[0029] like Figures 1 to 5As shown, an embodiment of this utility model provides a polyurethane-edged metal screen plate with replaceable screen bars, including a screen plate frame 1. The screen plate frame 1 has two mounting cavities 101 inside. Mounting members 2 are provided at each of the four corners of the screen plate frame 1. Each mounting cavity 101 contains a screen bar body 3. A connecting assembly is also provided for quick assembly and disassembly between the screen bar body 3 and the mounting cavity 101. The connecting assembly is connected to the mounting cavity 101 and includes connecting seats 4 fixedly connected to the four corners of the inner wall of the mounting cavity 101. A central column is fixedly connected to the top of each connecting seat 4. 5. A ring of limiting members 6 is arranged on the outer surface of the central column 5. The limiting member 6 includes an arc-shaped fitting part 601 fixedly connected to the connecting seat 4. The top of the arc-shaped fitting part 601 is provided with a connecting part 602. One side of the connecting part 602 is fixedly connected to the outer surface of the central column 5 through a reset part 604. The top of the connecting part 602 is provided with an arc-shaped guide part 603. The inner wall of the mounting cavity 101 fits against the outside of the screen bar body 3. The four corners of the bottom of the screen bar body 3 are provided with connecting holes adapted to the connecting components. The two sides of the inner wall of the mounting cavity 101 are fixedly connected with abutment members 7. The bottom of component 7 fits against the top of the screen bar body 3. The shape of component 7 is a flat "C". A clearance groove 701 is provided on the opposite surface of the mounting cavity 101 and the contact component 7. When it is necessary to install the screen bar body 3, first align the bottom of the screen bar body 3 with the opening of the mounting cavity 101, and align the four corners of the screen bar body 3 with the center post 5 on the connecting seat 4. Then, push the screen bar body 3 down along the center post 5 until the bottom of the screen bar body 3 is completely inserted into the mounting cavity 101, and the connecting hole of the screen bar body 3 is aligned with the arc-shaped guide part 603 of the limiting component 6. During this process, the arc... The guide part 603 plays a guiding role, allowing the screen bar body 3 to slide smoothly along the central column 5 and avoiding excessive friction with the inner wall of the mounting cavity 101. When the screen bar body 3 is fully inserted into the mounting cavity 101, the connecting part 602 of the limiting member 6 will automatically move towards the connecting hole of the screen bar body 3 under the action of the reset part 604 until the connecting part 602 is fully engaged with the connecting hole of the screen bar body 3. At this time, the arc-shaped fitting part 601 of the limiting member 6 will fit tightly against the outside of the screen bar body 3, thereby ensuring the stable fixation of the screen bar body 3 in the mounting cavity 101.

[0030] After the screen bar body 3 is completely fixed, the bottom of the contact part 7 will fit tightly against the top of the screen bar body 3, further increasing the stability of the screen bar body 3. At the same time, the contact part 7 is flat "C" shaped, which can adapt well to the top shape of the screen bar body 3 and prevent the screen bar body 3 from shifting during installation.

[0031] When it is necessary to disassemble the screen bar body 3, simply push the screen bar body 3 upwards to disengage the connecting part 602 from the connecting hole of the screen bar body 3, and the disassembly of the screen bar body 3 can be easily completed. By setting the connecting component, the quick assembly and disassembly between the screen bar body 3 and the mounting cavity 101 are realized, which greatly improves the maintainability and flexibility of the screen plate. The design of the limiting part 6 ensures that the screen bar body 3 is firmly fixed in the mounting cavity 101, avoiding the problem of displacement or falling off of the screen bar body 3 during operation. The design of the connecting component and the abutment part 7 makes the installation process of the screen bar body 3 simpler and more intuitive, reducing the labor intensity of the workers.

[0032] Since the main body 3 of the screen bar can be easily replaced and adjusted, the most suitable screen bar size and screen hole arrangement can be selected according to actual needs, thereby improving the screening accuracy and efficiency.

[0033] The screen frame 1 is wrapped with polyurethane, which enhances the wear resistance of the screen edge and extends the service life of the screen. Since the screen bar body 3 can be replaced individually without replacing the entire screen, the maintenance cost is greatly reduced.

[0034] The working principle provided by this utility model is as follows: the screen bar body 3 is connected to the connecting assembly inside the mounting cavity 101 through the connecting hole at its bottom. The connecting assembly includes connecting seats 4 fixedly connected to the four corners of the inner wall of the mounting cavity 101. A central column 5 is fixedly connected to the top of each connecting seat 4. A ring of limiting members 6 is arranged on the outer surface of the central column 5. The limiting member 6 includes an arc-shaped fitting part 601, a connecting part 602, a reset part 604, and an arc-shaped guide part 603. When installing the screen bar body 3, firstly, align the bottom of the screen bar body 3 with the opening of the mounting cavity 101, and align the four corners of the screen bar body 3 with the central column 5 on the connecting seat 4. Then, push the screen bar body 3 downward along the central column 5 until the connecting hole of the screen bar body 3 is aligned with the arc-shaped guide part 603 of the limiting member 6. The arc-shaped guide part 603 plays a guiding role. The screen bar body 3 can slide smoothly along the central column 5, avoiding excessive friction with the inner wall of the mounting cavity 101. After the screen bar body 3 is fully inserted into the mounting cavity 101, the connecting part 602 of the limiting member 6 moves automatically towards the connecting hole of the screen bar body 3 under the action of the reset part 604 until the connecting part 602 is fully engaged with the connecting hole of the screen bar body 3. At this time, the arc-shaped fitting part 601 of the limiting member 6 fits tightly with the outside of the screen bar body 3, ensuring that the screen bar body 3 is firmly fixed in the mounting cavity 101. When it is necessary to disassemble the screen bar body 3, simply push the screen bar body 3 upward with force so that the connecting part 602 comes out of the connecting hole of the screen bar body 3. Since the design of the limiting member 6 is elastic, the connecting part 602 can easily pop out of the connecting hole, thereby realizing the quick disassembly of the screen bar body 3.
