Description

Technical Field

[0001] This utility model relates to the field of dyeing liquor nozzles, and more particularly to a dyeing liquor nozzle for a dyeing machine. Background Technology

[0002] The airflow atomization dyeing machine uses aerodynamic principles to inject mixed air generated by a fan into the dyeing machine nozzle, which drives the fabric to move. During the dyeing process, the airflow generated by the fan enters the nozzle and meets the dye liquor delivered by the main pump inside the nozzle housing, causing the dye liquor to be atomized and sprayed onto the fabric passing through the nozzle, thus driving the fabric to move. Therefore, the fabric can obtain the best dyeing effect in the dye liquor. This equipment has the advantages of low liquor ratio, low cost, low water consumption, energy saving and environmental protection, and is widely used in the printing and dyeing industry.

[0003] Chinese patent CN201495402U discloses a nozzle for an airflow dyeing machine. This technical solution establishes a dye liquor chamber between the front nozzle cover and the positioning sleeve, where the dye liquor is stored, increasing the fluid pressure of the dye liquor. The dye liquor outlet is located on the front nozzle cover, allowing the dye liquor to be sprayed directly onto the fabric without interference from the airflow, resulting in uniform dye liquor spraying. Furthermore, the evenly distributed dye liquor outlets make the dye liquor spraying smoother and gentler.

[0004] However, during use, some dye solution remains in the nozzle after being sprayed. This residual dye solution can solidify in the nozzle, causing blockage and affecting subsequent fabric dyeing operations, which is detrimental to the operation of the dyeing machine.

[0005] Therefore, it is necessary to provide a dyeing solution nozzle for a dyeing machine to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a dyeing nozzle for a dyeing machine, which solves the problem that after the dyeing liquid is sprayed, some dye liquid remains in the nozzle, and the residual dye liquid is prone to solidification in the nozzle, causing channel blockage.

[0007] To solve the above-mentioned technical problems, the present invention provides a dyeing machine nozzle, comprising a nozzle, one end of which is provided with a nozzle head, and one end of the nozzle inner cavity is provided with an opening and closing chamber, a valve core being rotatably disposed inside the opening and closing chamber, a U-shaped member being rotatably disposed at one end of the nozzle sidewall, both ends of the U-shaped member extending rotatably into the inner cavity of the nozzle and fixedly connected to the inner end of the valve core, a driving mechanism for driving the U-shaped member to rotate being provided on the surface of the nozzle, and a liquid extraction pipe communicating with the inner cavity of the nozzle being provided at one end of the bottom of the nozzle, the liquid extraction pipe being located at one end of the valve core.

[0008] Preferably, the other end of the liquid extraction pipe is connected to a connecting pipe, and the other end of the connecting pipe is provided with a flange.

[0009] Preferably, the other end of the nozzle is connected to a connecting pipe, and the surface of the connecting pipe is provided with external threads.

[0010] Preferably, one end of the sidewall of the connecting pipe is provided with a flared pipe.

[0011] Preferably, the driving mechanism includes a fixed seat, a fixed block, and an electric telescopic rod. The fixed seat is fixedly connected to the top of the nozzle, the fixed block is fixedly connected to the top of the U-shaped part, a first connecting seat is fixedly connected to the side wall of the fixed seat, a second connecting seat is fixedly connected to the side wall of the fixed block, and the electric telescopic rod is hinged between the first connecting seat and the second connecting seat.

[0012] Preferably, both the nozzle and the spray head are coated with a nano-ceramic coating.

[0013] Compared with related technologies, the dye liquor nozzle of the dyeing machine provided by this utility model has the following beneficial effects:

[0014] This utility model provides a dyeing nozzle for a dyeing machine. After the other end of the nozzle is connected to a liquid supply device, the dyeing liquid enters the inner cavity of the nozzle through the nozzle guide, is atomized, and then sprayed out for dyeing. After dyeing is completed, the drive mechanism drives the U-shaped part to rotate, which in turn drives the valve core to rotate. After the valve core cuts off and closes the channel in the inner cavity of the nozzle, it can be connected to the liquid extraction pipe through the external negative pressure device. The liquid extraction pipe can then extract the residual dyeing liquid inside the nozzle, thereby avoiding residual dyeing liquid inside the nozzle and preventing the residual dyeing liquid inside the nozzle from solidifying and causing blockage. This is beneficial for subsequent fabric dyeing work and for the operation and use of the dyeing machine. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The dyeing machine's dyeing liquid nozzle includes a nozzle 1, one end of which is provided with a nozzle head 16, one end of the inner cavity of the nozzle 1 is provided with an opening and closing chamber 5, a valve core 6 is rotatably provided inside the opening and closing chamber 5, and a U-shaped part 7 is rotatably provided at one end of the side wall of the nozzle 1.

[0021] The two ends of the U-shaped part 7 extend rotatably into the inner cavity of the nozzle 1 and are fixedly connected to the inner end of the valve core 6. The surface of the nozzle 1 is provided with a drive mechanism for driving the U-shaped part 7 to twist. One end of the bottom of the nozzle 1 is provided with a liquid extraction pipe 8 that communicates with the inner cavity of the nozzle 1. The liquid extraction pipe 8 is located at one end of the valve core 6.

[0022] After the other end of nozzle 1 is connected to the liquid supply device, the dye liquid enters the inner cavity of the nozzle 16 through the guide of nozzle 1, is atomized and sprayed out, and can then be used for dyeing.

[0023] After dyeing is completed, the drive mechanism drives the U-shaped part 7 to rotate, which in turn drives the valve core 6 to rotate. After the valve core 6 cuts off and closes the channel inside the nozzle 1, it can be connected to the liquid extraction pipe 8 through the external negative pressure device. The residual dye liquid inside the nozzle 16 can be extracted through the liquid extraction pipe 8, thereby avoiding residual dye liquid inside the nozzle 16.

[0024] This prevents residual dye solution inside the nozzle 16 from solidifying and causing blockage, which is beneficial for subsequent fabric dyeing work and the operation of the dyeing machine.

[0025] The other end of the liquid extraction pipe 8 is connected to a connecting pipe 9, and the other end of the connecting pipe 9 is provided with a flange 10. The flange 10 facilitates the connection between external negative pressure equipment and the connecting pipe 9.

[0026] The other end of the nozzle 1 is connected to a connecting pipe 2. The surface of the connecting pipe 2 is provided with an external thread 3. One end of the side wall of the connecting pipe 2 is provided with a flared pipe 4. The external thread 3 and the flared pipe 4 facilitate the connection of different specifications of feeding pipes with the other end of the nozzle 1 to transport liquid.

[0027] The drive mechanism includes a fixed base 12, a fixed block 11, and an electric telescopic rod 14. The fixed base 12 is fixedly connected to the top of the nozzle 1, the fixed block 11 is fixedly connected to the top of the U-shaped part 7, a first connecting seat 13 is fixedly connected to the side wall of the fixed base 12, a second connecting seat 15 is fixedly connected to the side wall of the fixed block 11, and the electric telescopic rod 14 is hinged between the first connecting seat 13 and the second connecting seat 15.

[0028] After the electric telescopic rod 14 extends or retracts, it can drive the U-shaped part 7 to twist, which in turn drives the valve core 6 and the inside of the opening and closing chamber 5 to rotate, thereby opening and closing the channel inside the nozzle 1.

[0029] Both nozzle 1 and spray head 16 are coated with a nano-ceramic coating, which can reduce dye adhesion.

[0030] The working principle of the dyeing machine nozzle provided by this utility model is as follows: After the other end of the nozzle 1 is connected to the liquid supply device, the dye liquid enters the inner cavity of the nozzle 16 through the guide of the nozzle 1, is atomized and sprayed out, and can be used for dyeing. After dyeing is completed, the drive mechanism drives the U-shaped part 7 to rotate, which in turn drives the valve core 6 to rotate. After the valve core 6 cuts off and closes the channel of the inner cavity of the nozzle 1, it can be connected to the liquid extraction pipe 8 through the external negative pressure device. The residual dye liquid inside the nozzle 16 can be extracted through the liquid extraction pipe 8, thereby avoiding the residual dye liquid inside the nozzle 16.

[0031] Compared with related technologies, the dye liquor nozzle of the dyeing machine provided by this utility model has the following beneficial effects:

[0032] After the other end of nozzle 1 is connected to the liquid supply device, the dye liquid enters the inner cavity of nozzle 16 through the guide of nozzle 1, is atomized and sprayed out, and can be used for dyeing. After dyeing is completed, the drive mechanism drives the U-shaped part 7 to rotate, which in turn drives the valve core 6 to rotate. After the valve core 6 cuts off and closes the channel of the inner cavity of nozzle 1, it can be connected to the liquid extraction pipe 8 through the external negative pressure device. The residual dye liquid inside nozzle 16 can be extracted through the liquid extraction pipe 8, thereby avoiding the residual dye liquid inside nozzle 16 from solidifying and causing blockage, which is beneficial to the subsequent fabric dyeing work and the operation of the dyeing machine.
