[0033] As a further implementation of the scheme, the middle shaft 61 is on the same axis line as the roller body 1, the middle shaft 61 rotates inside the positioning ring 8, the middle shaft 61 rotates inside the first connecting frame 2, and the diameter of the middle shaft 61 is the same as the maximum diagonal length of the side section of the connecting block 64. This design enables the center support mechanism 6 to evenly distribute the load, providing uniform support force and reducing local stress concentration, thereby prolonging the service life of the equipment.
[0034] As a further implementation of the present scheme, the thickness of the connecting block 64 is the same as that of the control rotating block 651, the side section of the connecting block 64 is an equilateral hexagon, and a hole of the same size as the connecting block 64 is formed in the inner side of the control rotating block 651. The control rotating block 651 slides in the inner side of the first roller shaft 3. This design enables the control rotating block 651 to slide flexibly in the connecting block 64, improves the compactness of the structure and the flexibility of movement, and facilitates control and adjustment.
[0035] As a further implementation of the present scheme, a plurality of cylindrical grooves are arranged in the inner side of the first roller shaft 3, the snap spring 653 is clamped in the inner side of the first roller shaft 3, the control rotating block 651 is embedded in the inner side of the first roller shaft 3, and two fixed pins 652 symmetrically arranged on the same side of the control rotating block 651 are clamped in the inner side of the first roller shaft 3.

The design of the cylindrical grooves in the inner side of the first roller shaft 3 and the snap spring 653 provides a stable clamping position for the control rotating block 651, provides a reliable fixing and limiting mechanism, and ensures that the control rotating block 651 will not displace during operation.

The support clamping rod 632 is clamped in the inner side of the support rod 631. This design enables the moving beam 73 to be tightly attached to the inner wall of the roller body 1 and clamped with the support clamping rod 632, thereby enhancing the stability and support capacity of the structure and facilitating installation and adjustment.
[0037] As a further implementation of the present scheme, the number of fixed beams 71 is six in total, the fixed beams 71 are evenly distributed in the inner side of the roller body 1, the fixed beams 71 are located between the edge openings of the first connecting frame 2, and the length of the fixed beam 71 plus the thickness of the limiting block 72 is the same as the length of the roller body 1. This design enables the impact resistance mechanism 7 to uniformly bear the load, provides uniform support force, and reduces local stress concentration.
[0038] As a further implementation of the present scheme, six support rods 631 are evenly distributed on the same vertical section of the central shaft 61, the support clamping rods 632 connected by the support rods 631 are oriented in the same direction of rotation, and the support clamping rods 632 are arc-shaped rods with the central shaft 61 as the center. This design enables the support rods 631 to uniformly support the moving beam 73, improves the uniformity and stability of the support structure, and reduces structural deformation caused by uneven support.
[0039] Work flow: when using the anti-impact sinking roller, according to the performance requirements of the sinking roller, the movable beams 73 of different materials and strengths are slid into the fixed beams 71 until the movable beams 73 and the fixed beams 71 are in the same vertical plane, and the other end of the movable beams 73 is in close contact with the limiting block 72. After the movable beams 73 and the fixed beams 71 are installed one by one, the tool is used to take out the snap spring 653 from the first roller shaft 3 to release the parallel movement restriction of the control rotating block 651 by the snap spring 653. Then the specially designed magnetic attraction device is used to attract the control rotating block 651 to take it out of the first roller shaft 3. During the sliding process of the control rotating block 651 in the first roller shaft 3, the fixed pin 652 fixedly connected with the control rotating block 651 is separated from the clamping hole in the first roller shaft 3, thereby releasing the rotating movement control of the control rotating block 651 on the connecting block 64. After the control rotating block 651 is taken off, the control rotating block 651 is reversely installed outside the connecting block 64, so that one end of the fixed pin 652 connected with the control rotating block 651 faces away from the first roller shaft 3. The operator can apply a rotating force to the fixed pin 652 to make the fixed pin 652 rotate the connecting block 64 through the control rotating block 651, and then the connecting block 64 drives the middle shaft 61 to rotate inside the roller body 1. Step by step, the middle shaft 61 rotates while the support rod 631 fixedly connected with the middle shaft 61 rotates around the axis of the middle shaft 61, until the support rod 631 is clamped into the hole inside the movable beam 73. At this time, the movable beam 73 and the support rod 631 and the middle shaft 61 form a relatively stable support structure, which can provide good support for the inside of the roller body 1. Finally, the control rotating block 651 and the fixed pin 652 are installed reversely, so that the fixed pin 652 is clamped into the other pin hole in the first roller shaft 3, and the position of the middle shaft 61 is fixed and limited, so that the roller body 1 of the sinking roller has strong anti-impact performance.
[0040] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
