Description

Technical Field

[0001] The present application relates to the technical field of textile equipment, and in particular to a rapier loom with an improved feeding device. Background Art

[0002] Rapier loom is the most widely used shuttleless loom at present. In addition to the characteristics of high speed, high automation and high efficiency of shuttleless loom, its active weft insertion method has strong variety adaptability and can adapt to the weft insertion of various yarns. In addition, rapier loom also has obvious advantages in multi-color weft weaving, and can produce up to 16-color weft yarn yarn products. As shuttleless looms replace shuttle looms, rapier looms will become the main production machine for woven fabrics.

[0003] At present, the feeding end of the rapier loom has two directions, namely the warp feeding end located above the rapier loom for conveying the warp threads, and the weft feeding end located on one side of the rapier loom for conveying the weft threads. In the process of conveying the weft threads, a weft storage device is usually used together. The weft storage device adjusts the tension of the weft threads evenly, and then inserts the weft threads through the wire wheel to guide the weft threads into the rapier loom. However, the weft storage device and the wire wheel are usually fixed. If the weft threads of different wire diameters are replaced, the positions of the weft storage device and the wire wheel need to be fine-tuned. The workers disassemble the weft storage device and the wire wheel respectively, and then re-fix and install them in the position after disassembly. Each disassembly and reinstallation is time-consuming and labor-intensive, which affects the feeding efficiency, thereby reducing the overall processing efficiency of the equipment; therefore, further improvements can be made.

After sliding to the appropriate position, the top of the wire feeding support block 61 is locked in the third adjustment groove 11 by multiple bolt threads, thereby increasing the flexibility and adaptability of the yarn tube 64.

The rotating drive member 74 is fixed to the support connecting plate 72 by four fixing bolts. The movable end of the rotating drive member 74 is located on the side close to the support connecting plate 72, and a coupling 75 is provided on the movable end. The other end of the coupling 75 is connected to the rotating shaft passing through the support connecting plate 72, thereby realizing the rotation connection among the rotating drive member 74, the coupling 75 and the rotating plate 73, and utilizing the rotating drive member 74 to drive the rotating plate 73 to perform an active flipping action. In the present embodiment, the rotating drive member 74 is driven by a servo motor with a self-locking function. In other embodiments, other driving members may be used as drivers.

[0040] A moving ball 76 is also provided on the top of the support and fixed plate 71, and the moving ball 76 is located below the rotating plate 73. A first moving block 761 is provided at the bottom of the moving ball 76 in the vertical direction. A transverse universal joint 77 is provided at the bottom of the first moving block 761. The top of the transverse universal joint 77 is hinged to the bottom of the first moving block 761, and the moving ball 76 is restricted from making transverse movements along the length direction of the second support plate 2.

At this time, the moving support rod 78 moves laterally along the first moving groove in the rotating plate 73 arranged in the length direction of the second support plate 2, and drives the moving ball 76 to flip laterally. After flipping to a suitable position, the rotating driving member 74 arranged along the length direction of the second support plate 2 The dynamic driving member 74 drives the rotating plate 73 to flip vertically. At this time, the moving ball 76 remains stationary, and the rotating support plate moves vertically along the first moving groove in the rotating plate 73 arranged in the length direction of the second support plate 2. The bottom of the rotating support rod moves vertically along the vertical moving groove 764 on the moving ball 76, so that the weft storage device 21 can be tilted and moved within a certain angle, so that the deflection amplitude of the weft thread in the section from the weft storage device 21 to the weft-finding wheel 31 can be adjusted, and the conveying path and deflection angle of the weft thread can be flexibly adjusted according to different textile needs and fabric characteristics to meet the requirements of different textile processes.

The adjustment seat 83 is slidably arranged along the height direction of the frame 200. Two ear plates 84 are arranged on the side of the adjustment seat 83 away from the third support plate 3. The two ear plates 84 are arranged at an interval with each other, and a fastener 85 is arranged between the two ear plates 84. When the adjustment seat 83 moves to a suitable position, the two ear plates 84 are clamped by the fastener 85, so that the adjustment seat 83 is clamped and fixed on the frame 200. In this embodiment, the fastener 85 is locked and fixed by bolts; after the first adjusting slider 81 slides to a suitable position in the first adjusting slot 32, the first adjusting slider 81 is locked and fixed in the first adjusting slot 32 by using the bolt thread, thereby increasing the flexibility and adaptability of the weft-finding wheel 31.
