Description

Technical Field

[0001] The present application relates to the technical field of carbon fiber cloth processing, and in particular to a device and method for drying the surface of a carbon fiber cloth. Background Art

[0002] The surface of carbon fiber cloth is a non-woven carbon fiber felt made by wet molding after evacuating and dispersing carbon fiber chopped strands. During the production process, it undergoes special process treatment to make the carbon fiber very evenly distributed in the felt body, ensuring the consistency of material properties. This uniform fiber distribution makes the performance difference of the carbon fiber cloth surface in all directions smaller, and can better adapt to stress in different directions.

[0003] The existing method for preparing carbon fiber cloth is generally to soak the carbon fiber cloth in slurry and then transfer it to a drying area for drying. The overall preparation efficiency is low and the cost is high. Summary of the Invention

[0004] The present application provides a carbon fiber cloth surface sizing and drying device and method, which can realize continuous sizing and continuous drying of carbon fiber cloth, with uniform sizing and high drying efficiency, flexible and convenient operation, and can effectively improve work efficiency, reduce production costs, and is practical.

[0005] The embodiment of the present application is implemented as follows:

[0006] In a first aspect, the present application provides an example of a carbon fiber cloth surface sizing and drying device, which includes: a frame, a sizing mechanism, and a drying mechanism.

[0007] The sizing mechanism includes two sizing parts arranged on the frame, which are arranged at intervals along the direction of gravity to form a first gap for the carbon fiber cloth to pass through. The sizing part has a liquid storage cavity and multiple liquid outlets connected to the liquid storage cavity, and the liquid outlet direction of the liquid outlet is toward the first gap.

[0008] The drying mechanism is arranged downstream of the sizing mechanism along the transmission direction of the carbon fiber cloth. The drying mechanism includes two groups of drying components arranged on the frame. The two groups of drying components are arranged at intervals along the gravity direction to form a second gap for the carbon fiber cloth to pass through. The drying components include an electric heating element and a fan. The electric heating element has a plurality of through holes, and each through hole penetrates the electric heating element along the gravity direction. The fan and the electric heating element are arranged at intervals along the gravity direction. The fan is located on the side of the electric heating element away from the second gap, and the air outlet direction of the fan is toward the electric heating element.

[0009] The carbon fiber cloth surface sizing and drying device provided in the present application can realize continuous sizing and continuous drying of the carbon fiber cloth, with uniform sizing and high drying efficiency, flexible and convenient operation, which can effectively improve work efficiency and is practical.

[0010] In some alternative embodiments, the sizing drying device for the carbon fiber fabric surface includes a conveying mechanism, and the conveying mechanism is located upstream of the sizing mechanism along the conveying direction.

[0011] Among them, the conveying mechanism includes at least a pair of conveying roller groups arranged on the frame. Each pair of conveying roller groups includes two conveying rollers rotatably arranged on the frame. The two conveying rollers are arranged at intervals in the direction of gravity to form a third gap for the carbon fiber fabric to pass through. The two conveying rollers are configured to rotate synchronously and in opposite directions, and the tangent direction of each conveying roller in contact with the carbon fiber fabric is parallel to the conveying direction.

[0012] Since the two conveying rollers are configured to rotate synchronously and in opposite directions, and the tangent direction of each conveying roller in contact with the carbon fiber fabric is parallel to the conveying direction, when the carbon fiber fabric passes through the third gap, the rotation of the two conveying rollers can drive the carbon fiber fabric to be smoothly conveyed along the conveying direction. At the same time, the carbon fiber fabric is evenly stressed during the conveying process, and the flattening effect is good, which is beneficial to the subsequent uniform sizing of the carbon fiber fabric.

[0013] In some alternative embodiments, the frame has side plates on both sides in the width direction of the carbon fiber fabric. The sizing drying device for the carbon fiber fabric surface further includes a clamping mechanism corresponding to the side walls one by one. The clamping mechanism is slidably arranged on the corresponding side plate along the conveying direction, and the clamping mechanism includes a clamping space for clamping the carbon fiber fabric.

[0014] With the above settings, the clamping mechanism is used to clamp the carbon fiber fabric output from the third gap at the beginning of operation, and guide it to pass through the first gap and the second gap without contact, so as to clamp and guide the running path of the carbon fiber fabric just conveyed, which is beneficial to the continuous sizing and continuous drying of the carbon fiber fabric.

[0015] In some alternative embodiments, the clamping mechanism includes a base, a fixing member, a clamping member and a first driving mechanism. Among them, the base has an abutting surface facing the carbon fiber fabric; the fixing member is connected to the base and protrudes from the abutting surface; the clamping member is slidably arranged on the abutting surface in the direction of gravity, and the clamping member protrudes from the abutting surface. A clamping space is formed between the clamping member and the fixing member; the first driving mechanism is arranged on the base and is in transmission connection with the clamping member, and the first driving mechanism drives the clamping member to reciprocate in the direction of gravity.

[0016] With the above settings, the automatic operation of the clamping mechanism to clamp the carbon fiber fabric output from the third gap at the beginning of operation can be realized, with high clamping accuracy and improved preparation efficiency of the carbon fiber fabric.

[0017] In some optional embodiments, the sizing and drying device for the surface of the carbon fiber cloth further includes a lead screw structure and a second driving mechanism; the side plate is provided with an installation groove along the transmission direction, and the opening of the installation groove faces the carbon fiber cloth; the lead screw structure includes a lead screw and a lead screw nut that cooperates with the lead screw. The lead screw is axially fixed and circumferentially rotatably arranged in the installation groove. The lead screw extends along the transmission direction, and the base passes through the opening and is connected to the lead screw nut; the second driving mechanism is in transmission connection with the lead screw to drive the lead screw to rotate forward and backward.

[0018] Through the above settings, the second driving mechanism can be used to drive the lead screw to rotate forward and backward to drive the clamping mechanism to reciprocate along the transmission direction, which not only improves work efficiency, but also has high moving stability and is conducive to uniform sizing.

[0019] In some optional embodiments, the sizing and drying device for the surface of the carbon fiber cloth further includes an output mechanism. The output mechanism is arranged downstream of the drying mechanism along the transmission direction. The output mechanism includes a first output roller and a second output roller arranged in sequence along the transmission direction. The first output roller and the second output roller are respectively rotatably arranged on the frame.

[0020] Among them, the horizontal plane where the axis of the first output roller is located is lower than the horizontal plane where the axis of the second output roller is located, so as to form a transmission path for the carbon fiber cloth to bypass from the bottom of the first output roller to the top of the second output roller.

[0021] Through the cooperation of the first output roller and the second output roller, the dried carbon fiber cloth first passes through the bottom of the first conveying roller and then bypasses to the top of the second output roller, which is conducive to making it more firm and stable during winding.

[0022] In some optional embodiments, the sizing and drying device for the surface of the carbon fiber cloth further includes a winding mechanism. The winding mechanism is arranged on the frame; the winding mechanism is arranged downstream of the output mechanism along the transmission direction, and the horizontal plane where the top of the winding mechanism is located is lower than the horizontal plane where the bottom of the second output roller is located.

[0023] By arranging the winding mechanism downstream of the output mechanism along the transmission direction and the horizontal plane where the top of the winding mechanism is located is lower than the horizontal plane where the bottom of the second output roller is located, it is conducive to generating a pulling force in cooperation with the second conveying roller, which is conducive to making it more firm and stable during winding and improving the winding effect.

[0024] In some optional embodiments, the winding mechanism is installed on the frame through a quick-release structure.

[0025] Through the setting of the quick-release structure, the winding mechanism can be quickly disassembled and installed from the frame, improving the preparation efficiency.

[0026] In some optional embodiments, the sizing and drying device for the carbon fiber cloth surface further includes a sizing scraping mechanism, which is arranged between the sizing mechanism and the drying mechanism along the transmission direction. The sizing scraping mechanism includes two groups of sizing scraping rollers arranged on the frame, and the two groups of sizing scraping rollers are arranged at intervals in the direction of gravity to form a fourth gap for the carbon fiber cloth to pass through.

[0027] The sizing on the surface of the carbon fiber cloth is scraped by the sizing scraping rollers, so that the sizing is evenly coated on the surface of the carbon fiber cloth.

[0028] In a second aspect, the present application provides an example of a method for sizing and drying the surface of a carbon fiber cloth, which includes: continuously conveying the carbon fiber cloth into the sizing and drying device for the carbon fiber cloth surface provided in the first aspect of the present application to perform sizing operation and drying operation in sequence.

[0029] Among them, in the sizing operation, the carbon fiber cloth passes through the first gap in a non-contact manner, and the liquid outlets on both sides of the carbon fiber cloth spray sizing on the carbon fiber cloth.

[0030] In the drying operation, the electric heating element is heated and the air outlet direction of the fan faces the electric heating element to generate a heat flow in the second gap. The sized carbon fiber cloth passes through the second gap in a non-contact manner and is dried by the heat flow.

[0031] The method for sizing and drying the surface of the carbon fiber cloth provided by the present application, relying on the above-mentioned sizing and drying device for the carbon fiber cloth surface, can realize continuous sizing and continuous drying of the carbon fiber cloth, improve work efficiency. At the same time, non-contact sizing is beneficial to uniform sizing, and is beneficial to improving the subsequent drying efficiency and effect. The sized carbon fiber cloth passes through the second gap in a non-contact manner to be dried by the heat flow, which can avoid destroying the uniformity of the sizing on the surface of the carbon fiber cloth during transmission, and avoid damaging the coating on the surface of the dried carbon fiber.

Detailed implementation manners

[0039] The following will describe the implementation schemes of the present application in detail in conjunction with the embodiments. However, those skilled in the art will understand that the following embodiments are only used to illustrate the present application and should not be regarded as limiting the scope of the present application. For those conditions not specified in the embodiments, they are carried out according to the conventional conditions or the conditions recommended by the manufacturer. Those reagents or instruments not specified by the manufacturer can be obtained as conventional products through commercial purchase.

[0040] The following specifically describes the sizing and drying device and method for the surface of carbon fiber cloth according to the embodiments of the present application:

[0041] Please refer to Figure 1 , the present application provides a sizing and drying device 1000 for the surface of carbon fiber cloth, which includes a frame 10, a sizing mechanism, and a drying mechanism.

[0042] Among them, the frame 10 is used to support the sizing mechanism, the drying mechanism, etc. The frame 10 includes a bottom plate 11 and two side plates 12. The two side plates 12 are respectively arranged on both sides of the width direction of the bottom plate 11. Among them, the width direction of the bottom plate 11 is parallel to the width direction of the carbon fiber cloth. The bottom plate 11 and the two side plates 12 together form an accommodation space, and the accommodation space extends along the transmission direction.

[0043] Among them, the frame 10 further includes support feet 13 which are fixedly arranged on the side of the bottom plate 11 facing away from the accommodation space, and an anti-slip pad is fixedly connected to the bottom of the support feet 13.

[0044] The sizing mechanism includes two sizing members 21 arranged on the frame 10. The two sizing members 21 are arranged at intervals along the gravity direction to form a first gap 22 for the carbon fiber cloth to pass through. The sizing member 21 has a liquid storage cavity (not shown in the figure) and a plurality of liquid outlets 23 communicating with the liquid storage cavity. The liquid outlet direction of the liquid outlet 23 faces the first gap 22.

[0045] It can be understood that the height of the first gap 22 in the gravity direction should be greater than the thickness of the carbon fiber cloth, which is beneficial to uniform sizing.

[0046] Among them, the sizing is carried out by spraying and sprinkling through the liquid outlet 23, which is beneficial to quickly and uniformly size the carbon fiber cloth, and compared with the soaking method, it will not cause excessive slurry on the surface of the carbon fiber cloth, which is beneficial to the quick drying of the sized carbon fiber cloth and improves the preparation efficiency.

[0047] Specifically, the sizing member 21 extends along the width direction, the inside of the sizing member 21 is hollow to form the above-mentioned liquid storage cavity, both ends of the sizing member 21 are respectively connected to the side plates 12, the liquid inlet end of the sizing member 21 extends out of the side plate 12 and is connected with a fixing block 24, and a slurry inlet 25 for externally connecting a pipeline is arranged on the top of the fixing block 24. The slurry inlet 25 communicates with the liquid storage cavity.

[0048] Among them, a plurality of liquid outlet holes can be arranged on the surface of the sizing member 21 facing the first gap 22, and each liquid outlet hole is provided with a liquid outlet 23, or a plurality of spray heads communicating with the liquid storage cavity are connected to the surface of the sizing member 21 facing the first gap 22, and the spray heads are provided with liquid outlets 23.

[0049] In order to make the liquid outlet uniform, the plurality of liquid outlet holes or the plurality of spray heads are arranged in an array.

[0050] Please refer to Figure 1 and Figure 2 , the drying mechanism is arranged downstream of the sizing mechanism along the transmission direction of the carbon fiber cloth. The drying mechanism includes two groups of drying components 30 arranged on the frame 10. The two groups of drying components 30 are arranged at intervals along the gravity direction to form a second gap 31 for the carbon fiber cloth to pass through. The drying component 30 includes an electric heating element 32 and a fan 34. The electric heating element 32 has a plurality of through holes, and each through hole penetrates the electric heating element 32 along the gravity direction. The fan 34 and the electric heating element 32 are arranged at intervals along the gravity direction. The fan 34 is located on the side of the electric heating element 32 facing away from the second gap 31, and the air outlet direction of the fan 34 faces the electric heating element 32.

[0051] It is understandable that the height of the second gap 31 in the gravity direction should be greater than the thickness of the carbon fiber cloth to avoid destroying the uniformity of the slurry on the surface of the sized carbon fiber cloth during transportation and to avoid damaging the coating on the surface of the dried carbon fiber.

[0052] The electric heating element 32 may be an electric heating mesh having through holes after being woven, or a heating plate having through holes, and the selection may be made according to actual needs.

[0053] Since the electric heating element 32 has a plurality of through holes, each through hole passes through the electric heating element 32 along the direction of gravity. Therefore, after the electric heating element 32 is heated, since the fan 34 is located on the side of the electric heating element 32 away from the second gap 31, and the air outlet direction of the fan 34 is toward the electric heating element 32, the fan 34 blows at this time, causing the air to enter the second gap 31 from the through hole, thereby generating a heat flow in the second gap 31. By setting up the two sets of drying components 30, the upper and lower surfaces of the sizing carbon fiber cloth are dried at the same time, which can effectively improve the drying efficiency.

[0054] In summary, the carbon fiber cloth surface sizing and drying device 1000 provided in this application can realize continuous sizing and continuous drying of carbon fiber cloth through the setting of sizing mechanism and drying mechanism. The sizing is uniform and the drying efficiency is high. The operation is flexible and convenient, which can effectively improve work efficiency and is practical.

[0055] For installation stability, the electric heating element 32 is respectively installed on the side plate 12 at both ends in the width direction.

[0056] See also Figure 2 For operational stability, the drying component 30 further includes a support plate 35 , which is mounted on the side plate 12 at both ends in the width direction. The support plate 35 and the electric heating element 32 are spaced apart along the direction of gravity. The support plate 35 is located on the side of the electric heating element 32 away from the second gap 31 . The support plate 35 is provided with at least one frame area 36 , for example, the support plate 35 is provided with two frame areas 36 , which are spaced apart along the width direction, and each frame area 36 is hollowed out. The fan 34 corresponds to the frame area 36 one by one, and the fan 34 is installed in the corresponding frame area 36 and the air outlet direction is toward the electric heating element 32 .

[0057] In some embodiments, please refer to Figure 1 The carbon fiber cloth surface sizing and drying device 1000 includes a conveying mechanism disposed on a frame 10, and the conveying mechanism is located upstream of the sizing mechanism along the transmission direction. That is, the conveying mechanism is used to convey the carbon fiber cloth to the sizing mechanism.

[0058] Among them, the conveying mechanism includes two conveying rollers 41 rotatably arranged on the frame 10. The two conveying rollers 41 are arranged at intervals in the direction of gravity to form a third gap 42 for the carbon fiber cloth to pass through. The two conveying rollers 41 are configured to rotate synchronously and in opposite directions, and the tangent direction of each conveying roller 41 in contact with the carbon fiber cloth is parallel to the conveying direction.

[0059] It can be understood that in order to convey the carbon fiber cloth, the carbon fiber cloth needs to be in contact with each conveying roller 41. Therefore, the height of the third gap 42 in the direction of gravity should be slightly less than or equal to the thickness of the carbon fiber cloth.

[0060] At this time, in order to enable the carbon fiber cloth to pass through the first gap 22 and the second gap 31 without contact, the height of the third gap 42 in the direction of gravity is less than the height of the first gap 22 in the direction of gravity, and the orthographic projection of the third gap 42 in the conveying direction is located within the first gap 22. The height of the third gap 42 in the direction of gravity is less than the height of the second gap 31 in the direction of gravity, and the orthographic projection of the third gap 42 in the conveying direction is located within the second gap 31.

[0061] It can be understood that for the sake of running stability, both ends of each conveying roller 41 are rotatably installed on the side plates 12 respectively, that is, the conveying roller 41 is located within the accommodating space.

[0062] Since the two conveying rollers 41 are configured to rotate synchronously and in opposite directions, and the tangent direction of each conveying roller 41 in contact with the carbon fiber cloth is parallel to the conveying direction, when the carbon fiber cloth passes through the third gap 42, the rotation of the two conveying rollers 41 can be used to drive the carbon fiber cloth to be stably conveyed along the conveying direction. At the same time, the carbon fiber cloth is evenly stressed at each part during the conveying process, and the flattening effect is good, which is beneficial to uniformly sizing the carbon fiber cloth subsequently.

[0063] Such as Figure 1 As shown, the manner in which the two conveying rollers 41 are configured to rotate synchronously and in opposite directions includes: the sizing and drying device 1000 for the surface of the carbon fiber cloth includes a first motor 43 and two meshing gears 44. The first motor 43 is a servo motor. The two gears 44 are located outside the frame 10. The two gears 44 are respectively connected to the two conveying rollers 41. The first motor 43 is installed on the side plate 12, and the output shaft of the first motor 43 is in transmission connection with any one of the gears 44 to drive the rotation of this gear 44 and simultaneously drive the other gear 44 to rotate synchronously, and each gear 44 drives the corresponding conveying roller 41 to rotate synchronously.

[0064] Among them, a first control button can be provided on the frame 10. The control of the first button controls whether the power supply of the first motor 43 is connected, so as to realize the operation or stop of the first motor 43 through the first control button.

[0065] In some embodiments, please refer to Figure 1and Figure 3 and Figure 4 , the frame 10 has two side plates 12 located on both sides in the width direction of the carbon fiber cloth. The sizing and drying device 1000 for the surface of the carbon fiber cloth further includes a clamping mechanism corresponding to each side wall. The clamping mechanism is slidably arranged on the corresponding side plate 12 along the transmission direction. The clamping mechanism includes a clamping space 55 for clamping the carbon fiber cloth.

[0066] With the above settings, the clamping mechanism is used to clamp the carbon fiber cloth output from the third gap 42 at the beginning of operation, and guide it to pass through the first gap 22 and the second gap 31 in a non-contact manner, so as to clamp and guide the running path of the carbon fiber cloth just conveyed, which is beneficial to realizing continuous sizing and continuous drying of the carbon fiber cloth.

[0067] In some embodiments, please refer to Figure 4 , the clamping mechanism includes: a base 51, a fixing member 53, a clamping member 54 and a first driving mechanism 56.

[0068] The base 51 has an abutting surface facing the carbon fiber cloth; the fixing member 53 is connected to the base 51 and protrudes from the abutting surface; the clamping member 54 is slidably arranged on the abutting surface along the gravity direction, the clamping member 54 protrudes from the abutting surface, and a clamping space 55 is formed between the clamping member 54 and the fixing member 53; the first driving mechanism 56 is arranged on the base 51 and is in transmission connection with the clamping member 54. The first driving mechanism 56 drives the clamping member 54 to reciprocate along the gravity direction. Among them, the first driving mechanism 56 includes an electric telescopic rod or a micro cylinder.

[0069] Optionally, the abutting surface is provided with a guiding portion (not shown in the figure) extending along the gravity direction. The guiding portion is a sliding groove, and the clamping member 54 is provided with a sliding rail (not shown in the figure) cooperating with the guiding portion, or the guiding portion is a sliding rail, and the clamping member 54 is provided with a sliding groove cooperating with the guiding portion. For example, the cross section of the sliding rail is T-shaped. Through the above settings, the clamping member 54 can be slidably arranged on the guiding portion along the gravity direction, and the clamping member 54 is restricted from disengaging from the guiding portion.

[0070] With the above settings, the automatic operation of the clamping mechanism for clamping the carbon fiber cloth output from the third gap at the beginning of operation can be realized, with high clamping accuracy and improved preparation efficiency of the carbon fiber cloth.

[0071] In some embodiments, please continue to refer to Figure 1 , Figure 3 and Figure 4 , the sizing and drying device 1000 for the surface of the carbon fiber cloth further includes a lead screw 61 structure and a second driving mechanism 62.

[0072] The side plate 12 is provided with a mounting groove 14 along the transmission direction, and the opening of the mounting groove 14 faces the carbon fiber cloth; the screw rod 61 structure includes a screw rod 61 and a screw rod nut 63 cooperating with the screw rod 61, the screw rod 61 is axially fixed and circumferentially rotatable and is arranged in the mounting groove 14, the screw rod 61 extends along the transmission direction, and the base 51 passes through the opening and is connected to the screw rod nut 63; the second driving mechanism 62 is transmission-connected to the screw rod 61 to drive the screw rod 61 to rotate forward and reverse.

[0073] Through the above arrangement, the second driving mechanism 62 can drive the screw rod 61 to rotate forward and reverse to drive the clamping mechanism to move back and forth along the transmission direction, which not only improves work efficiency but also ensures high movement stability, which is conducive to uniform sizing.

[0074] Optionally, the carbon fiber cloth surface sizing and drying device 1000 may also include a controller (not shown) and a position sensor (not shown), the position sensor is configured to obtain the position of the clamping mechanism in the transmission direction in real time, the controller is connected to the first drive mechanism 56, the second drive mechanism 62 and the position sensor respectively, and the controller is used to obtain the position of the clamping mechanism in the transmission direction in real time according to the position sensor and control the operating status of the first drive mechanism 56 and the second drive mechanism 62.

[0075] In some embodiments, see Figure 1 as well as Figure 3 The carbon fiber cloth surface sizing and drying device 1000 further includes an output mechanism, which is arranged downstream of the drying mechanism along the transmission direction and is used to output the dried carbon fiber cloth.

[0076] The output mechanism includes a first output roller 71 and a second output roller 72 arranged in sequence along the transmission direction. The first output roller 71 and the second output roller 72 are respectively rotatably provided on the frame 10; wherein the horizontal plane where the axis of the first output roller 71 is located is lower than the horizontal plane where the axis of the second output roller 72 is located, so as to form a transmission path for the carbon fiber cloth to bypass from the bottom of the first output roller 71 to the top of the second output roller 72.

[0077] Through the cooperation of the first output roller 71 and the second output roller 72, the dried carbon fiber cloth first passes through the bottom of the first conveyor roller 41 and then goes around to the top of the second output roller 72, which is conducive to making it tighter and more stable when winding.

[0078] In order to output the carbon fiber cloth more smoothly, two conveying rollers 41 serve as the first conveying roller 41 and the second conveying roller 41. The second conveying roller 41 is located below the first conveying roller 41. At this time, the horizontal plane where the top of the second conveying roller 41 is located (the tangent line of the highest point is parallel to the conveying direction) coincides with the horizontal plane where the bottom of the first output roller 71 is located, so that the carbon fiber cloth should be horizontal during transmission, or the vertical deviation does not exceed 5 cm, so that the carbon fiber cloth should be in a basically horizontal state during transmission.

[0079] In some embodiments, refer to Figure 1 、 Figure 3 and Figure 5 , the sizing and drying device 1000 for the surface of the carbon fiber cloth further includes a winding mechanism, and the winding mechanism is arranged on the frame 10; the winding mechanism is arranged downstream of the output mechanism along the transmission direction, and the horizontal plane where the top of the winding mechanism is located is lower than the horizontal plane where the bottom of the second output roller 72 is located.

[0080] By arranging the winding mechanism downstream of the output mechanism along the transmission direction, and the horizontal plane where the top of the winding mechanism is located is lower than the horizontal plane where the bottom of the second output roller 72 is located, it is beneficial to cooperate with the second conveying roller 41 to generate tension, which is beneficial to more firm and stable winding during winding and improves the winding effect.

[0081] Exemplarily, the winding mechanism is a winding roller 81, and the winding roller 81 extends along the width direction. Both ends of each winding roller 81 are rotatably installed on the side plates 12.

[0082] Among them, the winding roller 81 is detachably installed on the frame 10 for easy replacement of the winding roller 81.

[0083] Exemplarily, the side plate 12 is installed with a rotating shaft 82 that is rotatable in different circumferences axially, and the winding roller 81 is detachably connected to the rotating shaft 82. The sizing and drying device 1000 for the surface of the carbon fiber cloth may further include a second motor 83, and the driving end of the second motor 83 is in transmission connection with the rotating shaft 82 to drive its rotation.

[0084] Optionally, a second control button (not shown in the figure) may be provided on the frame 10 to control whether the power supply of the second motor 83 is connected, so as to realize the operation or stop of the second motor 83 through the second control button. It should be noted that the first control button and the second control button may be the same one, or two independently set buttons, and the first control button and the second control button may be used independently or set in linkage.

[0085] In some embodiments, the winding mechanism is installed on the frame 10 through a quick-release structure.

[0086] By setting up a quick-release structure, the winding mechanism can be quickly disassembled from and installed on the frame 10, improving the preparation efficiency.

[0087] As Figure 5 shown, the quick-release structure includes a first connecting member 91, a second connecting member 93, and a pin 95. One end of the first connecting member 91 is connected to the end of the winding roller 81, and the other end is provided with a convex block 94. One end of the second connecting member 93 is connected to the rotating shaft 82, and the other end is provided with two limiting plates 92 arranged at intervals. A clamping groove for cooperating with the convex block 94 is formed between the two limiting plates 92. Each limiting plate 92 is provided with a first through hole, and the convex block 94 is provided with a second through hole. The pin 95 is detachably inserted through the first through hole and the second through hole, and the quick release of the winding mechanism is realized through the above settings.

[0088] In some embodiments, the sizing and drying device 1000 for the carbon fiber cloth surface further includes a sizing scraping mechanism (not shown in the figure). The sizing scraping mechanism is arranged between the sizing mechanism and the drying mechanism along the transmission direction. The sizing scraping mechanism includes two groups of sizing scraping rollers arranged on the frame 10. The two groups of sizing scraping rollers are arranged at intervals along the gravity direction to form a fourth gap for the carbon fiber cloth to pass through.

[0089] The sizing on the surface of the carbon fiber cloth is scraped by the sizing scraping rollers, so that the sizing is evenly coated on the surface of the carbon fiber cloth.

[0090] It can be understood that, in order to scrape the sizing evenly, the width of the fourth gap should be the same as or slightly larger than the thickness of the carbon fiber cloth after uniform sizing, and can be specifically adjusted according to actual needs, and will not be limited here.

[0091] The present application also provides a method for sizing and drying the carbon fiber cloth surface, which includes: continuously conveying the carbon fiber cloth into the above-mentioned sizing and drying device 1000 for the carbon fiber cloth surface to perform sizing operation and drying operation in sequence.

[0092] Among them, in the sizing operation, the carbon fiber cloth passes through the first gap 22 in a non-contact manner, and the liquid outlets 23 on both sides of the carbon fiber cloth spray sizing on the carbon fiber cloth.

[0093] In the drying operation, the electric heating element 32 is heated and the air outlet direction of the fan faces the electric heating element 32 to generate a heat flow in the second gap 31. The sized carbon fiber cloth passes through the second gap 31 in a non-contact manner and is dried by the heat flow.

[0094] The sizing and drying method for the surface of carbon fiber cloth provided by this application, relying on the above-mentioned sizing and drying device 1000 for the surface of carbon fiber cloth, can achieve continuous sizing and continuous drying of carbon fiber cloth, improve work efficiency. At the same time, non-contact sizing is beneficial to uniform sizing and is conducive to improving the subsequent drying efficiency and effect. The carbon fiber cloth after sizing passes through the second gap 31 non-contact to be dried by heat flow, which can avoid damaging the uniformity of the surface sizing of the carbon fiber cloth during transmission and avoid damaging the coating on the surface of the dried carbon fiber.

[0095] Optionally, the step of continuously conveying the carbon fiber cloth to the above-mentioned sizing and drying device 1000 for the surface of carbon fiber cloth includes: starting the first motor 43 to drive the two conveying rollers 41 to rotate synchronously and in opposite directions, thereby driving the carbon fiber cloth located between the two conveying rollers 41 and in contact with the conveying roller to move in the conveying direction, and sequentially passing through the first gap 22, the fifth gap, and the second gap 31 without contact and moving to the output mechanism, and being wound by the winding mechanism.

[0096] It should be noted that during the first transmission of the carbon fiber cloth, the second driving mechanism 62 can be used to drive the lead screw 61 to rotate, so as to drive the clamping mechanism to move to a position close to the conveying roller 41. Among them, the clamping member 54 and the fixing member 53 are located on both sides of the carbon fiber cloth in the thickness direction. The first drive is used to drive the clamping member 54 to move towards the side close to the fixing member 53 along the gravity direction to clamp the carbon fiber cloth, and then the second driving mechanism 62 is used to drive the lead screw 61 to rotate in the reverse direction, so as to drive the carbon fiber cloth to be sized and dried in sequence and then output from the output mechanism, guiding the running path of the carbon fiber cloth during the initial operation.

[0097] It can be understood that in order to ensure the heating effect, when the sizing and drying device 1000 for the surface of carbon fiber cloth runs for the first time, the electric heating element 32 and the fan 34 should be started in advance for preheating.

[0098] In summary, the sizing and drying device and method for the surface of carbon fiber cloth provided by this application can achieve continuous sizing and continuous drying of carbon fiber cloth, with uniform sizing and high drying efficiency, flexible and convenient operation, can effectively improve work efficiency, reduce production costs, and has practicality.

[0099] The above are only specific embodiments of this application and are not used to limit this application. For those skilled in the art, this application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included within the protection scope of this application.
