Drum type forming device of automotive interior trim part forming machine

Abstract

The invention provides a drum type forming device of an automotive interior trim part forming machine. The automotive interior trim part forming machine comprises a rack, a basic material supply mechanism arranged on the rack as well as a hot air supply mechanism. The drum type forming device comprises a drum supporting trolley, a drum driving mechanism, a drum and a liner tube, wherein the drum supporting trolley comprises a drum supporting trolley frame, a trolley frame left wallboard and a trolley frame right wallboard, and the drum supporting trolley frame is arranged on the rack; the drumcomprises a left drum ring, a right drum ring and a liner tube storage cage; the drum driving mechanism is connected with the right drum ring; a negative-pressure suction mechanism, a high-temperature air suction and guide-back mechanism and a cooling air suction and return mechanism are arranged on the liner tube, the negative-pressure suction mechanism is connected with a negative-pressure suction fan arranged on the rack through a pipe, the high-temperature air suction and guide-back mechanism is connected with the hot air supply mechanism through a pipe, and the cooling air suction and return mechanism is connected with an air suction fan arranged on the rack through a pipe. The requirement for high-efficiency forming of interior trim parts is met, space occupation is reduced, connection is reliable, drum motion stability is good, and the structure is compact.

Description

technical field [0001] The invention belongs to the technical field of production devices for automobile interior parts, and in particular relates to a drum-type forming device of a forming machine for automobile interior parts. Background technique [0002] Typical examples of the aforementioned automotive interior parts are automotive sound-insulating felts, but not limited to automotive sound-insulating felts, such as car floor mats, etc., whether it is sound-insulating felts or floor mats, etc., usually made of low-melting thermoplastic fibers such as polypropylene fiber, low-melting point Thermoplastic fibers mixed with natural fibers (such as one or more of hemp fibers, cotton fibers, viscose fibers and wool fibers) or chemical fibers (such as one of polyester fibers, nylon fibers and acrylic fibers) One or several kinds of mixed fibers) are obtained by heating and forming with the help of a mold. [0003] In the published Chinese patent literature, there is no lack o...

Problems solved by technology

However, the aforementioned CN102959149B is concerned with the specific structure of the drum (i.e. the drum, the same below), the structure of the drum driving mechanism that drives the drum to rotate, the transmission connection relationship between the drum and the rotating drive mechanism, and the use for sucking the basic material into the molding die and The hot air solidification of the inhaled basic material and the relevant mechanisms for cooling the sound insulation blanket formed after the hot air solidification have not given the necessary technical inspiration. The technical solutions to be introduced below are produced under this background
