Description

Technical Field

[0001] This invention relates to the field of extrusion traction device technology, specifically to an extrusion traction device based on multiple parallel composite chopped fibers and its usage method. Background Technology

[0002] A composite chopped fiber multi-parallel extrusion traction device is an industrial equipment that can process multiple chopped fibers simultaneously through multiple parallel extrusion and traction units to achieve an efficient and uniform fiber mixing and traction process. This device typically includes multiple traction frames, each equipped with an infeed wheel and an outfeed frame. By precisely controlling the traction angle and force, the arrangement and orientation of the fibers during the extrusion process are ensured, thereby producing composite materials with specific properties and structures.

[0003] The traction device for composite chopped fibers plays an important role in industrial production. It enables the simultaneous processing of multiple chopped fibers through multiple parallel extrusion and traction units. This equipment is designed with multiple traction frames, each equipped with an inlet wheel and an outlet frame.

[0004] The finished composite chopped fibers are in rolls. When the composite chopped fibers are pulled, the position of the fiber exit line is constantly changed on the roll, which will result in uniform traction force for each fiber strip. The inconsistent traction force leads to uneven material properties. Therefore, in order to solve the above problems, an extrusion traction device based on multiple parallel composite chopped fibers and its usage method are proposed. Summary of the Invention

[0016] The method of using a multi-parallel extrusion traction device based on composite chopped fibers

[0017] S1: To achieve traction of the limiting belt while ensuring uniform traction force, the merged fiber filaments are pulled out at a constant speed by the second traction component. The second traction component is fixed to the external support. Simultaneously, the second servo motor is started, driving the second gear to rotate. The second gear drives the outer meshing first gear to rotate. The second gear and the first gear simultaneously drive the internal rotating column to rotate. At this time, the two internal rotating columns rotate in opposite directions. The internal rotating column is connected to the inner side of the inner groove support plate to ensure the stability of the internal rotating column during rotation. The rotation of the internal rotating column drives the rubber cylinder to rotate through the straight spring. At this time, multiple rubber cylinders rotate simultaneously. The fiber filaments pass through two rubber cylinders in the same group. The two rubber cylinders are in close contact with each other. At the same time, the two rubber cylinders undergo a certain deformation when in close contact. The part of the two rubber cylinders in close contact compresses the corresponding straight spring. Under the elastic force of the straight spring, the tightness of the two rubber cylinders can be improved. When the two rubber cylinders rotate, they pull the fiber filaments, and the fiber filaments gradually loosen from the fiber roll. This ensures that the fiber filament between the second traction assembly and the first traction assembly is in a stable moving state. Simultaneously, as the fiber filament moves, the outer side of the fiber filament is in contact with the two shafts, and the springs inside the two shafts are in opposite directions, causing the fiber filament to be tightly pressed against the two shafts. During the movement of the fiber filament, friction causes the shafts to rotate. The shafts are rotatably connected to the inner hole of the fixed solid column via a side rotating port. When the shafts rotate, they cause the springs inside, fixed via a movable column groove, to rotate. A triangular clip fixed on one side of the spring fits against the inner side of the triangular groove opened in the fixed solid column. The rotation of the shafts allows for the storage of force on the springs. When the torque of the springs reaches its limit, the triangular clip disengages from the inside of the triangular groove and fits against the inner side of other triangular grooves. Under the torque of the springs, the springs remain in a rotating state. Therefore, when the fiber filament between the second traction assembly and the force-holding assembly becomes loose, the rotation of the shafts via the springs adjusts the fiber filament.

[0018] S2: To ensure the neatness of the fiber filaments during traction and prevent them from tangling and affecting the quality of the cut fibers, the fiber filaments pass between the two rubber cylinders. Simultaneously, the fiber filaments are positioned between the inner groove support plates and pass through the bottom of the rotating drum. The top of the fiber filaments is in contact with the bottom of the rotating drum, preventing knots between the inner groove support plates. As the fiber filaments move, the rotating drum rotates to the outside of the rotating roller, while S2 rotates to the inside of the shaft block. The fiber filaments pass between the two shaft cylinders, allowing them to converge and controlling the direction of the fiber filaments.

[0019] S3: To achieve rapid fiber filament drawing from the fiber roll, the first electric telescopic rod is activated. This rod moves the connecting plate, lower support column, and rotating block. The rotating block is slidably connected to the inner side of the three-way groove in the inner groove support plate. When the bottom of the rotating block is above the rubber cylinders, the first servo motor drives the connecting shaft to rotate, which in turn drives the lead-in blades to rotate. When the lead-in blades rotate 90 degrees, the second electric telescopic rod is activated. This rod moves the support plate, which is slidably connected to the inner side of the base platform via a slide rail, improving the stability of the support plate and vertical plate during movement. The vertical plate movement drives the connecting shaft and lead-in blades to move. The lead-in blades move from the two cylinders; these blades are sheet-like structures. Simultaneously, the lead-in blades also move from inside the two rubber cylinders. After the lead blade protrudes from the left end of the two rubber cylinders, the fiber filament is placed inside the pay-off channel. The electromagnet is then de-energized, deactivating its magnetic attraction with the magnetic post. Under the elastic force of the two spring extension rods, the toothed clamp moves towards the pay-off channel, squeezing the fiber filament. The toothed clamp, with teeth on one side to increase friction with the fiber filament, secures it inside the pay-off channel. This causes the two rubber cylinders to rotate, gradually moving the fiber filament out of the two rubber cylinders and the two shaft cylinders. When the fiber filament protrudes from the rear end of the shaft cylinder, the magnetic attraction between the electromagnet and the magnetic post causes the magnetic post to move the toothed clamp, which then retracts into the receiving groove, allowing the fiber filament to be removed.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, by setting a first traction component, a second traction component, and a force-holding component, the device realizes the opposite rotation of the two built-in rotating columns, which enhances the stability of the rotation. The built-in rotating columns drive the rubber cylinders to rotate through straight springs. Multiple rubber cylinders rotate simultaneously, which improves the traction efficiency of the fiber filaments. At the same time, the deformation of the rubber cylinders and the elastic force of the straight springs enhance the tightness and friction between the rubber cylinders, effectively controlling the traction force of the fiber filaments and preventing the unevenness of material properties caused by inconsistent traction forces. In addition, the interaction of the shaft cylinder, the spring, the triangular retaining strip, and the fixed solid column realizes the fine adjustment of the traction force of the fiber filaments, ensuring the constant traction force and further improving the uniformity of material properties.

[0022] 2. In this invention, the arrangement of fiber filaments, rubber cylinders, inner groove support plates, shaft cylinders, and rotating drums effectively ensures the neatness of the fiber filaments during the traction process, preventing them from tangling and thus avoiding affecting the quality of the chopped fibers. The fiber filaments pass between the two rubber cylinders and are simultaneously positioned between the inner groove support plates. The design of the inner groove support plates prevents the fiber filaments within a single production line from shifting. The guiding function and anti-knotting function of the rotating drum, as well as the control of the fiber filaments between the inner groove support plates, further improve production quality. In addition, the synergistic effect of the rotating drum, rotating rollers, shaft block, and 2 precisely controls the direction of the fiber filaments, preventing a decline in production quality due to unevenness and ensuring a smooth and efficient traction process.

[0023] 3. In this invention, the first electric telescopic rod, support plate, connecting rod, lead wire blade and side tooth clamp, the magnetic attraction of the electromagnet and magnetic column, and the tooth design of the side tooth clamp enhance the friction between the fiber filaments, ensuring the stable fixation of the fiber filaments and the lead wire. By controlling the power off and the magnetic attraction, the fiber filaments can be quickly removed, improving the lead wire efficiency, reducing the difficulty of operation, and thus improving the short cutting efficiency.

[0050] Workflow: The limiting belt is pulled while maintaining uniform traction. The merged fiber filaments 1 are pulled out at a constant speed by the second traction component 8, which is fixed to the external support. Simultaneously, the second servo motor 56 is activated, driving the second gear 55 to rotate. The second gear 55 then drives the outer meshing first gear 54 to rotate. Both the second gear 55 and the first gear 54 simultaneously drive the internal rotating column 53 to rotate. At this time, the two internal rotating columns 53 rotate in opposite directions. The internal rotating columns 53 are rotatably connected to the inner side of the inner groove support plate 22, ensuring stability during rotation. The rotation of the internal rotating columns 53 is driven by a straight spring 52. When the rubber cylinder 51 rotates, multiple rubber cylinders 51 rotate simultaneously. The fiber filament 1 passes through two rubber cylinders 51 in the same group, with the two rubber cylinders 51 pressed tightly against each other. Simultaneously, the two rubber cylinders 51 deform slightly during this pressing motion. The pressed parts of the two rubber cylinders 51 compress the corresponding straight springs 52. Under the elastic force of the straight springs 52, the tightness of the contact between the two rubber cylinders 51 and the fiber filament 1 is increased. This also increases the friction between the two rubber cylinders 51 and the fiber filament 1. As the two rubber cylinders 51 rotate, they pull on the fiber filament 1, causing it to gradually loosen from the fiber roll 3. The first traction assembly 5 provides initial traction for the fiber filament 1. The effect is that the fiber filament 1 at the end between the second traction component 8 and the first traction component 5 can be kept in a stable moving state. At the same time, when the fiber filament 1 moves, the outer side of the fiber filament 1 is in close contact with the two shaft cylinders 61, and the springs 63 inside the two shaft cylinders 61 are in opposite directions. The fiber filament 1 is in close contact with the two shaft cylinders 61. When the fiber filament 1 moves, it will drive the shaft cylinder 61 to rotate under the action of friction. The shaft cylinder 61 is rotatably connected to the inner hole rotating ring 66 fixed to the fixed solid column 67 through the side rotating port 65. When the shaft cylinder 61 rotates, it drives the spring 63 fixed to the inner side through the movable column groove 62 to rotate. The triangular retaining bar fixed on one side of the spring 63 The triangular clip 64 fits against the inner side of the triangular slot 68 opened in the fixed solid column 67. When the shaft cylinder 61 rotates, it can store the force of the spring 63. When the torque of the spring 63 reaches its limit, the triangular clip 64 disengages from the inside of the triangular slot 68. The triangular clip 64 fits against the inner side of the other triangular slots 68. Under the action of the torque of the spring 63, the spring 63 can be kept in a rotating state. Thus, when the fiber filament 1 between the second traction component 8 and the force holding component 6 becomes loose, the rotation of the shaft cylinder 61 driven by the spring 63 can adjust the fiber filament 1, thereby controlling the traction force on the fiber filament 1 to remain unchanged and ensuring the uniformity of material properties.

[0051] To ensure the neatness of fiber filaments 1 during traction and prevent them from tangling and affecting the quality of the cut fibers, fiber filaments 1 pass between two rubber cylinders 51, while simultaneously positioned between inner groove support plates 22. The inner groove support plates 22 prevent the fiber filaments 1 from shifting within a single production line. Simultaneously, fiber filaments 1 pass through the bottom end of rotating drum 29, with the top end of fiber filaments 1 fitting against the bottom end of rotating drum 29. Rotating drum 29 guides the fiber filaments 1 and prevents them from knotting between the inner groove support plates 22. As fiber filaments 1 move, rotating drum 29 rotates outside the rotating roller 28 and inside the shaft rotating block 26. Fiber filaments 1 pass between two shaft cylinders 61, allowing them to converge and control their direction, preventing production quality degradation due to uneven fiber filaments.

[0052] When quickly drawing the fiber filaments 1 from the fiber roll 3, the first electric telescopic rod 24 is activated. The first electric telescopic rod 24 drives the connecting plate 25, the lower support column 27, and the shaft rotating block 26 to move. The shaft rotating block 26 is slidably connected to the inside of the three-sided sliding groove 23 opened in the inner groove support plate 22, which improves the stability of the shaft rotating block 26, the lower support column 27, and the connecting plate 25 when they move. When the bottom end of the shaft rotating block 26 is in the upper part between the rubber cylinders 51, the first servo motor 43 is activated. The first servo motor 43 drives the connecting shaft rod 71 to rotate, and the connecting shaft rod 71 drives the fiber filaments 1 to move. The lead wire blade 72 rotates. When the lead wire blade 72 rotates 90 degrees, the second electric telescopic rod 46 is activated. The second electric telescopic rod 46 drives the support plate 44 to move. The support plate 44 is slidably connected to the inner side of the base 21 via the slide rail 45, improving the stability of the support plate 44 and the vertical plate 41 during movement. The movement of the vertical plate 41 drives the connecting rod 71 and the lead wire blade 72 to move. The lead wire blade 72 moves from the two shaft cylinders 61. The lead wire blade 72 has a plate-like structure. At the same time, the lead wire blade 72 also moves from inside the two rubber cylinders 51. When the lead wire blade 72 rotates 90 degrees, the second electric telescopic rod 46 is activated. The second electric telescopic rod 46 drives the support plate 44 to move. The support plate 44 is slidably connected to the inner side of the base 21 via the slide rail 45, improving the stability of the support plate 44 and the vertical plate 41 during movement. The vertical plate 41 moves, driving the connecting rod 71 and the lead wire blade 72 to move. The lead wire blade 72 moves from the two shaft cylinders 61. The lead wire blade 72 has a plate-like structure. At the same time, the lead wire blade 72 moves from the two rubber cylinders 51. When the lead wire blade 72 rotates 90 degrees, the second electric telescopic rod 46 is activated. The second electric telescopic rod 46 drives the connecting rod 72 to move ...72 drives the connecting rod 72 to move. The 2. After the left ends of the two rubber cylinders 51 protrude, the fiber filament 1 is placed inside the feeding channel 73. The electromagnet 75 is de-energized, and the electromagnet 75 and the magnetic column 77 are no longer magnetically attracted. Under the elastic force of the two spring telescopic rods 76, the toothed clamp 78 moves closer to the feeding channel 73, squeezing the fiber filament 1. The toothed clamp 78 has teeth on one side to increase the friction between it and the fiber filament 1. At this time, the fiber filament 1 is fixed inside the feeding channel 73. The second servo motor 56 is activated to rotate the two rubber cylinders 51. At this time, the fiber filament 1 gradually moves out of the two rubber cylinders 51 and the two shaft cylinders 61. When the fiber filament 1 protrudes from the rear end of the shaft cylinder 61, the electromagnet 75 is activated. Under the magnetic attraction between the electromagnet 75 and the magnetic column 77, the magnetic column 77 drives the side tooth clamp 78 to move. The side tooth clamp 78 is stored in the storage groove 74, so that the fiber filament 1 can be taken out, improving the wire leading efficiency of the fiber filament 1, reducing the difficulty of operation, and thus improving the short cutting efficiency of the fiber filament 1.
