Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber prepreg molding, in particular to an anti-wrinkle carbon fiber prepreg pultrusion preforming device. Background Art

[0002] Carbon fiber prepreg is a composite material made by compounding epoxy resin on carbon fiber through high pressure and high temperature technology. It is made of carbon fiber yarn, epoxy resin, release paper and other materials, and processed through coating, hot pressing, cooling, laminating, winding and other processes. It is also called carbon fiber prepreg cloth. A pultrusion preforming device is required in the process of carbon fiber prepreg molding.

[0003] For example, the utility model with application number CN202322328147.0 discloses a carbon fiber prepreg pultrusion preforming device. The utility model forms irregular materials into a circular shape by inputting the pre-rolling component, and then forming them in sections by multiple rolling forming components at the rear end. This operation can improve the compaction quality and reduce the hollow rate in the formed R angle strip and the wrinkle rate of the outer surface. However, in the actual use of the device, since the cross-sectional shape of the prepreg changes from a circle to a triangle and is then pulled and extruded into an R angle, when the cross-sectional shape of the carbon fiber prepreg changes and the area decreases, its overall length increases. At the same time, the multiple rolling forming components of the device make the overall rotation speed consistent through gears, so the overlong carbon fiber prepreg will gradually accumulate between the two rollers to form a loose state, resulting in a relatively general problem of the overall anti-wrinkle effect.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a wrinkle-proof carbon fiber prepreg pultrusion preforming device is provided. Utility Model Content

One side of the driving gear is meshed with the driven gear 1, and one side of the driven gear 1 is meshed with the double gear 1. The front end of the double gear 1 is connected to the pressure roller 2 via a rotating shaft.

[0010] Furthermore, the forming assembly also includes a driven gear 2, a double gear 2, a pressure roller 3 and an idler roller 2, one side of the double gear 1 is meshed with the driven gear 2, and the double gear 2 is arranged on one side of the driven gear 2, the front end of the double gear 2 is connected to the pressure roller 3 through a rotating shaft, and the bottom of the pressure roller 3 and the pressure roller 2 are both arranged with an idler roller 2.

[0011] Furthermore, an adjustment component is provided inside the chassis, and the adjustment component includes an electric push rod 1 and an adjustment gear 1. The internal rotation of the driven gear 1 is connected to the electric push rod 1, and the front end of the electric push rod 1 is connected to the adjustment gear 1.

[0012] Furthermore, the diameter of the driven gear 1 is smaller than the diameter of the adjusting gear 1, and the width of the driven gear 1 is smaller than the width of the driving gear.

[0014] The utility model provides a wrinkle-proof carbon fiber prepreg pultrusion preforming device, which has the following beneficial effects:

[0015] 1. The utility model can use the electric lifting rod to make the roller on the roller seat fit with the carbon fiber prepreg and tighten it through the setting of the tensioning assembly. At the same time, the pressure sensor is used to detect the pressure during tightening to avoid deformation caused by excessive pressure. The spring seat can also be used to increase the tolerance during adjustment. Therefore, when the middle part of the prepreg becomes longer after pultrusion preforming, it can also be automatically tensioned. The guide rod can also limit and guide the roller seat and the mounting plate, which is conducive to improving its stability during movement.

[0016] 2. The utility model sets an adjustment component. When the electric push rod 1 contracts, the adjustment gear 1 will mesh with the double gear 1, and the driven gear 1 will separate from the double gear 1. Since the size of the adjustment gear 1 is larger than that of the driven gear 1, the acceleration structure can be used to increase the rotation speed of the pressure roller 2 to process the excessively long portion of the carbon fiber prepreg. Similarly, when the electric push rod 2 extends, the double gear 2 is switched from the driven gear 2 to the adjustment gear 2 to increase the rotation speed of the pressure roller 3, thereby reducing the excessively long carbon fiber prepreg in the middle.

[0023] like Figure 2 As shown, the chassis 1 is provided with an adjustment component 5 inside, and the adjustment component 5 includes an electric push rod 1 501 and an adjustment gear 1 502.

Then, when the middle part of the carbon fiber prepreg becomes longer after pultrusion preforming, the pressure detected by the pressure sensor 406 will decrease. At this time, the controller 2 can be used to make the electric lifting rod 401 drive the support roller on the support roller seat 407 to fit with the carbon fiber prepreg and tighten it, and The spring seat 404 can also be used to increase the tolerance rate during adjustment, and the guide rod 408 can also limit and guide the support roller seat 407 and the mounting plate 405.
