Description

Technical Field

[0001] The utility model relates to the technical field of textile accessories, in particular to a rear beam bracket adjusting mechanism for a textile machine. Background Art

[0002] The position of the back beam of the air jet loom has a significant impact on weaving efficiency. The position of the back beam determines the difference in tension between the upper and lower warp yarns at the shed when beating up, which has an important impact on fabric quality and weaving production efficiency. The height of the back beam position will affect the tension of the warp yarns, and thus affect the quality and style of the fabric.

[0003] Existing air-jet looms usually use cylinders at both ends of the back beam to drive the movement of the back beam bracket to achieve the purpose of adjusting the position of the back beam. However, if the position on both sides is adjusted at the same time, the positions of the back beam brackets on both sides will be inconsistent due to mechanical errors, causing the back beam to tilt. During the manufacturing process, the warp yarn will deviate, affecting the quality of the fabric. Utility Model Content

The front end of the cylinder arm of the tilting cylinder 6 is connected to the rear beam bracket 1, and the tilting angle of the tilting cylinder 6 is consistent with the extension direction of the inclined slot 7. A centering mechanism is connected between the rear beam bracket 1 and the rear beam roller 2, and the centering mechanism includes a connecting sleeve 9, a spherical roller bearing 10, a contact ring 11, a mounting ring 12 and a pressure sensor 13. The spherical roller bearing 10 includes an inner ring and an outer ring. The connecting sleeve 9 is fixedly connected to the outer ring. The connecting sleeve 9 is rotatably connected to the rear beam bracket 1, the contact ring 11 is fixedly connected to the inner ring, the mounting ring 12 is slidably connected to the outer ring, a plurality of pressure sensors 13 are provided, which are equally distributed on the circumference and are arranged on the mounting ring 12, a pressure spring 14 is connected to the pressure sensor 13, and the pressure spring 14 abuts against the contact ring 11, the rear beam roller 2 is penetrated on the inner ring, and a plurality of connecting ears 15 are provided on the outer wall of the outer ring, and a fine-tuning screw 16 is threadedly connected to the connecting ear 15, and the front end of the fine-tuning screw 16 is rotatably connected On the connecting ear 15, a plurality of guide blocks are arranged on the outer ring, a plurality of guide rods are arranged on the mounting ring 12, the guide rods are slidably inserted into the guide blocks, a mounting sleeve is arranged on the mounting ring 12, the pressure sensor 13 is fixed in the mounting sleeve, a front end of the mounting sleeve is slidably connected with a pressure contact, the pressure spring 14 abuts between the pressure contact and the pressure sensor 13, the front end of the pressure contact abuts on the contact ring 11, and a PLC controller is electrically connected between the translation cylinder 5, the tilting cylinder 6 and the pressure sensor 13.

[0025] Working principle: In the utility model, the sliding base 3 can slide left and right on the frame through the translation cylinder to adjust the left and right position of the rear beam roller 2, and the tilting cylinder 6 can make the rear beam bracket 1 relative to the sliding base 3. The rear beam roller 2 can be adjusted to any position to meet the manufacturing requirements of the fabric by using the two together.

[0026] In addition, after adjusting the position of the rear beam roller, the rear beam roller needs to be calibrated. The position adjustment on both sides of the rear beam roller will cause the rear beam roller to tilt. Since the outer ring is connected to the rear beam bracket and remains relatively horizontal, the tilt of the rear beam roller will cause the inner ring of the spherical roller bearing 10 to rotate relative to the outer ring, causing the contact ring 11 connected to the inner ring and the mounting ring 12 connected to the outer ring to tilt relative to each other. The tilted contact ring 11 will contact the pressure contact and squeeze the pressure contact to make the pressure contact shrink backward in the mounting sleeve, squeezing the pressure spring 14 and transmitting the pressure to the pressure sensor 13. When the reading of the pressure sensor 13 changes, it can be considered that the rear beam roller is in a tilted state, and the PLC controller circuit can be used to control the extension and retraction of the translation cylinder 5 and the tilting cylinder 6 to adjust the position of the two ends of the rear beam roller, so that the rear beam roller remains horizontal and the fabric manufacturing process is normal.
