Description

Technical Field

[0001] The utility model relates to the technical field of PET thermal transfer film production, and more specifically to a PET thermal transfer film production and reeling device. Background Art

[0002] PET thermal transfer film is a special film material used for thermal transfer printing, usually composed of a polyester (PET) substrate and a heat-sensitive transfer layer. During the thermal printing process, the pattern or text in the transfer layer is transferred to the printed material through hot pressing to achieve the printing effect. The PET thermal transfer film production and rewinding device is a device used to produce PET thermal transfer film, which is convenient for rewinding the PET thermal transfer film after production.

[0003] The existing PET thermal transfer film production and winding device still has the following problems: the existing PET thermal transfer film production and winding device has poor adjustability when guiding PET thermal transfer films of various widths, and personnel need to manually adjust the width of the roll back and forth, which is very cumbersome. In the actual production process, the PET film usually needs to be heated for shaping, coating or other processing operations. These processing processes will provide the PET film with the required shape and performance, but will also cause the film to become soft, which is very likely to cause the film to curl excessively after winding, affecting product quality;

[0004] Moreover, after the existing PET thermal transfer film is produced and rolled up, the winding shaft bears a large weight due to the heavy weight of the coil, which can easily lead to damage to the winding shaft in the long run. Secondly, multiple people are required to unload the coil, which not only wastes a lot of manpower, but also reduces its unloading efficiency.
