Description

Technical Field

[0001] This utility model belongs to the technical field of air-jet loom testing equipment, specifically relating to an air-jet loom nozzle testing device. Background Technology

[0002] In the textile industry, air-jet looms have become one of the mainstream weaving equipment due to their advantages such as high weaving speed, high degree of automation, and wide range of adaptable fabrics. They are widely used in the production of various fabrics, including cotton, chemical fibers, and blends. The nozzle (including the main nozzle and auxiliary nozzles) is the core actuator of the air-jet loom. Its main function is to guide the weft yarn through the warp opening by ejecting high-pressure airflow, completing the introduction and positioning of the weft yarn. The airflow performance of the nozzle (such as airflow pressure stability and flow uniformity) directly determines the weft yarn flight speed, positioning accuracy, and weaving continuity. If the nozzle has problems such as airflow leakage, excessive pressure loss, or abnormal flow, it can easily lead to weft yarn breakage, weaving defects (such as missing weft or weft shrinkage), and other faults, seriously affecting fabric quality and production efficiency. Therefore, regular performance testing of the nozzles is a key aspect of air-jet loom maintenance.

[0003] However, existing testing devices often use fixtures with fixed specifications, which can only accommodate main or auxiliary nozzles of a single size or a few sizes. Since nozzles (especially auxiliary nozzles) on different models of air-jet looms vary in diameter, length, and interface structure, testing different nozzle sizes requires frequent disassembly and replacement of the corresponding fixtures. This is not only cumbersome and time-consuming, but also potentially leads to installation errors in the fixtures affecting the testing benchmark, further reducing testing reliability. Meanwhile, nozzle testing requires simulating actual working conditions, introducing a stable high-pressure airflow (typically 0.5-0.8 MPa), and collecting airflow parameters using sensors such as electronic flow meters and electronic pressure gauges to determine nozzle performance. However, most existing devices lack effective air source filtration structures, allowing dust and metal debris from the external compressed air source to easily enter the testing system with the airflow. This can clog the sensing channels of electronic flow meters and pressure gauges, causing sensor malfunction or data drift. Furthermore, impurities adhering to the inner wall of the nozzle can alter the actual airflow channel cross-section, interfering with the true spray state and ultimately leading to significant errors in the test data (with some devices exhibiting error rates exceeding 5%), making it impossible to accurately determine whether the nozzle is faulty. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, the purpose of this invention is to provide a nozzle detection device for an air-jet loom, which solves the technical problems of poor fixture adaptability, cumbersome operation and easy to affect the detection benchmark of the existing nozzle detection device, as well as the presence of impurities in the air source, which leads to large error in detection data and easy sensor failure.

A second T-shaped column 10 is attached, and the surface of the second T-shaped column 10 is slidably connected to the inner wall of the second T-shaped groove 9. A circular hole 11 is opened inside the clamping plate 8, and a cylinder 12 is fixedly connected to the inner wall of the circular hole 11. Rectangular holes 13 are opened on both the left and right sides of the rectangular tube 7, and the inner wall of the rectangular hole 13 is slidably connected to the surface of the cylinder 12. A second electric telescopic rod 14 is fixedly connected to the front of the U-shaped plate 6. A connecting block 15 is fixedly connected to the telescopic end of the second electric telescopic rod 14 and the inner wall of the rectangular tube 7. A detection mechanism 16 is fixedly connected to the upper surface of the base plate 1. A conical tube 17 is fixedly connected to the right side of the detection mechanism 16, and a rubber tube 18 is bonded to the inner wall of the conical tube 17.

[0028] The testing mechanism 16 includes an electronic flow meter 161, a first horizontal pipe 162, a second horizontal pipe 163, a first support block 164, a second support block 165, a vertical pipe 166, and an electronic pressure gauge 167. The inlet end of the electronic flow meter 161 is fixedly connected to the right end of the first horizontal pipe 162, and the outlet end of the electronic flow meter 161 is fixedly connected to the left end of the second horizontal pipe 163.

The inner walls of the two support blocks 165 are fixedly connected. The bottom of the first support block 164 and the bottom of the second support block 165 are both fixedly connected to the upper surface of the base plate 1. The right end of the second horizontal tube 163 is fixedly connected to the surface of the conical cylinder 17. The bottom end of the vertical tube 166 is fixedly connected to the upper surface of the second horizontal tube 163.

The vertical tube 166 and the second horizontal tube 163 are perpendicular to each other.

[0029] The width of the rectangular hole 13 is equal to the diameter of the cylinder 12, the length of the rectangular hole 13 is greater than the diameter of the cylinder 12, and the angle between the rectangular hole 13 and the horizontal plane is 45°.

[0030] It should be noted that the slider 3 is controlled to move left or right by the first electric telescopic rod 2. The slider 3 can only move left and right by the cooperation of the first T-shaped groove 4 and the first T-shaped post 5. The clamping plate 8 can only move back and forth by the cooperation of the second T-shaped groove 9 and the second T-shaped post 10. There are two clamping plates 8. When the rectangular cylinder 7 moves downward, the distance between the two clamping plates 8 is reduced by the cooperation of the inclined rectangular hole 13 and the cylinder 12. The two clamping plates 8 clamp the main nozzle or auxiliary nozzle of any size. When the rectangular cylinder 7 moves upward, the distance between the two clamping plates 8 is increased by the cooperation of the inclined rectangular hole 13 and the cylinder 12. The two clamping plates 8 release the main nozzle or auxiliary nozzle. The rectangular cylinder 7 is controlled to move up and down by the second electric telescopic rod 14.

[0031] When the main nozzle or auxiliary nozzle is clamped by the two clamping plates 8, the end of the main nozzle or auxiliary nozzle can be made to contact or separate from the inner wall of the rubber cylinder 18 by the first electric telescopic rod 2. When the end of the main nozzle or auxiliary nozzle contacts the inner wall of the rubber cylinder 18, the airflow in the detection mechanism 16 can enter the main nozzle or auxiliary nozzle through the conical cylinder 17. The flow rate of the main nozzle or auxiliary nozzle during operation can be collected by the electronic flow meter 161, and the air pressure at the inlet of the main nozzle or auxiliary nozzle can be collected by the electronic pressure gauge 167.

[0032] A cylinder 19 is fitted to the inner wall of the first horizontal tube 162. A filter screen 20 is fixedly connected to the inner wall of the cylinder 19. A groove 21 is opened on the left side of the first horizontal tube 162. A U-shaped column 22 is fixedly connected to the surface of the cylinder 19. The surface of the U-shaped column 22 fits against the inner wall of the groove 21. A bolt 23 is fitted to the inner wall of the U-shaped column 22. A nut 24 is threadedly connected to the surface of the bolt 23. A connecting plate 25 is fixedly connected to the right side of the nut 24 and the surface of the first horizontal tube 162.

[0033] Among them, a retaining ring 26 is fixedly connected to the inner wall of the first horizontal tube 162, and rubber rings 27 are fitted to the left side of the retaining ring 26, the inner wall of the first horizontal tube 162, and the right side of the cylinder 19.

[0034] It should be noted that when the U-shaped post 22 is inserted into the groove 21, the groove 21 can align the U-shaped post 22 with the nut 24. When the bolt 23 passes through the U-shaped post 22 and is screwed into the nut 24, the cylinder 19 can be fixed inside the first horizontal tube 162 through the cooperation of the bolt 23, the U-shaped post 22 and the nut 24. After the cylinder 19 is fixed inside the first horizontal tube 162, the cooperation of the retaining ring 26 and the rubber ring 27 can prevent air from leaking out from the contact surface between the cylinder 19 and the first horizontal tube 162.

[0035] After the cylinder 19 is fixed inside the first horizontal tube 162, the filter screen 20 inside the cylinder 19 can filter impurities in the air source, preventing impurities from clogging the electronic flow meter 161, the electronic pressure gauge 167, or affecting the nozzle detection status, thereby reducing the detection data error rate to ±2%.

[0036] The working principle of this utility model is as follows: First, insert the cylinder 19 into the first horizontal tube 162 and make the U-shaped column 22 contact the groove 21. Then, pass the bolt 23 through the U-shaped column 22 and screw it into the nut 24. At this time, the cylinder 19 can be fixed in the first horizontal tube 162 by the cooperation of the bolt 23, the U-shaped column 22 and the nut 24.

[0037] Then, the main nozzle or auxiliary nozzle to be tested is placed between the front and rear clamping plates 8, and the rectangular cylinder 7 is moved downward by the second electric telescopic rod 14. At this time, the distance between the front and rear clamping plates 8 is reduced by the cooperation of the inclined rectangular hole 13 and the cylinder 12, and the main nozzle or auxiliary nozzle of any size is clamped by the two clamping plates 8. After the main nozzle or auxiliary nozzle is clamped by the two clamping plates 8, the end of the main nozzle or auxiliary nozzle is made to contact the inner wall of the rubber cylinder 18 by the first electric telescopic rod 2. After the end of the main nozzle or auxiliary nozzle contacts the inner wall of the rubber cylinder 18, the airflow in the detection mechanism 16 can enter the main nozzle or auxiliary nozzle through the conical cylinder 17.

[0038] Then, connect the left end of the cylinder 19 to an external compressed air source and adjust the air source pressure to the actual working pressure of the air-jet loom (usually 0.5-0.8 MPa). At this time, impurities in the air source can be filtered through the filter screen 20 inside the cylinder 19. At the same time, the airflow enters the main nozzle or auxiliary nozzle through the first horizontal pipe 162, the electronic flow meter 161, the second horizontal pipe 163 and the conical cylinder 17. The flow rate of the main nozzle or auxiliary nozzle during operation is collected by the electronic flow meter 161, and the air pressure at the inlet of the main nozzle or auxiliary nozzle is collected by the electronic pressure gauge 167. Then, based on the values ​​measured by the electronic flow meter 161 and the second electronic pressure gauge 167, it is determined whether the tested main nozzle or auxiliary nozzle is faulty.

[0039] After the main nozzle or auxiliary nozzle under test is tested, the external compressed air source is turned off. Then, the end of the main nozzle or auxiliary nozzle is separated from the inner wall of the rubber cylinder 18 by the first electric telescopic rod 2, and the rectangular cylinder 7 is moved upward by the second electric telescopic rod 14. At this time, the distance between the front and rear clamping plates 8 is increased by the cooperation of the inclined rectangular hole 13 and the cylinder 12, and the two clamping plates 8 are released from the main nozzle or auxiliary nozzle.

[0040] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
