Description

Technical Field

[0001] This invention belongs to the field of fiber composite material design and manufacturing, and in particular relates to a continuous cutting and winding device for sheet molding compound and its cutting and winding method. Background Technology

[0002] Fiber composites are increasingly used across various industries due to their lightweight and high strength. The molding processes and methods for different fiber composite products vary. Traditional materials such as metals and ceramics, due to their isotropic nature, are not constrained by processing direction, but they also lose design flexibility. In contrast, fiber composites are anisotropic, highly designable, and can fully utilize their design performance to maximize lightweight design. Sheet molding compounds, as a semi-prefabricated fiber composite material, are widely used in the design and manufacture of fiber composite products.

[0003] To accurately achieve the product design shape and avoid performance loss due to secondary processing, sheet molding compounds need to be pre-cut into shapes that meet design requirements. With the development of production processes and production needs, the emergence of automatic material handling machines has met the cutting needs of small-sized sheet molding compounds, but it cannot cut sheet molding compounds longer than 2 meters or extra-long ones. This raises the question of how to cut long and extra-long materials. Summary of the Invention

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a method for cutting and winding sheet molding compound, specifically including the following steps:

[0006] (1) After placing and fixing the bracket, feeding device, feeding platform, receiving bracket and receiving device, the sheet molding compound passes through the feeding platform under the roller meter and connecting rod, and is placed at the pusher rolling groove position on the cutting pad. The roller pusher is pushed along the pusher rolling groove by the pusher handle to cut and trim the sheet molding compound.

[0007] (2) Turn on the roller meter counter, set the parameters according to the required material length, pull the sheet molding compound to wind onto the take-up cylinder of the take-up device, and stop pulling the sheet molding compound according to the prompt sound of the roller meter counter after each set length. Push the roller-type pusher along the pusher rolling groove through the pusher handle to cut the sheet molding compound. After meeting the requirements, rewind and replace with a new take-up cylinder.

[0008] A cutting and winding device used in a sheet molding compound cutting and winding method includes a feeding device, a feeding platform, a roller meter counter, a connecting plate, a cutting pad and a roller pusher, a winding bracket, a winding device and a winding core. The feeding device is installed at the front end of the feeding platform and the winding device is installed at the rear end. The cutting pad is placed on the feeding platform. The roller meter counter, the connecting plate and the roller pusher are installed on the feeding platform. The winding core is installed inside the winding device.

[0009] Furthermore, the feeding device includes a main shaft, a left support ring fixed threaded rod, a retaining ring, a rotating support core, and a support ring.

The support core and bearing support surface are connected; the retaining ring is inserted into the main shaft from both ends to the bearing, and the retaining ring fixing nut is inserted into the main shaft from the left end to the retaining ring and tightened. The second retaining ring fixing nut is inserted into the main shaft from the right end to the retaining ring and tightened. The retaining ring is fixed by the first and second retaining ring fixing nuts respectively, ensuring that the ball bearing is fixedly clamped at the support ring and the rotating support core, realizing the rotation of the rotating support core; the dimensions of the rotating support core are designed in coordination with the dimensions of the sheet molding compound core, and the sheet molding compound support surface and... The spacing between the inner diameters of the sheet molding compound cores is 5mm-10mm; the connected main shaft is inserted into the sheet molding compound core, aligning the center of the rotating support core with the center of the sheet molding compound; the sheet molding compound support surface of the rotating support core rests within the sheet molding compound core and connects to the rotating support core under the weight of the sheet molding compound. When the sheet molding compound is pulled, the ball bearings rotate under the tension of the sheet, achieving coordinated rotation of the rotating support core and the sheet molding compound with the ball bearings; respectively...
