However, if two sets of centering positioning components are required to work together and the length of the plate changes, it is difficult for the existing plate roller conveyor to adjust the position of the centering positioning component. Therefore, an improved technology is urgently needed to solve this problem in the existing technology. Summary of the Invention

The upper surface of the frame 4 is also provided with several support plates 2 and several centering positioning mechanisms 3. The two ends of the support plates 2 are provided with first bending plates 12. The bottom of the first bending plates 12 is connected to the upper surface of the frame 4 by bolts to realize the installation and disassembly of the support plates 2. Several bearing seats 7 are provided on one side of the bottom of the frame 4. The inner side of each bearing seat 7 is provided with a first double-row sprocket 8 through a shaft. The outer end of one of the bearing seats 7 is provided with a second reduction motor 9.

Adjacent first double-row sprockets 8 are linked with each other through a chain. Adjacent second double-row sprockets 10 are linked with each other through a chain. The second reduction motor 9 drives the corresponding first double-row sprocket 8 to rotate. The first double-row sprocket 8 acts as the driving sprocket. With the transmission of the chain, it drives each second double-row sprocket 10 to rotate, thereby driving all the support rollers 1 to rotate synchronously. A baffle 13 is provided on the upper surface of the frame 4 and on one side of the second double-row sprocket 10 to prevent personnel from accidentally touching the second double-row sprocket 10 and the chain, thereby improving safety. like Figure 5As shown, the centering positioning mechanism 3 includes a mounting plate 301, guide rails 302, a left slide 303, a right slide 304, positioning wheels 305, a support plate 306, a bidirectional threaded screw 307, and a first reduction motor 308. The mounting plate 301 is connected to the frame 4 on both sides by bolts. Two guide rails 302 are arranged along the length of the upper surface of the mounting plate 301. A bidirectional threaded screw 307 is arranged along the length of the upper surface of the mounting plate 301 between the two guide rails 302 via a screw seat. The first reduction motor 308 is located at one end of the mounting plate 301. The output shaft of the first reduction motor 308 is connected to one end of the bidirectional threaded screw 307 via a coupling. The left slide 303 and the right slide 304 are slidably connected to the two guide rails 302 via sliders 309. Positioning wheels 305 are arranged on the upper surfaces of both the left slide 303 and the right slide 304 via columns 310. The lead screw 307 has symmetrical threads at both ends. The left slide 303 is threaded to one end of the double-threaded lead screw 307 through the lead screw nut pair 311, and the right slide 304 is threaded to the other end of the double-threaded lead screw 307 through the lead screw nut pair 311. A support plate 306 is provided above the mounting plate 301. The support plate 306 has second bending plates 313 on both sides. The second bending plates 313 are connected to the mounting plate 301 by bolts. The height of the support plate 306 is the same as the height of the support plate 2 to realize the installation and disassembly of the support plate 306 and to prevent the metal sheet from falling off. The support plate 306 has grooves 312 at both ends. The positioning wheels 305 on the upper surface of the left slide 303 and the right slide 304 are respectively set in the grooves 312 at both ends of the support plate 306. The double-threaded lead screw 307 can also be formed by splicing two lead screws with opposite threads through a coupling.

[0017] Installation method and operating principle: First, assemble the centering positioning mechanism 3. Connect the left slide 303 and the right slide 304 to the two guide rails 302 through the slider 309. At the same time, connect the left slide 303 and the right slide 304 to the threaded ends of the bidirectional threaded screw 307 through the screw nut pair 311. Then, install the two ends of the bidirectional threaded screw 307 on the mounting plate 301 through the screw seat. At the same time, install the guide rails 302 on the mounting plate 301 with bolts. Positioning wheels 305 are mounted on the tops of the left slide 303 and the right slide 304 via columns 310. The first reduction motor 308 is mounted on one end of the mounting plate 301, and the output shaft of the first reduction motor 308 is connected to one end of the double-threaded screw 307 via a coupling. Finally, the support plate 306 is bolted onto the top of the mounting plate 301. At this point, the two positioning wheels 305 are located in the grooves 312 at both ends of the support plate 306, completing the assembly of the centering positioning mechanism 3, which is a modular structure. Subsequently, the centering positioning mechanism 3 can be mounted on the corresponding position of the frame 4 via the mounting plate 301 and bolts according to the actual product length. Then, the support roller 1 is mounted on the frame 4 via the support 6 and bolts, and the support plate 2 is mounted on the frame 4 via the first bending plate 12 and bolts. When installing the support roller 1, the chain can be directly connected to the second double-row sprocket 10 at the end of the support roller 1. Finally, the bearing 7 with the first double-row sprocket 8 is installed on the lower surface of the frame 4, ensuring the first double-row sprocket 8 and the second double-row sprocket 10 are on the same side. The chain is then used to connect adjacent first double-row sprockets 8. Finally, the first double-row sprockets 8 at both ends are connected to the corresponding second double-row sprocket 10 via chains, completing the installation. It should be noted that if two centering positioning mechanisms 3 are needed to position the plate, they should be installed close together to clamp the plate. After positioning, the two positioning wheels 305 are separated. In use, the trapezoidal metal plate is placed on the conveyor, and the second reduction motor 9 is started. The second reduction motor 9 drives the corresponding first double-row sprocket 8 to rotate. Through the cooperation of multiple chains with the first double-row sprocket 8 and the second double-row sprocket 10, the support roller 1 rotates. The first reduction motor 308 drives the bidirectional threaded screw 307 to rotate, causing the left slide 303 and the right slide 304 to move closer and further apart, thereby achieving the centering and positioning of the trapezoidal plate. Figure 6 As shown. This utility model has a reasonable structure. Through the left slide 303 and right slide 304 of the centering positioning mechanism 3, the distance between the two positioning wheels 305 can be adjusted, which can realize the centering positioning of the trapezoidal plate. Furthermore, the centering positioning mechanism 3 adopts a modular structure, and the whole is installed on the mounting plate 301. The mounting plate 301 is connected to the frame 4 by bolts, which facilitates installation and disassembly. This makes it easy to adjust the position of the centering positioning mechanism 3 according to the length of the metal plate or workpiece, greatly improving flexibility.
