Description

Technical Field

[0001] The present application relates to the technical field of paper processing equipment, and in particular to a paper rolling device. Background Art

[0002] The paper tube is a cylindrical tube structure, and is often used as the supporting core tube inside the roll paper. The processing of the paper tube is mainly formed by rolling the paper into a roll using a roll forming machine.

[0003] The most common roll forming machine is the spiral roll forming machine, which mainly includes a bracket, a core shaft, a paper delivery rack and a driving device. The core shaft is horizontally fixedly connected to the bracket, and the paper delivery rack is installed on the bracket and is located on one side of the core shaft to guide the movement of the paper. One end of the paper passes through the paper delivery rack and is wound around the core shaft to form a paper tube. The driving assembly is installed on the bracket to drive the paper tube to rotate and move toward the end of the core shaft. The common driving device mainly winds a belt set at an angle to the length direction of the core shaft around the paper tube. Under the action of friction, the belt can drive the paper tube to rotate and move when it rotates, thereby realizing a continuous roll.

[0004] When the paper roll rotates and slides relative to the core shaft, friction will also be generated between the paper roll and the core shaft. When the friction between the paper roll and the core shaft is large, on the one hand, the friction between the paper roll and the core shaft generates a high temperature, and on the other hand, it will make it difficult for the paper roll to separate from the core shaft. Therefore, the paper spiral winding machine in the related art has poor stability during operation. Utility Model Content

[0005] In order to reduce the friction between the paper roll and the core shaft and improve the stability of the spiral rolling machine during operation, the present application provides a paper rolling device.

[0006] The paper rolling device provided in this application adopts the following technical solution:

[0007] A paper rolling device comprises a spiral rolling machine, wherein the spiral rolling machine is provided with a lubricating device, wherein the lubricating device comprises a support rod and an oil dripping piece, wherein the support rod is vertically mounted on the spiral rolling machine, and the oil dripping piece is mounted on the support rod, wherein the oil dripping piece is located directly above the contact paper, and the oil dripping piece is used to store lubricating oil, wherein the oil dripping piece is provided with an oil outlet, and the lubricating oil stored in the oil dripping piece can be continuously discharged from the oil outlet.

[0008] By adopting the above technical scheme, here, the paper tube is formed by rolling a plurality of strips of paper. After the plurality of strips of paper are rolled, part of them are in contact with the already formed paper tube, and part of them are in contact with the core shaft; the forming principle is specifically described in the embodiment. The contact paper refers to the strip of paper that contacts the core shaft after the paper is rolled into a paper tube. During the operation of the rolling device, the plurality of strips of paper are continuously wound around the core shaft. While the plurality of strips of paper are moving, the oil outlet of the oil dripping part discharges lubricating oil, and the lubricating oil drips onto the contact paper under the action of gravity. After the plurality of strips of paper are rolled into a paper tube, the contact paper contacts the core shaft, and the lubricating oil forms an oil film between the strips of paper and the core shaft, thereby reducing the friction between the paper tube and the core shaft, and facilitating the separation of the paper tube and the core shaft.

[0009] Optionally, an adjustment mechanism is provided between the support rod and the oil dripping member, the adjustment mechanism comprises a vertical cylinder, the vertical cylinder is slidably sleeved on the support rod along the length direction of the support rod, and the oil dripping member is mounted on the vertical cylinder.

[0010] By adopting the above technical solution, in the actual production process, multiple strips of paper are arranged at intervals in the vertical direction in front of multiple strips of paper rolls. Different types of paper rolls correspond to different numbers of strips of paper. Therefore, when processing different paper rolls, the height of the contact paper is different. The oil dripping part can be driven to move by sliding the vertical cylinder, thereby changing the position of the vertical cylinder in the vertical direction. The lubrication device can adapt to the processing and production of different paper rolls.

[0011] Optionally, the adjustment mechanism further includes a horizontal adjustment component, which is installed on the vertical cylinder and is used to adjust the position of the oil dripping member in the horizontal direction.

[0012] By adopting the above technical solution, multiple strips of paper are arranged in an interlaced manner, that is, the projections of multiple strips of paper on the horizontal plane do not overlap. Therefore, according to the different types of paper tubes produced, the overlapping areas of the strips of paper are different, resulting in different positions of the contacting paper in the horizontal direction. The horizontal position of the oil dripping piece is adjusted by the horizontal adjustment component, further improving the application range of the lubrication device.

[0013] Optionally, the horizontal adjustment assembly includes an adjustment rod and a horizontal cylinder, the horizontal cylinder is horizontally arranged on one side of the vertical cylinder, one end of the adjustment rod is horizontally slidably inserted into the horizontal cylinder, and the oil dripping member is installed on the adjustment rod.

[0014] By adopting the above technical solution, the sliding adjustment rod can drive the oil dripping piece to move, thereby realizing the adjustment of the position of the oil dripping piece in the horizontal direction.

[0015] Optionally, the adjustment mechanism further includes two locking members, which are respectively arranged corresponding to the horizontal cylinder and the vertical cylinder, and are used to limit the sliding of the vertical cylinder and the adjustment rod.

[0016] By adopting the above technical solution, after the position adjustment of the vertical cylinder and the adjusting rod is completed, the locking member can be used to limit the position of the vertical cylinder and the adjusting rod, thereby improving the stability of the oil dripping member during use and improving the oil dripping effect.

[0017] Optionally, the oil dripping member is provided in plurality along the length direction of the support rod, and the adjusting mechanism is provided in plurality corresponding to the oil dripping member.

[0018] By adopting the above technical solution, multiple oil dripping parts drip oil on different positions contacting the paper, thereby improving the uniformity of lubricating oil distribution, improving the lubrication effect, and further facilitating the separation of the paper roll from the core shaft. In addition, multiple oil dripping parts can be used alternately, for example: multiple oil dripping parts store lubricating oil, and when the reel device is working, some oil dripping parts drip oil on the contacting paper. When the lubricating oil in the oil dripping parts is consumed, the oil outlets of other oil dripping parts are opened, and the oil dripping parts whose lubricating oil has been consumed are replaced at the same time, so that the reel device can work continuously.

[0019] Optionally, the horizontal adjustment assembly includes a fixed block, a sliding rod and an adjusting ring, the fixed block is mounted on a vertical cylinder, a sliding hole is horizontally penetrated through the vertical cylinder, the sliding rod slides horizontally through the sliding hole, the oil dripping piece is mounted on the sliding rod, the adjusting ring is rotatably connected to the fixed block and is threadedly connected to the sliding rod, and rotating the adjusting ring can drive the sliding rod to move.

[0020] By adopting the above technical solution, rotating the adjusting ring can drive the slide bar to move, thereby adjusting the position of the oil dripping piece. Moreover, since the thread has self-locking property, the position of the slide bar is not easy to move after the adjusting ring stops rotating, thereby improving the stability of the oil dripping piece during use.

[0021] Optionally, a limiting plane is provided on the sliding rod, and a fitting surface that fits with the limiting plane is provided on the side wall of the sliding hole.

[0022] By adopting the above technical solution, the limiting plane is in contact with the contact surface, thereby preventing the sliding rod from rotating, reducing the sliding rod from rotating along with the adjusting ring during the rotation of the adjusting ring, and improving the stability of the oil dripping member during the horizontal position adjustment process. In addition, the oil removal hole of the oil dripping member can be relatively fixed, thereby improving the accuracy of oil dripping of the oil dripping member.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] Before the strip of paper is wound on the core shaft, the oil dripping piece sprays lubricating oil onto the contact paper. The lubrication reduces the friction between the paper tube and the core shaft formed after the strip of paper is wound on the core shaft, thereby facilitating the separation of the paper tube and the core shaft and improving the stability of the paper tube during movement and rotation.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] Reference Figure 1 The core shaft 11 of the spiral winding machine 1 includes a discharge end and a feed end, and the feed end is fixedly connected to the bracket of the spiral winding machine 1. The discharge end of the core shaft 11 is suspended in the air, and the paper tube 12 can be separated from the core shaft 11 by the discharge end. During the processing of the paper tube 12, a plurality of strips of paper are arranged in the vertical direction and tilted toward the direction of the feed end close to the core shaft 11. The projections of the plurality of strips of paper on the horizontal plane overlap, and the plurality of strips of paper are wound around the core shaft 11 after passing through the paper delivery rack at the same time. After the plurality of strips of paper contact the core shaft 11 at the same time, since the paper itself is a thin sheet structure, the plurality of strips of paper can be regarded as a whole at this time, that is, the plurality of strips of paper form a paper with a larger width near the core shaft 11. For the convenience of description, the paper formed by the plurality of strips of paper is defined as a wide paper. During the winding process of the wide paper, the position of the wide paper away from the discharge end of the core shaft 11 is in contact with the core shaft 11, and the remaining part is in contact with the side of the already formed paper tube 12 (it can also be understood that among the multiple strips of paper, the strips of paper away from the discharge end of the core shaft 11 can contact the core shaft 11, and the friction between the paper tube 12 and the core shaft 11 is mainly formed by the strips of paper away from the discharge end of the core shaft 11 and the core shaft 11); thereby increasing the thickness of the paper tube 12 and improving the structural strength of the paper tube 12.

[0032] The embodiment of the present application discloses a paper rolling device.

[0033] Example 1

[0034] Reference Figure 1 A paper rolling device includes a spiral rolling machine 1 and a lubricating device 2. The lubricating device 2 includes a support rod 21 and an oil dripping member 22. The support rod 21 is a cylindrical rod-shaped structure. The support rod 21 is vertically fixed to the spiral rolling machine 1 by screws. The oil dripping member 22 is installed on the support rod 21, and the oil dripping member 22 is located directly above the contact paper 13 (for the convenience of description, in this embodiment, the strip of paper that actually contacts the core shaft 11 after the paper tube 12 is formed is defined as the contact paper 13, that is, the paper in the multiple strips of paper that is far away from the discharge end of the core shaft 11). The oil dripping member 22 is used to store lubricating oil and drip lubricating oil to the side of the contact paper 13 that contacts the core shaft 11. The lubricating oil reduces the friction between the paper tube 12 and the core shaft 11, thereby reducing the instability caused by the friction during the movement or rotation of the paper tube 12, and facilitating the separation of the paper tube 12 from the core shaft 11.

[0035] Reference Figure 1 and Figure 2 In this embodiment, the oil dripping member 22 is a needle valve type oil cup, and the oil outlet of the needle valve type oil cup is vertically oriented toward the contact paper 13. Under the action of gravity, the lubricating oil in the needle valve type oil cup gradually drips onto the contact paper 13, thereby achieving lubrication between the paper tube 12 and the core shaft 11. In addition, the needle valve of the needle valve type oil cup can be adjusted as needed, thereby adjusting the oil dripping speed of the needle valve type oil cup, thereby improving the lubrication effect of the lubricating device 2.

[0036] Reference Figure 1 and Figure 2 An adjusting mechanism 3 is provided between the oil dripping member 22 and the supporting rod 21, and the adjusting mechanism 3 is used to adjust the position of the oil dripping member 22 in the horizontal direction and the vertical direction, so that the lubricating device 2 can adapt to the lubrication of different types of paper tubes 12 in the actual processing and production process.

[0037] Reference Figure 1 and Figure 2 The adjustment mechanism 3 includes a vertical cylinder 31 and a horizontal adjustment component 4. The vertical cylinder 31 is a cylindrical structure. The vertical cylinder 31 is slidably mounted on the support rod 21 along the length direction of the support rod 21, and the vertical cylinder 31 can rotate along its own axis. The horizontal adjustment component 4 is installed on the vertical cylinder 31, and the oil dripping piece 22 is installed on the horizontal adjustment component 4. The sliding vertical cylinder 31 can drive the horizontal adjustment component 4 to move in the vertical direction, thereby driving the adjustment of the position of the oil dripping piece 22 in the vertical direction. The horizontal adjustment component 4 is used to adjust the position of the oil dripping piece 22 in the horizontal direction.

[0038] Reference Figure 1 and Figure 2The horizontal adjustment assembly 4 includes a horizontal cylinder 41 and an adjustment rod 42. The horizontal cylinder 41 is a circular cylindrical structure, and the vertical horizontal cylinder 41 is located on one side of the vertical cylinder 31. The length direction of the horizontal cylinder 41 is perpendicular to the length direction of the vertical cylinder 31, and the outer wall of the horizontal cylinder 41 is welded to the outer wall of the vertical cylinder 31. The adjustment rod 42 is a cylindrical rod structure, and the adjustment rod 42 is slidably arranged in the horizontal cylinder 41 along the length direction of the horizontal cylinder 41. The oil dripping piece 22 is fixedly connected to the end of the adjustment rod 42 away from the horizontal cylinder 41 by screws. The position of the oil dripping piece 22 in the horizontal and vertical directions is adjusted by sliding the vertical cylinder 31 and the adjustment rod 42.

[0039] Reference Figure 1 and Figure 2 The adjustment mechanism 3 also includes two locking members 32, which are arranged corresponding to the horizontal cylinder 41 and the vertical cylinder 31. The locking members 32 are used to limit the position of the vertical cylinder 31 or the adjustment rod 42. The locking members 32 have the same limiting principle on the adjustment rod 42 or the vertical cylinder 31. In this embodiment, the limiting of the adjustment rod 42 by the locking member 32 is described, and the locking member 32 includes a locking screw and a knob. A threaded hole is provided on the outer wall of the horizontal cylinder 41, and the threaded hole is connected to the inside of the horizontal cylinder 41. The threaded rod is threadedly connected in the threaded hole, and the knob is welded to the end of the threaded rod away from the adjustment rod 42. Turning the knob can drive the threaded rod to rotate, and under the action of the thread, the threaded rod can make one end of itself close to the adjustment rod 42 press against the adjustment rod 42, thereby limiting the relative displacement between the adjustment rod 42 and the horizontal cylinder 41, and improving the stability of the oil dripping member 22 during use.

[0040] Reference Figure 1 and Figure 2 , a plurality of oil dripping members 22 are provided, and the plurality of oil dripping members 22 are arranged at intervals in the vertical direction. The adjustment mechanism 3 is provided with a plurality of oil dripping members 22 corresponding to the oil dripping members 22. The plurality of oil dripping members 22 can simultaneously drip lubricating oil to different positions contacting the paper 13, so that the lubricating oil is distributed more evenly. In addition, the plurality of oil dripping members 22 can be used alternately, so as to avoid the equipment downtime caused by the need to add lubricating oil in the oil dripping members 22, and improve the production efficiency of the winding device.

[0041] The implementation principle of a paper rolling device in the embodiment of the present application is as follows: during the operation of the rolling device, the oil outlet of the needle valve oil cup is opened, and as the paper roll 12 rotates, the strip of paper is wound around the core shaft 11. During the movement of the strip of paper, the needle valve oil cup drips lubricating oil onto the contact paper 13. As the contact paper 13 is wound around the core shaft 11, the lubricating oil forms an oil film between the paper roll 12 and the core shaft 11, thereby reducing the friction between the paper roll 12 and the core shaft 11, and facilitating the separation of the paper roll 12 from the core shaft 11.

[0042] Example 2

[0043] Reference Figure 3 and Figure 4 , the difference between this embodiment and embodiment 1 is that the structure of the horizontal adjustment component 4 is different. In this embodiment, the horizontal adjustment component 4 includes a fixed block 43, an adjustment ring 44 and a slide bar 45. The fixed block 43 is a cylindrical structure, and the fixed block 43 is welded on one side of the vertical cylinder 31. A sliding hole is provided on the fixed block 43 along its own length direction, and the slide bar 45 is inserted in the sliding hole and can slide along its own length direction. The adjustment ring 44 is a circular ring structure, and the adjustment ring 44 is connected to the fixed block 43 by rotation around its own axis. In addition, the adjustment ring 44 is sleeved on the outside of the slide bar 45, and an internal thread is provided on the inner side wall of the adjustment ring 44, and a thread groove matching the internal thread is provided on the side of the slide bar 45. Rotating the adjustment ring 44 can drive the slide bar 45 to move in the horizontal direction, thereby realizing the adjustment of the position of the oil dripping piece 22 in the horizontal direction. Moreover, due to the self-locking property of the thread, the slide bar 45 is not easy to move after the position is adjusted, thereby improving the stability of the oil dripping piece 22 during use.

[0044] Reference Figure 3 and Figure 4 A limiting plane 46 is provided on the side wall of the slide bar 45, and a fitting surface that cooperates with the limiting plane 46 is provided in the sliding hole. The limiting plane 46 fits with the fitting surface to limit the rotation of the slide bar 45, thereby reducing the rotation of the slide bar 45 during the use of the oil dripping member 22 or during the process of adjusting the position of the slide bar 45, and further improving the stability of the oil dripping member 22 during use. In order to improve the stability of the limiting plane 46 on the rotation of the slide bar 45, two limiting planes 46 are provided, and the two limiting planes 46 are parallel to each other. Two limiting planes 46 corresponding to the fitting surface are provided.

[0045] The implementation principle of a paper rolling device in an embodiment of the present application is: rotating the adjusting ring 44, driving the slide bar 45 to move under the action of the adjusting ring 44, and then driving the oil dripping member 22 to move, so as to adjust the horizontal position of the oil dripping member 22.
