Description

Technical Field

[0001] The utility model relates to a carbon fiber prepreg cutting mechanism. Background Art

[0002] Carbon fiber prepreg is made by compounding epoxy resin on carbon fiber through high pressure and high temperature technology. The composite material made of carbon fiber yarn, epoxy resin, release paper and other materials through coating, hot pressing, cooling, laminating, winding and other processes is called carbon fiber prepreg, also known as carbon fiber prepreg. It is called prepreg because it is only the initial impregnation of resin and carbon fiber, and the final impregnation is when the product is formed. To summarize the production process of carbon fiber prepreg, a cutting mechanism is usually used to cut the carbon fiber prepreg.

[0003] Among the existing Chinese utility models, the publication number CN216338704U discloses a carbon fiber prepreg efficient cutting device, including a support mechanism, an operating mechanism is provided on one side of the support mechanism, and a clamping mechanism for fixing the carbon fiber prepreg is installed at the top of the operating mechanism, a cutting mechanism for cutting is provided at the top of the operating mechanism, and a driving mechanism for conveying the carbon fiber prepreg is provided at the top of the support mechanism. The utility model has a novel structure, and the device can quantitatively transmit the cloth, so that the length of the cloth cut each time is the same, avoiding the situation of inconsistent cutting size, and can avoid the situation that the cloth is scratched by the cutting knife due to pulling the cloth by hand.

[0004] Referring to the above-mentioned efficient cutting device for carbon fiber prepreg, the cutting device realizes quantitative transmission of carbon fiber prepreg through a driving mechanism, and compacts the carbon fiber prepreg through a compacting mechanism. However, in the process of transmitting the carbon fiber prepreg, it cannot be guaranteed that the carbon fiber prepreg delivered to the bottom of the cutting mechanism is free of wrinkles. Once the carbon fiber prepreg has wrinkles, the size of the carbon fiber prepreg after cutting will be deviated, thereby affecting the quality of the cutting of the carbon fiber prepreg. Therefore, how to better avoid wrinkles in the carbon fiber prepreg during cutting, which affects the cutting size, is an important issue that needs to be solved in the design of the carbon fiber prepreg cutting mechanism.

[0006] The utility model solves the above technical problems through the following technical solutions:

[0007] The utility model provides a carbon fiber prepreg cutting mechanism, comprising a support plate 1, and further comprising:

[0008] A carbon fiber prepreg fixing structure, wherein the carbon fiber prepreg fixing structure is arranged on the first support plate, and the carbon fiber prepreg fixing structure cuts and fixes the carbon fiber prepreg;

[0013] Preferably, two electric push rods are fixedly connected to the bottom side wall of the top plate, the bottom ends of the two electric push rods are fixedly connected to a push plate, and the bottom of the push plate is fixedly connected to a cutting knife.

[0014] In this technical solution, the electric push rod pushes the push plate to descend, and the push plate drives the pulling rope and the cutting knife to move, so that the cutting knife moves downward.

[0015] Preferably, a square groove and a cutting groove are provided on the side wall of the support plate 1, the cutting groove is located between two square grooves, and the cutting groove is located directly below the cutting knife.

[0016] In the technical solution, when the cutting knife is cutting the carbon fiber prepreg, it is prevented from directly hitting the side wall of the support plate, causing the cutting knife to become blunt.

[0017] Preferably, four support rods are fixedly connected to the bottom side wall of the support plate 2, and the support plate 3 is fixedly connected between the support rods.

[0018] In this technical solution, the support rod supports the support plate one, and the support plate three supports the sliding rod one.

As the sliding frame continues to move downward, the rotating plate rotates outward, and the friction pad rolls outward. During the rolling process, the friction pad appropriately pushes the carbon fiber prepreg to both sides, so that the wrinkles on the middle carbon fiber prepreg are flattened, until the sliding frame drives the fixed pad to rest against the side wall of the carbon fiber prepreg, thereby fixing the carbon fiber prepreg on both sides of the cutting groove.

[0023] Preferably, the shielding structure includes a shielding frame, two sliding rods, a pulling rope and two springs, the two sliding rods are fixedly connected between the side panels at equal distances, the two sliding rods are slidably connected to an "L"-shaped shielding frame, two springs are fixedly connected at equal distances between the shielding frame and the side panels, the position of the two sliding rods and the position of the electric push rod are staggered, one end of the pulling rope is fixedly connected to the side wall of the shielding frame, and the other end of the pulling rope passes through two rotating rollers and the top of the shielding frame and is fixedly connected to the side wall of the push plate.

[0025] On the basis of conforming to the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present utility model.

[0026] The positive and progressive effects of the utility model are:

[0027] 1. The shielding frame is used to shield the bottom of the cutting knife, and the cutting knife is shielded inside, so as to better prevent the cutting knife from being exposed to the outside, causing the worker to touch the cutting knife and get cut when manually pulling the carbon fiber prepreg cloth to move.

[0028] 2. The push plate is pushed down by the electric push rod, and the push plate drives the pulling rope and the cutting knife to move, and the cutting knife moves downward. At the same time, the pulling rope moves and pulls the shielding frame to move to both sides, and the second spring is compressed. The bottoms of the two shielding frames are separated, so that the shielding frame can be opened synchronously while the cutting knife descends.

[0029] 3. The sliding frame is pressed downward by the push plate. Once the spring is compressed, the friction pad contacts the carbon fiber prepreg first. The friction pad can increase the friction resistance between the friction pad and the carbon fiber prepreg. As the sliding frame continues to move downward, the friction pad rolls outward, and the carbon fiber prepreg can be properly pushed to both sides, so that the wrinkles on the middle carbon fiber prepreg are flattened, until the sliding frame drives the fixed pad to rest against the side wall of the carbon fiber prepreg, and fixes the carbon fiber prepreg on both sides of the cutting groove. At this time, the cutting knife synchronously cuts the carbon fiber prepreg between the two fixed pads, so as to better avoid wrinkles in the carbon fiber prepreg during cutting, which affects the cutting size.

[0049] A square groove 4 and a cutting groove 10 are provided on the side wall of the support plate 1 . The cutting groove 10 is located between two square grooves 4 . The cutting groove 10 is located directly below the cutting knife 14 .

[0050] When the cutting blade 14 is cutting the carbon fiber prepreg, it is prevented from directly hitting the side wall of the support plate 1, causing the cutting blade 14 to become blunt.

[0053] The carbon fiber prepreg fixing structure 8 includes a sliding frame 801, a fixing pad 802, a circular cavity 803, a sliding rod 804 and a spring 805. The sliding frame 801 is slidably connected in the square groove 4. The sliding rod 804 is fixedly connected between the support plate 1 and the support plate 3 7 at equal distances. The sliding rod 804 is slidably connected to the side wall at the bottom of the sliding frame 801. The spring 805 is fixedly connected between the side wall at the bottom of the sliding frame 801 and the support plate 1 at equal distances. Two circular cavities 803 are opened in the side wall at the top of the sliding frame 801. The fixing pad 802 is fixedly connected to the inner side wall at the top of the sliding frame 801.

[0054] The sliding frame 801 is located at two sides of the cutting groove 10 , and the sliding frame 801 is located below the pushing plate 15 .

[0055] The carbon fiber prepreg cloth fixing structure 8 includes a rotating plate 811, a rotating roller 812, a friction pad 813, a rotating rod 814, a torsion spring 815 and a fixed block 816. The rotating rod 814 passes through the circular cavity 803 and is rotatably connected to the side wall at the top of the sliding frame 801.

[0056] The sliding frame 801 moves downward, the spring 1 805 is compressed, and the friction pad 813 first contacts the carbon fiber prepreg. The friction pad 813 can increase the friction resistance between the carbon fiber prepreg and the sliding frame 801. As the sliding frame 801 continues to move downward, the rotating plate 811 rotates outward, and the friction pad 813 rolls outward. During the rolling process, the friction pad 813 appropriately pushes the carbon fiber prepreg to both sides, so that the wrinkles on the middle carbon fiber prepreg are flattened, until the sliding frame 801 drives the fixed pad 802 to rest on the side wall of the carbon fiber prepreg, and the carbon fiber prepreg on both sides of the cutting groove 10 is fixed.

[0057] The shielding structure 9 includes a shielding frame 901, a sliding rod 902, a pulling rope 903 and a spring 904. The sliding rod 902 is fixedly connected between the side panels 6 at equal distances. The sliding rod 902 is slidably connected to the "L"-shaped shielding frame 901.

[0058] The shielding frame 901 blocks the bottom of the cutting knife 14 and shields the cutting knife 14 inside, which can better prevent the cutting knife 14 from being exposed to the outside, causing the worker's hand to touch the cutting knife 14 and get cut when manually pulling the carbon fiber prepreg cloth to move. When the pulling rope 903 moves, it will pull the shielding frame 901 to move to both sides. The shielding frame 901 slides on the sliding rod 2 902, the spring 2 904 is compressed, and the bottoms of the two shielding frames 901 are separated. When the cutting knife 14 descends, the shielding frame 901 can be opened synchronously.

[0059] When the utility model is in use, the electrical components in the present application are all connected to an external power source and a control switch, the carbon fiber prepreg is placed on the support plate 1, and the shielding frame 901 shields the bottom of the cutting knife 14, shielding the cutting knife 14 inside, which can better prevent the cutting knife 14 from being exposed to the outside, causing the worker to touch the cutting knife 14 and get cut when manually pulling the carbon fiber prepreg to move;

[0060] When cutting, the electric push rod 13 is started, and the electric push rod 13 pushes the push plate 15 to descend, and the push plate 15 drives the pull rope 903 and the cutting knife 14 to move, and the cutting knife 14 moves downward. At the same time, the pull rope 903 moves to pull the shielding frame 901 to move to both sides, and the shielding frame 901 slides on the sliding rod 902, and the spring 904 is compressed, and the bottoms of the two shielding frames 901 are separated. When the cutting knife 14 descends, the shielding frame 901 can be opened synchronously;

[0061] When the push plate 15 is against the top of the sliding frame 801, the push plate 15 then descends to press the sliding frame 801 to move downward, the spring 805 is compressed, and the friction pad 813 first contacts the carbon fiber prepreg. The friction pad 813 can increase the friction resistance between the carbon fiber prepreg and the carbon fiber prepreg. As the sliding frame 801 continues to move downward, the rotating plate 811 rotates outward, and the friction pad 813 rolls outward. During the rolling process, the friction pad 813 appropriately pushes the carbon fiber prepreg to both sides, so that the wrinkles on the middle carbon fiber prepreg are flattened, until the sliding frame 801 drives the fixed pad 802 to press against the side wall of the carbon fiber prepreg, fixing the carbon fiber prepreg on both sides of the cutting groove 10. At this time, the cutting knife 14 synchronously cuts the carbon fiber prepreg between the two fixed pads 802, so as to better avoid wrinkles in the carbon fiber prepreg during cutting, which affects the cutting size.
