[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0035] like Figures 1 to 4 As shown, a composite fiber material fixing and clamping mechanism comprises an adjusting portion 4 and a support platform 1 arranged relatively on the adjusting portion 4, the adjusting portion 4 is used to adjust the distance between the two support platforms 1, a support seat 2 is fixedly arranged on the support platform 1, and the inner walls of the support platform 1 and the support seat 2 are surrounded to form a limiting cavity 5, and the composite fiber material fixing and clamping mechanism also includes:

[0036] A clamping portion 3 is provided in the limiting cavity 5 and is used for clamping and fixing the composite fiber material.

[0037] The clamping portion 3 comprises.

[0038] The supporting legs 31 are relatively fixed on the supporting platform 1 .

[0039] A telescopic cylinder 32 is fixed to the top of the inner wall of the limiting cavity 5.

[0040] A plurality of clamping plates 33 are provided between the telescopic cylinder 32 and the supporting leg 31, and the optimal number of the clamping plates 33 is four. When the number of the clamping plates 33 is less than four, the clamping and fixing effect on the composite fiber material is relatively poor. When the number of the clamping plates 33 is more than four, although the clamping and fixing effect on the composite fiber material is better, there are more clamping and fixing parts for the composite fiber material, which has a greater impact on the overall stretching efficiency of the composite fiber material.

[0041] A plurality of telescopic members 34 are disposed on both sides of the clamping plate 33 and are used to link two adjacent clamping plates 33 to move closer to or farther from each other.

[0042] The four clamping plates 33 are arranged in order from top to bottom, namely, the first plate, the second plate, the third plate and the fourth plate. The first plate, the second plate, the third plate and the fourth plate are used to refer to the clamping plates 33 at different positions. When clamping and fixing the composite fiber material, one side of the composite fiber material is first passed through between the second plate and the third plate in a horizontal state, and penetrates a certain distance into the limiting cavity 5, then turns around and passes through between the third plate and the fourth plate, and then turns around and passes through the bottom of the fourth plate into the limiting cavity 5, and then pulls it upward to make it pass between the first plate and the second plate. The operator then pulls it by hand, and finally starts the telescopic cylinder 32 to make it Push one plate downward, and through the linkage of the telescopic member 34, the first plate, the second plate, and the third plate are moved downward at the same time, and the distance between the two adjacent clamping plates 33 is shortened until the composite fiber material is clamped and fixed. The clamping and fixing operation of the composite fiber material can be completed, so that the composite fiber material is wound in S and C shapes between the clamping plates 33. Through multi-point folding, the horizontal friction between the composite fiber material and the clamping plates 33 is increased, and the downward pressure applied by the telescopic cylinder 32 is cooperated to improve the clamping and fixing effect of the composite fiber material, so as to facilitate the normal progress of the subsequent stretching operation.

[0043] In this embodiment, the telescopic member 34 includes:

[0044] A scissor-type telescopic frame 345 is hingedly disposed between the two clamping plates 33 .

[0045] The connecting shaft 344 disposed on the scissor-type telescopic frame 345 is rotated, and one end of the connecting shaft 344 passes through the outer through slot 342 disposed on the clamping plate 33 .

[0046] The inner slide groove 341 is disposed in the outer through groove 342 .

[0047] The slider 343 is slidably disposed in the inner slide groove 341 , and the slider 343 is fixedly connected to the connecting shaft 344 .

[0048] After the composite fiber material is wound between the four clamping plates 33, the telescopic cylinder 32 is controlled to push one plate downward, so that the scissor-type telescopic frames 345 between the first plate and the second plate, the second plate and the third plate, and the third plate and the fourth plate are synchronously contracted in the vertical direction, and the slider 343 is pushed from one end of the inner slide groove 341 close to the hinge point of the scissor-type telescopic frame 345 to the other end of the inner slide groove 341, so as to achieve the effect of synchronously approaching or moving away from the four clamping plates 33, until the free end of the telescopic cylinder 32 can no longer be extended, the clamping and fixing operation of the reset fiber material is completed, and the telescopic cylinder 32 is controlled to shorten to achieve the relaxation of the composite fiber material, so as to facilitate the replacement of new composite fiber material.

[0049] In this embodiment, the opening of the outer through groove 342 is smaller than the opening of the inner slide groove 341, and the outer through groove 342 is relatively distributed with the hinge points of the scissors-type telescopic frame 345 and the clamping plate 33. Such a design can effectively limit the slider 343 in the inner slide groove 341 to constrain its freedom so that it can only slide linearly in the inner slide groove 341, thereby ensuring the stability of the operation of the scissors-type telescopic frame 345.

[0050] In this embodiment, the surfaces on the clamping plate 33 adjacent to the telescopic member 34 are both semicircular surfaces, and the surface between the two semicircular surfaces on the clamping plate 33 is a horizontal surface. This design facilitates the winding of the two sides of the composite fiber material in an S- and C-shape between the two groups of multi-layer clamping plates 33, and makes the contact surfaces between the clamping plate 33 and the composite fiber material both plane and arc surfaces, so that when the composite fiber material is stretched, the parts where the composite fiber material is clamped and fixed can be well protected, the clamping protection of the composite fiber material can be improved, and the contact area between the composite fiber material and the clamping plate 33 can be increased, thereby achieving the effect of increasing friction, and cooperating with the downward pressure of the clamping plate 33 on the composite fiber material, the clamping and fixing effect of the composite fiber material is greatly improved to prevent it from loosening and affecting the stretching effect of the composite fiber material.

[0051] In this embodiment, the free end of the telescopic cylinder 32 is fixedly connected to the top of the adjacent clamping plate 33, and the top of the support leg 31 is fixedly connected to the bottom of the adjacent clamping plate 33. This design allows the second, third and fourth plates to be pulled synchronously after one plate is pulled by the telescopic cylinder 32, so that the four clamping plates 33 can move synchronously, so as to clamp, fix or loosen and replace the composite fiber material.

[0052] In this embodiment, the adjustment unit 4 includes:

[0053] A bearing seat 41 is used for supporting the support platform 1 , and a limiting groove 42 is provided on the top of the bearing seat 41 .

[0054] The screw rod 43 disposed in the limiting groove 42 is rotated, and the threads at both ends of the screw rod 43 are in opposite directions.

[0055] The nut seat 44 is threadedly sleeved on the screw rod 43 , and the top of the nut seat 44 is fixedly connected to the bottom of the support platform 1 .

[0056] The driving member 45 for driving the screw rod 43 to rotate can be a driving motor, which directly drives the screw rod 43 to rotate, so as to facilitate the control of the two support platforms 1 to move closer to or away from each other, to facilitate the disassembly and replacement of the composite fiber material, or to facilitate the stretching of the composite fiber material.

[0057] The above description is only the preferred embodiment of the utility model, and the parts not described in the utility model can be implemented by adopting or drawing on existing technologies. Of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples. The changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the utility model should also fall within the protection scope of the utility model.
