Description
Technical Field
[0001] This application relates to the technical field of unwinding equipment, and in particular to a carbon fiber strip unwinding device and unwinding process. Background Technology
[0002] Carbon fiber tape, as a composite material with excellent properties, is widely used in aerospace, automotive manufacturing, sporting goods, and construction. Due to its high strength, lightweight, and corrosion resistance, carbon fiber has become an ideal alternative to traditional materials in many applications. With the continuous development of the carbon fiber industry, the market demand for carbon fiber tape is increasing daily.
[0003] The purchased carbon fiber strips are usually wound on a roll, and they need to be unwound during the subsequent weaving process. However, multiple carbon fiber strips are needed for one weaving. If each carbon fiber strip needs to be unwound, a lot of space is required to place the unwound equipment, resulting in a large footprint. Summary of the Invention
[0004] To address the issue of large space requirements for carbon fiber strip unwinding equipment, this application provides a carbon fiber strip unwinding device and unwinding process.
[0005] The technical solution adopted in this application for a carbon fiber strip unwinding device and unwinding process is as follows: A carbon fiber strip unwinding device includes a support frame and several storage boxes. Several rotating rollers are rotatably mounted on the side of the support frame. Clamping components for clamping carbon fiber strip rolls are provided on the rotating rollers. A motor is mounted on the support frame, and the output end of the motor is coaxially and fixedly connected to the end of the rotating rollers. Several connecting plates are fixed on the side of the support frame. Connecting sleeves are fixedly inserted through the connecting plates. Air blowing holes are opened on the inner circumferential surface of the connecting sleeves and are inclined downwards. An air supply component for supplying air into the air blowing holes is provided on the connecting sleeves.
[0006] By adopting the above technical solution, the carbon fiber strip roll is placed on the rotating roller, the end of the carbon fiber strip is passed through the connecting sleeve and extended into the storage box, and then the motor is started. The motor drives the rotating roller to rotate, and the rotating roller drives the carbon fiber strip roll to rotate, thereby unwinding the carbon fiber strip. The air blowing hole blows air downwards into the carbon fiber strip in the connecting sleeve, thereby pushing the carbon fiber strip downwards, thus realizing the unwinding of the carbon fiber strip. It occupies less space, has high unwinding efficiency, and is less likely to damage the carbon fiber strip.
[0007] Preferably, the connecting sleeve includes a fixed sleeve and a limiting sleeve. The bottom end of the limiting sleeve is coaxially and fixedly connected to the top end of the fixed sleeve. The inner diameter of the limiting sleeve is smaller than the inner diameter of the fixed sleeve. The air supply assembly includes an air blowing pipe. The top of the fixed sleeve is provided with an mounting ring cavity. The top of the air blowing hole is connected to the mounting ring cavity. The bottom end of the air blowing hole is inclined towards the central axis close to the fixed sleeve. The air blowing pipe is connected to the mounting ring cavity. An air compressor for supplying air to the air blowing pipe is installed on the support frame.
[0008] By adopting the above technical solution, the carbon fiber strip is passed through the limiting sleeve and the fixing sleeve from top to bottom. When the carbon fiber strip enters the fixing sleeve, it is located in the middle position of the fixing sleeve. The air compressor is started so that the gas enters the air blowing pipe, then enters the mounting ring cavity, and then blows downward through the air blowing hole to provide downward aerodynamic force to the carbon fiber strip.
[0009] Preferably, the clamping member includes a fixed disk and a movable disk. The fixed disk is sleeved and fixed to the outer periphery of the rotating roller. A movable sleeve is fixed to the side of the movable disk. A fastening screw is fixed to the end of the rotating roller away from the motor. The movable sleeve is threadedly connected to the fastening screw.
[0010] By adopting the above technical solution, the carbon fiber strip roll is first placed around the outer circumference of the rotating roller, and then the movable disc is placed around the outer circumference of the rotating roller. At the same time, the movable sleeve is rotated so that the movable disc and the fixed disc clamp the carbon fiber strip roll, so that the rotating roller can drive the carbon fiber strip roll to rotate synchronously.
[0011] Preferably, the fixed disk and the movable disk are respectively fixed with limiting cylinders on their respective inner sides, and the two limiting cylinders are provided with sharp points on their respective inner sides.
[0012] By adopting the above technical solution, after the carbon fiber strip roll is sleeved on the outer periphery of the rotating roller, the carbon fiber strip roll abuts against the tip of the limiting cylinder, so that the carbon fiber strip roll and the rotating roller can be coaxially arranged, so that the rotating roller can drive the carbon fiber strip roll to rotate smoothly.
[0013] Preferably, two rotating rods are rotatably mounted on the bottom surface of the connecting plate, and two connecting rods are fixedly sleeved on the outer circumferential surface of the rotating rods. An abutting roller is rotatably mounted between the two connecting rods, and the outer circumferential surfaces of the two abutting rollers can abut against each other. The connecting plate is provided with a driving component for driving the two connecting rods to rotate.
[0014] By adopting the above technical solution, after the carbon fiber strip is unwound from the roll, the two rotating rods are rotated. The rotating rods drive the two abutting rollers to rotate in a direction that moves closer to each other through the connecting rods. This causes the two abutting rollers to clamp the tail end of the carbon fiber strip, so as to prevent the tail end of the carbon fiber strip from falling into the storage box and being difficult to find.
[0015] Preferably, a clip is installed on the top of the storage box.
[0016] By adopting the above technical solution, after the carbon fiber strip is unwound, two abutment rollers clamp the tail of the carbon fiber strip. The worker only needs to pull the tail of the carbon fiber strip downward to separate the tail of the carbon fiber strip from the abutment rollers. Then, the clips on the storage box are used to clamp the tail of the carbon fiber strip so that the end of the carbon fiber strip can be quickly found during subsequent weaving.
[0017] Preferably, the driving component includes a cylinder mounted on the connecting plate, a moving block fixed to the piston rod end of the cylinder, a horizontally arranged upper rack fixed to the top of the moving block, a horizontally arranged lower rack fixed to the bottom of the moving block, and a gear fixedly sleeved on the outer periphery of the rotating rod, one of the gears meshing with the upper rack and the other gear meshing with the lower rack.
[0018] By adopting the above technical solution, the cylinder is started, and the cylinder drives the upper rack and lower rack to move synchronously through the moving block. The upper rack and lower rack drive the two gears to rotate in opposite directions, which in turn drives the two rotating rods to rotate in opposite directions, so that the two abutting rollers can abut against each other.
[0019] Preferably, the support frame is equipped with a plurality of detection plates, which are located directly below the rotating roller. An edge sensor is installed on the detection plate. The edge sensor is used to detect whether the carbon fiber strip has been unwound. The edge sensor can output a signal indicating that there is no carbon fiber strip. The cylinder responds to the signal indicating that there is no carbon fiber strip to control the opening and closing.
[0020] By adopting the above technical solution, when the edge sensor outputs a signal that there is no carbon fiber strip, the cylinder is activated, thereby causing the two abutment rollers to clamp the tail of the carbon fiber strip.
[0021] A carbon fiber strip unwinding process includes the following steps: S1. Place the carbon fiber strip roll on the rotating roller, use the clamping device to fix the carbon fiber strip to the rotating roller, and then pass the end of the carbon fiber strip through the connecting sleeve and into the storage box. S2. Start the motor. The motor drives the rotating roller and the carbon fiber strip drum to rotate synchronously. The air blowing hole blows air downwards onto the carbon fiber strip in the connecting sleeve. The carbon fiber strip moves downwards and falls into the storage box.
[0022] In summary, this application includes at least one of the following beneficial technical effects: The carbon fiber strip roll is placed on the rotating roller, and the end of the carbon fiber strip is passed through the connecting sleeve and inserted into the storage box. Then the motor is started, and the motor drives the rotating roller to rotate, which in turn drives the carbon fiber strip roll to rotate, thus unwinding the carbon fiber strip. The air blowing hole blows air downwards into the carbon fiber strip in the connecting sleeve, thereby pushing the carbon fiber strip downwards, thus realizing the unwinding of the carbon fiber strip. It occupies less space, has high unwinding efficiency, and is less likely to damage the carbon fiber strip. The carbon fiber strip is passed through the limiting sleeve and the fixing sleeve from top to bottom. When the carbon fiber strip enters the fixing sleeve, it is located in the middle of the fixing sleeve. The air compressor is started so that the gas enters the air blowing pipe, then enters the mounting ring cavity, and then blows downward through the air blowing hole to provide downward aerodynamic force to the carbon fiber strip. After the carbon fiber strip is unwound from the spool, rotate the two rotating rods. The rotating rods drive the two abutment rollers to rotate in a direction that brings them closer to each other, so that the two abutment rollers clamp the tail end of the carbon fiber strip to prevent the tail end of the carbon fiber strip from falling into the storage box and being difficult to find.

Detailed Implementation
[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0029] This application discloses a carbon fiber strip unwinding device and unwinding process. (Refer to...) Figure 1 and Figure 2 The carbon fiber strip unwinding device includes a support frame 1 and several storage boxes 2. Clamps 21 for holding the carbon fiber strip are installed on the top of each storage box 2. Several rotating rollers 11 are rotatably mounted on the side of the support frame 1, and clamping elements 3 for clamping the carbon fiber strip roll are provided on the rotating rollers 11. A motor 12 is mounted on the support frame 1, and the output end of the motor 12 is coaxially and fixedly connected to the end of the rotating rollers 11.
[0030] Reference Figure 1 and Figure 2 The clamping component 3 includes a fixed disk 31 and a movable disk 32. Limiting cylinders 33 are fixed to the inner sides of the fixed disk 31 and the movable disk 32, respectively, and each limiting cylinder 33 has a pointed tip on its inner side. The fixed disk 31 is sleeved and fixed to the outer periphery of the rotating roller 11, and a movable sleeve 321 is fixed to the side of the movable disk 32. A fastening screw 111 is fixed to the end of the rotating roller 11 away from the motor 12, and the movable sleeve 321 is threadedly connected to the fastening screw 111.
[0031] First, the carbon fiber strip roll is placed around the outer circumference of the rotating roller 11. Then, the movable disc 32 is placed around the outer circumference of the rotating roller 11. At the same time, the movable sleeve 321 is rotated, and the tip of the carbon fiber strip roll abuts against the tip of the limiting cylinder 33, so that the carbon fiber strip roll and the rotating roller 11 can be coaxially arranged, so that the rotating roller 11 can drive the carbon fiber strip roll to rotate smoothly.
[0032] Reference Figure 1 and Figure 3 A plurality of connecting plates 13 are fixed to the side of the support frame 1, and connecting sleeves 4 are fixedly inserted through the connecting plates 13. The connecting sleeves 4 include a fixed sleeve 41 and a limiting sleeve 42. The bottom end of the limiting sleeve 42 is coaxially and fixedly connected to the top end of the fixed sleeve 41, and the inner diameter of the limiting sleeve 42 is smaller than the inner diameter of the fixed sleeve 41. The top of the fixed sleeve 41 is provided with a mounting annular cavity 411, and the inner top surface of the fixed sleeve 41 is provided with an air blowing hole 412 communicating with the mounting annular cavity 411. The bottom end of the air blowing hole 412 is inclined toward the central axis close to the fixed sleeve 41. An air blowing pipe 43 communicating with the mounting annular cavity 411 is fixed to the top of the fixed sleeve 41, and an air compressor 44 for supplying air to the air blowing pipe 43 is installed on the support frame 1.
[0033] The carbon fiber strip is passed through the limiting sleeve 42 and the fixing sleeve 41 from top to bottom. When the carbon fiber strip enters the fixing sleeve 41, it is located in the middle position of the fixing sleeve 41. The air compressor 44 is started, so that the gas enters the air blowing pipe 43, then enters the mounting ring cavity 411, and then blows downward through the air blowing hole 412, providing downward aerodynamic force to the carbon fiber strip.
[0034] Reference Figure 3 and Figure 4 Two rotating rods 5 are rotatably mounted on the bottom surface of the connecting plate 13, and two connecting rods 51 are fixedly fitted onto the outer circumference of the rotating rods 5. An abutting roller 52 is rotatably mounted between the two connecting rods 51, and the outer circumferences of the two abutting rollers 52 can abut against each other. A cylinder 53 is fixed to the side of the connecting plate 13, and a moving block 54 is fixed to the end of the piston rod of the cylinder 53. A horizontally arranged upper rack 55 is fixed to the top of the moving block 54, and a horizontally arranged lower rack 56 is fixed to the bottom of the moving block 54. A gear 57 is fixedly fitted onto the outer circumference of the rotating rods 5, with the upper rack 55 located above the gear 57 and the lower rack 56 located below the gear 57. One gear 57 meshes with the upper rack 55, and the other gear 57 meshes with the lower rack 56. Several detection plates 14 are mounted on the support frame 1, and the detection plates 14 are located directly below the rotating roller 11. An edge sensor 141 is installed on the detection plate 14. The edge sensor 141 is used to detect whether the carbon fiber strip has been unwound. The edge sensor 141 can output a signal indicating that there is no carbon fiber strip, and the cylinder 53 responds to the signal to control its opening and closing.
[0035] After the carbon fiber strip is unwound from the spool, the edge sensor 141 outputs a signal indicating no carbon fiber strip, and the cylinder 53 is activated. The cylinder 53 drives the upper rack 55 and the lower rack 56 to move synchronously via the moving block 54. The upper rack 55 and the lower rack 56 drive the two gears 57 to rotate in opposite directions, which in turn drives the two rotating rods 5 to rotate in opposite directions. The two abutting rollers 52 rotate toward each other, so that the two abutting rollers 52 clamp the tail end of the carbon fiber strip to prevent the tail end of the carbon fiber strip from falling into the storage box and being difficult to find.
[0036] A carbon fiber strip unwinding process includes the following steps: S1. Place the carbon fiber strip roll on the rotating roller 11, use the clamping piece 3 to fix the carbon fiber strip to the rotating roller 11, and then pass the end of the carbon fiber strip through the connecting sleeve 4 and extend it into the storage box 2. S2. Start motor 12. Motor 12 drives rotating roller 11 and carbon fiber strip drum to rotate synchronously. Air blowing hole 412 blows air downwards onto carbon fiber strip in connecting sleeve 4. Carbon fiber strip moves downwards and falls into storage box 2.
[0037] The implementation principle of the carbon fiber strip unwinding device in this application embodiment is as follows: the carbon fiber strip roll is placed on the rotating roller 11, the end of the carbon fiber strip is passed through the connecting sleeve 4 and extended into the storage box 2, and then the motor 12 is started to drive the rotating roller 11 to rotate. The rotating roller 11 drives the carbon fiber strip roll to rotate, thereby unwinding the carbon fiber strip. The air blowing hole 412 blows air downwards into the carbon fiber strip in the connecting sleeve 4, thereby pushing the carbon fiber strip to move downwards, thus realizing the unwinding of the carbon fiber strip. It occupies less space, has high unwinding efficiency, and is not easy to damage the carbon fiber strip.
[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
