on the formed fabric of raw materials, in the past, different silk screens or spraying mechanisms were used to evenly cover different areas on the fabric to form patterns. With the progress of technology, digital hot stamping and printing machines are used for printing on fabrics, and the printing is clearer and can be retained for a longer time, reducing printing defects. However, during use, it is not convenient to control the stability of printing, which easily causes offset between the fabric and the transfer material, affecting the final production forming effect.

[0003] To overcome the above defects, there is a prior art (a Chinese patent application with the application number CN202011268032.1 and the application date November 13, 2020) for a water-resistant clothing fabric printing method and its device. When the gilded fabric for printing passes through the inside of the drying cylinder, the hot air flow generated by the hot air blower dries the printing ink marks, achieving rapid drying of the ink and facilitating the timely winding of the printed fabric. At the same time, the gas inside the drying cylinder enters the inside of the purification box under the action of the induced draft fan. The activated carbon adsorption core first adsorbs and filters the particulate matter in the waste gas, and then the pollutants in the waste gas contact and react with the cleaning liquid for secondary purification. The purified gas is discharged through the exhaust pipe, greatly reducing the emission and diffusion of polluting gases and being beneficial to improving the environmental protection of the fabric printing device. There is also a prior art (a Chinese patent application with the application number CN202223200245.8 and the application date November 30, 2022) for a gilding printing machine for fabrics. It reasonably utilizes the induction of the main temperature sensor and transmits a signal to the control part. The control part is used to control the start of the main blower and the main heating wire, and the air flow is transmitted into the air outlet plate through the main blower, further improving the transmission effect of the air outlet plate. When the air flow enters the air outlet plate, the air flow is heated by the main heating wire and then transmitted into the heat preservation box to achieve the heat preservation of the temperature inside the heat preservation box. By using the heat preservation box to keep the temperature, the situation of unstable temperature difference of the gilding roller is prevented, and the processing effect of the gilding roller is further improved. And there is a prior art (a Chinese patent application with the application number CN202223613506.9 and the application date December 31, 2022) for a gilding printing machine. It reasonably utilizes the main driving part to drive the rotating frame to rotate, and then the rotating frame drives the gilding paper piece and the gilding piece to rotate. By adjusting the positions of the gilding paper piece and the gilding piece, the accuracy of the position adjustment of the gilding paper piece and the gilding piece is further improved. After the positions of the gilding paper piece and the gilding piece are adjusted, the main push is started, and the support frame is driven by the main pushing part to drive the rotating frame to move above the fabric. Although the prior art can complete the gilding printing of the textile fabric body, during the working process, it is not convenient to position and prevent the offset of the conveyed textile fabric body, affecting the stability of fabric conveying. And when the fabric is slightly offset, it is extremely easy to cause the subsequent gilding printing to be offset, affecting the subsequent production, and it is also easy to cause different conveying forces at the edges of the fabric, resulting in slight deformation at the edges of the fabric, which also affects the gilding printing use.

[0004] In view of the above problems, there is an urgent need to innovate and design on the basis of the original digital gilding printing machine for textile fabric bodies. Summary of the Invention

[0033] During use, the conveying device assembled by the digital hot stamping printing machine frame 1 is used to convey the textile fabric body 3 and the transfer material 4. In cooperation with the hot stamping mechanism 2, the pattern on the transfer material 4 is transferred to the textile fabric body 3. After the transfer is completed, the useless transfer material 4 and the textile fabric body 3 are separated and wound up. When the transfer material 4 is conveyed, it bypasses the tension roller 7, and the height of the tension roller 7 is controlled through the cooperation of the slider 6 assembled on the tension roller 7 and the compression spring 8 in the first moving component 5, so as to control the tension of the transfer material 4. When the pattern on the transfer material 4 is numerous and delicate, different groups of the first moving component 5 can be assembled for precise conveying and to reduce damage to the pattern.

[0034] Embodiment 2: As Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6Based on the first embodiment, the disclosed technical solution further discloses the micro-adjustment when the textile fabric body 3 is offset. The specific content is as follows: The second moving component 9 is installed on the lower side of the inner surface of the digital hot stamping and printing machine frame 1, and the second moving component 9 is provided with an anti-offset adjustment mechanism; the anti-offset adjustment mechanism includes a large threaded rod 10 rotatably connected to the inner surface of the second moving component 9, and a moving frame 11 is threadedly connected to the outer surface of the large threaded rod 10.

The universal coupling 15 and the textile fabric body 3 form a conveying structure. At the same time, the coupling rotating roller 16 and the universal coupling 17 form a rotation structure through a connecting block; a moving member 1701 is rotatably connected to the outer surface of the universal coupling 17. A second moving block 18 is linearly and limitedly telescopically connected to the outer surface of the moving member 1701. A small threaded rod 19 is threadedly connected between the second moving block 18 and the moving member 1701.

And during normal operation, the central axes among the universal coupling one 15, the coupling rotating roller 16, and the universal coupling two 17 will coincide to control the stable conveying of the textile fabric body 3.
