Description

An air-jet loom with adjustable air outlet position Technical Field

[0001] This utility model relates to the field of air-jet loom technology, specifically an air-jet loom with adjustable air outlet position. Background Technology

[0002] Air-jet looms use compressed air as the weft insertion method. The friction between the jet airflow and the weft yarn generates traction force, which carries the weft yarn into the shed and completes the weft insertion process. Air-jet weft insertion has high requirements for the quality of the raw yarn and semi-finished products. For weft yarns with high linear density or special fancy yarns, there may be insufficient traction force. There are many different types of air-jet looms on the market.

[0003] As disclosed in CN214168271U, this invention relates to the field of air-jet loom technology and provides a device for adjusting the spray position of auxiliary nozzles in an air-jet loom. The device includes an auxiliary nozzle mounting frame, a nozzle connector rotatably mounted on the front side of the mounting frame via a bearing, a nozzle replacement component on the side of the nozzle connector, an auxiliary nozzle body detachably mounted on the top of the nozzle replacement component, a mounting plate detachably mounted laterally on the front side of the mounting frame, and a transmission component above the mounting plate and located at the bottom of the nozzle connector. The bottom end of the transmission component has a toothed plate with a toothed groove. This device for adjusting the spray position of auxiliary nozzles in an air-jet loom allows the position of the auxiliary nozzles to change through the rotation of the transmission component, thus enabling adjustments based on the airflow from the main nozzle during weaving, improving practicality.

[0004] The existing technology has the following technical problems: When adjusting the position of the nozzles, it is not convenient to adjust the spacing between the nozzles. As a result, when the spacing difference is inconsistent, it is easy to cause inconsistent airflow transmission speed, which affects the speed at which multiple weft threads enter the shed.

[0005] However, conventional air-jet looms do not allow for easy adjustment of the air outlet position. Consequently, when the required length of the weft yarn after forming varies, the air outlet position of the weft yarn may be too far or too close. It is also difficult to adjust the air outlet angle. As a result, when the airflow pressure is too high, it may affect the weft yarn's passage through the shed, making it difficult to prevent the weft yarn from shifting during the forming process. Consequently, gaps may appear in the position of the formed weft yarn. Therefore, we propose an air-jet loom with an adjustable air outlet position to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an air-jet loom with an adjustable air outlet position, in order to solve the problem mentioned in the background art that the air outlet position of conventional air-jet looms is not easy to adjust. As a result, when the required length of the weft yarn after forming is different, the air outlet position of the weft yarn is often far or close, making it difficult to adjust the air outlet angle. Consequently, when the airflow pressure is too high, it can easily affect the weft yarn passing through the shed, making it difficult to prevent the weft yarn from shifting during the forming process. This can easily lead to gaps in the position of the formed weft yarn during the forming process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an air-jet loom with adjustable air outlet position, comprising:

[0008] The nozzle body has an air jet installed at its lower end and an air pipe fixedly connected to its lower end.

[0009] Also includes:

[0010] A first threaded rod, the upper end of which is provided with a nozzle body, and a grooved plate is fixedly connected to the outer side of the upper end of the first threaded rod, and a sliding column is slidably connected to the inner side of the grooved plate;

[0011] The rotating rod has a first threaded rod at its lower end and an angle adjustment mechanism for adjusting the jet angle on its outer side. The angle adjustment mechanism includes a grooved rod, a slider, and a hydraulic rod. The nozzle body is connected to the outer side of the rotating rod via a slot, and the grooved rod is fixedly connected to the outer front end of the rotating rod. The slider is slidably connected to the inner side of the lower end of the grooved rod.

[0012] A positioning clamp is provided on the lower right end of the rotating rod to prevent weft yarn deviation.

[0013] Preferably, the outer side of the first threaded rod is threadedly connected to the inside of the left end of the base, and the outer sides of the front and rear ends of the groove plate are slidably connected to the inside of the front and rear ends of the left side of the base, and the right end of the sliding column is fixedly connected to the moving plate.

[0014] Preferably, the sliding column is slidably connected to the inner side of the groove plate at equal angles, and a rotating rod is rotatably connected to the upper end of the moving plate, and both the upper and lower ends of the moving plate are slidably connected to the outer side of the fixed column.

[0015] Preferably, the outer front end of the slider is slidably connected to the inner front end of the fixing frame.

[0016] Preferably, a hydraulic rod is fixedly connected to the lower end of the slider, and a fixed frame is fixedly connected to the rear end of the hydraulic rod. A fixed column is fixedly connected to the inner side of the fixed frame, and the outer sides of the front and rear ends of the rotating rod are rotatably connected to the inner sides of the upper end of the fixed frame, respectively.

[0017] Preferably, the outer end of the positioning clamp is internally threaded with a second threaded rod, and the upper end of the motor is fixedly connected to a fixing slot frame, and the lower end of the fixing slot frame is fixedly connected to a base, and the upper right side of the base is fixedly connected to a roller.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the adjustable air outlet loom can quickly adjust multiple air outlet positions, and can also prevent excessive gaps between air outlets from affecting the weft insertion effect. It can adjust the air outlet angle, reduce nozzle pressure and adjust the nozzle pressure position to ensure that the weft yarn can fly straight and prevent the weft yarn from deviating during the weft yarn forming process.

[0019] 1. It is equipped with a base, a first threaded rod and a groove plate. By rotating the first threaded rod, the groove plate fixedly connected to the upper end of the first threaded rod moves up or down, and drives the outer sides of the front and rear ends of the groove plate to slide up or down inside the front and rear sides of the left end of the base, so that the sliding column slides on the inner side of the groove plate, and can adjust multiple air outlet positions at the same time.

[0020] 2. It is equipped with a sliding column, a movable plate and a fixed column. By moving the sliding column, the movable plate fixedly connected to the right end of the sliding column moves at the same time and slides on the outside of the fixed column, which drives the nozzle body connected to the outer groove of the rotating rod to slide. This can make the spacing between the air outlets the same while adjusting the air outlet position, thus increasing the weft insertion effect.

[0021] 3. It is equipped with a rotating rod, a grooved rod, and a slider. By activating the hydraulic rod, the slider fixedly connected to the upper end of the hydraulic rod moves. When the outer rear end of the slider slides on the inner side of the lower end of the grooved rod, the grooved rod flips up or down and drives the rotating rod fixedly connected to the rear end to rotate, so that the nozzle body connected to the groove on the outer side of the rotating rod flips to the opposite direction to the grooved rod, which can automatically control the air outlet angle.

[0022] 4. It is equipped with a slider, a hydraulic rod and a fixed frame. By activating the hydraulic rod, the slider fixedly connected to the upper end of the hydraulic rod moves up or down. At this time, the outer side of the front end of the slider slides on the inner side of the front end of the fixed frame to position the slider and accurately control the air outlet angle.

[0023] 5. Equipped with a motor, a second threaded rod, and positioning clamps, starting the motor drives the second threaded rod fixedly connected to the lower end of the motor to rotate. When the second threaded rod rotates, it drives the two positioning clamps connected to the outer thread of the second threaded rod to move inward or outward, which can prevent the weft yarn from running off-center, resulting in gaps after the weft yarn is formed.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please refer to Figures 1-6. This utility model provides a technical solution: an air-jet loom with adjustable air outlet position, including a base 1, a first threaded rod 2, a grooved plate 3, a sliding column 4, a moving plate 5, a fixed column 6, a nozzle body 7, a rotating rod 8, a grooved rod 9, a slider 10, a hydraulic rod 11, a fixed frame 12, an air pipe 13, an air jet 14, a fixed grooved frame 15, a motor 16, a second threaded rod 17, a positioning clamping plate 18, and a winding roller 19;

[0033] Existing air-jet looms are not convenient for adjusting the air outlet position. As a result, when the required length of the weft yarn after forming is different, the air outlet position of the weft yarn may be far or close. It is also not convenient to adjust the air outlet angle. Therefore, when the airflow pressure is too high, it may affect the weft yarn passing through the shed. It is not easy to prevent the weft yarn from shifting during the forming process. As a result, gaps may appear in the position of the formed weft yarn during the forming process.

[0034] The base 1 has a first threaded rod 2 internally threaded to the upper left side, and a groove plate 3 is fixedly connected to the upper outer side of the first threaded rod 2. The outer sides of the front and rear ends of the groove plate 3 are slidably connected to the inner sides of the front and rear ends of the base 1. A sliding column 4 is slidably connected to the inner side of the groove plate 3, and a movable plate 5 is fixedly connected to the right end of the sliding column 4. Fixed columns 6 are rotatably connected to the upper and lower ends of the movable plate 5, and fixed brackets 12 are fixedly connected to the front and rear ends of the fixed columns 6.

[0035] When the air outlet position needs to be adjusted, the first threaded rod 2, which is internally threaded at the left end of the rotating base 1, moves the grooved plate 3, which is fixedly connected to the upper end of the first threaded rod 2, upward or downward. When the grooved plate 3 moves downward, the sliding column 4 slides downward inside the grooved plate 3. At this time, the movable plate 5, which is fixedly connected to the right end of the sliding column 4, slides outside the fixed column 6. At the same time, the outer sides of the front and rear ends of the grooved plate 3 move downward inside the front and rear ends of the base 1, and the distance between the movable plates 5, which are slidably connected to the outer side of the fixed column 6, increases. When the grooved plate 3 moves upward, the sliding column 4 slides upward inside the grooved plate 3. At this time, the movable plate 5, which is fixedly connected to the right end of the sliding column 4, slides outside the fixed column 6. At the same time, the outer sides of the front and rear ends of the grooved plate 3 move upward inside the front and rear ends of the base 1, and the distance between the movable plates 5, which are slidably connected to the outer side of the fixed column 6, decreases. This allows for quick adjustment of multiple air outlet positions and also prevents excessive differences in the spacing between air outlets, which could affect the weft insertion effect.

[0036] The movable plate 5 has a rotating rod 8 rotatably connected to its upper end, and a nozzle body 7 is arranged in an array on the outer side of the rotating rod 8. The outer side of the rotating rod 8 is slidably connected to the upper end of the movable plate 5. A groove rod 9 is fixedly connected to the front end of the rotating rod 8, and a slider 10 is slidably connected to the lower end of the groove rod 9. The outer side of the front end of the slider 10 is slidably connected to the inner side of the front end of the fixed frame 12. A hydraulic rod 11 is fixedly connected to the lower end of the slider 10, and a fixed frame 12 is fixedly connected to the rear end of the hydraulic rod 11. An air pipe 13 is fixedly connected to the lower side of the nozzle body 7, and an air jet 14 is fixedly connected to the lower end of the air pipe 13. The lower end of the air jet 14 is fixedly connected to the base 1.

[0037] When the air outlet angle needs to be adjusted, the jet injector 14 is activated, and the airflow is delivered to the nozzle body 7 through the air pipe 13 fixedly connected at the upper end. The hydraulic rod 11 is then activated. When the hydraulic rod 11 pushes the slider 10 upwards, the outer front end of the hydraulic rod 11 slides upwards on the inner side of the upper end of the fixed frame 12, and the outer rear end of the slider 10 slides upwards on the inner side of the lower end of the groove rod 9, causing the groove rod 9 to flip upwards. At this time, the rotating rod 8 fixedly connected to the rear end of the groove rod 9 rotates in the same direction, and the nozzle body 7 fixedly connected to the inner side of the rotating rod 8 flips downwards. After the pressure rod 11 pulls the slider 10 downward, the outer front end of the hydraulic rod 11 slides downward on the inner side of the upper end of the fixed frame 12, and the outer rear end of the slider 10 slides downward on the inner side of the lower end of the groove rod 9, causing the groove rod 9 to flip downward. At this time, the rotating rod 8 fixedly connected to the rear end of the groove rod 9 rotates in the same direction, and the nozzle body 7 connected to the outer slot of the rotating rod 8 flips upward. At the same time, the outer side of the rotating rod 8 is rotatably connected to the inner side of the upper end of the moving plate 5, which can adjust the air outlet angle, reduce the nozzle pressure, and adjust the nozzle pressure position to ensure that the weft yarn can fly straight.

[0038] A fixed slot frame 15 is fixedly connected to a motor 16 at its upper end, and a second threaded rod 17 is fixedly connected to the lower end of the motor 16. A positioning clamp 18 is threadedly connected to the outer side of the second threaded rod 17. The outer sides of the upper and lower ends of the second threaded rod 17 are rotatably connected to the inner sides of the upper and lower ends of the fixed slot frame 15, respectively. The fixed slot frame 15 is symmetrically arranged on the front and rear sides of the upper end of the base 1. The lower end of the fixed slot frame 15 is fixedly connected to the base 1, and a roller 19 is rotatably connected to the upper right side of the base 1.

[0039] When it is necessary to prevent weft yarn deviation, the motor 16 is started, which drives the second threaded rod 17 fixedly connected to the lower end of the motor 16 to rotate. This causes the two positioning clamps 18 threadedly connected to the outer side of the second threaded rod 17 to move outward or inward respectively. At the same time, the outer end of the positioning clamp 18 is slidably connected to the inner side of the motor 16, so that one end of the weft yarn is wrapped around the outer side of the winding roller 19. The outer sides of the front and rear ends of the weft yarn at the position where it has just been woven are tightly attached to the positioning clamps 18. After the weft yarn begins to be woven, the positioning clamps 18 continuously rotate the winding roller 19 to wind up the woven weft yarn, which can prevent deviation during the weft yarn forming process.

[0040] Operating Procedure: Wrap one end of the weft yarn around the outside of the winding roller 19, and tightly attach the upper and lower outer ends of the weft yarn close to the winding roller 19 to the positioning clamps 18. Depending on the thickness of the weft yarn, start the motor 16 to rotate the second threaded rod 17, causing the positioning clamps 18, threaded to the outside of the second threaded rod 17, to move inward or outward simultaneously within the fixed groove frame 15, thus limiting the weft yarn. Install the other end of the weft yarn onto the loom. Adjust the air outlet position according to the required length of the formed weft yarn. Rotate the first threaded rod 2, causing the groove plate 3, fixedly connected to the upper end of the first threaded rod 2, to move upward or downward. When the groove plate 3 moves, it causes the sliding column 4 inside the groove plate 3 to slide. Adjust the distance between the multiple moving plates 5, causing the moving plates 5 to move to a position outside the fixed column 6. The moved plate 5 pushes the nozzle body 7 to the required position outside the rotating rod 8, and starts the jet 14. The air pipe 13 fixedly connected to the upper end delivers airflow to the interior of each nozzle body 7. The airflow ejected from the nozzle body 7 introduces the weft yarn into the shed. When it is necessary to reduce the airflow pressure, the hydraulic rod 11 is activated, which drives the slider 10 fixedly connected to the upper end of the hydraulic rod 11 to move up or down. The outer side of the front end of the slider 10 slides up or down inside the groove rod 9, and drives the rotating rod 8 fixedly connected to the rear end of the groove rod 9 to rotate. The nozzle body 7 connected to the slot outside the rotating rod 8 is flipped to different directions to adjust the air pressure generated by the airflow on the weft yarn, so that the weft yarn completes the gradual forming process.
