Description

Technical Field

[0001] The utility model relates to the technical field of direct-drive motors for water jet looms, in particular to a direct-drive motor control device for water jet looms. Background Art

[0002] The water jet loom is a shuttleless loom that uses jet water to pull the weft yarn through the shed. The frictional traction of the weft yarn by water jet is greater than that of the weft yarn by air jet, and the diffusion is small. It is suitable for the weft insertion of smooth synthetic fibers, glass fibers and other filaments. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving. In addition, the energy consumed by jet weft yarn is less and the noise is the lowest.

[0003] In the prior art, the patent number CN216056674U, "A direct drive motor control device for water jet looms", can directly connect the drive motor to the main transmission shaft through a plug rod and a slot. In order to prevent dust from entering the slot, a limited block is used for sliding connection in the slot, and a protruding structure is set on the edge of the main transmission shaft to prevent the limit block from sliding out, so that the contact position between the plug rod and the main transmission shaft is at the protruding structure, which affects the transmission effect. In addition, the motor is not dustproof. Utility Model Content

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] See also Figures 1 to 5 The embodiment of the present application provides a direct-drive motor control device for a water jet loom, including a body 1, a main transmission shaft 2, and a driving motor 12. A slot 3 is provided at one end of the main transmission shaft 2, and a rotating shaft 4 is rotatably connected in the slot 3. The rotating shaft 4 is arranged oppositely, and a baffle 5 is installed on the rotating shaft 4. One end of the baffle 5 arranged oppositely is abutted. A vortex spring 6 is installed on the rotating shaft 4, and one end of the vortex spring 6 is connected to the main transmission shaft 2. A dustproof box 7 is installed on the body 1, and a plurality of gears 8 are rotatably connected to the body 1. A plurality of connecting shafts 9 are rotatably connected to the dustproof box 7. The gear 8 is connected to the connecting shaft 9 and is coaxially arranged. A dustproof plate 10 is installed on the connecting shaft 9, and the dustproof plate 10 is matched with the dustproof box 7. A slide plate 11 is slidably connected to the body 1, and the driving motor 12 is installed on the slide plate 11. Racks 13 are installed on both sides of the slide plate 11, and the racks 13 are meshed with a plurality of gears 8 on the same side.

[0022] In this embodiment, when the drive motor 12 is plugged and driven with the main transmission shaft 2, the drive motor 12 on the sliding plate 10 is moved toward the main transmission shaft 2, and the plug rod on the drive motor 12 squeezes the baffle 5 installed in the slot 3 on the main transmission shaft 2, and the baffle 5 rotates through the rotating shaft 4, and finally one side of the baffle 5 abuts against the inner wall of the slot 3, and the other side abuts against the plug rod, so that when the drive motor 12 drives the main transmission shaft 2 through the plug rod, the plug rod abuts against the inner wall of the main transmission shaft 2 through the baffle 5 up and down, and the two sides of the plug rod directly abut against the inner wall of the main transmission shaft 2, thereby improving the stability during transmission. When the drive motor 12 is moved out, the vortex spring 6 pulled by the rotation of the rotating shaft 4 shrinks, so that the baffle 5 is reset to prevent dust in the slot 3. When the slide plate 11 moves outward, the racks 13 on both sides drive the gear 8 to rotate, and the gear 8 drives the dustproof plate 10 on the connecting shaft 9 to rotate, so that the inside of the dustproof box 7 is connected to the outside for heat dissipation. When the slide plate 11 drives the driving motor 12 to retract, it drives the gear 8 to rotate, so that the dustproof plate 10 is reset and the dustproof box 7 is in a closed state again.

[0023] In some embodiments, in order to further improve the stability of the drive motor 12 and the main transmission shaft 2 during transmission, a limit groove 14 is provided on the dustproof box 7, the limit groove 14 is arranged oppositely, a limit block 15 is installed in the limit groove 14, a spring 16 is installed in the limit groove 14, one end of the spring 16 is connected to the limit block 15, and an extrusion block 17 is installed on the slide plate 11. The end of the limit block 15 closer to the extrusion block 17 is chamfered, and after the extrusion block 17 squeezes the limit block 15 to shrink the spring 16, the limit blocks 15 on both sides squeeze and rub the extrusion block 17, so that the slide plate 11 is stably transmitted under the cooperation of the limit block 15 and the gear 8.

[0024] In some embodiments, in order to facilitate the slide plate 11 to drive the driving motor 12 to move, a linear driving device 18 is installed on the main body 1. The linear driving device 18 can be an electric cylinder, and the output end of the linear driving device 18 abuts against the slide plate 11.

[0025] In some embodiments, in order to protect the linear drive device 18, a U-shaped block 19 is installed on the slide plate 11, and a U-shaped block 20 is installed on the output end of the linear drive device 18, and the U-shaped block 19 and the U-shaped block 2 are arranged in coordination. This prevents the linear drive device 18 from directly contacting the slide plate 11, thereby preventing the vibration of the drive motor 12 from affecting the linear drive device 18 when it is working.

[0026] In some embodiments, in order to facilitate the retraction of the baffle plate 5 into the main transmission shaft 2 , an abutment port 21 is provided on the main transmission shaft 2 , and the width of the abutment port 21 is the same as the thickness of the baffle plate 5 .

[0027] In some embodiments, to facilitate the rotation of the dustproof plate 10, both ends of the dustproof plate 10 are chamfered.
