Description

Technical Field

[0001] The invention relates to the technical field of corrugated paper production equipment, in particular to a rolling device for corrugated paper production. Background Art

[0002] The existing corrugated paper production process usually includes raw material preparation, pulp preparation, corrugated paper core forming, face paper bonding, wax coating, cutting adjustment and subsequent processing. In the corrugated paper core forming and face paper bonding process, a rolling device is usually required.

[0003] The existing rolling device usually includes a frame, and a pressure roller, an upper corrugated roller and a lower corrugated roller are arranged in the frame from top to bottom. There is a gap between the pressure roller and the upper corrugated roller, and the upper corrugated roller and the lower corrugated roller are matched and meshed. The lower corrugated roller is an active roller, and a gear is installed at the shaft end. The motor drives the lower corrugated roller to rotate through a reduction device, and the upper corrugated roller is a driven roller. The upper corrugated roller and the lower corrugated roller mesh with each other to roll and roll the base paper into a wavy corrugated paper core. After the corrugated paper core is formed, the paste is applied to one side of the corrugated paper core, so that the corrugated paper core and the face paper pass through the pressure roller and the upper corrugated roller at the same time, and the face paper and the corrugated paper core are pressed by the pressure roller, so that the face paper and the corrugated paper core are glued together.

[0004] During the use of the existing rolling device, the gap between the pressure roller and the upper corrugated roller is adjusted by a hydraulic system. However, the adjustment accuracy of some commonly used hydraulic systems is low, which can easily cause the pressure roller to apply too much or too little pressure to the face paper and the corrugated paper core. When the pressure is too high, the corrugated paper core is easily deformed by pressure, thereby affecting the final production quality of the corrugated paper; when the pressure is too low, bubbles are easily generated between the corrugated paper core and the face paper, resulting in poor fitting between the corrugated paper core and the face paper, which will also affect the final production quality of the corrugated paper. Summary of the invention

[0015] By adopting the above technical solution, when the output end of the motor rotates, the first bevel gear rotates synchronously, thereby driving the second bevel gear and the transmission rod to rotate synchronously under the meshing action. When the transmission rod rotates, it helps to drive the third bevel gear to rotate synchronously, which in turn helps to drive the connecting bevel gear to rotate under the meshing action, which helps to drive the two threaded rods to rotate synchronously, thereby helping to drive the two connecting seats to rise and fall synchronously in the movable cavity, which helps to adjust the position of the pressure roller in the vertical direction, that is, it helps to adjust the gap between the pressure roller and the upper corrugated roller, which helps to avoid the compression deformation of the corrugated paper core while ensuring the bonding effect of the corrugated paper core and the face paper, thereby ensuring the final production quality of the corrugated paper.

[0036] Reference Figure 1 The driving assembly 5 includes a driving motor 51, a reducer 52, a driving gear 53 and a driven gear 54. The driving motor 51 and the reducer 52 are fixedly mounted on the outer wall of the frame 1, and the output end of the driving motor 51 is fixedly connected to the input end of the reducer 52. The driving gear 53 is fixedly mounted on the output end of the reducer 52. The driven gear 54 is fixedly sleeved on the roller shaft of the lower corrugated roller 4, and the driven gear 54 is meshed with the driving gear 53.

[0037] Reference Figure 1 The driving motor 51 is operated, and the driving gear 53 is driven to rotate through the speed reducer 52, thereby driving the driven gear 54 to rotate under the meshing action, and then driving the lower corrugating roller 4 to rotate synchronously. When the lower corrugating roller 4 rotates, the upper corrugating roller 3 is rotated at the same time under the meshing action, so that the base paper passing through the upper corrugating roller 3 and the lower corrugating roller 4 is rolled into a corrugated paper core.

[0038] Reference Figure 1 and Figure 2 , a pasting assembly 6 is arranged inside the frame 1, and the pasting assembly 6 includes a placing box 61, a paste scraping roller 62 and a coating roller 63. The placing box 61 is fixedly mounted on the inner wall of the frame 1, and paste is placed inside the placing box 61. The paste scraping roller 62 is rotatably mounted on the inner wall of the frame 1 and the bottom of the paste scraping roller 62 is located inside the placing box 61. The coating roller 63 is rotatably mounted on the inner wall of the frame 1, and the paste scraping roller 62 and the upper corrugated roller 3 are arranged tangentially to the coating roller 63. A paste scraping plate 18 is fixedly mounted inside the placing box 61, and the paste scraping plate 18 is arranged close to the surface of the paste scraping roller 62 on the side away from the placing box 61.

[0039] Reference Figure 1 and Figure 2 When the upper corrugating roller 3 rotates, the coating roller 63 rotates synchronously under the drive of the upper corrugating roller 3, thereby driving the paste scraping roller 62 to rotate synchronously. The paste scraping roller 62 will adhere the paste in the box 61 to its own surface while rotating, and the remaining paste will adhere to the coating roller 63 after being scraped off by the paste scraping plate 18, and then the coating roller 63 will apply the paste to the surface of the corrugated paper core.

[0040] Reference Figure 1When the corrugated paper core is formed, it will pass through the gap between the pressure roller 2 and the upper corrugated roller 3 under the drive of the upper corrugated roller 3. At the same time, the operator makes the face paper pass through the gap between the pressure roller 2 and the upper corrugated roller 3 at the same time, and uses the pressure roller 2 to roll the face paper and the corrugated paper core, which helps to make the corrugated paper core and the face paper fit together.

[0041] Reference Figure 1 and Figure 2 A plurality of slots 15 are provided on the circumference of the upper corrugating roller 3, and the plurality of slots 15 are arranged at intervals along the axial direction of the upper corrugating roller 3. A mounting rod 16 is fixedly installed on the side of the upper corrugating roller 3 in the frame 1 away from the placement box 61, and the axis of the mounting rod 16 is parallel to the axis of the upper corrugating roller 3, and a plurality of inserts 17 are fixedly installed on the mounting rod 16 along its own axial direction at intervals, and each insert 17 is correspondingly inserted into a slot 15.

[0042] Reference Figure 1 and Figure 2 After the corrugated paper core and the face paper are rolled by the pressure roller 2, the corrugated paper core continues to move under the drive of the upper corrugated roller 3, and is separated from the upper corrugated roller 3 under the action of multiple inserts 17, which helps to ensure the consistency of the moving paths of the corrugated paper core and the face paper, thereby helping to improve the gluing and bonding effect of the corrugated paper core and the face paper, and ensuring the final production quality of the corrugated paper.

[0043] Reference Figure 3 and Figure 4 The frame 1 is provided with an adjustment mechanism, which includes two connecting seats 7. Active cavities 8 are vertically opened on the two opposite inner side walls of the frame 1. Each connecting seat 7 can be lifted and placed in an active cavity 8, and each connecting seat 7 is rotatably connected to the roller shaft end of the pressure roller 2. A threaded rod 9 is vertically rotatably installed in each active cavity 8, and the threaded rod 9 passes through the connecting seat 7. A mounting cavity 10 connected to the active cavity 8 is horizontally opened on the top of the frame 1, and a synchronous transmission component 11 is arranged inside the mounting cavity 10.

[0044] Reference Figure 3 and Figure 4The synchronous transmission assembly 11 includes an electric push rod 111, a connecting block 112, a clamping block 113, a connecting rod 114, a worm wheel 115 and a worm 116. The worm wheel 115 is fixedly sleeved on the circumference of the threaded rod 9 and is located inside the installation cavity 10. The worm 116 is horizontally rotatably installed inside the installation cavity 10 and meshes with the worm wheel 115. The electric push rod 111 is fixedly installed on the top surface of the frame 1, and the output end of the electric push rod 111 is inserted downward into the installation cavity 10. In this embodiment, the connecting block 112 is T-shaped, and the connecting block 112 is fixedly connected to the output end of the electric push rod 111. The top end of the clamping block 113 is slidably clamped with the connecting block 112, and the bottom end of the clamping block 113 is hinged with the connection. The end of the connecting rod 114 away from the clamping block 113 is fixedly connected to the worm 116.

[0045] Reference Figure 3 and Figure 4 The operator starts the electric push rod 111, and uses the output end of the electric push rod 111 to drive the connecting block 112 to rise and fall, so that the clamping block 113 slides horizontally on the connecting block 112 as the connecting block 112 rises and falls, and the clamping block 113 drives the connecting rod 114 to rotate while sliding, so that the worm 116 rotates; the worm 116 drives the worm wheel 115 and the threaded rod 9 to rotate while rotating, thereby driving the two connecting seats 7 to rise and fall synchronously in their respective active cavities 8, thereby adjusting the position of the pressure roller 2 in the vertical direction, which helps to adjust the gap between the pressure roller 2 and the upper corrugated roller 3, thereby helping to avoid the compression deformation of the corrugated paper core while ensuring the bonding effect of the corrugated paper core and the face paper, thereby helping to ensure the final production quality of the corrugated paper.

[0046] Reference Figure 5 The circumferential outer ring of the pressure roller 2 is sleeved with a buffer sleeve 12, and a plurality of mounting blocks 13 are integrally formed on the circumferential inner wall of the buffer sleeve 12. A plurality of mounting slots 14 are provided on the circumferential outer wall of the pressure roller 2, and the groove depth of the mounting slots 14 is greater than the height of the mounting blocks 13. The buffer sleeve 12 helps to play a buffering role, thereby helping to further ensure the lamination effect of the corrugated paper core and the face paper while preventing the corrugated paper core from being compressed and deformed, further ensuring the final production quality of the corrugated paper.

[0047] The implementation principle of the embodiment of the present application is as follows: the driving motor 51 is running, and the driving gear 53 is driven to rotate through the reducer 52, thereby driving the driven gear 54 to rotate under the meshing action, and then driving the lower corrugating roller 4 to rotate synchronously. When the lower corrugating roller 4 rotates, the upper corrugating roller 3 is caused to rotate at the same time under the meshing action, so that the base paper passing through the upper corrugating roller 3 and the lower corrugating roller 4 is rolled into a corrugated paper core in a wavy shape.

[0048] When the upper corrugating roller 3 rotates, the coating roller 63 rotates synchronously under the drive of the upper corrugating roller 3, thereby driving the paste scraping roller 62 to rotate synchronously. The paste scraping roller 62 will adhere the paste in the box 61 to its own surface while rotating, and the remaining paste will adhere to the coating roller 63 after being scraped off by the paste scraping plate 18, and then the coating roller 63 will apply the paste to the surface of the corrugated paper core.

[0049] After the corrugated paper core is formed, it will pass through the gap between the pressure roller 2 and the upper corrugated roller 3 under the drive of the upper corrugated roller 3. At the same time, the operator makes the face paper pass through the gap between the pressure roller 2 and the upper corrugated roller 3 at the same time, and uses the pressure roller 2 to roll the face paper and the corrugated paper core, which helps to make the corrugated paper core and the face paper fit together.

[0050] After the corrugated paper core and the face paper are rolled by the pressure roller 2, the corrugated paper core continues to move driven by the upper corrugated roller 3, and is separated from the upper corrugated roller 3 by the action of multiple inserts 17, which helps to ensure the consistency of the moving paths of the corrugated paper core and the face paper, thereby helping to improve the gluing and bonding effect of the corrugated paper core and the face paper, and ensuring the final production quality of the corrugated paper.

[0051] The operator starts the electric push rod 111, and uses the output end of the electric push rod 111 to drive the connecting block 112 to rise and fall, so that the clamping block 113 slides horizontally on the connecting block 112 as the connecting block 112 rises and falls, and the clamping block 113 drives the connecting rod 114 to rotate while sliding, so that the worm 116 rotates; the worm 116 drives the worm wheel 115 and the threaded rod 9 to rotate while rotating, thereby driving the two connecting seats 7 to rise and fall synchronously in their respective active cavities 8, thereby adjusting the position of the pressure roller 2 in the vertical direction, which helps to adjust the gap between the pressure roller 2 and the upper corrugated roller 3, thereby helping to avoid the compression deformation of the corrugated paper core while ensuring the bonding effect of the corrugated paper core and the face paper, thereby helping to ensure the final production quality of the corrugated paper.
