Technical Field

[0001] This utility model belongs to the technical field of the textile industry, specifically, it relates to a high-speed jacquard wide-width spacing adjustment device for air-jet looms. Background Technology

[0002] In modern life, high-speed air-jet looms with wide-width weaving capabilities are one of the new types of looms that have been vigorously developed in China in recent years. At present, the number of high- and mid-range air-jet looms in the domestic textile industry has reached a certain level, and the application of mechatronics technology has also reached a new height. Judging from the technical equipment level of some high-end models, the market share of air-jet looms that can adapt to the production of large jacquard fabrics and have high speed, wide width, double-width weaving and smooth edge performance is increasing. Compared with other textile machinery, the most prominent performance advantage of air-jet looms is their high weaving speed, especially air-jet looms with wide-width weaving capabilities. Their high speed can greatly improve the production efficiency of the loom. For different actual needs, such as the production of large jacquard fabrics of different widths, it is necessary to adjust the width spacing on the air-jet loom to produce large jacquard fabrics of different widths, so as to better adapt to different width requirements.

[0003] Chinese patent CN213172785U discloses a high-speed jacquard wide-width spacing adjustment device for an air-jet loom, including a base.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-5 As shown in the figure, this embodiment provides a high-speed jacquard wide-width spacing adjustment device for an air-jet loom, including: a base 1.

[0029] like Figure 1-5As shown, in this embodiment, the base 1 has a partition 2 on top, and left and right adjustment seats 5 are sleeved on both sides of the partition 2. The left and right adjustment seats 5 have a height screw 6 on top, and a height adjustment seat 7 is sleeved on the surface of the height screw 6. A mounting plate 11 is provided on one side of the height adjustment seat 7. A fixed guide wheel 12 is installed inside the mounting plate 11. A flip plate 13 is provided on the top of the mounting plate 11, and a user movable guide wheel 16 is below the flip plate 13. The height screw 6 on the partition 2 supports the height adjustment seat 7 and the mounting plate 11. The fabric passes between the movable guide wheel 16 and the fixed guide wheel 12. The fabric is clamped and transported by the rotation of the two guide wheels. The left and right adjustment seats 5 are symmetrical on the partition 2 to clamp the two ends of the fabric.

[0030] like Figure 1 , 2 As shown, the top of the flap 13 in this embodiment is provided with an adjusting rod 15; wherein, the movable guide wheel 16 is mounted on the frame, and the adjusting rod 15 at the top of the frame passes through the top of the flap 13 and is fitted onto the adjusting rod 15 by a screw sleeve. Rotating the screw sleeve engages with the thread of the adjusting rod 15, and rotating the screw sleeve raises or lowers the movable guide wheel 16 to adjust the distance between the movable guide wheel 16 and the fixed guide wheel 12, so as to facilitate the insertion of fabrics of different thicknesses.

[0031] like Figure 1 , 3 As shown in Figure 4, a double-headed screw 3 is horizontally arranged at the center of the base 1 in this embodiment, and a motor 4 is arranged on one side of the double-headed screw 3. The left and right adjustment seats 5 wrap around the partition 2, and the bottom double-headed screw 3 passes through the threaded hole at the bottom of the left and right adjustment seats 5, with the threads at both ends in opposite directions. In this way, when the motor 4 drives the double-headed screw 3 to rotate, the left and right adjustment seats 5 on both sides move in opposite directions to adjust the distance between them. At the same time, the partition 2 separates the fabric and the double-headed screw 3 to prevent debris from falling onto the double-headed screw 3 and affecting the transmission.

[0032] like Figure 1 , 2 As shown in Figure 5, the height adjustment seat 7 in this embodiment is provided with a rotating toothed sleeve 8 inside. A pin 9 is provided on one side of the rotating toothed sleeve 8, and springs 10 are provided at both ends of the pin 9 inside the height adjustment seat 7. A threaded sleeve is provided on the height screw 6, which abuts against the height adjustment seat 7. The rotating toothed sleeve 8 inside the height adjustment seat 7 also has a threaded hole and fits on the height screw 6. By rotating the corresponding threaded sleeve and the rotating toothed sleeve 8, the height of the height adjustment seat 7 and the corresponding mounting plate 11 can be adjusted, thereby adjusting the height of the fixed guide wheel 12 and the movable guide wheel 16, and thus adjusting the height of the fabric. After the height adjustment seat 7 is adjusted, the pin 9 is pushed by the spring 10, and the front end is inserted into the rotating toothed sleeve 8 to fix the rotating toothed sleeve 8, thereby fixing the height adjustment seat 7 on the height screw 6. When adjustment is needed, first loosen the threaded sleeve, then pull the pin 9 outward to compress the spring 10, and the rotating toothed sleeve 8 can be rotated to make adjustment.

[0033] like Figure 1 , 4 As shown, in this embodiment, the left and right adjustment seat 5 is fitted with a roller 17 on the top of the partition 2; wherein, the roller 17 transforms the sliding friction between the left and right adjustment seat 5 and the partition 2 into rolling friction, making the movement of the left and right adjustment seat 5 on the partition 2 smoother.

[0034] like Figure 2 As shown, in this embodiment, the side of the mounting plate 11 and the flip plate 13 are connected by a rotating shaft 14. The flip plate 13 can be flipped to one side with the rotating shaft 14 as the axis, which drives the movable guide wheel 16 to open, so that the fabric can be placed on the fixed guide wheel 12. Then, the flip plate 13 is rotated back to the center to adjust the height of the adjusting rod 15 so that the movable guide wheel 16 presses the fabric to fix it.

[0035] Working principle: Start the motor 4 to rotate the double-headed screw 3 and adjust the positions of the two left and right adjustment seats 5 to the appropriate positions. Align the fabric width with the two guide wheels, pull the pin 9 to one side, loosen the screw sleeve on the height screw 6, adjust the height of the height adjustment seat 7 on the height screw 6 to the appropriate position, and let the fabric adhere to the top of the corresponding fixed guide wheel 12. Loosen the pin 9 to fix the rotating gear sleeve 8, thereby fixing the height adjustment seat 7 and the mounting plate 11. Flip open the flip plate 13 to put the fabric in, and flip it back to adjust the height of the movable guide wheel 16 to the top of the fabric using the adjustment rod 15, thereby completing the device's adjustment and guidance of the fabric.
