[0002] The winding and wire collecting device can be classified as a kind of handling equipment, mainly used for collecting, winding and packing the coils and fibers processed on the production line, so as to facilitate subsequent transportation, storage and processing. The wire collecting of large tow carbon fiber precursor filaments is an important link in the carbon fiber production process, which involves collecting the precursor filaments from the carbon fiber production equipment and arranging them into a form suitable for subsequent processing.

[0003] The existing wire collecting devices for large tow carbon fiber precursor filaments generally wind the precursor filaments onto a yarn bobbin. When the yarn bobbin reaches the maximum winding capacity, usually, workers need to manually remove the wound yarn bobbin from the roller and then replace it with a new unwound yarn bobbin. However, this operation method requires manual reel change operation, which is not convenient and has low efficiency. Workers need to observe the winding and wire collecting situation of the machine for a long time.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In the present invention, through structures such as the main body, winding module, and transmission module, after the detection unit and the contact button detect that the amount of fiber filaments wound on the yarn bobbin reaches the standard, the cylinder taking program of the device is started. The cutting unit is controlled by the controller to cut off the fiber filaments, and at the same time, the rotation speed of the servo motor is reduced to make the winding module reduce its rotation speed, and the distance sensor is started. When the induction bump is directly above the base, the distance between the induction bump and the distance sensor will reach the set value of the distance sensor. At this time, the distance sensor will send an electrical signal to the controller, causing the controller to control the servo motor to stop rotating, so that the winding module and the wound yarn bobbin stop rotating, preparing for the subsequent actions of the winding module. Then, the gas control unit is controlled to evacuate the air duct in the base, causing the piston block to drive the rack to displace. The displacement of the rack can drive the toothed ring meshing with it to rotate, and then drive the turntable, roller part, wound yarn bobbin, and transmission part to rotate 90 degrees to the right and enter the inner groove. During the rotation of the transmission part, its guide sleeve will be squeezed by the card slot and be pressed into the inner side of the card slot. The guide sleeve pressed into the card slot will drive the rod sleeve to displace, causing the push ring outside the rod sleeve to displace accordingly and no longer fix the respective driving parts. Due to the loss of the limit of the push ring, the respective driving parts displace towards the center of the roller shell under the elastic thrust of the second spring, and then drive the respective damping resistance strips protruding from the roller shell to contract towards the inside of the roller shell, so that the damping resistance strips no longer fix the wound yarn bobbin, enabling the roller part to automatically disconnect from the wound yarn bobbin after rotating 90 degrees to the right. At this time, the wound yarn bobbin that contacts the running conveyor belt after rotating 90 degrees can be conveyed to the storage box by the transmission module to the right, realizing that when the large tow carbon fiber precursor wire winding device winds the carbon fiber precursor wire, it can automatically perform the roll taking operation after reaching the winding amount of the yarn bobbin;

[0015] 2. In the present invention, through the structures such as the controller and the upper cylinder module, when the conveyor belt of the transmission module conveys and winds the yarn cylinder to the right, the infrared sensor will detect the passing of an object, indicating that the winding operation has been completed. At this time, the upper cylinder program of the device will be entered. The infrared sensor will send an electrical signal to the controller, causing the controller to control the electric push rod to extend, driving the fixed frame to drive the cylinder box to move downward, so that the cylinder box moves down to the set position, aligning the through port with the roller part. Then, control the cylinder to operate and extend, pushing the push plate and the baffle to move leftward. The leftward movement of the push plate will push the yarn cylinder to be replaced in the cylinder box out from the left through port, so that it is sleeved outside the roller part. At the same time, the leftward movement of the push plate will drive the baffle into the cylinder box to block the upper yarn cylinder, preventing the upper yarn cylinder from falling before the push plate resets. After the yarn cylinder is loaded onto the roller, reset the cylinder and the electric push rod to reset the baffle, the push plate and the cylinder box. At this time, control the gas control part by the controller to inflate the air duct of the base, causing the piston block to drive the rack to reset, and the movement of the rack will drive the toothed ring to reset and rotate, so that the turntable, the roller part, the transmission part and the replaced yarn cylinder outside the roller part reset and rotate 90 degrees. The reset rotation of the transmission part will cause the guide sleeve to disengage from the card slot. Losing the limit of the card slot, the compressed expansion spring will expand and reset to drive the rod sleeve and the push ring to reset and displace. The displacement of the push ring will extrude the various driving parts outward, causing the various damping resistance strips to be pushed outwards to position the replaced yarn cylinder. At this time, start the servo motor to operate to drive the winding module and the replaced yarn cylinder to rotate, and then start the wire guiding part to control the thread end of the fiber silk to move backward, so that the thread end of the fiber silk adheres to the adhesive tape of the anti-sticking ring, enabling the rotating anti-sticking ring to drive the fiber silk to wind on the outside of the yarn cylinder, realizing that the large tow carbon fiber precursor wire winding device can automatically load the roller with a cylinder. Through the above operations, the problem that the large tow carbon fiber precursor wire winding device generally performs the roll replacement operation manually, which is not convenient and has low efficiency, is solved.

The damping abutting strips 234 are all aligned with the slits of the tooth seat 232. Through this setting, each damping abutting strip 234 can be received into the slits of the tooth seat 232. One side of a group of damping abutting strips 234 away from the roller shell 231 is closely attached to the inner wall of the yarn tube 5. Through this setting, the damping abutting strips 234 can fix the position of the yarn tube 5; the toothed ring 224 is composed of a ring body and a quarter gear. The rack 219 meshes with the quarter gear of the toothed ring 224. Through this setting, the toothed ring 224 can only be driven to rotate 90 degrees by the rack 219, and then the rotating seat 22 can only rotate 90 degrees. The transmission module 7 is installed inside the inner groove 12 at the lower right side of the base 21. The transmission module 7 is composed of a group of four rollers, a transmission belt, side baffles, and a motor. The side baffles of the transmission module 7 are arranged at the inclined part of the transmission belt. Through this setting, it is avoided that the yarn tube 5 disengages from the transmission belt at the inclined part of the transmission belt after winding. The storage box 8 is installed inside the inner groove 12 on the right side of the transmission module 7. Through the provided storage box 8, the yarn tube 5 after winding the fiber silk thread 6 can be stored. The anti-sticking ring 25 is composed of an anti-ring and an annular adhesive strip installed in the front slot of the anti-ring. Through this setting, on the one hand, the anti-sticking ring 25 can limit the pushing distance of the yarn tube 5 when loading the upper tube, and on the other hand, its adhesive strip can adhere to the end of the fiber silk thread 6, so that the rotating anti-sticking ring 25 can drive the fiber silk thread 6 to wind on the outer side of the yarn tube 5.,

[0047] Such as Figure 1 , Figure 3 , Figures 26-28As shown in the figure, an upper cylinder module 9 located above the transmission module 7 is installed on the inner side of the inner groove 12. The upper cylinder module 9 includes an electric push rod 91 fixed to the inner wall of the inner groove 12. The lower driving end of the electric push rod 91 is fixedly connected to a fixing frame 92. A cylinder box 93 slidably connected to the middle rail groove of the inner groove 12 is fixedly connected to the left side of the fixing frame 92. Through openings 94 are provided at the lower positions of the left and right end faces of the cylinder box 93. A hopper 95 is fixedly connected to the upper side of the cylinder box 93. A cylinder 96 is fixedly connected to the inner side of the square opening of the vertical plate of the fixing frame 92. A push plate 97 located inside the right through opening 94 is fixedly connected to the left driving end of the cylinder 96. A baffle 98 slidably connected to the arc-shaped opening of the vertical plate of the fixing frame 92 is fixedly connected to the right side of the push plate 97. An infrared sensor 99 is installed on the lower side of the cylinder box 93. Through this setting, the upper cylinder module 9 can automatically perform the upper cylinder operation on the roller part 23; the fixing frame 92 is composed of a horizontal plate, a vertical plate, and fixed foot blocks. The inner width dimension of the cylinder box 93 is the same as the diameter dimension of the yarn cylinder 5, and the inner length dimension of the cylinder box 93 is the same as the length dimension of the yarn cylinder 5. Through this setting, the yarn cylinder 5 loaded into the cylinder box 93 is kept stable and cannot move horizontally. The lowest point of the through opening 94 is set on the same plane as the inner bottom surface of the cylinder box 93, and the inner diameter dimension of the through opening 94 is the same as the diameter dimension of the yarn cylinder 5. Through this setting, the lowermost yarn cylinder 5 in the cylinder box 93 can be moved out through the through opening 94. The diameter dimension of the push plate 97 is the same as the diameter dimension of the yarn cylinder 5. Through this setting, the push plate 97 can push the yarn cylinder 5 out from the left through opening 94. The upper curved surface of the push plate 97 and the upper curved surface of the baffle 98 are set with a smooth transition. Through this setting, the leftward movement of the push plate 97 will drive the baffle 98 into the cylinder box 93 to block the upper yarn cylinder 5 and prevent the upper yarn cylinder 5 from falling before the push plate 97 resets, so that the push plate 97 can be reset later. The length dimension of the baffle 98 is greater than the length dimension of the cylinder box 93. The infrared sensor 99, the electric push rod 91, and the cylinder 96 are all electrically connected to the controller 10. Through this setting, the controller 10 can control the actions of the cylinder 96 and the electric push rod 91 after receiving the infrared sensor 99.

[0048] Workflow: The rewinding operation of the large tow carbon fiber preform winding device for the fiber thread 6 is as follows. Note 1: All electrical equipment in this solution is powered by an external power supply, and all electrical equipment in this solution is controlled by the controller 10. Note 2: The operation of the reciprocating drive assembly 141 is as follows. By starting the motor, the reciprocating lead screw rotates, and the rotation of the reciprocating lead screw drives the reciprocating nut sleeve engaged with it to perform reciprocating displacement in the front and back directions. The operation of the cutting part 15 is as follows. By starting the motor, the lead screw rotates, and the rotation of the lead screw can drive the nut sleeve helically connected to it to displace, and the displacement of the nut sleeve can drive the knife bar and the cutting knife to displace. By the displacement of the cutting knife, the fiber thread 6 between the pressure roller 163 and the rotating roller 18 can be cut off. Note 3: As the fiber thread 6 wound on the surface of the yarn bobbin 5 increases, it will push the pressure roller 163, the folding rod 162, and the linkage rod 166 to the left. The displacement of the linkage rod 166 will drive the lower guide wheel rail plate 144 to displace through the linkage sleeve 145, so that the distance between the lower guide wheel rail plate 144 and the pressure roller 163 is always maintained. The displacement of the folding rod 162 will activate the contact button 17 after the winding amount of the yarn bobbin 5 reaches the standard, indicating that the winding amount of the yarn bobbin 5 reaches the standard and a rewinding operation is required.First, a set of guide rollers 13, pressure rollers 163, and rotating rollers 18 can roughly guide the walking displacement of the fiber silk thread 6. The upper guide wheel plate 142 and the lower guide wheel rail plate 144 driven by the reciprocating drive assembly 141 can conduct the passing fiber silk thread 6 in the front-back direction, enabling the fiber silk thread 6 to be evenly wound on the outer side of the yarn bobbin 5. When the detection unit 16 and the contact button 17 detect that the amount of the fiber silk thread 6 wound on the yarn bobbin 5 reaches the standard, the tube-taking program of the device is started at this time. The controller 10 controls the cutting unit 15 to cut off the fiber silk thread 6, and at the same time reduces the rotation speed of the servo motor 19 to make the winding module 2 reduce the rotation speed, and the distance sensor 3 is started. When the induction bump 26 is directly above the base 21, the distance between the induction bump 26 and the distance sensor 3 will reach the set value of the distance sensor 3. At this time, the distance sensor 3 will send an electrical signal to the controller 10, causing the controller 10 to control the servo motor 19 to stop rotating, so that the winding module 2 and the wound yarn bobbin 5 stop rotating, preparing for the subsequent operation of the winding module 2. Then, the gas control unit 4 is controlled to evacuate the air duct 216 in the base 21, so that the piston block 218 drives the rack 219 to displace. The displacement of the rack 219 can drive the engaged gear ring 224 to rotate, and then drive the turntable 22, the roller part 23, the wound yarn bobbin 5, and the transmission part 24 to rotate 90 degrees to the right and enter the inner groove 12. During the rotation of the transmission part 24, its guide sleeve 245 will be squeezed by the card slot 212 and be pressed into the inner side of the card slot 212. The guide sleeve 245 pressed into the card slot 212 will drive the rod sleeve 243 to displace, so that the push ring 246 outside the rod sleeve 243 will displace accordingly and no longer fix the respective driving parts 233. Due to the loss of the limit of the push ring 246, the respective driving parts 233 displace towards the center of the roller shell 231 under the elastic thrust of the second spring 235, and then drive the respective damping abutting strips 234 protruding from the roller shell 231 to contract into the roller shell 231, so that the damping abutting strips 234 no longer fix the wound yarn bobbin 5, enabling the roller part 23 to automatically disconnect from the wound yarn bobbin 5 after rotating 90 degrees to the right. At this time, the wound yarn bobbin 5 that contacts the running conveyor belt after rotating 90 degrees can be conveyed to the storage box 8 to the right by the transmission module 7, enabling the large tow carbon fiber precursor wire winding device to automatically perform the take-up operation when the winding amount of the carbon fiber precursor wire reaches the amount wound on the yarn bobbin 5;The operation of the upper bobbin is as follows. When the conveyor belt of the transmission module 7 conveys the wound bobbin 5 to the right, the infrared sensor 99 will detect the passing of an object, indicating that the bobbin-taking operation has been completed. At this time, the upper bobbin program of the device will be entered. The infrared sensor 99 will send an electrical signal to the controller 10, causing the controller 10 to control the electric push rod 91 to extend, so that the fixing bracket 92 drives the bobbin box 93 to move downward, and the bobbin box 93 is moved down to the set position, making the through port 94 aligned with the roller part 23. Then, control the cylinder 96 to operate and extend, pushing the push plate 97 and the baffle 98 to move leftward. The leftward movement of the push plate 97 will push the bobbin 5 to be replaced in the bobbin box 93 out from the left through port 94, making it sleeved on the outside of the roller part 23. At the same time, the leftward movement of the push plate 97 will drive the baffle 98 into the bobbin box 93 to block the upper bobbin 5, preventing the upper bobbin 5 from falling before the push plate 97 resets. After the bobbin 5 is loaded onto the upper bobbin, reset the cylinder 96 and the electric push rod 91 to reset the baffle 98, the push plate 97 and the bobbin box 93. At this time, control the gas control part 4 by the controller 10 to inflate the air duct 216 of the base 21, so that the piston block 218 drives the rack 219 to reset, and the movement of the rack 219 will drive the toothed ring 224 to reset and rotate, making the turntable 22, the roller part 23, the transmission part 24 and the replaced bobbin 5 outside the roller part 23 reset and rotate 90 degrees. The reset rotation of the transmission part 24 will cause the guide sleeve 245 to disengage from the card slot 212. Losing the limit of the card slot 212, the compressed expansion spring 244 will expand and reset to drive the rod sleeve 243 and the push ring 246 to reset and displace. The displacement of the push ring 246 will then extrude the respective driving parts 233 outward, so that the respective damping bars 234 are pushed outwards to position the replaced bobbin 5. At this time, start the servo motor 19 to operate and drive the winding module 2 and the replaced bobbin 5 to rotate. Then start the wire guiding part 14 to control the wire end of the fiber thread 6 to move backward, so that the wire end of the fiber thread 6 adheres to the adhesive tape of the anti-sticking ring 25, so that the rotating anti-sticking ring 25 can drive the fiber thread 6 to be wound on the outside of the bobbin 5, enabling the large tow carbon fiber precursor wire winding device to automatically load the bobbin onto the roller. Through the above operations, the device can automatically perform the bobbin-changing operation.;
