[0003] 1. Difficulty in angle adjustment: After the screen printing plate is installed, it cannot be finely adjusted according to the alignment requirements of the screen printing surface.

[0004] 2. Insufficient stability: During the printing process, the screen printing plate is prone to displacement or skew, resulting in pattern misalignment and reprinting.

[0005] 3. Poor compatibility: The fixed structure is only compatible with screen printing boards of a specific size, and the entire board needs to be disassembled and adjusted when replacing it.

[0006] To solve the above problems, there is an urgent need for a screen printing plate fixing structure that supports quick assembly and disassembly, fine angle adjustment, and strong stability. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a rapid positioning mechanism for a running table printing machine, which solves the defects of traditional technologies and enables flexible angle micro-adjustment of the screen printing plate connector; modular and rapid installation and disassembly of the screen printing plate; and scalability compatible with screen printing plates of different sizes.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A rapid positioning mechanism for a running table printing machine includes a receiving seat, a balance block, and a screen printing plate connector. A support rod is fixedly connected to the middle of the balance block, and the other end of the support rod is fixedly connected to the receiving seat. Balance rods are fixedly connected to both ends of the balance block, and the other end of the balance rod passes through the receiving seat and is fixedly connected to an adapter. A corner block is rotatably connected to the adapter, and the screen printing plate connector is fixedly connected to the front side of the corner block. A fixing plate and two pressure blocks are provided on the upper part of the screen printing plate connector, and the two pressure blocks together press the fixing plate to fix it on the screen printing plate connector.

[0010] Furthermore, the screen printing plate connector has an inner cavity, in which a transverse slide rail, a slider slidably connected to the transverse slide rail, and a mounting block fixed on the slider are provided; the two pressure blocks are fixedly connected to the upper surface of the mounting block.

[0011] Furthermore, the mounting block has a protrusion in the middle of its upper surface, which is square or round; the fixing plate has positioning holes that are adapted to the protrusion.

[0012] Furthermore, one end of the mounting block is provided with a stop block; one end of the screen printing plate connector is provided with a stop block and a top rod screwed to the stop block, and the front end of the top rod abuts against the stop block.

[0013] Furthermore, the corner block is provided with a clearance groove, and the adapter is inserted into the clearance groove; the adapter and the corner block are rotatably connected by a rotating shaft passing through both.

Detailed Implementation

[0025] 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.

[0026] See Figure 1-4 As shown, this embodiment provides a rapid positioning mechanism for a treadmill printing machine, including a receiving seat 1, a balance block 2, and a screen printing plate connector 3. A support rod 4 is fixedly connected to the middle of the balance block 2, and the other end of the support rod 4 is fixedly connected to the receiving seat 1. Balance rods 5 are fixedly connected to both ends of the balance block 2, and the other end of the balance rod 5 passes through the receiving seat 1 and is fixedly connected to an adapter 6. A corner block 7 is rotatably connected to the adapter 6, and the screen printing plate connector 3 is fixedly connected to the front side of the corner block 7. A fixing plate 8 and two pressure blocks 9 are provided on the upper part of the screen printing plate connector 3, and the two pressure blocks 9 press the fixing plate 8 onto the screen printing plate connector 3. Through the rotating connection design of the adapter 6 and the corner block 7, the screen printing plate connector 3 can be flexibly rotated and adjusted, which can adapt to the fine adjustment needs of different screen printing surfaces and solve the defect of traditional fixed structures that cannot adjust the angle. The modular design of the pressure block 9 pressing the fixing plate 8 allows the pressure block 9 to directly press the fixing plate 8, forming a mechanical locking mechanism. Simultaneously, multi-point pressing ensures a tight fit between the fixing plate 8 and the screen printing plate connector 3, improving stability and preventing vibration displacement during printing. The balance block 2, through the support rod 4 and balance rod 5, forms a symmetrical support structure, distributing the force and preventing the screen printing plate connector 3 from tilting during adjustment, thus ensuring printing accuracy.

[0027] The screen printing plate connector 3 has an internal cavity containing a transverse slide rail 10, a slider 11 slidably connected to the transverse slide rail 10, and a mounting block 12 fixed to the slider 11. Two pressure blocks 9 are fixedly connected to the upper surface of the mounting block 12, specifically locked to the mounting block 12 by screws, with a fixing plate 8 pressed against their other side. The internal cavity integrates the sliding mechanism of the transverse slide rail 10 and the slider 11, allowing the mounting block 12 to move laterally within the internal cavity, simplifying the installation or removal process of the mounting block and improving operational efficiency. Through the sliding and replaceable design of the mounting block 12, different types of mounting blocks can be replaced according to the size of the screen printing plate, achieving size compatibility of the screen printing plate 18 and enhancing structural flexibility.

[0028] The upper surface of the mounting block 12 has a protrusion 13 in the middle, which is square or round; the fixing plate 8 has positioning holes that fit the protrusion 13. The cooperation between the protrusion 13 and the positioning holes forms a physical positioning mechanism, which provides guidance and alignment when installing the fixing plate 8, ensuring that the fixing plate 8 is accurately installed on the mounting block 12 and preventing minor displacement during the printing process.

[0029] One end of the mounting block 12 is provided with a stop block 14; one end of the screen printing plate connector 3 is provided with a stop block 15 and a push rod 16 screwed onto the stop block 15, with the front end of the push rod 16 abutting against the stop block 14. The abutment between the push rod 16 and the stop block 14 constitutes a mechanical locking mechanism. When the push rod is screwed in, it pushes the stop block, and after the mounting block 12 moves laterally, it is firmly locked in the designated position, preventing the slider 11 from accidentally sliding during printing vibration and ensuring the stability of the mounting block 12 and the fixing plate 8. The screw-on push rod 16 design provides manually adjustable locking force, allowing for quick locking and unlocking without additional tools, improving maintenance efficiency.

[0030] The corner block 7 is provided with a clearance groove, and the adapter 6 passes through the clearance groove; the adapter 6 and the corner block 7 are rotatably connected by a rotating shaft 17 passing through them. The clearance groove provides room for the adapter 6 to move, and combined with the rotatable connection of the rotating shaft 17, it ensures that the angle adjustment process is smooth and without interference.

[0031] The fixing plate 8 is provided with a locking position 19 for connecting the screen printing plate 18, and the locking position 19 is equipped with a locking screw. The locking position 19 and the locking screw provide a high-strength mechanical fixation to prevent the screen printing plate from shifting. The locking position 19 provides a dedicated connection point for the screen printing plate 18, and together with the mechanical fastening of the locking screw, a high-rigidity fixation is formed, effectively preventing the screen printing plate from shifting or loosening during high-speed printing, ensuring the accuracy and consistency of the printed pattern.

[0032] The rear side of the corner block 7 is connected to an external transmission mechanism, which drives the screen printing plate connector 3 to rotate and adjust the angle. By driving the corner block 7 through an external transmission mechanism, such as a motor or cylinder, the automatic rotation and fine adjustment of the screen printing plate connector 3 can be achieved, reducing manual intervention, improving the accuracy and efficiency of angle adjustment, and adapting to the needs of continuous production.

[0033] In use, the two sets of rapid positioning mechanisms of the printing press of the present invention are movably or fixedly connected to the crossbeam 20 through the bearing seat. The two sets of rapid positioning mechanisms of the printing press together fix a screen printing plate 18. The external transmission mechanism pushes the corner block 7 to rotate around the rotating shaft 17, which drives the screen printing plate connecting body 3 to rotate synchronously, so as to realize the fine adjustment of the screen printing surface angle, perfectly adapt to the needs of different screen printing surfaces, and improve the versatility of the printing machine.
