Description

Technical Field

[0001] The present application relates to the technical field of carbon fiber, and in particular to a winding device for a carbon fiber widened tow woven fabric. Background Art

[0002] Carbon fiber widened tow woven fabric is a fabric formed by widening the carbon fiber raw yarn with a width of about 6mm, and then weaving the warp and weft yarns through a loom. The loom usually includes a loom body and a winding device. The loom body is mainly responsible for weaving the warp and weft yarns into fabrics, while the winding device is mainly responsible for collecting the fabric into rolls for subsequent use. In recent years, relevant scholars have found through a large number of experiments that the two main factors affecting the weaving performance of carbon fiber are the characteristics of the carbon fiber itself and the process parameters during weaving and winding. On the one hand, the carbon fiber fabric itself has the characteristics of brittleness and low fracture toughness. It is easy to cause fluffing and broken wires during the weaving process, which affects the performance of the fabric. On the other hand, the stress distribution in the carbon fiber fabric is very uneven, especially at the intersection of the warp and weft yarns. If the force is uneven, the carbon fiber fabric may be greatly deformed or damaged. The uneven force and deformation of the fabric usually occur in the winding stage, such as unreasonable structure and layout of the winding device, offset or uneven force during the fabric traction process, etc., which may affect the fabric winding effect, product quality, equipment service life, maintenance cost and production efficiency. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the carbon fiber widening tow woven fabric winding device in the utility model is:

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0050] The utility model relates to a carbon fiber widening tow woven fabric winding device. Figure 1 FIG. 2 shows a schematic diagram of the structure of the device in an embodiment. Figure 1 As shown, the device includes a winding device chassis 1, a first supporting structure 2, a second supporting structure 3, a tension adjustment mechanism 4, a traction roller 5, a winding mechanism 6, a paper release mechanism 7, and a deceleration drive system 8. The first supporting structure 2 and the second supporting structure 3 are respectively connected to the winding device chassis 1. The first supporting structure 2 is fixedly connected to the winding device chassis 1 by bolts. The first supporting structure 2 is used to support the loom body. At the same time, a first guide roller 21, a second guide roller 22, and a third guide roller 23 are rotatably arranged between the two sides to pull the fabric 9, reduce its deviation in the traction path, and put it in a tensioned state. The second supporting structure 3 is used to support the winding mechanism 6. Figure 2 The structural diagram of the winding mechanism 6 is shown. Figure 1 , Figure 2 As shown, in this embodiment, the second supporting structure 3 includes a transmission frame 31 arranged on one side and a winding frame 32 arranged on both sides. The transmission frame 31 is connected to the winding frame 32 on the same side. The transmission frame 31 and the winding frame 32 are respectively arranged on the winding device base frame 1 and can be fixedly connected by bolts. The height setting of the winding frame 32 should meet the requirements of the fabric winding path angle on the one hand, and ensure that the requirements of the winding length, i.e., the winding diameter, are met on the other hand. The winding frame 32 is designed to reduce weight on the basis of meeting the support strength.

[0051] like Figure 1 As shown, the fabric 9 is sequentially pulled to the first guide roller 21, the second guide roller 22, the third guide roller 23, the tension adjustment mechanism 4, the traction roller 5, and the winding mechanism 6 through the main working surface of the loom. In this embodiment, the winding mechanism 6 is independently arranged from the main loom body, and is convenient for winding up and down; when there are quality problems, it is convenient to adjust; at the same time, the winding path is extended, and the fabric is fully flattened in the winding path, eliminating the stress concentration phenomenon and preventing the fabric 9 from deformation. In other embodiments, the winding mechanism 6 can also be arranged on the same supporting structure as the main loom body, and the number of guide rollers can be set according to the distance between the winding mechanism 6 and the main working surface of the loom body.

[0052] like Figure 2As shown, the winding mechanism 6 includes a winding roller 61 and a winding shaft 62. A safety chuck 63 is provided on the winding frame 32 for placing the winding roller 61. This method is used for quick and convenient winding up and down. One end of the winding shaft 62 is connected to the safety chuck 63 on this side through a coupling 64, and the other end is rotatably provided on the transmission frame 31. The winding roller 61 can be set as an air expansion roller to meet the conditions of using pipes of different diameters to collect fabrics. In other embodiments, a cross slide can also be provided on one side of the winding roller 61. Through fine-tuning of the cross slide, it is ensured that the winding tension of the entire fabric surface is consistent, thereby improving the winding quality.

[0053] like Figure 1 As shown, the deceleration drive system 8 includes a winding motor 81 and a winding reducer 82. The winding reducer 82 is connected to the winding motor 81 to reduce the rotation speed of the winding motor and increase the torque. Figure 3 The transmission structure diagram of the device is shown in FIG. Figure 2 , Figure 3 As shown, the transmission structure includes: a first gear 84, a first adjustment shaft 33 and a second gear 34 and a first sprocket 35 arranged thereon, a second sprocket 65 arranged on the winding shaft 62, an adjustment chain 36 connecting the first sprocket 35 and the second sprocket 65, a second adjustment shaft 37 for adjusting the tightness of the adjustment chain 36, and a second adjustment shaft auxiliary part 38. The winding reducer 82 is arranged on the transmission frame 31 through a connecting member 85, and a first gear 84 is arranged on one side of the winding reducer output shaft 83. The first adjustment shaft 33 is rotatably arranged on the transmission frame 31, and a second gear 34 is arranged on the first adjustment shaft 33. The first gear 84 and the second gear 34 are meshed and transmitted. The first adjustment shaft 33 is also provided with a first sprocket 35, which is located outside the second gear 34. The second sprocket 65 is arranged on the winding shaft 62, and the first sprocket 35 and the second sprocket 65 are connected and transmitted through the adjustment chain 36. One end of the second adjustment shaft auxiliary part 38 is swingably connected to the transmission frame 31, and the other end is connected to the second adjustment shaft 37. The second adjustment shaft 37 contacts the outer side of the adjustment chain 36 on the driven side, and the tightness of the adjustment chain 36 is adjusted with the swing of the second adjustment shaft auxiliary part 38. Preferably, the second adjustment shaft 37 is rotatably connected to the second adjustment shaft auxiliary part 38, and when adjusting the tightness of the adjustment chain 36, the wear of the adjustment chain 36 and the second adjustment shaft 37 during the working process can be reduced, the service life can be extended, and the maintenance cost can be reduced.

[0054] The working mode of winding is that the weft width is preset through the PLC control program. When each weft is woven, the winding motor 81 drives the winding reducer output shaft 83 to rotate a corresponding distance, and the first gear 84 is meshed with the second gear 34 for transmission, and drives the first adjustment shaft 33 to rotate, thereby rotating the first sprocket 35. The first sprocket 35 and the second sprocket 65 are connected and driven through the adjustment chain 36, and drive the winding shaft 62 to rotate for winding. The second adjustment shaft 37 adjusts the tightness of the adjustment chain 36 with the swing of the second adjustment shaft auxiliary part 38, so that the adjustment chain 36 is always in a tensioned state.

[0055] The carbon fiber widening tow woven fabric winding device in the utility model has an optimized transmission structure and layout, which can effectively play a buffering role, accurately control the winding distance, reduce the adverse effects on fabric performance that may be produced during the winding process, improve the winding effect and product quality, and reduce damage to the deceleration drive system and winding mechanism, reduce equipment failure rate and maintenance costs, and improve production efficiency. In actual production, since the carbon fiber widening tow woven fabric winding is non-continuous winding, the operating speed is relatively low. Each time a weft yarn is woven, the winding shaft is driven to rotate a corresponding distance, and the deceleration drive system is started and stopped relatively frequently during the winding process.

[0056] (1) The deceleration drive system drives the winding mechanism to wind up through the transmission structure, which improves the problems of inaccurate winding distance and uneven fabric force deformation caused by repeated start-stop or unexpected factors. For example, when the winding motor receives a rotation command, it can improve the deformation of the fabric caused by uneven fabric force due to high instantaneous acceleration; when the winding motor receives a stop command or stops unexpectedly, it reduces the winding distance error caused by inertia and other factors (especially when a certain winding length is accumulated, such as completing 100 meters of winding, the accumulated error is large), and prevents the fabric from being deformed due to pulling.

[0057] (2) Gear transmission has a constant instantaneous transmission ratio, but gear transmission has high precision requirements. After a period of use, the loss will aggravate the vibration, sliding, and even tooth skipping problems generated in the gear transmission process. The setting of the first adjustment shaft can buffer the effect of the above problems on the winding shaft, improve the problems of inaccurate winding distance, uneven force and deformation of fabrics. If the winding mechanism or the deceleration drive system suddenly fails, the setting of the first adjustment shaft can reduce the damage to each other between the winding mechanism and the deceleration drive system, extend the service life of the equipment, and thus reduce production costs and improve production efficiency.

[0058] (3) The first adjustment shaft and the winding shaft are driven by a sprocket chain, which can provide an accurate average transmission ratio during operation without elastic sliding, making it more reliable and efficient. However, after a period of use, the chain may stretch and other problems. Within a certain elongation range, the second adjustment shaft and the second adjustment shaft auxiliary parts can automatically achieve the function of tightening the adjustment chain by swinging, thereby ensuring the accuracy of the transmission, extending the service life of the chain, and reducing the failure rate of the equipment.

[0059] (4) The deceleration drive system in the utility model does not directly drive the guide roller for pulling the fabric, but pulls the fabric by rotating and winding the winding mechanism, thereby reducing problems such as pulling or deformation of the fabric in the pulling path.

[0060] (5) The transmission structure in the utility model has a wider range of application scenarios, and there is no requirement for the distance between the loom body and the winding mechanism. When the winding mechanism is set independently of the loom body, it is more convenient to roll up and down, and it is easy to adjust when quality problems occur. At the same time, the winding path is extended, and the fabric is fully flattened in the winding path, eliminating stress concentration and ensuring that the fabric does not deform.

[0061] like Figure 2 As shown, a friction plate 66, a clamping member 67, and a clamping nut 68 are also provided on the reel 62. The friction plate 66 is provided adjacent to the second sprocket 65, and is pressed against the second sprocket 65 through the clamping member 67 and the clamping nut 68. By providing the friction plate 66, a certain damping and buffering effect can be further played, the reeling error caused by factors such as inertia can be reduced, the reeling distance can be controlled more accurately, and the reeling effect and product quality can be improved. The thickness and number of the friction plate can be set according to the actual use situation. For example, the friction plate can be set to two or even more plates, but it will not affect the normal reeling of the second sprocket 65 driving the reel 62. The reel 62 is provided with a thread at the position of the clamping nut 68. When the friction plate 66 is worn, the clamping nut 68 can be rotated to ensure that the clamping member 67 always presses the friction plate 66.

[0062] like Figure 1 As shown, the upper surface of the first guide roller 21 is preferably set to be flush with the work surface of the loom body to achieve horizontal traction of the fabric 9 and achieve a better traction effect. In this embodiment, the first guide roller 21 is set at a fixed position on the first support structure 2. In other embodiments, the position of the first guide roller 21 in the upper and lower or left and right positions of the support structure or between the two side support structures can also be adjusted by setting an adjustment mechanism to achieve precise adjustment of the position of the first guide roller 21, so as to prevent fabric traction damage caused by improper position of the first guide roller 21 or lateral deviation of the fabric, resulting in uneven winding, fabric wrinkles and other quality problems.

[0063] like Figure 1As shown, the second guide roller 22 is located at the lower side of the first guide roller 21. The position of the second guide roller 22 can be adjusted according to actual needs through the first adjustment mechanism 24. The first adjustment mechanism 24 is symmetrically arranged on both sides of the first support structure 2. Figure 4 An enlarged schematic diagram of the first adjustment mechanism 24 is shown. Figure 4 As shown, the first adjustment mechanism 24 includes an adjustment module 241, an adjustment screw 242, an adjustment nut 243, and an adjustment spring 244. The upper and lower ends of the adjustment module 241 form a U-shaped groove, which is embedded in the slideway formed on the first supporting structure 2. One end of the adjustment screw 242 is connected to the adjustment module 241, and the other end passes through the first supporting structure 2 and is connected to the adjustment nut 243. The adjustment screw 242 is threadedly connected to the first supporting structure 2. The adjustment spring 244 is sleeved on the adjustment screw 242 and is located between the adjustment module 241 and the second supporting structure 2. The two ends of the second guide roller 22 are respectively connected to the adjustment modules 241 on both sides to adjust the position of the second guide roller 22. Its working principle is: in the production and use process, in order to ensure the relative position of the fabric 9 between the first guide roller 21 and the second guide roller 22, when there is a difference in the thickness and hardness of the fabric 9, the adjustment nut 243 is used to rotate the adjustment screw 242, thereby pushing the adjustment module 241 and the second guide roller 22 to move. The adjustment spring 244 is conducive to fine-tuning the position of the adjustment module 241. In the direction in which the second guide roller 22 moves with the adjustment module 241, distance measuring devices, such as a scale 245, are symmetrically arranged on both sides of the second support structure 2 to ensure the accuracy of the adjustment distance and the consistency of the positions on both sides. In this embodiment, the left and right positions of the second guide roller 22 on the support structure are adjustable, which can meet the tension requirements of fabrics of different thicknesses and hardnesses. In other embodiments, it can also be set to be adjustable at the upper and lower positions on the support structure or at the position between the two side support structures.

[0064] like Figure 1 As shown, the third guide roller 23 is arranged at the bottom of the first supporting structure 2, and the diameter of the third guide roller 23 is smaller than the first guide roller 21 and the second guide roller 22, so as to reduce the contact area between the fabric 9 and the third guide roller 23, thereby reducing the friction between the fabric and the guide roller and improving the fabric quality. Figure 5 This is the left side view of the winding device. Figure 6 Shows Figure 5 The enlarged schematic diagram of the second adjustment mechanism 25 is as shown in FIG. Figure 5 , Figure 6As shown, the position of the third guide roller 23 can be adjusted by the second adjustment mechanism 25. The second adjustment mechanism 25 is symmetrically arranged on both sides of the first support structure 2, and the second adjustment mechanism 25 includes a first adjustment seat 251, a second adjustment seat 252, an adjustment screw 253, and an adjustment hand wheel 254. The first adjustment seat 251 can be provided with one or more groups of adjustment slide rails 255 and adjustment sliders 256 arranged side by side, and the second adjustment seat 252 is connected to one or more groups of adjustment sliders 256 through a first adjustment connecting plate 257, so that it can slide relatively to the first adjustment seat 251. The two ends of the third guide roller 23 pass through the two sides of the first support structure 2 respectively, and are rotatably connected to the second adjustment seat 252 through a bearing. One end of the adjustment screw 253 contacts the second adjustment seat 252, and the other end passes through the second adjustment connecting plate 258 arranged on the first adjustment seat 251, and is fixedly connected to the adjustment hand wheel 254. The adjustment screw 253 is threadedly connected to the second adjustment connecting plate 258. Its working principle is that when the fabric 9 passing through the third guide roller 23 is laterally offset toward one side of the supporting structure, the adjustment hand wheel 254 on that side is rotated, thereby pushing the adjustment screw 253, the second adjustment seat 252, the first adjustment connecting plate 257, and the adjustment slider 256 to move along the adjustment slide rail 255 toward the other side of the supporting structure, thereby adjusting the position of the third guide roller 23, thereby correcting the position of the fabric 9 and improving the winding effect and product quality.

[0065] Figure 7 Shows Figure 5 The structural diagram of the edge detection mechanism is as follows: Figure 5 , Figure 7 As shown, an edge detection mechanism 26 is also provided between the second guide roller 22 and the third guide roller 23, including a detection connection seat 261, a detection connection rod 262, and a detection probe 263. One side of the detection connection seat 261 can be connected to the first supporting structure 2 by bolts, and the other side is connected to the detection connection rod 262. The other side of the detection connection rod 262 is connected to the detection probe 263, and the detection probe 263 can be rotated to any angle as needed. Its working principle is: the fabric 9 is pulled from the middle of the detection probe 263. When the fabric 9 deviates, the detection probe 263 picks up the position deviation signal of the fabric 9, and then transmits the position deviation signal to the controller (not shown in the figure). When the deviation range exceeds the preset value, the controller sends an alarm signal, and the staff adjusts the position of the third guide roller 23 according to the actual deviation, so as to correct the position of the fabric 9 and improve the winding effect and product quality.

[0066] In addition, if Figure 1As shown, the tension adjustment mechanism 4 includes a lower pressing shaft 41, an upper supporting shaft 42 and a lower pressing shaft 43, each of which is connected to the winding device chassis 1 through a bearing and can rotate with the fabric 9. A tension sensor 44 is arranged at the lower side of the upper supporting shaft 42. Its working principle is: during production, the pressure of the fabric 9 on the upper supporting shaft 42 will be fed back to the tension controller (not shown in the figure) through the tension sensor 44, and the tension controller can automatically adjust to meet the constant tension of the fabric 9 in the traction path, so as to avoid wrinkles or stretching deformation of the fabric 9 due to inappropriate tension.

[0067] like Figure 1 As shown, a traction roller 5 is also provided on the winding device chassis 1, and is located between the tension adjustment mechanism 4 and the winding mechanism 6. The traction roller 5 is connected to the winding device chassis 1 through an adjustable slider bearing seat 51, so that the height of the traction roller 5 is adjustable. When the fabric material, thickness, etc. are different, the angle at which the fabric enters the winding roller 61 can be adjusted by adjusting the height of the traction roller 5, so as to achieve a better winding effect.

[0068] Figure 8 FIG. 4 shows a schematic diagram of the structure of the paper placing mechanism. Figure 8 As shown, the paper placing mechanism 7 is arranged outside the traction path of the fabric 9, which is convenient for rolling up and down, and is not limited by the diameter of the backing paper roll. The paper placing mechanism 7 includes a paper placing rack 71 and a paper placing roller 72, and the paper placing rack 71 is fixedly connected with the bottom frame 1 of the winding device by bolts. A safety chuck 73 is arranged on the paper placing rack 71, which is used to place the paper placing roller 72. This method is used for quick and convenient rolling up and down. A backing paper adjustment mechanism is arranged on the paper placing rack 71 to adjust the position of the paper placing roller 72. The backing paper adjustment mechanism includes cross slides 711 and 712, a slide rail 713 and a slider 714. Cross slides 711 and 712 are arranged on one side of the paper placing rack 71, and the cross slide 711 is arranged below the cross slide 712, and the cross slide 712 is connected to the safety chuck 73. The front and rear position of the paper placing roller 72 on the paper placing rack 71 can be adjusted by adjusting the cross slide 712; a slide rail 713 and a slider 714 are arranged on the other side of the paper placing rack 71, and the slider 714 is connected to the safety chuck 73 through a slider connecting plate 715. The cross slide 711 cooperates with the slide rail 713 and the slider 714 to adjust the position of the paper placing roller 72 between the paper placing racks 71 on both sides. When the tension of the entire surface of the lining paper 10 is inconsistent, or when the relative position of the lining paper 10 and the fabric 9 deviates, these problems can be solved by fine-tuning the lining paper adjustment mechanism to improve the winding effect.

[0069] The paper unwinding roller 72 can be set as an air expansion roller. A magnetic powder brake 74 is set on one side of the paper unwinding roller 72 to ensure that the unwinding tension of the lining paper is controllable. Its working principle is: one end of the magnetic powder brake 74 is mechanically connected to the safety chuck 73, and the other side is connected to the magnetic powder controller (not shown in the figure) through a circuit. When the magnetic powder controller is in manual state, the lining paper 10 is pulled to the winding roller 61 and then adjusted to the automatic state. During use, the magnetic powder controller will automatically adjust the control parameters according to the production state, and transmit the signal to the magnetic powder brake 74 to realize automatic control of the paper unwinding tension. The overall height of the paper unwinding rack 71 is lower than the height of the winding rack 32, which ensures the angle of intersection between the lining paper 10 and the fabric 9, and avoids the fabric 9 from wrinkling, twisting and other undesirable phenomena due to uneven force; at the same time, its height must also meet the requirements of the roll diameter of the lining paper raw material. The lining paper 10 can use kraft lining paper, release lining paper and other papers with isolation and non-adhesive carbon fiber functions.

[0070] The working process of the winding device in this embodiment is as follows:

[0071] (1) The weft yarns are interwoven with the warp yarns between the heald frame and the work surface to form a fabric.

[0072] (2) Its working method is: every time one weft yarn is woven in (for example, 20 mm in width), the winding roller 61 rotates a corresponding distance (for example, 20 mm), thereby realizing the winding of the fabric.

[0073] (3) When the winding length of the fabric 9 reaches the expected length, the fabric 9 and the backing paper 10 are pasted together on the winding roller 61, and then the fabric 9 is cut at the tape pasting position, and the rolled fabric 9 is unloaded from the winding roller 61, completing the production of one roll of fabric.

[0074] Although the starting point of the present invention is to improve the winding effect of carbon fiber stretched tow woven fabrics, those skilled in the art will know after reading the present invention that the present invention can also be applied to the winding of other fiber fabrics with similar properties to carbon fiber fabrics.

[0075] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
