[0002] An air jet loom is a shuttleless loom that uses a jet of air to pull the weft yarn through the shed. Using air as the weft insertion medium, the compressed air jet creates frictional traction on the weft yarn, pulling it through the shed. The jet creates a flow that inserts the weft.

[0003] The high-pressure and high-temperature exhaust gas generated by the current air-jet loom during use is not properly recycled and is directly discharged into the air, resulting in a huge waste of kinetic energy. In addition, the dust and debris in the air are directly sprayed into the air, which will seriously affect the health of the operators. Summary of the Invention

[0027] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0028] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0029] Figure 1 、 Figure 2 and Figure 3 The exhaust port boost adjustment device shown is applied to an air jet loom, comprising a main frame 1, the exhaust port of the main frame 1 is fixedly equipped with a height-adjustable exhaust gas deflector 2, an electrically controlled lifting deflector 3 is arranged inside the exhaust gas deflector 2, and a downwardly protruding bottom cleaning cover 4 is provided on the inner bottom surface of the exhaust gas deflector 2, and an electrically controlled centrifugal cleaning brush 5 is movably installed inside the bottom cleaning cover 4.

[0030] Working principle: The exhaust gas is introduced through the air inlet of the exhaust gas deflector 2, and then the electric-controlled lifting and deflecting machine 3 is controlled to rise or fall according to the actual pressure of the exhaust gas. The electric-controlled lifting and deflecting machine 3 is then used for secondary supercharging, and the supercharged and filtered air is discharged from the air outlet of the exhaust gas deflector 2.

[0031] In order to cooperate with the internal guide, an embedded guide rail 6 is fixedly installed on the inner wall of the main frame 1, and an electric lifting screw rod 7 for controlling the lifting of the exhaust gas deflector 2 is movably installed inside the embedded guide rail 6.

[0032] In order to cooperate with the lifting and lowering adjustment, the exhaust gas deflector 2 is sleeved on the electric control lifting screw 7 through the internal thread lifting blocks on the outer walls on both sides and is threadedly assembled with the electric control lifting screw 7.

[0033] In order to cooperate with the electronically controlled lifting and adjustment, the electronically controlled lifting guide machine 3 includes a bottom lifter 31 fixed on the outer wall of the exhaust gas guide cover 2, an internal cover shell 32 fixed on the upper protruding end of the bottom lifter 31, a centrifuge 33 installed in the internal cover shell 32, and an annular metal filter cover 34 fixed at the air inlet position at the lower end of the centrifuge 33.

[0034] The bottom elevator 31 controls the internal cover 32 to rise and fall inside the exhaust gas deflector 2 by telescoping, thereby changing the internal height, thereby recovering the sinking exhaust gas and performing secondary supercharging.

[0035] In order to reduce the resistance of the windward surface and improve the internal flow guidance effect, the side wall of the internal cover 32 has an arc-shaped flow guide cover 35.

[0036] In order to cooperate with the bottom slag cleaning, the electrically controlled centrifugal cleaning brush 5 includes a bottom adjusting disk 51 arranged inside the bottom cleaning cover 4, an upper assembly seat 52 fixed to the upper end of the bottom adjusting disk 51, a cleaning brush 53 installed on the upper end of the upper assembly seat 52 and a bottom drive motor 54 fixedly hung on the lower end of the bottom cleaning cover 4.

[0037] In order to cooperate with the lateral slag collection, a lateral slag collection box 9 is fixedly assembled on the side wall of the bottom cleaning cover 4 through the lateral material guide pipe 8.

[0038] The bottom driving motor 54 drives the bottom adjusting disk 51 to rotate, and then the bottom adjusting disk 51 drives the cleaning brush 53 at the upper end of the upper assembly seat 52 to rotate slowly to clean the surface of the annular metal filter cover 34, and then rotates at high speed to guide the cleaned impurities into the inside of the lateral slag collecting box 9 through the lateral guide pipe 8.

[0039] In order to control the angle and size of the internal wind pressure, a top pressure sensor module 10 for monitoring the internal wind pressure is fixedly mounted on the upper surface of the internal cover 32 .

[0040] When the pressure of the overhead pressure sensor module 10 is small, it means that the exhaust gas pressure is sufficient and can be directly guided out from the air inlet of the exhaust gas deflector 2 to the air outlet; when the pressure of the overhead pressure sensor module 10 is large, it means that the exhaust gas pressure is insufficient, and the exhaust gas falls on the internal cover 32 at a downward angle. At this time, the bottom elevator 31 starts to extend, controls the lifting of the internal cover 32, and starts the centrifuge 32 to guide the exhaust gas into the lower end of the internal cover 32 through the arc-shaped deflector 35, and then draws it into the lower air inlet, and then is pressurized by the centrifuge 33 and discharged from the air outlet of the exhaust gas deflector 2.

[0041] In order to adjust the size and angle of the air outlet, an embedded electric-controlled exhaust cover 11 is movably mounted on the inner side of the exhaust gas deflector 2 .

[0042] In order to adjust the angle and flow rate of the air outlet, the embedded electronically controlled exhaust cover 11 includes an arc-shaped first adjustment cover 111 slidably assembled at the air outlet position on the inner side of the exhaust gas deflector 2, an arc-shaped second adjustment cover 112, and a first control motor 113 and a second control motor 114 fixed at the upper end of the exhaust gas deflector 2.

[0043] The first control motor 113 is driven by meshing the first output gear on the bottom output shaft with the arcuate tooth groove on the arcuate first adjustment cover 111 , and the second control motor 114 is driven by meshing the second output gear on the bottom output shaft with the arcuate tooth groove on the arcuate second adjustment cover 112 .

[0044] By controlling the first control motor 113 and the second control motor 114 to rotate forward and reverse, the angular position and size of the lateral air outlet of the exhaust gas deflector 2 can be changed.

[0045] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
