Technical Field

[0001] This invention relates to the field of loom nozzle technology, and in particular to a nozzle for an air-jet loom that allows for convenient adjustment of the air jet direction. Background Technology

[0002] Air-jet looms are shuttleless looms that use jet airflow to guide the weft yarn through the shed. The loom nozzle is its most important working component. It uses the principle of air pressure to guide the yarn to the corresponding position for weft yarn. Generally, multiple sets of nozzles are set up, and the nozzles are directed in different directions as needed.

The main nozzle has an internal guide block fixedly installed inside by a threaded connection; the rear end of the main nozzle has a nozzle tube fixedly installed by a threaded connection; the rear end of the nozzle tube has a shoulder structure and fits into the assembly ring; the bottom of the main nozzle has a connector fixedly installed by a threaded connection, and the outside of the connector is sealed and rotatably connected to a flow meter.

[0006] Optionally, an extension cylinder is integrally provided on the rear side of each control seat, and a tightening screw is provided in the extension cylinder through a threaded connection.

[0007] Optionally, a three-end piston is fixedly installed inside the control seat and the extension cylinder. Both sides of the telescopic ends of the three-end piston are fixedly equipped with locking blocks, which can fit against the rotating nut. A spring is sleeved on the rear telescopic end of the three-end piston, and the rear telescopic end of the three-end piston contacts the clamping screw.

[0008] Optionally, the internal rotating part of the transmission device is equipped with a control worm gear, and a micro motor A for controlling the control worm gear is fixedly installed on one side of the transmission device; a control worm wheel is installed outside the rotating shaft of the rotating frame, and the control worm wheel is connected to the control worm gear in a transmission connection.

[0009] Optionally, the front side of the rotating frame is a U-shaped structure that curves downwards. A control screw is rotatably installed inside the lower front side of the rotating frame. A micro motor B is fixedly installed at the front end of the rotating frame. The rotating frame is connected to the control screw through a transmission. A lead screw block is installed outside the control screw through a threaded connection. A connecting rod is hinged above the lead screw block.

[0010] Optionally, each of the elevation angle frames is fixedly provided with a clamping platform at its front end. The clamping platform is fixed to the bottom of the main nozzle through a connector, and the connector connects the main nozzle to the flow meter.

[0011] Optionally, a pressure sensor is provided on the rear side of the flow meter via a threaded connection. A pressure sensor is fixedly installed inside the pressure sensor, and an inner slider is slidably installed inside the pressure sensor, which can fit against the pressure sensor.

[0012] Optionally, an outer frame is fixedly installed on the front side of the controller, one side of the outer frame bends backward, a micro electric cylinder is fixedly installed at the bend, a flow control valve block is fixedly installed at the telescopic end of the micro electric cylinder, and the flow control valve block is inserted into the controller; the controller has a channel restricted by the flow control valve block, and an integrated pipeline is installed at the front end of the controller to connect to the air source.

[0013] The beneficial effects are as follows: 1. This invention features a multi-angle adjustment function, capable of adapting to spraying needs at different angles and positions. When adjusting the spray height, tighten the clamping screw on the rear side of the selected control seat. Use the clamping screw to push the three-end piston on the rear side, squeezing the three-end piston to open the two side locking blocks. Use the locking blocks to contact the rotating screw nut, fixing the rotating screw nut. At this time, rotating the side screw can lift the control seat. Use the control worm gear to drive the control worm wheel to rotate, which can adjust the rotating frame circumferentially. The control screw drives the screw nut block to move. With the help of the connecting rod, the angle of the elevation frame can be adjusted, and the elevation angle of the main nozzle can be adjusted, ensuring complete angle control.

[0014] 2. This invention can monitor wind speed and wind pressure. After the air passes through the flow meter, the speed is measured by the impeller. Then, it passes through the connector and enters the main nozzle for jetting. During this process, pressure is applied to the inner slider, which feeds back the pressure to the pressure sensor for air pressure monitoring and feedback. If any abnormality or deviation occurs, the micro-electric cylinder can be controlled by the program to achieve automatic adjustment.

[0015] 3. In addition, the controller is connected to an external air source. When compressed air enters the controller, it passes through its internal channel and then enters the flow meter. During this process, the micro-electric cylinder is controlled to adjust the opening and closing of the flow control valve block, which can adjust the airflow speed and air pressure, realize automatic control, and ensure the normal operation of the nozzle.

[0020] The rear side of the control seat 103 is integrally provided with an extension cylinder 105, and a tightening screw 106 is provided in the extension cylinder 105 through a threaded connection.

[0021] The control seat 103 and the extension cylinder 105 are internally fixedly provided with a three-end piston 107.

The rear telescopic end of the three-end piston 107 is sleeved with a spring, and the rear telescopic end of the three-end piston 107 contacts the clamping screw 106.

[0022] The transmission device 2 has a control worm gear 201 internally rotatably mounted, and a micro motor A202 for controlling the control worm gear 201 is fixedly mounted on one side of the transmission device 2; a control worm wheel 305 is mounted on the outside of the rotating shaft of the rotating frame 3, and the control worm wheel 305 is connected to the control worm gear 201 in a transmission connection.

[0023] The rotating frame 3 has a U-shaped structure that curves downwards at the front. A control screw 301 is rotatably installed inside the lower front side of the rotating frame 3. A micro motor B302 is fixedly installed at the front end of the rotating frame 3. The rotating frame 3 is connected to the control screw 301 through a transmission. A screw nut block 303 is threadedly connected to the outside of the control screw 301. A connecting rod 304 is hinged above the screw nut block 303.

[0027] like Figure 1-8 As shown, when it is necessary to adjust the spray height, you can directly choose to use the rotation control shaft to drive the two sets of side screws 102 to rotate, and use the side screws 102 to provide drive. To lift a particular set of control seats 103, tighten the rear clamping screw 106 of that set of control seats 103. Use the clamping screw 106 to push the rear three-end piston 107, which will squeeze the rear three-end piston 107 to open the two side blocks 108. Use the blocks 108 to contact the rotating nut 104 and temporarily fix the rotating nut 104. At this time, rotating the side screw 102 can lift the control seat 103. Conversely, after unlocking the rotating nut 104, the rotating nut 104 will spin freely; Start the micro motor A202 to drive the control worm gear 201 to rotate, and use the control worm gear 201 to drive the control worm wheel 305 to rotate, so that the rotating frame 3 can be adjusted circumferentially.

[0028] Example 2: Based on Example 1, the controller 8 is connected to an external air source. When compressed air enters the controller 8, it passes through its internal channel and then enters the flow meter 6. During this process, the micro-cylinder 802 is controlled to adjust the opening and closing of the flow control valve block 803, which can adjust the airflow speed and air pressure.

[0029] Example 3: Based on Example 2, air passes through the flow meter 6 and is measured by the impeller. Then it passes through the connector 503 and enters the main nozzle 5 for jetting. During this process, pressure is applied to the inner slider 702. The inner slider 702 feeds back the pressure to the pressure sensor 701 for air pressure monitoring and feedback. If any abnormality or deviation occurs, the micro-electric cylinder 802 can be controlled by the program to achieve automatic adjustment.

[0030] The specific usage and function of this embodiment are as follows: When it is necessary to adjust the spray height, the control shaft can be rotated to drive the two sets of side screws 102 to rotate, and the side screws 102 provide the drive. To lift a set of control seats 103, tighten the clamping screw 106 on the rear side of that set of control seats 103. The clamping screw 106 pushes the rear three-end piston 107, squeezing the rear three-end piston 107 to open the two side locking blocks 108. The locking blocks 108 contact the rotating nut 104, temporarily fixing the rotating nut 104. At this time, rotating the side screw 102 can lift the control seat 103. Conversely, after unlocking the rotating nut 104, the rotating nut 104 will spin freely. Start the micro motor A202 to drive the control worm 201 to rotate, and use the control worm 201 to drive the control worm wheel 305 to rotate, so that the rotating frame 3 can be adjusted circumferentially; start the micro motor B302 to drive the control screw 301 to rotate, and the control screw 301 drives the screw nut block 303 to move, and with the help of the connecting rod 304, the angle of the elevation frame 4 can be adjusted, and the elevation angle of the main nozzle 5 can be adjusted. The controller 8 is connected to an external air source. When compressed air enters the controller 8, it passes through its internal channel and then enters the flow meter 6. During this process, the micro-electric cylinder 802 is controlled to adjust the opening and closing of the flow control valve block 803, which can adjust the airflow speed and air pressure. After passing through the flow meter 6, the air is measured by the impeller, and then passes through the connector 503 to enter the main nozzle 5 for jetting. During this process, pressure is applied to the inner slider 702, which feeds back the pressure to the pressure sensor 701 for air pressure monitoring and feedback. If any abnormality or deviation occurs, the micro-electric cylinder 802 can be controlled by the program to achieve automatic adjustment.
