[0043] Embodiment 1

[0044] Please refer to Figures 2 - 4 , an intermediate roll spacing adaptive adjustment mechanism in a five-roll calender, including a driving link 13, the driving link 13 is used to adjust the calender rolls 17, the calender rolls 17 include a first calender roll 5, a second calender roll 6, a third calender roll 7, a fourth calender roll 8, and a fifth calender roll 9.

[0048] Please refer to Figures 1 - 4 , on the basis of Embodiment 1, one end of a first linkage rod 12 is rotatably connected to the upper end of the driving link 13, and the other end of the first linkage rod 12 is rotatably connected to the first calender roll 5 through a rotating shaft 11;

[0049] One end of a fourth linkage rod 16 is rotatably connected to the lower end of the driving link 13, and the other end of the fourth linkage rod 16 is rotatably connected to the fifth calender roll 9 through a rotating shaft 11;

[0050] One end of a second linkage rod 14 is rotatably connected to the middle position of the upper half of the driving link 13, and the other end of the second linkage rod 14 is rotatably connected to the second calender roll 6 through a rotating shaft 11;

[0051] One end of a third linkage rod 15 is rotatably connected to the middle position of the lower half of the driving link 13, and the other end of the third linkage rod 15 is rotatably connected to the fourth calender roll 8 through a rotating shaft 11;

[0052] The rotating shafts 11 connected to the first calender roll 5, the second calender roll 6, the third calender roll 7, the fourth calender roll 8, and the fifth calender roll 9 are all slidably connected to the sliding groove 10.

[0054] The length of the first linkage rod 12 is greater than the length of the fourth linkage rod 16;

[0055] The length of the fourth linkage rod 16 is greater than the length of the second linkage rod 14;

[0056] The length of the second linkage rod 14 is greater than the length of the third linkage rod 15.

[0057] The length of the first linkage rod 12 is equal to the distance between the connection point of the first linkage rod 12 on the drive linkage rod 13 and the rotation axis of the third pressure roller 7;

[0058] The length of the second linkage rod 14 is equal to the distance between the connection point of the second linkage rod 14 on the drive linkage rod 13 and the rotation axis of the third pressure roller 7;

[0059] The length of the third linkage rod 15 is equal to the distance between the connection point of the third linkage rod 15 on the drive linkage rod 13 and the rotation axis of the third pressure roller 7;

[0060] The length of the fourth linkage rod 16 is equal to the distance between the connection point of the fourth linkage rod 16 on the drive linkage rod 13 and the rotation axis of the third pressure roller 7.

[0061] The chute 10, the first pressure roller 5, the second pressure roller 6, the third pressure roller 7, the fourth pressure roller 8, and the fifth pressure roller 9 are all arranged in the machine housing 1.

[0062] The driving device 3 is a driving motor.

[0063] The working principle and beneficial effects of the above solution:

[0064] By setting the driving rods of different pressure rollers to different lengths, the intervals between the first pressure roller 5, the second pressure roller 6, the third pressure roller 7, the fourth pressure roller 8, and the fifth pressure roller 9 gradually decrease. During the adjustment process, the form of gradually decreasing intervals can still be maintained. When calendaring, the intervals through which the material passes will decrease in sequence. Compared with the situation where the intervals between the pressure rollers in the existing five-roller calender are the same, the pressure of the calendared material on the pressure rollers in this application is significantly reduced, which is beneficial to protecting the pressure rollers and ensuring the service life of the pressure rollers.

[0065] Embodiment 3

[0066] Please refer to Figure 4, on the basis of Embodiments 1-2, the calender rolls 17 are connected by a stability-maintaining assembly. The stability-maintaining assembly includes a first gear 18 and a fourth gear 24 respectively arranged on adjacent calender rolls 17. The first end of a first maintaining rod 21 is rotatably connected to the first gear 18, and the first end of a second maintaining rod 22 is rotatably connected to the fourth gear 24. The second end of the first maintaining rod 21 is rotatably connected to the second end of the second maintaining rod 22;

[0067] A second gear 20 is rotatably connected to the joint of the first maintaining rod 21 and the second maintaining rod 22, and the second gear 20 meshes with the first gear 18;

[0068] A third gear 23 is rotatably connected to the second maintaining rod 22, and the third gear 23 meshes with both the second gear 20 and the fourth gear 24.

[0069] The working principle and beneficial effects of the above solution:

[0070] During the rotation of the calender rolls, one group of calender rolls 17 rotates under the action of the driving device 3, driving the first gear 18 to rotate. Since the second gear 20, the third gear 23 and the fourth gear 24 are meshed, at this time, the fourth gear 24 will rotate. And because the second gear 20, the third gear 23 and the fourth gear 24 are all connected to the second maintaining rod 22, when the second maintaining rod 22 rotates, it will not affect the transmission between the second gear 20, the third gear 23 and the fourth gear 24. Also, because the first gear 18 and the second gear 20 are both connected to the first maintaining rod 21, when the first maintaining rod 21 rotates, it will not affect the transmission between the first gear 18 and the second gear 20. That is, when the distance between the two groups of calender rolls 17 changes, it will not affect the transmission between the calender rolls 17. Compared with each group of calender rolls 17 being controlled by a set of drive, this solution has better synchronism.

[0071] Embodiment 4

[0072] Please refer to Figures 5 - 6 , on the basis of Embodiments 1-3, a safety assembly is arranged between the driving device 3 and the calender rolls 17, and the safety assembly is used to protect the driving device 3.

[0073] The safety assembly includes a drive shaft 36, and a drive gear 37 is fixedly connected to the drive shaft 36. The drive gear 37 is connected to the driving device 3;

[0074] A linkage ring 28 is fixedly connected to the drive shaft 36. A first rotating ring 26 is arranged outside the linkage ring 28. The first rotating ring 26 is fixedly connected to the drive shaft 36, and a first protrusion 27 is arranged on one end face of the first rotating ring 26;

[0075] A number of jacks 29 are provided on the side of the linkage ring 28. A plug block 31 is slidably connected in the jack 29, and a spring 30 is provided between the plug block 31 and the jack 29;

[0076] A second rotating ring 32 is provided on one side of the linkage ring 28. A sliding sleeve 33 is fixedly connected to the second rotating ring 32. A slot 34 is provided in the sliding sleeve 33. A plug shaft 35 is slidably inserted in the slot 34, and the plug shaft 35 is connected to the calender roll 17;

[0077] An inner ring sleeve 38 and an outer ring sleeve 39 are provided on the inner circumference of the second rotating ring 32. There is a step between the inner ring sleeve 38 and the outer ring sleeve 39. A sliding slot 41 is provided on the inner ring sleeve 38, and a second protrusion 40 is provided on the inner ring sleeve 38.

[0078] The plug block 31 can be slidably connected in the sliding slot 41, and the plug block 31 can be slidably connected in the outer ring sleeve 39.

[0079] The working principle and beneficial effects of the above solution:

[0080] When there is a large amount of material between adjacent calender rolls 17 and the compression ratio is large, the pressure on the calender roll 17 will increase, that is, the load on the driving device 3 that drives the calender roll 17 to rotate will increase. When it reaches a certain level, it will cause damage to the motor and even burn it out. Setting up a safety component helps to protect the driving device 3;

[0081] When the load of the calender roll 17 exceeds the limit transmitted by the plug block 31, the plug block 31 will compress the spring 30 and enter the jack 29, and the plug block 31 will disengage from the sliding slot 41. That is, at this time, the driving device 3 only needs to drive the plug block 31 to rotate against the friction with the inner ring sleeve 38, and the load is greatly reduced, which helps to protect the driving device 3;

[0082] In this case, the first protrusion 27 on the first rotating ring 26 that rotates with the drive shaft 36 will push out the second rotating ring 32, and the linkage ring 28 will move into the outer ring sleeve 39. At this time, the plug block 31 only needs to overcome the sliding friction with the outer ring sleeve 39 to rotate. Compared with the undulating state between the plug block 31 and the several sliding slots 41 of the inner ring sleeve 38, the load on the driving device 3 is reduced once again, ensuring the safety of the driving device 3.

[0083] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention. Any reference signs in the claims should not be construed as limiting the claims involved.
