Technical Field
[0001] This application relates to the field of papermaking machine technology, and in particular to a papermaking machine with easily removable and replaceable rolls. Background Technology
[0002] As the core equipment in the papermaking industry, the performance and operating efficiency of the papermaking machine directly affect the production quality and output of paper. As a key component in the papermaking machine used to wind paper, the winding roll plays a vital role in the papermaking process. With the continuous changes in production needs, the disassembly and replacement of the winding roll has become an important part of the daily maintenance and operation of the papermaking machine.
[0003] Existing paper machine roll installation structures are typically fixed and complex, and the connection between the roll and the main body of the paper machine often lacks flexibility and convenience. When disassembling and replacing the roll, a lot of time and manpower are often required. Operators usually need to use a variety of tools to disassemble and install multiple complex connecting parts. This process is not only cumbersome, but also prone to damage to equipment parts due to improper operation, increasing maintenance costs. To solve the above problems, this application provides a paper machine with rolls that are easy to disassemble and replace.
[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content
[0005] To address the aforementioned problems, this application provides a papermaking machine with easily removable and replaceable rolls.
[0006] The papermaking machine with easily disassembled and replaceable rolls provided in this application adopts the following technical solution:
[0007] A papermaking machine with an easily removable and replaceable roll includes two supports for supporting the machine body, which is fixed between the two supports. The machine body has an arc-shaped opening, and an arc-shaped clamping block two is fixed to the inner wall of the opening. An arc-shaped clamping block one is located within the opening, and the two clamping blocks are interlocked. A roll is rotatably mounted between the two clamping blocks. A sliding assembly is located within the opening to drive the clamping block one away from or towards the clamping block two. The top of each support has a motor one for driving the roll to rotate and a moving assembly for driving the motor one away from the roll. A limiting assembly is located on one side of the motor one, which simultaneously limits the roll when the motor one drives it to rotate.
[0008] Preferably, a button is fixed on one side of the first arc-shaped clamping block, and an insertion port is opened on one side of the second arc-shaped clamping block. The button is inserted into the insertion port. Multiple balls are equidistantly rotated on the inner sides of both the first and second arc-shaped clamping blocks, and the multiple balls rotate at both ends of the roller surface.
[0009] Preferably, the sliding assembly includes a cylinder, a connecting frame, and a connecting rod. The cylinder is fixed to the bottom of the paper machine body, the telescopic end of the cylinder is fixed to the connecting frame, one end of the connecting frame is fixed to the connecting rod, and the end of the connecting rod away from the connecting frame is fixed to one side of the arc-shaped clamping block.
[0010] Preferably, the movable component includes a mounting frame, a guide rod, a lead screw, and a second motor. The first motor is fixed inside the mounting frame. A sliding groove is provided on the top of the support. The guide rod is fixed inside the sliding groove. The lead screw rotates inside the sliding groove. The second motor is fixed to one side of the support. The rotor end of the second motor is fixed to the lead screw. The mounting frame slides inside the sliding groove. The mounting frame is threadedly connected to the lead screw. The mounting frame can slide on the surface of the guide rod.
[0011] Preferably, both ends of the roller are fixed with insert blocks, and the insert blocks are inserted into the rotor end of the motor.
[0012] Preferably, the limiting component includes a connecting block, a limiting rod one, and a limiting rod two. The connecting block is fixed to one side of the mounting frame, and both the limiting rod one and the limiting rod two are fixed to one side of the connecting block. A limiting groove two is formed on the surface of the connecting rod. When the motor one drives the roll to rotate, a limiting groove one is formed on one side of the paper machine body. The limiting rod one is inserted into the limiting groove one, and the limiting rod two is inserted into the limiting groove two.
[0013] In summary, this application includes the following beneficial technical effects:
[0014] By opening an arc-shaped opening on the paper machine body and installing an arc-shaped clamping block two and a movable arc-shaped clamping block one on the inner wall of the arc-shaped opening, the roller can be quickly clamped and released by using a sliding component to drive the arc-shaped clamping block one away from or towards the arc-shaped clamping block two. When the roller needs to be disassembled, simply operate the sliding component to move the arc-shaped clamping block one away from the arc-shaped clamping block two, and the roller can be easily removed from between the two. When installing a new roller, operate the sliding component in the opposite direction to move the arc-shaped clamping block one towards the arc-shaped clamping block two to clamp the roller. Compared with related technologies, the whole process does not require the use of multiple complex tools, nor does it require the tedious disassembly and installation of multiple connecting parts. This effectively shortens the time for roller disassembly and replacement, improves operating efficiency, reduces production delays caused by equipment downtime for roller replacement, and effectively improves the overall production efficiency of the paper machine.

[0021] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0022] This application discloses a papermaking machine with easily removable and replaceable rolls. (See also...) Figure 1-5 A paper machine with an easily detachable and replaceable roller includes two supports 7 for supporting the paper machine body 1. The paper machine body 1 is fixed between the two supports 7. An arc-shaped opening 2 is provided on the paper machine body 1. An arc-shaped clamping block 2 18 is fixed to the inner wall of the arc-shaped opening 2. An arc-shaped clamping block 15 is provided inside the arc-shaped opening 2. The arc-shaped clamping block 15 and the arc-shaped clamping block 2 18 are inserted and engaged. A roller 3 is rotatably arranged between the arc-shaped clamping block 15 and the arc-shaped clamping block 2 18. A sliding component is provided inside the arc-shaped opening 2 to drive the arc-shaped clamping block 15 away from or closer to the arc-shaped clamping block 2 18. A motor 5 for driving the roller 3 to rotate and a moving component for driving the motor 5 away from the roller 3 are provided on the top of the support 7. A limiting component is provided on one side of the motor 5. When the motor 5 drives the roller 3 to rotate, the limiting component simultaneously limits the roller 3.
[0023] During installation, the first arc-shaped clamp 15 and the second arc-shaped clamp 18 are separated, leaving sufficient space between them for placing the roll 3. The roll 3 is placed between the first arc-shaped clamp 15 and the second arc-shaped clamp 18. The sliding assembly is activated, and the sliding assembly drives the first arc-shaped clamp 15 to move toward the second arc-shaped clamp 18. As the first arc-shaped clamp 15 approaches, the roll 3 is fixed on the paper machine body 1, and the roll 3 can rotate between the first arc-shaped clamp 15 and the second arc-shaped clamp 18. After the roll 3 is installed, the first motor 5 is positioned close to the roll 3, and its output shaft is connected to the coupling of the roll 3. The first motor 5 is activated, and its output shaft begins to rotate. The coupling drives the roll 3 to rotate together, thereby realizing the paper winding operation. At the same time, the limiting assembly limits the roll 3 to prevent unstable situations such as axial movement and radial sway during the rotation of the roll 3, ensuring that the roll 3 can rotate smoothly and ensuring the quality and stability of paper winding.
[0024] When it is necessary to disassemble the roll 3, the moving component is activated to drive the motor 5 away from the roll 3, so that the output shaft of the motor 5 is disconnected from the drive end of the roll 3, making room for the disassembly of the roll 3. The sliding component is then activated to drive the arc-shaped clamp 15 away from the arc-shaped clamp 2 18. As the arc-shaped clamp 15 moves, it moves away from the arc-shaped clamp 2 18 until the roll 3 can be removed, thus completing the disassembly of the roll 3. This achieves convenient disassembly and replacement of the roll 3, as well as stable drive and limit during operation, improving the maintenance efficiency and operational reliability of the paper machine.
[0025] Reference Figure 1-5 A button 16 is fixed on one side of the arc-shaped clamping block 15, and a slot 19 is opened on one side of the arc-shaped clamping block 2. The button 16 and the slot 19 are inserted and engaged. The insertion and engagement of the button 16 and the slot 19 increases the connection strength between the arc-shaped clamping block 15 and the arc-shaped clamping block 2, allowing them to clamp the roller 3 more tightly. This prevents the roller 3 from loosening or separating due to factors such as the tension of the paper during rotation, ensuring the stability of the roller 3 installation. At the same time, the engagement of the button 16 and the slot 19 can play a positioning role. When installing the roller 3, it can ensure that the arc-shaped clamping block 15 and the arc-shaped clamping block 2 are accurately aligned, so that the roller 3 is in the correct installation position, reducing the problem of unstable rotation of the roller 3 caused by installation deviation.
[0026] Both the first arc-shaped clamp 15 and the second arc-shaped clamp 18 have multiple balls 17 rotating at equal intervals on their inner sides. The balls 17 rotate at both ends of the surface of the roller 3. When the first motor 5 drives the roller 3 to rotate, relative motion occurs between the surface of the roller 3 and the balls 17. The balls 17 roll on the surface of the roller 3. The uniform distribution and rolling action of the balls 17 can make the roller 3 more evenly stressed during rotation, reduce vibration and shaking caused by uneven friction, improve the stability of the roller 3 rotation, and thus ensure the quality of paper winding.
[0027] Reference Figure 1-3 The sliding assembly includes a cylinder 12, a connecting frame 13, and a connecting rod 14. The cylinder 12 is fixed to the bottom of the paper machine body 1. The telescopic end of the cylinder 12 is fixed to the connecting frame 13. One end of the connecting frame 13 is fixed to the connecting rod 14. The end of the connecting rod 14 away from the connecting frame 13 is fixed to one side of the arc-shaped clamping block 15. When installing the roll 3, the cylinder 12 is activated to extend, pushing the connecting frame 13 and its connecting rod 14 and the arc-shaped clamping block 15 away from the roll 3 and the arc-shaped clamping block 18, thereby realizing the precise movement of the arc-shaped clamping block 15 within the arc-shaped opening 2, which facilitates the installation and disassembly of the roll 3.
[0028] Reference Figure 1 The moving assembly includes a mounting frame 6, a guide rod 9, a lead screw 10, and a second motor 11. The first motor 5 is fixed inside the mounting frame 6. A groove 8 is provided on the top of the support 7. The guide rod 9 is fixed inside the groove 8. The lead screw 10 rotates inside the groove 8. The second motor 11 is fixed to one side of the support 7. The rotor end of the second motor 11 is fixed to the lead screw 10. The mounting frame 6 slides inside the groove 8. The mounting frame 6 is threadedly connected to the lead screw 10. The mounting frame 6 can slide on the surface of the guide rod 9. When the second motor 11 is started, the lead screw 10 rotates. Under the guidance of the guide rod 9, the mounting frame 6 and the first motor 5 on it move away from or closer to the roller 3.
[0029] Reference Figure 4 Both ends of the roller 3 are fixed with insert blocks 4. The insert blocks 4 are inserted into the rotor end of the motor 5. As the mounting frame 6 moves, the rotor end of the motor 5 gradually approaches the insert block 4 at one end of the roller 3 until the insert block 4 is inserted into the rotor end of the motor 5, establishing the drive connection between the motor 5 and the roller 3. This improves the installation and disassembly efficiency of the roller 3, reduces equipment downtime for maintenance, and helps improve the production efficiency of the paper machine.
[0030] Reference Figure 2The limiting assembly includes a connecting block 20, a limiting rod 1 21, and a limiting rod 23. The connecting block 20 is fixed to one side of the mounting frame 6. The limiting rod 1 21 and the limiting rod 23 are both fixed to one side of the connecting block 20. A limiting groove 24 is opened on the surface of the connecting rod 14. When the motor 1 5 drives the roller 3 to rotate, a limiting groove 1 22 is opened on one side of the paper machine body 1. The limiting rod 1 21 and the limiting groove 1 22 are inserted and engaged, which can effectively prevent unnecessary movement of the mounting frame 6 in the horizontal direction and ensure the stability of the drive connection between the motor 1 5 and the roller 3. The limiting rod 23 and the limiting groove 24 are inserted and engaged, which restricts the movement of the connecting rod 14 in the direction perpendicular to its length, preventing the connecting rod 14 from shaking or deviating during the rotation of the roller 3, ensuring that the arc-shaped clamping block 15 can stably clamp the roller 3 and maintain the smoothness of the rotation of the roller 3.
