Detailed Description

See fig. 2-10.

The present embodiment of the dismounting device for rubber rollers of the present invention comprises a slide hammer 1, a screw 2 and a jacket 3.

The screw rod 2 consists of a hexagonal end head positioned at the lower part and a rod part connected with the end head, a through hole is formed in the center of the sliding hammer 1, and the sliding hammer 1 is sleeved on the rod part through the through hole in a clearance fit mode and abuts against the upper surface of the end head under the action of gravity. The upper end of the rod part is provided with a section of external thread, the jacket 3 is of a cylindrical structure with a bottom and an upward opening, the center of the bottom is provided with a screw hole, and the jacket 3 is matched with the external thread at the upper end of the screw rod 2 through the screw hole and is arranged at the upper end of the screw rod 2. The inner diameter of the side wall of the jacket 3 is the same as the outer diameter of the rubber roller 4 to be disassembled mounted on the bearing 5 of the shaft 6, and opposite sides of the side wall are cut off so that the side wall is composed of two opposite circular arcs with 90-degree angles respectively, so that the two circular arcs can be deviated to the center under the condition of being pressed and clamp the rubber roller 4 to be disassembled.

Wherein, the end head can also be in the shape of a square head.

The upper parts of the two circular arcs are respectively provided with 4 grooves to form 4 teeth parts, so that the rubber roller 4 can be clamped when being disassembled.

As shown in fig. 2, when the rubber roller 4 is removed, first, the operator inserts the toothed portions of the two circular arcs of the opening end of the jacket 3 around the outer surface of the rubber roller 4 and clamps the two circular arcs with force, and clamps the two circular arcs with a fish tail clamp if necessary, so that the 4 toothed portions are slightly inserted into the outer surface of the rubber roller 4, and then slides the slide hammer 1 upward from the bottom of the screw 2, and strikes the hexagonal head of the screw 2 downward by inertia, so that the downward impact force is transmitted to the rubber roller 4 through the jacket 3, thereby removing the rubber roller 4 and the bearing 5 from the shaft 6.

By using the dismounting device, the rubber roller can be dismounted conveniently and quickly, the damage to parts during dismounting is reduced, and the operation time is saved.
