AI Technical Summary
In the production equipment and preparation process of existing carbon fiber rolls, although the impregnated carbon fiber tow surface is cleaned, epoxy resin is still attached to the tow, affecting the winding effect, resulting in the carbon fiber tow being easily slipped and gathering together when wrapped with the core tube in a tight state, resulting in poor winding effect.
A production equipment for carbon fiber rollers is designed, including a guide adjustment mechanism and a thread groove. The carbon fiber tow is tension-adjusted through the guide adjustment mechanism to prevent sliding and gathering, and the friction between the core tube surface and the carbon fiber tow is increased through the thread groove to improve the winding effect.
By enhancing the friction between the core tube surface and the carbon fiber tow and improving tension adjustment, the winding effect of the carbon fiber tow is significantly improved, and the sliding and aggregation phenomenon is reduced, making the preparation of the carbon fiber roller more uniform and stable.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of the production of carbon fiber rollers, and specifically to a production device and a preparation process thereof for carbon fiber rollers. Background Art
[0002] On some production equipment, rollers are required to transport, wind up, and press materials. Generally, the rollers used are steel rollers, which are hollow inside. At the same time, in order to ensure that the steel rollers are not prone to bending during long-term use, the hollow steel rollers are required to have a certain wall thickness. However, this also makes the weight of the steel rollers relatively heavy. Therefore, some steel rollers are provided with a carbon fiber layer inside. Carbon fiber has a lighter weight and better strength. With its excellent performance, the carbon fiber roller is gradually replacing the traditional metal roller and becoming a key component in the transformation of the industrial field towards lightweight and high-performance. During the preparation of the carbon fiber roller, generally, carbon fiber is wound around a core tube to form a carbon fiber layer, and then post-treatment is carried out to form the final carbon fiber roller.
[0003] Before winding the carbon fiber tow around the core tube, it is necessary to impregnate the carbon fiber tow with epoxy resin. Through resin penetration, the composite of fiber and matrix can be realized, which can enhance the interfacial bonding, protect the fiber structure, and achieve load transfer, etc. The essence of impregnating the carbon fiber tow is to realize the synergistic strengthening of fiber and matrix through resin penetration to form a high-performance prepreg, which is an indispensable link in the manufacture of high-performance composite materials. The uncured epoxy resin is in a viscous liquid state. After impregnation, the carbon fiber tow will clean the excess epoxy resin on its surface, and then attach it to the surface of the core tube by winding. After that, post-treatment such as curing treatment and trimming is carried out to obtain the carbon fiber roller.
[0004] In the existing production equipment and preparation process of carbon fiber rollers, although the excess epoxy resin on the surface of the impregnated carbon fiber tow is cleaned, there are still many epoxy resins attached to the surface of the carbon fiber tow, which affects the winding effect. Especially when the carbon fiber tow is in a taut state, it is easy to have relative sliding when winding with the core tube, and in severe cases, the carbon fiber tow will gather together, resulting in a poor winding effect. Summary of the Invention
[0005] (I) Technical Problems to be Solved Aiming at the deficiencies of the prior art, the present invention provides a production device and a preparation process thereof for carbon fiber rollers, which solve the problem that although the excess epoxy resin on the surface of the impregnated carbon fiber tow is cleaned, there are still many epoxy resins attached to the surface of the carbon fiber tow, which affects the winding effect. Especially when the carbon fiber tow is in a taut state, it is easy to have relative sliding when winding with the core tube, and in severe cases, the carbon fiber tow will gather together, resulting in a poor winding effect.
[0006] (2) Technical Solution To achieve the above object, the present invention is implemented through the following technical solutions: A production device for a carbon fiber roller includes a base. On one side of the top of the base, a tow plate fixing mechanism is provided. On the top of the base, a guide wheel group is provided. There are two guide wheel groups. On the other side of the top of the base, a guide adjustment mechanism is provided. One side of the base is fixedly connected to a mounting plate. On the top of the mounting plate, a clamping mechanism is provided. Inside the clamping mechanism, a carbon fiber roller body is provided; The guide adjustment mechanism includes a fixed frame. The fixed frame is fixedly connected to the top of the base. On both sides of the bottom of the fixed frame, first elastic telescopic rods are provided. The bottom ends of the two first elastic telescopic rods are jointly fixedly connected to a rectangular frame. Inside the rectangular frame, a guide roller assembly is provided. Through the setting of the first elastic telescopic rods and the rectangular frame, the tension of the carbon fiber tow can be adjusted as a whole, preventing the carbon fiber tow from being too tight and adhering to epoxy resin and sliding on the surface of the core tube, and then gathering together during winding. Or when the carbon fiber tow is too loose, the winding between the core tube and the carbon fiber tow is not tight, and then being too tight or too loose makes the winding effect poor. Through the first elastic telescopic rod, the tension of the overall carbon fiber tow can be adjusted, and through the second elastic telescopic rod, the tension of the small bundle of carbon fiber tows between each guide roller assembly can be adjusted, improving the accuracy of tension adjustment; The carbon fiber roller body includes a core tube. Thread grooves are provided on the surface of the core tube. The two ends of the core tube are fixedly connected to rotating shafts. One end of the rotating shaft is provided with a limit groove. Through the setting of the limit groove and the limit block, relative sliding between the clamping block and the rotating shaft can be prevented, thereby ensuring the stability of the core tube during rotation.
[0007] Preferably, the guide adjustment mechanism further includes an electronic slide rail. The top ends of the two first elastic telescopic rods are jointly fixedly connected to a slider. The slider is slidably connected inside the electronic slide rail. By moving the slider in the electronic slide rail, the inclination angle between the carbon fiber tow and the core tube can be changed, and thus the winding angle can be adjusted as needed, making it more flexible and variable during use.
[0008] Preferably, the guide roller assembly includes second elastic telescopic rods. There are two second elastic telescopic rods, and the two second elastic telescopic rods are fixedly connected to the inner side of the rectangular frame and are symmetrically distributed. One end of each second elastic telescopic rod is fixedly connected with a guide wheel, and a baffle is fixedly connected to the side of the guide wheel. Anti-slip guide grooves are formed on the surface of the guide wheel. The evenly divided carbon fiber tows are respectively placed between the upper and lower guide wheels, and then the baffle is used to prevent the carbon fiber tows from slipping out of the side of the guide wheel. The anti-slip guide grooves can evenly distribute the carbon fiber tows on the surface of the guide wheel, preventing them from sliding and aggregating due to the action of epoxy resin, so that the effect of winding the carbon fiber tows on the core tube in the later stage is more uniform and the winding effect is improved.
[0009] Preferably, the carbon fiber roller body further includes a carbon fiber tube. The carbon fiber tube is sleeved outside the core tube. A fixed end is coaxially sleeved on the surface of the rotating shaft. A first threaded hole is formed between the fixed end and the core tube, and a second threaded hole is formed between the fixed end and the carbon fiber tube. Bolts are threadedly connected inside both the first threaded hole and the second threaded hole. Through the settings of the first threaded hole, the second threaded hole and the bolts, relative sliding between the carbon fiber tube and the core tube can be prevented, thereby improving the overall stability of the carbon fiber roller body.
[0010] Preferably, the tow reel fixing mechanism includes side plates. The side plates are fixedly connected to the top of the base. A storage rack is rotatably connected to the front of the side plates. A PLC controller is fixedly connected to one side of the front of the side plates. The side plates are used to install and fix the PLC controller and the storage rack. The PLC controller can control the whole equipment, and the storage rack can be used to place and fix the carbon fiber tow reel.
[0011] Preferably, the tow reel fixing mechanism further includes a moving groove. A moving plate is slidably connected inside the moving groove. Two pulleys are fixedly installed at the bottom sides of the moving plate, and the pulleys are in rolling connection with the inside of the moving groove. An electric telescopic rod is fixedly connected between the side wall of the moving groove and the moving plate. A slot is formed on the back of the moving plate, and one end of the storage rack is inserted into the slot. Start the electric telescopic rod to drive the moving plate to separate from one end of the storage rack, so as to facilitate inserting the carbon fiber tow reel from this end for fixing. Then start the electric telescopic rod to drive the moving plate back to its original position, so that one end of the storage rack is inserted into the slot to prevent the carbon fiber tow reel from slipping off from this end. The pulleys are used to reduce the resistance between the moving plate and the moving groove, making the moving plate move more smoothly and reducing the wear degree of the equipment, thus prolonging the service life of the equipment.
[0012] Preferably, the clamping mechanism includes a sliding groove opened at the top of the mounting plate. The two sides of the top of the sliding groove are slidably connected with moving seats. The inner sides of the two moving seats are rotatably connected with clamping blocks. The inside of the clamping block is fixedly connected with a limiting block, and the limiting block is inserted into the limiting groove. One side of one of the moving seats is fixedly installed with a first motor, and the output end of the first motor is fixedly connected with one side of the clamping block.
[0013] Preferably, a second motor is fixedly installed on the front surface of the mounting plate. The output end of the second motor passes through the mounting plate and is fixedly connected with a bidirectional lead screw. The bidirectional lead screw is rotatably connected inside the sliding groove, and the two moving seats are threadedly connected with the bidirectional lead screw.
[0014] A preparation process of a carbon fiber roller includes the following steps: S1. The core tube and the rotating shaft as a whole are manufactured by die forging. The surface of the core tube is cut with thread grooves, limiting grooves and first threaded holes by a laser cutting machine, and the surface of the core tube is cut by the laser cutting machine according to the pre-set programming and shape to cut out the thread grooves, which are used to increase the resistance when the carbon fiber tow is wound around the core tube, preventing the un-cured epoxy resin from sliding between the core tube and the core tube, resulting in a poor winding effect. S2. The core tube is fixed in the clamping mechanism, the soaked carbon fiber tow reel is fixed in the tow reel fixing mechanism, and its output end passes through the guide wheel group and the guide adjustment mechanism in sequence, and finally is wound around the surface of the core tube. The winding of the carbon fiber tow on the surface of the core tube is realized by the clamping rotation of the clamping mechanism to obtain a carbon fiber tube. The evenly divided carbon fiber tows are respectively placed between the upper and lower guide wheels, and then the carbon fiber tows are prevented from slipping out of the side of the guide wheels by the baffle. The setting of the anti-slip guide groove can make the carbon fiber tows be evenly distributed on the surface of the guide wheels, preventing them from sliding and aggregating together due to the action of the epoxy resin, so that the winding effect of the core tube winding the carbon fiber tows in the later stage is more uniform, improving the winding effect. Through the setting of the first elastic telescopic rod and the rectangular frame, the tension of the carbon fiber tows can be adjusted as a whole, preventing the carbon fiber tows from being too tight and attached with epoxy resin and sliding on the surface of the core tube, and then aggregating together during winding, or when the carbon fiber tows are too loose, the winding between the core tube and the carbon fiber tows is not tight, and then being too tight or too loose resulting in a poor winding effect. The first elastic telescopic rod can adjust the tension of the whole carbon fiber tow, and the second elastic telescopic rod can adjust the tension of the small bundles of carbon fiber tows between each guide roller assembly, improving the accuracy of tension adjustment. S3. Remove the core tube wrapped with carbon fiber tows and perform a curing treatment. Then, use a laser cutting machine to cut off the excess carbon fiber tows at both ends of the carbon fiber tube, and use the laser cutting machine to engrave second threaded holes at both ends of the carbon fiber tube. S4. Obtain the fixed end through molding. Use a laser cutting machine to engrave a first threaded hole and a second threaded hole on the surface of the fixed end that are adapted to the core tube and the carbon fiber tube. Through the settings of the first threaded hole, the second threaded hole, and the bolt, relative sliding between the carbon fiber tube and the core tube can be prevented, thereby improving the overall stability of the carbon fiber roller body. S5. Pass the fixed end through the rotating shaft and align the first threaded hole and the second threaded hole with the first threaded hole on the core tube and the second threaded hole on the carbon fiber tube respectively. Then, fix the fixed end to the core tube and the carbon fiber tube respectively through the bolt to obtain a complete carbon fiber roller body.
[0015] (III) Beneficial effects The present invention provides a production device and a preparation process of a carbon fiber roller. It has the following beneficial effects: (I). In the production device and the preparation process of the carbon fiber roller, through the combined setting of the guiding and adjusting mechanism and the threaded groove, the friction force between the surface of the core tube and the carbon fiber tows attached with epoxy resin can be increased, thereby reducing the occurrence of sliding between the carbon fiber tows and the core tube, improving the winding effect of the carbon fiber tows. And through the guiding and adjusting mechanism, the carbon fiber tows can be evenly guided onto the surface of the core tube, reducing the possibility of aggregation due to sliding caused by the action of epoxy resin, so that when the core tube is wound with carbon fiber tows, it is more uniform, and the winding thickness is also more uniform, improving the winding effect.
[0016] (II).

Through the first elastic telescopic rod, the tension of the whole carbon fiber tows can be adjusted, and through the second elastic telescopic rod, the tension of the small bundles of carbon fiber tows between each guide roller assembly can be adjusted, improving the accuracy of tension adjustment.
[0017] (3).

First, insert the limiting groove 74 on one of the rotating shafts 73 into the limiting groove 74 on one of the clamping blocks 63. Then start the second motor 66 to drive the bidirectional lead screw 67 to rotate. The rotation of the bidirectional lead screw 67 drives the two moving seats 62 to move relatively until the two moving seats 62 gradually approach. At this time, align the limiting groove 74 on the other side with the limiting block 64 and insert it until the two clamping blocks 63 fix the core tube 71. When winding the carbon fiber tow on the surface of the core tube 71, start the first motor 65 to drive one of the clamping blocks 63 to rotate. Then the core tube 71 rotates between the two clamping blocks 63 and continuously winds the carbon fiber until the surface of the core tube 71 is wound with carbon fiber.
[0032] A preparation process of a carbon fiber roller includes the following steps: S1. The core tube 71 and the rotating shaft 73 are integrally manufactured by die forging. The surface of the core tube 71 is cut with thread grooves 72, limit grooves 74 and first threaded holes 77 by a laser cutting machine. The metal blank is heated and melted and then introduced into a mold for cooling and shaping. After that, the prototype of the core tube 71 is taken out, and then the burrs of the prototype of the core tube 71 are removed and polished. After that, heat treatment is carried out to enhance its mechanical properties. Finally, the core tube 71 and the rotating shaft 73 as a whole are obtained. The surface of the core tube 71 is cleaned to prevent dirt from remaining on the surface. According to the required winding angle, the programming of the inclined angle spiral groove is realized through the numerical control system, and the surface of the core tube 71 is cut by the laser cutting machine according to the pre-set programming and shape, and the thread grooves 72 are cut, which are used to increase the resistance when the carbon fiber tow is wound around the core tube 71, prevent the uncured epoxy resin from sliding between the core tube 71 and cause poor winding effect. The cutting depth is about 0.2 mm. Similarly, the first thread grooves 72 are cut at both ends of the core tube 71 by the laser cutting machine, and the limit grooves 74 are cut at the end face of the rotating shaft 73. The cut core tube 71 and the rotating shaft 73 are waiting for standby; S2. The core tube 71 is fixed in the clamping mechanism 6, the soaked carbon fiber tow spool is fixed in the tow spool fixing mechanism 2, and its output end passes through the guide wheel group 3 and the guide adjustment mechanism 4 in sequence, and finally winds around the surface of the core tube 71. The winding of the carbon fiber tow on the surface of the core tube 71 is realized by the clamping rotation of the clamping mechanism 6 to obtain the carbon fiber tube 75. The core tube 71 and the rotating shaft 73 with the cut and processed holes and grooves are fixed by the clamping mechanism 6. When fixing, first insert the limit groove 74 on one rotating shaft 73 into the limit groove 74 on one of the clamping blocks 63, and then start the second motor 66 to drive the bidirectional lead screw 67 to rotate. The rotation of the bidirectional lead screw 67 drives the moving seats 62 on both sides to move relatively until the two moving seats 62 gradually approach. At this time, align the limit groove 74 on the other side with the limit block 64 and insert it until the two clamping blocks 63 fix the core tube 71. When the soaked carbon fiber tow spool is fixed in the tow spool fixing mechanism 2, the carbon fiber tow spool is inserted and fixed from the end of the storage rack 22. Start the electric telescopic rod 27 to drive the moving plate 25 to move and insert one end of the storage rack 22 into the inside of the slot 28, so that the carbon fiber tow spool is fixed. Then, the carbon fiber tow on the spool passes through the two guide wheel groups 3 and the guide adjustment mechanism 4 in sequence, and finally winds around the surface of the core tube 71. And start the electronic slide rail 45 to drive the slider 46 to move, so that the rectangular frame 43 drives the carbon fiber tow to form an inclined angle with the core tube 71 until it is parallel to the inclined angle on the surface of the core tube 71. After that, start the first motor 65 to drive the clamping block 63 and the inner core tube 71 to rotate, so that the rotating core tube 71 can wind the carbon fiber tow on its surface until it winds to the required thickness; S3. Remove the core tube 71 wrapped with carbon fiber tows and perform a curing treatment. Then, use a laser cutting machine to cut off the excess carbon fiber tows at both ends of the carbon fiber tube 75, and use the laser cutting machine to engrave second threaded holes 78 at both ends of the carbon fiber tube 75. During the curing treatment, cure the epoxy resin by means of normal temperature cooling or heating, which improves strength, hardness, chemical corrosion resistance, electrical insulation, etc., and makes the carbon fiber tows firmly bonded to the epoxy resin. Then, use a laser cutting machine to cut off the excess parts at both ends of the carbon fiber tube 75, and then use the laser cutting machine to engrave second threaded holes 78 at both ends of the carbon fiber tube 75. The multiple engraved second threaded holes 78 are arranged concentrically with the multiple first threaded holes 77. S4. Obtain the fixed end 76 through molding. Use a laser cutting machine to engrave first threaded holes 77 and second threaded holes 78 on the surface of the fixed end 76 that are adapted to the core tube 71 and the carbon fiber tube 75. Select a metal blank same as the core tube 71 to melt, and then pour the molten metal into a mold to cool and solidify. After that, demold to obtain the prototype of the fixed end 76. Then, use a laser cutting machine to cut out the first threaded holes 77 and the second threaded holes 78 on the surface of the fixed end 76. The first threaded holes 77 and the second threaded holes 78 can coincide with the first threaded holes 77 on the core tube 71 and the second threaded holes 78 on the carbon fiber tube 75. S5. Pass the fixed end 76 through the rotating shaft 73 and align the first threaded holes 77 and the second threaded holes 78 with the first threaded holes 77 on the core tube 71 and the second threaded holes 78 on the carbon fiber tube 75 respectively. Then, fix the fixed end 76 to the core tube 71 and the carbon fiber tube 75 respectively through bolts 79 to obtain the complete carbon fiber roller body 7. Pass the fixed end 76 through the rotating shaft 73 and fit it to both ends of the core tube 71, so that the first threaded holes 77 and the second threaded holes 78 on the fixed end 76 respectively align and coincide with the first threaded holes 77 on the core tube 71 and the second threaded holes 78 on the carbon fiber tube 75. Fix the first threaded holes 77 and the second threaded holes 78 through bolts 79, so that the fixed end 76 is fixed to the core tube 71 and the carbon fiber tube 75, and then obtain the final carbon fiber roller body 7.
[0033] During operation, the core tube 71 is adjusted and fixed according to its size by the clamping mechanism 6. Then, the carbon fiber tow spool soaked with epoxy resin is fixed on the tow spool fixing mechanism 2. After that, the carbon fiber tows on the tow spool are sequentially guided through two sets of guide wheels 3, and then the carbon fiber tows are passed through the guiding and adjusting mechanism 4. Finally, the carbon fiber tows are wound around the surface of the core tube 71. The power in the clamping mechanism 6 is used to make the carbon fiber roller body 7 rotate and wind the carbon fiber tows. The wound carbon fiber roller body 7 is removed and cured. After curing, the excess parts of the two ends of the carbon fiber tube 75 extending beyond the core tube 71 are cut off by a laser cutting machine. Then, the laser cutting machine is used to engrave the first threaded holes 77 and the second threaded holes 78 at the two ends of the core tube 71 and the carbon fiber tube 75 respectively. The corresponding first threaded holes 77 and the second threaded holes 78 are engraved on the fixed end 76 by a laser engraving machine. Then, the fixed end 76 is passed through the rotating shaft 73 and bolted to the core tube 71 and the carbon fiber tube 75 with bolts 79. Through the settings of the first threaded holes 77, the second threaded holes 78 and the bolts 79, relative sliding between the carbon fiber tube 75 and the core tube 71 can be prevented, thereby improving the overall stability of the carbon fiber roller body 7; When fixing the core tube 71 by the clamping mechanism 6, first insert the limiting groove 74 on one rotating shaft 73 into the limiting groove 74 on one of the clamping blocks 63. Then start the second motor 66 to drive the bidirectional lead screw 67 to rotate. The rotation of the bidirectional lead screw 67 drives the moving seats 62 on both sides to move relatively until the two moving seats 62 gradually approach. At this time, align and insert the limiting groove 74 on the other side with the limiting block 64 until the two clamping blocks 63 fix the core tube 71. When winding the carbon fiber tows on the surface of the core tube 71, start the first motor 65 to drive one of the clamping blocks 63 to rotate. Then the core tube 71 rotates between the two clamping blocks 63 and continuously winds the carbon fiber until the surface of the core tube 71 is wound with carbon fiber tows; When fixing the carbon fiber tow spool soaked with epoxy resin on the tow spool fixing mechanism 2, start the electric telescopic rod 27 to drive the moving plate 25 to disengage from one end of the storage rack 22, so as to facilitate inserting the carbon fiber tow spool through this end for fixing. Then start the electric telescopic rod 27 to drive the moving plate 25 back to its original position, so that one end of the storage rack 22 is inserted into the inside of the slot 28 to prevent the carbon fiber tow spool from slipping off from this end. The role of the pulley 26 is used to reduce the resistance between the moving plate 25 and the moving groove 24, making the movement of the moving plate 25 smoother and capable of reducing the wear of the equipment, thereby extending the service life of the equipment; When the guiding and adjusting mechanism 4 guides and adjusts the carbon fiber tow, the evenly divided carbon fiber tows are respectively placed between the upper and lower guide wheels 442, and then the baffle 443 is used to prevent the carbon fiber tow from slipping out of the side of the guide wheel 442. The setting of the anti-slip guide groove 444 enables the carbon fiber tow to be evenly distributed on the surface of the guide wheel 442, preventing it from sliding and aggregating due to the action of epoxy resin. As a result, when the core tube 71 winds the carbon fiber tow later, it is more uniform, improving the winding effect. Through the setting of the first elastic telescopic rod 42 and the rectangular frame 43, the tension of the carbon fiber tow can be adjusted as a whole, preventing the carbon fiber tow from being too tight and attached with epoxy resin and sliding on the surface of the core tube 71, and then aggregating together during winding. Or when the carbon fiber tow is too loose, there will be insufficient winding between the core tube 71 and the carbon fiber tow, and being too tight or too loose will result in a poor winding effect. Through the first elastic telescopic rod 42, the tension of the whole carbon fiber tow can be adjusted, and through the second elastic telescopic rod 441, the tension of the small bundles of carbon fiber tows between each guide roller assembly 44 can be adjusted, improving the accuracy of tension adjustment. By moving the slider 46 in the electronic slide rail 45, the inclination angle between the carbon fiber tow and the core tube 71 can be changed, and thus the winding angle can be adjusted as needed, making it more flexible and variable during use. As Figures 5-6 described, it is the different moving positions of the rectangular frame 43, which results in different angles formed between the carbon fiber tow and the core tube 71.
