Description

Technical Field

[0001] The present invention relates to a special fiber hot stretching and shaping cutting machine system and method, belonging to the technical field of textile equipment. Background Art

[0002] During the processing of special fiber filaments (such as carbon fiber bundles, glass fiber bundles, etc.), it is necessary to tie knots at both ends and cut to a fixed length. However, the biggest feature of these fiber bundles is their high hardness and good tensile and bending strength at room temperature. Therefore, the winding technology of special fibers is different from that of other ordinary fibers. In the past, multiple steps were required by manual labor, and various machines were used for the stretching, heating and reshaping, tying knots at both ends, cutting to a fixed length, cold shaping and other processes of special fibers.

[0003] Existing technical solution: As shown in Figure 1 , first, manually place the long roller of the special fiber raw yarn bobbin 01 on the unwinding frame. After the yarn end of the raw yarn bobbin is manually threaded through the yarn and led to the cooling furnace 03, start the actively rotating yarn unwinding shaft device at the position of the special fiber raw yarn bobbin 01 to keep the special fiber raw yarn bobbin 01 unwinding at a constant speed. When the unwound raw yarn passes through the heating and curing furnace 02, it maintains a plastic stretching form, then enters the cooling furnace 03 for shaping after being stretched and straightened. At the same time, after shaping, it enters the knotting station 04 and the cutting station 05 through manual intervention. Those special fiber bundles that have been cut to the standard length will flow into the collection box, and then be woven or subjected to other extended processing.

[0004] The above-mentioned technology still has the following defects: 1) High input cost. The stretching process of special fibers requires a heating and curing furnace, and a large amount of funds need to be invested in site construction and the purchase of hardware equipment.

[0005] 2) The heating and cooling processes require the construction of a production line, which occupies a large amount of factory space, and the heating and cooling rooms consume a large amount of energy, which is not energy-saving and environmentally friendly; 3) The processes are too scattered and require a large amount of manual labor. The labor cost is very high. Especially in the high-temperature heating and cooling shaping and cutting links, manual operations will also generate many uncertain safety hazards.

[0008] Further, the degumming tension device includes a servo motor 1, an overfeed roller disc and a yarn guide; the yarn guide is located on one side of the mounting bracket below the servo motor 1 and the overfeed roller disc; the overfeed roller disc rotates clockwise through the servo motor 1 to drive the special fiber bundle to be conveyed upward and introduced to the auxiliary heating multi-roll combination device.

[0009] Further, the auxiliary heating multi-roll combination device is arranged in the upper middle part of the feeding frame, and servo drive motors are installed at both ends of its tension rolls, and there are 1-2 heating rolls; there are 1-2 introducing support rolls, which are located on the left side of the heating roll close to the degumming tension device; there are 1-2 guiding rolls, which are located on the right side of the heating roll close to the knotting device.

[0010] Further, the swinging clamp mechanism includes a servo motor 2 installed below the auxiliary heating multi-roll combination device; a rotating arm is connected to one side of the servo motor 2; a cylinder chuck is connected to one side of the rotating arm.

[0011] Further, the knotting device includes a knotting device assembly and a lifting hook assembly; the knotting device assembly includes a stepping motor, an eagle beak knotting device and a mounting frame; the stepping motor is connected to the eagle beak knotting device on one side; the lifting hook assembly includes a telescopic cylinder and a hook; the hook is installed at one end of the telescopic cylinder; a distance sensor is arranged on one side of the eagle beak knotting device.

[0012] Furthermore, the sliding clamp mechanism specifically includes a cylinder, a connecting plate, a vertical chuck, a guide steel cable, a slide rail, a servo motor three, a guide wheel and a slider; a guide wheel is connected to one side of the servo motor three; a guide steel cable is arranged on the guide wheel; a slide rail is arranged on the feeding frame below the lead steel cable; a slider is installed on the slide rail and the lead steel cable; a cylinder is installed on the slider; the lower end of the cylinder is connected to the connecting plate; one side of the connecting plate is connected to the vertical chuck; a sensor is installed on one side of the vertical chuck.

[0013] The method based on the above-mentioned special fiber heat stretching and shaping cutting machine system includes the following steps: Step S1: First, the special fiber raw yarn bobbin is fixed on the feeding frame of the machine, and then the special fiber bundle is pulled into the debonding tension device, and then continues to penetrate into the auxiliary heating multi-roller combination device through tension guidance; Step S2: After being heated by the heating roller, the end of the special fiber bundle is led out by the lead-out roller, and then the cylinder chuck clamps the end of the special fiber bundle and drives the end of the special fiber bundle to be led out downward by a distance through the rotating arm; Step S3: The lifting knotting device slides downward, and the knotter is transported to the lead-out end of the special fiber bundle, and the special fiber bundle is hooked by a hook and lifted up by a telescopic cylinder. Then, the distance sensor receives a detection signal, and then controls the stepper motor to drive the hawk's beak knotter to knot the first section of the special fiber bundle; Step S4: Then the lifting knotting device drives the knotter to retract upward to its original position. When the sliding clamp mechanism slides to the left limit point, the vertical clamp clamps the end of the special fiber bundle, and the swing clamp mechanism is released and flipped downward. At this time, the vertical clamp pulls the special fiber bundle to the right slowly; during the pulling process, the special fiber bundle is cooled and shaped by the cold air system; Step S5: When the vertical chuck reaches the designated position on the right side of the machine, the swinging clamp mechanism clamps the middle section of the special fiber bundle, and then drives the middle section of the special fiber bundle downward for a distance, and the lifting knotting device slides downward again, and the knotting operation of step S3 is repeated. At this time, when the sliding clamp mechanism slides to the left limit point again, the vertical chuck clamps the middle section of the special fiber bundle and pulls it to the right. At this time, the cutter on the knotter cuts one side of the knotting position of the special fiber bundle to form a cut product, and then the cut product falls into the finished product collection box; after the processing is completed, the above steps are repeated to continuously form cut products.

[0014] Furthermore, the automatic feeding and conveying process in step S2 is as follows: When operating the upper yarn, the special fiber bundle passes through the yarn guide and enters the overfeed roller disc. The internal toothed friction disc of the roller disc is driven by the first servo motor to rotate clockwise, driving the special fiber bundle to be conveyed upward and passing through the inlet idler roller, heating roller, and outlet roller in sequence before being discharged. The clamping preparation process in step S2 is as follows: When the system issues an instruction for the second servo motor to rotate, driving the rotating arm to lift upward. When the sensor on the cylinder chuck touches the special fiber bundle, the cylinder chuck clamps the special fiber bundle and drags it downward to stretch and rotate to the specified position. At this time, the hook probes downward and hooks the middle section of the special fiber bundle, preparing for the next knotting process.

[0015] Furthermore, the first-stage knotting process in step S3 is as follows: The hook pulls the special fiber bundle upward to the working position of the eagle beak knotter. The eagle beak starts to open and clamp the special fiber bundle; under the drive of the stepping motor, it starts to rotate in the reverse direction. At the same time, the hook drags the other end of the special fiber bundle upward to form a certain pulling force, and finally a knot is formed not far from the right end of the special fiber bundle. At this time, the first knot is completed.

[0016] Furthermore, in step S4, the specific conveying principle of the first section of the special fiber bundle after the first knot is tied is as follows: After tying 1 knot in the first section, the eagle beak loosens, and the hook moves downward with the special fiber bundle; After reaching the set position, the third servo motor is started. The guide pulley rotates to drive the lead wire rope to move to the left. When the slider slides to the left to the specified position on the left side along the slide rail, the cylinder controls the connecting plate to move downward. When the sensor detects the special fiber bundle, the vertical chuck clamps the special fiber bundle while the cylinder chuck loosens, and then drags the special fiber bundle to move to the right to the specified position on the right side along the slide rail.

[0017] The beneficial effects of the present invention are as follows: 1. The system meets the needs of users for fully automated process production, reduces the intensity of repetitive labor of workers, and some process steps implement full automation to minimize manual operations.

[0018] 2. The system adopts an automatic unwinding tension device, a temperature-controlled heating roller, an automatic knotting device, an automatic air-cooling shaping and cutting function, greatly integrating the functionality of the system.

[0019] 3. The system produces through the automation of each functional device. In particular, the automated modules replace the previous manual operations in dangerous areas such as high temperature and high heat, reducing operation risks such as scalding and cutting injuries.

[0029] Referring to Figures 11 - 14 , the sliding clamp mechanism 6 specifically includes a cylinder 61, a connecting plate 62, a vertical clamp 63, a lead wire rope 64, a slide rail 65, a servo motor three 66, a guide wheel 67 and a slider 68; one side of the servo motor three 66 is connected with a guide wheel 67; a lead wire rope 64 is arranged on the guide wheel 67; a slide rail 65 is arranged on the feeding frame 10 where the lead wire rope 64 is located below; a slider 68 is installed on the slide rail 65 and the lead wire rope 64; a cylinder 61 is installed on the slider 68; the lower end of the cylinder 61 is connected with the connecting plate 62; one side of the connecting plate 62 is connected with the vertical clamp 63; a sensor is installed on one side of the vertical clamp 63 to detect the position state of the special fiber bundle 11.

[0030] A process method of a special fiber hot stretching and shaping cutting machine system, characterized by including the following steps: Step S1: First, fix the special fiber raw silk bobbin 1 on the feeding frame 10 of the machine, and the special fiber bundle 11 wound on the special fiber raw silk bobbin 1 is drawn into the unwinding tension device 2, and continues to pass through the auxiliary heating multi-roller combination device 3 under the guidance of the tensioner; Step S2: After heating by the heating roller 32 in the auxiliary heating multi-roller combination device 3, the end of the special fiber bundle 11 is led out by the outlet roller 33. At this time, the cylinder chuck 81 in the swinging clamp mechanism 8 is controlled by the PLC program to clamp the end of the special fiber bundle 11, and the end of the special fiber bundle 11 is driven to be led out downwards by a certain distance under the action of the rotating arm 82. At this time, the lifting knotting device 4 slides downwards; Step S3: When the lifting and knotting device 4 slides downward, the knotter 5 is conveyed to contact the led-out section of the special fiber bundle 11; the hook 522 of the lifting hook assembly 52 hooks the special fiber bundle 11 and moves upward through the telescopic cylinder 521. Subsequently, when reaching the specified position, the distance sensor on one side of the eagle-beak knotter 512 detects that the special fiber bundle 11 reaches the specified position beside the eagle-beak knotter 512. Then, under program control, the stepping motor 511 drives the eagle-beak knotter 512 to move and perform knotting treatment on the first section of the special fiber bundle 11; Step S4: After the first section is processed, at this time, the lifting and knotting device 4 drives the knotter 5 to retract upward to the original position. The swinging clamp mechanism 8 flips upward with the special fiber bundle 11 with one knot already tied. At this time, the sliding clamp mechanism 6 slides from the right side to the left side of the machine. When the sliding clamp mechanism 6 slides to the left limit point, at this time, the swinging clamp mechanism 8 also flips to the specified position. The vertical clamp 63 of the sliding clamp mechanism 6 opens the clamp and then clamps the end of the special fiber bundle 11. The swinging clamp mechanism 8 releases and flips downward to the landing position. At this time, the vertical clamp 63 pulls the special fiber bundle 11 slowly to the right; Step S5: During the slow pulling of the special fiber bundle 11 to the right, it passes above the cold air system 9. The cold air blown upward in the cold air system 9 cools and shapes the special fiber bundle 11. At this time, to ensure that there is a certain length compensation surplus in the stretching middle section of the special fiber bundle 11, and the surplus length is convenient for tying the second knot, the pulling speed of the sliding clamp mechanism 6 is slightly lower than the speed at which the special fiber bundle 11 is led out from the auxiliary heating multi-roller combination device 3; Step S6: When the vertical clamp 63 pulls the end of the special fiber bundle 11 to the specified position on the right side of the machine, the swing clamp mechanism 8 flips upward and rises, and then clamps the middle section of the special fiber bundle 11 again. At this time, the vertical clamp 63 releases the rightmost end of the special fiber bundle 11, and the rightmost end of the special fiber bundle 11 falls into the finished product collection box 13. At this time, the swing clamp mechanism 8 that has clamped the middle section of the special fiber bundle 11 clamps the middle part of the special fiber bundle 11 and drives the middle part of the special fiber bundle 11 to be led out downward by a certain distance. At this time, the lifting knotting device 4 slides downward again, and repeats the knotting operation in step S3. After the second knotting is completed, when the sliding clamp mechanism 6 slides to the left limit point again, the swing clamp mechanism 8 also flips to the specified position. After the vertical clamp 63 of the sliding clamp mechanism 6 opens the clamp, it clamps the middle part of the special fiber bundle 11. The swing clamp mechanism 8 releases and flips downward to the lowered position. At this time, the vertical clamp 63 drags the middle section knotting position of the special fiber bundle 11 and slowly pulls it to the right. At this time, the cutter on the knotter 5 receives an instruction to cut the left side of the middle section of the special fiber bundle 11 that has been knotted. The cut special fiber bundle with a fixed length and two knots is the cut finished product 12. The vertical clamp 63 continues to bring the left end of the cut finished product 12 into the receiving range of the finished product collection box 13 and then releases it, thus completing the entire movement process.

[0031] Preferably in this embodiment, the specific automatic feeding and conveying principle of step S2 is as follows: When operating the yarn feeding, the operator places the special fiber raw yarn bobbin roll 1 at the specified position on the machine table, and leads out the special fiber bundle 11 on the special fiber raw yarn bobbin roll 1. The special fiber bundle 11 passes through the yarn guide 23 and enters the overfeed roller disc 22. The internal toothed friction disc of the roller disc is driven by the first servo motor 21 to rotate clockwise, driving the special fiber bundle 11 to be conveyed upward. The special fiber bundle 11 is placed on the clockwise rotating introduction roller 31 and enters the inner side of the counterclockwise rotating heating roller 32, and then is screwed into a set of export rollers 33 that rotate forward and backward and then discharged; Refer to Figures 5 - 6 , the specific clamping preparation principle of step S2 is as follows: After the special fiber bundle 11 comes out of the auxiliary heating multi-roller combination device 3, the special fiber bundle 11 continuously continues to be extruded from the end roller and extends downward. When the system issues an instruction for the second servo motor 83 to rotate and drive the rotating arm 82 to lift upward, when it lifts 30° - 35°, the sensor on the cylinder chuck 81 touches the special fiber bundle 11, and the end cylinder chuck of the cylinder chuck 81 opens. The special fiber bundle 11 continues to extend into the gap of the cylinder chuck 81. At this time, the clamp clamps the special fiber bundle 11 and drags the special fiber bundle 11 to be stretched downward and rotated to the specified position. At this time, the hook 522 of the lifting hook assembly 52 descends and holds and hooks the extra middle section of the special fiber bundle 11 to make preparations before the next knotting process.

[0032] Referring to Figures 7 - 10 , the principle of the first knotting process in step S3 is as follows: Driven by the telescopic cylinder 521, the hook 522 pulls up the special fiber bundle 11. At this time, the cylinder chuck 81 that originally pulled the right end of the special fiber bundle 11 is released. The hook 522 continues to lift the special fiber bundle 11 to a position opposite to the eagle beak knotter 512. When the distance sensor detects that the special fiber bundle 11 reaches the specified position on the edge of the eagle beak, the eagle beak starts to open and adjusts its angle to clamp the movable end of the special fiber bundle 11. At this time, the preparatory work before knotting the fiber bundle 11 is completed; the eagle beak of the eagle beak knotter 512 clamps the head of the special fiber bundle 11 and starts to rotate 360° in the reverse direction under the drive of the stepping motor 511. At the same time, the hook 522 drags the other end of the special fiber bundle 11 upward to form a certain pulling force. With the cooperation of this pulling force and the clamping force on the eagle beak, a knot is finally formed not far from the right end of the special fiber bundle 11. At this time, the first knot is completed. Similarly, the working process of the middle knot in the second section is the same as the above operation process.

[0033] Referring to Figures 11 - 12 , the conveying principle of the first section of the special fiber bundle 11 after tying the first knot is specifically as follows: After the special fiber bundle 11 passes through the knotter assembly 51 and ties 1 knot in the first section, the eagle beak on the knotter assembly 51 is released, and the special fiber bundle 11 falls onto the hook 522. The hook 522 moves downward with the special fiber bundle 11 under the control of the telescopic cylinder 521; After reaching the set position, the cylinder chuck 81 clamps the head of the special fiber bundle 11 with 1 knot tied. At this time, the servo motor three 66 is started, and the guide pulley 67 rotates to drive the lead wire rope 64 to move to the left. One side of the slider 68 is fixedly installed on the lead wire rope 64. Under the driving force of the lead wire rope 64 moving to the left, the slider 68 slides to the left along the slide rail 65. When sliding to the specified position on the left, the cylinder 61 controls the connecting plate 62 to move downward. The sensor at the end of the vertical chuck 63 detects the head of the special fiber bundle 11. When the head of the special fiber bundle 11 is detected downward, the vertical chuck 63 clamps the head of the special fiber bundle 11. At this time, the cylinder chuck 81 is released, and the vertical chuck 63 clamps and drags the special fiber bundle 11 to move to the right along the slide rail 65 until the head of the special fiber bundle 11 is pulled to the specified position on the right. During the pulling process, the cold air system 9 blows the compressed air cooled by the internal water circulation of the cold air system 9 to the passing position of the traction of the special fiber bundle 11, so as to realize the cooling and shaping of the first section of the special fiber bundle 11; Referring to Figures 13 - 14 , the principle of tying the second knot and cutting and conveying the tail of the special fiber bundle 11 is specifically as follows: After the first knot is tied at the leading end of the special fiber bundle 11 and the conveyance is completed, the vertical clamp 63 is released. The leading end of the special fiber bundle 11 drops into the finished product collection box 13 below. Then, the vertical clamp 63 returns to the left position driven by the lead wire rope 64. During this process, the hook 522 on the lower side of the lifting and knotting device 4 hooks up the trailing end of the special fiber bundle 11 again, and the above-mentioned knotting steps are repeated to process the second knot. Before repeating the knotting steps, the left side of the second knot on the special fiber bundle 11 is cut off, and a cut finished product 12 with knots at both ends drops from the special fiber bundle 11. After the processing is completed, the above steps are repeated; the vertical clamp 63 clamps the left side of the cut finished product 12 and conveys it to the left. After reaching the specified position, the vertical clamp 63 releases the clamp, and the entire cut finished product 12 drops into the finished product collection box 13; the new fiber end of the special fiber bundle 11 is continuously received and clamped by the upwardly flipped cylinder clamp 81 to form the cut finished product 12.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
