By replacing the counterweight blocks of different weights, the weight of the steel roller can be quickly adjusted to adapt to different working environments and needs, thereby improving the adaptability and production efficiency of the equipment, and making the weight adjustment process simple and quick, greatly improving the convenience of operation.

[0006] The cam is fixedly mounted on the roller bearing cap, and the cam is secured to the roller bearing cap with a plurality of counterweights disposed on the cam.

[0007] Through the above technical solution, the return spring is compressed by sliding the annular sleeve, and then the end cover is moved axially. By replacing the counterweight blocks of different weights, the weight of the steel roller can be quickly adjusted to adapt to different working environments and needs, thereby improving the adaptability and production efficiency of the equipment, and making the weight adjustment process simple and quick, greatly improving the convenience of operation.

[0008] Furthermore, the interior of the sliding cavity is slidably connected with steel balls, and the steel balls are engaged with the annular grooves;

[0009] Through the above technical solution, the steel ball is accurately limited in the annular groove, thereby ensuring that the snap fit between the end cover and the connecting block is tight and stable.

[0010] Furthermore, a mounting hole is provided in the middle of the outer wall of the end cover away from the center of the roller body, and the mounting hole is slidably connected to the main shaft;

[0011] Through the above technical solution, the sliding connection between the mounting hole and the main shaft allows the end cover to be axially adjusted according to actual needs, and is convenient for disassembly and installation of the end cover, and is convenient for daily maintenance and replacement.

[0012] Furthermore, the aperture of the sliding cavity on one side close to the center of the main shaft is smaller than the diameter of the steel ball;

[0013] Through the above technical solution, the steel balls can only roll along a specific path in the sliding cavity, thereby providing a good guiding effect and ensuring that the steel balls will not fall off from the sliding cavity, thereby increasing the overall stability of the equipment.

[0014] Furthermore, the counterweights are arranged symmetrically in pairs with the main axis as the center;

[0015] Through the above technical solution, the overall weight of the steel roller can be effectively balanced, reducing vibration and deviation caused by uneven weight distribution, thereby maintaining stable operation of the equipment.

At this time, the end cover 601 is moved axially, and the steel ball 603 fixed in the annular groove 4 will be separated from its groove position due to the movement of the end cover 601. By replacing the counterweight blocks 5 of different weights, the weight of the steel roller can be quickly adjusted to adapt to different working environments and needs, thereby improving the adaptability and production efficiency of the equipment, and making the weight adjustment process simple and fast, greatly improving the convenience of operation. Secondly, the replacement is completed After the counterweight block 5 is moved, the annular sleeve 604 is slid to compress the return spring 606, thereby reserving space for the steel ball 603 to slide upward. At this time, the end cover 601 is closed and the steel ball 603 fits tightly with the annular groove 4. By loosening the annular sleeve 604, the return spring 606 releases the force to drive the annular boss 605 to reset, thereby limiting the steel ball 603, and then completing the snap-fit ​​cooperation between the end cover 601 and the connecting block 3, ensuring that the steel roller works stably under the new weight configuration. The limitation of the steel ball ensures that the connection between the end cover and the connecting block will not loosen due to vibration or external force, thereby ensuring the structural stability of the entire steel roller.
