[0037] like Figures 1 to 5The side protection mechanism in the present application includes an upper protection member 5, a lower protection member 6, an inner protection member 7 and an outer protection member 8. The relative positions of the above protection members are that the upper protection member 5 is located at the top, the lower protection member 6 is located at the bottom, the inner protection member 7 is located close to the length center direction of the roller 2, and the outer protection member 8 is located away from the length center direction of the roller 2. The upper protection member 5, the inner protection member 7, the lower protection member 6 and the outer protection member 8 are detachably connected in sequence to form a first accommodating portion 9. The length direction of the first accommodating portion 9 is the same as the conveying direction of the roller conveyor 1. The sprockets 3 fixed at both ends of the roller 2 are respectively placed in the first accommodating portions 9 on both sides in parallel along the length direction, which protects the sprockets 3. The upper guard 5, the lower guard 6, the inner guard 7 and the outer guard 8 are all strip-shaped parts whose length direction is the same as the conveying direction. They can be stocked in batches according to standard lengths and assembled in different lengths of roller conveyors 1 by splicing. The upper guard 5, the lower guard 6, the inner guard 7 and the outer guard 8 are all detachably connected, which is convenient for disassembly and assembly, and can be disassembled and replaced separately, saving costs.

[0038] In some embodiments, as Figures 1 to 8 As shown, the inner protective member 7 includes several groups of first protective plates 11, second protective plates 12 and third protective plates 13 connected in parallel in sequence, wherein the first protective plate 11 and the second protective plate 12 are mirror-symmetrical, and the same-shaped plates can be used in stocking to replace different front and back as the first protective plate 11 and the second protective plate 12. After the adjacent first protective plates 11 and the second protective plates 12 are connected, a second accommodating portion 10 with an opening direction downward is formed, wherein the second accommodating portion 10 can pass through the end shaft 201 of the roller 2, and the end shaft 201 is a circular shaft end with a smaller diameter located at both ends of the roller 2 for connecting the sprocket 3. The third protective plate 13 is a rectangular plate. When applied to rollers with different spacings, a third protective plate 13 of appropriate length can be selected to change the spacing between adjacent groups of second accommodating portions 10. The modular design saves costs and improves applicability.

[0039] In some embodiments, as Figures 3 to 9 As shown, the upper protective member 5 has a first card slot 501 opening toward the length center direction of the roller 2, and the upper ends of the first protective plate 11, the second protective plate 12 and the third protective plate 13 are each provided with a first clip 701 on the side away from the length center direction of the roller 2.
