[0008] Preferably, the moving mechanism includes a hanging knife bracket suspended above the cutting station, the hanging knife bracket is provided with a knife-supporting cylinder for controlling the active knife disc to move laterally closer to or farther away from the cutting station, and a downward pressure cylinder for controlling the active knife disc to move longitudinally closer to or farther away from the cutting station; wherein, the cylinder body of the downward pressure cylinder is fixedly connected to the hanging knife bracket, the piston of the downward pressure cylinder is fixedly connected to the cylinder body of the knife-supporting cylinder, the piston of the knife-supporting cylinder is fixedly connected to the transmission shaft, and the active knife disc is connected to the transmission shaft via an active knife bearing sleeve; when the piston of the knife-supporting cylinder retracts, the active knife disc approaches the cutting station.

[0009] Preferably, a driven knife bracket is further provided at the cutting station, and the driven knife disc is rotatably arranged on the driven knife bracket via a driven knife bearing sleeve.

[0010] Preferably, the prepreg conveying mechanism further comprises a pair of first sheet-feeding auxiliary rollers disposed between the traction power roller and the cutting station, and the prepreg cloth enters along a common tangent direction of the pair of first sheet-feeding auxiliary rollers.

[0016] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0017] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] like Figure 1 and 2As shown, the trimming device for gluing prepreg in this embodiment includes a trimming mechanism and a prepreg conveying mechanism. The trimming mechanism includes an active cutter disc 1 located above the cutting station, and a driven cutter disc 2 located below the cutting station and opposite to the active cutter disc 1. The trimming mechanism also includes a moving mechanism for driving the active cutter disc 1 to feed and a driving motor 13 for driving the active cutter disc 1 to rotate, and the active cutter disc 1 is connected to the driving motor 13 through a transmission shaft.

[0019] Specifically, if Figure 2 As shown, the moving mechanism includes a hanging knife bracket (not shown) suspended above the cutting station, and the hanging knife bracket is provided with a downward pressure cylinder 12 for controlling the active knife disc 2 to longitudinally approach or move away from the cutting station, and a knife-supporting cylinder 11 for controlling the active knife disc 1 to laterally approach or move away from the cutting station. The cylinder body of the downward pressure cylinder 12 is fixedly connected to the hanging knife bracket, and the piston of the downward pressure cylinder 12 is fixedly connected to the cylinder body of the knife-supporting cylinder 11. The piston of the knife-supporting cylinder 11 is fixedly connected to the above-mentioned transmission shaft, and the active knife disc 1 is rotatably connected to the transmission shaft through an active knife bearing sleeve. When the piston of the knife-supporting cylinder 11 retracts, the active knife disc 1 approaches the cutting station. In addition, a driven knife bracket 21 (as shown in FIG. 1 ) is also provided at the cutting station. Figure 1 As shown in the figure, the driven cutter disc 2 is rotatably arranged on the driven cutter bracket 21 through the driven cutter bearing sleeve. When the active cutter disc 1 is pressed down and rotated under the drive of the driving motor 13, the semi-cured sheet cloth 100 passes between the active cutter disc 1 and the driven cutter disc 2, thereby driving the driven cutter disc 2 to rotate together.

[0020] The prepreg conveying mechanism includes a traction power roller 201 located upstream of the trimming mechanism and a rear cloth rack receiving roller 206 located downstream of the trimming mechanism. In order to ensure that the prepregs at the upstream and downstream of the cutting station remain in a tensioned state, so that the active cutter disc 1 and the driven cutter disc 2 can cut the edge of the prepreg 100 more efficiently and with high quality, a pair of first sheet feed auxiliary rollers 202, 203 are provided between the traction power roller 201 and the cutting station, and a pair of second sheet feed auxiliary rollers 204, 205 are provided between the cutting station and the rear cloth rack receiving roller 206. The prepreg 100 enters along the common tangent direction of the first sheet feed auxiliary rollers 202, 203, and then is sent out along the common tangent of the second sheet feed auxiliary rollers 204, 205.

[0021] More preferably, in order to ensure that the semi-cured fabric 100 remains taut when it reaches the cutting station and to prevent the edge of the fabric from moving due to vibration during the conveying and cutting process, the adhesive prepreg trimming device is also provided with an electric control device (not shown) for controlling the extension and retraction process of the pressing cylinder 12 and the knife cylinder 11, and a positioning device provided at the edge of the prepreg to be processed and electrically connected to the electric control device; the positioning device collects the real-time position information of the semi-cured fabric 100 at the cutting station and transmits the position information electrical signal to the electric control device, and the electric control device controls the movement process of the knife cylinder and the pressing cylinder after receiving the signal. The positioning device in this embodiment is a commercially available infrared tracker, which will not be described in detail here.

[0022] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
