Description

Technical Field

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

[0002] Carbon fiber braids, with their high strength and low density, have become an indispensable key material in numerous fields, including aerospace, high-end sports equipment, and automotive manufacturing. Spray coating is a crucial step in the processing of carbon fiber braids. By applying specific coating materials, the performance of the carbon fiber braids can be further enhanced, such as increasing their wear and corrosion resistance and improving their appearance.

[0003] However, the current spray coating process for carbon fiber fabrics presents significant technical challenges. Due to the typical porous microstructure of carbon fiber fabrics, this structural feature allows the spray liquid used during the spray coating process to quickly penetrate into the fabric. During the subsequent transport process, this spray liquid, under the combined influence of gravity and other factors, will gradually accumulate on the lower surface of the carbon fiber fabric. This will increase the amount of spray liquid on the lower surface of the carbon fiber fabric during subsequent processing and transport. This will not only lead to uneven spraying on the surface, affecting product performance and quality, but also result in 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 solution: an automatic processing device for carbon fiber braids, comprising a processing machine frame, the processing machine frame being provided with two conveying rollers for conveying carbon fiber braids, a brush plate being installed in the processing machine frame, and positioning pressing rollers being installed at the conveying ports on both sides of the brush plate, each of the positioning pressing rollers being provided with a plurality of pressing ridges for pressing the surface of the carbon fiber braids;

[0007] When the carbon fiber braid is conveyed between the two positioning and pressing rollers, the positioning and pressing rollers on both sides press the surface of the carbon fiber braid through the pressing ribs, so that the lower side of the carbon fiber braid can fully contact the brush plate surface, thereby enhancing the conveying friction of the carbon fiber braid on the brush plate;

[0008] The processing machine frame is provided with a spraying mechanism for spraying the conveyed carbon fiber braided fabric.

[0009] As a preferred embodiment, the spraying mechanism includes a liquid spray tank, which is connected to a nozzle through a delivery pipe. The delivery pipe is provided with a liquid pump that provides spraying power. 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.

[0010] 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 the processing machine frame, the inner brush ring is rotatably arranged in the outer disc frame, and the central brush plate is rotatably arranged in the inner brush ring. A driving mechanism that can drive the inner brush ring and the central brush plate to rotate in relative opposite directions is provided in the processing machine frame.

[0011] 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 central brush plate.

[0012] As a preferred embodiment, the bottom end of the rotating rod is set 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 above the bevel gear transmission box is rotatably set on the rotating rod through a rotating sleeve.

[0013] As a preferred embodiment, 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.

[0014] As a preferred embodiment, a driving bevel gear is installed in the bevel gear transmission box, the driving bevel gear is engaged with the two driven bevel gears, and a motor is installed on one side of the processing machine frame.

[0015] As a preferred embodiment, the motor is rotatably arranged on one side of the processing machine frame and the bevel gear transmission box through a drive shaft and is connected to the active bevel gear. Under the drive of the motor, the active bevel gear will mesh with the two driven bevel gears to drive the inner brush ring and the center brush plate to rotate in opposite directions.

[0016] 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. The brush blocks are hollow inside and are provided with a plurality of stirring rods.

[0017] 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.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In this invention, the carbon fiber braid is conveyed via a conveyor roller, passing through a spray mechanism and a brush plate in sequence. During spraying, the spray liquid penetrates the lower surface of the braid and accumulates. Once it reaches the brush plate, the positioning pressing roller, through its pressing ribs, ensures that the lower surface of the braid fully contacts the brush plate, enhancing conveying friction and stabilizing delivery. Simultaneously, friction from the brush plate causes the spray liquid to fall into the brush plate, forming an accumulation of liquid that can subsequently be replenished on the lower surface of the braid, achieving redistribution of the spray liquid, solving the problem of uneven spraying, improving product quality, and reducing spray liquid waste.

[0020] In the present invention, the 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, 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, reducing the deviation and shaking of the braided fabric during transportation and ensuring stable transportation.

[0021] In the present invention, the inner brush ring and the central 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 disc, thereby enhancing its activity and making the spray composition uniform. The brush block and the stirring rod use the centrifugal force of the brush disc rotation to control the spray amount, so that the spray is more evenly distributed in various areas of the brush disc, ensuring stable and consistent spraying effects, improving the spraying effect of the equipment, and facilitating the processing of high-quality carbon fiber woven fabrics.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] The following examples are intended to illustrate the present invention but are not intended to limit the scope of protection of the present invention. The conditions in the examples may be further adjusted according to specific conditions. Simple improvements to the method of the present invention within the scope of the present invention are also within the scope of protection claimed in the present invention.

[0034] 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 are disposed two conveying rollers 2 for conveying carbon fiber braids, a brush plate 3 is installed in the processing machine frame 1, and positioning and pressing rollers 4 are installed at the conveying ports on both sides of the brush plate 3, and each positioning and pressing roller 4 is equipped with a plurality of pressing ridges 5 for pressing the surface of the carbon fiber braids;

[0035] 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 ribs 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;

[0036] The processing machine frame 1 is provided with a spraying mechanism 6 for spraying the conveyed carbon fiber braided fabric.

[0037] When the carbon fiber braid is conveyed by the conveying roller 2, it will pass through key components such as the spraying mechanism 6 and the brush plate 3 in turn. 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 ridges 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 on 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 of the brush disc 3, so that a certain amount of liquid accumulation is formed in the brush disc 3. When the liquid accumulation at the bottom of the subsequent braided 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, realizing 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, allowing the carbon fiber braid to be sprayed more evenly, improving the performance and quality of the product, and reducing the waste of spray liquid.

[0038] like Figure 3 As shown, the spraying mechanism 6 includes a liquid spray tank 61, which is connected to a nozzle 64 through a delivery pipe 62. A liquid pump 63 for providing spraying power is provided on the delivery pipe 62. The liquid pump 63 extracts the spray liquid in the liquid 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.

[0039] 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 that can drive the inner brush ring 8 and the central brush plate 9 to rotate in relative opposite directions is provided in the processing machine frame 1.

[0040] 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 .

[0041] like Figure 6 and Figure 7As shown, the bottom end of the rotating rod 10 is set through 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 above the bevel gear transmission box 11 is rotatably set on the rotating rod 10 through the rotating sleeve 13.

[0042] 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.

[0043] 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 .

[0044] 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 drive shaft 17 and is connected to the active bevel gear 15. Under the drive of the motor 16, the active bevel gear 15 will mesh with the two driven bevel gears 12 to drive the inner brush ring 8 and the center brush plate 9 to rotate in opposite directions.

[0045] 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 relative opposite directions. 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 brushing operation is performed on the lower surface of the carbon fiber braid, 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, and ensuring that the carbon fiber braid can be conveyed more stably when passing through the brush disc 3.

[0046] 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.

[0047] When the inner brush ring 8 and the center brush plate 9 rotate in opposite directions relative to each other under the drive of the motor 16, the brush block 18 installed on them will synchronously brush the lower surface of the carbon fiber braid. In the process of the brush block 18 rotating and brushing, in conjunction with the mutual opposite rotation of the inner brush ring 8 and the center brush plate 9, the stirring rod 19 can mix and stir the spray accumulated in the brush disc 3. With the continuous stirring of the stirring rod 19, the activity of the accumulated liquid in the brush disc 3 is significantly enhanced, and the spray that may have been precipitated or unevenly distributed is fully mixed, making the composition of the spray more uniform. In addition, during the rotation process, the brush block 18 and the stirring rod 19 utilize the centrifugal force of the rotation of the brush disc 3 to control the amount of spray liquid in the brush disc 3. Under the influence of 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, and ensuring the stability and consistency of the spraying effect. In summary, through the stirring, mixing and amount control of the spray liquid, the spraying effect of the automatic processing equipment for carbon fiber braids is significantly improved, providing strong support for the processing of high-quality carbon fiber braids.

[0048] like Figure 9 As shown, the brushing area of ​​the inner brush ring 8 and the brush block 18 on the central brush plate 9 is the same.

[0049] The working principle and use process of the present invention are as follows: first, turn on the power of the entire device, start the motor 16 and the liquid pump 63, and the liquid pump 63 starts to operate, extracting the spray liquid in the spray tank 61 and stably delivering it to the nozzle 64 through the delivery pipe 62. At this time, the delivery roller 2 runs 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. Due to the porous structure of the carbon fiber braid, the spray liquid will penetrate into the interior during the spraying process and gradually accumulate on its lower surface under the action of gravity;

[0050] As the carbon fiber braid continues to be transported forward and reaches the brush plate 3, when it 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 ribs 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 on the brush plate 3, ensuring that the carbon fiber braid moves stably on the brush plate 3;

[0051] At this time, the motor 16 transmits power to the active bevel gear 15 in the bevel gear transmission box 11 through the drive 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, and drives the center brush plate 9 to perform relative reverse brushing through the rotating rod 10. During the brushing process, the brush blocks 18 on the inner brush ring 8 and the center brush plate 9 vigorously brush 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 accumulated spray liquid in the brush disc 3 in conjunction with the mutual 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 disc 3, so that the spray liquid that may have been precipitated or unevenly distributed is fully mixed, and the spray liquid composition is more uniform and consistent;

[0052] At the same time, during the rotation process, the brush block 18 and the stirring rod 19 utilize the centrifugal force generated by the rotation of the brush disc 3 to control the amount of spray liquid in the brush disc 3 to a certain extent. Under the influence of centrifugal force, the spray liquid can be more evenly distributed in various areas of the brush disc 3, avoiding excessive accumulation or insufficiency 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 uniform, thereby achieving high-quality and uniform spraying effects, ensuring product performance and quality, and improving production efficiency.
