Description

Technical Field

[0001] The utility model relates to the field of thermal paper production, in particular to a flattening device for thermal paper production. Background Art

[0002] Thermal paper is mainly used for making labels. It has a wide range of applications. Thermal paper needs to go through multiple processes to be produced. During the production process, the thermal paper will bend. The bent thermal paper will affect the production of the subsequent processes. Therefore, it needs to be flattened. At present, the bent thermal paper is flattened by a pair of rollers. This flattening method is relatively inefficient and the flattening quality is not high. It is not efficient in actual use and needs to be improved.

[0003] After searching, the China Patent Network discloses a flattening device for thermal paper production, and its authorization announcement number is CN212737281U. This patent can effectively flatten the thermal paper through different pressing rollers. After flattening, the thermal paper is rolled up on the main wheel and waits for the next processing. Through the drop between the two auxiliary structures, the thermal paper can be stretched to a certain extent while being conveyed, so that the thermal paper is preliminarily flattened, thereby making the flattening efficiency higher. The main wheel is driven by a motor to rotate, so that the thermal paper is rolled on the main wheel, and the thermal paper is driven to move at the same time, so that the thermal paper can smoothly move between the auxiliary structure, the flattening structure and the rolling structure. The above can effectively solve the current problem that the bent thermal paper is flattened by a pair of rollers. This flattening method has low efficiency and low flattening quality. It is not efficient in actual use, and the structure is relatively simple, so that it has no considerable practical effect. Technical problems;
