Description

TECHNICAL FIELD

[0001] The utility model mainly relates to corrugated paperboard production technical field, concretely relates to a balance roller for corrugated paperboard production line. BACKGROUND

[0002] In the production process of corrugated paper, the balance roller on the corrugated paper production equipment is an indispensable important structure, mainly has the functions of adjusting tension, guaranteeing adhesion, controlling thickness, buffering and damping, and stabilizing conveying.

[0003] The balance roller can adjust the paper path and wrapping angle of the corrugated paper by adjusting its position or angle, so as to adjust the tension of the corrugated paper. When the balance roller is matched with other rollers, the pressure can be automatically or manually adjusted according to the thickness and material of the corrugated paper, so that the glue can be uniformly coated on the surface of the paper, and the adhesion quality between the layers of paper is guaranteed. In addition, the balance roller can also control the thickness of the corrugated paperboard to a certain extent. By adjusting the gap between the balance roller and other rollers, appropriate pressure is applied to the corrugated paperboard. The balance roller also has the function of guiding the corrugated paperboard to be conveyed along the predetermined path, preventing the paper from deviating or shaking during conveying, ensuring the continuity and stability of the production process, and improving the production efficiency.

[0004] The inventor found the following defects in the specific implementation process:

[0005] In actual use, the balance roller is usually of an integrated structure, and is erected on the corrugated paper production equipment. Position degree adjusting devices are arranged at both ends of the balance roller. The ordinary adjusting device is usually manually adjusted and controlled, and the adjusting precision is low. This may cause uneven pressure on the roller surface, so that when adjusting the tension of the paper or controlling the thickness of the paperboard, the local pressure may be too large or too small, which causes the tension of the paper on the surface to be inconsistent, resulting in overall deformation of the corrugated paper, affecting the flatness and quality of the paperboard. If a high-precision automatic adjusting device is used, the equipment space is occupied, and the equipment cost is high.

[0006] It should be noted that the above content belongs to the technical cognition of the inventor. Since the technical content in this field is vast and complex, the above content of the present application does not necessarily constitute the prior art. UTILITY MODEL CONTENT

One end of the telescopic balance rod 6 is in contact with the inner wall of the roller 1. The correction mechanism 4 includes multiple levers 401, and a rotary cylinder 402 is provided on one side of the levers 401.

[0031] See attached document Figures 1-4 The positioning end 3 includes an adjusting plate 301 and a positioning plate 302. The adjusting plate 301 and the positioning plate 302 are fixedly connected by multiple guide rods. The correction mechanism 4 is located between the adjusting plate 301 and the positioning plate 302 and is connected to the adjusting plate 301. The positioning end 3 is fixedly connected to the roller 1. The positioning end 3 is assembled with the production equipment through the positioning plate 302 and the guide shaft 5. The adjusting plate 301 has a central hole 3011. One end of the spindle 2 passes through the central hole 3011. Multiple levers 401 are arranged in a circumferential array along the central hole 3011. The spindle 2 passes through the central hole 3011 and protrudes from the multiple levers 401.

[0032] See attached document Figures 1-4 There are three paddles 401, which are rotatably connected to the adjusting disk 301 via a rotating shaft. One end of each paddle 401 has external teeth 4011, which mesh with a drive gear 403. The drive gear 403 drives the paddles 401 to rotate. The end of each paddle 401 away from the external teeth 4011 is in contact with the outer wall of the spindle 2. The paddles 401 are curved and gradually become smaller at the end near the spindle 2. The paddles 401 are generally shaped like a curved knife. The drive end of the rotary cylinder 402 is connected to the drive gear 403, which meshes with the external teeth 4011. The drive gear 403 is rotatably connected to the adjusting disk 301 via a rotating shaft. After the rotary cylinder 402 is started, the drive gear 403 rotates, causing the paddles 401 to rotate around the rotating shaft as a fulcrum, which is used to paddle the spindle 2.

[0033] See attached document Figures 1-4Multiple sets of telescopic balance rods 6 are welded to the spindle 2 at one end. The telescopic balance rods 6 are hydraulic telescopic rods. After the spindle 2 swings through the correction mechanism 4 at both ends, the multiple sets of telescopic balance rods 6 swing and extend with the spindle 2 to control the position and angle of the roller 1.

[0034] In this embodiment, the swing angle of the spindle 2 is adjusted by the correction mechanism 4 set at both ends of the roller 1. After the spindle 2 swings, multiple sets of telescopic balance bars 6 drive the roller 1 to adjust its position and angle. The roller 1 is not restricted by the assembly between the balance roller and the production equipment, and can be flexibly adjusted to improve the convenience of use and increase production efficiency.
