Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber unwinding, in particular to a carbon fiber unwinding machine with a tension detection control device and a control method thereof. Background Art

[0002] Carbon fiber is a new type of fiber material with high strength and high modulus fiber with a carbon content of more than 90%. It has excellent physical properties, such as extremely high strength and hardness, but is relatively light in weight. The microstructure of carbon fiber is similar to graphite, composed of layers of carbon atoms. This special structure gives it excellent mechanical properties. In practical applications, carbon fiber is widely used in the aerospace field, such as manufacturing aircraft parts, because it can reduce weight while ensuring structural strength and stability; in automobile manufacturing, carbon fiber can reduce vehicle weight, improve fuel efficiency and performance; in the field of sporting goods, high-end bicycles, tennis rackets, golf clubs, etc. also often use carbon fiber to improve product performance and user experience;

[0003] During the processing of carbon fiber, it is usually necessary to use a carbon fiber spinning machine to assist in production and processing, and a carbon fiber unwinding machine is a device specifically used to process carbon fiber filaments. Its main function is to orderly release carbon fiber filament rolls. The Chinese patent with the announcement number "CN221093166U" discloses a unwinding device for carbon fiber, which includes: a support part; an unwinding roller, the outer side wall of the unwinding roller is wound with carbon fiber precursor; and a wire guide mechanism connected to the support part; the wire guide mechanism includes a moving part and a connecting arm; the first end of the connecting arm in the extension direction is formed with a wire guide part, the middle section of the connecting arm is rotatably connected to the moving part, and the moving part is provided with a limiting part corresponding to the second end of the connecting arm in the extension direction, so that the connecting arm can swing relative to the moving part; the moving part can also drive the connecting arm to move synchronously;

[0004] During use, the above-mentioned device can indeed play a role in assisting the swing adjustment, but in specific applications, its swing structure needs to be equipped with a separate electronic control structure to achieve adjustment. In this way, the overall adjustment cost is greatly increased. Not only that, in the application process of the device, it is impossible to flexibly and accurately detect and control the tensioning pressure during wire release, which makes it difficult to accurately grasp the tension condition during wire release during the entire application process. On the whole, the device has certain defects and shortcomings in overall use and processing, and the operation process is relatively cumbersome and inconvenient. In view of this, it is imperative to improve it. For example, in some production environments with strict cost control and extremely high precision requirements, this high adjustment cost and inaccurate tensioning pressure detection and control are very likely to lead to problems such as reduced production efficiency and fluctuations in product quality. Therefore, it needs to be improved.

[0005] To this end, we propose a carbon fiber unwinding machine with a tension detection and control device and a control method thereof to solve the above problems. Summary of the invention

A guide ring is fixedly installed on the top of the tension sensor. The carbon fiber filaments on the wire release roller pass through the inside of the guide ring. Balls are rotatably connected to the inside of the guide ring at equal intervals.

[0014] Furthermore, the tension control mechanism includes a slide groove and a drive component, the drive component is fixedly installed on a side of the fixed plate away from the base frame, the slide groove is opened at the upper end of the front side of the fixed plate, the interior of the slide groove is slidably connected with a slide frame, the drive component and the slide frame are fixedly connected, the interior of the slide frame is fixedly connected with a tensioning spring, the front end of the tensioning spring is fixedly connected with a slider, and the side of the slider close to the base is rotatably connected with a guide roller.

A screw is fixedly installed on the output end of the driving motor. The threaded sleeve is fixedly installed on the back of the sliding frame. The screw and the threaded sleeve are threadedly connected.

[0016] In a second aspect, the present invention provides a control method for a carbon fiber unwinding machine having a tension detection control device:

[0017] Step 1: Install the wire-releasing roller. First, pull out the handrail frame to make the handrail frame drive the limit block to move outward. The limit block moves outward and contacts the limit spring, causing the limit spring to be in a compressed state. Then, insert the slides at both ends of the wire-releasing roller into the interior of the mounting rail. When the limit groove and the limit block fit each other, release the handrail frame, and the limit spring is reset. The limit spring resets the limit block to eject and insert it into the inner side of the limit groove, completing the installation of the wire-releasing roller.

[0018] Step 2: Start the equipment and release the fiber, pass the carbon fiber fiber through the inside of the guide ring, and then wrap the outer end of the carbon fiber fiber around the external processing equipment, start the external equipment to drive the carbon fiber fiber to be extracted from the spinning roller. During this process, the guide roller stretches the carbon fiber fiber to make it tight;

[0019] Step 3: Detection during use: The taut carbon fiber wire pulls the guide ring, and the guide ring moves upward to pull the tension sensor. The PLC controller uses the tension sensor to monitor the overall pressure condition of the carbon fiber wire at all times;

[0020] Step 4: Tension control. If the pressure exceeds the maximum tolerance of the carbon fiber filament, on the one hand, you can choose to start the drive motor to drive the screw rod to operate, and the screw rod drives the threaded sleeve to move inward, so that the slide frame slides toward the inside of the slide groove, driving the guide roller to move inward, reducing the stretching amplitude of the carbon fiber filament, and thus reducing its tension. If the tension is insufficient, you can start the drive motor to drive the screw rod to reverse, drive the threaded sleeve outward, and drive the slider to drive the guide roller to move outward, further stretching the carbon fiber filament and increasing the tension of the carbon fiber filament during the overall release period.

[0021] Step 5: Alarm. During the wire laying process, the tension sensor detects the overall tension in real time. Once the tension changes significantly, it indicates that the equipment has a fault. At this time, the tension sensor will feed back the information to the PLC controller, and the PLC controller will start the alarm inside the chassis to notify the staff to carry out maintenance.

[0022] Step six: disassembling and assembling the wire-releasing roller. When the wire-releasing roller has finished releasing the wire, pull out the handrail to move the connecting shaft outward, and the connecting shaft pulls the limit block out of the limit groove. At this time, pull the wire-releasing roller out from between the mounting rails on the inner side of the turntable to complete the removal of the wire-releasing roller.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] Firstly, in the present invention, during use, the slide plate is inserted into the mounting rail, the handrail frame is pulled out to make the limit block move outward and compress the limit spring, the handrail frame is released after the slide plate is inserted, and the limit spring is reset to make the limit block fit into the limit groove to complete the installation, and after the wire release is completed, the handrail frame is pulled out to make the limit block disengage from the limit groove, and the wire release roller is pulled out and removed, so as to realize fast and flexible disassembly and assembly, and improve the convenience of use, and the tension control mechanism cooperates with the wire release mechanism, when in use, the carbon fiber wire is stretched out by the guide roller, passes through the guide ring to connect with the external equipment, and when in operation, the carbon fiber wire is tightened and the guide ring is pulled to drive the tension sensor, and the PLC controller detects the pressure accordingly, and when the pressure exceeds the maximum tolerance, the driving motor drives the screw rod to move the guide roller inward to reduce the tension; on the contrary, if the tension is insufficient, the tensioning spring is used for auxiliary protection during the wire release to prevent the carbon fiber wire from breaking, and a large change in tension indicates that the equipment is faulty, and the tension sensor feeds back to the PLC controller to start the alarm to notify maintenance, so as to improve the convenience of equipment use and the stability of wire release;

[0025] Thirdly, in the present invention, the guide mechanism and the driving mechanism are coordinated. When the wire-releasing roller rotates, the outer end turntable drives the first bevel gear to rotate, and the first bevel gear and the second bevel gear are engaged to drive them to rotate, thereby driving the first gear and the second gear to rotate. The rotation of the second gear can drive the transmission pulley to rotate, and the transmission drives the half gear to engage with the rack to make the linkage frame slide, thereby driving the guide ring to move, so that the carbon fiber wire is displaced, and the half gear rotates half a circle and engages with another rack to change the displacement direction, so as to cause the guide ring and the carbon fiber wire inside it to move back and forth, thereby ensuring stable and uniform wire release, relying on the power of the wire-releasing roller without the need for additional drive, low cost and stable wire release.

[0039] See also Figure 1-Figure 4The driving mechanism 7 includes a first bevel gear 71, a second bevel gear 72, a first gear 73 and a second gear 74. The first bevel gear 71 is rotatably connected to the outer side of the mounting plate 61 away from the fixed plate 2. The inner side of the first bevel gear 71 is fixedly connected to the turntable 62 away from the fixed plate 2.

The top of the transmission pulley 75 on the second gear 74 is fixedly connected to the bottom of the guide mechanism 5. The guide mechanism 5 includes a movable groove 51 and a half gear 52. The movable groove 51 is opened in the middle of the upper end of the fixed plate 2. The inside of the movable groove 51 is slidably connected with a linkage frame 53.

Through the ingenious cooperation of the first bevel gear 71, the second bevel gear 72, the first gear 73 and the second gear 74, the effective transmission and conversion of power is realized.

The tension control mechanism 3 is cleverly designed, the sliding frame 33 in the slide groove 31 realizes precise sliding through the driving component 32, and the tensioning spring 34 in the sliding frame 33 plays a role in buffering and assisting in adjusting the tension. The guide roller 36 connected to the slider 35 can effectively change the expansion amplitude of the carbon fiber filament to control the tension. The driving motor 321 in the driving component 32 provides power, and the threaded connection between the screw rod 323 and the threaded sleeve 322 realizes stable and precise drive control.

[0041] A control method for a carbon fiber unwinding machine with a tension detection control device:

[0042] Step 1: Install the wire-releasing roller 64. First, pull out the handrail frame 638 so that the handrail frame 638 drives the limit block 636 to move outward. The limit block 636 moves outward and contacts the limit spring 635, causing the limit spring 635 to be in a compressed state. Then, insert the slides 632 at both ends of the wire-releasing roller 64 into the interior of the mounting rail 631. When the limit groove 633 and the limit block 636 fit each other, release the handrail frame 638, and the limit spring 635 is reset. The limit spring 635 is reset to eject the limit block 636 and insert it into the inner side of the limit groove 633, thus completing the installation of the wire-releasing roller 64.

[0043] Step 2: Start the equipment and release the fiber, pass the carbon fiber fiber through the guide ring 562, and then wrap the outer end of the carbon fiber fiber around the external processing equipment, start the external equipment to drive the carbon fiber fiber to be extracted from the spinning roller. During this process, the guide roller 36 stretches the carbon fiber fiber to make it taut;

[0044] Step 3: Detection during use: the taut carbon fiber filament pulls the guide ring 562, and the guide ring 562 moves upward to pull the tension sensor 561. The PLC controller constantly monitors the overall pressure condition of the carbon fiber filament by means of the tension sensor 561;

[0045] Step 4: Tension control. If the pressure exceeds the maximum tolerance of the carbon fiber filament, on the one hand, the drive motor 321 can be started to drive the screw rod 323 to operate, and the screw rod 323 drives the threaded sleeve 322 to move inward, so that the slide frame 33 slides toward the inside of the slide groove 31, and drives the guide roller 36 to move inward, thereby reducing the stretching amplitude of the carbon fiber filament and thus reducing its tension. If the tension is insufficient, the drive motor 321 can be started to drive the screw rod 323 to reverse, drive the threaded sleeve 322 to move outward, and the threaded sleeve 322 drives the slider 35 to drive the guide roller 36 to move outward, further stretching the carbon fiber filament and increasing the tension of the carbon fiber filament during the overall release period.

[0046] Step 5: Alarm. During the wire-releasing process, the tension sensor 561 detects the overall tension in real time. Once the tension changes significantly, it indicates that the equipment has a fault. At this time, the tension sensor 561 will feed back the information to the PLC controller, and the PLC controller will start the alarm 10 inside the chassis 8 to notify the staff to carry out maintenance. It can be seen that the device as a whole can be quickly repaired and maintained to ensure the stability of wire-releasing;

[0047] Step six: disassembling and assembling the wire-releasing roller 64. When the wire-releasing roller 64 has finished releasing the wire, pull out the handrail frame 638 to drive the connecting shaft 637 to move outward, and the connecting shaft 637 pulls the limit block 636 out of the limit groove 633. At this time, pull the wire-releasing roller 64 out from between the mounting rails 631 on the inner side of the turntable 62 to complete the disassembly of the wire-releasing roller 64. The overall disassembly and assembly is relatively convenient.

10. A control method for a carbon fiber unwinding machine with a tension detection and control device, using the carbon fiber unwinding machine with a tension detection and control device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Install the wire-releasing roller (64). First, pull out the handrail frame (638) so that the handrail frame (638) drives the limit block (636) to move outward. When the limit block (636) moves outward, it contacts the limit spring (635), causing the limit spring (635) to be in a compressed state. Then, insert the slides (632) at both ends of the wire-releasing roller (64) into the interior of the mounting rail (631). When the limit groove (633) and the limit block (636) fit each other, release the handrail frame (638), and the limit spring (635) is reset. The limit spring (635) is reset to eject the limit block (636) into the inner side of the limit groove (633), thereby completing the installation of the wire-releasing roller (64). Step 2: Start the equipment and release the fiber, pass the carbon fiber fiber through the inside of the guide ring (562), and then wrap the outer end of the carbon fiber fiber around the external processing equipment, start the external equipment to drive the carbon fiber fiber to be extracted from the spinning roller. During this process, the guide roller (36) stretches the carbon fiber fiber to make it taut; Step 3: During the use process, the tightened carbon fiber filaments are pulled through the guide ring (562), and the guide ring (562) moves upward to pull the tension sensor (561), and the PLC controller constantly monitors the overall pressure condition of the carbon fiber filaments by means of the tension sensor (561); Step 4: Tension control. If the pressure exceeds the maximum tolerance of the carbon fiber filaments, on the one hand, the drive motor (321) can be started to drive the screw rod (323) to operate, and the screw rod (323) drives the threaded sleeve (322) to move inward, so that the slide frame (33) slides toward the inside of the slide groove (31), driving the guide roller (36) to move inward, reducing the expansion range of the carbon fiber filaments, and thus reducing their tension. If the tension is insufficient, the drive motor (321) can be started to drive the screw rod (323) to reverse, drive the threaded sleeve (322) to move outward, and the threaded sleeve (322) drives the slider (35) to drive the guide roller (36) to move outward, further expanding the carbon fiber filaments, and increasing the tension of the carbon fiber filaments during the overall release period. Step 5: Alarm. During the wire unwinding process, the tension sensor (561) detects the overall tension in real time. Once the tension changes significantly, it indicates that the equipment has a fault. At this time, the tension sensor (561) will feed back the information to the PLC controller, and the PLC controller will start the alarm (10) inside the chassis (8) to notify the staff to carry out maintenance. Step six: disassembling and assembling the wire-releasing roller (64). When the wire-releasing roller (64) has finished releasing the wire, pull out the handrail frame (638) to drive the connecting shaft (637) to move outward, and the connecting shaft (637) pulls the limit block (636) out of the limit groove (633). At this time, the wire-releasing roller (64) is pulled out from between the mounting rails (631) on the inner side of the turntable (62), and the wire-releasing roller (64) is removed.
