Description

Technical Field

[0001] The utility model relates to the technical field of forming wire papermaking, and particularly discloses a wear-resistant three-layer SSB forming wire papermaking device. Background Technique

[0002] After the papermaking equipment is used for a long time, the forming wire will be damaged. Therefore, it is necessary to regularly replace the forming wire. After the existing papermaking equipment is loosened, the forming wire cannot be directly removed from the papermaking equipment, and it is necessary to additionally use a hoisting device to lift the papermaking equipment for replacement, resulting in very inconvenient disassembly and assembly of the forming wire. Content of the Utility Model

[0003] In view of the above defects or deficiencies in the prior art, the present application aims to provide a wear-resistant three-layer SSB forming wire papermaking device, including a papermaking machine body and a forming wire sleeved on the papermaking machine body. A connecting plate is rotatably connected to the outside of the papermaking machine body. A fixing frame, a first fixing plate and a second fixing plate are fixedly installed at the bottom of the papermaking machine body. A tensioning roller sleeved inside the forming wire is rotatably connected to the inside of the connecting plate. A first support is arranged on the outside of the connecting plate. A first cylinder is rotatably connected to the inside of the fixing frame. A first fixing pin fixedly sleeved inside the first support is movably sleeved inside the bottom end of the first cylinder. A support mechanism is arranged on the outside of the first fixing plate. A jacking mechanism is fixedly installed at the bottom of the second fixing plate. Reinforcing plates are arranged on both sides of the bottom of the second fixing plate.

[0004] Preferably, the support mechanism includes a second support and a third support arranged at the bottom of the first fixing plate and a first fixing seat and a second fixing seat arranged on both sides of the first fixing plate. A second cylinder and a third cylinder are respectively rotatably connected to the inside of the second support and the third support. A support rod is rotatably connected to the inside of both the first fixing seat and the second fixing seat through a second fixing pin. A fourth support is arranged on one side of the support rod. A third fixing pin fixedly sleeved inside the fourth support is movably sleeved inside both the second cylinder and the third cylinder.

[0005] Preferably, a limiting rod movably sleeved inside the support rod is movably sleeved inside the first fixing seat.

[0006] Preferably, the jacking mechanism includes a hydraulic cylinder fixedly installed in the middle of the bottom of the second fixing plate and fixing sleeves arranged at the bottom of the second fixing plate and distributed on both sides of the hydraulic cylinder. A support plate is fixedly sleeved on the outside of the bottom end of the hydraulic cylinder. A guide rod fixedly sleeved inside the support plate is movably sleeved inside the fixing sleeve.

[0007] Beneficial Effects:

[0008] 1. The wear-resistant three-layer SSB forming fabric papermaking equipment can slacken the forming fabric while driving the tension roller to rotate through the first cylinder, so that the forming fabric can be detached from the outside of the tension roller and sleeved on the outside of the support rod. And through the drive of the hydraulic cylinder, the papermaking machine body can be lifted while the limiting rod is removed from the inside of the support rod. At this time, through the drive of the second cylinder or the third cylinder, the support rod can be driven to rotate around the axis of the second fixing pin, so as to remove the forming fabric from the outside of the support rod. With this structure, the papermaking equipment can disassemble and assemble the forming fabric without the need for additional hoisting equipment, which is very convenient to use.

[0009] 2. The wear-resistant three-layer SSB forming fabric papermaking equipment can increase the contact area between the hydraulic cylinder and the ground through the support plate, so that the papermaking machine body will not be skewed after being lifted under the drive of the hydraulic cylinder, which is convenient for disassembling and assembling the forming fabric. And through the limiting rod, the support rod can be limited so that the support rod will not rotate around the axis of the second fixing pin. Furthermore, the papermaking machine body can be stably supported through the support rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Please refer to Figures 1-5 , a wear-resistant three-layer SSB forming wire papermaking equipment, including a paper machine body 1 and a forming wire 2 sleeved on the paper machine body 1. A connecting plate 3 is rotatably connected to the outside of the paper machine body 1. A fixed frame 4, a first fixing plate 5 and a second fixing plate 6 are fixedly installed at the bottom of the paper machine body 1. A tensioning roller 7 sleeved on the inner side of the forming wire 2 is rotatably connected inside the connecting plate 3. A first support 8 is arranged on the outside of the connecting plate 3. A first cylinder 9 is rotatably connected to the inside of the fixed frame 4. A first fixing pin 10 fixedly sleeved inside the first support 8 is movably sleeved inside the bottom end of the first cylinder 9. By driving the first cylinder 9, the tensioning roller 7 can be driven to rotate while the forming wire 2 can be tensioned. And by reversing the driving of the first cylinder 9, the tensioning roller 7 can be driven to move in the reverse direction, so that the limiting of the forming wire 2 by the tensioning roller 7 can be released, facilitating the disassembly and assembly of the forming wire 2. A support mechanism 11 is arranged on the outside of the first fixing plate 5. A jacking mechanism 12 is fixedly installed at the bottom of the second fixing plate 6. Reinforcing plates 13 are arranged on both sides of the bottom of the second fixing plate 6. Through the reinforcing plates 13, the structural strength of the second fixing plate 6 can be enhanced, so that the second fixing plate 6 will not generate bending deformation during the process of jacking up the paper machine body 1 by the hydraulic cylinder 121.

[0020] Among them, the support mechanism 11 includes a second support 111 and a third support 112 provided at the bottom of the first fixing plate 5, and a first fixing seat 113 and a second fixing seat 114 provided on both sides of the first fixing plate 5. A second cylinder 115 and a third cylinder 116 are respectively rotatably connected to the inner sides of the second support 111 and the third support 112. A support rod 118 is rotatably connected to the inside of both the first fixing seat 113 and the second fixing seat 114 through a second fixing pin 117. A fourth support 119 is provided on one side of the support rod 118. A third fixing pin 1110 fixedly sleeved inside the fourth support 119 is movably sleeved inside both the second cylinder 115 and the third cylinder 116. After the limiting rod 14 is taken out from the inside of the support rod 118, the limitation of the limiting rod 14 on the support rod 118 can be released. Furthermore, driven by the second cylinder 115 or the third cylinder 116, the support rod 118 can be driven to rotate around the axis of the second fixing pin 117, so as to facilitate the disassembly and assembly of the forming wire 2.

[0021] Among them, a limiting rod 14 movably sleeved inside the support rod 118 is movably sleeved inside the first fixing seat 113. The support rod 118 can be limited and fixed through the limiting rod 14, and the acting force on the second cylinder 115 can be reduced, so that the support rod 118 can stably limit and support the papermaking machine body 1.

[0022] Among them, the jacking mechanism 12 includes a hydraulic cylinder 121 fixedly installed in the middle of the bottom of the second fixing plate 6 and fixing sleeves 122 provided at the bottom of the second fixing plate 6 and distributed on both sides of the hydraulic cylinder 121. A support plate 123 is fixedly sleeved on the outer side of the bottom end of the hydraulic cylinder 121. A guide rod 124 fixedly sleeved inside the support plate 123 is movably sleeved inside the fixing sleeve 122. The cooperation of the fixing sleeve 122 and the guide rod 124 can limit the support plate 123, so that the support plate 123 will not rotate. Furthermore, driven by the hydraulic cylinder 121, the papermaking machine body 1 can be jacked up through the support plate 123, so as to facilitate the disassembly and assembly operation of the forming wire 2.

[0023] When replacing the forming wire 2, start the first cylinder 9 to drive the tensioning roller 7 to rotate around the connecting plate 3, release the limit on the forming wire 2, remove the forming wire 2 from the outside of the tensioning roller 7, and sleeve it on the outside of the support rod 118. Move the limit rod 14 out of the inside of the support rod 118. Start the second cylinder 115 or the third cylinder 116, and drive the support rod 118 to rotate around the axis of the second fixed pin 117 through the drive of the second cylinder 115 or the third cylinder 116. At this time, the forming wire 2 can be taken off from the outside of the support rod 118. Pass the new forming wire 2 through the support rod 118 and sleeve it on the outside of the tensioning roller 7. Start the second cylinder 115 or the third cylinder 116 to drive in the reverse direction and at the same time drive the support rod 118 to reset. Sleeve the limit rod 14 inside the support rod 118. Start the hydraulic cylinder 121 to drive in the reverse direction and at the same time drive the support plate 123 to reset. Support the paper machine body 1 through the support rod 118. Unfold and sleeve the new forming wire 2 on the outside of the tensioning roller 7 and the paper machine body 1. Start the first cylinder 9 to drive the tensioning roller 7 to rotate in the reverse direction and at the same time tension the forming wire 2 through the tensioning roller 7 to complete the replacement of the forming wire 2.
