Description

Technical Field

[0001] This invention relates to the field of unwinding devices, specifically to an unwinding device for papermaking with a tension adjustment structure. Background Technology

[0002] The core purpose of a paper unwinding device is to smoothly and efficiently unwind stored paper rolls into continuous sheets of paper, and to ensure that the paper maintains stable quality during the unwinding process, so as to provide a suitable substrate for subsequent processing steps such as rewinding, slitting, coating, and printing. Currently, when unwinding paper rolls in winter, the extremely low ambient temperature causes the moisture inside the paper to condense rapidly, and the fiber structure to become tight and stiff. The paper is prone to a significant reduction in flexibility due to the low temperature, becoming exceptionally fragile. Adjusting the tension during the unwinding process can lead to paper breakage, and may even affect the normal operation of the unwinding process, reducing production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a paper unwinding device with a tension adjustment structure. A portion of the steam is transmitted through both ends of each set of transmission pipes to the interior of each set of fifth pipes. Each set of fifth pipes transmits the steam together to the interior of the tension rod, and sprays it onto the paper surface through the exhaust hole to soften the paper surface. This prevents the paper from becoming abnormally brittle due to the low winter temperature when the unwinding machine is performing paper roll unwinding operations. This would prevent the paper from breaking when adjusting the tension during the unwinding process, thus affecting the normal operation of the unwinding work and reducing production efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a papermaking unwinding device with a tension adjustment structure, comprising an unwinder, an auxiliary component installed on the unwinder, the auxiliary component comprising two sets of transmission pipes connected by connecting pipes, each set of transmission pipes having a first fixed rod connected to one side, each first fixed rod having a first telescopic rod slidably connected inside, one end of each first telescopic rod being fixedly connected to a fixed frame, both ends of each set of transmission pipes having a second fixed rod connected to both ends, each second fixed rod having a second telescopic rod slidably connected inside, one end of each second telescopic rod being fixedly connected to a clamping plate, the unwinder having a tensioning component installed on the unwinder, the tensioning component comprising two sets of cylinders, the output ends of each set of cylinders being fixedly connected to a tensioning rod, one side of each tensioning rod having multiple sets of exhaust holes, both ends of each tensioning rod being connected to both ends of the transmission pipes.

[0005] Preferably, one of the sets of transmission pipes is provided with an air inlet on one side, and a steam engine is connected to the air inlet. Each set of first fixing rods is fixed to the unwinding machine by a fixing bracket.

[0006] Preferably, each group of first fixed rods has a first pipe connected to one side, each group of first pipes is equipped with a first pressure valve, and one end of each group of first pipes is connected to one side of the transmission pipe.

[0007] Preferably, each group of first fixing rods has a second pipe connected to the other side, one end of each group of second pipes penetrates through the fixing frame, and each group of second pipes is equipped with a first solenoid valve.

[0008] Preferably, each set of first fixed rods is provided with a first spring inside, one end of each set of first springs is fixedly connected to the inside of the first fixed rod, and the other end of each set of first springs is fixedly connected to the other end of the first telescopic rod.

[0009] Preferably, each group of second fixing rods is connected to a third pipe on one side, each group of third pipes is equipped with a second pressure valve, and one end of each group of third pipes is connected to both ends of the transmission pipe.

[0010] Preferably, one side of each group of second fixing rods is fixedly connected to the unwinding machine, and the other side of each group of second fixing rods is connected to a fourth pipe, and each group of fourth pipes is equipped with a second solenoid valve.

[0011] Preferably, each set of second fixed rods is provided with a second spring inside, one end of each set of second springs is fixedly connected to the inside of the second fixed rod, and the other end of each set of second springs is fixedly connected to the other end of the second telescopic rod.

[0012] Preferably, the unwinding machine has grooves on both sides, and the two ends of the tensioning rod pass through the two sets of grooves respectively. Both ends of the tensioning rod are slidably connected to the grooves. The two ends of the tensioning rod are connected to a fifth pipe, and one end of each set of the fifth pipes is connected to one end of each set of transmission pipes.

[0013] Compared with the prior art, the beneficial effects of the present invention are: In this invention, a portion of the steam is transmitted through both ends of each set of transmission pipes to the interior of each set of fifth pipes. Each set of fifth pipes then transmits the steam together to the tension rod, which is then sprayed onto the paper surface through the exhaust holes. This softens the paper surface and prevents it from becoming abnormally brittle due to the low winter temperature during unwinding operations. This prevents the paper from breaking when adjusting the tension during unwinding, which would otherwise affect the normal operation of the unwinding process and reduce production efficiency.

[0014] In this invention, a portion of steam is transmitted through each set of transmission pipes to the interior of each pair of first fixed rods. The steam drives each set of first springs and each set of first telescopic rods to extend. Each set of first telescopic rods drives the fixed frame to extend, and each set of fixed frames extends to the fixed nut of each set of clamps, fixing the fixed nut on the clamps. This prevents the clamp fixed nut from loosening due to mechanical vibrations during unwinding, which would affect the stability and quality of the paper roll unwinding.

[0015] This invention transmits steam through each group of third pipes to the interior of each group of second fixed rods. The steam drives each group of second springs and each group of second telescopic rods to extend. Each group of second fixed rods drives each group of clamping plates to clamp the paper roll and paper drum on both sides of each group of driving rollers. This prevents the paper roll from shifting axially or radially on the driving rollers during the unwinding process due to factors such as vibrations generated by the equipment operation, changes in paper tension during unwinding, and possible external interference. This prevents the unwinding accuracy from being affected, causing problems such as uneven unwinding, wrinkles, or tears, thus reducing product quality and production efficiency.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] See Figures 1 to 6 As shown, the present invention provides a papermaking unwinding device with a tension adjustment structure, including an unwinder 1, an auxiliary component 2 installed on the unwinder 1, the auxiliary component 2 including two sets of transmission pipes 201 connected by a connecting pipe 214, a first fixed rod 203 connected to one side of each of the two sets of transmission pipes 201, a first telescopic rod 204 slidably connected inside each of the first fixed rods 203, a fixed frame 205 fixedly connected to one end of each of the first telescopic rods 204, a second fixed rod 209 connected to both ends of each of the two sets of transmission pipes 201, a second telescopic rod 210 slidably connected inside each of the second fixed rods 209, and a clamping plate 211 fixedly connected to one end of each of the second telescopic rods 210; The staff placed the paper rolls and empty paper drums onto the two sets of drive rollers of the unwinding machine 1. The staff then installed the two sets of drive rollers onto the clamps on both sides of the unwinding machine 1. Each set of clamps was locked in place by the fixing nuts on each set of clamps. Then the staff started the motor. The motor was driven by the gear set and drove the drive rollers with the paper rolls to rotate, starting the unwinding process. The paper was collected again on the drive rollers with the paper drums on the multiple sets of transfer rollers and auxiliary transfer wheels. In winter, when the paper roll is unwound on the unwinding machine 1, the operator starts the steam engine connected to the air inlet of one set of transmission pipes 201. The steam engine transmits steam into the interior of that set of transmission pipes 201. One set of transmission pipes 201 then transmits steam to the interior of the other set of transmission pipes 201 via connecting pipe 214. Both sets of transmission pipes 201 transmit steam together. Since the first telescopic rod 204 of each set is in a retracted state inside the first fixed rod 203 when each set is not in operation, the first pressure valve on each set of first pipes 202 is open at this time. The state is set, and the first solenoid valve on each group of second pipes 207 is closed. Therefore, each group of transmission pipes 201 transmits a portion of steam to the interior of each pair of first fixed rods 203. The steam drives each group of first springs 206 and each group of first telescopic rods 204 to extend. Each group of first telescopic rods 204 drives the fixed frame 205 to extend. Each group of fixed frames 205 extends to the fixed nut of each clamp, fixing the fixed nut on the clamp to prevent the clamp fixed nut from loosening due to mechanical vibrations caused by 1 during unwinding, which would affect the stability and quality of paper roll unwinding. Additionally, when each set of fixed frames 205 is fully in contact with the fixing nuts of the clamps, the first telescopic rod 204 no longer drives the fixed frames 205 to extend, and the air pressure inside each set of first fixed rods 203 no longer rises. At this time, when the first pressure valve on each set of first pipes 202 detects that the pressure inside each set of first fixed rods 203 is approaching equilibrium, the first pressure valve closes the passage of each set of first pipes 202 to maintain the stability of the air pressure inside each set of first fixed rods 203. If liquid appears in the steam inside each set of first fixed rods 203, and the air pressure inside each set of first fixed rods 203 decreases, the first pressure valve on each set of first pipes 202 automatically opens, and the steam is transmitted to the inside of the first fixed rods 203 through the first pipes 202 to replenish the internal air pressure of the first fixed rods 203 in time, thereby ensuring the stable clamping of each set of first telescopic rods 204 with the fixing nuts of each set of clamps through each set of fixed frames 205. Additionally, after unwinding machine 1 finishes unwinding, the steam engine is turned off. The steam engine no longer transmits steam to the inside of each first fixed rod 203 through each set of transmission pipes 201. The operator opens the first solenoid valve on each set of second pipes 207, and the steam inside each set of first fixed rods 203 is discharged through each set of second pipes 207. At this time, the first spring 206 inside each set of first fixed rods 203 is no longer under the pressure of steam. Each set of first springs 206 drives each set of first telescopic rods 204 to rebound, causing each set of first telescopic rods 204 to drive each set of fixed frames 205 away from the fixing nuts of each set of clamps. The operator can loosen the fixing nuts to open each set of clamps, reinstall the two sets of drive rollers on the paper roll and paper drum, and start the unwinding operation again. While some steam is being transferred into the first fixed rod 203 of each group, since the first fixed rod 203 is not in operation, the second telescopic rod 210 of each group is in a retracted state inside the second fixed rod 209 of each group. At this time, the second pressure valve on the third pipe 208 of each group is open, and the second solenoid valve on the fourth pipe 213 of each group is closed. Therefore, another part of the steam is transferred through both ends of the transmission pipe 201 to the third pipe 208 of each group, and the third pipe 208 of each group transfers the steam to the second fixed rod 209 of each group. Inside, steam drives each set of second springs 212 and each set of second telescopic rods 210 to extend. Each set of second fixed rods 209 drives each set of clamping plates 211 to clamp the paper roll and paper drum on both sides of each set of driving rollers. This prevents the paper roll from shifting axially or radially on the driving rollers during the unwinding process due to factors such as vibration generated by the equipment operation, changes in paper tension during unwinding, and possible external interference. This would affect the unwinding accuracy, cause problems such as uneven unwinding, wrinkles or tears, and reduce product quality and production efficiency. Additionally, when each set of clamping plates 211 is in complete contact with the paper roll and paper drum sides of each set of driven rollers, the second telescopic rod 210 no longer drives the clamping plates 211 to extend, and the internal air pressure of each set of second fixed rods 209 no longer rises. At this time, when the second pressure valve on each set of third pipes 208 detects that the internal pressure of each set of second fixed rods 209 tends to be balanced, the second pressure valve on each set of third pipes 208 closes the passage of each set of third pipes 208 to maintain the stability of the internal air pressure of each set of second fixed rods 209. If liquid appears in the steam inside each set of second fixed rods 209, and the internal air pressure of each set of second fixed rods 209 decreases, the second pressure valve on each set of third pipes 208 automatically opens, and the steam is transmitted to the inside of the second fixed rods 209 through the third pipes 208 to replenish the internal air pressure of the second fixed rods 209 in time, thereby ensuring the stable clamping of the paper roll and paper drum sides of each set of driven rollers by each set of clamping plates 211. Additionally, after unwinding machine 1 finishes unwinding, the steam engine is turned off. The steam engine no longer transmits steam to the inside of each group of second fixed rods 209 through each group of transmission pipes 201. The operator opens the second solenoid valve on each group of fourth pipes 213, and the steam inside each group of second fixed rods 209 is discharged through each group of fourth pipes 213. At this time, the fourth pipes 213 inside each group of fourth pipes 213 are no longer under steam pressure. Each group of second springs 212 drives each group of second telescopic rods 210 to rebound, causing each group of second telescopic rods 210 to move each group of clamping plates 211 away from the paper roll and paper drum sides of each group of drive rollers. The operator reinstalls the paper roll and paper drum on the two groups of drive rollers and performs the unwinding operation again. See Figure 7 As shown, a tensioning assembly 3 is installed on the unwinding machine 1. The tensioning assembly 3 includes two sets of cylinders 301. The output ends of the two sets of cylinders 301 are fixedly connected to tensioning rods 303. Multiple sets of exhaust holes 304 are provided on one side of the tensioning rods 303. Both ends of the tensioning rods 303 are connected to both ends of the transmission pipe 201. When the operator starts the two sets of cylinders 301, the two sets of cylinders 301 drive the tension rod 303 to move on the groove of the unwinder 1. When adjusting the tension of the paper, while another part of the steam is transmitted through both ends of each set of transmission pipes 201 to the inside of each set of second fixed rods 209, another part of the steam is transmitted through both ends of each set of transmission pipes 201 to the inside of each set of fifth pipes 305. Each set of fifth pipes 305 transmits steam to the inside of the tension rod 303 and sprays it onto the paper surface through the exhaust hole 304. This softens the paper surface and prevents the paper from becoming abnormally fragile due to the low winter temperature when the unwinder 1 is performing paper roll unwinding operations. This would prevent the paper from breaking when adjusting the tension during the unwinding process, which would affect the normal operation of the unwinding work and reduce production efficiency.

[0020] In an optional embodiment, one of the sets of transmission pipes 201 is provided with an air inlet on one side, and a steam engine is connected to the air inlet. Each set of first fixing rods 203 is fixed to the unwinding machine 1 by a fixing bracket.

[0021] It should be noted that during winter, when the paper roll is unwound on the unwinding machine 1, the operator starts the steam engine connected to the air inlet of one set of transmission pipes 201. The steam engine transmits steam into the interior of one set of transmission pipes 201. One set of transmission pipes 201 transmits steam to the interior of another set of transmission pipes 201 through the connecting pipe 214. The two sets of transmission pipes 201 transmit steam together.

[0022] In an optional embodiment, each set of first fixing rods 203 is connected to a first pipe 202 on one side, each set of first pipes 202 is provided with a first pressure valve, and one end of each set of first pipes 202 is connected to one side of transmission pipe 201.

[0023] It should be noted that after steam is transmitted to the first fixed rod 203, causing the first telescopic rod 204 to extend and the fixed frame 205 to contact the clamp fixing nut, when the internal air pressure of the first fixed rod 203 no longer rises and tends to balance, the first pressure valve closes the passage of the first pipe 202 to maintain stable internal air pressure and ensure stable clamping of the fixing frame 205 on the fixing nut. If the steam inside the first fixed rod 203 liquefies and the air pressure decreases, the first pressure valve automatically opens, allowing steam to be replenished into the first fixed rod 203 through the first pipe 202 to restore the internal air pressure in time and continuously ensure stable clamping of the first telescopic rod 204 on the fixing nut by the fixing frame 205. After unwinding is completed and the steam generator is turned off, the first pressure valve stops working with the system and opens the first solenoid valve to release steam, causing the first spring 206 to drive the first telescopic rod 204 to rebound, allowing the fixing frame 205 to move away from the fixing nut so that the paper roll and paper drum can be reinstalled.

[0024] In an optional embodiment, each set of first fixing rods 203 is connected to a second pipe 207 on the other side, one end of each set of second pipes 207 is connected to the fixing frame, and each set of second pipes 207 is provided with a first solenoid valve.

[0025] It should be noted that when the unwinding machine is working in winter, closing the first solenoid valve allows steam to enter the first fixed rod 203 through the transmission pipe 201 and the first pipe 202, which drives the telescopic rod and other fixed clamp nuts. After unwinding is completed, opening the first solenoid valve allows the steam in the first fixed rod 203 to be discharged, causing the telescopic rod to spring back, making it easier to loosen the nuts and replace the paper roll and paper drum.

[0026] In an optional embodiment, each set of first fixing rods 203 is provided with a first spring 206 inside, one end of each set of first springs 206 is fixedly connected to the inside of the first fixing rod 203, and the other end of each set of first springs 206 is fixedly connected to the other end of the first telescopic rod 204.

[0027] It should be noted that when steam enters the first fixed rod 203, the steam pressure drives the first telescopic rod 204 to extend, so that the fixed frame 205 fixes the clamp and fixes the nut. During unwinding, the rod automatically extends and retracts according to the air pressure change inside the first fixed rod 203 to maintain the internal air pressure stability and ensure stable clamping of the nut. After unwinding is completed, the steam is released and drives the first telescopic rod 204 to spring back, so that the fixed frame 205 moves away from the nut, making it easy to reinstall the paper roll and paper drum.

[0028] In an optional embodiment, each set of second fixing rods 209 is connected to a third pipe 208 on one side, each set of third pipes 208 is provided with a second pressure valve, and one end of each set of third pipes 208 is connected to both ends of the transmission pipe 201.

[0029] It should be noted that during the operation of the unwinder 1, the second pressure valve has two main functions: Firstly, when steam enters the second fixed rod 209 through the transmission pipe 201 and the third pipe 208, causing the second telescopic rod 210 to extend and make the clamping plate 211 fully contact the paper roll on the drive roller and both sides of the paper drum, the internal air pressure of the second fixed rod 209 no longer rises. When the second pressure valve detects that the pressure inside each group of second fixed rods 209 tends to be balanced, it will automatically close the passage of each group of third pipes 208, thereby maintaining the pressure balance of each group of second fixed rods 209. The internal air pressure of the second fixing rod 209 is stable, ensuring that each set of second telescopic rods 210 can stably clamp the paper roll and both sides of the paper drum through each set of clamping plates 211. On the other hand, if the steam inside each set of second fixing rods 209 turns into liquid, causing the air pressure to drop, the second pressure valve on each set of third pipes 208 will automatically open, allowing steam to be transmitted to the inside of the second fixing rods 209 through the third pipes 208, replenishing the internal air pressure in time, and continuously ensuring the stability of each set of clamping plates 211 in clamping the paper roll and both sides of the paper drum of each set of drive rollers.

[0030] In an optional embodiment, one side of each set of second fixing rods 209 is fixedly connected to the unwinding machine 1, and the other side of each set of second fixing rods 209 is connected to a fourth pipe 213, and each set of fourth pipes 213 is provided with a second solenoid valve.

[0031] It should be noted that when each set of first fixed rods 203 is not in operation, each set of second telescopic rods 210 is in a retracted state inside each set of second fixed rods 209. At this time, the second pressure valve on each set of third pipes 208 is open, and the second solenoid valve on each set of fourth pipes 213 is closed. Therefore, another part of the steam is transmitted to the inside of each set of third pipes 208 through both ends of each set of transmission pipes 201. When the unwinding machine 1 has finished unwinding, the steam engine is turned off, and the steam engine no longer transmits steam to the inside of each set of second fixed rods 209 through each set of transmission pipes 201. Steam is supplied. The staff opens the second solenoid valve on the fourth pipe 213 of each group. The steam inside the second fixed rod 209 of each group is discharged through the fourth pipe 213 of each group. At this time, the fourth pipe 213 inside the fourth pipe 213 of each group is no longer under the pressure of steam. The second spring 212 of each group drives the second telescopic rod 210 of each group to rebound, so that the second telescopic rod 210 of each group moves the clamping plate 211 away from the paper roll and paper drum sides of each group of drive rollers. The staff reinstalls the paper roll and paper drum of the two groups of drive rollers and performs the paper unwinding operation again.

[0032] In an optional embodiment, each set of second fixing rods 209 is provided with a second spring 212 inside, one end of each set of second springs 212 is fixedly connected to the inside of the second fixing rod 209, and the other end of each set of second springs 212 is fixedly connected to the other end of the second telescopic rod 210.

[0033] It should be noted that the fourth pipe 213 inside each group of fourth pipes 213 is no longer under the pressure of steam. The second spring 212 of each group drives the second telescopic rod 210 of each group to rebound, so that the second telescopic rod 210 of each group drives the clamping plate 211 away from the paper roll and paper drum sides of each group of drive rollers. The workers reinstall the paper roll and paper drum of the two groups of drive rollers and perform the paper unwinding work again.

[0034] In an optional embodiment, the unwinder 1 has grooves on both sides, and the two ends of the tension rod 303 pass through the two sets of grooves respectively. Both ends of the tension rod 303 are slidably connected to the grooves. The two ends of the tension rod 303 are connected to the fifth pipe 305, and one end of each set of the fifth pipe 305 is connected to one end of each set of transmission pipes 201.

[0035] It should be noted that when the two sets of cylinders 301 drive the tension rod 303 to move on the groove of the unwinder 1, the fifth pipe 305 is used to transfer a portion of the steam into the tension rod 303 when adjusting the tension of the paper.

[0036] Working principle: The operator places the paper roll and the empty paper drum onto the two sets of drive rollers of the unwinding machine 1 respectively. The operator then installs the two sets of drive rollers onto the clamps on both sides of the unwinding machine 1. Each set of clamps is locked by the fixing nuts on each set of clamps. Then the operator starts the motor. The motor is driven by the gear set and drives the drive roller with the paper roll to rotate, starting the unwinding process. The paper is collected again on the drive roller with the paper drum installed after passing through multiple sets of transfer rollers and auxiliary transfer wheels. In winter, when the paper roll is unwound on the unwinding machine 1, the operator starts the steam engine connected to the air inlet of one set of transmission pipes 201. The steam engine transmits steam into the interior of one set of transmission pipes 201. One set of transmission pipes 201 transmits steam to the interior of another set of transmission pipes 201 through the connecting pipe 214. The two sets of transmission pipes 201 transmit steam together. Since the first fixed rod 203 of each set is not working, the first telescopic rod 204 of each set is in a retracted state inside the first fixed rod 203 of each set. At this time, the first pressure valve on the first pipe 202 of each set is in an open state, and the first solenoid valve on the second pipe 207 of each set is closed. Therefore, each set of transmission pipes 201 transmits a part of the steam into the interior of each set of first fixed rods 203. The steam drives the first spring 206 of each set and the first telescopic rod 204 of each set to extend. The first telescopic rod 204 of each set drives the fixed frame 205 to extend. The fixed frame 205 of each set extends to the fixed nut of each set of clamps, and fixes the fixed nut on the clamp. While a portion of the steam is being transmitted into the interior of each set of first fixed rods 203, since each set of first fixed rods 203 is not in operation, each set of second telescopic rods 210 is in a retracted state inside each set of second fixed rods 209. At this time, the second pressure valve on each set of third pipes 208 is open, and the second solenoid valve on each set of fourth pipes 213 is closed. Therefore, another portion of the steam is transmitted through both ends of each set of transmission pipes 201 to the interior of each set of third pipes 208. Each set of third pipes 208 transmits the steam to the interior of each set of second fixed rods 209. The steam drives each set of second springs 212 and each set of second telescopic rods 210 to extend. Each set of second fixed rods 209 drives each set of clamping plates 211 to clamp the paper roll and paper drum on both sides of each set of driven rollers, thus fixing the paper roll and paper drum on both sides of each set of driven rollers. When the operator starts the two sets of cylinders 301, the two sets of cylinders 301 drive the tension rod 303 to move on the groove of the unwinder 1. When adjusting the tension of the paper, at the same time, another part of the steam is transmitted through both ends of each set of transmission pipes 201 to the inside of each set of second fixed rods 209. At the same time, another part of the steam is transmitted through both ends of each set of transmission pipes 201 to the inside of each set of fifth pipes 305. Each set of fifth pipes 305 transmits the steam together to the inside of the tension rod 303, and sprays it onto the paper surface through the exhaust hole 304 to soften the paper surface.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
