Description

Technical Field

[0001] This invention relates to the field of tissue paper technology, specifically to a tissue paper hot embossing and rewinding production line. Background Technology

[0002] With the improvement of socio-economic level and people's increasing material needs, the market has higher requirements for the texture and appearance of household paper. At the same time, while pursuing better texture, higher fluffiness, better water absorption and higher tensile strength of the base paper, manufacturers also hope to reduce the cost of equipment and raw materials.

[0003] For example, patent application number CN201120375989.6 includes a paper feeding assembly consisting of multiple sets of paper feeders arranged in a straight line and a slitting and rewinding assembly located at the end of the production line. A sterilization and disinfection assembly and a softening coating assembly are sequentially arranged between the paper feeding assembly and the slitting and rewinding assembly. This roll paper slitting and rewinding production line stacks multiple sets of single-layer paper via the paper feeding assembly and conveys them to the slitting and rewinding assembly for winding and slitting via the sterilization and disinfection assembly and the softening coating assembly. In this production line, the paper rolls are sterilized by the sterilization and disinfection assembly, and softened and scented by the softening coating assembly.

[0004] While the aforementioned patents can effectively improve the production quality of household paper and meet higher-level usage needs, they require separate sterilization and disinfection equipment during production, which increases equipment costs. Furthermore, the paper is prone to lateral movement during unwinding, causing the raw paper to move and resulting in deviations in subsequent production, thus reducing production quality. Summary of the Invention

[0005] The purpose of this invention is to provide a hot embossing and rewinding production line for household paper to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0014] As a preferred embodiment of the present invention, the hot embossing machine is provided with two mutually cooperating embossing components vertically. Each embossing component includes an embossing roller, and both ends of the embossing roller are fixedly connected to connecting discs via connecting shafts. The two connecting discs are provided with fixed discs on the side away from the embossing rollers. The two fixed discs and the connecting discs are connected by an installation component. The side of the two connecting discs away from the fixed discs is respectively fixedly connected to the output end of a fixed motor and a movable shaft. The fixed motor is fixedly installed on the outer wall of the hot embossing machine, and the movable shaft is movably connected to the inner wall of the hot embossing machine.

[0015] As a preferred embodiment of the present invention, the connecting plate and the fixing plate have the same diameter, and both the connecting plate and the fixing plate are provided with the same insertion through hole.

[0016] As a preferred embodiment of the present invention, the mounting assembly includes an L-shaped mounting block welded to the outer wall of the fixed plate. The L-end of the L-shaped mounting block has a cavity, and a limiting plate is movably mounted in the cavity. A plug-in rod is welded to the end face of the limiting plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: In response to the problems raised in the background art, when the present application is carrying out the hot embossing and rewinding production of tissue paper, after the paper roll with the base paper is installed on the mounting roller of the unwinding frame, the baffle in the moving limiting assembly is moved so that the two baffles can move along the placement groove and the mounting roller until the end face abuts against both ends of the paper roll. At this time, the fixing bolts are tightened with tools. The fixing bolts pass through the fixing plate and are threaded into the threaded groove to fix the baffle, preventing the paper roll from moving during unwinding and causing deviations in subsequent production. Before moving the baffle, the welding plate and the connecting block of the sterilization component are connected by connecting bolts. This allows the moving sleeve plate to move on the air jet plate simultaneously through the connecting block and connecting rod when the baffle moves, causing the baffle film to unfold and block the nozzle of the air jet plate. This can accommodate paper rolls of different widths and adjust the ozone spray range of the air jet plate. The unwound paper undergoes preliminary sterilization in the sterilization chamber by the ozone sprayed from the air jet plate, achieving an integrated unwinding and sterilization setup without the need for additional equipment, reducing equipment costs while ensuring production quality. Then, under the action of the guide rollers, the paper enters the wetting chamber of the coating machine for impregnation. After that, it is patterned by the hot embossing machine and finally slit and rewound by the slitting and rewinding machine, thereby increasing the texture and aesthetics of the paper, reducing the amount of paper used for the same roll diameter or packaging size, and reducing production costs.

[0030] Please see Figure 1-7 The present invention provides a technical solution:

[0031] A tissue paper hot-pressing and rewinding production line includes a production line 5, which consists of an unwinding frame 1, a liquid coating machine 2, a hot-pressing machine 3, and a slitting and rewinding machine 4. The unwinding frame 1 has a placement groove 11 with openings on the top and sides. An installation roller 110 is horizontally arranged in the placement groove 11. A paper roll 103 is sleeved on the installation roller 110. Limiting components 12 are provided on both sides of the paper roll 103 on the installation roller 110. The limiting components 12 include baffles 120 sleeved on the installation roller 110. An L-shaped guide bar 121 is welded to one side of the top of the baffle 120. Fixing plates 122 are symmetrically arranged on one side of the top of the unwinding frame 1. One side wall of the two fixing plates 122 The unwinding frame 1 is welded to the L-shaped rod 121. A disinfection chamber 102 is located inside the unwinding frame 1 on one side of the placement groove 11. First through grooves 1021 of different heights are opened on both sides of the disinfection chamber 102. Two guide rollers 13 are provided inside the disinfection chamber 102 to guide the unwound tissue paper. A sterilization component 14 is provided at the top of the disinfection chamber 102. The sterilization component 14 includes an air jet plate 142, which is connected to an ozone generator 140 via a conduit 141. Baffles 147 are fitted on both sides of the air jet plate 142, and movable sleeves 144 are connected to one end of each baffle 147. The two movable sleeves 144 are fitted onto the air jet plate 142. Two movable sleeves 144 are connected to the baffle 120. The bottom plate of the placement groove 11 has a sliding groove 111. A slider 124 is integrally connected to the bottom center of the baffle 120. The slider 124 is slidably connected to the sliding groove 111. A handle 1221 is installed at the center of the upper surface of the fixed plate 122. Fixing bolts 123 that are threaded to the threaded groove 101 are provided on both sides of the upper surface of the fixed plate 122. The outer walls on both sides of the baffle 120 are in contact with and slidably connected to the inner wall of the placement groove 11. A notch is opened at the top of the side of the baffle 120 away from the L-shaped rod 121, and a welding plate 1201 is provided at its top. One end of the welding plate 1201 is located on the notch and below it. A connecting block 146 is provided, which matches the notch. A welding plate 1201 is connected to the connecting block 146 by a connecting bolt 1202. A connecting rod 145 is welded to the outer wall of the connecting block 146 away from the baffle 120. The connecting rod 145 passes through the first through groove 1021, is located in the disinfection chamber 102, and is welded and fixed to the outer wall of the movable sleeve plate 144. An ozone generator 140 is installed on the top of the unwinding frame 1 near the coating machine 2. Mounting plates 143 are welded to both ends of the jet plate 142. Both mounting plates 143 are fixedly connected to the inner wall of the disinfection chamber 102. The ends of the two baffles 147 are respectively bonded and fixed to the movable sleeve plate 144 and the mounting plate 143.

[0032] In the production of thermo-embossed rewinding of tissue paper, after the paper roll 103 with the base paper is installed on the mounting roller 110 of the unwinding frame 1, the baffles 120 in the movable limiting assembly 12 are moved along the placement groove 11 and the mounting roller 110 until their end faces abut against both ends of the paper roll 103. At this time, the fixing bolts 123 are tightened with a tool so that the fixing bolts 123 pass through the fixing plate 122 and are threadedly connected to the threaded groove 101, thus fixing the baffles 120 and preventing the paper roll 103 from moving during unwinding, which would cause deviations in subsequent production. Before moving the baffles 120, the welding plate 1201 is connected to the connecting block 146 of the sterilization assembly 14 with the connecting bolts 1202, so that when the baffles 120 move, the moving sleeve plate 144 can be driven simultaneously through the connecting block 146 and the connecting rod 145. The paper moves on the jet plate 142, causing the baffle 147 to unfold and block the nozzle of the jet plate 142. The ozone generated by the ozone generator 140 is input into the jet plate 142 through the conduit 141 and is ejected from the nozzle on the lower surface. This allows it to adapt to paper rolls 103 of different widths and adjust the ozone spray range of the jet plate 142. The unwound paper is initially disinfected in the disinfection chamber 102 by the ozone sprayed from the jet plate 142, realizing an integrated setting of unwinding and disinfection without the need for additional equipment, reducing equipment costs while ensuring production quality. Then, under the action of the guide roller 13, it enters the coating machine 2 for paper impregnation, and then the hot embossing machine 3 shapes the pattern. Finally, it is slit and rewound by the slitting and rewinding machine 4, thereby increasing the texture and aesthetics of the paper, reducing the amount of paper used for the same roll diameter or packaging size, and reducing production costs.

[0033] For examples, please refer to Figure 1 and Figure 3The coating machine 2 has a water tank 22 at the top, and a wetting chamber 201 is opened below the water tank 22. Second passageways 2011 for tissue paper to pass through are opened on both sides of the wetting chamber 201. A liquid inlet pipe 220, identical to that of the water tank 22, is located on one side of the top of the coating machine 2. A first pump body 221 is installed at the bottom of the water tank 22. The output port of the first pump body 221 is connected to a delivery pipe 222. Two telescopic hoses 223 extending into the wetting chamber 201 are installed on the delivery pipe 222. A coating assembly 23 is located in the wetting chamber 201. The coating assembly 23 includes an upper spray plate 230 and a lower spray plate 231. The two telescopic hoses 223 are respectively connected to the upper spray plate 230 and the lower spray plate 231. Telescopic rods 232 are symmetrically installed on the outer walls of the upper spray plate 230 and the lower spray plate 231 on the side away from the tissue paper. Each telescopic rod 232 is connected to the top plate of the wetting chamber 201. The coating machine 2 is fixedly connected to the base plate. Inside the coating machine 2, a drive chamber 234 is provided on one side of the wetting chamber 201. A bidirectional lead screw 235 is vertically movable in the drive chamber 234. Both ends of the bidirectional lead screw 235 are threaded with movable plates 233. The two movable plates 233 are fixedly connected to the outer walls of the upper spray plate 230 and the lower spray plate 231, respectively. A rotating shaft 236 is fixedly connected to the top of the bidirectional lead screw 235. A drive motor 237 is connected to the top of the rotating shaft 236. The drive motor 237 is fixed to the top of the coating machine 2. A liquid accumulation tank 24 is provided below the wetting chamber 201. A second pump body 240 is installed at the bottom of the liquid accumulation tank 24. A liquid guide pipe 241 is provided on the outer wall of the coating machine 2. Both ends of the liquid guide pipe 241 are connected to the output port of the second pump body 240 and the water tank 22, respectively. A climbing frame 21 is provided on one side of the liquid guide pipe 241 and is fixedly connected to the outer wall of the coating machine 2.

[0034] When the unwound paper enters the coating machine 2, it passes through the second through slots 2011 on both sides. At this time, the drive motor 237 in the coating assembly 23 works to drive the rotating shaft 236 to rotate. The rotating shaft 236 drives the bidirectional lead screw 235 to rotate. The two movable plates 233 respectively drive the upper spray plate 230 and the lower spray plate 231 to move closer to the paper under the restriction of the telescopic rod 232, following the rotation of the bidirectional lead screw 235, until the two ends of the upper spray plate 230 and the lower spray plate 231 abut together. At the same time as the coating assembly 23 moves, the first pump body 221 works to pump the liquid in the water tank 22 through The infusion tube 222 and the telescopic hose 223 are respectively sent into the upper spray plate 230 and the lower spray plate 231 and sprayed onto the paper to wet it. The nozzles of the two spray plates are atomizing nozzles, so that the sprayed liquid is atomized and falls onto the paper. Excess liquid is collected on the bottom plate of the wetting chamber 201 and flows into the liquid collection tank 24 for collection. The second pump body 240 can be operated at any time to send the liquid collected in the liquid collection tank 24 back into the water tank 22 through the liquid guide tube 241 to achieve circulation. The staff can use the climbing frame 21 to put the hose used for infusion into the liquid filling tube 220 to add liquid to the water tank 22.

[0035] For examples, please refer to Figure 1 , Figure 5 , Figure 6 and Figure 7 The hot embossing machine 3 has two vertically arranged embossing components 31 that cooperate with each other. Each embossing component 31 includes an embossing roller 311. Both ends of the embossing roller 311 are fixedly connected to connecting discs 313 via connecting shafts 312. The two connecting discs 313 have fixed discs 314 on their sides away from the embossing roller 311. The two fixed discs 314 and the connecting discs 313 are connected by an installation component 32. The output end of a fixed motor 315 and a movable shaft 316 are respectively fixedly connected to the sides of the two connecting discs 313 away from the fixed discs 314. The fixed motor 315 is fixedly installed on the outer wall of the hot embossing machine 3, and the movable shaft 316 is movably connected to the inner wall of the hot embossing machine 3. The connecting discs 313 and the fixed discs 314 have the same diameter, and both the connecting discs 313 and the fixed discs 314 have the same insertion through holes 317. The mounting assembly 32 includes an L-shaped mounting block 320 welded to the outer wall of the fixed plate 314. A cavity 321 is opened inside the L end of the L-shaped mounting block 320. A limiting plate 322 is movably mounted in the cavity 321. A plug-in rod 324 is welded to the end face of the limiting plate 322. The plug-in rod 324 passes through the L-shaped mounting block 320 and is inserted into the plug-in through hole 317 on the connecting plate 313 and the fixed plate 314. A pressure rod 325 is welded to the other end face of the limiting plate 322, which passes through the L-shaped mounting block 320. A spring 326 is sleeved on the pressure rod 325. The two ends of the spring 326 are fixedly connected to the outer wall of the limiting plate 322 and the inner wall of the cavity 321, respectively. An annular electromagnet 323 is installed on the inner wall of the cavity 321 located on one side of the plug-in rod 324. The outer wall of the limiting plate 322 is magnetically attracted to the electromagnet 323.

[0036] When the wetted paper enters the hot embossing machine 3, the operation of the fixed motor 315 in the two embossing components 31 drives the fixed disk 314 to rotate. The rotating fixed disk 314 drives the connecting disk 313 to rotate through the mounting component 32. The connecting disk 313 drives the embossing roller 311 and the movable shaft 316 to rotate through the connecting shaft 312. The two rotating embossing rollers 311 emboss the paper passing between them. When different patterns need to be embossed, the two sliding sealing doors on the outer wall of the hot embossing machine 3 can be opened to expose the inner chamber. Then, the electromagnet 323 can be de-energized through the external control panel to make its magnetism disappear and stop attracting the limiting plate 322. Under the elasticity of the spring 326, the limiting plate 322 drives the insertion rod 324 to move, causing the insertion rod 324 to disengage. Remove the fixing between the fixed plate 314 and the connecting plate 313 by inserting through the holes. Then, pull the embossing roller 311, connecting shaft 312 and connecting plate 313 outward to remove them. Then, put in the embossing roller 311 with the corresponding pattern, so that the connecting plate 313 moves between the L end of the L-shaped mounting block 320 and the fixed plate 314, and align the through holes 317. Then, energize the electromagnet 323 to generate magnetism. Press the pressure rod 325 to push the limiting plate 322 and pull the spring 326 to move for auxiliary installation until the electromagnet 323 magnetically attracts the limiting plate 322. At this time, insert the insertion rod 324 into the through holes 317 on the connecting plate 313 and the fixed plate 314 to complete the replacement and fixation, thereby realizing the convenient disassembly and assembly of the embossing roller 311 to change different patterns.

[0037] The workflow of this invention is as follows: In the production of hot-embossed rewinding of household paper, after the paper roll 103 with the base paper is installed on the mounting roller 110 of the unwinding frame 1, the baffles 120 in the movable limiting assembly 12 are moved along the placement groove 11 and the mounting roller 110 until their end faces abut against both ends of the paper roll 103. At this point, the fixing bolts 123 are tightened with a tool, so that the fixing bolts 123 pass through the fixing plate 122 and are threadedly connected to the threaded groove 101, thus fixing the baffles 120. This prevents the paper roll 103 from moving during unwinding, which could lead to deviations in subsequent production. Before moving the baffles 120, the welding plate 1201 is connected to the connecting block 146 of the sterilization assembly 14 using connecting bolts 1202. When the baffle 120 moves, the connecting block 146 and connecting rod 145 can simultaneously drive the moving sleeve 144 to move on the jet plate 142, causing the baffle 147 to unfold and block the nozzle of the jet plate 142. The ozone generated by the ozone generator 140 is input into the jet plate 142 through the conduit 141 and is ejected from the nozzle on the lower surface, thus adapting to different widths of paper rolls 103 and adjusting the ozone spray range of the jet plate 142. The unwound paper undergoes preliminary disinfection in the disinfection chamber 102 by the ozone sprayed from the jet plate 142, and then enters the coating machine 2 under the action of the guide roller 13, passing through the second through groove 2011 on both sides and the wetting chamber 201. At this time, the drive motor 237 in the coating assembly 23 works to drive the rotating shaft 2 Rotation 36: The rotating shaft 236 drives the bidirectional lead screw 235 to rotate. The two movable plates 233 respectively drive the upper spray plate 230 and the lower spray plate 231 to move closer to the paper under the restriction of the telescopic rod 232, following the rotation of the bidirectional lead screw 235. This continues until the two ends of the upper spray plate 230 and the lower spray plate 231 abut together. While the coating assembly 23 moves, the first pump body 221 operates, sending the liquid in the water tank 22 into the upper spray plate 230 and the lower spray plate 231 through the infusion pipe 222 and the telescopic hose 223, respectively, and spraying it onto the paper to wet it. The nozzles of both spray plates are atomizing nozzles, so that the sprayed liquid is atomized and falls onto the paper. Excess liquid is collected on the bottom plate of the wetting chamber 201 and flows into the liquid collection tank 24 for collection. The second pump 240 can operate at any time, circulating the liquid collected in the liquid collection tank 24 back into the water tank 22 through the liquid guide pipe 241. When the wetted paper enters the hot embossing machine 3, the operation of the fixed motor 315 in the two embossing components 31 drives the fixed plate 314 to rotate. The rotating fixed plate 314 drives the connecting plate 313 to rotate through the mounting component 32. The connecting plate 313 drives the embossing roller 311 and the movable shaft 316 to rotate through the connecting shaft 312. The two rotating embossing rollers 311 emboss the paper passing between them. When different patterns are required, the two sliding sealing doors on the outer wall of the hot embossing machine 3 can be opened to expose the inner chamber. Then, the electromagnet 323 can be de-energized through the external control panel to make its magnetism disappear.The limiting plate 322 is no longer attracted. Under the elasticity of the spring 326, the limiting plate 322 drives the insertion rod 324 to move, so that the insertion rod 324 disengages from the insertion through hole on the fixed plate 314 and the connecting plate 313, and the fixation between them is canceled. At this time, pulling the embossing roller 311, the connecting shaft 312 and the connecting plate 313 outward can remove them. Then, the embossing roller 311 with the corresponding pattern is put in, so that the connecting plate 313 moves into the L end of the L-shaped mounting block 320 and the fixed plate 314, and the insertion through hole 317 is aligned. Then, the electromagnet 323 is energized to generate magnetism. Pressing the pressure rod 325 pushes the limiting plate 322 to pull the spring 326 to move for auxiliary installation until the electromagnet 323 magnetically attracts the limiting plate 322. At this time, the insertion rod 324 inserts into the insertion through hole 317 on the connecting plate 313 and the fixed plate 314 to complete the replacement and fixation. Finally, the slitting and rewinding machine 4 is used for slitting and rewinding to complete the production. ,
