Wherein, the connecting assembly 3 is installed in the inner side of rack 2, it can be in the left side of balance roller assembly, it can be in the right side of balance roller assembly. The structure of the balance roller assembly can be same with the structure of existing swing type balance roller, and one end of balance roller assembly is located in first aligning ball bearing, thereby ensuring that balance roller assembly and connecting assembly 3 keep the rotating connection relationship.

[0037] Further, the balance roller further includes first fixed seat 5, first swing seat 6, second aligning ball bearing 7, first driving mechanism 8.

[0038] The first fixed seat 5 and the connecting assembly 3 are also arranged on the inner side of the rack 2, and the first fixed seat 5 and the connecting assembly 3 are respectively arranged on two sides of the balancing roller assembly. The first swing seat 6 is arranged on the inner side of the first fixed seat 5, and the first swing seat 6 is swing-connected with the first fixed seat 5. The second self-aligning ball bearing 7 is arranged in the first swing seat 6, and the second self-aligning ball bearing is sleeved on the balancing roller assembly, so that the other end of the balancing roller assembly is rotationally connected with the first swing seat 6. The first driving mechanism 8 is arranged below the first swing seat 6, and is used for driving the first swing seat 6 to swing, so that the balancing roller assembly and the one end of the first swing seat 6 connected with each other can swing up and down, so that the change of the paper tension can be realized.

[0039] For example, when it is detected that the surface temperature of the paper on the side of the first swing seat 6 is lower than the surface temperature of the paper on the side of the connecting assembly 3 after the paper passes through the preheating cylinder, the first driving mechanism 8 drives the first swing seat 6 to swing downward to a proper angle, so that the tension of the paper on the side of the balancing roller assembly connected with the first swing seat 6 is increased, so that the side of the paper with low temperature is more closely contacted with the preheating cylinder, the degree of contact of the two sides of the paper with the preheating cylinder is more consistent, and the problem of uneven heating of the paperboard can be solved. On the contrary, when it is detected that the surface temperature of the paper on the side of the first swing seat 6 is higher than the surface temperature of the paper on the side of the connecting assembly 3 after the paper passes through the preheating cylinder, the first driving mechanism 8 drives the first swing seat 6 to swing upward to a proper angle, so that the tension of the paper on the side of the balancing roller assembly connected with the first swing seat 6 is reduced, so that the side of the paper with high temperature is more loosely contacted with the preheating cylinder, the degree of contact of the two sides of the paper with the preheating cylinder can be restored to be more consistent, and the problem of uneven heating of the paperboard can be solved.

[0040] It can be seen that the first fixed seat 5 is arranged on the inner side of the rack 2, and the first swing seat 6 is arranged on one side of the balancing roller assembly and swing-connected with the first fixed seat 5, so that the swing angle of the side end of the balancing roller assembly can be adjusted by the mode that the first driving mechanism 8 drives the first swing seat 6 to swing, the change of the paper tension is realized, and the paper and the preheating cylinder are fully contacted. Compared with the existing mechanical swing type balancing roller, the swing angle of the side end of the balancing roller assembly does not need to be adjusted manually, and the production line of the paperboard does not need to be stopped when the first driving mechanism 8 adjusts the swing angle of the side end of the balancing roller assembly, so that the production efficiency of the corrugated paperboard cannot be reduced.

[0041] In a preferred embodiment of the present utility model, the upper side of the first fixed seat 5 is connected with a horizontally arranged fixed shaft 9, which is fixed with the first fixed seat 5. The fixed mode can be that the fixed shaft 9 is fixedly inserted into the first fixed seat 5, or that the fixed shaft 9 is penetrated through the first fixed seat 5 and then fixed by a nut. The upper side of the first swing seat 6 is sleeved on the fixed shaft 9, so that the first swing seat 6 can swing around the fixed shaft 9 as the swing center.

[0042] It can be understood that the internal structure of the first fixed seat 5 can be the same as that of the existing concentric rotating mechanism, and the internal structure of the first swing seat 6 can be the same as that of the existing eccentric structure. Thus, by improving the existing mechanical swing type balance roller, the function of the balance roller of the present utility model can be directly realized.

[0043] In a preferred embodiment of the present utility model, the first driving mechanism 8 is an electric cylinder or a driving motor.

When the piston rod of the electric cylinder is extended or retracted, the body of the electric cylinder can also swing, so as to ensure that the extension and retraction of the piston rod can pull or push the first swing seat 6, so that the first swing seat 6 can swing relative to the first fixed seat 5.

[0046] Since the electric cylinder can set an intermediate stop point at any position of the extension and retraction stroke of the piston rod, the first swing seat 6 can swing up and down at a certain intermediate position, so that the side end of the balance roller assembly can swing upward from the initial state and also can swing downward from the initial state, thereby realizing the adjustment of the tightness of the raw paper and the preheating cylinder.

[0047] In a preferred embodiment of the present application, the balancing roller further comprises a second driving mechanism 11; the connecting assembly 3 can comprise a second fixed seat 301 and a second swing seat 302.
