Description

Technical Field

[0001] The invention belongs to the field of braided fabric processing, and in particular relates to an automatic processing device for carbon fiber braided fabric. Background Art

[0002] In many fields such as aerospace, high-end sports equipment and automobile manufacturing, carbon fiber braids have become an indispensable key material due to their excellent properties such as high strength and low density. When processing carbon fiber braids, the spraying process is an extremely important part. By spraying specific coating materials, the performance of carbon fiber braids can be further improved, such as enhancing their wear resistance, corrosion resistance and improving their appearance.

[0003] However, the current carbon fiber woven fabric spraying process has obvious technical difficulties. Since carbon fiber woven fabric has a typical porous microstructure, this structural feature makes it very easy for the spray liquid used to quickly penetrate into the fabric during the spraying process. In the subsequent transmission process, the spray liquid that penetrates into the fabric will gradually accumulate on the lower surface of the carbon fiber woven fabric under the combined influence of gravity and other effects. In the subsequent processing and transmission process, the amount of spray liquid on the lower surface of the carbon fiber woven fabric will increase, which will not only cause uneven spraying on its surface, affecting the performance and quality of the product, but also cause waste of spray liquid.

[0004] In order to avoid the above technical problems, it is necessary to provide an automatic processing device for carbon fiber braids to overcome the above defects in the prior art. Summary of the invention

[0005] The object of the present invention is to provide an automatic processing device for carbon fiber braids to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: an automatic processing device for carbon fiber braids, comprising a processing machine frame, the processing machine frame is provided with two conveying rollers for conveying carbon fiber braids, a brush plate is installed in the processing machine frame, and positioning pressing rollers are installed at the conveying ports on both sides of the brush plate, and each of the positioning pressing rollers is provided with a plurality of pressing convex strips for pressing the surface of the carbon fiber braids; When the carbon fiber braid is conveyed between the two positioning and pressing rollers, the positioning and pressing rollers on both sides will press the surface of the carbon fiber braid through the pressing convex strips, so that the lower side of the carbon fiber braid can fully contact the surface of the brush plate, thereby enhancing the conveying friction force on the brush plate; The processing machine frame is provided with a spraying mechanism for spraying the transported carbon fiber braided fabric.

[0007] As a preferred embodiment, the spraying mechanism includes a liquid spray tank, which is connected to a nozzle via a delivery pipe, and a liquid pump for providing spraying power is provided on the delivery pipe. The liquid pump extracts the spray liquid in the liquid spray tank, delivers it to the nozzle through the delivery pipe, and sprays the surface of the delivered carbon fiber woven fabric.

[0008] As a preferred embodiment, the brush disc includes an outer disc frame, an inner brush ring and a central brush plate. The outer disc frame is fixedly arranged in a processing machine frame, the inner brush ring is rotatably arranged in the outer disc frame, the central brush plate is rotatably arranged in the inner brush ring, and a driving mechanism capable of driving the inner brush ring and the central brush plate to rotate in relative opposite directions is arranged in the processing machine frame.

[0009] As a preferred embodiment, the driving mechanism includes a rotating rod and a bevel gear transmission box, and one end of the rotating rod is fixedly arranged on the lower surface of the center brush plate.

[0010] As a preferred embodiment, the bottom end of the rotating rod is penetrated through the bevel gear transmission box, and the rotating rod is connected to the driven bevel gear at the bottom of the bevel gear transmission box, and the driven bevel gear at the top of the bevel gear transmission box is rotatably set on the rotating rod through a rotating sleeve.

[0011] As a preferred implementation scheme, the rotating sleeve is rotatably arranged on the top of the bevel gear transmission box, and its two sides are connected to the bottom of the inner brush ring through L-shaped connecting rods.

[0012] As a preferred implementation scheme, a driving bevel gear is installed in the bevel gear transmission box, the driving bevel gear is meshed with the two driven bevel gears, and a motor is installed on one side of the processing machine frame.

[0013] As a preferred implementation scheme, the motor is rotatably arranged on one side of the processing machine frame and the bevel gear transmission box through a driving shaft and is connected to the active bevel gear. When driven by the motor, the active bevel gear meshes with the two driven bevel gears to drive the inner brush ring and the center brush plate to rotate in opposite directions.

[0014] As a preferred embodiment, a plurality of brush blocks for brushing the lower surface of the carbon fiber braid are fixedly mounted on the inner brush ring and the central brush plate, and the brush blocks are hollow inside and provided with a plurality of stirring rods.

[0015] As a preferred embodiment, the brushing area of ​​the inner brush ring is the same as that of the brush block on the central brush plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the carbon fiber braid is conveyed by the conveying roller and passes through the spraying mechanism and the brush plate in sequence. During spraying, the spray liquid penetrates and accumulates on the lower surface of the braid. After reaching the brush plate, the positioning pressing roller makes the lower surface of the braid fully contact the brush plate through the pressing convex strips, thereby enhancing the conveying friction and stabilizing the conveying. At the same time, the friction of the brush plate causes the spray liquid to fall into the brush plate to form accumulated liquid, which can be subsequently added to the lower surface of the braid to achieve redistribution of the spray liquid, solve the problem of uneven spraying, improve product quality, and reduce waste of spray liquid.

[0017] In the present invention, a motor drives the active bevel gear, which drives the driven bevel gear to make the inner brush ring and the center brush plate rotate in opposite directions relative to each other. When the carbon fiber braid passes through the brush plate, the spray liquid accumulated on its lower surface is redistributed and coated, thereby solving the problem of uneven distribution of the spray liquid. Moreover, the lateral forces generated by the rotation of the inner brush ring and the center brush plate offset each other, thereby reducing the deviation and shaking of the braid during transportation and ensuring stable transportation.

[0018] In the present invention, the inner brush ring and the center brush plate rotate in opposite directions to drive the brush block to brush the lower surface of the woven fabric. The stirring rod in the brush block stirs the accumulated liquid in the brush disk to enhance its activity and make the spray liquid composition uniform. The brush block and the stirring rod use the centrifugal force of the brush disk rotation to control the spray liquid amount, so that the spray liquid is more evenly distributed in various areas of the brush disk, ensuring that the spraying effect is stable and consistent, improving the spraying effect of the equipment, and facilitating the processing of high-quality carbon fiber woven fabrics.

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] The following examples are used to illustrate the present invention, but they cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions. Simple improvements to the method of the present invention under the premise of the concept of the present invention belong to the scope of protection claimed in the present invention.

[0023] See also Figure 1-9 The present invention provides an automatic processing device for carbon fiber braids, comprising a processing machine frame 1, on which two conveying rollers 2 for conveying carbon fiber braids are arranged, a brush plate 3 is installed in the processing machine frame 1, and positioning pressing rollers 4 are installed at the conveying ports on both sides of the brush plate 3, and each positioning pressing roller 4 is installed with a plurality of pressing convex strips 5 for pressing the surface of the carbon fiber braids; When the carbon fiber braid passes between the two positioning and pressing rollers 4, the positioning and pressing rollers 4 on both sides press the surface of the carbon fiber braid through the pressing convex strips 5, so that the lower side of the carbon fiber braid can fully contact the surface of the brush plate 3, thereby enhancing the conveying friction force on the brush plate 3; The processing machine frame 1 is provided with a spraying mechanism 6 for spraying the conveyed carbon fiber braided fabric.

[0024] When the carbon fiber braid is conveyed under the drive of the conveying roller 2, it will pass through key components such as the spraying mechanism 6 and the brush plate 3 in sequence. The spraying mechanism 6 first sprays the carbon fiber braid. Due to the porous structure of the braid, the spray liquid will inevitably penetrate into the interior and accumulate on its lower surface. Then, when the carbon fiber braid is conveyed to the brush plate 3, the positioning and pressing roller 4 begins to play a key role. When the carbon fiber braid is conveyed between the two positioning and pressing rollers 4, the positioning and pressing rollers 4 on both sides will press its surface through the pressing convex strips 5, so that the lower side of the carbon fiber braid can fully contact the surface of the brush plate 3, which not only enhances its conveying friction to the brush plate 3, but also ensures that the braid is on the brush plate. 3, and more importantly, it optimizes the distribution of the spray liquid. Since the spray liquid accumulates on the lower surface of the carbon fiber braid, during the process of contact and relative movement with the surface of the brush disc 3, the spray liquid deposited on its lower surface will fall into the brush disc 3 due to the friction and scratch of the brush disc 3, so that a certain amount of liquid accumulation is formed in the brush disc 3. When the subsequent liquid accumulation at the bottom of the woven cloth is less, when it is transported through this brush disc 3, the accumulated liquid in the brush disc 3 can be supplemented to the lower surface of the braid, so as to realize the redistribution of the spray liquid, thereby effectively solving the problem of uneven spraying caused by uneven accumulation of the spray liquid on the lower surface of the braid, so that the carbon fiber braid can be sprayed more evenly, improving the performance and quality of the product, and reducing the waste of the spray liquid.

[0025] like Figure 3 As shown, the spraying mechanism 6 includes a spray tank 61, which is connected to a nozzle 64 via a delivery pipe 62. The delivery pipe 62 is provided with a liquid pump 63 for providing spraying power. The liquid pump 63 extracts the spray liquid in the spray tank 61, delivers it to the nozzle 64 through the delivery pipe 62, and sprays the surface of the delivered carbon fiber woven fabric.

[0026] like Figures 6 to 8 As shown, the brush disc 3 includes an outer disc frame 7, an inner brush ring 8 and a central brush plate 9. The outer disc frame 7 is fixedly arranged in the processing machine frame 1, the inner brush ring 8 is rotatably arranged in the outer disc frame 7, and the central brush plate 9 is rotatably arranged in the inner brush ring 8. A driving mechanism is arranged in the processing machine frame 1, which can drive the inner brush ring 8 and the central brush plate 9 to rotate in opposite directions.

[0027] like Figure 6 and Figure 7 As shown, the driving mechanism includes a rotating rod 10 and a bevel gear transmission box 11, and one end of the rotating rod 10 is fixedly arranged on the lower surface of the center brush plate 9.

[0028] like Figure 6 and Figure 7As shown, the bottom end of the rotating rod 10 is penetrated and set in the bevel gear transmission box 11, and the rotating rod 10 is connected to the driven bevel gear 12 at the bottom of the bevel gear transmission box 11, and the driven bevel gear 12 at the top of the bevel gear transmission box 11 is rotatably set on the rotating rod 10 through a rotating sleeve 13.

[0029] like Figure 6 and Figure 7 As shown, the rotating sleeve 13 is rotatably arranged on the top of the bevel gear transmission box 11 , and its two sides are connected to the bottom of the inner brush ring 8 through L-shaped connecting rods 14 .

[0030] like Figures 5 to 7 As shown, a driving bevel gear 15 is installed in the bevel gear transmission box 11 , and the driving bevel gear 15 is meshed with two driven bevel gears 12 . A motor 16 is installed on one side of the processing machine frame 1 .

[0031] like Figures 5 to 7 As shown, the motor 16 is rotatably arranged on one side of the processing machine frame 1 and the bevel gear transmission box 11 through the driving shaft 17 and is connected to the active bevel gear 15. Under the drive of the motor 16, the active bevel gear 15 will drive the meshing transmission of the two driven bevel gears 12 to drive the inner brush ring 8 and the center brush plate 9 to rotate in opposite directions.

[0032] The motor 16 transmits power to the active bevel gear 15 in the bevel gear transmission box 11 through the drive shaft 17. After the active bevel gear 15 rotates at high speed, it drives the two driven bevel gears 12 meshing with it, thereby causing the inner brush ring 8 and the center brush plate 9 to rotate in the opposite direction relative to each other. When the carbon fiber braid passes through the brush disc 3 driven by the conveying roller 2, the spray liquid that penetrates and accumulates on its lower surface will be redistributed and smeared under the action of the relative reverse rotation of the inner brush ring 8 and the center brush plate 9, which helps to adjust the originally unevenly accumulated spray liquid, thereby further improving the problem of uneven distribution of the spray liquid on the lower surface of the carbon fiber braid. In addition, the relative reverse rotation of the inner brush ring 8 and the center brush plate 9 offsets each other's influence on the conveying direction of the carbon fiber braid to a certain extent. Since the two rotate in opposite directions, when the lower surface of the carbon fiber braid is brushed, the lateral forces they generate offset each other, reducing the possibility of the braid being offset or shaking due to the rotation of the brush disc components during transportation, thereby ensuring that the carbon fiber braid can be transported more stably when passing through the brush disc 3.

[0033] like Figure 8 As shown, a plurality of brush blocks 18 for brushing the lower surface of the carbon fiber braid are fixedly mounted on the inner brush ring 8 and the central brush plate 9. The brush blocks 18 are hollow inside and are provided with a plurality of stirring rods 19.

[0034] When the inner brush ring 8 and the central brush plate 9 rotate in opposite directions relative to each other under the drive of the motor 16, the brush block 18 installed thereon will brush the lower surface of the carbon fiber braid synchronously. During the rotation and brushing process of the brush block 18, in conjunction with the mutual reverse rotation of the inner brush ring 8 and the central brush plate 9, the stirring rod 19 can mix and stir the spray liquid accumulated in the brush plate 3. With the continuous stirring of the stirring rod 19, the activity of the accumulated liquid in the brush plate 3 is significantly enhanced, and the spray liquid that may have been precipitated or unevenly distributed is fully mixed, making the composition of the spray liquid more uniform. In addition, during the rotation of the brush block 18 and the stirring rod 19, the centrifugal force of the rotation of the brush disc 3 is utilized to control the amount of spray liquid in the brush disc 3 to a certain extent. Under the influence of the centrifugal force, the spray liquid can be more evenly distributed in various areas of the brush disc 3, thereby avoiding excessive accumulation or insufficiency of the spray liquid in local areas, and ensuring the stability and consistency of the spraying effect. In summary, the spraying effect of the automatic processing equipment for carbon fiber braids is significantly improved by controlling the stirring, mixing and amount of the spray liquid, thereby providing strong support for the processing of high-quality carbon fiber braids.

[0035] like Fig. 9 As shown, the brushing areas of the inner brush ring 8 and the brush blocks 18 on the central brush plate 9 are the same.

[0036] The working principle and use process of the present invention are as follows: first, the power of the entire device is turned on, the motor 16 and the liquid pump 63 are started, and the liquid pump 63 starts to operate, extracts the spray liquid in the spray tank 61, and stably delivers it to the nozzle 64 through the delivery pipe 62. At this time, the delivery roller 2 operates synchronously, driving the carbon fiber braid to enter from one end of the device. When the carbon fiber braid moves below the nozzle 64, the nozzle 64 sprays the spray liquid to spray the surface of the carbon fiber braid. Since the carbon fiber braid has a porous structure, the spray liquid will penetrate into the interior during the spraying process and gradually accumulate on its lower surface under the action of gravity; As the carbon fiber braid continues to be transported forward and reaches the brush plate 3, when passing between the two positioning and pressing rollers 4, the positioning and pressing rollers 4 on both sides press the surface of the carbon fiber braid through the pressing convex strips 5, so that the lower side of the carbon fiber braid can be closely attached to the surface of the brush plate 3, effectively enhancing its conveying friction force on the brush plate 3, ensuring that the carbon fiber braid moves stably on the brush plate 3; At this time, the motor 16 transmits power to the active bevel gear 15 in the bevel gear transmission box 11 through the driving shaft 17. The active bevel gear 15 rotates at a high speed and meshes with the two driven bevel gears 12, and then drives the inner brush ring 8 to rotate through the rotating sleeve 13 and the L-shaped connecting rod 14 respectively, and drives the center brush plate 9 to perform relatively reverse brushing through the rotating rod 10. During the brushing process, the brush block 18 on the inner brush ring 8 and the center brush plate 9 vigorously brushes the lower surface of the carbon fiber braid. The brush block 18 is hollow inside and is provided with a stirring rod 19. While the brush block 18 rotates and brushes, the stirring rod 19 starts to mix and stir the spray accumulated in the brush plate 3 in conjunction with the reverse rotation of the inner brush ring 8 and the center brush plate 9. This stirring process significantly enhances the activity of the accumulated liquid in the brush plate 3, so that the spray that may have been precipitated or unevenly distributed is fully mixed, and the spray composition is more uniform. At the same time, during the rotation of the brush block 18 and the stirring rod 19, the centrifugal force generated by the rotation of the brush disc 3 is used to control the amount of spray liquid in the brush disc 3 to a certain extent. Under the influence of the centrifugal force, the spray liquid can be more evenly distributed in various areas of the brush disc 3, avoiding excessive accumulation or deficiency of the spray liquid in local areas. As the carbon fiber braid is continuously conveyed forward, after being processed by the brush disc 3, the excess accumulated spray liquid on the lower surface is automatically re-optimized and distributed, making the spray liquid distribution on the entire surface of the carbon fiber braid more even, thereby achieving high-quality and uniform spraying effects, ensuring product performance and quality, and improving production efficiency.
