Description

Technical Field

[0001] This utility model relates to the field of corrugated roll testing technology, and in particular to a corrugated roll test paper machine. Background Technology

[0002] In the corrugated board production industry, corrugated rolls and pressure rolls are the core equipment for corrugated paper forming and lamination. Their workflow has a clear function: the corrugated paper is first pressed and ironed between the flutes of the corrugated rolls to form its shape, then adsorbed onto the flutes of the corrugated rolls, and rotated to the top of the flutes to contact the glue rollers to complete the glue application. Then it rotates to the contact point with the pressure rollers, and finally is laminated with the linerboard running in sync and dried to form a two-layer corrugated board.

[0003] The stable operation of this function places stringent requirements on the precision of the corrugated roll assembly and pressure rolls. Under actual working conditions, several conditions must be met: the contact line pressure across the entire roll width must remain consistent during roll rotation; circular runout must be ≤0.03; the formed corrugated shape must not deviate; and symmetry accuracy must reach 0.01. Therefore, whether the roll shape accuracy and corrugated shape symmetry accuracy of newly manufactured and repaired corrugated rolls and pressure roll assemblies meet the above error requirements must be tested using specialized equipment.

[0004] However, existing testing methods have significant limitations: they are difficult to simulate the actual working positions of corrugated rolls and pressure roll groups of various specifications, and cannot be tested under real working conditions of mutual pressure from hydraulic cylinders. This makes it impossible to accurately complete the accuracy test by simulating the corrugated paper's operation and forming and compound rolling on the entire sheet of carbon paper—it is difficult to judge the flute symmetry accuracy error by the spacing of the indentations on the carbon paper after the corrugated rolls are formed, and it is also impossible to use the axial indentations on the carbon paper pressed between the corrugated rolls and the pressure rolls to check the uniformity of axial pressure to judge the roll shape accuracy error.

[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0039] Please see Figures 1 to 2 As shown, this utility model provides a corrugated roll test paper machine, which includes a base 1 and a drive mechanism 2. A corrugated roll clamping mechanism 3 and a pressure roll clamping mechanism 4 are slidably arranged on the base 1, wherein:

[0040] The base 1 has a first guide rail 11 and a second guide rail 12 arranged in parallel.

[0041] The corrugated roll clamping mechanism 3 includes two first bearing seats 31 and two second bearing seats 32. The two first bearing seats 31 are slidably connected to the first guide rail 11 and are used to clamp the two ends of the lower corrugated roll. The two second bearing seats 32 are respectively hinged to the two first bearing seats 31 and are used to clamp the two ends of the upper corrugated roll. The second bearing seats 32 can swing radially relative to the first bearing seats 31 to adjust the pressure between the upper and lower corrugated rolls.

[0042] The pressure roller clamping mechanism 4 includes two sliding seats 41 and two third bearing seats 42. The two sliding seats 41 are respectively slidably mounted on the second guide rail 12 by sliders, and the sliders are fixed with stroke locking parts with bolt locking structures for positioning the sliding seats 41. The two third bearing seats 42 are respectively hinged to the two sliding seats 41 and used to clamp the two ends of the pressure roller. The third bearing seats 42 can swing radially relative to the sliding seats 41 to adjust the pressure between the pressure roller and the lower corrugated roller.

[0043] The drive mechanism 2 is located at one end of the base 1, and its drive axis is collinear with the axis of the lower corrugated roller clamped by the first bearing seat 31. The drive mechanism 2 is used to drive the lower corrugated roller to rotate.

[0044] In actual testing, the two first bearing seats 31 can move along the first guide rail 11 to adjust the distance between them to match the length of the lower corrugated roller to be tested; the two third bearing seats 42 can move along the second guide rail 12 to adjust the distance between them to match the length of the corresponding pressure roller; the two ends of the upper corrugated roller are rotatably mounted on the two second bearing seats 32 via bearings, the two ends of the lower corrugated roller are rotatably mounted on the two first bearing seats 31 via bearings, and the two ends of the pressure roller are rotatably mounted on the two third bearing seats 42 via bearings. The bearing seat 32 oscillates radially to press the upper corrugated roller against the lower corrugated roller, and the third bearing seat 42 oscillates radially to press the pressure roller against the lower corrugated roller. The drive mechanism 2 drives the lower corrugated roller to rotate, thereby driving the upper corrugated roller and the pressure roller to rotate. This simulates the corrugated paper operation and composite rolling of the entire copy paper. The spacing of the indentations on the copy paper after being formed between the corrugated rollers is detected to determine the symmetry accuracy error of the corrugated roller profile. The uniformity of the axial indentations on the copy paper pressed between the corrugated roller and the pressure roller is checked to determine the roll profile accuracy error of each roller.

[0045] This corrugated roll testing machine, through the sliding first bearing seat 31 and third bearing seat 42, can perform precision testing on corrugated rolls and pressure roll groups of different lengths and specifications. By the radial swing of the second bearing seat 32 and third bearing seat 42, the pressure between the upper and lower corrugated rolls and the pressure roll and the lower corrugated roll can be adjusted, accurately simulating the actual working state of the corrugated rolls and pressure roll groups. It can accurately detect the flute symmetry accuracy and roll shape accuracy by means of carbon paper indentation, solving the problems of poor adaptability, difficulty in simulating actual conditions and inaccurate accuracy testing of existing testing methods.

[0046] Please see Figures 1 to 2 As shown, the base 1 has a first working surface 13 and a second working surface 14 with different heights. A first guide rail 11 is fixedly mounted on the first working surface 13, and a second guide rail 12 is fixedly mounted on the second working surface 14. The height of the first working surface 13 is greater than the height of the second working surface 14. In this embodiment, the base 1 is formed by welding a metal plate and a profile.

There are two second guide rails 12, which are arranged parallel to each other on the second working surface 14. By setting the height of the first working surface 13 to be greater than the height of the second working surface 14, a height difference is created between the pressure roller and the lower corrugated roller, simulating the actual working position arrangement of the corrugated roller and pressure roller assembly.

[0047] Please see Figures 1 to 2 As shown, the first bearing housing 31 is provided with a first clamping groove 311, which is a semi-circular groove. The first bearing housing 31 is connected to a first clamping member 33 that is adapted to the first clamping groove 311. The first clamping member 33 and the first bearing housing 31 work together to rotate and install the end of the lower corrugated roller in the first clamping groove 311. In this embodiment, the bottom of the first bearing housing 31 is slidably connected to the second guide rail 12 by several sliders, and the sliders are fixed with a travel locking member with a bolt locking structure for positioning the first bearing housing 31.

[0049] Please see Figures 1 to 2 As shown, a first bracket 35 is provided on the first bearing housing 31, and a first driving member 36 is mounted on the first bracket 35. The end of the first driving member 36 is hinged to the second bearing housing 32 and is used to drive the second bearing housing 32 to swing radially relative to the first bearing housing 31, thereby causing the upper corrugated roller clamped by the second bearing housing 32 to move closer to or away from the lower corrugated roller clamped by the first bearing housing 31. In this embodiment, the first bracket 35 is fixed to the first bearing housing 31 by bolts and is located on the side of the second bearing housing 32 away from the first clamping groove 311. The first driving member 36 is connected to the first bracket 35 by a hinge shaft and can swing relative to the first bracket 35. The first driving member 36 is a hydraulic cylinder. By driving the second bearing housing 32 to swing radially by the first driving member 36, the pressure between the upper and lower corrugated rollers is adjusted without the need for manual pressure application, saving labor and improving adjustment accuracy.

[0050] In some other embodiments, the first bracket 35 and the first bearing seat 31 are an integral structure, and the first drive member 36 may also be a linear motor 21.

[0051] Please see Figures 1 to 2As shown, the third bearing housing 42 is provided with a third clamping groove 421, which is a semi-circular groove.

The diameter of the third clamping groove 421 is the same as the diameter of the first clamping groove 311. The third clamping member 43 has the same structure as the first clamping member 33 and is fixedly connected to the third bearing housing 42 by bolts. The diameter of the third clamping groove 421 adopts the largest assembly diameter among commonly used pressure rollers. When inspecting corrugated rollers of different specifications, the installation of the corresponding pressure roller can be adapted by replacing bearings with different diameter settings.

[0052] Please see Figures 1 to 2 As shown, a second bracket 44 is provided on the sliding seat 41, and a second driving member 45 is mounted on the second bracket 44. The end of the second driving member 45 is hinged to a third bearing seat 42 and is used to drive the third bearing seat 42 to swing radially relative to the sliding seat 41, so that the pressure roller moves closer to or away from the lower corrugated roller. In this embodiment, the second bracket 44 is fixed to the sliding seat 41 by bolts and is located on the side of the third bearing seat 42 away from the first bearing seat 31. The second driving member 45 is connected to the second bracket 44 by a hinge shaft and can swing relative to the second bracket 44. The second driving member 45 is a hydraulic cylinder. By driving the third bearing seat 42 to swing radially by the second driving member 45, the pressure between the pressure roller and the lower corrugated roller is adjusted. No manual pressure application is required, saving labor and improving adjustment accuracy.

[0053] In some other embodiments, the second bracket 44 and the sliding seat 41 are an integral structure, and the second drive member 45 may also be a linear motor 21.

[0054] Please see Figure 1 As shown, the drive mechanism 2 includes a motor 21 and a clamping chuck 22. The motor 21 drives the clamping chuck 22, which clamps one end of the lower corrugated roller and drives it to rotate along its own axis. In this embodiment, the motor 21 is fixedly mounted by a mounting bracket, and the height of the drive shaft of the motor 21 is the same as the center height of the first clamping groove 311, thereby enabling the motor 21 to drive the lower corrugated roller to rotate stably. The clamping chuck 22 is a three-jaw chuck or a four-jaw chuck, and is driven by a universal joint (not shown in the figure) to drive the drive shaft of the motor 21. This allows the clamping chuck 22 to keep the motor shaft and the lower corrugated roller axis coaxial regardless of the diameter of the lower corrugated roller being clamped, thus ensuring stable rotation. By radially clamping one end of the lower corrugated roller by the clamping chuck 22, the purpose of the motor 21 driving the lower corrugated roller to rotate is achieved.

[0055] In this embodiment, an electrical control box (not shown in the figure) is also included. The electrical control box is preferably a PLC-controlled electrical control box. The electrical control box is electrically connected to the first drive unit 36, the second drive unit 45 and the motor 21 respectively, and flexibly controls the pressure of the first drive unit 36 ​​and the second drive unit 45 on the swing of the second bearing seat 32 and the third bearing seat 42, as well as the speed adjustment of the motor 21, so as to adapt to the simulation detection requirements of roller groups of different specifications.

[0056] Please see Figures 1 to 2 As shown, the corrugated roll clamping mechanism 3 also includes a first gear 37 and a second gear 38 that mesh with each other. The first gear 37 is fixedly connected to the first bearing seat 31 by bolts and is coaxial with the hinge axis of the first bearing seat 31 and the second bearing seat 32. The second gear 38 is fixed to the second bearing seat 32 by bolts. In this embodiment, both the first gear 37 and the second gear 38 are located outside the second bearing seat 32. When the second bearing seat 32 swings radially relative to the first bearing seat 31, the second gear 38 rotates around the first gear 37. Thus, by changing the meshing position of the second gear 38 on the first gear 37, the radial swing angle of the second bearing seat 32 can be precisely adjusted, thereby achieving precise adjustment of the pressure of the upper corrugated roll on the lower corrugated roll.

[0057] Please see Figures 1 to 2 As shown, the pressure roller clamping mechanism 4 also includes a third gear 46 and a fourth gear 47 that mesh with each other. The third gear 46 is fixedly connected to the sliding seat 41 by bolts and is coaxial with the hinge axis of the sliding seat 41 and the third bearing seat 42. The fourth gear 47 is fixed to the third bearing seat 42 by bolts. In this embodiment, both the third gear 46 and the fourth gear 47 are located outside the third bearing seat 42. When the third bearing seat 42 swings radially relative to the sliding seat 41, the fourth gear 47 rotates around the third gear 46. Thus, by changing the meshing position of the fourth gear 47 on the third gear 46, the radial swing angle of the third bearing seat 42 can be precisely adjusted, thereby achieving precise adjustment of the pressure of the pressure roller on the lower corrugated roller.
