[0002] The silk screen printing screen, also known as the screen printing plate, is an indispensable core tool in the silk screen printing process and is widely used in the printing field. The working principle of the silk screen printing screen is based on the process of transferring ink through the mesh to the surface of the substrate. The silk screen is the key part of the screen and is generally woven with materials such as nylon, polyester or stainless steel.

[0003] In the production process of silk screen printing screens, stretching the screen is a key step. Its purpose is to fix the screen evenly and tightly on the screen frame, stretch the screen tightly on the screen frame, ensure that the screen has uniform and appropriate tension, and provide a stable foundation for subsequent plate making and printing, so as to ensure that the ink can evenly penetrate the screen during the subsequent printing process and ensure printing quality.

[0004] However, the existing screen stretching device is not conducive to stretching screens of different sizes. When it is necessary to stretch screens of different sizes, the screen stretching device cannot be conveniently adjusted, which affects the scope of application of the screen stretching device for screen stretching, and is not conducive to stretching screens.

[0005] Therefore, we propose a screen stretching device for screen printing production. Utility Model Content
