[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1 , Figure 2 , Figure 4and Figure 6 The present invention provides a technical solution: a high-speed roll paper slitting machine, including a worktable 1, a support leg 11 fixedly connected to the bottom of the worktable 1, two symmetrically arranged first mounting seats 2 fixedly connected to one side of the worktable 1, a bearing 23 fixedly connected to the middle of each of the two first mounting seats 2, a receiving roller 22 fixedly connected between the two bearings 23, a roll paper body 21 wound and connected on the receiving roller 22, a receiving mechanism for receiving the cut roll paper body 21 provided on the other side of the worktable 1, a conveying mechanism for conveying the roll paper body 21 fixedly connected to the middle of the worktable 1, and a guide roller 51 and a cutting mechanism 52 rotatably arranged between the receiving roller 22 and the conveying mechanism.

[0035] An oil outlet pipe 46 is fixedly connected to the side of the first mounting base 2. One end of the oil outlet pipe 46 is connected to a groove in the first mounting base 2 that is adapted to the bearing 23. The other end of the oil outlet pipe 46 is fixedly connected to a piston cylinder 43 with built-in lubricating oil. A piston rod 42 is slidably connected inside the piston cylinder 43.

[0036] When cutting the paper roll body 21, the paper roll body 21 is installed on the receiving roller 22, and one end of the paper roll body 21 is pulled out, so that the pulled-out end of the paper roll body 21 is conveyed by the conveying mechanism. At this time, the receiving roller 22 rotates. The bearing 23 makes the rotation of the receiving roller 22 smoother. By controlling the piston rod 42 to slide into the piston cylinder 43, the lubricating oil in the piston cylinder 43 enters the groove in the first mounting seat 2 that matches the bearing 23 through the oil outlet pipe 46, so that the bearing 23 is lubricated by the lubricating oil, thereby ensuring the smooth rotation of the receiving roller 22, thus avoiding the paper roll body 21 from being pulled and torn due to jamming of the receiving roller 22. The receiving mechanism then receives the cut paper.

[0037] The conveying mechanism includes two first guide rollers 15 symmetrically rotatably connected inside the workbench 1. A first conveyor belt 16 is driven between the two first guide rollers 15. A pad 17 is fixedly connected to the middle of the workbench 1. The pad 17 is in contact with the inner surface of the first conveyor belt 16. A base 12 is fixedly connected to the side wall of the workbench 1. A first motor 13 is fixedly connected to the upper part of the base 12. A drive shaft 14 is fixedly connected to the output end of the first motor 13. The first guide roller 15 near the paper roll body 21 is fixedly connected to the drive shaft 14.

[0038] The first motor 13 is started, causing the drive shaft 14 to rotate. This causes the first guide roller 15, which is fixedly connected to the end of the drive shaft 14, to rotate. The rotating first guide roller 15 then drives another first guide roller 15 to rotate via the first conveyor belt 16. At this time, the first conveyor belt 16 is displaced, which in turn causes the paper roll body 21 located above the first conveyor belt 16 to receive the pulling force. The pad block 17 is set to support the first conveyor belt 16, thereby preventing the first conveyor belt 16 from collapsing and ensuring the friction between the first conveyor belt 16 and the paper roll body 21, so that the paper roll body 21 is transported stably.

[0039] The conveying mechanism also includes two symmetrically arranged second guide rollers 31, which are located above the first conveyor belt 16. Two sets of mounting blocks 34 are symmetrically fixedly connected to both sides of the workbench 1. A first hydraulic rod 33 is fixedly connected to the upper surface of each of the two sets of mounting blocks 34. A second mounting seat 3 is fixedly connected to the top of each of the two sets of first hydraulic rods 33. The two second guide rollers 31 are rotatably connected to the two sets of second mounting seats 3 respectively, and a second conveyor belt 32 is connected between the two second guide rollers 31.

[0040] By controlling the extension and retraction of the first hydraulic rod 33, the distance between the two second guide rollers 31 and the first conveyor belt 16 is changed, thereby adapting to the conveying of paper roll bodies 21 of different thicknesses. At the same time, when the two second guide rollers 31 approach the first conveyor belt 16, the pressure between the second conveyor belt 32, which is connected between the two second guide rollers 31 and the paper roll body 21 increases, further improving the stability of conveying the paper roll body 21.

[0041] The conveying mechanism also includes a drive wheel 36 and a driven wheel 35. The driven wheel 35 is fixedly connected to the end of the second guide roller 31 near the first motor 13. The driven wheel 35 is coaxially fixedly connected to the drive shaft 14. A belt 37 is connected between the drive wheel 36 and the driven wheel 35. A tensioning mechanism for tensioning the belt 37 is provided on the side wall of the worktable 1.

[0042] When the drive shaft 14 rotates, it can drive the driven wheel 35 to rotate synchronously through the drive wheel 36. At this time, the driven wheel 35 drives the second guide roller 31 fixedly connected to it to rotate. Then, the second guide roller 31 drives another second guide roller 31 to rotate through the second conveyor belt 32. At this time, the second conveyor belt 32 is displaced, so that the paper roll body 21 is conveyed. The tensioning mechanism ensures that the belt 37 can always remain taut when the driven wheel 35 is raised and lowered, so that the connection between the drive wheel 36 and the driven wheel 35 is not interrupted.

[0043] Reference Figure 1 , Figure 6 , Figure 7 and Figure 8Furthermore, the tensioning mechanism includes a guide wheel 38, a mounting plate 4 is fixedly connected to the side wall of the worktable 1, a piston cylinder 43 is fixedly connected to the upper surface of the mounting plate 4, a rectangular block 41 is fixedly connected to the top of the piston rod 42, the guide wheel 38 is rotatably connected to the side wall of the rectangular block 41, and the guide wheel 38 is in contact with the belt 37. A return spring 44 is sleeved on both the piston rod 42 and the piston cylinder 43, and the two ends of the return spring 44 are fixedly connected to the rectangular block 41 and the mounting plate 4 respectively.

[0044] The return spring 44 provides a downward pulling force to the rectangular block 41, which causes the guide wheel 38 rotatably connected to the rectangular block 41 to tend to move downward. At this time, the guide wheel 38 can pull the belt 37, thereby making the belt 37 taut. The piston cylinder 43 and piston rod 42 simultaneously support the rectangular block 41.

[0045] The bottom of the piston cylinder 43 is fixedly connected to an oil extraction pipe 45, and the bottom of the mounting plate 4 is fixedly connected to a box 431 for storing lubricating oil. The end of the oil extraction pipe 45 away from the piston cylinder 43 passes through the mounting plate 4 and extends to below the surface of the lubricating oil in the box 431. Both the oil extraction pipe 45 and the oil outlet pipe 46 are equipped with a one-way valve 47.

[0046] In the initial stage of conveying the paper roll body 21, it is necessary to adjust the distance between the second conveyor belt 32 and the first conveyor belt 16, thereby changing the state of the belt 37. As a result, the rectangular block 41 moves up and down under the action of the return spring 44, so that the piston rod 42 slides in the piston cylinder 43. This allows more lubricating oil in the piston cylinder 43 to flow out through the oil outlet pipe 46 to lubricate the bearing 23. After adjustment, the equipment is in operation. At this time, the belt 37 can vibrate slightly, thereby reducing the sliding amplitude of the piston rod 42 in the piston cylinder 43. At this time, the piston cylinder 43 draws a small amount of lubricating oil from the housing 431 through the oil extraction pipe 45 and discharges the lubricating oil through the oil outlet pipe 46 to lubricate the bearing 23, preventing excessive transfer of lubricating oil and overflow.

[0047] A diversion pipe 48 is fixedly connected to the first mounting base 2, which is away from the first motor 13. One end of the diversion pipe 48 is connected to the groove in the first mounting base 2 that is adapted to the bearing 23. The other end of the diversion pipe 48 passes through the side wall of the workbench 1 and is connected to the pad 17. At the same time, a microporous rubber block is provided at the end of the diversion pipe 48 near the pad 17. An oil outlet hole 49 is opened in the pad 17. The diversion pipe 48 is connected to the oil outlet hole 49, so that a small amount of lubricating oil can penetrate through the microporous rubber block to the surface of the pad 17, thereby lubricating the first conveyor belt 16 and the pad 17.

[0048] When excess lubricating oil is present in the groove of the first mounting base 2 that mates with the bearing 23, away from the first motor 13, it can flow through the diverter pipe 48 to the oil outlet 49. The lubricating oil then flows through the oil outlet 49 to the upper surface of the pad 17, thereby lubricating the first conveyor belt 16 and the pad 17 and ensuring the smooth operation of the conveying mechanism.

[0049] Please refer to Figure 4 The upper and lower bottom surfaces of the pad 17 are surrounded by guide groove frames 18 to seal the gap between the pad 17 and the first conveyor belt 16. It should be noted that the guide groove frames 18 are quadrilateral in shape, with all four sides of the upper and lower ends of the pad 17 enclosed by the guide groove frames 18. An oil groove is provided inside the guide groove frames 18. An oil-absorbing component 19 is detachably connected between the two guide groove frames 18 on the same side. The oil-absorbing component 19 includes an oil-absorbing housing 191 and oil-absorbing cotton disposed within the oil-absorbing housing 192. The inner cavity of the oil-absorbing housing 191 communicates with the oil groove, allowing the oil-absorbing cotton to absorb any lubricating oil overflowing between the pad 17 and the first conveyor belt 16, preventing the paper from getting dirty and ensuring both lubrication and good cleanliness. Furthermore, the oil-absorbing component 19 can be easily disassembled to replace the oil-absorbing cotton.

[0050] Please refer to Figure 5 and Figure 6 A fixing block 172 and a stop block 173 are fixedly installed on the pad block 17. A sliding block 171 is slidably connected to the pad block 17. The oil suction housing 191 is positioned between the two fixing blocks 172. A first locking hole 1911 is provided on the oil suction housing 191. A locking plate 181 is provided on the surface of the guide groove frame 18. A second locking hole is provided on the locking plate 181. A first locking block 1711 for engaging with the first locking hole 1911 and a second locking block 1712 for engaging with the second locking hole are provided on the sliding block 171. The first locking block 1711 penetrates the fixing block 172 and engages with the first locking hole 1911.

[0051] The stop block 173 is located on the sliding track of the sliding block 171. An elastic element 174 is compressed between the stop block 173 and the sliding block 171. The elastic element 174 can squeeze the first locking block 1711 to engage in the first locking hole 1911, and at the same time squeeze the second locking block 1712 to engage in the second locking hole. While securing the oil suction housing 191, it can connect the guide groove frame 18, the oil suction housing 191 and the pad block 17 into a tighter and more stable overall structure.

[0052] Reference Figure 1 , Figure 2 ,and Figure 10Furthermore, two third mounting seats 5 are bolted to the two sides of the workbench 1 near the paper roll body 21. The guide roller 51 is rotatably connected between the two third mounting seats 5. The cutting mechanism 52 is connected to the third mounting seats 5 and is located on one side of the guide roller 51. Figure 10 The cutting mechanism 52 is shown in a simplified manner. The cutting mechanism for the roll paper can be a pneumatic slitting knife as used in the prior art, which will not be described in detail here.

[0053] Reference Figure 1 and Figure 3 Furthermore, the receiving mechanism includes a mounting frame 6, which is fixedly connected to the end of the workbench 1. Four fourth hydraulic rods 63 arranged in a rectangular array are fixedly connected to the bottom of the mounting frame 6. A receiving plate 62 is fixedly connected to the top of the four fourth hydraulic rods 63. A sensor 64 for monitoring the paper stacking height to control the retraction of the fourth hydraulic rods 63 can be fixedly connected to the inner wall of the mounting frame 6. The sensor 64 can be an infrared through-beam sensor. A baffle 61 is rotatably connected to the side of the mounting frame 6 away from the workbench 1.

[0054] When receiving paper, the baffle 61 is closed. After being conveyed by the conveying mechanism, the paper moves to the upper part of the receiving plate 62 under the action of inertia. The baffle 61 blocks the paper to ensure that the paper can be neatly stacked on the receiving plate 62. The sensor 64 monitors the stacking height of the paper in real time and controls the fourth hydraulic rod 63 to ensure that when the paper is stacked to a certain height, the fourth hydraulic rod 63 retracts, causing the receiving plate 62 to descend and continue to receive the paper.

[0055] Working principle: When the high-speed roll paper slitting machine slits the roll paper body 21, the roll paper body 21 is mounted on the receiving roller 22, and one end of the roll paper body 21 is pulled out, so that the pulled end of the roll paper body 21 is conveyed by the conveying mechanism. At this time, the receiving roller 22 rotates. The bearing 23 makes the rotation of the receiving roller 22 smoother. By controlling the piston rod 42 to slide into the piston cylinder 43, the lubricating oil in the piston cylinder 43 enters the groove in the first mounting seat 2 that matches the bearing 23 through the oil outlet pipe 46, so that the bearing 23 is lubricated by the lubricating oil, thereby ensuring the smooth rotation of the receiving roller 22, thus avoiding the receiving roller 22 from jamming, which would cause the roll paper body 21 to be pulled and result in poor paper cutting effect. The receiving mechanism then receives the slit paper.

[0056] The first motor 13 is started, causing the drive shaft 14 to rotate. This, in turn, causes the first guide roller 15, which is fixedly connected to the end of the drive shaft 14, to rotate. The rotating first guide roller 15 then drives another first guide roller 15 to rotate via the first conveyor belt 16. At this time, the first conveyor belt 16 is displaced, which in turn causes the paper roll body 21 located above the first conveyor belt 16 to receive pulling power. The pad block 17 provides support for the first conveyor belt 16, thereby preventing the first conveyor belt 16 from collapsing and ensuring the friction between the first conveyor belt 16 and the paper roll body 21. By controlling the extension and retraction of the first hydraulic rod 33, the distance between the two second guide rollers 31 and the first conveyor belt 16 is changed, which can control the pressing force between the second conveyor belt 32 and the first conveyor belt 16 on the paper roll body 21. This allows for the conveying of paper roll bodies 21 of different thicknesses. At the same time, when the two second guide rollers 31 are close to the first conveyor belt 16, the pressure between the second conveyor belt 32, which is connected between the two second guide rollers 31 and the paper roll body 21, increases, further improving the stability of the conveying of the paper roll body 21.

[0057] When the drive shaft 14 rotates, it can drive the driven wheel 35 to rotate synchronously through the drive wheel 36. At this time, the driven wheel 35 drives the second guide roller 31 fixedly connected to it to rotate. Then, the second guide roller 31 drives another second guide roller 31 to rotate through the second conveyor belt 32. At this time, the second conveyor belt 32 is displaced, so that the paper roll body 21 is conveyed. The tensioning mechanism ensures that the belt 37 can always remain taut when the driven wheel 35 is raised and lowered, so that the transmission between the drive wheel 36 and the driven wheel 35 is stable.

[0058] The return spring 44 provides a downward pulling force to the rectangular block 41, which causes the guide wheel 38 rotatably connected to the rectangular block 41 to tend to move downward. At this time, the guide wheel 38 can pull the belt 37, thereby making the belt 37 taut. The piston cylinder 43 and piston rod 42 simultaneously support the rectangular block 41. In the initial stage of conveying the paper roll body 21, it is necessary to adjust the distance between the second conveyor belt 32 and the first conveyor belt 16, thereby changing the state of the belt 37. As a result, the rectangular block 41 moves up and down under the action of the return spring 44, causing the piston rod 42 to slide inside the piston cylinder 43, thereby allowing more lubricating oil inside the piston cylinder 43 to flow out through the oil outlet pipe 46 to lubricate the bearing 23.

[0059] After adjustment, the equipment is in operation. At this time, the belt 37 can vibrate slightly, which reduces the sliding amplitude of the piston rod 42 in the piston cylinder 43. At this time, the piston cylinder 43 draws a small amount of lubricating oil from the housing 431 through the oil extraction pipe 45 and discharges the lubricating oil through the oil outlet pipe 46 to lubricate the bearing 23, preventing excessive transfer of lubricating oil and overflow.

[0060] When the lubricating oil in the groove of the first mounting base 2, which is far from the first motor 13 and mates with the bearing 23, is excessive, it can flow through the diversion pipe 48 to the oil outlet 49. Then, the lubricating oil flows through the oil outlet 49 to the upper surface of the pad 17, so that the first conveyor belt 16 and the pad 17 are lubricated, ensuring the smooth operation of the conveying mechanism. At the same time, the guide frame 18 and the oil suction component 19 ensure the cleanliness of the outside of the first conveyor belt 16.

[0061] When receiving paper, the baffle 61 is closed. After being conveyed by the conveying mechanism, the paper moves to the upper part of the receiving plate 62 under the action of inertia. The baffle 61 blocks the paper, ensuring that the paper can be neatly stacked on the receiving plate 62. The sensor 64 monitors the stacking height of the paper in real time and controls the fourth hydraulic rod 63 to ensure that when the paper is stacked to a certain height, the fourth hydraulic rod 63 retracts, causing the receiving plate 62 to descend and continue to receive the paper, so that the height of the paper received is relatively fixed and the receiving is more stable.

[0062] 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.
