Description

Technical Field

[0001] This utility model belongs to the field of corrugated cardboard forming technology, and in particular relates to a quick-change mechanism for corrugated cardboard rolls. Background Technology

[0002] A corrugating machine is the core equipment in the manufacture of corrugated cardboard. Its working principle involves shaping flat base paper into wavy corrugations using high temperature and pressure. It typically consists of a series of precisely matched corrugating rollers. As the base paper passes through these interlocking, large rollers, it is pressed into uniform corrugations of a specific flute shape. Subsequently, an adhesive applicator precisely applies adhesive to the crests of the corrugations, and under the action of pressure rollers, it is firmly bonded to the face paper, ultimately forming multi-layered corrugated cardboard with extremely strong compression resistance and cushioning properties, providing an indispensable basic material for the modern packaging industry.

[0003] The corrugated rollers of a corrugating machine need to be replaced according to the forming requirements of different batches of cardboard. Currently, the replacement requires removing the bearings at both ends of the corrugating machine from the bearing seats and then removing the power transmission gears in order to take out the corrugated rollers. This operation is cumbersome and time-consuming.

[0004] To address the aforementioned issues, this application proposes a quick-change mechanism for corrugated cardboard rolls. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figures 1-5 As shown, this utility model is a quick-change mechanism for corrugated cardboard rolls, used for replacing corrugated rolls 2 on a support 1. The support 1 is connected to pressure rolls 3 corresponding to corrugated rolls 2 via telescopic rods. Both ends of the corrugated rolls 2 are provided with transmission wheels 21 and linear slide rods 22 connected to the support 1. The quick-change mechanism includes: an adapter 4, which is installed at both ends of the corrugated rolls 2; two support sleeves 5, which are respectively fixed to the transmission wheels 21 and linear slide rods 22; a connecting pin 6, which is slidably disposed in the support sleeves 5 and axially inserted into the adapter 4; and a locking rod 7, which is radially inserted into the connecting pin 6 and screwed into the threaded hole 45 on the adapter 4.

[0033] Furthermore, the support sleeve 5 is provided with a sliding hole 51 and a sliding groove 52. The connecting pin 6 slides in the sliding hole 51. An anti-rotation block 61 is fixed on the side of the connecting pin 6 and slides in cooperation with the sliding groove 52. The adapter 4 is provided with a plug hole 41 and plugs in the connecting pin 6. An anti-rotation groove 42 is provided on the side of the plug hole 41 and plugs in the anti-rotation block 61. In this embodiment, through the cooperation of the connecting pin 6, the anti-rotation block 61, the sliding hole 51, the sliding groove 52, the plug hole 41, and the anti-rotation groove 42, the anti-rotation function can be played at the same time as the connection, ensuring the stable connection of the corrugated roller 2 on the bracket 1.

[0034] Furthermore, in order to facilitate the sliding operation of the connecting pin 6 and the connection between the connecting pin 6 and the adapter 4, a through hole 62 is provided on the connecting pin 6 and the locking rod 7 slides through it. After the locking rod 7 passes through the through hole 62, it is threadedly connected to the threaded hole 45.

[0035] Furthermore, the adapter 4 is also formed with a pressing platform 43 and a limiting platform 44. One end of the locking rod 7 is fixed with a locking pin 72, which is axially inserted into the limiting platform 44. Both the pressing platform 43 and the limiting platform 44 have openings on one side for the locking rod 7 to enter and exit. When the locking pin 72 enters the limiting platform 44, the locking pin 72 and the adapter 4 are locked in a straight axial direction to prevent the connecting pin 6 from disengaging from the adapter 4.

[0036] Furthermore, to facilitate the turning operation of the locking rod 7, a turning wheel 71 is fixed at the end of the locking rod 7 near the locking pin 72.

[0037] Furthermore, in order to create an installation space between the transmission wheel 21 and the linear slide bar 22 that is larger than the length of the corrugated roller 2, the linear slide bar 22 is horizontally sliding and rotatably connected to the corrugated roller 2. When the corrugated roller 2 is connected, the linear slide bar 22 is slid outward to increase the activity space of the corrugated roller 2, thereby facilitating the connection.

[0038] Furthermore, to ensure a stable connection between the adapter 4 and the corrugated roller 2, an adapter 201 is welded and fixed to the end of the corrugated roller 2. The adapter 201 has a polygonal recess 202. The adapter 4 is inserted into the polygonal recess 202 and fixed with bolts. Figure 3 and Figure 5 As shown, after the bolt enters the socket 41, it passes through the adapter 4 and then screws into the screw hole inside the adapter 201 to fix the adapter 4 and the adapter 201.

[0039] It is understood that this utility model designs the transmission wheel and linear slide bar at both ends of the corrugated roller as a separate structure, and connects them through an adapter, a support sleeve and a connecting pin; the connecting pin can slide in the support sleeve and be quickly inserted into the adapter, and then locked by the locking rod, which has the advantages of reliable connection and convenient operation.

[0040] One specific application of this embodiment is:

[0041] like Figure 1-3 The corrugated roller 2 is in the connected state. The disassembly of the corrugated roller 2 in this state is as follows: Use a crane or other lifting equipment to hoist the corrugated roller 2, unscrew the locking rods 7 at both ends from the threaded holes 45, keep the locking rods 7 in the insertion state with the through holes 62, slide the connecting pin 6 towards the support sleeve 5 by the screwing wheel 71, the connecting pin 6 disengages from the insertion hole 41 as it slides in the sliding hole 51, and the anti-rotation block 61 disengages from the anti-rotation groove 42 as it slides in the sliding groove 52. At this time, the corrugated roller 2 is completely disengaged from the transmission wheel 21 and the linear slide bar 22. The corrugated roller 2 is then hoisted away by the crane.

[0042] Installation of corrugated roller 2: The linear slide bar 22 slides outward on the bracket 1 to free up the axial movement space. The overhead crane lifts the corrugated roller 2 to the installation position. First connect the adapter 4, support sleeve 5, and connecting pin 6 at the connection between the corrugated roller 2 and the drive wheel 21. Then connect the linear slide bar 22 and the corrugated roller 2.

[0043] The specific connection of adapter 4, support sleeve 5, and connecting pin 6 is as follows: The connecting pin 6 is pulled towards the adapter 4 through the screw wheel 71 and locking rod 7 within the support sleeve 5. The connecting pin 6 engages with the insertion hole 41, the through hole 62 engages with the anti-rotation groove 42, and the locking rod 7 is screwed tightly after being coaxial with the threaded hole 45. The locking pin 72 enters the limiting platform 44 and presses against the pressing platform 43, thus completing the connection. After the adapter 4, support sleeve 5, and connecting pin 6 on one side of the linear slide rod 22 are connected, the linear slide rod 22 returns to its original position.
