[0040] When in use, the installation frame 301 and the large-diameter roller sleeve fixed in the installation frame 301 are placed on the two conveyor belts 102 of the two turnover assemblies 1, and the installation frame 301 and the two conveyor belts 102 are connected; the motor 105 is controlled to work, and the motor 105 can drive the corresponding conveyor roller 109 to rotate, and the rotation of the conveyor roller 109 can drive the conveyor belt 102 to rotate, and the rotation of the conveyor belt 102 will drive the installation frame 301 thereon to move, such as Fig.14 As shown in a in FIG. 1 , the movement of the mounting frame 301 drives the large diameter roller sleeve to move; Fig.14 As shown in b in FIG. 1 , when the installation frame 301 is moved to the starting section of the circular slide rail section 111, the conveyor belt 102 drives the installation frame 301 to continue to move, so that the front end of the installation frame 301 swings upward. Fig.14 As shown in c in FIG. 1 , the installation frame 301 continues to move until the end of the installation frame 301 moves into the circular slide rail section 111. Fig.14As shown in d in 14 and e in 14, because the inner diameter of the circular slide rail section 111 is equal to the diameter of the arc surfaces 307 on both sides of the installation frame 301; the arc surfaces 307 on both sides of the installation frame 301 will slide closely against the inner circular surface of the circular slide rail section 111, and because the distance between two points in the circular slide rail section 111 passing through the center of a circle is the largest, the inner diameter of the circular slide rail section 111 is equal to the diameter of the arc surfaces 307 on both sides of the installation frame 301, and the axis of the arc surfaces 307 on both sides of the installation frame 301 coincides with the axis of the circular slide rail section 111, and the circular slide rail section 111 has an upward supporting force on the installation frame 301, and the installation frame 301 will not fall downward relative to the circular slide rail section 111, and there will be no accidental injury to the staff; when the installation frame 301 is moved to the position as shown in Fig.14 After rotating 180 degrees as shown in f, the bottom of the mounting frame 301 and the large-diameter roller sleeve are supported by the support assembly 4, and then the two sets of flipping assemblies 1 are controlled to slide to both sides to make way for the middle area. During this process, since the inner diameter of the circular slide rail section 111 is equal to the diameter of the arc surfaces 307 on both sides of the mounting frame 301, the two sets of flipping assemblies 1 can be smoothly disengaged from the mounting frame 301 without interference. After that, the support assembly 4 can be controlled to slowly place the mounting frame 301 and the large-diameter roller sleeve on the working base 6, thereby completing the flipping of the large-diameter roller sleeve.

[0041] In a further embodiment, Figure 2 , 3 As shown in , 4, the mounting assembly 3 also includes a side clamping plate 302, an upper clamping plate 303, a first fastening bolt 304, a second fastening bolt 305, and a support ring 306, wherein a circular groove is opened in the middle of the mounting frame 301, and a support ring 306 is fixedly installed at the bottom end of the circular groove, and four second fastening bolts 305 are evenly installed on the mounting frame 301 through threaded fitting, and one end of the four second fastening bolts 305 passes through the circular groove opened in the middle of the mounting frame 301 and is respectively rotatably installed with a side clamping plate 302; four upper clamping plates 303 are evenly installed on the upper side of the mounting frame 301 through the first fastening bolt 304.

[0042] The side and top sides of the large diameter roller sleeve can be clamped by four side clamping plates 302 and four upper clamping plates 303. The mounting assembly 3 designed in the present invention can fix roller sleeves of different diameters and heights, that is, the present invention can realize the flipping of roller sleeves of different diameters and heights.

[0043] In a further embodiment, Figure 5 , 10As shown in 13, four connecting sleeves 308 are symmetrically installed on the lower side of the installation frame 301 by means of ball joints; four telescopic connecting members 103 are symmetrically fixedly installed on the two conveyor belts 102 in the two turnover assemblies 1; the four telescopic connecting members 103 correspond to the four connecting sleeves 308 one by one. The connection between the installation frame 301 and the conveyor belt 102 can be realized by the connecting sleeves 308 and the telescopic connecting members 103, and the connecting sleeves 308 and the telescopic connecting members 103 can be threaded or clamped; the method of connecting the installation frame 301 and the conveyor belt 102 in the present invention is the prior art.

Fig.13 As shown, a plurality of support rollers 104 are evenly and rotatably mounted in the second mounting groove 107. The function of the support rollers 104 is to reduce the movement resistance of the mounting frame 301 during the movement process through rolling friction, and also to provide support force for the mounting frame 301 and the large diameter roller sleeve.

The reason for this design is to ensure that the weight of the installation frame 301 and the large-diameter roller sleeve will not fall on the conveyor belt 102; because the conveyor belt 102 is easy to be damaged relative to the support roller 104, and the support rollers 104 are evenly distributed, when one of them is damaged, only the damaged support roller 104 needs to be replaced or repaired, and all of them do not need to be replaced or repaired, and the subsequent maintenance cost is low.

[0046] In a further embodiment, Fig.12 As shown, two guide bars 108 are symmetrically installed on both sides of the outer end of the first installation slot 106 opened on the circular slide rail section 111; the function of the two guide bars 108 is to guide the conveyor belt 102 wound on the circular slide rail section 111.

[0049] By controlling the two second telescopic hydraulic rods 202, the connecting plate 204 can be controlled to slide relative to the mounting base. The sliding of the connecting plate 204 drives the three fixed slides 205 to slide. The sliding of the fixed slides 205 drives the straight slide rail section 110 to slide. The sliding of the straight slide rail section 110 drives the corresponding flipping assembly 1 to slide, thereby realizing the separation and combination of the two groups of flipping assemblies 1.

[0050] In a further embodiment, Figure 7 As shown, the support assembly 4 includes a support plate 401 and a first telescopic hydraulic rod 402 , wherein the two first telescopic hydraulic rods 402 are fixedly mounted on the working base 6 and are located at the lower side of the two circular slide rail sections 111 ; the support plate 401 is fixedly mounted on the upper side of the two first telescopic hydraulic rods 402 .
