Since the device is used, the function of stretching the fabric longitudinally and transversely can achieve a flatter effect of the fabric. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a tensioning device for carbon fiber grid cloth is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A tensioning device for carbon fiber grid cloth includes a bracket and a telescopic mechanism. The telescopic mechanism is arranged inside the bracket. A winding roller is arranged at one end of the bracket. One end of the winding roller is drivingly connected with a motor. Width stretching mechanisms and length stretching mechanisms are respectively arranged at both ends of the telescopic mechanism.

[0008] The width stretching mechanism includes a square box and power rollers. The power rollers are rotatably connected to the inner walls on both sides of the square box. The linear rotation direction of the power rollers forms an angle with the linear movement direction of the grid cloth. The length stretching mechanism includes a first pressing wheel and a second pressing wheel. Both ends of the second pressing wheel are fixedly connected to the inside of the bracket. Both ends of the first pressing wheel are rotatably connected to the telescopic mechanism.

[0015] Compared with the prior art, the utility model provides a tensioning device for carbon fiber mesh cloth, which has the following beneficial effects:

[0016] 1. For the tensioning device for carbon fiber mesh cloth, the cloth is wound by the winding roller driven by the motor. The telescopic mechanism enables the width stretching mechanism and the length stretching mechanism to clamp the mesh cloth. Under the action of the power roller, there is an outward pulling force on the cloth, so that the width of the mesh cloth is stretched before winding. At the same time, under the action of the rotational damping mechanism, the first pressing wheel and the second pressing wheel make the transmission speed of the mesh cloth lower than the transmission speed of the power roller for the cloth, so that the mesh cloth is stretched in width and length while being wound, making the mesh cloth flatter.

[0017] 2. For the tensioning device for carbon fiber mesh cloth, by setting the telescopic mechanism, the length stretching mechanism and the width stretching mechanism can synchronously press the mesh cloth, so that the mesh cloth will not be stretched singly during stretching, improving the leveling quality of the mesh cloth.

[0018] 3. For the tensioning device for carbon fiber mesh cloth, by setting the oil pump, by controlling the rotation speed of the oil pump, the friction force between the caliper and the brake disc can be controlled, so as to control the conveying speed of the mesh cloth when the mesh cloth is pressed by the first pressing wheel and the second pressing wheel, and thus the stretching force of the mesh cloth in length can be adjusted.

[0019] The parts not involved in this device are the same as the prior art or can be implemented using the prior art. The structure of this utility model is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 of the embodiments.

[0027] A tensioning device for carbon fiber mesh cloth, as Figure 1 shown, includes a bracket 2 and a telescopic mechanism 4. The telescopic mechanism 4 is arranged inside the bracket 2. One end of the bracket 2 is provided with a winding roller 1, and one end of the winding roller 1 is drivingly connected to a motor 20;

[0028] Both ends of the telescopic mechanism 4 are respectively provided with a width stretching mechanism 3 and a length stretching mechanism 5;

[0029] As Figure 2As shown, the width stretching mechanism 3 includes a square box 6 and a power roller 7. The power roller 7 is rotatably connected to the inner walls on both sides of the square box 6, and there is an included angle between the linear rotation direction of the power roller 7 and the linear movement direction of the mesh cloth.

[0030] As Figure 3 shown, the length stretching mechanism 5 includes a first pressing wheel 14 and a second pressing wheel 15. Both ends of the second pressing wheel 15 are fixedly connected to the inside of the bracket 2; both ends of the first pressing wheel 14 are rotatably connected to the telescopic mechanism 4.

[0031] A rotation damping mechanism 21 is provided at one end of the first pressing wheel 14 and the second pressing wheel 15.

[0032] During use, the winding roller 1 winds the cloth driven by the motor 20. The telescopic mechanism 4 makes the width stretching mechanism 3 and the length stretching mechanism 5 clamp the mesh cloth. Under the action of the power roller 7, there is an outward pulling force on the cloth, so that the width of the mesh cloth is stretched before winding. At the same time, under the action of the rotation damping mechanism 21, the transmission speed of the first pressing wheel 14 and the second pressing wheel 15 for the mesh cloth is lower than the transmission speed of the power roller 7 for the cloth. Thus, while the mesh cloth is being wound, its width and length are stretched, making the mesh cloth flatter.

[0033] As Figure 4 shown, the telescopic mechanism 4 includes a connecting rod 10 and a gantry 11. Both ends of the gantry 11 are fixedly connected to the upper side of the bracket 2. The lower surface of the top of the gantry 11 is fixedly connected with a telescopic rod 12, and the telescopic end of the telescopic rod 12 is fixedly connected with a support plate 13.

[0034] One end of the connecting rod 10 is fixedly connected to the side surface of the square box 6;

[0035] The other end of the connecting rod 10 is fixedly connected to the rotating shaft of the first pressing wheel 14.

[0036] As Figure 2 shown, both ends of the connecting rod 10 are fixedly connected with sliders 8, and the sliders 8 are slidably connected to the bracket 2 through a 9 opened on the inner side of the bracket 2.

[0037] In this device, by providing the telescopic mechanism 4, the length stretching mechanism 5 and the width stretching mechanism 3 are synchronously pressed against the mesh cloth, so that the mesh cloth will not be stretched singly during stretching, improving the leveling quality of the mesh cloth.

[0038] As Figure 5 shown, the rotation damping mechanism 21 includes a brake disc 19 and an oil pump 16. The brake disc 19 is fixedly connected to one end of the first pressing wheel 14 and the second pressing wheel 15. The brake disc 19 is rotatably connected with a caliper 18. One side of the caliper 18 is provided with an oil pipe 17, and the caliper 18 is connected and communicated with the oil pump 16 through the oil pipe 17.

[0039] In this device, an oil pump 16 is provided. By controlling the rotation speed of the oil pump 16, the friction force between the caliper 18 and the brake disc 19 is controlled, so as to control the conveying speed of the mesh fabric when the mesh fabric is clamped by the first pressing wheel 14 and the second pressing wheel 15, and thus the stretching force of the mesh fabric in the length direction can be adjusted.

[0040] Working principle: The winding roller 1 winds the fabric driven by the motor 20. The telescopic mechanism 4 enables the width stretching mechanism 3 and the length stretching mechanism 5 to clamp the fabric. Under the action of the power roller 7, an outward pulling force is applied to the fabric, so that the mesh fabric is stretched in width before winding. At the same time, under the action of the rotation damping mechanism 21, the first pressing wheel 14 and the second pressing wheel 15 make the conveying speed of the mesh fabric lower than the conveying speed of the fabric by the power roller 7.

[0041] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
