[0026] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] Example 1

[0028] Combined with attachment Figure 1 A wear-resistant rubber roller for papermaking comprises a rotating shaft 1 and a roller core 2 sleeved on the rotating shaft 1, a rubber cylinder 3 is sleeved on the roller core 2, a plurality of slide grooves 4 are evenly arranged along the length direction of the roller core 2 on the circumference of the roller core 2, a forward and reverse screw 5 is arranged in the slide groove 4, one end of the forward and reverse screw 5 extends to the outside of the roller core 2 and is connected with a hexagonal head 6, a slider 7 symmetrically arranged in the slide groove 4 is threadedly connected to the forward and reverse screw 5, a connecting rod 8 is hinged on the slider 7, and the other end of the connecting rod 8 is hinged with an arc plate 9 that abuts the inner wall of the rubber cylinder 3.

[0029] The roller core 2, the connecting rod 8 and the arc-shaped plate 9 form an equilateral trapezoidal structure.

[0030] Attach a socket wrench to the hexagonal head 6 and rotate it. This drives the forward and reverse screws 5, which in turn move the sliders 7 closer or further apart. This in turn adjusts the distance between the connecting rods 8 and the distance between the curved plate 9 and the rotating shaft 1, allowing the device to adapt to different diameters of rubber cartridges 3.

[0031] One end of the roller core 2 is provided with a countersunk hole 10 arranged around the forward and reverse screws 5. The hexagonal head 6 is arranged in the countersunk hole 10, which can hide the hexagonal head 6 and will not hinder the installation of the extension ring 12.

[0032] An anti-skid pad 11 is provided on the outer side wall of the arc-shaped plate 9 , and the anti-skid pad 11 abuts against the rubber tube 3 . The anti-skid pad 11 can make the rubber tube 3 and the arc-shaped plate 9 fit more tightly.

[0033] Example 2

[0034] The ends of the roller core 2 are provided with several extension rings 12 in sequence to increase the length of the roller core 2. The rubber cylinder 3 extends to the extension rings 12. By adding the extension rings 12, the length of the roller core 2 can be increased, so that the device can adapt to rubber cylinders 3 of different lengths.

[0035] The end of the roller core 2 is evenly provided with a plurality of blind screw holes 13, and the extension ring 12 is provided with screw holes 14 that match the blind screw holes 13. The blind screw holes 13 and the screw holes 14 are provided with studs 15 that connect the roller core 2 and the extension ring 12, and the extension ring 12 and the extension ring 12.

[0036] The stud 15 has no head and can be hidden in the screw hole 14 . When a plurality of extension rings 12 are added, no gap will be left between the roller core 2 and the extension rings 12 .
