Description

TECHNICAL FIELD

[0001] The utility model relates to composite board production device technical field especially relates to a kind of composite board material feeding device and continuous forming equipment. BACKGROUND

[0002] Carbon fiber reinforced composite board is widely used in aerospace, automobile manufacturing, sports equipment and many other industries due to its high strength, low density, corrosion resistance and other excellent performance. However, the existing composite unit has a large overall volume, which is inconvenient to transport. The length of the heating and cooling unit is fixed as a whole, which has poor use effect. After the equipment is lifted, the reference surface deviates, and the equipment is high on one side and low on the other side, resulting in poor product quality. The deviation of the conveyor belt causes damage to the conveyor belt. Uneven pressure causes damage to the conveyor belt and the board product, making it inevitable to develop new forming devices. Continuous preparation of carbon fiber reinforced composite board is usually produced by continuous hot pressing and cooling. The carbon fiber prepreg tape and the base material are heated, and then the roller is used for roll pressing and bonding cooling to realize continuous forming of carbon fiber composite board. However, the movement of the existing carbon fiber composite board is generally driven by a power roller. Only the power roller drives the movement of the composite board, which can easily cause the board to move off track, affecting the uniformity of roll pressing and thus affecting the quality of the composite board.

[0003] The existing patent CN202420556275.2 discloses a structure modularized thermoplastic composite press equipment, which includes a foot and a composite unit. The composite unit includes an intermediate press, an inlet end press and an outlet end press. Hydraulic cylinders are arranged on the upper ends of the frames of the intermediate press, the inlet end press and the outlet end press. The lower ends of the hydraulic cylinders are provided with upper mounting racks. The lower sides of the upper mounting racks are provided with lower mounting racks. The upper mounting racks and the lower mounting racks are provided with horizontal adjustment assemblies on the sides close to each other. The structure modularized thermoplastic composite press equipment has the intermediate press arranged between the inlet end press and the outlet end press. The inlet end press and the outlet end press are provided with a plurality of groups. The inlet end press and the outlet end press can be set according to order requirements to effectively adjust the length of the heating and cooling zones of the unit and avoid energy waste. In the above-mentioned patent, the movement of the composite board is driven by the inlet end press or the composite press. The stability of the movement of the composite board is poor, and the composite board is easily off track during movement, which affects the composite effect of the composite board.
