Description

Technical Field

[0001] This utility model belongs to the field of carbon fiber prepreg production technology, specifically relating to a flattening device for carbon fiber prepreg production. Background Technology

[0002] Carbon fiber prepreg, as a key intermediate material in the manufacture of high-performance composite materials, is increasingly widely used in aerospace, sporting goods, and high-end industrial fields. During production, wide-width prepregs often need to be cut into smaller sheets of specific sizes to meet the requirements of subsequent lay-up and molding processes.

[0003] In the production of carbon fiber prepreg, flattening equipment is a crucial device for ensuring the carbon fiber material is flat and wrinkle-free. Traditional flattening equipment typically relies on manual operation, and the process of threading carbon fiber is cumbersome, requiring operators to repeatedly pass the carbon fiber up and down through multiple rollers. This is not only time-consuming and labor-intensive but also prone to damaging the carbon fiber due to improper operation. Therefore, there is an urgent need for a flattening device for carbon fiber prepreg production.

[0004] A patent with publication number CN220316807U discloses a flattening device for producing carbon fiber prepreg. The device includes a first roller, a second roller, a first servo motor, a second servo motor, a T-block, a T-slot, a sprocket, a chain, a second gear, and a third gear. In operation, the third gear is first pulled, causing the T-block to slide within the T-slot, thus disengaging the third gear from the second gear. Then, the first servo motor is activated, and with the help of the sprocket and chain, the second roller moves upward, intersecting with the first roller. Next, one end of the carbon fiber is passed between the first and second rollers. Afterward, the second servo motor controls the second roller to move downward until it is level with the first roller, pushing the third gear. With the help of the T-block and T-slot, the third gear re-engages with the second gear, thus achieving the winding of the carbon fiber.

[0005] However, before the above scheme controls the second roller to move upward using the first servo motor, it is necessary to pull the third gear to disengage the second and third gears, so as to avoid the engagement of the two gears affecting the upward movement of the second roller. Similarly, after the first servo motor controls the second roller to move downward, it is necessary to push the third gear to re-engage the second and third gears. The entire scheme is cumbersome to operate, not convenient to use, and has a low degree of automation, which increases the labor intensity of the staff and is not conducive to practical promotion and use. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model provides a flattening device for the production of carbon fiber prepreg.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A flattening device for producing carbon fiber prepreg includes a mounting frame. A first U-shaped plate and a second U-shaped plate are slidably mounted on the outer surface of the mounting frame in a vertical direction. The first and second U-shaped plates are symmetrically positioned on both sides of the mounting frame. A driving mechanism is provided on the mounting frame to drive the first and second U-shaped plates to slide synchronously. Several sliders are slidably mounted on the inside of the mounting frame in a vertical direction, with pairs of sliders symmetrically positioned on both sides of the mounting frame. Several first rollers are rotatably mounted inside the mounting frame, and a second roller is rotatably mounted between each pair of symmetrical sliders. The first and second rollers are spaced apart. A first gear is fixedly fitted onto one end of a first rotating shaft inside each first roller. A splined shaft is fixedly mounted onto one end of a second rotating shaft inside each second roller, and a splined sleeve that mates with the splined shaft is slidably fitted onto the other end. A second gear is fixedly fitted onto the outer surface of each splined sleeve, and the second gear engages with the first gear in a contact-type transmission. A transmission component is provided between the first U-shaped plate and the splined sleeves, and the first U-shaped plate also engages with the splined sleeves in a contact-type transmission.

[0009] Furthermore, the driving mechanism includes a first motor, two fixing plates fixedly mounted on the outer surface of the mounting frame, and a threaded rod rotatably mounted in each fixing plate along the vertical direction. The first U-shaped plate and the second U-shaped plate are respectively threadedly engaged with the corresponding threaded rod, and a second bevel gear is fixedly sleeved at the bottom of each threaded rod. The mounting frame not only has the first motor fixedly mounted on it, but also has a connecting shaft rotatably mounted on it. The output shaft of the first motor is coaxially and fixedly connected to one end of the connecting shaft. Two first bevel gears are fixedly sleeved on the outer surface of the connecting shaft, and the first bevel gears and the second bevel gears mesh and transmit power in a one-to-one correspondence.

[0010] Furthermore, the mounting bracket has a groove for the slider to slide.

[0011] Furthermore, two mating grooves are provided on the second U-shaped plate, and the end of each second rotating shaft without a spline shaft is limited and slidably disposed in the mating groove.

[0012] Furthermore, a limiting plate is fixedly installed on the outer surface of the mounting bracket, and the spline sleeve slides in conjunction with the limiting plate.

[0013] Furthermore, the transmission component includes a connecting rod, a connecting plate rotatably sleeved on the outer surface of the spline sleeve, one end of the connecting rod being hinged to the connecting plate, and the other end being hinged to the first U-shaped plate.

[0014] Furthermore, a second motor is fixedly mounted on the mounting bracket, and the output shaft of the second motor is coaxially and fixedly connected to one end of one of the first rotating shafts.

[0015] Furthermore, an electric telescopic rod is fixedly installed on the mounting frame, and an adhesive plate is fixedly installed on the telescopic shaft of the electric telescopic rod. The adhesive plate is located below the first roller and the second roller.

[0016] This application has the following beneficial effects:

[0017] During the synchronous upward movement of the first and second U-shaped plates driven by the drive mechanism, the spline sleeve automatically slides on the surface of the spline shaft with the assistance of the transmission components, disengaging the second gear from the first gear. Then, the first and second U-shaped plates drive the second roller upward to allow the carbon fiber to pass through. Similarly, during the descent of the first and second U-shaped plates, the second roller descends first and becomes level with the first roller, after which the second gear automatically engages with the first gear. This application achieves a continuous action from gear disengagement to roller lifting through the cooperation of the drive mechanism and transmission components. The operation is simple, freeing operators from repetitive and technically demanding manual labor, greatly reducing labor intensity, and facilitating practical application.

[0027] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: a flattening device for producing carbon fiber prepreg includes an H-shaped mounting frame 1. The outer surface of the mounting frame 1 is vertically limited and slidably arranged with a first U-shaped plate 8 and a second U-shaped plate 17. The first U-shaped plate 8 and the second U-shaped plate 17 are symmetrically arranged on both sides of the mounting frame 1.

[0028] The drive mechanism includes a first motor 2, two fixing plates 6 are fixedly installed on the outer surface of the mounting frame 1, and a threaded rod 7 is rotatably installed in each fixing plate 6 in the vertical direction. The first U-shaped plate 8 and the second U-shaped plate 17 are respectively threadedly engaged with the corresponding threaded rod 7, and a second bevel gear 5 is fixedly sleeved at the bottom of each threaded rod 7.

[0029] The mounting bracket 1 is used to fix the first motor 2 and to rotatably connect the connecting shaft 3. The output shaft of the first motor 2 is coaxially and fixedly connected to one end of the connecting shaft 3. Two first bevel gears 4 are fixedly sleeved on the outer surface of the connecting shaft 3. The first bevel gears 4 and the second bevel gears 5 mesh and transmit power in a one-to-one correspondence.

[0030] Furthermore, two mating grooves 19 are provided on the second U-shaped plate 17.

[0031] In addition, several sliders 15 are slidably arranged in the vertical direction inside the mounting frame 1, and the sliders 15 are symmetrically arranged in pairs on both sides of the mounting frame 1.

[0032] Furthermore, a groove 26 is provided on the mounting bracket 1 for the slider 15 to slide.

[0033] A plurality of first rotating shafts 9 are rotatably arranged inside the mounting frame 1, and a first roller 16 is fixedly sleeved on the outer surface of each first rotating shaft 9; a second rotating shaft 14 is rotatably arranged between two symmetrical sliders 15, and a second roller 21 is fixedly sleeved on the outer surface of each second rotating shaft 14. The first rollers 16 and the second rollers 21 are arranged at intervals. (Specifically, in this application, there are preferably three first rollers 16 and two second rollers 21, with the two second rollers 21 arranged between the three first rollers 16.)

[0034] In addition, one end of each second rotating shaft 14 is fixedly provided with a spline shaft 13 and slidably fitted with a spline sleeve 12 that mates with the spline shaft 13. The outer surface of each spline sleeve 12 is fixedly fitted with a second gear 22. One end of each first rotating shaft 9 is fixedly fitted with a first gear 20, and the first gear 20 and the adjacent second gear 22 engage in contact-type transmission.

[0035] Furthermore, the end of each second rotating shaft 14 without a splined shaft 13 is limited and slidably disposed within the mating groove 19.

[0036] Furthermore, a limiting plate 25 is fixedly installed on the outer surface of the mounting bracket 1, and the spline sleeve 12 slides in conjunction with the limiting plate 25.

[0037] In addition, the first U-shaped plate 8 is provided with a transmission component between several spline sleeves 12, and also has a contact transmission engagement with several spline sleeves 12.

[0038] The transmission component includes a connecting rod 10, a connecting plate 11 rotatably mounted on the outer surface of a spline sleeve 12, one end of the connecting rod 10 is hinged to the connecting plate 11, and the other end is hinged to the first U-shaped plate 8.

[0039] Furthermore, a second motor 18 is fixedly mounted on the mounting bracket 1, and one end of the second motor 18 is coaxially and fixedly connected to one end of one of the first rotating shafts 9.

[0040] Furthermore, an electric telescopic rod 23 is fixedly installed on the mounting frame 1, and an adhesive plate 24 is fixedly installed on the telescopic shaft of the electric telescopic rod 23. The adhesive plate 24 is located below the first roller 16 and the second roller 21.

[0041] Working principle: When carbon fiber needs to be threaded, the first motor 2 is started. The output shaft of the first motor 2 drives the connecting shaft 3 and the two first bevel gears 4 on it to rotate together. The first bevel gear 4 transmits power to the second bevel gear 5 that meshes with it, thereby driving the two threaded rods 7 to rotate synchronously. Since the first U-shaped plate 8 and the second U-shaped plate 17 are threadedly engaged with the threaded rods 7 and are vertically limited on the mounting bracket 1, the rotation of the threaded rods 7 will drive the first U-shaped plate 8 and the second U-shaped plate 17 to move upward synchronously.

[0042] In the initial stage of the first U-shaped plate 8 rising, due to the limitation of the second roller 21's own weight, the first U-shaped plate 8 will push the connecting plate 11 and the spline sleeve 12 to slide outward via the connecting rod 10 until the top of the first U-shaped plate 8 contacts the spline sleeve 12. When the top of the first U-shaped plate 8 contacts the spline sleeve 12, the second gear 22 just disengages from the first gear 20.

[0043] Meanwhile, during the above process, the mating groove 19 on the second U-shaped plate 17 will slide relative to the second rotating shaft 14. When the top of the first U-shaped plate 8 contacts the spline sleeve 12, the second rotating shaft 14 will also just contact the bottom of the mating groove 19.

[0044] After the top of the first U-shaped plate 8 contacts the spline sleeve 12 and the second gear 22 disengages from the first gear 20, as the first U-shaped plate 8 and the second U-shaped plate 17 continue to rise, the first U-shaped plate 8 pushes the second rotating shaft 14 upward through the spline sleeve 12 and the spline shaft 13, and the second U-shaped plate 17 pushes the second rotating shaft 14 upward through the mating groove 19, so that the second rotating shaft 14 drives the slider 15 to slide upward along the slide groove 26, and finally lifts the second roller 21 above the first roller 16, forming a horizontal channel.

[0045] At this point, the first motor 2 is turned off. The operator can then easily pass the carbon fiber through the horizontal channel formed between the first roller 16 and the second roller 21, a process that is extremely simple.

[0046] After the carbon fiber is threaded, the output shaft of the first motor 2 is controlled to rotate in the opposite direction, so that the first U-shaped plate 8 and the second U-shaped plate 17 descend synchronously, and the second rotating shaft 14 and the second roller 21 descend first under the action of gravity.

[0047] When the second roller 21 descends to the same horizontal position as the first roller 16, the slider 15 is located at the bottom of the chute 26. As the first U-shaped plate 8 and the second U-shaped plate 17 continue to descend, the first U-shaped plate 8 pulls the connecting plate 11 and the spline sleeve 12 inward through the connecting rod 10, so that the second gear 22 re-engages with the first gear 20.

[0048] Subsequently, the second motor 18 is started, and the output shaft of the second motor 18 drives a first rotating shaft 9 and a first gear 20 thereon to rotate. Through the meshing of the first gear 20 and the second gear 22, the power is transmitted to all the second rotating shafts 14, so that the first roller 16 and the second roller 21 rotate synchronously in opposite directions, thereby performing an efficient flattening operation on the carbon fiber passing through them.

[0049] During this process, the electric telescopic rod 23 is activated, which lifts the adhesive plate 24 upwards along its telescopic axis, allowing the surface of the adhesive plate 24 to contact the surfaces of the first roller 16 and the second roller 21, automatically removing the carbon fiber debris adhering to its surface, keeping the equipment clean, and preventing debris from contaminating the product and working environment.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
