[0025] like Figures 1 to 5 As shown, a through-axis aluminum guide roller comprises a roller body 1 and a coupling shaft 2, wherein a mounting hole 11 is provided in the middle of the roller body 1, and a plurality of reinforcing blocks 12 are evenly arranged on the inner wall of the mounting hole 11, wherein the reinforcing blocks 12 are arc-shaped blocks, and mounting grooves 13 are provided at both ends of the mounting hole 11, and a plurality of grooves 21 are provided on the outer circumference of the coupling shaft 2, wherein the plurality of grooves 21 correspond to the plurality of reinforcing blocks 12 one by one, and the grooves 21 are arc-shaped, and the shape of the grooves 21 matches the shape of the reinforcing blocks 12, and the coupling shaft 2 is connected to the reinforcing blocks 12 through the grooves 21. The block 12 is slidably arranged in the mounting hole 11 of the roller body 1, and the installation is convenient and fast. A plurality of first threaded holes 121 are provided on both side walls of the reinforcing block 12, and a cover 3 is provided in the mounting groove 13. A plurality of countersunk holes 31 are provided on the side wall of the cover 3. The plurality of countersunk holes 31 correspond to the plurality of first threaded holes 121 one by one, and a locking nut is passed through the countersunk hole 31 and screwed into the first threaded hole 121, and the coupling 2 is limited by the two covers 3 to prevent the coupling 2 from shaking in the mounting hole 11 of the roller body 1.

[0026] Combination Figure 5 and Figure 6As shown, in this embodiment, a plurality of card grooves 14 are provided on the inner wall of the installation groove 13, and a connecting head 4 is carded in the installation groove 13. The connecting head 4 includes a mounting portion 41 and a connecting portion 42. A plurality of protrusions 411 are provided on the outer circumferential surface of the installation portion 41, and the protrusions 411 are slidably carded in the card groove 14. A plug hole 412 is provided in the middle of the side wall of the connecting head 4, and a plurality of sliders 413 are evenly arranged on the inner wall of the plug hole 412. Both ends of the connecting shaft 2 are provided with a mounting shaft 22, and a plurality of slide grooves 23 are evenly arranged on the outer circumferential surface of the mounting shaft 22. A second threaded hole 24 is provided at the bottom of the slide groove 23, and the slider 413 is slidably carded in the slide groove 23. With this structure, the transmission can be carried out through the connecting head 4 and the external power mechanism, so as to effectively protect the connecting shaft 2 and prevent the connecting shaft 2 from being worn during use, thereby extending the service life of the connecting shaft 2 and the roller body 1.

[0027] Combination Figure 6 As shown, a keyway 421 is provided on the outer circumferential surface of the connecting portion 42, and a key is arranged in the keyway 421 to be connected to an external gear, which is transmitted through the gear and the power mechanism to drive the aluminum guide roller to rotate.

The connector 4 is limited by the card slot 14 and the slide slot 23 so that it can only slide in the horizontal direction. The locking screw 5 is screwed into the third threaded hole 422 and the second threaded hole 24 in sequence to limit the connector 4 in the horizontal direction. The connector 4 is clamped and locked after double limiting. A key is inserted into the key slot 421 to connect it to the external gear. The gear is connected to the external power mechanism through transmission. The power mechanism drives the connector 4 to rotate, which can drive the aluminum guide roller to rotate and work, thereby reducing the wear of the connecting shaft 2 and the roller body 1, effectively protecting the connecting shaft 2 and the roller body 1, and extending the service life of the connecting shaft 2 and the roller body 1. When the aluminum guide roller cannot work due to severe wear, only the connector 4 needs to be replaced, which is convenient to replace and saves costs.
