DETAILED DESCRIPTION

[0051] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and cannot be understood as limiting the present invention.

[0052] In the description of the present invention, it should be understood that the terms "upper", "lower", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0053] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] The existing nozzle gap adjustment generally involves replacing nozzles with different gaps, or manually removing the nozzle, adjusting the gap, and then reinstalling it. However, this manual adjustment method is not only time-consuming and labor-intensive, but also difficult to ensure the adjustment accuracy. It cannot be automatically adjusted in time according to the needs of different stages of the process, which can easily cause dyeing quality problems and lead to problems such as fabric color and uneven operation. In order to solve the above problems, the present application proposes an adjustable nozzle for a dyeing machine, such as Figures 1 to 8 As shown, it comprises a housing 1, a static nozzle 2, a dynamic nozzle 3 and a movable mechanism 4, and the housing 1 is provided with a dye liquid inlet 5;

[0055] The static nozzle 2 and the dynamic nozzle 3 are both built into the housing 1, and one end of the static nozzle 2 and the dynamic nozzle 3 are sleeved with each other to form a nozzle gap 32. The dynamic nozzle 3 is provided with a positioning reference part, and the spacing of the positioning reference parts is distributed in the nozzle gap 32;

[0056] The movable mechanism 4 is movably mounted on the movable nozzle 3 , and the movable mechanism 4 is used to drive the movable nozzle 3 to move relative to the stationary nozzle 2 to adjust the opening and closing of the nozzle gap 32 .

[0057] Specifically, in this embodiment, the movable nozzle 3 and one end of the static nozzle 2 are mutually sleeved to form the nozzle gap 32. When the dye liquid enters the housing 1 from the dye liquid inlet 5, the movable mechanism 4 installed on the movable nozzle 3 is operated to drive the movable nozzle 3 to move relative to the static nozzle 2, so that the nozzle gap 32 between the static nozzle 2 and the movable nozzle 3 can be opened and closed.

[0058] Furthermore, when the nozzle gap 32 is opened, the dye liquid inside the housing 1 can be sprayed out from the nozzle gap 32, and when the nozzle gap 32 is closed, the dye liquid inside the housing 1 cannot be sprayed out from the nozzle gap 32;

[0059] Furthermore, the movable range of the movable structure can be adjusted to drive the movable nozzle 3 to move relative to the static nozzle 2, so as to expand or reduce the nozzle gap 32, thereby controlling the flow rate and pressure of the dye liquid inside the housing 1 sprayed from the nozzle gap 32;

[0060] In this embodiment, the movable nozzle 3 is also provided with the positioning reference member (not shown in the drawings), and the positioning reference member is provided in multiple groups, which are distributed on the inner wall of the movable nozzle 3 at circumferential intervals. It can be understood here that the positioning reference member protrudes from the inner wall of the movable nozzle 3, so that when the static nozzle 2 and the movable nozzle 3 are mutually nested, the static nozzle 2 abuts against the positioning reference member. Since the positioning reference member is distributed at intervals, a nozzle gap 32 is formed between the static nozzle 2 and the movable nozzle 3. When the static nozzle 2 abuts against the positioning reference member, the nozzle gap is the minimum gap.

[0061] Preferably, Figure 4 , Figure 7 and Figure 8 As shown, the movable mechanism 4 includes a first transmission part 41 and a second transmission part 42, and the first transmission part 41 includes a first fixed plate 410, a rotating shaft 411, a first eccentric plate 412, a first driving plate 413 and a second eccentric plate 414;

[0062] The rotating end 4110 of the rotating shaft 411 is vertically mounted on the first fixed plate 410, and the rotating end 4110 of the rotating shaft 411 is transmission-connected to the transmission end 4120 of the first eccentric plate 412 via an eccentric sleeve 415;

[0063] The driving end 4121 of the first eccentric plate 412 is movably mounted on the force-bearing end 4130 of the first driving plate 413 through a short pin 416 and a first movable roller 417;

[0064] The force-applying end 4131 of the first driving plate 413 is movably mounted on the pushing end 4140 of the second eccentric plate 414 through the short pin 416 and the external retaining spring 418;

[0065] The raised end 4141 of the second eccentric plate 414 is transmission-connected to the second transmission part 42 .

[0066] In this embodiment, since the rotating end 4110 of the rotating shaft 411 is vertically installed on the first fixed plate 410 and is transmission-connected with the transmission end 4120 of the first eccentric plate 412, rotating the rotating shaft 411 can drive the driving end 4121 of the first eccentric plate 412 to swing around its transmission end 4120; and the driving end 4121 of the first eccentric plate 412 is transmission-connected with the force-bearing end 4130 of the first driving plate 413. When the driving end 4121 of the first eccentric plate 412 swings, a swinging force can be applied to the first driving plate 413, so that the force-bearing end 4130 of the first driving plate 413 swings with the driving end 4121 of the first eccentric plate 412, thereby driving the force-applying end 4131 of the first driving plate 413 to apply a swinging force to the pushing end 4140 of the second eccentric plate 414, so that the lifting end 4141 of the second eccentric plate 414 drives the inner top shaft 420 of the second transmission part 42 to rotate;

[0067] Preferably, Figure 3 and Figure 7 As shown, the movable mechanism 4 further includes a third transmission part 43;

[0068] The second transmission part 42 includes an inner top shaft 420, a support sleeve 421 and a support frame 422;

[0069] One end of the inner top shaft 420 is fixed to the first fixed plate 410 and is in transmission connection with the top end 4141 of the second eccentric plate 414. The shaft body of the inner top shaft 420 is sleeved with the support sleeve 421.

[0070] A support sleeve 424 is installed at the other end of the inner top shaft 420, and the support sleeve 424 is sleeved with a first soft sleeve. The support sleeve 424 is sleeved on the shaft body of the inner top shaft 420 through the first soft sleeve.

[0071] The middle part of the support frame 422 is arched and half surrounds the movable nozzle 3 , the middle part of the support frame 422 is fixedly installed on the support sleeve 421 , and both ends of the support frame 422 are movably installed with the third transmission part 43 .

[0072] When the jacking end 4141 of the second eccentric plate 414 drives the inner top shaft 420 of the second transmission part 42 to rotate, the support sleeve 421 fixed to the shaft body of the inner top shaft 420 rotates synchronously, thereby driving the support frame 422 to rotate synchronously, and then driving the third transmission part 43 to transmit;

[0073] It should be noted that the middle part of the support frame 422 is arched and fixed to the support sleeve 421, so that when the support sleeve 421 rotates, the force can be fed back to the support frame 422, so as to synchronously drive the support frame 422 to rotate, and the two ends of the frame body of the support frame 422 are movably installed with the third transmission part 43 respectively, so as to disperse the rotation force to the third transmission part 43 on both sides of the moving nozzle 3, so that the third transmission part 43 can better drive the moving nozzle 3, so that the movement of the moving nozzle 3 is more stable;

[0074] In this embodiment, the support sleeve 421 is sleeved on a part of the shaft body of the inner top shaft 420, that is, the support sleeve 421 does not completely cover the entire shaft body of the inner top shaft 420, and another part of the shaft body of the inner top shaft 420 is used to sleeve the sealing sleeve 423;

[0075] Furthermore, the support sleeve 424 is provided with a first soft sleeve (not shown in the drawings), and the first soft sleeve is then sleeved on the end of the shaft body of the inner top shaft 420, and the first soft sleeve is used to connect the support sleeve 424 and the inner top shaft 420, and the support sleeve 424 is fixedly connected to the shell 1 to support the inner top shaft 420.

[0076] Preferably, Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the third transmission part 43 includes a left transmission assembly and a right transmission assembly installed on both sides of the moving nozzle 3, and the left transmission assembly and the right transmission assembly are both provided with a second driving plate 430 and a limiting fixing plate 434;

[0077] The two sides of the moving nozzle 3 are provided with limiting axes 437;

[0078] The second driving plate 430 has a mounting hole 432 in the middle of the plate body, a movable slot 431 at one end of the plate body, and a fixing hole 433 at the other end of the plate body.

[0079] The plate body of the limiting fixing plate 434 is provided with a limiting hole groove 435 and a connecting hole groove 436;

[0080] One end of the support frame 422 is movably mounted on the movable slot 431 via a second movable roller 438;

[0081] The limiting shaft 437 passes through the mounting hole groove 432 and the limiting fixing plate 434, and is limited and movable in the limiting hole groove 435;

[0082] The second driving plate 430 is movably mounted on the position-limiting fixing plate 434 by passing the fixing shaft 439 through the fixing hole 433 and the connecting hole 436;

[0083] The support frame 422 applies driving force to the second driving plate 430 through the second movable roller 438, driving the second driving plate 430 to swing around the fixed axis 439 relative to the limiting fixed plate 434, so that the second driving plate 430 drives the movable nozzle 3 to move relative to the static nozzle 2 through the limiting axis 437.

[0084] When the support frame 422 is driven to rotate, the second movable roller 438 of the frame body of the support frame 422 moves in the movable slot 431, and with the help of the limiting function of the first movable roller 417 and the movable slot 431, a swinging force is applied to the side of the second driving plate 430 where the movable slot 431 is provided. At the same time, because the fixed shaft 439 penetrates the fixed hole groove 433 and the connecting hole groove 436, and the limiting fixing plate 434 is fixed, the second driving plate 430 swings relative to the limiting fixing plate 434 with the fixed shaft 439 as the center of the circle; and because the limiting shaft 437 penetrates the mounting hole groove 432 and is limited and movable in the limiting hole groove 435, the swing amplitude of the second driving plate 430 is limited by the limiting hole groove 435. In the embodiment, the slot direction of the limiting hole slot 435 is in the up-down direction, and the slot direction of the mounting hole slot 432 is in the left-right direction; when the second driving plate 430 swings around the fixed shaft 439, the slot direction of the limiting hole slot 435 is used to limit the swing direction of the second driving plate 430 to the up-down direction, and at the same time, the slot direction of the mounting hole slot 432 is used to enable the second driving plate 430 to swing in the up-down direction, because if the mounting hole slot 432 is designed as a circular hole without a slot direction, the second driving plate 430 will not be able to swing; at the same time, the second driving plate 430 swings to apply a force to the limiting shaft 437, and because the limiting shaft 437 is fixed to the moving nozzle 3, under the force, the moving nozzle 3 can move synchronously with the second driving plate 430 to achieve movement in the up-down direction;

[0085] It should be noted that the second movable roller 438 of the frame body of the support frame 422 moves in the movable slot 431, so the swinging force applied by the support frame 422 to the second driving plate 430 through the second movable roller 438 is limited by the slot length of the movable slot 431, that is, by adjusting the position of the second movable roller 438 in the movable slot 431, combined with the limiting hole slot 435, the lifting and lowering amplitude of the second driving plate 430 can be adjusted, thereby controlling the lifting and lowering amplitude of the second driving plate 430 to drive the movable nozzle 3, thereby controlling the opening and closing degree of the nozzle gap 32.

[0086] Preferably, Figure 2 and Figure 6 As shown, the housing 1 includes a built-in chamber 11, and the built-in chamber 11 is connected to the dye liquid inlet 5;

[0087] The built-in chamber 11 is hollow inside, and has openings at its upper and lower ends, wherein the opening protrudes at the lower end and is provided with a fitting plate 12 , and an annular channel 13 is formed between the fitting plate 12 and the built-in chamber 11 .

[0088] In this embodiment, the dye liquid enters the built-in chamber 11 from the dye liquid inlet 5 . Due to the obstruction of the fitting plate 12 , the dye liquid is confined in the annular channel 13 and cannot be directly sprayed out from the opening at the lower end of the built-in chamber 11 .

[0089] Preferably, the static nozzle 2 and the dynamic nozzle 3 are both built into the built-in chamber 11;

[0090] The movable nozzle 3 includes a movable nozzle core 31, the movable nozzle core 31 is hollow inside and has openings at both the upper end and the lower end, and the opening at the lower end of the movable nozzle core 31 is connected to the through opening at the lower end of the built-in chamber 11;

[0091] The static nozzle 2 comprises a static nozzle core 21 and an anti-rotation portion;

[0092] The anti-rotation part includes a mounting plate 22 and a plurality of anti-rotation plates 23, and the anti-rotation plates 23 are vertically fixed to the mounting plate 22;

[0093] The static nozzle core 21 is truncated and is invertedly inserted into the dynamic nozzle core 31, and the anti-rotation plates 23 are distributed and scattered above the opening of the upper end of the dynamic nozzle core 31;

[0094] When the movable nozzle 3 moves relative to the stationary nozzle 2 , the nozzle gap 32 is formed at the junction of the movable nozzle core 31 and the stationary nozzle core 21 to open the opening of the upper end of the movable nozzle core 31 .

[0095] In this embodiment, after the dye enters the built-in chamber 11 from the dye inlet 5, it is blocked by the movable nozzle core 31 and the fitting plate 12, so that the dye can only flow in the annular channel 13. When the dye in the annular channel 13 increases, the movable nozzle 3 is driven by the movable mechanism 4 to move relative to the static nozzle 2, so that a nozzle gap 32 is formed at the junction of the static nozzle core 21 and the movable nozzle core 31, and the dye flows into the movable nozzle core 31 from the nozzle gap 32, that is, the dye flows in from the opening at the upper end of the movable nozzle core 31 and flows out from the opening at the lower end of the movable nozzle core 31.

[0096] Furthermore, the static nozzle core 21 is provided with a mounting plate 22, the edge of the mounting plate 22 protrudes from the outer wall surface of the static nozzle core 21, and the anti-rotation plate 23 is installed at the protruding portion of the mounting plate 22. When the static nozzle core 21 is invertedly inserted into the dynamic nozzle core 31, the anti-rotation plate 23 is distributed and interspersed above the opening of the upper end of the dynamic nozzle core 31, so that the dye liquid will not form a vortex when flowing into the nozzle gap 32.

[0097] Preferably, Figure 6 As shown, the first transmission part 41 is arranged outside the housing 1, the second transmission part 42 passes through the housing 1, and the third transmission part 43 is arranged inside the housing 1;

[0098] The housing 1 is provided with a through hole 14;

[0099] Among them, it also includes a sealing sleeve 423, which is equipped with a second soft sleeve and a seal. The sealing sleeve 423 is sleeved on the shaft body of the inner top shaft 420 of the second transmission part 42 through the second soft sleeve and the seal. One end of the inner top shaft 420 passes through the through hole 14 and is transmission-connected to the first transmission part 41, and the sleeve body of the sealing sleeve 423 passes through and is sealed and fixed to the opening of the through hole 14.

[0100] Since the inner top shaft 420 of the second transmission part 42 passes through the housing 1, in order to prevent the dye liquid inside the housing 1 from flowing out from the through hole 14, a sealing sleeve 423 is provided at the inner top shaft 420, and the sealing sleeve 423 is sleeved with a second soft sleeve (not shown in the figure) and a sealing member, and then the second soft sleeve and the sealing member are sleeved with the shaft body of the inner top shaft 420 to support the inner top shaft 420 and seal the inner top shaft 420, and at the same time, the sleeve body of the sealing sleeve 423 is connected with the orifice of the through hole 14 to play a sealing role to prevent the dye liquid inside the housing 1 from flowing out;

[0101] In this embodiment, as described above, the sealing sleeve 423 does not completely cover the entire shaft body of the inner top shaft 420 , but is only sleeved on a portion of the shaft body of the inner top shaft 420 , and the other portion of the shaft body of the inner top shaft 420 is used to sleeve the supporting sleeve 421 .

[0102] Preferably, the positioning reference member is installed at a circumferential spacing on the upper end of the movable nozzle core body 31, and the positioning reference member protrudes from the inner wall of the movable nozzle core body 31;

[0103] In this embodiment, the positioning reference part protrudes from the inner wall of the dynamic nozzle core 31, so that when the static nozzle 2 and the dynamic nozzle 3 are mutually sleeved, the static nozzle core 21 abuts against the positioning reference part. Since the positioning reference parts are distributed at intervals, a nozzle gap 32 is formed between the static nozzle core 21 and the dynamic nozzle core 31. When the static nozzle core 21 abuts against the positioning reference part, the nozzle gap is the minimum gap.

[0104] Furthermore, in the present embodiment, the installation method of the positioning reference member is a detachable installation. The detachable installation can be achieved by opening a slot hole on the wall surface of the movable nozzle core 31, and the slot hole passes through the inner and outer wall surfaces of the movable nozzle core 31. The positioning reference member is fixed to the movable nozzle core 31 by passing through the slot hole. Alternatively, a buckle is provided on the inner wall surface of the movable nozzle core 31, and the positioning reference member is designed as a buckle that can be buckled into the buckle. The positioning reference member can also be designed as a hanging member, and a hanging groove is opened on the wall surface of the movable nozzle core 31, and the positioning reference member is hung and attached to the inner wall surface of the movable nozzle core 31. Furthermore, the positioning reference member is not limited to the above structure.

[0105] In order to further understand the technical solution of the present application, the best embodiment of the present application and the drawings in the specification shall prevail, and the operating principle of the adjustable nozzle of the present application is explained as follows: It should be noted that the definition of the position in the following text shall prevail in accordance with the drawings in the specification;

[0106] like Figure 4 and Figure 8 As shown, the rotating shaft 411 is rotated counterclockwise, so that the first eccentric plate 412 swings counterclockwise, driving the first driving plate 413 to swing counterclockwise synchronously, and the first driving plate 413 applies a counterclockwise rotational force to the second eccentric plate 414, driving the inner top shaft 420 to rotate counterclockwise, that is, Figure 3 and Figure 7 As shown, the inner top shaft 420 rotates toward the direction of the moving nozzle 3 and the static nozzle 2, thereby driving the support frame 422 to swing counterclockwise. Figure 3 and Figure 5As shown, the second movable roller 438 is pressed against the left side of the movable slot 431 and applies a counterclockwise swinging force to the side of the movable slot 431 of the second driving plate 430. At the same time, since the second driving plate 430 is movably fitted to the limiting fixing plate 434 through the fixed shaft 439, when the side of the movable slot 431 of the second driving plate 430 is applied with a counterclockwise swinging force, the second driving plate 430 can be centered on the fixed shaft 439 and swing downward around the fixed shaft 439 and relative to the limiting fixing plate 434. At the same time, since the limiting shaft 437 of the second driving plate 430 is limited and movable in the limiting hole slot 43 5, and the slot direction of the limiting hole slot 435 is in the up-down direction, so when the second driving plate 430 swings downward, its left-right direction is limited, and it can only move vertically downward along the slot direction of the limiting hole slot 435, and the descending stroke is limited by the slot length of the limiting hole slot 435, thereby driving the movable nozzle core 31 fixedly connected to the limiting shaft 437 to descend vertically, while the static nozzle core 21 is stationary at this time, so that the movable nozzle core 31 moves downward relative to the static nozzle core 21, so the descent of the movable nozzle core 31 will open the nozzle gap 32, so that the dye can flow from the nozzle gap 32 into the movable nozzle core 31; conversely, the nozzle gap 32 can be reduced by the above structure;

[0107] When the positioning reference part is provided, the static nozzle core 21 may abut against the positioning reference part, so that the nozzle gap 32 is always left between the dynamic nozzle core 31 and the static nozzle core 21, that is, the nozzle gap 32 cannot be completely closed, and the nozzle gap 32 at this time is the minimum gap; when the positioning reference part is not provided, the static nozzle core 21 may completely abut against the dynamic nozzle core 31, and at this time there is no nozzle gap 32 between the dynamic nozzle core 31 and the static nozzle core 21, that is, the nozzle gap 32 at this time is completely closed.

[0108] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
