Description

Technical Field

[0001] This invention relates to the field of paper trimming, and more particularly to a trimming device for papermaking. Background Technology

[0002] Papermaking is an important invention of the ancient Chinese working people. It has two forms: machine-made and handmade. Machine-made papermaking is a continuous process. Pulp suitable for paper quality is diluted with water to a certain concentration and initially dewatered on the wire section of the papermaking machine to form a wet sheet. It is then pressed to dewater and dried into paper. After the paper is produced, it needs to be wound up. Before winding up, the two sides of the paper need to be cut to achieve the required frame size and ensure the smoothness of the paper edges.

[0003] In existing technology, papermaking machinery uses cutting equipment to cut paper. The paper strips produced after cutting the paper will accumulate around the device, which will affect the subsequent cutting of the paper edges, thus causing paper waste. Summary of the Invention

[0004] In order to avoid wasting paper, this application provides a cutting device for papermaking.

[0005] This application provides a paper-cutting device for papermaking, which adopts the following technical solution: A paper-cutting device includes a worktable, a tensioning and conveying mechanism, a cutting mechanism for cutting paper, and a chip removal mechanism on one side of the worktable that works with the cutting mechanism to discharge the cut paper waste strips from the worktable. The chip removal mechanism includes a blower and a chip removal duct. The blower is located on one side of the worktable, and the air inlet of the chip removal duct is connected to the air outlet of the blower. A chip inlet is provided on the side wall of the chip removal duct for discharging the cut paper waste strips.

[0006] By adopting the above technical solution, the paper is transported by the tensioning conveyor mechanism and cut by the cutting mechanism. The cut paper waste strips enter the chip discharge duct through the chip inlet. The blower blows air into the chip discharge duct, and the gas carries the paper waste strips out of the chip discharge duct and accumulates together, avoiding the accumulation of paper waste around the device and avoiding affecting the subsequent cutting of the paper edges, thereby achieving the effect of avoiding paper waste.

[0007] Optionally, ventilation holes are evenly spaced along the length of the chip removal duct on the side wall, and each ventilation hole is located on the same side of the chip inlet.

[0008] By adopting the above technical solution, the cut paper waste strips enter the chip discharge duct through the chip inlet. The blower blows air into the chip discharge duct, causing the gas flow rate inside the chip discharge duct to be faster than the gas flow rate outside the chip discharge duct. The gas outside the chip discharge duct enters the chip discharge duct through the vent, thereby preventing the paper waste strips entering the chip discharge duct from being adsorbed on the side wall of the chip discharge duct where the vent is opened and difficult to discharge from the chip discharge duct.

[0009] Optionally, the tensioning conveying mechanism includes conveying rollers and tensioning rollers. Multiple conveying rollers are provided, each rotatably mounted on the worktable and parallel to the same vertical plane. A V-block is provided on the worktable, rotatably connected to it.

A second fixing block is fixedly mounted on the V-block. One end of the tension spring is connected to the first fixing block, and the other end is connected to the second fixing block. A hook is also provided on the V-block, rotatably connected to the second fixing block. A fixed shaft is fixedly mounted on the worktable, cooperating with the hook to relax the tensioning roller.

[0010] By adopting the above technical solution, when the tensioning conveyor is not working, the hook is hooked onto the fixed shaft, and the tensioning roller is in a relaxed state. When the tensioning conveyor is running, the hook is disengaged from the fixed shaft, and the tensioning roller automatically tensions the conveyed items under the tension of the tension spring.

[0011] Optionally, two sets of the adjusting components are provided on the worktable, and the two V-blocks are rotatably connected to the two ends of the tension roller, respectively. The first fixing block, the second fixing block, the tension spring, and the hook are each provided with two corresponding adjusting components.

[0012] By adopting the above technical solution, two sets of adjustment components are set up symmetrically on both sides of the worktable and connected to the two ends of the tension roller, respectively, to ensure the stability of the tension roller adjustment work.

[0013] Optionally, the tensioning conveying mechanism includes a conveying roller and a tensioning roller. Multiple conveying rollers are provided, each rotatably mounted on the worktable and parallel to the same vertical plane. A mounting block is provided on the worktable, and the tensioning roller is rotatably connected to the mounting block. An adjusting component for adjusting the tensioning roller is provided on the worktable. The adjusting component includes an adjustable bolt and a fixing block. The fixing block has multiple mounting holes for fixing it to the worktable. A guide rail is provided on the fixing block, and the mounting block slides along the guide rail to connect with the fixing block. One end of the adjustable bolt extends into the guide rail and is rotatably connected to the mounting block. The sidewall of the adjustable bolt is threadedly connected to the fixing block.

[0014] By adopting the above technical solution, the fixing block is fixed on the worktable through the mounting hole. The fixing block is equipped with a guide rail, which plays a guiding role in the lateral movement of the tensioning roller. The position of the tensioning roller can be changed by adjusting the adjustable bolt, thereby achieving tensioning of the conveyed paper.

[0015] Optionally, two mounting blocks are provided on the worktable, and the two mounting blocks are symmetrically arranged on the worktable. The two mounting blocks are rotatably connected to the two ends of the tension roller, and two sets of adjusting members are provided on the worktable corresponding to the two mounting blocks.

[0016] By adopting the above technical solution, two sets of adjustment components are set up symmetrically on both sides of the worktable and connected to the two ends of the tension roller, respectively, to ensure the stability of the tension roller adjustment work.

[0017] Optionally, the tensioning conveying mechanism includes a conveying roller and a tensioning roller. Multiple conveying rollers are provided, each of which is rotatably mounted on the worktable and is parallel to the same vertical plane. The worktable is provided with an adjusting component for adjusting the tensioning roller. The adjusting component includes a rotating bracket and a locking pin. The rotating bracket is rotatably connected to one of the conveying rollers. Positioning holes adapted to the locking pin are evenly provided on the worktable along the rotation path of the rotating bracket. One side of the rotating bracket is rotatably connected to the tensioning roller, and the other side of the rotating bracket is provided with a locking groove adapted to the locking pin.

[0018] By adopting the above technical solution, the locking pin is inserted into the positioning hole through the locking groove to fix the rotating bracket. By aligning the locking groove with positioning holes at different positions, different degrees of tension can be achieved.

[0019] Optionally, the adjusting member is provided in two sets on the worktable, and positioning holes that are adapted to the locking pin are evenly opened on both sides of the worktable along the rotation path of the rotating bracket.

[0020] By adopting the above technical solution, two sets of adjustment components are set up symmetrically on both sides of the worktable and connected to the two ends of the tension roller, respectively, to ensure the stability of the tension roller adjustment work.

[0021] Optionally, the cutting mechanism includes mounting wheels and cutting blades for cutting paper. Two mounting frames are provided on the worktable, and two mounting wheels are correspondingly provided. The two mounting frames are symmetrically arranged on both sides of the paper conveying direction. The mounting wheels are rotatably mounted on the mounting frames. The cutting blades are fixedly mounted on the outer edges of the mounting wheels. A cutting groove is formed on the side wall of the conveying roller corresponding to the cutting blade. The cutting blade includes a fixing part and a disassembly part. A through hole is formed on the side wall of the mounting wheel. A sliding column is slidably disposed within the through hole. A protrusion is fixedly disposed on the side wall of the sliding column. A sliding groove is formed on the inner wall of the through hole corresponding to the protrusion. The protrusion is slidably disposed within the sliding groove. A pull rod is disposed within the sliding groove. One end of the pull rod is hinged to the inner wall of the sliding groove. The protrusion is close to the... A locking guide groove is formed on one side of the bottom wall of the sliding groove. An unlocking guide groove communicating with the locking guide groove is formed on the side of the protrusion near the bottom wall of the sliding groove. The depth of the locking guide groove is greater than the depth of the unlocking guide groove. A return spring is provided in the sliding groove. One end of the return spring is fixedly connected to the protrusion, and the other end of the return spring is fixedly connected to the inner wall of the sliding groove. A fixing part is provided at one end of the sliding column. A mounting insert is fixedly provided at the other end of the sliding column. A mounting slot adapted to the mounting insert is formed on the inner edge wall of the disassembly part. Connecting pieces are fixed on both symmetrical side walls of the fixing part. A connecting slot is formed on the disassembly part corresponding to the connecting piece. The mounting bracket is slidably set on the worktable. A fixing bolt for fixing the mounting bracket to the worktable is passed through the mounting bracket.

[0022] By adopting the above technical solution, the cutting blade is divided into a fixed part and a disassembly part. By adjusting the position of the pull rod in the locking guide groove and the unlocking guide groove, the position of the sliding column fixed in the through hole is adjusted, thereby realizing the fixing of the disassembly part with the mounting wheel or the separation of the disassembly part from the mounting wheel, which makes it convenient for workers to disassemble, repair or replace the disassembly part.

[0023] Optionally, the end of the sliding column away from the mounting insert has an internally hollow positioning groove, and the fixing part is fixedly provided with a positioning insert adapted to the positioning groove on the side near the sliding column. The positioning insert is inserted into the positioning groove from the groove opening and rotates within the positioning groove to be misaligned with the groove opening.

[0024] By adopting the above technical solution, a positioning insert that matches the positioning groove is fixedly installed on the side of the fixed part near the sliding column. The positioning insert is inserted into the positioning groove from the groove opening and rotates in the positioning groove to be misaligned with the groove opening, which makes it easy for the staff to separate the fixed part from the sliding column, and thus makes it easy for the staff to disassemble, repair or replace the fixed part.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The paper is transported by the tensioning conveyor mechanism and cut by the cutting mechanism. The cut paper waste strips enter the chip discharge duct through the chip inlet.

[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail as follows: Example 1 This application discloses an edge-cutting device for papermaking processing, such as... Figure 1 and Figure 2As shown, it includes a worktable 1, on which a tensioning conveying mechanism 2 is mounted. The tensioning conveying mechanism 2 includes conveying rollers 9 and tensioning rollers 10. Multiple conveying rollers 9 are provided, each rotatably mounted on the worktable 1 and parallel to the same vertical plane. An adjusting component 11 for adjusting the tensioning rollers 10 is provided on the worktable 1. The adjusting component 11 includes a V-block 12 and a tension spring 13. The V-block 12 is rotatably connected to the worktable 1, and the tensioning rollers 10 are rotatably connected to the V-block 12. The blocks 12 are perpendicular to each other in the same vertical plane. A first fixing block 14 is provided on the worktable 1, and a second fixing block 15 is fixedly provided on the V-block 12. One end of the tension spring 13 is connected to the first fixing block 14, and the other end of the tension spring 13 is connected to the second fixing block 15. A hook 16 is also provided on the V-block 12, and the hook 16 is rotatably connected to the second fixing block 15. A fixed shaft 17 is fixedly provided on the worktable 1, which cooperates with the hook 16 to keep the tension roller 10 in a relaxed state. An adjusting component 11 is provided on the worktable 1. There are two sets of V-blocks 12, which are rotatably connected to the two ends of the tensioning roller 10. The first fixed block 14, the second fixed block 15, the tension spring 13, and the hook 16 are each provided with two corresponding adjusting parts 11. When the tensioning conveying mechanism 2 is not working, the hook 16 hooks onto the right fixed shaft 17, and the tensioning roller is in a relaxed state. When the tensioning conveying mechanism 2 is running, the hook 16 disengages from the fixed shaft 17, and the tensioning roller 10 automatically tensions the conveyed item under the tension of the tension spring 13. The worktable 1 is equipped with a device for adjusting... The paper cutting mechanism 3 includes a mounting wheel 26 and a cutting blade 27 for cutting paper. The worktable 1 is provided with a mounting frame 28, and there are two mounting frames 28. There are two mounting wheels 26 corresponding to each mounting frame 28. The two mounting frames 28 are symmetrically arranged on both sides of the paper conveying direction to cut the two sides of the paper. The mounting wheels 26 are rotatably mounted on the mounting frames 28. The cutting blade 27 is fixedly mounted on the outer edge of the mounting wheel 26. The side wall of the conveying roller 9 is provided with a cutting groove 29 corresponding to the cutting blade 27.

[0029] like Figure 1 and Figure 3As shown, the cutting blade 27 includes a fixing part 30 and a disassembly part 31. A through hole 32 is provided on the side wall of the mounting wheel 26. A sliding column 33 is slidably disposed in the through hole 32. A protrusion 34 is fixedly disposed on the side wall of the sliding column 33. A sliding groove 35 is provided on the inner wall of the through hole 32 corresponding to the protrusion 34. The protrusion 34 is slidably disposed in the sliding groove 35. A pull rod 36 is disposed in the sliding groove 35. One end of the pull rod 36 is hinged to the inner wall of the sliding groove 35. A locking guide groove 37 is provided on the side of the protrusion 34 near the bottom wall of the sliding groove 35. An unlocking guide groove 38 is provided, which communicates with the locking guide groove 37. The depth of the locking guide groove 37 is greater than the depth of the unlocking guide groove 38. Based on the difference in depth between the locking guide groove 37 and the unlocking guide groove 38, the pull rod 36 travels along a specified trajectory. Since the depth of the locking guide groove 37 is greater than the unlocking guide groove 38, the pull rod 36 travels along the locking guide groove 37 when fixed. The connection between the locking guide groove 37 and the unlocking guide groove 38 is a guide groove 47. The pull rod 36 travels into the guide groove 47 and then hooks onto it, thus locking the cutting blade 27 on the mounting wheel 26. The cutting blade 27 needs to be removed from the mounting wheel. At time 26, the pull rod 36 moves along the unlocking guide groove 38, separating the pull rod 36 from the guide groove 47, thus facilitating the separation of the cutting blade 27 from the mounting wheel 26. A return spring 39 is provided in the sliding groove 35. One end of the return spring 39 is fixedly connected to the protrusion 34, and the other end of the return spring 39 is fixedly connected to the inner wall of the sliding groove 35. The fixing part 30 is provided at one end of the sliding column 33, and the other end of the sliding column 33 is fixedly provided with the mounting insert 40. The inner edge wall of the disassembly part 31 is provided with a mounting slot 41 that matches the mounting insert 40. The fixing part 30 has symmetrical side walls on both sides. Each part is fixed with a connecting piece 42. The disassembly and assembly part 31 has a connecting slot 43 corresponding to the connecting piece 42. The mounting bracket 28 is slidably mounted on the workbench 1. The mounting bracket 28 is provided with a fixing bolt 44 for fixing the mounting bracket 28 to the workbench 1. The end of the sliding column 33 away from the mounting insert 40 has a hollow positioning groove 45. The fixing part 30 is fixedly provided with a positioning insert 46 that matches the positioning groove 45 on the side near the sliding column 33. The positioning insert 46 is inserted into the positioning groove 45 through the groove opening of the positioning groove 45 and rotates within the positioning groove 45 to be misaligned with the groove opening of the positioning groove 45.

[0030] The implementation principle of the paper-making edge-trimming device in Embodiment 1 of this application is as follows: Paper is transported by a tensioning conveyor mechanism 2. When the tensioning conveyor mechanism 2 is not working, the hook 16 hooks the fixed shaft 17, and the tensioning roller 10 is in a relaxed state. When the tensioning conveyor mechanism 2 is running, the hook 16 disengages from the fixed shaft 17, and the tensioning roller 10 automatically tensions the conveyed paper under the tension of the tension spring 13. The paper is cut by the cutting mechanism 3, and the cut paper waste strips enter the chip discharge duct 6 through the chip inlet 7. The blower 5 blows air into the chip discharge duct 6, causing the gas flow rate inside the chip discharge duct 6 to be faster than the gas flow rate outside the chip discharge duct 6. The gas outside the chip discharge duct 6 enters the chip discharge duct 6 through the vent 8, thereby preventing it from entering the chip discharge duct 6. The paper waste strips are adsorbed on the side wall of the vent 8 of the chip removal duct 6 and are difficult to discharge. The gas carries the paper waste strips out of the chip removal duct 6 and they accumulate together. To prevent the paper waste from accumulating around the device and affecting the subsequent cutting of the paper edges, when installing the cutting blade 27, first insert the positioning insert 46 on the fixing part 30 into the positioning groove 45 through the groove opening of the positioning groove 45, and rotate it in the hollow positioning groove 45 to achieve the effect of misalignment with the groove opening of the positioning groove 45 and thus fix it. Then install the disassembly part 31 onto the mounting wheel 26. When installing the disassembly part 31 onto the mounting wheel 26, first insert the mounting insert 40 into the mounting slot 41. At this time, the sliding column 33 slides towards the fixing part 30, and the pull rod 36 moves along the locking guide groove 37. The device moves into the guide groove 47 at the connection between the locking guide groove 37 and the unlocking guide groove 38. Connecting pieces 42 are fixed on both symmetrical side walls of the fixing part 30. A connecting slot 43 is provided on the disassembly part 31 corresponding to the connecting piece 42. The connecting slot 43 is located at the cutting edge of the disassembly part 31. The fixing part 30 is pulled away from the mounting wheel 26. At this time, the return spring 39 is stretched, and the pull rod 36 disengages from the guide groove 47, moving along the unlocking guide groove 38 and finally returning to its initial position. The connecting piece 42 is inserted from the cutting edge of the disassembly part 31 into the connecting slot 43, thus fixing the disassembly part 31 to the fixing part 30. After the connecting piece 42 is inserted into the connecting slot 43, the side of the connecting piece 42 closest to the slot takes over the work of the blade. After connecting the slot 43, the pull rod 36 travels along the locking guide groove 37 to the guide groove 47, thus fixing the disassembly part 31 and the fixing part 30 on the mounting wheel 26. When it is necessary to remove the disassembly part 31 and the fixing part 30 from the mounting wheel 26, the fixing part 30 is pulled away from the mounting wheel 26. At this time, the return spring 39 is stretched, the pull rod 36 is disengaged from the guide groove 47, travels along the unlocking guide groove 38 and finally returns to the initial position, separating the connecting piece 42 from the connecting slot 43. The fixing part 30 is then pulled to make the mounting insert 40 disengage from the mounting slot 41, thereby separating the disassembly part 31 from the mounting part. Finally, the positioning insert 46 is rotated in the positioning groove 45 to the slot opening of the matching positioning groove 45, thereby separating the fixing part 30 from the mounting wheel 26.

[0031] Example 2 The difference from Example 1 is that, as Figure 4 As shown, the tensioning conveyor mechanism 2 includes conveying rollers 9 and tensioning rollers 10. Multiple conveying rollers 9 are provided, each rotatably mounted on the worktable 1 and parallel to the same vertical plane. A mounting block 48 is provided on the worktable 1, and the tensioning roller 10 is rotatably connected to the mounting block 48. An adjusting component 11 for adjusting the tensioning roller 10 is provided on the worktable 1. The adjusting component 11 includes adjustable bolts 18 and fixing blocks 19. The fixing blocks 19 have multiple mounting holes 20 for fixing the fixing blocks 19 to the worktable 1. Bolts are passed through the mounting holes 20 to secure the tensioning roller 10. The fixing block 19 is fixed to the workbench 1. The fixing block 19 is provided with a guide rail 21. The mounting block 48 slides along the guide rail 21 and is connected to the fixing block 19. One end of the adjustable bolt 18 extends into the guide rail 21 and is rotatably connected to the mounting block 48. The side wall of the adjustable bolt 18 is threadedly connected to the fixing block 19. Two mounting blocks 48 are provided on the workbench 1. The two mounting blocks 48 are symmetrically arranged on the workbench 1. The two mounting blocks 48 are rotatably connected to the two ends of the tension roller 10 respectively. Two sets of adjusting parts 11 are provided on the workbench 1 corresponding to the two mounting blocks 48.

[0032] The implementation principle of the edge trimming device for papermaking in Embodiment 2 of this application is as follows: the fixed block 19 is fixed on the workbench 1 through the mounting hole 20. The fixed block 19 is provided with a guide rail 21, which plays a guiding role in the lateral movement of the tension roller 10. The position of the tension roller 10 can be changed by adjusting the adjustable bolt 18, thereby achieving tensioning of the conveyed paper.

[0033] Example 3 The difference from Example 1 is that, as Figure 5 As shown, the tensioning conveying mechanism 2 includes a conveying roller 9 and a tensioning roller 10. Multiple conveying rollers 9 are provided, and each conveying roller 9 is rotatably mounted on the worktable 1 and is parallel to the same vertical plane. The worktable 1 is provided with an adjusting component 11 for adjusting the tensioning roller 10. The adjusting component 11 includes a rotating bracket 22 and a locking pin 23. The rotating bracket 22 is rotatably connected to a conveying roller 9. The worktable 1 is provided with positioning holes 24 that are adapted to the locking pin 23 evenly along the rotation path of the rotating bracket 22. One side of the rotating bracket 22 is rotatably connected to the tensioning roller 10, and the other side of the rotating bracket 22 is provided with a locking groove 25 that is adapted to the locking pin 23. Two sets of adjusting components 11 are provided on the worktable 1. The symmetrical sides of the worktable 1 are provided with positioning holes 24 that are adapted to the locking pin 23 evenly along the rotation path of the rotating bracket 22.

[0034] The implementation principle of the paper-making edge-cutting device in Embodiment 3 of this application is as follows: the locking pin 23 is inserted into the positioning hole 24 through the locking groove 25 to fix the rotating bracket 22. According to different situations during paper feeding, the operator connects the locking groove 25 with the positioning hole 24 at different positions to achieve different degrees of tension on the fed paper.

[0035] 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.
