Description

Technical Field

[0001] This application relates to the technical field of thermal transfer, and particularly to a swing-type thermal transfer machine with automatic blanking. Background Art

[0002] Thermal transfer is a very mature printing process. It pre-prints a color pattern on a heat-resistant substrate film, and then, in cooperation with a special transfer machine, transfers the pattern on the substrate film to the surface of the product by hot stamping. The printed pattern has the characteristics of rich layers, bright colors, ever-changing, and small color difference, which can well meet the requirements of designers and is suitable for the needs of modern large-scale production.

[0003] To meet the processing of some cylindrical products with taper, a swing-type thermal transfer machine has been designed. By setting a swing frame on the frame and arranging a film feeding roller and a film winding roller on the swing frame, during the transfer process, the swing frame swings left and right, so that the pattern on the transfer film is transferred to the substrate along a fan-shaped direction, ensuring that the transferred pattern can be accurately attached and transferred to the substrate with taper, and ensuring that the pattern is not deformed or wrinkled.

[0004] For example, the Chinese patent with the authorization publication number CN214646700U and the publication date of November 9, 2021 discloses a multi-station up-and-down swing thermal transfer machine for taper products, including a workbench and a main frame. At the front end of the top of the main frame, a film guiding frame is provided. The film guiding frame includes an intermediate connecting frame in the middle and a film winding frame and a film feeding frame located at the left and right ends respectively. A swing frame is arranged in the middle of the film guiding frame. A thermal transfer main machine mechanism is arranged at the lower end of the swing frame. A thermal transfer head is arranged at the bottom of the thermal transfer main machine mechanism. A front and rear driving mechanism of the film guiding frame is arranged on the swing frame. A horizontal swing driving mechanism of the swing frame is arranged on the main frame. At the front end of the lower part of the main frame, a rotating disc is provided. A plurality of connecting sleeve molds for positioning the thermal transfer barrel body are arranged at equal angles on the same circumference of the front end face of the rotating disc. The connecting sleeve molds are located below the thermal transfer head. A first driving mechanism for driving the rotation of the rotating disc is arranged at the rear side of the rotating disc. A second driving mechanism for driving the rotation of the connecting sleeve mold is arranged at the rear side of the connecting sleeve mold.

[0005] The above application drives the swing frame to rotate during the transfer process by setting a horizontal drive for the swing frame, ensuring the accuracy of the transferred pattern. At the same time, a rotating disc is arranged on the main frame and a plurality of connecting sleeve molds are installed through the rotating disc. During the thermal transfer process of the substrate on one connecting sleeve mold, the substrates on other connecting sleeve molds can simultaneously complete the feeding and blanking operations, saving time and improving the processing efficiency.

[0006] Regarding the related technology described above, the inventor believes that although the application is provided with multiple connecting sleeve molds, which can reduce the time for machine loading and unloading, during the processing of this equipment, manual feeding and unloading are still required frequently, resulting in a large labor intensity. Therefore, it is necessary to design a swing-type heat transfer printing machine with automatic unloading, which saves time and effort. Summary of the Invention
