[0002] Chemical fiber paper tubes refer to paper tubes used for winding chemical fibers, spinning, texturing, etc. During the production process of chemical fiber paper tubes, it is often necessary to cut the processed whole chemical fiber paper tube into several segments that meet the requirements. However, in actual cutting, existing cutting equipment cannot accurately position the whole chemical fiber paper tube to its correct length, and dust and other adhering substances on the outer surface of the chemical fiber paper tube can also adversely affect the cutting, resulting in poor overall cutting quality, which needs improvement. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a cutting device for chemical fiber paper tubes, which can achieve accurate length limiting and placement of chemical fiber paper tubes and double cleaning treatment, so as to solve the above problems.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a slitting device for chemical fiber paper tubes, comprising an operating table, a back plate vertically fixed at the rear end of the top of the operating table, a top plate fixedly fixed at the top end of the back plate facing forward, a first hydraulic cylinder vertically fixed at one end of the top plate, the piston rod of the first hydraulic cylinder facing downward and fixedly connected to an inverted U-shaped lifting frame, a horizontally rotatable rotating shaft between the bottom ends of the two vertical parts of the lifting frame, a cutting saw blade coaxially fixedly sleeved on the rotating shaft, and a first motor drivingly connected to one end of the shaft, and a detachable part of the operating table on one side of the cutting saw blade. The machine is equipped with a movable seat, and a second hydraulic cylinder is horizontally fixed on the operating platform on the other side. Cleaning rings are fixed on both the left and right sides of the top of the movable seat, and a limiting sleeve is fixed on the upper left and right side of the middle. The cleaning ring and the limiting sleeve are coaxially arranged, and a cleaning brush is fixed on the inner ring of the cleaning ring. The bristles of the cleaning brush face the center of the cleaning ring. The piston rod of the second hydraulic cylinder faces the direction of the cutting saw blade and is fixedly connected to a positioning plate. The bottom of the positioning plate is slidably connected to the top of the operating platform. The upper left and right side of the front side of the operating platform corresponding to the positioning plate is marked with scale.
[0005] Preferably, the bottom of the movable seat is provided with a square mounting groove, and several locking blind holes are provided on the left and right walls of the mounting groove. A mounting block is fixed on the top of the operating table corresponding to the mounting groove. Movable grooves are provided on both the left and right sides of the mounting block. Electric push rods are embedded in the left and right ends of the mounting block. The telescopic end of the electric push rod extends into the movable groove on the same side and is fixedly connected to a locking plate. Several locking rods arranged in a rectangular array are fixed on the side of the locking plate away from the corresponding electric push rod. The movable seat is fitted onto the outside of the mounting block through the mounting groove. The locking plate abuts against the groove wall of the mounting groove on the same side. The locking rods correspond one-to-one with the locking blind holes on the same side and are inserted into the groove.
[0006] Preferably, the mounting block is adapted to the mounting groove.
[0007] Preferably, the locking rod is adapted to the corresponding locking blind hole.
[0008] Preferably, the bottom of the positioning plate is fixedly connected to an inverted T-shaped slider, and the top of the operating table corresponding to the slider is provided with a matching inverted T-shaped groove along the left and right direction, and the slider is slidably disposed on the groove.
[0009] Preferably, a third hydraulic cylinder is horizontally fixed on the side of the top plate away from the first hydraulic cylinder along the left-right direction. The piston rod of the third hydraulic cylinder faces away from the first hydraulic cylinder and is fixedly connected to a second motor. The output shaft of the second motor faces away from the first hydraulic cylinder and is fixedly connected to a rotating rod. A baffle is fixedly connected to the bottom end of the rotating rod.
[0010] The beneficial effects of this utility model are as follows: When slitting chemical fiber paper tubes, the positioning plate can be moved left and right by extending and retracting the piston rod of the second hydraulic cylinder according to the required length of the chemical fiber paper tube. This allows for flexible adjustment of the distance between the positioning plate and the cutting saw blade. Combined with the scale on the operating table, the positioning plate can be quickly adjusted into place. Then, the worker feeds the original chemical fiber paper tube from the side of the movable seat away from the positioning plate, allowing the paper tube to pass through the left cleaning ring, the limiting sleeve, and the right cleaning ring on the movable seat before abutting against the positioning plate. During this process, the bristles of the cleaning brushes on the two cleaning rings can perform a double cleaning of the paper tube, effectively removing dirt from its surface and preventing adverse effects on subsequent cutting. This further ensures the cutting effect, while the limiting sleeve, which is compatible with the paper tube, effectively limits its placement. Next, the first hydraulic cylinder is operated, extending its piston rod, which moves the lifting frame and cutting saw blade downwards. Simultaneously, the first motor is activated, driving the cutting saw blade to rotate, thus completing the cutting of the synthetic fiber paper tubes. After completion, the cut synthetic fiber paper tubes of a fixed length are removed by the operator, and the remaining synthetic fiber paper tubes continue to move towards the positioning plate until they re-abut against the positioning plate, at which point the cutting process continues as described above. When the required length of the synthetic fiber paper tube changes, the position of the positioning plate can be adjusted again by extending and retracting the piston rod of the second hydraulic cylinder. When the required outer diameter of the synthetic fiber paper tube changes, the movable seat can be disassembled and replaced using the detachable connection between the movable seat and the operating table. In this way, accurate length-limiting placement and double cleaning treatment can be achieved for synthetic fiber paper tubes of different outer diameters, effectively improving the cutting quality and making the device more practical.

Detailed Implementation
[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
[0020] like Figures 1 to 7 As shown, a slitting device for chemical fiber paper tubes includes an operating table 1. A back plate 2 is vertically fixed to the rear end of the top of the operating table 1. A top plate 3 is fixed to the top of the back plate 2 facing forward. A first hydraulic cylinder 4 is vertically fixed to one end of the top plate 3. The piston rod of the first hydraulic cylinder 4 faces downward and is fixedly connected to an inverted U-shaped lifting frame 5. A rotating shaft 6 is horizontally and rotatably mounted between the bottom ends of the two vertical parts of the lifting frame 5. A cutting saw blade 7 is coaxially fixedly sleeved on the rotating shaft 6, and a first motor 8 is drivenly connected to one end of the shaft 6. A movable seat 9 is detachably mounted on one side of the operating table 1, and a second hydraulic cylinder 10 is horizontally fixed on the other side of the operating table 1. Cleaning rings 11 are fixedly mounted on the left and right sides of the top of the movable seat 9, and a limiting sleeve 12 is fixedly mounted on the middle part along the left and right direction. The cleaning ring 11 and the limiting sleeve 12 are coaxially arranged, and a cleaning brush 13 is fixedly mounted on the inner ring of the cleaning ring 11, with the bristles 14 of the cleaning brush 13 facing the center of the cleaning ring 11. The piston rod of the second hydraulic cylinder 10 faces the direction of the cutting saw blade 7 and is fixedly connected to the positioning plate 15. The bottom of the positioning plate 15 is slidably connected to the top of the operating table 1. The upper front side of the operating table 1 corresponding to the positioning plate 15 is provided with a scale 16 in the left and right direction.
[0021] When slitting the synthetic fiber paper tube, the piston rod of the second hydraulic cylinder 10 can be extended and retracted to move the positioning plate 15 left and right according to the required length of the synthetic fiber paper tube. This allows for flexible adjustment of the distance between the positioning plate 15 and the cutting saw blade 7. Combined with the scale 16 on the operating table 1, the positioning plate 15 can be quickly adjusted into position. Then, the worker feeds the original synthetic fiber paper tube from the side of the movable seat 9 away from the positioning plate 15, allowing the paper tube to pass through the left cleaning ring 11, the limiting sleeve 12, and the right cleaning ring 11 on the movable seat 9 before abutting against the positioning plate 15. During this process, the bristles 14 of the cleaning brushes 13 on the two cleaning rings 11 can be used for double cleaning of the synthetic fiber paper tube, effectively removing dirt from its surface and preventing adverse effects on subsequent cutting. This ensures better cutting results, while the limiting sleeve 12, which is compatible with the synthetic fiber paper tube, effectively limits its placement. Next, the first hydraulic cylinder 4 is operated, extending its piston rod, which drives the lifting frame 5 and the cutting saw blade 7 to move downwards as a whole. Simultaneously, the first motor 8 is operated, driving the cutting saw blade 7 to rotate, thus coordinating the cutting of the chemical fiber paper tubes. After completion, the cut chemical fiber paper tubes of a fixed length are removed by the operator, and the remaining chemical fiber paper tubes continue to move towards the positioning plate 15 until they re-abut against the positioning plate 15, and then the cutting continues as described above. When the required length of the chemical fiber paper tube changes, the position of the positioning plate 15 can be adjusted again by extending and retracting the piston rod of the second hydraulic cylinder 10. When the required outer diameter of the chemical fiber paper tube changes, the movable seat 9 can be disassembled and replaced entirely through the detachable connection between the movable seat 9 and the operating table 1. In this way, accurate length-limiting placement and double cleaning treatment can be achieved for chemical fiber paper tubes of different outer diameter specifications, which can effectively improve the cutting quality and make the device more practical.
[0022] In this embodiment, a square mounting groove 17 is provided at the bottom of the movable seat 9. Several locking blind holes 18 are provided on the left and right walls of the mounting groove 17. A mounting block 19 is fixed on the top of the operating table 1 corresponding to the mounting groove 17. Movable grooves 20 are provided on both the left and right sides of the mounting block 19. Electric push rods 21 are embedded in the left and right ends of the mounting block 19. The telescopic end of the electric push rod 21 extends into the movable groove 20 on the same side and is fixedly connected to a locking plate 22. Several locking rods 23 arranged in a rectangular array are fixed on the side of the locking plate 22 away from the corresponding electric push rod 21. The movable seat 9 is fitted onto the outside of the mounting block 19 through the mounting groove 17. The locking plate 22 abuts against the groove wall of the mounting groove 17 on the same side. The locking rods 23 correspond one-to-one with the locking blind holes 18 on the same side and are inserted. When the outer diameter of the cut chemical fiber paper tube changes, the machine can be stopped by first running two electric push rods 21 to retract their telescopic ends, causing the locking plate 22 and its locking rod 23 to retract into the corresponding movable slot 20, thus releasing the insertion lock of the movable seat 9. Then, the movable seat 9 can be pulled out, and the original movable seat 9 can be inserted. Next, take the movable seat with the matching cleaning ring 11 and the limiting sleeve 12, align it with the mounting block 19 and install it in place. Then, run two electric push rods 21 to extend their telescopic ends, causing the locking plate 22 to press against the groove wall of the corresponding mounting slot 17, so that the locking rod 23 is inserted into the corresponding locking blind hole 18, locking the movable seat 9 in place. This completes the fixed installation of the new movable seat 9, which is stable and does not affect subsequent use. Therefore, the cleaning ring 11 and the limiting sleeve 12 can be replaced as a whole by flexibly and conveniently disassembling and assembling the movable seat 9. This allows the device to meet the slitting and processing needs of chemical fiber paper tubes with different outer diameters, making it widely applicable, more flexible and convenient to use, and more practical.
[0023] In this embodiment, the mounting block 19 is adapted to the mounting groove 17 to ensure that the movable seat 9 is smoothly installed in place.
[0024] In this embodiment, the locking rod 23 is adapted to the corresponding locking blind hole 18 to ensure that the locking rod 23 is smoothly inserted into place, thereby achieving the insertion and locking of the movable seat 9.
[0025] In this embodiment, an inverted T-shaped slider 24 is fixedly connected to the bottom of the positioning plate 15. An inverted T-shaped groove 25 is provided on the top of the operating table 1 corresponding to the slider 24 along the left and right directions. The slider 24 is slidably disposed on the groove 25 to effectively guide and limit the movement of the positioning plate 15, so as to ensure the smooth adjustment of the distance between the positioning plate 15 and the cutting saw blade 7.
[0026] In this embodiment, a third hydraulic cylinder 26 is horizontally fixed along the left-right direction on the side of the top plate 3 away from the first hydraulic cylinder 4. The piston rod of the third hydraulic cylinder 26 faces away from the first hydraulic cylinder 4 and is fixedly connected to a second motor 27. The output shaft of the second motor 27 faces away from the first hydraulic cylinder 4 and is fixedly connected to a rotating rod 28. A baffle 29 is fixedly connected to the bottom end of the rotating rod 28. This ensures that during the initial feeding, both the rotating rod 28 and the baffle 29 are located above the top plate 3, thus not affecting the insertion and feeding of the original chemical fiber paper tube. After the material is loaded and before cutting, the second hydraulic cylinder 26 can be operated to extend its piston rod, moving the baffle 29 to the tail end of the chemical fiber paper tube. Then, the second motor 27 is operated to rotate the rotating rod 28 and the baffle 29 180 degrees, so that the baffle 29 is flipped downwards and abuts against the tail end of the chemical fiber paper tube, which can further limit the axial movement of the chemical fiber paper tube. When cutting as described above, the axial movement of the chemical fiber paper tube can be effectively avoided, thereby further improving the cutting quality. During subsequent loading, the retraction of the piston rod of the second hydraulic cylinder 26 can also be used to automatically move the baffle 29 and the remaining chemical fiber paper tube towards the positioning plate 15, eliminating the need for manual control of the chemical fiber paper tube movement and loading, saving more effort and making the device more practical.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
