[0005] Specifically, the technical problem to be solved by this utility model is to provide a fiber optic strand combing device for automotive glass fiber chopped mat, so as to solve the current technical problem that uneven bundling leads to local fiber agglomeration and affects the wettability of the strand comb.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A fiberglass chopped strand mat filament bundling and combing device for automotive applications includes a frame, a bundling mechanism mounted on the frame, and a combing mechanism mounted on the frame, wherein the bundling mechanism and the combing mechanism are arranged in parallel.

[0008] The beam splitting mechanism consists of several tapered beam splitting needles driven by the first drive assembly and beam splitting auxiliary rollers driven by the same power.

[0009] The combing mechanism includes movable comb teeth installed inside the frame, and the movable comb teeth are driven and adjusted by a second drive component.

[0010] As an improved technical solution, the first drive assembly includes a first drive motor mounted on the frame, a rotating rod vertically and rotatably mounted on the inner side of the frame, and one end of the rotating rod being connected to the output shaft of the first drive motor. A plurality of the tapered splitting needles are arranged in a circular array on the rotating rod along the axial direction of the rotating rod.

[0011] A drive pulley is fixedly installed on the outer surface of the rotating rod, and a driven pulley is fixedly installed on the outer surface of the beam splitting auxiliary roller. The beam splitting auxiliary roller is vertically and rotatably installed on the inner side of the frame, and the beam splitting auxiliary roller is arranged parallel to the rotating rod. Belts are installed on the drive pulley and the driven pulley.

[0012] As an improved technical solution, the surface of the conical beam splitter is coated with a diamond-like carbon film.

[0013] As an improved technical solution, the outer surface of the rotating rod is provided with snap-fit ​​holes arranged in a ring array along the axial direction of the rotating rod. The bottom of the tapered beam splitter has an integrally formed snap-fit ​​post that corresponds to the snap-fit ​​hole, and the snap-fit ​​post is adapted to the snap-fit ​​hole. The tapered beam splitter is detached and installed on the rotating rod through the snap-fit ​​post and the snap-fit ​​hole.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are:

[0018] 1. This utility model involves connecting the glass fiber chopped strand mat filaments to be bundled to an external winding device via a rotating rod and a bundling auxiliary roller. The first drive motor is then started, causing its output shaft to rotate the rotating rod. This rotating rod, in turn, rotates the conical bundling needles, thus bundling the glass fiber chopped strand mat filaments. Simultaneously, the rotating rod drives the drive pulley to rotate, which in turn drives the driven pulley to rotate. The driven pulley then rotates the bundling auxiliary roller, which assists in conveying the bundled glass fiber chopped strand mat filaments. During this process, the uniformity of the bundled glass fiber chopped strand mat filaments can be altered by disassembling the conical bundling needles arranged in a circular array along the axial direction of the rotating rod, thereby facilitating and ensuring uniform bundling of the filaments.

[0019] 2. In this utility model, by starting the second drive motor, the output shaft of the second drive motor drives the lead screw to rotate, the lead screw drives the moving column to move, and the moving column drives the comb tooth protrusion to move. During this period, the lead screw drives the moving column to move along the outer surface of the slide bar to change the density of the movable comb teeth until the density of the movable comb teeth is adjusted to the required density. Then, the bundled glass fiber chopped mat filaments are combed by the movable comb teeth to achieve the combing of the glass fiber chopped mat filaments, thereby facilitating the adjustment of the density of the movable comb teeth and thus facilitating the combing of the glass fiber chopped mat filaments.
