[0002] Fire-resistant fabrics are widely used in fire suits, curtains, carpets, chair covers, and panel materials for hospitals, theaters, airplanes, and vehicles. For example, fire-resistant clothing such as fire suits requires strength and heat resistance and usually uses para-aramid fibers. However, the flame-retardant coating of these fibers is easily scraped off by the shed during the weaving process, which affects their flame-retardant effect. Therefore, a weaving machine for the production of fire-resistant fabrics has been proposed to solve the above problems. Utility Model Content

The hollow steel reed frame integrates a cooling air duct, which diverts cold air through the air pump to control the surface temperature of the reed body below 80°C, preventing the glass fiber weft yarn from becoming brittle due to high temperatures. The relay airflow field of the secondary nozzle group allows the flame-retardant weft yarn to pass through the shed without friction, protecting the integrity of the fiber flame-retardant coating.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the embodiments, by Figure 1Provided is a weaving machine for producing fire-resistant fabric, comprising a frame 1, a transmission mechanism 2, a warp control mechanism 3, a weft insertion mechanism 4, a beat-up mechanism 5, and an intelligent control device 6; the frame 1 comprises a high-rigidity frame consisting of box-shaped wall panels on both sides and crossbeams fixedly connected by bolts; the weft insertion mechanism 4 comprises a main nozzle, auxiliary nozzles, an air pipe, an air pump, a reed seat, a solenoid valve, an electrically controlled drum weft storage device, a servo motor, a weft brake, and a guide wheel; the main nozzle is connected to the air pump through the air pipe, and several auxiliary nozzles... The reed grooves are arranged linearly along the reed seat. The secondary nozzles have an inclination angle of 15°-30° and are connected in parallel with the main nozzles via a solenoid valve. The electrically controlled drum weft storage device is driven by a servo motor. The yarn outlet of the electrically controlled drum weft storage device is aligned with the guide wheel of the weft brake. The weft insertion mechanism 5 includes a hollow steel reed frame, a connecting rod, and a rocker shaft intermediate support frame. The hollow steel reed frame is fixed to the reed seat of the weft insertion mechanism 4 by bolts. The reed seat of the weft insertion mechanism 4 is hinged to the connecting rod. The connecting rod is connected to the crossbeam of the frame 1 via the rocker shaft intermediate support frame.

[0019] The transmission mechanism 2 includes a motor, a coupling, a main drive shaft, an eccentric rocker shaft, and bearings. The motor is connected to the main drive shaft through the coupling. The main drive shaft is hinged to the connecting rod of the weft insertion mechanism 5 through the eccentric rocker shaft. Both ends of the eccentric rocker shaft are fixed to the box-shaped wall plate of the frame 1 through bearings.

[0020] The warp control mechanism 3 includes an electrically controlled warp feeding device, a gear set, a warp shaft gear, a warp shaft, a warp release drive shaft, a chain, a tension roller, and a spring. The electrically controlled warp feeding device meshes with the warp shaft gear through the gear set to drive the warp shaft to rotate. The warp release drive shaft is connected to the tension roller through a chain, and the tension roller is elastically connected to the frame 1 through a spring.

[0021] The intelligent control device 6 includes a controller, which is embedded inside the box-shaped wall panel of the frame 1 and is electrically connected to the transmission mechanism 2, the warp control mechanism 3, the weft insertion mechanism 4, and the beating mechanism 5.

[0022] With the above structural setup, fire-retardant warp yarns (such as aramid or glass fiber) are unwound from the warp beam, tension is adjusted by an electrically controlled warp feeding device, and then fed into the weaving area via guide rollers. An electrically controlled drum weft storage device releases weft yarns (such as flame-retardant polyester) via a servo motor. The release speed of the weft yarns is precisely controlled by the guide rollers and weft yarn brakes. The main nozzles spray high-pressure airflow (0.3-0.8 MPa) under the drive of an air pump. Several auxiliary nozzles are combined into an auxiliary nozzle group, which is arranged linearly along the reed groove. The auxiliary nozzle group is opened and closed in stages by a solenoid valve to form a relay airflow field, which guides the weft yarns to pass laterally through the shed. After the weft insertion is completed, the motor drives the eccentric rocker shaft, which drives the reed seat to swing towards the weaving direction via a connecting rod. The hollow steel reed frame pushes the weft yarns toward the interlaced warp yarns, completing a single weft insertion action (frequency: 300-600 times / minute), thereby completing the weaving of the fire-retardant fabric.

[0023] It is important to note that the secondary nozzle tilt angle is 15°-30° to match the reed groove guide surface, forming a laminar flow air film, reducing friction between the weft yarn and the reed, and reducing the flame-retardant coating peeling rate by 40%. The hollow steel reed frame integrates an internal cooling air duct, which diverts cold air through an air pump to control the reed surface temperature below 80°C, preventing the fiberglass weft yarn from becoming brittle due to high temperatures. The relay airflow field of the secondary nozzle group allows the flame-retardant weft yarn to pass through the shed without friction, protecting the integrity of the fiber flame-retardant coating. The weaving navigation device automatically switches between seven different air pump supply modes according to the fabric thickness, effectively reducing compressed air consumption by approximately 30%. When the automatic cruise device detects an abnormal temperature (>150°C), it automatically cuts off the power.
