Most screen printing machines on the market adopt a fixed structure. These machines are usually heavy. Some screen printing machines are designed to be mobile and equipped with casters. However, due to the lack of effective support devices, the equipment is prone to displacement during the printing process due to the unstable support of the casters, which in turn causes registration deviation problems. Summary of the Invention

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1 to 6This utility model provides a technical solution: a mobile screen printing machine, comprising: a mobile housing 1; a top fixed bracket 2 bolted to the top of the mobile housing 1, with a limiting slide 4 slidably mounted on the top fixed bracket 2; a second cylinder 5 bolted to the limiting slide 4, with an adjusting support plate 6 fixedly connected to the output end of the second cylinder 5; a screen printing frame 27 bolted to the bottom of the limiting slide 4; a printing section disposed on one side of the adjusting support plate 6, with the screen printing frame 27 cooperating with the printing section; and a sliding bracket 14 slidably disposed inside the mobile housing 1. A top sliding platform 10 is provided on the top of the 4, and clamping cylinders 11 are symmetrically installed on the top of the top sliding platform 10; the bottom fixing box 19 is symmetrically installed on the bottom of the movable box 1 by bolts, and an adjusting screw 24 is rotatably provided inside the bottom fixing box 19. An inner sliding plate 25 is installed on the adjusting screw 24 and is slidably connected to the bottom fixing box 19. An adjusting support 22 is symmetrically fixed to the bottom of the inner sliding plate 25 and is slidably connected to the bottom fixing box 19. A moving wheel 23 is installed on the bottom of the adjusting support 22; the support legs 20 are symmetrically fixed to the bottom of the movable box 1.

[0015] It should be noted that in this embodiment, the bottom fixed box 19 is symmetrically installed at the bottom of the movable box 1. Inside, there is a servo motor 26, an adjusting screw 24, an inner sliding plate 25, a second limit slide rod 21, an adjusting support 22, and a moving wheel 23. When the movable device needs to be moved, the servo motor 26 is started, and its output end drives the adjusting screw 24 to rotate. Since the inner sliding plate 25 is connected to the adjusting screw 24, and under the sliding constraint of the second limit slide rod 21, the rotational motion of the adjusting screw 24 is converted into the linear motion of the inner sliding plate 25. The inner sliding plate 25 moves downward, pushing the adjusting support 22 and the moving wheel 23 downward to extend from the bottom fixing box 19, so that the moving wheel 23 contacts the ground and supports the entire equipment. At this time, the equipment can be easily moved across workshops. When the equipment reaches the working position and needs to be fixed, the servo motor 26 rotates in the opposite direction, driving the adjusting screw 24 to rotate in the opposite direction. The inner sliding plate 25 moves upward, pulling the adjusting support 22 and the moving wheel 23 upward to retract, so that the support leg 20 at the bottom of the moving box 1 touches the ground, providing stable support for the equipment and ensuring that the equipment will not shake during the printing process. To resolve the contradiction between the difficulty of handling traditional equipment and the tendency to vibrate during printing, cylinder 3 is activated, driving the limiting slide 4 to rise and fall vertically on the top fixed bracket 2. This quickly adjusts the initial distance between the screen frame 27 installed at the bottom of the limiting slide 4 and the substrate, accommodating substrates of different thicknesses and sizes. Cylinder 5 is installed on the limiting slide 4, with its output end connected to the adjusting support plate 6. Activating cylinder 5 pushes the adjusting support plate 6 to move horizontally, causing the printing section located on one side of the adjusting support plate 6 to move horizontally to the appropriate position. The printing section includes cylinder 3. 7. Support plate 8 and screen squeegee assembly 9. Cylinder 7 is mounted on adjusting support plate 6, with its output end connected to support plate 8. Screen squeegee assembly 9 is located at the bottom of support plate 8. When cylinder 7 is activated, the pressure of screen squeegee assembly 9 on screen frame 27 can be further adjusted. The printing pressure can be precisely controlled according to different printing materials and requirements. During the movement of adjusting support plate 6, limit slide rod 28 plays a precise guiding role, ensuring that adjusting support plate 6 remains stable during horizontal movement and does not tilt or shake, so that screen squeegee assembly 9 is in close contact with screen frame 27. The frame 27 always maintains the correct relative position to ensure uniform pressure distribution and effectively reduce printing defects such as ink smearing and ink penetration. The spring in the screen squeegee assembly 9 is installed at the relevant connection of the squeegee holder and can automatically extend and retract according to the pressure of the screen and the unevenness of the printing surface during the printing process, providing buffering and adaptive adjustment capabilities, so that the pressure between the squeegee blade and the screen is uniform, further improving the printing quality and reducing component damage. The sliding bracket 14 is slidably set inside the movable box 1, and a top sliding table 10 is provided on the top. The top sliding table 10 is symmetrically equipped with clamping cylinders 11.The fourth cylinder 16 is installed inside the movable housing 1 via the inner fixed support plate 15. Its output end is fixedly connected to the sliding bracket 14, which can drive the sliding bracket 14 to move, thereby moving the top sliding table 10 and the clamping cylinder 11 to the appropriate position. The clamping cylinder 11 is activated to firmly clamp the substrate, ensuring that the substrate will not move during the printing process and guaranteeing printing accuracy. The specific architecture and operation logic of the cylinder, battery 18, and servo motor 26 in this application, which are coordinated and controlled by an external controller, are consistent with the existing technology in this field. The servo motor 26 used is equipped with an encoder, which can provide real-time feedback on the speed, position and other information of the servo motor 26. This control method has been maturely applied in many similar industrial scenarios, so it will not be discussed in detail here.

According to different printing materials and requirements, the printing pressure can be precisely controlled to ensure that the ink passes through the screen frame 27 evenly and improve the printing quality. The screen squeegee assembly 9 is mainly composed of a squeegee blade, a squeegee holder, a spring, and a fixing device. The squeegee holder is made of metal and provides a stable mounting base for the squeegee blade.
