Description

Technical Field

[0001] The utility model belongs to the technical field of printing processing, and particularly relates to an automatic lifting printing workbench mechanism. Background Art

[0002] Printing refers to the process of transferring information such as text and images onto media such as paper, plastic, and fabric through physical or digital means. Furthermore, surface treatment of the substrate can be carried out during the printing process, and printing can improve the aesthetics of the product during processing.

[0003] In the existing automatic lifting printing workbench mechanism, during the printing process, the substrate is guided by guide rollers, and then the print head is driven by a drive module to approach the moving substrate for printing. However, in actual use, due to the elasticity of the plastic film or fabric and the certain tension of the plastic film or fabric after production, wrinkles and corrugations will form on the surface of the plastic film or fabric due to the tension. These wrinkles and corrugations may affect the printing effect. Therefore, a tension adjustment frame driven by a spring is used during the printing process to adjust the tension of the substrate. After the spring is used for a certain period of time, the resilience will decrease, which may affect the tension adjustment effect and reduce the printing effect. Summary of the Utility Model
