[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a rubber roller for easy replacement of rubber surface, comprising a rubber roller main body 1, the rubber roller main body 1 comprising a roller core 8 and a rubber surface 9, the rubber surface 9 is sleeved on the outer side of the roller core 8 through a mounting mechanism, the mounting mechanism comprising a protrusion 10 and a groove 11, a first mounting plate 2 and a second mounting plate 4 are symmetrically fixedly arranged at both ends of the roller core 8, a first connecting shaft 3 is pivotally mounted on one end of the first mounting plate 2, a second connecting shaft 5 is mounted on one end of the second mounting plate 4 through a limiting mechanism, the first connecting shaft 3 and the second connecting shaft 5 have the same specifications, and one end of the first connecting shaft 3 and the second connecting shaft 5 are both "U"-shaped, the first mounting plate 2 can rotate inside the first connecting shaft 3, so as to facilitate the rotation adjustment of the rubber roller main body 1, and the rubber roller does not need to be disassembled as a whole, the operation is simple and convenient, and the practicability is high.

[0022] In this embodiment, the protrusion 10 is circular and fixedly arranged on the inner wall of the rubber surface 9, the shape of the rubber surface 9 is cylindrical, the groove 11 is circular and opened on the outer surface of the roller core 8, one end of the groove 11 is a closed section, the protrusion 10 is installed inside the groove 11, and the limiting mechanism is arranged on one side of the protrusion 10. Through the clamping connection between the groove 11 and the protrusion 10, the rubber surface 9 can be quickly installed, and the roller core 8 and the rubber surface 9 can be limited to prevent sliding between the roller core 8 and the rubber surface 9.

[0023] In this embodiment, the limiting mechanism includes a swivel 6, which is screwed on the outer side of one end of the second connecting shaft 5 by threading. The swivel 6 is arranged on the outer side of the second mounting plate 4, and the thread is opened on the outer wall of one end of the second connecting shaft 5. A limiting rod 7 is symmetrically fixed on one side of the swivel 6, and one end of the limiting rod 7 is in contact with the protrusion 10. The swivel 6 is screwed and rotated to adjust the swivel 6 to the outer side of the second mounting plate 4, so as to limit the second mounting plate 4 and facilitate the limiting and fixing of the rubber roller body 1. The limiting rod 7 is in contact with the protrusion 10 and can limit the rubber surface 9 through the protrusion 10, thereby preventing the rubber surface 9 from lateral movement, which can improve the stability of the rubber roller.

[0024] When using the rubber roller that is easy to replace the rubber surface, the first connecting shaft 3 and the second connecting shaft 5 are installed on the rubber roller mounting frame, and the first connecting shaft 3 or the second connecting shaft 5 is connected to the transmission equipment. When the rubber surface 9 needs to be replaced, the rotating ring 6 is screwed on the second connecting shaft 5, the rotating ring 6 is moved away from the outside of the second mounting plate 4, and the roller core 8 is rotated. The roller core 8 drives the first mounting plate 2 to rotate inside the U-shaped end of the first connecting shaft 3, and one end of the second mounting plate 4 is moved out from the inside of the second connecting shaft 5, and the rubber surface 9 is removed from the roller core 8 and the second mounting plate 4. The outer side is taken off, and the new rubber surface 9 is put on the roller core 8 through the protrusion 10 and the groove 11. The protrusion 10 is installed inside the groove 11, and the rubber roller body 1 is rotated in the opposite direction, and the second mounting plate 4 is rotated into the inside of the U-shaped end of the second connecting shaft 5. The swivel 6 is rotated in the opposite direction. The swivel 6 moves to the outside of the second mounting plate 4 to limit the second mounting plate 4 and prevent the rubber roller body 1 from rotating. At the same time, the limiting rod 7 contacts and aligns with one side of the protrusion 10 for limiting. There is no need to disassemble the rubber roller, which is simple to operate, saves time and effort, and is highly practical.
