They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figures 1 to 4As shown, this utility model discloses a printing plate for surface treatment of lightbox fabric, including a frame 1. Connecting seats 5 are symmetrically arranged on both sides of the frame 1. Connecting slots 51, adapted to the height of the screen printing plate 2, are opened on the connecting seats 5. Both ends of the screen printing plate 2 can slide horizontally into the connecting slots 51. A doctor blade 3 and a return blade 4 are provided above the screen printing plate 2. Both are connected to the frame 1 via a slide rail and can slide horizontally under the drive of a driving device (such as a cylinder or motor) to perform doctoring and return operations on the surface of the screen printing plate 2, respectively. The driving device is an existing structure and will not be described in detail. Furthermore, the doctor blade 3 and the return blade 4 are respectively connected to a cylinder or hydraulic cylinder for lifting and lowering. An ink storage area is provided on the side of the screen printing plate 2 near the doctor blade 3 and the return blade 4 for storing the ink to be printed.

[0022] To enable quick assembly and disassembly of the screen printing plate 2, a first connecting hole 52 communicating with the connecting groove 51 is provided on the connecting seat 5, and second connecting holes are provided at both ends of the screen printing plate 2. When the screen printing plate 2 is fully slid into the connecting groove 51, the first connecting hole 52 and the second connecting hole are aligned. A pin 7 is installed on the connecting seat 5, and the pin 7 is inserted into the first connecting hole 52 and the second connecting hole to fix the screen printing plate 2 by telescoping. A sleeve 6 is fitted around the outer periphery of the pin 7, and a cavity 61 is provided inside the sleeve 6. One end of the pin 7 extends into the cavity 61 as a connecting end and is connected to the spring 8 inside the cavity 61 through the flange 71, while the other end of the pin 7 serves as an extension end. One end of the spring 8 is fixed to the inner wall of the cavity 61, and the other end is fixed to the flange 71, so that the pin 7 is in a naturally extended state when no external force is applied, ensuring locking stability.

[0023] In this embodiment, a guide ramp 21 is also provided at the end of the screen printing plate 2, and the height of the guide ramp 21 gradually decreases along the sliding direction of the screen printing plate 2. In addition, the extension end of the pin 7 is designed to be arc-shaped to reduce the frictional resistance generated when in contact with the screen printing plate 2, thereby facilitating lifting. When the screen printing plate 2 slides into the connecting groove 51, the guide ramp 21 contacts the arc-shaped extension end of the pin 7, and the pin 7 is lifted upward by the ramp until the screen printing plate 2 is in place. Then, the pin 7 automatically inserts into the corresponding second connecting hole under the elastic force of the spring 8, completing a quick lock. In this way, there is no need to manually lift the pin 7 when installing the screen printing plate 2, thereby improving the convenience of installation.

[0024] Furthermore, to improve the efficiency of disengaging the pins 7 from the first and second connecting holes when removing the screen printing plate 2, a connecting frame 9 is provided above the connecting seat 5. The connecting frame 9 has a sleeve hole that fits around the outer periphery of the sleeve rod 6. The connecting frame 9 can be manually driven to move vertically, thereby causing all the pins 7 to move upwards synchronously, allowing the pins 7 to be pulled out from the first and second connecting holes, achieving rapid unlocking and disassembly of the screen printing plate 2. A guide seat 10 is fixed to one end of the connecting seat 5, and the guide seat 10 is connected to the frame 1. A guide groove 101 is provided on the guide seat 10, and the guide end 91 of the connecting frame 9 extends into the guide groove 101 and can slide within it, ensuring a stable vertical movement trajectory of the connecting frame 9.

[0025] In this embodiment, a through threaded hole is provided on the guide end 91, and a locking rod 11 is installed in the threaded hole. The locking rod 11 and the threaded hole form a threaded engagement. When the connecting frame 9 moves to the predetermined position (such as when the pin 7 is fully pulled out), the locking rod 11 is rotated so that its end presses against the inner wall of the guide groove 101. The position of the connecting frame 9 is fixed by friction, preventing the pin 7 from falling accidentally, thereby facilitating the operator to replace or adjust the screen printing plate 2.

[0026] The actual usage process is as follows: When installing the screen printing plate 2, push both ends of it horizontally into the connecting groove 51 of the connecting seat 5. The guide slope 21 contacts the extended end of the pin 7, forcing the pin 7 to rise upwards until the screen printing plate 2 is fully in place. Then, the pin 7 is inserted into the second connecting hole under the action of the spring 8, completing the locking. When disassembling, pull the connecting bracket 9 upwards, causing all the pins 7 to be pulled out simultaneously. After rotating the locking rod 11 to fix the position of the connecting bracket 9, the screen printing plate 2 can be pulled out.

[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
