Description

Technical Field

[0001] This invention relates to the field of paper product manufacturing technology, and in particular to an anti-rolling conveyor and paper cutting device. Background Technology

[0002] In the production of some paper products, a large roll of raw paper is unwound from a roller. During unwinding, the paper is evenly cut along its width. Subsequently, there are many rewinding stations that correspond one-to-one with the cutting stations, where the unwound paper is rewound. After a certain amount is rewound, it is moved to the packaging station at the end, thus producing rolls of paper that are compliant in size and ready for direct use by consumers.

[0003] However, paper transport via rollers differs from the transport of other materials, such as tensile films. Film transport allows the rear traction roller to passively unwind the front unwind roller, ensuring that the amount of paper used corresponds to the amount unwound at the front. Paper cutting equipment cannot operate this way, as pulling the paper in this manner would cause it to break. Therefore, in paper cutting equipment, both the traction roller and the unwind roller are powered rollers. To maintain proper tension of the paper from the unwind roller to the traction roller, parameters need to be set for both motors, allowing them to operate in coordination. However, because the traction roller and the unwind roller are not mechanically interlocked, they cannot be dynamically adjusted in real time according to actual conditions. For example, if the paper being processed has different thicknesses, there is a possibility that during the unwinding process, the paper may not be tensioned properly from the unwind roller to the traction roller, which can easily lead to paper rolls. Summary of the Invention

[0004] The technical problem to be solved by the present invention is how to prevent paper from rolling during the paper conveying process of paper cutting equipment, and provides an anti-rolling paper conveying and cutting equipment.

[0005] The technical solution of the present invention is an anti-winding conveying and cutting paper device, comprising a conveying device, a slitting device, a winding device, and a cutting device arranged sequentially. The conveying device includes a downward pressing electric cylinder disposed above the unwinding roller. A pressing plate is provided at the end of the downward pressing electric cylinder. The downward pressing electric cylinder drives the pressing plate downward according to the thickness change of the paper roll on the unwinding roller to adhere to the surface of the paper roll. A downwardly extending pressure roller is provided below the pressing plate. A transverse moving shaft cylinder is sleeved on the unwinding roller. An inclined groove is formed on the side wall of the transverse moving shaft cylinder to cooperate with the pressure roller. The pressure roller presses down on the inclined groove to drive the transverse moving shaft cylinder to move laterally outward along the axial direction of the unwinding roller. The outer end of the transverse moving shaft cylinder is provided with an inner flared opening. The outer end of the unwinding roller protrudes from the outer end of the transverse moving shaft cylinder and is provided with a disc. A plurality of moving grooves are formed on the disc along its radial direction. A sliding member is slidably connected in each of the moving grooves. The sliding member is provided with a matching part on the side facing the transverse moving shaft cylinder. The sliding member has an arc plate on the side facing away from the transverse shaft cylinder, with a gap between each arc plate. The disc also has an outer ring on the side facing the transverse shaft cylinder. A tension spring connects each sliding member and the outer ring. A relay turntable is provided on the side plate through which the unwinding roller passes. The wheel tracks formed by each arc plate and the relay turntable are connected by a first conveyor belt. The side plate also has a rotating wheel that drives the traction roller to rotate synchronously. The rotating wheel and the relay turntable are connected by a second conveyor belt. The side plate also has an upper lifting electric cylinder. The end of the upper lifting electric cylinder has a tensioning wheel that cooperates with the first conveyor belt. A pressure sensor for feedback of the pressure of the first conveyor belt is provided between the upper lifting electric cylinder and the tensioning wheel. The upper lifting electric cylinder drives the tensioning wheel upward to fit the first conveyor belt according to the pressure value feedback from the pressure sensor.

[0006] In one embodiment, the unwinding roller is provided with a paper tube, and the paper roll is disposed on the paper tube.

[0007] In one embodiment, the pressing plate is arc-shaped, and the bottom surface of the pressing plate is smooth.

[0008] In one embodiment, the side plate is also provided with a lower pressure seat, and the lower pressure electric cylinder is fixed on the lower pressure seat.

[0009] In one embodiment, the side plate is also provided with an upper top seat, and the upper top electric cylinder is fixed on the upper top seat.

[0010] In one implementation, the upper electric cylinder operates within a range of a first reference value and a second reference value. The range of the first reference value and the second reference value includes a first pressure value and a second pressure value. When the pressure value fed back by the pressure sensor is greater than the first pressure value but less than the first reference value, the upper electric cylinder retracts downward. When the pressure value fed back by the pressure sensor is less than the second pressure value but greater than the second reference value, the upper electric cylinder extends upward, so that the pressure fed back by the pressure sensor is always within the range of the first pressure value and the second pressure value.

[0011] In one embodiment, at least four of the sliding grooves, sliding members, and arc plates are provided, and each of the sliding grooves, sliding members, and arc plates is evenly distributed along the circumferential direction.

[0012] In one embodiment, the upper electric cylinder is provided with a U-shaped wheel frame at its end, the pressure sensor is located between the upper electric cylinder and the wheel frame, the wheel frame is provided with a wheel axle at its end, and the tensioning wheel is located on the wheel axle.

[0013] In one embodiment, the tensioning wheel has a belt groove on its surface, and the first transmission belt is embedded in the belt groove.

[0014] In one embodiment, a first lower guide roller and a second lower guide roller are respectively located below the unwinding roller and the traction roller between the two side plates. A double-station bottom roller and a deflecting roller are also provided between the two side plates. The double-station bottom roller is located below the first lower guide roller and the second lower guide roller, and the deflecting roller is located above the traction roller. The paper pulled out of the paper roll is guided sequentially through the first lower guide roller, the double-station bottom roller, the second lower guide roller, and the deflecting roller to the traction roller. A transverse guide screw is provided between the double-station bottom roller and the first lower guide roller and the second lower guide roller. A slide is provided on the transverse guide screw, and a three-pronged plate is provided between the two slides. The three-pronged plate is provided with three electrostatic generating rods that extend into the space between the double-station bottom roller and the first lower guide roller, inside the double-station bottom roller, and between the double-station bottom roller and the second lower guide roller, respectively. The transverse guide screw is connected to the relay turntable through a reciprocating mechanism.

[0015] The advantages of this invention compared to existing technologies are that the paper cutting equipment is adjusted in real time during operation, specifically the speed ratio between the unwinding roller and the traction roller. As the thickness of the paper roll on the unwinding roller decreases, the pressure plate descends under the drive of the lower pressure cylinder, lightly touching the surface of the paper roll, thus avoiding interference with normal paper output. The pressure roller, along with the downward pressure of the pressure plate, presses against the inclined groove, causing the transverse shaft to move laterally. This transverse movement of the transverse shaft causes the surrounding sliding parts to converge, and on the other side of the disc, the surrounding arc plates converge, reducing the wheel tracks formed by each arc plate. Simultaneously, the upper electric cylinder controls the tensioning roller in real time to keep it close to the first conveyor belt. A pressure sensor located between the upper electric cylinder and the tensioning roller detects any loosening of the first conveyor belt, causing the upper electric cylinder to push upwards to maintain tension on the first conveyor belt. Therefore, changes occurring in real time at the unwinding roller are ultimately transmitted to the guide traction roller, and the two work closely together in real-time dynamic adjustment, avoiding inappropriate speed ratios that could cause paper winding problems.

[0023] The above and other embodiments and advantages 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.

[0024] In one implementation, such as Figure 1-5 As shown.

[0025] The anti-winding conveying and cutting paper device provided in this embodiment includes a conveying device 1, a slitting device 2, a winding device 3, and a cutting device 4 arranged sequentially. The conveying device 1 includes a downward pressing cylinder 6 located above the unwinding roller 5. A pressure plate 7 is provided at the end of the downward pressing cylinder 6. The downward pressing cylinder 6 drives the pressure plate 7 downward according to the thickness change of the paper roll on the unwinding roller 5 to adhere to the surface of the paper roll. A downwardly extending pressure roller 8 is provided below the pressure plate 7. A transverse shaft cylinder 9 is sleeved on the unwinding roller 5. The transverse shaft cylinder 9 has a side... The wall is provided with a groove 10 that matches the pressure roller 8. The pressure roller 8 presses down on the groove 10, which drives the transverse shaft cylinder 9 to move outward along the axial direction of the unwinding roller 5. The outer end of the transverse shaft cylinder 9 is provided with an inner flared opening 11. The outer end of the unwinding roller 5 protrudes from the outer end of the transverse shaft cylinder 9 and is provided with a disc 12. The disc 12 is provided with a plurality of shifting grooves 13 along its radial direction. Each shifting groove 13 is slidably connected to a sliding member 14. The side of the sliding member 14 facing the transverse shaft cylinder 9 is provided with a slanted rod 15 that matches the inner flared opening 11. A circular arc plate 16 is provided on the side of the sliding member 14 facing away from the transverse shaft cylinder 9, and a gap 17 is provided between each circular arc plate 16. An outer ring 18 is also provided on the side of the disc 12 facing the transverse shaft cylinder 9. A tension spring 19 is connected between each sliding member 14 and the outer ring 18. A relay turntable 21 is provided on the side plate 20 through which the unwinding roller 5 passes. The wheel tracks formed by each circular arc plate 16 and the relay turntable 21 are connected by a first conveyor belt 22. The side plate 20 is also provided with a rotating mechanism that drives the traction roller 23 to rotate synchronously. The wheel 24 and the relay turntable 21 are connected by a second conveyor belt 25. The side plate 20 is also provided with an upper lifting cylinder 26. The end of the upper lifting cylinder 26 is provided with a tensioning wheel 27 that cooperates with the first conveyor belt 22. A pressure sensor 28 for feedback of the pressure of the first conveyor belt 22 is also provided between the upper lifting cylinder 26 and the tensioning wheel 27. The upper lifting cylinder 26 drives the tensioning wheel 27 upward to fit the first conveyor belt 22 according to the pressure value feedback from the pressure sensor 28.

[0026] In this embodiment, by adopting the above-described technical solution, the paper cutting equipment is adjusted in real time during operation, specifically the speed ratio between the unwinding roller 5 and the traction roller 23. This is because as the thickness of the paper roll on the unwinding roller 5 decreases, the total length of paper corresponding to one rotation of the unwinding roller 5 also decreases. It is difficult to dynamically adjust the parameters of the two motors according to actual conditions, especially considering the issue of inconsistent paper thickness. However, in this embodiment, as the thickness of the paper roll on the unwinding roller 5 decreases, the pressure plate 7 descends under the drive of the lower pressure cylinder 6, lightly contacting the surface of the paper roll, thereby avoiding interference with normal paper output.

[0027] like Figure 4As shown, the pressure roller 8 presses down on the inclined groove 10 as the pressure plate 7 presses down, and the transverse shaft cylinder 9, which is fitted on the unwind roller 5, can move laterally relative to it. Therefore, as the pressure roller 8 presses down, it can drive the transverse shaft cylinder 9 outward. In the figure, the position of the disc 12 is considered the outer side. The unwind roller 5 is connected to the disc 12 and drives it to rotate synchronously. The disc 12 has several sliding parts 14 arranged in a circular array. Four are shown in the figure, all along the radial direction of the disc 12. In the initial state, under the action of the tension spring 19, the inclined rod 15 connected to the sliding parts 14 is pressed tightly against the inner wall of the inner flared opening 11 of the transverse shaft cylinder 9. Therefore, as the transverse shaft cylinder 9 moves laterally, the sliding parts 14 around it can be brought together. Looking at the other side of the disc 12, that is, the arc plates 16 around it are brought together, thus reducing the wheel tracks formed by each arc plate 16. Of course, this process is slow. There is a small variable every time the unwinding roller 5 rotates, so the first conveyor belt 22 will not slip off the wheel track and the relay turntable 21.

[0028] However, in real-time coordination, the upper electric cylinder 26 controls the tensioning wheel 27 to keep it pressed tightly against the first conveyor belt 22. A pressure sensor 28, positioned between the upper electric cylinder 26 and the tensioning wheel 27, can detect any loosening of the first conveyor belt 22, causing the upper electric cylinder 26 to push upwards to maintain tension on the first conveyor belt 22. Specifically, the upper electric cylinder 26 operates within a set range of a first reference value and a second reference value. This range includes a first pressure value and a second pressure value. When the pressure value fed back by the pressure sensor 28 is greater than the first pressure value but less than the first reference value, the upper electric cylinder 26 retracts downwards. When the pressure value fed back by the pressure sensor 28 is less than the second pressure value but greater than the second reference value, the upper electric cylinder 26 extends upwards, ensuring that the pressure fed back by the pressure sensor 28 remains within the range of the first and second pressure values. Therefore, by adopting the above technical solution, changes generated in real-time at the unwinding roller 5 are ultimately transmitted to the guide roller 23. The two work closely together in real-time dynamic adjustment, avoiding inappropriate speed ratios that could cause paper winding problems.

[0029] In one implementation, such as Figure 2 As shown.

[0030] The anti-winding conveying and cutting paper device provided in this embodiment has a paper tube 29 on its unwinding roller 5, and the paper roll is placed on the paper tube 29.

[0031] In this embodiment, a paper tube 29 is provided on the unwinding roller 5, and the paper roll is placed on the paper tube 29. The paper tube 29 is a carrier that provides a fixation for the paper roll.

[0032] In one implementation, such as Figure 2 As shown.

[0033] The anti-rolling conveyor paper cutting device provided in this embodiment has an arc-shaped pressure plate 7, and the bottom surface of the pressure plate 7 is a smooth surface.

[0034] In this embodiment, by using an arc-shaped pressure plate 7, it can roughly fit the surface of the paper roll. The arc shape of the pressure plate 7 is an enlarged bracket, and the bottom surface of the pressure plate 7 is a smooth surface with low friction, which can avoid affecting normal paper output.

[0035] In one implementation, such as Figure 2 As shown.

[0036] The anti-rolling conveying and cutting paper device provided in this embodiment also has a lower pressure seat 30 on its side plate 20, and the lower pressure electric cylinder 6 is fixed on the lower pressure seat 30.

[0037] In this embodiment, a pressure seat 30 is provided on the side plate 20 to fix and install the pressure cylinder 6. The pressure seat 30 is installed on the top of the side plate 20, and the pressure cylinder 6 moves downward.

[0038] In one implementation, such as Figure 5 As shown.

[0039] The anti-rolling conveyor paper cutting device provided in this embodiment also has an upper top seat 31 on its side plate 20, and an upper top electric cylinder 26 is fixed on the upper top seat 31.

[0040] In this embodiment, the upper electric cylinder 26 is fixedly installed by the upper top seat 31 provided on the outer side of the side plate 20. Specifically, the upper electric cylinder 26 is installed inside the circle formed by the first conveyor belt 22. Of course, in other embodiments, the upper electric cylinder 26 can also be installed outside the circle formed by the first conveyor belt 22.

[0041] In one implementation, such as Figure 2 , Figure 4 As shown.

[0042] The anti-rolling conveying and cutting paper device provided in this embodiment has at least four shifting grooves 13, sliding parts 14, and arc plates 16, and each shifting groove 13, sliding part 14, and arc plate 16 is evenly distributed along the circumferential direction.

[0043] In this embodiment, the number of sliding grooves 13, sliding members 14, and arc plates 16 are all set to 4.

[0044] In one implementation, such as Figure 5 As shown.

[0045] The anti-rolling conveying and cutting paper device provided in this embodiment has a U-shaped wheel frame 32 at the end of the upper electric cylinder 26, a pressure sensor 28 between the upper electric cylinder 26 and the wheel frame 32, a wheel axle 33 at the end of the wheel frame 32, and a tensioning wheel 27 on the wheel axle 33.

[0046] In this embodiment, a structure for the tensioning wheel 27 is provided. The tensioning wheel 27 is mounted on a U-shaped wheel frame 32. A pressure sensor 28 is provided between the wheel frame 32 and the end of the upper electric cylinder 26. The pressure sensor 28 detects pressure and controls the movement of the upper electric cylinder 26. Specifically, the upper electric cylinder operates within a range of a first reference value and a second reference value. This range includes a first pressure value and a second pressure value. When the pressure value fed back by the pressure sensor is greater than the first pressure value but less than the first reference value, the upper electric cylinder retracts downwards. When the pressure value fed back by the pressure sensor is less than the second pressure value but greater than the second reference value, the upper electric cylinder extends upwards, ensuring that the pressure fed back by the pressure sensor remains within the range of the first and second pressure values. In a preferred embodiment, the tensioning wheel 27 of the anti-winding conveyor paper cutter has a belt groove 34 on its surface, and a first conveyor belt 22 is embedded in the belt groove 34. This prevents the first conveyor belt 22 from detaching from the tensioning wheel 27.

[0047] In one implementation, such as Figure 6 As shown.

[0048] The anti-winding conveying and cutting paper device provided in this embodiment has a first lower guide roller 35 and a second lower guide roller 36 located below the unwinding roller 5 and the traction roller 23, respectively, between its two side plates 20. A double-station bottom roller 37 and a deflecting roller 38 are also provided between the two side plates 20. The double-station bottom roller 37 is located below the first lower guide roller 35 and the second lower guide roller 36, and the deflecting roller 38 is located above the traction roller 23. The paper pulled out of the paper roll passes sequentially through the first lower guide roller 35, the double-station bottom roller 37, the second lower guide roller 36, and the deflecting roller 38. The guide roller 38 is guided to the traction roller 23. A transverse guide screw 39 is provided between the double-station bottom roller 37 and the first lower guide roller 35 and the second lower guide roller 36. A slide 40 is provided on the transverse guide screw 39. A three-pronged plate 41 is provided between the two slides 40. Three electrostatic generating rods 42 are provided on the three-pronged plate 41, which respectively extend between the double-station bottom roller 37 and the first lower guide roller 35, inside the double-station bottom roller 37, and between the double-station bottom roller 37 and the second lower guide roller 36. The transverse guide screw 39 is connected to the relay turntable 21 through a reciprocating mechanism.

[0049] In this embodiment, the unwinding roller 5, the first lower guide roller 35, the double-station bottom roller 37, the second lower guide roller 36, the deflecting roller 38, and the traction roller 23 arranged in the above scheme can guide the paper conveyor line pulled from the paper roll in a U-shape, first downward and then upward. The deflecting roller 38 and the traction roller 23 locally have a deflecting function, preventing paper loosening at the traction roller 23. Overall, the U-shaped conveyor line increases the effective area of ​​one side of the paper exposed within the U-shaped space, allowing the electrostatic generator 42 sufficient space for one side of the paper to become electrostatically charged. It should be noted that the relay turntable 21 is connected to the reciprocating mechanism. As the relay turntable 21 rotates continuously, this reciprocating mechanism drives the transverse lead screw 39 to periodically and regularly rotate in both directions, thereby driving the slide 40, the three-pronged plate 41, and the three electrostatic generators 42 on it to move back and forth transversely. Three electrostatic generators 42 point in different directions, one towards the downward section, one towards the horizontal section, and one towards the upward section of the conveyor line, respectively, to ensure that one side of the paper is charged with static electricity. Once charged, the paper adheres tightly to each roller, and even if the paper is loose in this section of the conveyor line, the strong attraction of the static electricity will absorb it, preventing paper rolls during transport. Unlike the first implementation method, which uses real-time adjustment of the rotation speed to prevent paper rolls due to insufficient tension, this implementation method further improves upon this, ensuring that even if the paper is not fully tensioned, it still provides some unwinding and conveying function. Furthermore, the statically charged paper is more conducive to winding after slitting; after winding and cutting, it can be destaticated. Overall, by adding two processes, the failure rate of the production line can be reduced, resulting in a certain degree of efficiency improvement.

[0050] The specific embodiments described above further illustrate the inventive purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. In particular, it should be noted that any modifications, equivalent substitutions, or improvements made by those skilled in the art within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
