The elastic block 7 can further buffer the impact of external vibration on the printing screen body 1 during installation and printing, protect the printing screen body 1, extend its service life, and at the same time ensure that the printing screen body 1 always remains stable, thereby improving the printing effect.

[0034] Preferred, such as Figure 4 As shown, a slider 8 is installed on the outer side of the support plate 44, an electric slide rail 9 is installed on the outer side of the slider 8, a connecting plate 10 is installed on the outer side of the electric slide rail 9, and the connecting plate 10 is installed at the output end of the hydraulic cylinder 45.

[0035] As a technical optimization of this utility model, by setting up a slider 8, an electric slide rail 9 and a connecting plate 10, the electric slide rail 9 can precisely control the movement of the slider 8, thereby driving the support plate 44 and the connecting frame 2 to move, so as to realize the fine adjustment of the position according to the actual situation of the printing screen version 1. This makes the printing screen version 1 more flexible in adjusting its position during installation, adapting to the installation requirements of different printing equipment, and improving the flexibility and adaptability of installation.

[0036] In addition, such as Figure 2 As shown, movable grooves 11 are provided on both sides of the bottom outer side of the inner wall of the connecting groove 41. Movable blocks 12 are slidably connected inside the movable grooves 11, and the top of the movable blocks 12 is installed with the bottom of the positioning plate 51.

[0037] As a technical optimization of this utility model, by setting the movable groove 11 and the movable block 12, the movable block 12 slides in the movable groove 11, providing a stable guide for the movement of the positioning plate 51, ensuring that the positioning plate 51 will not shift when clamping the connecting frame 2, further ensuring the firmness and accuracy of the printing screen version 1 after installation, and avoiding positional changes of the printing screen version 1 during use.

[0038] It is worth noting that, such as Figure 3 As shown, a sliding groove 13 is provided on the outer side of the movable column 52, and a movable block 14 is slidably connected inside the sliding groove 13. The movable block 14 is installed inside the connecting groove 41.

[0039] As a technical optimization of this utility model, by setting the slide groove 13 and the moving block 14, auxiliary support and guidance are provided for the movement of the movable column 52, reducing the shaking of the movable column 52 during the movement process, making the movement of the movable column 52 pushing the positioning plate 51 more stable, and at the same time avoiding the situation where the movable column 52 follows the rotation of the movable rod 53, thus enhancing the positioning stability during use.

[0040] Furthermore, such as Figure 4 As shown, an electric push rod 15 is installed at the bottom inside the slider 8. A connecting strip 16 is installed at the output end of the electric push rod 15. A connecting block 21 is installed inside the connecting strip 16. Several connecting blocks 21 are provided, and the several connecting blocks 21 are arranged at equal distances.

[0041] As a technical optimization of this utility model, by setting an electric push rod 15, a connecting strip 16, and a connecting block 21, the electric push rod 15 can adjust the position of the connecting block 21 according to actual needs, providing additional support for the printing screen body 1. During the printing process, the connecting block 21 can share part of the weight of the printing screen body 1 and the connecting frame 2, reduce the burden on the support plate 44 and the positioning plate 51, prevent the printing screen body 1 from deforming due to gravity or printing pressure, and improve the durability and printing quality of the printing screen body 1.

[0042] Preferred, such as Figure 4 As shown, a protective box 17 is installed on the inner side of the connecting plate 10, and the electric slide rail 9 is located inside the protective box 17. A moving groove 18 is provided on the inner side of the protective box 17.

[0043] As a technical optimization of this utility model, by setting up a protective box 17 and a moving groove 18, the protective box 17 can protect the electric slide rail 9, prevent dust, ink and other impurities from entering the electric slide rail 9 and affecting its normal operation, and extend the service life of the electric slide rail 9. The moving groove 18 provides space for the movement of the slider 8, and at the same time plays a certain limiting role in the movement of the slider 8, ensuring that the slider 8 moves within the specified range, and improving the safety and stability of the equipment operation.

[0044] In addition, such as Figure 4 As shown, a bellows cover 19 is installed on the outer side of the inner wall of the moving groove 18, the inner side of the bellows cover 19 is installed on the outer side of the slider 8, and a protective column 20 is installed on the outer side of the electric push rod 15.

[0045] As a technical optimization of this utility model, by setting up the bellows protective cover 19 and the protective column 20, the bellows protective cover 19 can further protect the electric slide rail 9 and the slider 8, prevent impurities from entering, and also play a certain role in dustproofing and waterproofing. The protective column 20 can protect the electric push rod 15, prevent the electric push rod 15 from being damaged by external impact, ensure the normal operation of the electric push rod 15, and thus ensure the stable operation of the entire combined printing screen.

[0046] The working principle and usage process of this utility model are as follows: First, the mounting plate 3 is installed on the printing equipment. When installing the printing screen body 1, the connecting frame 2 that drives the printing screen body 1 is moved into the inside of the connecting groove 41. The limiting blocks 43 at the four corners of the bottom of the connecting frame 2 are aligned with the limiting grooves 42 in the connecting groove 41 to achieve initial positioning, so that the connecting frame 2 can quickly find the correct position. Then, by starting the hydraulic cylinder 45, the hydraulic cylinder 45 pushes the connecting plate 10. The connecting plate 10 drives the electric slide rail 9, the slider 8 and the support plate 44 connected to it to move. The movement of the support plate 44 can limit and support the outside of the connecting frame 2, improving the accuracy of installation.

[0047] After initial positioning is completed, the motor 55 is started. The output end of the motor 55 drives the reducer 54 to rotate. The reducer 54 drives the movable rod 53 to rotate. Since the movable rod 53 is threadedly connected to the movable column 52, the movable column 52 will move under the drive of the movable rod 53, thereby pushing the positioning plate 51 to fix the connecting frame 2, completing the installation of the printing screen body 1, ensuring that the printing screen will not shake or shift during the printing process, and achieving the effect of quick installation.

[0048] During the printing process, if it is necessary to fine-tune the position of the printing screen version 1, the movement of the slider 8 can be precisely controlled by controlling the electric slide rail 9, thereby driving the support plate 44 and the connecting frame 2 to move, so as to achieve fine-tuning of the position to adapt to different printing needs. During printing, the electric push rod 15 can adjust the position of the connecting block 21 according to actual needs, providing additional support for the printing screen version 1 and the connecting frame 2, sharing some of their weight, reducing the burden on the support plate 44 and the positioning plate 51, and preventing the printing screen version 1 from deforming due to gravity or printing pressure.

[0049] Meanwhile, the buffer plate 6 alleviates the direct impact of the positioning plate 51 on the connecting frame 2, and the elastic block 7 buffers the impact of external vibrations on the printing screen version 1, protects the printing screen version 1, extends its service life, and ensures that the printing screen version 1 always remains stable.

[0050] When disassembly is required, the motor 55 is started in reverse. The motor 55 drives the reducer 54 to reverse the movable rod 53. Under the action of the thread, the movable column 52 moves away from the connecting frame 2. The positioning plate 51 separates from the connecting frame 2, releasing the clamping state of the connecting frame 2. By starting the hydraulic cylinder 45, the hydraulic cylinder 45 drives the support plate 44, electric slide rail 9, slider 8, etc. to move away from the mounting plate 3, so that the limiting blocks 43 at the four corners of the bottom of the connecting frame 2 disengage from the limiting grooves 42 in the connecting groove 41. In this way, the connecting frame 2 and the printing screen body 1 installed inside it can be removed from the mounting plate 3, completing the disassembly. This achieves the effect of convenient installation and disassembly maintenance, and enhances the use effect of the printing screen.

[0051] In summary, this modular printing screen, through the use of the movable limiting component 4 and the clamping positioning component 5, conveniently installs the printing screen body 1 and the connecting frame 2 on the top of the mounting plate 3. This solves the problem that the installation process of existing printing screens with printing equipment is cumbersome and difficult to achieve quick installation. Whenever the screen needs to be replaced or routine disassembly and maintenance is required, the staff has to spend a lot of time and energy on the installation process, which not only affects work efficiency but also prolongs equipment downtime and reduces the effectiveness of the printing screen.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
