[0020] Reference Figure 1-5 , a device for disassembling and replacing roller skins, comprising a main frame 13, on which a roller skin replacement assembly 12, a robotic arm 10, and a lifting roller 9 are provided. The roller skin replacement assembly 12 comprises a replacement frame 128, which is fixedly connected to the main frame 13, and a roller skin storage bin 127 and an electric push rod 126 are fixedly connected to the replacement frame 128. A second bearing seat clamp 125 is fixedly connected to the electric push rod 126, and a second withdrawal drill 124 is provided on the second bearing seat clamp 125. A first bearing seat clamp 121 is fixedly connected to the main frame 13, and the first bearing seat clamp 121 is inserted into the roller. The first bearing seat clamp 121 is fixedly connected on all sides. The first withdrawing drill 122 and the replacement frame 128 are provided with a mechanical clamp 123, which fixes the roller. By setting the lifting roller 9, when the equipment is online, the roller that needs to be replaced is replaced, the conveyor belt is lifted, and the pressure of the replaced roller is released to achieve the purpose of disassembling the roller. When the mechanical arm 10 takes the roller out of the equipment and places it on the roller bearing seat clamp 121, the electric push rod 126 extends to clamp the roller bearing seat. After the roller is placed, the mechanical clamp 123 clamps the roller. Finally, the electric push rod 126 feeds in to disengage the bearing seat and take out the roller skin. At the same time, the new roller skin in the roller skin storage bin 127 is manually replaced to replace the roller skin, so as to realize online replacement of the roller skin, which is convenient and quick to operate.

[0021] The lifting roller 9 includes an electric motor 98, which is installed on the main frame 13. The main frame 13 is fixedly connected to a rotating shaft hinge support 97. The rotating shaft hinge support 97 is rotatably connected to a rotating shaft 91. When the rotating shaft 91 rotates, the lower support seat of the side roller support 92 can be pushed inward or outward through a thread to adjust the height and angle of the side roller 93. The rotating shaft 91 is transmission-connected to the electric motor 98 through a connecting mechanism. Both ends of the rotating shaft 91 are threadedly connected to side roller support parts 92. The two side roller support parts 92 are hinged to the side rollers 93. Two hinge supports 95 are sleeved on the rotating shaft 91. A middle roller 94 is arranged between the two hinge supports 95. The two side rollers 93 are respectively hinged to the hinge supports 95, and the two hinge supports 95 are fixed by a fixing mechanism.

[0022] The fixing mechanism includes a snap ring 96. A snap ring 96 is provided on the relative outer sides of the two hinge supports 95. The two snap rings 96 are fixedly connected to the rotating shaft 91. The middle hinge support 95 is fixed in position by the snap ring 96. The middle roller 94 can be positioned and fixed according to the length of the middle roller 94.
