Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to a quick-release paper machine roll for multi-roll synergistic drying. Background Technology

[0002] In the papermaking process, the drying process not only directly affects the final quality of the paper, but also plays a decisive role in the efficiency and stability of the entire production process. After the paper is formed, it needs to be dried by an efficient drying system to remove excess moisture in order to reach the specified dryness standard, thereby ensuring the physical properties, strength and dimensional stability of the paper and meeting the requirements of subsequent processing and use.

[0003] The traditional process of disassembling and assembling drying rollers requires operators to remove the bolts or other fixing devices that secure the drying rollers one by one. The bolts are usually located in different positions on the drying rollers, and operators need to remove and install them one by one. This process is not only tedious, but also prone to damage or loss of bolts due to improper operation, which in turn affects the normal installation and operation of the equipment.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a mounting bracket on the side frame to fix a cross-shaped retaining ring. The elastic deformation of a telescopic spring drives the dryer roller to move left and right, enabling quick disassembly and installation. During disassembly, squeezing the dryer roller to the left compresses the telescopic spring, causing the roller to move to the left as a whole, disengaging the right-end extension post and insert two from the cross-shaped retaining ring. Then, insert one on the left end is removed, completing the quick disassembly. During installation, compressing the telescopic spring allows the dryer roller to be placed into the mounting bracket. Releasing the pressure causes the telescopic spring to return to its original position, moving the dryer roller to the right, securely engaging both ends in the cross-shaped retaining ring, completing the quick installation. This rapid disassembly and assembly method avoids the complex and time-consuming problems of traditional methods, reducing equipment downtime and improving production efficiency.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] Example: Please combine Figures 1-5 The multi-roller coordinated drying quick-release paper machine roll of this embodiment includes a side frame 1. Several mounting parts 2 are fixedly connected to the surface of the side frame 1. A cross retaining ring 3 is rotatably connected to the inner wall of the mounting parts 2. An insert 4 is engaged inside the cross retaining ring 3. A contact rod 5 is fixedly connected to the surface of the insert 4. A telescopic spring 6 is fixedly connected to the surface of the contact rod 5. A recovery sleeve 7 is fixedly connected to the surface of the telescopic spring 6. A dryer roll 8 is fixedly connected to the surface of the recovery sleeve 7. An extension column 9 is fixedly connected to the right end of the dryer roll 8. An insert 10 is fixedly connected to the surface of the extension column 9. The cross retaining ring 3 is fixed by the mounting parts 2 on the side frame 1. The insert 4 and insert 10 are engaged inside the cross retaining ring 3. The quick assembly and disassembly of the dryer roll 8 are achieved through the contact rod 5, the telescopic spring 6, and the recovery sleeve 7. Under the action of an external driving device, the dryer roll 8... It is rotatable, and the high-temperature fluid inside dries the paper through the roller wall. During disassembly, the dryer roller 8 is squeezed to the left, causing the recovery sleeve 7 at its left end to squeeze the telescopic spring 6. The telescopic spring 6 is compressed, and the dryer roller 8 moves to the left as a whole. The extension column 9 and the second insert 10 on the right side disengage from the cross retaining ring 3, completing the disassembly of the right end. Then, the first insert 4 on the left end is removed from the cross retaining ring 3 to achieve quick disassembly. During installation, the telescopic spring 6 is compressed first, the dryer roller 8 is placed into the installation part 2, and the first insert 4 is inserted into the left cross retaining ring 3. The telescopic spring 6 is compressed. The dryer roller 8 is adjusted, the pressure is released, the telescopic spring 6 returns to its original position, and the dryer roller 8 is pushed to the right, so that the extension column 9 and the second insert 10 are inserted into the right cross retaining ring 3. The preload of the telescopic spring 6 makes the contact rod 5 and the first insert 4 firmly locked in the left cross retaining ring 3, completing the quick installation.

[0020] There are two cross-shaped retaining rings 3. The two cross-shaped retaining rings 3 are rotatably connected to both sides of the inner wall of the mounting part 2, so that the two ends of the dryer roller 8 can be respectively engaged in the inside of the two cross-shaped retaining rings 3 through the first insert 4 and the second insert 10, thereby realizing the stable fixation and rotation of the dryer roller 8.

[0021] The cross retaining ring 3 has a groove inside, which is compatible with the first insert 4 and the second insert 10, so that the first insert 4 and the second insert 10 can be accurately engaged in the groove of the cross retaining ring 3, thereby realizing the quick disassembly and assembly and stable fixation of the dryer roller 8.

[0022] One end of the dryer roller 8 is engaged with the inside of one of the cross rings 3 by an insert 4, and the other end of the dryer roller 8 is engaged with the inside of another cross ring 3 by an insert 10.

[0023] The dryer roller 8 is a hollow dryer roller. The surface of the dryer roller 8 is provided with an addition groove. The inside of the addition groove is provided with a sealing plug ring 11, which allows personnel to add high-temperature fluid, such as heat transfer oil, into the inside of the dryer roller 8 through the addition groove to dry the paper. The sealing plug ring 11 is used to seal the addition groove to prevent the high-temperature fluid from leaking.

[0024] Both sides of the outer surface of the mounting part 2 are provided with clearance slots 12. The clearance slots 12 are used to connect the external drive device with the cross retainer 3. The personnel use the external drive device to fix the cross retainer 3 through the clearance slots 12. The external drive device drives the cross retainer 3 to rotate along the surface of the mounting part 2, thereby driving the dryer roller 8 to rotate, so as to dry the paper.

[0025] Both sides of the lower surface of the side frame 1 are fixedly connected to the mounting base plate 13. Bolt slots are provided at the four corners of the surface of the mounting base plate 13. There are two side frames 1. The two side frames 1 are fixedly connected to the two sides of the outer surface of the mounting part 2 respectively. The equipment can be installed in a suitable position according to different processing environments and needs, which improves the adaptability and flexibility of the equipment.

[0026] The implementation principle of the quick-release paper machine roller for multi-roller collaborative drying in this application embodiment is as follows: First, place the two side frames 1 in the predetermined installation position, and use the mounting base plates 13 fixed on both sides of the lower surface of the side frame 1, and use the bolt slots at the four corners of the mounting base plate 13 to firmly install the side frame 1 in the appropriate processing position with bolts.

[0027] When the dryer roller 8 needs to be disassembled or maintained, the operator first squeezes the dryer roller 8 to the left, causing the recovery sleeve 7 at the left end to squeeze the telescopic spring 6. As the telescopic spring 6 is compressed, the dryer roller 8 moves to the left as a whole, and the extension column 9 and the second insert 10 at the right end disengage from the right cross retaining ring 3, completing the disassembly of the right end. Then, the first insert 4 at the left end is removed from the left cross retaining ring 3, thus achieving the quick disassembly of the dryer roller 8.

[0028] When the dryer roller 8 needs to be installed, firstly, by pushing the dryer roller 8 to the left, the telescopic spring 6 is compressed, reducing the overall length of the dryer roller 8. Then, the left end insert 4 of the dryer roller 8 is aligned with the cross retaining ring 3 on the left side of the inner wall of the mounting part 2 and inserted into the slot. At this time, the telescopic spring 6 is compressed, and the left end of the dryer roller 8 is fixed in the left cross retaining ring 3. Next, the position of the dryer roller 8 is adjusted to ensure that it is correctly placed in the mounting part 2. The pressure on the telescopic spring 6 is slowly released, the telescopic spring 6 returns to its original position, and the dryer roller 8 is pushed to the right. As the dryer roller 8 moves to the right, the extension post 9 and the insert 10 at its right end are simultaneously inserted into the right cross retaining ring 3. When the extension post 9 and the insert 10 are fully inserted into the right cross retaining ring 3, the preload of the telescopic spring 6 makes the contact rod 5 and the insert 4 firmly locked in the left cross retaining ring 3, thus completing the quick installation of the dryer roller 8.

[0029] High-temperature fluid, such as heat transfer oil, is added to the inside of the dryer roller 8 through the adding groove on its surface. The external drive device is then connected to the cross retainer 3. The design of the clearance slot 12 provides sufficient space and connection convenience for the external drive device, ensuring that the drive device can be accurately fixed to the cross retainer 3. After the external drive device is started, it drives the cross retainer 3 to rotate along the surface of the mounting part 2, thereby driving the dryer roller 8 to rotate. During the rotation of the dryer roller 8, the high-temperature fluid inside it dries the paper evenly through the roller wall, ensuring the drying quality of the paper.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
