Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, specifically to a device for a release agent in a precision paper drying cylinder for hand towels. Background Technology

[0002] Paper machine dryer cylinders often accumulate paper fibers and adhesive residue on the scraper blades, which not only easily leads to paper breakage and reduced production efficiency but also affects product quality, causing problems such as rotten paper and holes. A dryer cylinder release agent device solves this problem. Compressed air atomizes the release agent, spraying it onto the surface of the dryer cylinder of the hand towel paper machine, at a distance of approximately 10-15 cm. A chain drive mechanism drives the nozzles in a reciprocating motion, ensuring the release agent is evenly sprayed back and forth on the cylinder surface. However, due to the large amount of release agent used, oil stains are often left on the paper surface, causing customer quality complaints. Furthermore, the large amount of release agent used, and the fact that the release agent contains a large amount of waste emulsified machine oil, also frequently leads to customer complaints about the oily smell of the hand towels, resulting in returns.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese Patent Publication No. CN205856926U, Publication Date 2017-01-04) discloses a paper release agent spraying device, comprising a frame, a slide rail parallel to the drying cylinder on the frame, a mounting seat slidably mounted on the slide rail, a sliding drive device for driving the mounting seat to reciprocate on the slide rail between the frame and the mounting seat, a nozzle facing the drying cylinder mounted on the mounting seat, and a release agent supply device mounted on the frame, connected to the nozzle via a connecting hose. This device enables automatic spraying of the release agent, thereby improving work efficiency. Applying the release agent by spraying not only ensures uniform coating but also saves on release agent. During the spraying of the release agent, paper dust adhering to the drying cylinder can be removed, ensuring the surface of the drying cylinder is clean and improving the quality of the finished paper.

[0004] The aforementioned mechanism supplies the stripping agent through a reciprocating sliding drive device. However, in actual use, spraying with only one nozzle will result in a slow supply of stripping agent, which in turn will cause the supply of stripping agent to be unable to keep up with the overall production process. Utility Model Content

[0005] The purpose of this utility model is to provide a release agent device for the precision paper drying cylinder of hand towels, so as to solve the problems mentioned in the background art, which are that due to the large amount of release agent used, oil spots are often left on the paper surface, causing customer quality complaints. Also, due to the large amount of release agent used and the large amount of waste emulsified machine oil contained in the release agent, customer complaints about the smell of machine oil in the hand towels are also common, leading to returns.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for removing a release agent from a precision paper drying cylinder for hand towels, comprising a fixed base plate, a guide rail mounted on the rear end of the top of the fixed base plate, and a mounting bracket slidably connected inside the guide rail, a spray pipe engaged on the inner side of the mounting bracket, nozzles evenly distributed at the front end of the spray pipe, a drive motor mounted on the top of the fixed base plate on the right side of the spray pipe, and an eccentric wheel mounted on the output end of the drive motor; a dosing pipe mounted on the side of the spray pipe, and a docking mechanism for reducing gaps mounted on the side of the dosing pipe; a fixed plate mounted on the left side of the top of the fixed base plate, and a buffer mechanism for preventing uneven spraying due to excessive movement speed mounted on the side of the fixed plate, the buffer mechanism comprising a guide rod, and the guide rod being fixedly connected to the upper and lower ends of the left side of the spray pipe, one side of the guide rod passing through and extending to the left side of the fixed plate.

[0007] Furthermore, dampers are installed at both the front and rear ends of the left side of the spray pipe, and the left side of the dampers is connected to the fixing plate.

[0008] Furthermore, a buffer spring is wound around the outside of the guide rod, and the guide rod forms an elastic structure with the fixed plate through the buffer spring.

[0009] Furthermore, a positioning mechanism is installed at each of the four corners of the bottom of the fixed base plate. The positioning mechanism includes a fixing rod, which is fixedly connected to the four corners of the bottom of the fixed base plate. A suction cup is installed at the bottom of the fixing rod, and a piston is vertically slidably connected inside the fixing rod. A pull rod is fixedly connected to the top of the piston, and the top of the pull rod passes through and extends to the top of the fixed base plate.

[0010] Furthermore, a connecting spring is wound around the outside of the pull rod, and a sealing gasket is attached above the vent hole at the top of the fixed base plate, with the top of the sealing gasket connected to the bottom of the connecting spring.

[0011] Furthermore, each of the four corners at the top of the fixed base plate is provided with an exhaust hole, and the position of the exhaust hole corresponds to the position of the fixed rod.

[0012] Furthermore, the docking mechanism includes a limiting box, which is sleeved on the outside of the dosing tube. The dosing tube is internally engaged with a connecting pipe, and the limiting box is fixedly connected to the outside of the connecting pipe. A first airbag is installed on the left side inside the limiting box, and a compression plate is attached to the right side of the first airbag. A second airbag is attached to the right side of the compression plate, and the inner side of the second airbag is attached to the outer side of the dosing tube.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By using the output end of the drive motor to drive the eccentric wheel to rotate, the eccentric wheel can continuously push the spray pipe to the left. The spray pipe can achieve its reciprocating motion through the buffer mechanism set on the left. The multiple nozzles set on the surface of the spray pipe can evenly spray the stripping agent onto the drying cylinder. The reciprocating motion of the spray pipe can effectively prevent the excessive application of stripping agent.

[0015] Furthermore, the nozzles are replaced with one-fluid nozzles for micro-spraying, saving on the stripper agent and preventing accumulation, dripping, and contamination. After replacement, the nozzles do not require compressed air, and each nozzle has its own filter to prevent impurities in the stripper agent from clogging the nozzle. Holes can be drilled in the stripper agent spray pipe, and the nozzles can be installed after drilling. The nozzle spacing is 210 mm, and the eccentric wheel swing distance is 10 mm, making the sprayed stripper agent more uniform.

[0016] Furthermore, a guide rod is installed on the side of the spray pipe. The guide rod passes through the fixed plate and a buffer spring is wound around the outside of the guide rod. When the spray pipe is pushed, the buffer spring is stressed and shortens its length. At the same time, the guide rod passes through the fixed plate and extends to the other side of the fixed plate. Then, through the damper, the spray pipe can slowly return to its original position, avoiding uneven spraying caused by excessive movement speed during the reciprocating motion of the spray pipe.

[0017] 2. By applying pressure to the fixed base plate and the pull rod, some of the air inside the pull rod is expelled through the suction cup. The pressure from the fixed base plate also expels the air from the suction cup. The positioning mechanism ensures greater stability of the device and effectively prevents the device from shaking due to the reciprocating rotation of the eccentric wheel.

[0018] Furthermore, when the dosing tube and the connecting tube are connected, the side of the dosing tube squeezes the extrusion plate, which causes the extrusion plate to apply pressure evenly to the first airbag. This allows the gas inside the first airbag to be delivered to the inside of the second airbag. The second airbag can fill the remaining gap between the dosing tube and the connecting tube from the outside, thus effectively preventing gaps from forming during connection and causing the release agent to leak.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figure 1 , Figure 2 and Figure 3The technical solution presented addresses the issues of oil stains frequently left on the paper surface due to the large amount of release agent used, leading to customer quality complaints. It also addresses the frequent customer complaints about the oily odor in hand towels, resulting in returns, due to the large amount of release agent used and the presence of a large amount of waste emulsified machine oil in the release agent. The disclosed release agent device for the precision paper drying cylinder of hand towels includes a reciprocating spraying mechanism, comprising a fixed base plate 1, a guide rail 2 mounted at the rear end of the top of the fixed base plate 1, and a mounting frame 3 slidably connected inside the guide rail 2. A spray pipe 4 is engaged with the inner side of the mounting frame 3, and nozzles 5 are evenly distributed at the front end of the spray pipe 4. A drive motor 8 is mounted on the top of the fixed base plate 1 on the right side of the spray pipe 4. Furthermore, an eccentric wheel 9 is installed at the output end of the drive motor 8; a fixed plate 10 is installed on the left side of the top of the fixed base plate 1, and a buffer mechanism for preventing uneven spraying caused by excessive movement speed is installed on the side of the fixed plate 10. The buffer mechanism includes a guide rod 11, and the guide rod 11 is fixedly connected to the upper and lower ends of the left side of the spray pipe 4. One side of the guide rod 11 passes through and extends to the left side of the fixed plate 10; dampers 13 are installed at both the front and rear ends of the left side of the spray pipe 4, and the left side of the damper 13 is connected to the fixed plate 10; a buffer spring 12 is wound around the outside of the guide rod 11, and the guide rod 11 forms an elastic structure with the fixed plate 10 through the buffer spring 12.

[0028] In this example, the output of the drive motor 8 drives the eccentric wheel 9 to rotate, which continuously pushes the spray pipe 4 to the left. The spray pipe 4, through a buffer mechanism on the left, reciprocates. Multiple nozzles 5 on the surface of the spray pipe 4 evenly spray the stripping agent onto the drying cylinder. The reciprocating motion of the spray pipe 4 effectively prevents excessive application of the stripping agent, increasing overall stability during use. After replacement, the nozzle 5 can be of model B1 / 4Q11A-SS+QWA-SS1101. The nozzle 5 uses a one-fluid nozzle for micro-spraying, saving stripping agent, preventing accumulation, dripping, and contamination. After replacement, the nozzle 5 does not require compressed air; each nozzle has a built-in filter to prevent impurities in the stripping agent from clogging the nozzle. Holes can be drilled in the stripping agent spray pipe, which is [length missing]. The nozzle is 2 inches in diameter and made of 316SS stainless steel. After drilling, the nozzle is installed with a spacing of 210 mm and an eccentric wheel swing distance of 10 mm to make the sprayed stripper more uniform. A guide rod 11 is installed on the side of the spray pipe 4. The guide rod 11 passes through the fixed plate 10 and a buffer spring 12 is wound around the outside of the guide rod 11. When the spray pipe 4 is pushed, the buffer spring 12 is stressed and shortens its length. At the same time, the guide rod 11 passes through the fixed plate 10 and extends to the other side of the fixed plate 10. Then, through the damper 13, the spray pipe 4 can slowly return to its original position, avoiding uneven spraying caused by excessive movement speed during the reciprocating motion of the spray pipe 4. Furthermore, the spray pipe 4 slides inside the guide rail 2 through the mounting bracket 3. The sliding connection between the guide rail 2 and the mounting bracket 3 makes the movement of the spray pipe 4 more stable and effectively avoids shaking.

[0029] Example 2: Figure 1 , Figure 2 , Figure 4 and Figure 6 The technical solution shown addresses the problem of potential device displacement caused by continuous repositioning of the spray pipe 4. The device for removing the release agent from the precision paper drying cylinder of the hand towel includes a positioning mechanism. Positioning mechanisms are installed at the four corners of the bottom of the fixed base plate 1. Each positioning mechanism includes a fixed rod 14, which is fixedly connected to the four corners of the bottom of the fixed base plate 1. A suction cup 15 is installed at the bottom of the fixed rod 14, and a piston 16 is vertically slidably connected inside the fixed rod 14. A pull rod 17 is fixedly connected to the top of the piston 16, and the top of the pull rod 17 passes through and extends to the top of the fixed base plate 1. A connecting spring 20 is wound around the outside of the pull rod 17. A sealing gasket 19 is attached above the vent hole 18 at the top of the fixed base plate 1, and the top of the sealing gasket 19 is connected to the bottom of the connecting spring 20. Vent holes 18 are provided at the four corners of the top of the fixed base plate 1, and the positions of the vent holes 18 correspond to the positions of the fixed rods 14.

[0030] In this example, to prevent the device from shifting position due to the reciprocating rotation of the eccentric wheel 9 during use, a positioning mechanism is used to ensure greater stability and effectively prevent the device from shaking due to the impact of the reciprocating rotation of the eccentric wheel 9. By applying pressure to the fixed base plate 1 and simultaneously applying pressure to the pull rod 17, some of the gas inside the pull rod 17 is expelled through the suction cup 15. The pressure from the fixed base plate 1 further expels the air from the suction cup 15, thus achieving basic adsorption. To prevent incomplete venting during the venting process, pressing the pull rod 17 further ensures that the air inside the suction cup 15 is expelled. When the spring 20 is stressed and shortens in length, the piston 16 at the bottom of the pull rod 17 moves downwards and squeezes out the air inside the suction cup 15, thereby effectively reducing the amount of air remaining inside the suction cup 15. At the same time, when there is air remaining inside the fixed rod 14, when the pull rod 17 and piston 16 are reset by the elastic force of the connecting spring 20, the piston 16 will squeeze the air at the upper end of the fixed rod 14 and discharge it from the exhaust port 18. After the air inside the fixed rod 14 is discharged, the sealing gasket 19 will automatically reset by the elastic force of the connecting spring 20 and block the exhaust port 18, thereby completing the discharge of air inside the fixed rod 14.

[0031] Example 3: Figure 1 , Figure 2 , Figure 4 and Figure 5 The technical solution shown addresses the potential issue of insufficient tightness in the connection between the dosing tube 6 and the connecting tube 7 during pipe connection. The paper towel precision paper drying cylinder release agent device discloses a docking mechanism. The dosing tube 6 is installed on the side of the spray pipe 4, and a docking mechanism for reducing gaps is installed on the side of the dosing tube 6. The docking mechanism includes a limiting box 21, which is fitted onto the outside of the dosing tube 6. The connecting tube 7 is internally engaged with the dosing tube 6, and the limiting box 21 is fixedly connected to the outside of the connecting tube 7. A first airbag 22 is installed on the left side inside the limiting box 21, and a pressure plate 23 is attached to the right side of the first airbag 22. A second airbag 24 is attached to the right side of the pressure plate 23, and the inner side of the second airbag 24 is attached to the outer side of the dosing tube 6.

[0032] In this example, when the dosing tube 6 and the connecting tube 7 are connected, the side of the dosing tube 6 presses against the extrusion plate 23, which causes the extrusion plate 23 to apply pressure evenly to the first airbag 22. This allows the gas inside the first airbag 22 to be delivered to the inside of the second airbag 24. The second airbag 24 can fill the remaining gap between the dosing tube 6 and the connecting tube 7 from the outside, thus effectively preventing gaps from appearing during connection and causing the release agent to leak, and increasing the stability of the release agent delivery.
