Description

Technical Field

[0001] This utility model relates to the field of screen printing technology, specifically a low-cost mechanism for receiving screen printing equipment components or devices. Background Technology

[0002] Screen printing equipment is a specialized machine used to achieve the printing process. Its principle is to use a squeegee to transfer ink from the image area on a pre-made screen to the substrate. The equipment that achieves this purpose is called screen printing equipment. Its core components include the squeegee arm assembly and the screen arm assembly. The two need to work together to achieve the screen printing process: the screen arm assembly fixes the screen through a clamping mechanism, while the squeegee arm assembly drives the squeegee to scrape the ink on the screen surface at a specific angle and pressure, so that it penetrates evenly into the substrate. The spatial relative position and dynamic balance between the two directly affect the printing quality / effect.

[0003] However, in existing equipment, the squeegee arm and screen arm are usually designed as a set, and their receiving mechanism has functional limitations. On the one hand, the traditional structure can only adapt to components of specific specifications, requiring the independent development of dedicated receiving bodies for different configurations, increasing R&D costs and maintenance complexity. On the other hand, the existing mechanism lacks dynamic adjustment capabilities, making it impossible to quickly release the screen for cleaning or replacement through opening actions, and also difficult to accurately maintain the rigid coupling relationship between the squeegee arm and screen arm through tightening actions, affecting printing stability. In addition, due to the space constraints of single-end swing arm equipment, traditional swing mechanisms cannot achieve high torque output in a compact layout, and the low standardization of power input interfaces results in insufficient compatibility with diverse frame designs, irregularly shaped substrates, and external drive units, restricting the expansion of equipment application scenarios.

The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No feature of the application is considered critical unless it is expressly stated in the claims.
