Description

Technical Field

[0001] This utility model relates to the field of boot-shaped press roller technology, and in particular to a boot cover for a boot-shaped press roller. Background Technology

[0002] The boot press roll is a core component of the paper machine, mainly used to improve the dewatering efficiency and paper quality of wet paper sheets. The boot press roll consists of a boot press roll, a back roll, a hydraulic system, etc. The boot press roll adopts a concave design and has a ridge structure to form a wide pressure zone, which improves efficiency through static pressure dewatering.

[0003] During the use of boot-shaped press rolls, boot covers are fitted on the outside of the roll body. The boot cover is the core component for achieving efficient dewatering, and its performance directly affects paper dryness, energy consumption and equipment life. However, the existing boot covers have certain inconveniences in use.

[0004] First, existing boot covers require traction to be fitted onto the outside of the roller frame during use. However, due to the inherent flexibility of the boot covers, irregular deformation (such as local wrinkles or offsets) is prone to occur during traction, making it difficult for the boot covers to move smoothly along the axis of the roller frame. This not only increases the frequency of alignment adjustments but also significantly increases the difficulty and time required for boot cover replacement. In addition, during the boot cover fixing stage, existing solutions mostly rely on flange docking for fixing. However, flanges are difficult to align and position quickly and accurately during installation, requiring repeated fine adjustments to ensure bolt hole matching. Furthermore, multiple sets of bolts must be operated one by one and the sealing performance must be checked during disassembly and assembly. The overall process is cumbersome, which not only prolongs the installation and commissioning cycle but also increases the workload of operators.

[0005] Therefore, we propose a boot cover for a boot-shaped press roller. Utility Model Content

[0006] In the existing technology, the boot sleeve is prone to irregular deformation (such as local wrinkles or displacement) when it is pulled to the roller frame, making it difficult for the boot sleeve to move smoothly along the roller frame axis. In the fixing part, the existing solutions mostly rely on flange docking for fixing, but the flange is difficult to align and position quickly and accurately during the installation process, and repeated fine adjustments are required to ensure the bolt hole matching. This utility model provides a boot sleeve for boot-shaped press rollers.

[0007] The technical solution adopted by this utility model is: a boot cover for a boot-shaped press roller, comprising a boot cover body, an end assembly, and an end plate. The end assembly includes an end cover, a lead screw, a docking ring, a positioning hole, a fastening wire, and an anti-slip pressure plate. The lead screw and the docking ring are both disposed on the outer surface of the front end of the end cover. The lead screw is located around the docking ring. The positioning hole is disposed on the outer wall of the docking ring. The fastening wire is disposed on the outer wall of the end cover. The anti-slip pressure plate is fixedly installed on the outer surface of one end of the fastening wire. Fixing straps are disposed on the outer surfaces of both ends of the boot cover body. A shaft is disposed on the outer surface of the front end of the end plate. A positioning disc is disposed at the rear end of the end plate. A fixing rod is disposed between the positioning disc and the end plate.

[0008] Furthermore, the positioning disk is provided with a docking hole, a shrinkage groove and a docking slot in the middle, the shrinkage groove is located outside the docking slot and the docking hole is located outside the shrinkage groove, the positioning disk is provided with a positioning pin on the outer wall, the positioning pin is provided with a baffle on the outer wall, and a spring is provided between the baffle and the shrinkage groove.

[0009] Furthermore, the end cover and the docking ring are integrally formed, and the end cover is welded to the lead screw.

[0010] Furthermore, the boot cover body and the fixing strap are integrally formed, and the fixing strap is distributed in a ring structure.

[0011] Furthermore, the end plate is fixedly connected to the positioning plate via the fixing rod.

[0012] Furthermore, the positioning discs are integrally formed with the shrinkage groove and the docking groove, and the shrinkage groove and the docking groove are through-hole structures.

[0013] Furthermore, the positioning pin extends through the middle of the shrinkage groove, the baffle is movably connected to the shrinkage groove via the spring, and the front end of the positioning pin has a circular structure.

[0014] The beneficial effects of this utility model are:

[0015] In this invention, the end cap assembly can be mated with the fixing straps at both ends of the boot cover body. The fixing straps can be inserted into the end cap from the rear, and then the fastening wires on the end cap are aligned with the fixing straps. Rotating the fastening wires causes the anti-slip pressure plates to press and secure the fixing straps. During boot cover assembly, the end caps stabilize the ends of the boot cover body, facilitating traction and assembly. This allows the boot cover to move smoothly along the roller frame axis, improving assembly efficiency. When the positioning disc mates with the end cap, it can connect with the end cap through the mating holes. The lead screw completes the docking, and then the docking groove and the docking ring complete the fitting docking. When the docking groove and the docking ring dock, one end of the positioning pin is squeezed and moves backward. During the backward movement, it will compress the spring through the baffle. After docking is completed, the positioning pin corresponds to the positioning hole on the docking ring. At this time, the spring can push the positioning pin into the positioning hole, thereby limiting the docking ring and preventing misalignment between the positioning plate and the end cover. Then, a nut can be installed on the lead screw for fastening. Compared with flange fixing, it can improve the fixing efficiency and avoid repeated alignment and adjustment.

[0024] The following is in conjunction with the appendix Figures 1-5 The present invention will be further described below.

[0025] In order to solve the problems existing in the background art, this application proposes the following technical solution: a boot cover for a boot-shaped press roller.

[0026] The specific technical solution includes a boot cover body 1, an end assembly 2, and an end plate 3. The end assembly 2 includes an end cover 201, a lead screw 202, a mating ring 203, a positioning hole 204, a fastening wire 205, and an anti-slip pressure plate 206. The lead screw 202 and the mating ring 203 are both located on the outer surface of the front end of the end cover 201. The lead screw 202 is located around the mating ring 203. The positioning hole 204 is located on the outer wall of the mating ring 203. The fastening wire 205 is located on the outer wall of the end cover 201. The anti-slip pressure plate 206 is fixedly installed on the outer surface of one end of the fastening wire 205. Fixing straps 4 are provided on the outer surfaces of both ends of the boot cover body 1. A shaft 5 is provided on the outer surface of the front end of the end plate 3. A positioning disc 6 is provided at the rear end of the end plate 3, and a fixing rod 7 is provided between the positioning disc 6 and the end plate 3. When in use, the end assembly 2 can be connected with the fixing strips 4 at both ends of the boot cover body 1, so that the fixing strips 4 can be inserted into the end cover 201 from the rear. Then, the fastening wire 205 on the end cover 201 is aligned with the fixing strip 4, and then the fastening wire 205 is rotated so that the fastening wire 205 drives the anti-slip pressure plate 206 to press and fix the fixing strip 4. When the boot cover body 1 is installed, the end cover 201 can stabilize the end of the boot cover body 1, which facilitates the traction and installation of the boot cover body 1. The boot cover can move smoothly along the axis of the roller frame, which can improve the installation efficiency.

[0027] Furthermore, the end cover 201 and the docking ring 203 are integrally formed structures. The end cover 201 is welded to the lead screw 202. During use, the docking ring 203 facilitates fixed docking with the positioning plate 6, making it easy to fix and install. The lead screw 202 can pass through the positioning plate 6 for connection and fixation.

[0028] Furthermore, the boot cover body 1 and the fixing strap 4 are integrally formed structures. The fixing strap 4 is distributed in a ring structure. The thickness of the fixing strap 4 is less than the thickness of the boot cover body 1. When the fixing strap 4 is fixed, the boot cover body 1 and the inner ring of the end cover 201 are aligned, which facilitates through-fitting.

[0029] Furthermore, the end plate 3 is fixedly connected to the positioning plate 6 via the fixing rod 7. When in use, the end plate 3 can be connected to the drive equipment via the shaft 5, which facilitates the rotation of the overall boot-shaped press roller.

[0030] Reference Figure 4 and Figure 5 As shown, the positioning disk 6 has a docking hole 8, a shrinkage groove 11, and a docking slot 10 in its middle. The shrinkage groove 11 is located outside the docking slot 10, and the docking hole 8 is located outside the shrinkage groove 11. A positioning pin 9 is provided on the outer wall of the positioning disk 6, and a baffle 12 is provided on the outer wall of the positioning pin 9. A spring 13 is provided between the baffle 12 and the shrinkage groove 11. When the positioning disk 6 docks with the end cover 201, it can dock with the lead screw 202 through the docking hole 8. Then, the docking slot 10 and the docking ring 203 are engaged. During docking, one end of the positioning pin 9 is squeezed and moves backward. During this backward movement, the spring 13 is compressed by the baffle 12. After docking is completed, the positioning pin 9 corresponds to the positioning hole 204 on the docking ring 203. At this time, the spring 13 can spring the positioning pin 9 into the positioning hole 204, thereby limiting the docking ring 203 and preventing misalignment between the positioning plate 6 and the end cover 201. Then, a nut can be installed on the lead screw 202 for tightening. Compared with flange fixing, this method can improve the fixing efficiency and avoid repeated alignment adjustments.

[0031] Furthermore, the positioning disc 6 is integrally formed with the shrinkage groove 11 and the docking groove 10. The shrinkage groove 11 and the docking groove 10 are connected. The shrinkage groove 11 can be easily shrunk by the positioning pin 9 during use. The connection between the shrinkage groove 11 and the docking groove 10 makes it easy for the positioning pin 9 to be inserted into the positioning hole 204 for fixing.

[0032] Furthermore, the positioning pin 9 extends through the middle of the shrinkage groove 11, and the baffle 12 is movably connected to the shrinkage groove 11 via the spring 13. The front end of the positioning pin 9 has a circular structure, and the spring 13 can easily spring back and reset the positioning pin 9 during use, making it convenient for the positioning pin 9 to be positioned.

[0033] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0034] In use, the fixing straps 4 at both ends of the boot cover body 1 can be inserted into the end cover 201 from the rear. Then, the fastening wires 205 on the end cover 201 are aligned with the fixing straps 4. Then, the fastening wires 205 are rotated to drive the anti-slip pressure plate 206 to press and fix the fixing straps 4. When the boot cover body 1 is installed, the end cover 201 can stabilize the end of the boot cover body 1, which facilitates the traction and installation of the boot cover body 1. It can make the boot cover move smoothly along the axis of the roller frame, which can improve the installation efficiency. After traction is completed, the end cover 201 can be docked with the positioning plate 6. When the positioning plate 6 docks with the end cover 201, it can be connected to the wire through the docking hole 8. After rod 202 is docked, docking groove 10 and docking ring 203 are fitted together. When docking groove 10 and docking ring 203 are docked, one end of positioning pin 9 is squeezed and moves backward. During the backward movement, it will compress spring 13 through baffle 12. After docking is completed, positioning pin 9 corresponds to positioning hole 204 on docking ring 203. At this time, spring 13 can spring positioning pin 9 into positioning hole 204, thereby limiting docking ring 203 and preventing misalignment between positioning plate 6 and end cover 201. Then, nut can be installed on screw 202 for fastening. Compared with flange fixing, it can improve fixing efficiency and avoid repeated alignment and adjustment.
