Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a bilateral braking system for an air-jet loom. Background Art

[0002] The air-jet loom is an important weaving equipment in the textile industry. For a loom, speed and efficiency determine the output and quality of products. While ensuring stability, weaving equipment enterprises have made great efforts in high speed and high efficiency, and achieved remarkable results. However, with the continuous increase in the loom speed, some new problems have emerged. It is mainly reflected that general looms only have a braking device in the power device. When the speed is too high and warp stop or weft stop occurs, the braking effect is obviously insufficient, and the loom is prone to slip phenomenon during braking, resulting in double weft or uneven density fabric defects, affecting the quality of the fabric. Then it is necessary for us to design a braking device to increase the braking effect and reduce such situations. Summary of the Utility Model

[0019] As Figure 1 shown, the utility model provides a bilateral braking system for an air-jet loom, including a braking device 6 and a power device 9 respectively arranged on the crankshafts on both sides of the air-jet loom frame; the braking device 6 is installed on the A side of the frame, and the power device 9 is installed on the B side of the loom frame.

[0020] Among them, as Figure 2As shown in the figure, the braking device 6 includes: a fixed block 3, a fixed disk 2, and a brake 1 mounted on the first crankshaft 4 on the A side of the loom frame. Among them, the brake 1 includes a moving piece 1b and a static piece 1a.

The fixed disk 2 and the fixed block 3 are fastened as a whole through bolts. The fixed block 3 is connected to the first crankshaft 4 of the loom through a key 5 and fastened as a whole with a first nut 7. When the loom brakes, the static piece 1a is electrified to attract and brake, and the first crankshaft 4 immediately stops running, and the loom completes the braking and stops.

[0021] In addition, as Figure 3 shown, in the present utility model, the power device 9 includes: a motor base 10 mounted on the B side of the loom frame, and a driving motor 11 is mounted on the motor base 10; the motor base 10 is fixedly mounted on the B side of the loom frame through bolts.

When the loom brakes, the rotor 11b of the driving motor 11 immediately stops running, and the first crankshaft 14 immediately stops running, and the loom completes the braking and stops. Exemplarily, the driving motor 11 is a special DC driving motor for textiles, or it can also be a special three-phase asynchronous motor for textiles.
