Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and more specifically, to a heddle wire fixing device for a heddle loom. Background Technology

[0002] In the textile industry, the heddle loom is an important piece of machinery that uses the movement of heddles to interweave yarns and weave various fabrics. As a key component in the heddle loom that guides the movement of yarns, the fixed and tensioned state of the heddles directly affects the weaving quality and efficiency of the loom. Therefore, there is an urgent need for a heddle fixing device that can reliably fix the heddles, easily adjust the tension, and is easy to operate.

[0003] Existing heddle fixing devices for heddles looms have several problems. Firstly, traditional fixing methods struggle to ensure the heddles remain secure during long-term operation, easily leading to loosening and disrupting yarn movement, thus affecting fabric smoothness and texture uniformity, and reducing product quality. Secondly, producing fabrics of different specifications requires adjusting the heddle tension, but existing fixing devices are complex, inefficient, and unable to quickly adapt to changes in production needs, increasing production costs and extending production cycles. Utility Model Content

[0019] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0020] Please see Figure 1-4 According to an embodiment of the present utility model, a heddle wire fixing device for a heddle loom includes a heddle frame 1, a driving mechanism 2 is installed on the top of the heddle frame 1, the driving mechanism 2 drives a tensioning mechanism 3, a fixing seat 4 is installed on the tensioning mechanism 3, and a fixing mechanism 5 is installed on the fixing seat 4.

[0021] The heald frame 1 provides the mounting base and support frame for the entire heald fixing device. The drive mechanism 2 provides power for the operation of the tensioning mechanism 3. Driven by the drive mechanism 2, the tensioning mechanism 3 adjusts the tension of the heald wires. The fixing base 4 is used to install the fixing mechanism 5. The fixing mechanism 5 fixes the heald wires 20.

[0022] In this embodiment, the drive mechanism 2 includes a motor 6 installed in the top cavity of the heald frame 1. A drive wheel 7 is installed on the output shaft of the motor 6. A belt 8 is drivenly connected to the drive wheel 7. The other end of the belt 8 is drivenly connected to the driven wheel 9.

[0023] In this mechanism, motor 6 serves as the power source for drive mechanism 2, driving the drive wheel 7 to rotate via its output shaft. Driven by motor 6, the drive wheel 7 rotates and transmits power to the driven wheel 9 via belt 8. Belt 8 establishes the transmission connection between the drive wheel 7 and the driven wheel 9. Driven by belt 8, the driven wheel 9 rotates, thereby driving the bidirectional lead screw 10 to rotate.

[0024] In this embodiment, the tensioning mechanism 3 includes a bidirectional lead screw 10 installed at the bottom of the driving wheel 7 and the driven wheel 9. The upper and lower ends of the pair of bidirectional lead screws 10 are threaded with mounting strips 11, and multiple fixing seats 4 are installed at equal intervals on the facing surfaces of the pair of mounting strips 11.

[0025] The rotation of the bidirectional lead screw 10 causes the mounting strips 11 to move in opposite directions to adjust the tension of the heddle wire. The mounting strips 11 are fitted with multiple fixing seats 4 and move under the action of the bidirectional lead screw 10.

[0026] In this embodiment, the fixing mechanism 5 includes auxiliary plates 12 fixedly installed at both ends of the fixing base 4. Rotating rods 13 are installed through the auxiliary plates 12 and through rotating parts on both sides. A winding roller 14 is fixedly installed in the middle of the rotating rod 13. Insertion holes 15 are provided on the winding roller 14.

[0027] The auxiliary plate 12 provides mounting support for the rotating rod 13. The rotating rod 13 drives the winding roller 14 to rotate, which is used to wind the heddle wire 20. The winding roller 14 initially fixes the heddle wire 20 through the insertion hole 15 and winds the heddle wire while rotating. The insertion hole 15 is used to insert the heddle wire 20, realizing the initial fixation of the heddle wire 20 on the winding roller 14.

[0028] In this embodiment, a knob 16 is fixedly installed at one end of the rotating rod 13, and a ratchet 17 is fixedly installed at the other end of the rotating rod 13. The ratchet 17 engages with the limiting rod 18. The limiting rod 18 is movably connected to the locking hole 19 opened on the auxiliary plate 12. A heddle wire 20 is inserted into the connecting hole 19 and wound on the winding roller 14.

[0029] The knob 16, when manually rotated, drives the rotating rod 13 and the winding roller 14 to rotate. The ratchet 17 engages with the limiting rod 18 to prevent the winding roller 14 from rotating in the opposite direction, ensuring the heddle wires are securely fixed. The limiting rod 18 engages with the ratchet 17 to restrict the reverse rotation of the winding roller 14. The locking hole 19 is movably connected to the limiting rod 18, and the heddle wire 20 is inserted through the locking hole 19. The heddle wire 20 is a key component guiding the yarn movement in the heddle loom, fixed by the fixing mechanism 5 and its tension adjustable.

[0030] In practical applications, first insert one end of the heddle wire 20 into the insertion hole 15 of the winding roller 14, then manually rotate the knob 16 to rotate the winding roller 14, winding the heddle wire 20 onto the winding roller 14, initially fixing the heddle wire 20. Due to the cooperation of the ratchet 17 and the limiting rod 18, the winding roller 14 can only rotate in one direction, preventing the heddle wire 20 from loosening in the opposite direction. When it is necessary to adjust the tension of the heddle wire 20, start the motor 6. The motor 6 drives the drive wheel 7 to rotate, which in turn drives the driven wheel 9 to rotate through the belt 8, thereby driving the bidirectional lead screw 10 to rotate. The rotation of the bidirectional lead screw 10 causes the mounting strip 11 to move in opposite directions, thereby achieving the adjustment of the tension of the heddle wire 20.
