Technical Field

[0001] The utility model relates to the technical field of papermaking production auxiliary equipment, in particular to an air blowing device for water needle roll changing. Background Art

[0002] Water needle roll changing is an automated technology used to change paper rolls during the papermaking process. It uses high-pressure water as a cutting medium to separate the paper web from the old roll and transfer it to the new roll, thus achieving paper-free roll changing, reducing paper waste and equipment maintenance requirements.

[0003] In the textile industry, roll changing in water-jet production lines is a crucial step that directly impacts production continuity and efficiency. Currently, traditional roll changing methods mostly rely on manual handheld high-pressure nozzle operation, which is not only labor-intensive but also prone to downtime due to untimely roll changing.

The top of the L-shaped fixing plate 5 is fixedly connected to a semi-adjusting roller 20, and the outer side of the semi-adjusting roller 20 is fixedly connected to a worm gear 9. Both sides of the semi-adjusting roller 20 are fixedly connected to a side plate 8, and a U-shaped plate 12 is slidably installed between the tops of the two side plates 8. Two straight pipes 13 are fixedly connected to the top of the U-shaped plate 12, one of which is fixedly installed with a high-pressure nozzle 14 at one end close to the textile frame 1, and a worm gear is rotatably installed on the inner wall of the U-shaped plate 12. Rod 15, worm 15 is meshed with worm wheel 9. When the water cutting angle of high-pressure nozzle 14 needs to be adjusted, the worm 15 can be rotated to cause the spiral shape of worm 15 to mesh with the tooth surface of worm wheel 9, producing a transmission effect, so that the spiral surface of worm 15 can move along the teeth of worm wheel 9, thereby driving U-shaped plate 12 and the high-pressure nozzle 14 above it to slide on side plate 8, so that the appropriate cutting and blowing angle can be adjusted according to actual production needs. In the above structure, no manual hand-held adjustment is performed, thereby reducing the labor intensity of the staff and making timely adjustments to production to avoid downtime.

[0033] Reference Figure 2The interior of the mounting plate 2 is provided with a lateral adjustment component, which includes a bidirectional screw rod 4 rotatably connected to the interior of the frame groove 19, and a limit rod 3 is fixedly connected to the interior of the frame groove 19 and below the bidirectional screw rod 4. The two L-shaped fixing plates 5 are respectively threadedly connected to the two ends of the outer side of the bidirectional screw rod 4, and the L-shaped fixing plates 5 are slidably connected to the limit rod 3. When the old paper roll needs to be peeled off, the two L-shaped fixing plates 5 can be driven to gather toward the middle by rotating the bidirectional screw rod 4, so that the position of the straight tube 13 can be adjusted, and then the purpose of peeling off the old paper roll can be achieved. The above structure reduces the manual operation space, saves time and effort, and improves work efficiency.

[0034] Reference Figure 3 A limiting component is provided inside the side panel 8, and the limiting component includes a limiting groove 2 10 opened inside the side panel 8. The limiting groove 2 10 is slidably connected to the limiting block 11 inside. The two limiting blocks 11 are respectively fixedly connected to the two ends of the bottom of the U-shaped plate 12. Through the coordinated use of the limiting groove 2 10 and the limiting block 11, the movement trajectory of the U-shaped plate 12 can be limited. An important role can be played, thereby ensuring the normal operation of the high-pressure nozzle 14.

[0035] Reference Figure 4 , an anti-winding component is provided inside the mounting plate 2, and the anti-winding component includes a receiving groove opened inside the mounting plate 2 and located on one side of the frame groove 19, the inner wall of the receiving groove is slidably connected to a limiting plate 18, and a limiting groove 7 is opened inside the mounting plate 2 and located between the receiving groove and the frame groove 19, and a bellows 17 is fixedly connected between the two straight pipes 13, wherein one section of the straight pipe 13 extends to the interior of the receiving groove and is fixedly connected to the limiting plate 18. When the straight pipe 13 and the high-pressure nozzle 14 move laterally, the limiting plate 18 will be driven to move in the receiving groove, and the role of the receiving groove can have a receiving effect on the water inlet pipe, and through the coordinated use of the limiting groove 7 and the limiting plate 18, a certain limiting effect can be played to prevent the water inlet pipe from being affected by the movement of the straight pipe 13 and causing anti-winding.

[0036] Reference Figure 4 The side of the limiting plate 18 away from the straight pipe 13 is fixedly connected to the water inlet pipe. The limiting plate 18 is a hollow structure. Through the setting of the hollow structure, water can be transported to the inside of the straight pipe 13 through the water inlet pipe and the limiting plate 18.

[0037] Reference Figure 3 A servo motor 2 is fixedly installed on one side of the U-shaped plate 12 close to the L-shaped fixed plate 5. The output shaft of the servo motor 2 is fixedly connected to the corresponding worm 15. The rotation of the output shaft of the servo motor 2 can drive the worm 15 to rotate.

[0038] Reference Figure 3, scale lines 16 are fixedly connected to both sides of the side plate 8. By setting the scale lines 16, the rotation angles of the high-pressure nozzle 14 and the U-shaped plate 12 can be accurately controlled.

[0039] Reference Figure 1 A servo motor 6 is fixedly installed on the outside of the mounting plate 2. The output shaft of the servo motor 6 extends to the inside of the frame groove 19 and is fixedly connected to the bidirectional screw rod 4. The rotation of the output shaft of the servo motor 6 can drive the bidirectional screw rod 4 to rotate, thereby realizing power transmission.

[0040] Working principle: First, when the old paper roll needs to be peeled off, the servo motor 6 can be controlled by the external control device to start, and the output end of the external water pump is connected to the water inlet pipe. Then, through the rotation of the bidirectional screw rod 4, the two L-shaped fixing plates 5 can be driven to gather toward the middle, so that the position of the straight pipe 13 can be adjusted. Then, the bidirectional screw rod 4 is controlled to rotate in the opposite direction, and the external water pump is controlled to supply water, so that the L-shaped fixing plates 5 and the straight pipe 13 are reset, thereby achieving the purpose of peeling off the old paper roll. The above structure reduces the manual operation space, saves time and effort, and improves work efficiency.

[0041] When the water cutting angle of the high-pressure nozzle 14 needs to be adjusted, the output shaft of the servo motor 2 can be controlled to rotate. Through the rotation of the worm 15, the spiral shape of the worm 15 is engaged with the tooth surface of the worm wheel 9, producing a transmission effect, so that the spiral surface of the worm 15 can move along the teeth of the worm wheel 9, thereby driving the U-shaped plate 12 and the high-pressure nozzle 14 above it to slide on the side plate 8, so that the appropriate cutting and blowing angle can be adjusted according to actual production needs;

[0042] When the straight pipe 13 and the high-pressure nozzle 14 move laterally, the limiting plate 18 will be driven to move in the receiving groove. The receiving groove can store the water inlet pipe, and the cooperation of the limiting groove 7 and the limiting plate 18 can play a certain limiting role, thereby preventing the water inlet pipe from being affected by the movement of the straight pipe 13 and causing anti-entanglement.
