[0002] With the rapid development of the packaging industry, hot labeling technology, as an important part of product packaging, its efficiency and hot labeling quality have become key factors in improving productivity. Traditional hot labeling equipment mostly adopts a single-head hot labeling method, which has certain limitations in the hot labeling process, such as the inability to achieve continuous hot labeling, low production efficiency, and complex operation. Therefore, the development of a fully automatic hot labeling machine that can improve hot labeling efficiency, reduce labor intensity, and improve hot labeling quality has become an urgent need for the development of the industry.

[0041] There are two feeders 5, which are respectively mounted on two mounting panels 53 on the left and right sides of the top of the inverted L-shaped frame 2, and the feeders 5 are used to feed the thermal transfer hot label material tape to the hot label station 3;

[0042] The feeder 5 includes a servo motor 51 and a hot stamping material retaining spring pressure plate 52 driven by the servo motor 51; the servo motor 51 is fixed on a mounting panel 53; the hot stamping material strip is mounted on the hot stamping material retaining spring pressure plate 52, and the use of the servo motor 51 provides precise speed and position control to ensure the consistency and accuracy of the hot stamping process. The hot stamping material retaining spring pressure plate 52 is driven by the servo motor 51, which can accurately control the position and pressure of the hot stamping material and improve the quality of the hot stamping.

[0043] The installation panel 53 is provided with a guide frame 54 and a tape winding optical axis A55 fixed on the guide frame 54 and used to guide and convey the hot stamping material tape. The guide frame 54 is fixed with a tag tracking guide plate 56 and a tag tracking sensor 57 arranged opposite to the tag tracking guide plate 56; the tag tracking sensor 57 is installed on a mounting block 58 outside the guide frame 54. The guide frame 54 and the tape winding optical axis A55 ensure the smooth conveyance of the hot stamping material tape, avoiding the deviation and wrinkles of the material during the conveyance process.

[0051] The heat transfer hot label material strip is installed on two symmetrical feeders 5. When the machine is started, the feeder 5 feeds the hot label material strip into the hot label station 3. Due to the double-station design, when one station is hot labeling, the other station can also feed the hot label at the same time, and the continuous feeding of the feeder 5 can realize continuous operation. After the hot label material strip is delivered to the hot label station 3, the hot head assembly 6 and the hot label material spring presser 63 are pushed by the cylinder 61 to heat and apply pressure to the hot label material, and the label is thermally transferred to the product. The hot label material spring presser 63 presses the product when it works, which has the effect of freeing both hands. After the hot labeling is completed, the waste hot label material strip is pulled to the waste discharge hole 4 through the discharger 7 to keep the hot labeling machine clean and working continuously.

[0052] Due to the double-station design, when one station is hot-stamping, the other station can be hot-stamping at the same time, thus realizing continuous hot-stamping, greatly improving production efficiency. The double stations work at the same time, and compared with the single-head hot-stamping machine, the output can be nearly doubled. There is no need to use suction cups and swing hands to absorb the hot-stamping materials and transfer them to the products like traditional technology, which reduces the intermediate links, reduces the complexity of operation, and improves work efficiency. The double-head fully automatic hot-stamping machine can realize continuous operation, significantly improve production efficiency, and reduce production cycle. The double-station design makes the output higher than the single-head hot-stamping machine, which is suitable for mass production. It reduces tedious operations such as suction cup swinging hands, reduces the difficulty of operation, and reduces labor intensity. The double-head fully automatic hot-stamping machine has good stability, higher hot-stamping quality, and reduces the scrap rate. The double-head fully automatic hot-stamping machine has a high degree of automation, reduces labor costs, and improves the level of production automation.
