Description

Technical Field

[0001] The utility model belongs to the technical field of carbon fiber tube manufacturing and relates to a tube winding machine with uniform force on each winding layer. Background Art

[0002] Carbon fiber tube, also known as carbon fiber tube or carbon tube, is a tubular material made of carbon fiber composite material pre-impregnated with styrene-based polyester resin and then heated, cured and pulled (wrapped). The manufacturing process of carbon fiber tube mainly includes tube rolling process and pultrusion process. The tube rolling process is to hot roll the carbon fiber prepreg on the tube rolling machine, while the pultrusion process is to pultrude the carbon fiber composite material into a tube of the desired shape through a mold. Carbon fiber tube has become an indispensable high-performance material in modern industry due to its unique material properties and wide range of applications. In the manufacturing process of carbon fiber tube, if the carbon fiber material is improperly bonded to the winding or cannot be bonded, it will cause a series of serious problems, thus affecting the performance, quality and even the overall manufacturing efficiency of the product.

[0003] Poor lamination will significantly reduce the structural strength of the carbon fiber tube. The high strength of the carbon fiber tube mainly comes from the close arrangement and interlayer bonding of the carbon fiber material. If the carbon fiber material is not tightly attached to the winding, gaps or dislocations will appear between the layers, resulting in uneven force, which is very likely to cause stress concentration in the local area, thus affecting the bearing capacity of the entire tube. Therefore, a tube winding machine with uniform force on each layer of the winding is urgently needed to solve the above problems. Utility Model Content

[0037] See also Figure 1-Figure 4, as the first embodiment of the utility model: in order to solve the problem that poor fitting will cause the structural strength of the carbon fiber tube to be significantly reduced. The high strength of the carbon fiber tube mainly comes from the close arrangement and interlayer bonding of the carbon fiber material. If the carbon fiber material is not tightly fitted to the winding, gaps or misalignments will appear between the layers, resulting in uneven force, which is very likely to cause stress concentration locally, thereby affecting the bearing capacity of the entire tube. First, the staff will place the pipe body 180 that needs to be wrapped with carbon fiber material between the two sets of side clamping parts 190 and inside the two sets of support rollers 200. When the pipe body 180 needs to be wrapped with carbon fiber material, first, the moving screw 120 is used to drive the moving seat 110 to move to the right, and the moving seat 110 is used to drive the motor 100 and the rotating rod 1 50 and the tube support component 160 move to the right, so that several groups of side support rollers 16e on the outside of the tube support component 160 support the tube body 180, and drive the tube body 180 to rotate through the rotary rod 150 and the two groups of support rollers 200. Subsequently, when the tube body 180 rotates and wraps the carbon fiber material, its several groups of side force rollers 19c are supported by several groups of side support rods 19d, and the side force rollers 19c are fitted with the outside of the tube body 180, thereby keeping the carbon fiber material evenly stressed and fitting with the outside of the tube body 180.

[0038] See also Figure 1-Figure 4 , as the second embodiment of the utility model: based on the description in the above embodiment, further, since three groups of shear frames 16c for supporting the support frame 16d are provided on the outside of the movable sleeve 16b, the cross-section of the shear frame 16c is an X-shaped structure, and the middle position of the shear frame 16c is a rotation damper for active support. When the pipe support component 160 moves to the inside of the pipe body 180, its spring 16a and rotation damper can always maintain the tension of the shear frame 16c and the movable sleeve 16b, so that the side support roller 16e can fit the inside of the pipe body 180 and make the rotation of the pipe body 180 stable.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
