DETAILED DESCRIPTION
[0024] The carbon fiber yarn spreading creel in the preparation of the carbon fiber prepreg of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0025] like Figures 1 to 7As shown: a carbon fiber yarn spreading frame in the preparation of carbon fiber prepreg, including a supporting long rod 13, a supporting vertical rod 9, two yarn spreading frames 2, four supporting vertical plates 4, an arc-shaped long plate 12 and a cross bottom plate 8, a supporting long plate 6 is fixedly installed on the top of the supporting vertical rod 9, and a door-shaped plate 5 is fixedly installed on the left, bottom and right sides of the supporting long plate 6, and an arc-shaped long groove 10 is opened on the front and rear sides of the supporting vertical rod 9, the yarn spreading frame 2 is fixedly connected to the supporting long rod 13, and a supporting shaft 21 is fixedly connected between the two supporting vertical plates 4 and between the other two supporting vertical plates 4, and the internal thread of the supporting vertical plate 4 is connected with a bolt 3, and the bolt 3 is threadedly connected to the yarn spreading frame 2, and the number of bolts 3 is four, and the arc-shaped long plate 12 is movable with the arc-shaped long groove 10 The top of the cross bottom plate 8 is fixedly mounted on the bottom of the supporting upright 9. Through the arrangement of the first supporting assembly and the supporting upright 9, the first supporting assembly can support the supporting upright 9, so that the device can be supported. Through the arrangement of the supporting long plate 6, the door-shaped plate 5, the yarn spreading assembly, the folding assembly and the limiting assembly, the yarn spreading assembly can unfold the carbon fiber yarn, the folding assembly can fold the yarn spreading assembly, and the limiting assembly can limit the yarn spreading assembly. When the carbon fiber yarn torn from the carbon fiber tube is placed on the device for yarn spreading operation, the device can compress the carbon fiber yarn to prevent the carbon fiber yarn from stacking due to not being compressed, so that the device can improve the yarn spreading effect.
[0026] When in use, the cross bottom plate 8 and the supporting uprights 9 can support the device. The initial state of the device is: the bolt 3 is threadedly connected to the yarn spreading frame 2, and the limiting long rod 17 is located at the topmost inside the limiting long hole 15. During the preparation of the carbon fiber prepreg, when it is necessary to use the device to spread the carbon fiber yarn torn from the carbon fiber tube, the carbon fiber yarn torn from the carbon fiber tube is moved, and the carbon fiber yarn torn from the carbon fiber tube is placed on the supporting long plate 6 and the two yarn spreading frames 2 and the carbon fiber yarn is passed between the two yarn spreading frames 2 and the two yarn pressing frames 19. At this time, the carbon fiber yarn can be placed on the supporting long plate 6 and the two yarn spreading frames 2 for unfolding, and the device can be used to spread the carbon fiber yarn torn from the carbon fiber tube. When using the device to spread the carbon fiber yarn, the carbon fiber yarn torn from the carbon fiber tube is placed After the device is installed, the two holding columns 18 are rotated at the same time, so that the holding columns 18 and the supporting columns 23 are rotated along the L-shaped long plate 11, and the threaded shaft 16 and the tapered column 20 are rotated along the supporting long rod 13. Under the action of the threaded transmission, the limiting long rod 17 moves downward along the threaded shaft 16, and the limiting long rod 17 slides along the limiting long hole 15, and the limiting vertical plate 22 slides along the limiting long groove 14, and the pressing yarn frame 19 slides along the L-shaped long plate 11, and the convex plate 7 slides along the convex long groove 1. When the pressing yarn frame 19 presses the carbon fiber yarn, the two holding columns 18 are stopped from rotating at the same time. At this time, the carbon fiber yarn can be prevented from stacking. In this process, when the carbon fiber yarn torn off the carbon fiber tube is placed on the device for yarn spreading operation, the device can press the carbon fiber yarn, so that the carbon fiber yarn can be prevented from stacking due to not being pressed, so that the device can improve the yarn spreading effect.
[0027] like Figures 1 to 7As shown: a carbon fiber yarn spreading frame in the preparation of carbon fiber prepreg, including a supporting long rod 13, a supporting upright rod 9, a threaded shaft 16 and an L-shaped long plate 11, the top of the supporting upright rod 9 is fixedly installed with a supporting long plate 6, the left side, bottom and right side of the supporting long plate 6 are commonly fixedly installed with a door-shaped plate 5, the bottom of the threaded shaft 16 is fixedly connected with a conical column 20, the outer surface of the threaded shaft 16 is threadedly connected with a limiting long rod 17, the left and right sides of the limiting long rod 17 are fixedly connected with a limiting upright plate 22, one side of the limiting long rod 17 is fixedly connected with a yarn pressing frame 19, one side of the yarn pressing frame 19 is fixedly connected with a convex plate 7, the top of the threaded shaft 16 is fixedly connected with a supporting column 23, and the top of the supporting column 23 is fixedly connected with a holding column 18 The number of holding columns 18 and the number of yarn pressing frames 19 are both two, the number of L-shaped long plates 11 is two, a limited long hole 15 is provided inside the L-shaped long plate 11, and the left inner wall and the right inner wall of the limited long hole 15 are both provided with a limited long groove 14, and a convex long groove 1 is provided on the inner side of the L-shaped long plate 11. By setting the supporting long rod 13, the clamping assembly and the second supporting assembly, the clamping assembly can clamp the carbon fiber yarn, and the second supporting assembly can support the clamping assembly. After the use of the device is completed, when the device needs to be stored, the top of the device can be folded, so that the device can avoid occupying a large storage space due to the top of the device being unable to be folded, so that the device can be conveniently stored.
[0028] During use, after the use of the device is completed, when the device needs to be stored, the four bolts 3 are rotated at the same time to disconnect the bolts 3 from the yarn display frame 2, and the two L-shaped long plates 11 are rotated at the same time to rotate the yarn pressing frame 19, the L-shaped long plates 11 and the supporting long rods 13, so that the yarn display frame 2 rotates along the supporting long plates 6, the door-shaped plates 5 and the supporting shafts 21 respectively. When the two L-shaped long plates 11 are rotated to the maximum angle at the same time, the yarn display frame 2 and the supporting long rods 13 are in contact with the supporting uprights 9 and the arc-shaped long plates 12 enter the arc-shaped long grooves 10. At this time, the yarn display frame 2 can be folded, and the device can be stored at this time. In the process of storing the device, the top of the device can be folded, so that the device can avoid occupying a larger storage space due to the inability to fold the top of the device, so that the device can be conveniently stored.
