Description

Technical Field

[0001] This application relates to the field of tissue paper production, and in particular to an online adjustment folding system and the folding tissue paper thereof. Background Technology

[0002] Paper towels are a common household item, and there are many different types. Currently, the main raw material for making paper towels is pulp, which is a fibrous material made from plant fibers through various processing methods. Paper towel products typically offer two dispensing methods: continuous dispensing and non-continuous dispensing.

[0003] Patent application CN119370667A discloses a fully automatic point-break continuous tissue folding production line, which is mainly capable of producing tissues with point-break knife marks and folds, so that when the tissues are pulled out, after the previous tissue is pulled out, the next tissue can be pulled out with one corner, thus facilitating the use of the tissues.

[0004] However, due to the different materials and application scenarios of paper towels, it is often necessary to set different spacings between the cut marks and creases to meet the needs of different usage situations. The above-mentioned technical solutions are difficult to quickly adjust the production of different spacings between the cut marks and creases of paper towels according to different production requirements. Utility Model Content

[0005] To facilitate rapid production adjustments of different spacing between the cut marks and creases of tissue paper according to varying production requirements, this application provides an online folding adjustment system.

[0006] In a first aspect, this application provides an online adjustment folding system, which adopts the following technical solution:

[0007] An online adjustment folding system includes a breakpoint assembly, a crease assembly, and a drive assembly mounted on a frame. The breakpoint assembly includes a breakpoint roller and a breakpoint auxiliary roller, which are arranged side-by-side and used to perform breakpoint processing on tissue paper. The crease assembly includes a first crease roller and a second crease roller, which are arranged side-by-side and used to perform crease processing on tissue paper. The drive assembly drives the breakpoint roller, the breakpoint auxiliary roller, the first crease roller, and the second crease roller to rotate. The drive assembly includes an auxiliary gear, a first internal gear, a first external gear, and a second gear. The auxiliary gear is coaxially fixedly mounted on the breakpoint auxiliary roller. The first internal gear is coaxially rotatably mounted on the first crease roller and meshes with the auxiliary gear. The first external gear is coaxially fixedly mounted on the first crease roller and is provided with a fixing member that may be fixed or not fixed to the first internal gear. The second gear is coaxially fixedly mounted on the second crease roller and meshes with the first external gear.

[0008] By adopting the above technical solution, during the production of tissue paper, the tissue paper is processed by passing between the breakpoint roller and the breakpoint auxiliary roller, and then processed by passing between the first crease roller and the second crease roller. When it is necessary to adjust the distance between the breakpoint cut marks and the creases after the tissue paper is produced to meet the needs of different usage scenarios, the fixing between the first external gear and the first internal gear is released. Then, the first external gear is rotated. During this process, the first internal gear remains stationary due to its meshing with the auxiliary gear. The first external gear drives the first crease roller and the second crease roller to adjust their rotation angle around their own axis through meshing with the second gear. This facilitates crease processing at different positions on the tissue paper, that is, it ultimately achieves production adjustment of different distances between the breakpoint cut marks and the creases, improving applicability. Moreover, during the adjustment process, it is only necessary to fix or not fix the first external gear and the first internal gear with the fixing component and then rotate the first external gear, making the operation convenient and fast.

[0009] Optionally, the first crease roller is fixedly mounted with a fixed sleeve by a key connection, and the first external gear is fixedly connected to the fixed sleeve by a fastening screw that passes through the fixed sleeve and engages with its own thread.

[0010] By adopting the above technical solution, the setting of the fixed sleeve facilitates the stable transmission of the torque of the first crease roller when it rotates to the first external gear, thereby helping to fully ensure the synchronous stability of the first external gear and the first crease roller when they rotate.

[0011] Optionally, the fixing component includes a fixing screw, and the first external gear has a fixing groove extending circumferentially around its own axis on the side facing the first internal gear. The fixing screw passes through the fixing groove and is threadedly engaged with the first internal gear.

[0012] By adopting the above technical solution, tightening the fixing screw so that the screw head of the fixing screw can be pressed against or not pressed against the first external gear, thus fixing or not fixing the first internal gear and the first external gear. The structure is simple and stable, and the operation is convenient. Furthermore, the sliding lock of the fixing screw in the fixing groove facilitates the stepless adjustment between the first internal gear and the first external gear.

[0013] By adopting the above technical solution, the drive assembly further includes a drive motor, a drive gear, a connecting gear, and a breakpoint gear. The drive motor is used to drive the drive gear to rotate. The drive gear meshes with the auxiliary gear. The breakpoint gear is coaxially fixedly installed on the breakpoint roller. The connecting gear is located between the auxiliary gear and the breakpoint gear and meshes with the auxiliary gear and the breakpoint gear.

[0014] By adopting the above technical solution, when the drive motor drives the drive gear to rotate, the auxiliary gear drives the breakpoint roller and the breakpoint auxiliary roller to rotate in the same direction through the meshing of the connecting gear and the breakpoint gear. The auxiliary gear also drives the first crease roller and the second crease roller to rotate synchronously through the meshing of the first internal gear and the first external gear and the second gear. All rollers can be driven to rotate synchronously by one motor, which is convenient and stable.

[0015] Optionally, the diameter of the first internal gear may be larger than the diameter of the first external gear.

[0016] By adopting the above technical solution, it is beneficial to increase the distance between the break point auxiliary roller and the first crease roller, so that the break point auxiliary roller and the first crease roller are less likely to interfere with each other when they rotate, which is conducive to further ensuring the overall operational stability of the device.

[0017] Optionally, both the first crease roller and the second crease roller have crease protrusions on their outer peripheral surfaces, and both have crease grooves on their outer peripheral surfaces, with the crease protrusions and grooves of the first crease roller and the second crease roller cooperating with each other.

[0018] By adopting the above technical solution, it is convenient and fast to directly and synchronously form creases on both sides of the paper towel during reciprocating folding through the cooperation of the first crease roller and the second crease roller, which is conducive to improving the production efficiency of paper towels.

[0019] Optionally, the drive assembly further includes an adjusting gear and an adjusting motor, the adjusting gear meshing with the second gear, and the adjusting motor driving the adjusting gear to rotate.

[0020] By adopting the above technical solution, the setting of adjusting the angle of the first external gear by adjusting the motor in conjunction with the adjusting gear and the second gear is conducive to further improving the work efficiency of the staff when adjusting the angle of the first external gear.

[0021] Optionally, the drive assembly further includes a first adjusting telescopic cylinder, a second adjusting telescopic cylinder, an adjusting rack, and an adjusting sleeve. The first adjusting telescopic cylinder is used to drive the adjusting sleeve to move toward or away from the first external gear. The adjusting rack slides and engages with the adjusting sleeve. When the adjusting sleeve moves to a position close to the first external gear, the adjusting rack meshes with the first external gear. The second adjusting telescopic cylinder is mounted on the adjusting sleeve and is used to drive the adjusting rack to move along the tangential direction of the first external gear.

[0022] By adopting the above technical solution, the adjustment of the rotation angle of the first external gear can be quickly achieved when the first internal gear and the first external gear are released from fixation by the first adjustment telescopic cylinder and the second adjustment telescopic cylinder driving the movement of the adjustment sleeve and the adjustment rack. This method is highly efficient, and the first adjustment telescopic cylinder driving the adjustment rack to move to a position away from the first external gear is less likely to cause interference to the first external gear, thus ensuring the overall operational stability of the device.

[0023] Secondly, this application provides a folded tissue paper, which adopts the following technical solution:

[0024] A folded tissue produced according to the above-mentioned online adjustment folding system includes multiple tissue units. Each tissue unit includes a first tissue part, a second tissue part, and a third tissue part. The first tissue part and the second tissue part are provided with a first crease, and the second tissue part and the third tissue part are provided with a second crease. The third tissue part and the first tissue part of two adjacent tissue units are connected by a break point.

[0025] By adopting the above technical solution, the continuous tissue units are connected end-to-end through the break point. When the tissue is pulled out, after the front tissue is completely pulled out, a section of the back tissue can be pulled out. At this time, the break point of the front tissue can be torn off. It is convenient to use. Furthermore, by adjusting the device, the distance between the break point and the first and second creases can be adjusted, thus making it easy to adapt to more different usage situations and highly applicable.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The first external gear, through meshing with the second gear, drives the first and second crease rollers to rotate around their own axes, thereby facilitating crease treatment at different positions on the tissue paper. In other words, it ultimately achieves production adjustment of different spacings between the tissue paper's cut marks and creases, improving its applicability.

[0028] 2. By tightening the fixing screw, the screw head can be tightened or loosened against the first external gear, thus fixing or loosening the first internal gear and the first external gear. The structure is simple and stable, and the operation is convenient.

[0029] 3. It facilitates the direct and synchronous reciprocating folding of both sides of the paper towel through the cooperation of the first and second folding rollers, which is convenient, fast, and conducive to improving the production efficiency of paper towels. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0041] This application discloses an online adjustment folding system. Example 1

[0042] Reference Figure 1 and Figure 2The online adjustment folding system includes a breakpoint assembly, a crease assembly, and a drive assembly mounted on the frame. The breakpoint assembly includes a breakpoint roller 1 and a breakpoint auxiliary roller 2, and the crease assembly includes a first crease roller 3 and a second crease roller 4. All four are rotatably mounted on the frame (not shown in the figure).

[0043] Reference Figure 2 and Figure 3 Specifically, the breakpoint roller 1 and the breakpoint auxiliary roller 2 are arranged side by side, as are the first crease roller 3 and the second crease roller 4. Both the breakpoint roller 1 and the breakpoint auxiliary roller 2 are located on top of the first crease roller 3 and the second crease roller 4, with the breakpoint roller 1 and the second crease roller 4 located on one side of the breakpoint auxiliary roller 2 and the first crease roller 3, respectively. During tissue feeding, the tissue first passes between the breakpoint roller 1 and the breakpoint auxiliary roller 2, then between the breakpoint auxiliary roller 2 and the first crease roller 3, and subsequently between the first crease roller 3 and the second crease roller 4.

[0044] Continue to refer to Figure 2 and Figure 3 The surface of the break roller 1 is fixedly provided with break blades 5. In this embodiment, five groups of break blades 5 are circumferentially distributed around the axis of the break roller 1, and each group of break blades 5 has multiple cutting breaks 51 evenly distributed along the axis of the break roller 1. The surface of the break auxiliary roller 2 is provided with break bottom blades 6 that correspond one-to-one with each group of break blades 5, so that when the tissue paper passes between the break roller 1 and the break auxiliary roller 2, the break blades 5 form the breaks in the tissue paper by cooperating with the break bottom blades 6.

[0045] Reference Figure 3 and Figure 4 In this embodiment, the outer peripheral surfaces (roller surfaces) of the first crease roller 3 and the second crease roller 4 are both provided with crease protrusions 7, and the outer peripheral surfaces (roller surfaces) of the first crease roller 3 and the second crease roller 4 are both provided with crease grooves 8. The crease protrusions 7 and crease grooves 8 of the first crease roller 3 and the second crease roller 4 cooperate to form creases when the tissue paper passes between the first crease roller 3 and the second crease roller 4 through the continuous cooperation of the crease protrusions 7 and crease grooves 8 on the first crease roller 3 and the second crease roller 4. In this embodiment, five sets of crease protrusions 7 and crease grooves 8 are evenly distributed around the axis of the first crease roller 3 and the second crease roller 4 and are staggered with each other.

[0046] Reference Figure 1 and Figure 2The drive assembly is used to drive the breakpoint roller 1, the breakpoint auxiliary roller 2, the first crease roller 3, and the second crease roller 4 to rotate. Specifically, the drive assembly includes a drive motor 9, a drive gear 10, a connecting gear 11, a breakpoint gear 12, an auxiliary gear 13, a first internal gear 14, a first external gear 15, and a second gear 16. Specifically, the drive motor 9 is mounted on the frame and is used to drive the drive gear 10 to rotate. The auxiliary gear 13 is coaxially fixedly mounted on the breakpoint auxiliary roller 2, and the drive gear 10 meshes with the auxiliary gear 13. The first internal gear 14 is coaxially rotatably mounted on the first crease roller 3 and meshes with the auxiliary gear 13, so that when the drive motor 9 drives the drive gear 10 to rotate, the auxiliary gear 13 drives the breakpoint auxiliary roller 2 and the first internal gear 14 to rotate synchronously.

[0047] Continue to refer to Figure 1 and Figure 2 The breakpoint gear 12 is coaxially fixedly connected to the breakpoint roller 1. A fixing block 17 is fixedly installed on the frame. The breakpoint roller 1 is rotatably connected to a connecting mounting rod 18. The connecting gear 11 is rotatably mounted on the connecting mounting rod 18. A pressure spring 19 is fixedly installed between the fixing block 17 and the connecting gear 11. Under the elastic force of the pressure spring 19, the connecting mounting rod 18 stably drives the connecting gear 11 to rotate between the auxiliary gear 13 and the breakpoint gear 12, so that the connecting gear 11 meshes with the auxiliary gear 13 and the breakpoint gear 12. Thus, when the auxiliary gear 13 drives the breakpoint auxiliary roller 2 to rotate, the breakpoint gear 12 drives the breakpoint roller 1 to rotate synchronously through meshing with the connecting gear 11.

[0048] Reference Figure 1 and Figure 4 The first external gear 15 is coaxially fixedly installed on the first crease roller 3. Specifically, the first crease roller 3 is fixedly installed with a fixed sleeve 22 by a key connection. The first external gear 15 is fixedly connected to the fixed sleeve 22 by a fastening screw 23 that passes through the fixed sleeve 22 and engages with its own thread. Multiple fastening screws 23 are evenly distributed around the axis of the fixed sleeve 22. In this embodiment, the fastening screws 23 are selected as internal hexagon screws and the number of fastening screws is selected as four.

[0049] Continue to refer to Figure 1 and Figure 4The first external gear 15 is provided with a fixing member that may or may not be fixed to the first internal gear 14. The second gear 16 is coaxially fixedly installed on the second crease roller 4 and meshes with the first external gear 15. When the first internal gear 14 and the first external gear 15 are fixed by the fixing member, the first internal gear 14 rotates, thereby driving the first external gear 15 and the first crease roller 3 to rotate synchronously, and simultaneously driving the second gear 16 and the second crease roller 4 to rotate synchronously. The diameter of the first internal gear 14 is larger than the diameter of the first external gear 15 to increase the distance between the breakpoint auxiliary roller 2 and the first crease roller 3, so that the breakpoint auxiliary roller 2 and the first crease roller 3 are less likely to interfere with each other when rotating, thereby ensuring the overall operational stability of the device.

[0050] Reference Figure 2 and Figure 4 Furthermore, the fixing component includes fixing screws 20. The first external gear 15 has a fixing groove 21 extending circumferentially around its own axis on the side facing the first internal gear 14. Multiple fixing grooves 21 are evenly distributed circumferentially around the axis of the first external gear 15. In this embodiment, the number of fixing grooves 21 is set to 5. The number of fixing screws 20 corresponds to the number of fixing grooves 21, with each fixing screw 20 passing through its respective fixing groove 21 and threadedly engaging with the first internal gear 14. By tightening the fixing screws 20, the screw heads can be tightened or loosened against the first external gear 15, thus fixing or loosening the relationship between the first internal gear 14 and the first external gear 15. The sliding of the fixing screws 20 within the fixing grooves 21 facilitates stepless adjustment between the first internal gear 14 and the first external gear 15.

[0051] The implementation principle of Example 1 is as follows: During the production of paper towels, the paper towels are processed by the breakpoint roller 1 and the breakpoint auxiliary roller 2, and then the paper towels are processed by the first crease roller 3 and the second crease roller 4. In order to meet the needs of different usage scenarios, when it is necessary to adjust the distance between the breakpoint knife marks and the creases after the paper towels are produced, the fixing bolt 20 is released from the fixing between the first external gear 15 and the first internal gear 14. Then, the first external gear 15 is rotated. During this process, the first internal gear 14 remains stationary due to its meshing with the auxiliary gear 13. The first external gear 15 rotates by meshing with the second gear 16, which drives the first crease roller 3 and the second crease roller 4 to adjust their rotation angles around their own axes synchronously. This facilitates the crease processing at different positions on the paper towels. That is, the production adjustment of different distances between the breakpoint knife marks and the creases of the paper towels is finally realized, improving the applicability. Example 2

[0052] Reference Figure 5 and Figure 6The difference between this embodiment and Embodiment 1 lies in the method of driving the first external gear 15 to rotate. In this embodiment, the driving assembly also includes an adjusting gear 24 and an adjusting motor 25. The adjusting gear 24 is rotatably mounted on the frame and meshes with the second gear 16. The adjusting gear 24 is mounted on the output end of the adjusting motor 25 so that the adjusting motor 25 drives the adjusting gear 24 to rotate. The setting of adjusting the angle of the first external gear 15 by the adjusting motor 25 in conjunction with the adjusting gear 24 and the second gear 16 facilitates further improvement in the work efficiency of the operator when adjusting the angle of the first external gear 15. In addition, in order to ensure the service life of the adjusting motor 25 and further improve the work efficiency of adjusting the angle of the first external gear 15, the installation of the first internal gear 14 can be eliminated in this Embodiment 2. The rotation of the auxiliary gear 13 and the second gear 16 can be realized by the two driving sources, the driving motor 9 and the adjusting motor 25, respectively, so that the rotation of the auxiliary gear 13 and the first external gear 15 do not interfere with each other.

[0053] The implementation principle of this embodiment is the same as that of Embodiment 1, so it will not be repeated here. Example 3

[0054] Reference Figure 7 The difference between this embodiment and embodiment 1 is that the way the first external gear 15 is driven to rotate is different. The drive assembly also includes a first adjusting telescopic cylinder 26, a second adjusting telescopic cylinder 27, an adjusting rack 28, and an adjusting sleeve 29. The first adjusting telescopic cylinder 26 is horizontally installed on the frame, and the adjusting sleeve 29 is vertically set and fixedly installed on one end of the piston rod of the first adjusting telescopic cylinder 26, so that the first adjusting telescopic cylinder 26 drives the adjusting sleeve 29 to move toward or away from the first external gear 15.

[0055] Continue to refer to Figure 7The adjusting rack 28 slides vertically and engages with the adjusting sleeve 29. When the adjusting sleeve 29 moves to a position close to the first external gear 15, the adjusting rack 28 meshes with the first external gear 15. The second adjusting telescopic cylinder 27 is vertically positioned and fixedly installed on the adjusting sleeve 29. The adjusting rack 28 is fixedly installed on one end of the piston rod of the second adjusting telescopic cylinder 27, so that the second adjusting telescopic cylinder 27 drives the adjusting rack 28 to move vertically. When the adjusting rack 28 moves to the position where it meshes with the first external gear 15, the second adjusting telescopic cylinder 27 drives the adjusting rack 28 to move vertically, that is, the adjusting rack 28 moves along the tangential direction of the first external gear 15, thus adjusting the rotation angle of the first external gear 15. This method is highly efficient and, when the first adjusting telescopic cylinder 26 drives the adjusting rack 28 to a position away from the first external gear 15, it is less likely to interfere with the first external gear 15, ensuring the overall operational stability of the device. The first adjusting telescopic cylinder 26 and the second adjusting telescopic cylinder 27 can be selected as pneumatic cylinders, electric cylinders or hydraulic cylinders, without specific limitations. In the embodiments of this application, both the first adjusting telescopic cylinder 26 and the second adjusting telescopic cylinder 27 are selected as hydraulic cylinders.

[0056] The implementation principle of this embodiment is the same as that of Embodiment 1, so it will not be repeated here.

[0057] This application also discloses a folding tissue paper. (See attached embodiments.) Figure 8 The folded tissue produced based on the above-mentioned online adjustment folding system includes multiple tissue units. Each tissue unit includes a first tissue part 30, a second tissue part 31, and a third tissue part 32. Specifically, the first tissue part 30 and the second tissue part 31 are provided with a first crease 33, and the first tissue part 30 and the second tissue part 31 are folded and connected through the first crease 33. A second crease 34 is provided between the second tissue part 31 and the third tissue part 32, and the second tissue part 31 and the third tissue part 32 are folded and connected through the second crease 34. The third tissue part 32 and the first tissue part 30 of two adjacent tissue units are connected by a breakpoint part 35. The breakpoint part 35 is formed by the processing of the drive breakpoint roller 1 and the breakpoint auxiliary roller 2, and its main function is to facilitate the user to tear the tissue when using it.

[0058] The implementation principle of the folded tissue paper in this application embodiment is as follows: During use, continuous tissue paper units are connected end-to-end by a breakpoint 35. When the tissue paper is pulled out, after the front tissue paper is completely pulled out, a section of the back tissue paper can be pulled out. At this time, the breakpoint connection of the front tissue paper can be torn off. It is convenient to use. Moreover, by adjusting the device, the distance between the breakpoint 35 and the first crease 33 and the second crease 34 can be adjusted, thereby making it easy to adapt to more different usage situations and making it highly applicable.

[0059] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
