Technical Field
[0001] This utility model belongs to the field of chemical fiber paper tube processing technology, specifically relating to an integrated forming device for chemical fiber paper tube wire groove and hook point. Background Technology
[0002] In existing chemical fiber equipment, chemical fiber paper tubes are used to wind coarse denier chemical fiber filaments such as industrial yarns. Common chemical fiber paper tubes typically have a circular groove cut into them to allow the filament ends to be inserted and secured. To further facilitate this insertion and fixation, several beveled cuts are made into the groove to create hook points for quick and secure filament attachment. However, in the actual processing of chemical fiber paper tubes, the groove and hook points often need to be sequentially cut and stamped, making it impossible to process them simultaneously. This results in low overall processing efficiency and needs improvement. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide an integrated forming device for the fiber tube filament groove and the hook point, which can realize the rolling forming process of the filament groove and the hook point in one step, so as to solve the above problems.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an integrated forming device for chemical fiber paper tube filament channels and hook points, comprising a conveying mechanism and a plurality of bearing seats fixedly mounted on the conveying mechanism and spaced apart along the conveying direction of the conveying mechanism. An arc-shaped placement groove is provided on the top of each bearing seat. A first L-shaped support is fixedly mounted on the front side of the conveying mechanism. A first hydraulic cylinder is fixedly mounted on the horizontal portion of the first L-shaped support. The piston rod of the first hydraulic cylinder faces rearward and is rotatably connected to a limiting plate. A first conical block is coaxially fixed on the rear side of the limiting plate, with the small-diameter end of the first conical block facing rearward. The vertical direction of the first L-shaped support corresponding to the limiting plate... A through groove is provided on part of the first L-shaped support. A second L-shaped support is fixedly provided on the rear side of the conveying mechanism corresponding to the first L-shaped support. A rack is slidably provided on the horizontal part of the second L-shaped support in the left-right direction. A wire groove cutter is detachably connected to the front side of the rack in the left-right direction. Several wire hook cutters are fixedly provided on the front side of the wire groove cutter in the left-right direction. A rotating shaft is provided through and rotatably on the vertical part of the second L-shaped support in the front-back direction. A motor is driven to the rear end of the rotating shaft, and a gear is coaxially fixedly connected to the front end. The gear meshes with the rack, and a second cone is coaxially fixed on its front side. The small diameter end of the second cone faces forward.
[0005] Preferably, a second hydraulic cylinder is fixedly mounted on the bottom front side of the rack. The piston rod of the second hydraulic cylinder faces upward and is fixedly connected to a lifting plate. A plurality of insert rods arranged in a rectangular array are fixedly mounted on the top of the lifting plate. A movable groove is opened on the bottom of the rack corresponding to the lifting plate. A slot is opened on the front side of the rack above the movable groove. A through hole communicating with the slot is opened on the top of the movable groove corresponding to the insert rod. A blind hole is opened on the top of the slot corresponding to the through hole. An insert plate is fixedly mounted on the rear side of the wire groove cutter. The insert plate is inserted into the slot, and a locking hole is opened through the corresponding position of the insert rod. The lifting plate abuts against the top of the movable groove. The insert rod passes through the corresponding through hole and locking hole and is inserted into the corresponding blind hole.
[0006] Preferably, the insert plate is adapted to the slot, and the insert rod is adapted to the corresponding through hole, locking hole and blind hole.
[0007] Preferably, the limiting plate is adapted to the corresponding through slot.
[0008] Preferably, the outer side of the first cone block is covered with a rubber anti-slip pad.
[0009] Preferably, the placement groove is provided with a wear-resistant ceramic coating.
[0010] Preferably, the bottom of the rack is fixedly connected to an inverted T-shaped slider, and the top of the horizontal part of the second L-shaped support corresponding to the slider is provided with an inverted T-shaped groove adapted to the slider, and the slider is slidably disposed in the groove.
[0011] Preferably, an inverted L-shaped support rod is fixedly connected to the top of the vertical portion of the second L-shaped support, and the horizontal portion of the support rod faces forward and its tail end is equipped with a photoelectric sensor facing the conveying mechanism.
[0012] The beneficial effects of this utility model are as follows: During use, the conveying mechanism drives the carrier seat containing the chemical fiber paper tube to move in a stepwise manner. When it reaches the space between the first and second cone blocks, the first hydraulic cylinder is activated, its piston rod extends, and it drives the limiting plate and the first cone block to move backward. After passing through the through groove, the first cone block is inserted into the chemical fiber paper tube until the limiting plate presses against the front end of the chemical fiber paper tube. Then, it drives the chemical fiber paper tube to move backward synchronously until it presses against the gear, so that the second cone block is also inserted into the chemical fiber paper tube. Then, the motor is activated, and the rotating shaft drives the gear to rotate. The rotation of the gear can drive the chemical fiber paper tube and the limiting plate to rotate as a whole, and can also drive the rack meshing with the gear to move. Thus, the moving wire groove cutter and the hook point cutter cooperate with the rotating chemical fiber paper tube to roll and form a ring of wire grooves and several hook points connected to the wire grooves in one go at the corresponding positions of the chemical fiber paper tube. Next, the first hydraulic cylinder actuates again, its piston rod retracts, driving the limiting plate and the synthetic fiber paper tube forward as a whole. This first separates the synthetic fiber paper tube from the second cone block. Then, after the limiting plate moves forward through the slot, the vertical part of the first L-shaped support further separates the synthetic fiber paper tube from the first cone block, allowing it to return to the support seat. Afterward, the motor reverses, driving the rack to retract and return to its original position. The conveying mechanism then drives the synthetic fiber paper tube to continue its step-by-step forward conveying. This allows for a one-time roll forming process of the grooves and hooks on the synthetic fiber paper tube, resulting in higher overall efficiency and greater practicality. Furthermore, the detachable design between the groove cutter and the rack facilitates flexible disassembly and replacement of the groove cutter and hook cutter when damaged, making overall use more flexible and convenient.

Detailed Implementation
[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
[0024] like Figures 1 to 9 As shown, an integrated forming device for chemical fiber paper tube filament channels and hook points includes a conveying mechanism 1 and several bearing seats 2 fixedly mounted on the conveying mechanism 1 and spaced apart along the conveying direction of the conveying mechanism 1. An arc-shaped placement groove 3 is provided on the top of the bearing seat 2. A first L-shaped support 4 is fixedly mounted on the front side of the conveying mechanism 1. A first hydraulic cylinder 5 is fixedly mounted on the horizontal part of the first L-shaped support 4. The piston rod of the first hydraulic cylinder 5 faces backward and is rotatably connected to a limiting plate 6. A first cone block 7 is coaxially fixed on the rear side of the limiting plate 6. The small diameter end of the first cone block 7 faces backward. A through groove 8 is provided on the vertical part of the first L-shaped support 4 corresponding to the limiting plate 6. A second L-shaped support 9 is fixedly mounted on the rear side of the conveying mechanism 1 corresponding to the first L-shaped support 4. A rack 10 is slidably mounted on the horizontal part of the second L-shaped support 9 in the left-right direction. A wire groove cutter 11 arranged in the left-right direction is detachably connected to the front side of the rack 10. Several wire hook cutters 12 distributed at intervals in the left-right direction are fixedly mounted on the front side of the wire groove cutter 11. A rotating shaft 13 is rotatably mounted through the vertical part of the second L-shaped support 9 in the front-back direction. A motor 14 is driven to the rear end of the rotating shaft 13, and a gear 15 is coaxially fixedly connected to the front end. The gear 15 meshes with the rack 10, and a second cone block 16 is coaxially fixed to its front side, with the small diameter end of the second cone block 16 facing forward.
[0025] In use, the conveying mechanism 1 drives the carrier 2, which holds the chemical fiber paper tube, to move in a stepwise manner. When it reaches between the first cone 7 and the second cone 16, the first hydraulic cylinder 5 is activated, and its piston rod extends, driving the limiting plate 6 and the first cone 7 to move backward. After passing through the through groove 8, the first cone 7 is inserted into the chemical fiber paper tube until the limiting plate 6 presses against the front end of the chemical fiber paper tube. Then, the chemical fiber paper tube moves backward synchronously until it presses against the gear 15, causing the second cone 16 to also be inserted into the chemical fiber paper tube. Then, the motor 14 is activated, driving the gear 15 to rotate through the rotating shaft 13. The rotation of the gear 15 can drive the chemical fiber paper tube and the limiting plate 6 to rotate as a whole, and can also drive the rack 10 meshing with the gear 15 to move. Thus, the moving wire groove cutter 11 and the hook point cutter 12 cooperate with the rotating chemical fiber paper tube to roll and form a ring of wire grooves and several hook points connected to the wire grooves in one go at the corresponding positions of the chemical fiber paper tube. Next, the first hydraulic cylinder 5 actuates again, its piston rod retracts, driving the limiting plate 6 and the chemical fiber paper tube forward as a whole. This first separates the chemical fiber paper tube from the second cone block 16. Then, after the limiting plate 6 moves forward through the through groove 8, the chemical fiber paper tube continues to separate from the first cone block 7 under the obstruction of the vertical part of the first L-shaped support 4, thus allowing the chemical fiber paper tube to return to the bearing seat 2. Afterward, the motor 14 reverses, driving the rack 10 to retract to its original position, and the conveying mechanism 1 drives the chemical fiber paper tube to continue its step-by-step forward conveying. In this way, the wire grooves and hook points on the chemical fiber paper tube can be rolled and formed in one go, resulting in higher overall efficiency and greater practicality. In addition, the detachable connection between the wire groove cutter 11 and the rack 10 facilitates flexible disassembly and replacement when the wire groove cutter 11 and the hook point cutter 12 are damaged, making the overall use more flexible and convenient. The conveying mechanism 1 can use existing conventional belt or chain conveying equipment. Both the wire groove cutter 11 and the wire hook point cutter 12 can be made using existing technologies.
[0026] In this embodiment, a second hydraulic cylinder 17 is fixedly mounted on the bottom front side of the rack 10. The piston rod of the second hydraulic cylinder 17 faces upward and is fixedly connected to a lifting plate 18. A plurality of insert rods 19 arranged in a rectangular array are fixedly mounted on the top of the lifting plate 18. A movable groove 20 is opened on the bottom of the rack 10 corresponding to the lifting plate 18. A slot 21 is opened on the front side of the rack 10 above the movable groove 20. A through hole 22 communicating with the slot 21 is opened on the top of the movable groove 20 corresponding to the insert rod 19. A blind hole 23 is opened on the top of the slot 21 corresponding to the through hole 22. An insert plate 24 is fixedly mounted on the rear side of the wire groove cutter 11. The insert plate 24 is inserted into the slot 21, and a locking hole 25 is opened through the corresponding position of the insert rod 19. The lifting plate 18 abuts against the top of the movable groove 20. The insert rod 19 passes through the corresponding through hole 22 and locking hole 25 and is inserted into the corresponding blind hole 23. When the cutter needs to be replaced, the second hydraulic cylinder 17 can be operated while the machine is stopped, causing its piston rod to retract and the lifting plate 18 to move downwards until the insertion rod 19 is disengaged from the through hole 22. This releases the locking of the insertion plate 24, allowing the original wire groove cutter 11 and hook point cutter 12 to be completely removed. Next, take the new cutter, align its insertion plate 24 with the slot 21, and insert it into place. Then, operate the second hydraulic cylinder 17, extending its piston rod and causing the lifting plate 18 to move upwards and press against the top of the movable slot 20. This allows the insertion rod 19 to pass through the corresponding through hole 22 and locking hole 25 and be inserted into the corresponding blind hole 23, locking the insertion plate 24 in place. This completes the secure installation of the new cutter, ensuring a stable installation without affecting subsequent use. This allows for flexible and convenient disassembly and assembly of the cutter, facilitating easy replacement when the cutter is damaged, making the overall device more flexible, convenient, and practical.
[0027] In this embodiment, the insert plate 24 is adapted to the slot 21, and the insert rod 19 is adapted to the corresponding through hole 22, locking hole 25 and blind hole 23 to ensure smooth insertion, positioning and locking of the insert plate 24.
[0028] In this embodiment, the limiting plate 6 is adapted to the corresponding through groove 8 to ensure that the limiting plate 6 can pass smoothly through the through groove 8. The diameter of the limiting plate 6 is smaller than the outer diameter of the chemical fiber paper tube, so that when the limiting plate 6 moves forward through the through groove 8 after rolling, the vertical part of the first L-shaped support 4 can block the chemical fiber paper tube, thereby separating the chemical fiber paper tube from the first cone block 7, without affecting the conveying mechanism 1 to drive the conveying of the chemical fiber paper tube.
[0029] In this embodiment, the outer side of the first cone 7 is covered with a rubber anti-slip pad 26, which can form an interference fit between the first cone 7 and the chemical fiber paper tube after the first cone 7 is inserted into the chemical fiber paper tube. This facilitates the overall rotation of the chemical fiber paper tube, the first cone 7 and the limiting plate 6 during rolling. It also facilitates the smooth movement of the limiting plate 6 with the chemical fiber paper tube and its separation from the second cone 16 after rolling by the contraction of the piston rod of the first hydraulic cylinder 5.
[0030] In this embodiment, the placement groove 3 is provided with a wear-resistant ceramic coating (not shown in the figure) to improve the wear resistance and smoothness of the placement groove, and to ensure the smooth back-and-forth movement of the chemical fiber paper tube during the rolling process.
[0031] In this embodiment, an inverted T-shaped slider 27 is fixedly connected to the bottom of the rack 10. An inverted T-shaped groove 28 adapted to the slider is provided on the top of the horizontal part of the second L-shaped support 9 corresponding to the slider 27. The slider 27 is slidably disposed in the groove 28 to effectively guide and limit the movement of the rack 10.
[0032] In this embodiment, an inverted L-shaped support rod 29 is fixedly connected to the top of the vertical part of the second L-shaped support 9. The horizontal part of the support rod 29 faces forward and its tail end is equipped with a photoelectric sensor 30 facing the conveying mechanism 1. Existing technology can be used to make the photoelectric sensor 30 electrically connected to the control center of the whole machine (not shown in the figure, existing technology can be used) during the rolling process, so as to detect whether the chemical fiber paper tube has reached the rolling station, which is convenient to cooperate with the continuous automation of the rolling operation.
[0033] 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.
