DETAILED DESCRIPTION

[0018] The following embodiments are further described in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] The terms "top surface", "bottom surface" and "underside" are based on the normal use state of the carbon fiber tow winder and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0020] A carbon fiber tow collecting machine, such as Figure 1 As shown, it includes a body 101 and a turntable 102 rotatably arranged on the body 101, two screw pressing rods 104 and two winding rollers 103 are provided on the turntable 102, and the two winding rollers 103 are respectively located at the winding station and the unloading station of the turntable 102. A hollow sliding platform 2 is provided on the body 101 for sliding along the axial direction of the winding roller 103. Along the advancing direction of the tow, the sliding platform 2 is located in front of the unloading station and is arranged adjacent to the unloading station; like Figure 2 As shown, the side of the sliding table 2 adjacent to the turntable 102 is a wire guide surface 204, and the wire guide surface 204 is provided with a wire pressing roller 4 for pressing the wire bundle on the wire guide surface 204. Along the advancing direction of the wire bundle, the wire guide surface 204 is also sequentially provided with a tape groove 202 and a shear groove 201, and both the tape groove 202 and the shear groove 201 extend perpendicular to the advancing direction of the wire bundle; Specifically, the wire pressing roller 4 is arranged parallel to the extension direction of the tape groove 202, and there are two wire pressing rollers 4. Both wire pressing rollers 4 are provided with hub motors for controlling the two wire pressing rollers 4 to rotate independently. Two third guide sleeves 209 are fixedly connected to the wire guide surface 204. A third guide rod 401 is slidably fitted inside the third guide sleeve 209. One end of the third guide rod 401 is connected to the wire pressing roller 4 through a bearing. A third cylinder 402 is provided inside the sliding table 2. The movable end of the third cylinder 402 is connected to the two third guide rods. The other ends of 401 are fixedly connected, and the two wire pressing rollers 4 are driven by the third cylinder 402 to move in a direction perpendicular to the plane where the wire guide surface 204 is located; among the two wire pressing rollers 4, one is arranged close to the tape groove 202, and the other is arranged close to the winding roller 103 located on the unloading station. Through the rotation of the two wire pressing rollers 4, the wire bundle can be transported and the wire bundle between the two wire pressing rollers 4 can be tensioned. A release layer needs to be provided on the wire pressing roller 4 to prevent the tape from adhering to the wire pressing roller 4 and being difficult to separate.

[0021] like Figure 12 and 13 As shown, the interior of the sliding table 2 is provided with a tape output mechanism connected to the tape groove 202, and the inner side of the tape groove 202 is provided with a tape cutter 6; like Figure 6As shown, a first shearing knife 211 is provided on the inner side of the shearing groove 201 parallel to its extension direction, and a second shearing knife 502 is provided on the sliding table 2 to slide relative to the first shearing knife 211. The first shearing knife 211 and the second shearing knife 502 cooperate with each other to cut the wire bundle.

[0022] The above-mentioned wire drawing machine can be used for winding carbon fiber tows, wherein the two winding rollers 103 can be switched to realize the continuous winding operation of the wire drawing machine. Two first guide rods 301 are fixedly connected to the machine body 101 along the axial direction parallel to the winding roller 103, and the back of the sliding table 2 is fixedly connected to the first guide sleeve 205 that slides with the first guide rod 301, and a second cylinder 302 is also provided on the machine base 101. The movable end of the second cylinder 302 is fixedly connected to the sliding table 2, so that the sliding table 2 can be pushed to slide along the first guide rod 301 by the second cylinder 301.

[0023] When the wire-winding machine is in use, the winding roller 103 that is fully wound with the wire bundle is first switched to the unloading station. At this time, the wire bundle connected between the two winding rollers 103 is supported by the wire pressing rod 104; then the second shearing knife 502 and the wire pressing roller 4 move away from the wire guide surface 204, leaving a gap for the wire bundle to enter between the second shearing knife 502 and the wire pressing roller 4 and the wire guide surface 204; the sliding table 2 is driven to move close to the machine body 101, so that the wire pressing roller 4 hooks the wire bundle between the winding roller 103 and the wire pressing rod 104, and then the wire pressing roller 4 moves close to the wire guide surface 204 to press the wire bundle tightly on the wire guide surface 204; at this time, the wire bundle is cut by the blade on the turntable 102, and the winding roller 103 and the wire pressing roller 4 located at the unloading station rotate at the same time, and the cut end of the wire bundle is wound onto the winding roller 10 3; at the same time, the tape conveying mechanism unwinds the tape and sends it out from the tape groove 202, so that the tape adheres to the side of the tow adjacent to the guide wire surface 204. When the set length of tape is adhered, the tape is cut by the tape cutter 6; then the tape and the tow are cut at the same time by the first shearing knife 211 and the second shearing knife 502, and the cut part of the tape and the tow fall together to achieve the trimming operation of the tow end, and the tape remaining on the tow continues to be reeled as the tow, and finally the tape adheres to the tow roll, so as to fix the tow end and prevent the outer layer of the tow roll from loosening. A back pressure roller can also be provided at the position of the machine body 101 close to the unloading station. By pressing the reeling roller with the back pressure roller, the tow and tape can be pressed, further reducing the chance of the tow loosening.

[0024] Compared with the existing wire collecting machine, the wire collecting machine can automatically adhere tape to the wire bundle, and use the tape to stick and fix the end of the wire bundle to the wire bundle roll to prevent the wire bundle roll from loosening, thereby improving the winding effect of the wire collecting machine; the automatic sticking of tape can eliminate the subsequent steps of manually tightening the end of the wire bundle and sticking the tape, thereby improving the automation level and winding efficiency of the equipment; and the first shearing knife 211 and the second shearing knife 502 can also cut the wire bundle and the tape at the same time to realize the trimming operation of the wire bundle end, thereby eliminating the subsequent steps of manually trimming the wire bundle, thereby further improving the automation level and winding efficiency of the equipment; and when trimming the end of the wire bundle, the cut wire bundle is adhered with tape, and the wire bundle is stuck with tape, which can reduce the floating phenomenon of the monofilaments in the carbon fiber bundle, thereby maintaining the cleanliness of the equipment and improving the practicality of the wire collecting machine.

[0025] Further improvements are, Figure 7 、 9 As shown in Figure 11, the tape output mechanism includes a tape holder 210, which is fixed to the side of the tape groove 202 adjacent to the shear groove 201. The tape holder 210 is detachably connected to a reel 213 for sleeved tape. The tape holder 210 has a guide surface that fits the smooth surface of the tape, and the guide surface and the guide wire surface 204 are smoothly transitioned through an arc surface. A push plate 9 is provided on the tape holder 210 facing the guide surface, and the push plate 9 is slidingly arranged relative to the guide surface and can slide back and forth along the conveying direction of the tape. A release layer is provided on the push plate 9.

[0026] Specifically, in the above-mentioned wire taking-up machine, the tape holder 210 includes two side plates, and the inner sides of the two side plates are provided with slots 212, so that the ends of the unwinding shaft 213 can be inserted into the two slots 212 respectively. When it is necessary to remove the unwinding roller 213, it can be directly taken out from the slots 212, thereby realizing the disassembly and assembly of the winding roller 213, thereby facilitating the replacement of the tape roll mounted on the winding roller 213; the outer sides of the two side plates are parallel to the tape guide surface and are provided with a first guide rail 215, and the first guide rail 215 is provided with a first sliding seat 904, and the first sliding seat 904 is provided with a motor and a rotating wheel fixedly connected to the driving shaft of the motor, and the rotating wheel is rollingly connected to the first guide rail 215, To drive the first sliding seat 904 to move along the first guide rail 215; the first sliding seat 905 is fixedly connected to a sixth guide rod 903 arranged perpendicular to the guide belt surface, and a support rod 901 is fixedly connected between the two sixth guide rods 903, and the support rod 901 is located on the side of the pushing plate 9 away from the guide belt surface, and the pushing plate 9 slides with the sixth guide rod 903, and the support rod 901 and the pushing plate 9 are respectively provided with an electromagnet 902 and a permanent magnet; when the first sliding seat 904 moves along the first guide roller 215, the pushing plate 9 can be driven to slide back and forth along the conveying direction of the tape, and the pushing plate 9 can be driven to slide relative to the guide belt surface through the mutual attraction and repulsion between the electromagnet 902 and the permanent magnet.

[0027] During use, the smooth surface of the unwound tape is sent to the tape groove 202 along the guide surface. When the tape needs to be conveyed, the adhesive surface of the tape is first pressed by the pushing plate 9, and then the tape is pulled to the outside of the tape groove 202 to connect the tape with the tow in the conveying process. Since the tow is in a tensioned state, the tape can be firmly adhered to the tow under the mutual squeezing effect between the tow and the guide surface 204. Then the pushing plate 9 moves away from the guide surface. At this time, the adhesive force between the tape and the tow pulls the tape from the pushing plate 9 is pulled off and the tape is continuously conveyed as the yarn bundle moves; when the tape output length reaches the set length, the push plate 9 moves close to the wire guide surface and presses the tape, stopping the conveying of the tape. The conveying length of the tape can be determined by monitoring the number of rotations of the wire pressing roller 4, and then the tape is cut by the tape cutter 6. At the same time, the push plate 9 pulls the end of the tape to move inside the tape groove 202 to retract the tape. The above operations can realize automatic attachment of the tape to the yarn bundle, thereby improving the degree of automation of the wire collecting machine.

[0028] Further improvements are, Figure 13-14 As shown, the tape cutter 6 is arranged on the arc surface and is arranged parallel to the extension direction of the tape groove 202. The tape cutter 6 has a serrated blade; a knife groove 214 connected to the inner side of the sliding table 2 is opened on the arc surface, and the tape cutter 6 is detachably arranged on the inner side of the knife groove 214, and the blade of the tape cutter 6 protrudes from the arc surface. Side guards 601 are slidingly provided on both sides of the tape cutter 6 along the depth direction of the knife groove 214, and the side guards 601 are connected to the back of the tape cutter 6 through a second elastic member.

[0029] Specifically, in the above-mentioned wire collecting machine, the back of the tape cutter 6 is fixedly connected to the tape cutter holder 603, and the tape cutter holder 603 is fixedly connected to the sliding platform 2 by screws, which can facilitate the replacement and maintenance of the tape cutter 6; the serrated blade of the tape cutter 6 can improve the cutting effect of the tape cutter 6 on the tape; a fifth guide sleeve 604 is provided on the tape cutter holder 603, and a fifth guide rod 605 that slides with the fifth guide sleeve 604 is fixedly connected to the side guard plate 601, and the end of the fifth guide rod 605 is threadedly connected to a limiting nut, and the cooperation of the two can achieve a guiding effect on the side guard plate 601, and a spring piece 602 is provided between the side guard plate 601 and the tape cutter holder 603. Under normal circumstances, the blade of the tape cutter 6 is surrounded by the side guard plate 601.

[0030] During the process of conveying the tape, the push plate 9 is separated from the tape, and the tension of the tape is relatively small. At this time, the smooth surface of the tape is slidably connected to the side guard plate 601, so that the tape can be conveyed normally; when the tape is conveyed, the push plate 9 presses the tape tightly. At this time, under the pulling action of the yarn bundle, the tension of the tape is increased, thereby pressing the side guard plate 601 into the inside of the knife groove 214, exposing the blade of the tape cutter 6, and cutting the tape; after the tape is cut, the pressure of the side guard plate 601 disappears, and under the action of the elastic force of the shrapnel 602, the side guard plate 601 is reset and covers the blade of the tape cutter 6 again, so that the automatic cutting function of the tape can be realized, thereby improving the degree of automation of the wire collecting machine.

[0031] Further improvements are, Figure 3 and 4 As shown, the second shearing knife 502 is fixedly connected to the shearing knife seat 501, and the end of the shearing knife seat 501 away from the body 101 is connected to the sliding table 2 through the first power member. The distance between the blade of the second shearing knife 502 and the guide wire surface 204 gradually decreases from the end adjacent to the body 101 to the end away from the body 101; Figure 5 As shown, a second guide rod 503 arranged perpendicular to the guide wire surface 204 is fixedly connected to the shearing knife seat 501, and a first cylinder 208 and a second guide sleeve 206 slidingly matched with the second guide rod 503 are fixedly connected to the sliding table 2; the second guide sleeve 206 cooperates with the second guide rod 503 to support and guide the shearing knife seat 501 to improve its stability, and the first cylinder 208 provides power to drive the second shearing knife 502 to move to cooperate with the first shearing knife 211 to shear the wire bundle and the tape, and the shearing method can make the cut of the wire bundle smoother; the second shearing knife 502 has an inclined blade, and the length of the second shearing knife 502 sheared along the width direction of the tape can be indirectly controlled by controlling the distance the second shearing knife 502 moves. In order to improve the control accuracy, a distance sensor can be provided on the shearing knife seat 501 to detect the displacement of the second shearing knife 502.

[0032] Further improvements are, Figure 7-9 As shown, the wire guide surface 204 is provided with an air jet 8 that passes through the side wall of the sliding table 2. The angle between the direction of the air jet 8 and the wire guide surface 204 is an acute angle. The air outlet end of the air jet 8 is set toward the filament bundle, and an air pump 801 connected to the air jet 8 is set inside the sliding table 2.

[0033] In this wire collecting machine, in order to prevent the monofilaments at the end of the cut wire bundle from scattering, first a break is cut in the middle of the tape by the second shearing knife 502, and then an air flow is provided by the air pump 801 to make the air flow ejected from the air jet 8, and the ejected air flow flips one side of the second half of the tape to the top of the wire bundle, and then the tape is pressed to wrap the four sides of the end of the wire bundle, and then the section of the wire bundle wrapped with the tape is cut, so that the cut wire bundle can be wrapped by the tape to prevent the monofilaments of the wire bundle from floating around, so as to maintain the cleanliness of the wire collecting machine.

[0034] Further improvements are, Figure 3 As shown, a pressure plate 504 is provided on both sides of the second shearing blade 502. The pressure plate 504 is connected to the shearing blade holder 501 via a first elastic member, and a release layer is provided on the pressure plate 504. Specifically, a fourth guide sleeve 507 is fixedly connected to the shearing blade holder 501, and a fourth guide rod 506 is fixedly connected to the pressure plate 504. The fourth guide rod 506 and the fourth guide sleeve 507 are slidably engaged. A nut 508 is threadedly connected to the end of the fourth guide rod 506 facing away from the pressure plate 504. A spring 505 is provided between the pressure plate 504 and the shearing blade holder 501. The elastically connected pressure plate 504 can compress the flipped portion of the tape during the downward pressure of the second shearing blade 502, so that the tape tightly wraps the tow, thereby preventing the tow from scattering after being cut, thereby maintaining the cleanliness of the wire collecting machine.

[0035] Further improvements are, Figure 7-10 As shown, a detection groove 203 is provided on the guide wire surface 204 perpendicular to the direction of advancement of the tow, and a sensor 7 for detecting the position of the tow is slidably provided in the detection groove 203 along its extension direction. A second guide rail 702 is provided on the inner wall of the sliding table 2 along the extension direction of the detection groove 203, and a second sliding seat 701 is slidably connected to the second guide rail 702. A locking screw 703 for locking the second sliding seat 701 and the second guide rail 702 is threadedly connected to the second sliding seat 701; in this way, the sensor 7 can be fixed at a predetermined position in the width direction of the guide wire surface 204 to detect the relative position between the sliding table 2 and the tow, thereby facilitating the alignment of the tow with the tape and improving the adhesion of the tape to the tow.

[0036] A method for using a carbon fiber tow collecting machine comprises the following steps: Step 1: Switch the winding roller 103 that has completed winding to the unloading station, move the sliding table 2 to allow the tow to enter between the wire pressing roller 4 and the wire guide surface 204 and press the tow, and then cut the tow between the two winding rollers 103; Step 2: driving the end of the tow to continue forward for winding, while simultaneously outputting the tape through the tape output mechanism so that the tape adheres to a fixed length on the side of the tow adjacent to the guide wire surface 204, and then cutting the tape; Step 3: The tow moves forward until the second shearing blade 502 is aligned with the middle of the tape and stops. The second shearing blade 502 is pressed down to cut the portion of the tape on one side of the tow along the width direction to form a fracture. Step 4: The tow continues to move forward until the second shearing blade 502 is aligned with the position of three-quarters of the length of the tape and stops. The airflow continuously ejected from the air jet 8 causes the tape behind the cut to flip to the side of the tow away from the guide surface 204; Step 5: The second shearing blade 502 is pressed down again, and at the same time, the pressing plate 504 is driven to press the flipped tape, so that the tape wraps around the tow from all sides and completely cuts the tape and the tow, thereby wrapping and trimming the end of the tow neatly. In step 6, the remaining tow and tape continue to move forward and be wound up, so that the tape is attached to the winding roller 103 to fix the end of the tow.
