[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that, in the absence of conflict, the embodiments in this application and the features in the embodiments can be arbitrarily combined with each other.

[0024] See also Figures 1 to 5 A roller structure that is easy to disassemble and assemble, wherein a bearing 11 is fixedly provided on the roller shaft 10, and two bearings 11 are provided near the two ends of the roller shaft 10, and a roller sleeve 20 is sleeved on the bearing 11, and the inner wall of the roller sleeve 20 is in close contact with the outer wall of the bearing 11, so that the roller sleeve 20 can rotate relative to the roller shaft 10, and the roller sleeve is provided outside the roller sleeve 20, and the two ends of the roller shaft 10 are respectively connected to the two side plates 30 of the conveyor through fasteners 40 and fixed between the two side plates 30, and the roller shaft 10 provides support for the roller sleeve 20 and the roller thereon, so as to ensure that the roller remains balanced and stable during rotation.

[0025] The fastener 40 includes a spacer 42, a screw 43, and a handle 41. The screw 43 and handle 41 are respectively disposed on either side of the spacer 42. The end of the screw 43 is connected to the spacer 42. The end surface of the roller shaft 10 is provided with a threaded hole, and the screw 43 is disposed in the threaded hole. The screw 43 is threadedly connected to the roller shaft 10. The handle 41 is connected to the spacer 42. Rotating the handle 41 rotates the spacer 42, which in turn rotates the screw 43, thereby tightening the screw 43 and changing the length of the threaded connection between the screw 43 and the roller shaft 10. Preferably, the handle 41 is perpendicular to the screw 43 to increase torque, facilitate the rotation of the screw 43 by the handle 41, and adjust the connection depth of the screw 43.

[0026] Bushings 51 and pads 52 are provided on both sides of the side plate 30. Both the bushings 51 and the pads 52 are provided with through holes for the end of the roller shaft 10 to pass through, and the aperture of the through holes is larger than the outer diameter of the roller shaft 10. The bushing 51 and the pad 52 are coaxially arranged, and the end of the roller shaft 10 passes through the pad 52, the side plate 30, the bushing 51 and the screw 43 in sequence. Under the action of the threaded connection, the side plate 30 is clamped between the bushing 51 and the pad 52, and the end faces on both sides of the side plate 30 are respectively in contact with the end faces of the bushing 51 and the end faces of the pad 52, and the roller shaft 10 is fixed on the side plate 30.

[0027] A spring 12 is sleeved on the end of the roller shaft 10. Spring 12 is positioned between the bearing 11 and the backing plate 52 and is always compressed, ensuring that both ends of the spring 12 maintain contact with the bearing 11 and the backing plate 52, respectively. Turning the handle 41 changes the length of the threaded connection between the screw 43 and the roller shaft 10, which changes the length of the spring 12 between the backing plate 52 and the bearing 11. This changes the elastic force applied by the spring 12 to the backing plate 52, altering the tightening force between the backing plate 52 and the bushing 51 on the side plate 30. This allows for adjustable tension in the roller shaft 10 and quick disassembly. The spring 12 also provides axial cushioning at the end of the roller sleeve 20, reducing axial impact during roller rotation.

[0028] Preferably, a groove 511 is provided on the end face of the bushing 51 facing the pad 42, and a smooth transition is made between the groove 511 and the end face of the bushing 51 through a curved surface. When the fastener 40 fixes the roller shaft 10, the end face of the bushing 51 abuts against the pad 42, and the bushing 51 and the pad 42 are connected in a high-pair manner. The contact area between the bushing 51 and the pad 42 is small, and the pressure is large, which can increase the fastening force between the bushing 51 and the pad 42.

[0029] Specifically, during installation, the handle 41 is turned, the screw 43 penetrates into the interior of the roller 10, and the side plate 30 is clamped between the pad 52 and the bushing 51, connecting the roller 10 and the side plate 30. The handle 41 is continued to be turned to increase the connection length of the screw 43 and the roller 10. The spring 12 located on the same side of the bearing 11 as the fastener 40 is compressed, and its elastic force increases and is applied to the pad 52, pressing the pad 52 toward the side plate 30, further tightening the roller 10 and the side plate 30; during disassembly, the handle 41 is reversed to make the screw 43 disengage from the interior of the roller 10, loosening the side plate 30 and the bushing 51 and the pad 52, reducing the elastic force of the spring 12, and reducing the tightening force between the roller 10 and the side plate 30, making it easier for the roller 10 to separate from the side plate 30.

[0030] The side panels 30 are provided with connecting holes 301, the diameter of which is the same as that of the roller shaft 10. The roller shaft 10 is mounted within the connecting holes 301, and fasteners 40 secure the roller shaft 10 outside the connecting holes 301. To facilitate removal of the roller shaft 10 from between the side panels 30, the side panels 30 are also provided with mounting holes 302, the diameter of which is larger than the diameter of the roller sleeve 20. The mounting holes 302 are located above the connecting holes 301, with the centers of the mounting holes 302 and 301 on the same vertical line. The mounting holes 302 and 301 are connected by a linear slide 303, the width of which is larger than the diameter of the connecting holes 301.

[0031] During installation, first insert the roller shaft 10 with the roller sleeve 20 installed into the installation hole 302, move the roller shaft 10 so that the roller sleeve is located between the two side plates 30, move the roller shaft 10 downward along the linear slide 303 so that both ends of the roller shaft 10 are located in the connecting hole 301, and install the fasteners 40 to fix the roller shaft 10 to the side plate 30; during disassembly, first remove the fasteners 40, move the roller shaft 10 upward along the linear slide 303 so that the roller shaft 10 is located in the installation hole 302, and pull the roller shaft 10 out from the installation hole 302 to complete the disassembly.

[0032] Both ends of the roller shaft 10 are provided with fasteners 40 and springs 12 , and both ends are connected to the two side plates 30 via the fasteners 40 .

[0033] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art will appreciate that modifications may be made to the technical solutions described in the above embodiments, or that some of the technical features may be replaced with equivalents; and such modifications or replacements do not deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
