During assembly, one mounting seat 300 is first mounted to one end of the mandrel 100, then the bearings 200 are inserted from the other end of the mandrel 100, and finally the other mounting seat 300 is mounted on the mandrel 100. Finally, the assembled overrunning roller body is mounted on the belt through the mounting seats 300.

[0025] In one embodiment, the mandrel 100 is a linear guide rail with a diameter of 10 mm, which is a cylindrical steel rod.

[0026] In one embodiment, the bearings 200 are 6900 rubber sleeve bearings, which have better dustproof effect than ordinary bearings.

[0027] In one embodiment, as shown, Figure 1 the mounting seat 300 is provided with a screw rod 301 at one end, which matches the bolt hole 101. The mounting seat 300 is provided with mounting holes 302. The mounting seat 300 is connected with the mandrel 100 through bolts. The assembled overrunning roller body is mounted on the belt through the mounting holes 302.

[0028] In one embodiment, as shown, Figure 2 to avoid mutual wear between the bearings 200 and improve the service life of the bearings 200, a limiting assembly 400 for limiting the lateral displacement of the bearings 200 is arranged on the mandrel 100. The limiting assembly 400 is uniformly distributed along the axial direction of the mandrel 100.

[0029] In one embodiment, as shown, Figure 2 the limiting assembly 400 includes grooves 401, springs 402, and steel balls 403. The grooves 401 are arranged on the mandrel 100. The springs 402 and the steel balls 403 are arranged in the grooves 401. The springs 402 are arranged at the lower end of the steel balls 403. When the bearings 200 are inserted into the mandrel 100, the steel balls 403 will move downward under the action of the bearings 200 and external force. After the bearings 200 pass through the steel balls 403, the steel balls 403 will return to the original position under the action of the springs 402. The bearings 200 are sequentially installed between the two steel balls 403, and the lateral movement of the bearings 200 is limited by the steel balls 403.

[0030] In one embodiment, as shown, Figure 3 to prevent foreign matter from invading and causing damage to the bearings 200, a dust removal assembly 500 is arranged on one side of the overrunning roller body. The dust removal assembly 500 is fixed on the mounting seat 300.

[0031] In one embodiment, asFigure 3 As shown, the dust removal assembly 500 includes a ventilation pipe 501 fixed on the mounting seat 300 through connecting columns 502 at both ends, one end of the ventilation pipe 501 is provided with an air inlet 503 for connecting an external air source, and the ventilation pipe 501 is uniformly provided with air outlets 504 on the side close to the over roller body. In use, the external air source is connected to the air inlet 503, and the air is blown to the bearing 200 through the ventilation pipe 501 and the air outlets 504, so as to achieve the purpose of dust removal.

[0032] The above embodiment discloses a half-steel cutting line over roller replacement device, which adopts the structure of sleeving a plurality of bearings 200 on the core rod 100 to replace the roller surface with the bearings 200. In assembly, one mounting seat 300 is first mounted to one end of the core rod 100, then the bearings 200 are inserted from the other end of the core rod 100, and finally the other mounting seat 300 is mounted on the core rod 100. Finally, the assembled over roller body is mounted on the belt through the mounting seat 300. In order to avoid mutual abrasion between the bearings 200 and improve the service life of the bearings 200, a limiting assembly 400 can be arranged on the core rod 100 to limit the lateral movement of the bearings 200. In order to prevent foreign matter from invading and causing damage to the bearings 200, a dust removal assembly 500 can be arranged on one side of the over roller body.
