It is used in stone processing production lines.
[0003] Granite slabs are hard but brittle. When conveyed by an automatic loading and unloading machine, the surface can be scratched due to friction and collision between the frame and the slab, affecting the product's appearance and value.

The inner side of the rotating component 49 is provided with a support component 48, which includes two rotating shafts 481. The left and right sides of the outer walls of the two rotating shafts 481 are respectively fixedly connected to the inner side of the multiple movable bearings 491. The outer walls of the two rotating shafts 481 are all fixedly connected with wheel frames 482. Specifically, when the drive mechanism 4 is working, the two drive seats 41 are fixed to the bottom left and right sides of the traveling beam 31 by bolts 42 on the front and rear sides. The inner drive bearing 44 supports the rotation of the rotating shaft 45. The protective sleeve 43 protects the drive bearing 44. Through the cooperation between the drive seat 41 and the rotating shaft 45, the traveling beam 31 is provided with the power to move. The gear 461 on the outer wall of the rotating shaft 45 rotates with the rotating shaft 45 and meshes with the traveling rack 462 at the bottom of the crossbeam 2, driving the traveling beam 31 to move along the length of the crossbeam 2. Through the cooperation of the gear 461 and the traveling rack 462, the displacement adjustment of the traveling beam 31 is realized. Multiple fixing rings 471 of the mounting component 47 are fixed to the four corners of the bottom of the traveling beam 31 by the second bolt 472 at the top. The inner movable bearing 491 provides rotational support for the support component 48. The second protective sleeve 492 protects the movable bearing 491. The cooperation between the fixing rings 471 and the movable bearing 491 ensures the stable installation of the support component 48. The two rotating shafts 481 of the support component 48 rotate with the moving bearing 491, and the wheel frame 482 on the outer wall contacts the crossbeam 2, which plays an auxiliary support role when the traveling beam 31 moves, reducing the swaying during the movement. Through the cooperation of the rotating shaft 481 and the wheel frame 482, the stability of the traveling beam 31 is improved. Throughout the driving process, the drive bearing 44 reduces the friction between the rotating shaft 45 and the drive seat 41, ensuring that the rotating shaft 45 rotates smoothly. The moving bearing 491 reduces the friction between the rotating shaft 481 and the fixed ring 471, ensuring that the support assembly 48 operates flexibly and works together to make the traveling beam 31 move stably. The drive seat 41 provides the moving power through the cooperation of the rotating shaft 45, the gear 461 and the traveling rack 462 achieve displacement adjustment through the cooperation of the fixed ring 471 and the moving bearing 491, the support component 48 is stably installed through the cooperation of the rotating shaft 481 and the wheel frame 482, and the moving stability is enhanced through the cooperation of the rotating shaft 481 and the wheel frame 482, together completing the drive control of the traveling beam 31.
[0020] Working principle: The traveling beam 31 of the pressure roller mechanism 3 is placed on the top of the crossbeam 2. The two fixed seats 32 on the front and rear sides of the top of the traveling beam 31 are fixed to the crossbeam 2 by the fixed screws 33 on the top, so as to prevent the traveling beam 31 from shifting position during movement, thereby achieving a stable installation of the traveling beam 31. The axles 34 at the front and rear ends of the inner side of the traveling beam 31 begin to rotate. When the axles 34 rotate, they drive the extrusion rollers 35 connected to the outer wall support bearings 36 to rotate synchronously. During the rotation, the extrusion rollers 35 contact the crossbeam 2 and apply pressure, thereby achieving fixation at the top of the crossbeam 2. Multiple nuts 381 of the fixing component 38 are threaded to the left and right ends of the axles 34. The gaskets 382 between adjacent nuts 381 enhance the sealing of the connection, preventing the nuts 381 from loosening when the axles 34 rotate, ensuring that the axles 34 and the extrusion rollers 35 are firmly connected. Multiple rubber rings 37 on the left and right sides of the outer wall of the extrusion rollers 35 contact the material, which increases the lateral support force during extrusion and buffers the impact force during rolling, avoiding damage to the surface of the crossbeam 2 and improving the stability and safety of the support process. Two drive seats 41 are fixed to the bottom left and right sides of the traveling beam 31 by bolts 42 on the front and rear sides. The drive bearing 44 on the inner side of the drive seat 41 supports the rotation of the rotating shaft 45. The protective sleeve 43 on the side away from the drive bearing 44 protects the drive bearing 44. The gear 461 on the outer wall of the rotating shaft 45 rotates with the rotating shaft 45. The gear 461 meshes with the traveling rack 462 at the bottom of the crossbeam 2. Through the meshing of the two, the traveling beam 31 is driven to move along the length of the crossbeam 2, thereby realizing the displacement adjustment of the traveling beam 31. In the mounting components 47 on the front and rear sides of the bottom of the traveling beam 31, multiple fixing rings 471 are fixed to the four corners of the bottom of the traveling beam 31 by bolts 472 at the top. The movable bearings 491 inside the fixing rings 471 provide rotational support for the support components 48. The protective sleeves 492 on the side away from the movable bearings 491 protect the movable bearings 491, ensuring the stable installation of the support components 48. The two rotating shafts 481 of the support components 48 rotate with the movable bearings 491. The wheel frame 482 on the outer wall of the rotating shafts 481 contacts the crossbeam 2, which plays an auxiliary support role when the traveling beam 31 moves, reducing the shaking during the movement and improving the stability of the traveling beam 31. The support bearing 36 reduces friction between the wheel axle 34 and the traveling beam 31, ensuring smooth rotation of the wheel axle 34. The drive bearing 44 reduces friction between the rotating shaft 45 and the drive seat 41, ensuring smooth rotation of the rotating shaft 45. The moving bearing 491 reduces friction between the rotating shaft 481 and the fixed ring 471, ensuring flexible operation of the support assembly 48 and enabling the traveling beam 31 to move stably on the crossbeam 2, ultimately completing the anti-scratch transmission of the granite slab.
