Description

Technical Field

[0001] This utility model relates to the field of printing screen structure technology, and in particular to a printing screen with a mesh protective structure. Background Technology

[0002] The printing screen is the core component of screen printing, responsible for carrying the image and regulating the flow and adhesion of ink. Screen printing uses a photosensitive plate-making method to create a screen printing plate with images and text. Ink passes through the mesh openings of the image areas of the screen, while ink cannot pass through the non-image areas, thus achieving printing. This printing method is suitable for various materials, such as paper, glass, ceramics, and metals, and can support the printing of complex or simple graphic information.

[0003] In the prior art, patent document with publication number (CN217170138U) mentions a printing screen with a mesh protection structure, including a printing base plate. Two inserts are provided on both sides of the printing base plate. The rear end of each insert has a first spring groove A located inside the printing base plate. A first spring A is located inside the first spring groove A. The inserts are connected to the first spring groove A via the first spring A. A support block is provided on one side of the upper surface of the printing base plate. A pressure block is provided below the support block. A first spring groove B is provided on the upper end of the pressure block located on the inner wall of the support block. A first spring B is located inside the first spring groove B. This prior art inserts fix the printing base plate and the printing cover plate, preventing the mesh from slipping during printing, which would lead to unsatisfactory printing results and improve the stability of the device. By fixing the mesh with the pressure block, the printing cover plate can cut off excess mesh, facilitating subsequent processing of the mesh and saving resources.

[0004] However, in the aforementioned existing technologies, the outer side of the mesh fabric is not protected, making it easy to damage during storage or movement. Utility Model Content

[0005] The purpose of this invention is to provide a printing screen with a mesh protective structure, which solves the problem in the prior art that the outer side of the mesh is not protected and is easily damaged during storage or movement.

[0006] To achieve the above objectives, this utility model provides a printing screen with a mesh protective structure, including an outer frame, a mesh, and a protective mechanism. The mesh is fixedly connected to the outer frame and located inside the outer frame. The protective mechanism includes two limiting rods, two sliding blocks, a protective plate, two first springs, and a fixing component. A groove is provided inside the outer frame. The two limiting rods are fixedly connected to the outer frame and are respectively disposed on both sides of the mesh. The protective plate is slidably connected to the outer frame and is located on the surface of the mesh. One end of each of the two sliding blocks is fixedly connected to the protective plate, and the other end of each sliding block is slidably connected to the corresponding limiting rod and is respectively disposed on both sides of the protective plate. The two first springs respectively cover the surface of the corresponding limiting rod and are located on one side of the corresponding sliding block. The fixing component is disposed on one side of the outer frame.

[0007] The protective mechanism further includes a protruding block, which is fixedly connected to the protective plate and located above the protective plate. A slot is provided on one side of the outer frame, which is adapted to the protruding block.

[0008] The fixing assembly includes a rotating rod, a sliding rod, a locking rod, a second spring, and a fixing block. The fixing block is fixedly connected to the protective plate and located on one side of the protective plate. The rotating rod is rotatably connected to the outer frame and located on one side of the outer frame. One end of the sliding rod is slidably connected to the rotating rod, and the other end of the rotating rod is fixedly connected to the locking rod and located on one side of the rotating rod. The locking rod is engaged with the fixing block, and the second spring covers the surface of the sliding rod.

[0009] The fixing component further includes a limiting piece, which is fixedly connected to the sliding rod and located on one side of the sliding rod.

[0010] The fixing component further includes a locking block, which is fixedly connected to the outer frame and located on one side of the outer frame.

[0011] This utility model discloses a printing screen with a mesh fabric protection structure. The outer frame has an internal groove. Two limiting rods are fixedly connected to the outer frame and respectively disposed on both sides of the mesh fabric. A protective plate is slidably connected to the outer frame and located on the surface of the mesh fabric. One end of two sliding blocks is fixedly connected to the protective plate, and the other end of each sliding block is slidably connected to the corresponding limiting rod and respectively disposed on both sides of the protective plate. Two first springs respectively cover the surfaces of the corresponding limiting rods and are located on one side of the corresponding sliding blocks. A fixing assembly is disposed on one side of the outer frame. In use, the screen frame is placed on the surface of the printing material. Ink is applied to the mesh fabric or a pusher block. The pusher block pushes the ink, allowing it to pass through the mesh fabric and be printed onto the material surface. The pusher block is engaged on one side of the protective plate. When the pusher block is pushed, the protective plate moves accordingly. The first spring pushes the sliding block, ensuring the protective plate always moves with the pusher block. When the pusher block leaves the mesh fabric, the first spring pushes the sliding block, causing the protective plate to cover the surface of the mesh fabric, providing constant protection.

[0022] In this specific embodiment, the outer frame 1 has a groove 15 inside. Two limiting rods 3 are fixedly connected to the outer frame 1 and are respectively disposed on both sides of the mesh fabric 2. The protective plate 5 is slidably connected to the outer frame 1 and located on the surface of the mesh fabric 2. One end of each of the two sliding blocks 4 is fixedly connected to the protective plate 5, and the other end of each sliding block 4 is slidably connected to the corresponding limiting rod 3 and is respectively disposed on both sides of the protective plate 5. Two first springs 6 respectively cover the surface of the corresponding limiting rod 3 and are located on one side of the corresponding sliding block 4. The fixing assembly is provided with… The frame is placed on one side of the outer frame 1. In use, the frame is placed on the surface of the printing material, and the ink is applied to the mesh 2 or the push block. The ink is pushed by the push block and passes through the mesh 2 to be printed on the surface of the material. The push block is locked on one side of the protective plate 5. When the push block is pushed, the protective plate 5 moves accordingly. The first spring 6 pushes the sliding block 4 so that the protective plate 5 always moves with the push block. When the push block leaves the mesh 2, the first spring 6 pushes the sliding block 4 so that the protective plate 5 covers the surface of the mesh 2 and provides protection for the mesh 2 at all times.
