[0035] Specifically, the roller shaft positioning and clamping assembly includes a first roller shaft positioning and clamping mechanism 2 and a second roller shaft positioning and clamping mechanism 3. The first roller shaft positioning and clamping mechanism 2 and the second roller shaft positioning and clamping mechanism 3 position and clamp the two ends of the roller shaft 10 along the axial direction of the roller shaft 10. The first roller shaft positioning and clamping mechanism 2 and the second roller shaft positioning and clamping mechanism 3 have the same structure, and the first roller shaft positioning and clamping mechanism 2 is explained here.

[0036] like Figure 2-3As shown, the first roller shaft positioning and clamping mechanism 2 includes a positioning seat 1 21 and a clamping cylinder 1 22 connected to the air circuit mechanism 7. The positioning seat 1 21 is provided with a positioning member 1 23, a positioning member 24 and a positioning member 4 27. It also includes a clamping member 1 25 connected to the clamping cylinder 1 22. One end of the clamping member 1 25 is hinged to the piston rod of the clamping cylinder 1 22, and the other end is fixedly connected to a positioning member 3 26. The clamping cylinder 1 22 controls the positioning member 3 26 to be located in a clamping position or a release position: in the clamping position, the positioning member 1 23, the positioning member 24 and the positioning member 3 26 are arranged around the circumference of the first end 15 of the roller shaft 10 and clamp the roller shaft 10; in the release position, the positioning member 3 26 is away from the roller shaft 10; the positioning member 4 27 is used to position the end face of the first end 15 of the roller shaft 10. The specific clamping action process is as follows: the air circuit mechanism 7 controls the movement of the piston rod of the clamping cylinder 22, and drives the clamping member 25 and the positioning member 3 26 to approach the positioning member 1 23 and the positioning member 2 24, so as to realize the positioning and clamping of the drum shaft 10.

[0037] The structure of the second roller shaft positioning and clamping mechanism 3 is the same as that of the first roller shaft positioning and clamping mechanism 2. The second roller shaft positioning and clamping mechanism 3 is used to position and clamp the second end 16 of the roller shaft 10 and to position the second end surface of the second end 16, which will not be described in detail here.

[0038] The four sets of web positioning mechanisms have the same structure. Here, the structure of any one set of web positioning mechanisms 4 is used for description. Figure 4 The web positioning mechanism 4 includes a connected positioning member 41 and an I-type adjustment reference block 43, a single-hole adjustment gasket 44 is arranged between the positioning member 41 and the I-type adjustment reference block 43, a positioning groove 42 is arranged on the positioning member 41, and the positioning groove 42 is used to support and position the bottom circumference of the vertically placed web. The position of the positioning member 41 is adjustable to ensure accurate support and positioning of the web. Specifically, the I-type adjustment reference block 43 is fixedly arranged, and the positioning member 41 is movably arranged. The position of the positioning member 41 is adjusted by increasing or decreasing the number of single-hole adjustment gaskets 44 between the positioning member 41 and the I-type adjustment reference block 43.

[0039] The composition structures of the four sets of web positioning and clamping mechanisms are the same. Any one of the sets of web positioning and clamping mechanisms is used for explanation. The web positioning and clamping mechanisms include a first web positioning and clamping mechanism 5 and a second web positioning and clamping mechanism 6. The first web positioning and clamping mechanism 5 and the second web positioning and clamping mechanism 6 are used for positioning and clamping different positions of the same web.

[0040] The first web positioning and clamping mechanism 5 and the second web positioning and clamping mechanism 6 in the set of web positioning and clamping mechanisms are arranged at intervals, and the connecting line therebetween is parallel to the plane of the web; the web positioning mechanism 4 used for cooperating with the set of web positioning and clamping mechanisms to position the same web is located between the first web positioning and clamping mechanism 5 and the second web positioning and clamping mechanism 6 to achieve accurate positioning and clamping of the same web.

[0041] See also Figure 5-6 The first web positioning and clamping mechanism 5 includes a positioning seat 2 51 and a clamping cylinder 2 52 connected to the air circuit mechanism 7, and also includes a clamping piece 2 53 and a positioning piece 6 54 connected to the clamping cylinder 2 52, one end of the clamping piece 2 53 is hinged to the piston rod of the clamping cylinder 2 52, and the other end is connected to the positioning piece 6 54; a two-hole adjustment gasket 1 56 is also provided between the clamping piece 2 53 and the positioning piece 6 54 to adjust the position of the positioning piece 6 54. Specifically, by increasing or decreasing the number of the two-hole adjustment gasket 1 56, after the clamping cylinder 2 52 drives the clamping piece 2 53 to move into place, the position of the positioning piece 6 54 is adjusted, that is, the distance between the positioning piece 6 54 and the positioning seat 2 51 can be adjusted, so as to be used for positioning and clamping webs of different thicknesses. Under the control of the air circuit mechanism 7, the clamping cylinder 2 52 drives the positioning member 6 54 to be in the clamping position or the loosening position. In the clamping position, one end face of the web disc bears on the positioning seat 2 51, and the other end face of the web disc is clamped by the positioning member 6 54. In the loosening position, the positioning member 6 54 is away from the end face of the web disc. The positioning seat 2 51 is also provided with a hole positioning mechanism for positioning the through hole on the web disc. The hole positioning mechanism includes a pin hole and a positioning pin 55 provided on the positioning seat 2 51. The positioning pin 55 is passed through the pin hole on the positioning seat 2 51 and the through hole on the web disc in sequence, thereby realizing the hole positioning of the web disc. The positioning pin 55 is a diamond-shaped positioning pin to ensure accurate positioning.

A two-hole adjustment gasket two 65 is arranged between the clamping piece three 63 and the positioning piece seven 64. Under the control of the air circuit mechanism 7, the clamping cylinder three 62 drives the positioning piece seven 64 to have a clamping position or a loosening position. In the clamping position, one end face of the web rests on the positioning seat three 61, and the other end face of the web is clamped by the positioning piece seven 64. In the loosening position, the positioning piece seven 64 is away from the end face of the web.
