Description

Technical Field

[0001] This invention relates to the field of nylon filament processing technology, specifically to a shearing device and method for nylon filament processing. Background Technology

[0002] Nylon filaments are widely used in various industries due to their high mechanical strength, high softening point, heat resistance, low coefficient of friction, wear resistance, good electrical insulation, self-extinguishing properties, non-toxicity, odorlessness, good weather resistance, and poor dyeability. The demand for nylon filaments is very high, so many chemical companies produce them in large quantities. During production, nylon filaments are first extruded, then wound up. When the nylon filaments are wound to a certain extent, they need to be cut.

[0003] Currently, Chinese patent application number CN202023060331.4 discloses a shearing device for processing nylon filaments, including a worktable. A shearing mechanism is fixedly connected to the center of the upper surface of the worktable. The shearing mechanism includes a fixed frame, an electric telescopic rod, a rack, a fixed plate, a driving gear, a driven gear, a rotating shaft, a first connecting rod, a second connecting rod, a third connecting rod, and a shearing blade. The center of the upper surface of the worktable is fixedly connected to the lower surface of the fixed frame. A fixed plate is fixedly connected to the inner wall of the fixed frame. Rotating shafts are symmetrically fixedly connected to the left and right sides of the fixed plate. One of the rotating shafts passes through the center of the driving gear and is rotatably connected to it. The other shaft... The rotating shaft passes through the center of the driven gear and is rotatably connected to it. The driving gear meshes with the driven gear. The side of the driving gear away from the driven gear meshes with the rack. The upper surface of the rack is fixedly connected to the lower surface of the electric telescopic rod. The upper surface of the electric telescopic rod is fixedly connected to the top of the fixed frame. A first connecting rod is fixedly connected to both the driving gear and the driven gear. The two first connecting rods are symmetrically arranged. The lower end of the first connecting rod is movably connected to one end of the second connecting rod. The other end of the second connecting rod is fixedly connected to one side of the shearing blade. The second connecting rod is movably connected to one end of the third connecting rod. The other end of the third connecting rod is movably connected to the fixed plate.

[0004] The shearing mechanism is symmetrically equipped with fixing mechanisms on both sides. Each fixing mechanism includes a fixing block, a sliding rod, a handle, a spring, a second arc-shaped fixing block, and a fixing seat. The upper surface of the worktable is fixedly connected to the lower surface of the fixing block. A fixing seat is fixedly connected to the lower end of the inner wall of the fixing block. A third anti-slip pad is fixedly connected to the upper surface of the fixing seat. A second arc-shaped fixing block is provided on both sides and the upper side inside the fixing block. A second anti-slip pad is fixedly connected to the side of the second arc-shaped fixing block away from the inner wall of the fixing block. The other side of the second arc-shaped fixing block is fixedly connected to one end of the sliding rod. The sliding rod passes through the fixing block and is slidably connected to it. A handle is fixedly connected to the other end of the sliding rod. A spring is sleeved on the sliding rod. One end of the spring is fixedly connected to the inner wall of the fixing block, and the other end of the spring is fixedly connected to the side of the second arc-shaped fixing block near the inner wall of the fixing block.

[0005] In the aforementioned prior art, during use, it is necessary to manually pass one end of the nylon filament through a fixed block, a fixed frame, and another fixed block in sequence, and then cut the nylon filament with a shearing blade inside the fixed frame. However, when manually passing one end of the nylon filament through the fixed frame, the shearing blade is located inside the fixed frame, which can easily scratch workers, resulting in low safety. Therefore, the applicant has developed a new technical solution in actual production to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a shearing device and method for processing nylon filaments, which has the advantage of improving safety during use.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This invention provides a shearing device for processing nylon filaments, including a worktable, a turntable, and two support plates disposed on the top of the worktable. The top ends of the two support plates are connected by a connecting plate, and the two support plates are positioned opposite each other. A first cylinder is disposed on the connecting plate, and one end of the piston rod of the first cylinder is provided with a mounting plate located below the connecting plate. A cutting blade is disposed at the bottom end of the mounting plate. The turntable is located between the two support plates, and a rotating groove is coaxially formed on the turntable. A column is rotatably connected in the rotating groove, and the bottom end of the column is fixedly connected to the top of the worktable. The column is located directly below the cutting blade. Two support columns are disposed on the top of the worktable, facing each other, and a first sleeve and a second sleeve are horizontally disposed on the top ends of the two support columns, respectively. Two clamping members are disposed on the top of the turntable for clamping and fixing the nylon filaments, and the two clamping members are disposed opposite each other. A driving member is disposed on the worktable for driving the turntable to rotate on the columns.

[0009] By adopting the above technical solution, the two clamping components are located near the first sleeve and the second sleeve, respectively. In use, one end of the nylon filament is passed through the first sleeve, and then the clamping component on the turntable near the first sleeve clamps and fixes the nylon filament passing through the first sleeve. Then, the turntable is driven by the drive component to rotate 180 degrees on the column, so that the two clamping components are swapped. At this time, because the clamping component near the first sleeve clamps and fixes one end of the nylon filament, when the turntable rotates 180 degrees and the two clamping components are swapped, the nylon filament will be located on the turntable. Then, the clamping component is released from the nylon filament, and then one end of the nylon filament is passed through the second sleeve. At this time, the nylon filament will be horizontally located between the column and the cutting blade. There is no need to manually pass one end of the nylon filament between the cutting blade and the column, which improves the safety of use.

[0010] When it is necessary to cut nylon filaments, simply clamp and fix the nylon filaments with the clamping device near the first sleeve, then open the first cylinder. The piston rod of the first cylinder pushes the mounting plate to move the cutting blade downwards, and the nylon filaments can be cut by the cutting blade.

[0011] After cutting, the cut nylon filament is pulled out from the second sleeve, and then the turntable is driven to rotate 180 degrees on the column by the drive component, so that the two clamping parts are swapped. After the swap, the clamping parts are released from the nylon filament, and then one end of the nylon filament is passed through the second sleeve. After cutting, there is no need to manually pass one end of the nylon filament between the cutting blade and the column, which improves the safety of use and makes it simple and convenient to use.

[0012] Preferably, both clamping components include a stop cylinder vertically disposed at the top of the turntable and a threaded cylinder coaxially sleeved within the stop cylinder. Each of the two threaded cylinders is threaded with a screw, the bottom end of which is rotatably connected to the top of the turntable. Two vertical grooves are vertically formed on the outer walls of both stop cylinders. A horizontal column located within the vertical groove is horizontally disposed on the outer wall of each of the two threaded cylinders near one end of the two vertical grooves. A pressure ring is coaxially sleeved on the outer wall of each of the two stop cylinders, and the inner wall of the pressure ring is fixedly connected to the end of the two horizontal columns away from the threaded cylinder. A drive shaft is coaxially disposed at the bottom end of each of the two screws, and the bottom ends of both drive shafts pass through the turntable and are each provided with a first gear located below the turntable. A power component is provided on the worktable to drive the two first gears to rotate respectively.

[0013] Preferably, the power component includes a U-shaped first push plate and a second push plate that are horizontally slidably connected to the top of the worktable. The turntable has a movable plate that is horizontally slidably connected to one end near the two first gears. The two movable plates are provided with racks that mesh with the first gears on the side near the first gears. The two movable plates are located inside the first push plate and the second push plate, respectively. The worktable is provided with two second cylinders for pushing the first push plate and the second push plate to move horizontally, respectively.

[0014] Preferably, the bottom end of the turntable is rotatably connected to two fixed blocks, and the two fixed blocks correspond one-to-one with the two moving plates, and are both located on the side of the moving plates away from the rack. The side of the two fixed blocks near the moving plates is provided with a compression spring, and the side of the two moving plates away from the rack is hinged with a connecting block. The end of the two compression springs away from the fixed blocks is fixedly connected to the connecting block.

[0015] Preferably, each of the two connecting blocks has a horizontally arranged sliding column at one end near the compression spring, and each of the two fixing blocks has a circular groove at one end near the compression spring for the sliding column to pass through horizontally. The two sliding columns are respectively located inside the two compression springs.

[0016] Preferably, a third cylinder is vertically provided on one side of the workbench, and a U-shaped frame is provided at one end of the piston rod of the third cylinder. Two rotating rollers are rotatably connected between opposite sides of the inner wall of the U-shaped frame, and the two rotating rollers are opposite each other. One end of the nylon thread passes through the two rotating rollers. The U-shaped frame is located above the side of the first sleeve away from the second sleeve.

[0017] Preferably, the first sleeve has a first guide tube on the side near the U-shaped frame, and the inner diameter of the first guide tube on the side away from the first sleeve is larger than the inner diameter of the first guide tube on the side near the first sleeve. The inner diameter of the first guide tube on the side near the first sleeve is the same as the inner diameter of the first sleeve. The second sleeve has a second guide tube on the side near the first sleeve, and the inner diameter of the second guide tube on the side away from the second sleeve is larger than the inner diameter of the second guide tube on the side near the second sleeve. The inner diameter of the second guide tube on the side near the second sleeve is the same as the inner diameter of the second sleeve.

[0018] Preferably, the driving component includes a driving cylinder coaxially fixedly connected to the bottom end of the turntable. The driving cylinder is coaxial with the column. A second gear is coaxially provided on the outer wall of the driving cylinder. A servo motor is provided at the top of the worktable, and a third gear meshing with the second gear is provided at one end of the rotating shaft of the servo motor.

[0019] Preferably, the workbench is provided with support legs at the four corners of its bottom, and the bottom of each of the four support legs is provided with anti-slip pads. The top of the column is provided with a cutting groove that cooperates with the cutting blade.

[0020] Another objective of this invention is to provide a method of using a shearing device for processing nylon filaments. Two clamping members are located near a first sleeve and a second sleeve, respectively. In use, one end of the nylon filament is passed through the first sleeve, and then the clamping member on the turntable near the first sleeve clamps and fixes the nylon filament passing through the first sleeve. Then, the turntable is driven to rotate 180 degrees on the column by a driving member, so that the two clamping members are swapped. At this time, because the clamping member near the first sleeve clamps and fixes one end of the nylon filament, when the turntable rotates 180 degrees and the two clamping members are swapped, the nylon filament will be located on the turntable. Then, the clamping members are released from the nylon filament, and then one end of the nylon filament is passed through the second sleeve. At this time, the nylon filament will be horizontally located between the column and the cutting blade.

[0021] When it is necessary to cut nylon filaments, simply clamp and fix the nylon filaments with two clamping devices, then open the first cylinder. The piston rod of the first cylinder pushes the mounting plate and moves the cutting blade downwards. At this time, the nylon filaments can be cut by the cutting blade.

[0022] After cutting, release the clamping device near the second sleeve from the nylon filament, then pull the cut nylon filament out of the second sleeve. Then, drive the turntable to rotate 180 degrees on the column via the drive unit, so that the two clamping devices are swapped. After the swap, release the other clamping device from the nylon filament, and then pass one end of the nylon filament through the second sleeve.

[0023] The beneficial effects of this invention are as follows: the two clamping members are respectively close to the first sleeve and the second sleeve. In use, one end of the nylon filament is passed through the first sleeve, and then the clamping member on the turntable close to the first sleeve clamps and fixes the nylon filament passing through the first sleeve. Then, the turntable is driven to rotate 180 degrees on the column by the driving member, so that the two clamping members are swapped. At this time, because the clamping member close to the first sleeve clamps and fixes one end of the nylon filament, when the turntable rotates 180 degrees and the two clamping members are swapped, the nylon filament will be located on the turntable. Then, the clamping member is released from the nylon filament, and then one end of the nylon filament is passed through the second sleeve. At this time, the nylon filament will be horizontally located between the column and the cutting blade. There is no need to manually pass one end of the nylon filament between the cutting blade and the column, which improves the safety of use.

[0024] When it is necessary to cut nylon filaments, simply clamp and fix the nylon filaments with two clamping devices, then open the first cylinder. The piston rod of the first cylinder pushes the mounting plate and moves the cutting blade downwards. At this time, the nylon filaments can be cut by the cutting blade.

[0025] After cutting, release the clamping device near the second sleeve from the nylon filament, then pull the cut nylon filament out of the second sleeve. Then, drive the turntable to rotate 180 degrees on the column via the drive unit, causing the two clamping devices to switch positions. After the switching, release the other clamping device from the nylon filament, and then pass one end of the nylon filament through the second sleeve. After cutting, there is no need to manually pass one end of the nylon filament between the cutting blade and the column, which improves safety and makes it simple and convenient to use.

[0035] 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.

[0036] Example 1: A shearing device for processing nylon yarn, such as Figure 1 and Figure 2 The system includes a workbench 1, a turntable 2, and two support plates 3 set at the top of the workbench 1. The tops of the two support plates 3 are connected by a connecting plate 4. The two support plates 3 are opposite each other. A first cylinder 5 is provided on the connecting plate 4, and a mounting plate 6 located below the connecting plate 4 is provided at one end of the piston rod of the first cylinder 5. A cutting blade 7 is provided at the bottom end of the mounting plate 6. The turntable 2 is located between the two support plates 3, and a rotating groove 8 is coaxially opened on the turntable 2. A column 9 is rotatably connected in the rotating groove 8, and the bottom end of the column 9 is fixedly connected to the top of the workbench 1. The column 9 is located directly below the cutting blade 7. Two support columns 10 are provided at the top of the workbench 1, which are opposite each other. A first sleeve 12 and a second sleeve 13 are horizontally provided at the top of the two support columns 10, respectively. Two clamping parts for clamping and fixing nylon filaments are provided at the top of the turntable 2. The two clamping parts are arranged opposite each other. A driving part for driving the turntable 2 to rotate on the column 9 is provided on the workbench 1.

[0037] like Figure 1 and Figure 2Two clamping members are located near the first sleeve 12 and the second sleeve 13, respectively. In use, one end of the nylon thread is passed through the first sleeve 12, and then clamped and fixed by the clamping member on the turntable 2 near the first sleeve 12. Then, the turntable 2 is driven to rotate 180 degrees on the column 9 by a drive unit, causing the two clamping members to switch positions. Because the clamping member near the first sleeve 12 is still clamping and fixing one end of the nylon thread, when the turntable 2 rotates 180 degrees and the two clamping members switch positions, the nylon thread will be located on the turntable 2 (e.g., ...). Figure 6 Then, release the clamping device from the nylon filament, and then pass one end of the nylon filament through the second sleeve 13. At this time, the nylon filament will be horizontally positioned between the column 9 and the cutting blade 7 (e.g., Figure 1 This eliminates the need for manual insertion of one end of the nylon filament between the cutting blade 7 and the column 9, improving safety during use.

[0038] When it is necessary to cut nylon filaments, simply clamp and fix the nylon filaments with two clamping pieces, then open the first cylinder 5. The piston rod of the first cylinder 5 pushes the mounting plate 6 to drive the cutting blade 7 to move downwards. At this time, the nylon filaments can be cut by the cutting blade 7.

[0039] After cutting, release the clamping member near the second sleeve 13 from the nylon filament, and then pull the cut nylon filament out of the second sleeve 13. Then, drive the turntable 2 to rotate 180 degrees on the column 9 through the drive component, so that the two clamping members are swapped. After the swap, release the clamping member from the nylon filament, and then pass one end of the nylon filament through the second sleeve 13. After cutting, there is no need to manually pass one end of the nylon filament between the cutting blade 7 and the column 9, which improves the safety of use and makes it simple and convenient to use.

[0040] like Figure 1 and Figure 3 and Figure 4 Both clamping components include a stop cylinder 14 vertically mounted at the top of the turntable 2 and a threaded cylinder 15 coaxially sleeved inside the stop cylinder 14. Each threaded cylinder 15 is threaded with a screw 16, the bottom ends of which are rotatably connected to the top of the turntable 2. Each stop cylinder 14 has two vertical grooves 17 vertically formed on its outer wall. Each threaded cylinder 15 has a horizontal column 18 located within the vertical groove 17 at one end of its outer wall near the groove. Each stop cylinder 14 has a pressure ring 19 coaxially sleeved on its outer wall, and the inner wall of the pressure ring 19 is fixedly connected to the end of the horizontal column 18 away from the threaded cylinder 15. Each screw 16 has a drive shaft 20 coaxially mounted at its bottom end, and the bottom ends of both drive shafts 20 pass through the turntable 2 and each has a first gear 21 located below the turntable 2. The worktable 1 is equipped with a power component for driving the two first gears 21 to rotate.

[0041] like Figure 1 and Figure 3 and Figure 4 After one end of the nylon filament is passed through the first sleeve 12, the end of the nylon filament is located on the side of the stop 14 near the first sleeve 12 and is in contact with the stop 14. At this time, the end of the nylon filament is located below the pressure ring 19. Then, the first gear 21 near the first sleeve 12 is driven to rotate by the power component. The first gear 21 drives the screw 16 to rotate through the transmission shaft 20. The screw 16, through its cooperation with the threaded cylinder 15 and the cooperation between the horizontal column 18 and the vertical groove 17 on the threaded cylinder 15, can make the threaded cylinder 15 move vertically downward or upward. When the threaded cylinder 15 moves vertically, the pressure ring 19 will follow the threaded cylinder 15 to move vertically through the horizontal column 18. When the threaded cylinder 15 moves vertically downward until the bottom end of the pressure ring 19 contacts the nylon filament and presses the nylon filament tightly on the turntable 2, the clamping and fixing of the nylon filament is completed. It is simple and convenient to use.

[0042] like Figure 1 and Figure 2 and Figure 3 and Figure 4 The power components include a U-shaped first push plate 22 and a second push plate 23 that are horizontally slidably connected to the top of the worktable 1. The turntable 2 has a moving plate 24 that is horizontally slidably connected to one end of each of the two first gears 21. Each of the two moving plates 24 has a rack 25 that meshes with the first gear 21 on the side of each moving plate 24 that is close to the first gear 21. The two moving plates 24 are located inside the first push plate 22 and the second push plate 23, respectively. The worktable 1 is provided with two second cylinders 26 for pushing the first push plate 22 and the second push plate 23 to move horizontally, respectively.

[0043] like Figure 1 and Figure 2 and Figure 3 and Figure 4 The first push plate 22 is positioned close to the first sleeve 12, and the second push plate 23 is positioned close to the second sleeve 13. By opening one of the second cylinders 26, the piston rod of one of the second cylinders 26 pushes the first push plate 22 to move horizontally away from the column 9. When one end of the inner side of the first push plate 22 contacts the moving plate 24 inside the first push plate 22, as the first push plate 22 moves, the first push plate 22 will drive the moving plate 24 inside the first push plate 22 to move away from the column 9. At this time, the rack 25 on the moving plate 24 will drive the transmission shaft 20 to rotate through the first gear 21 meshing with it. At this time, the transmission shaft 20 will drive the screw 16 to rotate inside the stop cylinder 14, so that the threaded cylinder 15, the horizontal column 18, and the pressure ring 19 move vertically downward to clamp and fix the nylon thread.

[0044] When turntable 2 rotates 180 degrees, causing the two baffles 14 to switch positions, the two moving plates 24 will also switch positions. At this time, the moving plate 24 located in the first push plate 22 will move to the second push plate 23, and the moving plate 24 in the second push plate 23 will move to the first push plate 22. At this time, by opening another second cylinder 26, the piston rod of the other second cylinder 26 pushes the second push plate 23 to move horizontally towards the column 9. When one end of the second push plate 23 is switched to the second push plate 24, the moving plate 24 will move towards the column 9. After the movable plate 24 inside 3 makes contact, as the second push plate 23 moves, the second push plate 23 will drive the movable plate 24 inside the second push plate 23 to move closer to the column 9. At this time, the rack 25 on the movable plate 24 will drive the transmission shaft 20 to rotate in the opposite direction through the first gear 21 meshing with it, so that the threaded cylinder 15, the horizontal column 18 and the pressure ring 19 move vertically upward, releasing the clamping and fixing of the nylon thread. The first push plate 22 and the second push plate 23 will not affect the rotation of the turntable 2.

[0045] After the clamping and fixing of the nylon filament is released, during the rotation of the turntable 2, when the two moving plates 24 move out of the first push plate 22 and the second push plate 23 respectively, the first push plate 22 and the second push plate 23 are moved back to their original positions by the two second cylinders 26 respectively, so that the two moving plates 24 after the change can enter the first push plate 22 and the second push plate 23 respectively, which is simple and convenient to use.

[0046] like Figure 3 and Figure 5 Two fixed blocks 27 are rotatably connected to the bottom of the turntable 2, and each fixed block 27 corresponds to one of the two movable plates 24, and is located on the side of the movable plate 24 away from the rack 25. A compression spring 28 is provided on the side of each fixed block 27 near the movable plate 24. A connecting block 29 is hinged to the side of each movable plate 24 away from the rack 25. The ends of the two compression springs 28 away from the fixed blocks 27 are fixedly connected to the connecting blocks 29. The purpose of this arrangement is that when the movable plate 24 moves horizontally on the turntable 2, the pressure ring 19 moves vertically downward to clamp the nylon thread, or the pressure ring... When the 19 moves vertically upward and releases the clamp on the nylon thread, the connecting block 29 will pass by the side of the rotation point between the fixed block 27 and the turntable 2. When the connecting block 29 passes by the side of the rotation point between the fixed block 27 and the turntable 2, the compression spring 28 will be compressed. After the connecting block 29 passes by the side of the rotation point between the fixed block 27 and the turntable 2, the compression spring 28 will rebound. At this time, through the cooperation of the compression spring 28, the fixed block 27, the connecting block 29 and the moving plate 24, the sliding of the moving plate 24 on the turntable 2 during the rotation of the turntable 2 can be reduced, making it simple and convenient to use.

[0047] like Figure 5Each of the two connecting blocks 29 has a horizontally arranged sliding column 30 at one end near the compression spring 28, and each of the two fixing blocks 27 has a circular groove 31 at one end near the compression spring 28 for one end of the sliding column 30 to pass through horizontally. The two sliding columns 30 are located inside the two compression springs 28 respectively. The purpose of this arrangement is to reduce the bending deformation of the compression spring 28 by means of the sliding column 30, making it simple and convenient to use.

[0048] like Figure 1 and Figure 2 A third cylinder 32 is vertically provided on one side of the workbench 1, and a loop frame 33 is provided at one end of the piston rod of the third cylinder 32. Two rotating rollers 34 are rotatably connected between opposite sides of the inner wall of the loop frame 33, and the two rotating rollers 34 are opposite each other. One end of the nylon wire passes through the two rotating rollers 34. The loop frame 33 is located above the side of the first sleeve 12 away from the second sleeve 13.

[0049] like Figure 1 and Figure 2 When passing one end of the nylon filament through the first sleeve 12, the nylon filament is first passed through the two rotating rollers 34. Then, the nylon filament end that has passed through the two rotating rollers 34 is passed through the first sleeve 12. Then, the clamping device on the turntable 2 near the first sleeve 12 clamps and fixes the nylon filament end that has passed through the first sleeve 12. The drive unit drives the turntable 2 to rotate 180 degrees on the column 9, so that the two clamping devices are interchanged. During the process, the piston rod of the third cylinder 32 drives the loop frame 33 to move vertically downward, which allows the nylon filament required for the rotation of the turntable 2 to be released. When one end of the nylon filament is passed through the second sleeve 13 and then wound and collected, the piston rod of the third cylinder 32 first drives the loop frame 33 to move vertically upward. At this time, the nylon filament on one side of the first sleeve 12 will bend upward, which increases the length of the nylon filament on the side of the first sleeve 12 away from the second sleeve 13. It is simple and convenient to use.

[0050] like Figure 2The first sleeve 12 has a first guide tube 35 on the side near the U-shaped frame 33. The inner diameter of the first guide tube 35 on the side away from the first sleeve 12 is larger than the inner diameter of the side of the first guide tube 35 near the first sleeve 12. The inner diameter of the side of the first guide tube 35 near the first sleeve 12 is the same as the inner diameter of the first sleeve 12. The second sleeve 13 has a second guide tube 36 on the side near the first sleeve 12. The inner diameter of the second guide tube 36 on the side away from the second sleeve 13 is larger than the inner diameter of the side of the second guide tube 36 near the second sleeve 13. The inner diameter of the side of the second guide tube 36 near the second sleeve 13 is the same as the inner diameter of the second sleeve 13. The purpose of this arrangement is that one end of the nylon thread can be easily passed through the first sleeve 12 through the first guide tube 35, and one end of the nylon thread can be easily passed through the second sleeve 13 through the second guide tube 36, making it simple and convenient to use.

[0051] like Figure 2 and Figure 3 The driving component includes a driving cylinder 37 coaxially fixedly connected to the bottom end of the turntable 2. The driving cylinder 37 is coaxial with the column 9. A second gear 38 is coaxially provided on the outer wall of the driving cylinder 37. A servo motor 39 is provided at the top of the worktable 1, and a third gear 40 that meshes with the second gear 38 is provided at one end of the rotating shaft of the servo motor 39.

[0052] like Figure 2 and Figure 3 When it is necessary to drive the turntable 2 to rotate, simply turn on the servo motor 39. At this time, the rotating shaft of the servo motor 39 will drive the third gear 40 to rotate. The third gear 40 will then drive the drive cylinder 37 to rotate through the second gear 38 meshing with it. The drive cylinder 37 will then drive the turntable 2 to rotate on the column 9. It is simple and convenient to use.

[0053] like Figure 1 The workbench 1 has four support legs 41 at the bottom corners, and each of the four support legs 41 has an anti-slip pad 42 at the bottom. The top of the column 9 has a cutting groove 43 that cooperates with the cutting blade 7. The cutting groove 43 that cooperates with the cutting blade 7 makes it easy for the cutting blade 7 to cut nylon filaments, which is simple and convenient to use.

[0054] Example 2: A method of using a shearing device for processing nylon filaments, comprising Example 1, wherein two clamping members are respectively located near the first sleeve 12 and the second sleeve 13. In use, one end of the nylon filament is passed through the first sleeve 12, and then the clamping member on the turntable 2 near the first sleeve 12 clamps and fixes the nylon filament passing through the first sleeve 12. Then, the turntable 2 is driven to rotate 180 degrees on the column 9 by the driving member, so that the two clamping members are swapped. At this time, because the clamping member near the first sleeve 12 clamps and fixes one end of the nylon filament, when the turntable 2 rotates 180 degrees and the two clamping members are swapped, the nylon filament will be located on the turntable 2. Then, the clamping member is released from the nylon filament, and then one end of the nylon filament is passed through the second sleeve 13. At this time, the nylon filament will be horizontally located between the column 9 and the cutting blade 7.

[0055] When it is necessary to cut nylon filaments, simply clamp and fix the nylon filaments with two clamping pieces, then open the first cylinder 5. The piston rod of the first cylinder 5 pushes the mounting plate 6 to drive the cutting blade 7 to move downwards. At this time, the nylon filaments can be cut by the cutting blade 7.

[0056] After cutting, release the clamping member near the second sleeve 13 from the nylon filament, then pull the cut nylon filament out of the second sleeve 13, and then drive the turntable 2 to rotate 180 degrees on the column 9 through the drive member, so that the two clamping members are swapped. After the swap, release the clamping member from the nylon filament, and then pass one end of the nylon filament through the second sleeve 13.

[0057] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
