[0030] In order to enable those skilled in the art of this technology to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] As Figures 1 to 3 shown, a carbon fiber fabric auxiliary unwinding device in an embodiment of the present utility model includes an adjustable bracket, a transmission structure, and an adjustable support assembly 6. The transmission structure is fixedly connected to the lower end of the adjustable bracket, and the adjustable support assembly 6 is installed at the upper end of the adjustable bracket, and can be adjusted according to the different widths of the carbon fiber fabric and the height of the loom winding system to meet the unwinding requirements of different loom models.

[0032] As Figures 1 to 3 shown, the adjustable bracket includes a first connecting rod 1. The first connecting rod 1 is provided with a through hole 101, and the through hole 101 is opened along the length direction of the first connecting rod 1. By opening the through hole 101, the first connecting rod 1 becomes a hollow connecting rod. A pair of L-shaped connecting rods 4 are slidably connected to the first connecting rod 1, and the pair of L-shaped connecting rods 4 are respectively slidably connected to both ends of the first connecting rod 1. By slidably connecting the L-shaped connecting rods 4 in the first connecting rod 1, the length of the adjustable bracket can be increased so that the auxiliary unwinding device can meet carbon fiber fabrics of different widths.

[0033] Specifically, as Figures 1 to 3As shown in the figure, a plurality of first threaded holes 102 matching the L-shaped connecting rod 4 are provided on the side wall of the through hole 101. A second locking handle 15 matching the first threaded hole 102 is threadedly connected to the first connecting rod 1. By threadedly connecting the second locking handle 15 into the first threaded hole 102, one end of the second locking handle 15 can abut against one side wall of the L-shaped connecting rod 4, so as to increase the frictional force between the outer wall of the L-shaped connecting rod 4 and the inner wall of the through hole 101, and realize the locking of the first connecting rod 1 and the L-shaped connecting rod 4.

[0034] As Figures 1 to 3 shown in the figure, the transmission structures are respectively fixedly connected to the lower ends of the first connecting rod 1 and the L-shaped connecting rod 4. Even if the first connecting rod 1 and the L-shaped connecting rod 4 slide relative to each other, the stability of the movement of the auxiliary uncoiling device can be largely ensured. Among them, the transmission structure includes a plurality of first casters 2 and a plurality of second casters 5. In this embodiment, the number of the first casters 2 and the second casters 5 is two. The two first casters 2 are respectively fixedly connected to both sides of the first connecting rod 1, and the two second casters 5 are fixedly connected to the end of the L-shaped connecting rod 4 away from the first connecting rod 1, and the adjustable support assembly 6 is located above the second caster 5. With such a setting, most of the weight of the carbon fiber fabric is supported by the adjustable bracket at the end close to the second caster 5, which can minimize the pressure provided by the carbon fiber fabric at the bending part of the L-shaped connecting rod 4. Even if the width of the adjustable bracket is adjusted to the maximum width, the adjustable bracket can still walk smoothly, which is beneficial to meeting carbon fiber fabrics of different widths, while the first casters 2 play an auxiliary walking role.

[0035] As Figure 6 shown in the figure, as Figures 1 to 5 shown in the figure, the adjustable support assembly 6 includes a second connecting rod 7. A first sliding groove 701 is provided on the upper end surface of the second connecting rod 7. A third connecting rod 8 matching the first sliding groove 701 is slidably connected to the second connecting rod 7. A support structure 11 is installed at the upper end of the third connecting rod 8. The third connecting rod 8 has a first contact surface 801 and a second contact surface 802. A plurality of vertically distributed positioning holes 8011 are provided on the first contact surface 801. A second threaded hole 702 matching the positioning holes 8011 is provided on the side wall of the second connecting rod 7. A first locking handle 10 matching the second threaded hole 702 is threadedly connected to the second connecting rod 7. One end of the first locking handle 10 passes through the second threaded hole 702 and is threadedly connected to one of the positioning holes 8011. By sliding the positioning holes 8011 up and down, the first locking handle 10 is fixed in different positioning holes 8011, so as to realize the fixation of the first contact surface 801 at different heights.

[0036] The positioning hole 8011 can be used as a frequently used preset height. When encountering another height that is not frequently used, the surface of the third connecting rod 8 can be flipped over so that the second contact surface 802 contacts the side of the second connecting rod 7 where the second threaded hole 702 is opened. The first locking handle 10 is threadedly connected to the second threaded hole 702, and one end of the first locking handle 10 is against the second contact surface 802. The friction between the first contact surface 801 and the inner wall of the first slide groove 701 is increased to lock the third connecting rod 8, thereby realizing stepless adjustment of the third connecting rod 8 in the second connecting rod 7, which is beneficial for the adjustable support assembly 6 to adapt to loom winding systems of different heights.

[0037] like Figures 1 to 5 As shown, the support structure 11 includes an arc-shaped support member 9, which is fixedly connected to the upper end of the first contact surface 801 and matches the carbon fiber fabric, thereby fixing the carbon fiber fabric and avoiding as much as possible the carbon fiber fabric from being separated from the auxiliary unloading device during movement.

[0038] like Figures 1 to 5 As shown, a handle 3 is fixedly connected to the upper end of the first caster 2, and the auxiliary unloading device is pushed by manually pushing the handle 3, which is beneficial for pushing the carbon fiber fabric to the next process.

[0039] When the auxiliary unloading device is used, it is necessary to first confirm the width of the carbon fiber fabric, and then loosen the second locking handle 15 in the first threaded hole 102, and pull the L-shaped connecting rod 4 to the end away from the first connecting rod 1, or push the L-shaped connecting rod 4 to the end close to the first connecting rod 1, so that the auxiliary unloading device can match the width of the carbon fiber fabric. After the L-shaped connecting rod 4 is adjusted, the second locking handle 15 can be tightened. Then confirm the height of the loom winding system, slide the third connecting rod 8 up and down in the second connecting rod 7 according to the height of the loom winding system, so that the third connecting rod 8 is in a position that matches the height of the loom winding system, and then fix the third connecting rod 8 by tightening the first locking handle 10. After the adjustable support assembly 6 and the adjustable bracket are adjusted, the unloading operation can be carried out. When the carbon fiber fabric is located on the auxiliary unloading device, the auxiliary unloading device is pushed to the next process by pushing the handle 3 to drive the transmission structure.

[0040] In another embodiment, if Figures 6 to 9 As shown, the support structure 11 includes a support plate 12, on which a convex groove 1201 is provided, and a pair of semi-arc support members 13 matching the convex groove 1201 are slidably connected to the support plate 12, and a card slot is formed between the two semi-arc support members 13, and one end of the carbon fiber fabric can be placed in the card slot. The semi-arc support member 13 slides in the convex groove 1201, and the size of the card slot can be changed to accommodate carbon fiber fabrics of more specifications.

[0041] As shown Figures 6 to 9 in the figure, a waist-shaped hole 1202 is formed in the side wall of the convex groove 1201. A fourth connecting rod 14 is installed on the support plate 12. One end of the fourth connecting rod 14 passes through the waist-shaped hole 1202 and is rotatably connected to the semi-circular support member 13. A limiting block 1401 is fixedly connected to the fourth connecting rod 14, and an annular groove 1203 matching the limiting block 1401 is formed in the inner wall of the waist-shaped hole 1202. When the positions of the limiting block 1401 and the annular groove 1203 correspond to each other, by rotating the fourth connecting rod 14, the limiting block 1401 can be located in the annular groove 1203. At this time, the semi-circular support member 13 cannot continue to slide in the convex groove 1201, realizing the adjustment and quick locking of the semi-circular support member 13.

[0042] As shown Figure 7 in the figure, in order to further extend the service life of the auxiliary unwinding device, a slider 16 is fixedly connected to the lower end of the support structure 11. A second sliding groove 803 matching the slider 16 is formed in the upper end surface of the third connecting rod 8, and a spring 17 is installed between the bottom wall of the second sliding groove 803 and the slider 16. When the carbon fiber fabric is placed on the support structure 11, the second sliding groove 803 can absorb part of the gravity of the falling carbon fiber fabric, so as to reduce the gravity on the transmission structure and the adjustable bracket, which is beneficial to extending the service life of the auxiliary unwinding device.

[0043] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
