Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a carbon fiber cloth impregnation quality resin pressing mechanism includes a frame 1, a first hot pressing assembly 2 is disposed on the frame 1, and a resin film unwinding device 3 is disposed on the frame 1 and above the first hot pressing assembly 2. The first hot-pressing assembly 2 includes a first bottom roller 21 rotatably coupled to the frame 1 and a first hot-pressing roller 22 positioned above the first bottom roller 21. The resin film unreeling device 3 comprises a resin material unreeling disc 31, a PE film reeling disc 32, a cold roller 33 and a turning film tearing roller 34 which are installed on the rack 1, wherein resin materials 100 on the resin material unreeling disc 31 sequentially pass through the cold roller 33 and the turning film tearing roller 34, a PE film 101 torn in a turning manner at the turning film tearing roller 34 of the resin materials 100 is reeled on the PE film reeling disc 32, and a resin layer formed by the resin materials 100 turning at the turning film tearing roller 34 and a release paper assembly 104 are impregnated and pressed with the carbon fiber cloth 200 at the first hot pressing roller 22.

The frame 1 is also provided with a cold air blowing pipe 4, and an air blowing outlet 41 of the cold air blowing pipe 4 blows air towards the resin material before reaching the cold roller 33. Preferably, the cold air source of the cold air blowing pipe 4 and the cold air source introduced into the cold roller 33 are the same air source. Before tearing the film, the resin material with the PE film unreels: the cold air blown out by the cold air blowing pipe 4 is precooled firstly, so that the temperature of the resin material 100 is reduced preliminarily, the temperature of the resin material 100 after passing through the cold roller 33 can be greatly reduced, the viscosity of the resin layer 102 on the resin material 100 is reduced to a great extent, when the PE film 101 is torn down, the resin adhered to the PE film 101 is reduced as much as possible, on one hand, the quality of the carbon fiber prepreg is effectively improved, on the other hand, the torn PE film is less in adhered resin, so that the torn PE film can be repeatedly used for preparing the resin material, the consumption of the PE film is reduced, and the production cost is favorably reduced.

The direction-changing film tearing roller 34 is arranged close to the cold roller 33, so that the temperature rise distance of the resin material after leaving the cold roller is reduced.

The blowing outlet 41 of the cold air blowing pipe 4 blows air towards the side of the resin material 100 with the PE film 101, so that the resin close to the PE film 101 is ensured to have lower temperature, and the adhesion amount is ensured to be less when the film is torn.

Referring to fig. 2, the glasses legs are arranged at left and right intervals by the cold roller 33 and the direction-changing film tearing roller 34; resin material 100 is for being the S type through cold roll 33 and diversion film tearing roller 34, and resin material 100 tears the membrane and makes the PE film 101 of tearing down upwards roll on PE film rolling dish 32 in diversion film tearing roller 34 department, and the resin layer that forms and from type paper assembly 104 for reaching first hot-pressing roller 22 downwards. Resin material 100 is tearing membrane roller 34 after the diversion, and PE membrane 101 is rolled up by PE membrane rolling disc 32, and simultaneously, the pulling force that the rolling provided is still used for lasting tearing the PE membrane down.

In the embodiment of the present invention, the frame 1 is further provided with a heating plate 5, and the heating plate 5 is located on the left side of the first bottom roller 51 on the frame 1. The heating plate 5 is used for prolonging the heating time, so that the resin and the carbon fiber cloth can be well impregnated.

Furthermore, a second hot pressing assembly 6 is arranged on the rack 1, and the second hot pressing assembly 6 is positioned on the left side of the heating plate 5 on the rack 1, so that the first hot pressing assembly 2, the heating plate 5 and the second hot pressing assembly 6 are arranged in sequence from right to left; the second hot-pressing assembly 6 comprises a plurality of second bottom rollers 61 arranged at left and right intervals, and second hot-pressing rollers 62 are correspondingly arranged above the second bottom rollers 61. After the resin and the carbon fiber cloth are sufficiently heated and impregnated by the heating plate 5, the resin and the carbon fiber cloth are hot pressed by the second hot pressing assembly 6 consisting of the plurality of second bottom rollers 61 and the plurality of second hot pressing rollers 62, so that the degree of pressing on the resin and the carbon fiber cloth is further improved.
