In the process of pressing and rolling, pressure is applied to the two shaft ends of one roller to make the two rollers press together. During the pressing process, the pressure of the shaft end will cause the working surface to bend and deform, which can easily cause the product to have uneven thickness or liquid content.

[0060] Embodiment 2

[0061] Please refer to Figure 2In an embodiment of the utility model, on the basis that the two ends of first roller 21 and second roller 31 are respectively provided with annular tube capsules, second roller 31 includes second roller body 311 and second mandrel 312 arranged in the inside of second roller body 311, and second roller assembly 30 further includes tubular buffer capsule 35, and tubular buffer capsule 35 abuts against the inner wall of second roller body 311 and the outer wall of second mandrel 312 respectively, since second roller 31 needs to be pressed with first roller 21 under the drive of pressure device 40, by further arranging tubular buffer capsule 35 in second roller 31, tubular buffer capsule 35 can be air capsule or liquid capsule, after air capsule or liquid capsule is pressurized, second roller body 311 is supported, the pressure of pressure device 40 is transmitted to tubular buffer capsule 35 through second mandrel 312, tubular buffer capsule 35 is further transmitted to second roller body 311, and then is uniformly transmitted to first roller 21, the deflection deformation of second roller 31 caused after first roller 21 and second roller 31 are pressed is offset through tubular buffer capsule 35 in second roller 31. That is, the pressure of tubular buffer capsule 35 generates overall pressure on the whole second roller body 311, and the size of overall pressure can be adjusted.

[0062] Wherein, when filling tubular buffer capsule 35 in second roller 31 with fluid, the inside of second mandrel 312 is provided with flow-through groove, flow-through groove is connected with tubular buffer capsule 35 and second rotary joint 34 at the end in communication, second rotary joint 34 is connected with gas source or liquid source, so as to adjust the pressure of tubular buffer capsule 35 through the opening of second rotary joint 34.

[0063] Wherein, in order to guarantee that pressure is applied to each area of second roller body 311, tubular buffer capsule 35 is spirally arranged on the outside of second mandrel 312, that is, spiral tubular buffer capsule 35 covers the surface of second mandrel 312 in the axial direction of second roller body 311, can apply pressure to each position of second roller body 311, guarantees the protection effect of second roller body 311, and as long as one tubular buffer capsule 35 is installed, the installation difficulty and installation cost are reduced compared with the mode that a plurality of tubular buffer capsules 35 are arranged along the circumferential surface of second mandrel 312.

[0064] Further, in order to facilitate the installation of the plurality of spiral-shaped tubular buffer bags 35, the inner wall of the second roller body 311 is provided with a first clamping groove 3111; and / or the outer wall of the second mandrel 312 is provided with a second clamping groove, and the tubular buffer bag 35 is arranged in the first clamping groove 3111 and / or the second clamping groove, that is, only the first clamping groove 3111 is arranged on the inner wall of the second roller body 311, or only the second clamping groove is arranged on the outer wall of the second mandrel 312, or the clamping grooves are arranged on the inner wall of the second roller body 311 and the outer wall of the second mandrel 312, so as to limit the installation of the tubular buffer bag 35 through the arrangement of the clamping grooves, thereby improving the installation efficiency of the tubular buffer bag 35. Understandably, the second clamping groove is spiral-shaped; the second clamping groove can include a plurality of second clamping grooves, each second clamping groove is arc-shaped, and the shape of the tubular buffer bag 35 filled with fluid embedded in the second clamping groove is matched, and the plurality of second clamping grooves are arranged in the axial direction of the second roller body 311; or only one first clamping groove 3111 is arranged, and the entire tubular buffer bag 35 can be arranged in the first clamping groove 3111.

[0065] Further, in another embodiment of the present application, when the tubular buffer bag 35 is arranged in the second roller 31, the second roller assembly 30 is further provided with a plurality of tubular buffer bags 35, and the plurality of tubular buffer bags 35 are sequentially and separately arranged along the axial direction of the second roller 31. When the tubular buffer bags 35 are arranged in a segmented manner, for example, three tubular buffer bags 35 can be arranged along the axial direction of the second roller 31, corresponding to the three length segments of the second roller body 311. The left and right two tubular buffer bags 35 are connected through the interior of the second mandrel 312, and the gas inlet end or liquid inlet end is arranged at one end of the second mandrel 312, for example, at the left end, and the left and right two tubular buffer bags 35 share the same pressure source. The gas inlet end or liquid inlet end of the tubular buffer bag 35 arranged in the middle region is arranged at the other end of the second mandrel 312, for example, at the right end, and a separate pressure source is used, so that when pressurized, the pressures of the two tubular buffer bags 35 at both ends are the same, and the pressure can be adjusted. The pressure of the tubular buffer bag 35 in the middle region can be the same as or different from that at both ends, and the pressure can be adjusted independently. In this way, the pressures of the tubular buffer bags 35 at both ends and the pressure of the tubular buffer bag 35 in the middle region can be adjusted independently according to the deformation sizes of the two ends and the middle part of the second roller 31, and the deformation absorption of the second roller 31 can be better adapted. That is, after the three tubular buffer bags 35 are pressurized, the second roller body 311 is lifted up, the pressure of the pressure device 40 is transmitted to the tubular buffer bags 35 through the second mandrel 312, the tubular buffer bags 35 are uniformly transmitted to the second roller body 311, and then to the first roller 21, and by adjusting the pressure difference of the tubular buffer bags 35 at both ends and in the middle part, the height of the second roller body 311 is adjusted, and the deflection deformation of the second roller 31 caused by the pressure combination of the first roller 21 and the second roller 31 is offset.
