Description

Technical Field

[0001] This application relates to the field of corrugated board production technology, and in particular to a corrugated board production equipment. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper and one layer of cardboard. Due to its high mechanical strength, it can withstand collisions and drops during handling. Moreover, it has low production costs, is recyclable, energy-saving and environmentally friendly, and is therefore widely used in the production of various packaging cartons.

[0003] Currently, corrugated cardboard production equipment typically includes a base paper loading assembly, a laminating machine, a bonding machine assembly, a slitting and creasing machine, a cross-cutting machine, longitudinal and transverse paper feeders, and a stacking machine. The laminating machine is the core of the production equipment, used to form the corrugations on the cardboard. It mainly includes a frame, multiple sets of concave and convex pressure rollers, and a drive device to rotate the pressure rollers. When pressing the base paper into corrugations, the base paper is first preheated by the loading assembly, with humidity, temperature, and tension adjusted. It then enters the preheater for a second adjustment of humidity, temperature, and tension. Finally, the drive device drives two concave and convex pressure rollers in each set to continuously heat-roll the base paper at high temperature. The corrugated paper is formed. In corrugated paper laminators, multiple sets of concave and convex pressure rollers are usually fixedly installed. That is, although the two ends of the concave and convex pressure rollers are rotatably connected to the frame, the connection is fixed by welding or integral molding. In actual production, it is necessary to roll corrugated paper of different thicknesses according to order requirements. Therefore, it is necessary to adjust the spacing between the two concave and convex pressure rollers in each set. However, because the concave and convex pressure rollers are usually fixedly installed, it is difficult for the staff to remove them non-destructively when replacing them. Moreover, the disassembly and replacement process is very complicated. Therefore, corrugated paper laminators are only suitable for paper of the same thickness and have low practicality and applicability. Summary of the Invention

[0004] To facilitate the quick and non-destructive replacement of the concave and convex pressure rollers by staff, thereby enabling the rolling of base paper of different thicknesses according to order requirements and improving the practicality and applicability of the corrugated board laminating machine, this application provides a corrugated board production equipment.

[0005] This application provides a corrugated cardboard production equipment, which adopts the following technical solution:

[0006] A corrugated cardboard production equipment includes a corrugated board laminating machine body and a mounting frame disposed on the corrugated board laminating machine body. The mounting frame includes a bottom support, two intermediate mounting plates that abut against the bottom support and are spaced apart, and a top mounting plate that abuts against the intermediate mounting plates.

[0007] A drive roller is provided between the intermediate mounting plate and the bottom bracket and the top mounting plate, and a driven roller is provided on the bottom bracket and between the two top mounting plates. The two drive rollers correspond one-to-one with the two driven rollers.

[0008] It also includes two drive gears respectively fitted onto the ends of the drive rollers, a quick-release mechanism disposed between the tile mounting machine body and the mounting frame for moving the mounting frame to the outside of the tile mounting machine body and quickly separating the middle mounting plate and the top mounting plate along the height direction, and for quickly connecting or separating the drive gears from the ends of the drive rollers, and a drive mechanism detachably connected between the tile mounting machine body and one of the drive gears for driving the drive gears to rotate, wherein the two drive gears mesh with each other.

[0009] By adopting the above technical solution, when workers roll the base paper into corrugated sheets using production equipment, the base paper is first preheated by the paper feeding assembly, and the humidity, temperature, and tension are adjusted. Then, it enters the preheater for a second adjustment of humidity, temperature, and tension. Finally, under the rolling action of the drive roller and driven roller, it can be continuously hot-rolled into corrugated paper. When workers need to roll base paper of different thicknesses, they first disconnect the drive mechanism from the drive gear. Then, using the quick-release mechanism, they move the mounting frame and the drive roller and driven roller mounted on the mounting frame to the outside of the corrugated sheet machine body, and remove the drive gear from the end of the drive roller. Subsequently, the workers again use the quick-release mechanism to move the top mounting plate and the middle mounting plate on the mounting frame upwards to the bottom support. Separate and replace the two drive rollers from top to bottom with drive rollers of a thickness suitable for the thickness of the base paper. Then, the operator moves the mounting frame and drive rollers back into the body of the corrugated sheet machine using the quick-release mechanism, installs the drive gear to the end of the drive roller, and finally connects the drive mechanism to the drive gear to complete the quick replacement of the drive rollers. When the operator needs to roll base paper of different thicknesses, the quick-release mechanism can be used to quickly move the mounting frame and drive rollers to the outside of the corrugated sheet machine body and quickly separate the multiple connecting parts used to fix the drive rollers, thereby achieving non-destructive removal and replacement of the drive rollers. This simplifies the disassembly and replacement process, making it easier for the operator to roll base paper of different thicknesses according to order requirements, and improving the practicality and applicability of the corrugated sheet machine.

[0010] Optionally, the mobile quick-installation mechanism includes bearings disposed at both ends of the drive roller along its length, bearing holders disposed on the mounting frame for supporting and fixing the bearings, a horizontal moving component disposed between the tile mounting machine body and the mounting frame for driving the mounting frame to move outward from the tile mounting machine body, a separating component disposed between the bottom support and the top mounting plate for moving the middle mounting plate and the top mounting plate up and down, a fixing component disposed between the bottom support, the middle mounting plate, and the top mounting plate for fixing the three, and a connecting component disposed between the drive gear and the end of the drive roller for connecting the drive gear and the drive roller.

[0011] By adopting the above technical solution, when replacing the drive roller using the quick-release mechanism, the operator first moves the mounting frame to the outside of the laminating machine body using the horizontal moving component. Then, the operator disconnects the drive gear from the drive roller using the connecting component, and disconnects the bottom support, top mounting plate, and middle mounting plate using the fixing component. Subsequently, the operator separates the top mounting plate from the middle mounting plate and the middle mounting plate from the bottom support in sequence using the separating component. Finally, the operator removes the two drive rollers from top to bottom and replaces them with drive rollers of a thickness that matches the thickness of the original paper, thus completing the replacement of the drive roller. The operator can quickly disassemble and replace the drive roller through the cooperation of the horizontal moving component, separating component, fixing component, and connecting component. The fixing component makes the bottom support, middle mounting plate, and top mounting plate form a whole, making the subsequent operation of the drive roller less prone to shaking and more stable. The horizontal moving component moves the mounting frame to the outside of the laminating machine body, making it easier for the operator to operate.

[0012] Optionally, the separation assembly includes two drive rods vertically arranged in the mounting frame, a support plate fixed to the top of the drive rods, a top support plate fixed in the top mounting plate, an intermediate support plate fixed in the middle mounting plate, a bottom support plate fixed in the bottom bracket, two first screws and second screws respectively sleeved on the outside of the drive rods, a connecting sleeve slidably sleeved on the outside of the drive rods, a first connecting block fixed above the connecting sleeve, a second connecting block fixed below the connecting sleeve, a linkage component disposed between the two drive rods for driving the two drive rods to rotate synchronously, a transmission motor disposed between one of the drive rods and the mounting frame, a transmission gear set disposed between the output shaft of the transmission motor and the drive rod, and a moving component disposed between the connecting sleeve and the mounting frame for driving the connecting sleeve to move up and down.

[0013] The top support plate, middle support plate, and bottom support plate are all sleeved on the outside of the drive rod, and the bottom support plate is rotatably connected to the drive rod; the top of the first screw is rotatably connected to the support plate, and the first screw is threadedly connected to the top support plate; the bottom of the second screw is rotatably connected to the bottom support plate, and the second screw is threadedly connected to the middle support plate.

[0014] The connecting sleeve is located between the first screw and the second screw. The first screw has a first connecting hole at its bottom. The first connecting block can be inserted into and attracted into the first connecting hole and cannot rotate relative to the first connecting hole. The second screw has a second connecting hole at its top. The second connecting block can be inserted into and attracted into the second connecting hole and cannot rotate relative to the second connecting hole.

[0015] By adopting the above technical solution, when the two top mounting plates in the mounting frame are moved upward by separating the components, the worker first moves the connecting sleeve upward by moving the moving part. Then, the connecting sleeve moves the first connecting block into the first connecting hole at the bottom of the first screw. Subsequently, the worker starts the drive motor, which drives the drive rod to rotate. The drive rod drives the connecting sleeve and the first connecting block, which are slidably connected to it, to rotate. The first connecting block drives the first screw to rotate, which in turn drives the top support plate and the top mounting plate downward, thereby opening the bearing holder between the top mounting plate and the middle mounting plate. Then, the worker replaces the drive roller and the bearing at the end of the drive roller located between the top mounting plate and the middle mounting plate. After the drive roller between the top mounting plate and the middle mounting plate is replaced, the worker moves the connecting sleeve to move the second connecting block into the second connecting hole at the top of the second screw by moving the moving part. At this time, the first connecting block separates from the first connecting hole. Then, the worker... The operator starts the drive motor, which drives the drive rod, the second connecting block, and the second screw to rotate. The second screw drives the middle support plate and the middle mounting plate to move upward, thereby opening the bearing holder between the middle mounting plate and the bottom bracket. Then, the operator can replace the drive roller and the bearing at the end of the drive roller located between the middle mounting plate and the bottom bracket. The top mounting plate and the middle mounting plate are relatively heavy. The separation component allows the top mounting plate to be separated from the middle mounting plate and the middle mounting plate from the bottom bracket in sequence, which is convenient and does not require manual handling. Then, the linkage component can realize the synchronous rotation of the drive rollers on both sides of the mounting frame, so that the two top mounting plates and the two middle mounting plates on the two mounting frames move up and down synchronously, making the operation of the operator more convenient. Secondly, the operator can control the connection between the connecting sleeve and the first screw or the second screw through the moving component, thereby realizing the separation of the top mounting plate and the middle mounting plate through a single drive motor, making the overall structure of the tile mounting machine more compact.

[0016] Optionally, the moving component includes a moving plate rotatably sleeved on the outside of the connecting sleeve and a moving rod fixed on one side of the moving plate; the mounting frame has a moving groove along its height direction, and one end of the moving rod passes through the moving groove and is located on the outside of the mounting frame.

[0017] By adopting the above technical solution, when the moving plate and the connecting sleeve are rotatably connected, and the driving rod drives the connecting sleeve to rotate, it will not drive the moving plate and the moving rod to rotate, so that the moving plate and the moving rod are less likely to interfere with the rotation of the connecting sleeve.

[0018] Optionally, the linkage component includes two sprockets respectively fixedly sleeved on two drive rods, and a chain disposed in the mounting frame and meshing with both sprockets.

[0019] By adopting the above technical solution, the sprocket and chain can not only achieve synchronous rotation of the two drive rods, but also have high assembly precision, so that when the two drive rods rotate synchronously, slippage and asynchrony are less likely to occur, thereby improving the stability of the mobile quick-assembly mechanism.

[0020] Optionally, the horizontal moving assembly includes a moving block that slides vertically to one side of one of the top mounting plates, a drive screw that rotates horizontally to the tile mounting machine body, and a drive motor disposed at one end of the drive screw.

[0021] The top mounting plate has a vertical groove for movement, the moving block slides within the vertical groove, and the drive screw is threadedly connected to the moving block.

[0022] By adopting the above technical solution, when the mounting frame is moved horizontally by the horizontal moving component, the operator first starts the drive motor, then the drive motor drives the drive screw to rotate, the drive screw drives the moving block to move horizontally, and the moving block can drive the mounting frame to move horizontally; wherein the moving block not only applies a horizontal thrust to the mounting frame, but also can move up and down in the sliding groove on the top mounting plate in the vertical direction, so that the subsequent movement of the top mounting plate in the vertical direction is not affected.

[0023] Optionally, the drive motor is a brake motor.

[0024] By adopting the above technical solution, the brake motor can lock the drive screw after power failure, making the drive screw less prone to self-rotation due to vibration and other factors, thereby improving the stability of the tile mounting machine operation.

[0025] Optionally, the connecting assembly includes a connecting disc abutting against the side of the drive gear away from the drive roller, a plurality of connecting bolts threaded between the connecting disc and the drive gear, a plurality of plug rods fixed on the side of the connecting disc near the drive roller, and a plurality of anti-disengagement bolts threaded between the connecting disc and the end of the drive roller; the end of the drive roller is provided with a plug groove adapted to the plug rod, and the plug rod is inserted into the plug groove.

[0026] By adopting the above technical solution, when disconnecting the drive gear from the end of the drive roller through the connecting assembly, the operator first loosens and removes multiple anti-detachment bolts to disconnect the connection between the connecting plate and the end of the drive roller. Then, the connecting plate is moved away from the drive roller, and the connecting plate can drive the plug rod to disengage from the plug slot, thereby realizing the disassembly of the drive gear; conversely, the connection between the drive gear and the end of the drive roller can be realized. The connecting bolt enables the detachable connection between the drive gear and the connecting plate, so that when the drive gear wears out after long-term operation, it is convenient for the operator to replace the drive gear.

[0027] Optionally, the fixing component includes a connecting ring that simultaneously abuts against one side of the bottom bracket, the middle mounting plate, and the top mounting plate, a plurality of fixing bolts disposed between the connecting ring and the mounting frame, and a plurality of positioning blocks fixed on the side of the connecting ring near the mounting frame. The mounting frame has a positioning groove, and the positioning blocks are inserted into the positioning groove.

[0028] By adopting the above technical solution, when fixing the bottom bracket, middle mounting plate and top mounting plate in the mounting frame through the fixing components, firstly, the positioning block on the connecting ring is inserted into the positioning groove, and then the connecting ring is fixed to one side of the mounting frame by fixing bolts. This makes the bottom bracket, middle mounting plate and top mounting plate form a whole, thereby firmly fixing the end of the drive roller, making it less likely to shake when the drive roller is running, and improving the stability of the tile mounting machine.

[0029] Optionally, the drive mechanism includes a gear shaft rotatably connected to one side of the mounting frame, a power motor disposed on one side of the tile mounting machine body, a gearbox disposed between the power motor and the gear shaft, and a coupling disposed between the output shaft of the gearbox and the end of the gear shaft; the gear shaft meshes with the drive gear.

[0030] By adopting the above technical solution, when the drive mechanism drives the drive gear to rotate, the operator first starts the power motor. The power motor converts the power through the gearbox to drive the gear shaft to rotate, and the gear shaft can drive the drive gear to rotate. The gearbox can adjust the speed of the drive gear, so as to meet the required rolling speed when rolling paper of different thicknesses, and improve the quality of the paper after corrugation. At the same time, the operator can quickly connect or disconnect the gear shaft from the output shaft of the gearbox through the coupling.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. When workers need to roll paper of different thicknesses, the quick-release mechanism can be used to quickly move the mounting frame and drive roller to the outside of the corrugated board machine body, and quickly separate the multiple connecting parts used to fix the drive roller, thereby realizing the non-destructive removal and replacement of the drive roller, simplifying the disassembly and replacement process, making it easier for workers to roll paper of different thicknesses according to order requirements, and improving the practicality and applicability of the corrugated board machine.

[0033] 2. In the mobile quick-installation mechanism, the operator can quickly disassemble and replace the drive roller through the cooperation of the horizontal moving component, the separating component, the fixing component, and the connecting component. The fixing component makes the bottom support, the middle mounting plate, and the top mounting plate form a whole, which makes the subsequent operation of the drive roller less prone to shaking and more stable. The horizontal moving component moves the mounting frame to the outside of the tile mounting machine body, which makes it easier for the operator to operate.

[0034] 3. The top mounting plate and middle mounting plate are relatively heavy. The separation component allows the top mounting plate to be separated from the middle mounting plate, and the middle mounting plate to be separated from the bottom support in sequence. The operation is convenient and does not require manual handling. The linkage component enables the synchronous rotation of the drive rollers on both sides of the mounting frame, so that the two top mounting plates and two middle mounting plates on the two mounting frames move up and down synchronously, making it more convenient for operators to operate. Secondly, the operator can control the connection between the connecting sleeve and the first screw or the second screw through the moving component, so that the top mounting plate and the middle mounting plate can be separated by a single drive motor, making the overall structure of the tile mounting machine more compact.

[0035] 4. The moving block in the horizontal moving assembly not only applies a horizontal thrust to the mounting frame, but also moves vertically up and down in the sliding groove on the top mounting plate. This ensures that the subsequent movement of the top mounting plate in the vertical direction is not affected. Furthermore, the drive motor is a brake motor, which can lock the drive screw after power failure, making the drive screw less prone to self-rotation due to vibration and other factors, thereby improving the stability of the tile mounting machine operation.

[0036] 5. The fixing components allow the bottom bracket, middle mounting plate, and top mounting plate to form a whole, thus firmly fixing the end of the drive roller, making it less prone to shaking during subsequent drive roller operation and improving the stability of the tile mounting machine.

[0037] 6. The gearbox in the drive mechanism can adjust the speed of the drive gear, so as to meet the required rolling speed when rolling base paper of different thicknesses, improve the quality of the base paper after corrugation, and the operator can quickly connect or disconnect the gear shaft and the output shaft of the gearbox through the coupling.

[0047] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0048] This application discloses a corrugated cardboard production equipment. (Refer to...) Figure 1 and Figure 2 The corrugated cardboard production equipment includes a corrugated board laminating machine body 1, on which a mounting frame 2 is installed. The mounting frame 2 includes a bottom support 21, with two intermediate mounting plates 22 positioned above the bottom support 21. The two intermediate mounting plates 22 are spaced apart on both sides of the bottom support 21 along its length and abut against it. A top mounting plate 23 is also positioned above the intermediate mounting plates 22, abutting against the top of the intermediate mounting plates 22. Driven rollers 3 are respectively installed between the intermediate mounting plates 22 and the bottom support 21 and the top mounting plates 23. Driven rollers 4 are respectively installed on the bottom support 21 and between the two top mounting plates 23, with each drive roller 3 corresponding to one driven roller 4.

A drive mechanism 7 is detachably connected between the tile mounting machine body 1 and one of the drive gears 5, and the drive mechanism 7 is used to drive the drive gear 5 to rotate.

[0050] When workers roll the base paper into corrugated sheets using production equipment, the base paper is first preheated by the paper feeding assembly, with humidity, temperature, and tension adjusted. Then, it enters the preheater for a second adjustment of humidity, temperature, and tension. Finally, under the rolling action of the drive roller 3 and driven roller 4, it is continuously hot-rolled into corrugated paper. When workers need to roll base paper of different thicknesses, they first disconnect the drive mechanism 7 from the drive gear 5. Then, using the quick-release mechanism 6, they move the mounting frame 2 and the drive roller 3 and driven roller 4 mounted on the mounting frame 2 to the outside of the corrugated sheet mounting machine body 1. The operator moves the top mounting plate 23 and the middle mounting plate 22 on the mounting frame 2 upwards and separates them from the bottom bracket 21 by moving the quick-installation mechanism 6. The two drive rollers 3 are then removed from top to bottom and replaced with drive rollers 3 of a thickness that matches the thickness of the original paper. The operator then moves the mounting frame 2 and drive rollers 3 back into the body of the corrugated board machine 1 by moving the quick-installation mechanism 6 again and installs the drive gear 5 onto the end of the drive roller 3. Finally, the drive mechanism 7 is connected to the drive gear 5 to complete the quick replacement of the drive roller 3.

A spline is fixed to the outer side of the drive rod 631, and the connecting sleeve 635 is slidably connected to the drive rod 631 via the spline. A first connecting block 6351 is fixed above the connecting sleeve 635. A first connecting hole is opened at the bottom of the first screw 633. The first connecting block 6351 can be inserted into and attracted into the first connecting hole and cannot rotate relative to the first connecting hole.

A chain 6362 is arranged between the two sprockets 6361. The chain 6362 is located inside the mounting frame 2 and meshes with both sprockets 6361. The sprockets 6361 and the chain 6362 can not only realize the synchronous rotation of the two drive rods 631, but also have high assembly precision, so that when the two drive rods 631 rotate synchronously, it is not easy for slippage and asynchrony to occur, thereby improving the stability of the operation of the mobile quick-assembly mechanism 6.

[0056] Reference Figure 7 The horizontal moving component 62 includes a moving block 621 that slides vertically along one side of one of the top mounting plates 23.

The top mounting plate 23 has a vertical moving groove 232 that matches the T-shaped end of the moving block 621, and the moving block 621 slides within the moving groove 232. The tile mounting machine body 1 has a drive screw 622 along its length. The drive screw 622 is horizontally positioned and rotatably connected to the tile mounting machine body 1, and is threadedly connected to the moving block 621. A drive motor 623 is also provided at one end of the drive screw 622. The drive motor 623 is a brake motor, which can lock the drive screw 622 after power failure, preventing the drive screw 622 from rotating due to vibration or other factors.

Multiple fixing bolts 642 are provided between the connecting ring 641 and the mounting frame 2, and the fixing bolts 642 pass through the connecting ring 641 and are threadedly connected to the mounting frame 2. Multiple positioning blocks 643 are fixedly provided on the side of the connecting ring 641 near the mounting frame 2. The mounting frame 2 has positioning grooves adapted to the positioning blocks 643, and the positioning blocks 643 are inserted into the positioning grooves. The fixing component 64 forms a single unit with the bottom bracket 21, the middle mounting plate 22, and the top mounting plate 23, thereby firmly fixing the end of the drive roller 3, preventing wobbling during subsequent operation of the drive roller 3, and improving the stability of the tile mounting machine.

[0059] When replacing the drive roller 3 using the quick-release mechanism 6, the operator first starts the drive motor 623. Then, the drive motor 623 drives the drive screw 622 to rotate, and the drive screw 622 drives the moving block 621 to move horizontally. The moving block 621 can then drive the mounting frame 2 to move horizontally to the outside of the tile mounting machine body 1. Next, the operator loosens and removes the multiple anti-detachment bolts 654, disconnects the connection between the connecting plate 651 and the end of the drive roller 3, and then moves the connecting plate 651 away from the drive roller 3. The connecting plate 651 can then drive the insertion rod 653 to disengage from the insertion slot 31, thereby disassembling the drive gear 5. Subsequently, the operator loosens the fixing bolt 642 and moves the connecting ring 641 away from the mounting frame 2. The connecting ring 641 can then drive the positioning block 643 to disengage from the positioning slot, releasing the connection and fixation of the bottom bracket 21, the middle mounting plate 22, and the top mounting plate 23.

[0060] The operator then moves the moving rod 6392 upwards, causing the connecting sleeve 635 to move upwards. The connecting sleeve 635 then moves the first connecting block 6351 into the first connecting hole at the bottom of the first screw 633. The operator then starts the drive motor 637, which drives the drive rod 631 to rotate. The drive rod 631 rotates the connecting sleeve 635 and the first connecting block 6351, which are slidably connected to it. The first connecting block 6351 rotates the first screw 633, which in turn moves the top support plate 231 and the top mounting plate 23 downwards, thus opening the bearing holder 61 between the top mounting plate 23 and the middle mounting plate 22. The operator then inserts the drive roller 3 and the bearing at the end of the drive roller 3 into the space between the top mounting plate 23 and the middle mounting plate 22. Replacement: After the drive roller 3 between the top mounting plate 23 and the middle mounting plate 22 is replaced, the worker moves the moving rod 6392 downward. The moving rod 6392 drives the second connecting block 6352 to be inserted into the second connecting hole at the top of the second screw 634 through the connecting sleeve 635. At this time, the first connecting block 6351 is separated from the first connecting hole. Then, the worker starts the transmission motor 637. The transmission motor 637 drives the drive rod 631, the second connecting block 6352 and the second screw 634 to rotate. The second screw 634 drives the middle support plate 221 and the middle mounting plate 22 to move upward, thereby opening the bearing holder 61 between the middle mounting plate 22 and the bottom bracket 21. Then, the worker replaces the drive roller 3 and the bearing at the end of the drive roller 3 located between the middle mounting plate 22 and the bottom bracket 21.

[0061] Reference Figure 8 The drive mechanism 7 includes a gear shaft 71 rotatably connected to one side of the mounting frame 2, and the gear shaft 71 meshes with the drive gear 5. A power motor 72 is installed on one side of the corrugated sheet machine body 1. A gearbox 73 is installed between the power motor 72 and the gear shaft 71. The gearbox 73 is used to adjust the rotational speed of the drive gear 5, thereby facilitating the subsequent rolling of base paper of different thicknesses to meet the required rolling speed and improving the quality of the base paper after corrugation. A coupling 74 is installed between the output shaft of the gearbox 73 and the end of the gear shaft 71. The coupling 74 is used to quickly connect or disconnect the gear shaft 71 and the output shaft of the gearbox 73.

[0062] When the drive mechanism 7 drives the drive gear 5 to rotate, the operator first starts the power motor 72. The power motor 72 converts the power through the gearbox 73 to drive the gear shaft 71 to rotate, and the gear shaft 71 can then drive the drive gear 5 to rotate.

[0063] The implementation principle of a corrugated cardboard production equipment according to this application embodiment is as follows: When the operator rolls the base paper into corrugations using the production equipment, the base paper is first preheated by the paper feeding assembly, and the humidity, temperature, and tension are adjusted. Then, it enters the preheater for a second adjustment of humidity, temperature, and tension. Under the rolling action of the drive roller 3 and the driven roller 4, it can be continuously hot-rolled into corrugated paper. When the operator needs to roll base paper of different thicknesses, the operator first disconnects the gear shaft 71 from the output shaft of the gearbox 73 through the coupling 74. Then, the drive motor 623 is started. The drive motor 623 drives the mounting frame 2, the drive roller 3 on the mounting frame 2, and the driven roller 4 to move to the outside of the corrugated board machine body 1. Then, the drive gear 5 is removed from the end of the drive roller 3 through the connecting assembly 65, and the connection and fixation of the bottom bracket 21, the top mounting plate 23, and the middle mounting plate 22 are released through the fixing assembly 64. Then, the top mounting plate 21 is released through the separation assembly 63. The plate 23 is separated from the intermediate mounting plate 22, and the intermediate mounting plate 22 is separated from the bottom bracket 21 in sequence. Finally, the operator removes the two drive rollers 3 from top to bottom and replaces them with drive rollers 3 of a thickness that matches the thickness of the original paper. This completes the replacement of the drive rollers 3. Then, the operator moves the mounting frame 2 and drive rollers 3 back into the body of the tile laminating machine 1 through the quick-installation mechanism 6 and installs the drive gear 5 to the end of the drive roller 3. Finally, the drive mechanism 7 is connected to the drive gear 5, which completes the quick replacement of the drive rollers 3. When the operator needs to roll the original paper of different thicknesses, the quick-installation mechanism 6 can be used to quickly move the mounting frame 2 and drive rollers 3 to the outside of the body of the tile laminating machine 1 and quickly separate the multiple connecting parts used to fix the drive rollers 3. This allows for the non-destructive removal and replacement of the drive rollers 3, simplifying the disassembly and replacement process. This makes it easier for the operator to roll the original paper of different thicknesses according to the order requirements, improving the practicality and applicability of the tile laminating machine.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
